ChuckandClaude Opus 5 ad5bc4b819 perf(sports): LRU-bound the decoded logo cache (#559)
SportsCore._logo_cache was a plain dict keyed by team abbreviation with no
eviction. Its entries are not file bytes but decoded RGBA thumbnails sized to
display*1.5 -- roughly 36KB on a 256x64 panel, more for wide wordmarks -- and
assets/sports/ncaa_logos ships 307 of them. A plugin that walked a full league
held the whole league resident: about 11-18MB per manager instance, and a league
runs three (live/recent/upcoming) that each keep their own cache, so the same
logos were duplicated across them.

On the 1GB Pi 3B+ this was measured on, one board was sitting at 439MB resident
with ~290MB available, so tens of megabytes of duplicated league logos is real
money. Bounded to 64 entries, which holds a full "other games" cycle (on the
order of 20 games, 40 teams) without thrashing while capping the cache well
below a 307-team league.

Eviction is LRU rather than clear-when-full, using the OrderedDict/popitem
pattern the neighbouring caches in this codebase already use (_IMAGE_CACHE_MAX,
_FIT_CACHE_MAX, _TEXT_WIDTH_CACHE_MAX). That ordering matters: the logos on
screen right now are precisely the ones that must not be discarded, so a cache
hit moves the entry to the end.

ChuckandClaude Sonnet 5 fb3b293ace fix(plugins): let a plugin ask to be polled faster while it has live content (#555)
* fix(plugins): let a plugin ask to be polled faster while it has live content

Reported: "the football plugin with live games only updates the live game in
progress if I restart the display."

The data path was never the problem. NFLLiveManager fetches ESPN with no cache,
SportsLive.update() refreshes current_game in place when the game IDs are
unchanged, and the scorebug redraws from the game dict every frame -- which is
why the reporter's logs look healthy.

The problem is cadence. _get_plugin_update_interval() read only the manifest's
static update_interval, football's manifest pins that to 60, and the plugin's
own live_update_interval (15s) was invisible to the scheduler. Measured on a rig
during the fourth quarter of the game in the report:

    23:21:49  23:22:50  23:23:50  23:24:50  23:25:50   <- exactly 60s apart

A clock and score up to a minute stale during a two-minute drill reads as a
frozen panel, and a restart is the one moment it is ever current.

A single static number cannot say "every 15 seconds while a game is on, every 15
minutes in July", and only the plugin knows which is true. get_update_interval()
lets it say so per tick; returning None means "no opinion" and the existing
manifest/config resolution applies, so every plugin that predates this is
unaffected.

Requests are clamped to MIN_DYNAMIC_UPDATE_INTERVAL (5s): a plugin returning 0
would otherwise be re-entered on every tick of the render loop, busy-waiting
against its own API. A hook that raises or returns a non-number is ignored
rather than propagated -- a scheduler that fails on one plugin's bug stops
updating all the others.

Deliberately NOT changed: the manifest still beats config in the static path.
That looked like the obvious fix -- user config being silently ignored -- until
checking a real rig, where football and baseball both carry update_interval 3600
in config against a manifest 60, and weather 1800 against 60. Those values are
stale precisely because nothing has been honouring them; making config win would
have slowed three plugins by 60x, turning a one-minute lag into an hour. The
dynamic hook makes the flip unnecessary. There is a test pinning the current
precedence with that reasoning attached.

Full suite: 4,283 passed, 68 skipped.

* test(plugins): drive the real scheduler, not just the interval resolver

test_plugin_dynamic_update_interval.py asserts that
_get_plugin_update_interval() returns the number the plugin asked for. That is
not the same claim as "the plugin gets updated more often", and the gap between
those two is exactly where the original bug lived: the plugin knew it wanted
15s, said so in live_update_interval, and nothing downstream acted on it.

So this ticks the real run_scheduled_updates() through a simulated hour and
counts dispatches. Against pre-fix core it reports "10 updates in 10 minutes of
a live game" -- the 60s manifest cadence, matching what was measured on a rig
during the reported game. Against the fix it reports ~40.

Also pins the regression that would be worse than the bug: an idle hour must
still be ~60 updates, not 240. Asking for the live interval year-round would
poll ESPN four times a minute all summer.

Scope note, since it is easy to over-read this fix: the *switch* display path
already refreshed the manager immediately before drawing, via
_try_manager_display() -> _ensure_manager_updated(), which honours the manager's
own 15s interval. So a switch-mode card was already <=15s stale at draw time
before this change. What this fixes is the background cadence, which is what
live-priority detection, Vegas content and scroll preparation all read.

Full suite: 4,288 passed, 68 skipped.

* fix(plugins): reject bool and -inf hook results in dynamic interval

get_update_interval() ran bool through float() (bool is an int subclass,
so True/False became 1.0/0.0) and only checked for +inf, not -inf. Both
cases landed on the MIN_DYNAMIC_UPDATE_INTERVAL floor by coincidence
instead of falling back to the static/manifest interval as invalid
input should.

ChuckandClaude Opus 5 8da13f02f8 chore: ignore team logos fetched at runtime (#551)
logo_downloader.py and LogoHelper write into assets/sports/<league>_logos/
whenever a plugin meets a team whose logo is not on disk. Those directories are
also tracked -- 209 NCAA logos and 153 soccer ones ship with the repo -- so
every rig accumulates untracked files nobody intended to commit. This checkout
had 62; hdpi shows the same.

The cost is not the files, it is that a permanently dirty `git status` trains
everyone to ignore the one signal that says a checkout is not what you think it
is. That is how a stale tree sat unnoticed on a rig for hours until a restart
surfaced four sports plugins that could no longer import.

Ignoring a directory does not untrack what is already in it, so the logos that
ship keep shipping -- verified: 209 and 153 still tracked, no deletions in the
diff. Only new downloads are hidden.

Adding a logo on purpose stays possible and is what the escape hatch in the
comment documents. It is also rare: the last deliberate addition was #415, four
named NCAA logos a plugin needed, and `git log` finds no other in a year. So the
common case is noise and the rare case is explicit, which is the right way round.

Untracked files: 62 -> 0.

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

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

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

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

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

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

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

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

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

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

ChuckandClaude Opus 5 12f3790994 fix(install): render the systemd units from their templates, not from heredocs (#547)
* fix(install): render the systemd units from their templates, not from heredocs

The installers carried their own inline copies of units that also exist as
templates under systemd/, and the copies drifted.

install_service.sh renders ledmatrix.service from the template correctly, then
wrote ledmatrix-web.service from a heredoc that predated it -- missing
Wants=network-online.target, RestartSec=10, SyslogIdentifier, CacheDirectory,
CacheDirectoryMode and Environment=USE_THREADING=1. install_web_service.sh had
a third copy, and install_wifi_monitor.sh a fourth, that one already differing
from its template (syslog where the template says journal).

startup_validator.py compares the installed unit against the template, so a
rig installed this way warned on every boot -- and the remedy the warning
names, "re-run scripts/install/install_service.sh", reinstalled the same stale
copy. The warning could never clear. Reproduced on a live rig running exactly
that unit.

All three installers now render systemd/*.service through the same placeholder
substitution. The template gains a __USER__ placeholder rather than hardcoding
User=root, because the web interface runs as whoever installed it.

That last point was a second, independent cause of a permanent warning: the
validator substituted a fixed "root", so any non-root install reported drift
forever. It now reads User= from the installed unit -- an install-time
decision, not something the template dictates -- and compares everything else
strictly. first_time_install.sh already reads the installed User= the same way.

Tests cover a non-root web unit not warning, a genuinely changed directive in
that unit still warning, the User= fallback, and a grep-based guard that no
installer under scripts/install/ contains an inline unit body. That guard is
what found the install_wifi_monitor.sh copy.

* fix(install): escape sed replacements, use mktemp, and make render failures fatal

Address CodeRabbit findings on install_service.sh, install_web_service.sh and
install_wifi_monitor.sh:

- Values interpolated into each script's sed expression (project root path,
  username) were not escaped, so a value containing &, \ or the | delimiter
  would corrupt the rendered systemd unit. Add a shared
  sed_escape_replacement() helper in the new scripts/install/lib_systemd_render.sh
  (sourced by all three scripts) and apply it to every sed replacement.
- install_service.sh rendered the main and web units to the predictable path
  /tmp/ledmatrix.service.tmp before installing them -- a symlink/TOCTOU race
  (CWE-377). Use mktemp for both, with a trap to clean up on exit.
- install_service.sh treated a missing template as a mere warning and then
  checked only whether a unit already existed at the destination before
  enabling/starting it, so a render failure could silently fall back to
  enabling a stale, previously-installed unit. Both unit blocks now exit
  non-zero on a missing template or a failed render.

Also rename the ambiguous loop variable `l` to `line` in
test/test_systemd_unit_drift.py (Ruff E741); ruff isn't wired into any CI
workflow in this repo today, so this isn't currently CI-blocking, but the
rename is trivial and correct regardless.

* test(install): cover sed_escape_replacement against sed-special characters

CodeRabbit asked for regression coverage using a project path containing an
ampersand; the earlier commits on this branch already fixed the escaping,
mktemp usage, and enable/start-on-fatal-render-failure findings, and the
l->line rename was already applied -- this closes the one remaining gap.

ChuckandClaude Opus 5 2df273ecfc fix(web): default web_display_autostart to true, as the installer already does (#556)
start_web_conditionally.py read the flag with
`config_data.get("web_display_autostart", False)`, so a config that simply
lacked the key got no web interface. Both config/config.template.json and
first_time_install.sh ship the key as true, so the code default contradicted
the shipped default in two places: absence means an older or hand-edited
config, not a request to stay down.

The failure mode was silent in the worst way. The "not starting" path exits 0,
so `systemctl status ledmatrix-web` reported the unit as successfully started
while nothing was listening on the port, and the only trace was one journal
line saying the flag was "false or not set" -- which reads as a deliberate
setting rather than a missing key.

Also start the web interface when config.json is missing or unparseable,
instead of exiting. The web interface is how a config gets created and
repaired, so a broken config is exactly when the user needs it most; leaving
it down means there is no way back in. Only an explicit false/off disables
autostart now, and the disabled message says "explicitly disabled" so the
journal distinguishes a real setting from a default.

ChuckandClaude Opus 5 a29c84208e fix(scroll): advance whole pixels per frame, not per wall-clock second (#545)
* fix(scroll): advance whole pixels per frame, not per wall-clock second

Smooth motion is not a frame-rate property, and measuring it as one is why
this survived three rounds of fixes. odds-ticker's frame timing is excellent
-- 100.0 fps, 10.00ms median, 0% stalls, worst in-scroll frame 19.95ms -- and
it still visibly stuttered.

What the eye judges is whether the strip advances the same number of whole
pixels on every presented frame. update_scroll_position derived position from
scroll_speed * delta_time and get_visible_portion truncated it with int(), so
jitter in delta_time decided which side of a pixel boundary the position
landed on. The live windows show why that matters: a rock-steady 100.0 fps
whose individual frames still range 5.6ms to 15.2ms, which at 100 px/s is
0.57px to 1.44px of movement.

Run the measured frame times through the real helper and 5.8% of frames
advance 0 or 2 pixels instead of 1 -- about six hitches a second. A frame that
moves nothing followed by one that jumps two is exactly what micro-stutter
looks like.

It is worst at a crisp speed, which is the part that stings: at 100 px/s on a
100Hz panel the accumulator sits exactly on integer boundaries, so
sub-millisecond jitter flips it either way and the motion beats at around
50Hz. Snapping to the crisp ladder fixes the average and the wall clock then
throws away the per-frame uniformity the ladder was bought for.

So when scroll_config snaps to a crisp speed it now also puts the helper in
fixed-step mode: each presented frame advances exactly pixels_per_frame and no
clock is consulted. 100% of frames move by the same amount, whatever the
jitter.

This is only correct because SwapOnVSync blocks until the panel has taken the
frame, which makes the frame count a truer clock than time.time(). Before the
swap was locked to vsync it would have run at whatever speed the loop spun at.
Related: frame-based mode used to step discretely and was converted to
elapsed-time accumulation earlier in this series, because its threshold
comparison flipped on jitter. That was right for the code as it stood -- but
it treated the symptom, replacing a broken discrete step with a smooth-looking
accumulator instead of asking why a wall clock was involved at all.

Non-crisp speeds keep pacing off time, and set_scroll_speed() clears the fixed
step so a legacy caller changing speed is not silently ignored.

Trade-off worth naming: speed is now tied to the presentation rate rather than
to real time. If the loop cannot keep up with the panel the scroll runs slow
rather than jumping to catch up. That is the better failure -- uniform motion
at a slightly wrong speed beats correct average speed with a hitch six times a
second -- and a loop that cannot hit the resolved rate is a measurement
problem for the crisp ladder, not something to paper over with uneven steps.

