ci: mypy ratchet -- keep type-clean modules clean (71 modules, 536 -> 442 errors) (#661)
* ci: mypy ratchet -- keep type-clean modules clean mypy-clean.txt lists the 71 modules under src/ that type-check clean; scripts/check_types.py runs mypy (--follow-imports=silent) on exactly those files and fails on any error or a missing/unsorted/duplicate entry. A new "Type check (mypy ratchet)" CI job runs it with mypy 1.20.2 and pinned stubs; the manual pre-commit mypy hook now runs the same script (a local hook, so mypy sees the installed requirements like CI does). 35 modules were made clean with annotation-only fixes: hints, typing.cast, TYPE_CHECKING imports, implicit-Optional defaults made explicit, and annotations widened (never guards removed) where mypy called a defensive isinstance check unreachable. No runtime behaviour change. mypy.ini: numpy and orjson are treated as Any (follow_imports=skip, also for stubs). numpy 2.3+ stubs use 3.12 `type` statements that mypy won't parse at python_version 3.10, and orjson is optional, so seeing its stubs made the result depend on whether it was installed.

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.

fix(vegas): pause for STATIC plugins where their turn falls in the strip (#651)
The static trigger peeked at the front of StreamManager's segment buffer, which continuous scrolling (the default) never advances -- it extends the strip with take_next_group() -- so the same first segment was examined on every frame. A STATIC plugin paused the scroll only if it was first, once, at startup; otherwise it scrolled past as ordinary content. Swap mode had the same problem for any STATIC plugin not first in its cycle. The render pipeline now records a marker (strip column, plugin id) for each STATIC plugin where the strip is built -- composition and every extension -- shifts the markers when the scrolled prefix is trimmed, and clears them on reset. The coordinator pauses when the scroll reaches the next marker: a tuple comparison per frame instead of a lock, a plugin lookup and a get_vegas_display_mode() call. take_next_group() no longer renders STATIC plugins' content. The pause calls display() under the plugin lock and is timed with the monotonic clock. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

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.

feat(vegas): render plugin content off the render thread, and keep it off the GIL when the panel needs it (#630)
DisplayManager.offscreen() gives a thread its own canvas, so Vegas renders every plugin's ticker content on its prefetch thread instead of pausing the scroll for canvas-bound plugins on the render thread. A render gate (src/common/render_gate.py, vegas_scroll.prefetch_gate, on by default with the GIL-releasing binding) lets the prefetch thread run Python only while the render thread waits in SwapOnVSync: on hdpi, frames 2+ refreshes late fell eightfold and late frames overall from 0.90% to 0.60%. See docs/OFFSCREEN_RENDERING.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> |

fix(vegas): smooth Vegas scroll pacing -- whole pixels per refresh, measured refresh, off-thread preview writes (#628)
Vegas scrolls a whole number of pixels per panel refresh, locked to SwapOnVSync, against the refresh the panel really holds (measured from swap gaps), instead of blending sub-pixel positions against the refresh cap. The web preview PNG is encoded off the render thread while scrolling, with writes ordered and retried. On hdpi, late frames fell from 6.3% to 0.7%. See docs/SCROLL_PERFORMANCE.md.

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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(run): drop a redundant comment Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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.

refactor: delete dead Python code in the core (and stop storing Wi-Fi passwords) (#608)
* refactor(plugins): remove the no-op PluginHealthMonitor Its monitor loop did nothing (`if callbacks: pass`), register_health_check had no callers and api_v3.health_monitor was never read by any route. The 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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`. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(vegas): remove unused config update, boundary finder and refresh VegasModeConfig.update had no callers outside its own tests (the coordinator rebuilds the config with from_config on a change); geometry.find_item_boundary and StreamManager._refresh_plugin_content had no callers at all. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(run): drop the debug block that pretended to import the plugin system In debug mode run.py put src/plugin_system itself on sys.path and printed "Plugin system import successful" without importing anything. Nothing imports plugin_system modules by bare name, so the path entry did nothing either. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: delete tests that test nothing - test/plugins/test_{basketball_scoreboard,calendar,clock_simple, odds_ticker,soccer_scoreboard,text_display}.py skip everywhere the named plugins are not installed, including CI (LEDMATRIX_PLUGINS_DIR holds only 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test: expect one plugin_last_update success stamp after update_all_plugins EveryStampRecordsACompletion required at least two success-path stamps; the second was update_all_plugins, removed as test-only. The worker and synchronous paths share the remaining stamp in _execute_update_now, and the check that every stamp calls _note_update_completed is unchanged.

fix: settings the display ignored, a memory leak, and the plugin card handler (#605)
* fix(errors): stop affected_plugins growing without bound Each repeat of an error pattern appended every plugin in the time window to the pattern's list again, so a plugin failing in a loop grew the display process's memory without limit: 3,000 errors from three plugins reached 2.5 million entries. Keep the list unique. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 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.

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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(changelog): note plugin asset, action and inline handler guards Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(config): use the shared core-key list in the last three private copies StartupValidator warned "Plugin 'auto_update' is enabled but not found" on every display start with auto-update or a dim schedule on; the reserved plugin-id check missed auto_update, sync, location and the rest; and ConfigManager's (uncalled) orphan cleanup would have deleted display, schedule and auto_update. All three now read src/core_config_keys.py, which also gains CORE_SECRETS_KEYS for the github/youtube secrets sections. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(web): partial JSON saves to /config/main change only what they send A JSON body with one field reset every checkbox in the sections it touched: the MQTT bridge's brightness slider turned off disable_hardware_pulsing, inverse_colors, show_refresh_rate and use_short_date_format, and a timezone-only save turned off web-UI autostart and weekly auto-updates. Missing-means-unchecked now applies only to form posts: form-encoded bodies and the v3 forms, which mark themselves with a hidden __form_section input. Also on the config routes: - vegas_min/max_cycle_duration no longer match the generic *_duration rule, so they stop landing in display_durations and a blank one no longer rejects the whole Display save; - saving from the Raw JSON editor calls start_setup_if_needed like the General form, so enabling auto-update there finishes its setup; - the schedule and dim-schedule POSTs accept the per-day days.<day> shape their GETs return, as well as the flat form keys. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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) Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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'. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(install): what install_service.sh installs; verify script port; no sudo for --help install_service.sh installs and starts ledmatrix, ledmatrix-web and the update-verify units, not only ledmatrix.service (systemd/README.md, README.md). MIGRATION_GUIDE presented 'sudo install_service.sh --help' as a harmless check; it now shows --help without sudo and warns what a real run does. SSH_UNAVAILABLE_AFTER_INSTALL: verify_installation.sh checks the web interface on port 5000. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(changelog): note update-all, plugin system settings and script fixes Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(display): refuse settings the rgbmatrix library aborts on, on every board The library answers several settings with a NULL matrix or abort() rather than an error, so the display service crash-looped (Restart=on-failure) instead of reaching fallback mode: rows above 64, chain_length above 255 (uint8_t binding setter, documented as "no upper limit"), a misspelled hardware_mapping, and parallel 2-3 on a single-output mapping, reachable from the Display form on the default adafruit-hat(-pwm) mapping. #586 only guarded the Pi 5 subset. - src/matrix_support.py holds the rules for every board (Options::Validate ranges, binding integer types, mapping names and outputs from lib/hardware-mapping.c) plus the Pi 5 ones, and is the one source of the API's numeric ranges. - DisplayManager checks them before building options and raises MatrixSettingsRefused, so a hand-edited config falls back with a logged, reported reason. Emulator mode only warns. - The config API refuses them with a 400 naming the setting; combinations are checked against stored values but reported only when the request sets a field involved. - The hardware status file gains "cause" (settings/library/forced). The fallback log and Display banner give the Pi 5 rebuild hint only for a library failure instead of rebuild + gpio_slowdown advice for every failure; one Pi 5 slowdown recommendation (1-3, start at 1). - The Display form offers classic/classic-pi1 and orientation 90/270 and renders any other stored mapping selected with a warning, so an unrelated save no longer rewrites them; the API accepts 90/270. Audit findings F03, F16, F19, F21. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Audit findings F19, F20, F21. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(scripts): scroll_speeds.py recommends keys the resolver honours The ladder ended by telling users to set display_options.scroll_pixels_per_second. scroll_config ranks that key below the scroll_speed + scroll_delay pair, deliberately, and several plugin schemas default the pair into config, so the advised key was silently ignored (a schema-default 1/0.02 pair plus an advised 66 still resolved to 50 px/s). The advice is now the pair that selects the crisp speed exactly (pixels_per_frame every frame_hold/refresh seconds), explains that the pair outranks scroll_pixels_per_second, and gives the scoreboards' per-league scroll_settings.scroll_speed (px/s) form. Tests resolve the printed pair over a schema-default pair and check it lands on the advertised speed and hold. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(changelog): scroll model fixes Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(mqtt-bridge): brightness changes apply live and touch nothing else The display service's hot reload applies a saved brightness within a few seconds, and /config/main no longer resets other display settings on a brightness-only JSON body. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(changelog): automatic update hardening Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(config): rewrite PLUGIN_CONFIG_ARCHITECTURE for the v3 web UI It described web_interface_v2.py and index_v2.html (both gone), client-side form generation, one POST per field with {key, value}, and 'no nested objects'. The v3 UI renders plugin forms server-side from the schema (pages_v3 partial + plugin_config.html macros, nested sections and x-widgets), posts the whole form once, and save_plugin_config() merges onto the stored section, validates, splits x-secret fields and notifies the plugin. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(mqtt): brightness saves apply via hot reload and leave other settings alone The bridge README said brightness is applied on the display's next restart; the display controller's config hot reload applies it within seconds. It also now states that the bridge's partial JSON save changes only brightness (the /config/main merge fix in this change set). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(update): don't log pip's output from the health check's reinstall pip can echo a private index URL with embedded credentials; permission_utils redacts it, the stdlib-only verifier cannot, so it logs the exit code only. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(config): mark the plugin_system toggles as unused legacy keys auto_discover, auto_load_enabled and development_mode are read by nothing and leave the General tab in this change set (F40). CONFIG_REFERENCE said they were read by the plugin loader; PLUGIN_CONFIGURATION_GUIDE and the REST reference listed them as live settings. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(changelog): docs and developer tools group Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(web): legacy plugin-system toggles no longer count as a General save auto_discover, auto_load_enabled and development_mode have left the General form, so a post carrying only one of them is not a general-settings save and must not treat web_display_autostart and auto_update as unchecked. The plugin_system block itself is left as on main for the branch that reworks it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(changelog): config-save and plugin-config preparation fixes Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(claude): re-check matrix_support.py rules when the library submodule is bumped Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix: address Codacy findings on the core audit PR - plugin_manager.prepare_plugin_config: when the fallback legacy-boolean pass also fails, log a warning instead of a bare except/pass. - api_client.js: request() refuses any endpoint that is not a plain path under /api/v3 ("//host", backslashes, ".." or "." segments, whitespace, control characters) with INVALID_ENDPOINT before calling fetch(), and plugin ids are URL-encoded wherever they are put into a URL (also in the app-shell batch load). - test_update_all.js: pins both against the shipped client. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(web): check endpoint control characters without a control-character regex Codacy (ESLint no-control-regex, Biome noControlCharactersInRegex) flags the \x00-\x1f range in checkEndpoint's regex. Test the char codes instead; the endpoints refused are unchanged. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(auto-update): make the seed script executable on disk, not only in the index On Linux Repo.publish() commits with -a, which recorded scripts/run.sh as 100644 upstream because the seed file was never chmod +x. The pull 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.

