ChuckandClaude Opus 5.5 724673ba0b fix: one retry layer for background fetches; CI installs the web requirements; one Discord invite (#657)
- BackgroundDataService: the session adapter retried connection errors 3x
  inside each attempt of the service's own retry loop (up to 16 connection
  attempts per request on a dead network). The adapter no longer retries;
  ESPN date chunks, which bypass the loop and skip a failed chunk, get a
  small connection retry of their own (_ConnectionRetryingSession).
- CI installs web_interface/requirements.txt. The brotli header test now
  checks its intent (core never hand-sets br; requests may advertise it when
  a decoder is installed) instead of failing whenever brotli is present.
- Every Discord link uses the LEDMatrix server's invite (RdrC37rEag).

ChuckandClaude Opus 5.5 6cfcf2e384 fix(web): plugin dir resolver in routes, nmcli AP detection, daemon config reload, upload safety, BDF preview (#655)
* fix(web): plugin dir resolver in routes, nmcli AP detection, daemon config reload, upload safety

- Route plugin lookups (installed list, update, recorded version, config
  form, web UI pages) through the plugin manager's resolver so plugins in
  ledmatrix-<id> directories work.
- Captive-portal detection also sees the nmcli fallback AP (cached).
- WiFi monitor daemon re-reads wifi_config.json when its mtime changes.
- Drop the AP check in disconnect_from_network that could never fire.
- LED status file per WiFiManager; config path falls back to this checkout.
- BDF font preview via src.common.bdf_font.
- Asset uploads validate every file before saving; metadata and calendar
  credentials written atomically; no absolute path in the response;
  asset delete answers 400 for a missing body.
- Coerce string booleans in plugin toggle, on-demand start and AP force.
- SSE broadcaster clears its thread handle before exiting.
- start.py log filter handles every exc_info form.
- Cleanups: unused plugins/fonts partial work, duplicate backup catch-alls,
  raw-config error helper, update-route tidy, redundant imports.

* fix(web): request BDF font previews now that the server renders them

The Fonts tab skipped the preview request for .bdf files because the server
used to refuse them; /fonts/preview now draws BDF with the shared loader.

* fix(web): take the update route's plugin directory from a directory listing

CodeQL flagged the path built from the request's plugin_id (the id was
already validated with safe_path_component, which CodeQL doesn't model; the
same flow on main is alerts 738/739). The directory is now the entry of
plugins_dir matched by name, so nothing built from user input reaches the
filesystem; an id with nothing installed goes to the store manager, which
reports it not found as before.

* fix(web): read the blueprint's plugin_manager defensively in _plugin_directory

_get_plugin_version now goes through _plugin_directory, which read
api_v3.plugin_manager directly; the attribute exists only once the app sets
it, so test_path_traversal_guards::test_a_real_manifest_is_read failed
when run on its own (order-dependent in the full suite).

ChuckandClaude Opus 5.5 c00bf5e8e6 fix(plugin-system): unload/update race, failed-load cleanup, limits validation, schema lookup, install rollback (#653)
* fix(plugin-system): unload/update race, failed-load module cleanup, limits validation, schema lookup, install rollback, op-queue dedupe

- unload_plugin takes the per-plugin lock (5s bounded) before cleanup(),
  and an update() that finishes after its plugin was unloaded no longer
  sets the state back to ENABLED.
- A load that fails after import drops plugin_<id> and its submodules
  and forgets its manager fonts, so a fixed plugin reloads new code.
- Resource limits are validated as non-negative numbers: 400 at
  POST /plugins/limits, bad cached records ignored with one warning.
  Route docstrings note health/metrics reset and limits only change the
  web process's view.
- SchemaManager.get_schema_path resolves each search dir via
  resolve_plugin_dir (manifest id, ledmatrix-<id>) before the literal
  paths; plugins/ still before plugin-repos/. Misses cached 30s and
  logged once at DEBUG.
- install_from_url sets an existing copy aside and restores it if the
  move fails, under the per-plugin reinstall lock.
- Operation queue refuses a second pending op for a plugin and trims
  _operations with history.
- get_vegas_render_width reads display_manager.width first.
- get_logger in store/schema/health/resource/saved_repositories;
  UTF-8 reads in store_manager and state_manager.
- Docs: update_interval precedence (manifest over config) stated where
  users are told to set it in config.

* fix(web): build the limits 400 message from the field name, not an exception

CodeQL flagged str(e) flowing into the response. invalid_limit_field()
returns the offending field without raising, and limits_from_dict uses it.

ChuckandClaude Opus 5.5 0e9e2cabba fix(web): widget cache-busting, dead frontend code, and dependency pins (#656)
- Plugin-supplied widgets load as /static/plugin-widgets/...js?v=<plugin
  version>, so an update isn't hidden behind the year-long immutable cache.
- Fire-and-forget loadInstalledPlugins() calls catch the rejection it has
  already reported, so the global handler no longer adds a second toast.
- Timezone picker renders again when the General partial is re-injected.
- Remove dead code: executePluginAction's six plugin-id fallbacks and
  [DEBUG] logging, window.currentPluginConfig and every read of it, the
  file-upload JSON delete branch, unused PluginAPI / PluginInstallManager /
  PluginStateManager helpers, loadPluginWidgetsFromManifest, the stale
  install_manager.js and LEDVisibility fallbacks, error_handler.js's global
  escapeHtml, 13 unused CSS rules, and stale comments/no-op returns.
- pytz < 2027, psutil < 7 in requirements-test.txt, pytest-cov < 8.
- Pin anthropics/claude-code-action to the commit v1 resolves to.

ChuckandClaude Opus 5.5 f6c0fe55d9 fix(core): font zip cache, monotonic timers, resolver back-off, and other core/common fixes (#654)
* fix(core): font zip cache, monotonic timers, resolver back-off, and other core/common fixes

- font_manager: a .zip font URL is served as its extracted font after a
  restart (the cached-file check returned the archive first); downloads
  use requests with a 30s timeout into a temp file + os.replace.
- api_helper / sync_manager: rate-limit and heartbeat/leader timeouts use
  time.monotonic(); last_request_time and the status file's ts stay
  wall-clock. set_on_new_cycle docstring no longer claims core uses it.
- logo_helper: the placeholder uses the same scaled box as a real logo.
- permission_utils: one _sudo_bash_candidates() helper (with the sudoers
  exact-argv rationale) shared by sudo_remove_directory, which now retries
  the next bash path on a sudo refusal, and install_requirements_file.
- dynamic_team_resolver: failed/empty fetch backs off 5 min; duplicate
  INFO log and contradictory docstring example fixed.
- element_style: scale default looked up through element aliases.
- background_data_service: cache-hit callback runs outside the lock.
- config_arrays: union-aware type check (["array","null"]); stale
  dotToNested() reference removed.
- auto_update_setup: non-dict auto_update reads as off; temp result file
  unlinked when the write fails.
- exceptions: constructors copy the caller's context dict.
- logging_config: StructuredFormatter json.dumps(default=str).
- error_aggregator: removed unused export_path/export_to_file/_auto_export.
- Docstrings: validate_file_upload max_size_mb, raise_on_errors.

* fix(sync): retry the status-file rename like the other atomic writers

On Windows os.replace can fail with "Access is denied" while a scanner
briefly holds the target open; config_manager_atomic._replace already
retries that (and re-raises at once on other platforms). The sync status
writer called os.replace directly, which made
test_concurrent_writers_each_use_their_own_temp_file flaky on Windows.

ChuckandClaude Opus 5.5 6f45ff5e63 fix(display): thread-safety for deferred updates, BDF faces and follower image; one refresh default (#652)
- DisplayManager.defer_update()/process_deferred_updates(): one lock around
  every queue mutation (appends from the update thread were lost to the
  render thread's filter/slice reassignments); callables run outside it.
- FontManager and element_style no longer cache BDF freetype.Face objects
  process-wide (load_bdf_face caches them per thread); element_style's LRU
  is locked against get/move_to_end vs eviction races.
- limit_refresh_rate_hz default is one constant, DEFAULT_REFRESH_LIMIT_HZ =
  100 (the template's), for the library options, refresh_hz, the matrix
  guard, Vegas and scroll_config. Previously a missing key capped the panel
  at 90 while pacing assumed 100.
- Sync follower: the TCP thread queues the leader's scroll image; the render
  thread swaps image/array/width in between frames.
- update_display() error log rate-limited (traceback first, then once a
  minute with a count); swallowed DisplayController exceptions log at DEBUG.
- Root display_controller.py runs run.py via runpy.
- stream_manager: correct the RLock release comments; merge duplicate if.

ChuckandClaude Opus 5.5 1e62677257 fix(vegas): pause for STATIC plugins where their turn falls in the strip (#651)
The static trigger peeked at the front of StreamManager's segment buffer,
which continuous scrolling (the default) never advances -- it extends the
strip with take_next_group() -- so the same first segment was examined on
every frame. A STATIC plugin paused the scroll only if it was first, once,
at startup; otherwise it scrolled past as ordinary content. Swap mode had
the same problem for any STATIC plugin not first in its cycle.

The render pipeline now records a marker (strip column, plugin id) for
each STATIC plugin where the strip is built -- composition and every
extension -- shifts the markers when the scrolled prefix is trimmed, and
clears them on reset. The coordinator pauses when the scroll reaches the
next marker: a tuple comparison per frame instead of a lock, a plugin
lookup and a get_vegas_display_mode() call. take_next_group() no longer
renders STATIC plugins' content. The pause calls display() under the
plugin lock and is timed with the monotonic clock.

ChuckandClaude Opus 5.5 224847cebc fix(display): stop the run loop spinning when no mode has anything to show (#649)
* fix(display): stop the run loop spinning when no mode has anything to show

A mode whose display() reports nothing rotates to the next at once, with no
dwell. With every enabled mode empty (only a sports plugin in its
off-season, say) the loop went round with no sleep: on ledpi, 169% CPU and
~1,800 "No content" log lines every 10 seconds. After one full rotation of
empty passes it now pauses EMPTY_ROTATION_PAUSE (1s) per pass, servicing
plugin updates and returning early on on-demand or schedule changes; live
priority is still checked at the top of every pass, and the streak resets
as soon as any mode shows something.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(display): restart the loop if the empty-rotation pause starts on-demand; per-rotation streak

- an on-demand request serviced during the pause returned early into the
  on-demand branch, which advanced past the mode just requested; the loop
  now restarts when the pause changed the mode, on-demand state or schedule
- the streak is reset when the rotation changes (on-demand start/stop, a
  plugin enabled or disabled), so a streak from one rotation can't make
  another pause before its own modes are tried
- docstring: live content is picked up within the pause, not "at once"

ChuckandClaude Opus 5.5 aeaeaa4e94 chore: make contributor tooling work; fix drifted docs (#648)
- mypy.ini parses again (multi-line exclude and inline value comments made
  mypy reject the file); the mypy pre-commit hook is manual-only until the
  ~500 existing errors in src/ are paid down, and CONTRIBUTING says so
- .gitignore: ignore all of config/ except the templates (ytm_auth.json and
  others weren't ignored)
- .gitattributes: LF for .sh and .service
- claude-code-review: skip fork PRs, which have no secrets
- check_system_compatibility.sh: 3.13 supported, <3.10 an error
- docs/scripts drift: emulator guide, README API Metrics, route count,
  docs index, scripts README; pyflakes nits in dev scripts

ChuckandClaude Opus 5.5 76f5d8a336 fix(web): seven web UI bugs, and remove dead plugins_manager.js helpers (#647)
- Operation History: the plugin filter lists the installed plugin ids
  instead of one option, "plugins" (Object.keys of {plugins: [...]}).
- Ctrl/Cmd+S submits the active tab's first visible form with
  requestSubmit() (validation and onsubmit guards run) instead of a bare
  Event on the first form in the document; skipped inside a modal dialog
  and on tabs without a form.
- Overview "Check Updates" confirms like "Update Code", takes its button
  explicitly (no implicit global event) and shows the server's message.
  Both, and the Tools tab git pull, raise the restart-pending banner on
  restart_required.
- Tools: toolsAction and diagnostics show the server's error message;
  only a non-JSON body falls back to HTTP <status>.
- Installed list after uninstall: PluginAPI writes clear the throttler's
  GET cache, a forced loadInstalledPlugins clears it too, and the
  post-uninstall reload goes through refreshInstalledPlugins().
- Plugin widgets load from /static/plugin-widgets/ only (the other two
  paths have no route).
- Raw JSON editor escapes the parse error; slider escapes value/min/max/step.
- Removed the unreferenced array-of-objects and key-value helpers from
  plugins_manager.js, the textarea auto-resize and Ctrl+R handlers in
  app.js, and a redundant ?v= on the plugins_manager.js script tag.

ChuckandClaude Opus 5.5 7eb7a58d0c fix: web UI and src.common bugs (wifi wrong-password, plugin icon, starlark toggle, API caching, scroll/logo/font helpers) (#646)
- wifi: keep the "wrong_password:" prefix through the restore/AP fallback so
  the UI's incorrect-password prompt fires again.
- /plugins/installed returns the manifest's icon (string only).
- /starlark/apps/<id>/toggle coerces `enabled` and delegates to
  _toggle_starlark_app (disk before memory, no KeyError, "false" is false).
- /api/v3/ JSON GETs are sent Cache-Control: no-store; non-JSON keeps 5s.
- ScrollHelper.set_scrolling_image converts non-RGB input (alpha onto black);
  create/set_scrolling_image reset last_update_time like reset_scroll.
- LogoHelper backs off a failed download per path for
  MISSING_LOGO_RECHECK_SECONDS; cleared on invalidate/clear_cache.
- refresh_placeholder_timestamp saves atomically.
- FontManager.clear_cache / _clear_plugin_font_cache bump cache_generation.
- Odds manager: per-game logs to DEBUG; JSON decode error caught before
  RequestException (same cooldown).
- element_style mangled continuations; startup validator skips null plugin
  blocks and reuses the controller's discovery.
- src/common/README lists frame_timing, json_body, render_gate.

ChuckandClaude Opus 5.5 b518c51679 fix(plugin-system): load/enable failures, atomic state files, pip lock, test-double parity (#645)
- load_plugin: an on_enable() that raises unregisters the instance, so the
  next load retries instead of returning True "already loaded".
- get_plugin_info: guard plugin.get_info(); one plugin raising no longer
  breaks /api/v3/plugins/installed.
- plugin_state.json and the operation history are written with
  atomic_write_text under their lock.
- plugin_loader: module-level lock serialises pip installs across the
  parallel startup loaders.
- store_manager._install_via_download: extract dir cleanup moved to finally.
- Test doubles: draw_image() warns (DeprecationWarning; the real
  DisplayManager has none), MockDisplayManager.draw_text accepts the real
  signature's optional params, VisualTestDisplayManager logs draw errors at
  WARNING.
- Docs/comments: compatibility.py method name, PluginState.LOADED meaning,
  brittle schema count, why _report_skip_once uses setdefault.
- Remove unused PluginOperationQueue.get_active_operations().

ChuckandClaude Opus 5.5 6bc13a8934 fix(display): Vegas resumes after live priority, and six smaller runtime fixes (#644)
- Vegas: a live-priority pause was only lifted from inside run_frame(),
  which returns before that check while paused, so the ticker never came
  back until a restart. run_iteration() now resumes it (the controller
  only calls it when nothing preempts Vegas); start()/stop() clear the
  pause state. Iteration length is timed with the monotonic clock.
- Dim schedule: a per-day disabled day now updates the minute-gate cache,
  so brightness no longer flips back to dim within each minute.
- On-demand: a second request no longer overwrites the rotation resume
  index with the first request's mode.
- Render pipeline: reset() drops the prepared group and deferred queue,
  and a prefetch in flight across a reset discards its result.
- Sync: stop() removes the status file (and the controller's cleanup now
  calls it), standalone removes a stale one at startup, and writes use a
  unique mkstemp temp file.
- render_gate.swap_releases_gil() delegates to frame_timing.
- Stale docstrings/comments corrected.

ChuckandClaude Opus 5.5 bcef1957a9 fix(security): refuse unsafe plugin ids, keep secrets private, validate request bodies (#643)
* fix(security): refuse unsafe plugin ids, keep secrets private, validate bodies

- install_from_url and the registry install's manifest rename refuse a
  plugin id that is not a single safe name (no ../ out of plugins_dir).
- Uninstall and config reset refuse core config sections and ids with
  path parts; uninstall of a plugin whose directory is gone still works.
- separate_secrets checks a field's own x-secret marker before recursing,
  so object/array secrets no longer land in config.json.
- Backup restore creates missing secrets/wifi/ytm files with mode 640;
  export skips non-object manifests and no longer collides on same-second
  exports.
- SYSTEM_FONTS includes every bundled font from BUNDLED_FONTS.
- Raw config/secrets saves and validate_request_json require a JSON object.
- A blank max_dynamic_duration_seconds keeps the stored value; other values
  are validated to 30-1800 instead of raising a 500.

* fix(security): validate the id before install_plugin moves anything; claim backup names atomically

- install_plugin set aside plugins_dir / plugin_id before any id check, so
  "../x" moved a directory outside the plugins dir (the rollback moved it
  back, but only if the install path got that far)
- two exports finishing in the same second could both see a free name and
  the later os.replace destroyed the first archive; the name is now
  claimed with O_EXCL before the archive is swapped in

ChuckandClaude Opus 5.5 da5937da3d fix: six bugs found testing main on a real Pi (#641)
* fix: six bugs found testing main on a real Pi (ledpi)

- Stopping the service now runs cleanup. systemd stops ledmatrix.service
  with SIGTERM, whose default action ended Python before run()'s finally
  block, so the update worker, Vegas and the panel were never torn down.
  main() now turns SIGTERM into KeyboardInterrupt, the Ctrl-C path.
- "Now showing" no longer turns into "unknown". display_current_state was
  only written on a mode change and the web UI reads it with max_age=120,
  so a live game or a single plugin on screen for longer read as unknown.
  It is republished every 30 s while unchanged.
- Switching Vegas on in the web UI works when it was off at startup. The
  coordinator was only created at startup; the config watcher now flags it
  and the render thread creates it.
- configure_web_sudo.sh finds reboot and poweroff in /usr/sbin. Run as the
  web user it could not, silently dropped their rules and still said it
  granted them, so the web UI's Reboot/Shutdown stopped working.
- check_system_compatibility.sh reports installed packages as installed.
  `dpkg -l | grep -q` under pipefail failed when grep exited early.
- A network failure fetching GitHub repo info logs a WARNING, not ERROR.

