The backfill is right, and it lands on a path that could not carry it yet.
deriveMediaMetadata spawned ffprobe and ffmpeg with execFileSync, each with a
15s timeout. Synchronously, those two calls stop the whole server for their
duration: no heartbeats, no socket traffic, no HTTP. That was survivable while
the only caller was a human-initiated upload — one file, someone waiting on it,
bounded by their patience.
The boot-time sweep removes every one of those mitigations. It walks the entire
library, unattended, on a server with live panels, once per boot. A library of
video rows therefore becomes a per-file event-loop stall, which is #240's
failure mode — blocked loop, missed heartbeats, panels marked offline,
reconnect churn — arriving from our own maintenance instead of from a
checkpoint. We spent yesterday removing one of those; this would have added
another, on a schedule.
So both spawns are awaited instead of blocked on. Both callers already awaited
deriveMediaMetadata, so this is invisible to them, and the ingest path stops
freezing the server for the length of an upload's probe as a side benefit —
that sync ffprobe has been known tech debt for a while.
Timeouts are unchanged and still asserted: async is not a licence to hang, or
one wedged file stops the sweep dead instead of moving on.
Also applied the PR's own phantom-path discipline to the video branch, which
still named its thumbnail before the encode: a failed ffmpeg left the row
claiming a file that was never written, which is the exact bug the image branch
was fixed for two commits earlier.
The new test measures the property rather than grepping for it — a timer keeps
ticking across a real spawn — so a future edit that reintroduces a sync call
fails here rather than in a customer's fleet.

Two field-reported gaps, unrelated except that both are about being able to
read something off a screen.
A PANEL'S IPv6 WAS NEVER COLLECTED, LET ALONE SHOWN.
DeviceInfo.getLocalIp() filters to Inet4Address, so a v6-only panel reported no
address at all and the dashboard rendered a dash for a screen that was perfectly
reachable. It now reports both stacks in their own fields: a dual-stack panel
genuinely has two addresses and either may be the one you need, so collapsing
them into one column would make it mean "whichever interface enumerated first".
Link-local (fe80::/10) is deliberately excluded. Every interface has one, they
tend to enumerate first, and none can be dialled without also knowing the zone
index — so admitting them would fill the field with a string nobody can paste
anywhere and hide the address that works. Any %iface suffix is trimmed for the
same reason. The 45-char cap the writer already applied is exactly the longest
legitimate IPv6 text form, so it needed no change.
The dashboard card renders only when a panel actually has a v6 address, rather
than showing an empty row to the overwhelmingly v4 fleet.
THE PAIRING CODE DID NOT SCALE, WHICH IS WORST WHERE IT MATTERS MOST.
Every size on the pre-playback screens was a hard-coded pixel value. A CSS pixel
covers a quarter of the screen area on a 4K panel that it does on 1080p, and a
sixteenth on 8K — so the 72px code that fills a 1080p screen is a smudge on the
4K wall it was installed on, which is where signage actually goes.
What has to stay constant is ANGULAR size, so the root font size is now
viewport-proportional and everything on those screens is a rem against it. The
code holds 6.67% of screen height at every resolution: 72px at 1080p — bit for
bit what it renders today, so nothing changes for the existing fleet — 144px at
4K, 288px at 8K. Verified in a browser rather than by arithmetic: at a 1409px
viewport the root computes to 13.0473px, which is 0.926vmin to four decimals.
vmin, not vw, because portrait-mounted panels are common here and vw would
render a 1080x1920 screen at half size. Clamped at both ends so the dashboard's
preview iframe stays legible instead of microscopic and an ultrawide does not
get silly. Applied to the web player (which BrightSign also runs) and to Tizen,
where a 1920x1080 logical viewport makes it arithmetically identical to the
values it replaces — the point being the panels where it is not.
A test asserts the scaling cannot reach playback content: the whole safety
argument is that only the chrome uses rem, and a stage or zone rule adopting it
would start resizing CONTENT, which is a worse bug than the one being fixed.
Android is untouched — its pairing code already autosizes within a dp-scaled
layout.

Ingest-time thumbnail generation is best-effort by contract, so a row that
misses it stays bare forever: video uploads on a host without ffmpeg (a
SYSTEM dependency nothing surfaced), or content from before thumbnails
existed. Operators read that as "thumbnails don't work".
Two additions. A [MEDIA] startup diagnostic (async probe, cached) states
loudly whether ffmpeg/ffprobe were found, mirroring the [EMAIL] block. And
a once-per-boot sweep re-derives metadata for local image/video rows with
no thumbnail — serial, paced, delayed past boot, unref'd. The sweep's row
UPDATE re-checks that thumbnail_path is still empty so it never clobbers a
thumbnail written concurrently by the replace flow, removes its just-written
file when the row vanished mid-derive, salvages probed dims/duration even
when the thumbnail itself failed, and stops after 25 failures per boot so a
library of undecodable clips can't turn every restart into subprocess churn.

deriveMediaMetadata assigned thumbnailPath before sharp wrote the file, so
a failed write (corrupt image, disk error) returned a name for a file that
was never created. Ingest then stored that phantom thumbnail_path and the
dashboard requested it forever as a broken image. Assign only after the
write succeeds; the video branch already nulled its path on failure.

helmet already sets X-Frame-Options, HSTS, CSP, etc., and manages them
per route (widget/kiosk renders and the device preview remove or relax
X-Frame-Options so they can be framed). A proxy-level header block adds
a second copy, and browsers treat conflicting duplicate X-Frame-Options
values as deny - which blanks the same-origin /player iframe behind the
dashboard's Preview button. Seen in the wild behind a Caddy config that
added X-Frame-Options: DENY on top of the app's SAMEORIGIN.