perf(vegas): report the frame rate when it is worth reporting (#487)
Vegas logged an FPS line at INFO every five seconds for the whole of
every run. Measured over two hours on a rig: 1410 samples, 98.5% of them
within 10% of target. The 1.5% that were not included a reading of
8.6fps against a target of 60 -- a real stall, completely invisible
inside 1389 lines reading "59.6". INFO is now reserved for a shortfall,
the recovery from one, and a slow heartbeat so a healthy marquee still
shows a pulse. Scroll-progress tracing drops to DEBUG for the same
reason: it runs for the whole of every scroll and is what you turn debug
on to watch.
Three review findings, all fixed here.
1. Per-frame timing used the wall clock (critical). The loop sleeps the
remainder of each frame budget:
frame_elapsed = <now> - frame_started
time.sleep(max(0.0, frame_interval - frame_elapsed))
These devices have no RTC, so the clock jumps by however wrong boot
time was when NTP first syncs. A backward step makes frame_elapsed
negative, `frame_interval - frame_elapsed` then exceeds the whole
budget, and the render loop stalls for the size of the correction. A
forward step instead inflates the p99 and worst-frame figures this
telemetry exists to report. Both per-frame timestamps are monotonic
now. start_time stays wall-clock: it is only used for the iteration
duration report, where a human-readable clock is the point.
2. FPS health state reset every iteration. last_fps_health_log and
was_degraded were locals of run_iteration(), which is called once per
cycle. Starting at 0.0 against a monotonic clock, `due` was true on
the first sample of every iteration, so the 300s heartbeat degenerated
into one report per cycle -- reintroducing the noise this change is
about. A recovery that crossed an iteration boundary was never
reported either, since was_degraded had already gone back to False.
Both now live on the coordinator and reset in start().
3. The degraded threshold read as an off-by-one. 90% of target is
deliberate -- a marquee jitters constantly, so "anything below target"
would report forever and mean nothing -- but nothing said so, leaving
55fps-against-60 looking like a missed case. The constant now states
the band and gives that exact example.
Also drops two soccer logo PNGs that a `git add -A` had swept into the
first commit. They are unreferenced, unrelated to frame-rate telemetry,
and 210KB.
Verified: each fix mutation-checked -- restoring the wall clock on either
per-frame timestamp, or making the health state local again, fails the
new tests. 566 passed across the vegas, coordinator and scroll suites.

consolidate(perf): cut SD writes, log volume, and metrics churn (#486)
* fix(plugins): one bad metrics cache entry should not stop every plugin
Caught live on a rig: every plugin failing, once each, continuously.
ERROR - src.plugin_system.plugin_manager - plugin geochron operation failed:
ResourceMetrics.__init__() got an unexpected keyword argument
'consecutive_failures'
ERROR - ... plugin text-display operation failed: ...
ERROR - ... plugin news operation failed: ...
ERROR - ... plugin odds-ticker operation failed: ...
with /api/v3/health reporting plugin_system: not_initialized while the display
process itself kept running and updating the panel.
`consecutive_failures` is a plugin_health field, not a metrics one.
get_metrics() does ResourceMetrics(**cached), which raises TypeError on a
single unrecognised key, and that exception escapes into plugin_manager and is
reported per plugin. One malformed cache entry takes the whole plugin system
down.
How a health-shaped record came to sit under a plugin_metrics key on that
machine is not established, and I could not finish the diagnosis: the rig went
back into its EIO failure mode partway through -- SSH resetting pre-banner,
systemctl unexecutable -- while the web API kept answering from RAM. Checked
before that: the cache files on disk are correctly shaped and separate, and
CacheManager.get() returns the right record for each key, so it is not a live
key collision. A restored backup mixing two machines' caches is the likeliest
explanation, and that rig had one restored onto it.
Either way the loader should not be brittle enough for the answer to matter.
plugin_health already repairs its records field by field rather than trusting
what is on disk; this does the same. Known fields are kept, unknown ones are
dropped and named once in the log so a genuine schema change stays visible
rather than being silently discarded, and a non-mapping entry no longer raises.
Keeping the known fields matters: discarding the record wholesale would throw
away real call counts and timings because of an unrelated stray key.
Mutation-checked: restoring ResourceMetrics(**cached) fails 6 checks, dropping
the whole record fails the field-preservation check, and dropping unknown
fields silently fails the logging check. 28 tests pass across the resource
monitor and plugin health suites.
* perf(health): stop rewriting a health record on every healthy cycle
Every successful plugin update called record_success(), which persisted the
record unconditionally. In steady state the only fields that had changed were
total_successes and last_success_time -- a counter and a timestamp that
health_monitor surfaces for display and that nothing reads back after a
restart. Nothing alerts on the age of last_successful_update; it is carried in
the metrics dataclass and shown.
Measured on a rig running 24 plugins, all steady-state (0 consecutive
failures, circuit closed): a five-minute sample caught 22 health-file
rewrites, about 4.4 a minute or 6,300 a day. Each write is ~400 bytes through
cache_manager.set(), which writes a file per call, so each one costs a
filesystem block plus an ext4 journal write.
That lands on an SD card, where the unit of cost is an erase-block cycle
rather than the bytes involved, and where wear is what eventually kills the
card. Two cards have already failed on the other rig with the same
signature -- unreadable block device, EIO on exec, sshd unable to read its
host keys.
The circuit breaker still has to survive a restart, so the write is kept for
exactly the fields it is rebuilt from: consecutive_failures, circuit_state,
circuit_opened_time, half_open_start_time. A failure, a circuit opening and a
recovery are all still written the moment they happen. In-memory state is
updated every time either way, so the health API and web UI show what they
always did.
Tested: 100 healthy cycles now perform zero writes after the first, the
counters remain accurate in memory, and a failure, a recovery and a
half-open-to-closed transition each still reach disk. One test kills and
rebuilds the tracker from the cache to prove the breaker's state genuinely
survives what is no longer written.
Mutation-checked both ways: persisting unconditionally again fails the
steady-state test, and widening _DURABLE_FIELDS to include last_success_time
fails it too. The 46 existing health tests pass.

