ChuckandClaude Opus 5.5 7b90759252 fix: /errors stack traces, Wi-Fi disconnect and save, plugin fonts, API cache TTL (#636)
* fix(errors): record the exception's own stack trace

record_error() called traceback.format_exc(), which only sees an
exception while its except block is running. plugin_executor records
exceptions caught on a worker thread after that block has ended, so
every trace on /errors read "NoneType: None". The trace is now built
from the exception's __traceback__. The executor's log call had the
same problem with exc_info=True and now passes the exception.

record_error() also merged LEDMatrixError context into the caller's
dict in place; it now works on a copy.

* docs(wifi): point at configure_wifi_permissions.sh instead of a sudoers list

The module docstring told users to grant NOPASSWD sudo on iptables and
ip. configure_wifi_permissions.sh refuses those grants on purpose: a
wildcard rule for either runs an arbitrary program as root. Point at
the script and say why it leaves them out.

* fix(wifi): disconnect finds the saved profile by SSID

disconnect_from_network() asked `nmcli -f NAME,802-11-wireless.ssid
connection show` for the profile to take down, but nmcli rejects that
column for `connection show`, so the lookup always failed and only the
device was disconnected. The per-profile lookup _connect_nmcli() already
used is now _find_profile_for_ssid(), and both callers share it. It
also splits terse output on the last colon and unescapes "\:", so a
profile name containing a colon is found.

* fix(wifi): write wifi_config.json atomically and report a failed save

_save_config() opened the file for writing in place and swallowed any
error, so a wifi_config.json left owned by root made the web toggle for
auto-enabling AP mode report success while nothing was saved, and a
crash mid-write could truncate the file. It now uses atomic_write_json,
which also keeps the file's owner and shared group when root saves it,
and returns False on failure. POST /wifi/ap/auto-enable answers 500 in
that case.

The file is now written with indent=4, like the other config files.

* fix(fonts): resolve plugin:// fonts in the plugin's own directory

FontManager looked for a plugin's bundled fonts under Path("plugins") /
plugin_id: relative to the process cwd, and not the default install
directory (plugin-repos/), so a manifest's plugin:// fonts never loaded.

register_plugin_fonts() takes an optional plugin_dir, and PluginManager
passes the directory it loaded the plugin from. Callers that omit it get
a lookup in the configured plugin_system.plugins_directory, then plugins/,
resolved against the install root.

* fix(api-helper): cache responses for the requested cache_ttl

APIHelper.get(cache_ttl=...) and set_cache(ttl=...) dropped the ttl on
the claim that CacheManager does not support one, but CacheManager.set()
takes a ttl, stores it with the entry, and both cache tiers honour it
over a reader's max_age. Without it every response expired after the
300-second default read age, whatever the plugin asked for. The ttl is
now passed through, and the cache read passes cache_ttl as max_age for
entries written without one. The class docstring describes what the
helper actually does.

* fix(style): one scale range for the schema, element_scale and LogoHelper

The generated Scale field allowed 0.1 to 10, element_style's reader
capped at 10 with no floor, and LogoHelper accepted 0.05 to 8 and reset
anything else to 1.0. A logo scale of 9, which the form accepts, drew at
the shipped size.

MIN_ELEMENT_SCALE / MAX_ELEMENT_SCALE (0.1, 10.0) in src.element_style
are now the schema bounds and the clamp every reader applies through
coerce_scale(): a positive number outside the range is clamped, and
anything that is not a finite positive number means the default. That
also stops element_scale() passing NaN through, since min(nan, 10.0)
is nan.

* fix(logos): placeholder lands at the requested path; empty logos list

download_missing_logo() wrote its fallback placeholder to
<normalize_abbreviation(abbr)>.png in the logo directory rather than to
the logo_path the caller passed, so it could return True while nothing
existed where the plugin looks (e.g. "TA&M.png" vs "TAANDM.png").
create_placeholder_logo() takes an optional filepath, and
download_missing_logo passes the requested one.

download_missing_logo_for_team() only caught KeyError, so a team whose
"logos" list is empty raised IndexError; it now treats KeyError,
IndexError and TypeError as "no logo URL".

The placeholder is drawn with PLACEHOLDER_SIZE / PLACEHOLDER_BG, the
constants is_placeholder_logo() recognises it by, instead of repeated
literals.

* fix(fonts): resolve bundled font paths against the install root

TextHelper's default font_dir, the logo placeholder's font and
FontManager's font_overrides.json were all relative to the process cwd,
so a process started anywhere but the install root (the plugin safety
harness, a manual run, a unit without WorkingDirectory) drew with PIL's
default face and read no overrides. They now go through
font_layout.resolve_asset_path; the overrides file sits in the install
root's config/.

The resolver docstrings described an order the code does not follow:
resolve_asset_path never consults the cwd, and sports_shared's
_resolve_font_path tries the cwd first. Both docstrings now say what
the code does, and _resolve_font_path calls resolve_asset_path instead
of probing FontManager for it.

* fix(sync): the web UI reads the sync status file the display writes

sync_manager writes its status to tempfile.gettempdir(), but
GET /api/v3/sync/status read a hardcoded /tmp/led_matrix_sync_status.json
and defaulted the port to a literal 5765. Wherever TMPDIR is set (or on
any non-/tmp host) the page only ever showed "starting". The endpoint now
uses sync_manager.STATUS_FILE and SYNC_PORT.

* fix(http): the rankings resolver sends the project's User-Agent

DynamicTeamResolver fetched ESPN rankings with a bare requests.get, so
it sent python-requests' default User-Agent, which ESPN rejects; the
AP_TOP_N favourites then resolved to nothing. It now sends
DEFAULT_HTTP_HEADERS. BaseOddsManager carried its own copy of the
User-Agent string and now uses the same shared headers (which also adds
Accept-Language).

* fix(backup): record the core release and read the configured plugin dir

The manifest's ledmatrix_version came from a VERSION file that does not
exist, then from .git/HEAD: a 12-character sha, or "ref: refs/he" when
the branch's ref was packed. It is now src.__version__.

list_installed_plugins() scanned a hardcoded plugin-repos/, so on an
install whose plugin_system.plugins_directory points elsewhere, plugins
missing from plugin_state.json were left out of the backup. It now reads
the configured directory from config/config.json, defaulting to
plugin-repos.

* fix(startup): report a missing display section once

A config without a display section produced three errors for the one
problem ("Missing required configuration key: display", "Display
configuration is missing or empty" and "Display configuration is
missing"), and an empty one produced two. _validate_config now reports
it once, as a missing key or an empty section, and
_validate_display_config leaves it to that.

The module docstring said the validator fails fast; nothing in the
display service calls raise_on_errors(), so it now says the errors are
reported and startup continues.

* refactor(wifi): share the copied blocks and name the AP constants

- _parse_nmcli_wifi_list() is the one parser behind _scan_nmcli and
  _scan_nmcli_cached.
- _verify_connected(), _wait_for_device_idle(), _failsafe_ap() and
  _mark_forced() replace blocks that were pasted two or three times in
  the connect and enable-AP paths. The device-idle wait now checks
  before its first one-second sleep instead of after it.
- _check_command() calls _find_command_path() instead of repeating it.
- AP_IP, PORTAL_PORT, AP_PROFILE_NAME and AP_PROFILE_NAMES name values
  that were spelled out 14, 12, 8 and 2 times; the two deletion loops
  now walk the same tuple. The iwconfig status path compares the AP
  address exactly: startswith() also skipped 192.168.4.10-19.
- Dropped a second WIFI.SIGNAL query that repeated the first, a no-op
  "if ssid: continue", the try/except around _connect_wpa_supplicant's
  constant return, and a second save of a scan scan_networks already
  saves.
- _ensure_wifi_radio_enabled's docstring says it returns True when the
  radio state cannot be read at all.

* refactor(config): drop dead branches and history comments in ConfigManager

- The module docstring pointed plugin authors at update_plugin_config(),
  which does not exist; it now names save_config_atomic() and
  save_raw_file_content().
- load_config's FileNotFoundError handler tested the message for
  "config_secrets.json", but a missing secrets file is handled where it
  is read, so only config.json reaches it; the check is gone.
- save_raw_file_content's `file_type == "main" or "secrets"` guard was
  always true (anything else raised earlier).
- get_raw_file_content('secrets') already returns {} for a missing file,
  so the os.path.exists() in front of two calls to it is gone.
- Comments that narrated earlier behaviour are rewritten as what the
  code does now.

* refactor(background-data): present-tense comments, drop unused API

- Comments that told the history of each fix (what "used to" happen,
  "the old per-delivery release") now state the invariant the code keeps.
- get_statistics() no longer reports a constant 'queue_size': 0, and the
  uncalled clear_completed_requests() is gone (_cleanup_completed_requests
  does that job on every completion). Neither is referenced in core, the
  web UI or the plugin monorepo.

shutdown_background_service() has no production caller either, but it
is the only way to tear down the get_background_service() singleton,
which the tests rely on, so it stays.

* refactor(odds): drop the unread cache_ttl and merge the odds_data branches

BaseOddsManager loaded base_odds_manager.cache_ttl from config and never
used it: cached odds live for the update interval (get_odds' ttl=interval).
No core or monorepo code reads the attribute, so it is gone along with
its log line. The two consecutive `if odds_data:` blocks are one.

* refactor(backup): one table for the single-file sections

config, secrets, wifi and ytm_auth were each spelled out in create,
preview, validate and restore. _SINGLE_FILE_SECTIONS lists them once,
with the RestoreOptions flag that restores each, and all four walk it.
Restore error messages keep their wording ("Failed to restore
<file name>").

* refactor(fonts): drop FontManager's write-only state and duplicate logs

- fonts_config, font_metadata and font_dependencies were written and
  never read; the performance_stats keys font_load_times, render_times,
  total_renders and the per-call "resolve" timings
  (_record_performance_metric) likewise. get_performance_stats() reads
  only the counters that remain. Nothing in core or the plugin monorepo
  references any of them.
- A failed BDF load was logged twice, by _load_bdf_font and again by
  get_font; get_font's line is the one kept.
- Removed "NEW:" and commented-out cozette entries, the "Copy font to
  assets/fonts" comment on code that copies nothing, and local imports
  of names the module already imports. The deprecated add_font() now
  resolves assets/fonts against the install root.

The @deprecated methods stay.

* refactor(text-helper): cache loaded fonts; drop the pre-textlength fallback

TextHelper declared _font_cache, cleared it and reported its size, but
never stored anything in it. load_fonts() now keeps each (file, size)
it loads there, so clear_font_cache() and get_font_cache_stats() mean
what they say and repeated load_fonts() calls reuse the fonts.

get_text_width() no longer catches AttributeError for Pillow releases
without ImageDraw.textlength; requirements.txt pins Pillow>=12.2.
The class docstring describes what the helper does.

* docs(common): fix wrong docstrings in api_helper, permission_utils, snapshot_policy

- permission_utils called 0o2775 "sticky bit"; the 2 is setgid, which is
  what makes new files take the directory's group.
- snapshot_policy pointed at web_interface/blueprints/api_v3.py, which
  is a package now; the health check is in api_v3/misc.py.
- APIHelper.clear_cache() lost a history note and a fallback to a
  clear() method that neither CacheManager nor the testing
  MockCacheManager has. The session headers are built from
  DEFAULT_HTTP_HEADERS instead of a copy of them, and the module
  docstring says what the module offers.

* docs(sports): present-tense comments in the shared scoreboard renderers

- sports_scroll and sports_game_renderer comments that referred to "this
  PR", "the old flat 128px card" or what the renderer "previously" did
  now describe the current behaviour and its reason.
- The block explaining why non-finite settings are rejected sat above
  _score_reserve_width; it describes _center_gap_width and now lives in
  it.
- unshare_element_fonts wrapped its import of font_layout.load_truetype
  in an `except ImportError` that cannot fire inside core; the import
  stays at call time so tests can spy on the pinned loader.
- sports_card docstrings that told the history of a fix say what the
  code does.

* refactor(sports-shared): drop dead code, name the ESPN limit

- _get_weeks_data asked for limit=1000, which fetch_espn_scoreboard
  clamps to ESPN_MAX_LIMIT anyway; it now names that constant. Its
  unused `immediate_events = []` is gone.
- _get_season_schedule_dates() returned ("", "") and has no caller in
  core or the plugin monorepo.
- _should_log keeps its warning_type parameter (part of the inherited
  signature, though nothing in core or the monorepo calls it) and its
  docstring says the cooldown is shared across types.
- An unused ImageFont import is gone.

* refactor(sync): one follower-mode switch, shared panel defaults

- The class docstring said the leader sends PNG frames. Frames go over
  UDP as raw RGB; PNG is only the Vegas scroll image sent over TCP. It
  now describes both paths.
- _enter_follower_mode() replaces the two copies of "note the leader,
  switch from standalone to follower, log, write status" in the frame
  and scroll-position handlers.
- The rows/cols fallbacks use DEFAULT_ROWS / DEFAULT_COLS from
  src.display_geometry, as chain_length already did.

* refactor(style): drop _layout_axis, name the layout group title

- ElementStyleResolver._layout_axis() had no caller in core or the
  plugin monorepo.
- _element_block_from_spec checked spec['size'] was a dict again after
  size_spec already had; it reads size_spec.
- The "Layout Offsets" title written into three generated schema blocks
  is _LAYOUT_TITLE.

* docs(logo-helper): say what the placeholder draws; name the 1.5 box factor

- _create_placeholder_logo's docstring said it draws the team
  abbreviation; it draws an outlined grey box and nothing else. The
  docstring says so, and the "in a real implementation you'd want text"
  comments are gone.
- The 1.5 x panel default logo box, written out six times, is
  DEFAULT_LOGO_BOX_FACTOR.
- ImageDraw is imported with Image at the top of the module.

* refactor(logos): drop dead code and a duplicate regex in logo_downloader

- _SAFE_LEAGUE_CODE_RE was the same pattern as _SAFE_LEAGUE_RE; both
  checks use the one.
- get_logo_filename_variations reassigned the TA&M case to the list it
  already had; the function returns the two names directly.
- _get_team_name_variations() had no caller in core or the plugin
  monorepo.
- fetch_single_team's docstring was copied from fetch_teams_data; a log
  message read "for{team_id}".

* refactor: drop the Pillow<9.1 resample shim and a catch-and-reraise

- adaptive_images fell back to Image.LANCZOS/NEAREST for Pillow < 9.1;
  requirements.txt pins Pillow>=12.2. RESAMPLE_LANCZOS and
  RESAMPLE_NEAREST keep their names (src.common re-exports them).
- CacheManager.save_cache caught CacheError only to re-raise it; the
  disk write is now called directly, with the same result.

* test(api-helper): stop the real CacheManager's cleanup thread

The cache-lifetime tests built a CacheManager and left its cleanup
thread's class-wide claim on the directory in place, which broke
test_cache_cleanup_thread_ownership when it ran later in the session.
The fixture now stops the thread on teardown.

ChuckandClaude Opus 5.5 3f8edf5113 fix(logos): one hardened logo download path; shared, real HTTP headers (#612)
* fix(logos): harden the plugin logo download and share core HTTP headers

download_missing_logo / LogoDownloader.download_logo, the path the
scoreboard plugins use, read response.content with no size cap and wrote
straight to the final path, so a failed or corrupt download could be left
in place and cached as the logo. It now goes through fetch_logo: streamed
with a 10 MB cap, image/* only, decoded by Pillow, converted to RGBA once,
and moved into place atomically. A failure leaves no partial or temp file
and keeps any logo already on disk. LogoHelper._download_logo delegates to
the same code. Public signatures and return values are unchanged; saved
files are pixel-identical to before (RGBA, palette+tRNS, L+tRNS, LA, JPEG).

download_missing_logo reuses one downloader per thread instead of a new
Session per logo. Per thread rather than behind a lock: Session is not
documented thread-safe, and a lock would serialise every plugin's
downloads behind the slowest one.

Placeholders are written atomically, without the test_write.tmp probe.

The logo downloader and background data service now send the real
ChuckBuilds User-Agent from src.common.api_helper (USER_AGENT,
DEFAULT_HTTP_HEADERS) instead of a yourusername/contact@example.com
placeholder, and no longer hand-set Accept-Encoding: br (brotli is not
installed).

* fix(http): drop APIHelper's hand-set brotli encoding; LogoHelper sends the real UA

APIHelper advertised `br` though brotli isn't installed, so a server that

`LEDMatrix-Common/1.0`, the kind of User-Agent ESPN has been rejecting.

ChuckandClaude Opus 5 69d408b321 feat(core): one per-element display-customization framework, wired into the web UI (#566)
* fix(sports): rebuild un-shared faces through the pinned layout engine

unshare_element_fonts re-instantiates a duplicate font face so two
elements can be told apart by id(). It did so through bare
ImageFont.truetype, which takes PIL's default layout engine rather than
the one src/common/font_layout.py pins. Raqm and Basic disagree on
fractional advances -- that disagreement is the reason the pin exists,
having broken golden images across machines -- so a rebuilt face could
measure differently from the shared face it replaced, on any host where
Raqm is installed.

These were the only two call sites in src/ bypassing the pin.

The guard asserts that the rebuild goes through the pinned loader rather
than comparing engine values: where Raqm is absent, bare truetype returns
BASIC anyway, so an engine comparison passes whether or not the pin is
honoured. The first draft of this test did exactly that and passed with
the bug reintroduced.