* test(scroll): make the time-based pin actually pin something

Review caught that test_time_based_stepping_is_what_it_replaces could pass
against perfectly uniform motion, and it was right.

update_scroll_position sets last_update_time on its way through, so the very
first call sees a delta_time of zero and moves nothing in time-based mode.
_advances counted that synthetic frame, which put a guaranteed zero in every
histogram -- enough on its own to satisfy "uneven > 0". The test asserting the
defect exists would have passed after the defect was gone.

The first call is now primed and discarded, and the assertion is a proportion
rather than "more than zero": against these frame times the old path misses
roughly one frame in twenty, so 1% is well below the real rate and far above
anything a stray frame could produce.

Re-measured with the artefact removed, the numbers in the PR description are
unchanged: 5.85% of frames uneven before (114 zero-advance and 120 double
frames in 4000), 0.00% after.

Also fills in the docstrings the review flagged: everything in the new test
file, plus three pre-existing one-liners in scroll_config that the diff
touched.

ChuckandClaude Opus 5 1198615d19 test: install PyYAML so the starlark route tests can load the plugin (#546)
Tests has been red on main since #535. All 13 failures in
test/web_interface/test_starlark_pixlet_routes.py are the same
ModuleNotFoundError: No module named 'yaml'.

The test loads plugin-repos/starlark-apps/tronbyte_repository.py by path --
deliberately, "the way the blueprint does", since the core web blueprint
really does exec that plugin module -- and the plugin imports yaml.

Nothing is undeclared. The plugin's own requirements.txt already pins
PyYAML>=6.0.2, and on a real rig the plugin store installs it. CI installs
only requirements.txt and requirements-test.txt, so a core test that reaches
into a plugin gets none of the plugin's dependencies.

PyYAML goes in the test requirements rather than the core ones because it is
not a core dependency: nothing in src/ or web_interface/ imports yaml. This is
the same shape as the psutil entry directly above it -- a package the core does
not require, installed so a test can exercise a real path instead of a stub.

Verified locally: with yaml available the file goes from 13 failures to 64
passing. (One unrelated failure remains on Windows only, where os.geteuid does
not exist.)

ChuckandClaude Opus 5 f8e2e89edc refactor(sports): put the scoreboards on the shared scroll resolver (#542)
* refactor(sports): put the scoreboards on the shared scroll resolver

Eight sports scoreboards -- afl, baseball, basketball, football, hockey,
lacrosse, nrl, soccer -- scrolled through this module's own pacing while the
other eleven scrolling plugins went through src/common/scroll_config. Two
implementations of the same job, and this one was on the losing side of every
difference.

It never called set_scrolling_state. Two consequences, both of which this
release's work was about:

- The frame hold is applied through that call, so a speed the crisp ladder
  could render in whole pixels still presented a new frame every refresh.
- Core only runs deferred updates while nothing is scrolling. Believing
  nothing was, it ran blocking work in the middle of these scrolls.

The default is non-crisp today: scroll_speed 50.0 with scroll_delay 0.01 is
50 px/s, which on a 100Hz panel is half a pixel per refresh. That cannot
render as motion -- it alternates 0px and 1px steps and judders at a 50Hz
beat, on every scoreboard, out of the box. Resolved through the ladder it
stays 50 px/s and holds each frame for two refreshes: same speed, whole-pixel
motion.

The stepping disagreement that used to justify a separate module is gone.
scroll_config avoided frame-based mode because it stepped on a wall clock at
1/scroll_delay with scroll_delay set to the frame period, so the decision sat
on its own threshold and flipped on sub-millisecond jitter. That branch now
accumulates elapsed time, identical arithmetic to the time-based one, so the
two differ only in the units the speed arrives in.

What is NOT shared, and must not be: the two modules read identically-named
keys with different meanings. Here scroll_speed is px/SECOND and scroll_delay
only converts to px/frame; in scroll_config scroll_speed is px per STEP, so
px/s is speed/delay. Passing this module's settings dict to the resolver turns
50 px/s into 5000, clamped to 500 -- a tenfold speed-up everywhere. So
_get_scroll_settings keeps sole ownership of reading sports config, including
the league merging, and hands the resolver a plain px/s. A test pins that
specific number, because it is the mistake the refactor invites.

MIN/MAX_PIXELS_PER_FRAME are gone; the resolver bounds speed and the helper
clamps FPS. _resolve_target_fps stays, re-purposed: under the old model that
key was the rate frames were presented at, so it is the faithful translation
into the refresh the ladder is computed against, used when no hardware
refresh is configured.

Speed changes for panels that are not 100Hz: 50 px/s becomes 60 at 60Hz
(+20%) and 48 at 120Hz (-4%). At 100Hz it is unchanged.

* fix(display): drop the frame hold when a scroll times out, not just when it says so

set_scrolling_state(False) clears the hold. The other way a scroll ends is
is_currently_scrolling() deciding, after scroll_inactivity_threshold of
silence, that it is over -- which is what happens when the rotation moves on
mid-scroll or a plugin is torn down. That path cleared the flag and kept the
hold, so every later plugin, scrolling or static, was presented at refresh/N
by whoever scrolled last, until something called the explicit stop.

The method's own docstring already states the rule this breaks: the hold "must
not outlive the scroll that asked for it". The timeout was the exception it
did not cover.

Pre-existing, but reachable by three plugins before and eleven after the
sports scoreboards moved onto the shared resolver, so it belongs with that
change. The test ages the activity timestamp past the threshold rather than
sleeping.

Also adds scripts/sports_scroll_check.py. The sports scroll path is per-league
opt-in, so a rig showing static game cards never constructs a
SportsScrollDisplay and none of its pacing can be observed from a normal run
-- which is exactly what happened when this change was first put on hardware:
26 minutes, zero sports scroll lines. The script drives the path directly with
synthetic games and asserts the three things the resolver is meant to buy: the
speed lands on whole pixels, the hold is published, and it is released after.
It never starts or stops the display service, matching scroll_speeds.py, so a
crash here cannot leave the panel dark.

* fix(scripts): refuse to grab the panel while the display service has it

The module docstring already said to stop ledmatrix first. Nothing enforced
it, and running the script against a live service is not a harmless mistake:
rpi-rgb-led-matrix configures GPIO directions and the hardware PWM inside
RGBMatrix(), and when the root check fails it calls exit() from C with no
cleanup. The service keeps rendering and swapping onto pins that have been
reconfigured underneath it, so the panel goes black while every diagnostic
says the display is healthy -- fresh framebuffer, every pixel lit, "RGB Matrix
initialized successfully", nothing in the log. A restart fixes it, once you
work out that is what happened.

Found the hard way: this is what took the panel down on the test rig, not the
change the script was written to verify.

--fallback skips the check, since it never opens the matrix. --force is there
for anyone who means it.

* chore(scripts): annotate the subprocess call the way this repo already does

Codacy fails a PR on one new issue, and bandit B404 fires on any subprocess
import. scripts/run_plugin_tests.py carries the same suppression with the same
justification -- list-form argv, no shell -- so this follows it rather than
inventing a second convention.

ChuckandClaude Opus 5 4423ec33d5 feat(plugins): search, filter and sort for Installed Plugins, on a shared ListFilter helper (#540)
* feat(plugins): add search, filter and sort to Installed Plugins, on a shared helper

The Installed Plugins grid had no way to narrow it down: no search, no way to
see only what's enabled, disabled, or out of date. On a rig with a couple dozen
plugins that means scrolling the whole grid to find one.

The two sections below it already solved this, twice, independently — the
Plugin Store and Starlark Apps carried a copy-paste fork of the same ~600 lines
(filter state, apply-filters-and-sort, page renderer, pagination strip,
active-filter badge, listener wiring). Rather than add a third copy, this
extracts the shared machinery and builds the new toolbar on it.

New: web_interface/static/v3/js/plugins/list_filter.js — ListFilter.create()
owns debounced search, filter axes, sort, the active-filter count, Clear, and
optional pagination/persistence. Callers keep their own card markup via a
`render` callback. Three control types cover every axis the page uses: pills
(new), select (store category, starlark author) and cycle (the tri-state
All -> Installed -> Not Installed button).

Installed Plugins gets a compact toolbar: search box, one-click All / Enabled /
Disabled / Updates pills, and a sort dropdown (A-Z, Z-A, updates first,
recently updated, category). Filters reset on load, so you never come back to a
mysteriously short list. No new CSS — this is the first consumer of the
.filter-pill rules already sitting unused in app.css.

renderInstalledPlugins() is split so it still publishes canonical state while
renderInstalledCards() draws only the visible subset; the filtered list is
never assigned to window.installedPlugins, which the toggle handler,
isStorePluginInstalled(), runUpdateAllPlugins() and the Alpine config tabs all
read as their source of truth. Toggling a plugin while filtered pins its card
so it doesn't vanish from under the cursor.

The Store and Starlark migrations are behaviour-preserving: same element ids,
same localStorage keys (storeSort/storePerPage, starlarkSort/starlarkPerPage),
same tri-state button markup, same pagination. Verified by differential tests
that run the old and new implementations side by side against identical
fixtures and compare every observable after each interaction. The only visible
change is the pagination attribute (data-store-page/data-starlark-page ->
data-list-page), which nothing outside its own click handler referenced.

Net -156 lines in plugins_manager.js while adding a feature.

* fix(plugins): keep raw search text, and stop the store search refetching

Two review findings from CodeRabbit on #540.

Do not write the trimmed search value back into the input. setSearch() trimmed
before storing, and syncControls() then copied that trimmed value back over what
the user had typed. Pausing longer than the debounce after typing a space
deleted the space (and reset the caret), making multi-word terms effectively
untypable. The raw text is now kept alongside the trimmed one: filtering and
activeCount() still use the trimmed value, while the input keeps exactly what
was typed.

Remove the legacy #plugin-search / #plugin-category listeners in
initializePlugins(). They bound searchPluginStore as the event handler, so the
DOM event arrived as its `fetchCommitInfo` argument — always truthy, which
skipped the cached-filter fast path and refetched /api/v3/plugins/store/list
with commit info on every keystroke burst and category change. The store's
ListFilter controller already filters the cached list, which is what those two
controls should do. This double-binding predates this PR (the old code guarded
with _listenerSetup and _storeFilterInit, two different flags, so both sets
stayed live); it is fixed here because the refactor owns that wiring now.

Both fixes are covered by tests that fail without them: the trailing-space
regressions in the installed-plugins DOM suite, and a new whole-file jsdom test
that counts fetches while typing (1 request at init, 0 thereafter; previously
1 -> 2 -> 3 -> 5).

* fix(plugins): build pagination via DOM APIs, drop computed member access

Addresses the five Codacy security findings, all in list_filter.js.

Pagination no longer assembles an HTML string (3 findings: 2 critical + 1 high,
"unsafe assignment to innerHTML"). The interpolated values were only page
integers and local class constants, so there was no injection path, but
concatenating markup into innerHTML is the pattern the scanners flag and
createElement is no less clear. Each button now also owns its click listener
directly instead of the container being re-queried afterwards, and the strip is
cleared with textContent = '' rather than by assigning empty markup. No
innerHTML assignment remains in the file.

haystack() now walks Object.entries(item) and keeps the configured fields,
instead of reading item[field] per field ("generic object injection sink").
Field order no longer drives the haystack order, which is irrelevant to the
substring test. matches() iterates controls with for...of instead of an index
("variable assigned to object injection sink").

The rendered pagination is unchanged: same buttons, labels, page numbers,
disabled states and classes. The old-vs-new differential tests now compare
pagination structurally (tag, text, page, disabled, sorted class list) rather
than as an HTML string, since building nodes legitimately serialises
differently — «/» as characters rather than &laquo;/&raquo;, disabled="" rather
than a bare attribute. That comparison is stronger than the string one it
replaces, and the real-DOM suite still drives the actual page buttons.

* fix(plugins): keep configured field order when building the search haystack

The previous commit swapped item[field] for Object.entries(item) to clear a
static-analysis object-injection warning, and in doing so changed the order of
the haystack: entries follow the object's own key insertion order, not the
configured `fields` order. Since the values are concatenated, that order decides
which values end up adjacent, so a multi-word query spanning a field boundary
matched differently. For store fields [name, description, author, id, ...] and
API objects keyed {id, name, description, author, ...}, "bob plugin-01" matched
before and stopped matching after.

That contradicted the behaviour-preservation claim for the store and starlark
migrations, and the differential tests missed it because every fixture query was
a single word.

Values now come out of a Map built from Object.entries, iterated in `fields`
order: the original haystack is restored, and there is still no computed member
access for the analyser to flag.

Regression coverage for the ordering itself, at both levels:
  - unit: phrases spanning name->id and category->tags, plus the reverse
    (object-key) order asserted NOT to match
  - differential: the same class of query compared old-vs-new, with a guard that
    the phrase actually matches something so a mutual zero-result cannot pass
    vacuously

Verified both fail without this fix (3 unit, 2 differential) and pass with it.