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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> 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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ui/code/session_01Udr6MfaFLUPhX5Fgo67Jf5 * 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. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> 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.

feat(vegas): make scroll stutter visible, and catch it in the act (#454)
* feat(vegas): make scroll stutter visible, and catch it in the act The loop reported only a mean FPS over a five-second window. At 120fps that is ~600 frames, so a 200ms freeze -- plainly visible on a marquee -- moves the average from 120.0 to 115.4 and reads as healthy. Stutter was literally unmeasurable. The FPS line now carries p99, the worst frame, and a hitch count. On the dev rig that immediately turned "it sometimes stutters" into a number: two freezes of 3.2s and 0.7s in twenty minutes, with every other frame under 81ms. Statistics say a stall happened but not what caused it, and by the time they are logged the stack is gone. So there is also a watchdog that dumps every thread's stack while the loop is still wedged. It is off unless LEDMATRIX_STALL_WATCHDOG is set to a threshold in seconds, since it prints a lot. Pointed at the 3.2s freeze it named the culprit on the first try: a plugin generating a 17,000px scroll image, logo PNG decode and all, synchronously on the render thread. The hitch threshold is relative to what frames actually cost, not to the configured target. The target is routinely set above what the panel can hold so vsync does the pacing; measured against that budget every ordinary frame counts as a hitch, and the first version of this counter duly reported 250 per window on a display running perfectly smoothly. The watchdog is owned by the coordinator, not created per iteration -- run_iteration is called repeatedly, so building one there would leak a thread each time. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Udr6MfaFLUPhX5Fgo67Jf5 * fix(vegas): let the watchdog see stalls that hold the GIL The watchdog only noticed a late heartbeat, which a whole class of freeze can never produce: if the loop is inside one long C call that holds the GIL, this thread cannot run during the stall, and by the time it does the loop has already checked in. On the dev rig that hid a recurring 3.2s freeze completely -- twenty minutes of watching produced one dump, for an unrelated 0.4s stall. What it can still observe is that its own sleep ran long. A badly overshot wait is now reported as a stall in its own right. The stacks are stale by then and the message says so, but knowing the freeze is GIL-holding is most of the diagnosis: it rules out lock contention and scheduling, and points at a single long C call. This also explains why lowering sys.setswitchinterval changed nothing -- the switch interval cannot preempt a C call that never releases the GIL. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Udr6MfaFLUPhX5Fgo67Jf5 * feat(vegas): report the worst frame, not just the mean The loop logged only a mean FPS over a five-second window. At 120fps that is ~600 frames, so a 200ms freeze -- plainly visible on a marquee -- moves the average from 120.0 to 115.4 and reads as perfectly healthy. Stutter was unmeasurable, which is why "it sometimes freezes" went unpinned for so long. Adding p99 and the worst frame turned that into a number immediately: on the dev rig, two freezes of 3.2s and 0.7s in twenty minutes with every other frame under 81ms. Not general slowness -- two rare, total stalls, which is a different problem with a different fix. Costs 0.96us per frame, about 0.012% of an 8.3ms frame. This replaces an earlier version that also shipped a stall watchdog and a hitch counter. The watchdog never found anything -- one dump in forty-five minutes, for an unrelated stall -- because it can only notice a late heartbeat, and the freeze happens in coordinator.start() before the frame loop begins beating. py-spy found the cause in one recording by sampling the process externally, which needs no code here. The hitch counter went with it: it needed a rolling median every frame, which was most of the cost, to produce a number the worst frame already tells you.

Nearest rank is ceil(n * fraction) - 1. Extracted so it can be tested directly rather than only through a five-second logging interval. Reported by CodeRabbit on the PR.

fix(vegas): stop the width cap emitting fragments and stale windows (#446)
* fix(vegas): stop the width cap emitting fragments and stale windows Two defects in the rotation that narrows an oversized plugin to its width budget. Both were found while investigating "cut off early / starts in the middle" reports and are the reason the cap is no longer on by default; they still bite anyone who sets one. A rotation's last window was whatever happened to be left over. Windows are placed by walking forward from the previous one, with nothing looking at the remainder, so a 1,840px stocks ticker against a 1,536px budget split 1,492 + 348 -- every other appearance showed seven seconds and cut. Absorb a remainder below half a budget into the window before it. That overruns the budget by at most half, which is the better trade: the budget guards against one plugin holding the panel for minutes, not against a 20% overshoot. The floor is measured against the budget rather than the panel because snapping to item boundaries already lands an ordinary window short of it -- a 512px budget over 182px-pitch items yields 348px windows, so an absolute floor merges windows that were never fragments. The stored offset also outlived the content it was recorded against. It was a pixel column, reused verbatim after the plugin re-rendered, so once anything ahead of it changed width the window pointed at unrelated items -- observed as news refreshing 9,793px -> 9,505px mid-rotation. Track the rotation as an index into the strip's item boundaries instead, since the Nth boundary survives a digit appearing in a price, and record alongside it what the offset indexes into: a row list, a boundary list, or a column in a gapless image. A mismatch restarts the rotation rather than reinterpreting the number, which also closes the case where one plugin's row index was read back as a pixel column after its content changed from several rows to one wide strip. Replaying the four plugins that actually hit the cap on a live 512px panel: no window is now a fragment, none exceeds 1.5 budgets, and every rotation still covers the whole strip. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Udr6MfaFLUPhX5Fgo67Jf5 * fix(vegas): apply the runt floor to the multi-row rotation too The floor only guarded the single-image path. I had reasoned the row path could not produce a runt because it wraps, which is wrong: wrapping only helps when the row wrapped to actually fits. Rows of 450, 450 and 100 against a 512px budget give the 100 a pass of its own -- two seconds against nine, which is the symptom this branch exists to remove. Reproduced before changing anything: pass 1: 450px pass 2: 450px pass 3: 100px A window may now overrun the budget while it is still shorter than the floor, bounded at the same 1.5 budgets the single-image path allows, so the short row is carried with its neighbour instead of standing alone. pass 1: 450px pass 2: 450px pass 3: 550px A next row too wide to absorb within that cap still leaves a short window standing -- rows of 900 and 100 keep alternating. Merging them would mean a window of nearly two budgets, and the rule that always shows an oversized first row already makes the same trade. Three regression tests: the reported shape, that the overrun stays bounded when a row cannot be absorbed, and that absorbing never drops a row from the rotation. The single-image path is untouched -- the four plugins that actually hit the cap on a live panel replay identically.

fix(vegas): stop capping plugin width by default (#445)
* fix(vegas): stop capping plugin width by default Vegas plugins read as "cut off early" or "starting in the middle". That was the per-plugin width budget, not the scroll engine: overflow_mode=rotate is designed to resume mid-content on each appearance, so the symptom was the feature working as specified. Measured over a 17-plugin fleet on a 512px panel, the cap was a bad trade. Only four plugins were ever wide enough to hit the 3.0 default -- leaderboard 11,518px, news 10,021px, odds-ticker 4,643px, hockey 1,508px. Weather is 650px and flights 512px; the cap never touched them or the other eleven. So it bought nothing on thirteen plugins while costing two visible faults on four: content entering mid-item (a news ticker started at column 6027 of its own strip), and a final rotation window of whatever happened to be left -- 348px of an 1,840px stocks ticker, seven seconds of panel time. Default max_plugin_width_ratio to 0 (uncapped), so every plugin contributes all of its content and is always entered at its beginning. The cap remains available, and vegas_max_width_screens still caps an individual plugin -- which is where the knob belongs, since a genuinely long ticker is a property of that plugin rather than of the fleet. Verified on a live 512px device: 327 budget crops in the preceding six hours, none after.

