ScreenTinker f289609380 fix(auth): back break-glass recovery with a revocable, auditable grant
scripts/reset-admin.js mints a JWT carrying `recovery: true`, and middleware/auth.js
accepted that claim on its own with no database involvement. Three consequences:

- NOT REVOCABLE. The only way to invalidate an outstanding recovery token was to rotate
  JWT_SECRET, which logs out every user on the instance.
- NOT ENUMERABLE. Nobody could answer "is a recovery token outstanding right now?"
- NOT AUDITED. The synthetic id ('recovery-<nonce>') is not a users row, so every
  activity_log insert for it failed the user_id foreign key and was swallowed by a catch —
  a break-glass session left no trace at all.

A `recovery_grants` row per minted token turns all three around: DELETE revokes, SELECT
enumerates, expires_at bounds, and used_at + source_ip record when and from where it was
first exercised. The migration is additive and idempotent, so re-running is a no-op and a
code-only rollback just leaves an unused table.

The grant is session-scoped, NOT single-use-per-request. Recovery means many requests —
load the dashboard, list users, reset a password — so consuming the grant on the first
would make break-glass unusable, a worse outcome than the narrow replay window it closes.
Revocation and expiry are the controls; used_at is the audit stamp.

Also fixed, because it is the mechanism that hid this: logActivity now rewrites a
'recovery-*' id to a NULL user_id with the identity in `details`, so break-glass actions
are actually recorded instead of failing the FK; and a dropped audit row now logs a loud
[AUDIT-DROP] line naming the action and increments a counter, rather than vanishing into
console.error.

The token is written to a 0600 file instead of stdout — under systemd or Docker, printing
it meant journald captured a live admin credential well past its lifetime. Added --list
and --revoke-all.

In-flight recovery tokens minted before this change stop working; they live one hour and
were unrevocable, which is the problem being fixed. Minting already required a working DB,
so redeeming against one is not a new dependency.

test/session-token-resolution.test.js now mints a real grant for its recovery token, so
its assertions keep testing that break-glass is refused on those surfaces for lack of a
users row — not for the unrelated new reason that the token is invalid.

feat(content): subtitle/caption support as a content property (#223)
Subtitles/captions are set once in the content library and applied
automatically by the player — no in-player controls (the player stays bare).

- DB: 4 new content columns (captions_enabled, captions_lang for YouTube;
  subtitle_url, subtitle_lang for uploaded videos), all default off/NULL.
- buildSnapshotItems: denormalize the 4 fields into published_snapshot so the
  player receives them (enumerated query).
- content.js PUT: accept the 4 fields (subtitle_url only clearable here).
- POST /:id/subtitle: dedicated .vtt uploader (separate multer, since the main
  filter is video/image-only); stores the file in the content dir, records
  subtitle_url + subtitle_lang. Old subtitle file replaced; DELETE cleans up
  the sidecar.
- Player: YouTube -> loadModule('captions') + setOption(...languageCode) in
  onReady (best-effort, wrapped). Uploaded video -> a <track kind="subtitles">
  appended to the <video>, forced mode='showing' on load (same-origin, so
  CORS-clean like the video).
- Edit modal: YouTube gets an enable-captions checkbox + language; uploaded
  video gets a .vtt file picker + language + a remove-subtitle option. en/es.

Honest limitation (in the PR): YouTube caption control via the IFrame API is
undocumented/version-dependent and only works if the video actually has
captions — hence best-effort and wrapped so it can never break playback.

Test: content-subtitles.test.js — the 4 fields survive publish -> snapshot,
the .vtt upload endpoint stores + records the file, and a non-.vtt is rejected.
Suite 550/550.

Closes #216

feat(content): unstable-connection mode — cap YouTube at 720p for weak WiFi (#220)
On Android TV with weak/unstable WiFi, YouTube embeds auto-select 1080p+
and buffer/stall. Add a per-item "Unstable connection" flag that biases the
YouTube embed toward a 720p ceiling.

- DB: content.unstable_connection INTEGER NOT NULL DEFAULT 0 (non-destructive,
  existing rows unchanged).
- buildSnapshotItems: denormalize the flag into published_snapshot so it
  reaches the player (that query enumerates columns, so it had to be added
  explicitly — covered by a new test). preview-payload reuses the same query.
- content.js PUT: accept + coerce unstable_connection to 0/1.
- Player: playerVars.vq='hd720' + best-effort setPlaybackQuality('hd720') in
  onReady when the flag is set. Both are hints YouTube may still override, but
  together they bias the initial selection down to 720p.
- Edit modal: YouTube-only checkbox + hint; en/es i18n.

Scoped to the core ask; the issue's optional "Shorts get inverse hd1080"
refinement is intentionally left out (dubious for signage, and forcing higher
quality on a weak link is the opposite of the goal).

Closes #217

ScreenTinker b938fce368 feat(auth,tizen): TOTP 2FA UI, email verification on signup, Tizen SSSP install
Three features from this session, full server suite green (535/535).

TOTP 2FA (#100) — backend shipped without a UI; add it:
- Login: mfa_required -> 6-digit challenge (recovery codes accepted) -> /totp/verify.
- Settings > Account: enable (QR + confirm -> recovery codes once), regenerate,
  disable; SSO accounts see "managed by your identity provider".
- /totp/setup returns a server-rendered qr_data_url (bundled qrcode dep). keyuri
  folds the request Host into the issuer so multi-instance accounts are
  distinguishable in the authenticator app.

Email verification on signup — hosted HARD-block / self-host SOFT-nudge:
- email_verified column; existing users asked on first login (SSO + platform
  admins grandfathered); single-use 24h tokens (SHA-256 hashed).
- Gate engages only when email is configured (never locks out a no-mail instance).
  GET /verify-email + POST /resend-verification (generic, no account enumeration).
- Client: "confirm your email" flow + resend, verified/error toasts, self-host
  banner; onAuthSuccess refuses a tokenless response (defensive).

Tizen SSSP URL-Launcher install — Fusion-style one-URL native install:
- Server hosts /tizen/sssp_config.xml (dynamic <size>, always matches the served
  .wgt) + /tizen/ScreenTinker.wgt + a human landing. lib/wgt-cache.js resolves the
  signed .wgt (/data mount wins, mirroring the APK).
- build-wgt.sh also emits a static sssp_config.xml for CDN hosting.
- Retail panels require a Samsung Partner cert; dev-mode is SDB self-signed only.

fix(server): floor duration_sec to prevent widget zero-duration player loop (#199)
A duration_sec=0 assignment (especially a widget) made the player schedule a 0ms
auto-advance, self-looping and black-screening the TV. #198 fixed the Android
client; this hardens the source so a 0 can't be stored or served in the first
place. assignments.js accepted an explicit 0 on the POST/PUT/copy write paths —
the `= 10` destructure default only covers an ABSENT field, not an explicit 0.

- Add normalizeDuration() and apply it on all assignment write paths so any
  missing/invalid/<1 duration is floored to the 10s default.
- Add an idempotent migration repairing existing playlist_items rows with
  duration_sec IS NULL OR < 1 (fixes the live widget on existing DBs).

feat(diagnostics): device incident log — offline cause, network-vs-reboot, display-sleep (#175)
* feat(diagnostics): device incident log — why a screen went offline/black, with device-attested cause

Field request (Bold/s_t_r_o_b_e): "screens go offline randomly — let us see the cause." Answers it
across the fleet with a unified incident log, and — the key insight — lets the DEVICE disambiguate
the cause the server can't: if the app process survived the gap it was a NETWORK problem (not a
reboot), and it can even tell a dropped Wi-Fi/Ethernet link from a link-up-but-server-unreachable
(router/upstream) failure.