* test(web): add JS suites for ListFilter and the plugin-manager grids

No JS toolchain exists in this repo, so these are plain node scripts with no
framework: each prints ok/FAIL lines and exits non-zero. `node test/js/run_all.js`
runs everything, skipping the DOM suites (rather than failing) when jsdom is
absent or nothing is listening, so it stays useful in a bare checkout.

  unit/test_list_filter.js    ListFilter search/filter/sort/count/sticky, driven
                              through the installed-plugins config eval'd
                              verbatim out of plugins_manager.js so the test
                              cannot drift from the real configuration
  unit/test_render_cards.js   renderInstalledCards markup, both empty states,
                              and escaping of hostile plugin metadata
  dom/test_installed_dom.js   the toolbar in a real DOM, including the HTMX
                              partial re-swap and a getComputedStyle check that
                              .filter-pill[data-active] matches what we emit
  dom/test_store_dom.js       store pagination, per-page, category, tri-state
                              Installed button, persistence across a re-boot
  dom/test_no_double_fetch.js loads the whole plugins_manager.js and counts
                              requests, so a keystroke cannot refetch the store

The DOM suites deliberately fetch the partial and the plugin data from a running
web interface instead of using fixtures, so a renamed element id or a changed
payload shape fails them loudly. Point them at a rig with a full plugin set when
it matters (BASE=http://host:5000); a dev box with two plugins installed passes
while exercising very little.

Several assertions exist to stop specific bugs recurring: trailing spaces
surviving the search debounce, a query spanning two adjacent search fields
(haystack field order is load-bearing), and window.installedPlugins staying at
full length while the grid is filtered. Others guard against passing vacuously —
counting only non-skeleton cards, and checking a search phrase matches something
before comparing two result sets.

The old-vs-new differential suites that verified the store and starlark
migrations are not included: they compared against the pre-refactor code, which
now exists only in git history.

ChuckandClaude Opus 5 26769ee37f fix(starlark): the store authenticated with a key nothing writes (#541)
#535 restored the thirteen routes, so the store stopped answering 404 --
and still would not load. Confirmed against a running device before
anything was changed: /repository/browse answers 200 with 1000 apps in
27s, so the routes are fine. Two things underneath them are not.

**The store never used the token the user configured.** The three
repository routes read `github_token` off config.json. Nothing writes
that key -- it is not in config.template.json, no setting offers it, and
it appears nowhere else in the codebase. The configured token goes to
config_secrets.json as `github.api_token`, which PluginStoreManager
loads and every other GitHub caller uses. So the store could never be
authenticated: 60 requests/hour, on the same per-IP budget 48 installed
plugins spend on update checks, while the 5000 the user had already
configured sat unused. On the device, /plugins/store/github-status
reported authenticated with a limit of 5000 at the same moment
/starlark/repository/browse reported 60, with 18 left. The store going
blank was that 60 running out.

**Every failure looked identical.** list_all_apps_cached turned any
listing failure -- rate limit, DNS, timeout, non-200 -- into an empty
app list, and the route sent that out as `status: success`, so a rate
limit and an empty repository drew the same blank grid with no error
anywhere. It now returns the reason, the route answers 502 with it, and
a failure is no longer cached as an empty repository for two hours.

The guard for a bad response was itself a crash: _make_request catches
`(json.JSONDecodeError, ValueError)` but `json` was never imported, so
evaluating the tuple raises NameError and the guard written for exactly
this case never ran. Reachable whenever something on the path answers
with HTML -- a captive portal, a proxy page, a DNS-hijacking router.

Seventeen handlers answered 5xx with no detail at all.
test_no_api_v3_handler_discards_its_exception is meant to prevent that
across api_v3, but it matched one exact message string, and all thirteen
Starlark routes wrote their own wording. The guard now keys on the shape
that matters: if it returns 5xx, it says why. The 15 pre-existing
non-Starlark functions are listed as a set that may shrink, never grow.

**The listing was capped at 1000 and did not say so.** The contents API
truncates a directory silently; tronbyt/apps has 1075 app directories,
so the store showed a truncated repository and looked complete doing it.
Now listed via the git trees API, which reports `truncated`, with the
contents API kept as a fallback.

Not addressed: the 27-second cold load -- 1075 manifests fetched five at
a time behind skeleton placeholders -- which is probably the largest part
of what "does not load" feels like, and wants its own change.

25 new tests.

ChuckandClaude Opus 5 968b953a51 fix(display): pin one text layout engine, and give the 5x7 BDF face a size (#539)
* fix(display): pin one text layout engine, and give the 5x7 face a size

Two ways a font could render differently on two machines running the same
code, both found while diagnosing four plugins whose golden images passed on
the machine that generated them and failed everywhere else.

**Layout engine.** `ImageFont.truetype` picks its engine at load time: Raqm
where the host Pillow was built with libraqm, Basic otherwise. The two round
fractional glyph advances differently. `PressStart2P-Regular.ttf` at 8px has
whole-pixel advances, so they agree — which is why most of the fleet matched
everywhere and hid this. `4x6-font.ttf` at 6px does not: glyph positions drift
cumulatively along a run, and the four plugins that draw body text in it
(geochron, of-the-day, christmas-countdown, ledmatrix-weather's almanac) are
exactly the four whose goldens travelled badly.

Every core font load now goes through `src/common/font_layout.load_truetype`,
which pins the Basic engine, so a render depends on the font file and the size
and nothing else. Basic gives up complex-script shaping and kerning pairs;
neither applies to bitmap-grid faces on an LED panel. Output is unchanged on a
host without libraqm.

**Zero font height.** `DisplayManager` built the 5x7 BDF face with
`freetype.Face(path)` and never called `set_char_size`, so `face.size.height`
stayed 0 and `get_font_height()` returned 0 for it — callers stacking rows by
`prev_y + prev_height + gap` drew two lines on top of each other. The
start-up line `Calendar font size: 0 pixels` has been printing the symptom all
along. `font_manager._load_bdf_font` already called `set_char_size`, so
whether measurement worked depended on which path loaded the face.

`DisplayManager` now sets it too, and `get_font_height()` falls back to the
strike the file declares rather than returning a zero line height.

* fix(display): give the startup banner a rung that fits a full address at 64px

CI caught what pinning the layout engine exposed rather than caused.
`_fitting_font` walks PressStart2P then 4x6 at 6px, and "255.255.255.255" --
the widest thing the startup banner ever shows -- measures 66px at 4x6/6px
against the 62 a 64x32 panel has to give. It used to squeak in only because
the measurement depended on which layout engine the host Pillow happened to
have; with the engine pinned it does not, so the rung the worst case actually
needs is now in the ladder instead of implied: 4x6 at 5px, which measures 51.

The fallback was wrong in the same place. When nothing in the ladder fit, it
returned `self.font` -- the *widest* option, and precisely how "Initializing"
came to run off the side of a 64px panel to begin with. It returns the
narrowest face that loaded now.

test/test_initializing_screen.py: 34 passed.

* fix(display): name the exceptions the BDF strike read can raise

Codacy flagged the try/except/pass. It was already narrow in intent -- a
malformed strike table on the measurement path must degrade to "size unknown"
rather than take the display down -- but a bare `except Exception: pass` says
neither of those things and hides a genuinely broken font behind a silent 8px
fallback. It now catches what reading `available_sizes` can actually raise and
logs which face failed.

These are fetched at runtime by the logo cache; they are not source, and they

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

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

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

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

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

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

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

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

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

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

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

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

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

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

All in the new bridge, all real:

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

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

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

* fix: the review findings on this PR

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

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

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

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

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

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

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

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

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

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

ChuckandClaude Opus 5 793b988d33 fix(starlark): toggle the app id the list published, and store a relocatable star_file (#537)
The two review nitpicks left over from #535. Both are still on main after
that merge; the five findings alongside them landed with it.

**The toggle could not find what the list had just shown.**
`_starlark_virtual_plugins` publishes the raw manifest key as
`starlark:<key>`, and `_toggle_starlark_app` passed it back through
`_validate_and_sanitize_app_id`, which lowercases and rewrites every
character outside `[a-z0-9_]`. An app stored as `My-App` was listed as
`starlark:My-App` and looked up as `my_app`, so toggling an app the page
had drawn a moment earlier answered 404. Keys written by
`_install_star_file` are already sanitised, so this only shows up for
manifests written by the starlark-apps plugin itself or edited by hand.

`_validate_starlark_app_path` rejects traversal without rewriting, so it
is the check to use here -- listing and toggling now agree on one key.
The updater also uses `setdefault` rather than indexing: the app is
loaded but its on-disk entry need not exist, and `_update_manifest_safe`
does not catch `KeyError`, so that escaped as a 500 rather than writing
the entry.

**`star_file` was stored absolute.** Readers join it to the app's own
directory -- `_standalone_render_starlark_app` does `app_dir /
app_data.get('star_file', f'{app_id}.star')` -- so the key's default is a
bare filename and an absolute value gave it a second meaning. Since
`Path.__truediv__` discards the left side when the right is absolute,
the manifest was pinned to whatever PROJECT_ROOT installed it, and a
moved or redeployed install could not find its own file. Storing
`dest.name` matches the default and stays relocatable. Read paths are
unchanged, so manifests already holding an absolute path keep working.

Chuck 50258635a8 fix(starlark): restore the API routes #330 dropped (#535)
The Pixlet install button reported "Pixlet install failed: Resource not found" -- Flask's 404 handler, because the route did not exist. #253 added thirteen Starlark routes; #330 rewrote api_v3.py and dropped all of them, along with the `starlark:<app_id>` entries that surface installed apps in the plugins list and the toggle branch that enables them.

Restores all thirteen routes, the plugin-list entries and the toggle path, so Pixlet installs, the app store browses and installs, and an installed app can be managed like any other plugin.

Not a straight revert. Three error paths stopped returning exception text to the caller; the manifest write moved off a shared temp filename that two concurrent writers could interleave; both dynamic importers stopped leaving half-initialised modules in sys.modules; the config update rolls back when the save fails; the toggle checks that persistence succeeded; and the path check returns the validated path instead of a boolean so callers stop re-joining the raw value. New tests no longer reach GitHub.

Verified on a 256x64 Pi: Pixlet installs and runs (v0.53.1), the store lists 1000 apps, install/toggle/uninstall round-trip, and traversal and command-injection probes are rejected at every entry.

25 CodeQL alerts dismissed as verified false positives -- path-injection where traversal is blocked, and one list-form subprocess with no shell. Both classes already present on main.

Full core suite: 3981 passed.

ChuckandClaude Opus 5 c9289e3a1d fix(store): update_plugin silently did nothing for four installed plugins (#536)
install_plugin() deliberately renames a plugin's directory to the MANIFEST id
when it differs from the REGISTRY id, so registry `stocks` lands in
`ledmatrix-stocks/`. Every lookup in _find_plugin_path() is by directory name,
so update_plugin("stocks") found nothing, logged "Plugin not installed", and
returned False.

Nothing surfaced that to the user. Clicking update in the web UI was a no-op
with no error, and the plugin stayed on a stale version indefinitely. Four
installed plugins hit this on a real device -- leaderboard, music, stocks and
weather -- found because a scripted update of eleven plugins failed on exactly
those four.

Adds a manifest-id scan as the LAST step of the resolution chain, so the two
documented lookups above it (configured dir, then the sibling plugins/
fallback) keep their exact meaning and ordering. That ordering is pinned by
test_discovery_path_contract.py, which characterises the divergence between
the three resolvers on purpose; this extends the chain rather than reordering
it. Directories renamed aside with '.standalone-backup-' during an install or
rollback are skipped, since matching one would report a half-finished install
as a live plugin.

Also adds scripts/audit_render_path.py, which walks the call graph from
display() and reports blocking calls reachable from it. display() runs on the
render thread, so anything slow there stalls the panel; on a vsync-paced loop
a single 15ms call drops a frame and a network round trip freezes the marquee.
Two instances were already found the slow way, by reading frame-time
histograms -- odds-ticker reading the scoreboard cache per frame, and
soccer-scoreboard timing out inside update(). The audit finds that shape in
the source instead. It is a heuristic and says so: a hit behind an interval
check may be fine.

It currently flags 23 calls across six plugins. The clearest is
ledmatrix-music, whose display() falls back to an inline
requests.get(timeout=5) when album art has not been prefetched -- a deliberate
"show the art rather than go blank" tradeoff by its author, but up to five
seconds of frozen panel. Reported, not changed; that is its owner's call.

185 store tests pass. Three of the six new tests fail without the fix.

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

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

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

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

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

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

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

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

Measured after: 100 fps locked, no stalls observed, render thread down from
51% to 19% of one core.

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

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

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

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

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

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

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

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

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

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

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

On the hardware this now reads:

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

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

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

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

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

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

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

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

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

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

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

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

183 tests pass on the Pi.

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

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

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

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

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

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

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

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

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

test_another_plugin_stopping_does_not_strand_a_hold pins the interaction that
broke this.

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

Eight findings, all reproduced before fixing.

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

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

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

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

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

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

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

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

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

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

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

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

Full suite: 3889 passed.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Closes #533.