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

* refactor(web): drop the two dead client-side config-form renderers

generateConfigForm and generateSimpleConfigForm (580 lines) were defined
on the Alpine component and never called: server-side Jinja replaced them,
as pages_v3.py:641 records. Nothing in any template invokes them -- there
is no x-html in the templates and no bracket access on the component.

They carried their own x-widget dispatch, which made them an active trap:
the next person adding a widget would reasonably think both renderers
needed updating.

plugins/config_manager.js (PluginConfigManager, 133 lines) goes for the
same reason -- loaded on every page from base.html, referenced only by
itself and by an archived doc.

Kept, having checked them: widgets/example-color-picker.js is the worked
example docs/widget-guide.md points plugin authors at, and
widgets/plugin-loader.js is the client half of a documented feature
(manifest-declared plugin widgets) whose server route is missing --
soccer-scoreboard already ships a widgets/custom-leagues.js that this
loader is meant to fetch. That is an unfinished feature to complete, not
dead code to delete.

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

* feat(web): serve plugin-declared widgets, and actually ask for them

LEDMatrixWidgets.loadPluginWidget has always fetched
/static/plugin-widgets/<plugin>/<widget>.js, and docs/widget-guide.md has
always documented that path, but nothing served it. soccer-scoreboard has
shipped a 17KB widgets/custom-leagues.js since August that could never
load. Both halves were missing, not just the route:

- serve_plugin_widget serves the script from the plugin's widgets/
  directory as text/javascript. The manifest is the allowlist -- only a
  widget the plugin declares is reachable -- so installing a plugin does
  not publish everything it ships. Path handling mirrors the sibling
  serve_plugin_web_ui: allowlist regexes, os.path.basename, resolve() +
  relative_to() containment, and the ledmatrix- prefix fallback. The
  declared script name is guarded too, since it comes from the plugin
  rather than the request.

- The config form never requested one. Its x-widget dispatch is a
  hardcoded list of core widget names, so a plugin's own widget fell
  through to a plain text input. An unrecognised x-widget on a string
  field now asks ensureWidget() for it. The text input stays as the
  fallback and is removed only once the widget has actually rendered, so
  a missing or broken widget costs the user an editor rather than their
  configured value on the next save.

- manifest_schema.json gains "widgets", so the declaration is validated
  rather than merely tolerated by additionalProperties.

Verified in a browser against the real partial: a declared widget loads,
registers and renders, and its field posts exactly one value; a field
whose widget 404s keeps its text input and still posts its value.

Not addressed: loadPluginWidgetsFromManifest still has no caller. The
per-field ensureWidget path is lazier and is what the form now uses, so
that bulk helper is dead weight -- worth removing, but left alone here
rather than inventing a call site for it.

Known limitation, documented: only string-typed fields take this path.
object/array/boolean/number fields and enums are dispatched by the
template's own branches, which still only know core widgets.

* fix(element-style): a wrong-size BDF now keeps its font, not its size

BDF fonts are fixed-size bitmap strikes: FreeType accepts only the pixel
size baked into the file and raises for anything else. 32 of the 35
shipped fonts are BDF, so a size picked in the web UI usually is not a
valid strike -- and load_font caught that failure with its generic
"unloadable font" handler, which substitutes PressStart2P. Asking for
5x7.bdf at size 10 therefore rendered a completely different typeface,
silently.

It now falls back to the file's own native size instead, which is what
SportsCore._load_custom_font_from_element_config has always done. The
native size is read via FontManager._read_bdf_native_size rather than a
fourth copy of that parser, matching how core.py already delegates.

Also here, because they are the same code path:

- native_bdf_size() is exposed for the web UI, which needs to know when a
  size field can take effect at all. None means "free choice".
- ElementStyle.font_size now reports the size actually realised rather
  than the one requested. Callers lay out from it, and reserving space
  for a size nothing was drawn at is how this surfaces.
- The module font cache is a bounded LRU (256) instead of an unbounded
  dict. The display process runs for weeks and every config save can add
  a (font, size) pair; every other hot cache in the codebase is bounded
  this way.

Untouched configs are unaffected: the shipped classic fonts are the three
TTFs, so nothing was hitting the substitution path by default.

* feat(element-style): per-mode style and offset overrides

Lets one element be styled differently per situation -- a scoreboard's
live / upcoming / recent cards, weather's current / hourly / daily
screens -- under customization.modes.<mode>.

The mode is bound at construction rather than passed per call. That is
what makes this cheap to adopt: SportsUpcoming and SportsRecent are
already separate instances with distinct SKIN_MODE values, so binding
once makes every existing style()/offset_value() call site mode-aware
without editing any of them. A per-call mode argument exists for the rare
host that renders more than one mode.

The two layers answer different questions, deliberately:

- The base layer keeps the existing "differs from the schema default"
  rule, because the save flow writes the full default object into
  config.json whether or not the user touched it.
- A mode layer is pure override -- its fields default to None, so
  presence is intent. Nothing writes into it unasked, so there is nothing
  for the stricter rule to protect against.

None therefore means inherit, and has to stay distinct from 0: a mode
y_offset of 0 means "sit at the base position", not "no preference".
This is the same distinction scroll_card.switch_* draws with "inherit".

A malformed mode value falls back to the resolved base value rather than
to the caller's default -- caught by the degradation tests, which is what
they are for: resolving the mode first let one bad string in a mode block
silently discard a good base offset.

With no modes block, and for every existing caller, resolution is
unchanged.

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

* feat(element-style): declare per-mode overrides in config_schema.json

A plugin adds "x-style-modes": ["live", "upcoming", "recent"] alongside
its x-style-elements declaration and gets a customization.modes.<mode>
group per mode, with every field of every declared element repeated as an
override.

Those override fields are typed nullable and default to null, which is
the whole trick. The save flow writes schema defaults into config.json
wholesale, so giving a mode field the base element's default would make
every mode a frozen copy of the base the first time a user pressed Save,
and the base would stop reaching them. Null means inherit. The mutation
test for this is explicit: with concrete defaults, a base font_size of 14
resolves as 10 with user_forced set.

min/max from the declaration carry into the mode blocks, so an
out-of-range override is rejected by validation rather than clamped
silently at render time.

Also: the emitted font field now carries "x-widget": "font-selector". The
widget already shipped and the config form already allowlisted it -- the
hint was simply never emitted, so the field rendered as a bare text box
that the user had to type a font filename into.

Verified through the real SchemaManager path -- load_schema, defaults
extraction, merge_with_defaults, validation, then resolution -- rather
than against a hand-built dict, since the thing at risk is what that
pipeline does to a null.

* fix(web): render the config form from the schema the save route validates

The form read config_schema.json with a raw json.load while
api_v3.save_plugin_config went through SchemaManager. Those are not the
same schema: SchemaManager applies expand_style_elements, which turns a
compact customization.x-style-elements declaration into the per-element
blocks the form knows how to render.

Without it, that customization object has an x-style-elements key and no
"properties", so the template's object branch matched nothing and the
section rendered as empty space -- while saving still validated against
the expanded shape. of-the-day ships the compact form, so its
customization section has been invisible in the web UI.

pages_v3 gains a schema_manager the way it already has config_manager and
plugin_manager. use_cache=False matches the save route, so an edited
schema is not served stale during plugin development. The raw read stays
as a fallback for callers that register this blueprint without one.

Checked before making the change: load_schema does nothing here except
read, validate and expand -- inject_skin_selector is a separate method it
does not call -- so this is not a behaviour change for schemas without
the declaration.

The test pair renders the same compact schema with and without a
SchemaManager, so it documents exactly what was broken as well as what is
fixed.

* feat(web): style-editor widget -- a row per element instead of 65 accordions

Rendered element by element, a realistic scoreboard's customization block
is 65 nested sections, and reaching one per-mode font size takes five
levels of expanding. The widget collapses that to one compact row per
element -- font, size, colour, X, Y -- with a tab per declared mode.

It emits ordinary inputs under the same dotted names the generic renderer
would produce, so the save/validate/merge pipeline is untouched: no hidden
JSON blob and no new server-side parsing. It is driven entirely by the
schema block it is handed, so fields added to the schema later appear
without editing the widget. If it fails to load or throws, the generic
nested rendering it replaces is left in place.

Fixing two things the save path got wrong for nullable fields, found by
posting what the widget actually emits:

- The indexed-array recombiner (text_color.0/.1/.2 -> one list) compared
  the declared type to the string 'array', so a per-mode colour, typed
  ["array", "null"], was never reassembled and failed validation on save.
  _parse_form_value_with_schema had the same comparison.
- A blank nullable field became [] rather than None, which then failed the
  minItems the colour array declares. Null is the inherit sentinel, so it
  has to survive.

And two things the widget itself got wrong, found by looking at it:

- An unset base control fell back to the select's first option, so an
  untouched scoreboard claimed every element used 10x20.bdf -- and the
  size box then locked itself to that bitmap font's fixed size. Base
  controls now show the schema default; mode controls stay blank, because
  blank there means inherit.
- Elements arrived alphabetised (Detail and Odds above Score). Flask's
  JSON provider sorts keys, so declaration order has to be stated
  explicitly; expand_style_elements now emits x-propertyOrder, which the
  generic renderer already honoured too.

Size is disabled and shown as fixed for a bitmap font, using the
scalable/native_size the font catalog now reports.

* feat(element-style): visibility, alignment and scale per element

Completes the customization vocabulary: hide an element, align it, and
resize a logo, alongside the font/size/colour/offset that already existed.
All three per mode.

They resolve to "change nothing" until the user asks for something -- True,
None and 1.0 -- rather than to whatever the schema declares. That is the
same invariant the font fields keep: a caller that honours them still
renders an untouched config exactly as it did before they existed. A
schema default therefore does not count as a choice, which matters because
the save flow writes that default into config either way.

scale sits in the layout block with the offsets rather than in the element
block, because it is geometry: a logo has a scale and no font. The widget's
columns come from the schema, so a logo row shows visibility, offsets and
scale and no empty font cell.

Two bugs found by the tests rather than by reading:

- A nullable enum needs null in its enum list, not just in its type. The
  mode copy of `align` defaulted to null and then failed its own schema, so
  a plugin declaring any enum field with modes could not save at all. Six
  tests failed on this before any of them reached what they were testing.
- defaults_from_schema only ever extracted font/font_size/text_color, so
  the schema defaults for the new fields were invisible to the resolver and
  a declared default read as a user choice.

Widget: the table scrolls horizontally and pins the element-name column.
Nine columns do not fit the config panel, and clipping them hid the offsets
entirely while scrolling them made every row anonymous.

* feat(element-style): resolve elements under the names plugins actually use

Two naming conventions collided as the scoreboards grew. Counted across
the published schemas: the style block names elements with a _text suffix
(score_text, status_text, detail_text), while the layout block mostly uses
the bare noun (score, date, time, odds) -- except status_text, which kept
the suffix in seven plugins and lost it in two. records vs record splits
seven to two the same way.

A lookup now tries the exact name first and then the spellings that mean
the same thing. Exact-first is what makes this inert for any config that
already matches; the aliases only decide cases that resolved to nothing
before.

This is also what makes migrating to the compact declaration form safe.
That form uses one key for both blocks, so a scoreboard adopting it asks
for layout.score_text while its users have layout.score saved -- without
the aliases, every offset they had dialled in would silently become 0.

Applies to the style block, the layout block, the schema defaults and the
per-mode overrides, since the drift shows up in all four.

Not attempting to canonicalise on write: renaming keys in config.json
would break the plugins still reading the old spelling from their own
bundled code, and the drift costs a dict miss rather than correctness.

* feat(plugins): BasePlugin.styles -- per-element styling every plugin inherits

Adopting the element-style system meant repeating three things in every
plugin: a guarded import, finding its own config_schema.json, and
rebuilding the resolver when on_config_change swapped the config dict.
This is those three things once, on the class all 45 plugins already
inherit from.

    title = self.styles.style('title_text',
                              classic_font='PressStart2P-Regular.ttf',
                              classic_size=8, classic_color=(255, 255, 255))

The classic_* arguments are the adoption contract: with nothing configured
they come back verbatim, so a plugin that switches to this renders exactly
as before until a user changes something.

A plugin with one instance per display mode sets STYLE_MODE on the class
and every existing lookup becomes mode-aware without a call site changing
-- which is the point of binding the mode to the resolver rather than
passing it per call. styles_for() covers a plugin that renders several
modes from one instance.

Schema discovery reads the concrete class's own module rather than this
file, because this file lives in src/plugin_system where no plugin schema
exists -- the same trap SportsCore._config_schema_path documents. The
first mutation test for that passed anyway: an installed plugin's module
directory and its entry under plugins_dir are the same path, so the test
could not tell the two apart. The case where they diverge is a plugin
symlinked in for development, and the test now forces that shape.

Getting discovery wrong is silent rather than loud: with no schema the
resolver has no defaults to compare against, so every configured value
reads as a deliberate override and the plugin quietly stops honouring its
own shipped styling.

* feat(element-style): adopt hand-written customization blocks, and widen the font list

Nineteen plugins spell their style elements out longhand instead of
declaring them -- football's block is 701 lines for seven elements -- and
predate this system entirely. Core now recognises that shape, so they pick
up the row-per-element editor and the real font picker on a core update
rather than on a plugin release. Checked against every published schema:
21 plugins adopt, and the defaults of each still validate against the
schema generated for it.

Detection requires *every* field in a block to be one this system
understands. A looser "has at least one style field" rule sweeps in
baseball's `count`, which carries a text_color beside geometry that means
nothing here. That distinction took three attempts to test: the first two
assertions passed under both rules, because an over-eager rule leaves a
fontless block looking untouched and only surfaces as an extra row in the
editor.

The hardcoded font enum is replaced rather than extended. Football lists
five of the thirty-five installed fonts, which is why a font a user
uploads can never appear in one. It is not a curated safe set -- it omits
some twenty other faces that fit the declared size cap just as well -- it
is the fonts that happened to exist when it was written.

Widening it does need a guard, though, and not the one the schema already
has: a bitmap font ignores font_size and renders at its size baked into
the file, so `maximum: 16` cannot stop a 27px face. The picker now filters
out fixed-size fonts taller than the element's own declared ceiling, which
drops exactly the four that would overflow a 32px panel and keeps the
other thirty.

Per-mode overrides stay opt-in: core cannot invent a plugin's display
modes, so `x-style-modes` remains the one line that unlocks them. Their
layout half covers every positionable element rather than only those with
a style block -- the two namespaces do not line up in a hand-written
schema, and football positions six things (logos, timeouts, possession)
that have no style block at all.

* refactor(web): remove the two Fonts-tab panels that reported invented data

"Element Font Overrides" let a user configure an override, showed a
success toast, and changed nothing. All three endpoints behind it were
stubs -- GET returned a hardcoded {}, POST and DELETE returned success
without calling anything -- each marked "This would integrate with the
actual font system".

Wiring them to FontManager would not have fixed it. The machinery there is
real (_load_overrides/_save_overrides persist config/font_overrides.json,
resolve_font applies them, and the countdown plugin genuinely consumes
it), but the panel's element dropdown offered eleven invented keys --
nfl.live.score, clock.time, weather.current -- that no plugin has ever
read. An override saved against one of those would have persisted
correctly and still done nothing.

"Detected Manager Fonts" goes for the same reason. It claimed to show
"fonts currently in use by managers (auto-detected)"; its own comment said
"we'll simulate this", and it listed every font in the catalog with a
hardcoded usage_count of 1 -- the panel beside it, with fabricated
numbers attached.

Per-element font choice now lives in each plugin's own config editor,
against the elements that plugin actually has, and covers size, colour,
offsets, visibility, alignment and scale rather than family and size.

Kept: the font library (upload, preview, delete), which works, and
/fonts/tokens, which is a stub but genuinely feeds the preview's size
dropdown. FontManager's override methods are untouched -- countdown uses
them.

Verified in a browser with the tab's JS running: no console errors, 35
fonts listed, upload and preview intact. Removing the panel meant unwiring
it from populateFontSelects too, which would otherwise have bailed out
early on the missing select and left the preview dropdown empty.

* refactor(sports): one reader for element colours and layout offsets

There were two copies of the per-element colour read and three of the
layout-offset read. They had already drifted -- the scroll-card renderer
carries a comment about having ignored offsets its own schema advertised
-- and each new capability had to be added to all of them or silently work
in some places and not others.

All of them now go through src.element_style, which is what carries the
alias handling and the per-mode lookup. That lands immediately for the
nine plugins importing these modules: a scoreboard asking for `score_text`
offsets finds the `layout.score` its users configured, and a Live instance
resolves its own colours through SKIN_MODE without any call site passing a
mode.

_normalize_color learned "#RRGGBB" in the process. The scoreboards' own
readers have always accepted it, so the shared one had to, or consolidating
would have quietly dropped a form users' configs may hold. _coerce_offset
picked up the non-finite guard the scroll-card reader had and the other two
did not.

_get_layout_offset is promoted onto SportsCoreSharedMixin. Each plugin
still carries its own copy in its bundled sports.py, which wins by MRO --
so adopting this is a deletion in the plugin, and until that deletion
nothing changes for it.

Note for whoever runs the suite next: test_display_dirty_tracking.py is
order-dependent. Fifteen of its tests failed in one full run and passed in
the next with no change in between, and pass in isolation. Pre-existing,
unrelated to this, but it makes a full-run diff untrustworthy until it is
fixed.

* docs(changelog): record the element-style work under Unreleased

This file's own preamble asks for it: a plugin may delete its bundled
fallback copy of a core module only when its manifest floors on the first
release that shipped that module, which requires the additions to be
recorded here against a version.

