There is no way to answer "how many screens run ScreenTinker?". The product is
self-hostable by design, so most installs are invisible to us on purpose — and
should stay that way. This asks once, and reports only if the operator says yes.
The entire payload is three fields:
{ instance_id, version, screen_count }
instance_id is a random UUID minted on first use and kept in app_settings. It
carries nothing about the install; its only job is to let two reports from the
same server be recognised as one server, so a count is a count rather than a sum
of duplicates. That makes a report pseudonymous rather than anonymous, and the
wording shown to operators says so rather than claiming otherwise.
The payload is short on purpose. Every field added costs participation, and
participation is the only thing that makes the resulting number worth quoting.
Player-platform counts were considered and left out: release assets are already
published per platform, so GitHub's per-asset download counts answer "where should
effort go" at zero privacy cost and without asking anyone for anything.
Verifiability is the feature, not the copy. Settings shows the ACTUAL payload this
server would send, generated live from its own data, plus what it last really sent
and when. The payload is built in one function so a reviewer can check it at a
glance, and the test fails if a field is ever added.
Both answers persist. Declining is remembered as 'off' rather than falling back to
'unasked', so the prompt cannot return after an update — re-prompting is how
telemetry earns its reputation and gets patched out.
Collector side is inert unless TELEMETRY_COLLECTOR=1, so a normal install never
exposes the endpoint. Reports upsert on instance_id rather than appending, so an
install reporting daily occupies one row rather than 365 a year. The source IP is
never read or stored — receiving one is unavoidable, logging it would quietly turn
a pseudonymous report into an identifiable one.
Tests pin the negative promises, which are the ones that rot silently: sends
nothing before consent, sends nothing after a decline, payload is exactly three
keys, id survives a restart, a failed send never records a phantom report. Screen
count excludes unpaired provisioning rows, which would otherwise overstate the one
number this exists to state honestly.
docs/telemetry.md documents the payload, what is not sent, how to verify it, and
that any published total is a floor rather than a basis for extrapolation.
1657/1657 pass.
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).

#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.

Every device control was offered to every display. A browser tab was shown
"Reboot device", a Tizen TV was shown screen power, a player with no
framebuffer read was shown a live view that stayed black. They all looked
like working buttons and did nothing — the "reports success and changes
nothing" shape that keeps costing people days.
Players now declare what they can do at registration, because only the
player knows at runtime: an Android panel gains real screenshots when
accessibility is switched on and loses Tier-2 when device owner is revoked.
The dashboard hides what is not supported rather than disabling it, and the
Info tab lists the capability set so a missing control is explainable.
The declaration is three-state and the middle state is load bearing: NULL
means "has never told us anything" and falls back to a per-platform
baseline, because several hundred displays in the field will not update
before this deploys and blanking their controls would be a far worse bug.
An empty array means "I genuinely can do nothing" and is honoured.
Hiding a button is not enforcement, so unsupported commands are also
refused server-side — the socket is reachable directly and a stale tab
still renders the old controls. Group sends report skipped devices
separately from sent ones; counting an unreachable member as "sent" is how
an operator walks away believing the whole group rebooted.

st-sync.js wrapped SyncManager but nothing drove it. The player now does: the
leader opens a new sync session on each advance, and every member — the leader
included — binds the video with attachVideo() on a NEW id only.
The leader binds from its own broadcast rather than at announce() time on
purpose. Starting when it announces would put it ahead of its followers by the
width of the network, which is the one desync nobody would think to look for
because the leader always looks correct.
Item selection stays clock-derived under both backends. Native sync replaces
only the seek/nudge drift correction, because setSyncParams has the element hold
its own alignment and correcting it ourselves would fight the platform — every
frame we moved is one it then has to undo. Keeping selection on the shared clock
is also what keeps images and widgets, which have no setSyncParams, advancing
with the videos instead of drifting off alone.
LEADER RULE: reuse the existing election (resolveGroupLeader) rather than adding
a column. It already resolves pinned-if-online, else first online member on the
shared playlist, else first by id — deterministic, stable, and already what the
group-sync payload reports. A second mechanism could only disagree with it.
Added on top: a group whose elected leader is OFFLINE falls back to our
protocol. Ours is leaderless and carries on; native sync has exactly one
broadcaster, so those members would sit waiting for an announcement that never
comes, with the dashboard showing a healthy group throughout.
device_groups.sync_backend ('auto'|'screentinker'|'brightsign') is the operator's
REQUEST; the answer comes from the existing pure resolveSyncBackend() so the
players, the dashboard and the stored setting cannot disagree. The resolved
backend, reason and downgraded flag ride in the group_sync payload and in the
group API, and the dashboard shows the refusal reason instead of a setting that
quietly isn't in force. An unrecognised value is rejected rather than stored,
because the resolver reads anything unknown as 'auto' — a typo would otherwise
return 200 and run a different protocol than the UI displayed.
FIXED WHILE HERE: the player re-entered group sync only when the group ID
changed, with a comment noting the clock protocol has no leader role. Native
sync has one, and neither a protocol switch nor leadership moving alters the
group id — so a player promoted to leader kept behaving as a follower, nobody
announced, and the group sat unsynchronised. The re-enter key now includes the
backend and the leader flag.
971 pass (+17).