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

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

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

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

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

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

Closes #532.

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

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

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

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

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

Measured on the rig:

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

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

Closes #527.

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

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

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

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

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

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

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

Closes #531.

* refactor: narrow the exception handlers this branch introduced

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

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

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

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

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

CodeRabbit raised six; all six were real.

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

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

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

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

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

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

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

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

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

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

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

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

Codacy: 0 new issues, up to standards.

* chore: leave visual_display_manager untouched so #523 can merge

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

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

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

696acdbc7b feat(render_plugin): add --display-mode so multi-mode plugins can be rendered (#522)
* feat(render_plugin): add --display-mode so multi-mode plugins can be rendered

render_plugin.py always called plugin.display(force_clear=True) with no mode.
A plugin that declares one display mode is fine, but the sports scoreboards
declare three or more and keep their per-mode state on sub-managers; their
no-argument path selects nothing and returns False, so the render came out
blank with nothing to say why. Measured on nrl-scoreboard with identical
seeded state:

  live.display() directly                 True,  1892 lit pixels
  plugin.display(display_mode="nrl_live") True,  1892 lit pixels
  plugin.display()                        False,    0 lit pixels

--display-mode passes the requested mode through. It is only passed when
asked for, so the many plugins whose display() takes no display_mode keep
working untouched, and a plugin that declares modes but does not accept the
argument degrades to its default screen with a warning rather than a
TypeError.

This is what lets the plugin READMEs show a scoreboard at all, and it also
unblocks screens like birdnet_stats and the weather plugin's hourly, daily and
almanac modes, which could previously only be described in prose.

ChuckandClaude Opus 5 91d15a8943 fix(display): draw text 1-bit, so glyphs stay crisp on the LED grid (#521)
An LED panel has no partial brightness. PIL defaults ImageDraw's fontmode to
"L", which anti-aliases TrueType glyphs into a grey fringe the panel can only
round off -- a 4px glyph arrives smeared into 3px.

DisplayManager creates its shared `draw` in six places and set fontmode at
none of them, while _load_fonts loads extra_small_font as 4x6-font.ttf at
size 6. Measured at draw time, that face at that size puts 74% of its lit
pixels at partial coverage. Every plugin drawing small text through the
shared draw inherited the blur; geochron was the case that surfaced it.

The harness's VisualDisplayManager had the same gap, which mattered more than
it looks: goldens were recording anti-aliased text that production would not
produce, so the harness could not have caught this. Fixing only production
left geochron still blurry under the harness -- that is how the second site
was found.

Both are set to "1" so the harness renders what the panel renders.

Chuck 6bea1a7c21 fix(sports): say when the schema cannot be read, instead of failing silently (#520)
_schema_font_size swallowed every exception and cached an empty dict. That is
not cosmetic. With no schema, a configured font size can no longer be compared
against the schema default, so every size is treated as a deliberate user
choice and skips the snap to the font's pixel grid -- which renders
4x6-font.ttf at 6 instead of 7: a 3px-wide glyph instead of 4px.

That shipped. On a 256x64 panel it made the odds, the team records and the date
row hard to read, and it was found by a user counting pixels on a photo of the
panel rather than by anything here. The cause (_plugin_dir returning None under
the real plugin loader) is fixed in #519; this makes the same class of failure
audible next time:

    Orphan: could not read config_schema.json (FileNotFoundError: ...); every
    font size will be treated as user-chosen and will skip its pixel grid
    snap. Font sizes may render a pixel narrow.

The message names the consequence, not just the error, because the error alone
does not suggest "your fonts are a pixel narrow".

Logged rather than raised: an unreadable schema must not stop a plugin
rendering. The cache is built once per class (per schema path in sports_card),
so this cannot repeat per frame.

Scope deliberately small. An audit of the three shared modules found 23 handlers
that swallow and return a default, but all 23 catch specific types -- TypeError,
ValueError, ImportError -- turning bad config values into defaults, which is
what they are for. Of 77 broad handlers across the font and odds paths, 74
already log. Only these two were both broad and silent.

Chuck 0730d95200 fix(sports): let the plugin declare its own directory, don't deduce it (#519)
_plugin_dir() returned None on every device. The consequence was silent and
reached the panel:

    _plugin_dir()       -> None
    _schema_font_size() -> None for every element
    -> a configured size equal to the schema default stops looking like a
       default and is treated as a deliberate user choice
    -> the snap to the font's pixel grid is skipped
    -> 4x6-font.ttf renders at 6 instead of 7: 3px-wide glyphs, not 4px

On a 256x64 panel that made the odds, the team records and the date row hard to
read. Both `odds` and `detail` were affected -- anything resolving a
grid-snapped schema default was a pixel narrow.

Why it was invisible here. PluginLoader._namespace_plugin_modules renames every
bare module a plugin brought in (sports, game_renderer, ...) to
"_plg_<plugin_id>_<module>" and REMOVES the bare sys.modules entry, so two
plugins owning a module of the same name cannot collide. A class defined in
sports.py still reports __module__ == "sports", but sys.modules["sports"] is
gone, so walking the MRO for a module with a __file__ finds nothing.

Every test here imported plugins directly, which leaves the bare entry in
place, so the walk succeeded. The safety harness loads plugins its own way and
never reproduced it either. It was found by a user counting pixels on the
panel.

The directory is now declared by the plugin (_PLUGIN_DIR) and only deduced as
a fallback, for hosts that declare nothing -- the plugins' own probe harnesses
build classes with type().

Verified on hardware, which is the only place the original failure appeared:
before, the live service logged plugin_dir=None and 4x6-font.ttf@6 for all six
football managers; after, plugin_dir resolves and both odds and detail are @7.

Five regression tests, including the production shape: a class whose __module__
is absent from sys.modules still resolves via its declared directory, and the
precondition that the MRO walk alone returns None is pinned so the test keeps
meaning something if the fallback changes.

Chuck 32d637a446 fix(store): read the core version from disk, not from a stale import (#518)
* fix(store): read the core version from disk, not from a stale import

Updating the core to 3.3.0 and then updating plugins refused all eight sports
scoreboards:

    Refusing to install nrl-scoreboard: NRL Scoreboard supports LEDMatrix
    >=3.3.0, but this system is running 3.2.0.

while src/__init__.py on that machine read 3.3.0. Observed on hardware, not
theorised.

The gate ran `from src import __version__ as core_version`, which binds
whatever the process loaded at start. The plugin store's gate lives in the web
UI, a long-lived service of its own, and the update route deliberately restarts
nothing -- it replaces files on disk and asks the user to restart. Its prompt
named only the *display* service, so a user who followed it left the web
process holding the previous number.

Stale by exactly one release is the case that bites: every plugin flooring on
the release you just installed is refused, blaming a core version that is
already correct on disk. It reads as a broken plugin store. 3.3.0 is the first
release where this hits a whole family at once, since all eight scoreboards
floor there.

compatibility.current_core_version() reads the version from the file instead,
falling back to the imported value on any failure -- so it can only ever be as
correct as before, never worse. All four gate call sites use it: three in
store_manager (install, the git-pull update path, install_from_url) and one in
plugin_loader's advisory warning.

The restart prompt now names both services.

Twelve tests, including the hardware failure itself: a process holding 3.2.0
while disk says 3.3.0 refuses hockey, and reading fresh allows it. The inverse
is asserted too -- a genuinely old core still refuses, so the gate has not
become permissive. One test greps both modules for the old import-bound read;
reintroducing that line fails it, which is what stops this coming back.

Not changed: web_interface/__init__.py also imports __version__, but for
display rather than gating, and the API endpoint already reports a fresh
git describe.

* fix: drop the unused os import

Left over from a first draft that joined paths by hand before this used
pathlib. Flagged by CodeRabbit on #518; confirmed dead -- no os. reference
remains in the module.

ChuckandClaude Opus 5 bc2dbf3824 feat(sports): share the sports.py surface that is identical in all eight scoreboards (#515)
* feat(sports): share the sports.py surface that is identical in all eight

Nine scoreboards ship their own sports.py -- 41,326 lines. Comparing executable
ASTs across the eight that share a lineage, 48 method bodies are byte-identical
in every one: 1,007 lines carried eight times, so 8,056 lines that must be
edited eight times to fix once.

They are the parts with no sport in them: the selection and rotation engine
(_round_robin_favorites, _favorites_first, _compose_selection,
_check_ranking_coverage, _game_divisions, _normalise_quality), the font/colour/
date subsystem (_scale_headline_fonts, _scorebug_font, _resolve_font_size,
_format_game_date, _font_color), and the switch-mode upcoming card
(_draw_upcoming_center_switch). Nothing here knows what an inning is.

Mixins rather than free functions: every one of these reads host state, so
rewriting 48 bodies into free functions would be a rewrite rather than a move,
and it is the move that keeps the renders identical.

Three of the 48 are deliberately left in the plugins, because a byte-identical
body is not automatically safe to move:

- _get_timezone calls resolve_timezone, imported from a per-plugin module
  (hockey_timezone, soccer_timezone, ...). All eight of those differ -- each
  carries its own _WRITEBACK_FIXED_IN -- so hoisting the caller would silently
  bind every scoreboard to one plugin's copy.
- _extract_game_details and _fetch_data are @abstractmethod stubs. They are the
  sport contract; satisfying them from a mixin would let a plugin instantiate
  without implementing its own sport.

_resolve_font_path went the other way: a module-level function, identical in all
eight, that _scale_headline_fonts needs -- so it is inlined here.

_schema_font_size needed a real change rather than a move. It located the
plugin's config_schema.json with __file__, which here is src/common/, so the
load failed silently, the cache stayed empty and every element fell back to an
unsnapped size -- measured at 81% anti-aliased edges on a panel that should be
pixel-crisp. It now recovers the plugin directory from the instance. Note that
type(self).__module__ alone is not enough: SportsCore is an ABC, so a subclass
built with type(name, bases, ns) -- which the plugins' own tests do -- reports
its module as "abc". _plugin_dir walks the MRO past those synthetic classes to
the first module sitting beside a config_schema.json.

Worth recording: the 176 harness renders did NOT catch that regression. The
plugin's own test_fonts_are_crisp.py did. Renders alone were not a sufficient
gate here.

Not merged with src/common/sports_card.py despite fourteen same-named twins.
Only five are provably equivalent by source comparison; the other nine differ in
ways inspection cannot settle, and a wrong guess silently changes what every
scoreboard draws. That merge needs differential testing and is its own change.

* fix(sports): declare the constants the mixins read, and test the contract

CodeRabbit found _QUALITY_CHOICES and _RANKING_COVERAGE_SECONDS read by
_normalise_quality and _check_ranking_coverage but never defined on a mixin.
Confirmed: both are declared by all eight scoreboards, so nothing fails today --
it would only have bitten the ninth plugin to adopt this, at runtime, mid-render.
Both are identical everywhere, so they get defaults here; each plugin's own copy
still shadows them.

Auditing for others showed those two were the only ones, but also that the
host-contract docstring was substantially incomplete: it listed 21 attributes
where the mixins actually read about 40, and omitted five hooks
(_is_favorite_game, _is_game_really_over, _is_ranked_game,
_passes_other_filters, _get_timezone). The section is now derived from that
audit rather than remembered.

test_sports_shared.py covers what is genuinely new, not the moved bodies:

- The contract itself. It parses the module for every ALL-CAPS `self.X` the
  mixins read and asserts each is defined, so the next omission fails here
  rather than in the field.
- _plugin_dir, the only new logic in the move. Including the case that made it
  necessary: SportsCore is an ABC, so a subclass built with type(name, bases,
  ns) -- which the plugins' own tests build -- reports __module__ as "abc". The
  test asserts that precondition before asserting the walk steps past it.
- The three SportsLive bodies. Hockey and lacrosse disable live mode in their
  harness fixtures, so the 176 renders never reach this path; testing the mixin
  directly means coverage no longer depends on which plugin happens to have a
  unit test.

Two of those tests pin things that would otherwise be silently undone.
SportsRecentSharedMixin does carry an __init__ -- SportsRecent.__init__ was one
of the 48 byte-identical bodies. Its bare super() binds to where it is defined,
now the mixin, so it only reaches the host because the mixin is listed first in
the bases. One test proves the chain runs; the next proves that reversing the
order silently skips the host constructor.

* fix(sports): drop three unused imports and let the matcher narrow

Codacy flagged five issues on this file.

Three are unused imports: math, abc.abstractmethod and zoneinfo.ZoneInfo.
Nothing in the module references any of them -- the timezone work goes through
pytz, and the @abstractmethod mention in the module docstring describes the
two stubs that deliberately stayed behind in each plugin, not anything
declared here. pyflakes agrees; all three are removed.

The other two are "team_in is not callable" on the round-robin favourite
matcher. That call is already guarded by callable(), so it cannot raise at
runtime, but callable() is not a narrowing construct a static analyser
follows: the name still carries the None from getattr's default. Normalising a
non-callable to None and branching on `is None` gives the analyser a test it
does understand, and keeps the guard.

