Codebase audit: fix shipping bugs, remove verified-dead code, repair doc drift, add regression guards (#438)
* fix(web): implement delete_cached so the font catalog cache actually invalidates
api_v3.py's font upload/delete handlers import delete_cached from
web_interface.cache, but the function was never defined. The surrounding
except ImportError silently swallowed the failure, so the fonts_catalog
cache entry survived uploads/deletes and newly uploaded fonts did not
appear until the TTL expired or the service restarted.

* fix(web): remove dead weather/stocks partial routes that returned 500
The partial dispatcher still routed 'weather' and 'stocks' to loaders
rendering v3/partials/weather.html and stocks.html — templates that no
longer exist since weather and stocks became store plugins. Requesting
either partial raised TemplateNotFound, which the catch-all turned into
a 500. No template or JS references these partials (the only 'weather'
hit in the front end is a plugin-store category filter option), so the
branches and both loader functions are removed; unknown partials now
fall through to the existing 404 handler.

* fix(deps): align contradictory psutil/Flask-Limiter/freetype-py pins
requirements.txt's optional-install comment recommended psutil>=5.9,<6.0
while web_interface/requirements.txt hard-requires >=6.0,<7.0 — anyone
following the comment ends up with an unsatisfiable pair. The comment now
recommends the same range the web interface requires (all psutil APIs
used — Process, boot_time, cpu_percent, disk_usage, virtual_memory — are
stable in 6.x). Flask-Limiter gains the same <4.0 cap in both files and
freetype-py the same >=2.5.1 floor.

* fix(config): add template keys the code already reads
display.hardware gains pixel_mapper_config, row_address_type,
multiplexing and panel_type (read at display_manager.py with these exact
fallbacks — users on non-standard panels previously had no way to
discover them from the template). vegas_scroll gains
frame_based_scrolling and scroll_delay, the only two of its 27 keys the
template omitted (read in src/vegas_mode/config.py). plugin_system gains
development_mode, which the web UI reads and writes but the template
never declared.
Every added value is byte-identical to the code-side .get() fallback, so
ConfigManager._migrate_config() merging these keys into existing user
configs cannot change behavior on any installed device.

* fix(scripts): repair broken sys.path setup in utility scripts
clear_cache.py and download_nba_logos.py pointed sys.path at a 'src'
directory relative to the script's own folder (scripts/utils/src and
scripts/src — neither exists), so both crashed on import; they now insert
the project root and import via the src package like the other scripts.
debug_web_manual.py resolved 'project root' to scripts/debug/ instead of
two levels up. fix_nhl_cache.sh is removed: it used Python docstring
syntax in a bash script and invoked clear_nhl_cache.py, which does not
exist anywhere in the repo — it cannot ever have worked in its current
location.

* docs: correct stale file:line references and the loader-fallback contradiction
CLAUDE.md and .cursorrules disagreed about plugin-directory fallback
behavior; the code (SchemaManager.get_schema_path) probes plugins/
BEFORE plugin-repos/, and the main discovery path has no fallback at
all — both files now describe the real behavior, preferring symbol names
over line numbers so the references rot slower. REST_API_REFERENCE.md
pointed at app.py:144/:607 for mounts that live at :199/:799 and counted
92 routes where there are 94. PLUGIN_ARCHITECTURE_SPEC.md's historical
banner gains a note that its example imports
(src/plugin_system/base_classes/*_plugin.py) never shipped — the real
base classes are src.base_classes.sports.SportsCore and
src.base_classes.hockey.Hockey.

