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.

ScreenTinker 4547a677ab test(#146) P3.9: de-flake storm harness — keep max-gap invariant, drop tick-count
The storm harness asserted a tick COUNT (environment-timing-sensitive) that could flake
in CI. Kept the real invariant (max event-loop gap < 300ms) and loosened the tick
assertion to >=2 (enough to have measured a real gap), which cannot flake.

ScreenTinker bfa99771ca feat(#146) P3.8: soak observability block on /api/status
Expose the new internal states so we can SEE the limiters biting during the alpha soak
instead of grepping logs. /api/status now carries debug: {
  flap: {buckets, quarantined},
  ota_download: {inFlight, servedThisWindow, shedThisWindow, windowCount},
  maintenance: {deleted, ms, at, running},   // last status-log prune
  log_coalescer_buffer,
}. Aggregate counts only (no device ids/secrets), cheap in-memory reads. stats()
added to flap-limiter + ota-download-guard (singleton prod state), getMaintenanceStats
from database. Asserted in the booted /api/status test.

ScreenTinker 0f990c2e7e fix(#146) P3.7: coalescer carries the PEAK numeric over the window
The coalesced loop-lag summary carried an arbitrary sample's p99. Now record() tracks
the MAX (peak) over the window and the summary emits it — the peak is the number that
matters during an incident: '[loop-lag] band=critical (x47 in 30s, peak 1502ms)'. Band
CHANGES still log immediately, unchanged.

ScreenTinker 7e68e18a17 test(#146) P2.6: boot health during a large startup trim — confirmed
Booting against a pre-bloated 300k-row device_status_log, /api/status answers in <3s
while the table is still large (chunked startup prune trickling in the background), and
the backlog drains to the cap with the server responsive throughout. The old whole-table
sort froze boot ~40s. Fallout doc gets the P2 findings section.

ScreenTinker a80f0b8f6f test(#146) P2.5: buildPlaylistPayload cost under mass reconnect — mitigated
Investigated the fleet-wide simultaneous reconnect concern. buildPlaylistPayload is
synchronous but cheap: measured avg 0.078ms / max 0.70ms per call with a 200-item
snapshot; 230 devices = ~18ms CPU spread across 230 separate handler invocations (the
loop yields between them), never one block. Per-call << 50ms invariant. No change
needed; documented with the measured number.

Block is a real lever now, so cover the authz path. Booted server + JWT; device and a
viewer membership seeded via the DB file. Proves POST /api/devices/:id/{block,unblock}:
owner (workspace_admin) -> 200; unauthenticated -> 401; cross-workspace user -> 403;
workspace_viewer -> 403 (read-only), with the DB blocked column asserted at each step.

ScreenTinker 8dd6491288 fix(#146) P1.3: per-feature env kill switches + fallout doc section
Every new subsystem is disable-able via env (flip + restart, no redeploy/bisect):
- FLAP_LIMITER_ENABLED=false -> flap limiter always allows.
- OTA_DOWNLOAD_GUARD_ENABLED=false -> download guard always admits.
- MAINTENANCE_BAND_GATE_ENABLED=false -> interval maintenance ignores band.
- CONNECT_RATE_QUARANTINE_TRIPS=0 -> quarantine off (already; confirmed).
Startup prune is never band-gated regardless. Kill switches table added to the fallout
doc. Tests assert each OFF behaviour.

ScreenTinker 067aebfd75 fix(#146) P1.2: band-aware download caps — serve freely when healthy
A fixed OTA_DOWNLOAD_MAX_CONCURRENT=10 throttled a legitimate coordinated rollout even
on a perfectly healthy server, and a shed 503 costs a client a full ~30-min re-check
cycle. Made the download guard's concurrency + rate caps band-aware:
  - normal   -> serve FREELY (no cap): a whole-fleet rollout isn't staggered when healthy
  - elevated -> the configured caps engage (early backpressure)
  - critical -> shed 503 (the real protection, unchanged)
Kill switch OTA_DOWNLOAD_GUARD_ENABLED=false disables it entirely.

Tests updated: normal serves 50/50 with 0 shed; caps + shed now asserted under elevated;
storm harness OTA flood runs under elevated (the loaded state). Suite green.