Reported by a customer with two screens and two groups: dragging a screen from one group
to the other showed a confirmation, changed what the screen was playing, but left the
displays page showing the old group — and a second attempt said it was already in group 2.
All three observations were correct. The drop handler borrowed the Manage modal's
"add it to X too?" confirm, then called addDeviceToGroup and nothing else, then reported
"Moved {name} to {group}". So it asked about adding, claimed to move, and added: the
screen ended up in BOTH groups. The page was not stale, it was accurate — and the retry
was right too, because by then it really was in group 2 as well as group 1.
The screen's content DID change because joining a group syncs the device's playlist to
the group's, which is why it looked half-applied rather than broken.
Drag is a move gesture, so it now removes the other memberships after adding the new one
— add first, so a failure leaves the screen in the group it already had rather than
ungrouped by a half-finished move. A removal that fails warns rather than reporting
success it did not achieve.
The Manage modal is deliberately left alone: its checkboxes are add/remove and its "too?"
wording is accurate there. Multi-group membership is a real feature; it just is not what
dragging means.
Not merely cosmetic: deviceSyncGroup() notes it picks "deterministically if it's somehow
in several", so a screen left in two sync-enabled groups gets an arbitrary one. A
half-completed move leaves synchronised playback ambiguous.
Strings added to the six locales that carry the dashboard set; hi.js has none of them and
falls back to English.
A title= is a tooltip the user reads and an aria-label is what a screen reader
says, but fourteen of them were hardcoded English. They were invisible to the
key checks added earlier precisely because they never call t() — so a French
user hovering the only route to workspace members read "Manage members", and a
German screen reader announced every modal's close button as "Close".
The user-visible ones matter most: the workspace switcher's Manage members and
Rename, the video wall's rename and remove, and the dashboard's select-for-wall.
All are translated into every active locale, along with the close buttons.
A test now rejects a capitalised literal in a title or aria-label, since that is
the shape this takes and nothing else catches it.

A user reported not knowing how to get content onto a screen. There was already
onboarding — a modal wizard — but it is gated on a localStorage flag: skip it
once and it never comes back, and it never knew whether you succeeded at
anything. Someone who closed it was left with no thread to pull, which is
exactly what was described.
A second tour would repeat that mistake. Tours are dismissed and forgotten, and
they describe the product rather than the account. This is a checklist on the
dashboard that reads real state, so it cannot claim you have done something you
have not, it is still there tomorrow, and it names the one thing to do next
rather than everything the product can do.
The steps are the shortest true path to a screen showing something: connect a
screen, add content, put it in a playlist, send it to the screen. Only the last
one cannot be satisfied by creating an object and walking away — a screen has to
actually be pointed at something — so an account full of playlists with nothing
playing is correctly reported as unfinished, which is the failure that was
reported. Steps stay in dependency order, so nobody is sent to a page they
cannot use yet.
It disappears on its own once the first screen is live and can be hidden before
then, so it never nags someone who already knows the product. Once hidden or
finished it costs no extra request at all.