Behaviour is unchanged. _round_robin_favorites has no test coverage, so I
exercised it directly on both paths -- a host with _team_in (id matching, the
NRL case) and one without (abbreviation matching) -- across limits 1 to 4, and
the selections are identical before and after. A host whose _team_in is
present but not callable still falls back to abbreviation matching rather than
raising.

test/test_sports_shared.py: 27 passed. The 9 collection errors under
`pytest test/ -k sport` reproduce identically on the unmodified branch and are
not from this change.

2026-09-03 13:29:37 -04:00
Chuck cb0545ecb3 release: report 3.3.0, so the version the gate reads matches the tag (#516)
v3.3.0 is tagged, but src/__init__.py still says "3.2.0" -- and that string,
not the git tag, is what the compatibility gate compares
(store_manager.py: `from src import __version__ as core_version`).

The effect is that every plugin flooring at 3.3.0 is refused on a device
running 3.3.0. Checked against the real gate and the real manifest:

    core __version__ reported to the gate : 3.2.0
    hockey floor                          : 3.3.0
    verdict                               : REFUSE
      "supports LEDMatrix >=3.3.0, but this system is running 3.2.0"

That is all eight sports scoreboards plus calendar 1.2.3, and it would read as
a broken plugin store rather than a stale constant.

The TRUSTWORTHY_FLOOR escape hatch does not cover this: it exempts cores
reporting below 2.0.0 as "unknown rather than old", and 3.2.0 is above it, so
the number is trusted and compared.

This is the same slip as v3.1.0, which was tagged six weeks before its version
string was bumped and shipped __version__ = "1.0.0" -- the reason that escape
hatch exists at all.

With the bump, the same gate call returns ALLOW for hockey at both the
sports_card and sports_shared floors, and for calendar 1.2.3.

CHANGELOG.md gains the 3.3.0 section. That file is what plugin authors read to
decide which release to floor on, so it records the three new modules --
src/common/sports_card.py, sports_game_renderer.py and sports_shared.py --
against this version, along with the three traps in adopting the mixins.

No test pinned the old literal; the ones that care monkeypatch __version__.
135 compatibility tests pass.

Chuck 300cdaa250 feat(sports): share the scroll-card geometry the scoreboards all duplicate (#514)
* feat(sports): share the scroll-card geometry the scoreboards all duplicate

The card helpers moved to src/common/sports_card.py, which shared the eight
scoreboards' settings lookups. Their *geometry* stayed duplicated: nine
methods deciding how wide the centre strip is, how much room each logo gets,
and where an upcoming card's date and time land. Five were byte-identical in
all eight plugins; the other four were identical in seven, each with a
different single outlier.

That shape is why this is a mixin and not free functions. Comparing executable
ASTs against the eight plugins, 67 of the 70 method bodies are inherited
unchanged and 3 become ordinary overrides -- baseball keeps its own
_logo_slot_width and _draw_upcoming_game_status, hockey its own
_upcoming_date_and_time. No per-sport branching goes inside the base.

It deliberately has no __init__ and no state. The plugins' constructors differ
six ways and none of it is worth unifying, so adoption is one line on the
class statement plus deleting what now comes from here.

Placed in src/common/ rather than src/base_classes/sports/ on purpose:
importing that package pulls core.py -> DisplayManager -> rgbmatrix, and this
is pure geometry that must not drag a hardware import into every plugin that
uses it. It sits next to sports_card.py, which the same plugins already use.

Only _SCORE_PROBE varies between plugins, so leagues that reach three digits a
side override that one ClassVar; the four gap constants are identical
everywhere.

The tests drive the mixin through a host that provides exactly the surface the
module docstring names and nothing else, so the mixin growing a new self.*
dependency the plugins do not have fails the contract test rather than
shipping.

* fix(sports): reject non-finite card settings before they abort the render

A center_gap of inf passes `isinstance(x, (int, float)) and x >= 0` unharmed
and then raises OverflowError out of int(). The surrounding guards caught only
(TypeError, ValueError), so it escaped and took the whole card render with it.
The same holds for center_gap_ratio, the two clamp bounds, and layout offsets,
where "inf" arrives as a string and float() is happy to produce it.

Four of the five paths crashed; only a NaN ratio happened to survive, by
accident of min/max rather than by design.

This is pre-existing behaviour -- the bodies moved here verbatim from the eight
plugins and every one of them has it today. Fixing it in the mixin fixes it in
all eight at once, which is the argument for the mixin.

Guarded with math.isfinite() before any int()/round(), falling back to the same
defaults the finite paths already use, plus OverflowError added to the except
clauses as a backstop. Ordinary settings are untouched: all 192 scroll-card
renders (8 plugins x 8 panel sizes x 3 game types) stay byte-identical to
pristine main.

Found by CodeRabbit on #514 and confirmed by running it before fixing.
2026-09-02 16:22:25 -04:00
ChuckandClaude Opus 5 10da2f97fd feat(sports): share the card helpers the eight scoreboards each carried (#513)
Twenty methods were byte-identical in all eight scoreboards' game_renderer.py:
the colour pickers, the scroll_card settings lookup, the date and time
formatting, the favourite-team rules and the font-size grid snapping. Every fix
to any of it had to be made eight times, and a new scoreboard began by copying
them a ninth.

src/common/sports_card.py holds them once. 245 lines leave each plugin.

**Free functions, not a base class.** Every helper takes config/logger/fonts as
arguments rather than reading them off an instance, so a plugin keeps its
method and delegates the body -- call sites, signatures and override points are
all untouched. Adoption is therefore per-function and reversible, which is what
let all eight move with byte-identical renders.

The bodies are the plugins' code moved, not rewritten. Two deliberate
differences, both verified:

- crisp_size takes the seven-plugin guard (`not desired`) rather than
  football's. They agree on every real input; the extra guard only stops a
  None size raising TypeError, so adopting it is a no-op for seven plugins and
  removes a crash path for the eighth.
- schema_font_size caches per schema PATH. The plugins cached on their own
  class, which is the same distinction expressed without a class to hang it
  on; two plugins never share an entry. The path has to be passed in because
  the plugins derived it from __file__, and __file__ here is the core's.

Verified before any plugin was touched: 534 differential comparisons of the
helpers against afl's originals and 704 more of the font-sizing chain against
all eight plugins' originals -- 1,238 comparisons, zero differences. Writing
the constant tables by hand introduced two errors that check caught: the tie
colour was (255,255,0) instead of the plugins' (255,200,0), and a
"five_by_seven" alias that does not exist. Both are now taken from the plugins
verbatim.

43 tests pin the contract, including the cases the plugins' own comments record
as having bitten: a three-character string must not iterate into a colour, a
shared font face must give up rather than guess an element, a font_size equal
to the schema default carries no intent, and a bad timezone falls back to UTC
rather than blanking the card.

Full suite 3768 passed, 6 skipped.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

6e361e05cc docs(sports): record B6 as done, and what running it found (#435)
* docs(sports): record where B6 stands, and why it is waiting

The phase table had B4 as "next" and B5 as "after B4" while both had shipped,
and described B6 as blocked on B4's gate — which is now merged and released. A
plan that misreports which phase it is in is worse than no plan: the next
person reads it and repeats finished work.

Corrected, and three things that were only ever decided in conversation are now
written down:

  * **B6 is deliberately held.** 3.2.0 published 2026-08-03; 3.1.0 ran nine
    months before it. B6's premise is that cores without the module are gone,
    and there is no release-asset count or install telemetry to show that.
    Running it now strands users on their current plugin versions. The gate
    that makes it safe is already built and tested — it is the calendar that is
    missing, and no amount of further code changes that.
  * **Stop adopting further shared modules** (data_sources, game_renderer,
    base_odds_manager) until B6 closes. Each adoption adds a copy to keep in
    step against a payoff contingent on B6.
  * **A B5 retrospective**, because "the adoption went fine" is not what
    happened: four of eight shipped with scroll mode broken on a 3.2.0 core.
    The bundled fallback did not protect against it — the break was on the
    modern path — which is an argument for the sunset, not against it. Records
    the ledger too: net negative on disk until B6 runs.

Also replaces the "what's next" list, whose first five items were all done,
with what actually remains.

* docs(sports): stop a wrapped PR reference reading as a heading

A line wrapped onto "#433), the newest manifest entry ...", which
markdownlint reads as a malformed ATX heading (MD018). Reflowed so the
line starts with "(#431, #433)" instead.

Not the suggested fix: adding a space after the hash would have turned
the PR reference into "# 433". The B5 safety claim raised alongside this
was already corrected in ac44b5a.

* docs(sports): scope the B5 safety claim to the fallback

The heading read "B5 — adoption is safe by construction", which this same
document disproves two sections later: four of the eight adopted plugins
shipped with scroll mode broken on a 3.2.0 core and were repaired in
plugins #251.

The body was already careful -- it says fallback compatibility is what is
guaranteed, and that correctness on a core which *does* ship the module
needs object-level and scroll-mode validation. The heading was not, and a
heading is what a reader scanning the plan actually takes away.

Retitled to name both halves, with a sentence up front saying why the
unqualified claim is false and pointing at the retrospective that shows
it. The phase intro said "one of them is safe by construction and the
other is not"; that now says what it actually means -- one cannot break a
user on an old core, the other can.

The second review point, MD018 on the ATX heading at line 409, does not
reproduce: that line now begins "(#431, #433)" rather than "#433)", so
there is no bare-hash heading. `grep -cE '^#+[^ #]'` returns 0 for the
whole file.

* docs(sports): re-check the hold, and close two items that are already done

The remaining-work list had two entries that finished without the doc noticing,
which is the failure mode this file exists to prevent.

- The stale plugin-test tranche is gone. run_plugin_tests.py --all now reports
  174 passed, 2 skipped, 0 failed across the whole fleet. Recorded how to
  re-check it too: these are standalone scripts, not a pytest suite, and one
  calls sys.exit(1) at import, so pointing pytest at a plugin directory
  collapses into an INTERNALERROR that looks nothing like the real state.
- CLAUDE.md already says eight panel sizes.

That leaves the hardware soaks as the only open item needing work rather than
calendar time.

B6's prerequisite is now built -- core test/test_sports_sunset_matrix.py
(#505) -- so the phase table and the regression-test section say so, and the
two modelling traps it had to work through are recorded for whoever touches it
next: the copy-removed shape must be an unguarded import or the failure names
scroll_display_legacy instead of the core module, and only the leaf module may
be hidden because a pre-3.2.0 core still ships src/common/.

The hold itself is re-checked and unchanged: v3.2.0 is still latest,
__version__ is still 3.2.0, no 3.3.0, 23 days rather than the few months the
gate asks for. Also worth stating plainly -- the core updates by git pull, not
by downloading a release, so release-asset counts would not measure uptake even
if we had them. Whatever unblocks this has to come from the store side.

ChuckandClaude Opus 5 a686932c7e fix(store): land the install_from_url gate, which never reached main (#511)
#510 shows as merged, but into fix/gate-git-pull-updates -- #508's branch --
rather than main. #508 reached main first, so the sideload gate was left behind
on a branch. Same failure as plugins #350/#351, which merged into each other's
bases; worth knowing the pattern, because GitHub reports these as MERGED and
`gh pr list` shows nothing outstanding.

main today has two of the three routes gated: install_plugin (#431/#433) and
update_plugin's git branch (#508). install_from_url validates required manifest
fields and then installs whatever it found, never comparing the core version.

Cherry-picked unchanged from the orphaned branch -- it applies to main with no
conflict. TestSideloadGate pins the three cases the other routes pin: refuses a
floor above this core leaving nothing behind, still allows a compatible plugin
(the guard against a gate that refuses everything), and does not block a 2.0.0
floor on a core reporting an untrustworthy version.

Full suite 3725 passed, 6 skipped.

ChuckandClaude Opus 5 154525beb8 fix(background): release the payload after every callback, not after each one (#509)
Callers that join an in-flight fetch share one FetchResult. #499 released the
payload inside the delivery loop, so the first callback got the data and every
joiner got `result.data is None`.

That is not a quiet degradation. Consumers read `result.data.get('events')`, so
they raise AttributeError -- which the delivery loop catches and logs. The
entire failure surfaced as one line:

    ERROR - src.background_data_service - Error in callback for request
    nhl_2026_...: 'NoneType' object has no attribute 'get'

and a manager that silently never received its schedule. Seen on hardware:
NHLRecentManager logs "Background fetch completed for 2026: 1000 events" and
the very next line is the error, from NHLUpcomingManager's callback on the same
request -- which had already logged "No events found in shared data."

Deduplication is the normal case, not a corner. A sport's recent, upcoming and
live managers all want the same season schedule, so the second and third are
joiners on almost every cycle. _release_payload's own docstring said "once A
callback has been handed the data", singular, which is the assumption that
broke: the loop above it was written for many, and says so.

