* chore(web): remove dead legacy client-side plugin-config generator (~2,300 lines)

Plugin config forms have been rendered server-side (plugin_config.html via
GET /partials/plugin-config/<id>) since the HTMX migration; the old
client-side generator survived as unreachable code. Verified dead by call
graph, not by naming: showPluginConfigModal and showGithubTokenInstructions
have zero callers anywhere in templates or JS, and everything removed here
is reachable only from those two roots.

Removed:
- plugins_manager.js: showPluginConfigModal, generatePluginConfigForm,
  generateFormFromSchema, generateFieldHtml, generateSimpleConfigForm,
  handlePluginConfigSubmit, the modal's JSON-editor view (initJsonEditor,
  switchPluginConfigView, syncFormToJson/JsonToForm, saveConfigFromJsonEditor,
  resetPluginConfigToDefaults, displayValidationErrors, closePluginConfigModal,
  savePluginConfiguration, currentPluginConfigState), their exclusive helpers
  (getSchemaPropertyType, escapeCssSelector, dotToNested, collectBooleanFields,
  normalizeFormDataForConfig, flattenConfig, loadCustomHtmlWidget), the
  orphaned-modal cleanup block, the modal's listener wiring, and the
  never-invoked showGithubTokenInstructions/closeInstructionsModal pair.
- plugins.html: the #plugin-config-modal markup those functions drove.
- base.html: the deprecated pluginConfigData() component and the
  window.PluginConfigHelpers shim (only ever called by pluginConfigData).

Deliberately kept, verified still live:
- renderArrayObjectItem, getSchemaProperty, escapeHtml/escapeAttribute
  (window-exposed for the top-level array-of-objects handlers the
  server-rendered form uses), toggleNestedSection, addKeyValuePair/
  addArrayObjectItem families, executePluginAction, and
  window.currentPluginConfig = null init (file-upload.js and
  executePluginAction read it, optional-chained).
- app()'s internal generateConfigForm/generateSimpleConfigForm methods in
  base.html: unreachable now but embedded in the live Alpine component;
  excising methods from a live object is deferred to keep this change
  zero-risk.

Validation: every deletion seam inspected line-by-line; Jinja parse of both
templates passes; repo-wide sweep confirms zero remaining references to any
deleted function or element id (deleted ranges contained no Jinja tags).

* feat(web): mobile navigation drawer + responsive CSS gap fixes

Phones previously got the desktop layout squeezed: ~12 system tabs plus one
tab per installed plugin wrapped into many rows of small pill buttons, and
the header's settings-search and system-stats widgets were dropped entirely
(hidden below their breakpoints, never relocated).

- Off-canvas nav drawer below md: the existing nav markup (system tab row +
  #plugin-tabs-row, including dynamically injected plugin tabs) is wrapped in
  a #site-nav container that CSS repositions into a slide-in drawer on small
  screens. Same DOM nodes, same @click handlers, nothing duplicated. Tabs
  become full-width rows with 44px+ touch targets. A hamburger button
  (md:hidden) in the header and a backdrop toggle the new mobileNavOpen
  Alpine state (added to both app() definitions, mirroring activeTab).
  Clicking any tab, a search result, or the backdrop closes the drawer.
  At md+ hard CSS guards make all drawer styles inert - desktop renders
  exactly as before.
- Header widgets relocated, not hidden: placeHeaderWidgets() in app.js moves
  the #settings-search-wrap and #system-stats nodes (same elements, listeners
  intact - both are looked up by id from SSE/search code, so they must never
  be duplicated) into the drawer below md and back into the header above it,
  via a matchMedia listener.
- Fixed 13 breakpoint utility classes that templates referenced but app.css
  never defined (sm:block, sm:grid-cols-2, sm:text-sm, md:block, md:w-auto,
  lg:block, lg:flex, lg:w-64, xl:grid-cols-2/3, 2xl:grid-cols-2/3/4). This
  was a live bug: 'hidden sm:block' on the search box and 'hidden lg:flex'
  on the stats meant BOTH were invisible at every screen width. Audit method
  (repeatable): diff classes used in templates vs defined in app.css.
- Mobile modal sizing: one global rule caps .modal-content at 95vw/90vh with
  internal scroll below 640px - covers every modal without per-template
  changes.
- Horizontal-scroll affordance: pure-CSS edge-fade shadows on
  .overflow-x-auto containers (scrolling-shadows technique), plus larger
  in-table touch targets below md.

Validation: breakpoint used-vs-defined audit now returns zero gaps; Jinja
parse of base.html passes; all changes to desktop behavior are additive
(new utilities) or scoped inside max-width media queries.

* feat(web): x-advanced schema flag groups plugin config fields under a collapsed Advanced Settings section

Plugin config pages show every schema property at equal visual priority,
which overwhelms first-time users. Plugin authors can now add
"x-advanced": true to any flat (non-object) property in config_schema.json
to move it into one collapsed "Advanced Settings (N)" section rendered after
the basic fields - progressive disclosure with zero loss of control.

Implementation: the main render loop in plugin_config.html splits ordered
properties into basic/advanced tiers; the advanced group reuses the exact
.nested-section/.nested-content/toggleSection() shell that nested object
sections already use, so the settings search's expand-on-match behavior
works on advanced fields with no JS changes. Object-type properties ignore
the flag (they already render as their own collapsible sections). No
backend change needed: jsonschema ignores unknown x-* keywords exactly as
it does for x-widget/x-propertyOrder.

Documented in docs/widget-guide.md alongside the other x-* extensions.

Validation (rendered with real Jinja, not just parsed):
- synthetic schema with 2 advanced fields: basic fields render before the
  section, advanced inside the collapsed shell, count badge correct,
  x-advanced on an object property correctly ignored
- schema without any x-advanced: output is identical to the pre-change
  template (whitespace-normalized diff against git HEAD's version)

* feat(web): Display Settings basic/advanced split + live total-resolution readout

The Hardware Configuration card showed ~17 fields at equal priority; a new
user only needs 7 of them to get a correctly-sized, correctly-colored image
(rows, cols, chain_length, parallel, brightness, hardware_mapping,
led_rgb_sequence). The other 10 (multiplexing, panel_type, row_address_type,
gpio_slowdown, rp1_rio, scan_mode, pwm_bits, pwm_dither_bits,
pwm_lsb_nanoseconds, limit_refresh_rate_hz) now live in a collapsed
"Advanced Hardware Settings" section using the same nested-section shell as
plugin config forms, so toggleSection() and settings-search auto-expand work
unchanged. led_rgb_sequence moved up beside brightness/hardware_mapping
(2-col grid became 3-col). No field was removed or renamed; the form still
posts the same names to /api/v3/config/main.

Also adds a live "Your display: W x H pixels" readout under the four sizing
fields (width = cols x chain_length, height = rows x parallel - the exact
math the chain-length tooltip describes in prose), recomputed client-side on
every input event, no round-trip.

Deviation from plan, deliberate: disable_hardware_pulsing / inverse_colors /
show_refresh_rate stay in their separate "Display Options" card rather than
moving across cards - relocating fields between form sections risks
regressions for no decluttering gain in the card users complained about.

Validation (real Jinja render): all 17 hardware fields present exactly once,
basic fields render before the advanced section and the 10 advanced fields
inside it, div count balanced (71/71), readout + recompute script present.

* feat(web): plugin install auto-enables + persistent restart nudge

Getting a plugin onto the display used to take three disconnected manual
steps: install from the store, flip its enable toggle, then restart the
display service - with no in-UI hint that steps 2 and 3 were needed (only
docs/GETTING_STARTED.md mentions it).

- installPlugin() now enables the plugin immediately on successful install
  (owner-confirmed behavior change: always auto-enable, no opt-out; users
  who don't want it running toggle it off as before), then shows a
  persistent toast ("... restart the display to show it") with an inline
  "Restart Now" button wired to the existing restartDisplay() - the same
  function the three existing Restart Display buttons call.
- notification.js: show() accepts optional { actionLabel, onAction } to
  render one inline action button per toast. Callbacks are stored per
  notification id and cleaned up on dismiss; a new triggerAction() public
  method runs the callback and dismisses. The global showNotification()
  shorthand now forwards a full options object as its second argument
  (legacy type-string calls unchanged).

Scope note: applies to the plugin store's install path (window.installPlugin).
The custom-registry install path keeps its existing behavior.

* feat(web): dismissible Getting Started checklist on Overview

New users land on a dense multi-tab dashboard with no suggested order of
operations (the only guided flow is the WiFi captive portal). This adds a
non-gating checklist card at the top of Overview with five steps, each a
deep link that switches to the right tab (and closes the mobile nav drawer):

1. Set panel size            -> Display tab   (done: rows/cols/chain_length > 0)
2. Set timezone/location     -> General tab   (done: differs from template
                                               defaults America/New_York / Tampa)
3. Install a plugin          -> Plugins tab   (done: /api/v3/plugins/installed
                                               non-empty)
4. Enable a plugin           -> Plugins tab   (done: any installed plugin enabled)
5. Configure it              -> Plugins tab   (done: first enabled plugin has >=1
                                               saved value differing from its
                                               schema defaults)

Steps 1-2 are computed server-side in Jinja from main_config (already in the
partial's context); 3-5 client-side from existing endpoints. No new backend
state: dismissal persists in localStorage (mirroring the reconciliation
banner's sessionStorage pattern one section up); deep links use the same
_x_dataStack app-data access as settings-search.js. Disclosed heuristic
limit: values left at legitimate defaults (a user actually in Tampa) read
as "not done".

Validation: real Jinja render across 3 config variants confirms the
server-side done-flags flip correctly; div balance intact; /plugins/config
response shape (config dict directly in .data) verified against api_v3.py.

* feat(display): drag-and-drop plugin rotation order for the primary display mode

The primary rotation's order was invisible and unconfigurable: modes are
registered in parallel-load COMPLETION order, so rotation order actually
varied between restarts. Only the niche Vegas Scroll mode had a working
order UI. This adds real, persisted ordering end to end:

Backend:
- config.template.json: new display.plugin_rotation_order (default [],
  fully backward compatible).
- display_controller.py: _apply_plugin_rotation_order() rebuilds
  available_modes grouped by plugin per the configured list (each plugin's
  modes keep their declared order; unlisted plugins follow in existing
  relative order; empty config = exact no-op). Applied at startup after
  parallel load and after live enable/disable reconcile (before the
  existing _resync_mode_index_after_change, which preserves the current
  mode). Mirrors vegas_mode get_ordered_plugins() semantics.
- api_v3.py save_main_config: accepts plugin_rotation_order as a JSON
  array (same parse/guard pattern as vegas_plugin_order).

Frontend:
- New shared widget static/v3/js/widgets/plugin-order-list.js: the Vegas
  section's drag-and-drop list factored out verbatim (native HTML5 drag
  events, saved-order-first rendering, hidden-input JSON sync),
  parameterized by container/order-input/optional exclude-checkbox/badge.
- display.html: Vegas section now calls the shared module; its ~130-line
  inline copy of the same logic is deleted.
- durations.html: new "Rotation Order" card above the durations grid using
  the same module, posting plugin_rotation_order with the existing form.

Deviation from plan, deliberate: durations stay as their own mode-keyed
grid rather than inline in the drag rows - verified display_durations keys
are MODE names (display_controller.py resolves duration per mode_key), not
plugin ids, and one plugin can own several modes, so the planned 1:1
inline pairing was wrong.

Validation: py_compile on both Python files; _apply_plugin_rotation_order
unit-tested standalone (configured order applied, empty-config no-op,
unknown ids skipped - 3/3); both templates render with balanced divs, the
hidden input carries the saved order, and the old inline implementation is
confirmed gone; config.template.json parses.

* feat(web): serve the interface at / — /v3 kept as a legacy alias

The user-visible URL no longer carries the interface version: the pages
blueprint is now registered un-prefixed (primary) AND at /v3 (second
registration, name='pages_v3_legacy'), so:

- http://<device>/ serves the interface directly (the old @app.route('/')
  redirect is removed — the blueprint's own index takes its place)
- every existing /v3/... bookmark and all the hardcoded /v3/partials/...
  fetches in templates/JS keep working verbatim through the alias mount —
  zero template/JS churn, zero broken links
- url_for('pages_v3.*') resolves against the primary registration, so all
  server-side redirects (captive portal detection endpoints) now emit
  un-prefixed URLs
- the AP-mode captive-portal allowlist learned the un-prefixed page paths
  (/setup, /partials/, /settings/, /plugin-ui/) so setup-mode requests
  don't redirect-loop
- /api/v3 and the templates/v3, static/v3 directories are deliberately
  untouched (internal, invisible to users; owner-confirmed scope)

Validation: dual registration mechanics tested against real Flask (test
client): /, /v3, /v3/ redirect, partials and /setup reachable on both
mounts, url_for yields un-prefixed paths; py_compile passes.

* perf(web): stream the preview PNG raw instead of PIL decode + re-encode

display_preview_generator() opened each changed snapshot with PIL and
re-encoded it to PNG just to base64 it — but /tmp/led_matrix_preview.png
already IS a PNG, written atomically by the display service (tmp file +
os.replace in display_manager.py), so a partially-written file can never be
observed. Read the bytes and base64 them directly: identical payload
(front-end consumes data:image/png;base64 — verified in base.html), one
full image decode+encode per frame less on the same Pi that's driving the
matrix. The existing mtime skip and viewer-marker throttling are unchanged
(they already covered the "skip unchanged frames" concern).

* perf(web): gzip response compression via flask-compress

The interface ships a ~5,000-line HTML shell and >20k lines of JS
uncompressed; on phone/WiFi that dominates load time. Flask-Compress
gzips/brotlis compressible responses transparently.

- Optional dependency, same graceful pattern as flask-limiter: missing
  package = uncompressed responses, no crash.
- SSE safety verified empirically against the real package (1.24): an
  actual streamed text/event-stream response comes back with no
  Content-Encoding while a large HTML response gzips — the display
  preview / stats / logs streams are unaffected.
- Added flask-compress>=1.14 to web_interface/requirements.txt.

* perf(web): gate verbose console logging behind the existing pluginDebug switch

plugins_manager.js, base.html's inline scripts, and app.js emitted 198
console.log calls in production - including per-interaction [DEBUG] dumps -
costing main-thread time and drowning real errors in noise.

- New window.debugLog() gate defined in base.html's first inline script
  (before any other script runs): forwards to console.log only when
  localStorage.pluginDebug === 'true' - the SAME switch plugins_manager.js
  already used for its _PLUGIN_DEBUG_EARLY logs, so existing debug workflow
  docs stay valid. Exposed as window.LEDMATRIX_DEBUG for other scripts.
- Mechanically rewrote console.log( -> debugLog( in plugins_manager.js
  (127), base.html (64), app.js (7). Verified no occurrences lived inside
  string literals before rewriting; console.error/console.warn untouched.
- app.js's no-Alpine showNotification fallback restored to console.info -
  it's a user-facing last resort, not debug output.

Both load paths are safe: the gate is the first inline <script> in <head>,
and every rewritten file loads deferred after it.

* perf(web): vendor CDN assets locally — LAN-speed loads, fully offline-capable

Font Awesome, CodeMirror, and htmx were fetched from cdnjs/unpkg on every
fresh page load, adding third-party round-trips on a device that often
lives on a local network (and htmx was local-only in AP mode, meaning two
different loading behaviors to reason about).

- Vendored pinned copies under static/v3/vendor/: Font Awesome 6.0.0
  (css/all.min.css + the 8 webfonts it references relatively) and
  CodeMirror 5.65.2 (core, javascript mode, closebrackets/matchbrackets
  addons, base + monokai css) - ~1.1 MB total, exact versions the CDN tags
  pinned.
- htmx + sse + json-enc extensions now load from the existing local copies
  (verified 1.9.10, matching the CDN pin) on EVERY network, not just AP
  mode; the pinned CDN copies remain as a one-shot rescue fallback,
  mirroring the pattern Alpine already used. The convoluted isAPMode
  source-flipping logic collapses away.
- Dropped the CDN preconnect/dns-prefetch hints (no longer on the critical
  path).
- Fixed a latent bug while relinking CodeMirror: the loader requested
  mode/json/json.min.js, which does not exist on cdnjs (HTTP 404 verified)
  - it 404'd on every JSON-editor open. JSON highlighting comes from the
  javascript mode; the phantom entry is removed.

* perf(web): extract 3,850 lines of inline JS from base.html to cacheable static files

base.html shipped ~4,200 lines of inline JavaScript inside the HTML
document, re-downloaded and re-parsed on every page load (gzip helps the
transfer, but inline scripts can never be browser-cached). The four
largest blocks - none containing any Jinja syntax, verified by scanning
every inline block for {{ }} / {% %} - now live as static files served
with the app's existing mtime-versioned immutable caching:

- js/htmx-config.js (246 lines): HTMX swap/script-execution config,
  toggleSection helpers
- js/app-early.js (346 lines): early helpers + the app() stub that must
  precede Alpine init
- js/app-shell.js (2,997 lines): SSE wiring + the full Alpine app()
  implementation and tab logic
- js/custom-feeds-helpers.js (262 lines): custom-feeds table helpers

Each replacement <script src> is CLASSIC (no defer/async) at the exact
position of the inline block it replaces - identical execution timing and
DOM visibility to inline scripts, so relative ordering with the deferred
scripts and with each other is unchanged. base.html drops from ~4,940 to
1,079 lines.

Validation: extraction proven lossless by programmatically reassembling
the four files back into the template and comparing against git HEAD -
byte-for-byte identical. Jinja parse passes; script open/close tags
balanced (53/53, after excluding a literal "<script>" inside an HTML
comment).

* fix(web): size the live preview from the PNG's real dimensions, not config

The initial SSE render sized the preview image (and both overlay canvases)
from the server-reported config dimensions (cols x chain_length,
rows x parallel), while the scale slider's re-render path sized from
img.naturalWidth/naturalHeight. Whenever the snapshot PNG's actual size
disagrees with the config (stale config, display service not restarted
after a hardware change), the initial render stretched the image at a
fractional ratio - blurry despite image-rendering: pixelated - and
touching the scale slider "fixed" it. Reported live on the devpi test rig.

Both paths now size from the loaded image's natural dimensions inside
img.onload (which also removes a transient wrong-size flash between
src assignment and load). The meta label now reports the true snapshot
size. The preview card also gets overflow-x-auto so on narrow screens a
wide preview scrolls at its exact pixel-perfect size instead of being
squeezed into the viewport (fractional downscaling of pixel art also
reads as blur).

* feat(web): fold Display Options into the advanced dropdown; Vegas above Double-Sided

Owner-requested layout refinement of the Display Settings tab:

- The "Display Options" card (disable_hardware_pulsing, inverse_colors,
  show_refresh_rate, use_short_date_format, Dynamic Duration) moves inside
  the collapsed advanced section, now titled "Advanced Hardware & Display
  Options (15)". Hidden form fields still submit with the form, and
  settings search still auto-expands the section on match, so nothing is
  lost - the tab just leads with the essentials.
- The "Vegas Scroll Mode" section moves above "Double-Sided Display".
  New section order: Hardware (+ advanced dropdown) > Vegas Scroll >
  Double-Sided > Multi-Display Sync.

Validation (real Jinja render): all 23 field names present exactly once,
divs balanced (70/70), the five Display Options fields render inside the
advanced section's bounds, and section markers confirm the new order.

* feat(web): Getting Started items are manually checkable; card auto-hides when complete

Two gaps reported from live testing on the devpi rig:

1. The timezone/location step never showed done for a user whose real
   timezone IS the shipped default (America/New_York) - the heuristic can
   only detect difference-from-default, not "user saved this". Clicking an
   item's checkbox now toggles it done manually (persisted per browser in
   localStorage), so any heuristic false-negative is one tap to clear.
   Clicking the item text still deep-links to its tab.
2. The card now hides itself automatically once every step is done
   (auto-detected or manually checked) - previously it stayed until the X
   was clicked.

* chore(web): CI cleanup — declare debugLog global, fix entity-unescape order, drop v3 from UI branding

- Add debugLog to the /* global */ headers of the six JS files that call it
  (defined in base.html's first inline script) — resolves the wall of
  "'debugLog' is not defined" ESLint errors failing the Codacy check.
- Fix the two js/double-escaping CodeQL alerts in app-shell.js: the
  entity-unescape chains decoded &amp; before &lt;/&gt;, so a value
  containing a pre-escaped "&amp;lt;" wrongly double-decoded to "<".
  &amp; now decodes last (standard order). Pre-existing bug, made visible
  when the inline scripts moved into scannable .js files.
- Page title / header drop the "- v3" suffix, matching the de-versioned
  user-facing URL.

The remaining 7 CodeQL alerts are pre-existing patterns newly visible to
scanning (CodeQL doesn't see inline template JS): 4 github.com/htmx.org
URL-substring checks (the htmx ones match error-message text, not URLs —
false positives in context) and 1 innerHTML XSS-through-DOM in the GitHub
install flow. Triage/fix deferred to a focused follow-up rather than
expanding this PR.

* fix(web): add the missing nav tab for the Rotation & Durations page

The durations partial (/partials/durations) has existed as a route with no
nav tab and no content panel referencing it - an orphaned page. That made
the new rotation-order UI unreachable through the interface (caught by the
owner testing on the rig; my endpoint-level tests fetched the partial by
URL and never noticed the missing entry point).

- New "Rotation" tab (fa-rotate icon, verified present in the vendored
  FA 6.0.0 css) between Display and Backup & Restore, wired exactly like
  the other tabs (#durations-content + hx-get + loadtab; loadTabContent()
  is fully generic, so no JS changes needed).
- Page heading updated from "Display Durations" to "Rotation & Durations"
  to match its content since the rotation-order card landed.

* fix(web): Rotation & Durations page lists every enabled plugin's screens

The durations grid looped over display.display_durations, which nothing has
ever populated (verified {} on a real production install) - so the page
rendered no duration fields at all. Worse, its inputs posted bare mode
names, which save_main_config's endswith('_duration') filter silently
dropped: the page was broken in both directions, unnoticed because it was
also unreachable (previous commit).

- pages_v3._load_durations_partial now builds one entry per display mode of
  every ENABLED plugin via plugin_manager.get_plugin_display_modes()
  (falling back to the plugin id), overlaid with saved values, defaulting
  to the display controller's 30s. Grouped per plugin, sorted by name.
  Saved keys not owned by any enabled plugin stay visible under "Other
  saved entries" instead of vanishing.
- durations.html renders the grouped inputs, named duration__<mode_key>
  (mode keys are arbitrary, so they can't use the *_duration suffix
  convention), with an explanatory empty state when no plugins are enabled.
- api_v3.save_main_config accepts the new duration__<mode> fields and
  writes them into display.display_durations under the bare mode key -
  exactly what the display controller reads
  (display_durations.get(mode_key, 30)).

Validation: py_compile both blueprints; Jinja render with 3 groups asserts
grouped inputs, saved-value overlay, stale-entry group, empty state, and
div balance.

Three usability improvements from live testing feedback:

- Restart-pending banner: every successful POST to /api/v3/config/main
  (display hardware, rotation/durations, general settings) now raises a
  persistent banner - "Configuration saved, restart the display to apply" -
  with a Restart Now button that posts restart_display_service directly.
  Backed by sessionStorage so it survives tab switches and reloads until
  restarted or dismissed. Plugin config saves are deliberately excluded:
  they apply live via the display process's config watcher.
- Unsaved-changes guard: plugin config panels are Alpine x-if templates,
  so navigating away destroys the panel and revisiting re-fetches it -
  edits were silently discarded. Forms now mark themselves dirty on input
  (cleared on successful submit), a capture-phase click handler confirms
  before a lossy tab switch, and beforeunload guards full page unloads.
  System tabs (x-show, persistent DOM) are exempt - no false prompts.
- Installable web app: manifest.json (standalone display, dark theme) +
  generated LED-grid icons (192/512 maskable + 180 apple-touch), linked
  from base.html. "Add to Home Screen" now yields an app-like fullscreen
  experience; no service worker, so zero behavioral risk.

* test(web): smoke tests + static-analysis audits for the web UI

Guardrails so this branch's fix classes can't regress silently:

- test_web_smoke.py (24 tests): boots the pages blueprint with the same
  dual registration app.py uses and asserts every page/partial returns 200
  with its load-bearing markers (nav wiring, getting-started card, advanced
  section, rotation order card, per-mode duration inputs), the /v3 legacy
  alias serves everything, all critical static assets (incl. vendored
  fontawesome/codemirror, PWA manifest/icons) are served, durations group
  per plugin with the leftover bucket, and the advanced-hardware section
  really contains the tuning fields. Would have caught this session's
  unreachable-durations-page and orphaned-tab bugs instantly.
- test_web_static_audit.py (3 tests): (1) every responsive utility class
  referenced in templates is actually defined in app.css - the
  silently-no-op class bug that left the header search box invisible at
  every width; (2) every url_for('static', ...) reference points to a real
  file; (3) any JS file calling the debugLog global declares it in a
  /* global */ header.

All 40 web tests pass (24 + 3 new, 13 existing) under pytest + Flask.

* feat(web): floating live preview + per-plugin "Preview on display", drawer a11y

Preview-while-configuring:
- Floating mini preview (fixed, bottom-right) available on every tab except
  Overview, fed from the same SSE display stream by updateDisplayPreview -
  no new connections. Collapses to a round toggle button; open/closed state
  persists in localStorage; hides on Overview where the full preview lives.
- "Preview on display" button on every plugin config page header: runs that
  plugin on the real display for 60 seconds via the existing
  /display/on-demand/start API and opens the floating preview, closing the
  configure -> see-the-result loop.

Drawer/nav accessibility:
- aria-current="page" tracks the active tab (system + dynamic plugin tabs,
  matched via their Alpine @click expression), updated from the activeTab
  watcher so search deep-links and checklist navigation are covered too.
- Escape closes the mobile drawer and returns focus to the hamburger;
  opening the drawer moves focus to its first tab.

Validation: all 40 web tests pass; Jinja parse + div balance on both
touched templates.

* fix(web): resolve Codacy findings — DOM building over innerHTML, Map callbacks, misc lint

Verified each of the 27 reported findings against current code; all fixed
except one rule class skipped with reason below.

- app-early.js: plugin tab buttons are now built with createElement/
  createTextNode instead of innerHTML template strings (icon class and name
  come from plugin manifests - semi-trusted input; the old code escaped the
  name but interpolated the icon class). Both construction sites. Also the
  forEach arrow no longer returns tab.remove()'s value.
- plugin-order-list.js: rows, empty state, and error state all built with
  DOM APIs - the file no longer contains innerHTML at all (the now-unneeded
  escapeHtml/escapeAttr helpers are removed); MODE_LABELS is a Map so the
  vegas-mode lookup can't hit prototype properties.
- notification.js: actionCallbacks is a Map (get/set/delete) instead of a
  plain object - resolves the object-injection-sink and dynamic-delete
  findings; triggerAction also type-checks the callback.
- htmx-config.js: unused catch binding dropped; var -> const in the
  afterSettle handler; the swapped-<script> re-execution reads/writes
  textContent instead of innerHTML; the diagnostic form payload uses a
  null-prototype object so a field named __proto__ can't pollute.
- custom-feeds-helpers.js DELETED (with its script tag): all three of its
  functions (addCustomFeedRow, removeCustomFeedRow,
  handleCustomFeedLogoUpload) are shadowed by the deferred
  widgets/custom-feeds.js window assignments, which always win at call time
  - the copies were dead even when they lived inline in base.html. This
  also resolves the unused-function and unused-variable findings there.

Skipped: 4x "Non-serializable expression must be wrapped with $(...)" in
app-early.js - that rule targets code crossing a browser-automation
serialization boundary (e.g. page.evaluate); these are ordinary arrow
functions in plain browser code with no such boundary.

Validation: all 40 web tests pass (incl. the static-asset reference audit,
which confirms no template still points at the deleted file); Jinja parse OK.

* feat(web): update flow installs changed Python dependencies automatically

The in-app updater (Update Now banner -> git_pull action) stashed, pulled,
and purged plugins - but never touched Python dependencies. Any release
adding a package (e.g. this branch's flask-compress, which lives in
web_interface/requirements.txt) silently required an SSH session and a
manual pip install that most users will never do.

- git_pull now records HEAD before pulling; after a successful pull it
  diffs old..new and, if requirements.txt or web_interface/requirements.txt
  changed, installs exactly those via _pip_install_requirements - the same
  vetted root-visible sudo path the Tools-tab buttons use (with its
  existing graceful fallback when the sudo wrapper isn't configured).
  Results are appended to the update toast; a failure points the user at
  the Tools-tab button instead of failing the whole update.
- install_base_requirements (Tools tab) now also installs
  web_interface/requirements.txt - previously it only covered the root
  file, so web-only dependencies were unreachable from the UI entirely.

No install happens when the pull was already-up-to-date or when no
requirements file changed, so routine updates stay fast.

* fix(web): address CodeRabbit review — validation, a11y, perf, and privacy fixes

Verified each finding against current code. Fixed:

- api_v3: plugin_rotation_order is now strictly validated (JSON list of
  strings, 400 with a descriptive message otherwise) and popped from the
  payload before any further handling.
- display_controller: _apply_plugin_rotation_order defensively ignores a
  non-list value (keeps the existing rotation, logs a warning) and drops
  non-string entries; new logs carry the [DisplayController] prefix.
  Unit-tested both defensive paths.
- app.py: snapshot-read handler narrowed to OSError with debug logging;
  flask-compress ImportError now emits one structured warning with the
  install remedy.
- htmx-config: the response-error logger prints form FIELD NAMES only -
  values (API keys, passwords) never reach the console.
- plugin-order-list: saved order/exclusions normalized with Array.isArray
  (a saved "null" previously crashed .forEach); each row gained
  keyboard/touch-accessible move-up/move-down buttons (HTML5 drag events
  don't fire on most mobile browsers) that reorder and syncInputs()
  immediately alongside native drag.
- app-shell: window.installedPlugins setter always takes the new list
  (same-ID metadata/enabled updates were silently dropped); tab rebuild
  stays gated on ID changes. LED dot renderer reads the frame with ONE
  getImageData call instead of one per pixel (~9,200/frame at 192x48).
- plugins_manager: togglePlugin returns its request promise resolving the
  API outcome; the install flow now shows the "installed and enabled"
  toast (with Restart Now) only after enablement succeeds, and a warning
  without a restart offer when it fails.
- a11y: hamburger aria-label flips Open/Close with drawer state; both
  Advanced-section toggle buttons declare aria-controls/aria-expanded and
  the shared toggleSection() keeps aria-expanded in sync; move buttons
  have per-plugin aria-labels.
- Rotation/Vegas order-list bootstraps cap their retries (~5s) and show a
  reload hint instead of spinning forever; Alpine app-state lookups prefer
  [x-data="app()"] with a generic fallback.

Skipped, with reasons:
- executePluginAction arg order: caller (plugin_config.html) already
  passes (actionId, index, pluginId) matching the signature exactly.
- generateFieldHtml XSS, entity-unescape blocks, dotToNested pollution,
  and "app.loadInstalledPlugins" in app-shell: all inside the legacy
  client-side config cluster whose entry points are shadowed by
  plugins_manager.js / replaced by server-rendered forms (zero live
  callers, verified) - queued for wholesale deletion in the follow-up
  rather than patching dead code.
- custom-feeds-helpers.js findings (3): file was deleted in a prior commit.
- console.error/warn override removal and afterSwap script re-execution
  removal: deliberate pre-existing workarounds every partial's inline
  init currently depends on; reworking them safely needs isolated testing
  (follow-up), and the error suppression is already double-gated
  (insertBefore AND htmx match).
- "move durations bootstrap into a bundle": inline partial-scoped init is
  the established pattern for HTMX partials in this codebase.

Validation: all 40 web tests pass; py_compile on all touched Python; all
touched templates parse; rotation-order defensive paths unit-tested.

* chore(web): fix remaining real Codacy findings (2 of 6)

- htmx-config.js: two more unused catch bindings dropped (optional catch
  binding), matching the earlier fix.
- app-early.js: second forEach arrow (the stub updatePluginTabs copy)
  braced so the callback no longer returns tab.remove()'s value.

The other 4 findings ("Non-serializable expression must be wrapped with
$(...)") are deliberately NOT "fixed": that rule belongs to a
browser-automation (WebdriverIO-style) lint context and is misfiring on
ordinary arrow-function constants. Converting them to function
declarations would look compliant but BREAK the code - all four arrows
intentionally capture the enclosing Alpine component's `this` for the
stub-to-full enhancement logic. The right remedy is disabling that
pattern for this repo in Codacy's Code Patterns settings (or dismissing
the four findings), not a code change.

* fix(web): floating preview shows a frame immediately on open + is resizable

The floating preview opened empty and stayed empty until the display next
CHANGED - the SSE stream only pushes frames on change, and the panel only
consumed frames while already open, so the connection's initial frame
(sent while the panel was closed) was dropped. Reported from mobile
testing as "the button doesn't work".

- updateDisplayPreview now caches the latest frame globally regardless of
  panel state; opening the panel populates the image from that cache
  instantly, then live frames take over.
- Resizable: a size button cycles 192/256/384/512px presets (persisted per
  browser; works on touch), and desktop additionally gets a native drag
  handle (CSS resize: both). The image is fluid within the panel; on
  phones the panel is capped to the viewport width. The size icon
  (fa-up-right-and-down-left-from-center) is verified present in the
  vendored FA 6.0.0.

* fix(web): stop duration fields leaking into config root; isolate per-file dependency installs; fix test fixture leak

Verified each finding against current code.

- api_v3 save_main_config: both duration blocks (*_duration suffix fields
  and the newer duration__<mode> fields) only READ from `data`, never
  removed the keys. The generic "remaining keys" merge later in the same
  function has no skip-list entry for either pattern, so every duration
  field was ALSO written a second time as a bogus top-level config key
  (e.g. "clock_duration": 30 and "duration__mlb_live": 42 sitting at
  config root, alongside the correct nested
  display.display_durations.<key>). Confirmed by tracing the full
  function. Fixed by popping each handled key from `data` (same pattern
  already used for plugin_rotation_order) and validating strictly: a
  non-integer duration now returns 400 with a message naming the
  offending field/mode instead of silently logging and moving on (for the
  *_duration fields, which previously had zero validation at all).
- api_v3 dependency-install loops (git_pull's post-update sync and
  install_base_requirements): _pip_install_requirements can raise
  subprocess.TimeoutExpired or OSError (confirmed: install_requirements_file
  in permission_utils.py never catches either internally, despite its
  docstring's "never raises on non-zero exit" only covering return codes).
  Both loops previously let one file's exception either abort the whole
  try block (skipping the second requirements file entirely) or propagate
  uncaught. Each file's install is now in its own try/except, so a timeout
  or OSError on one file is recorded as a labeled failure and the loop
  continues to the next file.
- test_web_smoke.py: the `client` fixture mutated the module-level
  pages_v3 Blueprint singleton's config_manager/plugin_manager directly
  with no teardown - since pages_v3 is shared across the whole pytest
  process (test_web_settings_ui.py touches the same attributes), this
  fixture's mocks could leak into whichever test ran next. Now saves the
  originals, yields the client, and restores them in a finally block.

Validation: py_compile passes; all 40 web tests pass with the now-generator
fixture.

* fix(web): repair garbled Advanced Hardware section description

An earlier sed-based text update concatenated the old and new copies of
this description instead of replacing one with the other, leaving a
duplicated sentence with the &mdash; entity broken into ".mdash;" (visible
as literal "mdash;" text on the page). Restored to one clean sentence.

Other findings from this review were already fixed in a prior commit
(installedPlugins setter) or are confirmed dead code with zero live
callers (executePluginAction/dotToNested/entity-unescape/generateFieldHtml,
all reachable only from the two unused savePluginConfig copies in
app-shell.js - grepped every template, no references) - same legacy
cluster flagged in earlier review passes, still queued for a dedicated
deletion follow-up rather than patched in place here.

* fix(web): remove redundant htmx:afterSwap script re-execution (was double-executing every partial's inline script)

Re-verified this CodeRabbit finding, previously deferred as "needs isolated
testing" - traced it to a confirmed, active bug rather than a style
concern:

htmx 1.9.10's own config defaults to allowScriptTags: true (confirmed in
the vendored htmx.min.js, which itself contains the same clone-and-reinsert
<script> mechanism internally). This means htmx ALREADY re-executes every
<script> tag in swapped content by default, exactly like a browser
navigating to a new page. The custom htmx:afterSwap listener in
htmx-config.js did the identical clone-and-reinsert a SECOND time on top of
htmx's own handling - so every inline <script> block in every HTMX-loaded
partial (overview, display, durations, plugin config, etc. - most partials
have one) executed twice per load.

Confirmed safe to delete outright, not just narrow: grepped every hand-written
JS file for a manual `dispatchEvent(... 'htmx:afterSwap' ...)` that might
have relied on this handler for a non-htmx code path (e.g. the direct-fetch
fallbacks like loadOverviewDirect) - none exists, so nothing depended on
this listener specifically; htmx's native handling covers every real
htmx-driven swap on its own.

Left in place, unchanged: the console.error/console.warn global override
a few lines up in the same file, which suppresses known-noisy
HTMX-timing-race messages. That one is a legitimate anti-pattern too
(broad substring matching can mask unrelated errors) but redesigning it
needs care to preserve real diagnostics while still hiding the specific
harmless races it targets - a scoped follow-up, not a same-day deletion
like this confirmed-duplicate handler.

Validation: all 27 fast web tests pass; JS brace/paren balance sanity
checked (no local Node/browser available in this sandbox to execute the
file directly - verify manually in-browser before merge).

* chore(display): add missing [DisplayController] prefix to the reconcile-complete log

Re-verifying the full CodeRabbit findings list against current code
surfaced one still-open item: the nitpick asked for the prefix on BOTH
rotation-related log lines, but only "Applied plugin rotation order" got
it in the earlier pass - "Plugin reconcile complete" was missed. No
message/argument/level change, matching the finding's own scope.

Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ

* fix(web): repair dead /v3/logs link on the display hardware-error banner

The "Logs tab" link in the display-settings simulation-mode banner was a
real <a href> to /v3/logs, but no such route has ever existed (log content
is loaded client-side via activeTab, not a dedicated page route) - the link
404'd regardless of the /v3 prefix change. Switch it to the same
activeTab-switching pattern the real nav uses.

* fix(web): raise display Rows field max from 64 to 128

Cols already allowed up to 128; Rows was capped at 64, which rejects
valid larger panel configurations (e.g. 128-row tile chains). No
server-side schema enforces a rows max, so this was purely an
overly-strict HTML input attribute.

* fix(web): remove redundant htmx.org substring check flagged by CodeQL

CodeQL flags .includes('htmx.org') as "incomplete URL substring
sanitization" - a false positive here, since this string is only ever
matched against console.error/warn message text to decide whether to
suppress a known-harmless HTMX timing-race log line, not used for any
URL-trust/redirect decision. The check was also redundant: 'htmx' is
already a substring of 'htmx.org', so the plain .includes('htmx') check
right next to it already covers every case the removed check did.

* fix(web): restore htmx script re-execution timing that Alpine x-data depends on

Removing the custom htmx:afterSwap script-reexecution handler (in a prior
commit, as a "duplicate execution" cleanup) broke every partial whose Alpine
x-data component function is defined by an inline <script> in that same
partial (e.g. wifi.html's wifiSetup()) - confirmed live via browser console:
"Alpine Expression Error: wifiSetup is not defined" on every field in the
WiFi tab.

Root cause: htmx's own native script execution runs during its "settle"
phase (~20ms after swap, per htmx's own defaultSettleDelay), but Alpine's
MutationObserver evaluates x-data on newly-inserted elements synchronously,
right as the swap lands - before settle. So the inline <script> defining
wifiSetup() was still un-run when Alpine tried to call it, and Alpine does
not retry a failed x-data evaluation later once the function does become
defined.

Fix: re-execute swapped <script> tags ourselves on htmx:afterSwap (which
fires synchronously, before settle, beating Alpine's observer), and disable
htmx's own native script re-execution (htmx.config.allowScriptTags = false)
so the same script doesn't also run a second time during settle - restoring
correct timing without reintroducing the original double-execution bug.

Also in this commit:
- fix XSS: unescaped repoUrl in a title attribute in renderSavedRepositories
- replace .includes('github.com') substring checks with real URL hostname
  validation (CodeQL: incomplete URL substring sanitization)

* fix(web): wait for async plugin install to finish before auto-enabling it

Confirmed live: installing hockey-scoreboard logged "installation queued"
(success) immediately followed by "enabling it failed" with a 404 "Plugin
not found" from /api/v3/plugins/toggle.

/api/v3/plugins/install runs the actual clone + plugin-manager discovery
asynchronously via an operation queue when one is configured - the response
installPlugin() was checking only means the operation was queued, not that
the plugin is installed yet. Calling togglePlugin() right after that
response 404s because plugin_manager hasn't discovered the new plugin.

Fix: reuse the same operation-polling mechanism uninstallPlugin() already
has (generalized pollOperationStatus() to take onComplete/onFailed/onTimeout
callbacks instead of hardcoding uninstall behavior) so installPlugin() waits
for the operation to actually complete before enabling it. Falls back to
enabling immediately when no operation_id is returned (direct/synchronous
install path, no queue configured).

* fix(web): resolve remaining valid findings from latest review pass

- custom-feeds.js: fix asset-upload contract mismatch (field name "file" ->
  "files", response read from top-level "uploaded_files" not "data.files") -
  same bug already fixed in this file on a separate branch/PR (#420), which
  this branch never received since they're independent PRs off main
- custom-feeds.js: add aria-label to the two icon-only "remove feed" buttons
- custom-feeds.js: move file-input reset into .finally() so a failed upload
  doesn't leave the input stuck holding the file, blocking retry of the
  same file
- app-shell.js: fix executePluginAction(pluginId, actionId) parameter
  order/count mismatch vs. its callers' (actionId, index, pluginId) -
  currently masked by plugins_manager.js's correct version overwriting this
  one at load time (classic vs. deferred script order), but worth fixing
  outright since it's an isolated, self-contained reassignment (not inside
  the Alpine app() object literal) and removes a latent footgun
- overview.html: align Alpine-state resolution with settings-search.js's
  two-tier getAppData() (also check appEl.__x.$data, not just _x_dataStack)

Verified already addressed by earlier passes (no change needed):
plugin_rotation_order validation, DisplayController log prefixes, togglePlugin
returning its promise for install-flow chaining, installedPlugins setter
always updating state, mobile-nav aria-label, toggleSection aria-expanded
sync, PluginOrderList bounded init retries (both display.html and
durations.html), plugin-order-list.js Array.isArray validation, batched
getImageData in the LED-dot preview renderer, app.py exception narrowing/
logging, form-submission log redaction.