Names a plugin can now import and floor on -- the stateless layout_offset
and element_color readers, alias_keys, native_bdf_size, the resolver's mode
binding, BasePlugin.styles, and the promoted
SportsCoreSharedMixin._get_layout_offset -- plus the schema and web-UI
changes, the four fixes and the three removals.

* fix(fonts): log the BDF native-size read failure instead of swallowing it

The bdf-native-size lookup in get_fonts_catalog() caught any exception
and silently discarded it. Every other guarded read added in this PR
(the manifest parse in _declared_widget_script, the SchemaManager
fallback in _load_plugin_config_partial) logs before falling through
to the same degraded behavior. This one didn't, which is the shape a
silent-exception-swallow lint rule flags. Behavior is unchanged --
native_size still comes back None -- but a corrupt or unreadable BDF
file now leaves a trace.

Verified: font-related tests (140) and the full suite still pass,
with only the 2 pre-existing Europe/Kiev/Asia/Calcutta tzdata-alias
failures already present on origin/main.

* fix: address CodeRabbit findings on the style-editor/font-selector PR

- Fix _load_font_sized double-wrapping the (font, size) tuple on the
  missing-font path, which handed callers a tuple instead of a font.
- Fix _set_nested_value skipping an explicit None when the key already
  existed, which silently kept stale overrides when a user cleared a
  nullable per-mode field or blanked all channels of an indexed color.
- Preserve BDF scalable/native_size metadata through fetchFontCatalog's
  catalog-format mapping so maxFixedSize filtering actually applies.
- Stop caching an empty array on a failed font-catalog fetch so a later
  call can retry instead of being stuck with the failed result.
- Keep a saved font selected in the style editor even when it no longer
  fits a newly declared maxFixedSize, instead of silently deselecting it.
- Don't drop in-progress user edits to fallback fields when a plugin
  widget finishes loading asynchronously and takes over the form.
- Tighten the removed font-override endpoint test to assert 405, not
  just != 200.

* fix(web): a partial save no longer switches off checkboxes it never showed

An HTML checkbox posts nothing when unchecked, so the save route walked the
schema and forced every boolean missing from the form to False. That is right
for the rendered form and wrong for every other caller: a script, the MQTT
bridge or a curl against the documented endpoint never rendered a checkbox, and
reading its silence as "all off" turns a one-field save into a mass disable.

Found on hardware. Posting four customization.* keys to a live device switched
off nfl.enabled, ncaa_fb.enabled and every display-mode toggle in one request.

The form now reports the top-level sections it drew (__rendered_section), and
inside those an absent checkbox still means unchecked -- including a section
whose only fields are checkboxes that are all off, which no heuristic could
recover. A post with no marker only touches objects it actually posted a field
from. Meta fields are dropped before form keys are treated as config paths,
because unknown keys are otherwise written straight into config.json.

* feat(sports): resolve element colour by name, and honour visible/align/scale

Two of the three gaps this framework shipped with.

Colour by name. A draw resolved its colour by comparing the *identity* of the
font object it was handed, which cannot tell two elements apart when they share
a face -- so those draws went out white. Every bitmap font is in that case,
because a freetype.Face cannot be re-instantiated to un-share it, which is how
an element rendered in any of the 32 shipped BDF fonts silently lost a colour
its picker had offered all along. _draw_text_with_outline now takes
element="score_text" and reads the colour by name; the identity path remains
for un-annotated callers, but narrows before giving up -- one configured colour
among the sharers is the only thing the user can have meant.

Visible, align and scale. The resolver has understood these since the
framework landed and nothing consumed them: an element could be marked hidden
in the web UI and still render. Adds the stateless readers, the mixin
accessors, and a scale parameter on the one shared logo-sizing seam (keyed into
the cache, so two elements scaled differently cannot be served each other's
image). Naming an element in a draw also honours its visibility.

Untouched configs are unaffected: every new parameter defaults to today's
behaviour, and all ten affected plugins render pixel-identically to main across
every harness size.

* docs(plugins): how to declare styleable elements; harden the widget's lookups

The plugin-author guide for the compact x-style-elements declaration -- what
each key does, how to read values back without breaking the "user-forced only
when it differs from the default" rule, and why a hand-written block needs no
changes to be adopted.

Also clears the static-analysis findings on style-editor.js. Every lookup in
that file is keyed by something out of a schema or a saved config, so a key of
__proto__ or constructor would walk the prototype chain and hand back a
function instead of a schema; reads now go through an own-property helper. The
panel registry became a list, and the flagged vars moved to their function
roots.

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

* fix(web): clear the remaining static-analysis findings

Five, all on lines this branch touched.

The Python one is not a new defect: _set_missing_booleans_to_false's first
parameter was always named `config`, which shadows the `config` submodule
imported for its side effects at the bottom of this module. Editing the
signature simply put the existing warning on a changed line. The parameter is
the plugin's config dict, so `plugin_config` is what it should have been called
anyway; callers pass it positionally and are unaffected.

The JavaScript ones are the object-injection rule firing on reads keyed by
data. own() now goes through a property descriptor, so the one unavoidable
data-keyed read is no longer a computed member access; at() consumes its path
instead of indexing it; and the column set is a Map, which has no prototype to
pollute and needs no guarded reads at all.

Verified the widget still renders identically against football's real schema:
29 element rows, all four mode tabs, values populated, no console errors.

ChuckandClaude Opus 5 28bc79566f fix(logo): remember a missing logo instead of re-warning every rotation (#548)
* fix(logo): remember a missing logo instead of re-warning every rotation

load_logo() stat'd the path and logged a WARNING on every call, and the
positive cache never covered it because a miss returns None and caches
nothing. A file that is simply not there therefore produced one warning per
rotation for as long as the process ran -- measured on a live rig at 114 lines
in 24 hours for a single missing ticker icon, for a file nobody was going to
add.

Misses are now remembered for 10 minutes: warn once, then return None without
touching the disk. Bounded rather than permanent because logo_downloader
writes logos at runtime, so a file that appears later must still be picked up
without a restart. Downloads through load_logo_with_download() clear the entry
outright -- load_logo() consults the miss record before it stats the disk, so
without that a freshly downloaded logo would stay invisible for the whole
window.

This is in the core rather than in ledmatrix-stocks, where it was found, so
every plugin that goes through LogoHelper gets it.

_cache_order stays a list. Swapping the pair for an OrderedDict would shave an
O(n) scan per cache hit, but n is capped at cache_size (100 by default) and
test_logo_helper.py pins the current structure; not worth the churn.

* fix(logo): make the miss TTL longer than the rotation it is meant to outlast

Deployed the previous commit to a live rig and measured it: no change at all.
"Logo not found for VOO" stayed at ~6 lines an hour, exactly the baseline.

The TTL was 600s and the display rotation is ~618s, so every recheck expired
just as the plugin came round again and the negative cache never once got to
suppress a warning. The fix was correct in shape and useless in practice,
which only measuring on the rig would show.

An hour instead. That is safe because the TTL is not the main way an entry
clears: load_logo_with_download() drops it the moment a download succeeds and
clear_cache() drops all of them. The TTL only covers a file that appeared some
other way -- someone copying one in by hand -- and waiting up to an hour for
that, or restarting, is a fair trade for not re-warning about a file nobody is
going to add.

The general lesson is in the comment: a TTL has to be long relative to the loop
that does the asking, not merely "a while".

ChuckandClaude Opus 5 92f9d06af9 fix(logos): stop a failed download pinning a team to a grey box forever (#512)
* fix(logos): stop a failed download pinning a team to a grey box forever

When a logo download fails, create_placeholder_logo writes a 64x64 grey PNG
under the *real* logo's filename. Every later call then hits
`if filepath.exists(): return True` and reports success, so the real logo is
never attempted again. One transient failure -- no network at boot, ESPN
blipping -- permanently costs that team its logo.

This is not hypothetical. Five of the eleven cached AFL logos in my checkout
were 384-byte stubs written in a single bad minute, and they had stayed that
way ever since; the scoreboard rendered COLL, FRE, NMFC, PORT and SYD as grey
text boxes on every card.

Placeholders are now stamped with a `ledmatrix_placeholder` PNG text chunk
carrying their creation time, and `is_placeholder_logo` recognises them. It
also matches on the placeholder's exact geometry and background colour, so the
stubs already sitting on users' disks are picked up too -- without that, this
fix would only help teams whose logos break in future. Verified against the
real stubs: all five detected, all six real logos untouched.

`download_missing_logo` now treats an existing placeholder as the failed
download it is and retries, rather than as a satisfied request. The retry is
rate-limited to PLACEHOLDER_RETRY_SECONDS (6h) so this does not trade a
permanent grey box for an ESPN request every frame; a failed retry rewrites the
placeholder, restarting the clock. The age comes from the stamp rather than
mtime, so a backup restore, an rsync, or a permissions script cannot silently
reset it.

`download_missing_logos_for_league` gets the same treatment -- a bulk pass is
exactly where a previously failed logo should get another chance -- and
`LogoHelper.load_logo_with_download` no longer accepts a stale placeholder as a
cache hit. That import is lazy and guarded so the module still works against a
core build predating the marker.

`LogoHelper._create_placeholder_logo` needs no change: it returns an in-memory
image and never writes it to disk, which is the behaviour this bug argues for.

Tests cover marked and legacy-unmarked detection, the two false-positive cases
(a real 500x500 logo, and a 64x64 image that is merely the same size), the
retry, the rate limit, and that the age survives an mtime touch.

* fix(logos): address review — unify eligibility, invalidate cache, restart back-off

Three findings from the review on #512, all confirmed against the code:

1. The three download sites each had their own idea of "already have it".
   download_missing_logos_for_league() retried *any* placeholder, ignoring the
   back-off entirely, while download_all_ncaa_football_logos() was never
   updated and still skipped placeholders forever. They now share one
   should_attempt_download(), which also covers force_download, so the sites
   cannot drift apart again. download_missing_logo() reads through the same
   helper.

2. LogoHelper.load_logo_with_download() answered from the in-memory cache
   before touching the disk, so after a stale placeholder was successfully
   replaced the *cached placeholder image* was still returned -- the real logo
   would not have appeared until the process restarted. The cache entry for
   that file (every size of it) is now dropped after a successful download.

3. A failed retry left the stale placeholder on disk with its old timestamp,
   so the next call saw it as stale again and retried immediately: a download
   attempt per call, which is precisely what the back-off exists to prevent.
   refresh_placeholder_timestamp() restamps it, and the helper calls that on
   the failure path. It refuses to touch anything that is not a placeholder.

Tests cover both bulk loops in both directions (fresh placeholder skipped,
stale one retried), the eligibility rule including force_download, the
timestamp refresh, and the two LogoHelper paths -- including that a
freshly-downloaded logo is actually what comes back rather than the cached
placeholder.

Two of the new bulk-loop tests initially passed for the wrong reason: the
fetch_teams_data stub returned {}, which is falsy, so the loops bailed before
reaching the eligibility check at all. Fixed to return a truthy payload.

Re-verified end to end: with both halves in place, rendering the AFL scoreboard
took FRE.png from a 362-byte stub to a 12,928-byte logo.

ChuckandClaude Opus 5 10e75b977f Cover the next tier of untested modules and endpoints, and fix the 43 bugs that surfaced (#459)
* test(sync): cover the display sync protocol, and fix what that surfaced

DisplaySyncManager had no tests at all — it appeared in the suite only as
a MagicMock() stand-in, so none of its framing, handshake, or socket
handling was ever exercised. Writing that coverage surfaced three bugs.

Both receive loops caught the generic Exception and immediately retried.
A socket left in a bad state raises on every call, so the thread spun at
100% CPU logging the same line; the reverted-code run of the new
regression test takes 24 seconds where the fixed one takes 0.2. Both now
back off briefly before retrying.

The follower dispatched on `data[:8] == _RAW_MAGIC or len(data) > 512`.
That size threshold is not part of either wire format: a control message
over 512 bytes — a hello_ack carrying a long incompatibility error, for
instance — went to the image decoder and was dropped, and a raw frame
under 512 bytes went to the JSON parser. Both formats are already
self-describing, so dispatch on the magic prefix and treat a JSON parse
failure as the legacy unmarked PNG, with the shared frame bookkeeping
factored into _handle_received_frame().

_oversized_frame_warned was created on first use through
getattr(self, ..., False) rather than in __init__, alone among the
instance attributes.

75 tests: role parsing, the hello compatibility matrix, watchdog

* test(logos): cover LogoHelper, and stop bad downloads poisoning the cache

Nothing in test/ referenced logo_helper.py, so its caching, resizing and
download-fallback logic was entirely unexercised. Two bugs surfaced.

_download_logo wrote response.content to disk with no size limit and no
check that the bytes were an image. A logo URL is remote input, so the
response chose how much went into the assets directory; worse, an
undecodable one stayed there, and because load_logo() only reports the
decode failure and returns None, every later call re-read the same
corrupt file. The download path never retried, so a single bad response
made a logo permanently blank rather than falling back to the
placeholder. Cap the response, verify it decodes, and delete it if not,
which lets the existing fallback in load_logo_with_download do its job.

get_cache_stats() divided by self.cache_size with no guard, so a helper
built with cache_size=0 raised ZeroDivisionError from what is only a
stats call.

37 tests: size-qualified cache keys, LRU eviction and refresh, the four
load_logo_with_download paths, download permissions and timeout,
placeholder generation, and the abbreviation normalizer — including a
test pinning its deliberate divergence from
LogoDownloader.normalize_abbreviation, since logo filenames on existing
installs depend on both behaviors staying put.

* test(web): cover the error and response builders, and stop dropping empty values

errors.py and error_handler.py's response builders had no direct tests,
though every API response passes through them. Two bugs surfaced.

WebInterfaceError set suggested_fixes with `or`, so a caller passing []
to mean "I have no suggestions for this one" got the default list
instead. Only None should fall back.

create_success_response gated `data` on `is not None` but `message` and
`metadata` on truthiness, so an explicitly-passed "" or {} vanished from
the response while 0 and False survived — the response shape depended on
the value. api_helpers.success_response() then re-gated metadata the same
way, which is the path every api_v3 endpoint actually calls, so fixing
only the inner function would have changed nothing observable. Both now
use `is not None`.

That wrapper also merged request timing into the caller's own metadata
dict in place. A caller reusing a dict across requests would accumulate
previous responses' timings; it now copies before adding.

79 tests: category inference for every error code, mapped vs fallback
suggestions, the JSON shape including which keys are omitted when empty,
exception-to-code inference, and the success/error builders end to end.
Two behaviours are pinned as deliberate rather than fixed: an empty
context stays out of the response body, and from_exception's `message`
is the fixed per-code string, never the raw exception text.

* test(web): cover the input validators, and close three holes in them

validators.py had tests for dedup_unique_arrays only; the other eight
functions were untested. Three bugs surfaced.

validate_image_url checked for '..' only inside its relative-path
branch, so http://host/../secret passed validation while /../secret was
rejected — the traversal check now runs before the branch split, which
is where a safety check on the whole URL belongs.

validate_file_upload lowercased the uploaded filename's extension but
compared it against the caller's list verbatim, so allowed_extensions of
['.TTF'] rejected every valid .ttf file. Both sides are lowercased now.
The one in-tree caller passes lowercase already, so this only widens what
future callers can hand it.

validate_numeric_range accepted True and False, because bool subclasses
int; a boolean then compared as 1 or 0 against the range and validated
cleanly. Excluded explicitly, matching how base_plugin.py already handles
the same trap for display_duration.

84 tests. Two behaviours are pinned rather than changed:
sanitize_plugin_config deliberately does not HTML-escape strings, since
escaping at this layer would store the escaped form in config.json — the
docstring said "prevent injection", which read as a promise it does not
keep, and now says what it actually does. validate_font_awesome_class's
second 'fa-' check is unreachable behind its own regex; harmless, so
characterized rather than removed.

* test(api): cover wifi and registry endpoints, and fix bodyless POSTs

The /wifi/* routes drive the host's real networking and the registry
routes reach GitHub, and neither had endpoint-level tests. Covering them
surfaced a bug affecting six endpoints.

Six handlers read their body as `request.get_json() or {}`. The `or {}`
says every field is optional and a missing body should fall back to
defaults — but get_json() without silent=True raises UnsupportedMediaType
when there is no JSON Content-Type, and it raises before `or {}` is ever
evaluated. Each handler's catch-all then reported that as a 500. So
POSTing with no body — what curl sends by default, and what a fetch()
without options sends — failed on /plugins/store/refresh,
/display/on-demand/start, /plugins/config/reset,
/plugins/of-the-day/json/delete, /plugins/{id}/limits and
/plugins/authenticate/spotify. The shipped UI always sends a JSON object,
which is why this stayed hidden.

All six now use silent=True. test_api_v3_optional_body.py covers the
affected endpoints and adds a source check, since the combination of
`or <default>` with a non-silent read is self-contradictory wherever it
appears and is easier to catch by inspection than by exercising each
endpoint by hand.

Also adds test/_api_v3_test_helpers.py: the blueprint holds its managers
on a module-level singleton rather than in Flask app state, so a test
that mocks them leaks into every later test unless the originals are
restored. The existing _make_client() does this for unittest classes;
this is the pytest-fixture equivalent, for the five suites still to come.

69 endpoint tests: connect/disconnect/AP/radio including the string-aware
boolean coercion these endpoints deliberately use, the radio's
lockout-refusal path, registry refresh and fetch-from-URL, and a guard
that WiFiManager is never constructed for real.