The server already acks dashboard:request-screenshot with
{ delivered, reason } (offline / unsupported via the capability
registry), but no dashboard sender passed a callback, so clicking
Screenshot on an offline device or an unsupporting player type showed
"Screenshot requested" and then silently did nothing.
requestScreenshot() now takes an optional callback using the same
.timeout(5000) pattern as sendCommand(); the device-detail Screenshot
button passes one and toasts the verdict (requested / unsupported /
offline / no response). The dashboard grid and the 5s Now Playing poll
keep firing-and-forgetting - no behavior change there.

Two changes that are really one idea: the parity model treated all four
players as if they update the same way, and they do not.
WEB AND BRIGHTSIGN GET audio.volume BACK.
The audit removed it because v1.9.28's index.html contained the string
set_volume zero times, and because the handler read payload.value while the
dashboard sends { level }. The second reason 1.9.31 fixed. The first was
reasoning from the wrong artifact: this player is SERVED BY THE SERVER, so a
browser panel runs whatever build is answering it, not the release its row was
created under. There is no browser panel stuck on the v1.9.28 player once the
server moves — and prod moved tonight. The slider works on those displays right
now while the baseline says it does not, so the dashboard is hiding a working
control from every display that declares nothing.
BrightSign comes with it, on the same served player. The unit-specific doubt is
whether a hwz player's media element is reachable at all — and that is already
answered by audio.mute, which this baseline has always claimed: set_volume
reaches setMediaVolume() and device:mute-changed reaches currentVideoEl.muted,
same element, same path. If hwz swallowed one it would swallow both.
TIZEN DOES NOT COME WITH THEM, AND THE TEST NOW KNOWS WHY.
A .wgt sits on the panel until somebody updates it. Cutting 1.9.31 put nothing
on any screen, so an un-updated Tizen panel still has the broken handler and
moving its baseline would resurrect the dead slider on real hardware.
The test could not express that. It judged every family against "shipped
source", resolved as the newest tag — which is HEAD on a release commit, so
tagging 1.9.31 flipped all four biconditionals at once and demanded a baseline
change for displays that cannot have the fix yet. Green tree, red build, naming
a baseline, with nothing in the diff to explain it. main would have gone red on
the next commit whatever it contained; #242 just got there first.
So the two families are now modelled separately. Server-served: judged against
the working tree, both directions, because both are decidable from the build we
are about to serve. Device artifact: judged against the previous release, and
only in the over-claim direction — "the baseline claims it, so the shipped
player had better implement it" is always true and worth failing on, while
"HEAD gained the handler, so add it" is a guess about how many panels have
updated. The cost is that a stale entry can outlive the artifact reaching the
fleet; that is a judgement about screens, so a person makes it in
player-capabilities.js and records why.
player-capabilities.test.js carried the same stale reasoning hardcoded, and
docs/player-parity.md stated the old facts in four places — a parity matrix
that lies being the exact failure this whole model exists to stop.

It still read "escalate >16MB or 3 growing runs" after #240 added a size floor
and a cooldown to that second rule. Growth-across-three-runs on its own is
exactly the half that no longer holds, so the line described a checkpointer
that does not exist — and it is the line an operator reads to learn the policy.
During an incident it would send you hunting for a blocking checkpoint that the
new gates had in fact suppressed.
[wal-checkpoint] off-thread checkpointer started (PASSIVE every 15000ms;
blocking TRUNCATE when the WAL exceeds 16MB, or after 3 growing runs but only
at >=8MB and at most once per 300s; respawn max 5/60000ms)
A test now asserts the line reports every knob that governs the decision, since
nothing else keeps a log string and the rule it describes in step. Writing it
caught its own bug first: anchoring the slice back to `return worker;` matched
the idempotence guard at the top of startWalCheckpointer(), not the log below
it, so the window was empty and every assertion passed vacuously.

Cutting 1.9.31 turned a green tree red, and the failing assertion named a
baseline rather than the tag that caused it.
"Shipped source" was resolved as the newest v* tag. That is wrong at exactly
one moment, and it is a moment that arrives at every release: on the release
commit the newest tag IS HEAD, so shipped source becomes the working tree,
every biconditional inverts, and the build demands BASELINE.web gain
audio.volume — for displays that cannot have the fix until this very release
reaches them. Tagging a release should not be able to change what the release
is allowed to contain.
A baseline describes an UN-UPDATED display, so the source it is judged against
is the release BEFORE the one being cut. Skip any tag pointing at HEAD and use
its predecessor: v1.9.30 here, and the newest tag as before during ordinary
development.

main has been red since 4f7b4e3 for a reason visible nowhere in its diff.
The player-parity baselines describe what an UN-UPDATED display can do, so
they are judged against the SHIPPED source — `git show <latest tag>:…` —
rather than the working tree. actions/checkout defaults to a shallow clone
with no tags, so that lookup found nothing and the suite fell back to the
working tree. In a tree where today's QA had just fixed the players'
set_volume payload bug, the biconditional then demanded that
BASELINE.web/tizen gain audio.volume — for displays that cannot possibly
have the fix yet. Green locally, red in CI, and the failing assertion names
a baseline rather than the checkout that caused it.
So fetch the tags in the test job, and make the biconditionals SKIP when
there are none instead of asserting against the wrong source. That fallback
was never a slightly-early assertion; it was an inverted one. A skipped
assertion announces itself, a wrong one does not.
Verified both ways: with tags 15/15 pass, in a tagless shallow clone 13
pass + 2 skip + 0 fail (previously 1 fail).