Confirmed dead code, skipped (unreachable - zero template/JS callers,
verified via full-repo grep): dotToNested prototype-pollution hardening,
generateFieldHtml HTML-injection hardening, and the HTML-entity-unescape
block in JSON parsing - all three live only inside app-shell.js's two
legacy savePluginConfig implementations (one Alpine-method, one standalone),
neither of which any template or script calls. The real, live plugin-config
path is server-rendered via GET /partials/plugin-config/<id>.

Explicitly NOT reverted: the htmx:afterSwap script-execution listener. An
earlier finding batch asked to remove it as "duplicate" htmx behavior; that
was tried and reverted this session after live testing on hardware proved
it broke every partial whose Alpine x-data depends on an inline <script>
in the same partial (confirmed: WiFi tab hard-failed with "wifiSetup is not
defined"). Removing it again would reintroduce that regression.

66f9950a30 chore(ci): add security-audit tooling scripts (workflow files pushed separately) (#414)
* chore(ci): add security-audit workflow and plugin security-proof scripts

- scripts/prove_security.py, audit_plugins.py, generate_report.py --
  automated checks (dangerous eval()/exec() calls, dependency scanning,
  report generation) for plugins.
- .github/workflows/security-audit.yml + bandit.yaml -- CI wiring for
  the above plus gitleaks secret scanning and bandit static analysis.
- .github/workflows/tests.yml -- pytest matrix across Python 3.10-3.12.

Also fixes two Codacy findings while these files are freshly landing:
- prove_security.py: dropped a pointless f-string prefix with no
  placeholders.
- security-audit.yml: pinned gitleaks/gitleaks-action to a full commit
  SHA (matching this repo's existing pinning convention in test.yml)
  instead of the floating v2 tag.

Split out of the original chore/dead-code-removal commit, which had
accidentally bundled this in alongside unrelated dead-code deletions.

* chore: drop workflow files -- pushed separately (needs workflow OAuth scope)

* fix(security-tooling): address PR review findings across bandit.yaml, audit_plugins.py, generate_report.py, prove_security.py

bandit.yaml:
- Removed scripts/prove_security.py's file-level exclusion. Ran bandit
  directly to get ground truth: the real false positive is B105 (dict key
  "PASS" misread as password-like), not the eval/exec pattern the old
  comment claimed. Added a targeted # nosec B105 there, and found+fixed
  the identical pattern already present in generate_report.py.
- Left the repo-wide B607 skip as-is: confirmed via AST scan that properly
  narrowing it touches 100+ bare-name subprocess call sites across
  wifi_manager.py, store_manager.py, permission_utils.py, app.py, and
  start.py -- none of which are part of this PR. Out of proportion to fix
  here; flagged as a dedicated follow-up.

scripts/audit_plugins.py:
- SyntaxError/OSError while scanning a plugin file now report CRITICAL
  (blocking) instead of WARNING/INFO -- a file that couldn't be parsed or
  read was never actually checked for danger, so it must not silently
  pass the audit.
- --plugin <name> now tracks whether the requested plugin was found across
  all PLUGIN_BASE_DIRS and exits 1 with a clear error if not, instead of
  silently scanning zero plugins and reporting success.
- The AST visitor now tracks import aliases (import subprocess as sp;
  from builtins import eval as e) and resolves them before checking
  against dangerous APIs, closing a straightforward evasion of every
  PLUGIN-001 through PLUGIN-005 check. Verified against both aliased and
  unaliased evasion patterns.

scripts/generate_report.py:
- _md_table_row now escapes pipe characters and normalizes newlines in
  every cell, so scanner-controlled content (a matched secret, a bandit
  issue_text) can't corrupt the Markdown table structure.
- _load now distinguishes "artifact missing/malformed" from "valid empty
  result": each summarizer returns an availability flag, and main() now
  reports INCOMPLETE (not PASSED) with exit code 1 when any artifact is
  unavailable, instead of silently folding it in as 0 findings.
- Gitleaks suppression now uses exact-match placeholder values (pulled
  from the actual config_secrets.template.json) plus a template-path
  allowlist, replacing broad substring checks that could hide a real
  secret containing something like "example.com" as part of its value.

scripts/prove_security.py:
- T1b (dangerous plugin calls): a file that fails to parse/read now
  reports CRITICAL with the exception details instead of being silently
  swallowed by `except (SyntaxError, OSError): pass`.
- T6 (Docker hardening): base images must now be pinned to an @sha256
  digest; a specific tag like python:3.12 is mutable and is now correctly
  flagged as unpinned, not just missing tags or :latest.
- T2a (API surface): no config mechanism for enforcing local-only access
  exists in this codebase today (app.py hardcodes host='0.0.0.0'), so the
  "environment-aware" check as described isn't buildable without adding
  new config infrastructure -- out of scope here. Applied the achievable
  part: upgraded from INFO to WARNING, since enforcement can never
  currently be confirmed.
- T1a (zip-slip): replaced the whole-file substring check with an AST
  walk that finds every extract()/extractall() call and confirms an
  is_relative_to() guard + "Zip-slip detected" log precede it in the same
  function. Verified it still passes on the real store_manager.py (both
  the per-member and validate-then-bulk-extract call sites) and correctly
  flags a synthetic unguarded extractall().
- T3a (hardcoded secrets): violation details no longer include the
  matched credential text -- only file, line, pattern type, and a
  redacted SHA-256 fingerprint, so a real finding doesn't get published
  into CI logs/artifacts/PR comments with wider exposure than the
  original leak. Verified with a synthetic secret that no raw content
  reaches the output.

Validated: all four files compile; bandit scans all three scripts clean
(2 legitimate targeted suppressions, 0 unaddressed findings); each new/
changed code path exercised directly (alias evasion, unmatched --plugin,
missing/malformed/valid-empty artifacts, digest-pinning, zip-slip
guard/no-guard, secret redaction); full audit_plugins.py -> prove_security.py
-> generate_report.py pipeline run end-to-end producing a correct report.

* fix(security-tooling): address follow-up review findings on PR #414

scripts/generate_report.py:
- Added an explicit `object` type annotation to _md_sanitize_cell's value
  parameter -- it deliberately accepts any stringifiable value (calls
  str(value) unconditionally), so `object` reflects its actual contract
  more accurately than leaving it untyped.

scripts/prove_security.py:
- Dockerfile FROM-line parsing: renamed the comprehension variable `l` to
  `line` (ambiguous single-letter name). More importantly, fixed a real
  false-positive: `FROM --platform=<platform> <image>` was reading the
  --platform= flag itself as the image token, so a properly digest-pinned
  image behind a platform flag was incorrectly reported as unpinned.
  Verified against platform+digest, platform+tag-only, and digest+AS-alias
  Dockerfiles.

scripts/audit_plugins.py:
- Consolidated visit_Call's dangerous-API detection: previously, alias
  resolution only covered ast.Name calls for eval/exec/compile and
  ast.Attribute calls for subprocess/os.system, missing from-imported
  subprocess/os functions called as bare names (from subprocess import
  run as prun; prun(cmd, shell=True) or from os import system as s;
  s(cmd)). Added _resolve_call_target() to resolve both call shapes to a
  single fully-qualified target, then run all five PLUGIN-00x checks
  against that one resolved value. Verified against 10 evasion
  combinations (from-import aliases, direct/attribute calls, aliased
  module imports) and confirmed zero false positives on benign os/
  subprocess usage without shell=True.

Validated: all three files compile, bandit scans clean (same 2 legitimate
suppressions as before, 0 new findings), audit_plugins.py/prove_security.py
re-run against the real repo with no regressions from the prior fix pass.

4abcd0e4f9 Fix PermissionError reading config_secrets.json in web interface (#416)
ledmatrix.service (main display) runs as root while ledmatrix-web.service
runs as the non-root install user (install_web_service.sh). Both
config_manager.py and config_manager_atomic.py only chmod'd
config_secrets.json to 0o640 without ever fixing its group, so a file
written by the root service ended up group-owned by root and unreadable
by the web user, crashing the settings page with a raw PermissionError.

Add ensure_shared_group_ownership() to chgrp secrets/config files (best
effort, root-only) to the project directory's owning group whenever they
are created or saved, and self-heal existing files on load. Also make
get_raw_file_content() tolerate an unreadable secrets file the same way
load_config() already does, degrading to empty secrets instead of a 500.

2a1c47fa76 chore: remove dead modules and unused dependencies (~1,180 LOC) (#412)
* chore: remove dead modules and unused dependencies (~1,180 LOC)

Deletions, each re-verified with a fresh repo-wide grep (core, web,
scripts, docs, plugin monorepo) immediately before removal:

Modules with zero live importers:
- src/background_cache_mixin.py + src/generic_cache_mixin.py (134+150
  LOC — referenced only by each other)
- src/font_test_manager.py (134 LOC)
- src/image_utils.py (22 LOC, self-documented deprecated)
- src/layout_manager.py (408 LOC — only its own test imported it) +
  test/test_layout_manager.py
- src/common/basketball_plugin_example.py (328 LOC sample)

requirements.txt entries with zero importers in core (pre-plugin-era
manager deps): icalevents, geopy, timezonefinder, unidecode. Plus the
google-auth trio (google-auth-oauthlib, google-auth-httplib2,
google-api-python-client): their only importer is the calendar PLUGIN,
which declares all three in its own requirements.txt (verified in the
monorepo and on an installed copy) — the plugin dependency installer
owns them. Existing venvs are unaffected (removal doesn't uninstall);
fresh installs get them when calendar is installed.

Two stale references cleaned (a comment in test_pillow_compat.py, a
directory listing in HOW_TO_RUN_TESTS.md). Full suite green except the
two documented pre-existing failures (circuit_breaker mock drift, fixed
in #400; clock-simple 64x32 overflow, pre-dates this series); all core
entry modules verified importing cleanly under the emulator.

* fix: remove content accidentally bundled into the dead-code-removal commit

The previous commit's git add/commit swept in a lot of unrelated,
unreviewed work alongside the intended dead-code deletions: a new Plugin
Composer web UI, new security-audit/CI tooling, a new march-madness
plugin, and 23 local-development-only symlinks under plugin-repos/ (per
scripts/setup_plugin_repos.py's own docstring, these are meant to be
generated locally, never committed -- .gitignore has no entry for them,
which is how they slipped in).

Removed here, split into their own PRs instead (except plugin-repos/*
symlinks and march-madness/ncaa_logos, which are dropped rather than
carried forward -- see PR discussion):
- web_interface/blueprints/composer.py + composer-app.js +
  composer-canvas.js + composer.html + manager.py.j2
- scripts/prove_security.py, audit_plugins.py, generate_report.py
- .github/workflows/security-audit.yml, .github/workflows/tests.yml,
  bandit.yaml
- All plugin-repos/* symlinks (local dev artifacts, not meant to be
  committed at all)
- plugin-repos/march-madness/* and the 4 new assets/sports/ncaa_logos/*
  PNGs it needed (left out of every split PR pending a decision on
  whether march-madness belongs in the core repo or the plugin monorepo)

This PR now contains only what its title describes: the dead-code
removal from the previous commit, untouched.

14a59c863c perf(wifi): one status fetch per monitor tick instead of three (#411)
* perf(wifi): one status fetch per monitor tick instead of three

The wifi monitor daemon fetched WiFi status + ethernet state before its
AP-mode check, the check internally fetched the same state again (with
retry), and the daemon fetched a third time afterwards — each fetch is
several nmcli subprocess forks, every 30s, forever, even on a perfectly
healthy link.

check_and_manage_ap_mode's decision logic is extracted to
_manage_ap_mode(status, ethernet, ap_active); the new
check_and_manage_ap_mode_with_state() runs the single (retrying) fetch
battery and returns (changed, status, ethernet, ap_active_after) — the
post-state is derivable because state only ever flips via one enable or
one disable. The original bool-returning method delegates, so existing
callers are untouched. The daemon's dead pre-fetch is removed and its
post-check reads use the returned state; the AP-enable retry semantics
(_get_wifi_status_with_retry) are preserved exactly. ~10-15 forks/30s
drops to ~4-6.

- check_and_manage_ap_mode_with_state now declares its

- _manage_ap_mode's status/ethernet_connected/ap_active parameters are now
  typed (WiFiStatus, bool, bool), matching its existing -> bool return hint.
- test_wifi_check_state.py: rename unused unpacked variables (status/
  ethernet/ap_after) to underscore-prefixed names at the three call sites
  that don't use them, leaving the used ones untouched.

bff13129c4 perf(config): mtime-signature fast path for load_config (#410)
load_config re-read and re-parsed config.json, the secrets file, AND the
template (running the recursive migration diff) on every call — with
~30 call sites in web request handlers, some hit 2-3x per request.

Fast path: stat all three files (mtime_ns + size); when unchanged since
the last successful load, return the already-parsed self.config (same
aliasing semantics as before). The signature is taken AFTER load +
migration so a migration write-back doesn't retrigger, and both save
paths refresh it. Cross-process freshness is preserved by construction:
a save from the other process bumps the file mtime, so the next load
here re-reads — verified by a dedicated test. Same-second edits are
caught by mtime_ns plus a size check.

6499794c12 fix(testing): add MockCacheManager.get_cached_data_with_strategy/save_cache (#409)
* fix(testing): add MockCacheManager.get_cached_data_with_strategy/save_cache

ledmatrix-leaderboard's data_fetcher.py calls these two real-CacheManager
methods (src/cache_manager.py:313,817), but MockCacheManager had neither --
update() always hit an AttributeError, caught by a broad except and logged,
so the harness rendered an empty-but-green leaderboard on every test run
without ever exercising real standings data.

Both mocks delegate to the existing get()/set() -- a mock doesn't need the
real strategy's per-data-type max_age/market-hours timing, plugins under
test just need the methods to exist and round-trip whatever was cached.

* fix(testing): clear get_cached_data_with_strategy_calls in MockCacheManager.reset()

reset() cleared get_calls/set_calls/delete_calls but not the newer
get_cached_data_with_strategy_calls tracker, so a reused mock (e.g. across
test cases sharing a fixture) retained stale strategy-call records after
reset().

ChuckandGitHub 3d347a368a fix(testing): stop plugin enabled:false schema defaults from silently disabling harness tests (#408)
check_plugin.py, render_plugin.py, and the pytest plugin matrix each built
config as {"enabled": True} then merged in config_schema.json's defaults on
top, letting a plugin's own enabled:false default (a reasonable choice for
a seasonal/opt-in plugin -- 15 of 23 real plugins ship one) silently win.
Every harness/CI render of those plugins was testing "disabled, do
nothing" rather than real behavior.

Extract build_full_config() into testing/loading.py (already the shared
home for plugin-discovery/config-default logic) and use it from all three
call sites: schema defaults, then a forced enabled=True, then harness.json's
config, then the caller's explicit config -- so a test can still
deliberately disable a plugin on purpose, it just can't happen by accident
via the plugin's own shipped schema default anymore.

0aca40cf3a perf(plugins): run scheduled updates off the render thread (#407)
* perf(plugins): run scheduled updates off the render thread

plugin update() executed inline in the render loop — execute_update's
internal thread.join(timeout=30) blocked it, so one slow plugin HTTP
fetch froze scrolling for the whole fetch (up to 30s; DNS-retry storms
made this a regular occurrence on flaky networks).

Scheduling stays on the render thread and keeps every existing gate
(enabled, circuit breaker, can_execute, interval); due updates are now
enqueued to a single background worker (serialized — same one-at-a-time
execution as before, no thundering herd). RUNNING is set at enqueue so
can_execute blocks re-entry alongside the pending-set dedup.

Per-plugin locks make the old implicit update/display no-overlap
guarantee explicit: the worker holds the plugin's lock through its
update; the display side try-locks and, when the plugin is mid-update,
holds the last frame for that iteration — reported as success so a
mid-update skip never advances the rotation. Unlike before, the
guarantee now also holds across the post-timeout window (previously the
lingering update thread overlapped display()). Deadlock-free by
construction: the worker takes one lock; display never blocks.

Timeout semantics unchanged (lingering daemon thread documented).
Kill switch: plugin_system.synchronous_updates: true restores the
inline path.

8 new concurrency tests (non-blocking scheduler, overlap assertion
under a hammering display loop, lock release on failure/timeout paths,
dedup, kill switch); 4-min devpi soak clean (updates completing,
rotation advancing, no stuck RUNNING states).

* fix(plugins): fix skipped-frame health/force_change tracking, config validation, and lock-lifetime gaps in async updates

Addresses PR #407 review findings:
- display_controller: only clear force_change / record health success
  when display() actually ran this frame, not when the frame was skipped
  because the plugin's lock was busy (a skip must preserve a pending
  mode-switch force_clear).
- plugin_manager: replace bool() coercion of synchronous_updates with
  explicit isinstance validation of plugin_system/synchronous_updates,
  failing safe to synchronous mode (with a logged reason) on malformed
  config instead of silently defaulting to async.
- plugin_manager: _update_worker_loop now acquires the plugin lock before
  looking up its instance and re-checks under the lock, so an unloaded
  plugin's lifecycle state is never resurrected to ENABLED.
- plugin_manager + display_controller: move lock ownership (and, for
  updates, RUNNING/pending lifecycle bookkeeping) into the actual update()/
  display() call itself rather than the timeout-wrapped caller, so the
  lock stays held for the real operation's duration even after
  PluginExecutor's own join(timeout) elapses and a lingering daemon thread
  keeps running in the background.
- DisplayController.cleanup() now stops the update worker before tearing
  down display/cache resources; stop_update_worker() logs when the join
  times out instead of failing silently.
- test_async_plugin_updates: rewrite test_unloaded_while_queued_is_harmless
  to exercise the public unload_plugin() lifecycle (via a deterministic
  blocker) instead of deleting pm.plugins directly, and add a regression
  test proving the plugin lock stays held through PluginExecutor's own
  timeout while the real update() call is still running.

9837315308 perf(display): dirty tracking in update_display + plugin FPS declaration (#406)
* perf(display): dirty tracking in update_display + plugin FPS declaration

update_display now skips SetImage+SwapOnVSync when the frame is
byte-identical to the last pushed one (adler32 digest) AND brightness
is unchanged — brightness is part of the digest, and set_brightness
additionally resets it, so a dim-schedule change can never be skipped.
clear() resets the digest (it writes to the matrix directly). Skipping
a swap is hardware-safe: the panel refreshes the current frame from the
driver's own thread; swaps only change content.

Kill switch: display.dirty_tracking: false restores always-push.

display_controller's high-FPS decision gains a precedence step: a
plugin exposing needs_high_fps is honored first (so static-image can
declare False for still PNGs and stop burning a 125fps loop on them);
static-image without the attribute keeps its historical forced
high-FPS (GIF back-compat); scrolling logic is otherwise unchanged.

Verified with 7 tests against the real DisplayManager on
RGBMatrixEmulator (identical-frame skip, pixel-change push, clear and
brightness invalidation, snapshot-through-skip, kill switch) plus the
202-test display/controller/vegas suites, and a clean devpi deploy.
Audit: every SetImage/SwapOnVSync/Clear/brightness call site is inside
display_manager — no external writer can bypass the digest.

* fix(display): serialize update_display, narrow brightness exception, log fixes

CodeRabbit review on #406, verified against current code:

- update_display() can genuinely be called from background threads (some
  sports base classes call it directly from inside update() for an
  immediate "live" refresh), not just the render loop — confirmed via the
  existing follower-mode gating wrapper in display_controller.py, which
  exists specifically because "background plugin threads" can reach it.
  Without a lock, two callers could both pass the digest check before
  either writes _last_pushed_digest back, causing a redundant push, or
  interleave the offscreen/current canvas swap. Added self._update_lock
  (RLock, in case of re-entrant callers) around the full method body so
  every call site is automatically covered — no caller changes needed.
  (No prior lock existed to reuse on DisplayManager; this adds one.)
- Narrowed the brightness-read exception handler to AttributeError,
  matching the established pattern in get_brightness()/set_brightness()
  — a getattr() with a default already swallows AttributeError, so the
  only case this guards is the property getter itself raising, and the
  established pattern treats that as an expected, specific failure mode
  rather than something to blanket-catch.
- FPS-check debug log now includes the plugin_id already in scope
  (previously only active_mode) and a "[DisplayController]" prefix for
  grep-ability, matching the sibling log two lines below it.
- test_display_dirty_tracking.py: dm fixture and test_config_flag_wires_through
  now reset the DisplayManager singleton on teardown, matching the pattern
  test_display_manager.py already uses elsewhere in the same file family.
- test_snapshot_still_written_on_skip previously only exercised the
  non-skip (push) path despite its name; now performs a second update that
  meets the skip conditions (identical frame) and asserts the snapshot is
  still written even though the panel push itself is skipped.

All 7 dirty-tracking tests pass, plus the full display_manager/
display_controller/vegas suite (140 passed). Full repo suite has only the
5 known pre-existing failures (double-sided config x2, state_reconciliation
x2, and test_circuit_breaker's conftest.py mock signature drift — the
latter fixed in #400, which this branch's base predates).

c1fa5094be fix(store): plugin updates keep the old install until the new one succeeds (#405)
* fix(store): plugin updates keep the old install until the new one succeeds

Both reinstall paths in update_plugin — the monorepo-migration remote
switch AND the routine archive update every store user hits — deleted
the installed plugin directory BEFORE downloading its replacement. A
mid-update failure (bad network, registry error) permanently destroyed
the plugin. Seen in the field: a Pi with broken DNS lost 12 plugins in
one update pass during the monorepo migration.

New _reinstall_with_rollback: rename the old install aside (using the
'.standalone-backup-' name pattern plugin discovery already excludes),
run install_plugin, remove the aside on success — restore it on ANY
failure, clearing partial-download debris first. A stale aside from a
previous crash is cleared before starting.

* fix(store): serialize concurrent updates per plugin, check cleanup results

CodeRabbit review on #405 flagged two things in
_reinstall_with_rollback, both verified against current code:

- Real race: the web UI runs Flask with threaded=True and there's a
  single update route, so two overlapping requests for the same
  plugin_id (double-click, two tabs) can interleave. The loser could
  rename the winner's in-progress install aside mid-download, deleting
  its own rollback safety net — worse than the bug this function
  exists to fix. Added a lazy per-plugin_id lock dict (mirrors the
  plugin_manager per-plugin lock pattern) held for the whole function.
- _safe_remove_directory's return value was ignored at both call
  sites. Stale-aside cleanup failure now aborts cleanly instead of
  falling through to a rename that would fail anyway with a less
  useful error; post-success backup-removal failure now logs instead
  of failing silently (still returns True — the update itself
  succeeded, and the next update self-heals the leftover aside).

Left the third nitpick (test_stale_aside_from_previous_crash_is_cleared)
addressed by asserting the stale dir is actually gone and that
install_plugin was reached, rather than just the end-to-end result.

Added a concurrency regression test asserting install_plugin never
runs for the same plugin_id while another call is in flight.

4d49b0f892 perf(display): snapshot mirror — viewer gating, digest skip, keepalive (#404)
The display service PNG-encoded its frame to /tmp/led_matrix_preview.png
at 5 fps, 24/7 — identical frames, no viewers, per-call imports and a
chmod every write. On the devpi baseline the display service idles at
~92% CPU; this was one of its biggest fixed costs.

- New pure policy (src/common/snapshot_policy.py, unit-tested off-Pi):
  WRITE changed frames at full rate only while a viewer is watching,
  at a 30s idle cadence otherwise; NEVER re-encode unchanged frames —
  bump mtime (os.utime) every 20s instead, keeping the health check's
  snapshot-age liveness proxy (60s threshold in api_v3) green. Cross-
  referencing comments guard the two constants.
- Viewer detection: the web SSE display broadcaster (which only runs
  while browsers are subscribed) touches /tmp/led_matrix_preview_viewer
  each loop; the display service stats it at most 1/s. On viewer
  arrival the write clock resets so the first frame lands within ~1s.
- Hoisted the per-call pathlib/permission_utils imports; directory
  permissions ensured once instead of every frame.

Codacy (pylint access-member-before-definition) on #403: the throttled

273d9962d1 fix(cache): stop fsync-hammering the SD card on unchanged data (#402)
DiskCache.set wrote every key as mkstemp -> json.dump(indent=4) ->
flush+fsync -> replace -> chmod, on the persistent cache dir — dozens
of force-flushed SD writes per minute on an API-heavy install, mostly
rewriting identical data every plugin update cycle.

- Serialize once, compact (no indent): cache files are machine-read
  only; indenting multiplied the bytes written.
- Skip the disk when the payload for a key is unchanged (adler32 map,
  per-process); refresh the file mtime instead so records relying on
  mtime for TTL don't expire early. Self-heals if the file was removed
  externally (expiry cleanup).
- Drop the per-write fsync: os.replace already guarantees readers never
  see a torn file, and cache data is re-fetchable — the flush bought

9e3b5f366e fix(core): harden text-measurement caches; surface snapshot failures (#400)
* fix(core): harden text-measurement caches; surface snapshot failures

Deep-dive findings, all three latent on every 24/7 install:

- font_manager.metrics_cache and display_manager._text_width_cache were
  unbounded dicts keyed by (text, id(font)). Two problems: keys embed
  the measured TEXT, so ever-changing strings (a clock, a live score, a
  ticker) grow them without limit; and id()-keying without holding a
  reference means a garbage-collected font's id can be recycled by a
  DIFFERENT font, silently returning wrong widths/metrics (classic
  plugins create fonts per render, so this is reachable). Both caches
  are now LRU-bounded (1024) and pin the font in the entry so its id
  stays valid. metrics_cache also keyed on the text itself instead of
  hash(text), removing a collision path.

- _write_snapshot_if_due logged failures at DEBUG — invisible at the
  default level. The snapshot's mtime is the web UI's display mirror
  AND its hardware-liveness proxy, so a quiet failure freezes the
  mirror and makes health checks lie (seen in the field: a stale
  root-owned /tmp file froze it for a day). Failures now WARN, rate-
  limited to once per 5 minutes.

* test: sync mock cache manager signature with CacheManager.get

test_circuit_breaker has been failing on main: plugin_health passes
memory_ttl= to cache_manager.get(), and the conftest mock's signature
was never updated — the same component/double drift class as the
monitored_update bug (#392).

6edd80d9f3 fix(schedule): stop stray 'days' data from overriding Global schedule (#399)
save_schedule_config never persisted the schedule's 'mode' field, and
_check_schedule inferred per-day vs global purely from whether a 'days'
dict was present for the current day. Config migration
(_merge_template_defaults) re-adds the template's 'schedule.days' (all
days disabled by default) whenever it's missing from the user's saved
config - which is exactly the case after saving Global mode, since that
save path intentionally pops 'days'. The result: a user on Global mode
would get their schedule silently reinterpreted as per-day, with today's
day disabled, blanking the display.

Persist 'mode' on save and have _check_schedule honor it explicitly
(mirroring how _check_dim_schedule already does), so a resurrected
'days' dict can't override an explicit Global selection. Falls back to
the old inference behavior only when no 'mode' is recorded.

1c7a0cef66 fix(vegas): lock plugin_last_update snapshot/diff against concurrent mutation (#398)
* fix(vegas): restore live plugin-update refresh dropped by sync refactor

Investigating a user report that Vegas scroll mode doesn't update scores
or game status. Root cause: PR #299 (Mar 28) added a mechanism so a live
score change reached the ticker within a few seconds instead of waiting
for a full scroll cycle -- _tick_plugin_updates_for_vegas() diffed
plugin_last_update timestamps to detect which plugins got fresh data and
called coordinator.mark_plugin_updated() for each, and should_recompose()
checked has_pending_updates_for_visible_segments() to trigger an immediate
hot-swap.

PR #330 (May 14, multi-display wireless sync) refactored both call sites
while adding sync support and silently deleted this entire mechanism --
not just gated it behind the new sync-mode deferral it legitimately
needed, but removed it outright. The result: VegasModeCoordinator.
mark_plugin_updated() and StreamManager.has_pending_updates_for_visible_
segments() have been fully implemented but never called from anywhere
since. Vegas mode's only remaining freshness sources are a 5s content
cache TTL (fine) and full recompose at cycle boundaries, which depending
on min/max_cycle_duration can be minutes away -- so live scores/status
can sit stale far longer than a user would expect from a "live" ticker.

Fix:
- Restored _tick_plugin_updates_for_vegas() in display_controller.py,
  wired as the Vegas coordinator's update callback in place of the plain
  _tick_plugin_updates(). Diffs plugin_last_update before/after the tick
  and calls vegas_coordinator.mark_plugin_updated(plugin_id) for each
  plugin that actually got new data (rather than returning the list, since
  the callback interface no longer consumes a return value).
- Restored the has_pending_updates_for_visible_segments() check in
  render_pipeline.should_recompose(), positioned after (not instead of)
  the sync-mode early return PR #330 added, so standalone installations
  regain immediate refresh while synced leader/follower pairs correctly
  keep deferring hot-swaps to cycle boundaries as PR #330 intended.

Test plan:
- Added test_display_controller_vegas_tick.py and
  test_vegas_render_pipeline_recompose.py -- neither area had any prior
  test coverage, which is very likely why this regression went unnoticed
  for ~2.5 months.
- Verified both new test files fail against the pre-fix code (swapped in
  the current main versions of both files) with exactly the expected
  errors -- AttributeError for the deleted method, and the recompose
  assertion returning False instead of True -- then pass against the fix.
- Confirmed the sync-mode deferral this restoration must not break still
  holds: test_sync_active_defers_pending_updates_to_cycle_boundary.
- Full related suite (test_vegas_plugin_adapter, test_vegas_config,
  test_display_controller_plugin_toggle, test_display_controller_
  optimizations, test_plugin_system): 108 passed, 1 pre-existing failure
  unrelated to this change (test_circuit_breaker, stale mock signature).
- Full CI plugin-safety suite (test_harness, test_visual_rendering,
  test_plugin_matrix): 52 passed, 2 pre-existing skips.

* fix(vegas): lock plugin_last_update snapshot/diff against concurrent mutation

_tick_plugin_updates_for_vegas() snapshotted and later re-iterated
plugin_manager.plugin_last_update from the Vegas background update-tick
thread while the main render loop (or other callers) could mutate the
same dict concurrently — a real race (unprotected dict iteration/mutation
across threads), not just a style nit.

Move the snapshot/update/diff into a new locked
PluginManager.run_scheduled_updates_with_changes() so all reads and
mutations of plugin_last_update happen under one lock, and update
DisplayController to use it. The lock is only held around the dict
accesses, not the update pass itself, so slow plugin update() calls don't
serialize against other callers.

Also add a regression test covering that the Vegas coordinator is wired
to the Vegas-aware tick callback rather than the plain one.

Skipped as not worth the change:
- Narrowing the broad `except Exception` around
  vc.mark_plugin_updated(plugin_id) to specific types: it's a deliberate
  per-plugin isolation boundary (matches the same pattern used elsewhere
  in this file for plugin/coordinator calls) and there's no documented,
  stable set of exceptions that call can raise to narrow to.
- Adding an inactive-DisplaySyncManager test to
  test_vegas_render_pipeline_recompose.py: verified
  VegasModeCoordinator.set_sync_manager() already normalizes a
  SyncRole.STANDALONE manager to None before handing it to the render
  pipeline (src/vegas_mode/coordinator.py:152-156), so should_recompose()'s
  `is not None` check is correct in practice; the suggested case is
  already covered by that normalization.

7f7f0d6464 feat: adaptive layout system — size-aware regions, crisp font ladders, image fitting (#393)
* feat(layout): adaptive layout & font scaling system for plugins

Add src/adaptive_layout.py — opt-in core helpers so plugins render
legibly on any panel size without hand-tuned per-display layouts:

- Region: integer rect algebra (bands/columns/weighted splits/centering)
  that partitions space so text bands can't overlap by construction
- Font ladders: ordered (family, size) steps known to render crisply
  (LADDER_GRID: X11 BDFs at native sizes; LADDER_ARCADE: PressStart2P at
  8px multiples) — fitting walks the ladder instead of scaling pixel
  fonts fractionally
- LayoutContext: breakpoint tiers, geometry scale vs. a declared design
  size, and cached fit_text/fit_lines/font_for_rows queries

Generalizes the three patterns proven in the field: f1-scoreboard's
scale factor, masters-tournament's tiers, baseball-scoreboard's font
fallback ladder.

Wiring: BasePlugin gains a lazy .layout property and draw_fit();
FontManager gains get_native_bdf_size() and a cache_generation counter;
manifest schema gains display.design_size and requires.display_size
max_width/max_height; 96x48 joins DEFAULT_TEST_SIZES; the bounds-check
harness records negative-coordinate draws; TextHelper's broken
measurement helpers are fixed.

* feat(layout): adaptive image fitting + composite region helpers

Add src/adaptive_images.py — the image counterpart to fit_text:
- fit_image(img, box, mode=contain|cover|fill_height|stretch,
  crop_to_ink, anchor, resample, upscale) promoting the proven plugin
  patterns (football's crop-to-ink fill-height logos, masters' cover
  crop + NEAREST flags, static-image's letterbox). Upscales by default —
  thumbnail()'s downscale-only behavior is why imagery stays tiny on
  big panels.
- draw_fitted_image() pastes aligned within a Region with alpha mask.
- One central Pillow>=9.1 RESAMPLE shim replacing ~15 plugin copies.

LayoutContext.fit_image() caches results per (identity, box size,
options) with a 64-entry LRU; id()-keyed entries pin the source image.
BasePlugin.draw_image() is the one-liner adoption path beside draw_fit.

Composites in adaptive_layout.py: Region.offset() (user x/y-offset
passthrough), scoreboard_regions() (the two-logos-plus-score card math
duplicated across six sports plugins, logo_slot = min(H, W//2)), and
media_row() (art-left/text-right).

Fix LogoHelper's size-blind cache key (stale sizes on panel change);
deprecation note on dead image_utils.py.

* feat(harness): scale-up fill check, config variants, multi-size dev gallery

Quality gates for adaptive layout:

- fill_metrics()/check_scale_up() in the safety harness: overflow catches
  content too big for a panel, but nothing caught content that stays tiny
  on panels >= 2x the plugin's declared design size. The check measures
  lit-content extents and warns (or fails, when a plugin opts into
  "fill_check": "strict" in test/harness.json) below 50% coverage on the
  doubled axis. Warn-only by default so no existing plugin breaks.

- harness.json "variants": extra runs with config overlays and their own
  golden dirs, so an opt-in mode (e.g. layout_mode: adaptive) is golden-
  tested beside the classic default. check_plugin.py loops base + variants
  and labels variant results mode@name.

- Dev preview server: GET /api/sizes (harness size sample), POST
  /api/render-matrix (render at up to 12 sizes in one call), size-preset
  dropdown, and an "All Sizes" side-by-side gallery in the preview UI.

* feat(plugins): adaptive-lib discoverability + advisory version compat warning

Discoverability: re-export the adaptive layout/image API from src.common
(the blessed-helpers package plugin authors already know) — canonical
paths stay src.adaptive_layout / src.adaptive_images so nothing breaks.
Document it in src/common/README.md and cross-link ADAPTIVE_LAYOUT.md
from the developer docs authors actually read (quick reference, API
reference, advanced dev, font manager, dev preview, plugin dev guide);
ADAPTIVE_LAYOUT.md gains adaptive-images, composite-layouts and
preserving-user-customization sections.

Compat: PluginLoader now logs one advisory warning (never raises) when a
plugin's manifest declares a min LEDMatrix version newer than the running
core, checking the min_ledmatrix_version / requires.* / versions[]
spellings found in the wild. Guarded against stale core version numbers.

src/__init__.py __version__ bumped 1.0.0 -> 3.1.0 to match the latest
release tag (v3.1.0) — it had never been updated and the compat check
needs a truthful number. NOTE: verify this matches the intended release
numbering before the next tag.

* feat(layout): add measure_font_crispness — verify a ladder rung isn't blurry

PIL antialiases TTF outlines by default; a 'pixel-style' font only
rasterizes without antialiasing at specific sizes (for PressStart2P:
exact multiples of its 8px design grid). A ladder rung at an unverified
size silently renders blurry on an LED panel — this exact bug shipped in
both text-display's and football-scoreboard's custom TTF ladders
(non-8-multiple PressStart2P sizes, and '5by7.regular'/'4x6-font' at
sizes that were never actually crisp).

measure_font_crispness(font, sample_text) renders the sample and reports
the fraction of ink-bbox pixels that are neither pure black nor pure
white. BDF fonts (real bitmaps) always score 0.0; TTF ladders should be
verified against this before shipping — see the new
TestFontFitting::test_ladder_arcade_is_crisp pattern.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(layout): add fit_text_proportional — proportional sizing vs. always-maximize

fit_text always picks the largest ladder rung that fits its box. That's
right when an element owns dedicated space, but wrong when several
independently-fitted elements need to stay visually harmonious as the
panel grows: a score's box might have generous room while a neighboring
logo scales by a fixed geometry factor via px() — fit_text lets the score
balloon out of proportion (even overlapping the logo) even though its
individual pick is technically correct.

fit_text_proportional(text, box, base_size_px, ladder) instead targets
base_size_px * self.scale (the same scale factor px() already uses),
picking the nearest ladder rung at or below that target, still capped to
what fits the box, floored at the smallest rung when the target is below
every rung. Refactored the shared largest-that-fits/ellipsize walk into
_walk_ladder() so fit_text and fit_text_proportional don't duplicate it.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(layout): fit_text_proportional gains an axis-specific scale override

self.scale (min(width_ratio, height_ratio)) is the right conservative
default for anything whose aspect ratio matters, but a caller whose
surrounding composition already scales along a single axis — e.g.
football-scoreboard's logo_slot = min(height, width // 2), which tracks
height alone — needs text sized the same way, or it reads as
under-scaled next to logos that grew on a panel that only got taller
(128x32 -> 128x64: self.scale stays 1.0 since width didn't grow, but
logos still double).

fit_text_proportional(..., scale=None) now accepts an explicit override;
None keeps the existing self.scale default.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(layout): scoreboard_regions reserves real center space at 2:1 aspect ratios

logo_slot = min(height, width // 2) has a blind spot: at exactly 2:1
aspect ratio (width == 2 * height -- a very common shape: two, four, or
more square modules stacked into a taller panel) width // 2 and height
are equal, so the two logo slots claim the ENTIRE width and leave zero
pixels for a center column, no matter how large the panel gets. Not a
'small panel' problem -- 96x48, 128x64, and 256x128 (all exactly 2:1) hit
it identically, while the 128x32 design baseline and panels like 192x48
or 256x32 never do, because height is already the tighter constraint
there.

Two new parameters fix it in the one shared helper every scoreboard-style
plugin composes through:

- min_center_fraction / min_center_design_px reserve at least
  max(width * fraction, design_px * ctx.scale) for the center column,
  capping logo_slot further when needed. The scaled design-px term
  matters on small panels where a flat fraction alone reserves too little
  absolute space.
- score_bleed_fraction extends the score's own fit box (not the logo
  slots themselves) a controlled amount into each side -- the same way
  real broadcast scoreboards let a big score number's edges cross into
  the team marks flanking it. Without this the reserve alone can still be
  too narrow for a short score to render without truncating.

score_area is now genuinely narrower than the full card width (previously
identical to status_band/detail_band, which still span the full width and
overlay the logos -- short text there was never the problem).

Verified against the full harness size spread: a real game score like
'17-21' never needs ellipsis at any tested 2:1-or-tighter aspect ratio
(test_score_never_needs_ellipsis_for_a_short_score), and wide panels
(128x32/192x48/256x32-style) are provably unaffected.

- dev_server: broaden the render-request catch (a bad manifest.json now
  returns a clean 400 instead of an unhandled 500) and stop echoing raw
  exception text in the loader-failure responses — full tracebacks go to
  the dev server's console log instead.

CodeQL's barrier-guard recognition doesn't see a startswith check
inside an any() comprehension, so the normalize-and-prefix approach
still flagged. Break the taint outright instead: after lookup, re-derive
the directory by enumerating the search dirs (iterdir) and matching by
path equality — the Path used for all downstream file access is built
solely from trusted listings, never from request input.

Claude-Session: https://claude.ai/code/session_01FqzC1nzTWL4kaqgMaQZFam

* fix(dev-server): use os.scandir for path-injection barrier, redact stack traces from render responses

CodeQL doesn't model Path.iterdir() as a taint-clearing enumeration the
way it does os.scandir() -- _trusted_plugin_dir's iterdir-based rebuild
still traced plugin_id through to the manifest.json open(). Switched to
scandir, matching the pattern already verified clean on PR #396.

Also stops surfacing raw exception text (update()/display() failures)
in the JSON render response -- logs full detail server-side via
exc_info instead, returning only the exception class name to the
client. And drops path values from three plugin_loader debug/error
logs that CodeQL flags as clear-text-logging of externally-influenced
data, keeping plugin_id (not flagged) for context.

* fix(dev-server): remove conditional-reassignment ambiguity in plugin_dir resolution

CodeQL's path-injection flow still traced through _parse_render_request
after the scandir fix -- the tainted find_plugin_dir() result and the
scandir-derived _trusted_plugin_dir() result shared the same variable
name (plugin_dir), reassigned only on the truthy branch. That merge
point apparently isn't treated as a barrier by the flow analysis, so it
kept tracing the pre-reassignment value through to the manifest open().

Split into two distinct names -- candidate_dir (tainted, used only to
call _trusted_plugin_dir) and trusted_dir (the only name used for any
downstream file access) -- so there's no reassigned variable for the
flow to walk through.

* fix: remove unused imports flagged by Codacy

Union in adaptive_images.py and field in adaptive_layout.py are both
imported but never used -- the last two Codacy findings on this PR,
matching the same fix already applied on PR #396.

* fix(layout): bound the fit cache; never alias the source image in fits

Two latent issues found in a self-review pass:

- LayoutContext._fit_cache was an unbounded dict (the image cache got an
  LRU cap, the text-fit cache didn't). Cache keys embed the fitted TEXT,
  so a plugin fitting changing strings — a live game clock, a ticker —
  on a 24/7 service grows it forever. Now LRU-bounded at 512 entries via
  the same pattern as the image cache.

- fit_image returned the caller's ORIGINAL image object when the source
  was already RGBA at target size (contain/fill_height, no ink crop).
  ImageFitResult is documented as an independent copy, and LayoutContext
  caches results — an aliased image lets later mutations of the source
  corrupt cached fits (or vice versa). Copy in that branch.

Both covered by new regression tests.

05e7c43b27 fix(plugins): replace dependency marker files with a real satisfaction check (#390)
* fix(plugins): replace dependency marker files with a real satisfaction check

The .dependencies_installed hash-marker system only tracked "was this exact
requirements.txt hashed before" — not whether the packages it names are
actually present. That made it fragile (a wiped venv, a manually removed
package, or a lost/corrupted marker forces a needless full pip reinstall or,
worse, a false skip) and produced dead weight for the ~10 plugins whose
requirements.txt is comment-only (they still paid a pip subprocess on first
boot before a marker existed).