Moved after the loop, and guarded on `callbacks` being non-empty. The guard
matters: a request submitted without a callback must keep its payload, because
polling get_result() is then the only way to collect it. The per-delivery
release got that right by accident -- an empty list never entered the loop body
-- and the existing test for it caught the omission.

test_background_payload_release.py gains TestJoinersAllGetTheData: two
submitters on one in-flight cache_key, asserting both are handed a populated
payload, plus that the memory fix still happens once they have all had it.
test_background_fetch_dedupe.py already proved the joiner's callback FIRES; it
never checked what the callback received, which is the gap that let this
through.

Verified the new test bites: restoring the release inside the loop fails it
with "'second' was handed a released payload".

Full suite 3716 passed, 6 skipped.

ChuckandClaude Opus 5 9b522d412c fix(store): gate the git-pull update path (#508)
* fix(store): gate the git-pull update path

`install_plugin` gates every route that re-downloads, `_reinstall_with_rollback`
included. `update_plugin` has one branch that re-downloads nothing: a git
checkout pulls in place, installs dependencies, and returns True. A pull could
therefore deliver a manifest flooring above this core and nothing would notice
until the plugin failed to load — which surfaces as one line in the journal and
a display that silently stopped appearing.

Checked after the pull rather than before it, for the same reason
`_install_plugin_impl` checks after the download: the registry carries no
compatibility field, so the incoming floor is only knowable once the new commit
is on disk.

Undone with `git reset --hard` to the pre-pull commit rather than by removing
the directory. This is a live checkout, the old commit is still in the object
store, and the reset leaves the user on the exact version they were already
running — the same promise `_reinstall_with_rollback` makes, reached by the
means this path actually has, with no window where the plugin directory does
not exist. An unreadable manifest allows: it is not evidence of a floor.

Scope, stated plainly: monorepo plugins install as archives and update through
`_reinstall_with_rollback`, so they were already gated. Only registry entries
with no `plugin_path` reach this branch. It is closed anyway because the sunset
rule in the plugins repo's `08-shared-sports-code.md` names, as condition 3,
that the core enforces the floor "at install/update time" — and B6 rests on
that being true rather than merely written down. `install_from_url` is still
ungated; the tests say so rather than letting the next reader assume otherwise.

* fix(store): do not pull what the gate cannot un-pull

Review of the gate found a data-loss path it had introduced, plus two smaller
scope errors. All three from CodeRabbit on #508.

**The stash failure was load-bearing and was not treated as one.** update_plugin
stashes local changes before pulling; when that stash failed or timed out it
logged a warning and pulled anyway. That was harmless while nothing ever undid
a pull. It is not harmless now: the gate's rollback is `git reset --hard`, which
discards uncommitted tracked edits -- exactly the edits the stash existed to
protect. A pull does not refuse on a dirty tree as long as the incoming commit
touches other files, so the sequence completed silently: pull succeeds, gate
refuses, reset takes the user's work with it.

update_plugin now returns before pulling unless the tree was already clean or
was successfully stashed. Refusing costs an update in a case that had already
gone wrong; the alternative costs data. That also makes `--hard` safe by
construction in _gate_pulled_commit, and its comment now says so rather than
observing it in passing.

Pinned by test_a_failed_stash_stops_the_update_before_pulling, which writes a
local edit, forces the stash to fail, and asserts both that HEAD did not move
and that the edit is still on disk. Verified it bites: with the new guard
removed the file comes back as `class P: pass`, the edit gone.

**_HAS_GIT could take the module down instead of skipping it.** With no git on
PATH, subprocess.run raises FileNotFoundError, and this runs at import time --
before skipif can act, so the whole file errors rather than skipping. Now
catches OSError.

**The doc overclaimed the gate's reach.** It said the floor is enforced on
"every route that installs or updates" while the same passage notes
install_from_url is ungated. Both spots now scope the claim to registry-managed
installs and the two supported update paths, and name the sideload exception.

Full suite 3720 passed, 6 skipped.

Chuck cbc540a679 fix(assets): drop case-colliding duplicate league logos (#506)
Four league fallback logos were each tracked at two paths differing
only in case:

  assets/sports/mlb_logos/MLB.png  +  mlb.png
  assets/sports/nba_logos/NBA.png  +  nba.png
  assets/sports/nfl_logos/NFL.png  +  nfl.png
  assets/sports/nhl_logos/NHL.png  +  nhl.png

On Windows and default macOS the filesystem is case-insensitive, so
both index entries map to one physical file. Whichever git writes last
wins and the other entry reports as permanently modified, so `git
status` can never be clean and any `git pull` flips which one is dirty.

For MLB/NBA/NFL the two entries pointed at the same blob, so the
collision was only cosmetic. NHL was not: NHL.png is 1439x1621
(672455 B) and nhl.png is 768x768 (107184 B), so which resolution the
league fallback logo loaded depended on checkout order rather than on
the code.

Keep the uppercase path in each pair. Every logo lookup uppercases the
abbreviation before building a filename -- LogoDownloader
.normalize_abbreviation and .get_logo_filename_variations
(src/logo_downloader.py) and LogoHelper.normalize_abbreviation
(src/common/logo_helper.py) all do -- and nothing in the tree requests
a lowercase league logo, so the uppercase name is what the code
actually asks for. For NHL that is also the higher-resolution asset.

Removed with `git update-index --force-remove` so the literal index
entry is dropped without the case-insensitive working tree deleting the
survivor.

ChuckandClaude Opus 5 eae063700f test(sports): pin the four-case sunset matrix before B6 runs (#505)
B5 and B6 make different promises about an adopted scoreboard, and only the
second is obvious. The table:

                     | bundled copy present   | bundled copy removed
  pinned old core    | loads (the fallback)   | ERROR, naming the module
  current core       | loads, using core code | loads, using core code

The top-left cell is the one worth having. Nothing in the suite proved that an
adopted plugin still runs on a core predating src.common.sports_scroll, and
that claim is the entire basis for having shipped B5 ahead of B6's gate.

The bottom-left cell is asserted through PluginManager.load_plugin rather than
a bare import, deliberately. The manager catches the ModuleNotFoundError, so a
test written around pytest.raises would pass against a core where the module is
merely broken rather than absent, and would say nothing about what the user
meets: a plugin parked in ERROR and one log line. The assertion is the ERROR
state plus an error naming the module, which is what makes the log actionable.

Modelling notes, both of which were wrong first time and matter:

- The copy-removed shape is an UNGUARDED import, not the guarded one with the
  legacy file deleted. Keeping the guard while removing its fallback only
  mislabels the failure -- the plugin reports a missing scroll_display_legacy
  and never mentions the core module that is actually absent.
- Only the leaf module is hidden. A pre-3.2.0 core still ships src/common/;
  hiding the package would be a harsher core than any that shipped, and would
  make the failure name the package instead of the module.

Ablation: disabling the old-core simulation fails three cells, and dropping the
error object from load_plugin's set_state fails the fourth, so none of it
passes vacuously. The install gate -- the other half of the guarantee -- stays
in test_plugin_compatibility_gate.py rather than being duplicated here.

version floor".

ChuckandClaude Opus 5 af96bd5cb0 fix(memory): join an in-flight fetch instead of starting a duplicate (#503)
* fix(memory): join an in-flight fetch instead of starting a duplicate

submit_fetch_request() had no notion of "already fetching this". request_id
embeds a millisecond timestamp, so every submit looked new, and
active_requests is keyed by that id rather than by what is being fetched.
Two submits for the same cache_key therefore started two identical fetches.

It is not a rare race. _fetch_data in the sports managers branches: the Live
manager fetches only today's games, but Recent and Upcoming both pull the
full season schedule under the SAME cache_key. On a cache miss both miss,
both submit, and nothing stops the second. On a running 512x64 board:

    138 background fetches in 24 hours, arriving in pairs at identical
    millisecond timestamps, roughly hourly:

      2  2026-08-25 11:47:26.612
      2  2026-08-25 10:46:28.064
      2  2026-08-25 08:01:55.962

Half of them redundant. Each duplicate costs a second download, a second
JSON parse -- the expensive part on a Pi -- and a second parsed copy
resident at the same time. Schedules on that board run 256KB to 20MB, 106MB
across all sports. Because the pairs land in the same millisecond they also
occupy two of the three executor slots with identical work, which is what
makes two large parses peak simultaneously.

A submit for a cache_key already in flight now joins that request: its
callback is added to the existing one and the existing request_id is
returned, so get_result() works for both. Different keys are untouched, and
dedupe applies only while a fetch is in flight -- a submit after completion
fetches again, because this is not a second cache layer.

Three details:

  - The in-flight entry is dropped and the callback list snapshotted in the
    SAME critical section as filing the result. Otherwise a submitter could
    join a fetch whose callbacks had already run and never be called back.

  - Cancellation is the other way a request leaves active_requests, so it
    releases the key too. And the join path looks the request up rather than
    trusting the id, so an entry stranded any other way cannot wedge a key
    permanently -- it is dropped and a fresh fetch starts.

  - One callback raising no longer prevents the others being delivered.
    Previously there was only ever one.

Interaction with #499, whichever merges second: that PR releases the payload
after the callback runs. With several callbacks the release must happen
after ALL of them, and must not happen at all if a joined submitter passed
no callback, since polling get_result() would then be its only delivery
path. The callback list built here is the hook for that.

test_background_fetch_dedupe.py -- 8 tests, covering the join, callback
delivery to both submitters, one callback raising, distinct keys not being
coalesced, a post-completion submit fetching again, cancellation releasing
the key, a stranded entry not wedging one, and the reported count. Verified
non-vacuous by removing only the join branch: 3 fail. The callback tests
assert the ids coalesced, without which they would pass trivially on two
independent requests.

Full suite: 3698 passed, 60 skipped, 1 failure that reproduces identically
on unmodified main (test_install_lowmem, environment-dependent: /var/tmp is
disk-backed on this machine).

* fix(memory): discard a cancelled fetch instead of letting it commit

Review follow-up on the dedupe.

Cancelling releases the cache_key, so a replacement fetch for that key can
start immediately. But _fetch_data_worker() had no cancellation check: the
cancelled worker still wrote its response to the cache, flipped its own
status from CANCELLED to COMPLETED, and ran its callbacks. The stale
response could therefore land on top of the replacement's fresher data.

The worker cannot abort an HTTP call in flight, so the response is discarded
on return instead: no cache write, no callbacks, status left CANCELLED. The
check sits immediately before the cache write, which is the first
side effect.

Also fixed, found by the new test rather than by reading:

    request_id was f"{sport}_{year}_{milliseconds}", which is not unique.
    Two submits inside the same millisecond produced the SAME id -- the
    test's two sequential fetches collided on a fast mocked response, and
    one request silently replaced the other in active_requests and
    completed_requests. Rare before this PR; load-bearing now, because
    dedupe hands that id back to every joiner as their handle for
    get_result(). A per-service counter is appended.

Two test problems of my own, both fixed here rather than left to flake:

  - The cancellation test synchronised with time.sleep(0.4). A slow worker
    would have made it pass for the wrong reason. It now waits for the
    request to be filed in completed_requests.
  - The id-uniqueness test patched session.get, but submits are async: the
    50 workers outlived the patch and made real DNS calls to the dummy host.
    It stubs the executor instead, which is what a submit-time test should
    exercise.

20 consecutive runs of the dedupe file: 0 failures. Full suite: 3700 passed,
60 skipped, 1 failure that reproduces identically on unmodified main
(test_install_lowmem, environment-dependent).

* fix(memory): make cancellation terminal, not advisory

Three paths wrote request.status without checking whether the request had
already been cancelled, so a cancel could be silently undone and the work it
was meant to stop went ahead anyway.

- A request cancelled while queued had CANCELLED overwritten with IN_PROGRESS
  the moment its worker started, defeating the discard check entirely: it
  downloaded, cached and called back for work the caller had withdrawn. It
  now skips the fetch outright, which is also the cheapest possible cancel.
- The cancelled-check and the cache write were separate critical sections, so
  a cancel landing between them left the payload in the cache with the
  callbacks suppressed -- every submitter that joined the fetch waited for a
  call that never came. The worker now claims the commit in the same critical
  section that reads the status, and cancel_request refuses once claimed. The
  write stays outside the lock: it serialises a multi-megabyte payload to the
  SD card, and holding the service lock across that would stall every submit,
  status query and cancel behind it.
- A cancelled request that then failed was relabelled FAILED, which slipped
  past the CANCELLED-only callback gate and delivered a spurious error
  callback. The except path now leaves CANCELLED alone.

get_request_status() also reported a cancelled request as FAILED, since it
inferred status from result.success; the final status is now recorded on the
result. Both early returns assign to `result` so completed_requests files the
outcome that was reported rather than the untouched placeholder.

Tests cover cancellation before worker start, during the commit, and during an
HTTP failure; all three fail against the unfixed code.