Bold reported loop lag that grew with uptime and reset on restart. The
signature they saw — mean = p50 = p99 = max, identical to two decimals —
is not a fixed cost paid on every cycle. It is what an IntervalHistogram
window reports when it recorded exactly ONE delay: the mean is the raw
value, and every percentile returns the bucket ceiling above it.
Reproduced against their exact numbers (1329.07 / 1329.59). So the loop
took one long turn that swallowed the sampling second, episodically —
which is what they later confirmed independently.
The turn is ours, and it is now measured rather than theorised. Probing
the real worker against a real WAL with one reader mid-transaction: a
single main-thread write blocked for 4,936ms behind the worker's
wal_checkpoint(TRUNCATE), which then reported WAL 8.8MB -> 8.8MB. TRUNCATE
is the blocking form and its locks are held ACROSS connections, so moving
it to a worker kept the fsync off the loop but not the lock; and it does
not throw when it cannot get those locks, it returns busy=1 having sat on
SQLite's 5s busy timeout and reclaimed nothing. Five seconds of stalled
loop for zero benefit, and silent.
It was reached far too easily. The rule was "escalate if the WAL grew
across three consecutive 15s runs" — which any sustained 45-second write
burst satisfies. A customer's fleet powering on in the morning does it
daily.
Two gates, because either alone leaves the hole open. A size FLOOR, so a
WAL in the lower half of its budget can't buy a blocking checkpoint it has
nothing to reclaim from. And a COOLDOWN, because the floor alone fixes
nothing for Bold — their WAL already sits at 6.2MB against a 16MB
high-water, above any sane floor, so every burst would still escalate.
However long the pressure lasts, our own maintenance may now stall the
loop at most once per window. The high-water rule bypasses both and is
untouched: a runaway WAL is the one case worth blocking for, so the
"WAL cannot grow forever" invariant is exactly as strong as before.
A busy TRUNCATE now says so in the log instead of reading like a success.
Also softened the adjacent path: when the worker is declared
unrecoverable, engageFallback() re-arms inline autocheckpoint on the main
connection — a state that is STICKY for the life of the process, i.e.
exactly the shape of "degrades with uptime, a restart fixes it". It used
to also run an unconditional main-thread TRUNCATE on the way in; that now
happens only when the WAL is genuinely over high-water, and the fallback
state is served on /api/status rather than being inferable only from a log
line that may have rolled.
Telemetry, so the next report is self-explanatory: loop_lag carries
`samples` (~50 when healthy, 1 when a single turn swallowed the second),
`tick_gap_ms` measured on the WALL CLOCK independently of the histogram,
and `worst_tick_gap_ms`/`worst_tick_at` — monotone, so five-minute polling
can no longer miss an episode.
Band semantics are deliberately unchanged. A one-sample window during a
real stall is the correct trigger for the shed valve; suppressing it would
blind the protection at exactly the moment it is needed.
Separately, device_telemetry gets the age sweep it never had. The
per-heartbeat row cap only ever trims the device whose heartbeat is being
handled, so a device that STOPS reporting leaves its rows behind forever.
The new sweep is per-device (rides idx_telemetry_device rather than
scanning), chunked and yielding like the device_status_log one, and
defaults to 30 days to match the uptime report's own default window — so
it cannot remove rows that report would have shown.

GetStorageStatus() is documented for SD:/SSD:/USB: only, so it can never confirm
internal flash, and roStorageHotplug may be absent entirely. Gating the probe on
it made 'cannot say' read as 'no disk': a player with an NVMe reported 1025 MB,
which is the widget's cache quota arriving through the page-side fallback.
roStorageInfo is asked directly as a second pass, with the mount check kept first
so a removable volume still wins over internal flash.

screen_off blanks a fielded panel for real (owner/admin FORCE_LOCK, else the
accessibility lock); screen_on is a logged no-op. One capability renders both
dashboard buttons, so withholding the pair to hide the dead ON button also takes
blank-at-night — the half that gets scheduled — away from every panel that has
not updated. Panels that have updated declare for themselves.

Two tests disagreed after the QA merges, and both were right about their own
half — which is what made the disagreement worth resolving rather than silencing.
A baseline describes what an UN-UPDATED display can do. The baselines were
justified against `git show v1.9.28:<source>` and then asserted against the
working tree, so the moment a player's payload bug was fixed the biconditional
demanded a baseline change for displays that cannot possibly have the fix yet. A
baseline entry moves when a fix SHIPS. It now reads the newest release tag, and
falls back to the tree when tags are unavailable (a shallow CI clone), because a
missing tag is a worse reason to fail a build than a slightly-early assertion.
While fixing it the helper threw a ReferenceError — the require was missing — and
its own broad catch swallowed it and quietly compared against the working tree
anyway. The catch now rethrows ReferenceError and TypeError. A fallback that
hides a programming error is the same failure shape as everything else this QA
pass found.
The BrightSign assertion encoded the older, more generous baseline: reboot needs
the BrightScript host bridge, and an undeclared unit is precisely the one we
cannot know has it. What that test is really pinning is that the row still
classifies as brightsign rather than decaying to `web` — so it now asserts that,
plus the video playback that is genuinely safe to assume.