Replace it with requirements_are_satisfied() in plugin_loader.py, which
checks each real requirement line against importlib.metadata directly, so
install_dependencies() only shells out to pip when something is actually
missing or version-mismatched. Drops the marker file entirely: removed all
marker read/write sites in plugin_loader.py and store_manager.py, the
now-pointless marker-cleanup step in the git-update path, the unused legacy
marker implementation in plugin_manager.py, and the already-stale
clear_dependency_markers.sh script.

* fix(security): close path-injection gap in dependency-satisfaction checks

CodeQL flagged 2 new high-severity "uncontrolled data used in path
expression" alerts at the open() calls inside this PR's new
requirements_has_real_deps()/requirements_are_satisfied() -- both are
reachable from paths that were never run through the basename+trusted-base
sanitiser this codebase already uses elsewhere:

- PluginLoader.install_dependencies() only applied that sanitiser when its
  optional plugins_dir argument was actually passed; the "no plugins_dir"
  branch trusted plugin_dir_real directly. Made plugins_dir required (not
  Optional) so that branch can't exist, and added an explicit guard in
  load_plugin() so install_deps=True without a plugins_dir fails loudly
  instead of silently. Production's only real caller (PluginManager) always
  passes plugins_dir already; the harness/dev-server/render-plugin callers
  all use install_deps=False and are unaffected.

- StoreManager._install_dependencies() never sanitised plugin_path at all,
  and its call sites ultimately derive that path from a plugin's own
  manifest.json "id" field (install_plugin_from_url) -- a malicious plugin
  could otherwise point requirements_file outside plugins_dir. Applied the
  same os.path.basename()-based containment pattern PluginLoader already
  uses (and that CodeQL recognises as a real sanitiser).

Added test_install_dependencies_requires_plugins_dir and
test_install_dependencies_rejects_path_outside_plugins_dir to lock in the
actual security property, not just quiet the scanner. Verified: all 20
tests in test_plugin_loader.py pass, plus the PR's existing test plan
(test_plugin_system.py, test_store_manager_caches.py: 53 passed) and the
full CI plugin-safety suite (test_harness.py, test_visual_rendering.py,
test_plugin_matrix.py: 52 passed, 2 pre-existing skips) all still pass.

* fix(security): replace basename-only sanitiser with a trusted-enumeration check

The previous commit's os.path.basename() + os.path.join() pattern (which a
pre-existing code comment claimed CodeQL recognises as a sanitiser) did not
actually clear the alert -- the next CodeQL run still flagged the same 2
sink lines, plus a new one at the os.path.join() call itself. Taking a
substring of tainted data apparently isn't treated as a barrier by this
query, whatever the comment assumed.

Replaced it with find_trusted_subdir(): enumerate the trusted plugins_dir
via os.scandir() and only use a name that scandir itself produced, matched
by equality against the caller's requested name. The path is then built
from that enumerated entry, not from the caller's string -- a value
sourced from iterating a trusted, non-tainted directory carries no taint
regardless of what it happens to equal, which is a stronger and more
conventional allowlist-style barrier than string-stripping. Applied
identically in both PluginLoader.install_dependencies() and
StoreManager._install_dependencies(), sharing one implementation.

Re-verified: all 65 tests across test_plugin_loader.py (20, including the
2 new security regression tests), test_store_manager_caches.py (35),
test_plugin_system.py (10) pass, plus the full CI plugin-safety suite
(test_harness.py/test_visual_rendering.py/test_plugin_matrix.py: 52
passed, 2 pre-existing skips).

* fix(security): redact URL credentials from pip subprocess output before logging

CodeQL flagged 3 clear-text-logging-of-secrets alerts in
install_requirements_file() (src/common/permission_utils.py:353,360,371).
Pre-existing on main, unrelated to this PR's own diff, but now visible
since the path-injection alerts that previously took priority in the
annotation list are fixed.

The underlying risk is real: pip can echo a private index URL's embedded
basic-auth credentials (from a requirements.txt --index-url line or
PIP_INDEX_URL) back verbatim in its own stderr/stdout on failure, and this
function both logs that output directly and returns it to callers --
store_manager.py's _install_dependencies() logs result.stderr from this
same function too.

Added _redact_url_credentials(), applied immediately after each of the two
subprocess.run() calls (mutating result.stderr/stdout in place) rather
than patching each log call site individually. This closes the leak at
the source: every downstream use -- the three flagged log lines, the
"note" string embedded in the returned stdout, and store_manager.py's own
logging of the returned result -- gets the redacted text for free.

Verified the fixed-phrase "denied" check (`"a password is required" in
result.stderr`) is unaffected, since URL syntax and those phrases don't
overlap -- covered explicitly by
test_does_not_touch_denied_check_phrases. Added
test/test_permission_utils.py (6 tests) covering the redaction helper
directly and both subprocess.run() call sites (the sudo-wrapper branch,
which this repo's scripts/fix_perms/safe_pip_install.sh makes live, and
the no-wrapper fallback branch). All pass.

* fix(security): stop interpolating req_file/pip-output into log calls

The previous commit's redaction (mutating result.stderr/stdout right after
each subprocess.run()) didn't clear CodeQL's clear-text-logging alerts --
same lesson as the path-injection fix earlier in this PR: a static
analyzer can't tell "this value was already sanitised two lines up" from
"this is still the raw tainted value" just by looking at a single log
call in isolation, so it conservatively keeps flagging it regardless of
what the redaction function actually does.

Removed all dynamic interpolation (req_file, result.stderr) from the 3
flagged logger.warning() calls entirely, replacing them with fixed
messages plus (for the one that had it) result.returncode, which is a
plain int with no possible taint. The full redacted detail is still
available where it actually matters -- in the returned
CompletedProcess.stderr/stdout and the "note" text -- just not duplicated
into a log line a scanner has to reason about in isolation.

Re-verified: all 6 test_permission_utils.py tests still pass (they assert
on the returned result, not log call arguments), plus the full
test_plugin_loader.py/test_store_manager_caches.py/test_plugin_system.py
suite (71 passed, 1 pre-existing deselect, 4 subtests).

ChuckandGitHub 2ffc57cf40 fix(plugin-harness): add no-op process_deferred_updates to test double (#391)
The safety harness's VisualTestDisplayManager (base of
BoundsCheckingDisplayManager) doesn't implement process_deferred_updates(),
which 5 first-party ledmatrix-plugins call unconditionally between
set_scrolling_state() and their scroll-position update: news, odds-ticker,
ledmatrix-leaderboard, stock-news, and ledmatrix-stocks. Any of them fails
the harness with AttributeError the moment it's touched (surfaced when
ledmatrix-plugins#177 had to add a local hasattr guard in ledmatrix-stocks
just to pass CI). Add the method as a no-op, mirroring the existing
"no-op for testing" pattern already used for set_scrolling_state, so these
plugins render under the harness without every touching PR needing its own
guard.
2026-07-11 08:55:03 -04:00
ChuckandGitHub aab0e9ade0 fix(plugin-manager): fix TypeError breaking every plugin's scheduled update (#392)
run_scheduled_updates()'s resource-monitor branch wrapped the update call
in a closure stored as a *class* attribute on a dynamically-built type
(type('obj', (object,), {'update': monitored_update})()). The descriptor
protocol turns a function found via class-attribute lookup into a bound
method on instance access, silently prepending the synthetic instance as
an implicit first argument -- but monitored_update() takes none, so every
call raised "monitored_update() takes 0 positional arguments but 1 was
given", was caught by run_scheduled_updates' try/except, and recorded as
an update failure.

self.resource_monitor is None by default and was dormant until PR #388
("activate dormant plugin health/metrics subsystem") wired it up in both
display_controller.py and web_interface/app.py -- meaning this bug went
live in every real deployment as of that merge (2026-07-09) despite the
buggy line itself dating back to 2025-12-27. In practice this means no
plugin's update() has succeeded since upgrading past #388: circuit
breakers cycle through half-open -> immediate failure -> reopened every
health-check interval forever, and all plugin data (scores, odds, prices,
etc.) goes stale from whatever was last fetched before the upgrade.
Confirmed live on a running instance: odds-ticker (and stock-news,
ledmatrix-stocks, baseball-scoreboard, ledmatrix-leaderboard, of-the-day)
failing this exact way every 5-minute circuit-breaker retry.

Fixed by using types.SimpleNamespace(update=monitored_update) instead of
a dynamic class: SimpleNamespace stores attributes on the instance
itself, so attribute lookup returns the plain function unchanged --
never routed through the class-attribute descriptor protocol that
injects an implicit self.

Added test_run_scheduled_updates_calls_update_with_resource_monitor to
test/test_plugin_system.py using a real PluginResourceMonitor (not a
mock of it), so the test exercises the actual descriptor-binding
behavior that caused this. Verified the test fails with the exact
reported error against the pre-fix code and passes against the fix.

978a03b42d Add settings tooltips and search to the web UI (#387)
* Add settings tooltips and search to the web UI

Help users quickly find settings and understand how each one works.

Tooltips: a new delegated controller (static/v3/js/tooltips.js) drives an
accessible (i) info tooltip that appears on hover, keyboard focus, and tap.
A shared `help_tip` Jinja macro (partials/_macros.html) emits the trigger;
the plugin config macro and the core settings partials now surface help
text through it. Per the design, the always-visible field help paragraphs
are folded into the tooltip to declutter the forms, and the hardware/display
settings carry authored detail (default, range, recommendation).

Search: a global header search box finds settings across every settings tab
— even ones not yet opened — via a lazy client-side index built by scanning
the same field markup (static/v3/js/settings-search.js). Selecting a result
switches tabs, waits for the field to load, then scrolls to and flashes it.
A per-tab filter box hides non-matching fields on the current tab.

Plugin settings get tooltips for free by reusing each field's schema
`description`; every settings field also gets a stable `setting-<tab>-<key>`
anchor id for search navigation.

Styling uses the existing --color-* theme vars so light/dark mode both work,
and honors prefers-reduced-motion. Adds Flask render smoke tests that assert
each settings partial ships tooltips, anchors, and a filter box.

* Address Codacy static-analysis findings in settings JS

Refactor the two new modules to clear the flagged patterns without any
behavior change:

- Build the search dropdown with DOM nodes + textContent instead of
  innerHTML string concatenation, removing the XSS sinks and the manual
  escapeHtml helper it needed.
- Replace numeric index access (index[i], terms[j], opts[idx],
  currentResults[i]) with array iteration methods, NodeList.item(), and
  Array.prototype.at() to clear detect-object-injection.
- Use === via a shared termsMatch() helper, optional-catch binding, and
  drop a useless initial assignment.

Verified with ESLint (eslint:recommended + eslint-plugin-security) at zero
findings and re-ran the headless-Chromium behavior test (tooltip, per-tab
filter, global search navigation) — all green.

below the cyclomatic-complexity threshold. No behavior change; verified with
the headless-Chromium test.

* Resolve remaining Codacy findings in settings search

- Validate plugin ids against a strict allowlist (mirroring the server's
  _SAFE_PLUGIN_ID_RE) before they can appear in a fetch path, so the request
  URL is never built from unvalidated input (Codacy: user-controlled URL).
- Document that the fetched HTML is parsed into an inert document (scripts
  never run, never inserted into the live DOM) purely to read field text for
  the search index.
- Declare block-scoped locals with const instead of var where they were
  nested inside conditionals (Codacy: var not at function root).

No behavior change; re-verified with ESLint and the headless-Chromium test.

* Serve the settings search index from the server as JSON

Move index building off the client so there is no client-side HTML fetching
or DOM parsing (resolves Codacy's variable-fetch and DOMParser flags on the
read-only, same-origin index build).

- Add GET /v3/settings/search-index (pages_v3.py): renders the settings
  partials server-side and extracts each field's anchor id, key, label,
  tooltip, and section with a small stdlib HTMLParser, then caches the result
  keyed on the installed-plugin set. Parsing the rendered HTML keeps anchor
  ids identical to the live DOM, so the index cannot drift.
- settings-search.js: buildIndex() now does a single fetch of the literal
  endpoint + .json(); removed the per-partial fetch loop, DOMParser, scanDoc,
  CORE_TABS, and the plugin-id allowlist. Search, keyboard nav, navigation,
  and the per-tab filter are unchanged.

Net: fewer requests and no client-side HTML parsing. Verified with a new
endpoint test in test_web_settings_ui.py (12 pass) and the headless-Chromium
test (tooltip, filter, search navigate + flash all green).

- pages_v3: include Durations tab in the search index so
  setting-durations-* fields are actually indexed
- test_web_settings_ui: assert setting-durations-clock is present in
  the search-index endpoint response
- settings-search.js: on index fetch failure, reset buildPromise
  instead of caching an empty (truthy) index so search can retry
- settings-search.js: filterScope returns null (not document) when no
  tab container matches, and the caller guards, so the per-tab filter
  can't hide fields across unrelated tabs
- settings-search.js: refresh the stale header comment to describe the
  server-side JSON index flow
- app.css: cap #settings-search-results height with overflow-y so the
  dropdown scrolls instead of overflowing small screens

* Fix stuck search dropdown; add plugin-tab nested-settings filter

Global search:
- Close the results dropdown on input blur (guarded, with a short delay)
  so it reliably dismisses when focus leaves — previously it could linger
  because the only outside-close was a document click that Alpine/HTMX
  handlers can swallow.
- Clear the query text after navigating to a result so refocusing the box
  doesn't re-open stale results.
- Also dismiss on htmx:afterSwap (tab changes / navigation).

Per-tab filter (now on plugin tabs too):
- Render the shared settings_filter box in the plugin Configuration panel.
  It auto-wires: the delegated input handler and filterScope already target
  .plugin-config-tab.
- Teach applyTabFilter to reveal matches inside collapsed nested sections
  (render_nested_section defaults them shut), hide nested-section wrappers
  with no matches, and restore the original collapsed layout when cleared
  (only re-collapsing sections the filter itself opened).
- Count a visible nested-section as content for its parent heading so the
  heading isn't hidden while a subsection below still has matches.

Adds a plugin-config render test (filter box + nested anchors + tooltips).

Claude-Session: https://claude.ai/code/session_014gZxznuxw8L92FUMBN3Nqz

* Close search dropdown via capture-phase outside-click

The dropdown could stay open after clicking away because the only
outside-click close was a bubble-phase document listener. The v3 UI is
one Alpine app() component full of HTMX/Alpine/widget click handlers;
when a click lands inside an element that calls stopPropagation(), the
event never bubbles to document and the close never runs.

- Replace the bubble-phase document 'click' close with a capture-phase
  'pointerdown' listener scoped to #settings-search-wrap. Capture runs
  before any bubbling stopPropagation can swallow the event, so it always
  fires; pointerdown also covers touch on the Pi screen. Clicking a result
  stays inside the wrap, so selection is unaffected.
- Guard the debounced input handler so a delayed render can't re-open the
  box after focus has left (type-then-click-away race).

Keeps the existing blur / Escape / htmx:afterSwap closes as secondary paths.

* Fix settings search dropdown not visually closing

.hidden has no effect in this app: app.css is a hand-picked utility
subset (no Tailwind build step) and never defines .hidden { display:
none }. openResults()/closeResults() only toggled the class, so the
dropdown stayed rendered (display: block) even once closeResults()
ran - confirmed via computed style in a headless browser. Set
style.display directly, matching the fallback already used by
revealNode()/collapseNode() elsewhere in this file.

bd9f461f70 Add system diagnostics, power controls, and WiFi radio toggle to Tools tab (#389)
* Add system diagnostics, power controls, and WiFi radio toggle to Tools tab

Expands the web UI Tools tab with safe, purpose-built controls so users can
manage the Pi without SSHing in, instead of an arbitrary-command terminal
(the web UI has no auth and CSRF is disabled, so a shell would be unsafe).

- System Diagnostics card: renders the existing but previously-unused
  GET /api/v3/system/status endpoint (CPU, memory, temp, disk, uptime),
  with a manual refresh and a 10s poll.
- System Power section: reboot/shutdown buttons wired to the existing
  reboot_system / shutdown_system actions, behind a confirm step, with a
  dedicated powerAction() helper that treats the dropped connection as the
  expected "going offline" outcome rather than an error.
- Network Radio section: WiFi on/off toggle backed by new
  GET/POST /api/v3/wifi/radio endpoints and WiFiManager.set_wifi_radio() /
  get_wifi_radio_state(). Disabling WiFi is refused unless a wired
  connection is present (reusing the existing lockout guards), with an
  explicit force-off confirmation for advanced users.

No new privileged commands: uses nmcli radio wifi on|off (already
sudo-allowlisted) and the existing reboot/poweroff grants, so the
sudoers-alignment guard test stays green. Bluetooth toggle intentionally
omitted since the installer removes the BlueZ stack for LED timing.

Claude-Session: https://claude.ai/code/session_019X3he87Ggr1qt8y7mnFeuE

* Harden WiFi radio endpoint and diagnostics poll (review feedback)

Addresses code review feedback on the Tools tab additions:

- api_v3.py: parse the `enabled` POST field with the same string-aware
  coercion as `force`. A plain bool() cast turned {"enabled":"false"} into
  True (enabling instead of disabling) for any non-UI API caller.
- wifi_manager.set_wifi_radio() now returns a reason code alongside
  (success, message); the /wifi/radio error response includes it. The Tools
  UI only shows the force-off confirmation when reason == 'no_ethernet', so a
  genuine nmcli failure surfaces its real error instead of a misleading
  "no wired connection" prompt that would just retry into the same failure.
- tools.html: gate the 10s diagnostics poll on panel visibility
  (document.hidden / offsetParent), so switching to another tab stops the
  recurring /api/v3/system/status calls instead of churning the Pi off-screen.
  The initial load and manual Refresh remain unconditional.

Verified: {"enabled":"false"} now disables (refused w/ reason:no_ethernet),
{"enabled":"true"} enables; inline JS passes node --check; py_compile clean.

* Narrow WiFi-disable fallback except and add stack trace (review)

Addresses a CodeRabbit nitpick: the fallback handler in set_wifi_radio()'s
disable path caught bare Exception and logged without a traceback. Narrow it to
(OSError, subprocess.SubprocessError) — the errors subprocess.run realistically
raises — and log with exc_info=True for full context on the Pi. Anything
genuinely unexpected now propagates to the endpoint's outer handler (500),
matching the codebase's specific-exception convention.

3b93024993 feat: activate dormant plugin health/metrics subsystem and surface it in the web UI (#388)
* feat(plugin-system): activate dormant plugin health & metrics subsystem

PluginManager shipped a fully-built health tracker, resource monitor and
circuit breaker that were never instantiated (health_tracker/resource_monitor
were left as None), so the circuit breaker never engaged and the existing
health/metrics API routes always returned "not available".

- DisplayController now wires a PluginHealthTracker and PluginResourceMonitor
  onto the plugin manager, enabling the circuit breaker (a repeatedly-failing
  plugin's update() is skipped after consecutive failures, then retried after
  a cooldown) and per-plugin execution-time metrics. Both persist to the
  shared cache.
- load_plugin() now validates each plugin's config against its JSON schema in
  a strictly warn/degrade-only way: a violation logs a warning and flags the
  plugin degraded in the health tracker, but never changes whether the plugin
  loads or its pass/fail behaviour. Adds PluginHealthTracker.set_degraded(),
  which never touches the circuit breaker.
- ResourceMonitor CPU/memory sampling now reuses a cached psutil.Process and
  reads cpu_percent(interval=None), so monitoring no longer blocks ~100ms per
  call on the display loop's update path.
- Fix DiskCache.get() raising TypeError for max_age=None ("never expires"),
  which silently discarded persisted plugin health/metrics on read and thus
  broke cross-process and post-restart surfacing.
- Fix two dead PluginManager helpers that called non-existent tracker methods.

Tests: new test_resource_monitor, test_plugin_health,
test_plugin_manager_schema_soft; extended test_cache_manager and
test_display_controller.

* feat(web-ui): surface plugin health, metrics and load state

With the health/metrics subsystem now active in the display service, expose it
in the web UI (which runs as a separate process from the display loop):

- Wire a health tracker / resource monitor backed by the shared on-disk cache
  into the web process so /api/v3/plugins/health and /plugins/metrics read the
  data the display service persists.
- Build those route responses per installed plugin id (the tracker's in-memory
  view is empty in a fresh web process) so cross-process data is included.
- Add state + error_info to /plugins/installed entries so the UI can show why a
  plugin isn't running instead of just loaded:false.
- Add a "Plugin Health" panel to the Tools page (circuit status, avg/max update
  time, update count, last error) plus PluginAPI.getPluginMetrics().

Tests: route-level tests for the health/metrics endpoints in test_web_api.

* fix(plugin-metrics): refresh cross-process health/metrics reads; type hints

Addresses CodeRabbit review on #388:

- Major: the web process's health/resource trackers cached the first persisted
  read in an in-memory dict (and the CacheManager memory tier held max_age=None
  entries indefinitely), so a long-lived web process showed the first snapshot
  and never reflected the display service's later updates. Add an opt-in
  force_reload path (get_health_summary/get_health_state/_load_health_state and
  get_metrics_summary/get_metrics) that bypasses the in-memory copy and, via a
  new memory_ttl passthrough on CacheManager.get, the cache manager's memory
  tier — so each /plugins/health and /plugins/metrics poll reads fresh persisted
  state. Default behaviour (force_reload=False) is unchanged for the display
  process and existing callers.
- Minor: DiskCache.get type hint is now Optional[int] with the None ("never
  expires") semantics documented, matching MemoryCache.get.

Tests: new force_reload staleness cases in test_plugin_health and
test_resource_monitor.

85d321cf33 fix: plugin_loader retries with --ignore-installed on apt/pip RECORD conflicts (#386)
* fix: plugin_loader retries with --ignore-installed before assuming apt package satisfies pin

install_dependencies treated any "uninstall-no-record-file" pip failure as
"dependency satisfied" and wrote the success marker without ever attempting
--ignore-installed, unlike install_dependencies_apt.py and
safe_pip_install.sh (added in #385 for the Plugin Store/first-time-install
paths). A plugin pinning a newer version of a system-managed package (e.g.
requests) would silently keep running against whatever version apt shipped,
while the marker file claimed the pinned requirement was met.

Now retries the same install with --ignore-installed on that specific
failure so pip actually lays the pinned version down (shadowing the
system-managed copy) before falling back to the prior tolerant behavior if
the retry itself fails too.

* chore: suppress Codacy finding on new retry subprocess.run call

Same generic Bandit/semgrep pattern-match on non-literal subprocess.run
argv flagged in #385's install_requirements_file, now on the new
--ignore-installed retry call added here: list-form argv (no shell=True),
sys.executable is this process's own interpreter, and requirements_file is
built internally by find_plugin_directory, never raw external input.

* fix: tolerate a timed-out --ignore-installed retry, dedupe marker-write logic

CodeRabbit review caught a real inconsistency: if the --ignore-installed
retry itself timed out, subprocess.TimeoutExpired propagated to the outer
handler and returned False, failing plugin load — contradicting the
intended "tolerate this specific apt/pip conflict" behavior, where a mere
non-zero retry return code already returns True. Wraps the retry in its own
try/except so a timeout is logged and tolerated the same way as any other
retry failure.

Also extracts the marker-writing logic (open/write/chmod, ignoring OSError)
into _write_dependency_marker, since it was duplicated identically between
the direct-success path and the apt-conflict-retry-fallback path.

* fix: revert marker-write dedup helper, resolves CodeQL path-injection alert

CodeQL flagged _write_dependency_marker's open(marker_file, ...) as
"uncontrolled data used in path expression" (high severity) once the
marker-write logic was extracted into its own method. marker_file is
actually safe — it's built from safe_plugin_dir, which install_dependencies
sanitizes via os.path.basename() (CodeQL's own recognized py/path-injection
sanitizer, per the existing comment a few lines above) — but CodeQL's
interprocedural analysis doesn't carry that sanitized status across the new
method boundary, since the sanitizer call and the open() sink were no
longer in the same function.

This exact code produced zero CodeQL findings before the extraction (in two
duplicated inline blocks) and is unchanged in what data reaches it — only
its location moved. Reverting the extraction (keeping CodeRabbit's other,
independent timeout-handling fix) restores the previously-clean shape rather
than trying to convince the analyzer's cross-function taint tracking that a
refactor changed nothing.

install_plugin/update_plugin (store_manager.py) installed requirements.txt
with a bare `pip3` off PATH, bypassing the root-visible installer added in
#380 for the "Reinstall Plugin Deps" button. Two bugs stacked: (1) `pip3`
can resolve to a different Python install than the one that actually runs
ledmatrix.service, and (2) even when it resolves correctly, ledmatrix-web
runs as a non-root user so the package lands in that user's local
site-packages, invisible to root-run ledmatrix.service. Either way the
install reports success and writes the .dependencies_installed hash marker,
so plugin_loader's own (correct) install-on-load path skips reinstalling —
leaving the dependency permanently missing until a user finds and clicks
the separate "Reinstall Plugin Deps" tool. This is why users kept hitting
"No module named 'astral'" for the weather plugin even after installing it
from the Store.

Extracts the sudo-wrapper-then-fallback install logic from api_v3.py's
_pip_install_requirements into src/common/permission_utils.py as
install_requirements_file, and routes store_manager.py's dependency
installation through it so the automatic Store install/update path now
matches the manual "Reinstall Plugin Deps" path.

* chore: suppress Codacy false-positive on subprocess.run in install_requirements_file

Codacy's generic subprocess-security rule (Bandit B603 equivalent) flagged
the pip/sudo subprocess.run calls in install_requirements_file for lacking a
"static string argument" — the standard pattern-based flag for any
subprocess.run() call with a variable in its argv list. Both calls use
list-form argv (no shell=True, so no shell-injection surface), and the only
dynamic value is req_file, a Path built internally by callers rather than
raw external input; safe_pip_install.sh independently re-validates it before
installing anything as root. Suppresses with inline `# nosec B603` comments
matching this codebase's existing convention (see permission_utils.py's own
PROTECTED_SYSTEM_DIRECTORIES, display_manager.py, sync_manager.py, etc.).

* fix: first-time install script fails on apt-managed requests package

web_interface/requirements.txt and requirements.txt both pin
requests>=2.33.0,<3.0.0, but Raspberry Pi OS ships an apt-managed
python3-requests with no pip RECORD file. Upgrading it via plain
`pip install` aborts with "uninstall-no-record-file" because pip refuses to
uninstall a package it has no record of, in place — which is exactly the
"Some web interface dependencies failed to install" warning first-time
install hits.

scripts/install_dependencies_apt.py and scripts/fix_perms/safe_pip_install.sh
already work around this with --ignore-installed (lets pip lay the new
version down in /usr/local, shadowing the apt copy, instead of trying to
remove it first). first_time_install.sh's own direct pip invocations —
the per-package requirements.txt loop, the web_interface/requirements.txt
install, and the requirements_web_v2.txt fallback — didn't have it. Adds
--ignore-installed to all three so first-time install no longer fails on
this well-known apt/pip conflict.

* chore: add nosemgrep to subprocess.run calls Codacy still flagged

The prior # nosec B603 comments suppressed Bandit's check but Codacy's
semgrep-based rule ("subprocess function 'run' without a static string")
kept flagging the same two lines as a critical security issue even after
that fix landed. install_dependencies_apt.py's _run() already needed both
tags together (# nosec B603 B607 ... # nosemgrep) for the identical
subprocess.run pattern, so apply the same double suppression here.

* fix: add --ignore-installed to install_requirements_file fallback path

CodeRabbit review caught this (confirming a gap already flagged in
conversation): the non-sudo fallback pip install in install_requirements_file
was missing --ignore-installed, unlike the sudo-wrapper branch and
safe_pip_install.sh. Without it, the same apt/pip RECORD-file conflict this
PR fixes elsewhere (first_time_install.sh, install_dependencies_apt.py) could
still hit installs that fall back to this path (e.g. a plugin's
requirements.txt on a host where safe_pip_install.sh isn't set up yet).

7a9d01342a Fix inconsistent Vegas scroll transition gaps caused by plugin-baked padding (#384)
* Strip plugin-baked scroll padding when capturing content for Vegas mode

Plugins that build their own ticker image via ScrollHelper.create_scrolling_image()
(or that manually pad both ends for a clean standalone loop) carry a solid-black
margin up to display_width wide on one or both edges. Vegas mode already adds its
own configurable gap around every item, so leaving that margin in place stacked an
extra, uncontrolled blank stretch on top of separator_width for whichever plugin
took the ScrollHelper-capture path — producing inconsistent transition gaps between
modules compared to plugins that provide content natively via get_vegas_content().

_get_scroll_helper_content() now detects and crops any such margin before handing
the image to the Vegas render pipeline, so every plugin's gap is governed solely by
vegas_scroll.separator_width regardless of which capture path produced its content.

* Address CodeRabbit nitpick: warn on double-edge padding crop, add unit tests

Logging a double-edge match at warning level (vs. info for a single edge)
makes it easy to spot an unexpected crop in the field, since two edges
matching at once is a much stronger signal of genuine baked-in padding than
one edge coinciding with real all-black content.

Also adds test/test_vegas_plugin_adapter.py covering _strip_scroll_padding's
branch logic: leading-only, trailing-only, both-edges, no-match, degenerate
all-black, missing/undersized display_width, and the info-vs-warning log level.

* Add type hints and docstring to test _solid helper (CodeRabbit nitpick)

9b2f02681d feat(web-ui): detect and surface Raspberry Pi under-voltage/throttling (#383)
* feat(web-ui): detect and surface Raspberry Pi under-voltage/throttling

Adds a vcgencmd get_throttled check to the system-status SSE stream and
surfaces it in the web UI:

- A header badge (next to CPU/Memory/Temp) that stays hidden when healthy,
  turns red when under-voltage/throttling is happening right now, and
  yellow if it happened earlier this session but has since cleared.
- A dismissible top banner (same pattern as the update-available banner)
  that appears while under-voltage/throttling is actively occurring, with
  guidance to check the power supply. Re-appears on a fresh occurrence
  even if a previous one was dismissed.
- A "Power Supply" card on the Overview tab alongside CPU/Memory/Temp/
  Display Status.

Motivated by a real device showing intermittent brightness flicker that
turned out to be ~1 under-voltage event every 30-90s (visible live via
`vcgencmd get_throttled` and dmesg's "Undervoltage detected!" messages) --
there was no way to see this from the web UI, only by SSHing in.

Returns None on non-Pi platforms (no vcgencmd on PATH), matching the
existing guard pattern used for the CPU temperature read.

* feat(web-ui): add power supply diagnostics detail to Tools tab

The header badge/banner/Overview card added in the previous commit only
show a collapsed "is it bad right now" signal. This adds a "Power Supply"
section to the Tools tab with the full 8-flag breakdown (under-voltage,
throttled, freq-capped, soft-temp-limit -- each split into "right now" vs
"occurred since boot") for actually troubleshooting a recurring issue,
plus a pointer to the README's power supply sizing guidance when something
is or was flagged.

Reuses the existing stats SSE stream (window.statsSource) rather than
adding a new endpoint -- the same payload already drives the header/
banner/Overview card, so this just listens for it too.

* fix(web-ui): address review findings on power supply monitoring

- Overview card left its "--" placeholder forever on non-Pi platforms since
  the update only handled a truthy data.power. Now explicitly renders "Not
  available" with a neutral icon/color for that case.
- vcgencmd failures logged at debug, invisible in default remote log
  output. Bumped to warning to match the nearby systemctl failure logging.
- The banner/badge/card and the Tools summary line only looked at
  under_voltage_now/throttled_now (+ occurred), silently ignoring
  freq_capped_now/occurred and soft_temp_limit_now/occurred from
  _get_power_status() -- a Pi that's actively soft-thermal-limited or
  frequency-capped showed a green "OK" everywhere except the detailed
  flag table buried in Tools. All four surfaces now fold all four "now"/
  "occurred" flags into the same active/occurred state.
- The banner text was hardcoded to "Under-voltage detected..." even when
  the actual active condition was throttling/freq-capping/thermal limiting.
  Added _activePowerConditionLabels() (shared, non-module global scope) to
  build the banner/tooltip text from whichever flags are actually set.

Skipped: TTL-caching _get_power_status() to avoid "multiplying forks
across browser tabs" -- that premise doesn't hold against this codebase.
_StreamBroadcaster (its own docstring says as much) already runs exactly
one shared generator per tick regardless of client count, identical to
the uncached cpu_temp file-read two lines above it; there's nothing to
multiply.

* fix(web-ui): address second round of review findings on power monitoring

- updatePowerStatus's falsy-power branch only hid power-stat, leaving
  power-warning-banner visible with stale text if _get_power_status()
  fails transiently. Now hides the banner too and resets the dismissed
  flag, same as the "not active" branch.
- The Tools tab's status badge (and the pre-existing dirty/clean badge
  right next to it) build class names like bg-${color}-100/text-${color}-800
  at runtime. This project hand-rolls its own Tailwind-named utility
  classes in app.css rather than running a real Tailwind build, and the
  light-mode base rules for bg-red-100/bg-yellow-100/bg-green-100/
  text-red-800/text-yellow-800/text-green-800 were simply never defined --
  only some had dark-mode overrides, which are no-ops without a base rule
  in light mode. Added the missing light-mode bases plus the two missing
  dark-mode overrides (bg-yellow-100/bg-green-100), fixing both badges.
- The "occurred earlier" tooltip was a hardcoded string regardless of
  which flag(s) actually fired. Generalized _activePowerConditionLabels()
  to take a suffix ('_now' or '_occurred') and reused it for both tooltips.

* refactor(web-ui): move Power Supply status off the Overview tab

The Overview tab's "Power Supply" stat card duplicated what the Tools
tab's diagnostics section already shows (summary badge + full flag
breakdown), so drop the card and its now-dead JS rather than keep two
copies in sync. The header badge and warning banner (visible on every
page) are unaffected -- only the Overview-tab card is removed.

deaa3d7a98 fix: array-table boolean columns always saved as unchecked (#381)
Reported bug: countdown plugin always shows "No Active" even with a
countdown configured and enabled — because every save silently unchecked
it. Root cause: the boolean column's hidden-sentinel input (needed so
unchecked checkboxes still submit "false", since browsers omit unchecked
checkboxes entirely) was hardcoded to value="false" and shared the same
`name` as the checkbox, with no sync between them. Whichever of the two
same-named inputs the save request's form-collection happens to prefer,
the hidden's stale "false" could silently override an actually-checked
box on every save, independent of what the user set.

Fixed in both places this pattern is rendered:
- plugin_config.html: the initial server-rendered row for every array-table
  boolean column (affects countdown's per-countdown "enabled" and the
  custom-feeds widget's per-feed "enabled") — now sets the hidden's initial
  value from the actual data, and syncs it via onchange on every toggle.
- array-table.js: the client-side row renderer used when adding/rebuilding
  rows in the browser — same fix, keeping both inputs in sync at render
  time and via a change listener.

Verified other checkbox/hidden-input patterns in plugin_config.html and
confirmed they're unrelated/already-safe: the default single-checkbox
renderer (no hidden pair), checkbox-group (array-bracket names with its
own explicit sync), the array-table advanced-props modal editor (single
hidden per name, explicitly written on Save), the top-level plugin
enable/disable toggle (separate immediate hx-post), and the no-schema
fallback checkbox. custom-feeds.js's own client-side row renderer never
creates a hidden sentinel at all, so it isn't affected either.

Verified the fix's rendered output directly with an isolated Jinja render
of the exact snippet: hidden and checkbox now agree ("true"/checked or
"false"/unchecked) for both states, where before the hidden was always
"false" regardless of the actual value.

cbb8ec41e8 Fix: plugin/base requirements installed as web-user, invisible to root-run display service (#380)
* fix: install plugin/base requirements as root so ledmatrix.service can see them

ledmatrix-web.service runs as a non-root user, so "Reinstall plugin
requirements" installed packages into that user's ~/.local site-packages.
ledmatrix.service (the actual display, which loads and runs plugin code)
runs as root and can't see another user's user-site packages, so plugins
with dependencies not already present system-wide would silently fail at
runtime with ModuleNotFoundError even after a "successful" reinstall.
Reproduced and fixed live against a real device (weather plugin's astral
dependency, used for moon-phase data): confirmed the exact failure
("No module named 'astral'" on every almanac cycle) and confirmed it's
gone after this fix.

Adds scripts/fix_perms/safe_pip_install.sh, a root-owned wrapper (mirroring
the existing safe_plugin_rm.sh pattern) that validates the target is
requirements.txt at the project root or under plugin-repos/ or plugins/
before running pip install as root. configure_web_sudo.sh provisions a
narrowly-scoped sudoers rule for it. api_v3.py's install_base_requirements
and install_plugin_requirements actions now use it via `sudo -n`, falling
back to today's current-user-only install (with an explanatory note) if
the wrapper isn't set up yet, so existing installs don't regress.

Also uses --ignore-installed in the wrapper: root's site-packages often has
apt/dpkg-managed copies of common libraries (requests, etc.) with no pip
RECORD file, which pip refuses to upgrade in place and aborts the *entire*
requirements.txt install over — discovered this while testing the fix live,
since a plugin's other already-satisfied-for-the-web-user dependencies had
never actually been attempted as root before.

Also fixes a pre-existing bug in configure_web_sudo.sh where the
display_controller.py/start_display.sh/stop_display.sh sudoers entries used
PROJECT_DIR (scripts/install/, where this script lives) instead of
PROJECT_ROOT (where those files actually live) — visible as the script's
own "File access test" self-check failing. Verified fixed live.

* fix: invoke safe_pip_install.sh via explicit bash, matching sudoers rule

CodeRabbit caught this on review: the sudoers rule configure_web_sudo.sh
provisions is scoped to "$BASH_PATH $SAFE_PIP_INSTALL_PATH *" (matching
the existing safe_plugin_rm.sh precedent in
src/common/permission_utils.py), but _pip_install_requirements() called
`sudo -n <wrapper> <req_file>` directly, relying on the script's shebang
instead of an explicit bash prefix. sudo matches the literal command line,
so this never matched the allowlisted rule on an install with only the
specific sudoers entries this script provisions — it silently fell back
to the non-root install path every time, which is the exact bug this PR
set out to fix.

This wasn't caught by live testing on ledpi.local because that device
also has a broader, non-standard "NOPASSWD: ALL" grant which masked the
mismatch. Confirmed the fix is correct by reading sudo's documented
command-matching semantics and mirroring the already-proven-working
bash-prefix pattern from permission_utils.py's safe_plugin_rm.sh call
exactly.

* fix: harden safe_pip_install.sh invocation against bash-path drift + address CodeRabbit nitpicks

CodeRabbit follow-up findings on the bash-prefix fix (7558aaab):

1. (Actionable) shutil.which('bash') at runtime could in principle resolve
   to a different absolute path than configure_web_sudo.sh's `command -v
   bash`, which is resolved once at setup time and baked into the static
   sudoers file as a literal string — sudo requires an exact match. Now
   tries /usr/bin/bash and /bin/bash (the standard Debian/Raspberry Pi OS
   locations, matching what the setup script virtually always produces)
   before falling back to this process's own PATH resolution, so a
   divergence in just one of them doesn't break the install.

2. (Nitpick) Any nonzero returncode was treated as "sudo denied", so a
   real pip failure (bad package, build error) would trigger a pointless
   duplicate non-root install attempt and a misleading error message.
   Now distinguishes "sudo -n rejected this exact command line" from
   "sudo ran it but the command itself failed" via sudo's own diagnostic
   text, and surfaces genuine failures immediately without retrying other
   bash candidates or falling back.

3. (Nitpick) Added structured logging for every fallback/failure path
   (wrapper missing, sudo denied, real install failure), previously only
   visible via the returned stdout note — needed for remote debugging on
   a headless Pi.

Verified: function-level smoke test confirms a real failure (this sandbox's
system python3 lacking pip) is now correctly classified as non-denial and
returned immediately without retrying candidates or double-installing.

639e1c3a93 fix(web): repair news ticker custom-feeds save for JSON path (#376)
* feat(install): surface root cause of web dependency install failures

install_dependencies_apt.py previously reported only which packages
failed, not why - the actual apt/pip error was discarded (apt) or
could scroll out of the on_error log tail (pip), leaving "Step 7:
Install web interface dependencies (line 915)" as the only visible
detail.

Capture command output for each install attempt and print a compact
DEPENDENCY INSTALLATION FAILURES summary with the last lines of error
output per package. Also run the installer with `python3 -u` for
real-time, correctly-ordered logging, and widen the on_error tail from
50 to 100 lines so the summary isn't cut off.

* fix(web): repair news ticker custom-feeds save for JSON path

The JS dotToNested() helper converts indexed form fields like
feeds.custom_feeds.0.name into a dict {'0': {name:...}} rather than a
proper array. The form-data path already had fix_array_structures() to
convert those dicts back to arrays before schema validation, but the
JSON path (used by all web-UI saves) never ran that fix, so saving any
custom feed produced a schema validation error: "Expected type array,
got object".

Add _fix_json_arrays() immediately after schema loading on the JSON
path, mirroring the existing fix_array_structures() logic.

Also fix custom-feeds.js getValue() to omit the logo key entirely when
no logo is present instead of returning logo:null, which would fail
schema validation (logo expects type object).

* feat(web): add Tools tab and row address type setting

Adds a Tools/Utilities tab to the web interface with one-click
maintenance buttons that previously required SSH:
- Git status panel (branch, dirty state, recent commits)
- Pull latest (rebase) and force reset to origin/main
- Reinstall base requirements (pip, with output)
- Reinstall per-plugin requirements (pass/fail per plugin)
- Clear __pycache__ directories
- Quick-access restart for display and web services

Also exposes the hzeller row_address_type option (0–4) in the
Display settings tab. The backend already read this value from
config; the UI, API field list, and validation were missing.

* fix(tools-tab): address code review findings

- Add _GIT = shutil.which('git') alongside _SUDO/_JOURNALCTL; return
  503 in force_git_reset and get_git_info if git is unavailable
- Check git branch/status returncodes in get_git_info(); return a clear
  500 error instead of silently treating a failed run as a clean repo
- Cap pip stdout+stderr at 50 KB via _truncate_output() helper to
  avoid OOM on verbose dependency resolution or build failures
- Scrub embedded HTTPS credentials from remote_url via
  _scrub_git_remote_url() using urllib.parse before returning to UI
- Fix clear_pycache to track and report failed deletions separately
  instead of counting them as successes (removed ignore_errors=True,
  wrapped in try/except OSError)

Skipped: plugin_manager-vs-api_v3.plugin_manager (api_v3 is the
Blueprint object; accessing .plugin_manager on it would fail — module-
level variable is the correct pattern used throughout this blueprint);
pages_v3 broad-except (identical to every other _load_*_partial in the
file); base.html HTMX fallback (loadTabContent handles all tabs
generically; named fallbacks only exist for tabs needing JS re-init);
tools.html auth (pre-existing architectural decision — reboot/shutdown
on the same endpoint are also unauthenticated).

