ChuckandClaude Opus 5.5 8136a2d525 fix(ipc): a plugin reload no longer freezes the panel during Vegas (#723)
A plugin.reload no longer freezes the panel during Vegas: the old instance is torn down and the new one loaded off the render thread (frame gap 3017 ms -> 9 ms in the ledpi reproduction). A failed or timed-out teardown stops the reload with a restart hint instead of loading over stale modules or tearing down an instance still in use.

ChuckandClaude Opus 5.5 85be4bf25d fix(display): end the scroll before the schedule-off blank and WiFi notice (#721)
The schedule-off blank and the WiFi notice are drawn by the display controller, not dispatched to a plugin, so #716's handover never reached them. Drawn while the last scroll's state was still set, the blank went out with the ticker's lagging rows on a scan-compensated panel and stayed up for its 60 s dwell, and the notice's redraws (which #712 now shows over a running scroller or Vegas) were timed as 0.5-1 s freezes and logged as a mid-scroll Render stall. The controller now calls set_scrolling_state(False) before drawing either; a scroller that resumes sets the state again on its next frame.

Control socket stage 2: the render thread wakes for queued commands (static screens ~1 ms, Vegas within one frame), brightness.set, and plugin.reload after a store update, with mailbox/restart fallbacks. Rig checks listed in the PR body are still to run.

ChuckandClaude Opus 5.5 34be83d595 fix(display): end the scroll state at scroller-to-static handovers (#716)
A static plugin screen that follows a scroller no longer starts with the ticker's lagging rows on scan-compensated panels, and the 1 Hz loop's second frame is no longer recorded as a ~1 s mid-scroll freeze / Render stall. The display controller calls DisplayManager.end_scroll_for_static_screen() before a static screen's first display() (clears the scan history; _scan_segments passes its frames through in one swap) and set_scrolling_state(False) after it; the scroller's hold stays until then, so late-frame counts are unchanged. A screen's first frame is tagged 'handover': gaps of 250 ms or more before it go to the additive handover_freezes (frame_soak prints 'Handover gaps'), not freezes. The display thread is named display-<plugin id>. The WiFi notice and the schedule-off blank are not covered yet (docs list them as a follow-up).

ledpi A B B A soak (20 min each, --preview): main 0.118% / 0.113% late with 6 / 3 freezes; with this and #717 0.107% / 0.104% late, 0 freezes.

ChuckandClaude Opus 5.5 41db488c73 fix(display): schedule windows end at the end time; on-demand ending in off hours blanks at once (#714)
Schedule and dim windows are half-open [start, end): on from the start time, off at exactly the end time, whatever second the check runs. An on-demand session that ends in scheduled-off hours (expiry or stop) clears the once-a-minute schedule gate, so the panel blanks within about a second. Golden: schedule; two test_display_pending_changes.py tests now say end_time 23:00.

Merged with #712 and #713: with all three in, docs/RUN_LOOP_REDESIGN.md's 'may be wrong' list is empty, so that section now records that all six items are fixed and by which PR.

ChuckandClaude Opus 5.5 77e0ea91ae fix(display): live games take over within a second, and straight from Vegas (#713)
A game that goes live takes over within about a second (_check_live_takeover in the frame loops and the dwell sleep, throttled to 1 s, never during on-demand, scheduled-off, live_in_ticker or an already-live screen); an interrupted Vegas iteration switches straight to the game; has_live_content() is asked once per plugin per scan. Goldens: live_priority, vegas.

Merged with #712: after an interrupted Vegas iteration the WiFi-notice check runs before the live switch (WiFi outranks live). Adds test/test_run_loop_wifi_and_live.py, pinning that a notice and a game arriving during the same screen (1 Hz, 125 Hz, Vegas) show the notice first, then the game, and neither while scheduled off.

A WiFi notice preempts the current screen within about a second (frame loops, post-loop check, make-up dwell), and an interrupted Vegas iteration that yielded for a notice ends the pass so the notice shows next.

ChuckandClaude Opus 5.5 9edeb6da14 fix(display): a raising display() counts as a circuit-breaker failure (#707)
The first-frame dispatch (_dispatch_first_frame) now asks PluginExecutor.execute_display() to re-raise (raise_errors=True) and records a raise inside the executor as a breaker failure, with the original exception as last_error, instead of a success. The screen is still an empty pass and rotation is unchanged; a hung display() is still recorded once, as a hang. The run-loop golden trace plugin_error.json is regenerated (crashy now records health failures and is skipped by the breaker), and behaviour 7 is dropped from docs/RUN_LOOP_REDESIGN.md.

The display serves a control socket (/run/ledmatrix/control.sock) carrying versioned JSON commands, one per line, each answered. Stage 1 covers on-demand start, stop and status; commands are queued on the socket thread and applied on the render thread through the mailbox's own handler, and the web interface falls back to the file mailbox when the socket is unavailable.

ChuckandClaude Opus 5.5 7f06cc9c3b feat(vegas): keep live games in the ticker by default (#699)
* perf(timing): say which render-thread work a late frame followed

The soak already says how often a moving frame reached the panel late, but
not what the render thread was doing just before it. Vegas does two kinds of
work there between frames -- building its strip (compose, extend) and, with
live elements, patching changed pixels into it -- and deciding whether either
is affordable needs their own numbers.

- FrameTimingRecorder.note_op(kind, nbytes) tags the next presented frame.
  Totals gain op_frames, late_op_frames, op_freezes and op_bytes per kind;
  aggregate() still takes frames without ops. The file schema is unchanged.
- Vegas tags compose and every strip extension (with the bytes it copied).
- frame_soak prints an "after work" table: frames, late %, freezes and MB
  moved per kind, only when something tagged its work.
- render_bench gains --strip-screens (Vegas-sized strips), --patch-bytes /
  --patch-every / --patch-where (in-place column writes, as a live element
  update does) and --extend-every-screens / --extend-width (append + trim on
  a fixed cadence that holds the strip's width).

No runtime behaviour changes: this is the measurement gate for live Vegas
elements.

* docs(changelog): note the frame-op attribution and bench modes

* perf(scroll): build the strip's PIL image only when something reads it

Every Vegas strip extension rebuilt ScrollHelper.cached_image from
cached_array in full, twice (append, then trim), on the render thread:
Image.fromarray is 1.7ms for an 8,000px strip and 3.8ms for 20,000px on a
Pi 4 (measured on ledpi), about two thirds of an extension's render-thread
cost. Nothing on the frame path reads the image's pixels; every frame is cut
from the array.

cached_image is now a property. append_content and drop_scrolled_prefix
defer it; the first read builds it from the array it started with and keeps
it only if the strip has not changed meanwhile, so a sync push racing an
extension cannot leave a stale image cached. Assigning cached_image stores
exactly what was assigned, as before. has_strip() says whether there is a
strip without building its image; the helper's frame path, Vegas and the
adapter's scroll-cache invalidation use it. The strip is also no longer held
in memory twice.

In Vegas the image is now built only by a multi-display sync push.

* feat(vegas): live elements -- a plugin API for content that changes while it scrolls

Vegas bakes each plugin's pictures into one strip, so a card already on its
way across the panel keeps what it showed when it was drawn. This adds the
API and bookkeeping for content that can be updated in place; the worker
that redraws and swaps it follows separately. No shipped plugin implements
the hook yet, so nothing changes for users.

Plugin API (core 3.8.0), all no-ops by default:
- BasePlugin.get_vegas_elements() -> [VegasElement(key, image, version,
  live, refresh_hz)]: named, fixed-width pieces of Vegas content.
- BasePlugin.redraw_vegas_element(key, width, height, at): a lock-free
  redraw for content that changes with time.
- BasePlugin.notify_vegas_data_changed(): data that lands outside update().
- src/plugin_system/vegas_elements.py (VegasElement, re-exported from
  base_plugin).

Core:
- PluginAdapter asks a plugin that implements the hook for elements on the
  background fetch only (under its lock, on its own canvas); every other
  path keeps get_vegas_content(). Live elements are pinned (padded with
  content_padding, never trimmed), tagged with their key, digest and data
  epoch in Image.info so the existing cache and group plumbing carry them
  unchanged, and untagged if a width budget crops them.
- RenderPipeline records where each live element lands (ElementRecord), in
  absolute strip columns a trim does not move; the block-start arithmetic
  is shared with the STATIC markers.
- PluginManager update listeners (add/remove_update_listener,
  notify_data_changed): told the moment update() completes, not at the
  next ~4s Vegas poll. The coordinator uses one to move each plugin's data
  epoch on.
- vegas_scroll.live_refresh (kill switch), live_max_hz, live_min_interval,
  live_lead_screens; per-plugin core-owned vegas_live. Live elements are
  off under multi-display sync, in swap mode and with offscreen_prefetch off.
- scripts/check_plugin.py checks the element contract
  (src/plugin_system/testing/vegas.py); test/fixtures/plugins/vegas-live-stub
  is a working example.

* feat(vegas): live elements update in place while they scroll

One background worker (src/vegas_mode/live_worker.py) redraws a plugin's
live elements when its data epoch moves on (update listener) or on their
refresh_hz, nearest the screen first, and hands changed pixels lock-free to
the render thread, which copies them into the strip between frames
(RenderPipeline.apply_live_patches, ScrollHelper.patch_columns): at most
four patches or two screens of bytes a frame, no drawing or locks there.
The worker takes over group prefetch once a live element is placed, runs
inside the render gate, and is supervised. Update tick 1s while live
elements exist. Web UI switch for live_refresh. OFFSCREEN_RENDERING.md
describes what was built and why SegmentStrip was not needed.

* feat(sports): live Vegas cards for the scoreboards (shared layer)

One live element per game, drawn only when what the card shows changes, so
a score changes on a card already crossing the panel. The shared part, so
each scoreboard adopts it in a few lines:

- src/common/sports_vegas.py: game_key, game_fingerprint (the whole game
  dict, frozen: no drawn field can be missed), dedupe_games, VegasCardCache,
  StickyOdds (odds a live poll left out stay drawn), finished_games /
  with_finished_games (a game that just went final keeps its card, after its
  league's live games; one a heuristic only judged over keeps its live
  state, so a tied end of regulation never shows FINAL early).
- SportsScrollDisplay.make_vegas_renderer() is the override point;
  build_vegas_elements() and SportsScrollDisplayManager
  .get_vegas_elements_for() do the rest. A card's version includes its
  teams' ranks, which the renderer draws from the rankings cache.
- SportsLiveSharedMixin._record_finished_game() / finished_games_snapshot():
  held for FINISHED_GAME_TTL after it leaves the live list.