#236 gave each video-wall panel a mounting rotation, which for the first time
puts a real rotation on an ancestor of the ExoPlayer TextureView. The screenshot
compositor could not express that: it pasted the video frame with an axis-aligned
Rect built from getLocationInWindow(), so on a rotated panel the frame landed
outside the capture bitmap entirely. What reached the dashboard was the plain
black that view.draw() leaves wherever a TextureView is — a panel that looks dead
while it is playing perfectly, which is the worst thing a diagnostic can say.
The frame is now placed through the same transform chain the hierarchy was drawn
with, accumulated up the parent chain the way the framework does when it draws a
child, so any ancestor rotation/translation is honoured. The bitmap is also
scaled from the surface's own dimensions rather than assumed to match the view.
Measured on the emulator, a wall panel playing video, remote screenshot vs the
adb framebuffer at the same moment (standard deviation — 0 means a flat frame):
before after
rotation 0 sd 0.439 / truth 0.430 sd 0.443 / truth 0.435 (unchanged)
rotation 90 sd 0 / truth 0.461 sd 0.448 / truth 0.448
rotation 90 sd 0 / truth 0.467 sd 0.460 / truth 0.457
rotation 90 sd 0 / truth 0.408 sd 0.463 / truth 0.466
Every rotated capture was #010101 with zero variance before; each now tracks the
real framebuffer. Rotation 0 is unchanged, and so is the ordinary fullscreen
(non-wall) path, re-measured across images and video.
No unit test: this is android.graphics.Matrix semantics against a live view
hierarchy, which the JVM test source set cannot exercise — the evidence is the
before/after measurement above. Android 151/151, server 1298/1298.

Two faults that are live on 1.9.29, both silent, both ending in a dark screen.
A missing upload answered 200 OK with Content-Type: text/html and 15KB of the
dashboard, under the immutable/30-day header the mount sets before it knows
whether the file exists. Every downloader here treats 200 as success, so a panel
stores the page AS the video and caches it for a month; Android validates the
byte count, not the type, so a correctly-sized page passes integrity and is
promoted as a valid asset. Reachable exactly when it hurts — a replace writes a
new random filename and unlinks the old one. Now a 404, with the cache header
removed.
And the service worker treated an empty playlist as "keep nothing". But
`assignments: []` is what the server sends for a device between playlists, for a
playlist never published, and from the catch when a snapshot fails to parse — so
a message that means nothing of the sort deleted every byte of media the panel
held. Only survivable while the uplink is up, i.e. exactly when the cache is
worthless.
Both regression tests drive the whole server or the real worker, because both
bugs live in the relationship between two pieces that are individually correct:
the order of two mounts, and the difference between "needs nothing" and "did not
arrive".

sw.js said its cache-first widget branch "is what lets a widget keep rendering
when the network is gone". It is not. The player mounts widgets in an iframe
sandboxed to `allow-scripts` with no allow-same-origin, so the frame is an
opaque-origin client, and a service worker does not control those — the
navigation never reaches the handler.
Measured rather than reasoned: a clock widget mounted five times over 25 seconds
of real playback in Chrome while the shell cache held zero widget entries, and a
plain fetch() of the identical URL from the controlled page was intercepted and
stored on the first try. The branch works; the player's own widgets are simply
not what reaches it.
What actually holds widgets through an outage today is the HTTP cache plus the
server's `max-age=31536000, immutable` on a rev-pinned render. That is sound in
a desktop browser and is exactly the store this module's own header says is NOT
persistent on BrightSign, which is why content caching had to exist at all. So
the comment now records the limit and names the two ways out — route the render
through a same-origin fetch and mount it as srcdoc, or grant allow-same-origin
and hand widget scripts the player's origin, which is not a trade worth making
for an offline nicety.
The test pins the security property so nobody buys the cache with it, and pins
the Cache-Control header, which is now known to be load-bearing on its own.

A newly paired panel always learns its playlist BEFORE the media arrives, so
start() finds nothing playable and the 3-second content re-check is what really
begins playback. updatePlaylist() has already seeded currentIndex = 0 for a
playlist that has not started, but the re-check advanced PAST that index — so
the first pass ran 1,2,3,0 and item 1 only appeared after the list wrapped.
On the emulator, a fresh pair with a 4-item playlist reproduced it every time:
Starting playback
Playing: red.png (index 1) <- clip32.mp4 (index 0) never got its turn
Playing: clip7.mp4 (index 2)
Playing: blue.png (index 3)
Playing: clip32.mp4 (index 0) <- 54s late, on the second pass
On a two-item playlist that is indistinguishable from "only one of the two ever
plays", which is how it was reported.
The distinction the re-check was missing is hasContentOnScreen. With content up,
currentIndex is a real position that has had its turn and the scan must move past
it. With nothing up, currentIndex is only where playback INTENDED to start, so
skipping it drops that item. PlaylistSelection.recheckIndex now makes that choice
explicitly, and playableFromIndex treats a negative index as "no position yet"
rather than wrapping onto the last item.
Verified on the emulator against the same cold start: the first pass is now
0,1,2,3,4 in order. Playback resume (#234) is untouched — it never reaches the
re-check when its target is cached, confirmed by an Activity relaunch resuming
mid-playlist as before.
Tests: 6 new cases in PlaylistSelectionTest covering both sides of the rule, the
still-downloading item, the no-position-yet start, and the empty case.