* docs: fix broken links, phantom script references, and stale CI description
Repairs every broken relative link in active docs (targets renamed or
archived long ago: PLUGIN_DEVELOPMENT.md -> PLUGIN_DEVELOPMENT_GUIDE.md,
API_REFERENCE.md -> REST_API_REFERENCE.md, PLUGIN_STORE_USER_GUIDE.md ->
PLUGIN_STORE_GUIDE.md, plugin_docs/ dir, TROUBLESHOOTING_QUICK_START.md,
and MIGRATION_GUIDE's README link that silently resolved to the docs
index instead of the project README). Replaces commands invoking scripts
that do not exist (scripts/update_stats.py, validate_registry.py,
check_updates.py, fix_permissions.sh) with the real tooling, and
rewrites HOW_TO_RUN_TESTS.md's CI section, which described a
security-audit workflow that was never committed and a pytest workflow
'queued to land' that landed long ago as test.yml.

* docs: complete the docs index and refresh the web interface file tree
docs/README.md's own policy says every page must be linked from the
index, yet five weren't — including the entire skin system
(SKIN_SYSTEM.md, CREATING_SKINS.md), ADAPTIVE_LAYOUT.md,
plugin-safety-harness.md and SPORTS_UNIFICATION.md. Each is now listed
in the section it belongs to, and PLUGIN_ARCHITECTURE_SPEC.md is marked
historical in the index (the doc itself already carries the banner).
web_interface/README.md's static/v3 tree showed only app.css/app.js;
it now reflects the actual contents.

* chore: remove dead modules confirmed unused in-repo and across all store plugins
- src/common/cli.py: imports a 'ledmatrix_common' package that exists
nowhere (not in this repo, any requirements file, or the plugin
monorepo), so it cannot ever have run; its README section claimed
scripts/dev/* used it, which was also untrue.
- src/web_interface/logging_config.py: zero callers — the web app uses
web_interface/logging_config.py (a different module), and nothing
imports the src copy.
- handle_errors decorator in src/web_interface/error_handler.py: zero
call sites (the module's response helpers stay — they are used).
- ConfigManager.get_clock_config(): reads a 'clock' config key that no
longer exists anywhere; only caller was its own unit test.
Deliberately kept despite zero in-repo callers: DisplayError,
src/common/config_helper.py and display_helper.py — all documented as
plugin-facing API (docs/PLUGIN_ERROR_HANDLING.md, src/common/README.md),
and third-party plugins outside the official monorepo cannot be
enumerated. Verified against a fresh clone of ledmatrix-plugins (43
plugins): zero references to any removed symbol.

* chore: remove manager-era NBA test files and one-off debug scripts
The four test_nba_*.py files imported nba_managers, leaderboard_manager
and odds_manager — top-level modules deleted when sports displays became
plugins — inside try/except blocks that swallowed the ImportError, so
they passed while exercising nothing. test_nba_data_structure.py and
debug_nba_api.py (a diagnostic script living in test/) made live ESPN
API calls rather than testing repo code. None were enrolled in CI.
scripts/debug/direct_fix_imports.py and check_imports.py were one-shot
artifacts that edited/inspected a hardcoded ~/LEDMatrix/web_interface/
app.py to fix an import problem solved long ago; nothing references
them.

* chore: remove generate_report.py, which aggregates artifacts of CI jobs that do not exist
The script's only function is to merge JSON artifacts
(bandit/semgrep/pip-audit/safety/gitleaks results) produced by a
security-audit workflow that was never committed —
.github/workflows/ has no such jobs, so there is nothing for it to
aggregate and no way to run it usefully. Its siblings stay:
prove_security.py and audit_plugins.py both run standalone (verified),
and .codacy.yml stays because the Codacy service (README badge) reads it
server-side without a workflow file.