A sport that does not implement make_vegas_renderer keeps its ordinary Vegas
content, so no scoreboard changes until it opts in.

scripts/render_plugin.py --vegas renders a plugin's Vegas block as the
ticker lays it out, and --timeline stacks it at successive moments as
the ticker would update it in place; the join is now
render_pipeline.join_plugin_rows().

* feat(vegas): keep live games in the ticker by default

display.vegas_scroll.live_in_ticker now defaults to true: through a live
game the marquee keeps running and the live scoreboard takes extra turns in
it -- its cards updating in place while they scroll -- instead of the ticker
giving way to the full-screen scoreboard.

The new default would reach nobody on its own: every existing config holds
an explicit false copied from the template (there was no control for it),
and the template merge only adds missing keys. ConfigManager therefore turns
a stored false on once, with a backup, and records live_in_ticker_migrated
so a false chosen afterwards stays. The marker is never in the template.

A "Keep live games in the ticker" checkbox under Vegas mode sets it. Tests
that pin the full-screen takeover now say live_in_ticker=false.

* refactor(sports): a default _determine_game_type on SportsScrollDisplay

render_vegas_card looked the method up with getattr and a None default, which
static analysis (Codacy) reports as calling something that may not be
callable. The base class now has the default -- the card type from the game's
state -- and the plugins that define their own override it as before.

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

* fix: review follow-ups on the shared live-card layer

- The reused Vegas renderer always gets the current rankings, empty
  included, so ranks cleared since are not kept drawn.
- render_plugin.py: --timeline refuses --no-live (a timeline shows live
  elements changing), --timeline/--no-live need --vegas, and the Vegas
  paths create the output's directory like the display path does.

ChuckandClaude Opus 5.5 64c7289593 feat(display): systemd watchdog and heartbeat for a frozen render loop (#687)
If the render loop gets stuck inside a plugin's display(), ledmatrix.service
stays active and the panel stays frozen. This adds a way to detect that.

- src/display_watchdog.py (standard library only) sends sd_notify over
  $NOTIFY_SOCKET and writes /run/ledmatrix/display-heartbeat.json. Only the
  render thread counts: beats from other threads are ignored.
- ledmatrix.service: WatchdogSec=120, NotifyAccess=main,
  RuntimeDirectory=ledmatrix (0755), RestartSteps=4 and
  RestartMaxDelaySec=2min. It stays Type=simple. run.py widens the watchdog
  to 15 min for start-up, and load_plugin() does the same on the render
  thread. The loop arms after its first frame.
- /api/v3/health adds checks.display_loop: running, stalled (no heartbeat
  for over 60s, which makes the status degraded) or not_reported. With web
  login on, a caller who is not logged in still gets only healthy/degraded,
  and a stall degrades that answer.
- The update verifier requires a fresh heartbeat from the restarted display
  when the display it replaced was writing one. A frozen panel is rolled
  back.
- Existing installs get the systemd watchdog only after install_service.sh
  is re-run. The heartbeat works right away.

ChuckandClaude Opus 5.5 b09434a418 refactor(plugins): the display publishes plugin runtime state; retire plugin_state.json (#690)
Stage 2 of the web plugin catalog, after #688.

- The display publishes a plugin runtime snapshot (plugin_runtime.py) to
  the shared cache: per plugin loaded, lifecycle state, a short redacted
  error summary, the version it loaded and when, plus published_at /
  stale_after / running. Written on change (throttled to 10 s; the
  RUNNING/ENABLED flip of an ordinary update is not a change) and once a
  minute otherwise; cleanup() publishes running: false.
- The web reads it back and restores loaded / state / error_info in
  /api/v3/plugins/installed (plus loaded_version, loaded_at and
  data.runtime). Only a live snapshot counts; stale, stopped or missing
  answers null and says which.
- data/plugin_state.json is retired: every reader and writer moved to
  config + disk (desired) or the snapshot (observed). Nothing in it was
  non-derivable, so nothing is migrated and an existing file is left
  unread. The web-side PluginStateManager (state_manager.py) is removed;
  the display's plugin_state.PluginStateManager is the only state machine.
- StateReconciliation compares config + disk with the snapshot, reporting
  enabled-but-not-loaded and older-version-loaded as no_action findings.
- Backups list installed manifests with enabled from config.json.

ChuckandClaude Opus 5.5 c0d97e4867 fix(plugins): one hung plugin no longer stops every plugin from updating (#677)
The update worker no longer blocks forever on a plugin whose display()
never returns. It waits at most PLUGIN_LOCK_TIMEOUT (5s) for a plugin's
lock, then skips that plugin's update (a report-only "busy skip" in
health) and keeps updating every other plugin. display() frames are timed
(slow calls logged and counted; calls past the executor timeout recorded as
hangs), a hung update() is recorded, and on_config_change() now runs under
the plugin lock or is deferred to the worker. The plugin-facing API is
unchanged.

ChuckandClaude Opus 5.5 c3a7a110c4 fix(display): on-demand loads a disabled plugin live instead of failing (#678)
* fix(web): on-demand no longer restarts a running display service

POST /display/on-demand/start treated start_service (default true, sent by
"Preview on display", the on-demand dialog and the MQTT bridge) as
"restart": with the service running it ran systemctl stop, slept 1.5s and
started it again. Every request cold-started the display process -- every
plugin reloaded, panel blank -- to deliver a request the running process
already reads from the cache mailbox every ON_DEMAND_POLL_INTERVAL (0.25s),
including mid-dwell, mid-screen and mid-Vegas. The restart bought nothing:
startup only restores a session the display saved itself
(display_on_demand_config), so the new request arrived through the same
mailbox either way.

start_service now means "start it if it is not running". The stop route
coerces stop_service to a boolean so "false" no longer stops the service.
test_api_v3_on_demand_restart.py pinned the old restart path; it now pins
the replacement. Docs updated.

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

* fix(display): on-demand loads a disabled plugin live instead of failing

The display process only loads enabled plugins, so an on-demand request for
a disabled one -- "Preview on display" offers it on every config page, with a
note that the plugin will be enabled for the preview -- failed with
invalid-mode. Nothing enabled it short of a restart, and the on-demand route
no longer restarts the service.

_activate_on_demand now loads an installed-but-not-running plugin through
the live-enable path (load_plugin + _register_loaded_plugin), with a new
load_plugin(force_enabled=True) so the instance runs enabled while
config.json keeps saying disabled. The plugin is tracked in
_on_demand_loaded_plugins, and the main loop unloads it through
_unregister_plugin once on-demand moves off it (stop, expiry, another
request, or a failed request that ends the session) -- right after its own
poll, where no display() is on the stack. A failed load publishes status
error with load-failed. A plugin enabled during the session stays loaded.

A session restored after a restart uses the same tracking instead of
setting enabled in the config dict config_manager caches, so its plugin is
unloaded when the session ends rather than staying loaded until the next
restart. Ending a session no longer resumes the rotation onto a plugin that
is about to be unloaded, which a restored session did.

Also: a stop sent while on-demand is inactive clears a failed request's
error, instead of /display/on-demand/status reporting status: error until
the state aged out.

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 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 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 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 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.

* 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.

* 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 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.

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

* 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:`.

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

* 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.

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

* 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 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.

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

* fix: call forget_manager_fonts through a hasattr check pylint can follow

getattr(..., None) then callable() is fine at runtime, but pylint's E1102
("not callable") can't see through it, and Codacy fails the check on it.

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.

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

* feat(web): show plugin errors in the Logs tab

A compact panel under the log viewer: per-plugin error counts, repeating
errors (type, count, affected plugins, a sample message, last seen) and a
Clear button, with empty states for "no errors" and "display service
hasn't reported yet". Polls every 15 s while the tab is active; all text
goes through escapeHtml.

* fix(errors): redact the published snapshot before clipping it

Keeping only a traceback's tail (or clipping a message) could cut an
`api_key=` marker off while keeping the secret after it, and the web side's
redaction would then have nothing to match. The display now redacts every
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 cd5a4e2251 fix(display): apply on-demand, brightness and schedule changes mid-screen (#618)
* fix(display): apply on-demand, brightness and schedule changes mid-screen

The main loop read the on-demand mailbox, the on/off schedule and the
brightness target once per pass -- once per screen. A dwell can be a minute
and a Vegas iteration runs for max_cycle_duration (240s), so on a Pi an
on-demand request posted at 10:54:27 was activated at 10:57:24, and two
brightness saves 12s apart inside one 30s screen never reached the panel.
During Vegas nothing read the mailbox at all: _check_vegas_interrupt only
checked on_demand_active, which only the main-loop read sets.

_service_pending_changes does the main loop's on-demand poll, expiry,
schedule and brightness steps, throttled to PENDING_CHANGES_INTERVAL (the
existing 0.25s mailbox floor), on the display thread. It runs from the Vegas
interrupt checker, the high-FPS and once-a-second render loops (replacing
their direct on-demand poll) and _sleep_with_plugin_updates; between passes
it costs one monotonic compare. A brightness change re-pushes the current
frame, since the panel only shows it from the next push.

Callers act on what it leaves behind: Vegas yields on an on-demand start or
the display being scheduled off (and the main loop then blanks instead of
rendering a screen), the render loops break on a schedule-off as they
already did on a mode change, and the dwell sleep returns early on an
on-demand start/stop or a schedule flip -- so the 60s scheduled-off sleep
now wakes for an on-demand request. The main loop no longer rotates after
a dwell that ended that way, which advanced a new on-demand session past
the mode that was asked for.

A brightness set_brightness() refuses is not retried until the target
changes, so the 4Hz pass doesn't log the same failure (fallback mode)
four times a second.

* test(display): a screen scheduled off midway stops rendering

Covers the schedule-off break added to the high-FPS and once-a-second

past the boundary.

live health data comes from PluginHealthTracker, which is untouched.

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

* refactor(store): drop the never-set uninstall tombstones

Nothing in production called mark_recently_uninstalled, so the
reconciler's was_recently_uninstalled check was always False. The
persistent uninstall registry is what actually stops resurrection; the
reconciler test now exercises that gate instead.

* refactor(common): delete unused config/display/game helpers, utils and error_handler

Nothing in core, the web UI, scripts or the plugin monorepo imports
config_helper, display_helper, game_helper, utils or error_handler; only
their own tests did. The error_handler re-exports leave src.common's
__all__; APIHelper, TextHelper, ScrollHelper, LogoHelper and the adaptive
layout exports are unchanged.

* refactor(config): drop ConfigService's unused versioning and save API

ConfigVersion, get_version/get_version_history/get_version_config,
rollback, save_config, reload, get_plugin_config and the backward-compat
load_config/get_config_path/get_secrets_path had no callers. The display
controller only uses get_config, subscribe, unsubscribe and shutdown,
plus the file watcher. Change detection now compares against the
current checksum instead of the last history entry.