Three faults in the web player, each found by driving the shipped code in a
browser against the real server rather than by reading it.
set_volume did nothing at all. The dashboard sends `{ level: 0..1 }`
(device-detail.js: slider/100) and the Android player reads exactly that; this
player read `payload.value` and divided it by 100. Nothing in the product sends
`value`, so every browser panel acked the command and ignored it — the quietest
possible failure. Correcting only the key would have been worse than leaving it
broken: `level: 0.5` would have become 0.5%, which is inaudible and looks fixed.
The fraction is now canonical, `value` is still read as a percentage for
anything written against the old handler, and the scale is chosen by WHICH KEY
arrived rather than by the size of the number — 1 is legal in both conventions,
so a magnitude guess is guaranteed to be wrong for somebody. Parsing moved into
volumeLevelFromCommand() so it can be asserted without a socket.
setMediaVolume() also wrote `el.muted = (v === 0)`, so any non-zero volume
un-muted whatever was playing. An item an operator had deliberately silenced
started making noise the moment anyone touched the slider — reproduced live:
item flagged muted, one set_volume, muted went false. Mute has four inputs and
a fixed order (lib/media-mute.js), it is resolved when the element is mounted,
and a level is not entitled to overrule it — least of all the autoplay rule,
where unmuting without a gesture costs the video rather than winning the audio.
Volume 0 is silence on its own.
And the service worker pruned its content cache to an EMPTY keep-set.
`assignments: []` is what the server sends for a device between playlists, for a
playlist never published, and inside the `catch` when a published_snapshot fails
to parse — none of which mean "delete the media". Reproduced: three cached
assets, one empty payload, cache emptied. That is only survivable while the
uplink is up, which is precisely when the offline cache is worthless. A cache
kept too long costs disk the quota reclaims anyway.
Verified in Chrome against a live server: volume 0.42/0.8/0/0.25 land on the
element and survive an item change, a muted item stays muted through a volume
command, and three cached assets survive an empty push.

Found by driving the real server and a real browser, not by reading. Each fix has a
test that fails without it.
1. A missing upload answered 200 with the DASHBOARD. express.static falls through on a
miss and the SPA catch-all caught it, so GET /uploads/content/<gone>.mp4 returned
15KB of index.html as text/html — under the `immutable, max-age=30d` header the mount
sets before it knows the file exists. Every player downloader treats 200 as success,
so a panel stores the HTML page AS the video and caches it for a month, rendering a
black frame with nothing in any log. Reachable exactly when it hurts: a content
replace writes a new random filename and unlinks the old one. The mount now
terminates a miss with a 404 and drops the cache header.
2. Four dashboard->device socket handlers had no capability gate. dashboard:device-command
has always refused a command the panel cannot honour, and the comment above it is right
about why ("hiding the button is not enforcement — this socket is reachable directly").
Every word applied to the four handlers immediately above it, which had none: a display
declaring [] still received screenshot-request, remote-touch, remote-key and
remote-start. Measured, not inferred. They now refuse on remote.screenshot /
remote.input / remote.stream and name the capability in the ack; remote-stop stays
ungated for the same reason set_debug does. The undeclared fleet is unaffected — an
absent declaration still resolves to its platform baseline and keeps everything.
The wall panel list (#235) made this visible: it offered a Screenshot button for every
panel, including a BrightSign, which has no screenshot capability at all, and popped a
toast promising an image that was never coming. GET /api/devices now ships the RESOLVED
capability array rather than the raw column ('[]' as a STRING, which Array.isArray reads
as "pre-capability server, show everything" — wrong in the one case that matters), so
the wall list and the fleet cards can hide what a panel cannot do. The remote pad's
Scrn Off / Scrn On were gated on remote.input while the Info tab gated the same two
commands on display.power; both now agree.
3. A register with no `platform` ERASED the stored one. captureIdentity coerces a missing
field to the literal 'unknown' and persistIdentity wrote it straight over. That column
is load-bearing: platformFamily() reads it, so one reconnect from an older build turned
a Tizen panel into a browser tab and handed it a volume slider the .wgt has no handler
for — the exact control BASELINE.tizen exists to hide — while a BrightSign lost screen
power and reboot and gained screenshots it cannot take. platform and client_type are
now preserved (physical facts); client_version and contract_version still decay, because
there "we no longer know" is the truthful answer. client_type 'wgt' is also read as a
second signal for a Tizen TV.
4. PUT /api/content/:id/replace carried its own shorter copy of the ingest logic. Replacing
a video left duration_sec at the OLD clip's length and nulled width/height, so #237's
brand-new "default an item to the clip's own length" then handed out the wrong number
for every later add — 32s scheduled for a 5s video is 27s of frozen frame. Replacing an
image measured it with raw sharp metadata and thumbnailed without .rotate(),
re-introducing the EXIF-orientation bug #172 had just fixed at ingest. Both paths now
share lib/content-ingest.deriveMediaMetadata.
Verified working and NOT changed: all six item-duration insert paths (a 31.7s clip stores
32 everywhere, an explicit value always wins, and no path can store a 0); the content
revision bump + filepath refresh reaching a real device socket; a landscape wall producing
byte-identical geometry to the pre-#236 expression; a portrait wall reaching the player as
side-by-side halves; cross-workspace isolation across 29 probes.
Full suite green (1319).