Schema:
- device_status_log gains reason + detail (WHY each offline transition happened).
- NEW device_events table (unified incident feed): type (offline/online/display_off/display_on/
  crash/reboot/network/app_error) + reason + detail, indexed, age-pruned + per-device capped.

Server:
- Capture the socket.io disconnect REASON (transport_close/ping_timeout/transport_error) instead of
  discarding it — recorded in the offline-cause log. devices.offline_reason stays on the EXIT-SIGNAL
  contract (crashed/clean_exit/silent) — a separate axis, preserved (violent death = 'silent').
- device:event handler (typed incidents) + device:connectivity-report handler (device-attested).
  lib/incident-classify.js (pure, unit-tested) composes reason+detail: cold_start->reboot;
  link_lost->network "Wi-Fi/Ethernet link lost"; else network "LAN up, server unreachable
  (router/upstream)"; appends SSID / weak-signal (rssi<-75) / IP-changed. On a report it upgrades the
  most-recent offline row from the server's guess to the device's ground truth.
- heartbeat timeout -> 'heartbeat_timeout'; retention/cap for device_events.
- Device-detail API returns statusLog.reason/detail + the last 50 device_events.

Device (Android WebSocketService): ConnectivityManager default-network callback (link-lost during a
gap) + Wi-Fi SSID/RSSI + IP snapshot -> device:connectivity-report on reconnect (app survived =>
network); ACTION_SCREEN_ON/OFF receiver -> device:event display_on/off ("screen went black"). All
guarded/feature-detected; no manifest change; compiles clean.

Web + Tizen players: reconnect connectivity-report (link_lost from navigator.onLine during the gap)
+ visibilitychange -> display_off/on. Best-effort (no wifi detail in a browser). Tizen exit-signal
marker slice untouched.

CMS (device-detail): the offline cause on the uptime-timeline hover + a new "Recent incidents" panel
(merged offline periods + typed events, friendly labels, detail, relative time + down-duration).

Built as a 4-way parallel agent fan-out over disjoint domains against a locked contract, then
integrated. Verified: full server suite 443/443 (incl. the seam fix keeping the exit-signal contract
intact), Android compileDebugKotlin clean, all players + CMS node -c clean.

* feat(diagnostics): internet-reachability probe — split "our server down" from "no internet" (#170)

Follow-up to the incident log: when a device's link is UP but it's offline, "router/upstream" was a
catch-all. The device now probes a public host (1.1.1.1 / 8.8.8.8 :443) DURING the gap, so the cause
pinpoints blame:
  - link_lost=true                     -> Wi‑Fi/Ethernet link lost (device's own link)
  - link up, internet_ok=true          -> server_down: internet reachable, OUR server was unreachable
  - link up, internet_ok=false         -> no_internet: router/ISP down
  - link up, no probe result           -> generic router/upstream (unchanged fallback)

- Android WebSocketService: fire a short daemon-thread TCP probe (443, either host) at disconnect;
  the result rides the connectivity-report as internet_ok (omitted if the gap ends before it finishes).
- lib/incident-classify.js: 3-way split on internet_ok; new reasons server_down / no_internet.
- Frontend i18n: device.event.server_down / .no_internet labels.
- Tests: +3 classify cases (server_down, no_internet, link_lost wins over internet_ok). 12/12.

Verified: classify 12/12, Android compileDebugKotlin clean, node -c clean. Refs #170.

* feat(diagnostics): log an 'upgrade' incident (old → new app_version) — server-side (#170)

When a device reports an app_version different from the stored one, applyDeviceInfo logs an
'upgrade' device_events row (detail 'old → new'). Server-side, so it covers Android/Tizen/web with
no client change; a fresh pair (no prior version) isn't counted. Adds device.event.upgrade label.

feat(agency): per-token upload folder — auto-created, subtree-confined (#158) (#171)
Agency-portal uploads previously all landed at the workspace library root, unsorted.
Instead of the issue's whole-workspace folder dropdown (which would leak every folder
name to an external party), bind ONE folder per agency token — admin-controlled and
agency-invisible — and scope the portal picker strictly to that folder's own subtree
(Hybrid-C). Fully backwards-compatible: no bound folder -> root, exactly as before.

Model / multi-workspace: an agency token is bound to ONE workspace at issuance, so the
token key IS that workspace's private link and the bound folder lives in that workspace.
An admin with N workspaces mints one token per workspace (each with its own auto-folder).
No workspace-switcher in the portal — the token is the tenant boundary.

Backend:
- api_tokens.upload_folder_id (additive; ON DELETE SET NULL -> deleting the folder falls
  back to root).
- lib/agency-targets.folderSubtree(): recursive-CTE helper = the SINGLE confinement source
  shared by GET /api/agency/folders AND the POST /api/agency/content target check, so the
  set the agency can SEE and the set it may WRITE to can never drift. Workspace-guarded at
  the anchor row; descendants inherit the workspace (folders.js forbids cross-ws parents).
- routes/agency.js: GET /folders (bound subtree only); POST /content defaults to the bound
  folder and 403s any folder_id outside the subtree.
- routes/tokens.js: create auto-creates "Agency — <name>" (or binds a picked folder,
  validated same-workspace, respecting the 100-folder cap) inside the token tx; new
  PUT /:id/upload-folder to rebind; listing surfaces the bound folder name.
- middleware/apiToken.js + lib/content-ingest.js: upload_folder_id onto req.apiToken; ingest
  writes folder_id.

Frontend:
- Agency portal: folder <select> shown only when a real subfolder choice exists (identifies
  the "Main folder" root client-side without learning the token's folder id).
- Settings: folder pick at token creation, bound-folder display, rebind modal.
- i18n: 7 new apitoken.* keys across all 5 locales.

Tests (429/429):
- test/agency-folder.test.js: 5 folderSubtree confinement bites (subtree in, siblings out,
  workspace guard, null -> root).
- test/agency.test.js (+1 e2e): auto-create, default-to-bound, in-subtree pick lands there,
  sibling -> 403, admin-pick, unknown-pick -> 400, rebind-to-root.

Closes #158.

feat(system-control): Tier 0/1 controls with no device-owner dependency (#160) (#169)
* feat(system-control): Tier 0/1 controls with no device-owner dependency [#160]

Track A of the system-control split (Track B = device owner, shipped in #168). Ships the
capabilities that need NO device owner, with graceful per-tier degradation.

Capability reporting (keystone):
- DeviceInfo now reports can_write_settings / accessibility_enabled / overlay_granted
  alongside the existing tier/device_owner flags; server persists them (3 additive device
  columns, older APKs default to 0); dashboard gates controls + shows what's grantable.

Android SystemControl (new, all best-effort / no-op when unsupported):
- Tier 0 (no permission): media volume (AudioManager STREAM_MUSIC), per-window brightness
  (WindowManager.LayoutParams.screenBrightness — dims our window only).
- Tier 1 (WRITE_SETTINGS): system-wide brightness + screen-off timeout (Settings.System).
- Commands set_volume / set_brightness / set_system_brightness / set_screen_timeout wired
  in MainActivity.onCommand; ALLOWED_COMMANDS extended for the group path.
- SetupActivity gains a one-time WRITE_SETTINGS grant row (mirrors the overlay/accessibility
  grants); manifest declares WRITE_SETTINGS.