* docs(changelog): fixes found testing on a Pi

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* test: run the Linux-only script tests correctly

The sbin-lookup test set PATH=/nonexistent and then could not find bash
itself; call it by absolute path. The dpkg-query stub read $4, but the
package name is the third (last) argument. Both now pass on a Pi.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(display): cover the follower, long-render and startup cases

Review follow-ups on the ledpi fixes:
- The pending Vegas start is applied before the sync-follower branch too
  (_apply_pending_vegas_init), which skips _is_vegas_mode_active() while a
  follower is connected but needs the coordinator for the leader's image.
- _service_pending_changes(), which runs inside Vegas iterations and long
  screens, republishes a stale display_current_state as well; the main
  loop alone could be away for a 240 s Vegas iteration.
- The SIGTERM handler is installed after DisplayController() is built, so a
  stop during parallel plugin loading keeps the default immediate exit.

ChuckandClaude Opus 5.5 865d62f67b feat(display): compensate for the panel's scan order while scrolling (#634)
A 1:N-scan HUB75 panel lights the two rows either side of its middle at opposite ends of each refresh, so a scroll at one pixel per refresh shows a 1px step across the middle of every panel. While something scrolls at one frame per refresh, DisplayManager now shows the half whose seam row lights first one refresh behind the other (src/scan_order.py), which lines the two up again. Only for layouts whose row order is known; display.scan_order_compensation "off" disables it. Confirmed on hdpi before and after.

A stall watchdog logs the stacks behind any scroll held up for 250 ms or more (LEDMATRIX_STALL_WATCHDOG_MS lowers that). See docs/SCROLL_PERFORMANCE.md, "Soaking a rig".

ChuckandClaude Opus 5.5 b9416ef803 fix(display): Vegas teardown and 240s default; remove dead Vegas buffer code (#637)
* fix(display): tear down Vegas mode on controller cleanup

DisplayController.cleanup() never called VegasModeCoordinator.cleanup(),
so the Vegas teardown (stop, pipeline/stream reset, adapter cache drop)
was unreachable. Call it before the display manager is cleaned up, and
skip it when Vegas was never created.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(vegas): default max_cycle_duration to the documented 240s

The template, the web UI help, CONFIG_REFERENCE and the controller all
say 240, but the code defaulted to 600 in two places, so a config
without the key ran Vegas iterations 2.5x longer than documented.

from_config now falls back to the dataclass field defaults instead of
repeating each one, so the two copies can no longer drift, and the
controller's follower scroll-speed default reads VegasModeConfig's.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(display): let run.py -d show display_manager's DEBUG output

display_manager pinned its logger to INFO at import, overriding the root
level, so debug mode never showed its DEBUG lines. Use get_logger() from
src.logging_config like the rest of the core and leave the level to the
logging setup.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(display): run each startup validation check once

StartupValidator.validate_all() ran twice at boot, before and after the
plugin manager was created, so every config, cache, display and
systemd-unit warning was logged twice. The second pass now runs only the
plugin checks. Drop the commented-out raise_on_errors line.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(vegas): one INFO line per plugin-list refresh

StreamManager logged "=" * 60 banners and a line per plugin (INCLUDED,
SKIPPED, FETCHING CONTENT, SEGMENT CREATED) at INFO on every refresh and
fetch, i.e. at each cycle start and every 30s. Log one INFO summary of
the rotation per refresh and move the per-plugin detail, the weighting
breakdown and "no content this cycle" to DEBUG (the adapter still warns
when every content path fails).

Also drop the check/cross marks from the controller's log messages.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(vegas): drop the per-iteration static-mode plugin scan

run_iteration() rebuilt _static_mode_plugins on every iteration, asking
every plugin for its display mode and logging the set at INFO, but
nothing ever read it: static pauses are triggered by
_check_static_plugin_trigger() from the next segment. Delete it, the
coordinator's get_ordered_plugins() that only it used, and the
write-only _static_pause_plugin / _static_pause_start.

* fix(vegas): remove the staging buffer that was never filled

StreamManager and RenderPipeline carried a double-buffer design that
nothing used: _staging_buffer was only ever cleared or swapped, so
swap_buffers() never did anything and should_recompose()'s
staging_count > 0 branch was dead, and _active_scroll_image,
_staging_scroll_image, _is_rendering, _last_frame_time and
_frame_interval were written but never read. Delete the machinery and
rewrite the docstrings around what actually carries updates:
_pending_updates, consumed by process_updates() in swap mode and
invalidate_pending_updates() in continuous mode.

should_recompose() no longer builds a buffer-status dict every frame.

* refactor(display): tidy the display controller without changing behaviour

- Import VegasModeCoordinator locally instead of through module globals
  (there is no circular import to avoid).
- Drop hasattr() checks on attributes PluginManager.__init__ always sets
  (plugin_executor, plugin_last_update, get_plugin_lock,
  run_scheduled_updates*, stop_update_worker) and the dead "older
  manager" fallbacks; keep the health_tracker None checks, now via
  _health_tracker().
- Extract _display_once() for the per-frame display call both render
  loops copied, _advance_on_demand() for the two on-demand rotations,
  _reset_on_demand_fields() for the error and clear paths, and
  _timezone() / _in_window() for the two schedule checks.
- Remove always-true conditions and the unreachable non-plugin else
  branch in run(), and read _was_display_active / _last_published_mode /
  vegas_coordinator directly now that __init__ declares them.
- Declare the follower render state in __init__, name its tuning
  constants, add _follower_sign(), and share the 90/s sync send
  interval with the render pipeline (SYNC_SEND_INTERVAL).
- Delete history narration and the "Opt #N" labels, fix the comment
  that called _scroll_speed constant (hot reload updates it), and drop
  a startup timing log that measured nothing.
- render_pipeline / plugin_adapter: read display_manager.width/height
  as the properties they are, drop an empty TYPE_CHECKING block, an
  aliased threading import and a duplicated `if result and
  self.sync_manager:`.

* refactor(display): trim dead code from display_manager

- Add _new_canvas() for the image/draw/fontmode="1" setup that was
  copied six times.
- Call resolve_double_sided() and compose_pixel_mapper_config() directly
  instead of through a module alias and a passthrough method, and replace
  the comment that said the passthrough read class attributes.
- Delete the unused _initialized flag and _ORIENTATION_ROTATE_DEGREES
  alias (no core or monorepo reader; tests stop resetting the flag), the
  test pattern's unreachable no-matrix branch (it only runs once the
  matrix exists), `del old_image  # help GC` (a no-op on a local), a
  duplicated early return in process_deferred_updates, and stale
  comments.

* refactor(vegas): remove unread fields and test-only helpers, fix docstrings

- ContentSegment: drop total_width, fetched_at, is_stale, image_count and
  is_static, none of which is read.
- StreamManager: drop _current_index (never advanced) and the test-only
  get_all_content_for_composition() and has_pending_updates();
  VegasModeConfig: drop the test-only is_plugin_included().
- geometry.find_blank_cut() has had no production caller since the crop
  moved to item boundaries; delete it and its tests.
- PluginAdapter: the _finalize docstring described separator_width
  between every image, and _crop_to_budget's said cuts snap to the
  nearest blank column; both now describe what the code does.
- Coordinator: the static-pause interrupt log no longer blames follower
  mode for every interrupt, and set_update_callback names the callback
  the controller actually wires.

* refactor(scroll): correct ScrollHelper comments and drop dead branches

- Four comments said the strip always starts with display_width of
  blank; it does only when lead_gap is None (Vegas passes its own).
- Delete the "Width calculation mismatch" warning: the image is created
  at the calculated width, so the two can never differ.
- Remove the two scroll_delay <= 0 fallbacks (which disagreed with each
  other): set_scroll_delay clamps it to at least 0.001 and nothing in
  core or the plugin monorepo assigns it directly.
- Trim the scipy history from the blend docstring.

* fix(display): log set_scrolling_state only when it changes

Vegas and scrolling plugins set the scrolling state every frame, so once
display_manager's DEBUG output became visible in debug mode it printed
"Scrolling state set to: True" about 120 times a second. Log only when
the value differs from the previous one; the state, activity timestamp
and frame hold still update on every call.

ChuckandClaude Opus 5.5 f6afbdbb15 fix(web): Cache/Logs error mix-up, store errors, tab fallbacks; remove ~2.5k lines of dead JS (#639)
* fix(web): keep Cache and Logs helpers out of each other's way

Both partials declared top-level showError and escapeHtml. Their scripts
run at global scope after every HTMX swap, so whichever tab was opened
last owned window.showError, and a Cache failure after visiting Logs
rendered into the Logs panel (and the other way round). Each script is
now an IIFE; Cache still exports deleteCacheFile for its row buttons.

* fix(web): make the HTMX-failure fallbacks for tab panels actually run

- The "HTMX never loaded" fallback read appElement.__x.$data, which is
  Alpine 2. The page ships Alpine 3, so the check was always false and
  the Overview never loaded without HTMX. It now reads Alpine.$data().
- The Overview and WiFi panels used hx-on::htmx:response-error, which
  htmx expands to "htmx:htmx:response-error", an event that never fires.
- loadTabContent sent requests with <body> as the source, so htmx fired
  its events on <body> and no panel's hx-on handler ran at all. The
  panel is now the source. htmx also resolves its promise on a 4xx/5xx,
  and the panel was stamped data-loaded anyway, leaving a skeleton that
  never retried; it is now stamped only when no responseError fired.

loadPluginsDirect, loadOverviewDirect and loadWifiDirect are merged into
one window.loadPartialDirect(id, url), which also runs the partial's
inline scripts before Alpine sees the markup (as htmx-config.js does on
htmx:afterSwap). The ~10 s "htmx never arrived" path in loadTabContent
uses it for every tab instead of four hard-coded ones.

* fix(web): store and registry failures no longer wipe the Plugin Manager

showError replaced the whole #plugins-content with an error message, so
one failed store search, custom-registry install or saved-repository
call took the installed list, the store and every control with it, with
no way back short of reloading the tab. Those failures are now error
notifications. The full-panel message is kept only for a first load of
the installed list that failed (nothing to show yet); a failed refresh
of an already-rendered list is a notification too. showSuccess's
fallback branch, which wrote the message into innerHTML unescaped, is
gone: showNotification always exists.

The "Please try refreshing your browser" hint tested for the text
"Failed to Fetch", which no browser produces (Chrome says "Failed to
fetch", Firefox "NetworkError..."), so it never appeared. It now keys on
the failure itself: a TypeError from fetch(), or PluginAPI's
NETWORK_ERROR wrapper around one.

* fix(web): escape plugin action and install output on every path

executePluginAction escaped data.message and data.output when an action
failed but put data.message straight into innerHTML when it succeeded,
and set the OAuth step-2 button's innerHTML from the manifest's
step2_button_text. Plugin actions run plugin code, so that is plugin- or
server-controlled markup in the page. Both paths now escape, and the
button label is set with textContent.

The same pattern sat in the install-from-GitHub-URL status lines
(plugin_id, the server's message, and error.message, which can echo a
repository URL) and the custom-registry load error; those are escaped
too.

* fix(web): file-upload widget owns the image list and schedule editor

plugins_manager.js loads after the widget bundle, so its older copies of
deleteUploadedFile, updateImageList, hideUploadProgress, formatDate,
openImageSchedule, toggleImageScheduleEnabled, updateImageSchedule{Mode,
Time,Day} and updateCheckboxGroupData replaced the widget's. They are
deleted; the widget files are the only definitions.

Before switching over, the two sets were diffed and fixed so nothing
regresses:

- The old copy labelled the schedule/delete buttons for screen readers
  and lazy-loaded thumbnails; the widget now does both.
- The schedule button did nothing on a card rendered by
  plugin_config.html whenever the image id is a UUID (every upload): the
  template turns "-" into "_" in the editor's id, and neither JS copy
  did. Both now use the template's rule.
- The widget's "keep the open editor open" copied the editor's innerHTML
  into the new list. That dropped its event listeners and showed the old
  values, so after the first change the editor looked live but ignored
  input. A schedule edit now saves to the hidden input and updates the
  card's summary in place without re-rendering the list; a list re-render
  (upload, delete) rebuilds an open editor from the data. Editor controls
  are routed by one delegated change listener, so there are no
  per-element listeners to lose.
- The old deleteUploadedFile had a JSON branch that removed a
  #file_<id> element and skipped the re-render. No template or script
  renders such an element, and JSON uploads are listed through
  updateImageList like images, so re-rendering (the widget's behaviour) is
  the consistent one; the branch was not carried over.
- The template always renders the summary line (".image-schedule-summary",
  "Always shown" when unscheduled) so an edit has a line to update.

The inline-handler test evaluated plugins_manager.js's updateImageList;
test_file_upload_widget.js now covers the widget's list and editor.

* refactor(web): delete the unused handleCredentialsUpload

Its last caller went when plugin_config.html switched credential uploads
to the file-upload widget's handleSingleFileSelect. Nothing in the web
UI, the tests or the plugin monorepo references it.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* refactor(web): delete dead and shadowed front-end code

Nothing calls any of these (checked across web_interface/, test/ and the
ledmatrix-plugins monorepo, including hx-*/x-*/onclick attributes):

- app-shell.js: the Alpine methods refreshPlugins (it called a
  nonexistent this.searchPluginStore), loadPluginConfig,
  savePluginConfig, getSchemaPropertyType, escapeCssSelector,
  formatCommitInfo and formatDateInfo, and the top-level copies of
  savePluginConfig, getSchemaPropertyType, escapeCssSelector,
  formatCommitInfo, formatDateInfo and togglePluginFromTab. Plugin config
  forms save through hx-post in plugin_config.html.
- window.reconnectSSE (app-shell.js); window.updateArrayTableAddButtonState
  (array-table.js).
- toggleNestedSection, defined twice (app-shell.js and
  plugins_manager.js) and called from nowhere.
- plugins_manager.js: the window.initializePlugins wrapper around an
  IIFE-local origInit that was always undefined, and __pluginDomReady,
  which was written but never read.
- display.html's fixInvalidNumberInputs fallback: app-shell.js defines it
  before any partial loads.
- base.html's window.loadCodeMirror and the two CodeMirror stylesheet
  preloads, and the .CodeMirror rules in plugins.html. The raw JSON
  editor is a plain textarea.

Also deleted: app-shell.js definitions that a later script always
replaced, so they never ran: executePluginAction (plugins_manager.js
assigns its own), uninstallPlugin and its pollUninstallOperation
(plugins_manager.js), and updateAllPlugins (install_manager.js).

vendor/codemirror stays: test/test_web_smoke.py still requests
codemirror.min.js as a sample static asset.

* refactor(web): call showNotification without checking it exists

app-shell.js defines window.showNotification (a stand-in that queues
until the notification widget loads) and base.html runs it, deferred,
before every other script that notifies: app.js, the utilities, the
widget bundle, plugins_manager.js, and all partials, which HTMX loads
after the page. The 81 `typeof showNotification === 'function'` /
`!== 'undefined'` checks, the `window.showNotification || console.log`
and `|| alert` fallbacks, and their else branches (alert(), console
output, and schedule.html's own hand-built toast) could never take the
fallback path. They are removed, as is fonts.html's second copy of the
queueing stand-in.

The stand-in in app-shell.js keeps its guard (it must not replace the
widget's implementation if load order ever changes), and BaseWidget's
public notify()/getNotificationFunction() keep their shape for widgets
that plugins ship.

* refactor(web): one HTML escaper, window.LEDEscape

About 30 files each carried their own escapeHtml / escapeAttr / escHtml /
_esc / escapeJs. They disagreed: several (notification.js, display.html's
escapeHtml, operation_history.html, the app() stub) did not escape
quotes, google-calendar-picker.js and tools.html's escHtml left ' alone,
and some turned 0 into ''. Most were fine only because the quote-safe
widget copies were preferred at runtime.

window.LEDEscape now lives at the top of app-early.js, a blocking script
in <head>, so it exists before any other script runs:

  html(v)          & < > " ' as entities, null/undefined as ''
  attr(v)          the same, for call sites that want to say "attribute"
  jsStringAttr(v)  a JS string literal safe inside an inline handler

Every former copy is now a one-line name for it (kept so call sites do
not change), widgets included, with no fallback. plugins_manager.js
loses its four escapeJs wrappers (callers use jsStringAttr), the
duplicate escapeAttr and escapeHtml inside renderInstalledCards and
renderCustomRegistryPlugins, and the window.escapeHtml /
window.escapeAttribute exports, which nothing read.
addArrayObjectItem's fallback markup (with a sixth hand-written escape
chain) is gone too: window.renderArrayObjectItem is defined earlier in
the same file, so the fallback could not run. The unused escapeHtml
methods on the Alpine app (app-early.js stub and app-shell.js) are
deleted.

test_html_escaping.js now runs LEDEscape and every remaining name for it,
and fails if a hand-rolled escaper reappears anywhere in web_interface/.
Suites that evaluate slices of plugins_manager.js or widget files load
LEDEscape from app-early.js through test/js/led_escape.js.

* fix(web): stop htmx re-running partial scripts after every tab load

htmx-config.js runs each swapped-in <script> itself on htmx:afterSwap
and meant to turn htmx's own script handling off with
htmx.config.allowScriptTags = false. It did that once, while setting up,
but base.html loads htmx with a dynamic <script>, so htmx was not defined
yet and the setting never applied. On every tab load htmx then tried to
run each script again in its settle phase, found it already replaced
(no parent node) and threw "Cannot read properties of null (reading
'insertBefore')" into the console, which also skipped the rest of that
swap's settle tasks.