The subscriber tests asserted `callback.called or True`; they now
reload the way the watcher does and assert the notification.

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

* refactor(plugins): drop unread plugin state history and callbacks

plugin_state.PluginStateManager kept a bounded per-plugin transition
history that only get_state_history (tests only) read; get_state_info
reports a separate lifetime count, which stays. set_error_info and
record_display had no callers, and set_state_with_error's `error`
argument only fed the history.

The web-side state_manager.PluginStateManager loses
subscribe_to_state_changes, _notify_callbacks, set_plugin_error and
get_state_version, none of which had callers; with no subscribers the
old-state copy in update_plugin_state went with them.

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

* refactor(plugins): remove unused PluginManager methods and attribute guards

update_all_plugins was only called by a test (the display loop uses
run_scheduled_updates); get_plugin_health_metrics,
get_plugin_resource_metrics and get_plugin_state had no callers; and
plugin_modules was written but never read. plugin_directories is now
initialised in __init__, so the hasattr() guards around it go.

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

* refactor(plugins): remove unused executor, loader, store and package helpers

- PluginExecutor.execute_safe: no callers.
- PluginLoader._parse_semver: only its own tests; compatibility.parse_semver
  is the live copy and test_compatibility.py already covers it.
- PluginStoreManager.get_installed_plugin_info: no callers.
- PluginResourceMonitor._local: never read.
- src.plugin_system.get_store_manager and __api_version__: no importers in
  core, scripts or the plugin monorepo.

* fix(wifi): stop storing Wi-Fi passwords in wifi_config.json

WiFiManager appended every joined network's SSID and password, in
plaintext, to saved_networks in config/wifi_config.json, and nothing
(web UI, backup restore, scripts) ever read them back: NetworkManager
keeps its own credentials. The writes are gone, and loading the config
now drops any saved_networks key and rewrites the file, so passwords
already on disk are scrubbed.

Also removes _check_dnsmasq_conflict (never called) and _detect_trixie,
whose result only reached one log line, along with the
NM_CONNECTIONS_PATHS constant only it used.

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

* refactor(display): remove unreachable and unused DisplayController code

- _follower_rebuild_scroll_image: never called.
- mode_duration (never read) and last_mode_change (write-only).
- The `chosen_cap <= 0` branch: chosen_cap is either the minimum of
  caps already filtered to > 0 or DEFAULT_DYNAMIC_DURATION_CAP (180).
- The `max_duration < min_duration` branch directly after
  `max_duration = max(min_duration, max_duration)`.
- The circuit-breaker branch's `display_result = False` and
  `manager_to_display = None`: the first is overwritten a few lines
  later, the second is already None there.
- The bool-to-bool conversion of execute_display's result, which is
  always a bool.
- The `loaded_plugins` lookup in _update_modules: PluginManager has no
  such attribute, so it always fell through to `plugins`.

geometry.find_item_boundary and StreamManager._refresh_plugin_content
had no callers at all.

  the fixture plugin); test_plugin_matrix.py already covers every
  discovered plugin. Their PluginTestBase and the fixtures only it used
  (plugins_dir, mock_display_manager, mock_cache_manager,
  mock_plugin_manager, base_plugin_config in test/plugins/conftest.py) go
  with them.
- test_plugin_system.py: test_discover_plugins (body was `pass`) and
  test_dependency_check (a comment), plus the test_plugin_manager fixture
  only the former requested.
- test_display_manager.py: test_draw_image asserted that an image it had
  just assigned was not None.
- test_display_controller.py: the rotation and schedule-override tests
  re-implemented the run-loop arithmetic inline and asserted on their own
  result without calling the controller.

* 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.

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.

* 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.

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

* 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

README.md). MIGRATION_GUIDE presented 'sudo install_service.sh --help'

* 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.

* 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

pair outranks scroll_pixels_per_second, and gives the scoreboards'

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.

* docs(scripts): monorepo workspace layout; fix_perms and install READMEs

MULTI_ROOT_WORKSPACE_SETUP described one sibling repository per plugin;
setup_plugin_repos.py links ../ledmatrix-plugins/plugins/* into
plugin-repos/ and update_plugin_repos.py pulls only the monorepo, and the
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.

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

* 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 869e36fb2f feat(web): weekly automatic updates with health check and rollback (#581)
* feat(web): weekly automatic updates with health check and rollback

A General-tab toggle (off by default) checks for and installs LEDMatrix and
plugin updates once a week, overnight in the configured timezone.

- Pre-update checks skip (and report) instead of forcing: local edits or
  commits, merge/live rebase, no upstream, low disk, missing health check, or
  a version that was already rolled back. An abandoned rebase (HEAD back on a
  branch) is cleared, since it would otherwise block every pull.
- The pull reuses the Update Code path (now perform_core_update(), which
  reports dependency install failures as data).
- ledmatrix-update-verify.service, started via a .path unit from a request
  file, restarts the services from its own cgroup, requires them to come up
  and stay up, and otherwise resets to the previous commit and reinstalls the
  previous requirements. It runs a copy of the checker taken before the pull.
- No SSH needed: switching the toggle on restarts the display service, which
  (as root) installs the two units from the repo templates for the web user.
  first_time_install.sh installs them too and takes --enable-auto-update /
  LEDMATRIX_AUTO_UPDATE (passed through by one-shot-install.sh).
- Plugins update after the code passes its check; failures, blocks and
  rollbacks raise an Overview banner and show under the toggle.

Tested end to end on a Pi: web-UI setup, a good update, a broken web service
and a broken display (both rolled back), a blocked local edit, and an
abandoned rebase found on the device.

* fix(auto-update): CI failures on Linux

- Keep the setup result when chown fails. CI runs as a non-root user, where

- Register the two new /api/v3/system/auto-update routes in the URL map
  snapshot.
- Use utility classes app.css defines (space-y-1, hover:text-red-600).

* fix(auto-update): address review feedback

- Health check: a failed restart command no longer lets the check run
  against the still-running old process; it counts as a failure (and after a
  rollback, as a failed rollback). An unreadable restart count is never
  treated as stable, since a crash loop looks healthy between attempts.
- Installer writes the auto_update setting to a temp file and swaps it in,
  keeping mode and owner, so a running config watcher never reads a
  truncated config.json.
- Verify unit quotes its command-line paths (install folders with spaces);
  setup refuses folder names systemd would reinterpret (%, quotes,
  backslashes, control characters) and says so on the General tab.
- The auto-update status route no longer returns exception text.

* fix(auto-update): keep error detail in the status route's 500

test_web_error_detail requires every 5xx handler to log the traceback and

diagnosable from the web UI. Dropping it for CodeQL broke that policy.

CodeQL (py/stack-trace-exposure, #709) flagged the route's own except,
which returned describe_exception(e). web_interface/app.py's error handler
already logs the traceback and returns the same redacted detail for any
unhandled exception, so the local copy is removed: same response, no new
exception-to-response flow, and test_web_error_detail's policy still holds.

ChuckandClaude Opus 5 577f5501a6 perf(plugins): stop re-deriving a display() signature the caller already cached (#549)
display_controller resolves once, and caches, whether a plugin's display()
takes a display_mode keyword -- self._plugin_accepts_display_mode, populated
right before the dispatch. It then handed the executor a
types.SimpleNamespace wrapping a closure, and execute_display() ran
inspect.signature() on that to work out the same thing.

Because the SimpleNamespace is rebuilt per call, the callable was new every
time, so nothing inside the executor could ever cache it either. Measured at
~39us per dispatch on a Pi 4, for a value the caller had a line earlier.

execute_display() now takes accepts_display_mode, falling back to inspecting
only when a caller does not pass it, so existing callers are unaffected.

Also documents two things that read as bugs and are not:

- execute_with_timeout()'s timeout is advisory. Nothing cancels the thread --
  Python cannot -- so on expiry the operation runs to completion in the
  background and only the caller gives up. A permanently hung plugin leaks a
  daemon thread per attempt. This is why callers holding a lock across the
  call must release it from inside the wrapped callable, as run()'s
  _release_display_lock already does.

- Only the first display() of each mode goes through the executor; the
  per-frame loops call display() directly. That is deliberate: a thread per
  frame would cost more than an advisory timeout buys. Both loops now say so,
  so the asymmetry does not read as an oversight.

ChuckandClaude Opus 5 e23f1f45d3 feat(starlark,on-demand): the third-party fixes worth taking, plus a Home Assistant MQTT bridge (#538)
* feat(starlark,on-demand): the third-party fixes worth taking, plus an MQTT bridge

Analysis of ant456/ledmatrix-fixes-repo, a third-party collection of
patches and services built while running this project on Starlark apps
under MQTT control. Its patches are whole-file copies taken against an
older tree, so applying them as written would revert #523's frame
pacing, #534's display() bool returns and the GitHub token masking in
plugins_manager.js. Three of its claimed fixes are already in main, and
its api_v3 Starlark routes are #535's. What follows is the rest --
verified against current code, and reimplemented where the patch's
approach did not hold up.

**On-demand display.** `pinned` reached the controller from the API, was
stored on it and republished in the status payload, but never narrowed
the rotation -- a pinned request still cycled every mode its plugin
owns. Right for a sports plugin, whose modes are views of one subject;
wrong for a plugin whose modes are unrelated, which is every Starlark
app. Now honoured, and it survives a restart.

Restarting while on-demand was active loaded *only* the on-demand
plugin, so normal rotation had nothing to return to for the life of the
process -- and a restart mid-session is routine, since that is how an
update is applied. The panel came back cycling one plugin's modes with
no way out but clearing the cache by hand. Every enabled plugin loads
now; on-demand still resumes on its saved mode.

Stop requests are exempt from the duplicate guards on purpose, so that a
second click stops a mode a race left running -- which means consuming
the mailbox is the only thing that ends one. It was never consumed, so
the same stop was re-read and re-processed on every poll, forever. Both
paths now share one compare-before-delete helper.

**Starlark rendering.** `extract_schema` parsed the source with a regex,
which can only see option lists written out literally: an app whose
dropdown is filled from a live API call inside `get_schema()` came back
empty, and the config form offered nothing to pick. Now runs `pixlet
schema`, which executes the app, and falls back to the parser when
Pixlet is absent, too old for the subcommand, or the app fails to run.
The third-party patch replaced the parser outright and hardcoded
/usr/local/bin/pixlet; this keeps the fallback and the binary search.