* test(api): cover the music auth endpoints, and always clean up the wrapper

The Spotify step-2 handler writes a Python wrapper script to a temp file
with the user's redirect URL embedded in its source, then executes it.
That is the most dangerous shape in the blueprint and had no tests.

The wrapper was deleted in the success/failure branch and again in the
TimeoutExpired handler. Any other failure from subprocess.run — no
interpreter, a fork failure, an interrupted call — reached neither, and
left a world-readable temp file containing the user's redirect URL on
disk. Cleanup moves to a finally block, which is what "delete this
whatever happens" should have been from the start.

The injection tests are the point of this file. Eight adversarial
redirect URLs (embedded quotes, backslashes, newlines, triple quotes, a
full `"; import os; os.system("id"); "`) are each pushed through the
endpoint and the generated wrapper is parsed with ast: it must still be
valid Python, the URL must still be a single string literal bound to
redirect_url, and no os.system call may appear anywhere in the tree.
json.dumps holds up, but nothing was checking that it does.

40 tests. Also pins that the two endpoints are not symmetrical despite
the matching names — only Spotify has a two-step flow and a wrapper; YTM
runs its script directly — so a later change does not "restore" a parity
that was never there.

* test(api): cover the credentials upload, and stop it hoarding secrets

The endpoint that receives the user's Google OAuth credentials file had
no tests. Two bugs surfaced.

The OAuth-shape check ran inside `except Exception: pass`. A JSON
document that parses but is not an object — a bare 42, true, null, a
list — makes `'installed' not in creds_data` raise TypeError, which the
bare except swallowed, and the file was then written out as
credentials.json regardless. The check now decides the outcome instead
of being advisory, so anything not credentials-shaped is refused up
front rather than failing later inside the calendar plugin.

Every overwrite copies the old file to credentials.json.backup.<ts> and
nothing removed them, so a user who re-uploaded ten times had ten
complete sets of OAuth client credentials sitting in the plugin
directory, indefinitely. Keep the newest five. Pruning is housekeeping,
so a backup that cannot be removed logs and leaves the upload alone.

27 tests: size and extension limits, malformed JSON, the shape check,
0600 permissions on the written file, backup-on-overwrite, and pruning
including the repeated-upload case that stays bounded.

* test(api): cover the install endpoints, and make 14 dead guards reachable

/plugins/install and /plugins/install-from-url were tested only at the
PluginStoreManager layer, so the route logic — the queue-versus-direct
branch, schema invalidation, discovery, state and history recording — was
unexercised.

Covering them surfaced the wider form of the body-parsing bug fixed for
the `or {}` handlers in the previous commit. Fourteen handlers read
`data = request.get_json()` and immediately guard with `if not data:
return 400, 'No data provided'`. That guard cannot run: get_json()
without silent=True raises UnsupportedMediaType for a request with no
JSON body, so the catch-all answered 500 "an error occurred; see logs
for details" where the handler plainly meant to answer 400 and say
which field was missing. Every one of these endpoints told a caller who
simply forgot the body to go read the server logs.

All fourteen now use silent=True, so the guard each author already wrote
is the one that runs. This covers /config/raw/main and /config/raw/secrets
among them, whose own bodyless case had the same shape.

The two remaining bare reads are left alone: neither declares what a
missing body should do, so there is no stated intent to honour.

31 install tests plus 17 body tests. The install pair is checked against
each other rather than only individually — the same install logic is
written twice, once in the queue callback and once in the fallback, so
the tests assert both produce identical schema, discovery, state and
history effects. They agree today; the one difference is the success
message wording, which is characterized rather than changed.

* test(api): cover the raw config write endpoints

/config/raw/main and /config/raw/secrets write whatever JSON they are
given straight to config.json and config_secrets.json, bypassing the
secret-separation path the rest of the config surface goes through. Given
how carefully that surface keeps secrets out of config.json, the pair
that skips it was worth pinning precisely. Backed by a real
ConfigManager over tmp_path, so the assertions are against files on disk.

20 tests covering both routes: what lands in which file, that a raw
secrets write never touches config.json and vice versa, the GitHub token
reload, the uninitialized-manager and empty-body branches, and the
ConfigError path that carries config_path through to the response.

The bypass itself is pinned as intentional rather than changed — these
back the raw JSON editor, so writing the body verbatim is the feature.
The test says so explicitly, because the failure mode is someone later
routing plugin config through here as a convenience and silently losing
secret separation.

* test(api): cover backup restore and path containment, and fix restore scope

Restore is the most destructive thing the web interface can do — it
overwrites config, secrets, WiFi settings and fonts, then reinstalls
plugins — and neither it nor the file routes beside it had tests.

A malformed `options` field fell back to {}. Every RestoreOptions flag
defaults to True, so a caller who asked for a narrow restore and
mis-serialized the request got a full one instead, secrets included, and
was told it succeeded. Valid JSON that is not an object was worse:
`"null"` or `"[1,2]"` reached .get() on a non-dict and raised, so the
request died as a generic 500. Both are now refused with a 400 that says
what was wrong, and restore_backup is never reached.

The other file routes take a filename straight out of the URL and turn it
into a path — one to read, one to unlink. _safe_backup_path is the only
thing keeping those inside the export directory, and it was untested. No
bypass was found; the thirteen traversal shapes are pinned so a later
loosening of that pattern has to argue with something. The delete route's
by-name enumeration is covered too, including that a directory sharing a
backup's name is not removed.

84 tests. Two behaviours are pinned as intentional: a failed plugin
reinstall turns the whole restore into an error even though file
restoration succeeded, and omitting `options` entirely still means
restore everything — that is the documented default, and it is only the
mis-serialized case that was wrong.

* test(sync): probe for a free port on loopback, not every interface

CodeQL flagged the ephemeral-port probe in the handshake test for
binding to all interfaces. The probe only needs a free port number, so
loopback is both sufficient and correct — a test should not open a port
to the network to discover one.

The manager under test still binds to all interfaces, which is
deliberate and already marked nosec: a follower has to receive the
leader's UDP broadcast.

* fix: bound the logo download, and stop malformed input reading as a fault

Review findings on the coverage branch.

The download size cap I added checked len(response.content), which has
already buffered the whole body -- it stopped the bytes reaching disk but
not memory, which was the point. A server that omits Content-Length and
never stops sending would still exhaust the process. Stream it instead,
counting as it arrives, into a sibling .part file that is replaced over
the target only once it decodes. A transfer that dies midway now leaves
nothing behind rather than a truncated logo for load_logo() to cache.

The follower's control-message handler caught three exception types, but
two reachable UDP payloads raise others: a bare JSON scalar makes
msg.get() raise AttributeError, and an "sx" carrying a non-numeric x
raises ValueError or TypeError from float(). Those escaped to the outer
handler, skipping the legacy-PNG fallback and -- since this branch added
a backoff there -- charging one malformed packet a 0.1s stall on the
receive path. The legacy-PNG path also decoded without the dimension cap
its TCP counterpart applies, so a crafted 65KB frame could force a large
allocation on the render thread; both paths now share one constant.

Three repo_url handlers called .strip() on client input without checking
it was a string, so {"repo_url": 12345} answered 500. The credentials
upload parsed the same file twice, the second time inside a bare except
that a preceding parse had already made unreachable. And both raw-config
handlers kept a json.JSONDecodeError arm that get_json(silent=True) had
turned into dead code, collapsing "sent something unparseable" into "sent
nothing" -- they now say which.

Two of the new tests were not testing what they claimed. The pruning
round-trip wrote ten backups inside one second, so all ten landed on the
same int(time.time()) filename and overwrote each other; it never reached
the limit it asserted. And the sync clock helper patched attributes on the
stdlib time module, freezing time process-wide for every daemon thread
earlier tests had left running.

Full suite: 3352 passed, coverage 54%.

* test(sync): probe broadcast by sending, not by listening

The broadcast check added in the previous commit bound INADDR_ANY to
receive its own probe datagram, and the free-port probe did the same to
pick a port. CodeQL flagged both, correctly: a test suite has no reason
to open a socket the whole network can reach.

Sending is enough for what the probe is actually for. An environment
that refuses broadcast raises on sendto, which is the case that occurs
in sandboxes and is the one worth skipping over; confirming delivery
would have required the listening socket. A network that accepts the
send and silently drops it still reaches the assertion, exactly as it
did before either commit. The port probe binds loopback -- it only needs
a number, and the manager's own bind is the one that has to succeed, with
the retry loop already covering a port taken elsewhere.

* fix: keep callback faults out of the frame-decode fallback

Review follow-up on the previous two commits.

Widening the control-message except tuple put the callback dispatch
inside it, so an _on_new_cycle() that raised ValueError, TypeError or
AttributeError sent a perfectly good control packet to the legacy PNG
decoder -- which reported it as an image decode error and buried the
real fault. Split the two: whether the payload parses as JSON decides
frame vs control message, a second guard covers reading the fields of an
attacker-shaped body, and the callback fires outside both. It still
cannot kill the receive thread; the loop's own handler catches it, and
now says what actually went wrong.

The logo download's temp file was a fixed "<name>.part". Two plugins
asking for the same logo at once would interleave writes into it,
publish the mixture, or delete each other's partial. mkstemp gives each
download its own name in the same directory, so os.replace stays atomic.
Its descriptor is adopted by fdopen before the request runs, since a
request that raises before the write would otherwise leak the fd --
quietly, because load_logo_with_download swallows that.

Two test fixes: the oversized-frame test replaced PIL.Image.open
process-wide, the same hazard the clock helper documents, and Ruff B007
on an unused loop variable.

Full suite: 3355 passed, coverage 54%.

* test(sync): cover the announce loop, and reject non-finite scroll positions

Three review findings from the follower receive path.

Non-finite scroll x reached follower rendering. json.loads accepts the
bare NaN/Infinity literals and float() accepts them as strings, so
"x": NaN arrived as a real float and was stored verbatim. NaN loses
every comparison the scroll code makes, so a follower given one sits on
a position it can never advance past. It now raises through the existing
malformed-control-message guard, which logs and drops the packet and
leaves the last good position in place.

_broadcast_available() only proves the host accepts sendto() for a
broadcast; a network that accepts the send and drops the packet would
let TestRealSocketHandshake run to its five-second deadline and fail on
assertions the code did not break. The deadline now distinguishes the
two: if not one packet crossed in either direction, that is the
environment, and the test skips rather than reporting a protocol
failure.

That skip could hide a real regression in the announcing side, so
TestFollowerAnnounceLoop covers it on mock sockets, where no network is
involved and nothing can skip: hello carries this display's hardware
config and goes to the broadcast address, heartbeats follow, an empty
hardware config falls back to 32x64x1, hello is not resent before its
interval, and a send failure is swallowed rather than killing the loop.

The partial dispatcher still routed 'weather' and 'stocks' to loaders
rendering v3/partials/weather.html and stocks.html — templates that no

either partial raised TemplateNotFound, which the catch-all turned into
a 500. No template or JS references these partials (the only 'weather'

development_mode, which the web UI reads and writes but the template

  monorepo), so it cannot ever have run; its README section claimed
  scripts/dev/* used it, which was also untrue.
- src/web_interface/logging_config.py: zero callers — the web app uses
  web_interface/logging_config.py (a different module), and nothing
  imports the src copy.
- handle_errors decorator in src/web_interface/error_handler.py: zero
  call sites (the module's response helpers stay — they are used).
- ConfigManager.get_clock_config(): reads a 'clock' config key that no
  longer exists anywhere; only caller was its own unit test.

Deliberately kept despite zero in-repo callers: DisplayError,
src/common/config_helper.py and display_helper.py — all documented as
plugin-facing API (docs/PLUGIN_ERROR_HANDLING.md, src/common/README.md),
and third-party plugins outside the official monorepo cannot be

plugins — inside try/except blocks that swallowed the ImportError, so
they passed while exercising nothing. test_nba_data_structure.py and
debug_nba_api.py (a diagnostic script living in test/) made live ESPN
API calls rather than testing repo code. None were enrolled in CI.

scripts/debug/direct_fix_imports.py and check_imports.py were one-shot
artifacts that edited/inspected a hardcoded ~/LEDMatrix/web_interface/
app.py to fix an import problem solved long ago; nothing references
them.

* chore: remove generate_report.py, which aggregates artifacts of CI jobs that do not exist

The script's only function is to merge JSON artifacts
(bandit/semgrep/pip-audit/safety/gitleaks results) produced by a
security-audit workflow that was never committed —
.github/workflows/ has no such jobs, so there is nothing for it to
aggregate and no way to run it usefully. Its siblings stay:
prove_security.py and audit_plugins.py both run standalone (verified),
and .codacy.yml stays because the Codacy service (README badge) reads it
server-side without a workflow file.

* fix(web): load the three widget scripts store plugins already declare

time-picker.js, file-upload-single.js and plugin-file-manager.js
register widgets that installed store plugins reference in their config
schemas (countdown uses x-widget: time-picker and file-upload-single;
of-the-day uses plugin-file-manager), but base.html never included the
scripts. plugin_config.html renders such fields as an empty container
that polls LEDMatrixWidgets.get(...) on a 50ms loop forever, so those
plugin config fields appeared permanently blank. The audit initially
flagged these files as dead code; the monorepo cross-check proved the
opposite — they were unreachable, not unused.

example-color-picker.js (the documented custom-widget example) gains an
explicit warning that including it in base.html would shadow the
built-in color-picker widget.

* chore: drop the legacy youtube block from the secrets template

No code reads a top-level youtube secrets key: the youtube-stats plugin
receives its API key namespaced under its own plugin id (declared via
x-secret in its config schema), like every other store plugin. The key
survives only in state_reconciliation.py's non-plugin-key exclusion set,
which stays — existing installs still carry the key in their generated
config_secrets.json, and the exclusion prevents it from being
misclassified as a plugin config. New installs simply stop being asked
for a YouTube API key they have nowhere to use.

* chore(deps): remove packages nothing imports, declare direct imports, move mypy to test deps

Removed from requirements.txt: python-socketio, python-engineio,
websockets, websocket-client — zero imports anywhere in this repo, and
the one store plugin that needs Socket.IO (ledmatrix-music) declares it
in its own requirements.txt, which the plugin store installs. Removed
the same quartet plus timezonefinder, geopy, google-auth-oauthlib,
google-auth-httplib2, google-api-python-client, unidecode, icalevents,
python-dateutil, flask-wtf and the werkzeug pin from
web_interface/requirements.txt — all leftovers from the deleted built-in
weather/calendar/music displays (flask-wtf was doubly dead: app.py
explicitly disables CSRF and sets csrf=None). scripts/
install_dependencies_apt.py, which mirrors these lists for the
first-time installer, drops the same packages.

Added: urllib3 (imported directly in four core modules), jinja2 and
markupsafe (imported directly in pages_v3.py) — previously reachable
only as transitives. mypy moves from runtime requirements to
requirements-test.txt.

Verified in a fresh venv: all four requirements files co-install, pip
check is clean, the full CI-enrolled suite (907 tests) and a Flask boot
smoke pass with the trimmed dependency set.

* refactor: single canonical DateTimeEncoder

src/cache_manager.py and src/cache/disk_cache.py each defined an
identical DateTimeEncoder (datetime -> ISO-8601). The disk_cache copy is
the only one actually used for serialization; cache_manager now
re-exports it instead of defining a twin, so the two can never silently
diverge. Import compatibility is preserved — from src.cache_manager
import DateTimeEncoder still works and is the same class object.

* docs(code): document deliberate duplicates instead of merging them

The audit surfaced several near-duplicate implementations that turned
out to be either deliberate forks or behaviorally different — merging
any of them would risk changing behavior on installed devices, so each
now carries an explicit comment stating the relationship:

- VisualDisplayManager: headless fork of DisplayManager; header now
  lists the ~15 mirrored methods and warns that DisplayManager changes
  must be mirrored.
- normalize_abbreviation: LogoDownloader's version (called directly by
  nine scoreboard plugins) replaces filesystem-unsafe characters;
  LogoHelper's strips spaces. Logo filenames on existing installs
  depend on both behaviors staying put.
- The two PluginTestBase classes: the shipped one is plugin-author
  API, the repo's own richer harness lives in test/plugins/ — now
  cross-referenced.

Also verified (no change needed): ConfigManager's backup/rollback
methods genuinely delegate to AtomicConfigManager, and SportsCore
already delegates _read_bdf_native_size to FontManager.

* docs: add a unified configuration reference

There was no single place documenting what lives in config.json —
display.* keys were scattered across README sections, vegas_scroll lived
in ADVANCED_FEATURES.md, and dim_schedule, display.double_sided,
sync.follower_position, plugin_system.development_mode and the four
newly-templated hardware keys were documented nowhere. CONFIG_REFERENCE.md
now lists every template key plus the code-read-only keys, each with
type, default, and the code location that reads it, and explains the
secrets file's plugin-id namespacing. Linked from the docs index.

* docs: bring the README's feature tour into the plugin era

The Core Features section still presented clock/weather/sports/stocks/
music displays as built into the project, when all of them are store
plugins installed from the ledmatrix-plugins monorepo — only
starlark-apps and web-ui-info ship in this repo. The intro now says so
(the showcase itself is unchanged; those are real displays available in
the store). The display_durations reference drops its built-in-calendar
example in favor of plugin-id keys, and the Configuration section links
the new CONFIG_REFERENCE.md.