The setting is now applied in the afterSwap handler, which always runs
after htmx exists and before htmx settles the same swap.

* fix(web): show "--" for a system stat the server could not read

The stats stream and /system/status now send null for a metric they
cannot read (cpu_temp off a Pi, for one) instead of 0. updateSystemStats
built the header and Overview text as value + unit, so a null showed as
"null°C". CPU, memory and temperature, in the header and on the
Overview, now render "--" plus the unit for null or a missing field --
the same placeholder the page starts with, and what tools.html already
shows.

* refactor(web): one Alpine accessor and one plugin-list signal

window.getApp() (app-early.js) returns the root <body x-data="app()">
component through Alpine's public Alpine.$data, or null before Alpine
has initialised it. It replaces the private el._x_dataStack[0] reads in
app.js, app-early.js, app-shell.js, settings-search.js, overview.html and
plugins_manager.js, the three local getAppComponent/appData/getAppData
copies, and the Alpine 2 el.__x.$data fallbacks, which Alpine 3 never
provides.

Publishing the installed-plugin list: one load set window.installedPlugins
and dispatched pluginsUpdated twice (loadInstalledPlugins, then
renderInstalledPlugins), then wrote into the Alpine component through
_x_dataStack[0] and called its updatePluginTabs() directly, and
app-early.js's global listener set window.installedPlugins a third time
and called updatePluginTabs() again. Now renderInstalledPlugins is the
one publisher: it sets window.installedPlugins and dispatches
pluginsUpdated once, and the full app()'s listener (app-shell.js) is the
receiver. The app-early.js listener only builds the tab row while the app
is not the full implementation yet. The "grid not loaded yet" case is a
normal state (Plugin Manager tab not opened), so it logs through
pluginLog instead of console.warn.

updatePluginTabs had a "Debounce" comment and clearTimeout over a timer
nothing ever set, and two identical branches; it now just calls
_doUpdatePluginTabs (app-early.js detects the full implementation by
that name in its source, which the new comment says).

app()'s unused baseComponent lookup is removed.

* fix(web): reload the plugin list after installs and failed toggles

Several callers refreshed the installed list with

    if (typeof loadInstalledPlugins === 'function') loadInstalledPlugins();
    else if (typeof window.loadInstalledPlugins === 'function') ...

but loadInstalledPlugins is local to the plugin-manager IIFE and
window.loadInstalledPlugins is never defined, so from outside that IIFE
both tests were false and nothing reloaded:

- A failed plugin toggle left the switch drawn in the new state while
  the data said the old one. It now re-renders from the reverted data.
  The optimistic in-place edit also has to forget the grid's
  last-rendered markup, or setGridHtmlIfChanged sees identical HTML and
  skips the revert. A successful toggle still keeps the switch (and
  focus) as drawn.
- Installing from a GitHub URL (the early handleGitHubPluginInstall),
  installing or uploading a Starlark app, and toggling a Starlark app on
  its config tab never refreshed the list, so the new app had no tab or
  Installed badge until the page was reloaded. They now force a reload
  through window.pluginManager.loadInstalledPlugins(true), and the
  Starlark grid redraws when that finishes instead of after a fixed
  500 ms.
- The Starlark uninstall inside the IIFE reloaded from the 3 s cache,
  which could still hold the app; it now forces a reload.

* refactor(web): route debug output through debugLog

base.html defines window.debugLog, gated on localStorage.pluginDebug.
plugins_manager.js read the same key twice more into its own flags
(_PLUGIN_DEBUG_EARLY, and PLUGIN_DEBUG behind a pluginLog() wrapper), and
api_client.js's RequestThrottler had a separate `debug` property with a
setDebug() that nothing called. All of it now goes through debugLog. The
"functions defined" dumps with their ✓ lines, and two per-plugin
"enabled=" loops that ran on every render, are dropped; "[PLUGINS STUB]"
labels on code that has not been a stub for a long time read
"[PLUGINS]".

Ungated console.log calls that announced normal events on every page
load or action (settings search and tooltips registering, every toast
repeated to the console, the schedule pickers initialising, widget
registry unregister/clear) go through debugLog too. What remains on
console.log is the widget registry's on-demand LEDMatrixWidgets.debug()
dump and BaseWidget.notify's no-notifier fallback.

* refactor(web): drop waits and guards that could never fire

- handlePluginAction polled up to 10 x 50 ms for window.togglePlugin,
  configurePlugin, updatePlugin and uninstallPlugin before calling them.
  All four are defined when the scripts load, before any card can be
  clicked, so the poll always succeeded at once; it now calls them.
  The long thinking-aloud comment over the toggle state is replaced by
  two lines on why the stored state, not the checkbox, decides.
- initializePlugins checked typeof on setupGitHubInstallHandlers and
  applyStoreFiltersAndSort, function declarations in the same IIFE, and
  wrapped window.checkGitHubAuthStatus(), which returns a promise with
  its own .catch, in try/catch.
- searchPluginStore wrapped each "#store-count" update (a getElementById
  and an innerHTML assignment) in try/catch four times; one
  setStoreCount() helper does it. The store's post-render re-attach of
  the GitHub token handler dropped its try/catch and existence checks
  for the same reason.
- The load-time fallback outside the IIFE tested typeof
  initializePluginPageWhenReady, which is IIFE-local and so always
  undefined there; it calls window.initPluginsPage directly.

* refactor(web): delete two unused plugin-manager helpers

stopOnDemand (IIFE-local; the page's stop button calls window.stopOnDemand
from app-shell.js) and debounce had no callers.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* refactor(web): document the plugin-config handlers templates call

validatePluginConfigForm, handleConfigSave, handleToggleResponse,
handlePluginUpdate and refreshPluginConfig each get a JSDoc naming the
attribute in partials/plugin_config.html that calls it and what the
return value means (only validatePluginConfigForm's matters: false
cancels the submit).

- The `if (!window.__pluginConfigHandlersInitialized)` wrapper is gone:
  app-shell.js runs once per page, so it was never false. The block is
  dedented one level; `git diff -w` shows the real change.
- The three handlers read xhr.responseJSON first. XMLHttpRequest has no
  such property (it is jQuery's), so that branch never ran; one
  xhrJson(xhr) helper parses responseText for all of them, with the same
  fallbacks as before.
- runPluginOnDemand and stopOnDemand checked that plugins_manager.js's
  openOnDemandModal/requestOnDemandStop exist; plugins_manager.js is on
  every page, so they call them.
- fixInvalidNumberInputs had a stray "Notification helper function"
  comment on top of its own; a leftover "section toggle ... duplicate
  definition removed" note is gone.

* fix(web): one toast per save, and a failed durations save says so

app.js's global htmx:afterRequest listener showed the server's message
for every htmx request, and every form and button that posts through
htmx (plugin config save/toggle/update, Display, Durations, General,
Schedule, Dim schedule, the Overview actions) also reports its own result
from hx-on after-request. Each save showed two toasts. The global
listener now stays quiet for a request whose element, or its form, has
its own after-request handler.

That exposed the Rotation & Durations form's handler, which read
xhr.responseJSON: XMLHttpRequest has no such property, so it always said
"Durations saved" in green, even when the save failed (the global toast
had been the only place the error showed). display.html already had a
correct version (2xx only counts as saved; the server's message wins;
its status may refine success but never overturn failure). That is now
window.showSaveResult(xhr, savedText, failedText) in app.js, used by the
Display, Durations and General forms; General's inline copy of the same
logic is gone.

* docs(web): file headers and comments that say what the code does now

- plugins_manager.js, app-shell.js, app.js and app-early.js open with a
  header: what the file owns, how base.html loads it and in what order
  relative to the others, and the globals it defines. app-early.js's
  app() stub also says why it exists and that, with app-shell.js now
  loaded before Alpine, it does not run in practice.
- base.html's note on plugins_manager.js said it must load last to win
  over same-named functions in app.js/app-shell.js; there are none left,
  so it now gives the real reason (it uses everything loaded before it).
- Change-narration and "already defined at the top, no need to redefine"
  notes are gone or rewritten as present-tense reasons; comments that
  were wrong are fixed ("Toggle password visibility" over the function
  that opens the token panel, "Insert before the closing </nav>" over an
  appendChild, "(from v2)", the export note that still listed
  escapeHtml). About forty comments that restated the line below them
  are removed, and a second window.currentPluginConfig = null outside the
  IIFE is dropped (the IIFE sets it).
- The file-upload, checkbox-group and custom-feeds widgets' render()
  stubs say plainly that the widget is rendered server-side, instead of
  "for now" / "placeholder for future client-side rendering".

test_plugin_action_delegation.js sliced the source up to one of the
removed notes; it now ends the slice at the next section header.

* fix(web): keep the escapeHtml/escapeAttribute globals for plugin pages

6da77363 removed window.escapeHtml and window.escapeAttribute because nothing in core or the plugin monorepo read them. Plugin web UIs served through serve_plugin_web_ui and third-party plugin pages may still call them, so they come back as aliases of window.LEDEscape.html and .attr, defined in app-early.js before any other script runs. test_html_escaping.js checks the aliases exist.

* fix(web): clear Codacy findings in the escaper, app shell and upload widget

- LEDEscape looks entities up in a Map instead of indexing an object.
- showNotification is declared as a global for app-shell.js.
- openImageSchedule checks the index is a non-negative integer and reads
  the image with Array.prototype.at.
- The schedule editor calls escapeHtml directly and documents why its
  innerHTML template is safe: every value is escaped or constrained.
  The remaining rule hits are suppressed on that line with the reason.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(web): build the image schedule editor with DOM calls

Codacy does not honour inline suppressions, and the editor's innerHTML
template kept tripping its XSS rules even though every value was escaped.
The editor is now built with a small element helper (createElement and
setAttribute), so no value is ever parsed as HTML, and the file's own
escapeHtml goes away.

Also for Codacy:
- LEDEscape.attr is its own function rather than a second name for html.
- The tab loader records a failed load on the panel (data-load-failed)
  from a named handler, instead of a closure over a local flag.

The fake DOM in test_file_upload_widget.js gains append/replaceChildren,
its hostile-id check now asserts the id arrives as attribute data with no
innerHTML anywhere in the editor, and test_html_escaping.js drops the
file-upload.js escaper it no longer has.

* refactor(web): schedule editor helpers as plain functions

Codacy's lint flags arrow functions held in local constants and a forEach

declarations (displayStyle, scheduleModeOption, scheduleRangeTime,
scheduleDayTime, scheduleDayRow) taking what they need as arguments, and
the element helper loops with for...of. htmx is declared as a global in
app-shell.js. Output is unchanged; test_file_upload_widget.js passes.

ChuckandClaude Opus 5.5 3a81f38f09 fix(web): uniqueItems saves, /health count, Vegas order wipe; one list-repair helper (#638)
* fix(web): drop repeats from uniqueItems lists before validating a plugin save

dedup_unique_arrays lost its only caller in #330, so submitting a value a
uniqueItems list already holds (a stock symbol saved once and posted again)
failed the whole save with a validation error. _prepare_plugin_config_for_save
runs it again just before validation, which covers both POST /plugins/config
and plugin sections posted to /config/main.

* fix(web): /health counts the discovered plugins and logs the checks it fails

The plugin check counted plugin_manager.get_available_plugins(), which
PluginManager does not have, behind a hasattr guard that made plugin_count 0
on every device. It now counts the discovered manifests, discovering first
when nothing has been scanned yet.

The config, plugin and hardware checks answered "see logs for details"
without logging anything. Each now logs a warning with the traceback.

* fix(web): store refresh no longer claims a commit-metadata refresh

POST /plugins/store/refresh read fetch_commit_info (or fetch_latest_versions)
only to append "(with refreshed commit metadata from GitHub)" to its message.
It never fetched any: the route re-downloads the registry and nothing else.
search_plugins takes the flag, but it reads commit info through its cache,
so passing it on would not refresh anything either. The flag is ignored now
and the message says what happened.

* fix(web): refuse a malformed Vegas plugin order instead of clearing it

A vegas_plugin_order or vegas_excluded_plugins value that was not JSON, or
not a list, was stored as [] and the save answered 200, so a bad value wiped
the saved order or exclusions. Both now answer 400 and save nothing, the way
plugin_rotation_order already did; the three share one parser. A list that
holds anything but plugin-id strings is refused as well.

* fix(web): per-plugin health and metrics read the display service's latest

GET /plugins/health/<id> and /plugins/metrics/<id> called get_health_summary
and get_metrics_summary without force_reload, so they answered with whatever
the web process read first and kept in memory, while the display service kept
writing newer state. They now pass force_reload=True, as the list routes do.

* fix(web): plugin config reset saves through the shared atomic save

POST /plugins/config/reset called config_manager.save_config directly, so it
took no backup, and a failed write escaped as an unhandled exception. It then
handed on_config_change the raw stored section, not the prepared config a
loaded plugin runs with. It now saves through _save_config_atomic with a
backup, answers CONFIG_SAVE_FAILED when that fails, and notifies with
_prepared_plugin_config, as POST /plugins/config does.

POST /plugins/toggle carried its own copy of _save_config_atomic's
save_config_atomic-or-save_config fallback; it calls the shared helper now.

* fix(web): one reading and one "unavailable" for each system metric

system_metrics.collect_system_metrics() promised None for a metric it could
not read, but returned cpu_temp as 0 off a Pi, and the whole no-psutil
fallback as zeros. GET /system/status measured the same numbers a second time
with its own code, and answered None there. Now both come from
collect_system_metrics(), and "unavailable" is None everywhere.

/system/status keeps its 0.1s CPU sample and its 10s cache, and gains
nothing it did not already send. Two differences: without psutil it answers
200 with null metrics instead of 503, and a disk it cannot stat is null
instead of a 500.

* fix(web): /display/current sends the snapshot as-is and logs a failed read

GET /display/current PIL-decoded the preview snapshot and re-encoded it before
base64-ing it, spending CPU on the Pi to send the same picture, and dropped
any failure with `except Exception: pass`. The /stream/display SSE stream
already passed the PNG's bytes straight through.

Both now read through web_interface/display_preview.py and answer with the
same payload. A missing snapshot is still a null image; any other read
failure is logged as a warning. /health reads the snapshot path from the same
module.

* refactor(web): one helper puts a submitted plugin config's lists back

The plugin-config save turned position-keyed dicts ({"0": ..., "1": ...})
back into lists in five copies: four in the form path's
fix_array_structures (whose prefix branches never ran, since no caller
passed one), and _fix_json_arrays on the JSON path. It then force-fixed
the news plugin's feeds.custom_feeds by name, in case the generic pass had
missed it. src/web_interface/config_arrays.coerce_array_shapes now does it
for both paths, custom_feeds included. ensure_array_defaults duplicated
_fix_none_arrays and is gone.

In the same function: the union-type re-checks that the null handling
above them made unreachable, the "(temporary)" random_seed debug log, and
a commented-out log line are removed. A failed validation is logged once
as a warning, not four ERROR lines and a WARNING.

Element types are left to normalize_config_values, which already converted
them for both paths. One difference: the form path no longer adds an empty
{} for a nested object the post left out that has no defaults.

* refactor(web): import at module top and log through the module logger

The web_interface.cache imports in config.py and fonts.py were wrapped in
`except ImportError` fallbacks. It is an in-repo module that imports nothing
from the project, so it cannot fail to import; it is imported once at module
top, as system.py now does. cache.py's docstring said blueprints import it
lazily "to avoid circular imports"; it now says why that is unnecessary.

Five logging.error calls in the dim-schedule GET and three logging.warning
calls in plugins.py went to the root logger; they use the module logger.
Function-local re-imports of json, os, shutil, logging and Path, all
already imported by the module, are gone. The `import os` inside two except
blocks of save_plugin_config also made os a local name for the whole function.

execute_plugin_action's step-1 handler gets a comment saying why it stays:
it looks like a copy of the blueprint handler, but without it a
TimeoutExpired from the plugin's script would reach the route's own
`except subprocess.TimeoutExpired` and be answered as a 408.

* refactor(web): app.py loses dead CSRF and reconciliation state, comments fixed

- csrf was always None, so `if csrf: csrf.exempt(...)` never ran, and its
  note that the api_v3 blueprint "is exempted above" named an exemption that
  does not exist. Both are gone; the reason there is no CSRF protection stays,
  shortened.
- The SSE rate-limit comment called the default "tight" at 20 per minute. The
  default is 1000 per minute and the streams' 200 is the tighter one; the
  comment now says so. The limits are unchanged.
- _reconciliation_done was written and never read. The docstring that
  explains why reconciliation runs once keeps its reason, in the present
  tense.
- Removed: a dangling "import cache functions" comment with no import under
  it, a "security check ... within project_root" label on an existence check,
  the "(simplified version)" narration, and the note that no redirect route is
  needed. The preview loop's sleep comment no longer mentions a PIL encode
  that the loop does not do.

* docs(web): api_v3 comments name the package __init__, not a _common module

Every route module's docstring said the shared blueprint comes "from
._common", a module the package split never created; they name the
package __init__. The PROJECT_ROOT comment described the path from
_common.py; it now describes this package and keeps the incident it
guards against. The "(corrected) in this commit" note in
resolve_pull_command and the /health comment the split's mechanical
time -> _pkg.time rewrite garbled ("Stamp the start _pkg.time") read
correctly again.

* refactor(web): drop hasattr checks for attributes PluginManager always has

PluginManager.__init__ sets health_tracker and resource_monitor (to None
until they are configured), so the seven
hasattr(api_v3.plugin_manager, ...) guards in the health, metrics and limits
routes were always true. The falsy checks that do the work stay.