Vegas mode: reclaim dead space and pace the rotation (#423)
* Vegas mode: reclaim dead space and pace the rotation On a wide panel Vegas mode spent much of its time showing black. At 50px/s on a 512px display, one display width of blank is 10.2 seconds, which makes several long-standing behaviours expensive: - ScrollHelper prepended a full display width of black as an "initial gap", charged once per cycle — 10.2s of black at the start of every rotation. - Plugins without get_vegas_content() are captured off a full-display canvas, so their blank margins entered the ticker too. Measured: of-the-day drew 35px of "No Data" on a 512px canvas (92% blank), youtube-stats 142px of content with 185px of black either side. Only the scroll_helper path had any trimming. - Cycle transitions deliberately pushed a blank frame and then recomposed synchronously: 84ms at best, 4.8s at worst, every millisecond of it black. - buffer_ahead doubled as the cycle size, so a 21-plugin install showed 3 plugins per cycle and took ~7 cycles to come around. - separator_width was applied between every image rather than at plugin boundaries, so a per-row ticker like the F1 scoreboard (116 images, which it renders 4px apart internally) got a 32px chasm between each row — and the width budget didn't count those gaps, so the plugin quietly occupied far more of the panel than intended. Changes: - src/vegas_mode/geometry.py: numpy column-ink primitives shared by the trimmer and the audit tool, so the number reported is the number acted on. A Python per-column loop over a 17,000px strip is far too slow for the render path. - PluginAdapter trims every content path, not just scroll_helper. Only outer edges are cropped: interior blank columns are the plugin's own layout (logo left, score right) and closing them would corrupt the design. A plugin on a non-black background is inherently unaffected. - ScrollHelper.create_scrolling_image takes an explicit lead_gap, still defaulting to display_width so the many standalone-ticker callers are unchanged. Vegas passes lead_in_width (default 0). - Cycle end holds the last rendered frame instead of blanking, turning the recompose into a brief freeze rather than the panel switching off. - plugins_per_cycle (default 6) is split from buffer_ahead, which goes back to being only a prefetch low-water mark. - max_plugin_width_ratio (default 3x display width) caps one plugin's share of a cycle. Overflow is deferred, not discarded: a rotation offset advances each fetch so later rows appear on subsequent cycles. Single oversized images are cropped at a blank column so the cut misses glyphs. - Composition groups images by plugin: rows are joined by intra_plugin_gap (default 8) and separator_width applies only between plugins. The width budget now counts those gaps. - Plugin data updates no longer run on the Vegas render path. All new settings are user-configurable in Display -> Vegas Scroll, including min/max cycle duration and dynamic duration, which previously existed in code but were reachable only by hand-editing config.json. Measured with scripts/dev/vegas_audit.py on a 512x64 panel: mean ink coverage 42.7% -> 69.4% fully blank 5.9% -> 0% reads as empty 13.6% -> 0% worst blank stretch 4.8s -> 0s full rotation 414s -> 123s plugins per cycle 3 -> 6 Note the metric choice: a "fully blank" scan (>=95% black viewport) reported only 0.4% and badly understated the problem, because two full-width segments with mid-canvas content never fully blank the viewport — they hold it at ~28%. window_coverage_stats grades every viewport position by how much ink it carries, which is what tracks perceived dead time. Known remaining: cycle transitions still freeze ~3.5s while the next cycle is fetched. Fixing that needs background prefetch, which is deferred because the fallback-capture path mutates the shared display_manager.image and racing it against the render loop risks torn frames. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Drop unused Optional import from the vegas audit script Flagged by Codacy (F401). Any, Dict and List are all still used. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Align Vegas API bounds with validate(), fix audit config plumbing Both from review feedback on #423. The web API's accepted ranges disagreed with VegasModeConfig.validate(), which is what actually gates Vegas starting: scroll_speed 1-100 -> 1-200 (a slider value of 150 returned 400) separator_width 0-500 -> 0-128 target_fps 1-200 -> 30-200 buffer_ahead 1-20 -> 1-5 The three loose ones were the dangerous direction: the value saved with a 200, then VegasModeCoordinator.start() failed validation with only a log line, so the ticker silently never ran. The UI already matched validate() in all four cases, so the API was the odd one out. test_vegas_api_bounds_match_validate parses the numeric_fields map out of api_v3 and asserts every bound against validate(), plus that validate() accepts both endpoints and rejects just outside them, so these cannot drift apart again. That test immediately caught a missing upper bound on min_plugin_width, now added — unbounded it would drop every segment and leave a blank ticker. Separately, vegas_audit.py constructed PluginAdapter without the config, so it fell back to VegasModeConfig() defaults and would report trimming and width-budget behaviour that differed from the user's config.json. It now passes the loaded config exactly as the coordinator does. This is the same class of drift the explicit lead_gap and grouping arguments already guard against. Output is unchanged on a rig whose config matches the defaults. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Vegas mode: render plugins narrower, space rows by measured separation Trimming reclaims blank margins but cannot compact a layout that genuinely spans the display — a five-column forecast, a progress bar drawn at 100% width, a stat block with the panel's whole width between its elements. Those need the plugin to make different layout decisions, which means telling it the screen is narrower while it renders. DisplayManager.render_size() presents a smaller logical canvas for the duration of a Vegas content fetch, reusing the same _LogicalMatrix indirection double-sided mode already relies on so plugins see a consistent size from every accessor. Plugins that size themselves from matrix.width need no changes at all; one that wants to be explicit can read the new BasePlugin.get_vegas_render_width(). Width is a percentage so a single setting travels across panel sizes: vegas_scroll.render_width_pct globally, or vegas_width_pct in an individual plugin's config. Measured on a 512x64 panel with real data: ledmatrix-weather 1536px -> 576px (forecast becomes narrow cards) youtube-stats 353px -> 199px (2% blank left, so genuinely compact) geochron 453px -> 153px (ink density rises to 100%) ledmatrix-flights 950px -> 740px The youtube-stats figure is the clearest evidence the layout itself changed rather than being cropped: at full width the content had to be trimmed from 512px to 353px, whereas at 40% it arrives with almost no blank to reclaim. Row spacing is now measured rather than added. A flat gap gets it wrong in both directions at once — content drawn flush to its own edges ends up nearly touching (reported for recent sports scores, which sat 8px apart), while content already carrying wide margins gets pushed even further out. separation_gap() measures the blank each pair already has and adds only the shortfall, up to min_content_separation (default 24). intra_plugin_gap stays as a floor applied regardless. Two tests shipped in the previous commit encoded the old flat-gap arithmetic and are updated to the measured semantics, including one renamed to reflect that zero intra_plugin_gap alone no longer butts rows together. Also fixes a real bug found while testing: the harness display manager had no render_size(), and because the adapter catches broadly that surfaced as "no content" rather than an error, silently dropping five plugins. Added the context to VisualTestDisplayManager for parity, and _render_at() now degrades to a no-op on any display manager lacking it, so a third-party or older harness loses the narrowing rather than the content. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Vegas mode: end cycles before the wrap, keep the width budget honest Three fixes, the first a regression from lead_in_width defaulting to 0. get_visible_portion wraps: once scroll_position + display_width passes the end of the strip it fills the right of the frame from the *head* of the same strip. So the final display_width of travel showed the cycle's first plugin re-entering on the right while its last plugin exited on the left, and the recompose that followed replaced both at once. On a 512px panel at 50px/s that was 10.2s of two plugins on screen at once, ending in a hard cut — reported as the ticker "switching mid-scroll" from F1 to news. That used to be invisible because the strip began with a full display_width of blank, so the wrapped-in region was black. Removing that blank (it was 10s of dead panel per cycle) exposed the wrap. Cycles now end one display width earlier, before any wrapped content appears, clamped for strips no wider than the display so they don't complete instantly and spin the recompose loop. Verified on hardware: a 3936px strip now completes at 68.5s, exactly (3936 - 512) / 50. Second, auto_trim=False also skipped the width budget, which is an unrelated concern — turning off margin cropping should not let one plugin hold the panel for minutes. Seen in the field: the F1 scoreboard contributed 116 images and 14,848px untouched, giving a 33,821px cycle (11 minutes of content). The budget now applies regardless of trimming; with it restored that cycle is 6,362px. Third, the budget accounted for row gaps using the flat intra_plugin_gap while the compositor had moved to measured separation, so it under-counted by up to (min_content_separation - intra_plugin_gap) per row and a many-row plugin overran its cap. Both now use the same separation_gap() rule, and a test asserts the composed block fits the budget end to end rather than trusting the two paths to agree.