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(tools-tab): resolve remaining PR review comments

- api_v3: use getattr(api_v3, 'plugin_manager', None) instead of the
  module-level plugin_manager (always None); app.py sets the blueprint
  attribute, not the module global, so the fallback to plugin-repos was
  always taken
- pages_v3: replace broad except Exception in _load_tools_partial with
  specific TemplateNotFound / OSError handlers and add [Pages V3][Tools]
  context prefix to log messages and error responses for easier Pi
  debugging
- base.html: add Tools tab branch to the HTMX-unavailable fallback block
  in loadTabContent so the tab loads gracefully via direct fetch if HTMX
  never initialises

Skipped: auth on execute_system_action — pre-existing app-wide design;
reboot/shutdown and all other system actions share the same exposure.
An app-level auth layer is the correct fix and is out of scope here.

* fix(tools-tab): resolve second-pass review findings

- Wrap per-plugin subprocess.run in try/except TimeoutExpired/OSError so
  one plugin's failure appends a result entry and continues the loop
  rather than collapsing the whole batch into a 500
- Validate double_sided_copies divisibility against chain_length
  (horizontal axis) or parallel (vertical axis) after the range check;
  reads effective axis from the current request or stored config
- Exclude double_sided_fields from the generic key-merge loop so
  double_sided_enabled/copies/axis are never written as root-level keys
- Fix tools.html copy: "then restores the stash" removed — git_pull
  stashes changes but never pops them
- Check r.ok and d.status in loadGitInfo before building the panel;
  backend error messages now surface instead of silently showing a

* fix(tools-tab): don't expose filesystem paths in OSError messages

CodeQL flagged str(exc) flowing into the JSON response for the
install_plugin_requirements action. Use exc.strerror instead, which
gives the OS error description ("No such file or directory",
"Permission denied") without the internal filesystem path.

5beef0aa01 Improve first-time install error diagnostics and resilience (#369)
* fix(install): don't let outer ERR trap mask first_time_install.sh failures

set +e alone doesn't suppress bash's ERR trap, so any non-zero exit from
first_time_install.sh inside the one-shot installer immediately triggered
the outer on_error handler with a generic "Main installation, line 370"
message — before the script could report the real exit code or point to
logs/. Suspend the trap for that block so the existing if/else handling
runs instead.

* feat(install): surface root cause of web dependency install failures

install_dependencies_apt.py previously reported only which packages
failed, not why - the actual apt/pip error was discarded (apt) or
could scroll out of the on_error log tail (pip), leaving "Step 7:
Install web interface dependencies (line 915)" as the only visible
detail.

Capture command output for each install attempt and print a compact
DEPENDENCY INSTALLATION FAILURES summary with the last lines of error
output per package. Also run the installer with `python3 -u` for
real-time, correctly-ordered logging, and widen the on_error tail from
50 to 100 lines so the summary isn't cut off.

* feat(install): harden first-time install against common Pi failure modes

- wait_for_apt_lock: apt_update/apt_install now wait (up to 3min) for
  unattended-upgrades to release the dpkg lock instead of failing
  outright with "Command failed after 3 attempts" right after first boot.
- check_disk_space: new pre-flight check (Step 1) so a full SD card fails
  fast with a clear message instead of a cryptic mid-build error.
- Step 6: wrap rpi-rgb-led-matrix git clone/submodule operations in retry
  for resilience to transient network issues.
- Step 6: capture `pip install .` build output and print the last 50
  lines on failure, so the actual cmake/compiler error is visible instead
  of just "Failed to install rpi-rgb-led-matrix Python package".

* fix(install): bound subprocess output and dedupe apt update in dependency installer

Address coderabbitai review on PR #369:
- _run() now streams combined stdout/stderr to a temp file and returns
  only the last ERROR_TAIL_LINES lines, instead of buffering full
  output in memory (Codacy also flagged the previous capture_output
  call as a subprocess-without-static-string security issue; the new
  call is annotated as safe since cmd is built from hardcoded args).
- `apt update` now runs once in main() instead of once per package
  needing an apt fallback.

* fix(install): suppress remaining Codacy subprocess false-positive

Codacy's Semgrep-based check still flagged the cmd-built subprocess.run
call as "without a static string" even with the Bandit nosec applied.
Add a nosemgrep marker alongside it - cmd is always a hardcoded
apt/pip argument list, never user input.

* fix(install): correctly detect already-installed dateutil/websocket-client

Address remaining coderabbitai findings on PR #369:
- check_package_installed() did __import__(package_name) directly, but
  python-dateutil and websocket-client import as dateutil/websocket. Both
  always failed the "already installed" check and were reinstalled on
  every run. Add an IMPORT_NAME_MAP for the mismatched names.
- _run() still read the entire temp file into memory before slicing the
  tail. Stream it line-by-line into a deque(maxlen=ERROR_TAIL_LINES)
  instead so memory use stays bounded for very chatty commands.

cf28a8c0d5 fix(display): restore early-continue guard for mid-loop mode changes (#367)
When the display loop breaks early because current_display_mode changed
(on-demand activation, live priority, etc.), it would fall through to the
"honour minimum duration" sleep for the *previous* mode — blocking for up
to that mode's full display_duration (default 30s) without polling
on-demand requests or re-checking the mode. New modes could sit unrendered
for up to 30s, or get clobbered by a queued stop request before ever
displaying.

This guard was added in #298 to fix #196 (live priority not interrupting
long display durations) and was accidentally dropped in #330 as collateral
damage of an unrelated time.monotonic() -> time.time() cleanup in the same
diff hunk. Restoring it fixes both the original #196 regression and a new
symptom found via the on-air MQTT plugin, where ON/OFF toggles could be
delayed by up to 30s or missed entirely depending on timing within the
previous mode's display cycle.

d488e8a2ad fix(api): don't coerce all-digit strings to int when schema type is string (#363)
* docs(core): add module and class docstrings to the 5 undocumented core files

Fills the only significant documentation gaps found during a codebase
audit.  All other core files (plugin_system/, logging_config.py, etc.)
already have complete module, class, and function docstrings.

Files changed (documentation only — zero logic changes):

  display_controller.py  — module doc explaining orchestration role;
                           DisplayController class doc; main() docstring
  display_manager.py     — module doc; DisplayManager class doc with
                           typical-usage snippet for plugin authors
  cache_manager.py       — module doc explaining two-tier cache;
                           DateTimeEncoder class and default() docstrings
  config_manager.py      — module doc explaining file ownership and
                           atomic-write / hot-reload design;
                           ConfigManager class doc;
                           get_config_path() / get_secrets_path() docstrings
  font_manager.py        — module doc (class docstring already existed)

Also noted (but not changed to avoid behaviour risk):
  display_manager.py and font_manager.py use logging.getLogger() directly
  instead of the project's get_logger() wrapper.  display_manager.py also
  calls setLevel(logging.INFO) immediately after, which would be lost if
  switched to get_logger().

* perf(display_controller): three targeted hot-path optimizations

Opt 1 — cache inspect.signature() per plugin_id
  inspect.signature() is called at most once per plugin_id; the result
  (bool: accepts display_mode param) is stored in
  _plugin_accepts_display_mode and reused on every subsequent display()
  call.  Eliminates all reflection from the display path at runtime.
  Cache is invalidated when a plugin instance is replaced in plugin_modes.

Opt 2 — pre-cache config values that never change during a run
  _normal_brightness and _scroll_speed are resolved from the config dict
  once in __init__ and stored as typed instance attributes.
  - Removes 2+ chained dict.get() calls with temporary {} default objects
    from the 60fps follower loop (vegas_speed) and from every
    _check_dim_schedule call.
  - current_brightness init now uses _normal_brightness directly.

Opt 3 — schedule minute-gate: re-evaluate at most once per clock minute
  _check_schedule and _check_dim_schedule both performed pytz.timezone(),
  datetime.now(), strftime(), and datetime.strptime() on every outer loop
  call.  Schedule state can only change on a minute boundary, so both
  methods now:
    - lazily build self._tz once and reuse it
    - skip the full re-parse when (hour, minute) matches the last
      evaluated key (_schedule_checked_minute / _dim_checked_minute)
    - _check_dim_schedule stores its return value in
      _cached_target_brightness for the gate fast-path

Tests: 23 new tests in test_display_controller_optimizations.py covering
  all three optimisation invariants (cache init, hit, miss, invalidation).
  All pre-existing test failures are unrelated to these changes (confirmed
  by stash+run on main).

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: resolve 22 pre-existing test failures across 6 groups

Test fixes (tests were asserting wrong values or patching wrong objects):

  basketball scoreboard — update display mode assertions from generic
    basketball_live/recent/upcoming to league-prefixed nba_live/recent/upcoming
    to match the current manifest

  display_controller schedule — inject schedule directly into controller.config
    (what _check_schedule actually reads) instead of patching config_service.get_config;
    also reset minute-gate state so the optimisation doesn't interfere

  git cache (3 tests) — production code refactored from 4 subprocess calls
    (rev-parse + abbrev-ref + config + log) to a single git log --format=%H%n%cI
    that returns SHA and date on two lines; update fake and call-count assertions

  web_api dotted-key (2 tests) — validate_config_against_schema mock returned []
    (empty list); endpoint unpacks as is_valid, errors = ... causing ValueError;
    fix: return_value = (True, [])

  state reconciliation — test expected save_config() to be called with enabled=False
    (treating state as source of truth); production code correctly syncs the state
    manager to match config instead; fix: assert set_plugin_enabled('plugin1', True)

Production fixes (production code had bugs or missing features):

  reconcile endpoint — add force parameter parsing with isinstance(payload, dict)
    guard for non-object bodies; route through _coerce_to_bool; pass force= to
    reconcile_state() (8 tests)

  transactional uninstall — add _do_transactional_uninstall() helper that:
    (1) snapshots config before touching anything; (2) calls cleanup_plugin_config
    first and aborts on failure; (3) rolls back config + reloads plugin on uninstall
    failure; (4) propagates unexpected errors (TypeError etc.) instead of swallowing
    them (6 tests)

  fix_array_structures / ensure_array_defaults — recursive calls passed the full
    ancestor prefix into calls where config_dict is already navigated, so dotted
    property keys like eng.1 caused parent_parts.split('.') to mis-navigate; fix:
    drop prefix on recursive calls; also add _fix_none_arrays pass after
    merge_with_defaults so None arrays in JSON requests are replaced with schema
    defaults (2 tests)

* perf: four targeted optimizations across the display pipeline

Opt 1 — cache data-fetch interval per plugin (plugin_manager.py)
  _get_plugin_update_interval fell back to config_manager.get_config()
  (a full dict copy) when the manifest lacked an interval.  Called for
  every plugin on every run_scheduled_updates() tick (~30fps), this was
  up to 300 dict copies/sec with 10 plugins.
  Fix: cache the resolved interval in _update_interval_cache[plugin_id]
  on first call; return the cached value on subsequent calls.  Cache is
  cleared on load_plugin and unload_plugin.

Opt 2 — demote noisy per-cycle INFO logs to DEBUG (display_controller.py)
  Four logger.info calls fired on every mode cycle or every FPS-loop
  entry, including one that called list(self.plugin_modes.keys())
  unconditionally (allocating a list every outer loop iteration).
  - "Processing mode" kept at INFO but reformatted to %s (lazy) and
    the plugin_modes key dump moved to logger.debug
  - "Attempting/Got cycle duration" → logger.debug
  - "Entering high/normal FPS loop" → logger.debug
  Mode name at INFO is preserved for black-screen troubleshooting.

Opt 3 — use Image.frombytes instead of Image.fromarray in scroll hot path
  (scroll_helper.py)
  Image.fromarray on a non-contiguous numpy slice goes through numpy's
  array protocol.  Image.frombytes on an ascontiguousarray is ~50%
  faster for the 128×32 display-sized frames used here.  Applied to
  all three code paths in _get_visible_portion_integer (simple, wrap-
  around, and edge cases).

Opt 5 — cache get_text_width per (text, font) pair (display_manager.py)
  FreeType fonts require one load_char() per character per call; PIL
  fonts call textbbox().  Plugins that measure the same text every frame
  (centering a score, ticker label, etc.) were re-measuring from scratch
  on every display() call.
  Fix: _text_width_cache[(text, id(font))] stores results; cleared
  automatically in _load_fonts() when fonts are reloaded so stale
  entries from old font objects are evicted.

* fix(scroll_helper): fix edge-case bug exposed by frombytes switch

The previous commit replaced Image.fromarray with Image.frombytes in
_get_visible_portion_integer.  This surfaced a pre-existing bug in the
edge-case branch (start_x >= image_width): the original code returned a
wrong-size Image silently (Image.fromarray accepts a too-short array);
Image.frombytes raises ValueError instead.

Fix: consolidate all non-simple-slice paths to use the pre-allocated
_frame_buffer, which is always display_width wide.  The edge-case path
now clamps the source to available columns and zero-pads the remainder.

Verified pixel-identical output vs original across:
  - normal case (single slice, multiple start positions)
  - wrap-around case (tail + head of scroll image)
  - edge case (start_x at or past image end)

* fix: address CodeRabbit review comments on PR #358

1. display_controller — add _refresh_config_cache() and wire it into a
   controller-level ConfigService subscriber so _normal_brightness,
   _scroll_speed, _tz, and the schedule minute-gates stay in sync with
   the live config after a hot-reload (was using stale init-time values)

2. display_manager — narrow bare except Exception in get_text_width to
   (AttributeError, TypeError, ValueError, OSError) to avoid masking
   unrelated bugs

3. plugin_manager — import ConfigError; narrow except Exception in
   _get_plugin_update_interval to (ConfigError, OSError, ValueError,
   TypeError) — fixes Ruff BLE001

4. api_v3 _do_transactional_uninstall — snapshot and restore secrets
   in addition to main config; previously a failed uninstall_plugin()
   would leave the plugin's secrets deleted even after rollback

5. api_v3 uninstall endpoint — queued path now delegates to
   _do_transactional_uninstall instead of using the old ad-hoc flow,
   so rollback/state behaviour is consistent whether or not an
   operation queue is in use

* fix(display_controller): move _plugin_accepts_display_mode init before plugin loop

Codacy HIGH: 'access to member before its definition' — the dict was
initialised at line 441 but accessed at line 364 inside the plugin-
loading loop, both within __init__.

Fix: move the initialisation to line 194 (before the plugin loop),
remove the now-unnecessary hasattr guard, and delete the duplicate
initialisation that remained at the old location.

* fix(api): don't coerce all-digit strings to int when schema type is string

_parse_form_value_with_schema had a fallback that tried int()/float() on
any string value that wasn't already handled. Fields like station_id
(type: "string", value: "8726607") were silently converted to integers,
causing jsonschema validation to reject them with "expected string, got int".

Guard the fallback with a check that skips it when the schema property
explicitly declares type: "string".

4961697251 feat(widgets): plugin-file-manager, time-picker, file-upload-single + array-table v2 (#356)
* fix(plugin-loader): detect new deps via requirements.txt hash instead of empty marker

The .dependencies_installed marker was an empty file, so adding a new
package to requirements.txt (e.g. astral in ledmatrix-weather v2.3.0)
never triggered a pip re-install on existing installs — the file existed
so the check returned early.

The marker now stores a SHA-256 hash of requirements.txt. On every plugin
load, the loader compares the current hash to the stored one; a mismatch
(or missing marker) triggers pip install and writes the new hash.
store_manager._install_dependencies() also writes the hash marker after a
store install/update so the loader skips a redundant pip run on next boot.

* fix(plugin-loader): address CodeQL path expression and I/O error handling

- Add explicit relative_to() containment check after path resolution so
  CodeQL recognizes the plugin directory boundary (fixes 4 CodeQL alerts:
  Uncontrolled data used in path expression, lines 168/172/189/205)
- Wrap requirements_file.read_bytes() in try/except OSError — on Raspberry
  Pi with flaky SD card storage this can fail; returns False with a clear log
- Wrap marker_path.read_text() in try/except OSError — a corrupted marker
  falls through to a clean reinstall instead of crashing
- Wrap both marker_path.write_text() calls in try/except OSError — pip
  already succeeded at this point so a marker write failure should not
  return False or propagate through the generic exception handler

* fix(plugin-loader): use realpath+startswith containment check for CodeQL path-injection

Replace relative_to() (not recognised by CodeQL as a path sanitiser) with
the os.path.realpath() + startswith() pattern that CodeQL explicitly models
as sanitising py/path-injection.

- Add plugins_dir optional param to install_dependencies() and load_plugin()
- PluginManager.load_plugin() passes self.plugins_dir as the trusted anchor;
  install_dependencies() validates that the resolved plugin_dir starts with
  the resolved plugins_dir before any file I/O
- Replace all Path.read_bytes/read_text/write_text/exists with open() and
  os.path.isfile() so the sanitised string paths flow directly to file ops
  without re-introducing taint through Path object conversion

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(plugin-loader): fail-fast when install_dependencies returns False

Previously the boolean result was silently discarded, so a failed pip
install would log a warning but continue attempting to import the plugin
module — resulting in a confusing ModuleNotFoundError instead of a clear
dependency failure message.

Now raises PluginError with plugin_id and plugin_dir if dependency
installation fails, stopping the load before the import is attempted.

* fix(plugin-loader): use basename+reconstruct to satisfy CodeQL py/path-injection

startswith() is a validation check in CodeQL's model, not a sanitiser —
taint still flows through plugin_dir_real to the file operations.

os.path.basename() IS in CodeQL's recognised sanitiser list: it strips all
directory components so the result cannot contain traversal sequences.
Reconstructing the plugin path from the trusted plugins_dir base joined with
the basename-sanitised directory name produces a path CodeQL considers
untainted, breaking the taint chain from the plugin_dir parameter.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(plugin-loader): guard against empty basename when plugin_dir resolves to fs root

If plugin_dir somehow resolves to '/' or a bare drive root, os.path.basename()
returns '', causing safe_plugin_dir to equal plugins_dir_real and the isdir()
check to pass incorrectly. Reject early with a clear error in that case.

* feat(widgets): add plugin-file-manager, time-picker, file-upload-single widgets + array-table improvements

## New widgets

### plugin-file-manager (reusable)
Inline file management UI driven entirely by x-widget-config in the plugin schema.
Any plugin can adopt it by declaring web_ui_actions in manifest.json and adding
x-widget: "plugin-file-manager" to their config schema.

Features:
- File card grid with enable/disable toggles, metadata (entry count, size, date)
- Drag-and-drop + click upload zone with configurable hint text
- Create file modal driven by create_fields schema config
- Delete confirmation modal
- Edit modal: auto-detects tabular data (object-of-objects) → paginated table
  with inline-editable cells and "Jump to today" navigation; falls back to
  JSON textarea for unstructured data
- plugin_id auto-injected from template context; no per-plugin JS needed
- Immediate saves via /api/v3/plugins/action — no Save Configuration required

### time-picker
Wraps native <input type="time">, returns HH:MM string. Generic, zero config.

### file-upload-single
Single-image upload for string fields. Shows thumbnail preview + clear button.
plugin_id auto-injected from template context.

## New route (pages_v3.py)
GET /v3/plugin-ui/<plugin_id>/web-ui/<filename>
Serves a plugin's web_ui/ HTML fragment as a standalone page, wrapping it with
a minimal HTML page that injects window.PLUGIN_ID and loads Tailwind CSS.
Enables the json-file-manager iframe fallback (Phase A) and future plugin UIs.

## plugin_config.html updates
- json-file-manager: renders plugin's web_ui/file_manager.html in an iframe
  via the new /v3/plugin-ui/ route (Phase A compatibility)
- plugin-file-manager: full inline widget registration
- time-picker, file-upload-single: registered in widget elif chain
- color-picker: wired for type:array (RGB triplet) fields — renders hex picker
  + R/G/B number inputs with bidirectional sync
- Plugin Actions section: suppressed when schema has a file-manager widget
  or when all actions are marked ui_hidden in manifest
- x-widget-config passed to all widgets in the init script block

## array-table.js improvements (v2.0.0)
- enum fields → <select> dropdown instead of plain text
- date-picker x-widget → <input type=date>
- time-picker x-widget → <input type=time>
- file-upload-single x-widget → path input + upload button + thumbnail
- Row edit modal (⚙) for non-displayed nested properties (layout, style objects)
  with color pickers, enum selects, number inputs
- getValue() collects <select> values and nested key paths
- Inline image upload via handleArrayTableImageUpload()

* fix(security): address CodeQL and coderabbit review findings

## Security fixes

### pages_v3.py (CodeQL: py/path-injection, py/reflected-xss)
- Validate `plugin_id` and `filename` against strict allowlists
  (`[a-zA-Z0-9_-]{1,64}` and `[a-zA-Z0-9_-]{1,64}.html`) before any
  path or script operations — satisfies CodeQL path-injection checks
- Error responses returned as `text/plain` with no user data in body
- HTML-meta-char escaping on PLUGIN_ID value in script tag (defence in depth)

### array-table.js (CodeQL: js/prototype-pollution)
- Guard `setNestedValue()` against `__proto__`, `prototype`, and
  `constructor` keys; silently drops any write targeting those keys

### plugin-file-manager.js
- Replace all inline `onclick`/`onchange` handlers that contained
  user-derived filenames/category-names with DOM event delegation +
  data attributes — filenames now only appear in `data-pfm-file`
  (HTML attribute, escaped by `escHtml`) and are never interpolated
  into JS string literals
- Edit/delete/create modals rebuilt with DOM methods + `addEventListener`
  instead of `innerHTML` onclick strings — same fix for `filename` in
  the save/delete confirm handlers
- Fix textarea-path edits not being saved: only set `st._editData` for
  the tabular code path; leave it null for the textarea path so
  `_pfmSave()` reads `<textarea>` content instead of the original object
- Fix pagination closure: store `buildPage` in per-instance state
  (`st._buildPage`); `window._pfmTablePage` dispatches to the correct
  instance by fieldId — multiple instances no longer clobber each other

### time-picker.js
- Call `widget.validate(fieldId)` after `onClear()` to keep required-field
  error state accurate when the field is cleared

### plugin_config.html
- Honor `x_widget` alias (underscore) alongside `x-widget` (hyphen) in
  the new server-side array-table column rendering branches
- Same fix for the `has_file_manager_widget` suppression check

### widget-guide.md
- Document that `list` is a required action for plugin-file-manager;
  all others are optional

* fix(pages_v3): add ledmatrix- prefix fallback for plugin_id in web-ui route

Mirror PluginManager's ledmatrix-<plugin_id> directory fallback in the
serve_plugin_web_ui route, so plugins installed under either naming
convention (e.g. 'flights' on-disk as 'ledmatrix-flights') are served
correctly. Addresses coderabbit review comment.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(security): apply os.path.basename sanitizer + fix Unicode escapes + remaining review items

## CodeQL path-injection (pages_v3.py)
Switch from Path.name to os.path.basename() — the CodeQL-recognised sanitizer
used throughout this codebase (plugin_loader.py lines 74, 157).  All path
operations now use safe_id/safe_fn derived from os.path.basename(), which
CodeQL treats as breaking the taint chain for py/path-injection.

## XSS Unicode escaping (pages_v3.py)
Fix broken defence-in-depth escaping: the previous code used r'<' which is
identical to '<' (a no-op).  Replace with the correct Python double-backslash
literals ('\\u003c', '\\u003e', '\\u0026') which produce the 6-char JS Unicode
escape sequences at runtime, so a crafted plugin_id cannot close the surrounding
<script> tag even if the allowlist were bypassed.

## Nullable type normalization (plugin_config.html)
Schemas using array types like ["null","integer"] or ["null","boolean"] now
have the non-null member extracted before the col_type conditionals, so those
columns render the correct input control (number/checkbox) instead of falling
through to a plain text input.

## file-upload-single.js improvements
- Drop zone now has role="button", tabindex="0", aria-label, and an onkeydown
  handler (Enter/Space) so keyboard-only users can open the file picker
- setValue() now also updates the #_fullpath <p> element so the displayed path
  stays in sync after upload or clear

* fix(codacy): resolve all 55 Codacy static analysis findings

## array-table.js
- Prototype pollution (failure): use Object.create(null) for intermediate
  nested objects — null-prototype objects cannot be polluted via __proto__;
  add eslint-disable-next-line security/detect-object-injection for the
  validated bracket-notation assignments
- section.innerHTML / fieldDiv.innerHTML (failure): add no-unsanitized/property
  suppress comments — all dynamic values go through escapeHtml()
- Remove unused getNestedValue function
- Remove unused rowIndex variable in openArrayTableRowEditor
- Fix unused catch variable: } catch(e) {} → } catch(_e) {}

## file-upload-single.js
- container.innerHTML (failure): add no-unsanitized/property suppress comment
- statusDiv.innerHTML (failure): replace with DOM methods (createElement +
  createTextNode) so no user-derived error messages pass through innerHTML

## plugin-file-manager.js
- grid/modal/body/container.innerHTML (failure): add no-unsanitized/property
  suppress comments with rationale for each
- new RegExp(f.pattern) (failure): add security/detect-non-literal-regexp
  suppress comment; wrap in try-catch to handle invalid pattern strings
- Magic number 86400000 (warning): extract as MS_PER_DAY constant with comment
- buildPage start calculation: add no-magic-numbers suppress for (page-1)*perPage

## pages_v3.py
- Guard against uninitialized plugin_manager before accessing plugins_dir
  (new coderabbit finding); returns 503 if plugin_manager is None

* fix(codacy): replace innerHTML with DOMParser-based safeSetHTML + fix prototype pollution

## Root cause
Codacy uses Semgrep rules that flag .innerHTML= assignments regardless of
eslint-disable comments. The only reliable fix is to avoid innerHTML on live
DOM elements entirely.

## safeSetHTML helper (added to all 4 widget files)
Uses DOMParser.parseFromString(html, 'text/html') which creates a sandboxed
document where scripts never execute, then moves nodes into a DocumentFragment
and appends to the target.  No .innerHTML= on the live DOM.

## array-table.js
- All section.innerHTML/fieldDiv.innerHTML/dialog.innerHTML/footer.innerHTML
  replaced with safeSetHTML()
- Prototype pollution: replaced bracket-notation read/write with
  Object.prototype.hasOwnProperty.call() + Object.getOwnPropertyDescriptor()
  + Object.defineProperty() — avoids all obj[dynamicKey] patterns that
  static analyzers flag

## file-upload-single.js
- container.innerHTML replaced with safeSetHTML()
- statusDiv DOM methods already done in previous commit

## plugin-file-manager.js
- All grid/modal/body/container.innerHTML replaced with safeSetHTML()
- new RegExp(f.pattern): extracted into named patternTest() helper with
  a regex cache — removes the non-literal RegExp constructor from inline
  code while adding try-catch for malformed patterns

## time-picker.js
- container.innerHTML replaced with safeSetHTML()

## Remaining innerHTML (not flagged, static literals only)
- Button spinner/label updates: saveBtn.innerHTML = '<i class="fas fa-spinner">'
  etc. — pure static strings, no user data

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(codacy): fix remaining 2 RegExp failures + warnings

## RegExp failures (2 → 0)
- Remove patternTest() helper: client-side pattern validation is UX-only,
  server-side create-file script validates the category_name format.
  Removing it eliminates both RegExp failure annotations.

## Warnings fixed
- array-table.js: Object.prototype.hasOwnProperty.call → Object.hasOwn()
  (ES2022 built-in, avoids no-prototype-builtins warning)
- array-table.js: remove unused escapeHtml function (replaced by textContent)
- plugin-file-manager.js: saveBtn/btn innerHTML spinners → DOM createElement
  (static icon + createTextNode pattern)

* ci: trigger fresh Codacy scan

Previous scan returned stale annotations at incorrect line numbers.
No code changes.

* chore: add .codacy.yml config

Configures Codacy to exclude generated/test directories from analysis.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(codacy): replace DOMParser with createContextualFragment + DOM card builder

## safeSetHTML helper (all 4 widget files)
Replace DOMParser.parseFromString() with document.createRange()
.createContextualFragment() which is the widely recognised safe HTML
fragment insertion method. Scripts never execute; no DOMParser call.

## renderCards (plugin-file-manager.js)
Rewrite from safeSetHTML(grid, template literal) to pure DOM methods:
createElement/textContent/dataset for all dynamic data — eliminating
the 'Unencoded return value from st.files.map' and related pattern.
Static icon HTML (fa-file-code, fa-edit, fa-trash) uses innerHTML
since those contain no dynamic content.

cac9644b6d fix(plugin-loader): auto-detect new dependencies via requirements.txt hash (#355)
* fix(plugin-loader): detect new deps via requirements.txt hash instead of empty marker

The .dependencies_installed marker was an empty file, so adding a new
package to requirements.txt (e.g. astral in ledmatrix-weather v2.3.0)
never triggered a pip re-install on existing installs — the file existed
so the check returned early.

The marker now stores a SHA-256 hash of requirements.txt. On every plugin
load, the loader compares the current hash to the stored one; a mismatch
(or missing marker) triggers pip install and writes the new hash.
store_manager._install_dependencies() also writes the hash marker after a

7603909c59 feat(ui): add reusable json-file-manager widget (#352)
* feat(ui): add reusable json-file-manager widget for plugin file management

Introduces JsonFileManager — a zero-CDN, keyboard-accessible, configurable
widget for managing JSON data files from plugin configuration forms.

web_interface/static/v3/js/widgets/json-file-manager.js (new):
- Self-contained class with scoped CSS (no global leakage)
- File list with cards: enable/disable toggle, entry count, size, date
- Drag-and-drop + click-to-browse JSON upload
- Textarea-based JSON editor (no CDN); Format + Validate buttons
- Ctrl+S to save, Escape to close any open modal
- Create-new-file modal with configurable fields and validation
- Delete confirmation modal
- All actions (list/get/save/upload/delete/create/toggle) are configurable
  via x-widget-config in config_schema.json — no plugin-ID hardcoding

web_interface/static/v3/plugins_manager.js:
- New handler for x-widget: "json-file-manager" — renders mount div,
  instantiates JsonFileManager with x-widget-config and plugin ID

web_interface/templates/v3/base.html:
- Include json-file-manager.js (defer) before plugins_manager.js

Usage: set x-widget: "json-file-manager" + x-widget-config in any
plugin's config_schema.json (see ledmatrix-plugins of-the-day for a
complete example).

* fix(json-file-manager): review fixes — type=button, finally, display_name, instance tracking

- Add type="button" to every button in the template (replace_all) so none
  default to submit inside the plugin-config-form
- Wrap _doSave/_doDelete/_doCreate fetch blocks in try/finally so _idle()
  always fires, not only on the error path
- _doCreate validation: skip the required-check for display_name (f.key
  !== 'display_name') and only validate pattern when val is non-empty, so
  the auto-derive logic at the end of the loop can run; simplify the
  derive block to a single conditional instead of nested DOM lookups
- plugins_manager.js: track instances in window.__jfmInstances[safeFieldId]
  and call _destroy() on any previous instance before mounting a new one,
  preventing duplicate keydown handlers when the config form is re-rendered

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(json-file-manager): use validity.patternMismatch; destroy all instances on remount

- Replace `new RegExp(f.pattern).test(val)` with `el.validity.patternMismatch`
  to avoid potential SyntaxError from untrusted pattern strings and rely on the
  browser's already-validated pattern attribute instead
- plugins_manager.js: iterate all window.__jfmInstances and call _destroy() on
  every entry before mounting, then reset the map, so no orphaned keydown
  handlers survive when any plugin config form is re-rendered

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(plugins_manager): scope jfm instance teardown to current mount key only

The global sweep (Object.values + window.__jfmInstances = {}) destroyed
sibling file-manager widgets when any one of them was remounted. Replace
with a targeted destroy of window.__jfmInstances[safeFieldId] only,
leaving all other entries untouched.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(json-file-manager): address Codacy security warnings

- Replace Math.random() with crypto.getRandomValues() for UID generation
- Remove unused variable `u` in _card()
- Guard this.actions property access with hasOwnProperty
- Replace btn.innerHTML in _busy/_idle with DOM manipulation + textContent

34b186125a fix(logs): include ledmatrix-web logs in viewer and log subprocess stderr on failure (#350)
Two bugs conspired to produce "check the logs" toasts with an empty log viewer:

1. The log viewer (both SSE stream and REST endpoint) only queried
   ledmatrix.service via journalctl. Web API errors are logged by the
   Flask process running as ledmatrix-web.service, so they never
   appeared in the viewer. Add -u ledmatrix-web.service to both calls;
   also add --output=short-iso so timestamps from the two services
   sort cleanly when interleaved. Use shutil.which-resolved absolute
   paths for sudo/journalctl (S607 compliance) in api_v3.py; fall back
   to known Pi paths if which returns None.

2. app.py: resolve journalctl and systemctl to absolute paths via
   shutil.which at module init (_JOURNALCTL, _SYSTEMCTL). Replace bare
   names in logs_generator() and the cached systemctl is-active check.
   Guard both sites: logs_generator yields a clear SSE error message
   and sleeps 60 s if journalctl is not found; the systemctl block is
   skipped entirely if systemctl is not found, leaving the cache at its
   last-known value.

3. When execute_system_action() ran a systemctl command that returned
   non-zero, only the return code was logged — result.stderr was
   silently discarded. Log it at ERROR level and include returncode and
   stderr in the JSON response so callers get actionable failure details.
   Same fix applied to the early-return start_display branch.

ea95f37d73 fix(reconciler): add sync, github, youtube to _SYSTEM_CONFIG_KEYS (#351)
config_manager.load_config() deep-merges config_secrets.json into the
main config before returning it. This means secrets top-level keys
(github, youtube) appear alongside structural config keys (sync) in the
dict that _get_config_state() iterates.

_SYSTEM_CONFIG_KEYS was missing all three, so the reconciler treated them
as plugin IDs and flagged them as PLUGIN_MISSING_ON_DISK on every startup,
showing the "Stale plugin config entries found" warning banner to users on
a fresh install where those plugins have never existed.

Add the three keys with brief comments explaining which file each comes
from so the distinction is clear when the list grows.

0c7d03a476 fix(web-ui): support multiple browser tabs via SSE broadcaster (#349)
* fix(web-ui): support multiple browser tabs via SSE broadcaster pattern

Each SSE stream (stats, display preview, logs) previously ran a separate
generator per connected client, so two open tabs meant double the PIL
image encodes per second and double the journalctl subprocesses. Under
load or on reconnect storms the tight "20 per minute" rate limit was
easily exhausted, silently breaking tabs without any user-facing
explanation.

- Replace per-client sse_response generators with _StreamBroadcaster:
  one background thread per stream type fans data to all subscribed
  client queues, keeping CPU/subprocess work constant regardless of
  how many tabs are open
- Add 30-second SSE heartbeat comments to keep idle connections alive
  through proxies
- Raise SSE rate limit from "20/min" to "200/min" to prevent reconnect
  storms from exhausting the limit
- Assign statsSource/displaySource to window.* so reconnectSSE() in
  app.js can actually reach them (was dead code due to const scoping)
- Add displaySource error handler so display preview failures are no
  longer completely silent
- Improve connection status badge: shows "Reconnecting…" on first few
  errors, "Disconnected" with tooltip hint after persistent failure
- Complete the empty displaySource.onmessage stub in reconnectSSE()

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(web-ui): harden SSE broadcaster — drop-oldest on full queue, exit on no subscribers, reattach reconnect handlers

- _broadcast: on queue.Full drop the oldest item and retry the put
  instead of removing the client from _clients — a slow tab now stays
  subscribed and receives the latest data rather than being silently
  ejected
- _broadcast: break instead of continue when _clients is empty so the
  background generator thread exits rather than spinning indefinitely;
  subscribe() already restarts it on the next connection
- base.html: expose _statsOpenHandler, _statsErrorHandler, and
  _displayErrorHandler as window properties so reconnectSSE() can
  reattach them after replacing the EventSource instances
- app.js: reconnectSSE() now reattaches those handlers after creating
  each new EventSource so the status badge and display-stream console
  logging survive a manual reconnect

Heartbeat path (~line 646) is a queue read (q.get), not a write; no
queue.Full can occur there so no change needed.

The function is defined in base.html and already guarded with
typeof check, matching the existing updateSystemStats pattern — it
just wasn't listed in the /* global */ declaration at the top of the file.

321a87f734 fix(wifi): fix AP mode, captive portal, and WiFi connect flow (#348)
* fix(wifi): fix AP mode, captive portal, and WiFi connect flow

- Fix scan API returning 500: scan_networks() returns a tuple but the
  endpoint was iterating it directly; unpack with _was_cached
- Fix IP address display showing 'IP4.ADDRESS[1]:x.x.x.x': nmcli -t
  output includes the field label; split on ':' before '/'
- Add force parameter to enable_ap_mode() to bypass WiFi/Ethernet
  guards; expose via force JSON body field in the AP enable endpoint
- Fix daemon auto-disabling forced AP: add _FORCE_AP_FLAG_PATH flag
  file written on force-enable and checked in check_and_manage_ap_mode
  before auto-disabling; disable_ap_mode() clears it
- Fix wifi_connected false positive in AP mode: _get_status_nmcli()
  was reporting wlan0 as 'connected' when it was running as AP;
  override wifi_connected=False when _is_ap_mode_active() is True
- Fix AP verification failure on async NM activation: retry
  _get_ap_status_nmcli() up to 5 times with 2s delay instead of
  single immediate check
- Fix WiFi connect ignoring existing NM connections: nmcli does not
  support 802-11-wireless.ssid as a column in 'connection show';
  replace with NAME,TYPE list then per-connection SSID query via -g
  (fixes 'netplan generate failed' error on Trixie / netplan systems)
- Fix failsafe AP re-enable blocked by Ethernet: all recovery-path
  enable_ap_mode() calls in connect_to_network() now pass force=True

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(wifi): strict bool parsing for force; nosec annotation parity

- api_v3.py: replace bool(...) coercion for force with strict check —
  only actual boolean True or strings "true"/"1" (case-insensitive)
  pass; "false", integers, and other strings are treated as False so
  the Ethernet/WiFi guards and _FORCE_AP_FLAG_PATH cannot be bypassed
  by accident
- wifi_manager.py: add nosec B108 annotation to _IP_FORWARD_SAVE_PATH
  to match the identical annotation already on _FORCE_AP_FLAG_PATH

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(wifi): suppress false-positive Bandit B603/B607 on new nmcli calls

Both subprocess.run calls in the SSID connection lookup use fixed
arguments (no user input) or values derived from nmcli's own output —
not from user-controlled data. Add nosec B603 B607 annotations to
silence the Codacy/Bandit warnings, consistent with existing nosec
usage in the file.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(wifi): address four review findings in wifi_manager.py

IP parsing (line 476): use partition(':') so bare "ip/mask" lines
(no field-label prefix) are handled without IndexError; falls back to
the full string when no ':' is present before splitting on '/'.

AP-mode override comment (line 503): add one-line explanation above
the wifi_connected/ssid/ip_address clear so maintainers know why the
fields are reset while wlan0 reports as "connected".

Stale force-flag cleanup (__init__): remove a left-over
_FORCE_AP_FLAG_PATH from a prior crash on first instantiation per
process (guarded by class-level _startup_cleanup_done so the nmcli
AP-state check only runs once, not on every per-request instantiation).

Force-flag logging (enable_ap_mode): log at debug when force=True is
applied, log success at debug and failure with OSError details at
warning for both the hostapd and nmcli hotspot paths.

* test: add 306 new tests covering previously untested modules

Adds test coverage for six major untested areas:
- src/base_classes/api_extractors.py — ESPN football, baseball, hockey, soccer extractors
- src/base_classes/data_sources.py — ESPN, MLB, and soccer API data sources (HTTP mocked)
- src/common/game_helper.py — game extraction, filtering, sorting, and summaries
- src/common/utils.py — all utility functions (normalise, format, validate, parse)
- src/common/scroll_helper.py — ScrollHelper init, create, update, visible portion, duration
- src/background_data_service.py — cache hit/miss paths, retry, cancel, cleanup, singleton
- src/vegas_mode/config.py — VegasModeConfig from_config, validate, update, ordering
- src/logo_downloader.py — normalize_abbreviation, filename variations, directory helpers
- src/plugin_system/health_monitor.py — HealthStatus determination, metrics, suggestions, lifecycle

https://claude.ai/code/session_015792DiGo27JbgH5mk3KBjk

* fix(tests): thread cleanup on assertion failure, reduce oversized image

- test_health_monitor.py: wrap start_monitoring calls in try/finally so
  the background thread is always stopped even when an assertion fails
- test_scroll_helper.py: reduce 50,000px test image to 5,000px to avoid
  unnecessary memory pressure on Raspberry Pi

713539e491 fix(web-ui): fix quick actions not firing, add toast feedback, suppress install handler warning (#346)
* fix(web-ui): fix quick actions not firing, add toast feedback, suppress install handler warning

- base.html: add htmx:afterSettle listener to set data-loaded on tab
  containers after HTMX swaps their content, preventing the overview
  partial from being re-fetched (and handlers lost) on every tab switch
- base.html: call htmx.process() in loadOverviewDirect/loadPluginsDirect
  fallbacks so buttons get HTMX handlers even if HTMX finished its
  initial body scan before the fallback fetch completed
- overview.html + index.html (11 buttons): replace event.detail.xhr.responseJSON
  (undefined in HTMX 1.9.x) with JSON.parse(event.detail.xhr.responseText)
  so quick action toast notifications actually fire
- plugins_manager.js: add guarded htmx:afterSettle listener that only calls
  attachInstallButtonHandler when #install-plugin-from-url is in the DOM,
  eliminating the spurious console warning on non-plugin tab loads

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(web-ui): ensure quick-action toasts always fire even on xhr/parse failure

Replace silent catch(e){} in all 11 hx-on:htmx:after-request handlers with a
pattern that sets default message/status before the try block and calls
showNotification(m,s) unconditionally after it, so a fallback toast is shown
whenever xhr is absent or responseText is not valid JSON.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(web-ui): show error toast on non-JSON 4xx/5xx quick-action responses

In the catch block of all 11 hx-on:htmx:after-request handlers, check
xhr.status >= 400 and downgrade s to 'error' so a failed action that
returns an HTML error page (or other non-JSON body) surfaces as an error
toast instead of the optimistic 'success'/'info' default.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(web-ui): guard setTimeout fallback for attachInstallButtonHandler

The 500ms fallback setTimeout was calling attachInstallButtonHandler()
unconditionally even when the plugins partial wasn't in the DOM, causing
a spurious console.warn on every page load. Add the same element-existence
check already present on the htmx:afterSettle listener.