* refactor(web): pages_v3 dispatches partials from a dict with one error handler

load_partial chose a loader through a fourteen-branch if/elif, and thirteen
of the loaders then wrapped themselves in the same try/except, logging
"Error loading partial" without saying which. The route now looks the name up
in _PARTIAL_LOADERS and has the one handler, which logs the partial's name.
The loaders just render. _load_tools_partial keeps its own messages. The
search index's _partial_html already catches a loader that raises.

serve_plugin_web_ui repeated _plugin_dir_for inline (containment plus the
ledmatrix- prefix fallback); it calls it now. Also removed: the unused
markupsafe.escape import, function-local json/Path re-imports, and unused
exception bindings.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* refactor(web): remove unused imports, locals and a try that cannot fail

- get_error_aggregator was imported by the api_v3 package and used by no
  one; seven names config.py imported, and Path in misc.py and logging in
  plugins.py, likewise.
- branch_info in install_plugin was built and never logged; test_config in
  /health was bound and never read (the load_config call is the check).
- An f-string with no placeholders in the asset upload route.
- _installed_plugin_ids wrapped list(manifests.keys()) in try/except;
  _discovered_plugin_manifests always returns a dict.

* refactor(web): start.py logs its startup lines and drops unreachable branches

The startup banner went to stdout with print(); it goes through a logger
now, which the app import has already configured, so it reaches the journal
with a level and timestamp like every other line. The "no addresses" branch
is gone: get_local_ips() always returns at least "localhost".

The except around app.run re-raised "only if it's not a client
disconnection error" from inside the branch that had just established it
was one, so that raise could not run. It is one check now, on a named
tuple of the errnos, which the werkzeug log filter uses too. The comment
on threaded=True counts three SSE endpoints, which is how many there are.
Trailing whitespace is stripped.

* refactor(web): save_main_config names its General fields once

The General tab's field names were listed twice, once to detect a General
form post and again, with four more, to keep the remaining-keys merge from
storing them as top-level keys. GENERAL_FIELDS and _MAPPED_TOP_LEVEL_FIELDS
hold them now, and the four per-section skip checks are one set.

The comment on that merge said plugin configs are handled "here too", and
"(including plugin keys)". Plugin sections are handled and removed from the
body before it runs; the comment says so.

* refactor(web): plugin directories come from the plugin manager only

Six lookups fell back to PROJECT_ROOT/plugins/<id> when there was no plugin
manager: GET /plugins/config's of-the-day data, POST /plugins/action, the
plugin static-file route, the calendar credentials upload and the calendar
OAuth routes. The loader never scans plugins/ (PluginManager.discover_plugins
reads only the configured directory, plugin-repos by default), so what they
found there was a plugin that never runs. _plugin_directory() asks the
manager and answers None without one, which each route already reports as
"not found".

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.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* 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>").

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* 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.

- sports_scroll and sports_game_renderer comments that referred to "this

  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 b11bcfa204 fix(plugins): store and plugin-manager bugs; tidy src/plugin_system (#635)
* fix(store): don't read a ZIP-installed plugin's remote from the LEDMatrix repo

update_plugin looked up remote.origin.url with `git -C <plugin> config
--local` for plugins that are not git checkouts. Under plugin-repos/ git
walks up to the enclosing LEDMatrix repository, so the lookup returned
LEDMatrix's own URL and a plugin missing from the registry was
"reinstalled" from the LEDMatrix repo. Only ask git when the plugin
directory has its own .git, the test _get_local_git_info already uses.

* fix(schema): report each missing required field once, by name

validate_config_against_schema ran its own required-fields loop after
Draft7Validator.iter_errors, which already yields one `required` error
per missing field, so every missing top-level field was listed twice.
The validator's copy also printed the schema's whole `required` list
("Missing required property '['api_key', 'city']'") instead of the field.
Drop the loop and take the field name from the error itself.

* fix(store): stop mangling repository URLs that contain ".git"

install_from_url and fetch_registry_from_url cleaned URLs with
`rstrip('/').replace('.git', '')`, which removes ".git" anywhere:
https://github.com/user/my.github.io became .../myhub.io, so installing
or browsing that repository asked GitHub for one that does not exist.

Add src/plugin_system/repo_urls.py with one anchored normalize_repo_url(),
same_repo() for comparisons, github_owner_repo() and github_api_headers(),
and use them for the five copies of the owner/repo parsing and GitHub
headers in the store and for saved repositories. GitHub URLs are now
recognised by urlparse().hostname everywhere: _get_latest_commit_info
used a substring test, and _install_from_monorepo_api parsed any host.

* fix(store): install a repository whose only branch is not main/master

_install_via_git returned None both when every clone failed and when the
last-resort clone of the repository's default branch succeeded.
_install_plugin_impl papered over it with `and not plugin_path.exists()`;
install_from_url did not, so a repository whose only branch is e.g.
`develop` was cloned, then treated as a failure, then "downloaded" from
main/master archives that do not exist.

After a default-branch clone, return the branch the clone checked out
(read from .git/HEAD), so None means failure and nothing else, and give
both callers the same `branch_used is None` fallback.

* fix(plugins): judge the memory limit on each call's own growth

monitor_call stores `metrics.memory_mb = max(previous, growth)`, and
_check_limits compared that high-water mark with max_memory_mb. It never
decreases, so once one update() grew the process past the limit every
later call raised ResourceLimitExceeded and the circuit breaker kept
reopening. Pass the call's own RSS growth to _check_limits; keep the
high-water mark for reporting and document what it measures.

Remove ResourceMetrics.update_average_execution_time: nothing called it,
and it overwrote the running total with the average.

* fix(plugins): reload_plugin re-reads the manifest from the discovered directory

reload_plugin read `plugins_dir / plugin_id / "manifest.json"`, ignoring
the discovery map and the plugin_dirs rules. For a plugin whose
directory name differs from its manifest id the path did not exist, the
re-read was skipped without a word, and the reload kept the stale
manifest. Resolve the directory with find_plugin_directory, as
load_plugin does.

* fix(plugins): drop the always-null last_display from plugin state info

PluginStateManager reported `last_display` from `_last_display`, which
nothing ever wrote, so it was null for every plugin. Recording it in
PluginExecutor.execute_display would not help: get_state_info's only
reader is the web process, whose PluginManager never calls display().
Remove the field, its dict and get_last_display() (no caller in core,
the web UI or the plugin monorepo).

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* refactor(store): share the rollback and requirements helpers, drop dead code

- install_plugin and _reinstall_with_rollback set aside, discard and
  restore the old copy through _set_aside/_discard_backup/_restore_backup
  instead of two copies of the same blocks.
- The loader and the store run the same pre-pip checks through
  contained_plugin_dir() and requirements_to_install() in plugin_loader.
  They still invoke pip differently (sys.executable -m pip vs. the sudo
  wrapper). `except (BrokenPipeError, OSError)` + `isinstance(e, OSError)`
  becomes `except OSError` checking errno.EPIPE.
- load_module never returns None, so load_plugin's check is gone and the
  docstring says what it raises.
- Remove the always-true JSONSCHEMA_AVAILABLE, the inline re-imports of
  re and permission_utils, the fake status_result object nobody reads,
  hasattr(git_error, 'cmd'), a redundant "merge conflict" test and
  `import traceback` (exc_info=True does it).
- Correct comments: install_from_url names the directory for the
  caller's id when given (not always the manifest id), _get_local_git_info
  saves one git subprocess (not four), _enrich calls two helpers,
  search_plugins documents all its arguments, _find_plugin_path states
  its behaviour instead of a TODO, and history narration is gone.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* refactor(plugins): tidy base_plugin, correct plugin_manager/state comments

- base_plugin: drop the unused `import logging`; get_display_duration
  runs the instance value and the config value through one
  _positive_seconds() helper instead of two copies of the coercion; the
  'static'/'none'/fallback branches of get_vegas_display_mode, which all
  returned FIXED_SEGMENT, are one; fix the mis-indented validate_config
  example; say that get_supported_vegas_modes/get_vegas_segment_width
  are not consulted by core (kept, plugins override them).
- schema_manager: import expand_style_elements normally rather than
  swallowing an ImportError of a core module.
- plugin_manager: the plugins directory is the configured one
  (plugin-repos/ by default), not plugins/; get_config() returns the live
  dict, not a copy, so the interval cache comments say what it saves.
- state_manager: config_version and the file version are not used to
  detect corruption; say what they are.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* refactor(plugins): stop writing data/plugin_operations.json

PluginOperationQueue wrote its finished-operation history to
data/plugin_operations.json after every operation, and read it back only
into its own in-memory list, which only get_operation_history() exposes
-- and nothing calls that. The operation-history endpoint reads
OperationHistory (data/operation_history.json). No code in src/,
web_interface/, scripts/ or test/ reads the file.

Drop the history_file/lazy_load parameters and the load/save code; the
bounded in-memory history stays. web_interface/app.py and the
integration test stop passing the removed arguments. An existing
data/plugin_operations.json is left in place (data/* is gitignored).

ChuckandClaude Opus 5.5 3967a6cffc fix(security): re-harden root sudo helpers; installer fixes; ARCHITECTURE and PERMISSIONS docs (#640)
* docs: add ARCHITECTURE and PERMISSIONS guides

ARCHITECTURE.md maps the processes, the state the display and web
services share through the cache, the display loop, the plugin system,
the web UI and the update path, with links into the code and a
where-to-start table.

PERMISSIONS.md lists who owns what after install, both sudoers files
(and why iptables is not granted), the polkit rule, and which
scripts/fix_perms script to run as which user.

Both are linked from the docs index, along with the MQTT bridge README
and src/common/README.md.

* docs: correct stale setup, service and troubleshooting claims

- README: quick actions run systemctl on ledmatrix.service (run.py), not
  display_controller.py; use_short_date_format has no effect; the
  installer uses system pip with --break-system-packages, not a venv.
- CONFIG_DEBUGGING: LEDMATRIX_DEBUG must be "true"; logs are in journald.
- GETTING_STARTED, WEB_INTERFACE_GUIDE, TROUBLESHOOTING: enabling a
  plugin, plugin settings, brightness and Vegas settings apply without a
  restart; matrix hardware settings still need one.
- TROUBLESHOOTING: install dependencies with sudo so the root service
  sees them; point permission problems at PERMISSIONS.md instead of a
  project-wide chown.
- ADVANCED_FEATURES: real BackgroundDataService stats keys; Vegas hooks
  return VegasDisplayMode and None falls back to capture; cache files
  are 0660; fix_web_permissions.sh runs as the web user and does not
  touch sudoers.
- STARLARK_APPS_GUIDE: only the linux-arm64 pixlet binary is downloaded.
- HOW_TO_RUN_TESTS: test class examples that exist.
- CLAUDE.md: PluginStoreManager, plugin_dirs.py, monorepo installs via
  the Trees API with ZIP fallback, requirements.txt is optional.

* docs: mark deprecated plugin APIs and state manifest fields once

Methods @deprecated("3.7.0") (the set pinned in test_deprecation.py)
were shown as current API in the quick reference, API reference,
advanced guide, development guide and FONT_MANAGER. Each is now marked
deprecated with its replacement. FONT_MANAGER is rewritten around the
current API; the override editor is gone and override methods are
deprecated.

Required manifest fields were stated three different ways. The API
reference now has one section: the 7 schema-required fields, the 4 the
store refuses without, class_name for the loader, and the 8 to set.
The other guides link to it.

  on), a short entry each, and logging advice that matches the code.
- SPORTS_UNIFICATION listed two shared modules and called
  sports_helpers the first; it now lists all six.
- The widgets README lists all 28 registered widgets plus the support
  files, and absorbs the parts that only docs/widget-guide.md had
  (x-options.labels, x-advanced, x-display hidden, plugin-file-manager).
  docs/widget-guide.md is now a pointer to it.

* fix(security): fix_web_permissions.sh re-hardens the root sudo helpers

The script chowns the whole project to the web user. That included
scripts/fix_perms/safe_plugin_rm.sh and safe_pip_install.sh -- the two
helpers /etc/sudoers.d/ledmatrix_web lets the web user run as root -- so
running it turned both into a root shell for whoever can edit them. It
also re-grouped config_secrets.json away from ledmatrix.

After the chown it now does what first_time_install.sh's Steps 11 and
11.1 do: helpers back to root:root 755, and config_secrets.json back to
the web unit's User=:ledmatrix 640. Each step is non-fatal and prints the
manual command if it fails.

Also fixes what the script and its docs claimed: it never configured
sudoers, its closing hint pointed at ./configure_web_sudo.sh (wrong
path), and the README and ADVANCED_FEATURES.md said to run it with sudo,
which it refuses.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(security): validate and harden every sudoers drop-in the scripts write

configure_wifi_permissions.sh copied its rules into
/etc/sudoers.d/ledmatrix_wifi without `visudo -c`. A malformed drop-in
makes sudo refuse every command for every user, which on a headless Pi
leaves no way back in. It now checks first and leaves the installed file
alone when the rules do not parse, as the other two writers do. (It
already used mktemp, so that part of the review did not apply.)

It also grants the two literal commands wifi_manager.py runs for
NetworkManager's shared-mode dnsmasq drop-in -- `cp
/tmp/ledmatrix-nm-dnsmasq.conf .../dnsmasq-shared.d/ledmatrix-captive.conf`
and `rm -f` of that file. The directory's mkdir was granted, the file was
not. Both are pinned in test_sudo_allowlist_covers_calls.py.

configure_web_sudo.sh wrote its rules to /tmp/ledmatrix_web_sudoers_$$,
a predictable name in a world-writable directory; it now uses mktemp with
an EXIT trap, as first_time_install.sh does. It sets mode 440 on the
installed file instead of leaving the temp file's mode, and finds visudo
in /usr/sbin when that is not on the user's PATH, which skipped the
check silently.

* fix(install): escape the project path in the DNS-fix and MQTT unit renderers

install_dns_fix.sh and install_mqtt_bridge.sh substituted
__PROJECT_ROOT_DIR__ with the raw path, while the other three renderers
go through sed_escape_replacement from lib_systemd_render.sh. A checkout
under a path containing `&`, `\` or `|` rendered a corrupted unit from
these two only. Both now source the helper and use it, and a test checks
that every placeholder substitution in scripts/install uses an escaped
value.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(install): stop the installer scripts reporting things that are not true

- first_time_install.sh printed "Password: ledmatrix123" for the setup
  access point. wifi_manager creates it as an open network ("No
  password" on the panel), so it now says so.
- Step 10.1 printed "✓ WiFi management permissions configured" straight
  after its own failure message; install_wifi_monitor.sh printed
  "✓ Package installation completed" after a failed apt install. The
  tick now only follows success.
- Step 7 printed "Web dependencies already installed ... in Step 5" in
  the one branch that runs because Step 5 did not install them, then
  created .web_deps_installed on that basis. It now warns and leaves the
  marker off so the next run retries, as the comment below it intends.
- check_system_compatibility.sh called Debian 12 Bookworm "full
  compatibility confirmed" while first_time_install.sh refuses anything
  but Debian 13. Bookworm, older Debian and non-Debian systems are now
  errors. Its counters used ((X++)), which under `set -e` exits the
  script at the first warning or error (the expression is 0), so the
  check never reached its summary on any system with one.
- configure_web_sudo.sh and configure_wifi_permissions.sh finished by
  testing `sudo -n test -f ...` and `sudo -n nmcli device status`,
  neither of which is granted, so they always reported a failure. They
  now ask `sudo -n -l` about commands the new rules do grant, which
  checks the rule without running anything.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(install): print the completion summary before rebooting

With -y -- and so for every one-shot `curl | bash` install, which always
passes -y -- first_time_install.sh ran `reboot` about 180 lines before
its "Installation Complete / Web UI Access" summary. reboot returns at
once, so the summary printed while the Pi was going down and the SSH
session usually dropped before the web UI address could be read.

The reboot block moves, unchanged, to the very end of the script. The
interactive prompt now also follows the summary. Because the summary now
runs before the -y reboot, its one command that could fail under
`set -Eeuo pipefail` (the SSID lookup, when nmcli reports a connected
device but no active network line) gets `|| true`; a missing SSID was
already handled as "SSID unknown".

one-shot-install.sh prints its "Next steps" after the installer returns,
by which time the reboot is under way, so it now says so, and README's
Quick Install mentions the automatic reboot.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* chore(scripts): correct wrong comments and messages, drop dead code

No behaviour change except the output text noted below.

- 2775 is setgid, not the sticky bit (first_time_install.sh Step 3.1,
  fix_plugin_permissions.sh), and root needs no "PWM hardware access"
  to plugin files.
- The 777 comments in first_time_install.sh Step 3's fallback and
  fix_assets_permissions.sh said root needs it to write. Root ignores
  mode bits; the comments now say what 777 actually opens. The 777
  itself is unchanged.
- apt_remove ends in `|| true`, so Step 12's "Some packages could not be
  removed" branch could never run; it is gone and the helper stays
  non-fatal.
- detect_web_service_user's comment named Step 8 for the web unit
  (install_service.sh installs it in Step 7.5) and now says which
  branch actually runs.
- Step 5 described an "already installed" check that does not exist;
  the ACTUAL_USER comment described the re-exec backwards.
- on_error printed a literal "\n" before "Common fixes:".
- Dead code: one-shot-install.sh's uncalled fix_tmp_permissions,
  LEDMATRIX_ELEVATED=1 (never read) on the sudo re-exec, and
  configure_web_sudo.sh's unused PYTHON_PATH, which also made a missing
  python3 fatal for rules that never mention it.
- start_display.sh / stop_display.sh said "for user: <you>"; the
  service runs as root.

* refactor(fix_perms): fix_cache_permissions.sh uses setup_cache.sh's model

There were two models for /var/cache/ledmatrix. setup_cache.sh (the
installer's Step 2) and install_web_service.sh share it through the
ledmatrix group: root:ledmatrix, 2775, files 660, which is also what
DiskCache relies on to give files the directory's group.
fix_cache_permissions.sh instead made it 777 and re-grouped it to the
invoking user's group, undoing that.

It now runs setup_cache.sh for /var/cache/ledmatrix and keeps its own
handling of ~/.ledmatrix_cache. Dropped: /var/cache/ledmatrix/
placeholder_logos (nothing reads it) and the checks against the
`daemon` user (no service runs as daemon).