A `|` in a config value was dropped by a shell-metacharacter filter,
though the command is a list with no shell involved -- and apps do use
it as a separator inside one value. The key went missing silently and
the app rendered its own "not configured" screen with nothing to say
why. And a 0-byte render was reported as success: Pixlet exits 0 and
writes nothing when an app has no content, which read downstream as a
working app drawing a black panel.

**Starlark display.** `display()` ignored the mode it was called with,
so a specific app could not be addressed. It now accepts `display_mode`
-- which is the whole mechanism, since the controller inspects the
signature before passing it. Found while there: `_select_next_app` ran
only while `current_app` was unset, so with several apps installed the
first was picked once and shown forever while the rest were rendered on
schedule and never displayed. And `enable_scrolling` was missing, so
multi-frame apps were called once per rotation slot and never advanced
past frame one.

**GET /api/v3/display/modes.** Every mode that can be requested
on-demand, with the plugin that owns it. Nothing exposed this, so
anything driving the display from outside the web UI read each plugin's
manifest.json off disk and reimplemented PluginManager's fallbacks. It
also triggers discovery, which is otherwise lazy and normally happens
because a person opened the dashboard.

**integrations/mqtt_bridge.** Home Assistant control over MQTT
Discovery: a mode select, a stop button, power, brightness. Rewritten
against the API rather than the filesystem, so it needs no read access
to config.json and cannot drift from the web UI. paho-mqtt 2.x
VERSION2, TLS, an availability topic that is also the last will, and
secrets from the environment.

**Two opt-in extras.** A DNS single-request unit, for glibc's parallel
A/AAAA lookup stalling ~5s per name on routers that answer only the A
query -- which makes any plugin calling an external API slow and
Starlark apps, which have a render timeout, fail outright. And a Pixlet
config editor: a script you run and Ctrl+C rather than the third-party
version's always-on unauthenticated Flask service, since it stops the
display for the length of a session. Neither is installed by default.

Long Starlark app names now wrap instead of overflowing their card.

115 new tests across 5 files. Also unblocked
test_starlark_display_contract.py, which was silently skipping wherever
fcntl is absent. Whole suite: no new failures against main.

* fix(mqtt_bridge): the five issues Codacy flagged on this branch

All in the new bridge, all real:

  * requests floor was 2.31.0, which carries CVE-2024-35195,
    CVE-2024-47081 and CVE-2026-25645. Raised to >=2.33.0,<3.0.0, which
    is what the project's own requirements.txt already pins.
  * `import time` was never used.
  * `"mqtt_password": None` in DEFAULTS read as a hardcoded credential.
    It is the "no password configured" default; marked nosec B105, the
    convention used elsewhere in the repo.

Also dropped an unused `build_app` from the display-modes test imports.

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

* fix: the review findings on this PR

Nine of CodeRabbit's ten, plus the CodeQL alert. The tenth is wrong and
is answered below.

**One bad config section blanked the whole mode list.**
`/display/modes` read `full_config.get(plugin_id, {}).get('enabled')`,
so a non-dict under a plugin id -- a shape DisplayController already
guards, so it happens -- raised AttributeError mid-loop and answered 500
with no modes at all. Every MQTT bridge entity is built from that list.
Now skipped with a warning.

**The DNS scripts reported success they had not earned.** Three separate
paths: `resolvconf -u` failing was swallowed by `|| true`; the
systemd-resolved branch exited 0 without applying anything, so the
oneshot unit recorded success while the workaround was inactive; and the
installer's `|| echo` turned a failed start into "installation
complete." with exit 0. All three now fail loudly. `single-request` is a
glibc resolv.conf option with no resolved.conf equivalent, so on those
hosts the honest answer is that it cannot be applied.

A NetworkManager-generated resolv.conf is regenerated on connection
changes, not only at boot, and the unit is oneshot with RemainAfterExit
-- so the option can vanish mid-boot with nothing to put it back. Now
detected and stated plainly rather than implied to be permanent.

**`Before=` does not order a manual restart.** It only orders units
already in the same transaction, so `systemctl restart ledmatrix` could
bypass the fix. install_dns_fix.sh now writes a ledmatrix.service
drop-in with Wants= and After=. Wants=, not Requires=: a DNS workaround
failing should not stop the display.

**The Pixlet editor's `--lan` is gone.** `pixlet serve` has no
authentication, and a printed warning is not access control. Loopback
only, with the SSH port-forward in the header where the flag used to be
documented -- SSH does the authenticating and nothing is left listening.

**The MQTT example config now defaults to TLS** on 8883. The installer
copies it verbatim, and without TLS the broker password and every
command cross the network in cleartext. A plaintext broker is still
supported and documented, and the bridge warns once at startup when a
password is configured without TLS.

**Not taken: "the upstream Pixlet CLI has no `schema` subcommand."**
Upstream tidbyt/pixlet has none, but `scripts/download_pixlet.sh`
installs `tronbyt/pixlet`, whose `cmd/schema.go` is
`schema [PATH]` -> JSON on stdout, built on
`runtime.NewAppletFromPath`, so it does execute `get_schema()`. That is
exactly what extract_schema_via_pixlet calls. A binary without the
subcommand exits non-zero and falls back to the source parser, which is
already covered by a test.

**CodeQL stack-trace exposure: not taken either.** I removed `details`
first and that broke
test_web_error_detail.py::test_no_api_v3_handler_discards_its_exception,
which enforces `describe_exception` across all ~75 handlers -- written
because a device with failing storage answered "see logs for details"
from the log viewer itself. describe_exception redacts credentials; the
trade-off is the project's and is already made. Restored, with the
reasoning in a comment.

11 new tests. Whole suite: no new failures against main, 4127 passed.

ChuckandClaude Opus 5 d12323e7f1 perf(scroll): pace frames to the panel — 44→100 fps, stalls 14% → 0.02% (#523)
* perf(scroll): pace frames to the panel, not to a fixed sleep

Scrolling ran at 44-46 fps on a 2x128x64 chain and 14-17% of frames took
41-53ms, which reads as judder. Four independent causes, each measured on
the hardware; details and the diagnostic recipe are in
docs/SCROLL_PERFORMANCE.md.

The high-FPS loop slept a flat 8ms after every render. display() has
already blocked on the panel's vsync by then, so that sleep was added to a
wait that had happened: ~4ms of render plus 8ms put each iteration at ~12ms
against a 10ms refresh grid, so every swap missed a refresh and the loop
settled at 50fps while asking for 125 -- with no headroom, so a further
14% of frames slipped again. It now sleeps only the remainder, with a 1ms
floor so plugin threads still get the GIL.

ScrollHelper stepped position on a wall clock at 1/scroll_delay steps per
second. Plugins set scroll_delay to the frame period, so that comparison
sat exactly on its own threshold: a frame arriving a hair early moved zero
pixels and rendered an identical frame, dirty-tracking skipped the swap, it
returned in ~2ms, and the beat repeated. No scroll_delay value tunes that
out -- a shorter delay trades stalled frames for periodic double-steps.
Both modes now accumulate elapsed time at the same configured speed, so
position stays proportional to real time.

Sub-pixel blending goes back to off by default. It renders a half-step by
mixing two adjacent columns, which on a coarse panel showing pixel-font
text alternates crisp and smeared frames and reads as shimmer -- visibly
worse than integer stepping on the hardware. Vegas mode still opts in.

disk_cache uses orjson when importable, falling back to the stdlib. Encoding
a ~1MB record drops from 14.8ms to 5.4ms end-to-end, and that work holds the
GIL while a marquee is on screen. display_manager also checksummed the whole
framebuffer twice per frame (dirty tracking, then the preview snapshot); the
snapshot now takes the checksum the caller already computed.

New src/common/scroll_config.py resolves scroll settings in one place. Five
ticker plugins each hand-rolled this and disagreed: odds-ticker ranked the
deprecated scroll_pixels_per_second above the documented scroll_speed/delay
pair, and because that key carries a schema default the documented settings
were dead for every user (ChuckBuilds/ledmatrix-plugins#408), while
ledmatrix-leaderboard read the same key only as a fallback. The resolver also
warns when a speed will not advance a whole number of pixels per refresh,
which is the property that actually determines whether a scroll looks smooth.

scripts/build_rgbmatrix_nogil.sh rebuilds the rgbmatrix binding so it
releases the GIL. Upstream declares SwapOnVSync without nogil, unlike
SetPixel/Clear/Fill beside it, so the render thread held the GIL for the
whole vsync wait and starved background threads into long uninterruptible
bursts. The script patches, builds and self-verifies into a scratch tree;
--install backs up the original and rolls back if the service does not come

* fix(display): keep the panel swap locked to vsync while scrolling

Dirty tracking skipped SwapOnVSync for byte-identical frames. That is the
right call for static content, but SwapOnVSync is also what paces the render
loop, so skipping it skips the wait for the panel: a duplicate frame returns
in ~8ms instead of ~10ms on a 100Hz panel, advances the strip only 0.8px
instead of 1.0px, and so makes the next frame more likely to repeat as well.
The effect sustains itself once it starts.

Measured over 20 minutes on a 2x128x64 chain, both scrollers configured
identically at 100 px/s:

    leaderboard   10ms x35, 11ms x3            (clean)
    odds-ticker   10ms x26, 8ms x7, 15ms x5    (~20% duplicates mid-scroll)

The duplicates were not end-of-cycle idling -- 38% of fast frames fell within
90s of a scroll completion against 35% of normal frames, a null result. The
trigger is per-frame work: odds does more of it, and more variably, so it is
first to land a frame that advances less than a whole pixel.

Pushing an identical frame costs one canvas copy. Falling out of vsync lock
costs smooth motion. Static content is untouched, because
is_currently_scrolling() expires on its own inactivity threshold -- covered
by test_stale_scrolling_state_stops_forcing_pushes so a plugin that stops
scrolling without saying so cannot pin the panel into always-push.

Also de-flakes test_snapshot_still_written_on_skip, which asserted a strict
mtime increase between two writes that can land in the same filesystem tick;
it failed about two runs in three on Windows regardless of the code under
test. The file is now backdated before the check.

156 tests pass on the Pi. Not yet confirmed by eye on the panel.

* fix(scroll): report the frame-time tail, and stop the row-major blit

Two problems, both found by looking at the panel rather than the metric.

The frame-stats line reported ONE instantaneous frame every 5 seconds --
about 1 frame in 500 -- printed beside a 100-frame average. Both hide exactly
the fault they are used to chase: a 2ms duplicate and a 21ms double-wait
average to precisely 10ms, so a ticker stalling on half its frames still
reports a healthy "Avg FPS: 100.0". That reading cost several rounds of
chasing the wrong layer. The line now aggregates every frame since the last
log and reports median, p95, max, min, and explicit stall and skip rates
(past 1.5x the median missed a refresh; under half never reached the panel,
because dirty tracking skipped the swap so the frame never waited on vsync).