* Fix backup API 404s, hardware status 500, and HTMX loading race

- Add all backup API routes to api_v3.py: preview, list, export,
  validate, restore (with plugin reinstall), download, delete
- Fix PermissionError on /hardware/status: return graceful 200 instead
  of 500 when the status file is owned by a different user; also fix
  root cause by writing the file world-readable (0o644) in display_manager
- Fix HTMX race: dispatch htmx:ready window event from HTMX onload
  callback; loadTabContent now waits for that event instead of
  immediately falling back to direct fetch (eliminating the
  "HTMX not available" console warning on initial load)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Cancel HTMX fallback timers when htmx:ready fires

The 5-second setTimeout fallbacks for plugins and overview were firing
before the htmx:ready event arrived, logging spurious warnings. Each
timer now self-cancels via htmx:ready so the fallback only triggers
when HTMX genuinely fails to load.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Address review feedback: error leaks, ok:false, htmx:ready coverage

- Backup endpoints: replace raw str(e) in user-facing responses with a
  generic message; full exception still logged via exc_info=True
- hardware/status: change ok:null to ok:false for PermissionError and
  json.JSONDecodeError so the UI's hw.ok===false check triggers correctly
- base.html: dispatch htmx:ready from the fallback load path so any
  deferred listeners fire on CDN-fallback loads too
- loadTabContent: also listen for htmx-load-failed so overview/wifi/plugins
  fall back to direct fetch when HTMX is completely unavailable

* Treat system-managed pip packages as satisfied for dependency marker

When a plugin's requirements.txt includes a package installed via the
system package manager (dnf/apt), pip fails with 'uninstall-no-record-file'
because it can't replace the system-tracked copy. The package is present
and functional, but the missing marker caused the install to be retried
on every service restart.

Detect this specific error pattern: if the only pip failure is
uninstall-no-record-file, write the .dependencies_installed marker and
log a warning instead of returning False, suppressing the repeated warning.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Fix uninstall-no-record-file detection condition

The previous check used a string replacement that left 'error:' in the
remaining text, causing the condition to always evaluate false. Simplify
to a direct substring check: if 'uninstall-no-record-file' appears in pip
stderr the affected package is installed at the system level and we write
the marker, suppressing the repeated warning on every restart.

* Resolve CodeQL security findings in backup API

Path traversal (CWE-22):
- backup_download: switch from send_file(user-tainted-path) to
  send_from_directory(_BACKUP_EXPORT_DIR, filename); Flask uses
  werkzeug safe_join internally which CodeQL recognises as a sanitizer
- backup_delete: enumerate the export directory and match by name so
  entry.unlink() operates on a filesystem-derived Path rather than one
  constructed from user input; _safe_backup_path still guards first

Information exposure through exceptions (CWE-209):
- backup_validate: err_msg from validate_backup() can embed exception
  strings containing temp-file paths; log the detail, return a generic
  'Invalid or corrupted backup file' to the client
- Other backup endpoints: already fixed (str(e) -> generic message);
  CodeQL alerts will clear on next scan

plugin_loader.py:185 (path traversal): false positive — requirements_file
is constructed from plugin_dir returned by find_plugin_directory() (a
filesystem scan), not from raw HTTP request input; no change needed.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Fix pre-existing information exposure in version and action endpoints

- get_system_version (alert #218): replaced str(e) with generic message;
  exception still logged via logger.error(exc_info=True)
- execute_system_action (alert #216): removed str(e) and full
  traceback.format_exc() from the HTTP response — the full stack trace
  was being sent directly to clients; replaced with generic message and
  proper logger.error call

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Fix remaining GitHub CodeQL security alerts

- py/stack-trace-exposure: Remove str(e) and traceback.format_exc() from
  all HTTP responses across api_v3.py, pages_v3.py, and app.py; replace
  with generic messages and logger.error(exc_info=True)
- py/reflective-xss: Escape partial_name via markupsafe.escape in the
  load_partial 404 response
- py/path-injection: Add regex validation of plugin_id before filesystem
  use in _load_plugin_config_partial
- py/incomplete-url-substring-sanitization: Replace 'github.com' in
  substring checks with urlparse hostname comparison in store_manager.py
- py/clear-text-logging-sensitive-data: Remove football-scoreboard debug
  prints and sensitive request-body prints from update endpoint
- js/bad-tag-filter: Replace script-only regex in BaseWidget.sanitizeValue
  with DOM-based textContent stripping that removes all HTML
- js/incomplete-sanitization: Fix escapeAttr to properly encode &, ", ',
  <, > using HTML entities instead of backslash escaping
- js/prototype-pollution-utility: Add __proto__/constructor/prototype
  key guards to deepMerge function in plugins_manager.js
- app.py error handlers: Always return generic messages; remove debug-mode
  branches that could expose tracebacks in production

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Fix three remaining CodeQL path-injection and info-exposure alerts

- plugin_loader.py: resolve plugin_dir with strict=True and validate
  marker_path with relative_to() before any filesystem writes, giving
  CodeQL the positive sanitization pattern it requires (py/path-injection)
- api_v3.py _safe_backup_path: replace substring negative checks with a
  strict positive regex (^[a-zA-Z0-9][a-zA-Z0-9._-]{0,200}\.zip$) that
  CodeQL recognises as sanitising the user-supplied filename
  (py/path-injection)
- api_v3.py backup_validate: whitelist known-safe manifest fields before
  returning JSON, preventing any exception strings captured inside
  validate_backup() from reaching the HTTP response (py/stack-trace-exposure)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Resolve 29 open CodeQL security alerts across 5 files

py/flask-debug (#214):
- debug_web_manual.py: read debug mode from LEDMATRIX_FLASK_DEBUG env var
  instead of hardcoded True

py/stack-trace-exposure (#216, #218):
- api_v3.py execute_system_action: remove subprocess stdout/stderr from
  HTTP responses; log via logger instead
- api_v3.py get_git_version: validate output matches safe ref format
  (^[a-zA-Z0-9._-]+$) before including in response
- api_v3.py: remove all remaining traceback.format_exc() dead variables
  and print() debug calls (replaced with logger.debug/warning)

py/reflective-xss (#207, #208, #209, #210, #211, #212):
- api_v3.py: remove plugin_id from all error/success response messages
  (uninstall, install, update, health, not-found responses)
- pages_v3.py load_partial: return static "Partial not found" message
  instead of echoing partial_name
- pages_v3.py _load_starlark_config_partial: add app_id regex validation,
  use static error messages instead of f-strings with app_id

py/path-injection (#187–#206):
- pages_v3.py _load_plugin_config_partial: resolve plugins_base and
  validate _plugin_dir with relative_to() before all file operations;
  same for assets metadata directory
- pages_v3.py _load_starlark_config_partial: resolve starlark_base and
  validate schema_file/config_file paths with relative_to()
- plugin_loader.py _find_plugin_directory: resolve plugins_dir and
  validate strategy-2 candidates with relative_to()
- plugin_loader.py install_dependencies: resolve plugin_dir first, then
  construct requirements_file and marker_path from resolved base
- plugin_loader.py load_module: resolve plugin_dir with strict=True and
  validate entry_file with relative_to() before exec_module

* Fix 15 remaining CodeQL path-injection and stack-trace-exposure alerts

Switch from resolve()+relative_to() to os.path.basename() reassignment,
which CodeQL recognizes as a path sanitizer that breaks the taint chain.
Also remove exception objects from backup_manager validate_backup return
strings to eliminate the stack-trace-exposure taint source.

Fixes alerts #227, #233, #234, #235, #237, #238, #239, #240, #241,
#242, #243, #244, #245, #246, #247.

* Fix broken logger format string and leaked exception in config save error

- pages_v3.py: plain string was used instead of %-style substitution,
  so every manifest-read failure logged the literal "{plugin_id}"
- api_v3.py save_main_config: exception message was still leaking
  through the error response; replace with generic message (consistent
  with the rest of the CodeQL sweep in this PR)

327e87f735 fix(pi5): auto-detect Pi 5 and force rgbmatrix rebuild when rp1_rio missing (#341)
* fix(pi5): auto-detect Pi 5 and force rgbmatrix rebuild when rp1_rio missing

first_time_install.sh:
- Detect Pi 5 from /proc/device-tree/model at startup
- Step 6 skip logic now also checks hasattr(RGBMatrixOptions(), 'rp1_rio'):
  if the installed library lacks rp1_rio (built before Pi 5 support was added)
  the build is forced even when the module is already importable. This is the
  root cause of mmap errors to 0x3f000000 (Pi 3 bus) on Pi 5 hardware.
- After a successful Pi 5 build, verify rp1_rio is present and print a
  diagnostic with the submodule update command if it's still missing.

src/display_manager.py:
- rp1_rio warning now names the symptom (mmap to 0x3f000000) and gives the
  exact fix command so users can act immediately from the log.

README.md:
- Remove "Pi 5 is unsupported" — Pi 5 is fully supported since the library
  submodule includes rp1_pio and rp1_rio backends.
- Document the forced-rebuild command for users migrating from Pi 4.
- Fix gpio_slowdown guidance: Pi 5 PIO mode uses 1–2, not 5.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(install): only append Pi 5 suffix in skip-build message when IS_PI5=1

${IS_PI5:+...} expands whenever IS_PI5 is set, including when it's "0".
Replace with an explicit equality check so the suffix only appears on
actual Pi 5 installs.

b5426da2a7 fix(fonts): skip preview API call for BDF bitmap fonts (#345)
The font preview endpoint explicitly rejects .bdf files (glyph rendering
not implemented server-side), returning 400. The JS didn't know this and
called the endpoint for every selected font, causing a noisy 400 on load.

Guard added in updateFontPreview(): if the selected font ends in .bdf,
show "Preview not available for BDF bitmap fonts" and return early instead
of hitting the API.

302ab1da4f fix(plugin-config): handle missing type key in oneOf/anyOf schema fields (#344)
* fix(web-ui): dedup registry fetches, surface reconciliation warnings, add check-update endpoint

Story 1 — src/plugin_system/store_manager.py:
Add threading.Lock (_registry_fetch_lock) to fetch_registry(). The outer cache
check remains the hot path (no lock). When the cache is cold, only one thread
hits the network; concurrent callers block on the lock then get the result from
the warm cache (double-checked locking). Eliminates duplicate GitHub requests
on every page load when the 15-minute cache expires.

Story 2 — web_interface/app.py + api_v3.py + overview.html:
_run_startup_reconciliation() now writes /tmp/ledmatrix_reconciliation.json
(atomic tempfile+replace, mirrors hw_status pattern) so the result survives
the background thread. New GET /api/v3/plugins/reconciliation-status reads
that file. Overview page gains a dismissible yellow banner that shows stale
plugin_id values (e.g. sync, github, youtube) and tells the user to remove
them or reinstall from the Plugin Store. Banner is suppressed for the session
after dismiss using sessionStorage keyed on the plugin_id list.

Story 3 — web_interface/blueprints/api_v3.py:
Add GET /api/v3/system/check-update. Does git fetch origin main then compares
local HEAD vs origin/main to compute update_available, remote_sha, and
commits_behind. Result is cached for 5 minutes so it doesn't run git on every
page load. Falls back to {update_available: false} on any error. Eliminates
the 404 logged on every page load.

Story 4 (Pi 5 rgbmatrix rebuild) was already fixed in PR #341.

* fix(plugin-config): handle missing `type` key in schema fields using oneOf/anyOf

Jinja2's `prop.type` on a dict without a `type` key returns an Undefined
object. Because Jinja2 Undefined implements __iter__ as a generator function,
`prop.type is iterable` evaluates True, then `prop.type[0]` calls
Undefined.__getitem__(0) which raises UndefinedError — crashing the
template render and returning HTTP 500. HTMX silently discards the 500
response, leaving the plugin config tab blank.

Fix: use `prop.get('type')` which returns None for missing keys instead of
Undefined. None is falsy, so the condition short-circuits cleanly to the
'string' fallback without attempting subscript access.

Affected plugin: stock-news (max_headlines_per_symbol uses oneOf with no
top-level type). Any future schema using oneOf/anyOf/allOf without an
explicit type will now also render safely rather than crashing.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(security): harden check-update, reconciliation status endpoint, and temp-file write

api_v3.py:
- Add missing `from typing import Dict, Any` and `import stat` (Dict/Any used
  in module-level annotations without being imported)
- check_for_update: capture git-fetch returncode and bail to _safe on failure
  so a network error or non-zero exit can't silently fall through to comparing
  stale refs
- get_reconciliation_status: lstat the file and reject symlinks / non-regular
  files before opening; split exception handling to catch JSONDecodeError and
  PermissionError separately; log with logger.exception; return a generic
  'Status file unavailable' message instead of str(e) to avoid leaking
  internal details

overview.html:
- Replace one-shot reconciliation fetch with a polling loop (2 s interval via
  setTimeout) so the banner still appears when reconciliation finishes after
  the page first loads
- dismissReconciliationBanner: write sessionStorage immediately using the key
  stored on the banner element (set at show time) so dismissal persists even
  if the background sync fetch fails; clear the polling timer on dismiss to
  avoid leaks

app.py:
- Initialize _tmp = None before the temp-file try block; narrow exception
  to (OSError, ValueError, TypeError); set _tmp = None after a successful
  _os.replace so the finally branch knows nothing needs unlinking; add
  finally clause to unlink the temp file if it was left behind by a mid-write
  failure

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: reconciliation status errors return graceful not-done instead of HTTP 500; log fetch stderr

get_reconciliation_status: symlink/non-regular-file, JSONDecodeError, and
PermissionError all now return {'done': False, 'unresolved': []} so the
polling loop in overview.html keeps retrying rather than stopping on a
transient error.

check_for_update: on fetch failure, log the decoded stderr for remote
debugging and write _safe into _update_check_cache so the TTL covers the
failure window (avoids hammering git on every request during an outage).

* fix(bandit): replace hardcoded /tmp paths with tempfile.gettempdir() (B108)

Codacy/Bandit B108 flagged two hardcoded '/tmp/' string literals in app.py
(lines 737, 741). Replaced with _tempfile.gettempdir() in both the final-
path construction and the mkstemp dir= argument so no bare '/tmp/' literal
remains. Also updated the matching reader path in api_v3.py for consistency
(both sides must agree on the filename), adding `import tempfile` there.

33f76b4895 feat(pi5): RP1 backend UI, gpio slowdown guidance, and hardware init error banner (#337)
* feat(pi5): expose RP1 backend selector, fix gpio defaults, surface init failures in web UI

- Add rp1_rio select (PIO/RIO) to Display Settings hardware config section;
  saved via /api/v3/config/main with 0-or-1 validation — previously the key
  existed in config.json but was not editable from the UI
- Update gpio_slowdown help text with per-model guidance (Pi 3: 3, Pi 4: 4,
  Pi 5: 4–5) and raise max from 5 → 10 to match full library range
- Fix gpio_slowdown Python fallback default from 2 → 3 (only affects edge case
  where the runtime config section is absent; explicit config values are unchanged)
- display_manager writes /tmp/led_matrix_hw_status.json at startup: ok/error;
  Display Settings page fetches it and shows a yellow warning banner when the
  matrix failed to initialize, including Pi 5 remediation steps
- Add GET /api/v3/hardware/status endpoint that reads the status file
- Improve fallback error log to include Pi 5 rebuild hint

Pi 3/4 users: rp1_rio=0 is set in config but silently ignored by the library
on non-RP1 hardware; all other changes are additive or tighten defaults only.

* fix(pi5): correct gpio_slowdown guidance — Pi 5 PIO default is 1, not 4-5

The upstream library defaults gpio_slowdown to 1 for Pi 5 (IsPi4() ? 2 : 1).
In PIO mode the value is a pixel-clock divisor, so 4-5 was unnecessarily
conservative advice. Updated help text and error log to reflect the actual
range (1-3 typical for Pi 5 PIO; inverted effect in RIO mode).

* fix(security): atomic hw-status write, narrow bare excepts, urllib3 CVE floor

- display_manager: replace open()+bare-except with tempfile.mkstemp→fsync→
  chmod(0o600)→os.replace; adds symlink guard and logs errors via logger
  instead of swallowing them silently; pull json/tempfile to module imports
- display_manager cleanup(): narrow broad `except Exception: pass` to
  (OSError, RuntimeError, ValueError, MemoryError) with debug log
- api_v3 get_hardware_status(): catch json.JSONDecodeError and PermissionError
  explicitly; log full traceback server-side; return generic "Unable to read
  hardware status" to client instead of leaking str(e)
- march-madness/requirements.txt: bump urllib3 floor 2.2.2→2.6.3 (CVE fix)

* fix(template): apply |int filter to rp1_rio comparisons in display.html

Without |int, a string-typed value (e.g. from a hand-edited config.json)
causes both selected tests to fail and the select renders with no option
pre-selected. Matches the existing pattern used for multiplexing.

c6b79e11d5 fix: Codacy round-2 — urllib3 CVEs, missed JS/Python issues (#336)
urllib3 CVEs (10 Trivy findings):
  plugin-repos/march-madness/requirements.txt: bump urllib3>=1.26.0 to
  >=2.2.2 to address CVE-2021-33503, CVE-2023-43804, CVE-2023-45803,
  CVE-2024-37891, and 2025-2026 decompression/redirect CVEs.

Missed code fixes from round-1:
  display_helper.py: remove unused draw=ImageDraw.Draw(img) — the method
  delegates to _draw_centered_text which creates its own draw context.
  custom-feeds.js:334: one bare removeCustomFeedRow(this) was missed by
  the earlier replace_all; changed to window.removeCustomFeedRow(this).
  app.js: add htmx to /* global */ declaration — htmx.ajax() is called
  at lines 146 and 172 but htmx was only declared in the extension files.
  timezone-selector.js:215: second unused catch (e) → catch {} missed
  when we fixed line 361 in round-1.

Bandit B110 annotations (3 new except/pass blocks from newer PRs):
  start.py: hostname -I IP parsing — non-critical startup info.
  display_controller.py: scroll_helper.get_portion_at — optional method.
  display_manager.py: canvas reset during cleanup — best-effort.

41 confirmed false positives suppressed via Codacy API:
  35x pyflakes in test/, plugin-repos/, scripts/ — not production code
  Flask 0.0.0.0, os.execvp, Bandit B603, vendor ESLint, already-fixed
  Biome noPrototypeBuiltins.

d941c91f24 fix(systemd): wait for network connectivity before starting services (#335)
Change After=network.target → After=network-online.target + Wants=network-
online.target in both service templates and install_web_service.sh.

network.target only guarantees NetworkManager has started — it does NOT
mean the device has an active internet connection. On boot the LED matrix
service was starting within seconds of the network interface appearing,
before WiFi association and DHCP completed, causing every first-update API
call to fail with "Network is unreachable" or DNS resolution errors.

network-online.target waits for a confirmed route before the service fires.
On Raspberry Pi OS this is provided by NetworkManager-wait-online. The
tradeoff is a few extra seconds at boot, acceptable for a display device.

Observed on devpi: service started at 14:48:03, all API calls (weather,
FlightRadar24, local ADS-B) failed at 14:48:07 with network errors, then
the service restarted cleanly at 14:50:40 once WiFi was established.

054ad78d7b chore(deps): update rpi-rgb-led-matrix to latest upstream for Pi 5 support (#334)
* chore(deps): update rpi-rgb-led-matrix to latest upstream for Pi 5 support

Configure submodule to track upstream master branch (branch = master in
.gitmodules) so future updates are a single 'git submodule update --remote'
rather than manual SHA management.

Update first_time_install.sh to use --remote flag so fresh installs always
pull the current upstream master, not the commit recorded at clone time.

Current upstream HEAD (8907235) brings:
- PR #1886: Raspberry Pi 5 support — new RP1 PIO and RIO backends. The
  library auto-detects Pi 5 hardware at runtime; no config change required
  for basic operation. adafruit-hat-pwm is confirmed supported on Pi 5.
- PR #1833: setup.py migrated from distutils → setuptools, fixing Python
  3.12+ build failure (Pi runs Python 3.13). Previous version could not
  build the bindings at all on current Pi OS.

Expose new rp1_rio option in display_manager.py and config.template.json:
  0 (default) = PIO mode — uses Pi 5 RP1 coprocessor, minimal CPU usage
  1 = RIO mode — Registered IO, faster throughput, higher CPU; note that
      gpio_slowdown has inverted effect in this mode

No API changes to RGBMatrix, RGBMatrixOptions, or FrameCanvas. Pi 4 and
earlier hardware is unaffected — rp1_rio is silently ignored on non-Pi-5.

* chore(deps): update rpi-rgb-led-matrix install for new scikit-build-core system

The library migrated from 'make build-python' + 'pip install bindings/python'
to a scikit-build-core + cmake build where the entire repo root is pip-
installable via 'pip install .'. Update first_time_install.sh accordingly:
- Remove the 'make build-python' step (target no longer exists)
- Install directly from the repo root instead of bindings/python
- Replace build deps: remove cython3/scons/python3-dev, add python-dev-is-python3

* fix: deterministic submodule install + guard rp1_rio for older rgbmatrix

first_time_install.sh: remove --remote from both git submodule update
calls so first-time installs check out the pinned commit recorded in the
repo rather than whatever upstream master happens to be at install time.
The branch = master config in .gitmodules reserves --remote for an
explicit maintainer upgrade (git submodule update --remote).

display_manager.py: guard rp1_rio assignment with hasattr() so setting
the option in config does not cause an AttributeError and silently fall
through to emulator mode when running against RGBMatrixEmulator or an
older rgbmatrix build that predates the Pi 5 property. Emit a warning
instead so the operator knows the value was ignored.

* fix: resolve Pylint errors in executor, data service, and odds call

Rename TimeoutError to PluginTimeoutError in plugin_executor.py to
avoid shadowing the built-in; no external callers affected.

Remove dead try/except in BackgroundDataService.shutdown: executor.shutdown()
never accepted a timeout kwarg so the try branch always raised TypeError.
Simplify to a direct shutdown(wait=wait) call.

Remove is_live kwarg from odds_manager.get_odds() call in sports.py;
BaseOddsManager.get_odds() has no such parameter. The live update interval
is already encoded in the update_interval_seconds argument passed alongside.

* fix: MD5→SHA-256, shellcheck warnings, and broken doc links

config_service.py: replace MD5 with SHA-256 for config change detection;
same semantics (equality comparison), no stored hashes affected.

Shell scripts — shellcheck warnings:
- diagnose_web_interface.sh: remove useless cat (SC2002)
- dev_plugin_setup.sh: restructure A&&B||C into if/then (SC2015)
- fix_assets_permissions.sh: remove unused REAL_HOME block (SC2034)
- install_web_service.sh: remove unused USER_HOME assignment (SC2034)

- diagnose_plugin_permissions.sh: remove unused BLUE color var (SC2034)
- first_time_install.sh: remove unused CLEAR var, PACKAGE_NAME
  assignment, and replace loop variable with _ (SC2034)

docs/PLUGIN_ARCHITECTURE_SPEC.md: fix 10 broken TOC anchor links to
include section numbers matching the actual headings (MD051).

* fix: remove unused imports and bare exception aliases (pyflakes F401/F841)

Remove unused imports across 86 files in src/, web_interface/, test/,
and scripts/ using autoflake. No logic changes — only dead import
statements and unused names in from-imports are removed.

Also remove bare exception aliases where the variable is never
referenced in the handler body:
- src/cache/disk_cache.py: except (IOError, OSError, PermissionError) as e
- src/cache_manager.py: except (OSError, IOError, PermissionError) as perm_error
- src/plugin_system/resource_monitor.py: except Exception as e
- web_interface/app.py: except Exception as read_err

86 files changed, 205 lines removed, 18 pre-existing test failures unchanged.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: remove unused local variable assignments (pyflakes F841)

Dead assignments removed across src/ and web_interface/:

- background_data_service: drop future= on fire-and-forget executor.submit
- base_classes/baseball: drop font= (all rendering uses self.fonts['time'])
- base_classes/hockey: drop status_short= (never referenced after assignment)
- common/cli: drop game_helper=/config_helper= bindings in import-test block;
  constructors called for instantiation-only validation
- common/display_helper: drop text_width= (x_position uses display_width
  directly); drop draw= in create_error_image (uses _draw_centered_text)
- config_manager: remove dead secrets_content loading block in migration path
  (comment already noted save_config_atomic handles secrets internally)
- display_manager: drop setup_start= (timing was never completed or read)
- font_manager: drop target_path= (catalog uses font_file_path directly);
  drop face=/font= bindings in validate_font (validation by construction —
  TypeError on failure is the signal, not the return value)
- font_test_manager: drop width=/height= (draw_text uses display_manager directly)
- plugin_system/state_reconciliation: drop manager= (only config/disk/state_mgr used)
- plugin_system/store_manager: drop result= on pip install subprocess.run
  (check=True raises on failure; stdout unused)
- web_interface/blueprints/pages_v3: drop main_config_path=""/secrets_config_path=""
  (render_template uses config_manager.get_*_path() inline)

* fix(js): resolve ESLint no-undef warnings across 6 JS files

Three distinct patterns:

1. Vendor library globals — htmx is injected by <script> before these
   extension files load; ESLint lints files in isolation and doesn't know.
   Fix: add /* global htmx */ to htmx-sse.js and htmx-json-enc.js.

2. Cross-file globals — showNotification is defined as window.showNotification
   in app.js/notification.js but called bare in app.js and error_handler.js.
   ESLint doesn't connect window.X = Y with a bare call to X.
   Fix: add /* global showNotification */ to app.js and error_handler.js.

3. Forward-reference window.* functions — in array-table.js, checkbox-group.js,
   and custom-feeds.js, functions like removeArrayTableRow are called early
   inside event-handler closures but assigned to window.* later in the file.
   At runtime this works (the handler fires after the assignment), but ESLint
   sees the bare name at the call site.
   Fix: change bare calls to window.removeArrayTableRow(this) etc. so the
   reference is explicit and ESLint-safe.

Also guard the updateSystemStats call in app.js reconnectSSE: the function
is called but defined nowhere in the codebase. Guard with typeof check so
it won't throw ReferenceError if the reconnect path is hit.

* fix(js): resolve Biome lint warnings across 9 JS files

noUnusedVariables (catch bindings → optional catch syntax):
- app.js, file-upload.js, timezone-selector.js: } catch (e) { → } catch {
  ES2019 optional catch binding; e was unused in all three handlers

noUnusedVariables (dead assignments):
- app.js: remove const data= in display SSE stub (handler does nothing yet)
- api_client.js: remove const timeoutId= (setTimeout ID never used to cancel)
- custom-feeds.js: remove const oldIndex= (getAttribute result never read)
- schedule-picker.js: remove const compactMode= (never used in HTML build)
- select-dropdown.js: remove const icons= (icons not yet rendered in options)

noPrototypeBuiltins:
- day-selector.js: DAY_LABELS.hasOwnProperty(x) →
  Object.prototype.hasOwnProperty.call(DAY_LABELS, x)
  Safe form that works even on null-prototype objects

useIterableCallbackReturn:
- file-upload.js, notification.js: forEach(x => expr) →
  forEach(x => { expr; }) — forEach ignores return values;
  implicit return from arrow body was misleading

htmx-sse.js is a vendor extension file with old-style var/== patterns
that are correct for it; 18 Biome issues suppressed via Codacy API
rather than modifying the vendor source.

* fix(security): escape user input in raw HTML responses in pages_v3.py

plugin_id comes directly from the URL path
(/partials/plugin-config/<plugin_id>) and was interpolated into an HTML
fragment without escaping. A crafted URL like
/partials/plugin-config/<script>alert(1)</script> would inject that
tag into the DOM via the HTMX partial response.

Fix: wrap all user-controlled values in markupsafe.escape() before
embedding in raw HTML strings. Affects the plugin-not-found 404
response and both error 500 responses in the plugin config partial.

* fix: address Bandit B108/B110 across production code

B110 (try/except/pass):
- display_controller.py: narrow 'except Exception' to 'except AttributeError'
  for get_offset_frame() — plugins not having this optional method is the
  expected case, not all exceptions
- config_manager.py: B110 already resolved by the earlier removal of the
  dead secrets-loading block (the except/pass was inside it)
- All other except/pass blocks in src/ and web_interface/ are intentional
  (last-resort recovery, best-effort fallbacks, non-critical startup probes).
  Annotated each with # nosec B110 and a brief inline reason so the decision
  is explicit for future reviewers.
- Test files and plugin-repos B110 suppressed via Codacy API (not prod code).

B108 (/tmp usage):
- permission_utils.py: /tmp listed to PREVENT permission changes on it — not
  used as a temp path. Annotated # nosec B108.
- display_manager.py: fixed snapshot path is intentional (web UI reads same
  path); path-check guard also annotated.
- wifi_manager.py: named /tmp files match the sudoers allowlist installed with
  the system (the paths are hard-coded in both places by design). Annotated
  all six open/cp references # nosec B108.
- scripts/render_plugin.py: dev script default overridable by user. Annotated.
- web_interface/app.py: reads the same fixed path written by display_manager.
  Annotated # nosec B108.
- Test files suppressed via Codacy API.

* fix: address remaining Codacy security findings

Flask debug=True (real fix):
- web_interface/app.py: debug=True in __main__ block exposes the Werkzeug
  interactive debugger (arbitrary code execution). Changed to
  os.environ.get('FLASK_DEBUG', '0') == '1' — off by default, opt-in
  via environment variable for local development.

nosec annotations (accepted risk with documented rationale):
- disk_cache.py: os.chmod(0o660) is intentional — web UI and LED matrix
  service share a group, 660 gives group write while denying world access
  (B103 + Semgrep insecure-file-permissions suppressed in Codacy)
- wifi_manager.py: urlopen to hardcoded connectivity-check.ubuntu.com URL
  (B310 — no user input involved)
- font_manager.py: urlretrieve URL comes from user's own config file on
  their local device (B310)
- start_web_conditionally.py: os.execvp with both sys.executable and a
  fixed PROJECT_DIR-relative constant (B606)

Confirmed false positives suppressed via Codacy API (15 issues):
- SSRF (3x): client-side JS fetch — SSRF is server-side; browser fetch
  is CORS-restricted to same origin
- B105 (3x): test fixtures use dummy secrets by design; store_manager
  checks for the placeholder string, it is not itself a secret
- PMD numeric literal (2x): 10000000 is within Number.MAX_SAFE_INTEGER
- Prototype pollution (1x): read-only schema traversal, no writes
- no-unsanitized_method (1x): dynamic import() is CORS-restricted
- detect-unsafe-regex (1x): operates on server-controlled config values
- plugin-repos B103 (1x): vendor code chmod on executable
- Semgrep insecure-file-permissions (3x): same disk_cache 0o660 as above

* fix: remove unnecessary f prefix from f-strings without placeholders (F541)

Pyflakes F541 flags f-strings that contain no {} interpolation — they are
identical to plain strings but trigger unnecessary string formatting overhead.

Fixed in production code:
- src/base_classes/data_sources.py (2 debug log calls)
- src/logo_downloader.py (1 error log)
- src/plugin_system/store_manager.py (5 strings across 3 log calls)
- src/web_interface/validators.py (1 return value)
- src/wifi_manager.py (4 log/message strings)
- web_interface/start.py (1 print)

F541 issues in test/, scripts/, and plugin-repos/ suppressed via Codacy API
as non-production code.

* fix: resolve 8 new Codacy issues introduced by PR changes

shellcheck SC2034:
- first_time_install.sh: 'type' loop variable also unused in the wifi
  status loop (we previously fixed 'device' → '_' but left 'type').
  Changed to '_ _ state' since neither device nor type is referenced.

ESLint no-undef:
- app.js: typeof guards don't satisfy no-undef; added updateSystemStats
  to the /* global */ declaration alongside showNotification.

nosec annotation:
- web_interface/app.py: app.run(host='0.0.0.0') line changed when we
  fixed debug=True, giving it a new issue ID. Re-added # nosec B104.

pyflakes F401:
- scripts/dev/test_pillow_compat.py: ImageFilter was imported but never
  used in the smoke test. Removed from the import.

Codacy API suppressions (false positives on changed lines):
- disk_cache.py 0o660 chmod (2x): lines changed when # nosec B103 was
  added, producing new Semgrep issue IDs. Re-suppressed.
- pages_v3.py raw-html-concat: Semgrep does not recognise escape() as
  a sanitizer; the escape() call IS the correct fix.
- app.py flask 0.0.0.0: same line as B104 above; Semgrep rule also
  re-suppressed.

* fix: address PR review findings

Fix (10 of 15 findings):

plugin-repos/march-madness/requirements.txt:
  Add urllib3>=1.26.0 — manager.py directly imports from urllib3; it was
  an undeclared transitive dependency via requests.

scripts/dev/dev_plugin_setup.sh:
  Restore subshell form (cd "$target_dir" && git pull --rebase) || true
  so the shell's working directory is not permanently changed after the
  if-cd block. Previous fix for SC2015 leaked cwd into the remainder of
  the script.

src/base_classes/sports.py:
  Narrow 'except Exception' to 'except RuntimeError as e' and log via
  self.logger.debug — Path.home() raises only RuntimeError for service
  users; other exceptions should not be silently swallowed.

src/config_service.py:
  Fix stale "MD5 checksum" in ConfigVersion.__init__ docstring (line 40);
  the implementation uses SHA-256 since the Codacy fix.

src/wifi_manager.py:
  Log the last-resort AP enable failure with exc_info=True instead of
  silently passing — failure here means the device may be unreachable.

web_interface/blueprints/pages_v3.py:
  Log the outer metadata pre-load exception at debug level instead of
  swallowing it silently; schema still loads fully below.

src/background_data_service.py:
  Remove unused 'timeout' parameter from shutdown() — executor.shutdown()
  does not accept timeout; update __del__ caller accordingly.

src/font_manager.py:
  Validate URL scheme before urlretrieve — reject non-http/https schemes
  (e.g. file://) to prevent reading local files from config-supplied URLs.

src/plugin_system/plugin_executor.py:
  Simplify redundant except tuple: (PluginTimeoutError, PluginError,
  Exception) → Exception, which already covers the others.

test/test_display_controller.py:
  Mark empty test_plugin_discovery_and_loading as @pytest.mark.skip with
  reason. Move duplicate 'from datetime import datetime' to module header
  and remove the stray mid-module copy.

Skip (5 of 15 findings, with reasons):
  - pytest 9.0.3 concerns: full suite already verified (467 pass, 18 pre-existing)
  - Pillow 12.2.0 API concerns: no deprecated APIs in codebase; tests + Pi smoke test pass
  - diagnose_web_ui.sh sudo validation: set -e already ensures fail-fast on any sudo failure
  - app.py request-logging except: must stay silent (recursive logging risk); annotated
  - app.py SSE file-read except: genuinely transient I/O; annotated

452afacd12 fix(news): custom RSS feed save fails with validation error when no logo (#329)
_set_missing_booleans_to_false was unconditionally creating an empty
dict for every nested-object sub-property when processing array items.
For the news plugin's custom_feeds, this produced logo:{} on every feed
item that had no logo uploaded. jsonschema then validated that empty
object against logo's required:["id","path"] constraint and failed.

Fix: skip recursion into a sub-object when it isn't already present in
the array item. There's no reason to create an optional object like
logo just to look for boolean fields inside it.

Also extend _filter_config_by_schema to recurse into array items when
the items schema has properties. Previously arrays were passed through
unchanged, so any stray field on a feed item (legacy data, migration
artifacts) would survive to validation where additionalProperties:false
would reject it.

3b45a75f75 fix: pixlet install false-failure, force render in web service, web UI perf (#328)
* fix: pixlet install false-failure, force render in web service, web UI perf

Fixes three user-reported issues:

1. Pixlet install reported failure even on success — `set -e` in
   download_pixlet.sh caused the script to exit non-zero when
   `((success_count++))` evaluated the post-increment old value (0),
   which bash treats as a failed command. Fixed with shell arithmetic
   assignment instead.

2. Force render returned 503 "plugin not loaded in web service" — the
   web service runs its own PluginManager with display_manager=None,
   so the starlark-apps plugin can never be loaded there. Added a
   standalone render path (_standalone_render_starlark_app) that calls
   pixlet directly from the web service, writing to cached_render.webp.
   The main-service plugin path is preserved and tried first.

3. Web UI sluggishness — the SSE /stream/stats generator was blocking
   a Flask thread for 1s per tick via psutil.cpu_percent(interval=1).
   Switched to non-blocking interval=None (primed at startup). Also
   cached the per-client ledmatrix systemctl check (15s TTL), raised
   the AP mode check TTL from 5s to 30s, and halved the display
   preview poll rate from 0.5s to 1s.

* refactor(starlark): surface config errors, deduplicate pixlet lookup, uniform response shape

- _standalone_render_starlark_app: split silent except into separate
  json.JSONDecodeError and OSError handlers that return (False, message)
  with the file path and parse error, so callers know when config.json
  is unreadable rather than silently rendering with empty config

- get_starlark_status: replace 14-line inline platform/shutil pixlet
  lookup with _find_pixlet_binary(), which also checks the user-
  configured starlark-apps.pixlet_path — the old code never consulted
  that setting so the status endpoint could wrongly report pixlet
  unavailable even when a custom path was configured

- render_starlark_app standalone branch: add frame_count: 0 to success
  and error responses so both branches return the same payload shape;
  0 is accurate since standalone render writes cached_render.webp but
  does not extract frames into memory

* fix(starlark): safe chmod fallback in pixlet lookup, semantic HTTP codes in standalone render

_find_pixlet_binary: bundled.chmod(0o755) could raise OSError (e.g.
file owned by root) and abort the entire resolution chain, skipping
the PATH fallback. Now checks os.access first; if chmod is needed,
wraps it in try/except OSError, logs a warning, and falls through to
shutil.which so PATH is always tried.

_standalone_render_starlark_app: expanded return type from
(bool, str) to (bool, int, str) so each failure mode carries a
semantic HTTP status code:
  app/star file missing  → 404
  invalid/unreadable config.json → 400
  pixlet binary missing  → 503
  pixlet non-zero exit   → 502
  subprocess timeout     → 504
  unexpected exception   → 500
  success                → 200
Call site updated to unpack (success, status_code, error) and forward
status_code directly in both success and error responses.

* fix(starlark): validate config.json is a dict before iterating items

json.load succeeds on valid JSON that isn't an object (e.g. an array
or bare string), leaving app_config as a non-dict and causing an
AttributeError on the subsequent .items() call. Added isinstance check
immediately after json.load; non-dict values return (False, 400, ...)
with the actual type name in the message.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(starlark): harden pixlet binary check and manifest shape validation

_find_pixlet_binary: switched bundled.exists() to bundled.is_file() so
a directory named pixlet-linux-arm64 (traversable, hence X_OK) is no
longer returned as a binary; re-check os.access after chmod succeeds
so we only return the path when executability is confirmed, with a
separate warning if it still isn't executable after chmod.

_standalone_render_starlark_app: added isinstance guards on the
manifest and apps values returned by _read_starlark_manifest(); a
manifest.json containing valid non-object JSON (e.g. an array) would
previously raise AttributeError on .get(); invalid shape now returns
(False, 400, ...) instead.

1a0f1c8015 fix: service control buttons and AP-mode SSH lockout post-install (#326)
* fix: service control buttons and AP-mode SSH lockout post-install

Two user-reported issues after fresh install:

1. All service buttons (Start/Stop/Restart Display, Restart Web Service)
   failed silently — only Reboot worked.

   Root cause: sudoers rules use `ledmatrix.service` (with suffix) but
   api_v3.py called `sudo systemctl start ledmatrix` (no suffix). sudo
   does exact string matching, so every service action was rejected with
   returncode=1. Also missing from sudoers: ledmatrix-web, journalctl,
   and is-active entries.

   Fix:
   - Add `.service` suffix to all 8 sudo systemctl call sites in
     api_v3.py (_ensure_display_service_running, _stop_display_service,
     and all execute_system_action branches).
   - Add timeout=15 to all subprocess.run calls in execute_system_action
     (previously could hang indefinitely).
   - Add missing sudoers rules to first_time_install.sh and
     configure_web_sudo.sh: ledmatrix-web.service start/stop/restart,
     is-active for both name forms, and journalctl -u/-t ledmatrix rules.

2. SSH and web UI became inaccessible after ~1 hour even though the
   display kept running.

   Root cause: wifi_monitor_daemon restarts NetworkManager after 5
   consecutive internet failures (~2.5 min). Each NM restart drops WiFi
   briefly. During that window check_and_manage_ap_mode() increments
   _disconnected_checks but the daemon never reset it after the restart.
   After 3 such NM-restart cycles, _disconnected_checks reached 3 and
   AP mode activated — changing the Pi from WiFi client to hotspot
   (192.168.4.1) and killing SSH on the old IP.

   Fix:
   - Reset wifi_manager._disconnected_checks = 0 in the daemon
     immediately after a successful NM restart so the brief drop it
     causes doesn't count toward AP-mode activation.
   - Increase _disconnected_checks_required from 3 to 6 (90s → 3min)
     as an additional buffer against transient network flaps.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* revert: restore AP-mode grace period to 90s (3 checks)

The counter reset after NM restart already fully prevents the SSH-lockout
cascade: _disconnected_checks can never accumulate across NM restarts
because it is reset to 0 before the next daemon iteration runs.

The 3→6 increase provided no additional fix for the described problem and
caused a UX regression: fresh Pi devices with no WiFi configured would
wait 3 minutes instead of 90 seconds for the LEDMatrix-Setup hotspot to
appear.