ScreenTinker d4b2532c9a fix(#146) P1.1: resolveIdentity short-circuits on device_id (zero-lookup hot path)
resolveIdentity runs on every register (block + flap gates). It already returned on
device_id before any DB access; memoized the device_fingerprints statement (prepared
once, lazily) and documented the invariant. Test asserts a device_id-present resolve
prepares/runs ZERO device_fingerprints queries; a device_id-absent resolve does.

ScreenTinker 317754376c fix(#146) P0: auto-quarantine is in-memory + time-limited, never a DB block
The flap limiter's auto-quarantine used to run `UPDATE devices SET blocked = 1` — a
PERMANENT, human-cleared block on an automatic trigger. A stuck-then-recovered device
stayed dark until someone noticed.

- Removed the auto-write from ws/deviceSocket.js. devices.blocked is now written ONLY by
  an operator (dashboard endpoint / direct SQLite).
- Quarantine moved into lib/flap-limiter.js as IN-MEMORY, TIME-LIMITED state: after
  connectRateQuarantineTrips trips in a window the identity is quarantinedUntil = now +
  connectRateQuarantineMs (new, default 30m); check() then refuses cheaply with
  reason:'quarantined' and AUTO-CLEARS when the window passes. Safe in-memory now that
  Item A ended the restart loop, and a self-healing auto-action must not survive as a DB row.
- Log quarantine START once; repeat refusals go through the coalescer. Stale
  "-> blocked=1" comments updated.
- connectRateQuarantineTrips=0 still disables it.

Tests: quarantine engages after N trips, refuses cheaply during the window, auto-clears
after connectRateQuarantineMs; and an integration flapper is quarantined while
devices.blocked stays 0.

ScreenTinker 4a8d13d288 test(#146): storm harness — the bulletproof proof
Combines all four spiral inputs at once: a pre-bloated device_status_log (300k rows), a
maintenance sweep running over it (the old whole-table sort froze 40-48s), a hard
flapper, and an OTA download flood from a single SNAT IP. Asserts:
  - the event loop never enters a multi-second freeze (max 10ms-ticker gap < 300ms,
    vs 40-48s pre-fix) and the ticker keeps firing throughout,
  - the chunked sweep drains the 300k backlog to the per-device cap,
  - every limiter still bites under load: the flapper is refused, the OTA flood is shed
    past the global window cap (served capped, never per-IP).

Suite 267/267.

ScreenTinker 4bda49cf60 fix(#146) E: log/write self-protection — coalesced logs, batched telemetry, bounded maps
Don't let telemetry/logging cook the loop under a storm.

- lib/log-coalescer.js: dedup+count high-frequency lines, flush ONE summarized line per
  key per window ("[loop-lag] band=critical (x47 in 30s)"). Bounded buffer (auto-flush
  at MAX_KEYS). Applied to the loop-lag "still loaded" line (band CHANGES stay immediate),
  the per-request OTA check line, and "Device reconnected".
- loop-lag: event_loop_lag rows are BUFFERED and batch-inserted on a flush interval
  (was a synchronous INSERT per sample); the buffer is bounded (drop-oldest). Its
  retention prune now rides the Item-A chunkedDelete so this table can never repeat the
  status_log bloat-then-freeze. /api/status still reads in-memory current (real-time
  band unaffected).
- Bounded the previously un-evicted per-device Maps: content-ack limiter gets an idle
  sweep (started in server.js); status-log-writer.lastWritten is capped (drop-oldest;
  it only suppresses a redundant consecutive row, so eviction is safe).

Tests: N identical lines -> one counted line; single line verbatim; coalescer buffer
bounded under a distinct-key flood; content-ack Map swept of idle buckets.
loop-lag-integration updated for the batched-insert cadence. Suite 266/266.

ScreenTinker 97d489223f fix(#146) D: operator block — close the device_id-less gap + dashboard toggle
- Enforcement (deviceSocket): resolve identity ONCE via the SNAT-safe chain and check
  blocked against the RESOLVED device_id (device_id directly OR fingerprint->device_id),
  so a blocked device that reconnects WITHOUT a device_id is still caught — the old
  "if (device_id)" gate let a device_id-less reconnect slip past. Still the first gate,
  before flap/throttle/DB/playlist. Nulling the token still does NOT block (it
  re-provisions) — the blocked column is the lever.
- Dashboard toggle: POST /api/devices/:id/{block,unblock} (write-gated + workspace-scoped
  via checkDeviceOwnership) writes devices.blocked; takes effect on the device's NEXT
  register with no restart. api.js + a Block/Unblock button in device-detail.js.
- Outage procedure documented in-code: direct SQLite
  "UPDATE devices SET blocked = 1 WHERE id = <id>" works with the dashboard down.