Dashboard:
- device-detail "System control" section (any Android panel): volume + this-app brightness
  sliders always; system brightness + sleep-timeout only when the panel reports
  can_write_settings, else a "grant on the panel" hint. Sends on release (not drag).

Validated live on a non-owner tier-0 panel: dashboard → set_volume 0.75/0.15 → the panel's
STREAM_MUSIC volume moved to 11/2 (of 15). 423 server tests green.

Closes #160.

* fix(system-control): volume slider reflects real volume + device-owner brightness/timeout [#160]

Two fixes from live testing:

1. Volume "doesn't remember" — the slider hardcoded 50 because the panel never reported its
   current volume. Now DeviceInfo reports media_volume (0..1); a new lightweight device:info
   socket event lets the panel re-report right after a set_volume (no full re-register / playlist
   re-push); server stores devices.media_volume; the dashboard inits the slider from it.
   Validated: dashboard set_volume 0.60 -> panel STREAM_MUSIC 2->9 (of 15) -> stored 0.60.

2. System brightness/timeout on a DEVICE OWNER — was gated only on WRITE_SETTINGS, which an
   owner doesn't have. A device owner can set those via DevicePolicyManager.setSystemSetting
   with no grant, so SystemControl now takes that path when isDeviceOwner(), and the dashboard
   enables the Tier-1 controls when can_write_settings OR tier===2. STPolicy.setSystemSetting added.

deviceSocket device_info UPDATE extracted into applyDeviceInfo(), shared by device:register and
device:info. Migration: devices.media_volume REAL (additive). 423 server tests green.

* feat(system-control): brightness/timeout remember + move controls into a tab [#160]

Same "remember what it's set to" treatment as volume, now for brightness + sleep timeout, and
the System control section moves off the top into its own "Controls" tab.

Reporting (DeviceInfo -> device:info re-report -> devices columns -> dashboard slider init):
- system_brightness (read from Settings.System, no permission) + screen_off_timeout_ms.
- window_brightness: persisted in ServerConfig (survives relaunch, re-applied on MainActivity
  launch) so the per-window slider reflects it too.
- reportInfoNow() now also fires after set_brightness / set_screen_timeout.

Dashboard: new "Controls" tab (any Android panel) holding the volume/brightness/timeout controls;
every control inits from the reported value; sleep dropdown preselects the current timeout.

Server: +3 additive columns (system_brightness, window_brightness, screen_off_timeout_ms); the
device_info UPDATE stores them. Migrations all additive/re-runnable. 423 server tests green.

Validated live: set_brightness 0.40 -> stored window_brightness 0.40; volume 0.30 -> 0.33.

CI / Android unit tests (Kotlin schedule evaluator vectors) (push) Waiting to run
CI / Boot smoke + version check (push) Waiting to run
* 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.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* 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.

feat(ota): self-update kill switch — global, per-device, and MDM auto-detect (#166)
Lets an operator (or an MDM) own updates instead of the app self-installing, which
on managed panels shows a self-install confirm dialog over customer content
(#155). Three layered controls:

- GLOBAL (server): config.otaEnabled from OTA_ENABLED (default on). When off,
  /api/update/check returns update_available:false, reason:ota_disabled_global —
  the whole instance stops offering updates.
- PER-DEVICE (server + dashboard): new devices.ota_enabled column (default 1). When
  0, that device is never offered an update (reason:ota_disabled_device). A
  "Self-update (OTA)" toggle in the device settings flips it via PUT /api/devices/:id.
- AUTO-DETECT (Android): UpdateChecker stands down entirely when a foreign device
  owner (an MDM/DPC) manages the panel — detected via getActiveAdmins() + not being
  device owner ourselves. Pure client-side, errs safe, needs no server change.

The two server gates are enforced server-side so they cover EVERY client version,
not just ones with the client-side stand-down. When OTA is off the device still
reports its version (dashboard sees state); the MDM/operator owns the actual update.

For an MDM-managed fleet (e.g. Pivot/MAXHUB), turn OTA off and let the MDM push the
APK — the install-dialog race disappears from every angle.

Tests: +2 (per-device gate + a real OTA_ENABLED=false server for the global gate);
full server suite 393 pass; Android compiles.

ScreenTinker b72e964433 feat(dashboard): surface per-device settings PIN + backfill existing fleet (#152)
Some checks are pending
CI / Unit tests (node --test) (push) Waiting to run
CI / OpenAPI spec lint (push) Waiting to run
CI / Android unit tests (Kotlin schedule evaluator vectors) (push) Waiting to run
CI / Boot smoke + version check (push) Waiting to run
The server provisions a unique settings-menu PIN per device, but nothing surfaced
it — leaving the on-device hidden settings menu effectively unopenable. Show the
PIN on the device Info tab (native players only), with i18n across 6 locales.

Also backfill a unique 6-digit PIN for already-paired devices that predate the
settings_pin column, so the existing fleet isn't locked out (delivered on their
next reconnect via the existing device:paired re-send). Idempotent UPDATE.

ScreenTinker 8ad2258e7c feat: app-ending signal (exit-signal contract v1) — server + APK + .wgt + /player
Best-effort "last gasp" so Offline is annotated with WHY it went away — completing the liveness story.
Categories: crashed (client uncaught-exception), clean_exit (client confident lifecycle-end, best-effort),
silent (SERVER-inferred by absence — the honest catch-all for violent/external death incl. force-stop/MDM).

SERVER:
- device:exit socket handler + token-authed beacon POST /api/device/exit (reliable-on-unload). Both gated
  by liveness.sanitizeExitReason (honesty: only crashed/clean_exit accepted; 'silent'/unknown rejected).
- offline_reason/offline_reason_at/offline_detail columns (additive migration). Clear-on-online (a reason
  is always THIS session's); offline transition COALESCEs to 'silent'. Pure annotation — offline detection
  and #148/liveness are untouched. Offline dashboard emits carry offline_reason + client_type.
CLIENTS (canonical {reason,detail} shape):
- /player: window error/unhandledrejection + pagehide(persisted=false) -> sendBeacon.
- .wgt: same + BACK-key exit -> socket.emit + sendBeacon.
- APK: global UncaughtExceptionHandler -> crashed (blocking beacon, chains to default); Service.onDestroy
  -> clean_exit (socket + bounded beacon). New ExitSignal.kt. onStop/onPause NOT wired (background != exit).
Proven (Phase 3): per-category classification, nothing misclassified, external kill -> silent (never
clean_exit), backgrounding emits no false exit, #148/reconnect-vs-exit intact. 382/382 suite green.