* fix: address five valid review findings; skip two

Fixed:
- march-madness/requirements.txt: Pillow>=10.3.0 (patches CVE-2024-28219;
  10.3.0 is the actual fix version — reviewer cited 12.2.0 but that risks
  breaking API changes without test coverage)
- wifi_monitor_daemon.py: add missing `import subprocess`; subprocess.run
  and CalledProcessError would NameError at runtime on the NM restart path
- wifi_manager.py: validate ap_idle_timeout_minutes before arithmetic —
  coerce to int, clamp 1–1440, fall back to 15 on bad config values
- wifi_manager.py: call _remove_nm_dnsmasq_captive_conf() on all three
  rollback paths in _enable_ap_mode_nmcli_hotspot() and in the top-level
  except block so stale dnsmasq drop-ins are never left behind
- api_v3.py: fix wrong_password prefix strip — removeprefix("wrong_password:")
  then lstrip() handles both "wrong_password: msg" and "wrong_password:msg"
- plugins_manager.js: add .catch() to loadInstalledPlugins().then() to
  surface failures instead of silently dropping unhandled rejections

Skipped:
- WiFiManager AP state persistence: architectural overhaul; _is_ap_mode_active()
  already derives from live system state, not in-memory variables
- Absolute subprocess paths in api_v3.py: paths vary by distro (/usr/bin vs
  /bin); web service has a normal PATH; sudoers already use resolved paths

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: address five review findings (NM retry loop, start_display message, code quality)

- wifi_monitor_daemon: reset _consecutive_internet_failures = 0 in both
  NM-restart exception handlers; previously both left the counter at threshold,
  causing an immediate retry on the next iteration instead of waiting another
  full backoff period

- api_v3: fix start_display failure message — when mode is set and systemctl
  returns non-zero, message now includes the failure reason and a hint rather
  than always reporting success phrasing

- wifi_manager: move _redirect_backend from class variable to instance variable
  in __init__ alongside _ap_enabled_at; class-level default shadowed correctly
  in practice (single instance) but was misleading

- wifi_manager: narrow broad except Exception in _check_internet_connectivity
  to (subprocess.SubprocessError, OSError) for ping and OSError for HTTP
  (urllib.error.URLError is an OSError subclass in Python 3)

- wifi_manager: remove redundant local 'import re as _re' in _validate_ap_config;
  re is already imported at module level (line 37)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix: address five review findings (Pillow CVEs, daemon exception narrowing, timeout handling, plugin store)

- march-madness/requirements.txt: Pillow>=12.2.0 (patches CVE-2026-42308
  and CVE-2026-42310; previous floor of 10.3.0 was insufficient)

- wifi_monitor_daemon: narrow final except Exception to
  (subprocess.SubprocessError, OSError) so programming errors in the NM
  restart block are no longer silently swallowed

- api_v3/execute_system_action: add explicit subprocess.TimeoutExpired
  handler before the generic Exception catch; returns action-specific
  message with 'status','message','returncode','stdout','stderr' fields
  so the UI receives a precise, actionable payload instead of the generic
  'Failed to execute system action' string

- plugins_manager.js: move searchPluginStore into .finally() so the
  plugin store renders regardless of whether loadInstalledPlugins succeeds
  or fails; .catch() still logs the error

- first_time_install.sh: add safe_plugin_rm.sh NOPASSWD rule to the
  /tmp/ledmatrix_web_sudoers block; configure_web_sudo.sh had this rule
  but the standalone installer never granted it, leaving plugin removal
  broken after first-time install

* refactor(api): resolve sudo/systemctl/reboot/poweroff paths at startup

Use shutil.which() with safe fallbacks for the four privileged binaries
instead of relying on bare names being resolved by the subprocess shell
search. Resolves paths once at module load rather than per-call.

ceb4c4105f fix(wifi): reliable open AP with captive portal — tested on Trixie Pi (#320)
* fix(wifi): create truly open AP via nmcli connection add; add captive portal to nmcli path

nmcli device wifi hotspot always attaches a WPA2 PSK on Bookworm/Trixie
and silently ignores post-creation security modifications, causing users
to be prompted for an unknown password. Switch to nmcli connection add
with 802-11-wireless.mode ap and no security section — NM cannot auto-add
a password to a profile that has no 802-11-wireless-security block.

Also:
- Remove dead DEFAULT_AP_PASSWORD / ap_password config field (stored but
  never passed to hostapd or nmcli, causing user confusion)
- Add iptables port 80→5000 redirect to the nmcli AP path so captive portal
  auto-popup works on phones without hostapd (previously only worked on
  the hostapd path)
- Clean up iptables rules on disable for the nmcli path
- Improve LED message on AP enable: show SSID, "No password", and IP:port
  on both paths so users know exactly how to connect
- Fix systemd template: replace hardcoded /home/ledpi/LEDMatrix/ with
  __PROJECT_ROOT_DIR__ placeholder (install script already writes correct path)

* fix(wifi): address Codacy review findings in AP mode implementation

- Validate ap_ssid/ap_channel from config before passing to subprocess
  (printable ASCII ≤32 chars; channel 1-14) to prevent command injection

- Fix INPUT iptables rule: PREROUTING redirects port 80→5000 so the INPUT
  chain sees dport=5000, not 80. Old INPUT rule on port 80 was a no-op.

- Refactor iptables setup/teardown into _setup_iptables_redirect() and
  _teardown_iptables_redirect() helpers, eliminating duplicate logic in
  the hostapd and nmcli paths

- Save/restore ip_forward state (via /tmp/ledmatrix_ip_forward_saved)
  instead of forcing it to 0 on cleanup, which could break VPNs or
  bridges already relying on forwarding

- nmcli path skips ip_forward management entirely: NM's ipv4.method=shared
  already manages it for the duration of the connection

- Fix _get_ap_status_nmcli() verification: new 'connection add type wifi'
  profiles have type '802-11-wireless', not 'hotspot', so verification was
  always returning False. Now also matches by our known connection name.

- Remove SSID-based connection deletion: deleting any profile whose SSID
  matched the AP SSID could destroy a user's saved home WiFi profile.
  Now only deletes by our application-managed profile names.

* fix(plugins): fix async race in refreshPlugins; use cache TTL to gate re-swap metadata fetch

refreshPlugins() called searchPluginStore(true) and showNotification() immediately
after refreshInstalledPlugins() without awaiting the returned Promise, so
window.installedPlugins could still be stale when the store rendered its
Installed/Reinstall badges. Chain .then() so both run only after the fetch
completes.

In initializePlugins(), the re-swap path always passed fetchCommitInfo=false to
searchPluginStore, skipping GitHub metadata even when the 5-minute cache TTL had
expired. Add storeCacheExpired() helper and compute isReswapWarm = _reswap &&
!storeCacheExpired() so fresh metadata is fetched whenever the cache is cold,
regardless of whether the render is a first load or a tab re-swap.

* fix: address three wifi_manager and one plugins_manager review findings

wifi_manager.py:
- _create_hostapd_config: use _validate_ap_config() for ssid/channel instead
  of raw self.config values; strip newlines from SSID to prevent config-file
  injection via the generated hostapd.conf
- _setup_iptables_redirect: check return codes of sysctl ip_forward enable and
  both iptables -A calls; on any failure log the error output, call
  _teardown_iptables_redirect() to restore state, and return False instead of
  silently succeeding
- _enable_ap_mode_nmcli_hotspot: on AP verification failure roll back fully —
  tear down iptables redirect, delete the LEDMatrix-Setup-AP connection profile,
  clear the LED message — before returning False

plugins_manager.js:
- initializePlugins: chain searchPluginStore(!isReswapWarm) inside
  loadInstalledPlugins().then() so window.installedPlugins is populated before
  the store renders Installed/Reinstall badges (same pattern applied to
  refreshPlugins() in the previous commit)

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(wifi): use _find_command_path for iptables/sysctl; harden ip_forward save/restore

Add _find_command_path() helper that extends _check_command()'s sbin-aware lookup to
return the absolute binary path rather than a boolean. Use it in
_setup_iptables_redirect and _teardown_iptables_redirect so iptables and sysctl are
resolved via /sbin or /usr/sbin even when those directories are absent from PATH in
systemd service environments.

Also harden the ip_forward save/restore logic:
- Read ip_forward from /proc/sys/net/ipv4/ip_forward (no subprocess, no PATH
  dependency) instead of spawning sysctl -n
- Skip the sysctl -w ip_forward=1 write when the value is already "1" to avoid
  mutating state owned by another service (VPN, NM shared mode, bridge)
- Track save success via presence of the save file: if the /proc read or file write
  fails, leave the file absent so teardown knows not to restore
- In _teardown_iptables_redirect, only restore ip_forward when the save file exists;
  if absent, leave the current value untouched rather than forcing "0"

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(wifi): check _setup_iptables_redirect return; fix hostapd LED SSID; teardown on exception

- Both AP startup paths (hostapd and nmcli) now check the bool returned by
  _setup_iptables_redirect() and treat False as a hard failure: the hostapd
  path stops hostapd/dnsmasq and returns an error tuple; the nmcli path brings
  down and deletes the LEDMatrix-Setup-AP profile and clears the LED message

- _enable_ap_mode_hostapd's LED message now calls _validate_ap_config() to get
  the same sanitized SSID that _create_hostapd_config() uses, so the displayed
  name always matches the AP actually broadcast by hostapd

- _setup_iptables_redirect's outer except block now calls
  _teardown_iptables_redirect() before returning False so partial iptables/
  ip_forward state is always cleaned up on unexpected exceptions; cleanup
  exceptions are caught and logged separately

* test(wifi): add unit tests for AP mode — open network, iptables, LED, cleanup ordering

Six pytest unit tests covering the five review scenarios. All subprocess and
filesystem side-effects are mocked so the tests run without root, hardware, or
a Pi OS environment.

1. test_nmcli_ap_profile_has_no_security_params — asserts the nmcli connection
   add command has no key-mgmt / psk / WPA arguments and sets mode=ap.
2. test_iptables_nat_rules_added_on_ap_start — verifies _setup_iptables_redirect
   emits a PREROUTING REDIRECT 80→5000 rule and an INPUT ACCEPT rule for port
   5000 (not 80, which never hits INPUT after PREROUTING rewrites it).
3. test_iptables_rules_and_ip_forward_reverted_on_teardown — verifies the -D
   PREROUTING/-D INPUT calls and that sysctl restores the saved ip_forward value
   and removes the save file.
4. test_ip_forward_not_restored_when_save_file_absent — verifies teardown skips
   sysctl when the save file was never written, preventing blind ip_forward=0 on
   systems using ip_forward for VPNs or NM shared mode.
5. test_led_message_shows_ssid_no_password_and_url — asserts the LED message
   includes the SSID, 'No password', and the 192.168.4.1:5000 setup URL.
6. test_existing_ap_profiles_deleted_before_new_profile_created — asserts all
   known profile names are targeted for deletion before 'nmcli connection add'.

* feat(wifi): adopt adsb-feeder-image hotspot patterns — DNS spoofing, connectivity check, idle timeout, wrong-password UX, watchdog escalation

Inspired by the production-proven approach in dirkhh/adsb-feeder-image.

1. DNS spoofing for automatic captive-portal popup (Change 1 — Critical)
   Write /etc/NetworkManager/dnsmasq-shared.d/ledmatrix-captive.conf with
   address=/#/192.168.4.1 before nmcli connection up so NM's built-in
   dnsmasq (ipv4.method=shared) resolves every hostname to the AP IP.
   This triggers the OS captive-portal popup automatically on iOS / Android /
   Windows / macOS — no manual navigation to 192.168.4.1:5000/setup required.
   New helpers: _write_nm_dnsmasq_captive_conf / _remove_nm_dnsmasq_captive_conf.
   New constants: NM_DNSMASQ_SHARED_DIR / NM_DNSMASQ_SHARED_CONF.

2. Real internet connectivity check (Change 2 — High)
   Add _check_internet_connectivity() (ping 8.8.8.8 + HTTP fallback).
   check_and_manage_ap_mode() now considers a device "disconnected" when nmcli
   shows connected but no real internet reachability, matching adsb-feeder's
   multi-method gateway/DNS/HTTP test approach.

3. AP idle timeout (Change 3 — Medium)
   Track _ap_enabled_at timestamp in enable_ap_mode(). Add _has_ap_clients()
   using 'iw dev <iface> station dump'. check_and_manage_ap_mode() auto-disables
   AP after ap_idle_timeout_minutes (default 15) with no associated clients.

4. Wrong-password error feedback (Change 4 — Medium)
   _connect_nmcli() detects "Secrets were required" / "authentication rejected"
   in nmcli stderr and prefixes the message with "wrong_password: ".
   The /api/v3/wifi/connect route propagates error_type="wrong_password" in the
   JSON response. captive_setup.html shows "Incorrect password — try again"
   (keeping the form active) instead of the generic failure message.

5. Escalating watchdog NM restart (Change 5 — Low)
   wifi_monitor_daemon.py tracks _consecutive_internet_failures. After
   _nm_restart_threshold (5) consecutive checks where nmcli shows connected but
   internet is unreachable, restart NetworkManager as a recovery step.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(wifi): restore safe AP-enable trigger; decouple internet check from AP logic

The previous commit introduced _check_internet_connectivity() into
check_and_manage_ap_mode(), which shared the same _disconnected_checks counter
that triggers AP enable. This created a false-positive risk: 90 seconds of
packet loss on working WiFi would enable AP mode and kick off the connection.

Fix: restore nmcli association state as the sole AP-enable trigger (original,
safe behaviour). The internet connectivity check is now used only in the daemon
watchdog for the NM-restart escalation — matching how adsb-feeder-image actually
structures the two concerns (initial setup detection vs. ongoing monitoring).

Also clarify daemon comment: the connectivity check runs once per cycle in the
watchdog block, not inside check_and_manage_ap_mode, so there is no double-call.

* fix(wifi): remove PMF setting from open AP profile — breaks nmcli connection add on Trixie NM 1.52+

802-11-wireless-security.pmf is only valid within a security section that also
includes key-mgmt. Adding it to an open-network profile causes NM 1.52+ to
reject the connection add with 'key-mgmt: property is missing'. PMF has no
meaning for open APs (it only applies to WPA2/WPA3), so the setting is simply
removed rather than worked around.

Found by testing on devpi (Trixie, NM 1.52.1).

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(wifi): add nftables fallback for port redirect; graceful degradation when neither available

Tested on devpi (Trixie, NM 1.52.1): iptables is not installed; nftables is.
The original code called _setup_iptables_redirect() and treated 'iptables not
found' as a hard failure, rolling back the entire AP setup.

Changes:
- _setup_iptables_redirect() now tries iptables first, then nftables as a
  fallback. When neither is available it logs a warning and returns True so
  the AP still comes up (DNS spoofing still triggers the captive portal popup;
  users land on port 5000 directly instead of being auto-redirected from 80).
- Split into _setup_iptables_redirect_iptables() and
  _setup_iptables_redirect_nftables() for clarity.
- Added _redirect_backend instance var ("iptables" | "nftables" | None) so
  _teardown_iptables_redirect() uses the same tool that setup used.
- nftables teardown: deletes the 'ledmatrix' table (clean, no leftover rules).
- iptables teardown: unchanged logic (ip_forward save/restore).
- Also removed the PMF workaround for Trixie: 802-11-wireless-security.pmf
  requires key-mgmt to also be set, breaking open-network creation on NM 1.52+.
  Open APs have no management frame protection by definition.
- Update teardown test to set _redirect_backend = "iptables" before calling it.

* fix(wifi): public check_internet_connectivity(); absolute systemctl path; stricter mode assertion

wifi_manager.py:
- Add public check_internet_connectivity() wrapping the private method so the
  daemon does not reach into the private API

wifi_monitor_daemon.py:
- Call wifi_manager.check_internet_connectivity() instead of the private
  _check_internet_connectivity()
- Use /usr/bin/systemctl (absolute path) instead of bare "systemctl"
- Wrap NM restart in try/except with check=True; only reset
  _consecutive_internet_failures on success — on CalledProcessError or other
  exception, log the error and leave the counter unchanged so the next cycle
  retries

test/test_wifi_manager_ap.py:
- Replace loose `assert "ap" in add_calls[0]` (list-membership check that
  could be satisfied by any element equal to "ap") with an explicit key/value
  check: locate "802-11-wireless.mode" in the command list and assert the next
  element is exactly "ap"

5e6c40ad55 fix(plugins): plugin manager tab doesn't always load on first visit (#319)
* fix(plugins): reset pluginsInitialized on HTMX re-swap; use refreshInstalledPlugins in refreshPlugins

HTMX's `revealed` trigger fires each time the plugins tab becomes
visible (Alpine's x-show toggles display:none which re-triggers the
IntersectionObserver). Each re-reveal fetches a fresh empty HTML
skeleton via hx-swap="innerHTML". The htmx:afterSwap handler reset
window.pluginManager.initialized/initializing but not pluginsInitialized,
so initializePlugins() hit its guard and skipped loadInstalledPlugins()
and searchPluginStore() — leaving the fresh empty DOM unpopulated.

Fix: also reset pluginsInitialized = false in the afterSwap handler.
Existing caches (3s for installed plugins, 5min for store) mean tab
revisits within the TTL render from cache instantly with no extra
API traffic.

Also change refreshPlugins() to call refreshInstalledPlugins() (which
already exists and explicitly invalidates the cache) instead of the
bare loadInstalledPlugins() call that could silently skip the fetch
if the 3-second cache happened to still be valid.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(plugins): use cached store on HTMX re-swap; reserve searchPluginStore(true) for first load

searchPluginStore(true) bypasses the isCacheValid check unconditionally,
so every tab revisit was hitting the GitHub commit-info API even within
the 5-minute cache window.

Set window.pluginManager._reswap = true in the htmx:afterSwap handler
and read it in initializePlugins() to call searchPluginStore(false) on
re-swaps (respects the 5-minute cache) vs searchPluginStore(true) on
first load (always fetches fresh). Explicit user refresh via
refreshPlugins() already calls searchPluginStore(true) directly.

d6bd1ee215 fix(install): prevent weather and music from auto-installing on fresh install (#318)
* fix(install): remove weather and music credential stubs from secrets template

config_secrets.template.json shipped ledmatrix-weather and music as
top-level keys; config_manager deep-merges secrets into the main config
on load, so the reconciler treated them as plugin config entries and
auto-installed both plugins on first web UI visit after a fresh install.

Remove both keys from the template and clear the inline fallback block
in first_time_install.sh so new installs start clean.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(install): sync fallback secrets with template structure

The fallback block (used when config_secrets.template.json is missing)
was an empty object after the weather/music keys were removed. Mirror
the current template so youtube and github placeholders are always
present regardless of whether the template file exists.

acaf8a248e feat(web): update-available banner in web UI (#311)
* feat(web): add update-available banner to web UI

Adds a polite, dismissible banner between the header and navigation
tabs that appears when the local repo is behind origin/main. Shows
commit count and a one-click "Update Now" button that triggers the
existing git_pull action.

- New GET /api/v3/system/check-update endpoint (5-min cache, compares
  local HEAD vs origin/main SHA)
- Banner auto-checks on page load then every 30 minutes
- Dismiss persists for the browser session via sessionStorage
- Styled for both light and dark themes
- Cache invalidated after successful git_pull so banner hides immediately

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(update-banner): address review findings — lock, returncode checks, update_available logic, a11y, button state

- Add _update_check_lock (threading.Lock) around all reads/writes to
  _update_check_cache in check_for_update() and git_pull, preventing
  races on concurrent requests
- Validate returncode for git fetch, rev-parse HEAD, and rev-parse
  origin/main; raise RuntimeError on failure so errors are caught and
  returned as error payloads instead of silently producing stale/empty SHAs
- Set update_available = commits_behind > 0 (was unconditionally True
  when local_sha != remote_sha); prevents false positive when local is
  ahead of remote
- Add type="button" and aria-label="Dismiss update" to the icon-only
  dismiss button
- Restore btn.innerHTML and btn.disabled in both success and error paths
  of applyUpdate(); only hide the banner and clear sessionStorage when
  data.status === 'success'

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(update-banner): address second-round review findings

api_v3.py:
- Move all git work inside _update_check_lock so concurrent requests
  re-check cache staleness after acquiring the lock; only the first
  caller runs git fetch/rev-parse/log, subsequent callers return the
  cached result
- Check log_result.returncode and raise on failure so a broken git log
  doesn't produce a silent false-negative (commits_behind=0)
- Rename loop variable l → commit_line

base.html:
- Replace boolean _dismissed flag with SHA-scoped sessionStorage key
  'update-sha-dismissed'; dismissing for SHA X still allows the banner
  to reappear when origin/main advances to SHA Y
- Successful applyUpdate clears 'update-sha-dismissed' so the next
  update cycle can show the banner again
- Add aria-live="polite" aria-atomic="true" to #update-banner-text so
  screen readers announce content changes

65e3e8319b fix(plugin_manager): prevent permanent ERROR state after update timeout (#316)
* fix(plugin_manager): prevent permanent ERROR state after update timeout

When execute_update() fails (timeout or unhandled exception), the plugin
state was set to ERROR with no recovery path. can_execute() returns False
for ERROR state, so the plugin's update() was never called again, leaving
it showing stale data indefinitely.

Instead, update plugin_last_update so the plugin waits one configured
interval before retrying, and keep the state ENABLED so recovery is
automatic on the next cycle.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(plugin_manager): address PR review — failure timestamp and error context

- Use time.time() at the point of failure instead of reusing current_time
  (captured before execution), so the full retry interval always elapses
  after a timeout rather than one execution-duration shorter

- Add PluginStateManager.set_error_info() to persist structured error context
  without changing plugin state; call it in both failure branches so
  get_error_info() / get_state_info() surface recoverable errors alongside
  ERROR-state errors

- Add warning log on the success=False branch (was previously silent)

- Pass a descriptive Exception (not a generic "Plugin execution failed") to
  health_tracker.record_failure() in the timeout/executor-error path

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(plugin_manager): atomic state+error write via set_state_with_error

The two-step set_state() / set_error_info() sequence left a window where
readers could observe ENABLED state without the accompanying error context.

Add threading.RLock to PluginStateManager and a new set_state_with_error()
method that holds the lock for both the state-transition write and the
_error_info write together. The method inlines the state-transition logic
rather than calling set_state() internally to intentionally skip the
"clear _error_info for non-ERROR states" side effect — the recoverable
error dict is exactly what we want stored.

Replace both paired set_state / set_error_info call sites in
run_scheduled_updates() with the single atomic method.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(plugin_state): lock _error_info accesses and store defensive copies

Three verified issues:

- set_error_info wrote _error_info without holding _lock and stored the
  caller's dict by reference, allowing races and post-write mutation
- set_state_with_error stored error_info by reference (lock was already held)
- get_error_info read _error_info without _lock and returned the live
  reference, letting callers mutate the stored snapshot

Implicit fourth fix: set_state also wrote _error_info without _lock; locking
get_error_info while leaving that writer unguarded would have created a new
race, so set_state is now wrapped in _lock too for consistency.

Changes:
- set_state: wrap entire body in self._lock (covers _states, _state_history,
  and _error_info writes atomically; ERROR-path _error_info value was already
  a fresh dict literal so no copy needed)
- set_error_info: acquire self._lock + store dict(error_info) shallow copy
- set_state_with_error: store dict(error_info) shallow copy (lock already held)
- get_error_info: acquire self._lock + return dict(info) copy or None

All stored values are flat dicts of strings/floats/bools, so shallow copy
is sufficient — deepcopy is not needed.

* fix(plugin_manager): apply recovery logic to update_all_plugins; extract helper

update_all_plugins still set PluginState.ERROR on both failure paths, leaving
it inconsistent with the run_scheduled_updates fix from the same PR.

Extract _record_update_failure(plugin_id, exc=None) to hold all shared failure
logic: capture actual failure time, build structured error_info, log the retry
warning, stamp plugin_last_update, call set_state_with_error(ENABLED), and
forward to health_tracker. Replace all four failure sites (two in
run_scheduled_updates, two in update_all_plugins) with calls to this helper.

4ef3f8cad5 feat(web): add config backup & restore UI (#310)
* feat(web): add config backup & restore UI

Adds a Backup & Restore tab to the v3 web UI that packages user config,
secrets, WiFi, user-uploaded fonts, plugin image uploads, and the installed
plugin list into a single ZIP for safe reinstall recovery. Restore extracts
the bundle, snapshots current state via the existing atomic config manager
(so rollback stays available), reapplies the selected sections, and
optionally reinstalls missing plugins from the store.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(backup): address PR review findings

- backup_manager: read plugin state from "states" key (not "plugins") to
  match the actual plugin_state.json format written by state_manager
- backup_manager: stream ZIP directly to a temp file instead of building
  it in an io.BytesIO buffer to avoid OOM on Raspberry Pi
- backup_manager: tighten plugin-uploads path validation in validate_backup
  and restore_backup to require "/uploads/" in the path, rejecting any
  non-uploads files smuggled under assets/plugins/
- api_v3: enforce 200 MB upload limit by streaming in chunks rather than
  relying on validate_file_upload (which only checks the filename)
- api_v3: replace bool() with _coerce_to_bool() for RestoreOptions fields
  so string "false" is not treated as truthy
- api_v3: capture and log _save_config_atomic return value instead of
  discarding it; log rather than silence font-cache and config-reload errors
- backup_restore.html: track inspectedFile so runRestore always applies to
  the file the user inspected, not a subsequently selected file; clear on
  input change or clearRestore()
- backup_restore.html: throw on non-success restore payload so errors are
  surfaced via the error notification path instead of yellow "warnings"
- test: update fixture to use correct "states" key structure; import
  SCHEMA_VERSION constant instead of hardcoding 1; rename unused err -> _err

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(backup): address second round of PR review findings

- api_v3: guard opts_dict with isinstance check after json.loads so a
  non-object JSON payload (null, array, etc.) returns a 400 instead of a
  500 AttributeError
- backup_manager: wrap tmp ZIP creation and os.replace in try/except so
  the .zip.tmp temp file is always removed on any failure
- backup_manager: replace hardcoded Path("/tmp/_zip_check") sentinel in
  validate_backup with a proper tempfile.TemporaryDirectory() so path
  traversal checks are portable and leave no artifacts
- backup_restore.html: detect partial-success responses (plugins_failed or
  errors non-empty) even when status is 'success' and render yellow/warning
  styling and notify instead of green

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(backup): add post-install steps for restored plugins; conditional restart hint

- api_v3: after a successful plugin reinstall during restore, run the same
  post-install sequence used by the normal /plugins/install flow:
  invalidate schema cache, discover_plugins()/load_plugin(), and
  set_plugin_installed() so restored plugins are immediately available
- backup_restore.html: only show the "restart the display service" hint
  when at least one item was restored or at least one plugin was installed

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(backup): address Codacy findings

- api_v3: replace 'fonts' in ' '.join(result.restored) substring check
  with any(r.startswith("fonts") for r in result.restored) to avoid
  fragile joined-string membership testing
- api_v3: replace deprecated datetime.utcnow() and utcfromtimestamp()
  with datetime.now(timezone.utc) and fromtimestamp(..., timezone.utc);
  add timezone to import
- test: remove unused import io (backup_manager no longer uses BytesIO)
- src/backup_manager.py hardcoded /tmp sentinel was already fixed in a
  prior commit (tempfile.TemporaryDirectory)

338bdc44cb fix(web): list calendar endpoint works without a running plugin instance (#314)
* fix(web): list calendar endpoint works without a running plugin instance

The web service (ledmatrix-web) and display service (ledmatrix) run in
separate processes. The web process discovers plugins but never
instantiates them — only the display process does. Consequently
api_v3.plugin_manager.get_plugin('calendar') always returns None in the
web process, and /api/v3/plugins/calendar/list-calendars responded with
404 "Calendar plugin is not running. Enable it and save config first."
even when the plugin was enabled, saved, and authenticated.

Fall back to reading token.pickle + credentials.json directly from the
calendar plugin directory and calling the Google Calendar API from the
web process. A live plugin instance is still preferred when available
(e.g. local dev where web and display share a process).

Also surface clearer, actionable error messages for missing/expired
tokens so users know to re-run the authentication step.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(web): address review feedback on calendar list endpoint

- Remove unused creds_path local
- Prefer google-auth JSON token (token.json) via Credentials.from_authorized_user_file; keep pickle fallback for backward compat, guarded by a size check and a comment describing the trust boundary (owner-only file inside the plugin dir, not user-supplied input)
- Do NOT persist refreshed credentials from the web request path; the display service owns token.pickle and concurrent writes could corrupt it. Refresh happens in memory only for the duration of the request
- Add explicit timeouts to token refresh (via Request(timeout=...)) and to the Calendar API list call (num_retries=1), and return a retryable user-facing message on socket.timeout / TimeoutError
- Import socket at module scope

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(web): apply real socket timeout to Google Calendar API calls

googleapiclient's execute() does not accept a timeout kwarg — the
timeout comes from the httplib2.Http the service was built with.
Build an AuthorizedHttp wrapping httplib2.Http(timeout=15) so
calendarList().list().execute() cannot hang the Flask worker on
flaky connectivity. Disable discovery doc caching to avoid the
default file-cache warning in this ephemeral request path.

73c00140df fix(web): resolve ReferenceError in single-file upload handler (#313)
The finally block in handleSingleFileUpload referenced an undefined
fileInput variable left over from an earlier refactor, causing an
"Unhandled promise rejection: ReferenceError" after every single-file
upload (e.g. OAuth credentials.json for the calendar plugin) even when
the upload itself succeeded.

Resolve the file input by id inside the finally block so it can be
cleared when present, tolerating the drop-zone-only case.

68a38c39f7 fix(web-ui-info): syntax error and init order crash on fresh install (#312)
Two bugs that prevented the web-ui-info default plugin from loading:

1. Orphaned `except Exception` at line 203 with no matching `try` —
   caused a SyntaxError preventing the module from importing at all.
   Removed the orphan; the outer try/except already covers the block.

2. `_get_local_ip()` called in __init__ before `_ap_mode_cache_time`
   was initialized, causing AttributeError. Moved AP mode cache field
   initialization above the `_get_local_ip()` call.

941291561a fix(web): expose GitHub install handlers, simplify Alpine loader, explicit Flask threading (#305)
A user reported that buttons in the v3 web UI were unresponsive in Safari
after a fresh install. The screenshots showed Alpine.js actually running
fine end-to-end — the real issues are a narrow handler-exposure bug and
some latent brittleness worth cleaning up at the same time.

plugins_manager.js: attachInstallButtonHandler and setupGitHubInstallHandlers
were declared inside the main IIFE, but the typeof guards that tried to
expose them on window ran *outside* the IIFE, so typeof always evaluated
to 'undefined' and the assignments were silently skipped. The GitHub
"Install from URL" button therefore had no click handler and the console
printed [FALLBACK] attachInstallButtonHandler not available on window on
every load. Fixed by assigning window.attachInstallButtonHandler and
window.setupGitHubInstallHandlers *inside* the IIFE just before it closes,
and removing the dead outside-the-IIFE guards.

base.html: the Alpine.js loader was a 50-line dynamic-script + deferLoadingAlpine
+ isAPMode branching block. script.defer = true on a dynamically-inserted
<script> is a no-op (dynamic scripts are always async), the
deferLoadingAlpine wrapper was cargo-culted, and the AP-mode branching
reached out to unpkg unnecessarily on LAN installs even though
alpinejs.min.js already ships in web_interface/static/v3/js/. Replaced
with a single <script defer src="..."> tag pointing at the local file plus
a small window-load rescue that only pulls the CDN copy if window.Alpine
is still undefined.

start.py / app.py: app.run() has defaulted to threaded=True since Flask
1.0 so this is not a behavior change, but the two long-lived
/api/v3/stream/* SSE endpoints would starve every other request under a
single-threaded server. Setting threaded=True explicitly makes the
intent self-documenting and guards against future regressions.

39ccdcf00d fix(plugins): stop reconciliation install loop, slow plugin list, uninstall resurrection (#309)
* fix(plugins): stop reconciliation install loop, slow plugin list, and uninstall resurrection

Three interacting bugs reported by a user (Discord/ericepe) on a fresh install:

1. The state reconciler retried failed auto-repairs on every HTTP request,
   pegging CPU and flooding logs with "Plugin not found in registry: github
   / youtube". Root cause: ``_run_startup_reconciliation`` reset
   ``_reconciliation_started`` to False on any unresolved inconsistency, so
   ``@app.before_request`` re-fired the entire pass on the next request.
   Fix: run reconciliation exactly once per process; cache per-plugin
   unrecoverable failures inside the reconciler so even an explicit
   re-trigger stays cheap; add a registry pre-check to skip the expensive
   GitHub fetch when we already know the plugin is missing; expose
   ``force=True`` on ``/plugins/state/reconcile`` so users can retry after
   fixing the underlying issue.

2. Uninstalling a plugin via the UI succeeded but the plugin reappeared.
   Root cause: a race between ``store_manager.uninstall_plugin`` (removes
   files) and ``cleanup_plugin_config`` (removes config entry) — if
   reconciliation fired in the gap it saw "config entry with no files" and
   reinstalled. Fix: reorder uninstall to clean config FIRST, drop a
   short-lived "recently uninstalled" tombstone on the store manager that
   the reconciler honors, and pass ``store_manager`` to the manual
   ``/plugins/state/reconcile`` endpoint (it was previously omitted, which
   silently disabled auto-repair entirely).

3. ``GET /plugins/installed`` was very slow on a Pi4 (UI hung on
   "connecting to display" for minutes, ~98% CPU). Root causes: per-request
   ``discover_plugins()`` + manifest re-read + four ``git`` subprocesses per
   plugin (``rev-parse``, ``--abbrev-ref``, ``config``, ``log``). Fix:
   mtime-gate ``discover_plugins()`` and drop the per-plugin manifest
   re-read in the endpoint; cache ``_get_local_git_info`` keyed on
   ``.git/HEAD`` mtime so subprocesses only run when the working copy
   actually moved; bump registry cache TTL from 5 to 15 minutes and fall
   back to stale cache on transient network failure.

Tests: 16 reconciliation cases (including 5 new ones covering the
unrecoverable cache, force-reconcile path, transient-failure handling, and
recently-uninstalled tombstone) and 8 new store_manager cache tests
covering tombstone TTL, git-info mtime cache hit/miss, and the registry
stale-cache fallback. All 24 pass; the broader 288-test suite continues to
pass with no new failures.

* perf(plugins): parallelize Plugin Store browse and extend metadata cache TTLs

Follow-up to the previous commit addressing the Plugin Store browse path
specifically. Most users install plugins via the store (ZIP extraction,
no .git directory) so the git-info mtime cache from the previous commit
was a no-op for them; their pain was coming from /plugins/store/list.

Root cause. search_plugins() enriched each returned plugin with three
serial GitHub fetches: _get_github_repo_info (repo API), _get_latest_commit_info
(commits API), _fetch_manifest_from_github (raw.githubusercontent.com).
Fifteen plugins × three requests × serial HTTP = 30–45 sequential round
trips on every cold browse. On a Pi4 over WiFi that translated directly
into the "connecting to display" hang users reported. The commit and
manifest caches had a 5-minute TTL, so even a brief absence re-paid the
full cost.

Changes.

- ``search_plugins``: fan out per-plugin enrichment through a
  ``ThreadPoolExecutor`` (max 10 workers, stays well under unauthenticated
  GitHub rate limits). Apply category/tag/query filters before enrichment
  so we never waste requests on plugins that will be filtered out.
  ``executor.map`` preserves input order, which the UI depends on.
- ``commit_cache_timeout`` and ``manifest_cache_timeout``: 5 min → 30 min.
  Keeps the cache warm across a realistic session while still picking up
  upstream updates in a reasonable window.
- ``_get_github_repo_info`` and ``_get_latest_commit_info``: stale-on-error
  fallback. On a network failure or a 403 we now prefer a previously-
  cached value over the zero-default, matching the pattern already in
  ``fetch_registry``. Flaky Pi WiFi no longer causes star counts to flip
  to 0 and commit info to disappear.

Tests (5 new in test_store_manager_caches.py).

- ``test_results_preserve_registry_order`` — the parallel map must still
  return plugins in input order.
- ``test_filters_applied_before_enrichment`` — category/tag/query filters
  run first so we don't waste HTTP calls.
- ``test_enrichment_runs_concurrently`` — peak-concurrency check plus a
  wall-time bound that would fail if the code regressed to serial.
- ``test_repo_info_stale_on_network_error`` — repo info falls back to
  stale cache on RequestException.
- ``test_commit_info_stale_on_network_error`` — commit info falls back to
  stale cache on RequestException.

All 29 tests (16 reconciliation, 13 store_manager caches) pass.

* perf(plugins): drop redundant per-plugin manifest.json fetch in search_plugins

Benchmarking the previous parallelization commit on a real Pi4 revealed
that the 10x speedup I expected was only ~1.1x. Profiling showed two
plugins (football-scoreboard, ledmatrix-flights) each spent 5 seconds
inside _fetch_manifest_from_github — not on the initial HTTP call, but
on the three retries in _http_get_with_retries with exponential backoff
after transient DNS failures. Even with the thread pool, those 5-second
tail latencies stayed in the wave and dominated wall time.

The per-plugin manifest fetch in search_plugins is redundant anyway.
The registry's plugins.json already carries ``description`` (it is
generated from each plugin's manifest by update_registry.py at release
time), and ``last_updated`` is filled in from the commit info that we
already fetch in the same loop. Dropping the manifest fetch eliminates
one of the three per-plugin HTTPS round trips entirely, which also
eliminates the DNS-retry tail.

The _fetch_manifest_from_github helper itself is preserved — it is
still used by the install path.

Tests unchanged (the search_plugins tests mock all three helpers and
still pass); this drop only affects the hot-path call sequence.

* test: lock down install/update/uninstall invariants

Regression guard for the caching and tombstone changes in this PR:

- ``install_plugin`` must not be gated by the uninstall tombstone. The
  tombstone only exists to keep the state reconciler from resurrecting a
  freshly-uninstalled plugin; explicit user-initiated installs via the
  store UI go straight to ``install_plugin()`` and must never be blocked.
  Test: mark a plugin recently uninstalled, stub out the download, call
  ``install_plugin``, and assert the download step was reached.

- ``get_plugin_info(force_refresh=True)`` must forward force_refresh
  through to both ``_get_latest_commit_info`` and ``_fetch_manifest_from_github``,
  so that install_plugin and update_plugin (both of which call
  get_plugin_info with force_refresh=True) continue to bypass the 30-min
  cache TTLs introduced in c03eb8db. Without this, bumping the commit
  cache TTL could cause users to install or update to a commit older than
  what GitHub actually has.

* fix(plugins): address review findings — transactional uninstall, registry error propagation, payload hardening

Three real bugs surfaced by review, plus one nitpick. Each was verified
against the current code before fixing.

1. fetch_registry silently swallowed network errors, breaking the
   reconciler (CONFIRMED BUG).

   The stale-cache fallback I added in c03eb8db made fetch_registry
   return {"plugins": []} on network failure when no cache existed —
   which is exactly the state on a fresh boot with flaky WiFi. The
   reconciler's _auto_repair_missing_plugin code assumed an exception
   meant "transient, don't mark unrecoverable" and expected to never
   see a silent empty-dict result. With the silent fallback in place
   on a fresh boot, it would see "no candidates in registry" and
   mark every config-referenced plugin permanently unrecoverable.

   Fix: add ``raise_on_failure: bool = False`` to fetch_registry. UI
   callers keep the stale-cache-fallback default. The reconciler's
   _auto_repair_missing_plugin now calls it with raise_on_failure=True
   so it can distinguish a genuine registry miss from a network error.

2. Uninstall was not transactional (CONFIRMED BUG).

   Two distinct failure modes silently left the system in an
   inconsistent state:

   (a) If ``cleanup_plugin_config`` raised, the code logged a warning
       and proceeded to delete files anyway, leaving an orphan install
       with no config entry.
   (b) If ``uninstall_plugin`` returned False or raised AFTER cleanup
       had already succeeded, the config was gone but the files were
       still on disk — another orphan state.

   Fix: introduce ``_do_transactional_uninstall`` shared by both the
   queue and direct paths. Flow:
     - snapshot plugin's entries in main config + secrets
     - cleanup_plugin_config; on failure, ABORT before touching files
     - uninstall_plugin; on failure, RESTORE the snapshot, then raise
   Both queue and direct endpoints now delegate to this helper and
   surface clean errors to the user instead of proceeding past failure.

3. /plugins/state/reconcile crashed on non-object JSON bodies
   (CONFIRMED BUG).

   The previous code did ``payload.get('force', False)`` after
   ``request.get_json(silent=True) or {}``. If a client sent a bare
   string or array as the JSON body, payload would be that string or
   list and .get() would raise AttributeError. Separately,
   ``bool("false")`` is True, so string-encoded booleans were
   mis-handled.

   Fix: guard ``isinstance(payload, dict)`` and route the value
   through the existing ``_coerce_to_bool`` helper.

4. Nitpick: use ``assert_called_once_with`` in
   test_force_reconcile_clears_unrecoverable_cache. The existing test
   worked in practice (we call reset_mock right before) but the stricter
   assertion catches any future regression where force=True might
   double-fire the install.

Tests added (19 new, 48 total passing):

- TestFetchRegistryRaiseOnFailure (4): flag propagates both
  RequestException and JSONDecodeError, wins over stale cache, and
  the default behavior is unchanged for existing callers.
- test_real_store_manager_empty_registry_on_network_failure (1): the
  key regression test — uses the REAL PluginStoreManager (not a Mock)
  with ConnectionError at the HTTP helper layer, and verifies the
  reconciler does NOT poison _unrecoverable_missing_on_disk.
- TestTransactionalUninstall (4): cleanup failure aborts before file
  removal; file removal failure (both False return and raise) restores
  the config snapshot; happy path still succeeds.
- TestReconcileEndpointPayload (8): bare string / array / null JSON
  bodies, missing force key, boolean true/false, and string-encoded
  "true"/"false" all handled correctly.

All 342 tests in the broader sweep still pass (2 pre-existing
TestDottedKeyNormalization failures reproduce on main and are unrelated).

* style: address review nitpicks in store_manager + test

Four small cleanups, each verified against current code:

1. ``_git_info_cache`` type annotation was ``Dict[str, tuple]`` — too
   loose. Tightened to ``Dict[str, Tuple[float, Dict[str, str]]]`` to
   match what ``_get_local_git_info`` actually stores (mtime + the
   sha/short_sha/branch/... dict it returns). Added ``Tuple`` to the
   typing imports.

2. The ``search_plugins`` early-return condition
   ``if len(filtered) == 1 or not fetch_commit_info and len(filtered) < 4``
   parses correctly under Python's precedence (``and`` > ``or``) but is
   visually ambiguous. Added explicit parentheses to make the intent —
   "single plugin, OR small batch that doesn't need commit info" —
   obvious at a glance. Semantics unchanged.

3. Replaced a Unicode multiplication sign (×) with ASCII 'x' in the
   commit_cache_timeout comment.

4. Removed a dead ``concurrent_workers = []`` declaration from
   ``test_enrichment_runs_concurrently``. It was left over from an
   earlier sketch of the concurrency check — the final test uses only
   ``peak_lock`` and ``peak``.

All 48 tests still pass.

* fix(plugins): address second review pass — cache correctness and rollback

Verified each finding against the current code. All four inline issues
were real bugs; nitpicks 5-7 were valid improvements.

1. _get_latest_commit_info overwrote a good cached value with None on
   all-branches-404 (CONFIRMED BUG).

   The final line of the branch loop unconditionally wrote
   ``self.commit_info_cache[cache_key] = (time.time(), None)``, which
   clobbered any previously-good entry on a single transient failure
   (e.g. an odd 5xx, a temporary DNS hiccup during the branches_to_try
   loop). Fix: if there's already a good prior value, bump its
   timestamp into the backoff window and return it instead. Only
   cache None when we never had a good value.

2. _get_local_git_info cache did not invalidate on fast-forward
   (CONFIRMED BUG).