On the hardware this now reads:

    leaderboard  100.0 fps over 501 frames | median 10.00ms p95 10.05ms
                 max 10.34ms | stalls 0 (0.0%) skips 0 (0.0%)

The binding rebuild's blit patch becomes opt-in (RGB_PATCH_BLIT=1, default
off). Reordering that loop to row-major changes what a torn frame looks like:
column-major tearing shows as a vertical seam, row-major as a horizontal split
between the panel's upper and lower halves. On a 1/32 scan panel that reads as
a one-pixel fold across the middle of every panel, which is what was reported
on hardware and what went away when the blit was reverted. All of the measured
gain comes from the SwapOnVSync change, so the risky half is simply not worth
taking; the header says so.

Also fixes --install resolving its paths against $HOME, which is /root under
sudo, so it looked in /root/rgbmatrix-nogil-build and died with "no built
module found" on a machine where the build had just succeeded. It now resolves
SUDO_USER's home. Both build paths are verified on the Pi: default yields one
GIL-release site, RGB_PATCH_BLIT=1 yields two.

* feat(scroll): let users pick a crisp speed for their own panel

Whole-pixel motion was previously only available at multiples of the refresh
rate -- 100, 200, 300 px/s on a 100Hz panel. 100 px/s crosses a 256px panel in
2.6s, which is brisk for reading, and everything slower had to blend (blur) or
repeat frames unevenly (judder). There was no way to ask for 50 px/s and get
clean motion.

SwapOnVSync takes a framerate_fraction the display manager never passed. It
holds each frame for N panel refreshes; the panel keeps refreshing at its full
rate throughout, so holding costs nothing in flicker and only changes how often
a NEW image is presented. That turns 50 px/s into one whole pixel every second
refresh instead of half a pixel every refresh.

The crisp speeds are therefore refresh_hz / hold * pixels_per_frame, and that
ladder depends on the panel: a Pi Zero on a long chain has a different set of
good speeds from a Pi 4 on a short one. crisp_ladder() enumerates them and
solve_crisp() picks the best match for a requested speed.

solve_crisp weights motion quality rather than picking the numerically nearest
entry, which matters more than it sounds. Asked for 30 px/s, nearest-by-value
answers 28.6 -- 2px jumps at 14fps -- over 33.3, which is single-pixel motion
at 33fps and obviously better on the panel. The target is also clamped into the
ladder's range first, because relative error saturates near 1.0 for a target
far outside it and the quality penalty would otherwise answer "10000 px/s" with
the slowest entry.

configure() snaps to the ladder and applies the hold when given a display
manager. Without one the hold silently cannot happen and motion falls back to
fractional pixels, so it warns rather than failing quietly. set_frame_hold()
resets to 1 when scrolling stops, so one plugin's pacing cannot leak into
whatever is on screen next.

scripts/scroll_speeds.py is the user-facing part: it prints the ladder for the
configured rate, measures what the panel ACTUALLY manages (--measure, for
hardware that cannot reach its configured limit), highlights the nearest option
to a wanted speed, and demos one live. It never starts or stops the display
service itself -- doing that inside a script stranded the panel twice today.

Speeds below ~20 px/s remain stepped regardless. That is the pixel pitch, not a
software limit.

Also fixes the dirty-tracking test spy, which stubbed SwapOnVSync with a
single-argument function and would have masked the new call as a failed push,
and rewrites a configure() test that had started passing for the wrong reason:
it asserted a judder warning, which snapping now prevents, and was matching the
unrelated "hold could not be applied" warning instead.

183 tests pass on the Pi.

* fix(scroll): tie the frame hold to the scroll, not the plugin

The hold applied in configure() never reached the panel. Plugins share one
display manager, and set_scrolling_state(False) -- fired whenever ANY other
plugin finishes its scroll -- reset the hold to 1. A hold set once at plugin
construction was therefore always gone by the time that plugin rendered.

The symptom was a log line that lied. ledmatrix-stocks reported

    Scroll configured: 50.0 px/s (1px every 2 refreshes = 50.0 fps, smooth)

while the panel measured 100.0 fps, median 10.00ms. Config, resolution and
snapping were all correct; only the pacing silently was not applied.

set_scrolling_state(is_scrolling, frame_hold=1) now carries it, so the hold
lives exactly as long as the scroll that asked for it. configure() reports the
value as ScrollSettings.frame_hold instead of applying it -- applying it behind
the caller's back could never have been right on a shared display manager.
Existing callers are unaffected; the default keeps one frame per refresh.

Verified on hardware: stocks at 50 px/s now measures

    50.0 fps over 251 frames | median 20.00ms p95 20.09ms | stalls 0 skips 0

20.00ms being exactly two refreshes, with the panel still refreshing at 100Hz
underneath so flicker is unchanged.

test_another_plugin_stopping_does_not_strand_a_hold pins the interaction that
broke this.

* fix(scroll,cache): resolve CodeRabbit review on #523

Eight findings, all reproduced before fixing.

scroll_config.configure() read the refresh rate *after* resolve() had
already used it. resolve() fills in target_fps, pixels_per_frame and the
judder warning from that rate, so on a 60Hz panel every one of them
described 100Hz -- and with snap_to_crisp=False nothing downstream
corrected it, so set_target_fps() paced the helper to 100 FPS. The rate
is now settled first, and falls back to the global config rather than
straight to the default.

refresh_hz_from_config() used `(cfg.get("display") or {}).get(...)`,
which raises AttributeError when either level is truthy but not a
mapping -- out of a function whose whole contract is a rate or a default.

The frame-stats line reported the upper-middle sample as the median and
the 96th sorted sample as p95 of 100. Both are also thresholds (stalls
at 1.5x the median, skips at 0.5x), so the counts were biased too. The
arithmetic is now in frame_stats()/format_frame_stats(), testable
without a clock.

configure()'s docstring and docs/SCROLL_PERFORMANCE.md still said it
applies the frame hold and warns when it cannot. It deliberately does
neither since "tie the frame hold to the scroll, not the plugin"; a
caller following the old text would omit set_scrolling_state() and slow
snapped speeds would still present every refresh.

disk_cache had no policy for non-finite floats: orjson writes null,
the stdlib writes NaN/Infinity, and orjson then rejects those legacy
files so DiskCache.get deleted them as corrupt. One behaviour on both
paths now -- write null, keep legacy records readable. allow_nan=False
detects the values; the replacement walk runs only when there is one,
so the ordinary write path is byte-identical and pays nothing.

build_rgbmatrix_nogil.sh picked the build artifact with a glob piped to
`head -1`, which sorts cpython-311 ahead of cpython-313, so a stale .so
staged in from the source tree was installed as core.so while the GIL
check -- which reads the generated core.cpp, not the .so -- still passed.
It now requires the current interpreter's exact ABI name and fails
closed. Its systemctl calls were also unchecked under `set -uo pipefail`:
a failed stop left the old service running, the following start
succeeded as a no-op, and the health check reported SUCCESS for a
binding that was never loaded.

orjson floor raised to 3.11.6 for CVE-2025-67221 (unbounded recursion
in dumps); it covers the project's Python 3.10-3.13 range.

Adds test/test_cache_nonfinite_floats.py (14) plus regression tests in
test_scroll_config.py and test_scroll_helper.py. 9 of the cache tests
and 9 of the scroll_config tests fail against the pre-fix code.

* test(harness): keep the visual double's signature tied to production

Moves set_scrolling_state's frame_hold into the test double here, where
DisplayManager gains it, rather than in #534 where it arrived a PR early.
CodeRabbit flagged the #534 version correctly: a double that accepts an
argument production does not lets the call pass every harness run and
raise TypeError on the panel, which is the one failure a safety harness
exists to prevent.

The drift has now gone both ways across two branches -- double behind
production on this branch, double ahead of it on #534 -- so it is pinned
instead of remembered. test_display_double_parity.py compares the two
signatures and fails with the direction of the drift named. It reads the
files with ast rather than importing them, because display_manager
imports rgbmatrix at module scope and this check should hold on a laptop
and in CI as well as on a Pi.

Plugins begin passing frame_hold in ledmatrix-plugins#462, which is why
production and the double both need it before that lands.

Full suite: 3889 passed.

ChuckandClaude Opus 5 a0d3e64099 fix: ten defects found validating the whole plugin fleet on hardware (#534)
* fix(core): register tom_thumb, accept frame_hold in the test double, wire api_v3's managers

Three independent fixes found while validating every plugin on a 256x64 rig.

FontManager never registered tom_thumb even though assets/fonts/tom-thumb.bdf
ships with the core, so every plugin offering it logged "Font family
'tom_thumb' not found" (16 warnings per countdown render) and had to carry a
private loader to use a bundled font. Closes #524.

VisualTestDisplayManager.set_scrolling_state() lacked the frame_hold parameter
that DisplayManager gained, so any plugin passing it died with TypeError at
render time and failed every size. Nine plugins now make that call;
ledmatrix-stocks and ledmatrix-leaderboard were failing outright and the other
seven only passed because their scroll path was unreachable without data.
Closes #525.

api_v3 declared module-level config_manager/plugin_manager = None that nothing
ever assigned -- app.py sets the blueprint attributes, which the other 150+
call sites use. Three sites read the decoys, so /health reported the config
unreadable and the plugin system uninitialised (making "degraded" permanent and
unreachable-by-design) and /display/current fell back to a hardcoded 128x64 on
every rig. The decoys are removed rather than assigned, so a bare name is now a
NameError at test time instead of a silent None. The same function's first-call
uptime was computed from two separate clock reads and came out negative.
Closes #529.

Verified on the rig: both previously-failing plugins render, the tom_thumb
warnings are gone, /health reports "healthy" with all three checks passing, and
/display/current reports the real 256x64.

* fix(core): unique snapshot temp name, honour on-demand requests, skip empty starlark

The preview snapshot wrote through a fixed "<snapshot>.tmp". /tmp is
world-writable and sticky, and the display service runs as a different user
from the tooling, so a leftover temp owned by anyone else became unopenable
even by root -- fs.protected_regular refuses O_CREAT on a foreign file in a
sticky directory. The preview and the health check's liveness proxy then froze
until someone deleted the file by hand; on the test rig that meant 23 hours of
a healthy display reporting "hardware: stale". Now uses tempfile.mkstemp with
cleanup on failure, matching the hardware-status write a few hundred lines
above. Closes #528.