ScreenTinker 4cf156d4a0 feat(server): v4 liveness CORE pass — uniform heartbeat-ack + ack-gap + dashboard liveness + identity
Server-side keystone: the server now honors the v4 liveness contract uniformly across the MIXED
fleet (v4 + old pre-v4 + disconnected), all three clients depending on it.
- UNIFORM heartbeat-ack: emitted from the single shared device:heartbeat handler (uniform by
  construction; no per-client/per-path branch), BEFORE the auth guard so a known device's watchdog
  stays armed. Harmless to old clients (they ignore it).
- RECONNECT-WINDOW ack-gap fix (ackableHeartbeat): ack a KNOWN device (authed socket OR a device_id
  that resolves) even mid-reconnect; NOT anonymous/never-authenticated sockets (degrade-safe);
  identity-agnostic. No state mutation before requireDeviceAuth (auth surface unchanged; device_ids
  are uuidv4).
- DASHBOARD LIVENESS (deriveLiveness): server-derived, VERSION-AGNOSTIC Healthy/Degraded/Offline
  from signals every client sends (socket presence, heartbeat age, reconnect frequency); no client
  status-push.
- IDENTITY CAPTURE (capture-don't-act): client_type/client_version/platform/contract_version columns;
  degrades to legacy/unknown for old clients; NEVER breaks register.
- A-BUCKET FIX (QA): recordReconnect + persistIdentity gated on !isPlaylistRefresh (a ~45-60s refresh
  is not a reconnect/new identity — matches #134), and the identity write is change-detected — closing
  the WAL write-amplification (A1) and the benign-refresh -> false-"Degraded" (A2) regressions.
New lib/liveness.js (pure helpers, unit-tested). 30 new tests (uniform ack, ack-gap, mixed fleet,
identity capture, cross-client conformance, refresh-gate reproduce-then-prove); 366/366 total.
OTA artifact-availability is a separate concern (out of scope).

ScreenTinker 099320af29 fix(db): WAL checkpointer worker-death handling (respawn + inline-autocheckpoint fallback)
Close the disk-fill trap: with wal_autocheckpoint=0 a dead worker means nothing checkpoints.
Controller now respawns an unexpectedly-dead worker (bounded: RespawnMax/RespawnWindowMs +
backoff); on exhaustion it re-arms a conservative inline autocheckpoint (FallbackPages) on the
main connection + reclaims the backlog, logging loudly. Clean stopWalCheckpointer() teardown is
distinguished via a 'stopping' flag so SIGTERM never triggers respawn. Env-gated worker
fault-injection (WAL_CKPT_FAIL_START) for tests. Local only — no bump/tag.

ScreenTinker 677b17028e feat(#146): billing:read scoped token — dual-path auth for the Usage Report (Option C)
Least-privilege way to read GET /api/billing/usage without requiring platform admin.
Additive + isolated: reuses the existing api_tokens scope system (the off-ladder 'agency'
scope is the precedent) and does NOT touch the shared role/permission checks other
endpoints rely on.

- New off-ladder scope 'billing:read' (routes/tokens.js SCOPES). Like 'agency' it is NOT
  on the read<write<full ladder, so tokenScopeGate rejects a billing token on every
  PUBLIC_ROUTER and JWT-only routers reject any st_ token -> the scope grants billing-read
  and NOTHING else.
- DUAL-PATH gate requireBillingRead (middleware/apiToken.js), written as an EXPLICIT OR:
  authorize if (billing:read token) OR (platform-admin session). Admins keep read access
  but are NOT required to; the token path doesn't lock out admins or vice versa. Billing
  route now mounted with bearerAuth (token OR JWT front door) + requireBillingRead (was
  requireAuth + requirePlatformAdmin).
- MINTING is platform-admin only (stricter than read/write/full/agency, which any
  workspace member may mint) since a billing:read token grants GLOBAL billing-read. Note:
  no finer "owner" tier exists here (#14 collapsed superadmin->platform_admin), so
  PLATFORM_ROLES is the top level required.

Tests (5, test/billing-authz.test.js): dual-path positive (token AND admin session both
200) + negative (user 403 / anon 401); scope isolation (billing token 403 on /api/devices,
401 on /api/admin; read token 200 on devices but 403 on billing); minting owner-only
(user + ordinary-admin 403, platform-admin 201); revocation -> 401. Existing token
firewall/partition suite (api.test.js) + billing-endpoint tests unchanged & green. Reused
the exact SHA-256 token-verification path (no bcrypt/new mechanism). Suite 306/306.

NOTE: spec described bcrypt + JSON `scopes` + an analytics:read precedent; this codebase
actually uses SHA-256 + a single `scope` TEXT column + 'agency' as the off-ladder
precedent. Implemented faithfully to the real system.

ScreenTinker 977407ce99 feat(#146): usage metering + admin-gated Billable Screens report (contract system-of-record)
Implements the ByteTinker-Bold distribution-agreement billing math and surfaces it on a
standalone admin-only route. No UI (the API figure is the deliverable). Server-side only.

Contract math (lib/billing.js, config-driven; defaults ARE the agreement):
- ASD (per device/day) = min(1.0, online_seconds / (hours*3600))   # 28800 default
- BillableScreens (per month) = round-half-up( Sum ASD / days_in_month )
- Flat tier (not marginal): 1-499 $1.50 / 500-999 $1.25 / 1000+ $1.00; cost = screens*rate.
Single global rate card for now (per-tenant is a future concern; noted in code).

Data foundation:
- New durable rollup device_usage_daily(device_id, day 'YYYY-MM-DD', online_seconds),
  index on day. status_log (3d) / telemetry (24h) can't back a billing month.
- Accumulated INCREMENTALLY off the heartbeat tick from the live connection map (same
  source as devices_connected) - never reconstructed from logs. Each tick credits every
  connected device's today-row (min(86400, +elapsed)), chunked + transactional (non-blocking);
  per-tick credit capped (accrualCapSeconds) as a stall/restart guard.
- Retention ~400d, pruned via chunked-prune (pruneUsageDaily in runMaintenance).

API: GET /api/billing/usage?month=YYYY-MM (default current), requirePlatformAdmin, mounted
SEPARATELY from /api/status (billing is revenue data + a heavier aggregate; must not touch
the hot status path). Reads the rollup only. MTD figure averages over COMPLETED days only
(today shown in `daily` but excluded until it completes); is_final + billable_screens_final
appear once the month completes.

Tests (12): ASD math; billable round-half-up; flat tier/cost boundaries; accumulator
(accrues by interval, caps at 86400/day, disconnected doesn't accrue); report MTD-excludes-
today + final-month is_final; retention prune; endpoint authz (admin 200 / non-admin 403 /
anon 401) + billing absent from /api/status. Suite 301/301. First-full-month caveat +
formula in docs/billing.md.

ScreenTinker 9418582de5 feat(#146): always-on devices_connected + admin-toggleable /api/status debug block
1. devices_connected (always on, never gated): a top-level /api/status field next to
   loop_lag = LIVE WS socket count from the heartbeat connection map (getConnectedCount),
   NOT devices.status='online' (which lags by the offline-timeout). The single
   most-glanced operational number, so it can't disappear when debug is off. Also dropped
   4 dead per-poll COUNT(*) queries the route computed but never returned.

2. debug block behind an admin flag: new minimal app_settings KV table (none existed;
   ai_settings is per-workspace, white_labels is branding) + lib/app-settings.js (cached,
   refresh-on-write so status polls read a cached boolean, not a DB row).
   routes/status.js includes `debug` ONLY when status_debug_enabled is on (persisted value
   overrides the STATUS_DEBUG_ENABLED env default); when off the key is omitted entirely.

3. Admin toggle: GET/PUT /api/admin/status-debug (requirePlatformAdmin, mirrors the
   branding endpoints) + a checkbox in the Admin tab "Status endpoint" section
   (mirrors the branding checkbox). Takes effect on the next poll, no restart.