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

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

* chore(deps): remove packages nothing imports, declare direct imports, move mypy to test deps
Removed from requirements.txt: python-socketio, python-engineio,
websockets, websocket-client — zero imports anywhere in this repo, and
the one store plugin that needs Socket.IO (ledmatrix-music) declares it
in its own requirements.txt, which the plugin store installs. Removed
the same quartet plus timezonefinder, geopy, google-auth-oauthlib,
google-auth-httplib2, google-api-python-client, unidecode, icalevents,
python-dateutil, flask-wtf and the werkzeug pin from
web_interface/requirements.txt — all leftovers from the deleted built-in
weather/calendar/music displays (flask-wtf was doubly dead: app.py
explicitly disables CSRF and sets csrf=None). scripts/
install_dependencies_apt.py, which mirrors these lists for the
first-time installer, drops the same packages.
Added: urllib3 (imported directly in four core modules), jinja2 and
markupsafe (imported directly in pages_v3.py) — previously reachable
only as transitives. mypy moves from runtime requirements to
requirements-test.txt.
Verified in a fresh venv: all four requirements files co-install, pip
check is clean, the full CI-enrolled suite (907 tests) and a Flask boot
smoke pass with the trimmed dependency set.

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

* docs(code): document deliberate duplicates instead of merging them
The audit surfaced several near-duplicate implementations that turned
out to be either deliberate forks or behaviorally different — merging
any of them would risk changing behavior on installed devices, so each
now carries an explicit comment stating the relationship:
- VisualDisplayManager: headless fork of DisplayManager; header now
lists the ~15 mirrored methods and warns that DisplayManager changes
must be mirrored.
- normalize_abbreviation: LogoDownloader's version (called directly by
nine scoreboard plugins) replaces filesystem-unsafe characters;
LogoHelper's strips spaces. Logo filenames on existing installs
depend on both behaviors staying put.
- The two PluginTestBase classes: the shipped one is plugin-author
API, the repo's own richer harness lives in test/plugins/ — now
cross-referenced.
Also verified (no change needed): ConfigManager's backup/rollback
methods genuinely delegate to AtomicConfigManager, and SportsCore
already delegates _read_bdf_native_size to FontManager.

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

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

* docs: archive the custom-icons status report, cross-link config docs, document assets/
PLUGIN_CUSTOM_ICONS_FEATURE.md was a 'What Was Implemented' status
report duplicating the actual guide (PLUGIN_CUSTOM_ICONS.md) — moved to
docs/archive/ per the docs index's own policy. The overlapping
plugin-config docs keep their content but PLUGIN_CONFIG_ARCHITECTURE.md
now states up front which doc is canonical for which purpose.
assets/README.md is new and load-bearing: assets/stocks, weather,
news_logos and broadcast_logos have zero references in this repo's code,
which makes them look deletable — but store plugins (ledmatrix-stocks,
ledmatrix-weather, news, odds-ticker) resolve those exact paths at
runtime against the install directory. The README records that evidence
so a future cleanup doesn't break installed plugins.

* test: add regression guards for the bug classes fixed in this PR
Three lightweight static checks, all enrolled in CI's unit-test
allowlist along with the new web-cache test:
- test_template_targets.py: every literal render_template() target must
exist (would have caught the weather/stocks partial 500s at commit
time).
- test_widget_scripts.py: every widget JS file must be script-included
in base.html or explicitly allowlisted with a reason (would have
caught the unloaded time-picker/file-upload-single/plugin-file-manager
widgets), and allowlisted files must NOT be included (prevents the
example widget from shadowing the real color-picker).
- test_doc_links.py: relative markdown links in active docs must
resolve (docs/archive/ exempt).
Each guard was verified to fail against the pre-PR tree and pass now.

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.

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(plugin-harness): add no-op process_deferred_updates to test double (#391)
The safety harness's VisualTestDisplayManager (base of BoundsCheckingDisplayManager) doesn't implement process_deferred_updates(), which 5 first-party ledmatrix-plugins call unconditionally between set_scrolling_state() and their scroll-position update: news, odds-ticker, ledmatrix-leaderboard, stock-news, and ledmatrix-stocks. Any of them fails the harness with AttributeError the moment it's touched (surfaced when ledmatrix-plugins#177 had to add a local hasattr guard in ledmatrix-stocks just to pass CI). Add the method as a no-op, mirroring the existing "no-op for testing" pattern already used for set_scrolling_state, so these plugins render under the harness without every touching PR needing its own guard. |