* feat(group-sync): synchronized playback per group (server + Android) [stage 1]
Play a group's shared playlist in lockstep across its displays — start/end items
together — by reusing the video-wall sync primitive with the spatial transform
removed and keyed on group_id instead of wall_id.
Server:
- device_groups += sync_enabled + leader_device_id (optional pin).
- buildPlaylistPayload emits a group_sync:{group_id, is_leader} block ONLY for a
member whose playlist matches the group's shared playlist (playlist-match guard —
a mismatched member is ignored, never synced). Membership via device_group_members.
- Leader auto-election: pinned-if-online -> first online matching member -> stable
fallback; computed (never persisted, so the operator's pin is preserved).
- group:sync / group:sync-request relay among eligible members (mirrors wall:sync,
guarded on membership + playlist match).
- Self-heal: re-push payloads to group members on (re)connect so is_leader refreshes.
- PUT /api/device-groups/:id accepts sync_enabled + leader_device_id and re-pushes.
Android:
- WallController is now mode-aware. WALL = transform + object-fit:fill + forced
follower-mute (UNCHANGED — every wall branch is byte-equivalent when isGroup=false).
GROUP = same leader/follower timing incl. the full video drift controller, but
full-screen (no transform), normal fit, and per-item mute honored (no forced mute).
- WebSocketService: emitGroupSync/emitGroupSyncRequest + onGroupSync/onGroupSyncRequest.
- MainActivity: dispatch emit by mode, parseGroupConfig, onPlaylistUpdate group hook.
Wall path is provably unchanged (additive mode, defaults to WALL). Kotlin compiles;
server suite 407/407.
Stage 2 (follow-up): web + Tizen parity, dashboard sync toggle + leader picker,
offline-sweep leader promotion.

* feat(group-sync): web + Tizen player parity [stage 2]
Mirror the Android group-sync generalization in the two web-based players so a group
with a shared playlist syncs across mixed player types, not just Android.
Web player (server/player/index.html):
- group:sync / group:sync-request handlers (index jump + latency-compensated video
drift, same maths as wall:sync) — no audio policy here, per-item mute honored.
- emitGroupSync() + applyGroupSync() (4Hz leader broadcast; follower sync-request).
NO CSS transform, NO forced mute (unlike applyWallMode).
- isFollower now also true for a group follower (suppresses self-advance).
- handlePlaylistUpdate handles data.group_sync (mutually exclusive with wall).
Tizen (tizen/js/player.js WallController + app.js):
- WallController is mode-aware: WALL styles the slice + forced follower semantics
(UNCHANGED when mode !== 'group'); GROUP clears any wall styling (full-screen) and
drives leader/follower timing only. syncId()/clearStageStyle() helpers; emitSync/
onSync/onSyncRequest key the event + id off the mode.
- app.js: group:sync/request socket handlers; onPlaylist enters group sync on a
group_sync block, else exits — content renders through the normal single-zone path.
Realigned the v4-exit-signal-phase3 TIZEN slice (682->696) shifted by the app.js edits.
Wall path is provably unchanged in both (additive group mode). Server suite 407/407;
both players' JS parse.

* feat(group-sync): dashboard UI — sync toggle + leader picker [stage 3]
On each group's header row:
- "Sync" checkbox -> PUT /api/groups/:id { sync_enabled } enables synchronized
playback; server re-pushes to members so they enter/exit sync mode. A hint notes
it needs a group playlist and that a display on a different playlist is ignored.
- When on, a "Leader: Auto / <display>" picker -> { leader_device_id } (null = auto-
elect, which self-heals; or pin a specific member to always lead when online).
Adds api.updateGroup(id, data) and the en i18n strings (en-only, mirroring the
existing per-group UI keys; the i18n parity test is apitoken-scoped).
Frontend parses (ESM); server suite 407/407.

* feat(group-sync): rework to clock/schedule sync + double-buffer + polish
Replace the leader/follower relay model with clock/schedule sync. Every
same-playlist member derives the identical (index, position) locally from a
server-disciplined clock + the deterministic playlist schedule, so sync:
- needs no server at play-time (offline-native), and
- has no leader role to double-elect (kills the split-brain class the leaked
WallController tick produced).
Server
- heartbeat-ack now carries server_ms + echoes client_ms for NTP-style clock
discipline; the client caches the offset (survives an outage).
- POST /groups/:id/resync -> group:resync (manual "Resync now").
- (kept: group_sync payload; leader machinery is now vestigial/ignored.)
Clients (web / Tizen / Android)
- Clock offset disciplined over the heartbeat, cached (localStorage / prefs).
- Schedule engine: pos = (syncedNow mod Sum(duration_sec)) with a CANONICAL
slot formula identical across platforms so mixed-platform groups can't drift.
- Snap-on-load: a fresh clip hard-seeks ONCE to the exact position (was ~5s of
gentle nudge to eat a ~0.3s load offset); steady-state keeps the gentle nudge.
- Double buffer: warm the next clip a few s before the boundary -> instant
switch, no black hold. Android pre-decodes on a throwaway surface so the swap
doesn't flash one wrong-aspect (landscape-stretched) frame.
- In-place duration edits: duration_sec dropped from the change signature and
applied in place, so a duration edit re-anchors the schedule WITHOUT a restart.
- Live-log shows discrete corrections (jump/align/seek) immediately; only the
steady-state line is throttled.
Android
- Fix leaked WallController leader tick: onDestroy() now stops it (Handler on the
main looper outlived the Activity -> zombie broadcaster / split-brain).
Dashboard
- Group leader picker -> "Resync now" button.
Tests: heartbeat-ack clock fields + resync route; exit-signal .wgt slice realigned.