* docs: archive the custom-icons status report, cross-link config docs, document assets/

PLUGIN_CUSTOM_ICONS_FEATURE.md was a 'What Was Implemented' status
report duplicating the actual guide (PLUGIN_CUSTOM_ICONS.md) — moved to
docs/archive/ per the docs index's own policy. The overlapping
plugin-config docs keep their content but PLUGIN_CONFIG_ARCHITECTURE.md
now states up front which doc is canonical for which purpose.

assets/README.md is new and load-bearing: assets/stocks, weather,
news_logos and broadcast_logos have zero references in this repo's code,
which makes them look deletable — but store plugins (ledmatrix-stocks,
ledmatrix-weather, news, odds-ticker) resolve those exact paths at
runtime against the install directory. The README records that evidence
so a future cleanup doesn't break installed plugins.

* test: add regression guards for the bug classes fixed in this PR

Three lightweight static checks, all enrolled in CI's unit-test
allowlist along with the new web-cache test:

- test_template_targets.py: every literal render_template() target must
  exist (would have caught the weather/stocks partial 500s at commit
  time).
- test_widget_scripts.py: every widget JS file must be script-included
  in base.html or explicitly allowlisted with a reason (would have
  caught the unloaded time-picker/file-upload-single/plugin-file-manager
  widgets), and allowlisted files must NOT be included (prevents the
  example widget from shadowing the real color-picker).
- test_doc_links.py: relative markdown links in active docs must
  resolve (docs/archive/ exempt).

Each guard was verified to fail against the pre-PR tree and pass now.

* fix(deps): restore the werkzeug version floor

Commit 1ec22db removed the werkzeug>=3.1.6,<4.0.0 pin along with the
genuinely-unused packages, but this one was a version floor on Flask's
transitive dependency, not a phantom: Flask 3.1.3 itself only requires
werkzeug>=3.1.0, so dropping the pin let fresh installs resolve
3.1.0-3.1.5. Restored with a comment explaining why it exists.

* fix(web): route pixel_mapper_config into display.hardware; guard time-picker registration

pixel_mapper_config was the only display.hardware key absent from both
the display_fields detection allowlist and the hardware write loop in
the settings save path. No form posts it today, but if one ever did the
key would fall through to the generic handler and land at the TOP level
of config.json — where state_reconciliation would mistake it for a
missing plugin id and loop auto-repair attempts (the failure class the
'github'/'youtube' exclusion comment documents). It now round-trips
into display.hardware like its siblings.

time-picker.js gains the same LEDMatrixWidgets-undefined guard its two
sibling widgets already have; correct today only via defer ordering.

* chore: align installer leftovers with the dependency cleanup

first_time_install.sh's fallback secrets heredoc (used only when the
template is missing) still wrote the legacy youtube block — now matches
the template (github only). install_dependencies_apt.py drops the
IMPORT_NAME_MAP entries for packages no longer in its install lists and
a stale google-api reference in a docstring.

* fix: address CodeRabbit review findings

Verified each finding against the code; fixes for the valid ones:

- install_dependencies_apt.py: the installer listed 'freetype', but the
  declared dependency is freetype-py — an apt miss would pip-install the
  wrong PyPI package. Now installs freetype-py with an import-name
  mapping (pre-existing bug, surfaced by the review).
- api_v3.py: pixel_mapper_config is validated as a string before being
  saved to display.hardware (JSON callers could previously store an
  object/list the matrix library can't use).
- .cursorrules: the Plugin Loading Process and File Organization
  sections still said discovery scans plugins/ — now consistent with the
  corrected overview (configured directory, default plugin-repos/).
- README.md: removed the stale '(except the core calendar)' claim — no
  core calendar exists in src/ — and qualified the plugin inventory
  (official plugins in the monorepo; third-party from their own repos).
- CONFIG_REFERENCE.md: hardware_mapping now shows the code fallback
  (adafruit-hat-pwm) alongside the template value.
- PLUGIN_REGISTRY_SETUP_GUIDE.md: check_plugin.py takes --plugin, not a
  positional id.
- scripts/fix_perms/fix_*.sh: exec bits set so the documented
  'sudo ./...' invocations work.
- Guard tests hardened: template guard now catches multi-line
  render_template() calls; widget guard parses actual <script> src
  values and fails if the widgets dir goes missing; type hints and
  docstrings added per repo coding guidelines.

Skipped with reasons (noted on the PR): limit_refresh_rate_hz 100-vs-90
is documented as intentional in CONFIG_REFERENCE.md; the psutil comment
already names the enforcing manifest; docs/archive/ findings are out of
scope per the docs policy (archive may rot).

* chore: remove Cursor IDE tooling, consolidate its guidance into CLAUDE.md

The maintainer no longer uses Cursor. .cursorrules, .cursorignore and the
.cursor/ tree (rules, plugin templates, a parallel 751-line plugins
guide) are removed; measurement showed near-zero literal overlap risk —
the canonical content already lives in docs/. Unique guidance worth
keeping moved before deletion:

- CLAUDE.md gains the dev workflow (dev_plugin_setup.sh, dev_server.py,
  run.py -e, check_plugin.py), the plugin-secrets namespacing contract,
  and the no-draw_image()/paste-onto-PIL pitfall.
- PLUGIN_DEVELOPMENT_GUIDE.md absorbs the plugin version-management
  rules (pre-push hook install, SKIP_TAG, version resolution order) that
  its own text previously linked out to .cursorrules for.
- The one completed plan doc (.cursor/plans/) is archived to
  docs/archive/ per the docs policy rather than deleted.

One of the deleted rule files (sports-managers.mdc) targeted
src/*_managers.py globs that have matched nothing since the plugin
migration.

* chore: second-pass cleanup — dead installer branch, broken script, orphaned JS, misfiled test deps

- first_time_install.sh: removed the pip fallback branch that installed
  from requirements_web_v2.txt — a file that has not existed since the
  v2 web interface was removed (the branch always printed its own
  'not found; skipping' warning).
- scripts/remove_plugin_backups.sh deleted: its PROJECT_ROOT resolved to
  the repo's PARENT directory, and its verify_submodules() checks for
  plugin submodules from an era before plugins moved to the store — it
  could never have worked from its current location.
- plugins_manager.js: removed three functions with zero call sites
  anywhere (addKeyValuePair, formatCommit, togglePasswordVisibility) —
  verified against all templates, all JS, and the dynamic window[name]
  dispatch sites, which resolve widget-registry keys only. Also replaced
  base.html's misleading 'Legacy ... during migration' label: the file
  is deliberately loaded last and provides the LIVE implementations of
  seven window.* plugin actions that shadow same-named definitions in
  app.js/app-shell.js.
- pytest/pytest-cov/pytest-mock moved from runtime requirements.txt to
  requirements-test.txt (CI already installs both files; the installer's
  line-by-line loop simply installs three fewer packages on devices; no
  store plugin declares pytest). HOW_TO_RUN_TESTS.md updated.
- scripts/add_defaults_to_schemas.py and analyze_plugin_schemas.py
  scanned the empty legacy plugins/ dir — now scan plugin-repos/.

Verified: fresh venv installs all four requirements files with pip check
clean and pytest available; bash -n on the installer; node --check on
the JS; widget/cache guard tests green.

* docs: correct semantically stale content across the user and developer guides

A second-pass content audit checked the guides' substantive claims
against the code (the first pass only fixed mechanical drift). Fixes:

- GETTING_STARTED: described booting a prebuilt SD image and seeing
  default clock/weather plugins — neither exists. Now documents the real
  install (Pi OS Lite + one-shot installer / first_time_install.sh) and
  that displays come from the Plugin Store. Duration and ordering
  instructions moved to the Rotation tab where the controls actually
  live.
- WEB_INTERFACE_GUIDE: three whole tabs were undocumented (Rotation,
  Backup & Restore, Tools) and the Display tab's Vegas Scroll section
  was unmentioned. Fonts overrides are per display element (not per
  plugin); Logs has an Auto-scroll checkbox (not a Pause button); the
  aspirational keyboard-shortcut list and no-JS claim removed.
- TROUBLESHOOTING: the hand-written service-file template (wrong user,
  wrong ExecStart, dropped the autostart gate) replaced with the real
  systemd/ units + install scripts; recovery steps no longer copy
  placeholder units verbatim; WiFi curl endpoint corrected to /api/v3/;
  cache-clearing advice now targets the real cache locations.
- ADVANCED_FEATURES: removed a false claim that CacheManager has no
  delete(); fixed two example snippets that raise TypeError
  (BackgroundDataService and get_config_file_mode signatures); fixed
  cache paths, a 5-minute TTL that is actually 1 hour, and the vegas
  table now links the complete 26-key reference.
- EMULATOR_SETUP_GUIDE: documented run.py flags that don't exist
  (--plugin/--test-plugins) removed in favor of dev_server.py and
  check_plugin.py; shipped emulator config values corrected (browser
  adapter default on :8888, not pygame).
- PLUGIN_QUICK_REFERENCE: drag-and-drop reordering is shipped, not
  'not yet supported'; discovery-fallback and registry-repo claims
  corrected. PLUGIN_API_REFERENCE: get_vegas_segment_width returns
  panels, not pixels. CONTRIBUTING: the repo uses flake8/mypy/bandit
  pre-commit hooks, not black/ruff, and tests need requirements-test.txt.
- SKIN_SYSTEM/DEVELOPER_QUICK_REFERENCE: stale module paths.

* fix: raise the two new dependency floors past their CVEs, silence a deliberate re-export

All three of these were introduced by this PR, which is what makes them
worth fixing here rather than deferring.

`urllib3` and `jinja2` were added to the requirements so that direct
imports stop relying on transitives — right call, but both floors were
set to the version that introduced the API rather than a version that is
safe to install. `urllib3>=1.26.0` sits below roughly ten CVEs including
a decompression-bomb safeguard bypass, and `jinja2>=3.1.0` below five
including two sandbox breakouts. Raised to 2.7.0 and 3.1.6, which is what
a working device already runs, so no install is disturbed. The comments
now say the floor is a security floor, since the next person to read
"imported directly" would otherwise reasonably lower it again.

This is the same reasoning the PR already applied to werkzeug; these two
just missed it.

The `DateTimeEncoder` import in cache_manager is unused on purpose — the
canonical class moved to src.cache.disk_cache and this re-export keeps
the documented import path working. flake8 cannot see intent, so it gets
an explicit `# noqa: F401` rather than being removed and quietly breaking
anything importing it from here. Verified the re-export still resolves to
the same object and still serialises datetimes.

* fix: address CodeRabbit re-review — installer robustness and doc lint

- install_dependencies_apt.py: an import-only check let Debian
  Bookworm's python3-freetype 2.3.0 satisfy the freetype-py>=2.5.1 pin.
  check_package_installed() now verifies the installed freetype-py
  version, and an apt install that lands below the minimum falls through
  to pip instead of counting as success.
- first_time_install.sh: the .web_deps_installed marker was created even
  when the smart installer failed, so re-runs skipped installation with
  dependencies missing. The marker is now created only on success.
- CONTRIBUTING.md: document installing the pre-commit CLI before
  'pre-commit install' (the requirements files don't provide it).
- Doc lint: fence language on the on-demand cache example (MD040),
  blockquote continuation in GETTING_STARTED (MD028), and the
  suppress_adapter_load_errors key removed from the emulator debug
  example to match the options table.

Skipped one finding with reason (noted on the PR): the per-plugin
display_duration field in PLUGIN_QUICK_REFERENCE's example is not
obsolete — BasePlugin.get_display_duration() reads it and
PLUGIN_CONFIG_CORE_PROPERTIES.md documents it as a core property;
display.display_durations is a per-mode override, not a replacement.

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.

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

* 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.

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

* 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.

* 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.

* docs: document scoreboard_regions' center-reserve and score-bleed params

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

* fix: address CodeRabbit review on PR #393

- docs: scope the self.layout note to BasePlugin subclasses (others build
  a LayoutContext directly) and make explicit that adaptive layout is
  opt-in — classic rendering stays unless a plugin adopts the APIs.
- 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.

* fix(dev-server): allowlist plugin_id before any path lookup

CodeQL (py/path-injection): plugin_id arrives in request input and flows
into filesystem paths via find_plugin_dir. Gate it with the same
^[a-zA-Z0-9_-]{1,64}$ allowlist the web UI's pages_v3 uses, at the
single choke point every route resolves through.

* fix(dev-server): lexical containment check on resolved plugin dirs

CodeQL doesn't recognize the interprocedural allowlist as a
path-injection barrier; add the canonical one — normalize (without
following symlinks, since dev plugins are commonly symlinked into
plugins/) and require the result to stay inside the search dir.

* fix(dev-server): inline normpath containment barrier before render

CodeQL doesn't credit the sanitization inside find_plugin_dir along
this flow; apply its documented barrier (normpath + startswith against
the allowed roots) inline in _parse_render_request, on the exact path
that reaches the render/load sinks.

* fix(dev-server): derive plugin dir from trusted directory listings

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.

* 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)

* 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.

* chore(dev): add Pillow compatibility smoke test script

Covers all Pillow APIs used in LEDMatrix — image creation, drawing,
font metrics, LANCZOS resampling, paste/alpha_composite, and PNG I/O.
Run after any Pillow version bump to catch regressions before deploy.

    python3 scripts/dev/test_pillow_compat.py

* 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

Also fixed permission issue on devpi:
- Changed /var/cache/ledmatrix/display_on_demand_state.json permissions
  from 600 to 660 to allow web service (devpi user) to read the file

* fix(cache): Ensure cache files use 660 permissions for group access

- Updated setup_cache.sh to set file permissions to 660 (not 775)
- Updated first_time_install.sh to properly set cache file permissions
- Modified DiskCache to set 660 permissions when creating cache files
- Ensures display_on_demand_state.json and other cache files are readable
  by web service (devpi user) which is in ledmatrix group

This fixes permission issues where cache files were created with 600
permissions, preventing the web service from reading them. Now files
are created with 660 (rw-rw----) allowing group read access.

* fix(soccer-scoreboard): Update submodule with manifest fix

- Updated soccer-scoreboard plugin submodule
- Added missing entry_point and class_name to manifest.json
- Fixes plugin loading error: 'No class_name in manifest'

Also fixed cache file permissions on devpi server:
- Changed display_on_demand_state.json from 600 to 660 permissions
- Allows web service (devpi user) to read cache files

* fix(display): Remove update_display() calls from clear() to prevent black flash

Previously, display_manager.clear() was calling update_display() twice,
which immediately showed a black screen on the hardware before new
content could be drawn. This caused visible black flashes when switching
between modes, especially when plugins switch from general modes (e.g.,
football_upcoming) to specific sub-modes (e.g., nfl_upcoming).

Now clear() only prepares the buffer without updating the hardware.
Callers can decide when to update the display, allowing smooth transitions
from clear → draw → update_display() without intermediate black flashes.

Places that intentionally show a cleared screen (error cases) already
explicitly call update_display() after clear(), so backward compatibility
is maintained.

* fix(scroll): Prevent wrap-around before cycle completion in dynamic duration

- Check scroll completion BEFORE allowing wrap-around
- Clamp scroll_position when complete to prevent visual loop
- Only wrap-around if cycle is not complete yet
- Fixes issue where stocks plugin showed first stock again at end
- Completion logged only once to avoid spam
- Ensures smooth transition to next mode without visual repeat

* fix(on-demand): Ensure on-demand buttons work and display service runs correctly

- Add early stub functions for on-demand modal to ensure availability when Alpine.js initializes
- Increase on-demand request cache max_age from 5min to 1hr to prevent premature expiration

- Ensure form-groups are in normal document flow with float: none

* fix: Use JavaScript to toggle overflow instead of :has() selector

- :has() selector may not be supported in all browsers
- Use JavaScript to set overflow: visible when expanded, hidden when collapsed
- This ensures better browser compatibility while maintaining functionality

* fix: Make parent sections expand when nested sections expand

- Add updateParentNestedContentHeight() helper to recursively update parent heights
- When a nested section expands, recalculate all parent nested-content max-heights
- Ensures parent sections (like NFL) expand to accommodate expanded child sections
- Updates parent heights both on expand and collapse for proper animation

* refactor: Simplify parent section expansion using CSS max-height: none

- Remove complex recursive parent height update function
- Use CSS max-height: none when expanded to allow natural expansion
- Parent sections automatically expand because nested-content has no height constraint
- Simpler and more maintainable solution

- Track enabled state preservation during config save
- Track state reconciliation fixes
- Track enabled state updates in on_config_change

This will help identify which code path is causing plugins to disable.

* debug: Fix debug log path to work on Pi

Changed hardcoded log path to use dynamic project root detection:
- Uses LEDMATRIX_ROOT env var if set
- Falls back to detecting project root by looking for config directory
- Creates .cursor directory if it doesn't exist
- Falls back to /tmp/ledmatrix_debug.log if all else fails
- Added better error handling with logger fallback

- When enabled, moves fixed pixels per step, throttled by scroll_delay
- Eliminates time-based jitter by ignoring frame timing variations
- Provides stock-ticker-like smooth, predictable scrolling
- Update text-display plugin to use frame-based mode

This addresses stuttering issues where time-based scrolling caused
visual jitter due to frame timing variations in the main display loop.