Tests: blocked refused at handshake with no playlist build; device_id-less reconnect
with a mapped fingerprint still refused; unblock effective on next register, no restart.
Suite 262/262.

ScreenTinker f037dd476a fix(#146) C: OTA hardening under SNAT — no per-request fs, global download caps
The fleet SNATs to one IP, so nothing on the OTA path may key on IP.

- /api/update/check: EARLY-RETURN before any filesystem call when the breaker won't
  offer (rate-backoff / up-to-date / phantom / client-newer). A looping client that
  gets rate-backoff now does ZERO fs — the flood can't become a statSync flood.
- lib/apk-cache.js: resolve APK path/size/mtime once at boot + refresh on an interval;
  the check/download endpoints read cached metadata (get() does no fs, proven by test).
- lib/ota-download-guard.js + /download/apk: GLOBAL concurrency + rate caps + critical-
  band shed (503 Retry-After), NEVER per-IP. Replaces the per-IP-per-10min log throttle
  (which hid the flood under SNAT) with a per-window served/shed aggregate so a download
  flood is VISIBLE. Bounded single rolling-state object; in-flight released on finish/close.
- Breaker unchanged; no IP limiting or device_id requirement added (legacy field clients
  send no device_id on OTA checks — must keep working).

Tests: apk-cache get() = 0 statSync over 1000 reads; download guard sheds past global
concurrency + per-window rate + critical band; admit() has no IP parameter. Suite 259/259.

ScreenTinker 9e3222a503 fix(#146) B: sustained flap-rate limiter (the trigger fix), SNAT-safe identity chain
The #142 burst throttle (5/10s) misses a device flapping every 3-5s (~2-3/10s) — yet
each cycle is an expensive register+build+acks and one status_log row (the spiral
trigger). Now that Item A ends the restart loop that used to wipe in-memory throttle
state every ~40s, an in-memory sustained limiter can finally bite.

- lib/device-identity.js: SNAT-safe identity resolution — device_id -> fingerprint
  (map via device_fingerprints -> device_id, else raw fp) -> device_token -> ONE bounded
  global anon bucket. NEVER IP (the fleet SNATs to 10.10.10.1). An unidentifiable client
  is still bucketed (collectively) so an anon flood is capped, never unthrottled.
- lib/flap-limiter.js: per-identity connect-frequency over a long window
  (CONNECT_RATE_WINDOW_MS=5min, CONNECT_RATE_MAX=20; anon bucket cap 60). Over the rate
  -> refuse + disconnect (cheap). Bounded by an idle sweep (anon bucket never swept).
  Optional auto-quarantine: a device_id-resolved hard flapper -> blocked=1.
- Wired at the device:register gate BEFORE fingerprint tracking/throttle/DB/build,
  skipping same-socket playlist refreshes. Sweep started in server.js.

Tests: 4s-flapper refused after the window max; 60s-normal never; two device_ids
independent (never IP); device_id-less bucketed by fingerprint; neither id nor
fingerprint capped via global anon; idle sweep preserves the anon bucket. Suite 254/254.

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 cbf81a05a3 fix(#146): crash-hardening — one device's handler throw can't take down the fleet
Found in the alpha load test: client-chosen pairing codes collide by birthday
paradox, the provisioning INSERT hit UNIQUE(devices.pairing_code), the SqliteError
threw out of the (synchronous) socket handler -> uncaughtException -> logFatalAndExit
-> the WHOLE server exited and every device dropped. The colliding flood crash-LOOPED
the container (2 restarts).

Two layers, same "one device can't take down the fleet" theme as #142/#143/#144:

1. Narrow (deviceSocket.js): wrap the device:register provisioning INSERT in
   try/catch — a UNIQUE pairing_code collision (or ANY db error) rejects THAT
   registration (device:auth-error -> client retries) instead of throwing.
   currentDeviceId/authenticated now set only AFTER the row exists (no half-auth
   socket on failure).