_poll_on_demand_requests read its mailbox with max_age=3600, and get() defaults
the in-memory TTL to max_age -- so the first request was pinned in memory for an
hour and every later poll returned that stale copy. No second on-demand request
was honoured until the service restarted, while the API kept returning 200.
get() already documents memory_ttl=0 for exactly this cross-process case.
The consumed request is also now deleted: leaving it on disk meant a restart
replayed the previous request, activated it, and ignored the one the caller had
just made. Closes #530.

starlark-apps returned None from display() when it has no app to show, which is
the state of every install without Pixlet and of a fresh one before any app is
added. The controller only skips on a boolean False, so that held a black panel
for the full display_duration instead of rotating on. Closes #456 (core side).

Verified on the rig: two consecutive on-demand requests with no restart between
them are both activated, where the second was previously dropped in silence.

* perf(harness): share one cache across a plugin's renders

_instantiate built a fresh MockCacheManager for every (size, mode), and that
mock is a per-instance in-memory dict, so each render was a cold start. A plugin
that fetches per game or per player re-fetched everything N times over --
baseball-scoreboard at one size took 840s for nine renders where the arithmetic
said ~72s, and at eight sizes it exceeded a 900s timeout.

The second and later renders also never exercised the cache-hit path, which is
what a running rig executes almost all of the time, so a caching regression
could not be caught here.

The cache is now built once per render_plugin_matrix call and threaded down.
The display manager stays per-render -- the bounds checking depends on that --
so only fetched data is shared.

Measured on the rig, same render counts and same goldens:
  tide-display         2s -> 1s   (32 renders)
  cricket-scoreboard  10s -> 3s   (24 renders)
No pass/fail change across tide-display, cricket-scoreboard, clock-simple,
geochron, christmas-countdown, of-the-day, web-ui-info and incoming-packages.

Closes #533.

* fix(scripts): run standalone plugin tests instead of collecting nothing

run_plugin_tests.py discovered every plugin test file and handed the lot to
pytest. Most plugin tests are standalone scripts -- module-level main() plus an
`if __name__ == "__main__"` guard, signalling through an exit code -- and pytest
collects zero items from those. The run printed how many files it had *found*,
then "no tests ran", and exited without executing any of them. On a rig with all
44 first-party plugins that is 151 of 248 files.

Files are now classified and each kind runs under the right runner: pytest for
real test modules, subprocess for scripts, honouring the 0 pass / 2 skip / 1
fail convention ledmatrix-plugins' own runner established (a script that wants a
tty or an LED matrix is a skip, not a regression).

Before:
    $ python3 scripts/run_plugin_tests.py -p countdown -d ~/LEDMatrix/plugin-repos
    Found 1 test file(s)
    collected 0 items
    no tests ran in 0.31s                      rc=0

After:
    Found 1 test file(s) -- 0 collectable, 1 standalone script(s)
    1 passed, 0 skipped, 0 failed (scripts)    rc=0

Verified across three shapes: countdown (1 script), jellyfin-now-playing and
pomodoro-timer (pytest only, 16 and 42 tests), and ledmatrix-flights (11 files
split 4 collectable / 7 scripts, all seven of which had never run).

Closes #532.

Running the flights scripts for the first time also surfaced four genuinely
failing tests there, hidden by the mirror-image bug in the plugins repo's own
runner -- filed as ChuckBuilds/ledmatrix-plugins#464 and #465.

* fix(harness): give an empty-looking mode a few frames before warning about it

check_plugin's "drew nothing but display() returned X" warning fired on a single
frame, rendered with force_clear=True, under a frozen clock. All three defeat a
scrolling plugin, whose first frame is legitimately its blank scroll-in buffer.
Across 44 first-party plugins, 60 of 76 warnings were false -- the rate at which
people stop reading a warning, which matters because the true positives are
real: a mode that draws nothing and does not return False holds a blank panel
for its whole display duration.

An apparently-empty frame is now re-driven for up to 48 more frames with
force_clear=False (force_clear means "reset the scroll", so repeating it would
redraw frame 1 for ever) and with the clock advancing -- freezegun's factory
where time is frozen, a real sleep where it is not, since scroll position is
usually a function of elapsed time. The first frame that draws content replaces
the result.

The clock is moved back afterwards. It is shared by every render in the matrix,
so time borrowed by the probe leaked into later modes and drifted their goldens
-- f1_upcoming picked up 5 spurious drifts before this was restored.

Measured on the rig:

                        empty warns          check
                        before  after
  f1-scoreboard            42      0    48 PASS / 0 FAIL, goldens intact
  ledmatrix-elections      16      0    16 PASS / 0 FAIL
  on-air                    8      8    true positive, kept
  nfl-draft                 8      8    true positive, kept
  clock-simple/geochron/    0      0    unchanged
  christmas-countdown

58 false positives gone, both true positives kept, no golden regressions. Cost
is confined to modes that really are blank: plugins that draw immediately are
unchanged (clock-simple and tide-display still 2s), while on-air -- eight
deliberately blank modes -- goes to 21s.

Closes #527.

* fix(harness): load nested schema defaults, and merge caller config at leaf level

load_config_defaults read only top-level properties. An object property carries
its defaults on its children, not on itself, so everything nested was dropped --
2,386 defaults across 37 of 44 plugins, soccer-scoreboard alone losing 539 of
565. render_plugin_matrix's comment says the plugin then "behaves like a real
install", which for most of the fleet it did not.

_defaults_from_properties now recurses. merge_config deep-merges the caller's
config onto the result so an override lands at the leaf: a shallow merge would
let -c '{"nhl": {"enabled": true}}' replace the whole nhl subtree and discard
every other nhl default, which is the same class of bug being fixed here.

Measured before/after across all 49 installed plugins on the rig: **no render
changed** -- identical PASS/FAIL counts, byte-identical output, goldens intact.
Plugins already fall back to the same values internally via config.get(key,
default), so supplying them explicitly agrees with what they were doing. The
defaults really are arriving now:

  ufc-scoreboard        9 -> 87 defaults
  ledmatrix-flights    51 -> 95
  masters-tournament   10 -> 51
  cricket-scoreboard   22 -> 50
  tide-display         12 -> 18

and hockey-scoreboard, which used to load nhl.enabled=None, now gets
nhl.enabled=True with its full display_modes block.

Caveat worth carrying: the eight plugins with the most nested config
(soccer, baseball, basketball, hockey, lacrosse, football, afl, nrl -- 1,634 of
the 2,386 dropped defaults, 68%) could not be measured. They import
src.common.sports_shared, which the test rig's core branch predates, so they
fail to load there identically before and after. Re-run this comparison against
a core that has that module before trusting the "nothing changed" result for
them; those are exactly the plugins whose renders should change most.

Closes #531.

* refactor: narrow the exception handlers this branch introduced

Codacy flagged the new code; it passes on other recent PRs, so the finding is
mine. Four of the five broad `except Exception` clauses I added were catching
far more than they needed to, which is the same shape as several bugs this
branch fixes -- hello-world's TypeError sat invisible for exactly this reason.

  freezer() / move_to() / tick()   -> (AttributeError, TypeError, ValueError)
  cache_manager.delete()           -> (OSError, AttributeError, KeyError)

The fifth stays broad and now says why: it wraps a call into a plugin's own
display(), which can raise anything, and the first frame has already rendered --
so a failure there must not turn a good result into an error.

Verified against a checkout of main: f1-scoreboard 48 PASS / 0 FAIL with 0 empty
warnings, on-air keeps its 8 true positives, clock-simple 8 PASS. geochron shows
7 golden drifts both before and after this branch, so it is not from these
changes -- its committed goldens predate #521's 1-bit text rendering.

* fix: resolve CodeRabbit review and Codacy findings on #534

CodeRabbit raised six; all six were real.

The test double had drifted ahead of production. VisualTestDisplayManager
accepted set_scrolling_state(frame_hold=...) while DisplayManager did not,
so such a call passed every harness run and would raise TypeError on the
panel -- the one failure a safety harness exists to prevent. frame_hold
belongs to the change that adds it to DisplayManager (#523), so it moves
there and the double matches main again.

The harness swallowed exceptions from re-rendered frames. _settle_loop
re-renders a mode that came back blank, to give a scroll time to draw;
returning silently on a crash meant a mode that renders one good frame
and then explodes was reported as passing. Recorded on result.error now,
keeping the captured frame so the failure stays inspectable.

starlark-apps display() returned True after _display_frame() failed, so
the controller held a dead frame for the whole display_duration instead
of rotating on. _display_frame now returns bool on all three paths.

run_plugin_tests.py used env.setdefault for PYTHONPATH and
LEDMATRIX_CORE, so an inherited value won and the subprocess imported a
different core than the one under test -- ledmatrix-plugins#467 exactly.
Prepends PROJECT_ROOT and sets LEDMATRIX_CORE unconditionally.

The on-demand mailbox is polled after every frame, ~125x/second on a
scrolling mode, and the read is deliberately uncached, so it was that
many disk reads per second to find nothing. Floored at 250ms, which is
imperceptible for a web-UI click. Consuming it also deleted whatever was
present rather than what had just been processed, so a request posted
while the previous one was in flight was thrown away and never ran; the
delete is now keyed by request_id. That narrows the window rather than
closing it -- a true atomic claim needs a primitive the cache layer does
not offer, and the code says so rather than implying otherwise.

Codacy's 2 criticals were bandit B404/B603 on the subprocess call added
to run_plugin_tests.py. Fixed interpreter, argument list, no shell;
annotated with the repo's existing nosec convention. Bandit is clean on
the file.

Adds test/test_on_demand_mailbox.py (8), test_starlark_display_contract.py
(4) and two settle cases in test_harness_empty_claimed.py. 4, 4 and 2 of
those fail against the pre-fix code. Full suite: 3961 passed.

* chore: satisfy Codacy's subprocess checks on the new test runner

Codacy runs Bandit and Opengrep (its Semgrep fork). The new
subprocess.run in scripts/run_plugin_tests.py trips three patterns, on
two different lines:

  Bandit   B404 on the import, B603 on the call
  Opengrep dangerous-subprocess-use-audit          on the run( line
           dangerous-subprocess-use-tainted-env-args on the argv line

A nosemgrep applies only to its own line, so the call line and the argv
line each need one; a single comment on the call covered neither rule
fully. Suppression is the right answer here rather than a rewrite: the
interpreter is sys.executable, the arguments are a list, and no shell is
involved, so there is nothing to word-split or expand.

Matches the pair the rest of the repo already uses for this shape --
permission_utils.py, plugin_loader.py, install_dependencies_apt.py.

Codacy: 0 new issues, up to standards.