Tests: devices_connected always present+numeric and rises with a live socket (booted +
socket.io-client); debug present by default, admin flips OFF -> key omitted (loop_lag +
devices_connected remain) -> ON again, no restart; non-admin 403, anon 401; unit coverage
for getConnectedCount + app-settings default/override. Suite 289/289.

ScreenTinker fa3ab44c20 feat(#146): /api/status.debug throughput counters (gauges -> gauges + work done)
The debug block exposed only gauges (buckets, quarantined, inFlight) — state, not work.
A real flapping Firestick reads as flap.buckets:36, quarantined:0, indistinguishable
from healthy. Add lightweight in-memory throughput counters (total + last-completed
rolling window) so the server tells the flapper/flood story itself.

- lib/rolling-counter.js: shared bounded scalar counter (total, curWindow, lastWindow,
  windowStart); rolls lazily on bump AND read (no timer), idle decays to 0.
  DEBUG_STATS_WINDOW_MS default 60000.
- flap-limiter: refused{Total,LastWindow} (every allow:false), quarantineStarts{Total,
  LastWindow} (a quarantine event stays visible after the gauge decays).
- ota-breaker: stats() rateBackoff{Total,LastWindow}.
- ota-download-guard: servedTotal/shedTotal alongside the per-window values.
- database: maintenance sweepsTotal (confirm the prune is firing, not stalled).
- routes/status: debug block gains ota_breaker + the new fields (aggregate-only, cheap).

Tests: rolling-counter window-roll + idle decay; each counter increments on the right
event; booted /api/status asserts the new fields present + numeric. Suite 285/285.
Fallout doc: observability section lists the fields + what each tells a soak-watcher.

  maintenance: {deleted, ms, at, running},   // last status-log prune
  log_coalescer_buffer,

Every new subsystem is disable-able via env (flip + restart, no redeploy/bisect):

- OTA_DOWNLOAD_GUARD_ENABLED=false -> download guard always admits.
- MAINTENANCE_BAND_GATE_ENABLED=false -> interval maintenance ignores band.

ScreenTinker 2f7133f8c8 fix(#146) A: non-blocking maintenance — chunked+yield+band-gate all sweeps
The death-spiral amplifier: pruneStatusLog ran a whole-table ROW_NUMBER() sort,
40-48s synchronous on the 1.1M-row incident table, freezing boot -> healthcheck
fail -> restart loop.

- lib/chunked-prune.js: shared chunkedDelete (rowid IN (SELECT ... LIMIT ?) since
  better-sqlite3 has no DELETE...LIMIT) — bounded batch + setImmediate yield between
  batches, optional band-gate. Core invariant: no sync op blocks >~50ms ever.
- pruneStatusLog: rewritten per-device via a loose index-scan seek
  (WHERE device_id > ? ORDER BY device_id LIMIT 1 — O(log n) each), retention +
  newest-cap trimmed in bounded batches, async, re-entrancy-guarded, band-gated on
  the interval / un-gated + fire-and-forget at startup so a bloated table self-heals
  on deploy WITHOUT freezing boot.
- heartbeat.js: maintenance moved off the interval body into async band-gated
  re-entrant runMaintenance(); play_logs + provisioning prunes chunked; offline-marking
  stays synchronous.
- pruneTelemetry: bounded single statement (OFFSET 6000 LIMIT batch), stays sync.
- idx_devices_provisioning so the provisioning prune batch subquery is an index range.

Tests: correctness (per-device cap + retention, independent devices), 300k-row backlog
trims in many batches with max event-loop gap <250ms, band-gate no-op while critical +
startup runs regardless, re-entrancy (concurrent -> once). Existing prune tests updated
to await. Suite 247/247.

ScreenTinker 81e7d58099 fix(#146): reconnect/heartbeat storm containment (beta5)
Second head of the OTA-loop root cause (#144), on the connection/heartbeat
layer: unbounded device-driven work with no circuit-breaker. Symptoms in Bold
prod — devices shown OFFLINE in CMS while online+playing, loop-lag simmer
(p99 300-1145ms), device_status_log grown to 1.1M rows.

False-offline (two causes, both fixed):
- evicted-socket re-arm race: evictPriorSocket runs before registerConnection,
  so the evicted old socket's disconnect armed a fresh offline timer for a
  just-reconnected device. Tag evicted socket ids and bail in the disconnect
  handler (ws/deviceSocket.js).
- heartbeat checker false-positive: a device with a live socket in /device is
  UP even if its in-memory lastHeartbeat is stale under lag; skip it instead of
  marking offline (services/heartbeat.js).

Storm containment:
- batched/coalescing device_status_log writer (lib/status-log-writer.js): net
  state per device per flush, breaking the storm->bloat->slow-write->lag loop.
- newest-N-per-device row-count cap in the global sweep (db/database.js): hard
  bound regardless of churn; trims the existing 1.1M backlog on the first sweep.
  Per-device prune unified to statusLogRetentionDays (was hardcoded 7d).
- reconnect-throttle idle-bucket sweep (lib/reconnect-throttle.js): the #142
  throttle already existed; added the memory-bound sweep it lacked (wired in
  server.js). No second breaker.
- cosmetic: cap the OTA breaker level counter (lib/ota-breaker.js).
- best-effort status-log flush on the crash path (server.js).

Tests: load harness (test/reconnect-storm-load.test.js) proves breaker engage,
clean offline-clear, no-throttle-on-normal-reconnect, batched writes, bounded
loop-lag; cause-1 re-arm race proven with teeth (test/evicted-socket-rearm.test.js).
Both mutation-checked (fail without their fix). Full suite 240/240.

ScreenTinker 404c3301dd fix(#143): enforceable device block + fix the null-token auth short-circuit
Highest-priority #143 item (operator finding from Bold): nulling a device's token
did NOT lock it out — device 75c2a08a immediately reconnected and saturated the
loop. Two distinct defects:

1. Auth short-circuit (the cause). device:register used
     if (device.device_token && !validateDeviceToken(...)) { reject }
   so a NULL/empty STORED token made the guard falsy -> validation SKIPPED, and the
   next block even MINTED a fresh token and persisted it. Nulling a token thus
   RE-PROVISIONED the device instead of locking it out. Fix: drop the
   `device.device_token &&` guard -> `if (!validateDeviceToken(device_id, device_token))`
   (validateDeviceToken already returns false for null-stored/missing/mismatch), and
   remove the legacy "mint a token for a null-token device" path (the re-provision
   vector). An already-provisioned device (every row, incl. 'provisioning', is created
   WITH a token) presenting null/empty/invalid is now REJECTED + disconnected.
   The first-pairing seam is unaffected: a brand-new device has NO device_id and goes
   through the pairing_code branch (which mints id+token) — a different code path.

2. No server-side kill switch. Added a `blocked` column (devices.blocked INTEGER
   NOT NULL DEFAULT 0; schema.sql + a database.js migration). The block is the FIRST
   gate at the top of device:register — before the fingerprint block, the reconnect
   throttle, any DB writes, or playlist build — so a blocked device's socket is
   refused immediately (auth-error 'Device blocked' + disconnect, zero further work).
   It does NOT rely on null-token (the thing that failed). The row is re-read every
   register, so a DIRECT SQLite edit takes effect on the device's NEXT reconnect with
   NO server restart. Operator statements (dashboard-down, hand-edit):
     block:   UPDATE devices SET blocked = 1 WHERE id = '<device_id>';
     unblock: UPDATE devices SET blocked = 0 WHERE id = '<device_id>';

Tests (port 3987): nulled-token provisioned device is REJECTED (75c2a08a repro);
blocked=1 refused at the first gate (no register/playlist); unblock reconnects;
first-pairing still works; normal valid-token device unaffected. Full suite green
serial AND parallel (213); reconnect-throttle.js + the dbac699 content-ack limiter
untouched.