2. Broader (lib/safe-socket.js): protectSocket() overrides socket.on per connection
   so any handler throw is caught, logged (event + id + stack), the socket told, and
   DISCONNECTED — per-CONNECTION fail-fast, not whole-PROCESS. We don't keep serving a
   connection from possibly-half-mutated state (honors the existing fail-fast intent),
   we just contain it to "one device reconnects" (a non-event after beta5). Wired into
   both the /device and /dashboard connection handlers; auto-covers future handlers.
   Audited first: no handler throws as control flow, so blanket-wrapping is safe.

Tests (mutation-verified, fail without their fix):
- register-insert-crash.test.js: a pairing_code collision AND a general bind error
  each reject-one-device with no uncaughtException; server keeps serving.
- socket-handler-isolation.test.js: a throwing handler disconnects only that socket;
  the server + other sockets stay alive.
Full suite 243/243.

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 289d6b6f95 fix(#144): OTA update-check circuit-breaker + phantom guard + per-device keying
/api/update/check offered the update whenever client !== latest (raw string
inequality, not semver) with no backoff. A device that can't APPLY the update
(broken OTA client 1.7.12, signing/Fire OS) keeps reporting the same version and is
told update_available=true on every poll; a fast poll loop saturates the event loop
(prod loop-lag 49s). All requests share one NAT IP, so IP-keying is useless.

server-only breaker (lib/ota-breaker.js), two independent axes:
- RATE breaker (primary, immediate): a key checking >THRESHOLD (3) times within
  WINDOW (60s) is looping -> throttle update_available with exponential backoff
  (30s->2m->8m->cap 30m). Healthy devices poll ~12 min and never approach this, so
  rollout/stragglers are inherently safe -- NO grace-for-flood timer; slow == safe.
- PHANTOM guard (immediate): unrecognized version, or a prerelease of an OLDER core
  (superseded old-minor beta e.g. 1.9.1-beta4), gets no-offer on the first check. A
  RECENT real older version (beta3 vs latest beta4; stable 1.7.12) stays offerable.
- Never offers a downgrade (client >= latest -> no offer).

KEYING (#144 option 3): keyed on device_id when present, else reported version.
- server.js:581 accepts + logs ?device_id=, passes it to the breaker.
- UpdateChecker.kt:122 appends &device_id=<config.deviceId> (existing registered id;
  omitted until provisioned). One-line client change.
beta4+ clients get precise per-device throttling; stuck legacy clients sending only
?version= are caught by the version-keyed + rate + phantom logic. Response gains
additive `reason` + `retry_after_seconds` (old clients ignore).

BOUNDED STATE: a periodic sweep (startSweep, wired in server.js) evicts buckets idle
> IDLE_RESET_MS so the keyed Map can't grow unbounded (churned device_ids); not
reset-on-access only.

SCOPE (deliberate): this targets the FAST flood + phantoms. The slow #144 drip
(stable 1.7.12 polling ~every 12 min, ~20/hr) stays below >3/60s and is NOT
throttled -- catching it needs #144 option-3 "skip-this-version after N cycles",
which is intentionally NOT in this build.

NOTE: carries a CLIENT/APK change -> versionCode must increment at the beta4 bump and
the release keystore is required for the APK. The device_id path only helps devices
that can install beta4+; the stuck legacy fleet is covered by the version-keyed path.

Tests: unit (lib/ota-breaker, injected time) a-f + comparator + escalation + sweep +
slow-drip-scope; HTTP integration (real endpoint, device_id passthrough). Full suite
green serial AND parallel (234). OTA-only delta -- reconnect/reclaim/shed/content-ack/
block untouched.

ScreenTinker 8d37c7f5ff fix(#143): notify a screen it's paired on reconnect (recovery-critical)
Bold: screens sit on the Connect page showing the server URL = paired server-side
but never told, so the app never starts playing.

Flow / gap (Step A):
- CLIENT leaves the Connect page ONLY on the 'device:paired' event — web player
  (player/index.html) hides the setup screen; Android ProvisioningActivity.onPaired
  launches MainActivity + finish(). That event is the sole signal.
- SERVER pushes 'device:paired' to the device's room from POST /api/provision/pair
  (server.js) at pair time — but ONLY reaches a LIVE socket then. The normal
  device_id reconnect path emitted device:registered + device:playlist-update but
  NOT device:paired. So a screen paired while disconnected, or that reconnects after
  pairing (exactly the screens cycling on the Connect page), is paired server-side
  (user_id set, receiving playlists) yet never gets device:paired -> stuck on Connect.