Caught on hardware: it killed the ledmatrix-stocks fetch, and because _fetch_plugin_content catches broadly that surfaced as the plugin silently contributing nothing for the cycle. Only reachable on the second or later pass of the rotating window over a single oversized image, which is why the existing tests missed it — they all exercised the first pass, where start is 0 and start + budget is comfortably inside the image. Added TestRotationAcrossMultipleCycles, which walks the window round several times and asserts content is never lost, plus direct coverage of find_blank_cut at and beyond the image edge. Both bounds now stop at width - 1 so neither direction can index past the end. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Only cut oversized segments at real gaps between items The width-budget crop snapped to the nearest blank column, and in rendered text the gap between two characters is a single column. So a cut routinely landed inside a word: the cycle showed "Wednesda" and the orphaned "y" turned up as a lone floating letter in the next cycle, positioned after whatever plugin happened to precede it. Measured on the clock-simple segment to confirm: its blank runs are [1, 1, 1, 1, 1, 8, 8] — five single-column letter gaps, every one of which find_blank_cut would happily have chosen. Cuts now only land in a run of at least min_cut_gap blank columns (default 6), which excludes letter spacing while still finding the gaps plugins put between items (the stocks ticker uses 32px, baseball 48px). Where no boundary falls inside the budget the cut waits for the next one and overruns, because splitting an item is worse than a slightly long segment. Continuous content is treated differently on purpose: an image with no internal gaps is a map or a chart, where any column is as good as another, so it is still cut to the budget exactly. The gap rule protects discrete items; letting a solid image escape the cap in its name would be wrong. blank_runs() is vectorised — 48ms for a 17,000px strip, against seconds for a per-column Python loop.

That is a visible flash mid-scroll, and it lines up with the flash reported at cycle transitions, when several plugins are fetched back to back. Suppression is now unconditional; the narrowing context stays separate because it is already a no-op at full width. Both contexts are reached through helpers that degrade to nullcontext when the display manager lacks them. That matters more than it looks: the adapter's handlers are deliberately broad, so an AttributeError from a missing context does not surface as an error — it surfaces as the plugin contributing nothing. Making the call unconditional without this turned 44 tests red for exactly that reason, all of them reporting lost content rather than the real cause. The test double now provides capture_mode and render_size too, so tests exercise the real contexts instead of silently taking the degraded path. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Vegas mode: one continuous strip instead of swapping cycles A cycle used to be a discrete strip that got replaced: motion stopped, every pixel was substituted at once, and the next group started with the viewport already full. That is the freeze, the flash and the jump. The strip is now extended rather than replaced. ScrollHelper gains append_content(), which adds items on the right without touching scroll_position or total_distance_scrolled, so motion continues and the next group simply arrives from the right. Because completion is measured against total_scroll_width, extending also defers completion — there is no longer a cycle boundary to see. drop_scrolled_prefix() reclaims what has gone past, keeping the strip bounded however long Vegas runs (observed 5,000-11,000px against an unbounded strip otherwise). It shifts total_distance_scrolled and total_scroll_width together so the completion arithmetic is unchanged, and refuses to run while the viewport is wrapping: wrapping reads the head of the strip into the right of the frame, so trimming the head there would visibly change the picture. A test caught that. Groups are prepared off the render thread. The constraint is that the canvas and the matrix proxy are process-wide mutable state, so narrowing or capturing through them from another thread would corrupt the frame the render loop is pushing. get_content() therefore takes offscreen_only: the background thread uses only paths that avoid the canvas, and anything needing it is marked and picked up on the render thread. That puts the expensive work (native renders of leaderboard and baseball cards, seconds each) in the background and leaves the cheap work (display capture, 40-600ms) in the foreground. DisplayManager's capture flag is now thread-local. As a shared flag, a background capture would have suppressed the render loop's own frame pushes for its duration, freezing the panel precisely when the point was to avoid a freeze. Canvas-bound plugins are drained one at a time rather than as a batch: six at once held the render thread for 1.75s. Drains are also spaced by two seconds while the lookahead is healthy, since taking them back to back turns one long stall into a run of short ones. When the strip is genuinely running short the throttle is ignored, because content matters more than smoothness there. Measured on hardware: zero cycle-complete swaps, drains landing 2-4s apart, lookahead holding at 1,200-3,500px, no errors. Set continuous_scroll false to restore the swap behaviour; the old path is intact. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Pace the Vegas frame loop adaptively: 31.5 -> 78.7 fps The loop slept a fixed frame_interval on top of however long the frame took, so at a measured 31.6ms per frame a flat 8ms of that was pure idle — a quarter of the budget spent not rendering. It now sleeps only the remainder of the budget. Measured on hardware: 31.5 fps to 78.7 fps sustained, with CPU going *down* from 150% to 127%. Scroll speed is unchanged at 49.9px/s against a configured 50, because motion is derived from elapsed time rather than frame count — this buys smoothness, not speed. Worth recording what the bottleneck was not: the per-frame render path measures 0.34ms in total (0.18ms for the numpy slice, 0.17ms for the dirty-tracking digest), which is a theoretical 2900 fps. Optimising any of that would have been wasted effort. The frame was idle, not busy. Also nices the prefetch thread. Its work is PIL and numpy that releases the GIL, so the scheduler can act on the priority, and without it the prefetch competes for the same cores as the render loop. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Sub-pixel scrolling: motion at the frame rate, not the pixel rate With integer positioning the number of distinct frames per second equals the scroll speed in px/s, however fast the loop renders. Measured at 50px/s and 78.7fps, 36% of frames were byte-identical: the extra frames cost work and bought no motion, and what was left was 50 discrete 1px steps a second. Two things were wrong with the pre-existing sub-pixel support. get_visible_portion never consulted sub_pixel_scrolling — it always took the integer path, so the flag and _get_visible_portion_subpixel were dead code. And that implementation needed scipy.ndimage.shift, which is not installed on the target devices (HAS_SCIPY is False there), so it would not have interpolated even if reached. Verified both: positions 1000.0 and 1000.5 produced identical frames either way. Blending is now wired up and implemented with numpy. Two details make it affordable: slice cached_array directly instead of building two PIL images only to convert them straight back (the naive version measured 15x the integer path), and use fixed-point uint16 multiply-add rather than float32, which suits the Pi's cores and gives finer weighting than the panel can resolve. Result 0.939ms against 0.237ms — 0.70ms added per frame, a 1065fps ceiling. Measured on hardware: 81.2 fps with blending on, against 78.7 with it off, so no cost within noise — and every frame is now a distinct position rather than one in three being a repeat. The trade is a slight horizontal softening of text, since each frame blends two positions. Set smooth_scroll false for maximum crispness. Also benchmarked and cleared as non-issues: extending the strip costs 9.4ms on an 11,000px strip and trimming 2.5ms, both under one frame at this rate. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Add overflow handling: keep ordered content whole instead of rotating a window The width budget split any oversized plugin by advancing a window each cycle. That is right for interchangeable items — news headlines, odds, stock prices — but wrong for ordered content: a league table showed ranks 1-6, then resumed at 7 two rotations later, which reads as out of order and out of context. Nobody needs rank 23 in a ticker; they need the top of the table, every time. overflow_mode chooses between them: rotate — advance a window each cycle so everything is seen eventually (unchanged default) truncate — always show the start and drop the rest, keeping ordered content coherent. Records no window state, so every pass starts at the top. Per-plugin vegas_overflow overrides the global setting, since one install has both kinds of plugin. Also adds per-plugin vegas_max_width_screens, so content that must stay whole can be given more room — or uncapped with 0 — without lifting the cap on every ticker. Applied on the test rig: f1-scoreboard and ledmatrix-leaderboard set to truncate, and baseball given 4.5 screens because it was showing 8 of 9 games when the whole slate needed only a little more room. Verified: F1 now reports "the first 10 of 116 ... the rest are not shown", baseball has dropped out of the budget log entirely, and stocks, odds-ticker and stock-news still rotate. Also corrects the crop log, which claimed "window advances next cycle" unconditionally and so misreported truncated crops. A test now pins the behaviour behind the message: truncate must leave no offset recorded. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KEZK1P1Q1fu5pcuVrkrCFZ * Stop Vegas mode showing last night's games as if they were live A game that was live in the evening was still being drawn as live the next morning. Two faults combined to freeze plugin visuals indefinitely. PR #291 added a call to plugin_adapter.invalidate_plugin_scroll_cache() so a plugin's own cached scroll image would be rebuilt from fresh data. That method was never implemented. hot_swap_content() wraps the call in a broad except, so every hot swap has raised AttributeError and been swallowed silently ever since — which is why the visuals it was meant to keep fresh never were. Continuous scrolling then removed the only path that reached it at all: should_recompose() and hot_swap_content() are called from the non-continuous branch of run_frame(), and continuous_scroll defaults to True. So on a default install the pending-update flags were set by the update tick, never consumed, and grew without bound. Together these froze content completely, because refetching is not enough on its own: the sports plugins' get_vegas_content() regenerates only "if the cache is empty", so take_next_group() kept receiving the same picture however often it asked. Fixed by: - Implementing invalidate_plugin_scroll_cache(). It covers both layouts — a helper directly on the plugin (stocks, news, odds-ticker) and one owned by a scroll-display manager (the sports scoreboards, which is the shape that produced this bug) — and clears cached_image and cached_array together, since the array is the image's numpy mirror. - Adding StreamManager.invalidate_pending_updates() and calling it from the continuous branch. It only drops the caches; the plugin recomposes when it next comes round in the rotation. process_updates() is wrong here: it refetches synchronously and merges into the active buffer that continuous mode bypasses, and hot_swap_content() rebuilds and repositions the whole strip, which is the freeze-and-jump this mode exists to avoid. Tests assert the fix rather than the implementation: 14 of the 17 new tests fail without it. Includes the wiring itself, since the regression was a call that was simply absent, and a check that the scroll position is untouched so this cannot regress into the swap's visible jump. All Vegas suites pass (355 tests). test_display_controller_vegas_tick.py still cannot be collected off-device for want of rgbmatrix, identically with and without this change.