Surface the server's manner-of-death (crashed / clean_exit / silent) as a subordinate qualifier ON the
Offline badge (not a 4th liveness state), on both the device list and device-detail. Rides livenessBadge.
- Reliability-aware label (contract §10): clean_exit reads plainly on /player (reliable), "(best-effort)"
on APK/.wgt. silent = "silent (no signal)".
- Honest hover tooltip on every reason (both views), incl. silent = "external/violent: power loss, network,
force-stop, or MDM/kill". Never fabricates a reason (no-reason -> plain Offline); state-gated (reason only
on Offline); clears on re-online (matches the server).
- Filter drill-in: <optgroup> "Offline by reason" -> Offline · silent / crashed / clean exit, matched via a
data-offline-reason attribute (Offline·silent = the MDM-killed set — the Bold use case). Existing
three-state filter (All/Healthy/Reconnecting/Offline) unchanged.
- List label shortened to fit the pill (full text stays on detail; tooltip carries the full honesty both).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Two follow-ups from the alpha diagnosis:
- FIX A (regression): filterDevices() compared badge TEXT to the option values 'online'/'offline', but
the badge text is now "Healthy"/"Reconnecting"/"Offline" — so selecting a status filter matched
nothing and emptied the dashboard. Now compares the liveness STATE via a data-liveness attribute, and
the filter is upgraded to All / Healthy / Reconnecting / Offline (an admin can filter TO reconnecting
devices — the point of the Degraded distinction).
- FIX B (legibility): the list rendered liveness as a status-dot where healthy=green/offline=red were
visually identical to the old indicator, so it didn't read as new. The list now renders the same
device-status-badge PILL as device-detail (3 distinct colors; amber Reconnecting visible on the list),
scoped with an is-liveness modifier so video-wall cards keep their dark "NxN wall" pill.
Frontend-only. 14/14 filter+render tests; full ES-module parse clean.

The patch4 server derives 3-state liveness (healthy / degraded-reconnecting / offline) and emits it as
data.liveness on dashboard:device-status, but the frontend only consumed binary online/offline — the
signal was thrown away. Add a shared livenessBadge() helper (utils.js) consumed by both the dashboard
device list and the device-detail view (initial render + live statusHandler). Degrades to the binary
status when liveness is absent (old payload / plain reconnect+disconnect emits / DB device object) so
nothing renders blank; unknown/no-data -> offline default. CSS: healthy=green, degraded=amber+pulse
(reads as reconnecting), offline=red — reusing the existing --success/--warning/--danger tokens. Labels
in en.js (all locales fall back to en). Frontend-only; server derivation unchanged. 13/13 unit tests.