* chore: leave visual_display_manager untouched so #523 can merge

The only change this branch made to that file was a docstring, and it
collided with #523's rewrite of the same method -- so #534 and #523 each
merged cleanly against main but conflicted with each other. Reverted to
main's text; #523 owns this method and adds frame_hold to it.

The note the docstring carried ('frame_hold arrives in #523') would have
been stale the moment #523 landed anyway. The parity test in #523 is
what actually keeps the two signatures honest.

* chore: add the Ruff suppression nosec/nosemgrep do not cover

Ruff reports S603 on the same call Bandit and Opengrep do, and none of
the three suppressions covers the others. Confirmed the precondition
first: path comes from discover_plugin_tests(), which globs test files
inside the repo, and the call is a fixed interpreter with a list argv
and no shell.

ChuckandClaude Opus 5 c321b94085 fix(display): retry a plugin that is enabled but failed to load (#495)
* fix(display): retry a plugin that is enabled but failed to load

A plugin whose validate_config() returns False is treated as a hard load
failure. The API then reports enabled=true, loaded=false, error=null: the
plugin is simply absent, with nothing saying why. hockey-scoreboard sat in
that state on a live rig for four days.

The recovery path existed but could not be reached. _reconcile_enabled_plugins
computes to_add = desired - current, and a plugin that failed to load is never
in current, so it stays in to_add and would be retried. But the reconcile is
queued by _enabled_set_changed(), which compares only top-level `enabled`
flags -- and the edit that actually fixes such a plugin (enabling a league,
filling in an API key) is nested inside the plugin's own config section. No
top-level flag changes, so no reconcile is queued, and the save that should
have fixed it does nothing. Only toggling some unrelated plugin -- which does
change a top-level flag -- queues the global reconcile that recovers it.

Add a second gate: queue a reconcile when a discovered plugin is enabled in
config but absent from the running set.

It is deliberately narrow rather than "reconcile on any config change".
Reconcile calls discover_plugins(), a ~39-manifest filesystem scan, and it
runs on the render thread; doing that on every config save would trade this
bug for a frame hitch. Gating on plugin_manifests also keeps non-plugin
sections that carry their own `enabled` flag (schedule, display) from
queueing a reconcile they can never satisfy. In the steady state -- every
enabled plugin loaded -- the new check is False and costs nothing.

The same valid-but-unconfigured => hard-fail shape still exists in
text-display, youtube-stats, birdnet-go, ledmatrix-flights and
mqtt-notifications; this makes all of them recoverable without a restart.

* fix(display): snapshot the plugin mappings under their locks

Addresses the review finding on the cross-thread reads.

_enabled_plugin_not_running runs on the config-watcher thread and read two
mappings the render thread mutates. Catching RuntimeError was not a fix: it
turned a torn read into a coin flip between an unnecessary discovery scan and
a missed retry, which is the bug this PR exists to remove.

Both reads are now snapshots taken under the lock that guards their writes:

- plugin_manifests via a new PluginManager.discovered_plugin_ids(), which
  copies the ids while holding the existing _discovery_lock. Discovery
  rebuilds that mapping entry by entry, so an unsynchronised reader can see
  it half-populated.
- plugin_display_modes under a new controller lock, taken at the only two
  sites that mutate it (_register_loaded_plugin / _unregister_plugin).

The locks are never nested -- each snapshot is taken and released before the
next -- so this cannot deadlock against discovery, which holds _discovery_lock
while it rebuilds.

No cost on the per-frame path. Both mutation sites run during reconcile, which
is rare, and every hot-path read of plugin_display_modes is on the render
thread itself, same thread as the writes, so those stay lock-free.

Tests: the accessor returns a snapshot rather than a live view, and actually
takes the discovery lock (proved from a second thread, since an RLock is
reentrant on the owning one) so a later refactor cannot quietly drop it.

* fix(display): consume the reconcile request before serving it

Addresses the second review finding: a lost update on
_pending_plugin_reconcile.

The flag was cleared after a successful reconcile. Reconcile has already read
its config by that point, so a config change arriving mid-flight set a flag
that the trailing clear then erased -- a request that was never served, and
the newest config never reconciled. That is the same "my save did nothing"
symptom this PR exists to remove, so leaving it would have undercut the fix.

Consume the request before running it instead, and re-arm only on a retryable
failure. A change that lands during reconcile now stays set and is picked up
on the next pass.

The per-frame read stays lock-free. It is a fast path that can only produce a
false negative -- the watcher setting the flag just after it is read is seen
on the next iteration -- never a false positive that loses a request. The lock
is taken only when a reconcile is actually pending or a config change arrives.

Extracted _service_pending_reconcile() so the sequence is testable rather than
buried in run()'s loop; the review asked for a regression test that invokes
the subscriber during reconciliation, which is not reachable otherwise.

Tests: 4 new, covering a request racing in mid-reconcile, the quiet success,
the retryable-failure re-arm, and not reconciling when nothing is pending.
Two of them fail against the previous clear-after-success semantics.

ChuckandClaude Opus 5 08265c1135 feat(vegas): let live content keep its place in the ticker (#457)
* feat(vegas): let live content keep its place in the ticker

Live content used to preempt Vegas outright: while any plugin reported
live priority the display controller refused to run the ticker at all and
showed a full-screen scoreboard instead. Keeping the marquee meant not
seeing live scores; seeing live scores meant losing the marquee.

Two changes, both off by default.

vegas_scroll.live_in_ticker keeps the ticker running through a live game.
Three places assumed the takeover and all three now honour it: the
controller's gate, the coordinator's per-frame pause, and the rotation
switch that would otherwise move current_mode_index underneath a ticker
that never yields.

And the rotation is no longer a strict round robin. It was one slot per
plugin per cycle, so with a dozen plugins enabled a live score came round
once a lap and could be minutes old on screen. A plugin can now hold
several slots, placed by Smooth Weighted Round-Robin -- the same
scheduler the sports plugins already use to rotate their own games. The
property that matters is that repeats are spread through the cycle
rather than clumped: three in a row and then silence would be worse than
no boost at all.

Weight comes from the plugin first, via a new optional
get_vegas_priority_weight(), then from the core: live content earns
live_weight, everything else 1. So existing plugins gain the behaviour
without changes, and the hook exists for the one thing the core cannot
work out -- the core can see that a game is live but not whose, so only
the plugin can say a favorite is playing.

Documented in ADVANCED_FEATURES (worked example, why weights are per
plugin not per game, and that frequency is not freshness),
CONFIG_REFERENCE, PLUGIN_API_REFERENCE, and the config template.

Claude-Session: https://claude.ai/code/session_01Udr6MfaFLUPhX5Fgo67Jf5

* fix(vegas): carry the new keys through config, and correct two docs

Three findings from CodeRabbit, all valid.

to_dict() and update() enumerate keys explicitly and had not learned the
three new ones, so get_status() never reported them and a live config
change never applied -- turning live_in_ticker on in the web UI would
have done nothing until a restart. update() clamps the weights exactly
as from_config does.

The vegas_scroll key count in ADVANCED_FEATURES said 29; the template
has 30. My arithmetic, not the reviewer's.

The third was a documentation error rather than a code one, and I have
fixed it the other way round. The docs claimed a raising
get_vegas_priority_weight() is treated as weight 1. The code instead
falls through to the core's own live-content check, and that is the
better behaviour: the hook is only how a plugin asks for *more* than
live_weight, and has_live_priority/has_live_content are separate methods
guarded separately, so a plugin with a broken weight calculation should
lose the favorite distinction and keep the live boost. Said so in the
code, the base-plugin docstring and the API reference.

The test fake now fails in each place independently, because the two
failures mean different things: a broken hook still earns live_weight, a
plugin that cannot say whether it is live has nothing to fall back on
and weighs 1.

* fix(vegas): stop the heaviest plugin doubling across the cycle seam

Smooth Weighted Round-Robin spaces repeats well within a pass, but it
schedules the heaviest item first and usually last as well. The strip
loops, so those two are neighbours: the marquee showed the same plugin
twice running at exactly the one join a within-cycle check cannot see.
Observed on a live rig at 28 slots -- gaps of 6, 7, 7, 7 and then 1.

Rotating the list does not fix it. Rotation preserves the cyclic order
exactly, so it moves where the seam is drawn rather than the adjacency
itself; the trailing entry has to be swapped with one from the middle.

The first version swapped with the first slot that merely fitted, which
undid the spacing this exists to protect -- it moved a repeat from a gap
of 7 into a gap of 2, more clumped than the seam had ever been. It now
picks the candidate furthest from any other appearance, so the repeat
lands in the widest gap.

Left alone when no candidate exists. A plugin holding most of the slots
has to neighbour itself, and scheduling it is better than refusing to.

Claude-Session: https://claude.ai/code/session_01Udr6MfaFLUPhX5Fgo67Jf5

* fix(vegas): stop the seam repair creating the duplicate it removes

Swapping the trailing repeat with a middle slot moves two elements, and
the candidate filter only guarded one of them. It checked the neighbours
`repeated` would acquire at j, but not what the displaced element would
sit beside at the end -- so ['a','b','c','d','x','y','x','a'] came back
as [...,'x','x'], the seam duplicate traded for a fresh one. Reported by
CodeRabbit with that exact case.

Adding the missing condition fixed it and immediately broke something
else: schedule[j] is schedule[-2] when j is the second-to-last slot, so
that candidate was always excluded, and ['a','b','c','a'] lost the only
repair it has. The same class of mistake twice, from reasoning about
which neighbours two moved elements end up with.

So it no longer reasons. It performs each candidate swap, counts the
cyclic duplicates in the result, and keeps the best one that has none --
preferring whichever leaves the boosted plugin most evenly spread. When
no such swap exists the schedule is returned untouched, which is the
unavoidable case: a plugin holding most of the slots has to neighbour
itself.

Fuzzed across 6,956 seam schedules: none made worse, none lost an entry.

ChuckandClaude Opus 5 9cf30bbbef fix(startup): bound the initial plugin update so the panel lights sooner (#456)
* fix(startup): bound the initial plugin update so the panel lights sooner

DisplayController.__init__ calls _update_modules() once to populate
plugin data before the first frame. It walks every loaded plugin in
turn, and each update blocks the calling thread for up to the executor's
30s timeout, so the uncapped total is the sum of every slow plugin on
the system. The rig's own log:

    Initial plugin update completed in 82.255 seconds
    Initial plugin update completed in 55.123 seconds
    Initial plugin update completed in 25.975 seconds

The panel shows nothing for all of it.

Nothing is lost by stopping early. A plugin that has never updated is
immediately due, so run_scheduled_updates() collects it seconds later --
with the display already running rather than blank.