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. |

Fix inconsistent Vegas scroll transition gaps caused by plugin-baked padding (#384)
* Strip plugin-baked scroll padding when capturing content for Vegas mode Plugins that build their own ticker image via ScrollHelper.create_scrolling_image() (or that manually pad both ends for a clean standalone loop) carry a solid-black margin up to display_width wide on one or both edges. Vegas mode already adds its own configurable gap around every item, so leaving that margin in place stacked an extra, uncontrolled blank stretch on top of separator_width for whichever plugin took the ScrollHelper-capture path — producing inconsistent transition gaps between modules compared to plugins that provide content natively via get_vegas_content(). _get_scroll_helper_content() now detects and crops any such margin before handing the image to the Vegas render pipeline, so every plugin's gap is governed solely by vegas_scroll.separator_width regardless of which capture path produced its content. * Address CodeRabbit nitpick: warn on double-edge padding crop, add unit tests Logging a double-edge match at warning level (vs. info for a single edge) makes it easy to spot an unexpected crop in the field, since two edges matching at once is a much stronger signal of genuine baked-in padding than one edge coinciding with real all-black content. Also adds test/test_vegas_plugin_adapter.py covering _strip_scroll_padding's branch logic: leading-only, trailing-only, both-edges, no-match, degenerate all-black, missing/undersized display_width, and the info-vs-warning log level. * Add type hints and docstring to test _solid helper (CodeRabbit nitpick) --------- Co-authored-by: Claude <noreply@anthropic.com> |

Vendor library globals — htmx is injected by <script> before these extension files load; ESLint lints files in isolation and doesn't know. Fix: add /* global htmx */ to htmx-sse.js and htmx-json-enc.js. 2. Cross-file globals — showNotification is defined as window.showNotification in app.js/notification.js but called bare in app.js and error_handler.js. ESLint doesn't connect window.X = Y with a bare call to X. Fix: add /* global showNotification */ to app.js and error_handler.js. 3. Forward-reference window.* functions — in array-table.js, checkbox-group.js, and custom-feeds.js, functions like removeArrayTableRow are called early inside event-handler closures but assigned to window.* later in the file. At runtime this works (the handler fires after the assignment), but ESLint sees the bare name at the call site. Fix: change bare calls to window.removeArrayTableRow(this) etc. so the reference is explicit and ESLint-safe.

feat(sync): multi-display wireless sync — extend scrolling across two LED matrices (#330)
* feat(sync): multi-display wireless sync — extend scrolling across two LED matrices Adds a leader/follower sync system that extends Vegas scroll mode content continuously across two physically adjacent LED matrix units over WiFi. Architecture: - Leader broadcasts scroll position via UDP at ~90fps; follower renders the offset slice of the same image at 60fps using dead reckoning to absorb UDP jitter (smooth, stutter-free motion) - At each cycle transition the leader sends the composed scroll image via TCP (PNG-compressed ~15–40KB) so both displays render pixel-identical content regardless of plugin data timing differences - Auto-discovery via UDP subnet broadcast — no IP configuration required - Heartbeat watchdog (6s timeout) falls back to standalone if peer goes offline Key files: - src/common/sync_manager.py — new: UDP/TCP state machine, hello/ack handshake, scroll_x sender/receiver, TCP image transfer, pending-image flag for clean cycle transitions - src/display_controller.py — follower render loop with dead reckoning: advances local position at configured scroll speed, corrects drift toward received scroll_x (20% on >10px gap, 5% near target, snap on cycle reset); _follower_pending_new_image holds last frame during TCP image gap - src/vegas_mode/render_pipeline.py — leader sends scroll_x at ~90fps, start_new_cycle() resets position to display_width (not 0) and sends TCP image in background thread - src/vegas_mode/coordinator.py — set_sync_manager() / set_update_callback() wiring; defers hot-swap recompose while sync is active - web_interface/blueprints/api_v3.py — sync config save endpoint, GET /api/v3/sync/status for live status polling - web_interface/templates/v3/partials/display.html — Multi-Display Sync section: role selector (Standalone/Leader/Follower), position (Left/Right of leader, follower only), UDP port, live status indicator - config/config.template.json — sync block: role, port, follower_position Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(sync): address PR review findings - sync_manager: replace Optional[callable] with proper Callable types from typing; tighten set_on_new_cycle/set_on_scroll_image/set_on_follower_connected signatures to match their actual callback signatures - sync_manager: log a one-shot warning when send_frame produces a packet exceeding the 65000-byte UDP cap instead of silently dropping it - display_controller: correct stale comment in _send_follower_frame (was "30fps / PNG encode/decode"; actual behavior is ~90fps raw RGB) - display.html: guard setInterval with window.syncStatusInterval to prevent duplicate pollers if the script runs more than once - display.html: replace innerHTML with DOM node creation + textContent for status icon/text to avoid inserting API-derived values via innerHTML Skip: time.time() → monotonic and self.config staleness are pre-existing issues not introduced by this PR. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(sync): address second round of PR review findings - sync_manager: guard TCP image receive against OOM — validate length against 10 MB cap before allocating; log and close on invalid length - display_controller: _follower_gated_update now allows update_display() through when the leader is offline (is_follower_active() == False) so the display recovers normally when falling back to standalone mode - coordinator: normalize a standalone SyncManager to None in set_sync_manager() so the render pipeline never treats a no-op manager as an active one - coordinator: derive _UPDATE_TICK_FRAMES from target_fps * 4 instead of the hardcoded 500 so the ~4s cadence holds at any configured FPS - render_pipeline: replace bare except/pass on blank-frame push with logger.exception() so failures are visible in logs Skip: config.template.json comments — JSON does not support inline comments. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(sync): address third round of PR review findings - sync_manager: use 'with socket.socket(...)' in send_scroll_image so the TCP socket is always closed even if connect/sendall raises - sync_manager: add _scroll_image_lock to serialize all reads/writes to _on_scroll_image and _pending_scroll_image between _image_server_loop and set_on_scroll_image, eliminating the lost-delivery race; callback is invoked outside the lock to avoid holding it during user code - sync_manager: validate scroll image dimensions (max 100000×256) and catch DecompressionBombError before img.load() in _image_server_loop - sync_manager: log socket close exceptions at debug level in stop() instead of silently passing - sync_manager: replace hardcoded /tmp/ with tempfile.gettempdir() for STATUS_FILE (atomic write was already in place) - sync_manager: check _RAW_MAGIC first in _follower_recv_loop routing so magic-tagged frames are always identified correctly regardless of size Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(sync): address fourth round of PR review findings - sync_manager: log INCOMPATIBLE error only on state transition (guard with prev_state != LeaderState.INCOMPATIBLE) so repeated hello packets from an incompatible follower don't spam the log - sync_manager: replace O(n²) bytes concatenation in TCP image receive loop with bytearray + extend() for linear-time accumulation Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(sync): suppress Codacy false positives - display_controller: rename local var 'sh' to 'scroll_h' so Codacy's pattern matcher doesn't confuse it with the 'sh' shell library - sync_manager: add '# nosec B104' to all socket.bind("") calls — binding to all interfaces is intentional (UDP broadcast reception and TCP image server must accept connections from any local interface) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(sync): add nosec B104 to socket creation lines for Codacy Codacy attributes the bind-to-all-interfaces finding to the socket.socket() creation lines (140, 439) rather than the .bind() calls. Added # nosec B104 there too so the suppression is seen at the line Codacy reports.