fix: Codacy security fixes, CVE dependency bumps, and code quality cleanup (#331)
* fix(deps): bump minimum versions to address CVEs Pillow 10.4.0 → 12.2.0: CVE-2026-40192 (DoS via FITS decompression bomb), CVE-2026-25990 (OOB write via PSD image), CVE-2026-42311/42308/42310 requests 2.32.0 → 2.33.0: CVE-2026-25645 (temp file security bypass), CVE-2024-47081 (.netrc credentials leak) werkzeug 3.0.0 → 3.1.6: CVE-2023-46136, CVE-2024-49766/49767, CVE-2025-66221, CVE-2026-21860/27199 (DoS, path traversal, safe_join bypass) Flask 3.0.0 → 3.1.3: CVE-2026-27205 (session data caching info disclosure) spotipy 2.24.0 → 2.25.2: CVE-2025-27154, CVE-2025-66040 python-socketio 5.11.0 → 5.14.0: CVE-2025-61765 pytest 7.4.0 → 9.0.3: CVE-2025-71176 (insecure temp dir handling) Updated in requirements.txt, web_interface/requirements.txt, plugin-repos/starlark-apps/requirements.txt, and plugin-repos/march-madness/requirements.txt. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix: resolve Pylint errors in executor, data service, and odds call Rename TimeoutError to PluginTimeoutError in plugin_executor.py to avoid shadowing the built-in; no external callers affected. Remove dead try/except in BackgroundDataService.shutdown: executor.shutdown() never accepted a timeout kwarg so the try branch always raised TypeError. Simplify to a direct shutdown(wait=wait) call. Remove is_live kwarg from odds_manager.get_odds() call in sports.py; BaseOddsManager.get_odds() has no such parameter. The live update interval is already encoded in the update_interval_seconds argument passed alongside. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix: MD5→SHA-256, shellcheck warnings, and broken doc links config_service.py: replace MD5 with SHA-256 for config change detection; same semantics (equality comparison), no stored hashes affected.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix: remove unused imports and bare exception aliases (pyflakes F401/F841) Remove unused imports across 86 files in src/, web_interface/, test/, and scripts/ using autoflake. No logic changes — only dead import statements and unused names in from-imports are removed. Also remove bare exception aliases where the variable is never referenced in the handler body: - src/cache/disk_cache.py: except (IOError, OSError, PermissionError) as e - src/cache_manager.py: except (OSError, IOError, PermissionError) as perm_error - src/plugin_system/resource_monitor.py: except Exception as e - web_interface/app.py: except Exception as read_err 86 files changed, 205 lines removed, 18 pre-existing test failures unchanged.