Both players carried calls that compile, read correctly, and are documented to
do something else. Verified line by line against docs.brightsign.biz and
Samsung's Smart TV Filesystem reference; every fix below cites the doc that
proves it, and the linter has been extended so each one fails here next time.
TIZEN
The offline media cache could never have worked on a panel. Its adapter used
the deprecated Filesystem API in three ways the IDL rules out:
`tizen.filesystem.resolve()` is declared `void`, so `var dir = resolve(...)`
was always undefined and MediaCache.create() returned null on every panel in
the fleet; `openStream()` is asynchronous, so appendPart read `written` before
any callback could run and returned 0 forever; and `moveTo()` is asynchronous,
belongs on the parent directory, and takes (origin, destination) — it was
called on a file handle with the arguments transposed. Rewritten against the
5.0 synchronous FileSystemManager, which is genuinely synchronous and is what
the decision layer needs. A Tizen 4.0 panel now reports available() false
instead of being handed a cache that silently writes nothing.
Writes are now POSITIONED rather than appended at EOF. Power cut between a
write and the index save — the exact event this feature exists for — replayed
the last chunk, and an append landed it twice: a silently corrupt video that
promoted as complete. A positioned write makes the replay idempotent.
Three decision-layer bugs alongside it: a 206 with no readable Content-Range
fell back to Content-Length, which is the CHUNK length, so the first megabyte
of a 50MB video promoted as a complete 1MB asset; a 200 whose body was short of
its own Content-Length returned 'done'; and a server with no ETag or
Last-Modified was re-fetched from zero on every sweep, forever, on precisely
the marginal link this feature exists to be gentle on.
The volume slider was dead. The dashboard sends `{level: 0..1}`; this handler
read `value`/`volume` as a 0..100 percentage, so it matched nothing and logged
"no usable value in payload" on every slider move while the panel declared
audio.volume as working. Both halves had to move together — taking `level` as a
percentage turns 50% into 0.5%, which is inaudible and looks like a fix.
Verified by driving the real handler in headless Chrome, before and after.
BRIGHTSIGN
FindMemberFunction is documented as available only when
roDeviceInfo.HasFeature("FindMemberFunction") is true. It was called
unguarded from the capability probe and from host telemetry — both on the event
loop — so a player without the feature would have died within a minute of boot
and taken the display with it. The guard needed guarding.
The boot report never arrived. The host flushed its buffer straight after
Show(), before the page had been fetched, while the player correctly waits for
its socket before subscribing. Between two correct decisions every boot line
fell on the floor. The host now waits for the page's `probe`, and the bridge
buffers until a consumer registers.
offline.cache was claimed on `navigator.serviceWorker` being present. It is
present on a BrightSign widget and will not run a worker — our XT245 passes the
check and never fetches sw.js. Now requires a controller, matching the web
player. Removed from the brightsign baseline for the same reason.
display.resolution was claimed on @brightsign/videooutput, which has no
setMode at all; mode setting lives on @brightsign/videomodeconfiguration.
roStorageHotplug.GetStorages() answers "USB1:/" while GetStorageStatus() is
documented as unreliable for "USBn:" — feeding one to the other re-created the
bug the static fallback list exists to avoid, and only on the OS versions that
have the enumerator.
dual/clone output mode put two full-screen widgets on output ONE, on top of
each other, while output two stayed dark: roHtmlWidget has no output selector,
and a second output is addressed by its display_x/display_y within the
SetScreenModes canvas. Now positioned properly, or refused with a reason.
Also: a manifest missing sha256/size passed `invalid` into typed parameters, a
runtime error at the call the comment already described and did not prevent;
storage_quota was a string where the docs say use a double; and the comment
crediting brightsign_js_objects_enabled with gating require("@brightsign/*")
named the wrong flag — it is nodejs_enabled.
TESTS
The two suites that mattered most were the ones that passed while the code was
broken, because they asserted on source text or against a fake more correct
than the platform. The host-diagnostics regexes now execute the bridge; the
media-cache suite now drives the shipped adapter against a fake tizen.filesystem
written from Samsung's IDL. Ten new rules in the BrightScript linter, each
verified to fail against the source it was written to reject.