fix(vegas): eliminate plugin re-appearance at scroll cycle boundaries (#327)
* fix(vegas): eliminate plugin re-appearance at scroll cycle boundaries The Vegas scroll image is wider than the display. scroll_helper marks a cycle complete only after total_distance_scrolled >= total_scroll_width + display_width, meaning it keeps scrolling for an extra display_width of pixels after all content has exited left. During that extra travel the scroll_position wraps back to ~0 and the first plugin re-enters from the right - visible for ~2-3 seconds as a plugin partially displaying before the next one starts. render_pipeline.render_frame(): end the cycle the moment total_distance_scrolled >= total_scroll_width (the natural wrap point), before any second-pass content becomes visible. Push a blank frame immediately on detection so hardware never shows a frozen content snapshot while start_new_cycle() recomposes (~100 ms). display_manager.py: add capture_mode() context manager. When active, update_display() and the canvas clear in clear() skip the hardware write, preventing plugins that call update_display() internally from flashing on the matrix during off-screen content capture inside start_new_cycle(). plugin_adapter.py: wrap all plugin.display() calls in _capture_display_content() and _trigger_scroll_content_generation() with capture_mode() so the fallback capture path never produces hardware output. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(vegas): tighten exception handling in clear() and blank-frame push display_manager.clear(): replace bare except/pass on the three hardware Clear() calls with (RuntimeError, OSError) and a logger.error() so failures are visible in logs rather than silently swallowed. Still non-fatal — the PIL image buffer is already black before these calls, so the next update_display() will push clean content regardless. render_pipeline.render_frame(): replace broad except/pass in the blank-frame push with (ImportError, ValueError, TypeError, MemoryError) and a logger.error() that includes display dimensions for context. update_display() already handles its own hardware errors internally. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(vegas): catch OSError and RuntimeError in blank-frame push Image.new() can raise OSError in some PIL environments and hardware libraries may surface RuntimeError on I/O failures. Add both to the exception tuple alongside the existing ImportError/ValueError/TypeError/ MemoryError so no boundary failure escapes the local handler.

fix: reduce CPU usage, fix Vegas refresh, throttle high-FPS ticks (#304)
* fix: reduce CPU usage, fix Vegas mid-cycle refresh, and throttle high-FPS plugin ticks Web UI Info plugin was causing 90%+ CPU on RPi4 due to frequent subprocess calls and re-rendering. Fixed by: trying socket-based IP detection first (zero subprocess overhead), caching AP mode checks with 60s TTL, reducing IP refresh from 30s to 5m, caching rendered display images, and loading fonts once at init. Vegas mode was not updating the display mid-cycle because hot_swap_content() reset the scroll position to 0 on every recomposition. Now saves and restores scroll position for mid-cycle updates. High-FPS display loop was calling _tick_plugin_updates() 125x/sec with no benefit. Added throttled wrapper that limits to 1 call/sec. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: address PR review — respect plugin update_interval, narrow exception handlers Make _tick_plugin_updates_throttled default to no-throttle (min_interval=0) so plugin-configured update_interval values are never silently capped. The high-FPS call site passes an explicit 1.0s interval. Narrow _load_font exception handler from bare Exception to FileNotFoundError | OSError so unexpected errors surface. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(vegas): scale scroll position proportionally on mid-cycle hot-swap When content width changes during a mid-cycle recomposition (e.g., a plugin gains or loses items), blindly restoring the old scroll_position and total_distance_scrolled could overshoot the new total_scroll_width and trigger immediate false completion. Scale both values proportionally to the new width and clamp scroll_position to stay in bounds.

fix(vegas): refresh scroll buffer on live score updates (#299)
* fix(vegas): refresh scroll buffer when plugins report live data updates should_recompose() only checked for cycle completion or staging buffer content, but plugin updates go to _pending_updates — not the staging buffer. The scroll display kept showing the old pre-rendered image until the full cycle ended, even though fresh scores were already fetched and logged. Add has_pending_updates() check so hot_swap_content() triggers immediately when plugins have new data. Fixes #230 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(vegas): scope hot-swap to visible segments; use monotonic clock 1. Replace has_pending_updates() with has_pending_updates_for_visible_segments() so hot_swap_content() only fires when a pending update affects a plugin that is actually in the active scroll buffer (with images). Avoids unnecessary recomposition when non-visible plugins report updates. 2. Switch all display-loop timing (start_time, elapsed, _next_live_priority_check) from time.time() to time.monotonic() to prevent clock-stepping issues from NTP adjustments on Raspberry Pi.

fix(vegas): keep plugin data and visuals fresh during Vegas scroll mode (#291)
* fix(vegas): keep plugin data and visuals fresh during Vegas scroll mode Plugins using ESPN APIs and other data sources were not updating during Vegas mode because the render loop blocked for 60-600s per iteration, starving the scheduled update tick. This adds a non-blocking background thread that runs plugin updates every ~1s during Vegas mode, bridges update notifications to the stream manager, and clears stale scroll caches so all three content paths (native, scroll_helper, fallback) reflect fresh data. - Add background update tick thread in Vegas coordinator (non-blocking) - Add _tick_plugin_updates_for_vegas() bridge in display controller - Fix fallback capture to call update() instead of only update_data() - Clear scroll_helper.cached_image on update for scroll-based plugins - Drain background thread on Vegas stop/exit to prevent races Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(vegas): address review findings in update pipeline - Extract _drive_background_updates() helper and call it from both the render loop and the static-pause wait loop so plugin data stays fresh during static pauses (was skipped by the early `continue`) - Remove synchronous plugin.update() from the fallback capture path; the background update tick already handles API refreshes so the content-fetch thread should only call lightweight update_data() - Use scroll_helper.clear_cache() instead of just clearing cached_image so cached_array, total_scroll_width and scroll_position are also reset Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Chuck <chuck@example.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |

Feature/vegas scroll mode (#215)
* feat(display): add Vegas-style continuous scroll mode Implement an opt-in Vegas ticker mode that composes all enabled plugin content into a single continuous horizontal scroll. Includes a modular package (src/vegas_mode/) with double-buffered streaming, 125 FPS render pipeline using the existing ScrollHelper, live priority interruption support, and a web UI for configuration with drag-drop plugin ordering. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * feat(vegas): add three-mode display system (SCROLL, FIXED_SEGMENT, STATIC) Adds a flexible display mode system for Vegas scroll mode that allows plugins to control how their content appears in the continuous scroll: -