ScreenTinker 29a8896aa8 fix(#142): global device_status_log retention sweep + STATUS_LOG_RETENTION_DAYS
The per-device insert-time prune (deviceSocket.js) only ever touches a device
that is actively inserting, so it misses two paths: removed/idle devices whose
rows linger forever, and heartbeat.js's offline_timeout insert that bypasses
logDeviceStatus entirely. The reporter's 1.2M-row bloat accumulated UNDER a 7-day
per-device prune for exactly this reason.

- pruneStatusLog() (db/database.js): a GLOBAL time-range sweep across ALL devices,
  modeled on the play_logs prune. Run once on startup (recovers a bloated table
  right after deploy) and on the heartbeat interval (services/heartbeat.js).
- STATUS_LOG_RETENTION_DAYS env, default 3 (lower than the old hardcoded 7d; the
  dashboard only shows a 24h uptime window, so 2-3d is ample for diagnostics).
- Deliberately NO per-device row cap: Step 3's throttle already bounds how fast a
  storming device can generate status rows, so a cap would add sweep complexity
  for little gain (noted for later if needed).
- NO VACUUM / auto_vacuum here (kept off the hot path); space reclaim is left as a
  separate decision (see report).

test: deterministic in-process unit test proves the sweep deletes over-retention
rows across all devices — including a device absent from the devices table and an
offline_timeout row — while keeping recent rows; idempotent on an empty table.

ScreenTinker ed3cf72b82 feat(#142): event-loop lag telemetry (perf_hooks) + bounded storage
Continuously samples event-loop delay via perf_hooks.monitorEventLoopDelay()
(C++-backed histogram; cheap). Each window persists mean/p50/p99/max to a new
event_loop_lag table and recomputes a coarse load band (normal/elevated/critical)
from the window p99. Standalone value: current lag is exposed on /api/status and
band changes are logged, so site lag is diagnosable independent of throttling.

The band feeds the #142 reconnect throttle (next commit) but ships first as its
own subsystem.

- event_loop_lag is bounded from day one: indexed on sampled_at + scheduled prune
  (LAG_TELEMETRY_RETENTION_DAYS, small default) modeled on the play_logs prune.
  Deliberately NOT another unbounded-growth table.
- Band transitions are asymmetric: jump up immediately (tighten fast), release one
  level at a time after N calm samples below a deadband (release slow, no flap).
  Pure nextBand() function, unit-tested deterministically.
- config: LAG_SAMPLE_INTERVAL_MS, LAG_RESOLUTION_MS, LAG_TELEMETRY_RETENTION_DAYS,
  LAG_PRUNE_INTERVAL_MS, LAG_ELEVATED_MS, LAG_CRITICAL_MS, LAG_RELEASE_SAMPLES.
- tests: band-transition unit tests; integration proves sampling persists, stays
  bounded under the prune, and surfaces on /api/status.

ScreenTinker d90cfb3986 fix(#142): index device_status_log + de-dupe its CREATE TABLE
The dashboard uptime query (WHERE device_id=? AND timestamp>?) and the
per-device retention prune (WHERE device_id=? AND timestamp<?) were both full
table scans. At 1M+ rows (the outage report) this was the dashboard-degradation
cause that persisted even after the reconnect storm stopped.

- schema.sql: add idx_device_status_log_device_ts(device_id, timestamp); both
  queries now SEARCH ... USING INDEX instead of SCAN (verified via EXPLAIN).
- database.js: same index as a migration for existing DBs (idempotent).
- schema.sql defined device_status_log twice; drop the duplicate.

ScreenTinker 0c0a8dd68a fix(ota): surface stuck OTA on dashboard + read APK signer correctly on API 28/29 (#139)
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.

fix(#134): quiet false "reconnect" log + report HDMI output and UI render resolution (#136)
Two device-REPORTING fixes from the #134 investigation (the PiP rendering itself
was #135).

1) "Device reconnects every ~45s" was a logging artifact, not instability. The
   player re-emits a full device:register on the SAME socket every ~45-60s
   (requestPlaylistRefresh) to pull a fresh playlist; the server logged
   "Device reconnected" for every register of a known device. The attached 4-day
   log showed 1415 "reconnected" vs 30 real socket connects and 0 heartbeat
   timeouts — the socket never dropped, so #134's "PiP lost between reconnects"
   was a misdiagnosis. Fix: only log a genuine reconnect (new socket); a
   same-socket re-register is a refresh (currentDeviceId === device_id) and stays
   quiet. The playlist still refreshes.

2) Device reported 720p while the monitor showed a 1080 signal. DeviceInfo
   reported getRealMetrics() — the UI RENDER SURFACE — but TV boxes render the UI
   at 720p and upscale to a 1080p HDMI signal. Now report BOTH: screen_width/height
   = the output mode (Display.Mode.physicalWidth/Height), render_width/height =
   the render surface (getRealMetrics). Two new nullable devices columns, stored on
   pairing INSERT + reconnect UPDATE, exposed via the device API, shown on the
   dashboard as "1920x1080 (UI 1280x720)" when they differ.

Backward compatible (required + verified on emulator): a device that omits
render_* — or sends no device_info at all — still registers, with render_* = null,
on both the INSERT and UPDATE paths. New columns nullable; stores use
`?? null` / `|| null`. All 167 server tests pass.

Fix per-item mute (#129): persist, ship to device, and toggle in real time (#130)
* fix(server): persist + ship + real-time per-item mute (#129)

The dashboard mute toggle was a no-op end to end. The active model is playlist_items
(the device payload is its published_snapshot); the legacy `assignments` table the bug
report cited is unused for devices. Three breaks:

- PUT /api/assignments/:id silently dropped `muted` (only read sort_order/duration_sec/
  zone_id). It now accepts muted (coerced 0/1) and ITEM_SELECT returns it, so the toggle
  persists and its on/off state sticks.
- playlist_items had no `muted` column — added (schema + idempotent migration).
- buildSnapshotItems didn't select muted, so it never reached the published_snapshot /
  device payload — now included.

Real-time: on a mute change, emit device:mute-changed { content_id, widget_id, muted } to
every device on that playlist so the player toggles the matching item's volume live,
decoupled from publish (the value is also in the next snapshot, so it persists). Adds a
[mute] log line (the report noted zero mute log entries).

Test: test/mute.test.js — PUT persists + returns muted, it reaches the published
snapshot, and a non-mute update doesn't reset it. Server suite 164/164.

* fix(player): apply per-item mute live on Android + web (#129)

Honor the new per-item mute from the server, both in real time and on reload.

Android:
- WebSocketService: onMuteChanged callback + main-thread device:mute-changed handler.
- MediaPlayerManager.setVideoMuted(): flips the live ExoPlayer volume on the current
  video (YouTube autoplays muted; images/widgets are silent).
- MainActivity: on device:mute-changed, apply immediately if the toggled item is the
  one playing now.
- PlaylistController.sig(): include muted so a published mute change re-renders/persists
  instead of being de-duped.