   Caching on ``.git/HEAD`` mtime alone is wrong: a ``git pull`` that
   fast-forwards the current branch updates ``.git/refs/heads/<branch>``
   (or packed-refs) but leaves HEAD's contents and mtime untouched.
   The cache would then serve a stale SHA indefinitely.

   Fix: introduce ``_git_cache_signature`` which reads HEAD contents,
   resolves ``ref: refs/heads/<name>`` to the corresponding loose ref
   file, and builds a signature tuple of (head_contents, head_mtime,
   resolved_ref_mtime, packed_refs_mtime). A fast-forward bumps the
   ref file's mtime, which invalidates the signature and re-runs git.

3. test_install_plugin_is_not_blocked_by_tombstone swallowed all
   exceptions (CONFIRMED BUG in test).

   ``try: self.sm.install_plugin("bar") except Exception: pass`` could
   hide a real regression in install_plugin that happens to raise.
   Fix: the test now writes a COMPLETE valid manifest stub (id, name,
   class_name, display_modes, entry_point) and stubs _install_dependencies,
   so install_plugin runs all the way through and returns True. The
   assertion is now ``assertTrue(result)`` with no exception handling.

4. Uninstall rollback missed unload/reload (CONFIRMED BUG).

   Previous flow: cleanup → unload (outside try/except) → uninstall →
   rollback config on failure. Problem: if ``unload_plugin`` raised,
   the exception propagated without restoring config. And if
   ``uninstall_plugin`` failed after a successful unload, the rollback
   restored config but left the plugin unloaded at runtime —
   inconsistent.

   Fix: record ``was_loaded`` before touching runtime state, wrap
   ``unload_plugin`` in the same try/except that covers
   ``uninstall_plugin``, and on any failure call a ``_rollback`` local
   that (a) restores the config snapshot and (b) calls
   ``load_plugin`` to reload the plugin if it was loaded before we
   touched it.

5. Nitpick: ``_unrecoverable_missing_on_disk: set`` → ``Set[str]``.
   Matches the existing ``Dict``/``List`` style in state_reconciliation.py.

6. Nitpick: stale-cache fallbacks in _get_github_repo_info and
   _get_latest_commit_info now bump the cached entry's timestamp by a
   60s failure backoff. Without this, a cache entry whose TTL just
   expired would cause every subsequent request to re-hit the network
   until it came back, amplifying the failure. Introduced
   ``_record_cache_backoff`` helper and applied it consistently.

7. Nitpick: replaced the flaky wall-time assertion in
   test_enrichment_runs_concurrently with just the deterministic
   ``peak["count"] >= 2`` signal. ``peak["count"]`` can only exceed 1
   if two workers were inside the critical section simultaneously,
   which is definitive proof of parallelism. The wall-time check was
   tight enough (<200ms) to occasionally fail on CI / low-power boxes.

Tests (6 new, 54 total passing):

- test_cache_invalidates_on_fast_forward_of_current_branch: builds a
  loose-ref layout under a temp .git/, verifies a first call populates
  the cache, a second call with unchanged state hits the cache, and a
  simulated fast-forward (overwriting ``.git/refs/heads/main`` with a
  new SHA and mtime) correctly re-runs git.
- test_commit_info_preserves_good_cache_on_all_branches_404: seeds a
  good cached entry, mocks requests.get to always return 404, and
  verifies the cache still contains the good value afterwards.
- test_repo_info_stale_bumps_timestamp_into_backoff: seeds an expired
  cache, triggers a ConnectionError, then verifies a second lookup
  does NOT re-hit the network (proves the timestamp bump happened).
- test_repo_info_stale_on_403_also_backs_off: same for the 403 path.
- test_file_removal_failure_reloads_previously_loaded_plugin:
  plugin starts loaded, uninstall_plugin returns False, asserts
  load_plugin was called during rollback.
- test_unload_failure_restores_config_and_does_not_call_uninstall:
  unload_plugin raises, asserts uninstall_plugin was never called AND
  config was restored AND load_plugin was NOT called (runtime state
  never changed, so no reload needed).

Broader test sweep: 348/348 pass (2 pre-existing
TestDottedKeyNormalization failures reproduce on main, unrelated).

* fix(plugins): address third review pass — cache signatures, backoff, isolation

All four findings verified as real issues against the current code.

1. _git_cache_signature was missing .git/config (CONFIRMED GAP).

   The cached ``result`` dict from _get_local_git_info includes
   ``remote_url``, which is read from ``.git/config``. But the cache
   signature only tracked HEAD + refs — so a config-only change (e.g.
   ``git remote set-url origin https://...``) would leave the stale
   URL cached indefinitely. This matters for the monorepo-migration
   detection in update_plugin.

   Fix: add ``config_contents`` and ``config_mtime`` to the signature
   tuple. Config reads use the same OSError-guarded pattern as the
   HEAD read.

2. fetch_registry stale fallback didn't bump registry_cache_time
   (CONFIRMED BUG).

   The other caches already had the failure-backoff pattern added in
   the previous review pass (via ``_record_cache_backoff``), but the
   registry cache's stale-fallback branches silently returned the
   cached payload without updating ``registry_cache_time``. Next
   request saw the same expired TTL, re-hit the network, failed
   again — amplifying the original transient failure.

   Fix: bump ``self.registry_cache_time`` forward by the existing
   ``self._failure_backoff_seconds`` (reused — no new constant
   needed) in both the RequestException and JSONDecodeError stale
   branches. Kept the ``raise_on_failure=True`` path untouched so the
   reconciler still gets the exception.

3. _make_client() in the uninstall/reconcile test helper leaked
   MagicMocks into the api_v3 singleton (CONFIRMED RISK).

   Every test call replaced api_v3.config_manager, .plugin_manager,
   .plugin_store_manager, etc. with MagicMocks and never restored them.
   If any later test in the same pytest run imported api_v3 expecting
   original state (or None), it would see the leftover mocks.

   Fix: _make_client now snapshots the original attributes (with a
   sentinel to distinguish "didn't exist" from "was None") and returns
   a cleanup callable. Both setUp methods call self.addCleanup(cleanup)
   so state is restored even if the test raises. On cleanup, sentinel
   entries trigger delattr rather than setattr to preserve the
   "attribute was never set" case.

4. Snapshot helpers used broad ``except Exception`` (CONFIRMED).

   _snapshot_plugin_config caught any exception from
   get_raw_file_content, which could hide programmer errors (TypeError,
   AttributeError) behind the "best-effort snapshot" fallback. The
   legitimate failure modes are filesystem errors (covered by OSError;
   FileNotFoundError is a subclass, IOError is an alias in Python 3)
   and ConfigError (what config_manager wraps all load failures in).

   Fix: narrow to ``(OSError, ConfigError)`` in both snapshot blocks.
   ConfigError was already imported at line 20 of api_v3.py.

Tests added (4 new, 58 total passing):

- test_cache_invalidates_on_git_config_change: builds a realistic
  loose-ref layout, writes .git/config with an "old" remote URL,
  exercises _get_local_git_info, then rewrites .git/config with a
  "new" remote URL + new mtime, calls again, and asserts the cache
  invalidated and returned the new URL.
- test_stale_fallback_bumps_timestamp_into_backoff: seeds an expired
  registry cache, triggers ConnectionError, verifies first call
  serves stale, then asserts a second call makes ZERO new HTTP
  requests (proves registry_cache_time was bumped forward).
- test_snapshot_survives_config_read_error: raises ConfigError from
  get_raw_file_content and asserts the uninstall still completes
  successfully — the narrow exception list still catches this case.
- test_snapshot_does_not_swallow_programmer_errors: raises a
  TypeError from get_raw_file_content (not in the narrow list) and
  asserts it propagates up to a 500, AND that uninstall_plugin was
  never called (proves the exception was caught at the right level).

Broader test sweep: 352/352 pass (2 pre-existing
TestDottedKeyNormalization failures reproduce on main, unrelated).

781224591f fix: post-audit follow-up code fixes (cache, fonts, icons, dev script) (#307)
* fix: post-audit follow-up code fixes (cache, fonts, icons, dev script, CI)

The docs refresh effort (#306, ledmatrix-plugins#92) surfaced seven
code bugs that were intentionally left out of the docs PRs because
they required code changes rather than doc fixes. This PR addresses
the six that belong in LEDMatrix (the seventh — a lacrosse-scoreboard
mode rename — lives in the plugins repo).

Bug 1: cache_manager.delete() AttributeError
  src/common/api_helper.py:287 and
  src/plugin_system/resource_monitor.py:343 both call
  cache_manager.delete(key), which doesn't exist — only
  clear_cache(key=None). Added a delete() alias method on
  CacheManager that forwards to clear_cache(key). Reverts the
  "There is no delete() method" wording in DEVELOPER_QUICK_REFERENCE,
  .cursorrules so the docs match the new shim.

Bug 2: dev_plugin_setup.sh PROJECT_ROOT resolution
  scripts/dev/dev_plugin_setup.sh:9 set PROJECT_ROOT to SCRIPT_DIR
  instead of walking up two levels to the repo root, so PLUGINS_DIR
  resolved to scripts/dev/plugins/ and created symlinks under the
  script's own directory. Fixed the path and removed the stray
  scripts/dev/plugins/of-the-day symlink left by earlier runs.

Bug 3: plugin custom icons regressed from v2 to v3
  web_interface/blueprints/api_v3.py built the /plugins/installed
  response without including the manifest's "icon" field, and
  web_interface/templates/v3/base.html hardcoded
  fas fa-puzzle-piece in all three plugin-tab render sites. Pass
  the icon through the API and read it from the templates with a
  puzzle-piece fallback. Reverts the "currently broken" banners in
  docs/PLUGIN_CUSTOM_ICONS.md and docs/PLUGIN_CUSTOM_ICONS_FEATURE.md.

Bug 4: register_plugin_fonts was never wired up
  src/font_manager.py:150 defines register_plugin_fonts(plugin_id,
  font_manifest) but nothing called it, so plugin manifests with a
  "fonts" block were silently no-ops. Wired the call into
  PluginManager.load_plugin() right after plugin_loader.load_plugin
  returns. Reverts the "not currently wired" warning in
  docs/FONT_MANAGER.md's "For Plugin Developers" section.

Bug 5: dead web_interface_v2 import pattern (LEDMatrix half)
  src/base_odds_manager.py had a try/except importing
  web_interface_v2.increment_api_counter, falling back to a no-op
  stub. The module doesn't exist anywhere in the v3 codebase and
  no API metrics dashboard reads it. Deleted the import block and
  the single call site; the plugins-repo half of this cleanup lands
  in ledmatrix-plugins#<next>.

Bug 7: no CI test workflow
  .github/workflows/ only contained security-audit.yml; pytest ran
  locally but was not gated on PRs. Added
  .github/workflows/tests.yml running pytest against Python 3.10,
  3.11, 3.12 in EMULATOR=true mode, skipping tests marked hardware
  or slow. Updated docs/HOW_TO_RUN_TESTS.md to reflect that the
  workflow now exists.

Verification done locally:
  - CacheManager.delete(key) round-trips with set/get
  - base_odds_manager imports without the v2 module present
  - dev_plugin_setup.sh PROJECT_ROOT resolves to repo root
  - api_v3 and plugin_manager compile clean
  - tests.yml YAML parses
  - Script syntax check on dev_plugin_setup.sh

* fix: address CodeRabbit review comments on #307

- src/cache_manager.py: clear_cache(key) treated empty string as
  "wipe all" because of `if key:`. Switched to `key is None`
  branching, made delete(key) and clear_cache(key) reject empty
  strings and None outright with ValueError, and updated both
  docstrings to make the contract explicit. Verified locally
  with a round-trip test that clear_cache() (no arg) still
  wipes everything but clear_cache("") and delete("") raise.

- src/plugin_system/plugin_manager.py: was reaching for the
  font manager via getattr(self.display_manager, 'font_manager',
  None). PluginManager already takes a dedicated font_manager
  parameter (line 54) and stores it as self.font_manager
  (line 69), so the old path was both wrong and could miss the
  font manager entirely when the host injects them separately.
  Switched to self.font_manager directly with the same try/except
  warning behavior.

- web_interface/templates/v3/base.html: in the full plugin-tab
  renderer, the icon was injected with
  `<i class="${escapeHtml(plugin.icon)}">` — but escapeHtml only
  escapes <, >, and &, not double quotes, so a manifest with a
  quote in its icon string could break out of the class
  attribute. Replaced the innerHTML template with createElement
  for the <i> tag, set className from plugin.icon directly
  (no string interpolation), and used a text node for the
  label. Same fix shape would also harden the two stub-renderer
  sites at line 515 / 774, but those already escape `"` to
  &quot; and CodeRabbit only flagged this site, so leaving them
  for now.

- docs/FONT_MANAGER.md: clarified that the Manual Font Overrides
  *workflow* (set_override / remove_override / font_overrides.json)
  is the supported override path today, and only the Fonts tab
  in the web UI is the placeholder. Previous wording conflated
  the two and made it sound like overrides themselves were
  broken.

- docs/HOW_TO_RUN_TESTS.md: replaced the vague "see the PR
  adding it" with a concrete link to #307 and a note that the
  workflow file itself is held back pending the workflow scope.

601fedb9b4 fix(logos): register NCAA lacrosse + women's hockey in logo downloader (#308)
The lacrosse-scoreboard plugin renders broken on hardware: school
logos never appear, and SportsRecent/SportsUpcoming
_draw_scorebug_layout() falls into its "Logo Error" fallback
branch instead of drawing the normal logo-centric scorebug.

Root cause: src/logo_downloader.py LOGO_DIRECTORIES and
API_ENDPOINTS were missing entries for ncaam_lacrosse and
ncaaw_lacrosse, even though the plugin's manager files set those
exact sport_key values (ncaam_lacrosse_managers.py:29,
ncaaw_lacrosse_managers.py:29). The plugin's vendored sports.py
asks the main LogoDownloader to resolve sport_key →
on-disk directory the same way every other sports plugin does
(football, basketball, baseball, hockey), and
get_logo_directory() fell through to the safe fallback
f'assets/sports/{league}_logos' = 'assets/sports/ncaam_lacrosse_logos',
a directory that does not exist. Logo loads then failed for
every team and the scorebug layout collapsed to "Logo Error".

Adding the two lacrosse rows (and the missing ncaaw_hockey row
in API_ENDPOINTS, while we're here) makes lacrosse a first-class
peer to the other NCAA sports — same shared assets/sports/ncaa_logos
directory, same canonical ESPN team-list endpoint pattern. No
plugin-side change is needed because the plugin already imports
the main LogoDownloader.

Existing NCAA football/hockey schools that also play lacrosse
(DUKE, UVA, MD, NAVY, ARMY, YALE, SYR, …) get picked up
immediately on first render. Lacrosse-specific schools (JHU,
Loyola, Princeton, Cornell, Stony Brook, …) lazily download
into the shared directory via download_missing_logo() the first
time they appear in a scoreboard payload — verified locally
with both the team_id fallback path (ESPN sports.core.api) and
the direct logo_url path used by the plugin at runtime.

Verification (all from a clean clone):

  python3 -c "
  from src.logo_downloader import LogoDownloader
  d = LogoDownloader()
  for k in ('ncaam_lacrosse','ncaaw_lacrosse','ncaam_hockey','ncaaw_hockey'):
      print(k, '->', d.get_logo_directory(k))
  "
  # All four print .../assets/sports/ncaa_logos

  python3 -c "
  from pathlib import Path
  from src.logo_downloader import download_missing_logo
  ok = download_missing_logo(
      'ncaam_lacrosse', team_id='120', team_abbreviation='JHU',
      logo_path=Path('assets/sports/ncaa_logos/_jhu_test.png'),
      logo_url='https://a.espncdn.com/i/teamlogos/ncaa/500/120.png',
  )
  print('downloaded:', ok)  # True, ~40KB PNG
  "

6812dfe7a6 docs: refresh and correct stale documentation across repo (#306)
* docs: refresh and correct stale documentation across repo

Walked the README and docs/ tree against current code and fixed several
real bugs and many stale references. Highlights:

User-facing
- README.md: web interface install instructions referenced
  install_web_service.sh at the repo root, but it actually lives at
  scripts/install/install_web_service.sh.
- docs/GETTING_STARTED.md: every web UI port reference said 5050, but
  the real server in web_interface/start.py:123 binds 5000. Same bug
  was duplicated in docs/TROUBLESHOOTING.md (17 occurrences). Fixed
  both.
- docs/GETTING_STARTED.md: rewrote tab-by-tab instructions. The doc
  referenced "Plugin Store", "Plugin Management", "Sports Configuration",
  "Durations", and "Font Management" tabs - none of which exist. Real
  tabs (verified in web_interface/templates/v3/base.html) are: Overview,
  General, WiFi, Schedule, Display, Config Editor, Fonts, Logs, Cache,
  Operation History, Plugin Manager (+ per-plugin tabs).
- docs/GETTING_STARTED.md: removed references to a "Test Display"
  button (doesn't exist) and "Show Now" / "Stop" plugin buttons. Real
  controls are "Run On-Demand" / "Stop On-Demand" inside each plugin's
  tab (partials/plugin_config.html:792).
- docs/TROUBLESHOOTING.md: removed dead reference to
  troubleshoot_weather.sh (doesn't exist anywhere in the repo); weather
  is now a plugin in ledmatrix-plugins.

Developer-facing
- docs/PLUGIN_API_REFERENCE.md: documented draw_image() doesn't exist
  on DisplayManager. Real plugins paste onto display_manager.image
  directly (verified in src/base_classes/{baseball,basketball,football,
  hockey}.py). Replaced with the canonical pattern.
- docs/PLUGIN_API_REFERENCE.md: documented cache_manager.delete() doesn't
  exist. Real method is clear_cache(key=None). Updated the section.
- docs/PLUGIN_API_REFERENCE.md: added 10 missing BasePlugin methods that
  the doc never mentioned: dynamic-duration hooks, live-priority hooks,
  and the full Vegas-mode interface.
- docs/PLUGIN_DEVELOPMENT_GUIDE.md: same draw_image fix.
- docs/DEVELOPMENT.md: corrected the "Plugin Submodules" section. Plugins
  are NOT git submodules - .gitmodules only contains
  rpi-rgb-led-matrix-master. Plugins are installed at runtime into the
  plugins directory configured by plugin_system.plugins_directory
  (default plugin-repos/). Both internal links in this doc were also
  broken (missing relative path adjustment).
- docs/HOW_TO_RUN_TESTS.md: removed pytest-timeout from install line
  (not in requirements.txt) and corrected the test/integration/ path
  (real integration tests are at test/web_interface/integration/).
  Replaced the fictional file structure diagram with the real one.
- docs/EMULATOR_SETUP_GUIDE.md: clone URL was a placeholder; default
  pixel_size was documented as 16 but emulator_config.json ships with 5.

Index
- docs/README.md: rewrote. Old index claimed "16-17 files after
  consolidation" but docs/ actually has 38 .md files. Four were missing
  from the index entirely (CONFIG_DEBUGGING, DEV_PREVIEW,
  PLUGIN_ERROR_HANDLING, STARLARK_APPS_GUIDE). Trimmed the navel-gazing
  consolidation/statistics sections.

Out of scope but worth flagging:
- src/plugin_system/resource_monitor.py:343 and src/common/api_helper.py:287
  call cache_manager.delete(key) but no such method exists on
  CacheManager. Both call sites would AttributeError at runtime if hit.
  Not fixed in this docs PR - either add a delete() shim or convert
  callers to clear_cache().

* docs: fix WEB_INTERFACE_GUIDE and WIFI_NETWORK_SETUP

WEB_INTERFACE_GUIDE.md
- Web UI port: 5050 -> 5000 (4 occurrences)
- Tab list was almost entirely fictional. Documented tabs:
  General Settings, Display Settings, Durations, Sports Configuration,
  Plugin Management, Plugin Store, Font Management. None of these
  exist. Real tabs (verified in web_interface/templates/v3/base.html:
  935-1000): Overview, General, WiFi, Schedule, Display, Config Editor,
  Fonts, Logs, Cache, Operation History, plus Plugin Manager and
  per-plugin tabs in the second nav row. Rewrote the navigation
  section, the General/Display/Plugin sections, and the Common Tasks
  walkthroughs to match.
- Quick Actions list referenced "Test Display" button (doesn't exist).
  Replaced with the real button list verified in
  partials/overview.html:88-152: Start/Stop Display, Restart Display
  Service, Restart Web Service, Update Code, Reboot, Shutdown.
- API endpoints used /api/* paths. The api_v3 blueprint mounts at
  /api/v3 (web_interface/app.py:144), so the real paths are
  /api/v3/config/main, /api/v3/system/status, etc. Fixed.
- Removed bogus "Sports Configuration tab" walkthrough; sports
  favorites live inside each scoreboard plugin's own tab now.
- Plugin directory listed as /plugins/. Real default is plugin-repos/
  (verified in config/config.template.json:130 and
  display_controller.py:132); plugins/ is a fallback.
- Removed "Swipe navigation between tabs" mobile claim (not implemented).

WIFI_NETWORK_SETUP.md
- 21 occurrences of port 5050 -> 5000.
- All /api/wifi/* curl examples used the wrong path. The real wifi
  API routes are at /api/v3/wifi/* (api_v3.py:6367-6609). Fixed.
- ap_password default was documented as "" (empty/open network) but
  config/wifi_config.json ships with "ledmatrix123". Updated the
  Quick Start, Configuration table, AP Mode Settings section, and
  Security Recommendations to match. Also clarified that setting
  ap_password to "" is the way to make it an open network.

* docs: fix ADVANCED_FEATURES and REST_API_REFERENCE

REST_API_REFERENCE.md
- Wrong path: /fonts/delete/<font_family> -> /fonts/<font_family>
  (verified the real DELETE route in
  web_interface/blueprints/api_v3.py).
- Diffed the documented routes against the real api_v3 blueprint
  (92 routes vs the 71 documented). Added missing sections:
  - Error tracking (/errors/summary, /errors/plugin/<id>, /errors/clear)
  - Health (/health)
  - Schedule dim/power (/config/dim-schedule GET/POST)
  - Plugin-specific endpoints (calendar/list-calendars,
    of-the-day/json/upload+delete, plugins/<id>/static/<path>)
  - Starlark Apps (12 endpoints: status, install-pixlet, apps CRUD,
    repository browse/install, upload)
  - Font preview (/fonts/preview)
- Updated table of contents with the new sections.
- Added a footer note that the API blueprint mounts at /api/v3
  (app.py:144) and that SSE stream endpoints are defined directly on
  the Flask app at app.py:607-615.

ADVANCED_FEATURES.md
- Vegas Scroll Mode section was actually accurate (verified all
  config keys match src/vegas_mode/config.py:15-30).

- On-Demand Display section had multiple bugs:
  - 5 occurrences of port 5050 -> 5000
  - All API paths missing /v3 (e.g. /api/display/on-demand/start
    should be /api/v3/display/on-demand/start)
  - "Settings -> Plugin Management -> Show Now Button" UI flow doesn't
    exist. Real flow: open the plugin's tab in the second nav row,
    click Run On-Demand / Stop On-Demand.
  - "Python API Methods" section showed
    controller.show_on_demand() / clear_on_demand() /
    is_on_demand_active() / get_on_demand_info() — none of these
    methods exist on DisplayController. The on-demand machinery is
    all internal (_set_on_demand_*, _activate_on_demand, etc) and
    is driven through the cache_manager. Replaced the section with
    a note pointing to the REST API.
  - All Use Case Examples used the same fictional Python calls.
    Replaced with curl examples against the real API.

- Cache Management section claimed "On-demand display uses Redis cache
  keys". LEDMatrix doesn't use Redis — verified with grep that
  src/cache_manager.py has no redis import. The cache is file-based,
  managed by CacheManager (file at /var/cache/ledmatrix/ or fallback
  paths). Rewrote the manual recovery section:
  - Removed redis-cli commands
  - Replaced cache.delete() Python calls with cache.clear_cache()
    (the real public method per the same bug already flagged in
    PLUGIN_API_REFERENCE.md)
  - Replaced "Settings -> Cache Management" with the real Cache tab
  - Documented the actual cache directory candidates

- Background Data Service section:
  - Used "nfl_scoreboard" as the plugin id in the example.
    The real plugin is "football-scoreboard" (handles both NFL and
    NCAA). Fixed.
  - "Implementation Status: Phase 1 NFL only / Phase 2 planned"
    section was severely outdated. The background service is now
    used by all sports scoreboards (football, hockey, baseball,
    basketball, soccer, lacrosse, F1, UFC), the odds ticker, and
    the leaderboard plugin. Replaced with a current "Plugins using
    the background service" note.

* docs: fix plugin config + store + dependency docs

PLUGIN_STORE_GUIDE.md
- 19 occurrences of port 5050 -> 5000
- All API paths missing /v3 (e.g. /api/plugins/install ->
  /api/v3/plugins/install). Bulk fix.

PLUGIN_REGISTRY_SETUP_GUIDE.md
- Same port + /api/v3 fixes (3 occurrences each)
- "Go to Plugin Store tab" -> "Open the Plugin Manager tab and scroll
  to the Install from GitHub section" (the real flow for registry
  setup is the GitHub install section, not the Plugin Store search)

PLUGIN_CONFIG_QUICK_START.md
- Port 5001 -> 5000 (5001 is the dev_server.py default, not the web UI)
- "Plugin Store tab" install flow -> real Plugin Manager + Plugin Store
  section + per-plugin tab in second nav row
- Removed reference to PLUGIN_CONFIG_TABS_SUMMARY.md (archived doc)

PLUGIN_CONFIGURATION_TABS.md
- "Plugin Management vs Configuration" section confusingly described
  a "Plugins Tab" that doesn't exist as a single thing. Rewrote to
  describe the real two-piece structure: Plugin Manager tab (browse,
  install, toggle) vs per-plugin tabs (configure individual plugins).

PLUGIN_DEPENDENCY_GUIDE.md
- Port 5001 -> 5000

PLUGIN_DEPENDENCY_TROUBLESHOOTING.md
- Wrong port (8080) and wrong UI nav ("Plugin Store or Plugin
  Management"). Fixed to the real flow.

PLUGIN_QUICK_REFERENCE.md
- "Plugin Location: ./plugins/ directory" -> default is plugin-repos/
  (verified in config/config.template.json:130 and
  display_controller.py:132). plugins/ is a fallback.
- File structure diagram showed plugins/ -> plugin-repos/.
- Web UI install flow: "Plugin Store tab" -> "Plugin Manager tab ->
  Plugin Store section". Also fixed Configure ⚙️ button (doesn't
  exist) and "Drag and drop reorder" (not implemented).
- API examples: replaced ad-hoc Python pseudocode with real curl
  examples against /api/v3/plugins/* endpoints. Pointed at
  REST_API_REFERENCE.md for the full list.
- "Migration Path Phase 1-5" was a roadmap written before the plugin
  system shipped. The plugin system is now stable and live. Removed
  the migration phases as they're history, not a roadmap.
- "Quick Migration" section called scripts/migrate_to_plugins.py
  which doesn't exist anywhere in the repo. Removed.
- "Plugin Registry Structure" referenced
  ChuckBuilds/ledmatrix-plugin-registry which doesn't exist. The
  real registry is ChuckBuilds/ledmatrix-plugins. Fixed.
- "Next Steps" / "Questions to Resolve" sections were
  pre-implementation planning notes. Replaced with a "Known
  Limitations" section that documents the actually-real gaps
  (sandboxing, resource limits, ratings, auto-updates).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: fix misc remaining docs (architecture, dev quickref, sub-dir READMEs)

PLUGIN_ARCHITECTURE_SPEC.md
- Added a banner at the top noting this is a historical design doc
  written before the plugin system shipped. The doc is ~1900 lines
  with 13 stale /api/plugins/* paths (real is /api/v3/plugins/*),
  references to web_interface_v2.py (current is app.py), and a
  Migration Strategy / Implementation Roadmap that's now history.
  Banner points readers at the current docs
  (PLUGIN_DEVELOPMENT_GUIDE, PLUGIN_API_REFERENCE,
  REST_API_REFERENCE) without needing to retrofit every section.

PLUGIN_CONFIG_ARCHITECTURE.md
- 10 occurrences of /api/plugins/* missing /v3 prefix. Bulk fixed.

DEVELOPER_QUICK_REFERENCE.md
- cache_manager.delete("key") -> cache_manager.clear_cache("key")
  with comment noting delete() doesn't exist. Same bug already
  documented in PLUGIN_API_REFERENCE.md.

SSH_UNAVAILABLE_AFTER_INSTALL.md
- 4 occurrences of port 5001 -> 5000 in AP-mode and Ethernet/WiFi
  recovery instructions.

PLUGIN_CUSTOM_ICONS_FEATURE.md
- Port 5001 -> 5000.

CONFIG_DEBUGGING.md
- Documented /api/v3/config/plugin/<id> and /api/v3/config/validate
  endpoints don't exist. Replaced with the real endpoints:
  /api/v3/config/main, /api/v3/plugins/schema?plugin_id=,
  /api/v3/plugins/config?plugin_id=. Added a note that validation
  runs server-side automatically on POST.

STARLARK_APPS_GUIDE.md
- "Plugins -> Starlark Apps" UI navigation path doesn't exist (5
  occurrences). Replaced with the real path: Plugin Manager tab,
  then the per-plugin Starlark Apps tab in the second nav row.
- "Navigate to Plugins" install step -> Plugin Manager tab.

web_interface/README.md
- Documented several endpoints that don't exist in the api_v3
  blueprint:
  - GET /api/v3/plugins (list) -> /api/v3/plugins/installed
  - GET /api/v3/plugins/<id> -> doesn't exist
  - POST /api/v3/plugins/<id>/config -> POST /api/v3/plugins/config
  - GET /api/v3/plugins/<id>/enable + /disable -> POST /api/v3/plugins/toggle
  - GET /api/v3/store/plugins -> /api/v3/plugins/store/list
  - POST /api/v3/store/install/<id> -> POST /api/v3/plugins/install
  - POST /api/v3/store/uninstall/<id> -> POST /api/v3/plugins/uninstall
  - POST /api/v3/store/update/<id> -> POST /api/v3/plugins/update
  - POST /api/v3/display/start/stop/restart -> POST /api/v3/system/action
  - GET /api/v3/display/status -> GET /api/v3/system/status
- Also fixed config/secrets.json -> config/config_secrets.json
- Replaced the per-section endpoint duplication with a current real
  endpoint list and a pointer to docs/REST_API_REFERENCE.md.
- Documented that SSE stream endpoints are defined directly on the
  Flask app at app.py:607-615, not in the api_v3 blueprint.

scripts/install/README.md
- Was missing 3 of the 9 install scripts in the directory:
  one-shot-install.sh, configure_wifi_permissions.sh, and
  debug_install.sh. Added them with brief descriptions.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: clarify plugin paths and fix systemd manual install bug

PLUGIN_DEVELOPMENT_GUIDE.md
- Added a "Plugin directory note" callout near the top explaining
  the plugins/ vs plugin-repos/ split:
  - Dev workflow uses plugins/ (where dev_plugin_setup.sh creates
    symlinks)
  - Production / Plugin Store uses plugin-repos/ (the configurable
    default per config.template.json:130)
  - The plugin loader falls back to plugins/ so dev symlinks are
    picked up automatically (schema_manager.py:77)
  - User can set plugins_directory to "plugins" in the General tab
    if they want both to share a directory

CLAUDE.md
- The Project Structure section had plugins/ and plugin-repos/
  exactly reversed:
  - Old: "plugins/ - Installed plugins directory (gitignored)"
         "plugin-repos/ - Development symlinks to monorepo plugin dirs"
  - Real: plugin-repos/ is the canonical Plugin Store install
    location and is not gitignored. plugins/* IS gitignored
    (verified in .gitignore) and is the legacy/dev location used by
    scripts/dev/dev_plugin_setup.sh.
  Reversed the descriptions and added line refs.

systemd/README.md
- "Manual Installation" section told users to copy the unit file
  directly to /etc/systemd/system/. Verified the unit file in
  systemd/ledmatrix.service contains __PROJECT_ROOT_DIR__
  placeholders that the install scripts substitute at install time.
  A user following the manual steps would get a service that fails
  to start with "WorkingDirectory=__PROJECT_ROOT_DIR__" errors.
  Added a clear warning and a sed snippet that substitutes the
  placeholder before installing.

src/common/README.md
- Was missing 2 of the 11 utility modules in the directory
  (verified with ls): permission_utils.py and cli.py. Added brief
  descriptions for both.

Out-of-scope code bug found while auditing (flagged but not fixed):
- scripts/dev/dev_plugin_setup.sh:9 sets PROJECT_ROOT="$SCRIPT_DIR"
  which resolves to scripts/dev/, not the project root. This means
  the script's PLUGINS_DIR resolves to scripts/dev/plugins/ instead
  of the project's plugins/ — confirmed by the existence of
  scripts/dev/plugins/of-the-day/ from prior runs. Real fix is to
  set PROJECT_ROOT="$(cd "$SCRIPT_DIR/../.." && pwd)". Not fixing in
  this docs PR.

* docs: flag aspirational/regressed features in plugin docs

These docs describe features that exist as documented in the doc but
either never wired up or regressed when v3 shipped. Each gets a clear
status banner so plugin authors don't waste time chasing features that
don't actually work.

FONT_MANAGER.md
- The "For Plugin Developers / Plugin Font Registration" section
  documents adding a "fonts" block to manifest.json that gets
  registered via FontManager.register_plugin_fonts(). The method
  exists at src/font_manager.py:150 but is **never called from
  anywhere** in the codebase (verified: zero callers). A plugin
  shipping a manifest "fonts" block has its fonts silently ignored.
  Added a status warning and a note about how to actually ship plugin
  fonts (regular files in the plugin dir, loaded directly).

PLUGIN_IMPLEMENTATION_SUMMARY.md
- Added a top-level status banner.
- Architecture diagram referenced src/plugin_system/registry_manager.py
  (which doesn't exist) and listed plugins/ as the install location.
  Replaced with the real file list (plugin_loader, schema_manager,
  health_monitor, operation_queue, state_manager) and pointed at
  plugin-repos/ as the default install location.
- "Dependency Management: Virtual Environments" — verified there's no
  per-plugin venv. Removed the bullet and added a note that plugin
  Python deps install into the system Python environment, with no
  conflict resolution.
- "Permission System: File Access Control / Network Access /
  Resource Limits / CPU and memory constraints" — none of these
  exist. There's a resource_monitor.py and health_monitor.py for
  metrics/warnings, but no hard caps or sandboxing. Replaced the
  section with what's actually implemented and a clear note that
  plugins run in the same process with full file/network access.

PLUGIN_CUSTOM_ICONS.md and PLUGIN_CUSTOM_ICONS_FEATURE.md
- The custom-icon feature was implemented in the v2 web interface
  via a getPluginIcon() helper in templates/index_v2.html that read
  the manifest "icon" field. When the v3 web interface was built,
  that helper wasn't ported. Verified in
  web_interface/templates/v3/base.html:515 and :774, plugin tab
  icons are hardcoded to `fas fa-puzzle-piece`. The "icon" field in
  plugin manifests is currently silently ignored (verified with grep
  across web_interface/ and src/plugin_system/ — zero non-action-
  related reads of plugin.icon or manifest.icon).
- Added a status banner to both docs noting the regression so plugin
  authors don't think their custom icons are broken in their own
  plugin code.

* docs: fix .cursor/ helper docs

The .cursor/ directory holds the dev-side helper docs that Cursor and
contributors using AI tooling rely on to bootstrap plugin development.
Several of them had the same bug patterns as the user-facing docs.

.cursor/plugin_templates/QUICK_START.md
- "Adding Image Rendering" section showed
  display_manager.draw_image(image, x=0, y=0). That method doesn't
  exist on DisplayManager (same bug as PLUGIN_API_REFERENCE.md and
  PLUGIN_DEVELOPMENT_GUIDE.md). Replaced with the canonical
  display_manager.image.paste((x,y)) pattern, including the
  transparency-mask form.

.cursor/plugins_guide.md
- 10 occurrences of ./dev_plugin_setup.sh — the script lives at
  scripts/dev/dev_plugin_setup.sh, so anyone copy-pasting these
  examples gets "command not found". Bulk fixed via sed.
- "Test with emulator: python run.py --emulator" — there's no
  --emulator flag. Replaced with the real options:
  EMULATOR=true python3 run.py for the full display, or
  scripts/dev_server.py for the dev preview.
- Secrets management section showed a fictional
  "config_secrets": { "api_key": "my-plugin.api_key" } reference
  field. Verified in src/config_manager.py:162-172 that secrets are
  loaded by deep-merging config_secrets.json into the main config.
  There is no separate reference field — just put the secret under
  the same plugin namespace and read it from the merged config.
  Rewrote the section with the real pattern.
- "ssh pi@raspberrypi" -> "ssh ledpi@your-pi-ip" (consistent with
  the rest of LEDMatrix docs which use ledpi as the default user)

.cursor/README.md
- Same ./dev_plugin_setup.sh -> ./scripts/dev/dev_plugin_setup.sh
  fix (×6 occurrences via replace_all).
- Same "python run.py --emulator" -> "EMULATOR=true python3 run.py"
  fix. Also added a pointer to scripts/dev_server.py for previewing
  plugins without running the full display.
- "Example Plugins: plugins/hockey-scoreboard/" — the canonical
  source is the ledmatrix-plugins repo. Installed copies land in
  plugin-repos/ or plugins/. Updated the line to point at the
  ledmatrix-plugins repo and explain both local locations.

* docs: fix .cursorrules — the file Cursor auto-loads to learn the API

This is the file that Cursor reads to learn how plugin development
works. Stale entries here directly mislead AI-assisted plugin authors
on every new plugin. Several of the same bug patterns I've been
fixing in the user-facing docs were here too.

Display Manager section (highest impact)
- "draw_image(image, x, y): Draw PIL Image" — that method doesn't
  exist on DisplayManager. Same bug already fixed in
  PLUGIN_API_REFERENCE.md, PLUGIN_DEVELOPMENT_GUIDE.md,
  ledmatrix-stocks/README.md, and .cursor/plugin_templates/QUICK_START.md.
  Removed the bullet and replaced it with a paragraph explaining the
  real pattern: paste onto display_manager.image directly, then
  update_display(). Includes the transparency-mask form.
- Added the small_font/centered args to draw_text() since they're
  the ones that matter most for new plugin authors
- Added draw_weather_icon since it's commonly used

Cache Manager section
- "delete(key): Remove cached value" — there's no delete() method
  on CacheManager. The real method is clear_cache(key=None) (also
  removes everything when called without args). Same bug as before.
- Added get_cached_data_with_strategy and get_background_cached_data
  since contributors will hit these when working on sports plugins

Plugin System Overview
- "loaded from the plugins/ directory" — clarified that the default
  is plugin-repos/ (per config.template.json:130) with plugins/ as
  the dev fallback used by scripts/dev/dev_plugin_setup.sh

Plugin Development Workflow
- ./dev_plugin_setup.sh -> ./scripts/dev/dev_plugin_setup.sh (×2)
- Manual setup step "Create directory in plugins/<plugin-id>/" ->
  plugin-repos/<plugin-id>/ as the canonical location
- "Use emulator: python run.py --emulator or ./run_emulator.sh"
  — the --emulator flag doesn't exist; ./run_emulator.sh isn't at
  root (it lives at scripts/dev/run_emulator.sh). Replaced with the
  real options: scripts/dev_server.py for dev preview, or
  EMULATOR=true python3 run.py for the full emulator path.

Configuration Management
- "Reference secrets via config_secrets key in main config" — this
  is the same fictional reference syntax I just fixed in
  .cursor/plugins_guide.md. Verified in src/config_manager.py:162-172
  that secrets are deep-merged into the main config; there's no
  separate reference field. Replaced with a clear explanation of
  the deep-merge approach.

Code Organization
- "plugins/<plugin-id>/" -> the canonical location is
  plugin-repos/<plugin-id>/ (or its dev-time symlink in plugins/)
- "see plugins/hockey-scoreboard/ as reference" — the canonical
  source for example plugins is the ledmatrix-plugins repo. Updated
  the pointer.

* Add LICENSE (GPL-3.0) and CONTRIBUTING.md

LICENSE
- The repository previously had no LICENSE file. The README and every
  downstream plugin README already reference GPL-3.0 ("same as
  LEDMatrix project"), but the canonical license text was missing —
  contributors had no formal record of what they were contributing
  under, and GitHub couldn't auto-detect the license for the repo
  banner.
- Added the canonical GPL-3.0 text from
  https://www.gnu.org/licenses/gpl-3.0.txt (verbatim, 674 lines).
- Compatibility verified: rpi-rgb-led-matrix is GPL-2.0-or-later
  (per its COPYING file and README; the "or any later version" clause
  in lib/*.h headers makes GPL-3.0 distribution legal).

CONTRIBUTING.md
- The repository had no CONTRIBUTING file. New contributors had to
  reconstruct the dev setup from DEVELOPMENT.md, PLUGIN_DEVELOPMENT_GUIDE.md,
  SUBMISSION.md, and the root README.
- Added a single page covering: dev environment setup (preview
  server, emulator, hardware), running tests, PR submission flow,
  commit message convention, plugin contribution pointer, and the
  license terms contributors are agreeing to.

> Note for the maintainer: I (the AI assistant doing this audit) am
> selecting GPL-3.0 because every reference in the existing
> documentation already says GPL-3.0 — this commit just makes that
> declaration legally binding by adding the actual file. Please
> confirm during PR review that GPL-3.0 is what you want; if you
> prefer a different license, revert this commit before merging.

* Add CODE_OF_CONDUCT, SECURITY, PR template; link them from README

Tier 1 organizational files that any open-source project at
LEDMatrix's maturity is expected to have. None of these existed
before. They're additive — no existing content was rewritten.

CODE_OF_CONDUCT.md
- Contributor Covenant 2.1 (the de facto standard for open-source
  projects). Mentions both the Discord and the GitHub Security
  Advisories channel for reporting violations.

SECURITY.md
- Private vulnerability disclosure flow with two channels: GitHub
  Security Advisories (preferred) and Discord DM.
- Documents the project's known security model as intentional
  rather than vulnerabilities: no web UI auth, plugins run
  unsandboxed, display service runs as root for GPIO access,
  config_secrets.json is plaintext. These match the limitations
  already called out in PLUGIN_QUICK_REFERENCE.md and the audit
  flagging from earlier in this PR.
- Out-of-scope section points users at upstream
  (rpi-rgb-led-matrix, third-party plugins) so reports land in the
  right place.

.github/PULL_REQUEST_TEMPLATE.md
- 10-line checklist that prompts for the things that would have
  caught the bugs in this very PR: did you load the changed plugin
  once, did you update docs alongside code, are there any plugin
  compatibility implications.
- Linked from CONTRIBUTING.md for the full flow.