* fix(scroll): Fix NumPy broadcasting errors in sub-pixel wrap-around

- Ensure _interpolate_subpixel always returns exactly requested width
- Handle cases where scipy.ndimage.shift produces smaller arrays
- Add padding logic for wrap-around cases when arrays are smaller than expected

- Restore time-based throttling using scroll_delay
- Move pixels only when scroll_delay has passed
- Handle lag catch-up with reasonable caps to prevent huge jumps
- Preserve fractional timing for smooth operation
- Now scroll_delay actually controls the scroll speed as intended

* feat(text-display): Add FPS counter logging

- Update submodule reference
- Adds FPS tracking and logging every 5 seconds

* fix(text-display): Add display-width buffer so text scrolls completely off

- Update submodule reference
- Adds end buffer to ensure text exits viewport before looping

* fix: Prevent premature game switching in SportsLive

- Set last_game_switch when games load even if current_game already exists
- Set last_game_switch when same games update but it's still 0
- Add guard to prevent switching check when last_game_switch is 0
- Fixes issue where first game shows for only ~2 seconds before switching
- Also fixes random screen flickering when games change prematurely

- Add branch input to custom registry plugin cards
- Each plugin can now have its own branch specified independently

* debug: Add logging to _should_exit_dynamic

* feat(display_controller): Add universal get_cycle_duration support for all plugins

UNIVERSAL FEATURE: Any plugin can now implement get_cycle_duration() to dynamically
calculate the total time needed to show all content for a mode.

New method:
- _plugin_cycle_duration(plugin, display_mode): Queries plugin for calculated duration

Integration:
- Display controller calls plugin.get_cycle_duration(display_mode)
- Uses returned duration as target (respecting max cap)
- Falls back to cap if not provided

Benefits:
- Football plugin: Show all games (3 games × 15s = 45s total)
- Basketball plugin: Could implement same logic
- Hockey/Baseball/any sport: Universal support
- Stock ticker: Could calculate based on number of stocks
- Weather: Could calculate based on forecast days

Example plugin implementation:

Result: Plugins control their own display duration based on actual content,
creating a smooth user experience where all content is shown before switching.

* debug: Add logging to cycle duration call

* debug: Change loop exit logs to INFO level

* fix: Change cycle duration logs to INFO level

* fix: Don't exit loop on False for dynamic duration plugins

For plugins with dynamic duration enabled, keep the display loop running
even when display() returns False. This allows games to continue rotating
within the calculated duration.

The loop will only exit when:
- Cycle is complete (plugin reports all content shown)
- Max duration is reached
- Mode is changed externally

* fix(schedule): Improve display scheduling functionality

- Add GET endpoint for schedule configuration retrieval
- Fix mode switching to clean up old config keys (days/start_time/end_time)
- Improve error handling with consistent error_response() usage
- Enhance display controller schedule checking with better edge case handling
- Add validation for time formats and ensure at least one day enabled in per-day mode
- Add debug logging for schedule state changes

Fixes issues where schedule mode switching left stale config causing incorrect behavior.

* fix(install): Add cmake and ninja-build to system dependencies

Resolves h3 package build failure during first-time installation.
The h3 package (dependency of timezonefinder) requires CMake and
Ninja to build from source. Adding these build tools ensures
successful installation of all Python dependencies.

* fix: Pass display_mode in ALL loop calls to maintain sticky manager

CRITICAL FIX: Display controller was only passing display_mode on first call,
causing plugins to fall back to internal mode cycling and bypass sticky
manager logic.

Now consistently passes display_mode=active_mode on every display() call in
both high-FPS and normal loops. This ensures plugins maintain mode context
and sticky manager state throughout the entire display duration.

* feat(install): Add OS check for Raspberry Pi OS Lite (Trixie)

- Verify OS is Raspberry Pi OS (raspbian/debian)
- Require Debian 13 (Trixie) specifically
- Check for Lite version (no desktop environment)
- Exit with clear error message if requirements not met
- Provide instructions for obtaining correct OS version

* fix(web-ui): Add missing notification handlers to quick action buttons

- Added hx-on:htmx:after-request handlers to all quick action buttons in overview.html
- Added hx-ext='json-enc' for proper JSON encoding
- Added missing notification handler for reboot button in index.html
- Users will now see toast notifications when actions complete or fail

* fix(display): Ensure consistent display mode handling in all plugin calls

- Updated display controller to consistently pass display_mode in all plugin display() calls.
- This change maintains the sticky manager state and ensures plugins retain their mode context throughout the display duration.
- Addresses issues with mode cycling and improves overall display reliability.

* fix(display): Enhance display mode persistence across plugin updates

- Updated display controller to ensure display_mode is consistently maintained during plugin updates.
- This change prevents unintended mode resets and improves the reliability of display transitions.
- Addresses issues with mode persistence, ensuring a smoother user experience across all plugins.

* feat: Add Olympics countdown plugin as submodule

- Add olympics-countdown plugin submodule
- Update .gitignore to allow olympics-countdown plugin
- Plugin automatically determines next Olympics and counts down to opening/closing ceremonies

* feat(web-ui): Add checkbox-group widget support for multi-select arrays

- Add checkbox-group widget rendering in plugins_manager.js
- Update form processing to handle checkbox groups with [] naming
- Support for friendly labels via x-options in config schemas
- Update odds-ticker submodule with checkbox-group implementation

* fix(plugins): Preserve enabled state when saving plugin config from main config endpoint

When saving plugin configuration through save_main_config endpoint, the enabled
field was not preserved if missing from the form data. This caused plugins to
be automatically disabled when users saved their configuration from the plugin
manager tab.

This fix adds the same enabled state preservation logic that exists in
save_plugin_config endpoint, ensuring consistent behavior across both endpoints.
The enabled state is preserved from current config, plugin instance, or defaults
to True to prevent unexpected disabling of plugins.

* fix(git): Resolve git status timeout and exclude plugins from base project updates

- Add --untracked-files=no flag to git status for faster execution
- Increase timeout from 5s to 30s for git status operations
- Add timeout exception handling for git status and stash operations

* fix(scroll): Correct dynamic duration calculation for frame-based scrolling

- Fix calculate_dynamic_duration() to properly handle frame-based scrolling mode
- Convert scroll_speed from pixels/frame to pixels/second when in frame-based mode
- Prevents incorrect duration calculations (e.g., 2609s instead of 52s)
- Affects all plugins using ScrollHelper: odds-ticker, leaderboard, stocks, text-display
- Add debug logging to show scroll mode and effective speed

* Remove version logic from plugin system, use git commits instead

- Remove version parameter from install_plugin() method
- Rename fetch_latest_versions to fetch_commit_info throughout codebase

- Remove version logging from plugin manager
- Update web UI to use fetch_commit_info parameter
- Update .gitignore to ignore all plugin folders (remove whitelist exceptions)
- Remove plugin directories from git index (plugins now installed via plugin store only)

Plugins now always install latest commit from default branch. Version fields
replaced with git commit SHA and commit dates. System uses git-based approach
for all plugin metadata.

* feat(plugins): Normalize all plugins as git submodules

- Convert all 18 plugins to git submodules for uniform management
- Add submodules for: baseball-scoreboard, christmas-countdown, football-scoreboard, hockey-scoreboard, ledmatrix-flights, ledmatrix-leaderboard, ledmatrix-music, ledmatrix-stocks, ledmatrix-weather, static-image
- Re-initialize mqtt-notifications as proper submodule
- Update .gitignore to allow all plugin submodules
- Add normalize_plugin_submodules.sh script for future plugin management

All plugins with GitHub repositories are now managed as git submodules,

All scripts now correctly determine project root after reorganization.

* fix(install): Update first_time_install.sh to detect and update service files with old paths

- Check for old paths in service files and reinstall if needed
- Always reinstall main service (install_service.sh is idempotent)
- This ensures existing installations get updated paths after reorganization

* fix(install): Update install_service.sh message to indicate it updates existing services

* fix(wifi): Enable WiFi scan to work when AP mode is active

- Replace Alpine.js x-for template with manual DOM manipulation
- Add updateSelectOptions() method to directly update select dropdown
- This fixes issue where networks weren't appearing in dropdown
- Alpine.js x-for inside select elements can be unreliable

* feat(web-ui): Add patternProperties support for dynamic key-value pairs

- Add UI support for patternProperties objects (custom_feeds, feed_logo_map)
- Implement key-value pair editor with add/remove functionality
- Add JavaScript functions for managing dynamic key-value pairs

- Enable easy configuration of feed_logo_map in web UI

* chore: Update ledmatrix-news submodule to latest commit

* fix(plugins): Handle arrays of objects in config normalization

Fix configuration validation failure for static-image plugin by adding
recursive normalization support for arrays of objects. The normalize_config_values
function now properly handles arrays containing objects (like image_config.images)
by recursively normalizing each object in the array using the items schema properties.

This resolves the 'configuration validation failed' error when saving static
image plugin configuration with multiple images.

* fix(plugins): Handle union types in config normalization and form generation

Fix configuration validation for fields with union types like ['integer', 'null'].
The normalization function now properly handles:
- Union types in top-level fields (e.g., random_seed: ['integer', 'null'])
- Union types in array items
- Empty string to None conversion for nullable fields
- Form generation and submission for union types

This resolves validation errors when saving plugin configs with nullable
integer/number fields (e.g., rotation_settings.random_seed in static-image plugin).

Also improves UX by:
- Adding placeholder text for nullable fields explaining empty = use default
- Properly handling empty values in form submission for union types

* fix(plugins): Improve union type normalization with better edge case handling

Enhanced normalization for union types like ['integer', 'null']:
- Better handling of whitespace in string values
- More robust empty string to None conversion
- Fallback to None when conversion fails and null is allowed
- Added debug logging for troubleshooting normalization issues
- Improved handling of nested object fields with union types

This should resolve remaining validation errors for nullable integer/number
fields in nested objects (e.g., rotation_settings.random_seed).

* chore: Add ledmatrix-news plugin to .gitignore exceptions

* Fix web interface service script path in install_service.sh

- Updated ExecStart path from start_web_conditionally.py to scripts/utils/start_web_conditionally.py
- Updated diagnose_web_ui.sh to check for correct script path
- Fixes issue where web UI service fails to start due to incorrect script path

* Fix nested configuration section headers not expanding

Fixed toggleNestedSection function to properly calculate scrollHeight when
expanding nested configuration sections. The issue occurred when sections
started with display:none - the scrollHeight was being measured before the
browser had a chance to lay out the element, resulting in a value of 0.

Changes:
- Added setTimeout to delay scrollHeight measurement until after layout
- Added overflow handling during animations to prevent content jumping
- Added fallback for edge cases where scrollHeight might still be 0
- Set maxHeight to 'none' after expansion completes for natural growth
- Updated function in both base.html and plugins_manager.js

This fix applies to all plugins with nested configuration sections, including:
- Hockey/Football/Basketball/Baseball/Soccer scoreboards (customization, global sections)
- All plugins with transition, display, and other nested configuration objects

Fixes configuration header expansion issues across all plugins.

* Fix syntax error in first_time_install.sh step 8.5

Added missing 'fi' statement to close the if block in the WiFi monitor
service installation section. This resolves the 'unexpected end of file'
error that occurred at line 1385 during step 8.5.

- Defer plugin discovery until first API request (removed from startup)
- Add lazy loading to operation queue, state manager, and operation history
- Defer health monitor initialization until first request
- Fix cache directory permission issue:
  - Add systemd CacheDirectory feature for automatic cache dir creation
  - Add manual cache directory creation in install script as fallback
  - Improve cache manager logging (reduce alarming warnings)
- Fix syntax errors in wifi_manager.py (unclosed try blocks)

These changes significantly improve web UI startup time, especially with many
plugins installed, while maintaining full backward compatibility.

* feat(plugins): Improve GitHub token pop-up UX and combine warning/settings

- Fix visibility toggle to handle inline styles properly

- Make NetworkManager restart conditional (only for hostapd mode)
- Add enhanced WiFi radio enable with retry and verification logic
- Add connectivity safety check before NetworkManager restart
- Ensure WiFi radio enabled after all AP mode disable operations
- Fix indentation bug in dnsmasq backup restoration logic

Fixes issue where WiFi radio was being disabled when disabling AP mode,
especially when connected via Ethernet, making it impossible to enable
WiFi from the web UI.

* fix(plugin-templates): Fix unreachable fallback to expired cache in update() method

The exception handler in update() checked the cached variable, which would
always be None or falsy at that point. If fresh cached data existed, the
method returned early. If cached data was expired, it was filtered out by
max_age constraint. The fix retrieves cached data again in the exception
handler with a very large max_age (1 year) to effectively bypass expiration
check and allow fallback to expired data when fetch fails.

* fix(plugin-templates): Resolve plugin_id mismatch in test template setUp method

* feat(plugins): Standardize manifest version fields schema

- Consolidate version fields to use consistent naming:
  - compatible_versions: array of semver ranges (required)

* chore: Add GitHub sponsor button configuration

* fix(wifi): Fix aggressive AP mode enabling and improve WiFi detection

Critical fixes:
- Change auto_enable_ap_mode default from True to False (manual enable only)
- Fixes issue where Pi would disconnect from network after code updates
- Matches documented behavior (was incorrectly defaulting to True in code)

Improvements:
- Add grace period: require 3 consecutive disconnected checks (90s) before enabling AP mode
- Prevents AP mode from enabling on transient network hiccups
- Improve WiFi status detection with retry logic and better nmcli parsing
- Enhanced logging for debugging WiFi connection issues
- Better handling of WiFi device detection (works with any wlan device)

This prevents the WiFi monitor from aggressively enabling AP mode and
disconnecting the Pi from the network when there are brief network issues
or during system initialization.

* fix(wifi): Revert auto_enable_ap_mode default to True with grace period protection

Change default back to True for auto_enable_ap_mode while keeping the grace
period protection that prevents interrupting valid WiFi connections.

- Default auto_enable_ap_mode back to True (useful for setup scenarios)
- Grace period (3 consecutive checks = 90s) prevents false positives
- Improved WiFi detection with retry logic ensures accurate status
- AP mode will auto-enable when truly disconnected, but won't interrupt
  valid connections due to transient detection issues

* fix(news): Update submodule reference for manifest fix

Update ledmatrix-news submodule to include the fixed manifest.json with
required entry_point and class_name fields.

* fix(wifi): Make AP mode open network and fix WiFi page loading in AP mode

AP Mode Changes:
- Remove password requirement from AP mode (open network for easier setup)
- Update hostapd config to create open network (no WPA/WPA2)
- Update nmcli hotspot to create open network (no password parameter)

WiFi Page Loading Fixes:
- Download local copies of HTMX and Alpine.js libraries
- Auto-detect AP mode (192.168.4.x) and use local JS files instead of CDN
- Auto-open WiFi tab when accessing via AP mode IP
- Add fallback loading if HTMX fails to load
- Ensures WiFi setup page works in AP mode without internet access

This fixes the issue where the WiFi page wouldn't load on iPhone when
accessing via AP mode (192.168.4.1:5000) because CDN resources couldn't
be fetched without internet connectivity.

* feat(wifi): Add explicit network switching support with clean disconnection

WiFi Manager Improvements:
- Explicitly disconnect from current network before connecting to a new one
- Add skip_ap_check parameter to disconnect_from_network() to prevent AP mode
  from activating during network switches
- Check if already connected to target network to avoid unnecessary work
- Improved logging for network switching operations

Web UI Improvements:
- Detect and display network switching status in UI
- Show 'Switching from [old] to [new]...' message when switching networks
- Enhanced status reloading after connection (multiple checks at 2s, 5s, 10s)
- Better user feedback during network transitions

This ensures clean network switching without AP mode interruptions and
provides clear feedback to users when changing WiFi networks.

* fix(web-ui): Add fallback content loading when HTMX fails to load

Problem:
- After recent updates, web UI showed navigation and CPU status but main
  content tabs never loaded
- Content tabs depend on HTMX's 'revealed' trigger to load
- If HTMX failed to load or initialize, content would never appear

Solutions:
- Enhanced HTMX loading verification with timeout checks
- Added fallback direct fetch for overview tab if HTMX fails
- Added automatic tab content loading when tabs change
- Added loadTabContent() method to manually trigger content loading
- Added global 'htmx-load-failed' event for error handling
- Automatic retry after 5 seconds if HTMX isn't available
- Better error messages and console logging for debugging

This ensures the web UI loads content even if HTMX has issues,
providing graceful degradation and better user experience.

* feat(web-ui): Add support for additionalProperties object rendering

- Add handler for objects with additionalProperties containing object schemas
- Render dynamic category controls with enable/disable toggles
- Display category metadata (display name, data file path)
- Used by of-the-day plugin for category management

* fix(wifi): Ensure AP mode hotspot is always open (no password)

Problem:
- LEDMatrix-Setup WiFi AP was still asking for password despite code changes
- Existing hotspot connections with passwords weren't being fully cleaned up
- NetworkManager might reuse old connection profiles with passwords

Solutions:
- More thorough cleanup: Delete all hotspot-related connections, not just known names
- Verification: Check if hotspot has password after creation
- Automatic fix: Remove password and restart connection if security is detected
- Better logging: Log when password is detected and removed

This ensures the AP mode hotspot is always open for easy setup access,
even if there were previously saved connections with passwords.

* fix(wifi): Improve network switching reliability and device state handling

Problem:
- Pi failing to switch WiFi networks via web UI
- Connection attempts happening before device is ready
- Disconnect not fully completing before new connection attempt
- Connection name lookup issues when SSID doesn't match connection name

Solutions:
- Improved disconnect logic: Disconnect specific connection first, then device
- Device state verification: Wait for device to be ready (disconnected/unavailable) before connecting
- Better connection lookup: Search by SSID, not just connection name
- Increased wait times: 2 seconds for disconnect to complete
- State checking before activating existing connections
- Enhanced error handling and logging throughout

This ensures network switching works reliably by properly managing device
state transitions and using correct connection identifiers.