Follow-up to the cache/backoff loop fix (aa23cf0): make a device that can't
self-install visible to operators, and fix the signature-verify bug that kept the
whole #139 fix from engaging on the actual Fire OS target.
Dashboard surface (Phase 2):
- devices gains ota_status / ota_target_version / ota_attempts / ota_updated_at
via the idempotent ALTER TABLE ADD COLUMN migration (non-destructive,
default-backfilled, idempotent on re-run).
- The device reports ota_status (OtaThrottle.statusFor -> none | pending |
manual_update_required) in device_info; the server persists it on register
(the reconnect backstop). devices d.* already surfaces it to the dashboard.
- Dashboard shows a non-blocking amber badge when manual_update_required
("Update available (vX) - install failed N times, manual update required");
i18n key in en.js (non-en inherits via the en fallback). Server suite +1 test.
Event-driven status (Option B):
- New device:ota-status WS message, emitted on STATE TRANSITIONS only
(enter-backoff -> manual_update_required, clear -> none), so the badge updates
promptly without waiting for a reconnect and without per-poll/heartbeat chatter.
Server handler persists the same fields; an unknown/forged device_id is a safe
no-op. The register-path persist stays as the reconnect backstop.
Signature-verify fix (the critical piece):
verifyApkSignature read the downloaded APK's signer via
getPackageArchiveInfo(GET_SIGNING_CERTIFICATES).signingInfo, but that field is
null for ARCHIVE files on API 28/29 (populated only from API 30). On Fire OS 8
(Android 9 / API 28) - the actual deployment target - this returned 0 certs from
a correctly-signed APK, so every OTA was refused as "tampered," the cache was
deleted, and the full APK re-downloaded every check cycle. This was the real
cause of the #139 re-download loop, NOT a silent-install failure: the cache and
backoff added in this branch sit behind this verify gate and never engaged on
the target.
Fix: below API 30, read the archive's signer via the legacy GET_SIGNATURES +
.signatures (its v1/JAR cert, which IS populated on 28/29). Keep
GET_SIGNING_CERTIFICATES + signingInfo for API >= 30 and for the installed-app
read (which works on 28+). The archive's signer is still extracted and compared
to the installed app's signer; a mismatch or zero-cert APK is still rejected.
This reads the cert correctly on old APIs - it does not weaken verification.
Verified on emulators:
- API 28: verify now passes for a legit APK (was: 0 certs, refused). Full backoff
then engages - 8.5MB pulled once, cache-hit on retries, backoff after 3,
manual_update_required emitted once; clears on successful update.
- API 28 negative: a re-signed (different-key) APK is still refused on cert
MISMATCH - no hole opened.
- API 30: unchanged path still passes (no regression).
- server suite 173/173, OtaThrottleTest 7/7.

Two independent multi-zone bugs, plus operator-facing warnings, i18n, and
regression tests guarding the data contracts.
Bug 1 — per-item mute was a no-op end to end:
- GET /api/devices/:id dropped the `muted` column from its assignments SELECT,
so the dashboard toggle never reflected state (the muted=false case in
particular). Column restored to the device payload.
- Android player now honours the per-item mute flag for YouTube (initial state
+ live via the IFrame JS API).
Bug 2 — items whose zone_id belongs to a different layout were silently dropped:
- Player fallback (web + Android): an orphaned zone_id is recovered into the
largest zone instead of vanishing, with telemetry.
- server/lib/zone-validate.js is the single source of truth for the orphan rule
(zone not in the device's active layout); used by the device payload
(per-item `orphan` flag + `active_layout_zones`) and the device list
(`orphan_count`).
- Assign-time hardening: a stale zone_id (not in the device's active layout) is
cleared to null on POST/PUT rather than persisted as a new orphan.
- scripts/find-orphan-zone-items.js: read-only sweep for existing orphans.
Dashboard warnings (operator-facing, never on the live player):
- Per-item badge + reassign affordance, device-list glance, preview banner.
- Graceful degradation: the zone selector falls back to /api/layouts/:id so it
can't vanish on a stale payload.
i18n: orphan-zone strings added to en/es/fr/de/pt/it (hi falls back by design;
count strings interpolate through tn()).
Tests: server/test/device-zone-contract.test.js adds 5 regression tests for the
data contracts above (muted true/false round-trip, active_layout_zones, orphan
flag + count, orphan-clears-on-reassign, assign-time clearing). 172/172 pass.

Option A: tile-on-tile (same section) reorders; tile-on-section / cross-
section stays group-assign (existing behavior untouched). Ordering is
cosmetic (dashboard only — nothing the device/player reads).
Backend:
- Migration: devices.sort_order column (idempotent ALTER; default 0).
- GET /api/devices ordering: sort_order ASC, created_at ASC (was created_at).
- POST /api/devices/reorder — ordered id array -> transactional
UPDATE sort_order=index, scoped WHERE workspace_id = caller's workspace
(forged cross-workspace ids are no-ops). Write-gated (viewer read-only).
Mirrors the playlist items reorder.
Frontend (the collision):
- Card-level dragover/drop: reorder ONLY when target is another card in the
SAME section; otherwise no-op so the event bubbles to the section's
group-assign handler. stopPropagation on the same-section drop prevents
the section handler also firing. Drop indicator (inset box-shadow).
Native HTML5 DnD; no library.
Validated (headless Chrome, synthetic DnD + a section-level drop spy):
- SAME-section reorder: section drop suppressed (sectionDrops=0), POST
/devices/reorder fires, NO group call, sort_order persists in DB.
- CROSS-section: section drop fires (sectionDrops=1), POST /groups/:id/
devices fires and membership actually changes — group-assign unbroken.
- The 0-vs-1 contrast proves stopPropagation disambiguates the shared gesture.
- 149 server tests green; migration applies clean on the prod-copy DB.