Fix (server-only, uses the EXISTING client listener — no client update needed, which
matters because we can't push a client update to stuck screens): on the device_id
reconnect, if the device is paired (user_id set), re-emit 'device:paired'
{device_id, name}. Push-on-pair (server.js) already covers the live-at-pair-time
case; this covers paired-then-reconnect. A paired screen now leaves Connect and
plays on its next reconnect with no client change and no manual re-pair.

Tests (port 3989, real flow): provision -> pair via /api/provision/pair (socket
closed) -> reconnect RECEIVES device:paired (+name +playlist) — the stuck-screen
repro; an unpaired device gets NO device:paired (stays on the pairing flow); the fix
reuses the existing device:paired event (no new protocol). Full suite green serial
AND parallel (220); dbac699 / 404c330 / e734281 intact.

ScreenTinker e73428182d fix(#143): fingerprint-reclaim stuck loop — reclaim by runtime liveness, throttle log
Bold beta1: three devices spam "Fingerprint reclaim rejected ... device active
(status=offline, ~2500s since heartbeat, liveConn=false)" twice/~2s indefinitely —
contradictory: gone by every signal yet treated as active.

Root cause (NOT a missing clear — corrected the hypothesis). The reject condition
was `liveConn || status==='online' || secondsSince < RECLAIM_GRACE_SECONDS(24h)`.
For the observed devices liveConn=false and status=offline, so the ONLY true term
is `secondsSince < 24h` — an effective 24h CALENDAR grace, not a stale flag. Audited
the clears: liveConn (deviceConnections) is removed on the debounced disconnect
(heartbeat.removeConnection) AND the offline_timeout sweep (deviceConnections.delete);
status is set 'offline' on both. liveConn=false + status=offline PROVE the clears
ran — there is nothing stale to clear. The 24h time gate (mislabeled "device active")
blocked a legitimately-gone device from reclaiming for up to 24h, so it retried
every ~2s forever-in-practice. The "twice per ~2s" is two reclaim ATTEMPTS per cycle
(client reconnect + re-pair-on-auth-error), each hitting the single console.warn —
not double-logging in one attempt.

Fix:
- Decide "still alive" from RUNTIME signals: `!!liveConn || secondsSince <
  reclaimSettleSeconds`. A device with no live socket and a heartbeat older than the
  settle window is gone -> reclaimable. A live (or just-seen) device is still
  rejected, so reclaim-abuse protection holds. NOT just ignoring "active" — it fixes
  WHY it was stuck (the 24h gate). RECLAIM_SETTLE_SECONDS default 300 (was 24h).
  SECURITY TRADEOFF flagged in config: shortens the anti-fingerprint-theft window;
  raise to re-tighten. Tuning guess to validate vs Bold.
- Log throttle: the deferral logs at most once per device per RECLAIM_REJECT_LOG_
  WINDOW_MS (default 60s) — collapses the double-log + the per-2s flood (same
  discipline as the content-ack shed log). Cleared when a reclaim proceeds.

Recovery of the 3 wedged devices (2febcaa9, 1984694c, 139159eb): they SELF-HEAL on
their next reclaim attempt (~2s) once this ships — their heartbeats are ~2500s stale
(>300s settle) and liveConn=false, so the reclaim now succeeds. No operator SQL needed.

Tests (port 3988): gone device reclaims; live device still rejected; clear-on-leave
(disconnect clears liveConn -> stale device reclaims); deferral log <=1 per window.
Full suite green serial+parallel (217). reconnect-throttle.js, the dbac699 content-ack
limiter, and the 404c330 block/auth code untouched.

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 dbac699854 fix(#143): content-ack flood control — per-device rate budget + loop-lag valve
#142's content-ack dedup is insufficient: a device cycling 2-4 content IDs makes
every ack look unique so dedup never fires, while aggregate volume from ~30 devices
saturates the event loop (the #142 reconnect throttle kept the server responsive,
which is how this was even observable).