- Ensures plugin tabs appear immediately when plugins load, even before full implementation merges
- Fixes issue where plugin navigation bar wasn't working

* feat(api): Populate uploaded_files and categories from disk for of-the-day plugin

- Scan of_the_day directory for existing JSON files when loading config
- Populate uploaded_files array from files on disk
- Populate categories from files on disk if not in config
- Categories default to disabled, user can enable them
- Ensures existing JSON files (word_of_the_day.json, slovenian_word_of_the_day.json) appear in UI

* fix(api): Improve category merging logic for of-the-day plugin

- Preserve existing category enabled state when merging with files from disk
- Ensure all JSON files from disk appear in categories section
- Categories from files default to disabled, preserving user choices
- Properly merge existing config with scanned files

* fix(wifi): More aggressive password removal for AP mode hotspot

Problem:
- LEDMatrix-Setup network still asking for password despite previous fixes
- NetworkManager may add default security settings to hotspots
- Existing connections with passwords may not be fully cleaned up

Solutions:
- Always remove ALL security settings after creating hotspot (not just when detected)
- Remove multiple security settings: key-mgmt, psk, wep-key, auth-alg
- Verify security was removed and recreate connection if verification fails
- Improved cleanup: Delete connections by SSID match, not just by name
- Disconnect connections before deleting them
- Always restart connection after removing security to apply changes
- Better logging for debugging

This ensures the AP mode hotspot is always open, even if NetworkManager
tries to add default security settings.

All animations now GPU-accelerated (transform/opacity only).
Optimized for low-powered Raspberry Pi devices.

* fix(web): Resolve ReferenceError for getInstalledPluginsSafe in v3 stub initialization

Move getInstalledPluginsSafe() function definition before the app() stub code that uses it. The function was previously defined at line 3756 but was being called at line 849 during Alpine.js initialization, causing a ReferenceError when loadInstalledPluginsDirectly() attempted to load plugins before the full implementation was ready.

* fix(web): Resolve TypeError for installedPlugins.map in plugin loading

Fix PluginAPI.getInstalledPlugins() to properly extract plugins array from API response structure. The API returns {status: 'success', data: {plugins: [...]}}, but the method was returning response.data (the object) instead of response.data.plugins (the array).

Changes:
- api_client.js: Extract plugins array from response.data.plugins
- plugins_manager.js: Add defensive array checks and handle array return value correctly
- base.html: Add defensive check in getInstalledPluginsSafe() to ensure plugins is always an array

This prevents 'installedPlugins.map is not a function' errors when loading plugins.

* style(web-ui): Enhance navigation bar styling for better readability

- Improve contrast: Change inactive tab text from gray-500 to gray-700
- Add gradient background and thicker border for active tabs
- Enhance hover states with background highlights
- Add smooth transitions using GPU-accelerated properties

All changes are CSS-only with zero performance overhead.

* fix(web-ui): Optimize plugin loading and reduce initialization errors

- Make generateConfigForm accessible to inline Alpine components via parent scope
- Consolidate plugin initialization to prevent duplicate API calls
- Fix script execution from HTMX-loaded content by extracting scripts before DOM insertion
- Add request deduplication to loadInstalledPlugins() to prevent concurrent requests
- Improve Alpine component initialization with proper guards and fallbacks

This eliminates 'generateConfigForm is not defined' errors and reduces plugin
API calls from 3-4 duplicate calls to 1 per page load, significantly improving
page load performance.

* fix(web-ui): Add guard check for generateConfigForm to prevent Alpine errors

Add typeof check in x-show to prevent Alpine from evaluating generateConfigForm
before the component methods are fully initialized. This eliminates the
'generateConfigForm is not defined' error that was occurring during component
initialization.

* fix(web-ui): Fix try-catch block structure in script execution code

Correct the nesting of try-catch block inside the if statement for script execution.
The catch block was incorrectly placed after the else clause, causing a syntax error.

* fix(web-ui): Escape quotes in querySelector to avoid HTML attribute conflicts

Change double quotes to single quotes in the CSS selector to prevent conflicts
with HTML attribute parsing when the x-data expression is embedded.

* style(web): Improve button text readability in Quick Actions section

* fix(web): Resolve Alpine.js expression errors in plugin configuration component

- Capture plugin from parent scope into component data to fix parsing errors
- Update all plugin references to use this.plugin in component methods
- Fix x-init to properly call loadPluginConfig method
- Resolves 'Uncaught ReferenceError' for isOnDemandLoading, onDemandLastUpdated, and other component properties

* fix(web): Fix remaining Alpine.js scope issues in plugin configuration

- Use this.generateConfigForm in typeof checks and method calls
- Fix form submission to use this.plugin.id
- Use $root. prefix for parent scope function calls (refreshPlugin, updatePlugin, etc.)
- Fix confirm dialog string interpolation
- Ensures all component methods and properties are properly scoped

* fix(web): Add this. prefix to all Alpine.js component property references

- Fix all template expressions to use this. prefix for component properties
- Update isOnDemandLoading, onDemandLastUpdated, onDemandRefreshing references
- Update onDemandStatusClass, onDemandStatusText, onDemandServiceClass, onDemandServiceText
- Update disableRunButton, canStopOnDemand, showEnableHint, loading references
- Ensures Alpine.js can properly resolve all component getters and properties

* fix(web): Resolve Alpine.js expression errors in plugin configuration

- Move complex x-data object to pluginConfigData() function for better parsing
- Fix all template expressions to use this.plugin instead of plugin
- Add this. prefix to all method calls in event handlers
- Fix duplicate x-on:click attribute on uninstall button
- Add proper loading state management in loadPluginConfig method

This resolves the 'Invalid or unexpected token' and 'Uncaught ReferenceError'
errors in the browser console.

* fix(web): Fix plugin undefined errors in Alpine.js plugin configuration

- Change x-data initialization to capture plugin from loop scope first
- Use Object.assign in x-init to merge pluginConfigData properties
- Add safety check in pluginConfigData function for undefined plugins
- Ensure plugin is available before accessing properties in expressions

This resolves the 'Cannot read properties of undefined' errors by ensuring
the plugin object is properly captured from the x-for loop scope before
any template expressions try to access it.

* style(web): Make Quick Actions button text styling consistent

- Update Start Display, Stop Display, and Reboot System buttons
- Change from text-sm font-medium to text-base font-semibold
- All Quick Actions buttons now have consistent bold, larger text
- Matches the styling of Update Code, Restart Display Service, and Restart Web Service buttons

* fix(wifi): Properly handle AP mode disable during WiFi connection

- Check return value of disable_ap_mode() before proceeding with connection
- Add verification loop to ensure AP mode is actually disabled
- Increase wait time to 5 seconds for NetworkManager restart stabilization
- Return clear error messages if AP mode cannot be disabled
- Prevents connection failures when switching networks from web UI or AP mode

This fixes the issue where WiFi network switching would fail silently when
AP mode disable failed, leaving the system in an inconsistent state.

* fix(web): Handle API response errors in plugin configuration loading

- Add null/undefined checks before accessing API response status
- Set fallback defaults when API responses don't have status 'success'
- Add error handling for batch API requests with fallback to individual requests
- Add .catch() handlers to individual fetch calls to prevent unhandled rejections
- Add console warnings to help debug API response failures
- Fix applies to both main loadPluginConfig and PluginConfigHelpers.loadPluginConfig

This fixes the issue where plugin configuration sections would get stuck
showing the loading animation when API responses failed or returned error status.

* fix(web): Fix Alpine.js reactivity for plugin config by using direct x-data

Changed from Object.assign pattern to direct x-data assignment to ensure
Alpine.js properly tracks reactive properties. The previous approach used
Object.assign to merge properties into the component after initialization,
which caused Alpine to not detect changes to config/schema properties.

The fix uses pluginConfigData(plugin) directly as x-data, ensuring all
properties including config, schema, loading, etc. are reactive from
component initialization.

* fix(web): Ensure plugin variable is captured in x-data scope

Use spread operator to merge pluginConfigData properties while explicitly
capturing the plugin variable from outer x-for scope. This fixes undefined
plugin errors when Alpine evaluates the component data.

* fix(web): Use $data for Alpine.js reactivity when merging plugin config

Use Object.assign with Alpine's $data reactive proxy instead of this to
ensure added properties are properly reactive. This fixes the issue where
plugin variable scoping from x-for wasn't accessible in x-data expressions.

* fix(web): Remove incorrect 'this.' prefix in Alpine.js template expressions

Alpine.js template expressions (x-show, x-html, x-text, x-on) use the
component data as the implicit context, so 'this.' prefix is incorrect.
In template expressions, 'this' refers to the DOM element, not the
component data.

Changes:
- Replace 'this.plugin.' with 'plugin.' in all template expressions (19 instances)
- Replace 'this.loading' with 'loading' in x-show directives
- Replace 'this.generateConfigForm' with 'generateConfigForm' in x-show/x-html
- Replace 'this.savePluginConfig' with 'savePluginConfig' in x-on:submit
- Replace 'this.config/schema/webUiActions' with direct property access
- Use '$data.loadPluginConfig' in x-init for explicit method call

Note: 'this.' is still correct inside JavaScript method definitions within
pluginConfigData() function since those run with proper object context.

* fix(web): Prevent infinite recursion in plugin config methods

Add 'parent !== this' check to loadPluginConfig, generateConfigForm, and
savePluginConfig methods in pluginConfigData to prevent infinite recursion
when the component tries to delegate to a parent that resolves to itself.

This fixes the 'Maximum call stack size exceeded' error that occurred when
the nested Alpine component's $root reference resolved to a component that
had the same delegating methods via Object.assign.

* fix(web): Resolve infinite recursion in plugin config by calling $root directly

The previous implementation had delegating methods (generateConfigForm,
savePluginConfig) in pluginConfigData that tried to call parent.method(),
but the parent detection via getParentApp() was causing circular calls
because multiple components had the same methods.

Changes:
- Template now calls $root.generateConfigForm() and $root.savePluginConfig()
  directly instead of going through nested component delegation
- Removed delegating generateConfigForm and savePluginConfig from pluginConfigData
- Removed getParentApp() helper that was enabling the circular calls
- Simplified loadPluginConfig to use PluginConfigHelpers directly

This fixes the 'Maximum call stack size exceeded' error when rendering
plugin configuration forms.

* fix(web): Use window.PluginConfigHelpers instead of $root for plugin config

The $root magic variable in Alpine.js doesn't correctly reference the
app() component's data scope from nested x-data contexts. This causes
generateConfigForm and savePluginConfig to be undefined.

Changed to use window.PluginConfigHelpers which has explicit logic to
find and use the app component's methods.

* fix(web): Use direct x-data initialization for plugin config reactivity

Changed from Object.assign($data, pluginConfigData(plugin)) to
x-data="pluginConfigData(plugin)" to ensure Alpine.js properly
tracks reactivity for all plugin config properties. This fixes
the issue where all plugin tabs were showing the same config.

* refactor(web): Implement server-side plugin config rendering with HTMX

Major architectural improvement to plugin configuration management:

- Add server-side Jinja2 template for plugin config forms
  (web_interface/templates/v3/partials/plugin_config.html)
- Add Flask route to serve plugin config partials on-demand
- Replace complex client-side form generation with HTMX lazy loading
- Add Alpine.js store for centralized plugin state management
- Mark old pluginConfigData and PluginConfigHelpers as deprecated

Benefits:
- Lazy loading: configs only load when tab is accessed
- Server-side rendering: reduces client-side complexity
- Better performance: especially on Raspberry Pi
- Cleaner code: Jinja2 macros replace JS string templates
- More maintainable: form logic in one place (server)

The old client-side code is preserved for backwards compatibility
but is no longer used by the main plugin configuration UI.

* fix(web): Trigger HTMX manually after Alpine renders plugin tabs

HTMX processes attributes at page load time, before Alpine.js
renders dynamic content. Changed from :hx-get attribute to
x-init with htmx.ajax() to properly trigger the request after
the element is rendered.

* fix(web): Remove duplicate 'enabled' toggle from plugin config form

The 'enabled' field was appearing twice in plugin configuration:
1. Header toggle (quick action, uses HTMX)
2. Configuration form (from schema, requires save)

Now only the header toggle is shown, avoiding user confusion.
The 'enabled' key is explicitly skipped when rendering schema properties.

* perf(web): Optimize plugin manager with request caching and init guards

Major performance improvements to plugins_manager.js:

1. Request Deduplication & Caching
   - Added pluginLoadCache with 3-second TTL
   - Subsequent calls return cached data instead of making API requests
   - In-flight request deduplication prevents parallel duplicate fetches
   - Added refreshInstalledPlugins() for explicit force-refresh

2. Initialization Guards
   - Added pluginsInitialized flag to prevent multiple initializePlugins() calls
   - Added _eventDelegationSetup guard on container to prevent duplicate listeners
   - Added _listenerSetup guards on search/category inputs

3. Debug Logging Control
   - Added PLUGIN_DEBUG flag (localStorage.setItem('pluginDebug', 'true'))
   - Most console.log calls now use pluginLog() which only logs when debug enabled
   - Reduces console noise from ~150 logs to ~10 in production

Expected improvements:
- API calls reduced from 6+ to 2 on page load
- Event listeners no longer duplicated
- Cleaner console output
- Faster perceived performance

* fix(web): Handle missing search elements in searchPluginStore

The searchPluginStore function was failing silently when called before
the plugin-search and plugin-category elements existed in the DOM.
This caused the plugin store to never load.

Now safely checks if elements exist before accessing their values.

* fix(web): Ensure plugin store loads via pluginManager.searchPluginStore

- Exposed searchPluginStore on window.pluginManager for easier access
- Updated base.html to fallback to pluginManager.searchPluginStore
- Added logging when loading plugin store

* fix(web): Expose searchPluginStore from inside the IIFE

The function was defined inside the IIFE but only exposed after the IIFE
ended, where the function was out of scope. Now exposed immediately after
definition inside the IIFE.

* fix(web): Add cache-busting version to plugins_manager.js URL

Static JS files were being aggressively cached, preventing updates
from being loaded by browsers.

* fix(web): Fix pluginLog reference error outside IIFE

pluginLog is defined inside the IIFE, so use _PLUGIN_DEBUG_EARLY and
console.log directly for code outside the IIFE.

* chore(web): Update plugins_manager.js cache version

* fix(web): Defer plugin store render when grid not ready

Instead of showing an error when plugin-store-grid doesn't exist,
store plugins in window.__pendingStorePlugins for later rendering
when the tab loads (consistent with how installed plugins work).

* chore: Bump JS cache version

* fix(web): Restore enabledBool variable in plugin render

Variable was removed during debug logging optimization but was still
being used in the template string for toggle switch rendering.

* fix(ui): Add header and improve categories section rendering

- Add proper header (h4) to categories section with label
- Add debug logging to diagnose categories field rendering
- Improve additionalProperties condition check readability

* fix(ui): Improve additionalProperties condition check

- Explicitly exclude objects with properties to avoid conflicts
- Ensure categories section is properly detected and rendered
- Categories should show as header with toggles, not text box

* fix(web-ui): Fix JSON parsing errors and default value loading for plugin configs

- Fix JSON parsing errors when saving file upload fields by properly unescaping HTML entities
- Merge config with schema defaults when loading plugin config so form shows default values
- Improve default value handling in form generation for nested objects and arrays
- Add better error handling for malformed JSON in file upload fields

* fix(plugins): Return plugins array from getInstalledPlugins() instead of data object

Fixed PluginAPI.getInstalledPlugins() to return response.data.plugins (array)
instead of response.data (object). This was preventing window.installedPlugins
from being set correctly, which caused plugin configuration tabs to not appear
and prevented users from saving plugin configurations via the web UI.

The fix ensures that:
- window.installedPlugins is properly populated with plugin array
- Plugin tabs are created automatically on page load
- Configuration forms and save buttons are rendered correctly
- Save functionality works as expected

* fix(api): Support form data submission for plugin config saves

The HTMX form submissions use application/x-www-form-urlencoded format
instead of JSON. This update allows the /api/v3/plugins/config POST
endpoint to accept both formats:

- JSON: plugin_id and config in request body (existing behavior)
- Form data: plugin_id from query string, config fields from form

Added _parse_form_value helper to properly convert form strings to
appropriate Python types (bool, int, float, JSON arrays/objects).

* debug: Add form data logging to diagnose config save issue

* fix(web): Re-discover plugins before loading config partial

The plugin config partial was returning 'not found' for plugins
because the plugin manifests weren't loaded. The installed plugins
API was working because it calls discover_plugins() first.

Changes:
- Add discover_plugins() call in _load_plugin_config_partial when
  plugin info is not found on first try
- Remove debug logging from form data handling

* fix(web): Comprehensive plugin config save improvements

SWEEPING FIX for plugin configuration saving issues:

1. Form data now MERGES with existing config instead of replacing
   - Partial form submissions (missing fields) no longer wipe out
     existing config values
   - Fixes plugins with complex schemas (football, clock, etc.)

2. Improved nested value handling with _set_nested_value helper
   - Correctly handles deeply nested structures like customization
   - Properly merges when intermediate objects already exist

3. Better JSON parsing for arrays
   - RGB color arrays like [255, 0, 0] now parse correctly
   - Parse JSON before trying number conversion

4. Bump cache version to force JS reload

* fix(web): Add early stubs for updatePlugin and uninstallPlugin

Ensures these functions are available immediately when the page loads,
even before the full IIFE executes. Provides immediate user feedback
and makes API calls directly.

This fixes the 'Update button does not work' issue by ensuring the
function is always defined and callable.

* fix(web): Support form data in toggle endpoint

The toggle endpoint now accepts both JSON and HTMX form submissions.
Also updated the plugin config template to send the enabled state
via hx-vals when the checkbox changes.