A deadline alone was not enough: it is checked before each plugin, so
the last one to start could still block for the full 30s, and a 20s
budget produced a 31.8s pass on the rig. The remaining budget is now
passed down as that update's timeout too, with a floor so a plugin
starting on the last sliver is not handed ~0s and recorded as having
timed out for a slot it never had. Measured after: 20.006s.

Found while profiling a scroll freeze with py-spy, which caught the main
thread 9.34s inside execute_with_timeout's join. Worth being clear that
this is startup latency, not the recurring stutter -- _update_modules
has exactly one caller and runtime updates already run off the display
thread.

* feat(display): show the device address on the startup screen

That screen is what the panel holds for the whole initial plugin update,
and on a headless Pi it is the only place the address appears without
going looking for it -- so it now carries the address under
"Initializing".

The lookup connects a UDP socket, which sends no packets: it only asks
the kernel which source address it would route from. That costs 0.03ms
and works with the network down so long as a route exists. Deliberately
not `hostname -I` plus a systemctl probe for AP mode, which is how the
web launcher does it -- two subprocesses with multi-second timeouts, on
the startup path this branch exists to shorten.

Two things had to change for the address to be worth putting there.

The text is now sized to fit rather than fixed at 8px: "Initializing" is
96px in PressStart2P, drawn at x=10, so it already ran off the side of a
64px panel before an address was added. It falls back to 4x6 where that
does not fit, and both lines are centred.

And the test pattern is punched out from behind the block, with the text
drawn white rather than blue. The diagonal runs through the middle of
the panel, which is exactly where this sits, and blue on black reads
fine on a monitor but is marginal on a dim panel. An address that cannot
be read off the wall is not worth showing.

The rendering tests assert against pixels -- no green left behind the
text at any supported size, enough lit pixels to be visible -- rather
than against the geometry that produced them.

* fix(display): keep the startup text blue -- it is a channel reference

The test pattern lights one pure channel per element: red border, green
diagonal, blue text. That is how a glance at the panel tells you whether
led_rgb_sequence is right -- wire it BGR and the border comes up blue
and the text red. Drawing the text white, as the previous commit did for
contrast, lights all three channels and destroys the only blue reference
on the screen.

Reverted to blue, with the reason written down so it is not treated as a
style preference again, and with tests that pin it: the text must be
pure blue, nothing on the screen may be white, and all three primaries
must be present.

The punched-out backdrop stays. It only removes the diagonal from behind
the glyphs, which costs nothing diagnostically -- the diagonal is still
plainly visible across the rest of the panel -- and it is what makes the
address readable at all.

* fix(startup): defer a plugin with too little budget, rather than clamp it

The per-plugin timeout was clamped up to a floor, so a plugin that began
with a sliver of budget left was granted the full floor and ran on past
the deadline: a 20s budget could take 22. The floor existed to stop a
plugin being handed a slot too short to use and then recorded as having
timed out, which is a real concern, but clamping solved it by breaking
the bound.

Deferring solves both. Below the floor the plugin is left to the update
tick, which was already the fate of everything after the deadline, so
nothing new is lost -- a plugin that has never updated is immediately
due. Above it, the timeout is the exact remainder, and the pass cannot
outlast its deadline.

Measured on the rig after the change: 20.002s, 5 plugins deferred.

Also names an unused binding in the initializing-screen test.

Both reported by CodeRabbit.

ChuckandClaude Opus 5 7171e6c022 fix(cache): one cleanup thread per cache directory, not per manager (#453)
The display process ran three cleanup threads over one directory:

    14:22:59.954  display_controller        (the real manager)
    14:22:59.973  startup validation, run 1 (discarded)
    14:23:01.055  startup validation, run 2 (discarded)

Two of those managers existed only to read a directory path.
StartupValidator._validate_cache_directory built a whole CacheManager to
call get_cache_dir(), and validation runs twice -- once before the
plugin manager exists and again after. Each construction also probes
writability by writing and deleting .writetest on the card.

The discarded ones never went away. cleanup_loop closes over `self`, so
the thread keeps its manager alive: two objects that could never be
collected, waking every 24 hours to re-scan the same 9,000-file
directory. Nothing stopped them either -- stop_cleanup_thread had no
callers anywhere in the tree.

Two changes. The validator now takes the CacheManager the application
actually uses, which is also the more correct thing to validate; when
no caller supplies one it still builds its own, but stops the thread
afterwards. And CacheManager now tracks which directory it is sweeping,
so the second manager over a directory skips starting a thread at all.
That is the right granularity regardless of call sites: the sweep lists
a directory and deletes from it, so a second thread only duplicates the
scan. Ownership is released on stop, so a survivor can take over rather
than leaving the directory permanently unclaimed by a dead owner.

Measured directly, three managers over one directory: 3 threads before,
1 after.

ChuckandClaude 6a9d8014e5 Tag plugin logs structurally and surface the active plugin in System Logs (#418)
- get_logger() now returns a PluginLoggerAdapter when given a plugin_id,
  so every plugin log call is stamped with plugin_id automatically instead
  of only calls that explicitly passed extra={'plugin_id': ...}. This makes
  the "[Plugin: x]" prefix reliable in the journalctl-backed log stream.
- display_controller publishes the currently active mode/plugin to the
  shared cache whenever it changes, exposed via a new
  GET /api/v3/display/current-status endpoint.
- System Logs page: adds a "Now showing" banner backed by that endpoint, a
  plugin filter dropdown (populated from parsed log lines), a plugin badge
  per log entry, and fixes log parsing to handle the short-iso timestamp
  format journalctl actually returns (the old regex only matched syslog
  timestamps, so level/plugin extraction silently never ran).

ChuckandClaude Sonnet 5 c90129285c Web UI: mobile navigation, guided onboarding, basic/advanced config tiering + performance (#417)
* chore(web): remove dead legacy client-side plugin-config generator (~2,300 lines)

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Owner-requested layout refinement of the Display Settings tab:

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

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

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

Two gaps reported from live testing on the devpi rig:

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

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

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

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

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

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

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

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

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

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

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

* feat(web): restart-pending banner, unsaved-changes guard, installable web app

Three usability improvements from live testing feedback:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Verified each finding against current code. Fixed:

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

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

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

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

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

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

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

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

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

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

Verified each finding against current code.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

CodeRabbit review on #406, verified against current code:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Chuck 6052a60d22 fix(vegas): restore live plugin-update refresh dropped by sync refactor (#395)
Investigating a user report that Vegas scroll mode doesn't update scores
or game status. Root cause: PR #299 (Mar 28) added a mechanism so a live
score change reached the ticker within a few seconds instead of waiting
for a full scroll cycle -- _tick_plugin_updates_for_vegas() diffed
plugin_last_update timestamps to detect which plugins got fresh data and
called coordinator.mark_plugin_updated() for each, and should_recompose()
checked has_pending_updates_for_visible_segments() to trigger an immediate
hot-swap.

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

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

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

ChuckandClaude Opus 4.8 3b93024993 feat: activate dormant plugin health/metrics subsystem and surface it in the web UI (#388)
* feat(plugin-system): activate dormant plugin health & metrics subsystem

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

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

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

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

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

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

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

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

Addresses CodeRabbit review on #388:

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

Tests: new force_reload staleness cases in test_plugin_health and
test_resource_monitor.

7a6bad29fe feat(display-controller): hot-reload plugin enable/disable without a restart (#374)
* feat(display-controller): hot-reload plugin enable/disable without a restart

Enabling or disabling a plugin in config previously required restarting the
display service: the plugin list and available_modes were built once at init
and the run loop never revisited them. (Per-plugin config *values* already
hot-reloaded; only the enabled set was restart-only.)

Now the controller reconciles its running plugins against the config's enabled
set whenever that set changes:

- The ConfigService watcher thread only sets a `_pending_plugin_reconcile`
  flag (via a cheap enabled-set diff). It never mutates loop state.
- The run loop applies the reconcile on its own thread (top of each
  iteration, deferred while on-demand is active), so loading/unloading and
  rebuilding available_modes can't race with rendering.
- `_reconcile_enabled_plugins` diffs desired vs running plugins, unloads the
  removed ones (cleanup + on_disable + config-unsubscribe via the new
  `_unregister_plugin`) and loads the added ones, then clamps the rotation
  index so the current mode stays valid.

The per-plugin registration done at startup is extracted into
`_register_loaded_plugin` and reused by the live-enable path so both build
identical state. Extracting it also fixes a latent late-binding bug: the
per-plugin config-change callbacks were closures over the loop variable, so
every plugin's callback targeted the last-loaded instance; each now binds its
own id/instance.

Adds test/test_display_controller_plugin_toggle.py covering live enable,
live disable, index clamping, no-op when unchanged, and the enabled-set diff.

* fix(display-controller): don't exit on empty available_modes, guard rotation modulo

Hot-reload means available_modes can legitimately be empty at startup (no
plugins enabled yet) and become non-empty later via the web UI, or vice
versa mid-run. Fix four issues found reviewing this PR:

- run() exited the process entirely when available_modes was empty at
  startup instead of idling, permanently defeating the point of live
  enable/disable for anyone who starts with zero plugins enabled.
- The mode-rotation step divided by len(available_modes) unconditionally,
  raising ZeroDivisionError if the last enabled plugin is disabled between
  frames.
- _reconcile_enabled_plugins() called .get('enabled', False) on a config
  section without checking it was a dict first, raising AttributeError on
  a malformed config value.
- Minor: pop the config-change callback only after attempting to
  unsubscribe it, and log the exception in the config-read fallback
  instead of swallowing it silently.

* fix(display-controller): address review findings on the hot-reload PR

- Idle-wait tick was a fixed 30s sleep, delaying pickup of a plugin
  enabled via the web UI while no modes were active. Shortened to ~1s so
  it's roughly as responsive as the per-frame check once modes exist.
- _unregister_plugin popped the config-change callback from
  _plugin_config_callbacks even when config_service.unsubscribe() raised,
  losing the only reference to it. Now only pops on a successful
  unsubscribe.
- _pending_plugin_reconcile was cleared before _reconcile_enabled_plugins()
  ran, so a retryable failure (e.g. plugin discovery erroring) silently
  dropped the enable/disable request. _reconcile_enabled_plugins() now
  returns True/False and the caller only clears the flag on True.
- Added a warning log for the malformed-config case (a plugin's config
  section present but not a dict) so it's actually visible, and updated
  the existing test to assert it via caplog.

Left the broad `except Exception` around config_service.unsubscribe() as
Exception -- the current implementation is a simple lock+dict/list op that
doesn't document or realistically raise a narrower type, so this is a
defensive catch-all, not user error handling.