Folded ONE control on the content-ack path (no competing limiters; reconnect-
throttle.js untouched) in lib/content-ack-limiter.js:
- Step 1 — per-device RATE budget: caps TOTAL non-duplicate acks per device per
  window regardless of differing content_id (the case dedup misses). Over budget =
  DROP silently (the per-ack log+emit is the cost); log ONCE per device per window
  when shedding starts. Keeps the #142 dedup (dedup'd repeats don't consume budget).
  Per-device, in-memory, resets on restart (modeled on lastPlayLogAt; does NOT reuse
  reconnect-throttle's ban-semantics bucket).
  Env (TUNING GUESSES, validate vs Bold's fleet): CONTENT_ACK_MAX_PER_WINDOW=20,
  CONTENT_ACK_RATE_WINDOW_MS=10000 (=2/s, above legit ~<=1/s, below the flood).
- Step 2 — global pressure valve: reuses the #142 loop-lag band (+ its hysteresis,
  no second control loop). Under CRITICAL band, shed content-acks even for an
  in-budget device; reconnects + dashboard/HTTP are ALWAYS processed; a healthy
  device in a non-critical band is never touched by the valve. Valve open/close
  logged once at the band edge in services/loop-lag.js (not per shed message).

Tests (unique ports 3985/3986, not the 3982/3983/3984 set):
- unit: the #143 regression (cycling ids evading dedup IS rate-limited), under/over
  budget, dedup still works + doesn't consume budget, valve sheds in-budget under
  critical while normal is untouched, rate precedence, window reset, per-device
  isolation.
- integration: socket flood is capped to budget with a single shed-start log;
  under-budget passes every ack; valve OPEN sheds content-acks while a reconnect +
  /api/status still succeed.
Full suite green serial AND parallel (208 tests).

ScreenTinker 139d7d09fa fix(#142): provisioning-row cleanup window 365d -> 24h (matches its own comment)
services/heartbeat.js deleted unclaimed provisioning devices with
created_at < now - (365 * 86400) — a YEAR — while its own comment said "older
than 24 hours". So socket-register pairing junk lingered ~365x longer than
intended. Change the window to 24 * 3600 to match the comment.

Correctness fix only — does NOT touch the pre-auth register path or add a rate
limiter (that pre-auth hardening is a separate security issue, out of this cut).

Extracted the sweep into pruneProvisioningDevices() (still in heartbeat.js, called
from the same interval) so it is unit-testable. Test asserts a >24h unclaimed
provisioning row is swept while a <24h row, an imported row (user_id set), and a
non-provisioning row are kept.

ScreenTinker 15448d1c5d fix(#142): dedup repeated content-ack reports (secondary load)
device:content-ack logged + emitted every message, so a device repeatedly
reporting the same "content <id>: ready" (observed from an older app version)
added avoidable load per message.

- Suppress identical (device_id, content_id, status) reports within
  config.contentAckDedupMs (default 10s), modeled on the lastPlayLogAt throttle.
  A status change has a different key and passes immediately; a fresh report after
  the window passes too. In-memory, resets on restart. The handler does no DB
  writes, so this is purely shedding redundant log+emit work.

test: integration over a real authenticated device socket — a burst of identical
"ready" collapses to one log/emit, a "ready" after the window passes, and a status
change is never deduped. Unique PORT (3984).

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 101f086204 fix(#142): load-aware per-device reconnect throttle (the outage fix)
Gates genuine reconnects PER DEVICE before the heavy register work (DB writes +
playlist build) runs, so a single flapping device can no longer saturate the
event loop and take down the server.

- Actuator is per-device, keyed on device_id (modeled on lastPlayLogAt). A device
  is flagged only when it exceeds reconnectBaseMax genuine reconnects per window.
  Same-socket playlist refreshes (isPlaylistRefresh) are exempt.
- Load-awareness is BANDED (normal/elevated/critical from the step-2 lag signal),
  not a continuous controller. The band only MULTIPLIES an already-flagged
  device's backoff; global lag never gates a healthy device.
- Hysteresis: escalate immediately while storming (tighten fast); decay one level
  per reconnectReleaseMs of calm (release slow).
- HARD CEILING per device, independent of band and warm-up — a slow-ramp attacker
  can't train through it.
- COLD START: for reconnectWarmupMs after boot, force the normal band and apply
  only the hard ceiling, so a full-fleet reconnect after a deploy doesn't throttle
  healthy screens. State is in-memory, resets on restart.
- Observability: every throttle engagement logs device, band, observed vs allowed
  rate, and backoff. Throttled device gets device:throttled + a deferred disconnect.