* test(memory): reach the exception path as a cancelled request

test_a_failure_after_cancelling_stays_cancelled cancelled the request while
its worker was still queued, so once the pre-start branch landed the worker
returned there and never reached the exception handler the test is named for.
It passed against the unfixed code only because that branch did not exist yet;
with it, the test passed for the wrong reason and reverting the except-path
guard did not fail it.

Cancel while the worker is parked inside the HTTP call instead, and assert the
fetch actually started so the test cannot silently degrade into the pre-start
case again. Reverting each of the three guards now fails exactly one test.

Also read the payload inside the callback rather than off the FetchResult
afterwards: #499 releases result.data once delivery is done, so the later read
saw the released object and not what the caller was handed.

ChuckandClaude Opus 5 bdced206dc fix(plugins): retain state history by age, with the count as a ceiling (#502)
* fix(plugins): retain state history by age, with the count as a ceiling

Follow-up to the cap in this PR. A flat entry count answers the wrong
question: what a reader wants from this history is "the last couple of
hours", and how many transitions that is depends entirely on the plugin's
update interval. On a real board those span 2s to 3600s, so 200 entries is

    interval   200 entries covers
        2s          3.3 minutes     (flights, live)
       10s         16.7 minutes     (jellyfin)
       60s          1.7 hours       (default)
      300s          8.3 hours       (news)
     3600s          4.2 days

-- the plugin churning hardest, the one worth looking at, keeps the least.

So transitions are now trimmed by AGE first
(STATE_HISTORY_MAX_AGE_SECONDS, two hours), which makes the retained window
comparable whatever the cadence, and the count cap becomes purely a memory
ceiling for pollers fast enough to exceed it inside that window. The
ceiling rises 200 -> 2000: at ~230 bytes an entry that is ~0.5MB per plugin
worst case, and only plugins updating faster than roughly every 4s can
reach it. Steady-state memory is unchanged for everything slower, since the
age trim binds first.

Two details worth stating:

  - The trim reads time.monotonic(), stored alongside each transition,
    rather than the datetime already inside it. A DST shift or an NTP step
    would otherwise make every entry look ancient and flush the history in
    one go. The human-readable timestamp is untouched and still what
    get_state_history() returns.

  - Trimming happens on append, so a plugin that goes quiet keeps its last
    window until it writes again. That is deliberate: it is bounded either
    way, and a lazy trim costs nothing on the hot scheduling path. The
    guarantee is therefore about the SPAN of retained history, not its age
    against the current clock, and the test asserts it that way.

The public shape is unchanged: get_state_history() still returns the same
list of transition dicts, and state_history_count is still the lifetime
total.

test_plugin_state_history_retention.py adds 7 tests. Verified against this
branch with only the age trim removed: 4 fail, 3 pass -- the three that
survive are testing the count ceiling and the monotonic clock, which this
commit does not change. Full suite 3753 passed, 60 skipped.

* fix(plugins): build get_state_info() as one locked snapshot

Every field was read under its own lock, so an unload running concurrently
could be observed half-done: 'state' read before clear_state() removed it
and 'state_history_count' read after, handing PluginManager.get_plugin_info()
a plugin that is ENABLED with zero transitions.

The whole payload is now built in one critical section. _lock is an RLock,
so the helpers called inside it can still take it.

The regression test runs a reader against a thread that repeatedly fills and
clears the same plugin, and fails on the first torn snapshot. Verified by
removing only the lock: fails on 3 of 3 runs, passes on 3 of 3 with it.

Ron PierceandClaude Opus 5 39e7f8cbe0 fix(plugins): cap the per-plugin state transition history (#501)
* fix(plugins): cap the per-plugin state transition history

PluginStateManager recorded every state transition in a per-plugin list
and never trimmed it. The only code that removed entries was
clear_state(), called solely from PluginManager.unload_plugin(), so a
plugin that stays loaded -- normal operation -- never released one.

The list is written on the hot scheduling path. Every update cycle
appends twice: _reserve_for_update() sets RUNNING and _finish() sets
ENABLED back again. At the default 60s update interval that is 2,880
entries per plugin per day, and nothing reads them -- get_state_info()
only takes their len(). Pure dead weight.

Measured against the unpatched class, ten plugins on a 60s interval:

    sim uptime   history entries   heap growth
          1 day           28,810        7.7 MB
          7 days         201,610       53.9 MB
         30 days         864,010      230.9 MB   (still climbing)

With the cap it is flat at 2,000 entries / 0.5 MB from day one.

On a 1 GB board 231 MB of garbage is fatal on its own, and the failure
is not a clean OOM: once MemAvailable falls far enough fork() starts
returning ENOMEM, so sshd accepts connections and closes them before its
banner while the kernel still answers pings. The board looks like a
hardware fault and needs a power cycle. Same family as the ceilings
added in #464.

Retain the most recent 200 transitions per plugin in a deque and let the
rest age out. state_history_count is surfaced through the web API, so
the lifetime total is tracked separately rather than plateauing at the
cap. get_state_history() now returns a copy under the lock; it was
handing out the manager's own list, which a caller could mutate.

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

* fix(plugins): copy history entries out, lock clear_state

Review follow-ups on the transition history.

get_state_history() copied only the outer list, so a caller holding a
returned transition could rewrite the manager's record of what happened
-- which contradicted the defensive-copy guarantee in its own docstring.
Copy each entry too. Every value in a transition is immutable, so a
shallow copy per entry is enough. test_get_state_history_entries_are_copies
pins it; without the change it fails with 'tampered' == 'enabled'.

clear_state() mutated five shared dicts without holding _lock, while
every other mutator takes it. A concurrent set_state() could interleave
and leave a plugin with history but no state. Drop the five as one unit.

This does not close the wider unload-vs-worker race, which lives in
PluginManager.unload_plugin() and predates this change: an update worker
still in flight can call set_state() after clear_state() returns and
recreate the entry. Serialising that needs the per-plugin lock held
across worker join in unload_plugin(), which is a separate change.

ChuckandClaude Opus 5 f90638a9ec feat(web): show available memory in Tools diagnostics (#500)
* feat(web): show available memory in Tools diagnostics

System Diagnostics reported memory as used-percent plus used/total GB.
Neither distinguishes a healthy board from one about to fail, because
page cache counts as used and is reclaimable on demand -- a Pi can read
70% used and be fine, or read the same and be minutes from trouble.

MemAvailable is the kernel's own estimate of what a new allocation can
actually obtain, and it is the number that tracked the failure on a 1GB
Pi 3B+: healthy running sat above 500MB, and the crash came at 73MB. By
that point fork() was failing, so sshd could not spawn a session and
systemd could not respawn the display, while the kernel carried on
answering pings at 0% loss. Used-percent gave no warning at any point on
the way there; available memory fell steadily for hours.

/api/v3/system/status now returns memory_available_mb from
psutil.virtual_memory().available, and Tools renders it as its own tile,
coloured against the thresholds that failure implies: red under 150MB,
amber under 300MB, green above.

The existing memory tile is left alone -- used/total is still what you
want when sizing a workload; this answers the different question of how
much room is left right now.

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

* fix(web): round available memory once, so the tile agrees with itself

The colour was classified from the raw value while the label was rounded,
and the API sends one decimal place. At the boundaries the two disagreed:
149.6 rendered as "150 MB" in red, and 299.6 as "300 MB" in amber -- each
contradicting the threshold its own colour claims to apply ("red under
150MB"). A reader checking the tile against the documented thresholds would
conclude the readout was broken.

Rounding once and using that number for both restores agreement. It moves
those two boundary cases up a band, which does not matter: the thresholds
come from a measured failure at 73MB, so which side of the line a spare
0.4MB falls on carries no information. The tile agreeing with itself does.

Null handling and the thresholds themselves are unchanged.

ChuckandClaude Opus 5 333fd17d28 fix(memory): release fetched payloads once they have been delivered (#499)
* fix(memory): release fetched payloads once they have been delivered

BackgroundDataService kept the fetched body on the FetchResult it filed
in completed_requests, which is swept hourly and capped at 500 entries
by count. For a status record that costs nothing; for a season schedule
it costs a tenth of the board.

Measured on a 1GB Pi 3B+ with a 1-second RSS profile: the display
process sat at 404MB after plugin load, then stepped +21MB when NFL
fetched its season and +90MB when NCAA football fetched 946 games for
2026 -- and stayed at 494MB. Not a leak; a staircase that never came
down. When a later fetch landed while headroom was low, available memory
reached ~70MB, fork() began failing, and the board stopped being able to
start a process at all: sshd accepted connections and closed them before
its banner, systemd could not respawn the display, and the panel went
dark while the kernel carried on answering pings.

The cache-hit path was the worse of the two. It runs once per update
interval per sport, mints a fresh request_id each time, and files
whatever the cache returned. The memory tier is capped at 150 entries on
a 1GB board, so a miss re-parses the payload from disk into a genuinely
new object -- separate copies accumulating toward the 500-entry cap,
not shared references.

Releasing is safe: the payload is written to the cache under the
request's cache_key before the result is built, the callback is handed
the object directly, and consumers read it back from the cache
afterwards (the plugins' callbacks use it only in passing, to log a
count, before reading the cache). Nothing is lost -- it moves from RAM
to the disk cache that was already holding it.

Requests submitted without a callback keep their payload, since polling
get_result() is then the only way to collect it. That keeps the existing
contract, and the existing tests covering it, intact.

Not addressed here: max_workers=3 allows three concurrent fetches, so
three large parses can peak at once, and there is no in-flight dedupe by
cache_key -- a second submit for a key already being fetched starts a
second fetch. Both bound the transient peak rather than what stays
resident, and both are behaviour changes worth their own review.

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

* fix(memory): file the cache-hit result before running its callback

Restores the original ordering. Releasing the payload after the callback
meant filing the result after it too, so a callback that queried
get_result() or is_request_complete() for its own request would not have
found it -- a behaviour change unrelated to the memory fix.

The dict holds a reference to the same object, so releasing after filing
still clears the payload.

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

* test: wait for the payload release, not just the filing

The callback test waited on is_request_complete(), which goes true as soon
as the worker files the result in completed_requests. The worker then runs
the cleanup pass, then the callback, then releases the payload. Both of the
test's assertions therefore raced the worker: `seen` is populated by the
callback, and `data is None` only after the release that follows it.

It passes today because a one-line callback usually finishes inside the
20ms poll interval. Confirmed by making the callback sleep 0.4s: _wait()
returns with seen == {} and the payload still resident.

_wait_for_release() polls for the released payload instead. Release happens
strictly after the callback returns, so a released payload also means the
callback has finished and one wait covers both assertions. Verified against
the same 0.4s callback.

_wait() stays for the other three fetch-path tests, which assert only what
is already true when the result is filed -- the success flag, the error,
and the cache write that happened during the fetch itself. Its docstring
now says so, so the next reader picks the right one.

ChuckandClaude Opus 5 a4a55a23fc fix(web): reject non-finite JSON numbers instead of raising (#497)
* fix(web): reject non-finite JSON numbers instead of raising

POST /api/v3/config/dim-schedule with {"dim_brightness": Infinity} answered
500. So did /api/v3/errors/clear with max_age_hours, and /api/v3/config/main
with multiplexing or row_address_type.

json.loads accepts Infinity/-Infinity/NaN by default -- they are not valid
JSON, but Python's parser emits them -- and Flask's get_json passes them
straight through. int(float('inf')) raises OverflowError, which is neither
ValueError nor TypeError, so validation blocks that carefully caught those let
it past and Flask turned it into a 500.

The status code was not the real damage. dim-schedule answered with
CONFIG_SAVE_FAILED and suggested "Check file permissions on config directory"
and "Check available disk space" for what was an invalid number. Every one of
these sites already had a correct 400 response written; they just never
reached it.

NaN already returned 400, because int(nan) raises ValueError. That is why this
only ever showed up for the infinities, and why it survived: the obvious test
case passes.

OverflowError is now caught alongside ValueError/TypeError at the 27 sites in
this file whose try block performs a numeric coercion. An AST sweep confirms
no int()/float() of request-derived data is left outside a block that catches
it.

Verified end to end through Flask's test client rather than by reasoning about
the parser: all four routes returned 500 before and 400 after.

Tests: five Infinity cases (which fail against the previous except tuples),
two NaN cases pinned so narrowing the tuple cannot quietly break them, and a
check that ordinary input is not rejected by the widened guard.

Claude-Session: https://claude.ai/code/session_01STMbQE4YctTacQXfbYqKuW

* test(web): assert 400 exactly, and prove valid input is accepted

Both review points were right, and the first is the failure mode this file
exists to catch.

Accepting any 4xx meant a 404 would have passed. Renaming one of these routes
would have left the test green while it tested nothing -- the same "looks like
coverage, points somewhere safe" shape that hid the composer injections. Now
asserts exactly 400.

Both infinity signs are exercised for every route. int() raises OverflowError
either way, but only +Infinity was in the original report, and a guard that
special-cased the sign would have passed a one-sided test.