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* ci: pin actions/checkout in the Claude workflows, drop template comments

claude.yml and claude-code-review.yml used actions/checkout@v4 while
test.yml and release-version-check.yml pin the v4.2.2 commit SHA; they
now pin the same SHA. The commented-out starter-template settings
(prompt, claude_args, paths, author filter) are removed.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* docs(scripts): index every script and list removal candidates

New scripts/README.md gives one line per top-level script and scripts
directory, marked keep, dev-only or diagnostic, and lists the eight
scripts nothing in the repo refers to as candidates for removal (kept
for now). The install, utils and dev READMEs now list the files they
were missing.

* test: tighten two checks that mutation testing showed were too loose

- The wifi sudoers check matched `visudo -c -f "$TEMP_SUDOERS"` in the
  error report too, so replacing the check with `if false` still passed.
  It now requires the command as the condition.
- The summary test never had the setup access point up, so reinstating
  the bogus "Password: ledmatrix123" line went unnoticed. A case with
  hostapd active now checks the AP is described as open.

ChuckandClaude Opus 5.5 4e61d7248a refactor(web): one error-response path for api_v3 (#624)
* refactor(web): answer unhandled api_v3 errors from one blueprint handler

Fifty-three api_v3 routes ended in a copy of the same catch-all: log the
traceback, return {status, "An error occurred; see logs for details",
details: describe_exception(e)} with a 500. They are replaced by one
errorhandler on the api_v3 blueprint that returns exactly that body.

It lives on the blueprint rather than falling through to app.py's global
handler because the two answers differ: the global one adds
error_code: UNKNOWN_ERROR, and api_client.js sends a body with an
error_code to the error modal and one without to a plain toast. A
blueprint handler also gives tests that mount api_v3 on a bare Flask app
the same answer the real app gives.

Only handlers that were byte-for-byte that shape were removed (matched on
the AST, and each rewritten function re-parsed and compared). Handlers
with their own message, extra keys, operation-history records or cleanup
stay, as does execute_plugin_action's step-1 handler, which sits inside
an `except subprocess.TimeoutExpired` arm that would otherwise turn a
plugin's timeout into a 408.

HTTPExceptions raised inside a route go back as themselves in the global
handler's 4xx shape. Where a removed catch-all used to swallow one (only
delete_plugin_asset's non-silent get_json() is reachable), a malformed
request now gets its 415/400 instead of a 500.

Most of the diff is re-indentation from unwrapping the try blocks;
`git diff -w` shows the real change.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(web): plugin action errors name the real failure, not UnboundLocalError

execute_plugin_action bound a local `logger` in its JSON-parsing arm,
which made `logger` local to the whole function. Every other
`logger.error` in it then raised UnboundLocalError, so a failing OAuth
step-1 script was reported as "UnboundLocalError: cannot access local
variable 'logger'" -- from the step-1 handler, and before the previous
commit from the route's outer catch-all too. Use the module logger.

Found by comparing every api_v3 route's forced-failure response before
and after the catch-all consolidation.

* refactor(web): drop the error category and exception-name code guessing

WebInterfaceError derived an ErrorCategory from every error code and put
it in each structured error body as `error_category`. Nothing reads it:
not the web UI (static/ and templates/), not the tests beyond the ones
pinning the mapping itself, and not any plugin in ledmatrix-plugins. The
enum, the inference table and the JSON key go.

from_exception() could also guess an error code from the exception's
class name ("Config" -> CONFIG_LOAD_FAILED, and so on). Every caller
passes a code, so the guess never ran; error_code is now required.

suggested_fixes stays: the error dialog in static/v3/js/utils/
error_handler.js lists them.

The REST reference loses error_category and says what an unanticipated
exception in an /api/v3 route answers.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* refactor(web): one call for the from_exception error responses

Nine plugin routes built a structured error by hand:

    from src.web_interface.errors import WebInterfaceError
    error = WebInterfaceError.from_exception(e, ErrorCode.X)
    return error_response(error.error_code, error.message,
                          details=error.details, context=error.context,
                          status_code=500)

That is now exception_error_response(e, ErrorCode.X) in api_helpers, so
error_response() is the only structured-error entry point the routes
use. The three operation-history routes never passed the context, and
with_context=False keeps their bodies exactly as they were; a test
compares the helper against the hand-written pair for both forms.

ChuckandClaude Opus 5.5 ece416c4e5 refactor(plugins): one plugin-directory resolver (#623)
* refactor(plugins): one resolver for plugin id -> directory

Five places mapped a plugin id to its directory, each with its own rules
and each re-reading manifests per lookup: PluginManager discovery and
get_plugin_directory, PluginLoader.find_plugin_directory,
PluginStoreManager._find_plugin_path / list_installed_plugins, and
state_reconciliation.disk_plugin_ids. They disagreed on backup dirs,
on whether the manifest id or the directory name is the id, on duplicate
ids and on path safety.

src/plugin_system/plugin_dirs.py now holds the rules once:
PluginDirectoryIndex scans one directory and reads each manifest once;
resolve_plugin_dir() searches directories in order. What legitimately
differs per caller is an explicit argument: search dirs (discovery and
the loader: configured dir only; the store: configured then sibling
plugins/), ledmatrix- prefix (not for the store), case folding (loader
only), manifest pass (not for get_plugin_directory, whose discovery map
already holds it).

Behaviour changes, all for layouts installs do not produce:
- a directory whose manifest declares the id beats one merely named for
  it (discovery already worked this way; the loader and store now agree)
- the store searches the configured dir completely before plugins/
- backup and hidden dirs are skipped everywhere (the loader's case and
  manifest scans and list_installed_plugins used to return them)
- duplicate ids resolve deterministically (exact name, then
  ledmatrix-<id>, then by name) with a one-time warning; discovery no
  longer lists the id twice
- disk_plugin_ids / list_installed_plugins report manifest ids, falling
  back to the directory name; auto-update looks the directory up
- ids that are not one plain path segment resolve to nothing in every
  caller (the loader used to truncate them, the store to join them)

The .standalone-backup- marker is one constant, BACKUP_MARKER, used by
store_manager's rename-aside names and every lookup.

ChuckandClaude Opus 5.5 13bbb537f3 refactor(web): one logging setup and one TTL cache for the web process (#621)
* refactor(web): use src.logging_config in the web process; routine requests to DEBUG

The web interface had its own logging setup (web_interface/logging_config.py)
that replaced the root handlers with a plain stdout formatter. The web
service's journal lines therefore never carried a syslog priority, so
`journalctl -p err -u ledmatrix-web` returned nothing while errors were
logged, and the line shape differed from the display's (the log viewer's
prefix stripping only matched the display format). It also ran after the
module-level managers were built, so their INFO lines at import (including
"Re-removed N uninstalled plugin(s)") were dropped.

app.py now calls src.logging_config.setup_logging() first thing, the same as
run.py: journald priorities under systemd, LEDMATRIX_DEBUG honoured,
LEDMATRIX_JSON_LOGGING still selects JSON.

Per-request logging moves to web_interface/request_logging.py. Every request
used to be logged at INFO, so the UI's polling filled the journal
("GET /api/v3/errors/summary - 200" every minute per tab). Now a successful
GET/HEAD/OPTIONS is DEBUG, a successful write is INFO, 4xx WARNING, 5xx
ERROR. Durations use perf_counter and print to 0.1ms.

The duplicate module is deleted; nothing else imported it.

* refactor(web): one thread-safe TTL cache for the web process

web_interface/cache.py becomes a small TTLCache class (lock-guarded,
monotonic clock) with the existing get_cached/set_cached/delete_cached/
invalidate_cache helpers kept on top of a shared instance, so the api_v3
callers are unchanged.

Bugs fixed:
- set_cached(ttl_seconds=...) ignored its TTL; only the reader's value
  counted and get_cached defaulted to 60s. An entry now expires after the TTL
  it was stored with; a reader's ttl_seconds can only shorten that. Both
  current callers pass the same value on both sides (fonts_catalog 300s,
  system_status 10s), so their observable TTLs are unchanged.
- get_cached deleted expired keys without a lock; two threads reading the
  same expired key could raise KeyError (reproduced), which the endpoints
  turned into a 500.

app.py's two hand-rolled systemctl caches (_ap_mode_cache, 30s, and
_ledmatrix_service_cache, 15s) now share one helper over a private
TTLCache, with the same TTLs. The AP-mode check used to retry on every
request after a failure (and log an ERROR each time); a failure now keeps the
last known answer for the TTL, as the display-service check already did. With
no systemctl at all (a dev machine) it answers False without forking.

Left alone as not TTL memoisation: the gzip cache (size-bounded, keyed by URL
and version), the settings search index (keyed by installed-plugin set), the
widget bundle (keyed by file fingerprint) and CacheManager (cross-process).

ChuckandClaude Opus 5.5 afe9001aed refactor(fonts): one BDF loader and one BDF rasterizer (#627)
* refactor(fonts): one BDF loader and one BDF rasterizer

BDF faces were loaded three ways (FontManager._load_bdf_font,
element_style._load_bdf, DisplayManager._load_fonts) and drawn by two
copies of the same per-pixel loop (DisplayManager._draw_bdf_text and the
plugin test harness's "replicated" copy), which golden images and
check_plugin/dev_server previews rely on matching the panel.

src/common/bdf_font.py now owns both:
- load_bdf_face(path, size) -> (face, realised_px): native-strike fallback
  for sizes the file lacks, one bounded LRU cache keyed on path, size and
  mtime. FontManager, element_style and DisplayManager delegate to it;
  read_bdf_native_size moves here (the old names delegate).
- draw_bdf_text(draw, text, x, y, face, color, clip): builds each glyph as
  a 1-bit mask and fills it with ImageDraw.bitmap instead of a draw.point
  per pixel. A blending Draw (RGB image, "RGBA" mode) keeps the point path
  so translucent colours still blend.

Pixel-identical: 220,032 renders (every bundled BDF at native and
off-strike sizes, 14 strings, 4 colours, clipped on every edge, through
each old loader x rasterizer) match origin/main byte for byte.
test/test_bdf_font.py keeps a lightweight version against a frozen copy of
the old loop. DisplayManager._draw_bdf_text goes from 1.4-23 ms to about
0.1 ms per string (the old loop re-read FreeType's buffer as a Python list
for every pixel).

* fix(testing): harness calendar_font is sized like the panel's

VisualTestDisplayManager built its 5x7 calendar_font / bdf_5x7_font as a
bare freetype.Face. With no size set its ascender reads 0, so BDF text
drawn with it landed 6px above where DisplayManager draws it -- entirely
off the canvas at y=0 -- and get_font_height() returned 0. Golden images
and check_plugin / dev_server previews showed text the panel does not.

Load it through load_bdf_face at the panel's 7px, so it is the very face
DisplayManager uses. Across the differential run this changes only the
cases drawn with the harness's own calendar_font (968 of 220,032), which
now match the panel's output.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(fonts): one BDF face per thread

The shared face cache now hands every loader (FontManager, element_style,
DisplayManager, the harness) the same freetype.Face. FreeType does not allow
two threads to use one face at once, since load_char rewrites its glyph
slot, so key the cache by thread as well.

ChuckandClaude Opus 5.5 abedc46104 refactor(sports): merge the sports_shared/sports_card twins that behave identically (#626)
* refactor(sports): wrap the sports_card twins that behave identically

SportsCoreSharedMixin (switch mode, via each scoreboard's sports.py) and
sports_card (scroll/Vegas mode, via game_renderer.py) carried the same
helpers twice. test/test_sports_twins.py now calls every pair with the
same inputs -- the eight scoreboards' harness fixture games in flat,
flat+nested and nested-only shapes, plus edge cases (favourites by id and
abbreviation, NRL's colliding abbreviations, missing and non-numeric
scores, bad zones, out-of-range dates, shared font faces).

Identical pairs become thin wrappers over the sports_card function:
_card_option, _vs_text, _format_game_time, _coerce_rgb, _crisp_size (with
the class's own tables), _unshare_element_fonts (with the class's own
element map, via a new optional argument), and the colour/month/weekday/
font-grid tables (dicts copied, not aliased). _format_game_date shares the
card's formatting body but keeps its own setting, weekday zone and month
table; _schema_font_size shares the parser but keeps its per-class cache,
because a reloaded plugin gets new classes and a shared path cache would
stop it seeing an edited schema. _resolve_font_size agrees but keeps its
body so it still dispatches through the overridable hooks.

No behaviour change: old and new mixin/card agree on all 22,994
comparisons over the test corpus, and the pairs that do differ
(favourite-result colours on nested payloads and by favourites source,
the weekday's timezone, the element-name map, per-mode colours) are left
alone and pinned in TestPinnedDivergence for an owner decision.

* test(sports): pin that an ambiguous NRL abbreviation tints in both modes

NRL's resolver passes a shared abbreviation ("NEW") through with an error
and its _is_favorite_game matches ids only, but both favourite-colour
helpers match on abbreviation as well, so both display modes tint a
Knights or Warriors result for a user who typed "NEW". The twins agree;
neither consults the _favorite_key seam. Pinned so a fix is deliberate.

ChuckandClaude Opus 5.5 82f3a3a3e4 fix(redaction): make credential redaction linear, not quadratic (#631)
* fix(redaction): make URL-userinfo redaction linear, not quadratic

_REDACT_URL_USERINFO could start a match at every letter of a run of
scheme characters, and each attempt read to the end of the run looking
for `://`. On a long unbroken run of letters or digits (a hex digest, an
ID, part of a response body) that is quadratic: 1.6s for 20k characters.

The display service redacts every message, stack trace and context value
it publishes in the error snapshot, holding the aggregator lock, and
re.sub holds the GIL for the whole call, so one such exception stalled
every thread, render loop included (~0.5s measured for 20k chars of hex).
It also made test_snapshot_stays_small the slowest test in the suite by
far: 142s of a 383s run, 139s of it in this one regex.

A match may now only start where a run of scheme characters starts
(negative lookbehind). Leading digits and `+.-` are captured in group 1
so the substitution restores them, and the scheme still has to start
with a letter, so what gets redacted is unchanged: old and new output
were identical on 300k fuzzed inputs. 20k chars now take ~0.5ms, 200k
~6ms, and test_snapshot_stays_small takes 0.8s.

test/test_redaction.py pins the exact output for schemes that begin after
digits or `+.-`, and bounds 50k-character runs at 1s; against the old
pattern those timing tests fail at 3-11s each.

Claude-Session: https://claude.ai/code/session_01KMXdS2S4NXTJ8ET96GymhK

* fix(redaction): make Authorization-header redaction linear too

_REDACT_AUTH_HEADER matched the value's opening as `\s*["\']?\s*`: two
`\s*` separated only by an optional quote. With no quote, a whitespace
run could be split between them in every possible way, and when no
credential followed (end of text, or `,` `"` `<` ...) the engine tried
them all before giving up: quadratic, 8s for `authorization:` and 20k
spaces, 17s with `Proxy-Authorization:` (tried again at the inner
`authorization`). Same stall as the URL pattern: re.sub holds the GIL,
and the display service redacts everything it publishes.

The quote and the whitespace after it are now one optional unit,
`\s*(?:["\']\s*)?`, which matches the same strings with only one way to
split them. Output is identical to the old pattern on 300k fuzzed
inputs; 20k spaces now take ~1.6ms. A scan of all three redaction
patterns over prefix/run/suffix shapes finds none left that scales
superlinearly.

test/test_redaction.py pins exact output for quoted, tabbed, multi-line
and credential-less headers, and bounds header + 20k whitespace at 1s;
against the previous pattern those fail at 8-17s each.

ChuckandClaude Opus 5.5 f3894916a9 feat(web): show which plugins use each font; warn before deleting one (#619)
* feat(web): show which plugins use each font, warn before deleting one

The Fonts tab lists font files from the web process's own scan, and the
plugins that register fonts run in the display process, so the tab had no
way to say whether a font was in use before deleting it.

The display service now publishes {catalog key: [plugin ids]} to the
shared cache (font_usage_snapshot, src/font_usage.py), built from the
loaded plugins' FontManager.register_manager_font() registrations. A
daemon thread checks every 10 s and writes only when the usage changed
(plus a daily refresh so cache cleanup cannot expire it); it never raises.
Families, aliases (press_start, four_by_six, ...) and paths are resolved
through FontManager's catalog to the file stem the Fonts tab keys rows by;
fonts outside assets/fonts are left out. Unloading a plugin drops its
registrations (new FontManager.forget_manager_fonts).

GET /api/v3/fonts/catalog merges used_by into each row per request (the
5-minute scan cache is copied, never edited): a list of plugin ids, or
null when the display service has not reported. The tab shows a Used by
column ("unknown" / "-" / ids, rendered as text) and deleting an in-use
font names the plugins in the confirmation, from a fresh read. The server
still refuses only system fonts. Catalog fetches bypass the browser's
5-second API cache, which otherwise served the pre-delete list.

ChuckandClaude Opus 5.5 9a1f94f793 fix(starlark): blank app locations use the device location, not San Francisco (#617)
* fix(starlark): blank app locations use the device location, not San Francisco

A Starlark (Tidbyt) app whose Location field is blank rendered at its
author's hard-coded DEFAULT_LOCATION -- usually San Francisco -- even with
the device city set under General settings. A user in Charlotte, NC got San
Francisco weather and radar with nothing in config.json to explain it.

src/device_location.py fills unset location fields at render time (display
plugin and the web standalone render): the device city is geocoded once via
Open-Meteo, preferring a match in the configured state/country, and cached
permanently. A saved location always wins; if the lookup fails the field is
dropped so the app uses its own default, and the failure is not retried for
30 minutes.

Also fixes the config form: clearing a location omitted the key, and the
save merges, so the old value could never be removed.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* docs(starlark): say what happens when the device location can't be used

A blank app Location only renders at the device's city when one is set and
the Open-Meteo lookup finds it. With no city, no match, or the geocoder
unreachable (retried after 30 minutes), the app gets no location and keeps
its author's default. The guide, the config page hint, CONFIG_REFERENCE and
the CHANGELOG entry now say so.

ChuckandClaude Opus 5.5 61e462c635 refactor: remove the skin system and the unused src/base_classes package (#615)
* refactor: remove the skin system

Skins never rendered with the current scoreboard plugins: the only hook was
SportsCore._render_game in src/base_classes, which no plugin builds on, so
the UI and store already treated them as unsupported. The owner decided on
2026-09-23 to remove them outright.