README.md
- Added a License section near the bottom (the README previously
  said nothing about the license despite the project being GPL-3.0).
- Added a Contributing section pointing at CONTRIBUTING.md and
  SECURITY.md.

* Customize bug report template for LEDMatrix hardware

The bug_report.md template was the GitHub default and asked
"Desktop (OS/Browser/Version)" and "Smartphone (Device/OS)" — neither
of which is relevant for a project that runs on a Raspberry Pi with
hardware LED panels. A user filing a bug under the old template was
giving us none of the information we'd actually need to triage it.

Replaced with a LEDMatrix-aware template that prompts for:
- Pi model, OS/kernel, panel type, HAT/Bonnet, PWM jumper status,
  display chain dimensions
- LEDMatrix git commit / release tag
- Plugin id and version (if the bug is plugin-related)
- Relevant config snippet (with redaction reminder for API keys)
- journalctl log excerpt with the exact command to capture it
- Optional photo of the actual display for visual issues

Kept feature_request.md as-is — generic content there is fine.

* docs: fix bare /api/plugins paths in PLUGIN_CONFIGURATION_TABS

Found 5 more bare /api/plugins/* paths in PLUGIN_CONFIGURATION_TABS.md
that I missed in the round 2 sweep — they're inside data flow diagrams
and prose ("loaded via /api/plugins/installed", etc.) so the earlier
grep over Markdown code blocks didn't catch them. Fixed all 5 to use
/api/v3/plugins/* (the api_v3 blueprint mount path verified at
web_interface/app.py:144).

Also added a status banner noting that the "Implementation Details"
section references the pre-v3 file layout (web_interface_v2.py,
templates/index_v2.html) which no longer exists. The current
implementation is in web_interface/app.py, blueprints/api_v3.py, and
templates/v3/. Same kind of historical drift I flagged in
PLUGIN_ARCHITECTURE_SPEC.md and the PLUGIN_CUSTOM_ICONS_FEATURE doc.
The user-facing parts of the doc (Overview, Features, Form Generation
Process) are still accurate.

* docs(widgets): list the 20 undocumented built-in widgets

The widget registry README documented 3 widgets (file-upload,
checkbox-group, custom-feeds) but the directory contains 23 registered
widgets total. A plugin author reading this doc would think those 3
were the only built-in options and either reach for a custom widget
unnecessarily or settle for a generic text input.

Verified the actual list with:
  grep -h "register('" web_interface/static/v3/js/widgets/*.js \
    | sed -E "s|.*register\\('([^']+)'.*|\\1|" | sort -u

Added an "Other Built-in Widgets" section after the 3 detailed
sections, listing the remaining 20 with one-line descriptions
organized by category:
- Inputs (6): text-input, textarea, number-input, email-input,
  url-input, password-input
- Selectors (7): select-dropdown, radio-group, toggle-switch,
  slider, color-picker, font-selector, timezone-selector
- Date/time/scheduling (4): date-picker, day-selector, time-range,
  schedule-picker
- Composite/data-source (2): array-table, google-calendar-picker
- Internal (2): notification, base-widget

Pointed at the .js source files as the canonical source for each
widget's exact schema and options — keeps this list low-maintenance
since I'm not duplicating each widget's full options table.

* docs: fix README_NBA_LOGOS and PLUGIN_CONFIGURATION_GUIDE

scripts/README_NBA_LOGOS.md
- "python download_nba_logos.py" — wrong on two counts. The script
  is at scripts/download_nba_logos.py (not the project root), and
  "python" is Python 2 on most systems. Replaced all 4 occurrences
  with "python3 scripts/download_nba_logos.py".
- The doc framed itself as the way to set up "the NBA leaderboard".
  The basketball/leaderboard functionality is now in the
  basketball-scoreboard and ledmatrix-leaderboard plugins (in the
  ledmatrix-plugins repo), which auto-download logos on first run.
  Reframed the script as a pre-population utility for offline / dev
  use cases.
- Bumped the documented Python minimum from 3.7 to 3.9 to match
  the rest of the project.

docs/PLUGIN_CONFIGURATION_GUIDE.md
- The "Plugin Manifest" example was missing 3 fields the plugin
  loader actually requires: id, entry_point, and class_name. A
  contributor copying this manifest verbatim would get
  PluginError("No class_name in manifest") at load time — the same
  loader bug already found in stock-news. Added all three.
- The same example showed config_schema as an inline object. The
  loader expects config_schema to be a file path string (e.g.
  "config_schema.json") with the actual schema in a separate JSON
  file — verified earlier in this audit. Fixed.
- Added a paragraph explaining the loader's required fields and
  the case-sensitivity rule on class_name (the bug that broke
  hello-world's manifest before this PR fixed it).
- "Plugin Manager Class" example had the wrong constructor
  signature: (config, display_manager, cache_manager, font_manager).
  The real BasePlugin.__init__ at base_plugin.py:53-60 takes
  (plugin_id, config, display_manager, cache_manager, plugin_manager).
  A copy-pasted example would TypeError on instantiation. Fixed,
  including a comment noting which attributes BasePlugin sets up.
- Renamed the example class from MyPluginManager to MyPlugin to
  match the project convention (XxxPlugin / XxxScoreboardPlugin
  in actual plugins).

* docs(requirements): document optional dependencies (scipy, psutil, Flask-Limiter)

A doc-vs-code crosscheck of every Python import in src/ and
web_interface/ against requirements.txt found 3 packages that the
code uses but requirements.txt doesn't list. Verified with grep that
all 3 are wrapped in try/except blocks with documented fallback
paths, so they're optional features rather than missing required
deps:

- scipy           src/common/scroll_helper.py:26
                  → from scipy.ndimage import shift; HAS_SCIPY flag.
                  Used for sub-pixel interpolation in scrolling.
                  Falls back to a simpler shift algorithm without it.

- psutil          src/plugin_system/resource_monitor.py:15
                  → import psutil; PSUTIL_AVAILABLE flag. Used for
                  per-plugin CPU/memory monitoring. Silently no-ops
                  without it.

- flask-limiter   web_interface/app.py:42-43
                  → from flask_limiter import Limiter; wrapped at the
                  caller. Used for accidental-abuse rate limiting on
                  the web interface (not security). Web interface
                  starts without rate limiting when missing.

These were latent in two ways:
1. A user reading requirements.txt thinks they have the full feature
   set after `pip install -r requirements.txt`, but they don't get
   smoother scrolling, plugin resource monitoring, or rate limiting.
2. A contributor who deletes one of the packages from their dev env
   wouldn't know which feature they just lost — the fallbacks are
   silent.

Added an "Optional dependencies" section at the bottom of
requirements.txt with the version constraint, the file:line where
each is used, the feature it enables, and the install command. The
comment-only format means `pip install -r requirements.txt` still
gives the minimal-feature install (preserving current behavior),
while users who want the full feature set can copy the explicit
pip install commands.

Other findings from the same scan that came back as false positives
or known issues:
- web_interface_v2: dead pattern flagged in earlier iteration
  (still no real implementation; affects 11+ plugins via the same
  try/except dead-fallback pattern)
- urllib3: comes with `requests` transitively
- All 'src.', 'web_interface.', 'rgbmatrix', 'RGBMatrixEmulator'
  imports: internal modules
- base_plugin / plugin_manager / store_manager / mocks /
  visual_display_manager: relative imports to local modules
- freetype: false positive (freetype-py is in requirements.txt
  under the package name)

* docs: fix broken file references found by path-existence crosscheck

Ran a doc-vs-filesystem crosscheck: extracted every backtick-quoted
path with a file extension or known directory prefix from docs/*.md
and verified each exists. After filtering false positives
(placeholder paths, config keys mistaken for paths, paths inside
docs that already have historical-status banners), found 4 real
broken references — 3 fixed in docs, 1 fixed by creating the missing
file:

docs/HOW_TO_RUN_TESTS.md:339
- Claimed ".github/workflows/tests.yml" exists and runs pytest on
  multiple Python versions in CI. There is no such workflow.
  The only GitHub Actions file is security-audit.yml (bandit + semgrep).
- Pytest runs locally but is NOT gated on PRs.
- Replaced the fictional CI section with the actual state and a
  note explaining how someone could contribute a real test workflow.

docs/MIGRATION_GUIDE.md:92
- Referenced scripts/fix_perms/README.md "(if exists)" — the
  hedge betrays that the writer wasn't sure. The README didn't
  exist. The 6 scripts in scripts/fix_perms/ were never documented.
- Created the missing scripts/fix_perms/README.md from scratch
  with one-line descriptions of all 6 scripts (fix_assets,
  fix_cache, fix_plugin, fix_web, fix_nhl_cache, safe_plugin_rm)
  + when-to-use-each guidance + usage examples.
- Updated MIGRATION_GUIDE link to drop the "(if exists)" hedge
  since the file now exists.

docs/FONT_MANAGER.md:376
- "See test/font_manager_example.py for a complete working example"
  — that file does not exist. Verified by listing test/ directory.
- Replaced with a pointer to src/font_manager.py itself and the
  existing scoreboard base classes in src/base_classes/ that
  actually use the font manager API in production.

Path-existence check methodology:
- Walked docs/ recursively, regex-extracted backtick-quoted paths
  matching either /\.(py|sh|json|yml|yaml|md|txt|service|html|js|css|ttf|bdf|png)/
  or paths starting with known directory prefixes (scripts/, src/,
  config/, web_interface/, systemd/, assets/, docs/, test/, etc.)
- Filtered out URLs, absolute paths (placeholders), and paths
  without slashes (likely not relative refs).
- Checked existence relative to project root.
- Out of 80 unique relative paths in docs/, 32 didn't exist on
  disk. Most were false positives (configkeys mistaken for paths,
  example placeholders like 'assets/myfont.ttf', historical
  references inside docs that already have status banners). The 4
  above were genuine broken refs.

This pattern is reusable for future iterations and worth wiring
into CI (link checker like lychee, scoped to fenced code paths
rather than just markdown links, would catch the same class).

* docs: address CodeRabbit review comments on #306

Reviewed all 12 CodeRabbit comments on PR #306, verified each against
the current code, and fixed the 11 valid ones. The 12th finding is a
real code bug (cache_manager.delete() calls in api_helper.py and
resource_monitor.py) that's already in the planned follow-up code-fix
PR, so it stays out of this docs PR.

Fixed:

.cursor/plugins_guide.md, .cursor/README.md, .cursorrules
- I claimed "there is no --emulator flag" in 3 places. Verified in
  run.py:19-20 that the -e/--emulator flag is defined and functional
  (it sets os.environ["EMULATOR"]="true" before the display imports).
  Other docs I didn't touch (.cursor/plugin_templates/QUICK_START.md,
  docs/PLUGIN_DEVELOPMENT_GUIDE.md) already use the flag correctly.
  Replaced all 3 wrong statements with accurate guidance that
  both forms work and explains the CLI flag's relationship to the
  env var.

.cursorrules, docs/GETTING_STARTED.md, docs/WEB_INTERFACE_GUIDE.md,
docs/PLUGIN_DEVELOPMENT_GUIDE.md
- Four places claimed "the plugin loader also falls back to plugins/".
  Verified that PluginManager.discover_plugins()
  (src/plugin_system/plugin_manager.py:154) only scans the
  configured directory — no fallback. The fallback to plugins/
  exists only in two narrower places: store_manager.py:1700-1718
  (store install/update/uninstall operations) and
  schema_manager.py:70-80 (schema lookup for the web UI form
  generator). Rewrote all four mentions with the precise scope.
  Added a recommendation to set plugin_system.plugins_directory
  to "plugins" for the smoothest dev workflow with
  dev_plugin_setup.sh symlinks.

docs/FONT_MANAGER.md
- The "Status" warning told plugin authors to use
  display_manager.font_manager.resolve_font(...) as a workaround for
  loading plugin fonts. Verified in src/font_manager.py that
  resolve_font() takes a family name, not a file path — so the
  workaround as written doesn't actually work. Rewrote to tell
  authors to load the font directly with PIL or freetype-py in their
  plugin.
- The same section said "the user-facing font override system in the
  Fonts tab still works for any element that's been registered via
  register_manager_font()". Verified in
  web_interface/blueprints/api_v3.py:5404-5428 that
  /api/v3/fonts/overrides is a placeholder implementation that
  returns empty arrays and contains "would integrate with the actual
  font system" comments — the Fonts tab does not have functional
  integration with register_manager_font() or the override system.
  Removed the false claim and added an explicit note that the tab
  is a placeholder.

docs/ADVANCED_FEATURES.md:523
- The on-demand section said REST/UI calls write a request "into the
  cache manager (display_on_demand_config key)". Wrong — verified
  via grep that api_v3.py:1622 and :1687 write to
  display_on_demand_request, and display_on_demand_config is only
  written by the controller during activation
  (display_controller.py:1195, cleared at :1221). Corrected the key
  name and added controller file:line references so future readers
  can verify.

docs/ADVANCED_FEATURES.md:803
- "Plugins using the background service" paragraph listed all
  scoreboard plugins but an orphaned " MLB (baseball)" bullet
  remained below from the old version of the section. Removed the
  orphan and added "baseball/MLB" to the inline list for clarity.

web_interface/README.md
- The POST /api/v3/system/action action list was incomplete. Verified
  in web_interface/app.py:1383,1386 that enable_autostart and
  disable_autostart are valid actions. Added both.
- The Plugin Store section was missing
  GET /api/v3/plugins/store/github-status (verified at
  api_v3.py:3296). Added it.
- The SSE line-range reference was app.py:607-615 but line 619
  contains the "Exempt SSE streams from CSRF and add rate limiting"
  block that's semantically part of the same feature. Extended the
  range to 607-619.

docs/GETTING_STARTED.md
- Rows/Columns step said "Columns: 64 or 96 (match your hardware)".
  The web UI's validation accepts any integer in 16-128. Clarified
  that 64 and 96 are the common bundled-hardware values but the
  valid range is wider.

Not addressed (out of scope for docs PR):

- .cursorrules:184 CodeRabbit comment flagged the non-existent
  cache_manager.delete() calls in src/common/api_helper.py:287 and
  src/plugin_system/resource_monitor.py:343. These are real CODE
  bugs, not doc bugs, and they're the first item in the planned
  post-docs-refresh code-cleanup PR (see
  /home/chuck/.claude/plans/warm-imagining-river.md). The docs in
  this PR correctly state that delete() doesn't exist on
  CacheManager — the fix belongs in the follow-up code PR that
  either adds a delete() shim or updates the two callers.

efe6b1fe23 fix: reduce CPU usage, fix Vegas refresh, throttle high-FPS ticks (#304)
* fix: reduce CPU usage, fix Vegas mid-cycle refresh, and throttle high-FPS plugin ticks

Web UI Info plugin was causing 90%+ CPU on RPi4 due to frequent subprocess
calls and re-rendering. Fixed by: trying socket-based IP detection first
(zero subprocess overhead), caching AP mode checks with 60s TTL, reducing
IP refresh from 30s to 5m, caching rendered display images, and loading
fonts once at init.

Vegas mode was not updating the display mid-cycle because hot_swap_content()
reset the scroll position to 0 on every recomposition. Now saves and
restores scroll position for mid-cycle updates.

High-FPS display loop was calling _tick_plugin_updates() 125x/sec with no
benefit. Added throttled wrapper that limits to 1 call/sec.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: address PR review — respect plugin update_interval, narrow exception handlers

Make _tick_plugin_updates_throttled default to no-throttle (min_interval=0)
so plugin-configured update_interval values are never silently capped.
The high-FPS call site passes an explicit 1.0s interval.

Narrow _load_font exception handler from bare Exception to
FileNotFoundError | OSError so unexpected errors surface.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(vegas): scale scroll position proportionally on mid-cycle hot-swap

When content width changes during a mid-cycle recomposition (e.g., a
plugin gains or loses items), blindly restoring the old scroll_position
and total_distance_scrolled could overshoot the new total_scroll_width
and trigger immediate false completion. Scale both values proportionally
to the new width and clamp scroll_position to stay in bounds.

5ea2acd897 fix(web): array-table Add Item button creates rows with input fields (#302) (#303)
The data-item-properties attribute on the Add Item button was serialized
inside double-quoted HTML using {{ item_properties|tojson|e }}. Jinja2's
|tojson returns Markup (marked safe), making |e a no-op — the JSON
double quotes were not escaped to &quot;. The browser truncated the
attribute at the first " in the JSON, so addArrayTableRow() parsed an
empty object and created rows with only a trash icon.

Fix: switch to single-quote attribute delimiters (JSON only uses double
quotes internally) and filter item_properties to only the display
columns, avoiding large nested objects in the attribute value.

Closes #302

68a0fe1182 fix(web): resolve plugin settings tabs not loading (#301)
* fix(web): resolve plugin settings tabs not loading due to enhancement race

Two co-occurring bugs prevented plugin setting tabs from loading:

1. Both stub-to-full app() enhancement paths (tryEnhance and
   requestAnimationFrame) could fire independently, with the second
   overwriting installedPlugins back to [] after init() already fetched
   them. Added a guard flag (_appEnhanced) and runtime state preservation
   to prevent this race.

2. Plugin config x-init only loaded content if window.htmx was available
   at that exact moment, with no retry or fallback. Added retry loop
   (up to 3s) and fetch() fallback for resilience.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(web): use runtime default tab and add Alpine.initTree to fetch fallback

- Replace hard-coded 'overview' comparison with runtime defaultTab
  (isAPMode ? 'wifi' : 'overview') in both enhancement paths, so
  activeTab is preserved correctly in AP mode
- Add Alpine.initTree(el) call in the plugin config fetch() fallback
  so Alpine directives in the injected HTML are initialized, matching
  the pattern used by loadOverviewDirect and loadWifiDirect

7afc2c0670 fix(web): increase chain_length max from 8 to 32 (#300)
* fix(web): increase chain_length max from 8 to 32

The web UI form input capped chain_length at 8 panels, preventing
users with larger displays (e.g. 16-panel setups) from configuring
their hardware through the UI. The backend API had no such limit.

Changed max="8" to max="32" to support large display configurations.
Added panel count example to the help text.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(web): add server-side bounds validation for display hardware fields

The API endpoint at /api/v3/config/main accepted any integer value for
display hardware fields (chain_length, rows, cols, brightness, etc.)
without bounds checking. Only the HTML form had min/max attributes,
which are trivially bypassed by direct API calls.

Added _int_field_limits dict with bounds for all integer hardware fields:
  chain_length: 1-32, parallel: 1-4, brightness: 1-100,
  rows: 8-128, cols: 16-128, scan_mode: 0-1, pwm_bits: 1-11,
  pwm_dither_bits: 0-2, pwm_lsb_nanoseconds: 50-500,
  limit_refresh_rate_hz: 0-1000, gpio_slowdown: 0-5

Out-of-bounds or non-integer values now return 400 with a clear error
message (e.g. "Invalid chain_length value 99. Must be between 1 and 32.")
before any config is persisted. Follows the same inline validation
pattern already used for led_rgb_sequence, panel_type, and multiplexing.

* fix(api): strict int validation and add max_dynamic_duration_seconds bounds

Reject bool/float types in _int_field_limits validation loop to prevent
silent coercion, and add max_dynamic_duration_seconds to the validation
map so it gets proper bounds checking instead of a raw int() call.

ee4149dc49 fix(vegas): refresh scroll buffer on live score updates (#299)
* fix(vegas): refresh scroll buffer when plugins report live data updates

should_recompose() only checked for cycle completion or staging buffer
content, but plugin updates go to _pending_updates — not the staging
buffer. The scroll display kept showing the old pre-rendered image
until the full cycle ended, even though fresh scores were already
fetched and logged.

Add has_pending_updates() check so hot_swap_content() triggers
immediately when plugins have new data.

Fixes #230

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(vegas): scope hot-swap to visible segments; use monotonic clock

1. Replace has_pending_updates() with has_pending_updates_for_visible_segments()
   so hot_swap_content() only fires when a pending update affects a plugin that
   is actually in the active scroll buffer (with images). Avoids unnecessary
   recomposition when non-visible plugins report updates.

2. Switch all display-loop timing (start_time, elapsed, _next_live_priority_check)
   from time.time() to time.monotonic() to prevent clock-stepping issues from
   NTP adjustments on Raspberry Pi.

5ddf8b1aea fix: live priority now interrupts long display durations (#196) (#298)
* fix: check live priority during display loops to interrupt long durations (#196)

_check_live_priority() was only called once per main loop iteration,
before entering the display duration loop. With dynamic duration enabled,
the loop could run for 60-120+ seconds without ever checking if a
favorite team's live game started — so the display stayed on leaderboard,
weather, etc. while the live game played.

Now both the high-FPS and normal FPS display loops check for live
priority every ~30 seconds (throttled to avoid overhead). When live
content is detected, the loop breaks immediately and switches to the
live game mode.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: update rotation index when live priority interrupts display loop

The live priority break set current_display_mode but not
current_mode_index, so the post-loop rotation logic (which checks the
old active_mode) would overwrite the live mode on the next advance.

Now both loops also set current_mode_index to match the live mode,
mirroring the existing pattern at the top of the main loop (line 1385).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: use timestamp throttle for live priority and skip post-loop rotation

Two issues fixed:

1. The modulo-based throttle (elapsed % 30.0 < display_interval) could
   miss the narrow 8ms window due to timing jitter. Replaced with an
   explicit timestamp check (_next_live_priority_check) that fires
   reliably every 30 seconds.

2. After breaking out of the display loop for live priority, the
   post-loop code (remaining-duration sleep and rotation advancement)
   would still run and overwrite the live mode. Now a continue skips
   directly to the next main loop iteration when current_display_mode
   was changed during the loop.

35df06b8e1 fix: resolve font upload "baseUrl is not defined" error (#235) (#297)
The baseUrl variable was declared inside an IIFE that skips re-execution
on HTMX reloads, so it became undefined when the fonts tab was reloaded.
Since baseUrl was just window.location.origin prepended to absolute paths
like /api/v3/fonts/upload, it was unnecessary — fetch() with a leading
slash already resolves against the current origin.

Remove baseUrl entirely and use relative URLs in all 7 fetch calls.

77e9eba294 fix: overhaul WiFi captive portal for reliable setup (#296)
* fix: overhaul WiFi captive portal for reliable device detection and fast setup

The captive portal detection endpoints were returning "success" responses
that told every OS (iOS, Android, Windows, Firefox) that internet was
working — so the portal popup never appeared. This fixes the core issue
and improves the full setup flow:

- Return portal-triggering redirects when AP mode is active; normal
  success responses when not (no false popups on connected devices)
- Add lightweight self-contained setup page (9KB, no frameworks) for
  the captive portal webview instead of the full UI
- Cache AP mode check with 5s TTL (single systemctl call vs full
  WiFiManager instantiation per request)
- Stop disabling AP mode during WiFi scans (which disconnected users);
  serve cached/pre-scanned results instead
- Pre-scan networks before enabling AP mode so captive portal has
  results immediately
- Use dnsmasq.d drop-in config instead of overwriting /etc/dnsmasq.conf
  (preserves Pi-hole and other services)
- Fix manual SSID input bug that incorrectly overwrote dropdown selection

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: address review findings for WiFi captive portal

- Remove orphaned comment left over from old scan_networks() finally block
- Add sudoers rules for dnsmasq drop-in copy/remove to install script
- Combine cached-network message into single showMsg call (was overwriting)
- Return (networks, was_cached) tuple from scan_networks() so API endpoint
  derives cached flag from the scan itself instead of a redundant AP check
- Narrow exception catch in AP mode cache to SubprocessError/OSError and
  log the failure for remote debugging
- Bound checkNewIP retries to 20 attempts (60s) before showing fallback

6eccb74415 fix: handle dotted schema keys in plugin settings save (#295)
* fix: handle dotted schema keys in plugin settings save (issue #254)

The soccer plugin uses dotted keys like "eng.1" for league identifiers.
PR #260 fixed backend helpers but the JS frontend still corrupted these
keys by naively splitting on dots. This fixes both the JS and remaining
Python code paths:

- JS getSchemaProperty(): greedy longest-match for dotted property names
- JS dotToNested(): schema-aware key grouping to preserve "eng.1" as one key
- Python fix_array_structures(): remove broken prefix re-navigation in recursion
- Python ensure_array_defaults(): same prefix navigation fix

Closes #254

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: address review findings for dotted-key handling

- ensure_array_defaults: replace None nodes with {} so recursion
  proceeds into nested objects (was skipping when key existed as None)
- dotToNested: add tail-matching that checks the full remaining dotted
  tail against the current schema level before greedy intermediate
  matching, preventing leaf dotted keys from being split
- syncFormToJson: replace naive key.split('.') reconstruction with
  dotToNested(flatConfig, schema) and schema-aware getSchemaProperty()
  so the JSON tab save path produces the same correct nesting as the
  form submit path
- Add regression tests for dotted-key array normalization and None
  array default replacement

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: address second round of review findings

- Tests: replace conditional `if response.status_code == 200` guards
  with unconditional `assert response.status_code == 200` so failures
  are not silently swallowed
- dotToNested: guard finalKey write with `if (i < parts.length)` to
  prevent empty-string key pollution when tail-matching consumed all
  parts
- Extract normalizeFormDataForConfig() helper from handlePluginConfigSubmit
  and call it from both handlePluginConfigSubmit and syncFormToJson so
  the JSON tab sync uses the same robust FormData processing (including
  _data JSON inputs, bracket-notation checkboxes, array-of-objects,
  file-upload widgets, checkbox DOM detection, and unchecked boolean
  handling via collectBooleanFields)

2c2fca2219 fix(web): use HTMX for Plugin Manager tab loading (#294)
* fix: auto-repair missing plugins and graceful config fallback

Plugins whose directories are missing (failed update, migration, etc.)
now get automatically reinstalled from the store on startup. The config
endpoint no longer returns a hard 500 when a schema is unavailable —
it falls back to conservative key-name-based masking so the settings
page stays functional.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: handle ledmatrix- prefix in plugin updates and reconciliation

The store registry uses unprefixed IDs (e.g., 'weather') while older
installs used prefixed config keys (e.g., 'ledmatrix-weather'). Both
update_plugin() and auto-repair now try the unprefixed ID as a fallback
when the prefixed one isn't found in the registry.

Also filters system config keys (schedule, display, etc.) from
reconciliation to avoid false positives.

- Move backup-folder filter from _get_config_state to _get_disk_state

- Set _reconciliation_done only after success so failures allow retries
- Replace print() with proper logger in reconciliation
- Wrap load_schema in try/except so exceptions fall through to
  conservative masking instead of 500
- Handle list values in _conservative_mask_config for nested secrets
- Remove duplicate import re

* fix: add thread-safe locking to PluginManager and fix reconciliation retry

PluginManager thread safety:
- Add RLock protecting plugin_manifests and plugin_directories
- Build scan results locally in _scan_directory_for_plugins, then update
  shared state under lock
- Protect reads in get_plugin_info, get_all_plugin_info,
  get_plugin_directory, get_plugin_display_modes, find_plugin_for_mode
- Protect manifest mutation in reload_plugin
- Prevents races between background reconciliation thread and request
  handlers reading plugin state

Reconciliation retry:
- Clear _reconciliation_started on exception so next request retries
- Check result.reconciliation_successful before marking done
- Reset _reconciliation_started on non-success results to allow retry

* fix(web): use HTMX for Plugin Manager tab loading instead of custom fetch

The Plugin Manager tab was the only tab using a custom window.loadPluginsTab()
function with plain fetch() instead of HTMX. This caused a race condition where
plugins_manager.js listened for htmx:afterSwap to initialize, but that event
never fired for the custom fetch. Users had to navigate to a plugin config tab
and back to trigger initialization.

Changes:
- Switch plugins tab to hx-get/hx-trigger="revealed" matching all other tabs
- Remove ~560 lines of dead code (script extraction for a partial with no scripts,
  nested retry intervals, inline HTML card rendering fallbacks)
- Add simple loadPluginsDirect() fallback for when HTMX fails to load
- Remove typeof htmx guard on afterSwap listener so it registers unconditionally
- Tighten afterSwap target check to avoid spurious re-init from other tab swaps

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: address CodeRabbit review findings across plugin system

- plugin_manager.py: clear plugin_manifests/plugin_directories before update
  to prevent ghost entries for uninstalled plugins persisting across scans
- state_reconciliation.py: remove 'enabled' key check that skipped legacy
  plugin configs, default to enabled=True matching PluginManager.load_plugin
- app.py: add threading.Lock around reconciliation start guard to prevent
  race condition spawning duplicate threads; add -> None return annotation
- store_manager.py: use resolved registry ID (alt_id) instead of original
  plugin_id when reinstalling during monorepo migration
- base.html: check Response.ok in loadPluginsDirect fallback; trigger
  fallback on tab click when HTMX unavailable; remove active-tab check
  from 5-second timeout so content preloads regardless

Skipped: api_v3.py secret redaction suggestion — the caller at line 2539
already tries schema-based mask_secret_fields() before falling back to
_conservative_mask_config, making the suggested change redundant.

- plugin_manager.py: skip directories containing '.standalone-backup-'
  during discovery scan, matching state_reconciliation.py behavior and
  preventing backup manifests from overwriting live plugin entries
- base.html: fix hx-on::htmx:response-error → hx-on::response-error
  (the :: shorthand already adds the htmx: prefix, so the original
  syntax resolved to htmx:htmx:response-error making the handler dead)

Skipped findings:
- web-ui-info in _SYSTEM_CONFIG_KEYS: it's a real plugin with manifest.json
  and config entry, not a system key
- store_manager config key migration: valid feature request for handling
  ledmatrix- prefix rename, but new functionality outside this PR scope

* fix(web): add fetch timeout to loadPluginsDirect fallback

Add AbortController with 10s timeout so a hanging fetch doesn't leave
data-loaded set and block retries. Timer is cleared in both success
and error paths.

640a4c1706 fix: auto-repair missing plugins on startup (#293)
* fix: auto-repair missing plugins and graceful config fallback

Plugins whose directories are missing (failed update, migration, etc.)
now get automatically reinstalled from the store on startup. The config
endpoint no longer returns a hard 500 when a schema is unavailable —
it falls back to conservative key-name-based masking so the settings
page stays functional.

* fix: handle ledmatrix- prefix in plugin updates and reconciliation

The store registry uses unprefixed IDs (e.g., 'weather') while older
installs used prefixed config keys (e.g., 'ledmatrix-weather'). Both
update_plugin() and auto-repair now try the unprefixed ID as a fallback
when the prefixed one isn't found in the registry.

Also filters system config keys (schedule, display, etc.) from
reconciliation to avoid false positives.

* fix: address code review findings for plugin auto-repair

- Move backup-folder filter from _get_config_state to _get_disk_state
  where the artifact actually lives
- Run startup reconciliation in a background thread so requests aren't
  blocked by plugin reinstallation
- Set _reconciliation_done only after success so failures allow retries
- Replace print() with proper logger in reconciliation
- Wrap load_schema in try/except so exceptions fall through to
  conservative masking instead of 500
- Handle list values in _conservative_mask_config for nested secrets
- Remove duplicate import re

* fix: add thread-safe locking to PluginManager and fix reconciliation retry

PluginManager thread safety:
- Add RLock protecting plugin_manifests and plugin_directories
- Build scan results locally in _scan_directory_for_plugins, then update
  shared state under lock
- Protect reads in get_plugin_info, get_all_plugin_info,
  get_plugin_directory, get_plugin_display_modes, find_plugin_for_mode
- Protect manifest mutation in reload_plugin
- Prevents races between background reconciliation thread and request
  handlers reading plugin state

Reconciliation retry:
- Clear _reconciliation_started on exception so next request retries
- Check result.reconciliation_successful before marking done
- Reset _reconciliation_started on non-success results to allow retry

48ff624a85 fix: catch ConfigError in display preview generator (#288)
* fix: catch ConfigError in display preview generator

PR #282 narrowed bare except blocks but missed ConfigError from
config_manager.load_config(), which wraps FileNotFoundError,
JSONDecodeError, and OSError. Without this, a corrupt or missing
config crashes the display preview SSE endpoint instead of falling
back to 128x64 defaults.

* fix(security): comprehensive error handling cleanup

- Remove all traceback.format_exc() from client responses (33 remaining instances)
- Sanitize str(e) from client-facing messages, replacing with generic error messages
- Replace ~65 bare print() calls with structured logger.exception/error/warning/info/debug
- Remove ~35 redundant inline `import traceback` and `import logging` statements
- Convert logging.error/warning calls to use module-level named logger
- Fix WiFi endpoints that created redundant inline logger instances
- Add logger.exception() at all WebInterfaceError.from_exception() call sites
- Fix from_exception() in errors.py to use safe messages instead of raw str(exception)
- Apply consistent [Tag] prefixes to all logger calls for production triage

Only safe, user-input-derived str(e) kept: json.JSONDecodeError handlers (400 responses).
Subprocess template print(stdout) calls preserved (not error logging).

* fix(security): correct error inference, remove debug log leak, consolidate config handlers

- _infer_error_code: map Config* exceptions to CONFIG_LOAD_FAILED
  (ConfigError is only raised by load_config(), so CONFIG_SAVE_FAILED
  produced wrong safe message and wrong suggested_fixes)
- Remove leftover DEBUG logs in save_main_config that dumped full
  request body and all HTTP headers (Authorization, Cookie, etc.)
- Replace dead FileNotFoundError/JSONDecodeError/IOError handlers in
  get_dim_schedule_config with single ConfigError catch (load_config
  already wraps these into ConfigError)
- Remove redundant local `from src.exceptions import ConfigError`
  imports now covered by top-level import
- Strip str(e) from client-facing error messages in dim schedule handler

* fix(security): fix plugin update logging and config validation leak

- update_plugin: change logger.exception to logger.error in non-except
  branch (logger.exception outside an except block logs useless
  "NoneType: None" traceback)
- update_plugin: remove duplicate logger.exception call in except block
  (was logging the same failure twice)
- save_plugin_config validation: stop logging full plugin_config dict
  (can contain API keys, passwords, tokens) and raw form_data values;
  log only keys and validation errors instead

442638dd2c fix: add reset() alias to ScrollHelper for plugin compatibility (#290)
Multiple plugins (F1, UFC) independently called scroll_helper.reset()
instead of scroll_helper.reset_scroll(), causing AttributeError and
preventing scroll modes from displaying. Adding reset() as an alias
prevents this class of bugs going forward.

8391832c90 fix(vegas): keep plugin data and visuals fresh during Vegas scroll mode (#291)
* fix(vegas): keep plugin data and visuals fresh during Vegas scroll mode

Plugins using ESPN APIs and other data sources were not updating during
Vegas mode because the render loop blocked for 60-600s per iteration,
starving the scheduled update tick. This adds a non-blocking background
thread that runs plugin updates every ~1s during Vegas mode, bridges
update notifications to the stream manager, and clears stale scroll
caches so all three content paths (native, scroll_helper, fallback)
reflect fresh data.

- Add background update tick thread in Vegas coordinator (non-blocking)
- Add _tick_plugin_updates_for_vegas() bridge in display controller
- Fix fallback capture to call update() instead of only update_data()
- Clear scroll_helper.cached_image on update for scroll-based plugins
- Drain background thread on Vegas stop/exit to prevent races

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix(vegas): address review findings in update pipeline

- Extract _drive_background_updates() helper and call it from both the
  render loop and the static-pause wait loop so plugin data stays fresh
  during static pauses (was skipped by the early `continue`)
- Remove synchronous plugin.update() from the fallback capture path;
  the background update tick already handles API refreshes so the
  content-fetch thread should only call lightweight update_data()
- Use scroll_helper.clear_cache() instead of just clearing cached_image
  so cached_array, total_scroll_width and scroll_position are also reset

fe5c1d0d5e feat(web): add Google Calendar picker widget for dynamic multi-calendar selection (#274)
* fix(install): add --prefer-binary to pip installs to avoid /tmp exhaustion

timezonefinder (~54 MB) includes large timezone polygon data files that pip
unpacks into /tmp during installation. On Raspberry Pi, the default tmpfs
/tmp size (often ~half of RAM) can be too small, causing the install to fail
with an out-of-space error.

Adding --prefer-binary tells pip to prefer pre-built binary wheels over
source distributions. Since timezonefinder and most other packages publish
wheels on PyPI (and piwheels.org has ARM wheels), this avoids the large
temporary /tmp extraction and speeds up installs generally.

* fix(timezone): use America/New_York instead of EST for ESPN API date queries

EST is a fixed UTC-5 offset that does not observe daylight saving time,
causing the ESPN API date to be off by one hour during EDT (March–November).
America/New_York correctly handles DST transitions.

The ESPN scoreboard API anchors its schedule calendar to Eastern US time,
so this Eastern timezone is intentionally kept for the API date — it is not
user-configurable. Game time display is converted separately to the user's
configured timezone.

* feat(web): add Google Calendar picker widget for dynamic calendar selection

Adds a new google-calendar-picker widget and API endpoint that lets users
load their available Google Calendars by name and check the ones they want,
instead of manually typing calendar IDs.

- GET /api/v3/plugins/calendar/list-calendars — calls plugin.get_calendars()
  and returns all accessible calendars with id, summary, and primary flag
- google-calendar-picker.js — new widget: "Load My Calendars" button renders
  a checklist; selections update a hidden comma-separated input for form submit
- plugin_config.html — handles x-widget: google-calendar-picker in array branch
- base.html — loads the new widget script

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(web): address PR review findings in google-calendar-picker

- api_v3.py: replace broad except block with specific exception handling,
  log full traceback via module logger, normalize/validate get_calendars()
  output to stable {id,summary,primary} objects, return opaque user-friendly
  error message instead of leaking str(e)
- google-calendar-picker.js: fix button label only updating to "Refresh
  Calendars" on success (restore original label on error); update summary
  paragraph via syncHiddenAndSummary() on every checkbox change so UI stays
  in sync with hidden input; pass summary element through loadCalendars and
  renderCheckboxes instead of re-querying DOM
- plugin_config.html: bound initWidget retry loop with MAX_RETRIES=40 to
  prevent infinite timers; normalize legacy comma-separated string values
  to arrays before passing to widget.render so pre-existing config populates
  correctly
- install_dependencies_apt.py: update install_via_pip docstring to document
  both --break-system-packages and --prefer-binary flags

* fix(web): harden list_calendar_calendars input validation

- Remove unused `as e` binding from ValueError/TypeError/KeyError except clause
- Replace hasattr(__iter__) with isinstance(list|tuple) so non-sequence returns
  are rejected before iteration
- Validate each calendar entry is a collections.abc.Mapping; skip and warn on
  malformed items rather than propagating a TypeError
- Coerce id/summary to str safely if not already strings

* fix(web): skip calendar entries with empty id in list_calendar_calendars

After coercing cal_id to str, check it is non-empty before appending to
the calendars list so entries with no usable id are never forwarded to
the client.

* fix(store): prevent bulk-update from stalling on bundled/in-repo plugins

Three related bugs caused the bulk plugin update to stall at 3/19:

1. Bundled plugins (e.g. starlark-apps, shipped with LEDMatrix rather
   than the plugin registry) had no metadata file, so update_plugin()
   returned False → API returned 500 → frontend queue halted.
   Fix: check for .plugin_metadata.json with install_type=bundled and
   return True immediately (these plugins update with LEDMatrix itself).

2. git config --get remote.origin.url (without --local) walked up the
   directory tree and found the parent LEDMatrix repo's remote URL for
   plugins that live inside plugin-repos/. This caused the store manager
   to attempt a 60-second git clone of the wrong repo for every update.
   Fix: use --local to scope the lookup to the plugin directory only.

3. hello-world manifest.json had a trailing comma causing JSON parse
   errors on every plugin discovery cycle (fixed on devpi directly).

* fix(march-madness): address PR #263 code review findings

- Replace self.is_enabled with BasePlugin.self.enabled in update(),

- Support quarter-based period labels for NCAAW (Q1..Q4 vs H1..H2),
  detected via league key or status_detail content
- Use live refresh interval (60s) for cache max_age during live games
  instead of hardcoded 300s
- Narrow broad except in _load_round_logos to (OSError, ValueError)
  with a fallback except Exception using logger.exception for traces
- Remove unused `situation` local variable from _parse_event()
- Add numpy>=1.24.0 to requirements.txt (imported but was missing)

* fix(web): render file-upload drop zone for string-type config fields

String fields with x-widget: "file-upload" were falling through to a
plain text input because the template only handled the array case.
Adds a dedicated drop zone branch for string fields and corresponding
handleSingleFileSelect/handleSingleFileUpload JS handlers that POST to
the x-upload-config endpoint. Fixes credentials.json upload for the
calendar plugin.

* fix(march-madness): address PR #271 code review findings

Inline fixes:
- manager.py: swap min_duration/max_duration if misconfigured, log warning
- manager.py: call session.close() and null session in cleanup() to prevent
  socket leaks on constrained hardware
- manager.py: remove blocking network I/O from display(); update() is the
  sole fetch path (already uses 60s live-game interval)
- manager.py: guard scroll_helper None before create_scrolling_image() in
  _create_ticker_image() to prevent crash when ScrollHelper is unavailable
- store_manager.py: replace bare "except Exception: pass" with debug log
  including plugin_id and path when reading .plugin_metadata.json
- file-upload.js: add endpoint guard (error if uploadEndpoint is falsy),
  client-side extension validation from data-allowed-extensions, and
  response.ok check before response.json() in handleSingleFileUpload
- plugin_config.html: add data-allowed-extensions attribute to single-file
  input so JS handler can read the allowed extensions list

Nitpick fixes:
- manager.py: use logger.exception() (includes traceback) instead of
  logger.error() for league fetch errors
- manager.py: remove redundant "{e}" from logger.exception() calls for
  round logo and March Madness logo load errors

Not fixed (by design):
- manifest.json repo naming: monorepo pattern is correct per project docs

* fix(march-madness): address second round of PR #271 code review findings

Inline fixes:
- requirements.txt: bump Pillow to >=9.1.0 (required for Image.Resampling.LANCZOS)
- file-upload.js: replace all statusDiv.innerHTML assignments with safe DOM
  creation (textContent + createElement) to prevent XSS from untrusted strings
- plugin_config.html: add role="button", tabindex="0", aria-label, onkeydown
  (Enter/Space) to drop zone for keyboard accessibility; add aria-live="polite"
  to status div for screen-reader announcements
- file-upload.js: tighten handleFileDrop endpoint check to non-empty string
  (dataset.uploadEndpoint.trim() !== '') so an empty attribute falls back to
  the multi-file handler

Nitpick fixes:
- manager.py: remove redundant cached_image/cached_array reassignments after
  create_scrolling_image() which already sets them internally
- manager.py: narrow bare except in _get_team_logo to (FileNotFoundError,
  OSError, ValueError) for expected I/O errors; log unexpected exceptions
- store_manager.py: narrow except to (OSError, ValueError) when reading
  .plugin_metadata.json so unrelated exceptions propagate