Tests (api.test.js style):
- unit: healthy-never-throttled, storm-throttled-with-growing-backoff, band
  multiplies backoff, hard-ceiling-even-in-warmup, warm-up leniency, neighbor
  isolation, slow release.
- integration GATE (the required one): full-fleet reconnect right after restart
  throttles NO healthy device; a single device storming IS throttled; a neighbor
  stays unaffected while another storms.
- also fixes pre-existing test PORT collisions (my new integration files clashed
  with totp.test.js:3979 and totp-keyrotation.test.js:3980 -> moved to 3982/3983);
  full suite now green serially AND in parallel.

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 071d7cc9c3 fix(server): persist per-item mute into the published snapshot (#129)
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.

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.

ScreenTinker a36880b147 fix: per-item mute round-trip + multi-zone orphan-zone fallback & warnings
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.

ScreenTinker 5f83fc20d3 docs(api): document /api/pip and the assignments muted field (#109/#129)
The PiP endpoints and the per-item mute field shipped without OpenAPI coverage.

- openapi.yaml: add POST /pip (show), DELETE /pip + POST /pip/clear (clear), all
  x-required-scope: full; add the `muted` boolean to PUT /assignments/{id}; add a `pip` tag.
- openapi-contract.test.js: the scope heuristic only treated `command` paths as full-scope,
  so a full-scope non-command route (/pip) would fail it — extend it to recognize /pip.

Docs-only as far as the running build goes (no route/behavior change). Lands on main; not
in the frozen v1.9.1-beta4 tag — ships in the next tag.

fix(server): proxy remote YouTube thumbnails + real version in boot banner (#131)
* fix(server): proxy remote YouTube thumbnails instead of ENOENT on a local path

YouTube content stores thumbnail_path as a REMOTE URL
(https://img.youtube.com/vi/<id>/hqdefault.jpg), but the thumbnail-serving route
path.resolve'd it into contentDir -> a local file that never existed -> ENOENT logged
a few times a minute (the tester-log spam). Recreating content didn't help (new rows
store the same remote URL).

- GET /api/content/:id/thumbnail now proxies a remote http(s) thumbnail_path
  server-side (same-origin, so dashboard CSP img-src is unaffected) via a non-throwing
  helper: upstream 404 -> 404, other failure/timeout -> 502, image/* only (modest SSRF
  hardening; the URL is server-set at ingest). Local thumbnails keep the sendFile path;
  the playlist/widget/workspace access gating is unchanged for both branches.
- routes/widgets.js inlineUserContent skips the disk read for a remote thumbnail and
  leaves the /api/content/:id/thumbnail reference in place (the proxy serves it).
- routes/content.js ingest unchanged; a comment notes the future download-at-ingest +
  backfill option for CDN independence.
- New test/thumbnail-proxy.test.js: local sendFile still works; a remote thumbnail is
  proxied (mock upstream, no local read, no ENOENT); upstream 404 -> clean 404. Full
  server suite 164/164.

* fix(server): boot banner shows the real version, not a hardcoded v1.2.0

The startup ASCII banner printed "ScreenTinker Server v1.2.0". Use the already-imported
VERSION (require('./version'), the single source of truth that reads the root VERSION
file) in a fixed-width field (VERSION.padEnd(22).slice(0, 22) — the same padEnd
discipline the port line uses) so the fixed-width box border stays aligned for any
version length. No other behavior changes.

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.

PiP overlay MVP: push image/web overlays to a device or group (#109) (#127)
* PiP overlay MVP: push image/web overlays to a device or group (#109)

Implements the #109 MVP from docs proposal: a floating overlay PUSHED to a device or
group in real time, rendered above the playlist without disturbing it. Scope is the
MVP only — video/RTSP, MQTT, offline-queue, and the priority/stacking system are
deferred to follow-up PRs as the proposal specifies.

Protocol (/device socket, player-agnostic):
- device:pip-show { pip_id, type:image|web, uri, position, width, height, duration,
  title?, title_color?, background_color?, opacity?, border_radius?, close_button? }
- device:pip-clear { pip_id? }
The player fetches uri itself (same trust model as remote_url content; server never
proxies). type:web is full-trust by design, hence the 'full' token scope.