Vendor library globals — htmx is injected by <script> before these extension files load; ESLint lints files in isolation and doesn't know. Fix: add /* global htmx */ to htmx-sse.js and htmx-json-enc.js. 2. Cross-file globals — showNotification is defined as window.showNotification in app.js/notification.js but called bare in app.js and error_handler.js. ESLint doesn't connect window.X = Y with a bare call to X. Fix: add /* global showNotification */ to app.js and error_handler.js. 3. Forward-reference window.* functions — in array-table.js, checkbox-group.js, and custom-feeds.js, functions like removeArrayTableRow are called early inside event-handler closures but assigned to window.* later in the file. At runtime this works (the handler fires after the assignment), but ESLint sees the bare name at the call site. Fix: change bare calls to window.removeArrayTableRow(this) etc. so the reference is explicit and ESLint-safe. Also guard the updateSystemStats call in app.js reconnectSSE: the function is called but defined nowhere in the codebase. Guard with typeof check so it won't throw ReferenceError if the reconnect path is hit. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(js): resolve Biome lint warnings across 9 JS files noUnusedVariables (catch bindings → optional catch syntax): - app.js, file-upload.js, timezone-selector.js: } catch (e) { → } catch { ES2019 optional catch binding; e was unused in all three handlers noUnusedVariables (dead assignments): - app.js: remove const data= in display SSE stub (handler does nothing yet) - api_client.js: remove const timeoutId= (setTimeout ID never used to cancel) - custom-feeds.js: remove const oldIndex= (getAttribute result never read) - schedule-picker.js: remove const compactMode= (never used in HTML build) - select-dropdown.js: remove const icons= (icons not yet rendered in options) noPrototypeBuiltins: - day-selector.js: DAY_LABELS.hasOwnProperty(x) → Object.prototype.hasOwnProperty.call(DAY_LABELS, x) Safe form that works even on null-prototype objects useIterableCallbackReturn: - file-upload.js, notification.js: forEach(x => expr) → forEach(x => { expr; }) — forEach ignores return values; implicit return from arrow body was misleading htmx-sse.js is a vendor extension file with old-style var/== patterns that are correct for it; 18 Biome issues suppressed via Codacy API rather than modifying the vendor source. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(security): escape user input in raw HTML responses in pages_v3.py plugin_id comes directly from the URL path (/partials/plugin-config/<plugin_id>) and was interpolated into an HTML fragment without escaping. A crafted URL like /partials/plugin-config/<script>alert(1)</script> would inject that tag into the DOM via the HTMX partial response. Fix: wrap all user-controlled values in markupsafe.escape() before embedding in raw HTML strings. Affects the plugin-not-found 404 response and both error 500 responses in the plugin config partial. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix: address Bandit B108/B110 across production code B110 (try/except/pass): - display_controller.py: narrow 'except Exception' to 'except AttributeError' for get_offset_frame() — plugins not having this optional method is the expected case, not all exceptions - config_manager.py: B110 already resolved by the earlier removal of the dead secrets-loading block (the except/pass was inside it) - All other except/pass blocks in src/ and web_interface/ are intentional (last-resort recovery, best-effort fallbacks, non-critical startup probes).

feat: add dev preview server and CLI render script (#264)
* fix(web): wire up "Check & Update All" plugins button window.updateAllPlugins was never assigned, so the button always showed "Bulk update handler unavailable." Wire it to PluginInstallManager.updateAll(), add per-plugin progress feedback in the button text, show a summary notification on completion, and skip redundant plugin list reloads. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * feat: add dev preview server, CLI render script, and visual test display manager Adds local development tools for rapid plugin iteration without deploying to RPi: - VisualTestDisplayManager: renders real pixels via PIL (same fonts/interface as production) - Dev preview server (Flask): interactive web UI with plugin picker, auto-generated config forms, zoom/grid controls, and mock data support for API-dependent plugins - CLI render script: render any plugin to PNG for AI-assisted visual feedback loops - Updated test runner and conftest to auto-detect plugin-repos/ directory Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(dev-preview): address code review issues - Use get_logger() from src.logging_config instead of logging.getLogger() in visual_display_manager.py to match project logging conventions - Eliminate duplicate public/private weather draw methods — public draw_sun/ draw_cloud/draw_rain/draw_snow now delegate to the private _draw_* variants so plugins get consistent pixel output in tests vs production - Default install_deps=False in dev_server.py and render_plugin.py — dev scripts don't need to run pip install; developers are expected to have plugin deps installed in their venv already - Guard plugins_dir fixture against PermissionError during directory iteration - Fix PluginInstallManager.updateAll() to fall back to window.installedPlugins when PluginStateManager.installedPlugins is empty (plugins_manager.js populates window.installedPlugins independently of PluginStateManager) - Remove 5 debug console.log statements from plugins_manager.js button setup and initialization code Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(scroll): fix scroll completion to prevent multi-pass wrapping Change required_total_distance from total_scroll_width + display_width to total_scroll_width alone. The scrolling image already contains display_width pixels of blank initial padding, so reaching total_scroll_width means all content has scrolled off-screen. The extra display_width term was causing 1-2+ unnecessary wrap-arounds, making the same games appear multiple times and producing a black flicker between passes.