Removed src/skin_system/ (runtime, base class, fixtures), skins/,
scripts/validate_skin.py and their tests; the store's "type": "skin"
installer, uninstaller and hide/refuse filters (the official registry lists
no skins); SchemaManager.inject_skin_selector; and GET /api/v3/skins.

Stored skin/skin_options config values are handled in the next commit.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* fix(config): drop retired skin/skin_options keys instead of validating them

A config.json written while the skin system existed can carry skin and
skin_options in any plugin section, and most plugin schemas set
additionalProperties: false. They are no longer core plugin properties;
RETIRED_PLUGIN_KEYS in schema_manager lists them and
drop_retired_plugin_keys removes them (unless the plugin's own schema
declares the name) in prepare_plugin_config, which loading, hot reload,
GET /plugins/config and both web saves already share, and in
validate_config_against_schema for callers that validate a raw section.
POST /plugins/config and /config/main also drop them from the stored
section they merge into, so they leave config.json on the next save.

Tests cover the load path (real PluginManager.load_plugin: no schema
warning, not degraded), raw and prepared validation,
validate_all_plugin_configs, and the JSON, form and /config/main saves.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* refactor: remove the unused src/base_classes package

No scoreboard plugin builds on src.base_classes: the nine monorepo
scoreboards ship their own sports.py and share code through src/common
(docs/SPORTS_UNIFICATION.md), and none of the third-party registry plugins
imports it. The one import anywhere, baseball-scoreboard's
rankings_manager.py, is a lazy import of ESPNDataSource in a class nothing
instantiates.

Removed the package and the eight test files that only tested it
(test_api_extractors, test_data_sources, test_sports_base_characterization,
test_sports_capabilities, test_sports_core_promotions,
test_sports_logo_cache_bounded, test_sports_modes_promotions,
test_sports_odds_fanout). test_common_is_hardware_free no longer lists
src.base_classes as a forbidden import, and comments in sports_helpers.py
and base_odds_manager.py stop pointing at it.

section of REST_API_REFERENCE.md), the skin section of CLAUDE.md and the
term in PRODUCT.md. SPORTS_UNIFICATION.md now says src/base_classes was

* fix(store): hide and refuse registry entries that aren't plugins

The skin filters went with the skin system, but a custom registry can still
list "type": "skin" entries, and installing one as a plugin would unpack it
into the plugins directory. PluginStoreManager.is_plugin_entry() (a missing
type means plugin) now hides non-plugin entries from the store and
custom-registry listings, and install refuses them, in the route with a
clear 400 and in _install_plugin_impl for any other caller.

ChuckandClaude Opus 5.5 4a1fd7464a fix(errors): serve /api/v3/errors/* from the display service; add a Plugin errors panel (#614)
* fix(errors): serve /api/v3/errors/* from the display service's aggregator

The error aggregator is a per-process singleton and only the display
service runs plugins, so only its aggregator records anything. The routes
read the web process's own, empty one and always reported no errors.

The display service now publishes a bounded snapshot of its aggregator to
the shared cache (plugin_error_snapshot) from a daemon thread: at most once
every 10 s and only when something changed, never raising into the caller.
The routes read it and keep their response shapes, adding
snapshot_available, generated_at and clear_pending; exception text has
credentials redacted.

POST /errors/clear writes a clear request (plugin_error_clear_request) that
the display applies on its next 5 s tick via the new clear_before(), which
keeps errors recorded after the cutoff and rebuilds the counts. Until the
snapshot acknowledges the request, reads hide everything before the cutoff,
so a snapshot written just before the click cannot bring errors back. Adds
"all": true; cleared_count is null when only the display can know it.

Keeping only a traceback's tail (or clipping a message) could cut an

free-text field of the snapshot first. The patterns move to a Flask-free
src/redaction.py so the display service can use them; redact_text in the web
error handler uses the same function, unchanged in behaviour.

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).

ChuckandClaude Opus 5.5 269385c97c fix(config): write config.json through one durable atomic writer (#611)
save_config() opened config.json with 'w' and streamed json.dump into it,
so a power cut or an unencodable value left the file truncated.
save_config_atomic() renamed a temp file into place but never fsynced it,
rewrote the unchanged secrets file on every save, and re-parsed every
backup to rotate them. save_raw_file_content() had its own third copy.

All of them, plus rollback and config creation from the template, now go
through atomic_write_text(): temp file in the same directory, fsync,
final mode set before the rename, rename (retried on Windows while a
reader holds the file), directory fsync. A root save copies the previous
owner onto the new file so a rename by the display service no longer
hands config.json to root; the shared-group fix-up is unchanged. The
mode is chosen from the file name, so a "secrets" directory in the
install path no longer makes config.json 0640.

The secrets file is rewritten only when its content changes, and backup
rotation works from filenames alone. Backups keep their names
(config/backups/config.json.backup.<version>, paired secrets backup) and
the five newest are kept, as before.

ChuckandClaude Opus 5.5 604f58ff07 feat: deprecate unused plugin-facing methods for removal in 3.7.0 (#610)
35 methods on CacheManager, DisplayManager, FontManager and PluginManager
have no caller in core, the ledmatrix-plugins monorepo or the registry's
third-party plugins, but plugins live elsewhere, so they stay for one
release. src.deprecation.deprecated logs a warning (and emits a
DeprecationWarning) the first time each is called in a process, naming the
release that removes it. The list and replacements are in CHANGELOG and
PLUGIN_API_REFERENCE's new Deprecated APIs section; a test pins the set.

ChuckandClaude Opus 5.5 342e9164b8 fix: settings the display ignored, a memory leak, and the plugin card handler (#605)
* fix(errors): stop affected_plugins growing without bound

Each repeat of an error pattern appended every plugin in the time window to
the pattern's list again, so a plugin failing in a loop grew the display
process's memory without limit: 3,000 errors from three plugins reached 2.5
million entries. Keep the list unique.

* fix(fonts): load a BDF font at its native size instead of PIL's default

FreeType rejects any size but a BDF strike's own, and FontManager answered
that with ImageFont.load_default() -- a different typeface -- so 5x7.bdf
requested at 8 or 10px rendered as PIL's default font. Retry at the native
strike, as element_style already does.

* fix(web): plugin toggle failures no longer claim "operation in progress"

Every exception in POST /plugins/toggle was mapped to
PLUGIN_OPERATION_CONFLICT, so any failure told the user "A plugin operation
is already in progress". Report the failure as what it is, and record the
plugin id in the operation history for form posts too (it read a `data`
variable that only the JSON path set).

* fix(web): route plugin card clicks through handlePluginAction

The document-level delegation checked `typeof handlePluginAction`, which is
scoped inside the plugin-manager IIFE and so never visible to it. Every card
click took a copied fallback that stopped propagation (the grid's own
listener never ran), confirmed an uninstall twice, and sent Starlark app
uninstalls to POST /plugins/uninstall instead of DELETE /starlark/apps/<id>.
Expose the handler on window and delegate to it.

Also run every test/js/unit suite under pytest: they need only node, but CI
ran one of the eight.

* fix(display): apply Rotation durations, WiFi messages and Vegas settings

Three settings the web UI saves never reached the display:

- Rotation & Durations: display.display_durations was never read. Every
  plugin inherits get_display_duration() and the plugin was asked first. A
  saved value now wins. The page shows unsaved screens blank with the
  plugin's own duration as a placeholder, and saving a blank removes the
  override, so one save no longer pins every screen.
- WiFi status overlay: the controller looked for wifi_status.json one
  directory above the repo. Both sides now use
  wifi_manager.get_wifi_status_path(). The message is written by rename so
  the display never reads it half-written, and the resumed plugin redraws the
  whole panel afterwards.
- Vegas: nothing called coordinator.update_config(), so saved Vegas settings
  never reached a running scroll. They are now queued when
  display.vegas_scroll changes, and applied while Vegas is stopped too, so a
  disable then re-enable works. The follower's scroll-speed default (75) now
  matches VegasModeConfig's (50).

Also throttles Vegas's per-frame live-priority scan to 4Hz. It cost 139us
per frame on a Pi 4 with two scoreboards (1.7% of a 125fps frame) and grows
with each plugin.

* fix: keep affected_plugins order when serialized; guard non-Element targets

ErrorPattern.to_dict() ran the now-ordered list through set(), so
get_error_summary() listed plugins in an unstable order. The document-level
card-action listener called event.target.closest() without checking the
target is an Element.

claude[bot]andClaude Opus 5 0903f9055f docs(changelog): record #600 and #602 in the 3.5.0 section (#603)
* docs(changelog): record #600 in the 3.5.0 section

#600 merged into main while the release PR was open, so the 3.5.0 section
went in without it. Nothing in that PR touched the CHANGELOG, and no check
covers "everything merged since the last tag is written down", so tagging
v3.5.0 as main stands would ship the standings-endpoint fix undocumented.

The entry goes under Sports data, next to the other ESPN fetch changes, and
is written from the commit: what the old order did, why a college league's
200 defeated the 404 fallback, and what is now treated as routine.

No version change: 3.5.0 is not tagged yet, so this belongs in that section
rather than a new one. `scripts/check_release_version.py v3.5.0` still passes.

* docs(changelog): record #602 in the 3.5.0 section

#602 merged into main after #601, the same way #600 merged during it, and
also touched no CHANGELOG. So the section was still a commit short of what
v3.5.0 will actually ship.

It gets its own "Installers" subsection rather than a line under "Small
fixes": a malformed drop-in in /etc/sudoers.d makes sudo refuse every command
for every user, which on a headless Pi is unrecoverable over SSH. That is not
a small fix, and someone reading the release notes to decide whether to update
should see it.

Written from the commit: what both installers did, what `visudo -c` now gates,
and the fixed /tmp path that mktemp replaced.

`scripts/check_release_version.py v3.5.0` still passes, and this branch is
rebased onto 967f3a05 so the section now covers every commit since v3.4.0.

claude[bot]andClaude Opus 5 21c8a54f68 chore: prepare the 3.5.0 release (#601)
* chore: prepare the 3.5.0 release

Turns the CHANGELOG's Unreleased section into `## 3.5.0` and bumps
`src.__version__`, the value plugin `ledmatrix_min_version` floors compare
against. No behaviour change; nothing outside the CHANGELOG, `src/__init__.py`
and one docs line is touched.

The staged entries are reshaped into the `### ` subsections every released
section already uses, and the "new modules a plugin may import via `src.*`"
block moves to the top as the plugin-facing summary, the same shape as 3.4.0.
Its floor, written as "the release that ships this" while it was staged, is now
3.5.0, and `docs/SPORTS_UNIFICATION.md` says 3.5.0 for `sports_helpers.py`
instead of "(unreleased)".

Four merged changes had never been written down. They are added under the
subsection each belongs to, from the commits and their measurements:

- the idle back-off clamped to the next kickoff (#599)
- concurrent ESPN date chunks (#596)
- the three web routes that consulted plugin manifests before anything had
  discovered plugins, one of which wrote a plugin API key to config.json in
  plain text (#594)
- the cache permission fix and its systemd unit changes (#593), which get
  their own subsection

No tag and no release: `scripts/check_release_version.py v3.5.0` passes, so
tagging is a separate, deliberate step.

* ci: let Claude Code Review run on PRs the Claude app opens

The review action refuses a workflow whose actor is a GitHub App unless the
app is named in `allowed_bots`, which this workflow never set:

  Actor is a GitHub App: claude[bot]
  Actor type: Bot
  Action failed with error: Workflow initiated by non-human actor: claude
  (type: Bot). Add bot to allowed_bots list or use '*' to allow all bots.

It aborts about two seconds in, before the diff is read, so the check is red
on every such PR and re-running cannot help: the actor does not change. Until
now no PR here had a bot author, so nothing tripped it.

`'claude'` rather than `'*'`: the action lowercases each entry and strips a
trailing `[bot]` before comparing it to the actor
(`isAllowedBot` in `src/github/validation/actor.ts`), so this admits
`claude[bot]` and no other app. `'*'` would admit any app that can trigger a
workflow here, with a prompt it controls — the action's own docs warn about
that on public repositories, and this one is public.

The write-permission check already allowed the app; `checkHumanActor` was the
only gate.

ChuckandClaude Opus 5 19686ab761 fix(web): plugin settings form shows schema defaults for unsaved keys (#597)
The server-rendered plugin settings partial rendered straight from the
saved config, so an option added in a plugin update (geochron 1.2.0's
show_date / show_date_line, default true) drew as an unchecked box, and
the save route's missing-checkbox handling then stored it as false.
Enum dropdowns likewise showed their first option instead of the default.

- _load_plugin_config_partial runs the stored section through
  prepare_plugin_config (as GET /plugins/config does) before masking
  secrets, so a secret's schema default is masked too.
- render_field falls back to the field's own default, covering children
  of objects that declare a default of their own (where the defaults
  extraction stops).
- The legacy-boolean parity test now compares against the config the
  plugin actually runs with (defaults included).

ChuckandClaude Opus 5 116abb0daa fix: September 16 core audit — partial saves, asset path safety, auto-update, display settings the library refuses, scroll speed (#595)
* fix(sports): share the ESPN rejected-range memo with the background service

BackgroundDataService always sent a season range first and, on a 400,
fell back to chunks without recording the rejection, so every background
season fetch spent a doomed request and live scoreboards learned nothing
from it (or it from them). The worker now consults and sets the same
6-hour memo fetch_espn_scoreboard() uses: a known rejection goes straight
to month/day chunks, and if every chunk fails the range is asked once for
a real error without re-spending the chunks.

* fix(web): keep plugin asset and action routes inside their directories

POST /plugins/assets/upload, GET /plugins/assets/list and POST
/plugins/assets/delete joined the request's plugin_id onto assets/plugins
unchecked, so '../../config' created, wrote, listed and deleted outside
it. #561 guarded only the route that serves the files. All three now go
through path_safety.resolve_under and answer 400 for anything but a
plain name, and delete only unlinks a metadata path that resolves into
that plugin's uploads directory.

PluginManager.get_plugin_directory refuses ids that are not one plain
path segment, so /plugins/action (which runs a manifest script from the
returned directory) and every other caller get the guard; the action
route also rejects such ids up front, covering its no-manager fallback.

* fix(web): report a no-op plugin update as already up to date

update_plugin() returns True both for a real update and for "nothing to
do" (a ZIP-installed monorepo plugin already at the registry version, a
bundled plugin). With no git commit to compare, POST /plugins/update
called every such success "updated successfully", so Check & Update All
counted most official plugins as updated on every run.

The route now reads what changed off the plugin itself (commit, else
manifest version, else last_updated) and returns data.update_status
(updated / up_to_date / local_only). The update-all toast is summarised
by PluginInstallManager.summarizeUpdateResults from that status, falling
back to the message for older servers.

* fix(sports): scoreboard scroll speed no longer follows target_fps

sports_scroll computed the crisp speed ladder against the global
target_fps whenever limit_refresh_rate_hz was the 100 Hz default. Since
frame-locked presentation (#545) the helper steps a fixed number of whole
pixels per presented frame and the panel presents at its real refresh, so
the General tab's "Scroll Frame Rate" became a speed multiplier: 60 ran a
50 px/s scoreboard at 100 px/s, 200 ran it at 25 px/s.

The ladder now uses the display manager's refresh_hz, then
display.hardware.limit_refresh_rate_hz, then the default. target_fps is
not consulted. Docstrings now say scroll_delay is ignored for pacing (no
behaviour change there) and describe the fixed-step model.

Tests: replace the tests that pinned target_fps as the ladder refresh and
described time-based stepping; assert speed independence from target_fps
(unit and end-to-end presented px/s against the real helper), that the
fixed per-frame step is applied, and that scroll_delay does not change
speed.

* fix(web): escape registry and upload values in plugin manager inline handlers

The store, saved-repository and custom-registry buttons built
onclick='...(${JSON.stringify(id)})...'. JSON.stringify leaves ' alone,
so a custom registry entry whose id contained ' closed the attribute and
added its own handler. One helper, jsStringAttr(), now HTML-escapes the
JSON literal for every one of those handlers, and the store View button
opens only http(s) repo links.

The live window.updateImageList (plugins_manager.js loads last, so its
copy wins over the file-upload widget's) wrote the uploaded file's
original name, path and ids into markup raw; they are escaped now.

* fix(update): let the root pip wrapper install web_interface/requirements.txt

Update Code, the automatic update's health check and Install Base
Requirements install web_interface/requirements.txt through
safe_pip_install.sh, which only allowed the root requirements.txt. The
first commit changing that file would fail its dependency install, and
the automatic updater rolls back any update whose dependencies did not
install -- on every device, for every newer commit.

The wrapper now lists both core requirement files. Only their folders
are resolved, so a requirements.txt symlinked out of the project is
compared by its target and refused (previously the root file's own
symlink target was what got allowed). The updater's file list is a
named constant, and a test runs the real wrapper (pip stubbed) on
every file Update Code and the rollback install.

* fix(web): do not retry plugin requests that got an HTTP answer

PluginAPI.request wrapped everything that was not a structured error as
NETWORK_ERROR: a proxy's 502 HTML page (response.json() throws) and a
JSON error without error_code included. Check & Update All retries
NETWORK_ERROR, so those updates were re-sent five more times with
backoff, contrary to the #587 contract that an HTTP error response is
the server's answer.

NETWORK_ERROR now means only that fetch() rejected. Any HTTP response
without an error_code, or with a body that is not JSON, is API_ERROR
with the HTTP status attached. Tested against the shipped api_client.js.

* fix(scroll): restart the stats window when an idle gap is dropped by size

#582 dropped an idle gap from the frame stats two ways: the reset_scroll()
sentinel, which also restarts the 5s window timer, and a size guard for
scrollers that never call reset_scroll(), which did not. On that path the
first real frame after the gap found the boundary overdue and logged a
stats line for a one-frame window. Both paths now share one seeding helper.