Web player (server/player/index.html):
- device:mute-changed handler toggles the current <video>; the video mount now also
  honors item.muted so a published mute sticks across reloads.

Tizen intentionally not included: its player mutes ALL video for autoplay, so per-item
unmute isn't achievable there.

ScreenTinker 5d24c30ea1 feat(displays): drag-to-reorder display tiles within a section (#106)
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.

ScreenTinker 400a438fff revert: drop zone-binding, keep whole-playlist grants + size-guidance card (#73)
Investigation found zone placement is a DEVICE property (device.layout_id), not a playlist
property: a normal playlist has no derivable layout (zone_id is NULL unless set in the
device-assignment flow), so a playlist-scoped zone grant can't reach the normal flow. The
right model: placement belongs to the device (same playlist can be full-screen on one screen,
a zone on another); the agency just gets whole-playlist grants + size-guidance.

Removed the zone-grant machinery (security-adjacent dead surface is a liability, not dormant
convenience): api_token_target_zones (schema + a DROP migration for the dev DB where the
short-lived CREATE ran), resolveGrantedZone, grantableZoneIds, buildZoneGrantRows, the
create/PUT zone validation, GET /api/playlists/:id/zones, getPlaylistZones, the settings
zone-picker + its i18n, and the zone-grant bite-test.

KEPT (model-agnostic, good): the reactive per-playlist size-guidance card - GET
/api/agency/playlists/:playlistId/layout (router.param-confined) now reports the zones the
playlist actually feeds (where/what-size content lands), or full-screen when it has no layout.
Whole-playlist grants = today's working model. 147 suite green.

ScreenTinker 289d54f4fa feat(api): zone-grant confinement for agency tokens - FK-anchored (#73)
Placement-as-grant, replacing the inferred auto-place idea. api_token_target_zones is an
ADDITIVE second table (does NOT touch the proven api_token_targets), structurally anchored:
a composite FK to api_token_targets(token_id, playlist_id) makes a zone grant orphan-
impossible and cascade away when the playlist grant is revoked - "narrow" is structural, not
conventional. zone_id FK -> layout_zones cascades on zone/layout delete.

Confinement (lib/agency-targets.resolveGrantedZone, called in the item-add): grants exist ->
the item MUST land in a granted zone (a body zone_id picks among grants, never escapes them);
none -> whole-playlist/full-screen as before. The item-add stamps the granted zone_id.

Bite-tested (6, all proven incl. neutralize->red on the confinement): granted YES; non-
granted/cross-playlist/ambiguous blocked; orphan-grant rejected by the FK; cascade on
playlist-grant revoke, on playlist delete, on zone/layout delete; and foreign_keys=ON
asserted (a cascade that no-ops because FKs are off is the trap). 153 suite green.

ScreenTinker c55ca60b56 feat(api): batched email digest for agency uploads (#73)
Reuses the existing scheduler + sendEmail infra (no new scheduler). The agency endpoint
enqueues one agency_notifications row per item added; a 15-min flush groups unsent rows per
token+playlist+action and sends ONE digest per group to the workspace owner/admins + the
playlist owner (deduped via UNION). Draft -> "added N items, awaiting approval"; published ->
"updated <playlist>".

Two robustness rules, both tested:
- Queue never balloons when SMTP is off: the endpoint skips enqueue when !isConfigured(),
  and the flush drains-and-discards unsent rows as a backstop.
- sent_at is stamped ONLY after a successful send, so a failed send retries next cycle
  instead of silently dropping.

Wired into boot via startAgencyDigest(). 147 suite green.

ScreenTinker 1f207c4278 feat(api): per-agency-token auto-publish (#73)
api_tokens.auto_publish (DEFAULT 0 = draft, the fail-safe). Admin sets it at token creation
in the designate UI (checkbox, agency scope only). The agency endpoint reads it from the
TOKEN ROW via req.apiToken (apiTokenAuth attaches it) - NEVER from req.body, so an agency
can't opt itself out of approval. 0 -> markDraft; 1 -> the shared publishPlaylist path.

Tests (integration): draft is the default; a draft token with auto_publish:true IN THE BODY
still lands draft (body ignored); an auto-publish token goes live; manual publish still works
(extraction regression). i18n across all 5 locales. 141 suite green.

ScreenTinker c8a24d2243 feat(api): agency-token security primitive - off-ladder scope + agencyGate (#73)
The capability/target-restricted token model for the agency portal (#73 option B),
proven before any endpoint sits on it:
- 'agency' scope value is OFF the read/write/full ladder, so the existing tokenScopeGate
  rejects it on every public router by construction (auto-confinement, no new code).
- api_token_targets join table: which playlists an agency token may act on.
- agencyGate: THE single seam - agency-scope-only + (playlist in this token's allowlist
  AND in the bound workspace), one query enforcing target + cross-workspace isolation.
- AGENCY_ROUTERS category in config/api-surface.js (mounted with agencyGate, not
  tokenScopeGate) - declared; router/mount land with the endpoints.

Both bite-tested: spine (agency 403s on tokenScopeGate; read/write still pass) and the
gate (non-designated/cross-workspace/non-agency/JWT -> 403; neutralizing the target check
goes red). NARROW - not the general capability-scope system.

ScreenTinker 73ca3cf258 feat(api): scoped API token foundation + secure-by-exclusion mounts
Introduce the public API's token layer and make the router partition data-driven.

- api_tokens table: SHA-256 hashed secret, st_ prefix, workspace-bound, read/write/full scope.
- middleware/apiToken.js: bearerAuth front door (Bearer st_ -> token auth, else the
  unchanged requireAuth); apiTokenAuth acts as the owner with platform powers stripped
  to 'user' and the workspace binding made authoritative (X-Workspace-Id ignored);
  tokenScopeGate (read=GET, write=mutations) + requireScope('full') for commands.
- config/api-surface.js: single source of truth for the PUBLIC (token front door) vs
  JWT-ONLY (requireAuth) router partition. server.js mounts from these lists so the
  mount list and the partition firewall test cannot drift.
- device-groups: operational group commands (reboot/shutdown) require the full scope.

A Bearer st_ token fails jwt.verify on the JWT-only routers (401), so privileged
surfaces (admin, workspaces, ai, provision, white-label) are unreachable by exclusion.

ScreenTinker 2ccf3264a9 feat(scheduling): per-item schedule blocks (#74 dayparting, #75 auto-expire)
Some checks are pending
CI / Unit tests (node --test) (push) Waiting to run
CI / Android unit tests (Kotlin schedule evaluator vectors) (push) Waiting to run
CI / Boot smoke + version check (push) Waiting to run
Each playlist item can carry schedule blocks (active days, start/end
time-of-day, optional start/end dates). An item plays when the screen's
local "now" matches at least one block; an item with no blocks always
plays. #74 covers time-of-day/day-of-week windows including overnight
wrap; #75 covers inclusive date ranges (auto-expiry). Evaluation is
on-device, so dayparting and expiry work offline.