The parity doc and the capability model had drifted from the players in both
directions, and nothing failed when they did. Auditing all four players against
their shipped sources turned up three controls a customer can press today that
change nothing, and a set of baselines that were partly too generous and partly
too stingy.
The three dead controls:
- The volume slider works on Android only. The dashboard sends set_volume as
{ level: 0..1 }; the web player reads payload.value and Tizen reads
payload.value ?? payload.volume, so on both the number is undefined and the
handler quietly declines. Three complete, working volume implementations
that cannot be driven. The fix is one line in each player and belongs to
those files; audio.volume is out of the web and brightsign baselines until
it lands, held there by a biconditional test that fails the moment a player
starts reading `level`.
- Every #161 Tier-2 command was refused for the entire fleet. lock_now,
power_menu, status_bar, block_uninstall and unblock_uninstall were gated on
system.device_owner, which no player declares and no baseline grants, so
supports() was false everywhere -- including on the device-owner panels the
feature was built for. The dashboard still drew the buttons because it also
gates on device.tier === 2. Fixed here: those five now accept
system.device_owner OR system.kiosk, which PlayerCapabilities.kt declares
under `if (isOwner)` and nothing else, and which no non-Android player
declares. Android should declare system.device_owner and retire the
stand-in.
- enable_system_capture required the capability it creates. It raises the
MediaProjection consent dialog -- the way a panel GAINS capture -- and was
gated on remote.screenshot, so the only panel that needs it was the one
panel that could not be sent it. Now ungated. The dashboard still hides the
button behind the same check; that half is a frontend change.
The baselines describe what an un-updated fielded display can do, and since
v1.9.29 is the first build in which any player declares anything, that means
v1.9.28. Every entry is now justified against `git show v1.9.28:<source>`:
- android loses display.power (v1.9.28 answers screen_on with a logged no-op,
so the ON half is dead on every fielded panel and one capability renders
both buttons) and system.reboot (owner-only; off-owner it paints an
accessibility power dialog over the signage). Scheduled reboots now skip
undeclared Android panels rather than logging a reboot that never happened,
which is the reason that gate exists.
- tizen gains display.power: v1.9.28 implements both halves with no signing
and no panel API, so withholding it hid a working control.
- brightsign loses audio.volume, display.power, system.reboot,
system.restart_player and offline.cache. All need a host bridge the unit is
not known to have, and restart_player without one is the page reload that
darkened a panel on 2026-07-28.
Also found, not fixed here because the files belong to others:
st-bridge.js computeCapabilities() is dead code -- nothing calls BS.capabilities()
-- and its 199 lines of passing tests constrain nothing a BrightSign actually
declares; the two disagree on six capabilities and the bridge is right about
most of them. BrightSign's "Force update" button is dead. PlayerCapabilities.kt
under-declares display.brightness.
The new test reads the player sources rather than the table: a dead-button rule
(every gated command has a branch somewhere), an unreachable-capability rule
(which would have caught system.device_owner), and biconditionals so a fix in a
player fails the test until the baseline follows. Claims that need hardware --
CEC reaching a display, a widget being allowed a service worker, SyncManager
holding frame lock -- are marked unverifiable in the document instead of
asserted.

#236: the wall canvas was secretly framebuffer space rather than the wall as
the audience sees it. Invisible while every panel is the normal way up, and
actively misleading the moment one isn't — two portrait-mounted panels standing
side by side had to be STACKED VERTICALLY in the editor, with a pre-rotated copy
of every video, before the output came out right. It worked, but only after
trial and error, and it meant a portrait wall could never reuse content as-is.
Each panel now carries a mounting rotation (0/90/180/270 clockwise, the same
convention as the per-device orientation setting), the canvas means the physical
wall, and the player works out the mapping. The geometry lives in one place,
server/lib/wall-geometry.js, because four players have to agree on it to the
pixel across a seam.
Existing walls need no migration and do not move. Every wall in the field is
rotation 0, and that case takes the original expression verbatim on all three
players rather than the algebraically-equal centre-based one — the two differ in
the last float bit, and a float's worth of disagreement between two panels is a
hairline seam down a wall that was aligned yesterday. Pinned by the first test
in wall-geometry.test.js and by wall-payload.test.js.
While a display is in a wall its panel rotation replaces its own orientation:
both describe the same physical fact, so honouring both turned the content twice.
#235: a wall replaced its members' cards, so one dead panel of a four-panel wall
was invisible from the dashboard, and inspecting a single screen meant pulling it
out of the live wall and putting it back. The wall screen now lists its panels
with live online state, a per-panel screenshot request, and a link to each
device's page; the dashboard wall card carries per-member status chips that track
socket updates.
Tests: wall-geometry.test.js re-simulates the CSS box independently and asserts
each panel's viewport maps onto exactly its own rect of wall space, for every
rotation, plus a mixed wall and the Tizen player's hand-ported copy executed
against the canonical rule. Full server suite green (1260).
Not verified here: the Android and Tizen renders on real hardware. Kotlin
compiles clean; the maths is shared/tested, the view plumbing is not.
#238: the dashboard preview of a 90/270 display was sideways while the panel on the
wall was right — the split that makes a preview useless, because a designer checking
portrait content can no longer tell a real fault from an artefact of the tool.
A portrait panel is a landscape framebuffer that the player rotates content INSIDE
(+90), hung turned the other way (-90); the two cancel and the viewer sees upright
portrait. The dashboard modelled only the first half. It iframed the player into a
box it had already given the finished 9/16 shape, so the player rotated a second time
inside a box that was pretending to be the finished picture, and nothing anywhere
stood in for the mount. Screenshots had the opposite half missing: they are the raw
framebuffer, shown untouched, so every portrait screen looked wrong on the cards and
in Now Playing too.
So each surface now has a stage (the panel's face) and a frame (its framebuffer),
with the frame turned by the INVERSE of the player's angle. Turning it the same way
is the tempting mistake and the worst kind of wrong: 90+90 lands upside-down, which
reads as nearly-right. The dimension swap is not cosmetic either — composing into the
real framebuffer shape is what makes the player lay content out in the same portrait
box the panel uses; hand it a portrait viewport instead and every zone and object-fit
decision is computed for a canvas no panel has.
The geometry is the players' own rule (server/lib/orientation-style.js), served to the
dashboard rather than re-derived, since a second copy of a rotation rule is exactly how
the two came to disagree. Covers the device preview modal, the playlist preview's
portrait toggle (same fault), Now Playing and the device cards. The Remote canvas stays
raw on purpose: taps are sent as fractions of it.