The valid-input test previously asserted "not a 400", which did not show what
it claimed: the mocked save path fails for any input, so that assertion held
whether or not validation had accepted the value. It now gives load_config a
real dict and stubs _save_config_atomic, so the endpoint reaches its success
response and the test can assert 200 -- which only happens if the value passed
validation.

8 of the 11 checks fail with OverflowError removed from the except tuples.

ChuckandClaude Opus 5 085fb93a87 test(logging): stop the location assertion matching the clock (#496)
test_location_toggle asserted that ":42" -- a bare colon plus the record's
hardcoded lineno -- is absent from a line formatted with include_location=False.
But every formatted line starts with an HH:MM:SS.mmm timestamp, so ":42" also
matches the clock whenever the minute or the second is 42. The test fails for
roughly 3% of runs with nothing wrong:

  2026-08-22 08:05:42.274 - INFO - test.logger - hello
                     ^^^ matches ":42"

Assert on the whole "module.funcName:lineno" token the format string actually
emits ('%(module)s.%(funcName)s:%(lineno)d') instead of a fragment of it. That
cannot collide with a timestamp, and it checks the thing the test is named for.

Confirmed by formatting a record stamped 08:42:42 -- both minute and second
colliding: the old assertion fails, the new one passes.

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

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

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

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

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

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

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

Addresses the review finding on the cross-thread reads.

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

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

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

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

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

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

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

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

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

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

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

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

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

ChuckandClaude Opus 5 5a1f121e6b Stop array-item secrets being wiped, and logging them (#493)
Three review findings from #485 that I missed when addressing that PR;
it has since merged, so they land here.

1. Array-item secrets destroyed by any unrelated save (data loss).

remove_empty_secrets recursed into dicts but let a list fall through to
the scalar branch and kept it verbatim. Lists merge by *replacement*, so
the blanks the masked form posts back went straight over the stored
array:

    stored   [{"name":"a","token":"REAL-A"}, {"name":"b","token":"REAL-B"}]
    posted   [{"name":"a","token":""},       {"name":"b","token":""}]
    merged   [{"name":"a","token":""},       {"name":"b","token":""}]
             -> both credentials gone

Same failure as the scalar api_key case fixed earlier, one container
deeper. Lists now prune element-wise, and a list with nothing real in it
is dropped so the stored one is left alone. Where one entry does change,
the new merge_secrets merges by index instead of replacing.

Two details the first attempt got wrong, both caught by existing tests:

- An emptied dict item must stay {}, not None. ConfigManager's
  _strip_secrets_recursive treats a secrets list as *parallel* to the
  regular one ({} = "item i has no secrets"); a None makes it stop
  looking parallel, and it then drops the whole key from the main config
  -- silently deleting the items' non-secret fields too.
- The incoming list's length wins. The regular config's list is
  authoritative about how many items exist, so preserving surplus stored
  entries would let the two fall out of step and make deleting an entry
  impossible.

2. Submitted credentials written to the journal (security).

save_plugin_config logged `Full config: {plugin_config}` at INFO and
`Config that failed: {plugin_config}` at ERROR. Both run before
separate_secrets, so plugin_config still held the values just typed into
the form. Now keys only. Swept the rest of web_interface/ and src/ for
the same shape -- these were the only two.

3. Restart banner kept stale wording.

showRestartPending() cleared the stored custom text but left the DOM
element alone, so a config save could show the previous update's
message. The default is read back from the server-rendered copy rather
than duplicated in JS, so the template stays the one owner of the string.

Verified: 556 passed, 1 skipped across the web suite. Mutation-checked --
reverting api_v3 fails the logging guard and the array-merge test;
reverting either half of the secret_helpers change fails the unit tests.
New end-to-end coverage drives the real endpoint, not just the helpers.

    assert call("lm_disk_backed_tmpdir", env={"TMPDIR": str(tmp_path)}) == ""

That premise is false on the platform the helper was written for. Debian
13 mounts /tmp as tmpfs -- which is the entire reason lm_disk_backed_tmpdir
exists -- and pytest puts tmp_path under /tmp. So on the target platform
TMPDIR is memory-backed, the helper correctly answers /var/tmp, and the
test fails:

    E  AssertionError: assert '/var/tmp' == ''

The helper is right; the test was wrong. Reproduced on a box where
/tmp is tmpfs and / is ext4.

The test now looks for a directory whose backing store is actually disk
-- tmp_path, else a scratch dir under /var/tmp, else beside the library
-- using the same findmnt lookup the helper itself uses, and skips only
if no disk-backed directory exists anywhere. An earlier version of this
fix skipped whenever tmp_path was tmpfs, which made it skip on every
machine with a tmpfs /tmp; that is barely better than asserting the
wrong thing, so it now searches instead of giving up.

Verified: 31 passed, 0 skipped. Mutation-checked -- deleting the
"is the current TMPDIR memory-backed?" guard from lm_disk_backed_tmpdir
fails this test, so it still catches the regression it is there for.

ChuckandClaude Opus 5 568cb6d77f 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.

ChuckandClaude Opus 5 6b74506695 fix(sports): fetch odds for the games shown, not the whole schedule window (#494)
* fix(sports): fetch odds for the games shown, not the whole window

SportsUpcoming.update() walked every upcoming game in the schedule
window and called _fetch_odds() on each one inside that collection
loop, narrowing to upcoming_games_to_show only afterwards. Each call is
a separate sequential ESPN request.

The comment sitting above it said odds were fetched "only for games that
will be displayed". The only narrowing it actually applied was
show_favorite_teams_only, which is not the default, so in the usual
configuration nothing narrowed it at all.

Measured on devpi, where the football plugin has the same shape:

  467 odds requests in one 35s burst, 467 distinct events
  315 NFL + 152 college-football -- roughly a whole season
  plugin football-scoreboard operation timed out after 30.0s

The burst repeats each time the 1h odds TTL expires: 67 -> 327 -> 957 ->
1261 requests/hour across four consecutive hours. Between expiries the
cache works and the rate is zero, so this is a thundering herd on
expiry, not a caching failure.

The fetch now runs after selection, over team_games -- the list already
cut to upcoming_games_to_show. This mirrors the fix the football plugin
already carries; the shared base class never got it.

SportsLive is deliberately left as it is: it walks the raw event list
because it has to find which games are live, but only fetches odds for a
game that has already passed the is_live/is_halftime test, so its
fan-out is bounded by how many games are actually in progress. The test
pins that distinction rather than assuming it.

The test reads the AST rather than the source text, and asserts the full
set of call sites, so a new one has to be classified deliberately
instead of inheriting whichever behaviour it happens to land in. Writing
it that way is what turned up the SportsLive site, which I had missed.

Verified: reverting the fix fails the test with the offending iterable
named ("iterates over 'events'"). 525 passed, 9 skipped across the sports
and odds suites.

* test(sports): check the odds guard structurally, not by its text

Review caught that _guards_above() collected an `if` test even when the
call sat in that if's `else`, so moving _fetch_odds() into the else of
the is_live/is_halftime test would still pass -- while fetching odds for
exactly the non-live games the guard exists to exclude.

Verifying that turned up a wider hole in the same assertion. It matched
substrings of the *unparsed source*, so a negated condition satisfied it
too:

    if not (details["is_live"] or details["is_halftime"]):
        self._fetch_odds(details)      # every non-live game

Both names still appear in that text, so `"is_live" in guards` held and
the test passed on code doing the opposite of what it claims to check.

The guard test is now structural. It walks the AST for an enclosing `if`
whose *body* (never its `else`) contains the call, and whose test
references both names without either sitting under a `not`.

Verified by mutation: fetching odds for non-live games now fails with
"does not sit in the true branch of a test requiring the game to be in
progress". Moving the call into the else of the *favourites* test still
passes, which is correct -- the game there is still live, so the
in-progress contract holds and the fan-out stays bounded by how many
games are actually in play.

525 passed, 9 skipped across the sports and odds suites.

ChuckandClaude Opus 5 5f29243e87 fix(config): make the device location the default for plugin location fields (#490)
* fix(config): make the device location the default for plugin location fields

A user in Kansas City reported their radar centred on Dallas, TX with
nothing in config.json to explain it.

The radar is the `ledmatrix-weather` plugin's `radar` mode, and it centres
on the same coordinates as every other weather mode: `forecast_data`
lat/lon, geocoded from the plugin's own `location_city` /
`location_state` / `location_country`. Those ship with schema defaults of
Dallas / Texas / US. A user who never opened the weather plugin's config
form therefore has no `location_city` on disk, and `PluginManager` merges
the schema default in at load time — so the whole plugin (not just the
radar) silently runs on Dallas. Radar is just the only mode that draws a
recognisable map and gives the mismatch away.

Meanwhile the device-wide `location` block that General settings writes
was read by nothing at all, despite its own help text promising it was
"used for weather, sunrise/sunset, and other location-based content".

`SchemaManager.generate_default_config()` now substitutes the device
`location` into the three fully-namespaced `location_*` keys before
handing defaults back, so the promise holds:

- Only `location_city` / `location_state` / `location_country` are
  substituted. A bare `state` key is left alone — `ledmatrix-elections`
  uses it for a two-letter code, and rewriting it would break that plugin.
- A value the user saved on the plugin still wins: this replaces the
  schema default, and `merge_with_defaults` puts user config on top.
- The substitution is applied on the way out of the defaults cache rather
  than into it, so changing the device location takes effect immediately.
- No config manager, no `location` block, or an unreadable config all
  fall back to the plugin's own schema defaults.

Every caller benefits: the plugin loader, the config form (which now
pre-fills the user's real city), config save, and reset-to-defaults.

* docs(web): name the exact plugin keys the device location seeds

Review follow-up. The General settings help text said the device location
was "the default for every plugin that asks for a city", which overstates
what the code does: only the fully-namespaced `location_city` /
`location_state` / `location_country` keys are substituted. A plugin with
a bare `city` key gets nothing — deliberately, since `ledmatrix-elections`
uses `state` for a two-letter code. The tips now name the exact keys.

Worth noting for anyone editing these: `ui.help_tip(...)` takes a
single-quoted Jinja string, so an apostrophe in the tip text has to be
escaped or written around. The wording here avoids them.

ChuckandClaude Opus 5 1fbe244e49 fix(plugins): say when discovery skips a directory (#489)
* fix(plugins): say when discovery skips a directory

A plugin can be enabled in config, enabled in plugin state, present on disk
with a valid manifest and an importable entry point -- and simply absent from
the running process, with nothing anywhere to say why.

That is not hypothetical. hockey-scoreboard on a live rig is enabled in both
places, imports cleanly when loaded by hand, and is listed in the Vegas plugin
order, but is not among the 22 plugins the process actually holds. Establishing
even that much meant comparing cache-file mtimes to find it had last run three
days earlier. The journal had nothing, because discovery does not report what
it declines to load.

Two paths were silent. A directory with no manifest.json was skipped without
comment, which is defensible until it is the thing you are trying to explain.
Quieter still, a manifest that parsed but carried no "id" was read
successfully and then dropped on the floor -- no warning, no trace, and the
plugin simply does not exist as far as the rest of the system is concerned.

Both now log a warning naming the directory and the reason.

This does not explain the rig above; its manifest has an id. It makes the next
occurrence diagnosable from the journal instead of from file timestamps.

Reverting the change fails both tests. 65 plugin-system tests pass.

* fix(plugins): warn once per directory, not once per scan

Self-review catch. Discovery runs on every web UI page load and every config
reconcile, so warning unconditionally about an unloadable directory would put
a line in the journal each time someone opened a page -- the same log-volume
problem this change exists to help diagnose.

The skip is now reported once per directory per process. The diagnostic value
is unchanged: the reason a plugin is missing still appears in the journal,
once, where before it appeared nowhere.

Test added covering five consecutive scans producing one warning.

* fix(plugins): one unusable manifest no longer aborts the whole scan

json.load accepts any JSON value, so a manifest.json holding null, [],
"text" or 42 parses without complaint and then raises AttributeError on
manifest.get('id'). Nothing catches that: the outer handler around the
scan takes OSError and PermissionError only.

So a single malformed manifest did not skip that one directory -- it
aborted _scan_directory_for_plugins outright, and every other plugin on
disk, however healthy, silently failed to register. Reproduced with
three directories, the middle one holding `null`:

    SCAN ABORTED -> AttributeError: 'NoneType' object has no attribute 'get'
      the two valid plugins never registered

That is the same failure this PR set out to fix, in its most severe
form: a plugin enabled in config, enabled in plugin state, present on
disk, and absent from the running process with nothing to say why --
except here it takes every other plugin with it.

A manifest that is not a JSON object is now skipped like any other
unusable directory, named once, with what it actually was:

    Skipping bad-null: its manifest.json is NoneType, not a JSON object
    Skipping bad-list: its manifest.json is list, not a JSON object
    scan returned: ['aaa-good', 'zzz-good']

Verified: removing the guard fails 6 of the 10 tests. Covers null, list,
string, int and bool, and asserts the healthy plugins either side of the
bad one still register.