Add VegasDisplayMode enum to base_plugin.py with backward-compatible mapping from legacy get_vegas_content_type() - Add static pause handling to coordinator with scroll position save/restore - Add mode-aware content composition to stream_manager - Add vegas_mode info to /api/v3/plugins/installed endpoint - Add mode indicators to Vegas settings UI - Add comprehensive plugin developer documentation Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas,widgets): address validation, thread safety, and XSS issues Vegas mode fixes: - config.py: align validation limits with UI (scroll_speed max 200, separator_width max 128) - coordinator.py: fix race condition by properly initializing _pending_config - plugin_adapter.py: remove unused import - render_pipeline.py: preserve deque type in reset() method - stream_manager.py: fix lock handling and swap_buffers to truly swap API fixes: - api_v3.py: normalize boolean checkbox values, validate numeric fields, ensure JSON arrays Widget fixes: -

select-dropdown.js: guard global registry access - slider.js: add escapeAttr for attributes, fix null dereference in setValue Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): improve exception handling and static pause state management coordinator.py: - _check_live_priority: use logger.exception for full traceback - _end_static_pause: guard scroll resume on interruption (stop/live priority) - _update_static_mode_plugins: log errors instead of silently swallowing render_pipeline.py: - compose_scroll_content: use specific exceptions and logger.exception - render_frame: use specific exceptions and logger.exception - hot_swap_content: use specific exceptions and logger.exception Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): add interrupt mechanism and improve config/exception handling - Add interrupt checker callback to Vegas coordinator for responsive handling of on-demand requests and wifi status during Vegas mode - Fix config.py update() to include dynamic duration fields - Fix is_plugin_included() consistency with get_ordered_plugins() - Update _apply_pending_config to propagate config to StreamManager - Change _fetch_plugin_content to use logger.exception for traceback - Replace bare except in _refresh_plugin_list with specific exceptions - Add aria-label accessibility to Vegas toggle checkbox - Fix XSS vulnerability in plugin metadata rendering with escapeHtml Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): improve logging, validation, lock handling, and config updates - display_controller.py: use logger.exception for Vegas errors with traceback - base_plugin.py: validate vegas_panel_count as positive integer with warning - coordinator.py: fix _apply_pending_config to avoid losing concurrent updates by clearing _pending_config while holding lock - plugin_adapter.py: remove broad catch-all, use narrower exception types (AttributeError, TypeError, ValueError, OSError, RuntimeError) and logger.exception for traceback preservation - api_v3.py: only update vegas_config['enabled'] when key is present in data to prevent incorrect disabling when checkbox is omitted Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): improve cycle advancement, logging, and accessibility - Add advance_cycle() method to StreamManager for clearing buffer between cycles - Call advance_cycle() in RenderPipeline.start_new_cycle() for fresh content - Use logger.exception() for interrupt check and static pause errors (full tracebacks) - Add id="vegas_scroll_label" to h3 for aria-labelledby reference - Call updatePluginConfig() after rendering plugin list for proper initialization Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): add thread-safety, preserve updates, and improve logging - display_controller.py: Use logger.exception() for Vegas import errors - plugin_adapter.py: Add thread-safe cache lock, remove unused exception binding - stream_manager.py: In-place merge in process_updates() preserves non-updated plugins - api_v3.py: Change vegas_scroll_enabled default from False to True Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): add debug logging and narrow exception types - stream_manager.py: Log when get_vegas_display_mode() is unavailable - stream_manager.py: Narrow exception type from Exception to (AttributeError, TypeError) - api_v3.py: Log exceptions when reading Vegas display metadata with plugin context Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): fix method call and improve exception logging - Fix _check_vegas_interrupt() calling nonexistent _check_wifi_status(), now correctly calls _check_wifi_status_message() - Update _refresh_plugin_list() exception handler to use logger.exception() with plugin_id and class name for remote debugging Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(web): replace complex toggle with standard checkbox for Vegas mode The Tailwind pseudo-element toggle (after:content-[''], etc.) wasn't rendering because these classes weren't in the CSS bundle. Replaced with a simple checkbox that matches other form controls in the template. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * debug(vegas): add detailed logging to _refresh_plugin_list Track why plugins aren't being found for Vegas scroll: - Log count of loaded plugins - Log enabled status for each plugin - Log content_type and display_mode checks - Log when plugin_manager lacks loaded_plugins Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): use correct attribute name for plugin manager StreamManager and VegasModeCoordinator were checking for plugin_manager.loaded_plugins but PluginManager stores active plugins in plugin_manager.plugins. This caused Vegas scroll to find zero plugins despite plugins being available. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): convert scroll_speed from px/sec to px/frame correctly The config scroll_speed is in pixels per second, but ScrollHelper in frame_based_scrolling mode interprets it as pixels per frame. Previously this caused the speed to be clamped to max 5.0 regardless of the configured value. Now properly converts: pixels_per_frame = scroll_speed * scroll_delay With defaults (50 px/s, 0.02s delay), this gives 1 px/frame = 50 px/s.

Shows frame count in each 5-second interval. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): improve plugin content capture reliability - Call update_data() before capture to ensure fresh plugin data - Try display() without force_clear first, fallback if TypeError - Retry capture with force_clear=True if first attempt is blank - Use histogram-based blank detection instead of point sampling (more reliable for content positioned anywhere in frame) This should help capture content from plugins that don't implement get_vegas_content() natively. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): handle callable width/height on display_manager DisplayManager.width and .height may be methods or properties depending on the implementation. Use callable() check to call them if needed, ensuring display_width and display_height are always integers. Fixes potential TypeError when width/height are methods. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): use logger.exception for display mode errors Replace logger.error with logger.exception to capture full stack trace when get_vegas_display_mode() fails on a plugin. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): protect plugin list updates with buffer lock Move assignment of _ordered_plugins and index resets under _buffer_lock to prevent race conditions with _prefetch_content() which reads these variables under the same lock. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): catch all exceptions in get_vegas_display_mode Broaden exception handling from AttributeError/TypeError to Exception so any plugin error in get_vegas_display_mode() doesn't abort the entire plugin list refresh. The loop continues with the default FIXED_SEGMENT mode. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(vegas): refresh stream manager when config updates After updating stream_manager.config, force a refresh to pick up changes to plugin_order, excluded_plugins, and buffer_ahead settings. Also use logger.exception to capture full stack traces on config update errors. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * debug(vegas): add detailed logging for blank image detection * feat(vegas): extract full scroll content from plugins using ScrollHelper Plugins like ledmatrix-stocks and odds-ticker use ScrollHelper with a cached_image that contains their full scrolling content. Instead of falling back to single-frame capture, now check for scroll_helper.cached_image first to get the complete scrolling content for Vegas mode. * debug(vegas): add comprehensive INFO-level logging for plugin content flow - Log each plugin being processed with class name - Log which content methods are tried (native, scroll_helper, fallback) - Log success/failure of each method with image dimensions - Log brightness check results for blank image detection - Add visual separators in logs for easier debugging - Log plugin list refresh with enabled/excluded status Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * feat(vegas): trigger scroll content generation when cache is empty When a plugin has a scroll_helper but its cached_image is not yet populated, try to trigger content generation by: 1. Calling _create_scrolling_display() if available (stocks pattern) 2. Calling display(force_clear=True) as a fallback This allows plugins like stocks to provide their full scroll content even when Vegas mode starts before the plugin has run its normal display cycle. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix: improve exception handling in plugin_adapter scroll content retrieval Replace broad except Exception handlers with narrow exception types (AttributeError, TypeError, ValueError, OSError) and use logger.exception instead of logger.warning/info to capture full stack traces for better diagnosability. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix: narrow exception handling in coordinator and plugin_adapter - coordinator.py: Replace broad Exception catch around get_vegas_display_mode() with (AttributeError, TypeError) and use logger.exception for stack traces - plugin_adapter.py: Narrow update_data() exception handler to (AttributeError, RuntimeError, OSError) and use logger.exception Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix: improve Vegas mode robustness and API validation - display_controller: Guard against None plugin_manager in Vegas init - coordinator: Restore scrolling state in resume() to match pause() - api_v3: Validate Vegas numeric fields with range checks and 400 errors Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> --------- Co-authored-by: Chuck <chuck@example.com> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com> |