* fix(update): leave plugins alone when update_core's own rollback fails

update_core returns rollback_failed directly when a partial pull or an
update whose health check never started cannot be rolled back. run()
only held plugins back for 'verifying', so those devices still got new
plugin versions and a display restart on top of a core in an unknown
state -- the opposite of what the health-check path does, and of the
3.4.0 changelog (plugins are left alone if the rollback fails).

* docs(api): make the REST reference match the api_v3 package

Every documented request body, query parameter and response shape was
re-checked against the handlers in web_interface/blueprints/api_v3/.
Fixes calls that failed as documented (repo_url, action_id/params,
files/image_id, font_file+font_family, ?font=, cache key,
auto_enable_ap_mode, plugin limit keys), removes the font-override
endpoints dropped in #566, corrects response shapes (plugins/config,
plugins/schema, health, metrics, operation history, github-status,
fonts/catalog, cache/list, logs, wifi, on-demand, SSE streams), and adds
the 26 routes it omitted (backup, system auto-update/git, wifi radio,
starlark editor, MQTT bridge, status endpoints, skins).

Documents the merge semantics of partial JSON saves to /config/main and
/plugins/config and the dim-schedule POST accepting GET's days shape,
which land in the same change set. Replaces app.py line numbers and the
removed api_v3.py path with file and function names.

* fix(web): remove the General-tab plugin system toggles that did nothing

plugin_system.auto_discover, auto_load_enabled and development_mode had
General-tab toggles whose help tips promised dormant plugins and verbose
logging, but nothing reads them: every enabled plugin is discovered and
loaded regardless. Remove the three toggles.

The keys stay tolerated in stored configs. The save handler now stores
a flag only when a client sends it; treating a missing key as an
unchecked box would otherwise rewrite all three to false on every
General-tab save, which still posts plugins_directory.

* refactor(scroll): remove dead code left by #523/#570

- Drop the optional scipy.ndimage import and HAS_SCIPY; nothing read
  them since the numpy blend replaced the scipy path.
- Drop ScrollHelper._last_integer_position and frame_time_target, which
  were written but never read.
- Keep target_fps and set_target_fps() but document them as
  informational: nothing paces off them, yet ledmatrix-elections'
  test_scroll_pacing.py reads helper.target_fps back and third-party
  plugins may call the setter.
- Fix stale comments: fixed_pixels_per_frame's "use scroll_delay to
  throttle", set_sub_pixel_scrolling's "default: True", and
  set_frame_based_scrolling's claim that it steps.

The plugins monorepo was grepped for every removed name; none is used.

* docs(fonts): point plugins at plugin_manager.font_manager; drop removed overrides UI

FONT_MANAGER.md told plugins to read display_manager.font_manager, which
does not exist, so a plugin following it failed to load with
AttributeError. The shared FontManager lives on the PluginManager and
BasePlugin._get_font_manager() returns it (with a fallback for harnesses).

Also removes the Fonts-tab override workflow and element-override panels
that #566 deleted, from FONT_MANAGER.md and WEB_INTERFACE_GUIDE.md.

* docs(store): search via /plugins/store/list?query=; send Content-Type on registry curls

/plugins/store/search does not exist (404) and the list endpoint reads
query, not q. The registry guide's curl examples omitted the JSON
Content-Type, so the handlers saw an empty body and answered 400.

* fix(config): use the shared core-key list in the last three private copies

StartupValidator warned "Plugin 'auto_update' is enabled but not found" on
every display start with auto-update or a dim schedule on; the reserved
plugin-id check missed auto_update, sync, location and the rest; and
ConfigManager's (uncalled) orphan cleanup would have deleted display,
schedule and auto_update. All three now read src/core_config_keys.py, which
also gains CORE_SECRETS_KEYS for the github/youtube secrets sections.

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

* fix(web): partial JSON saves to /config/main change only what they send

A JSON body with one field reset every checkbox in the sections it touched:
the MQTT bridge's brightness slider turned off disable_hardware_pulsing,
inverse_colors, show_refresh_rate and use_short_date_format, and a
timezone-only save turned off web-UI autostart and weekly auto-updates.
Missing-means-unchecked now applies only to form posts: form-encoded bodies
and the v3 forms, which mark themselves with a hidden __form_section input.

Also on the config routes:
- vegas_min/max_cycle_duration no longer match the generic *_duration rule,
  so they stop landing in display_durations and a blank one no longer
  rejects the whole Display save;
- saving from the Raw JSON editor calls start_setup_if_needed like the
  General form, so enabling auto-update there finishes its setup;
- the schedule and dim-schedule POSTs accept the per-day days.<day> shape
  their GETs return, as well as the flat form keys.

* fix(scripts): install plugin dependencies from the configured plugins directory

install_plugin_dependencies.sh scanned only plugins/, but the Plugin
Store installs into plugin_system.plugins_directory (default
plugin-repos), so the documented "Recommended" fix found 0 plugins on
every store install. It now reads plugins_directory from
config/config.json (relative to the project root or absolute, default
plugin-repos) and also scans plugins/ for dev symlinks, installing a
plugin reached through both only once.

With set -e alone, `pip ... | tee` took tee's exit status, so a failed
pip install was reported as success; set -o pipefail.

* docs: replace stale API names, line numbers and the api_v3.py path

- ADVANCED_FEATURES: StreamManager methods that exist
  (get_next_segment, take_next_group, refresh, advance_cycle, ...), and the
  real on-demand status envelope ({status, data: {state, service}})
- app.py:199 / :144 / :607-619 line citations and
  web_interface/blueprints/api_v3.py (now a package) replaced with file and
  function names in ADVANCED_FEATURES, CONFIG_DEBUGGING,
  PLUGIN_ARCHITECTURE_SPEC, PLUGIN_QUICK_REFERENCE,
  PLUGIN_CONFIGURATION_TABS, TROUBLESHOOTING and web_interface/README
- CONFIG_DEBUGGING: partial /config/main saves change only sent keys; use
  /config/raw/main to replace the file; describe where validation runs
- TROUBLESHOOTING: clear_cache.py needs --clear-all (no args only prints
  usage)

* fix(scripts): verify the web interface that actually ships, on port 5000

verify_installation.sh failed every healthy install: it required the
long-removed web_interface_v2.py and looked for a listener on port 5001,
while the web interface binds 5000 (web_interface/start.py). It now
checks the files ledmatrix-web.service runs (start_web_conditionally.py,
web_interface/start.py, app.py) and port 5000. verify_web_ui.sh had the
same 5001 port in its listen check, HTTP probe and printed URLs.

Port matches are anchored so :50001 no longer counts as :5000.

* docs(plugins): one display-size contract: display_manager.width/height

CLAUDE.md (#580) says to read display_manager.width/height because
matrix is None when hardware init fails; the development guide, the
safety-harness doc and two DisplayManager docstrings still recommended
matrix.width/height. The bundled starlark-apps plugin read matrix.width
unguarded, so its magnify recommendation and frame scaling raised in
fallback mode (e.g. after the Pi 5 hardware refusal).

* fix(install): make install_service.sh --help print usage instead of installing

install_service.sh parsed no arguments, so `sudo ./scripts/install/
install_service.sh --help` (presented as harmless in MIGRATION_GUIDE.md)
rewrote ledmatrix.service, ledmatrix-web.service and both update-verify
units and enabled/started them. It now handles -h/--help (usage, exit 0,
no changes) and rejects any other argument with exit 2 before doing
anything. Running it with no arguments, as first_time_install.sh does,
is unchanged.

* docs(scroll): describe the fixed-step model and document frame_hold

Since #545 a crisp speed from scroll_config.configure() makes the helper
advance a fixed whole-pixel step per presented frame with no clock, and the
display manager's frame hold is part of the speed. The docs still described
the removed wall-clock model:

- scroll_config's module and configure() docstrings said speed is applied
  in time-based mode and that omitting the hold "falls back to fractional
  pixels"; omitting it actually runs the scroll frame_hold times too fast.
- SCROLL_PERFORMANCE.md said ScrollHelper accumulates elapsed time in both
  modes, and read a 20 ms stats median as missed refreshes although that
  is a healthy 50 px/s (hold 2) scroll. It now explains the fixed step,
  the hold-dependent healthy median, that target_fps plays no part, and
  that a hand-added scroll_pixels_per_second loses to a schema-default pair.
- PLUGIN_API_REFERENCE.md documented set_scrolling_state(is_scrolling)
  without frame_hold; it now documents the parameter (core 3.4.0) with a
  configure() + set_scrolling_state example.
- update_scroll_position/set_scroll_speed and set_scrolling_state
  docstrings say the same.

* docs(config): mark target_fps legacy; describe what Vegas scroll_delay does

- General tab "Scroll Frame Rate" (target_fps) is labelled legacy: after
  the sports_scroll fix nothing in core scrolling reads it. The field and
  its API validation stay so saved configs and plugins that read
  global_config['target_fps'] keep working. CONFIG_REFERENCE says the same.
- Vegas frame_based_scrolling/scroll_delay were described as frame-count
  stepping at ~50 FPS. Neither steps nor sets a frame rate: frame-based
  mode converts the speed to px per scroll_delay, clamps it to 0.1-5, and
  still advances by elapsed time, so the applied speed is
  clamp(scroll_speed * scroll_delay, 0.1, 5) / scroll_delay px/s. The
  config comments, render_pipeline comment and CONFIG_REFERENCE rows now
  say so. No behaviour change.

* docs(deps): describe how plugin dependencies are really installed

The guides said the web service runs as root, that installs pick --user
from os.geteuid(), and quoted a warning and a
PluginManager._install_plugin_dependencies() method that don't exist. The
web unit runs as the installing user; store installs go through
install_requirements_file() and sudo safe_pip_install.sh (root), with a
user-level fallback that says so, and load-time installs run in the
display service's own (root) interpreter.

Manual paths now use the configured plugins directory (plugin-repos/ by
default) instead of plugins/, which store installs no longer use, and
install_plugin_dependencies.sh is described as scanning that directory.

* fix(update): count local changes one way for the preflight and the pull

The automatic update's preflight ignored mode-only changes and anything
whose status line contained plugins/ or plugin-repos/, then promised
"Automatic updates will not stash your changes". perform_core_update
used plain git status (modes count) and ignored only 'plugins/', then
ran 'git stash push -- :!plugins', which nothing ever pops. So an edit
to a bundled plugin under plugin-repos/, or the installer's chmods on
tracked scripts, passed the preflight and was stashed away for good.

- auto_update.local_changes() is the one predicate both use:
  core.fileMode=false, porcelain -z, and plugins/ and plugin-repos/
  excluded by leading folder rather than substring (a core file under
  web_interface/static/v3/js/plugins/ now counts).
- Update Code's explicit stash leaves out both plugin folders; the
  pull's --autostash carries their edits and mode changes across and
  reapplies them.
- The automatic updater calls perform_core_update(stash_local_changes=
  False), which refuses instead of stashing edits that appeared after
  the preflight; update_core reports that as 'blocked'.

* fix(scripts): diagnostics follow the web autostart default and api_v3 package

#556 made a missing web_display_autostart mean "start" (only an explicit
false/off keeps the web interface down), but the diagnostics still said
otherwise: diagnose_web_ui.sh reported a missing key as "defaults to
false", diagnose_web_interface.sh said the web interface "will not start
unless this is set to true" and recommended enabling it, and
debug_web_manual.py printed False. Troubleshooting a down web UI pointed
users at a non-cause.

Both shell scripts now evaluate the setting with the launcher's own
autostart_enabled() (inline fallback if it cannot be imported) and report
on / off / not set (on) / unparseable config; debug_web_manual.py uses
the same function. They also check web_interface/blueprints/api_v3/
__init__.py: api_v3.py became a package in #553, so every healthy
checkout was reported as missing a file.

install_service.sh installs and starts ledmatrix, ledmatrix-web and the
update-verify units, not only ledmatrix.service (systemd/README.md,

* fix(display): size the preview after orientation and pixel mappers

display_geometry.physical_size claimed to give DisplayManager's answer but
only computed cols*chain x rows*parallel. RGBMatrix.width/height are measured
after the library's pixel mappers, so a Rotate:90 / orientation 90 chain
previewed 128x32 for a 32x128 panel and a U-mapper chain of four 256x32 for
128x64.

Model the built-in mappers' size effect as the pinned lib/pixel-mapper.cc
does (Rotate, U-mapper, V-mapper, StackToRow, Remap; Mirror and unknown
names leave it alone), and move the orientation composition here so
DisplayManager and the preview share it. The module docstring no longer
claims the sync handshake uses it; that imports only DEFAULT_CHAIN_LENGTH.

Audit finding F18.

* fix(display): refuse settings the rgbmatrix library aborts on, on every board

The library answers several settings with a NULL matrix or abort() rather
than an error, so the display service crash-looped (Restart=on-failure)
instead of reaching fallback mode: rows above 64, chain_length above 255
(uint8_t binding setter, documented as "no upper limit"), a misspelled
hardware_mapping, and parallel 2-3 on a single-output mapping, reachable
from the Display form on the default adafruit-hat(-pwm) mapping. #586 only
guarded the Pi 5 subset.

- src/matrix_support.py holds the rules for every board (Options::Validate
  ranges, binding integer types, mapping names and outputs from
  lib/hardware-mapping.c) plus the Pi 5 ones, and is the one source of the
  API's numeric ranges.
- DisplayManager checks them before building options and raises
  MatrixSettingsRefused, so a hand-edited config falls back with a logged,
  reported reason. Emulator mode only warns.
- The config API refuses them with a 400 naming the setting; combinations
  are checked against stored values but reported only when the request
  sets a field involved.
- The hardware status file gains "cause" (settings/library/forced). The
  fallback log and Display banner give the Pi 5 rebuild hint only for a
  library failure instead of rebuild + gpio_slowdown advice for every
  failure; one Pi 5 slowdown recommendation (1-3, start at 1).
- The Display form offers classic/classic-pi1 and orientation 90/270 and
  renders any other stored mapping selected with a warning, so an
  unrelated save no longer rewrites them; the API accepts 90/270.

Audit findings F03, F16, F19, F21.

* docs(display): library limits, template defaults and Pi 5 slowdown

- rows 8-64, chain_length 1-255, parallel limited by the mapping's outputs,
  classic/classic-pi1 mappings and orientation 90/270 documented.
- Defaults are the config.template.json values: config migration adds
  missing keys from the template, so the listed "code defaults" never
  applied.
- One Raspberry Pi 5 gpio_slowdown recommendation: 1-3 in PIO mode,
  starting at 1.
- Troubleshooting describes the refused-settings fallback, and CHANGELOG
  corrects the Unreleased "no upper limit" entry.

* fix(scripts): scroll_speeds.py opens the panel with the service's options

--measure and --demo built RGBMatrixOptions from a private copy of the
display service's builder that had drifted: gpio_slowdown came from
display.hardware (default 2) instead of display.runtime (default 3), and
rp1_rio, panel_type, disable_hardware_pulsing, inverse_colors,
pixel_mapper_config and orientation were skipped, with different defaults
(hardware_mapping "regular", pwm_bits 11). A panel needing a high slowdown
was measured -- or garbled -- in a setup the service never drives.

The option filling in DisplayManager._setup_matrix moves, unchanged, into
DisplayManager.apply_matrix_options(options, config), which _setup_matrix
calls and the script reuses (overriding only limit_refresh_rate_hz for
--measure). The script now loads the whole config rather than the hardware
block. Tests pin the script's options to the service's attribute for
attribute.

* fix(scripts): scroll_speeds.py recommends keys the resolver honours

The ladder ended by telling users to set
display_options.scroll_pixels_per_second. scroll_config ranks that key
below the scroll_speed + scroll_delay pair, deliberately, and several
plugin schemas default the pair into config, so the advised key was
silently ignored (a schema-default 1/0.02 pair plus an advised 66 still
resolved to 50 px/s).

The advice is now the pair that selects the crisp speed exactly
(pixels_per_frame every frame_hold/refresh seconds), explains that the
pair outranks scroll_pixels_per_second, and gives the scoreboards'
per-league scroll_settings.scroll_speed (px/s) form. Tests resolve the
printed pair over a schema-default pair and check it lands on the
advertised speed and hold.

* docs: withdraw the target_fps claim for sports_scroll; fix the Vegas speed formula

- SPORTS_UNIFICATION.md still presented honouring global target_fps as
  sports_scroll's added behaviour and its one user-visible gain; note that
  it was withdrawn because it had become a speed multiplier.
- ADVANCED_FEATURES.md gave Vegas scrolling as
  (scroll_speed / target_fps) * elapsed; the real rule is scroll_speed px/s
  by elapsed time, through a 0.1-5 px per scroll_delay clamp when
  frame_based_scrolling is on.

* fix(dev): link-github links plugins from the ledmatrix-plugins monorepo

link-github <name> cloned https://github.com/ChuckBuilds/ledmatrix-<name>.git,
and those per-plugin repositories no longer exist: official plugins are
directories in the ledmatrix-plugins monorepo. It now clones (or pulls) the
monorepo once into the dev directory, finds plugins/<name>,
plugins/ledmatrix-<name> or the plugin whose manifest id is <name>, and
links it under its manifest id. With an explicit repo URL it still links a
single-repository plugin as before.

dev_plugins.json: github_user is honoured again (monorepo owner, e.g. a
fork), plus plugins_repo and plugins_branch; github_pattern, which was
documented but never read, is dropped and warned about. Ships
dev_plugins.json.example and git-ignores dev_plugins.json, both of which
the guide promised. Reading JSON falls back to python3 when jq is missing
(get_plugin_id silently returned nothing without jq).

update/status/list find the git checkout above a monorepo plugin
directory (its .git is not in the plugin dir), and update pulls a shared
checkout once. status no longer exits 1 when nothing is broken.

Docs: PLUGIN_DEVELOPMENT_GUIDE (quick start, link-github, configuration,
workflow, store integration, hello-world link, submission), and the
nonexistent scripts/git-hooks/pre-push-plugin-version and
scripts/bump_plugin_version.py replaced with the real rule: bump the
manifest version and run update_registry.py. scripts/dev/README.md and
CLAUDE.md updated to match.

workspace file opens LEDMatrix plus ../ledmatrix-plugins.

scripts/fix_perms/README.md listed cache directories
fix_cache_permissions.sh never touches and a 'ledmatrix' service user
that doesn't exist (also in scripts/install/README.md); adds
safe_pip_install.sh. install/README: install_service.sh installs the web
and update-verify units too.