Adding a 32s video gave it the flat 10s default, so it was cut off mid-play
unless the operator looked up the runtime and typed it — per item, every time.
The content row already carries the probed duration; it now becomes the default.
The rule lives in one place (lib/item-duration.js) because the operator sees one
product, not six insert paths: playlist add, assign-to-display, group assign,
agency portal, content-only schedule, and the public API all share it. Only the
playlist route defaulted before, and it stored the raw probe (31.7) which the
Android player's optInt read silently truncated back to 31.
Explicit values always win. Content with no trustworthy duration (image, widget,
YouTube, remote URL, failed probe) keeps the 10s default, and a duration that is
0/negative/NaN or absurd (> 12h, i.e. a broken probe) falls back rather than
reaching a device — a 0 makes the players schedule a 0ms advance, which self-loops
and black-screens the TV.
Dashboard: the add-item picker shows a clip's length, the assign-to-display modal
pre-fills the duration field from the selected clip (never overwriting a value the
operator typed), and onboarding stops hardcoding 10 on the first assignment.

The preview shipped without the skip control #104 asked for, so checking a late item meant
watching every item before it in real time — the thing operators do most when ordering a
playlist with a client on the phone.
The preview is already the real player in device-free mode (an iframe of /player?preview=1),
so this drives that instance rather than growing a second playback implementation: the
dashboard posts next/prev to the one contentWindow, the player steps its own currentIndex and
re-renders through the same path a natural advance uses, and posts back index/total so the
modal can say "3 of 7".
Nothing here can reach a live screen. A real display is driven over its server socket and holds
no window handle this page could address; the message listener is installed only by the preview
boot path, previewNavigate refuses outside PREVIEW_MODE, and both ends pin the origin.
Stepping is schedule-aware in the direction of travel — falling forward past a dayparted item
would make "previous" walk forwards — and a multi-zone playlist reports itself as such, because
all zones play at once and a counter there would be a lie.

ghcr refused the 1.9.29 push with "denied: permission_denied: Error from
intermediary with HTTP status code 403", then accepted the identical build on a
manual re-run minutes later. Nothing about the token, the permissions or the
workflow changed in between; the registry simply said no once.
The timing is what makes it worth handling. The GitHub Release job has already
published by the time this runs, so a failure here leaves a tag that exists with
no image behind it — alpha and every self-hoster pulling :latest see a version
that is announced and unpullable, which reads as a broken release rather than a
hiccup at a registry. It also needs a human to notice and re-run, which is the
part that does not scale.
One retry, after a pause, and a second refusal still fails the release.

Found deploying 1.9.29 to production. A worker's scope defaults to its own
directory, so /player/sw.js could only control /player/ and below; the fix was to
request a wider scope and permit it with Service-Worker-Allowed. That works right
up until something between the origin and the browser does not pass the header
on. Cloudflare served a CACHED response for that path across the deploy —
headers and all — and the registration failed outright.
A rejected registration is worse than a narrow one: the player runs with no
worker at all, on every URL, and nothing about it is visible from the server. The
origin was sending the header correctly the whole time; a cache-busted request
proved it. It self-heals when the edge entry expires, which is precisely the kind
of fix nobody should have to know about.
Served from /, the default scope is already the whole origin and no header has to
survive the trip — through Cloudflare, through whatever a self-hoster puts in
front of it, or through a corporate proxy we will never see. /player/sw.js keeps
serving for players still asking for it, and the header is still sent where it
does survive.
Verified in a real browser: all three of /player, /player/ and /player/index.html
are controlled from root scope.

A BrightSign could see things the page cannot ask for — the uptime, the wired IP,
the video mode in force, which volume it booted from, whether a staged package
applied — and it printed all of it to a serial console. On a panel on a wall that
is the same as reporting nothing.
The cost was concrete and recent. A single bad string literal stopped the host
script compiling; the only evidence anywhere was one line on a cable, and from
the server the display looked identical to one that had never started. Diagnosing
it needed someone physically present with a serial adapter. Every other player
reports its own failures.
Three hops, each thin: the host posts, the bridge carries, the player emits on
the channels it already uses (device:log, device:event, and the telemetry the
heartbeat has carried for releases).
The pre-widget phase is the part that matters and the part that was hardest to
reach — the storage probe, a pending package being applied, the video mode being
set, all happen before there is a page to talk to. Those lines accumulate in a
buffer and flush the moment the widget exists, so the boot story arrives even
though it happened before anyone could listen. BrightScript has no global store
here (no GetGlobalAA), so the buffer is threaded explicitly; losing the boot
entirely was the worse option.
Two things become incidents rather than console lines: the watchdog rebuilding a
wedged widget, which is the most important thing a player does unattended and
previously healed in silence — a panel rebuilding itself every two minutes looked
exactly like a healthy one — and a load-error, which now names the resource that
failed. Both use event types the server actually accepts; an invented one is
dropped silently and would have been just as invisible.
Host telemetry merges into the existing snapshot rather than opening a channel,
and the host's numbers win where they overlap: navigator.storage.estimate()
describes the widget's cache quota, not the disk, so a panel can report gigabytes
free while the volume holding them is full.
Two API traps caught in my own new code before it shipped, both the same shape as
the ones being fixed: Str() applied to a value already documented as a String
(it is for numbers, and would abort the event loop while reporting a diagnostic),
and Stri() handed a float from an inline division. The checker now pins the first.
Verified on the XT245: boots clean, plays, online. The bridge and player halves
are served BY the server, so they take effect on the next deploy.