Fixes: 415 Unsupported Media Type error when toggling plugins

* fix(web): Prevent config duplication when toggling plugins

Changed handleToggleResponse to update UI in place instead of
refreshing the entire config partial, which was causing duplication.

Also improved refreshPluginConfig with proper container targeting
and concurrent refresh prevention (though it's no longer needed
for toggles since we update in place).

* fix(api): Schema-aware form value parsing for plugin configs

Major fix for plugin config saving issues:

1. Load schema BEFORE processing form data to enable type-aware parsing
2. New _parse_form_value_with_schema() function that:
   - Converts comma-separated strings to arrays when schema says 'array'
   - Parses JSON strings for arrays/objects
   - Handles empty strings for arrays (returns [] instead of None)
   - Uses schema to determine correct number types
3. Post-processing to ensure None arrays get converted to empty arrays
4. Proper handling of nested object fields

Fixes validation errors:
- 'category_order': Expected type array, got str
- 'categories': Expected type object, got str
- 'uploaded_files': Expected type array, got NoneType
- RGB color arrays: Expected type array, got str

* fix(web): Make plugin config handlers idempotent and remove scripts from HTMX partials

CRITICAL FIX for script redeclaration errors:

1. Removed all <script> tags from plugin_config.html partial
   - Scripts were being re-executed on every HTMX swap
   - Caused 'Identifier already declared' errors

2. Moved all handler functions to base.html with idempotent initialization
   - Added window.__pluginConfigHandlersInitialized guard
   - Functions only initialized once, even if script runs multiple times
   - All state stored on window object (e.g., window.pluginConfigRefreshInProgress)

3. Enhanced error logging:
   - Client-side: Logs form payload, response status, and parsed error details
   - Server-side: Logs raw form data and parsed config on validation failures

4. Functions moved to window scope:
   - toggleSection
   - handleConfigSave (with detailed error logging)
   - handleToggleResponse (updates UI in place, no refresh)
   - handlePluginUpdate
   - refreshPluginConfig (with duplicate prevention)
   - runPluginOnDemand
   - stopOnDemand
   - executePluginAction

This ensures HTMX-swapped fragments only contain HTML, and all
scripts run once in the base layout.

* fix(api): Filter config to only schema-defined fields before validation

When merging with existing_config, fields not in the plugin's schema
(like high_performance_transitions, transition, dynamic_duration)
were being preserved, causing validation failures when
additionalProperties is false.

Add _filter_config_by_schema() function to recursively filter config
to only include fields defined in the schema before validation.

This fixes validation errors like:
- 'Additional properties are not allowed (high_performance_transitions, transition were unexpected)'

* fix(web): Improve update plugin error handling and support form data

1. Enhanced updatePlugin JavaScript function:
   - Validates pluginId before sending request
   - Checks response.ok before parsing JSON
   - Better error logging with request/response details
   - Handles both successful and error responses properly

2. Update endpoint now supports both JSON and form data:
   - Similar to config endpoint, accepts plugin_id from query string or form
   - Better error messages and debug logging

3. Prevent duplicate function definitions:
   - Second updatePlugin definition checks if improved version exists
   - Both definitions now have consistent error handling

Fixes: 400 BAD REQUEST 'Request body must be valid JSON' error

* fix(web): Show correct 'update' message instead of 'save' for plugin updates

The handlePluginUpdate function now:
1. Checks actual HTTP status code (not just event.detail.successful)
2. Parses JSON response to get server's actual message
3. Replaces 'save' with 'update' if message incorrectly says 'save'

Fixes: Update button showing 'saved successfully' instead of
'updated successfully'

* fix(web): Execute plugin updates immediately instead of queuing

Plugin updates are now executed directly (synchronously) instead of
being queued for async processing. This provides immediate feedback
to users about whether the update succeeded or failed.

Updates are fast git pull operations, so they don't need async
processing. The operation queue is reserved for longer operations
like install/uninstall.

Fixes: Update button not actually updating plugins (operations were
queued but users didn't see results)

* fix(web): Ensure toggleSection function is always available for collapsible headers

Moved toggleSection outside the initialization guard block so it's
always defined, even if the plugin config handlers have already been
initialized. This ensures collapsible sections in plugin config forms
work correctly.

Added debug logging to help diagnose if sections/icons aren't found.

Fixes: Collapsible headers in plugin config schema not collapsing

* fix(web): Improve toggleSection to explicitly show/hide collapsible content

Changed from classList.toggle() to explicit add/remove of 'hidden' class
based on current state. This ensures the content visibility is properly
controlled when collapsing/expanding sections.

Added better error checking and state detection for more reliable
collapsible section behavior.

* fix(web): Load plugin tabs on page load instead of waiting for plugin manager tab click

The stub's loadInstalledPlugins was an empty function, so plugin tabs
weren't loading until the plugin manager tab was clicked. Now the stub
implementation:
1. Tries to use global window.loadInstalledPlugins if available
2. Falls back to window.pluginManager.loadInstalledPlugins
3. Finally falls back to direct loading via loadInstalledPluginsDirectly
4. Always updates tabs after loading plugins

This ensures plugin navigation tabs are available immediately on page load.

Fixes: Plugin tabs only loading after clicking plugin manager tab

* fix(web): Ensure plugin navigation tabs load on any page regardless of active tab

Multiple improvements to ensure plugin tabs are always visible:

1. Stub's loadInstalledPluginsDirectly now waits for DOM to be ready
   before updating tabs, using requestAnimationFrame for proper timing

2. Stub's init() now has a retry mechanism that periodically checks
   if plugins have been loaded by plugins_manager.js and updates tabs
   accordingly (checks for 2 seconds)

3. Full implementation's init() now properly handles async plugin loading
   and ensures tabs are updated after loading completes, checking
   window.installedPlugins first before attempting to load

4. Both stub and full implementation ensure tabs update using $nextTick
   to wait for Alpine.js rendering cycle

This ensures plugin navigation tabs are visible immediately when the
page loads, regardless of whether the user is on overview, plugin manager,
or any other tab.

Fixes: Plugin tabs only appearing after clicking plugin manager tab

* fix(web): Fix restart display button not working

The initPluginsPage function was returning early before event listeners
were set up, making all the event listener code unreachable. Moved the
return statement to after all event listeners are attached.

This fixes the restart display button and all other buttons in the
plugin manager (refresh plugins, update all, search, etc.) that depend
on event listeners being set up.

Fixes: Restart Display button not working in plugin manager

* fix(web-ui): Improve categories field rendering for of-the-day plugin

- Add more explicit condition checking for additionalProperties objects
- Add debug logging specifically for categories field
- Add fallback handler for objects that don't match special cases (render as JSON textarea)
- Ensure categories section displays correctly with toggle cards instead of plain text

* fix(install): Prevent following broken symlinks during file ownership setup

- Add -P flag to find commands to prevent following symlinks when traversing
- Add -h flag to chown to operate on symlinks themselves rather than targets
- Exclude scripts/dev/plugins directory which contains development symlinks
- Fixes error when chown tries to dereference broken symlinks with extra LEDMatrix in path

* fix(scroll): Ensure scroll completes fully before switching displays

- Add display_width to total scroll distance calculation
- Scroll now continues until content is completely off screen
- Update scroll completion check to use total_scroll_width + display_width
- Prevents scroll from being cut off mid-way when switching to next display

* fix(install): Remove unsupported -P flag from find commands

- Remove -P flag which is not supported on all find versions
- Keep -h flag on chown to operate on symlinks themselves
- Change to {} \; syntax for better error handling
- Add error suppression to continue on broken symlinks
- Exclude scripts/dev/plugins directory to prevent traversal into broken symlinks

* docs(wifi): Add trailing newline to WiFi AP failover setup guide

* fix(web): Suppress non-critical socket errors and fix WiFi permissions script

- Add error filtering in web interface to suppress harmless client disconnection errors
- Downgrade 'No route to host' and broken pipe errors from ERROR to DEBUG level
- Fix WiFi permissions script to use mktemp instead of manual temp file creation
- Add cleanup trap to ensure temp files are removed on script exit
- Resolves permission denied errors when creating temp files during installation

* fix(web): Ensure plugin navigation tabs load on any page by dispatching events

The issue was that when plugins_manager.js loaded and called
loadInstalledPlugins(), it would set window.installedPlugins but the
Alpine.js component wouldn't know to update its tabs unless the plugin
manager tab was clicked.

Changes:
1. loadInstalledPlugins() now always dispatches a 'pluginsUpdated' event
   when it sets window.installedPlugins, not just when plugin IDs change
2. renderInstalledPlugins() also dispatches the event and always updates
   window.installedPlugins for reactivity
3. Cached plugin data also dispatches the event when returned

The Alpine component already listens for the 'pluginsUpdated' event in
its init() method, so tabs will now update immediately when plugins are
loaded, regardless of which tab is active.

Fixes: Plugin navigation tabs only loading after clicking plugin manager tab

* fix(web): Improve input field contrast in plugin configuration forms

Changed input backgrounds from bg-gray-800 to bg-gray-900 (darker) to
ensure high contrast with white text. Added placeholder:text-gray-400
for better placeholder text visibility.

Updated in both server-side template (plugin_config.html) and client-side
form generation (plugins_manager.js):
- Number inputs
- Text inputs
- Array inputs (comma-separated)
- Select dropdowns
- Textareas (JSON objects)
- Fallback inputs without schema

This ensures all form inputs have high contrast white text on dark
background, making them clearly visible and readable.

Fixes: White text on white background in plugin config inputs

* fix(web): Change plugin config input text from white to black

Changed all input fields in plugin configuration forms to use black text
on white background instead of white text on dark background for better
readability and standard form appearance.

Updated:
- Input backgrounds: bg-gray-900 -> bg-white
- Text color: text-white -> text-black
- Placeholder color: text-gray-400 -> text-gray-500

Applied to both server-side template and client-side form generation
for all input types (number, text, select, textarea).

* fix(web): Ensure toggleSection function is available for plugin config collapsible sections

Moved toggleSection function definition to an early script block so it's
available immediately when HTMX loads plugin configuration content. The
function was previously defined later in the page which could cause it
to not be accessible when inline onclick handlers try to call it.

The function toggles the 'hidden' class on collapsible section content
divs and rotates the chevron icon between right (collapsed) and down
(expanded) states.

Fixes: Plugin configuration section headers not collapsing/expanding

* fix(web): Fix collapsible section toggle to properly hide/show content

Updated toggleSection function to explicitly set display style in addition
to toggling the hidden class. This ensures the content is properly hidden
even if CSS specificity or other styles might interfere with just the
hidden class.

The function now:
- Checks both the hidden class and computed display style
- Explicitly sets display: '' when showing and display: 'none' when hiding
- Rotates chevron icon between right (collapsed) and down (expanded)

This ensures collapsible sections in plugin configuration forms properly
hide and show their content when the header is clicked.

Fixes: Collapsible section headers rotate chevron but don't hide content

* fix(web): Fix collapsible section toggle to work on first click

Simplified the toggle logic to rely primarily on the 'hidden' class check
rather than mixing it with computed display styles. When hiding, we now
remove any inline display style to let Tailwind's 'hidden' class properly
control the display property.

This ensures sections respond correctly on the first click, whether they're
starting in a collapsed or expanded state.

Fixes: Sections requiring 2 clicks to collapse

* fix(web): Ensure collapsible sections start collapsed by default

Added explicit display: none style to nested content divs in plugin config
template to ensure they start collapsed. The hidden class should handle this,
but adding the inline style ensures sections are definitely collapsed on
initial page load.

Sections now:
- Start collapsed (hidden) with chevron pointing right
- Expand when clicked (chevron points down)
- Collapse when clicked again (chevron points right)

This ensures a consistent collapsed initial state across all plugin
configuration sections.

* fix(web): Fix collapsible section toggle to properly collapse on second click

Fixed the toggle logic to explicitly set display: block when showing and
display: none when hiding, rather than clearing the display style. This
ensures the section state is properly tracked and the toggle works correctly
on both expand and collapse clicks.

The function now:
- When hidden: removes hidden class, sets display: block, chevron down
- When visible: adds hidden class, sets display: none, chevron right

This fixes the issue where sections would expand but not collapse again.

Fixes: Sections not collapsing on second click

* feat(web): Ensure plugin navigation tabs load automatically on any page

Implemented comprehensive solution to ensure plugin navigation tabs load
automatically without requiring a visit to the plugin manager page:

1. Global event listener for 'pluginsUpdated' - works even if Alpine isn't
   ready yet, updates tabs directly when plugins_manager.js loads plugins

2. Enhanced stub's loadInstalledPluginsDirectly():
   - Sets window.installedPlugins after loading
   - Dispatches 'pluginsUpdated' event for global listener
   - Adds console logging for debugging

3. Event listener in stub's init() method:
   - Listens for 'pluginsUpdated' events
   - Updates component state and tabs when events fire

4. Fallback timer:
   - If plugins_manager.js hasn't loaded after 2 seconds, fetches
     plugins directly via API
   - Ensures tabs appear even if plugins_manager.js fails

5. Improved checkAndUpdateTabs():
   - Better logging
   - Fallback to direct fetch after timeout

6. Enhanced logging throughout plugin loading flow for debugging

This ensures plugin tabs are visible immediately on page load, regardless
of which tab is active or when plugins_manager.js loads.

Fixes: Plugin navigation tabs only loading after visiting plugin manager

* fix(web): Improve plugin tabs update logging and ensure immediate execution

Enhanced logging in updatePluginTabs() and _doUpdatePluginTabs() to help
debug why tabs aren't appearing. Changed debounce behavior to execute
immediately on first call to ensure tabs appear quickly.

Added detailed console logging with [FULL] prefix to track:
- When updatePluginTabs() is called
- When _doUpdatePluginTabs() executes
- DOM element availability
- Tab creation process
- Final tab count

This will help identify if tabs are being created but not visible, or if
the update function isn't being called at all.

Fixes: Plugin tabs loading but not visible in navigation bar

* fix(web): Prevent duplicate plugin tab updates and clearing

Added debouncing and duplicate prevention to stub's updatePluginTabs() to
prevent tabs from being cleared and re-added multiple times. Also checks
if tabs already match before clearing them.

Changes:
1. Debounce stub's updatePluginTabs() with 100ms delay
2. Check if existing tabs match current plugin list before clearing
3. Global event listener only triggers full implementation's updatePluginTabs
4. Stub's event listener only works in stub mode (before enhancement)

This prevents the issue where tabs were being cleared and re-added
multiple times in rapid succession, which could leave tabs empty.

Fixes: Plugin tabs being cleared and not re-added properly

* fix(web): Fix plugin tabs not rendering when plugins are loaded

Fixed _doUpdatePluginTabs() to properly use component's installedPlugins
instead of checking window.installedPlugins first. Also fixed the 'unchanged'
check to not skip when both lists are empty (first load scenario).

Changes:
1. Check component's installedPlugins first (most up-to-date)
2. Only skip update if plugins exist AND match (don't skip empty lists)
3. Retry if no plugins found (in case they're still loading)
4. Ensure window.installedPlugins is set when loading directly
5. Better logging to show which plugin source is being used

This ensures tabs are rendered when plugins are loaded, even on first page load.

Fixes: Plugin tabs not being drawn despite plugins being loaded

* fix(config): Fix array field parsing and validation for plugin config forms

- Added logic to detect and combine indexed array fields (text_color.0, text_color.1, etc.)
- Fixed array fields incorrectly stored as dicts with numeric keys
- Improved handling of comma-separated array values from form submissions
- Ensures array fields meet minItems requirements before validation
- Resolves 400 BAD REQUEST errors when saving plugin config with RGB color arrays

- Add validatePluginConfigForm function that shows which fields fail and why
- Automatically expands collapsed sections containing invalid fields
- Focuses first invalid field and scrolls to it
- Shows user-friendly error messages with field names and specific issues
- Prevents form submission until all fields are valid

* fix(schema): Remove core properties from required array during validation

- Core properties (enabled, display_duration, live_priority) are system-managed
- SchemaManager now removes them from required array after injection
- Added default values for core properties (enabled=True, display_duration=15, live_priority=False)
- Updated generate_default_config() to ensure live_priority has default
- Resolves 186 validation issues, reducing to 3 non-blocking warnings (98.4% reduction)
- All 19 of 20 plugins now pass validation without errors

Documentation:
- Created docs/PLUGIN_CONFIG_CORE_PROPERTIES.md explaining core property handling
- Updated existing docs to reflect core property behavior
- Removed temporary audit files and scripts

* fix(ui): Improve button text contrast on white backgrounds

- Changed Screenshot button text from text-gray-700 to text-gray-900
- Added global CSS rule to ensure all buttons with white backgrounds use dark text (text-gray-900) for better readability
- Fixes contrast issues where light text on light backgrounds was illegible

* fix(ui): Add explicit text color to form-control inputs

- Added color: #111827 to .form-control class to ensure dark text on white backgrounds
- Fixes issue where input fields had white text on white background after button contrast fix
- Ensures all form inputs are readable with proper contrast

* docs: Update impact explanation and plugin config documentation

  - Integrate display controller to read from /tmp/led_matrix_preview.png snapshot
  - Scan assets/fonts directory and extract font metadata with freetype

- Phase 1: Security & Input Validation

  - Add rate limiting (lenient for local use, prevents accidental abuse)
  - Add file upload validation to font upload endpoint

- Phase 3: Error Handling
  - Add global error handlers for 404, 500, and unhandled exceptions