* fix(update): keep the rollback's pip retries inside the unit time limit

The health check reinstalled the previous requirements by trying the
next bash path after any failure, including a 600 s pip timeout. Two
files, two paths: up to 40 minutes of pip alone, while systemd stops
ledmatrix-update-verify.service at TimeoutStartSec=30min -- killing the
rollback half-way and leaving the update 'verifying' until the web UI
calls it lost.

- Like permission_utils.install_requirements_file, only a sudo refusal
  moves on to the next bash; a pip that ran and failed or timed out is
  not repeated. The refusal wording is one list
  (permission_utils.SUDO_REFUSAL_PHRASES), mirrored in the stdlib-only
  verifier and pinned equal by a test.
- All reinstalls in one rollback share a 600 s budget.
- WORST_CASE_SECONDS adds up every timeout on the longest path (27.5
  min); a test holds it under the unit's TimeoutStartSec and that under
  the web UI's VERIFY_LOST_SECONDS.

* fix(plugins): prepare plugin configs one way for load, saves, GET, hot reload and dev tools

Plugin config was prepared differently depending on how it arrived:

- JSON POST /plugins/config built a partial body on schema defaults, so
  {"enabled": true} reset every other setting of the plugin. It now merges
  onto the stored section first, as the form path already did.
- Legacy-boolean normalization (#588) ran only at load: GET /plugins/config
  returned the raw boolean, posting it back failed validation, and hot
  reload handed plugins the raw section (a legacy dynamic_duration: true
  came back as a boolean). schema_manager.prepare_plugin_config (normalize,
  then defaults) is now used by PluginManager.load_plugin, both save paths,
  GET, the save notifications and DisplayController's hot-reload callback.
- The JSON save's filter kept only enabled/display_duration/live_priority
  and dropped a submitted skin, skin_options or vegas_* tuning key. There
  is now one core-owned per-plugin list, schema_manager.CORE_PLUGIN_PROPERTIES,
  used by validation and by the save filter; PluginManager's
  CORE_OWNED_CONFIG_KEYS is its vegas subset.
- Plugin sections posted to /config/main were stored verbatim, including
  values /plugins/config rejects. They now go through the same preparation
  (_prepare_plugin_config_for_save, extracted from save_plugin_config), and
  a failing section rejects the whole save before anything is written.
- dev_server read only top-level defaults and let a schema enabled:false
  win; build_full_config shallow-merged overrides, dropping sibling
  defaults; the harness extracted defaults differently from the device.
  loading.build_config now uses the device's extraction and preparation,
  and dev_server, check_plugin, render_plugin and the harness all use it.

On Linux Repo.publish() commits with -a, which recorded scripts/run.sh

then brought in the same mode the installer chmod had made locally, so
installer_chmod saw no mode change left to check. The updater was fine:
with the upstream commit at 100755 the --autostash carries the device's
chmod across. Verified under Linux (WSL, git 2.43): the old helper fails
exactly as CI did, the fixed one passes all 63 tests in the file.

ChuckandClaude Opus 5 1d51efe4c7 fix(backup): restore over existing files on hosts without os.chown (#592)
_copy_file() replaces each restored file and then carries the previous
owner across with os.chown. On Windows os.chown does not exist and
st_uid/st_gid are 0 rather than absent, so the ownership branch always
ran and raised AttributeError. That is not an OSError, so it escaped
every per-section handler in restore_backup(): a restore over any
existing config aborted at config.json and restored nothing.

Skip the ownership step where os.chown is missing, as
auto_update_setup.py already does. No change on POSIX.

test_restore_over_a_file_the_user_cannot_write simulates root-owned
files with chmod 0o444; on Windows that sets the read-only attribute,
which blocks any rename over the file, so it is skipped there. The
modes the app writes (0o644/0o640/0o600) replace fine on Windows.

ChuckandClaude Opus 5 7ae614aa35 fix(sports): recover from ESPN rejecting scoreboard date ranges (#591)
* fix(sports): recover from ESPN rejecting scoreboard date ranges

Since 2026-09-15 ESPN's site API answers `dates=YYYYMMDD-YYYYMMDD` with
400 "Failed to get events endpoint." for every sport. Single days, months
(`YYYYMM`) and season years still work. Every season and weeks-window fetch
in core failed, including the background service the scoreboards submit
their season schedules to.

src/common/espn_dates.py re-asks a rejected range as whole-month chunks
plus the leftover edge days, which tile the window exactly (a season is
8 requests, not 213). A month that comes back with exactly 500 events is
truncated (college baseball's March) and is re-asked day by day.

It also clamps `limit` to 500: above that ESPN truncates silently, e.g.
college football returns 25 of 68 games for one Saturday at limit=1000.

BackgroundDataService recovers rejected ranges on the worker thread and
advertises `handles_espn_date_ranges` so plugins can tell whether to hand
it a range. SportsCore, sports_shared, ESPNDataSource and APIHelper route
through the helper or the clamped limit.

* fix(sports): stop re-sending ESPN date ranges once one is rejected

Live scoreboards refresh every 30 seconds, and each refresh sent the range
first, got the 400, then fetched the chunks: three requests where one used
to do. After a rejection, ranges now go straight to chunks for six hours,
then the range is tried again so the workaround retires itself if ESPN
reverts. A single-day 400 does not set the memo, and when every chunk fails
the range request supplies the error without the chunks being fetched a
second time. Per-fetch chunk logging drops to debug; the rejection itself
stays a warning.

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

* fix(sports): clamp limit only on ESPN scoreboard submissions

The background service is generic, and limit above 500 only truncates
scoreboards. /teams needs limit=1000 (college football has 762 teams and
limit=500 returns 500), so a teams submission must keep its limit.

ChuckandClaude Opus 5 2082665252 fix(config): load config_secrets.json on hosts without os.geteuid (#590)
ensure_shared_group_ownership() - the chgrp self-heal ConfigManager runs
before reading config_secrets.json (#416) - looked up os.geteuid
unguarded. That name does not exist on Windows, and the AttributeError
is not an OSError, so it escaped the helper's best-effort handling and
every except clause in load_config(). Any Windows checkout with a
config/config_secrets.json got a ConfigError from every config load and
could not import web_interface.app.

That is what made test_update_all_plugins.py error at setup: its client
fixture imports web_interface.app. It was not state leaked between test
files - the trigger is whether the checkout has a secrets file.

ChuckandClaude Opus 5 f9b3d6ae52 fix(web): accept every panel size and row address type the rgbmatrix library does (#586)
* fix(web): accept every panel size and row address type the rgbmatrix library does

The Display form capped columns at 128 and chain length at 24, and its
submit handler (fixInvalidNumberInputs) rewrote anything larger to the cap,
so wide panels and long chains silently saved as the wrong size. The config
API checked none of the hardware numbers, so values the library rejects (odd
rows, parallel 4, PWM dither bits 3) saved and the matrix then refused to
start.

- Form limits now match the pinned library: rows even 8-64, cols >= 16 and
  chain_length >= 1 with no upper bound, parallel 1-3, PWM dither bits 0-2,
  PWM LSB nanoseconds 50-3000.
- save_main_config rejects out-of-range rows, cols, chain_length, parallel,
  brightness, scan_mode, pwm_bits, pwm_dither_bits, pwm_lsb_nanoseconds and
  gpio_slowdown with a 400.
- A stored gpio_slowdown or pwm_dither_bits of 0 renders as 0 instead of the
  default, so saving the tab no longer overwrites it.
- Row Address Type offers 5 (SM5368 / B707 row shift register). Verified on a
  Waveshare 96x48 V2 (24S-A1) on a Pi 4 with the Adafruit Triple LED Matrix
  Bonnet: rows 48, cols 96, row address type 5, BGR, GPIO slowdown 8.
- Help text and docs: FM6124-family panels use Panel Type Standard; on a Pi 5
  the library supports only row address types 0 and 2.

No change to the rpi-rgb-led-matrix submodule.

* fix(web): drop the rows cap and document every display setting accurately

Rows: no upper limit in the form or the API. Still even and at least 8. The
current rgbmatrix library rejects more than 64 per panel, so a larger value
saves but the matrix won't start; the help tip, README, config reference and
troubleshooting section all say so, and nothing here needs changing if the
library lifts the limit.

limit_refresh_rate_hz: the form accepts 0 (the library's "no cap"), a stored
0 no longer renders and re-saves as 120, and the API rejects negatives.

pwm_dither_bits stays 0-2: the library rejects 3 and 4, so the old form's
0-4 only ever let users save a config the display couldn't start with.

Docs and help tips, checked against the pinned library and its README:
- panel_type and rp1_rio get README entries
- show_refresh_rate prints to stdout; it never drew on the panel
- dither bits raise the refresh rate; the tip said they lowered it
- scan_mode is about interlacing at low refresh, not wrong colours
- disable_hardware_pulsing: hardware pulsing needs OE on GPIO 18 and the
  onboard sound driver off; software timing makes rows flash brighter
- gpio_slowdown guidance agrees between the README and the UI
- all 22 multiplexing values listed; every numeric setting states its range
- troubleshooting for a blank panel after a settings change, jumping rows
  and brightness flashes

* fix(web): reject true and 5.5 for row_address_type and multiplexing

Both still went straight through int(), so a JSON true saved as 1 and 5.5

fields. Review feedback on #586.

Also: the RP1 Backend tooltip said it is ignored on Pi 3/4 (it is ignored
on every model but the Pi 5), and the README gave the dynamic-duration
default cap as 90s; the code default is 180s.

* feat: refuse matrix settings a Raspberry Pi 5 can't drive

On a Pi 5 the pinned rgbmatrix library drives the panel through the RP1
chip, and that path supports only row address types 0 and 2, parallel 1-3
and the regular / regular-pi1 / classic / adafruit-hat(-pwm) mappings
(Rp1PioConfigSupported in lib/rp1/rp1_pio_backend.cc). For anything else
CreateFromOptions returns NULL; the Python binding doesn't check, so the
display process crashed on its first call into the matrix and systemd
restarted it into the same crash every 10 seconds.

- src/pi5_matrix_support.py: the rule and Pi 5 detection, matching the
  library's /proc/device-tree/model check
- DisplayManager raises before creating the matrix, so it is a logged init
  failure (reported by /api/v3/hardware/status) and fallback mode
- the config API rejects those settings on a Pi 5 when a request sets
  row_address_type, parallel or hardware_mapping
- the Display form offers only row address types 0 and 2 on a Pi 5, and
  warns when a stored value can't be used
- CLAUDE.md: re-check the rule whenever the submodule is bumped

Review feedback on #586.

ChuckandClaude Opus 5 9616a5a054 fix(web): auto_update and other core settings are not orphaned plugins (#589)
v3.4.0 shows "Plugin Config Warning - In config but not installed:
auto_update. Reinstall via the Plugin Store, or remove these entries from
config.json." auto_update is the core weekly-update setting from #581.
Reconciliation treated every top-level dict not in its private
_SYSTEM_CONFIG_KEYS list as a plugin id, and #581 could not know to extend
that list.

- Move core top-level keys into src/core_config_keys.py (CORE_CONFIG_KEYS)
  and use it in reconciliation. Tests fail if a config.template.json key or
  a key written by the general-settings save is missing from it.
- A secrets-file key only counts as a non-plugin when no installed plugin
  has that id. Plugin secrets are namespaced by id, so installed plugins
  with secrets were reported as missing from config on every run.
- still_unresolved() drops "not on disk" findings whose id is no longer a
  plugin entry in config, so a stored verdict clears without a restart.
- A plugin whose id is a core key is skipped with a warning, and the fix
  never writes a plugin stub over or in place of a core setting.

ChuckandClaude Opus 5 c200b5837d fix(plugins): normalize legacy boolean settings before schema validation (#588)
The news plugin's schema turned global.dynamic_duration from a boolean
into an {enabled, min_duration_seconds, ...} object. Installs that have
not saved the news settings since still hold `true`, so every start
logged "Plugin news config does not match its schema (loading anyway):
Field 'global.dynamic_duration': Expected type object, got bool" and
flagged news degraded.

The settings form already reads such a boolean as {"enabled": <bool>}
(render_nested_section in plugin_config.html) and the next save writes
the object. The loader did not. It now applies the same rule before
merging schema defaults and validating, so the defaults fill in the rest
of the object and the plugin receives it in the new shape.

The rule lives in schema_manager.legacy_bool_as_object /
normalize_legacy_booleans. It applies at any depth of nested objects
but not inside arrays, matching the form, and only to a real bool under
an object-typed property with an `enabled` child. Every other mismatch
still warns. A parity test renders the template macro against the helper
so the two cannot drift.

Nothing is written to config.json at load: the normalization is in
memory, and the next save of the plugin's settings persists the object.

ChuckandClaude Opus 5 9f2743471c fix(web): update-all skips Starlark apps and no longer misses plugins (#587)
* fix(web): update-all skips Starlark apps and no longer misses plugins

Check & Update All posted every entry from /plugins/installed to
POST /plugins/update, including the virtual starlark:<app_id> entries
that list installed Starlark apps. The store manager cannot find those,
so each answered 500 "plugin not found". Update-all now sends only
plugin ids (install_manager.js, and the older app-shell.js copy), and the
route answers a starlark: id with a 400 saying it is a Starlark app.

A request that got no HTTP answer was recorded as failed and never sent
again. On a device, a web-service restart mid-run killed the in-flight
request and refused the next one, stock-news, which was left on 2.6.2
with 2.8.0 available. Such requests are now re-sent with backoff
(about 30s) before being reported as failed. HTTP error answers are not
retried.

Tests: test/js/unit/test_update_all.js (run from pytest via
test/web_interface/test_update_all_plugins.py so CI covers it) and the
route contract for starlark: ids.

* refactor(web): walk update-all retry delays without indexed lookup

Codacy's ESLint security/detect-object-injection rule flagged
retryDelays[attempt] as a High issue. The index was a bounded loop
counter over a fixed array, but shifting a per-plugin copy of the
schedule gives the same backoff without the pattern. No behaviour
change: test/js/unit/test_update_all.js (21) and
test/web_interface/test_update_all_plugins.py (7) pass unchanged.

ChuckandClaude Opus 5 fddb0e06db feat(web): honour x-display: hidden in plugin settings (#585)
* feat(web): honour x-display: hidden in plugin settings

Plugins keep deprecated and internal keys declared so stored configs keep
validating (weather api_key/radar_zoom, countdown's auto-generated row id),
but the settings form drew them as live controls.

A property marked "x-display": "hidden" -- or an object whose children are
all hidden -- now gets no control at any depth: top level, nested sections,
Advanced Settings (not counted either), array-table columns and the row
editor. A hidden top-level key is not reported in __rendered_section.

Saving never changes a hidden value. Plain and nested fields aren't posted,
so the save's deep merge keeps them; _set_missing_booleans_to_false skips
hidden booleans at every depth. A posted array row replaces the stored item,
so hidden row properties are carried as JSON-encoded hidden inputs and
decoded exactly on save (an id "1" stays a string). New rows get none.
JSON API saves are unchanged.

* refactor(web): read hidden row keys without dynamic property access

Build the set of x-display: hidden item properties once and look values up
through Object.entries, instead of indexing objects by a variable key on
the lines this branch added (Codacy: object injection sink, 6 warnings).
Behaviour is unchanged.

ChuckandClaude Opus 5 8360220809 feat(common): sports_helpers — the helpers all nine scoreboards carry identical copies of (#583)
* feat(common): sports_helpers, the helpers all nine scoreboards copy verbatim

Add src/common/sports_helpers.py: the helpers the scoreboard plugins'
sports.py carry byte-identical copies of (docstring-stripped AST, checked at
ledmatrix-plugins f09bff2), so a later plugins PR can delete its copies once
it floors on the core release that ships this.

- Free functions: clamp_window, clamp_seconds, logo_needs_refresh (lazy
  src.logo_downloader import, as in the plugins), spread_weighted_order,
  MIN_WINDOW_DAYS / MAX_WINDOW_DAYS. All nine plugins.
- SportsHelpersMixin (no __init__, stateless): _mode_customization,
  _setting_int, _reset_dwell_on_reentry, _next_switch_index,
  _spread_weighted_order (all nine), _odds_color and
  _upcoming_date_and_time_text (all but ufc), plus the _favorite_key seam
  from base_classes core.py for later phases.

A new module rather than more methods on sports_shared: a plugin that
deletes a copy and relies on an existing module having grown the method
fails at runtime with AttributeError on an older core, which neither the
loader nor check_min_core_version.py can see; a missing module fails at load.

Tests: behaviour for every helper, a derived host contract, and a parity
test that AST-compares every body against every plugin copy when
LEDMATRIX_PLUGINS points at a checkout (skipped otherwise).
test_common_is_hardware_free.py imports src.common and every sports_* module
with rgbmatrix blocked and scans src/common for module-level imports of
src.base_classes, src.display_manager and src.plugin_system (no existing
violations).

Nothing in core imports the new module; no behaviour change. CHANGELOG
Unreleased entry and a converging note in docs/SPORTS_UNIFICATION.md.
__version__ is not bumped.

* fix(common): address review on sports_helpers and the hardware-free test

- SportsHelpersMixin docstring and CHANGELOG: constructor-free, but it keeps
  lazy state on its host (_reset_dwell_on_reentry, _next_switch_index).
- test_common_is_hardware_free: the runtime check now filters every
  FORBIDDEN package, src.plugin_system included; the AST scan resolves
  relative imports against src.common, so `from .. import plugin_system`
  and `from ..plugin_system import x` are caught. Guard tests for both.
- Parity skip reason names the CI guard that runs the same comparison:
  ledmatrix-plugins scripts/check_sports_helpers_parity.py (#495).
- _odds_color: line-level pylint disable for a not-callable false positive
  (getter is None-checked); the AST is unchanged, parity still passes.