- Shared evaluator contract: shared/schedule-vectors.json (39 vectors —
  DST US+AU, overnight-wrap anchoring, timezone correctness, date
  boundaries). Canonical JS evaluator in server/lib/schedule-eval.js;
  Kotlin and Tizen ports kept in lockstep by drift guards (Tizen byte-diff
  test, Kotlin JUnit reads the shared JSON, new android-test CI job).
- All three players (web, Android, Tizen) filter by schedule against their
  own clock, idle with a "Nothing scheduled" message + 30s re-check when
  everything is filtered, and fail open on any evaluator error.
- Editor: per-item schedule modal + row badge in the playlist editor;
  client validation mirrors the server; editing marks the playlist draft.
- Part B (behaviour change): device/group schedule overrides now evaluate
  in each device's effective timezone instead of server-local time.
- Device detail shows the reported timezone + a clock-skew warning.
- i18n for en/es/fr/de/pt across all new strings (namespaced itemsched.*
  to avoid colliding with the device-schedule calendar's schedule.*).
- CHANGELOG documents the feature, the Part B change, the fail-open
  guarantee, and the scheduled-single-video re-render tradeoff.

ScreenTinker dc6424a3cc feat(ai): separate optional image API key (#41)
Image generation reused the single (text-endpoint) API key, which breaks the
common 'local LLM with no key + OpenAI for images' setup. Add an optional
image_api_key (encrypted, write-only, never returned); generate-design uses it
for image calls and falls back to the main key when blank (all-OpenAI setups).
Local sd.cpp / ComfyUI still need no key. Schema column + migration.

ScreenTinker 303c83e86a feat(ai): generate background + foreground images for signs (#41 Phase 2)
A prompt now produces a full sign: the LLM writes the design AND image prompts,
the server generates the images and composites them with the crisp text layer.

- lib/image-gen.js: text-to-image with 3 BYO/self-hostable backends, all behind
  the SSRF guard: 'sdcpp' (local stable-diffusion.cpp OpenAI-compatible server,
  exact small sizes that fit VRAM), 'openai' (cloud / OpenAI-compatible, snapped
  sizes), 'comfyui' (prompt/history/view API).
- ai.js: prompt asks for a background_prompt (preferred — full-bleed atmosphere)
  and an optional foreground image element; after the design is normalized, the
  bg + fg images are generated best-effort (a failed image never fails the sign)
  and returned as data URLs. New image_* settings (provider/base_url/model),
  image_provider whitelist, schema column + migration.
- designer.js: AI-images section in settings; generate applies the background
  image; publish bakes the background image into the HTML so it survives.
- server.js: raise JSON body limit to 12mb for embedded image data URLs.

Verified end-to-end on local Vulkan SDXL (RTX 5090): prompt -> bg+fg images on
the canvas -> publish creates a widget with the images embedded. 63/63.

Note: prod (not self-hosted) requires a PUBLIC image endpoint (e.g. OpenAI); the
SSRF guard blocks localhost there. Follow-up: upload generated images to the
content store and reference by URL to avoid multi-MB widget configs.
2026-06-09 13:40:14 -05:00
ScreenTinker 0ba36949cf feat(ai): AI content design in the Designer, BYO endpoint (#41 Phase 1)
Competitor pressure (Mandoe 'AI Magic Create'): prompt -> signage. We answer it
in a way that's actually BETTER for signage and costs the operator nothing.

Key idea: don't generate raw images (AI garbles text - fatal for menus/promos).
The LLM returns a STRUCTURED design spec (headline, supporting text, accent
shapes, palette) that the existing Designer renders with real fonts - crisp and
fully editable. Reuses the whole Designer.

BYOK, fully under the customer's control: each workspace configures its own
OpenAI-COMPATIBLE endpoint + key - OpenAI cloud OR self-hosted (Ollama / LM Studio
/ llama.cpp). Operator bears zero AI cost/liability.
- server/lib/secretbox.js: AES-256-GCM for the key at rest (never returned).
- routes/ai.js: GET/PUT /api/ai/settings (admin; key write-only) + POST
  /generate-design (editor+). Output is strictly validated/normalized (cap count,
  clamp ranges, px->%, strip HTML, validate colors) - never trust the model.
  SSRF guard: hosted instances block private/internal targets; self-hosted (the
  whole point of local AI) may point at localhost/LAN.
- Designer: an 'AI generate' panel (prompt + Generate) + a settings modal.

Verified end-to-end against local Ollama (llama3.1:8b): prompt -> editable design
on the canvas. Unit tests cover normalization + the SSRF guard. Suite 61/61.

Phase 2 (next): AI background images (OpenAI images / AUTOMATIC1111).

ScreenTinker cb21b8e34a fix(layouts): atomic zone save (stop template zone duplication)
Saving a layout grew its zone count on every server restart. Root cause: the
editor saved zones with a per-zone delete-then-POST loop, and POST /zones minted
a NEW uuid for every zone - so each save replaced the seeded ids (z-sh-1, ...)
with fresh uuids. schema.sql re-seeds template zones via INSERT OR IGNORE on every
boot, so the next restart re-added the now-missing canonical zone alongside the
renamed copy -> a 2-zone template became 4, 6, ... (worse for self-hosters who
rebuild often).

Fix:
- PUT /api/layouts/:id now accepts a zones[] and replaces them atomically in one
  transaction, REUSING each zone's id when supplied. The editor sends the full
  set in a single call, so the layout ends up with exactly those zones and ids
  stay stable (also fixes fit_mode not persisting, and stops device->zone
  assignments being orphaned by id churn).
- One-time dedupe migration removes positional-duplicate template zones, keeping
  the canonical 'z-...' seeded id so the re-seed stays an idempotent no-op.

Verified: 2 atomic saves keep count + ids stable with fit updated; dedupe restores
a polluted 4-zone split template to its 2 canonical zones. Suite 56/56.

ScreenTinker bae70e9154 fix(db): count only ADD COLUMN as new migrations in boot log (#37 follow-up)
The boot summary counted any non-throwing statement, so UPDATE/index migrations

ScreenTinker 7ab19adcea fix(db): observable migrations + fail-fast schema verification (#37)
Self-hosters rebuilding could end up schema-behind-code, failing only at runtime
(a missing users.must_change_password locked out all logins). Two root causes:

1. The migration loop swallowed EVERY error (catch {}), so a real ALTER failure
   was indistinguishable from the benign 'duplicate column' on an already-migrated
   DB. Now only 'duplicate column'/'already exists' is treated as a no-op; any
   other error is logged loudly, and a one-line summary reports how many new
   column migrations actually applied this boot.

2. Nothing verified the schema after migrations. Added lib/schema-check.js:
   verifyAndRepairSchema() checks the tables + columns the request path REQUIRES,
   idempotently repairs missing repairable columns (logging each), and if anything
   required is STILL missing, prints a loud FATAL block and exits - failing fast at
   boot instead of at the first authed request.

Note: the reported 'audit_log missing' was a misdiagnosis - the code uses
activity_log (0 refs to audit_log), created by schema.sql on every boot.

Tests: healthy (no-op), auto-repair of must_change_password, missing-table report.

ScreenTinker 8fd971405e feat(layouts): per-zone fit mode + default to 'contain'
Multi-zone videos/images were cropped: every template zone inherited fit_mode
'cover' (fill+crop) and the layout editor had no control to change it, so a
landscape video in a tall split zone showed only a center strip. The player
already honors fit_mode (web object-fit, Android scaleType) - the gap was the UI
and the default. Add a per-zone Fit selector (Contain/Cover/Stretch) to the layout
editor, and make 'contain' (show the whole frame) the default for new zones, the
schema column, and the save fallbacks. Existing built-in templates are migrated
separately.
