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

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).

A mute toggle wrote the draft playlist_items + emitted a live device:mute-changed but only markDraft()'d — it never updated playlists.published_snapshot, the copy the device actually plays. So the device's item.muted stayed 0 and every loop/reload re-applied full volume: dashboard icon red but audio kept playing (Android; web's native <video> loop masked it). emitMuteChanged now surgically patches the matching item's muted (0/1) inside the published_snapshot and re-pushes the playlist, so loops re-apply the correct flag. Surgical patch (not publishPlaylist) so a mute toggle can't prematurely publish other draft edits or flip publish state. Adds a regression test that fails without the patch.

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.

* 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.

Phase 2 (assignments -> playlist_items) dropped zone_id during the
conversion: migrateAssignmentsToPlaylists INSERTed only (playlist_id,
content_id, widget_id, sort_order, duration_sec), and the new
playlist_items DDL omitted the zone_id column entirely. Every write
path on top of playlist_items inherited that omission - the
multi-zone layout assignment feature stopped working.
Frontend always sent zone_id correctly (device-detail.js:1015,1072
POST and PUT both include it; api.addAssignment and api.updateAssignment
forward the body verbatim). Server silently dropped it. The
assignments.js PUT route was the most direct evidence: it destructured
zone_id from req.body but never added it to the updates array.
Schema:
- schema.sql: add zone_id TEXT REFERENCES layout_zones(id) ON DELETE
SET NULL to fresh-install DDL.
- database.js migrations[]: add idempotent ALTER TABLE for existing
installs (the surrounding try/catch loop handles duplicate-column).
Backfill (new gated migration phase2_zone_id_backfill):
- Pre-migration snapshot copied to db/remote_display.pre-zone-id-
backfill-<ts>.db (one-off for this migration; the general
every-migration-snapshot framework is a separate concern, not built
here).
- Best-effort UPDATE playlist_items.zone_id from surviving
assignments rows via device.playlist_id + content_id/widget_id
match, LIMIT 1 for the multi-match edge case.
- Regenerates published_snapshot for every published playlist so the
JSON the player consumes carries zone_id going forward. Even with
zero rows backfilled (the common case post-Phase-2 cleanup) this
closes the snapshot-staleness gap.
- Stamps schema_migrations regardless so it won't re-run on next boot.
- On the live local DB: 0 playlist_items backfilled, 18
published_snapshots regenerated. On the April 13 prod fixture
(sandboxed copy): 0 backfilled, 7 regenerated. Expected and matches
our pre-flight finding that assignments was effectively scrubbed of
zone_id everywhere.
Route wiring (7 sites + 1 shared constant):
- assignments.js ITEM_SELECT: project pi.zone_id (read path so the
frontend display at device-detail.js:500 surfaces the value).
- assignments.js POST INSERT: include zone_id column + value.
- assignments.js PUT: actually use the already-destructured zone_id
in the updates allow-list. Treats undefined as "no change" so a PUT
that omits zone_id leaves the existing value intact; any explicit
value (including null) is written.
- assignments.js copy-to INSERT: preserve a.zone_id during
device-to-device playlist copy.
- playlists.js buildSnapshotItems: project pi.zone_id so the snapshot
JSON carries it. This is what the player's renderZones loop reads
(player/index.html:1338 matches a.zone_id === zone.id).
- playlists.js discard-revert INSERT: restore zone_id from snapshot
item on revert.
Out of scope (verified safe by SQL semantics + UI inspection):
- playlists.js POST item-add and PUT item-update in the playlist-detail
surface: the UI there doesn't expose zone editing, and their SQL
leaves zone_id NULL on insert / untouched on update. No regression.
- Other playlists.js SELECT projections (lines 141, 190, 240, 265, 334,
379, 419) all use SELECT pi.* and auto-pick zone_id once the column
exists.
- Kiosk-page assign at device-detail.js:1027 doesn't send zone_id;
separate pre-existing gap, not part of this regression.
Tests (all local, no push, no prod deploy):
- Migration boot on live local DB: clean, idempotent (second boot
skips the gated function).
- Migration boot on April 13 prod fixture (sandboxed copy at
/tmp/zone-fix-fixtures/test-run.db): cleanly runs the full migration
stack (multi-tenancy + 5 other phases the fixture predated) then
the new zone_id backfill. Live local DB untouched.
- 8 SQL-level route behavior tests pass: INSERT stores zone_id, PUT
changes/clears zone_id, ITEM_SELECT and buildSnapshotItems
projections include zone_id, copy-to preserves, discard-revert
restores from snapshot JSON, undefined zone_id in PUT leaves
existing value intact.
Not verified: end-to-end multi-zone playback on a real device. The
SQL + snapshot JSON layer is correct (player consumes
playlist.find(a => a.zone_id === zone.id) and now gets the right
zone_id back from the snapshot); confirming render-to-correct-zone
on actual hardware is the next step before prod deploy.

Security fixes:
- Critical: Add ownership checks to assignments PUT/:id and DELETE/:id (IDOR)
- Critical: Add ownership checks to assignments copy-to endpoint for both devices
- High: Validate device ownership when adding to device groups
- High: UUID-validate content ID before LIKE query + scope to owner's playlists
- Low: Handle FK violations gracefully in playlist discard (deleted content/widgets)
- Low: Escape mime_type with esc() in playlist item display (XSS)
Bug fix:
- Device-detail mutation handlers now reload full page to show draft banner

Remove autoPublish from assignments.js and device-groups.js. All item
mutations (add, update, delete, reorder, copy) now call markDraft
regardless of which UI the edit comes from. Users must explicitly
click Publish to push changes to devices.

Schema: add status and published_snapshot columns to playlists table.
Migration snapshots all existing playlists as published (idempotent via schema_migrations).
Devices always receive the published_snapshot, not live playlist_items.
Edits from device-detail/groups auto-publish immediately (display updates instantly).
Edits from playlist detail page go to draft (requires explicit publish).
POST /playlists/:id/publish snapshots and pushes to all devices.
POST /playlists/:id/discard reverts playlist_items from published snapshot.
Content deletion scrubs references from all published snapshots.
Frontend: draft badge in playlist list, prominent yellow banner with publish/discard
buttons on playlist detail and device detail pages.

All CRUD routes now read/write playlist_items via device.playlist_id.
Auto-creates a playlist for a device on first content add if none exists.
PUT/DELETE push updates to ALL devices sharing the same playlist.
Copy-to-device creates a playlist on the target if needed.

- Push playlist updates to devices instantly via WebSocket on all
assignment mutations (add, update, delete, reorder, copy)
- Fix YouTube videos skipping early: remove duration_sec timeout (was
defaulting to 10s), use generation counter to ignore stale player
callbacks, disable YouTube loop param for multi-item playlists
- Auto-fetch YouTube video title via oEmbed API when no name provided
- Show actual video duration in M:SS format in playlist instead of
misleading assignment duration_sec
- Pre-fill server URL from origin on web player setup
- Bump playlist poll interval to 5min (fallback only, push is primary)