Wall editor: replaces the small grid with a Figma-style pan/zoom canvas. Each
display is a rectangle that can be dragged/resized to match its physical
arrangement; a separate semi-transparent player rect overlays the screens and
defines what content plays where. Drag empty space to pan, wheel to zoom,
"Center" button auto-fits content. Per-rect numeric x/y/w/h panel; arrow keys
nudge by 1px (10px with shift). Negative coordinates supported for screens
offset above/left of the origin. Coords rounded to integers on save.
Wall rendering: each device receives screen_rect + player_rect, maps the
player into its viewport with vw/vh and object-fit:fill so vertical position
of every source pixel is identical across devices that share viewport height.
Leader emits wall:sync at 4Hz with sent_at timestamp; followers apply
latency-adjusted target and use playbackRate ±3% for sub-300ms drift,
hard-seek for >300ms. Followers stay muted; leader unmutes via gesture with
AudioContext priming and pause+play retry to bypass Firefox autoplay.
"Tap to enable audio" overlay as a final fallback.
Reconnect handling: server re-evaluates leader on device:register so the
top-left tile reclaims leadership when it returns. Followers emit
wall:sync-request on entering wall mode (incl. reconnect) so they snap to
position immediately instead of drifting until the next periodic tick.
Group dissolve: removing a device from its last group clears its playlist
to mirror wall-leave semantics. Leaving a group with playlists on remaining
groups inherits the next group's playlist.
Dashboard: walls render as their own card section (hidden the device cards
they contain). Multi-select checkboxes on cards + "Create Video Wall" toolbar
action that creates the wall, removes devices from groups, and opens the
editor. dashboard:wall-changed broadcast triggers live re-render. Per-card
playback progress bar driven by play_start events forwarded from devices.
Security: PUT /walls/:id/devices verifies caller owns each device (or has
team-owner access via the widgets pattern), preventing cross-tenant device
takeover. wall:sync and wall:sync-request validate that the sending device
is a member of the named wall; relay re-stamps device_id with currentDeviceId
so clients can't spoof or shadow-exclude peers.
Schema: video_walls += player_x/y/width/height, playlist_id;
video_wall_devices += canvas_x/y/width/height. All idempotent migrations.

Session 1 of 2 of the i18n rollout.
- Split i18n module into per-language files under frontend/js/i18n/ so a
translator can edit one language without touching the others.
- Add Portuguese (pt) and seed Hindi (hi). Hindi is intentionally a skeleton
-- 0 keys, full English fallback -- because we have an active Indian user
and would rather ship "no Hindi" than ship machine-quality Hindi that
could read as unprofessional or get formality/gender register wrong.
- 183 keys, 100% parity across en/es/fr/de/pt; native review still
recommended before publicizing as "fully supported".
- Add t(key, vars) variable substitution and tn(keyBase, n, vars) plural
helper for _one/_other key pairs.
- setLanguage() now triggers a CustomEvent + HashChangeEvent so the
existing hash router naturally re-renders the current view, plus a
subscriber pattern for nav labels rendered once outside the router.
- Wire t() into 3 high-traffic views end-to-end: dashboard, login,
content-library. Sidebar nav labels in app.js update on language change.
- The remaining 16 views still ship with hardcoded English; they will be
wired in session 2. The t() lookup is robust against unwired views, so
the dashboard works in 5 languages while clicking into e.g. Schedule
still shows English. No regressions.

Device cards are now draggable. Group sections accept drops to add
membership (mirroring the Manage modal — same confirmation if the
device is already in another group). The Ungrouped section also
accepts drops to remove the device from every group it's in.
The existing Manage modal still works for bulk add/remove and for
finding devices not currently visible. Click-to-open on a card still
works; drag is only triggered on actual mouse movement.

Server-side: when a device reconnects on a fresh socket while the old
TCP zombie is still around, the old socket's eventual disconnect handler
flipped the device offline and removed the new heartbeat entry. Now we
proactively evict any prior socket on register and ignore disconnects
from sockets that are no longer the registered one for that device_id.
Frontend: dedupe devices by id from the API response and only render
each device in the first group it belongs to (multi-group membership
is still tracked for the Manage modal).

Phase 4 group scheduling: schema migration adds group_id to schedules with
CHECK constraint, scheduler evaluates group+device schedules with priority,
group deletion converts schedules to per-device copies. Dashboard gets
playlist assignment dropdown and current playlist label on group headers.
Player persists audio unlock state in localStorage so version reloads
don't lose audio on unattended displays.