Server (server/routes/pip.js, new; mounted in config/api-surface.js PUBLIC_ROUTERS):
- POST /api/pip and POST /api/pip/clear + DELETE /api/pip, all requireScope('full').
- Resolves device_id to a device OR a group, expands a group to members, and emits
  per-device — reusing the group command route's room-size online check and
  {device_id, name, status: sent|offline} result shape. Generates pip_id.
- Validates type/position allowlists, uri http(s), numeric bounds on
  width/height/duration/opacity/border_radius, colors via the existing VALID_COLOR
  (#RRGGBB; transparency is the separate opacity field).
- Workspace-isolated: every target query is scoped to req.workspaceId, so a token
  bound to workspace A can't address workspace B (404). Offline devices are reported,
  never queued (PiP is ephemeral).

Player overlay layer (Tizen; tizen/js/pip-overlay.js, new):
- A #pip sibling ABOVE #stage that PlaylistPlayer/ZoneRenderer never touch.
- applyOrientation now applies the SAME transform to #pip as #stage, so corner
  positions track the visible CONTENT in all four orientations.
- image -> <img>, web -> <iframe> (muted by default: empty allow= denies autoplay),
  sized/positioned/styled per payload, optional title bar.
- Single overlay slot, last-show-wins; duration timer (0 = until cleared); pip-clear
  (id-aware) or timer tears down; teardown wrapped so a malformed payload can't wedge
  the layer. Reports show/clear over device:log (tag 'pip').

Dashboard: a minimal "Send overlay" / "Clear overlay" tester on the device-detail
controls (device/group via the open device, type, uri, position, duration), calling
POST /api/pip through the api helper.

Tests (server suite green, 161/161):
- api.test.js: PiP tier — authz (read/write 403, full passes), workspace isolation
  (wsA token -> wsB device 404), payload validation, device + group targeting, clear;
  plus the PUBLIC_ROUTERS snapshot-firewall updated for /api/pip.
- pip-overlay.test.js: loads the real player.js + pip-overlay.js in a vm with a DOM
  shim; proves the overlay shows, auto-dismisses on the duration timer, and never
  changes the playlist signature / touches #stage; web->iframe, last-show-wins,
  id-aware clear, malformed-payload safety.

Not in this PR (intentional):
- Android player overlay — fast-follow. Protocol + server are player-agnostic; the
  Android layer (an overlay View above the player, orientation-matched to MainActivity's
  rootView rotation) is the same shape and lands next.
- OpenAPI docs for POST /api/pip — the contract test's scope heuristic only treats
  'command' paths as full-scope, so documenting a full-scope non-command route there
  needs that heuristic extended first; deferred with the docs item (proposal §8.6).
- video/rtsp types, MQTT, offline queue-on-reconnect, priority/stacking, arbitrary
  (x,y)/selector positioning (proposal §6).

* PiP overlay: add Android + web players (#109)

Extends the #109 PiP MVP to the other two players so the protocol (device:pip-show /
device:pip-clear) is honored fleet-wide, not just on Tizen. No server/protocol changes —
the route and socket messages are player-agnostic; these are the two missing surfaces.

Web player (server/player/index.html):
- New #pipContainer layer above #playerContainer, pointer-transparent, that the playlist
  render never touches. The same orientation transform is applied to it as to
  #playerContainer (extended to also reset width/height on landscape so a
  portrait->landscape switch realigns), so corner positions track the visible content.
- Inline PiP logic mirroring tizen/js/pip-overlay.js: image -> <img>, web -> <iframe>
  (muted by default via empty allow=), position/size/bg/opacity/radius/title, single slot
  last-show-wins, duration timer (0 = until cleared), id-aware clear, wrapped teardown.
- device:pip-show/clear handlers; reports show/clear over device:log (tag "pip").

Android player:
- activity_main.xml: a pipLayout FrameLayout as the LAST child of rootLayout — it draws
  above the content AND inherits rootView's orientation rotation/translation, so corner
  positioning is orientation-matched for free.
- PipOverlay.kt (new): builds the overlay box into pipLayout. image -> ImageView (decoded
  off-thread via ImageLoader, dropped if torn down mid-decode); web -> WebView with
  mediaPlaybackRequiresUserGesture=true (mute-by-default). Gravity-based corner/center
  placement with a 4% inset, GradientDrawable bg + corner radius, alpha=opacity, optional
  title bar. Single slot last-show-wins; duration timer; id-aware clear; teardown wrapped
  and also run on activity destroy (WebView cleanup).
- WebSocketService: onPipShow/onPipClear callbacks + safeOn handlers posted to the main
  thread (they build Views) + a sendLog(tag, level, message) emitter for device:log.
- MainActivity: instantiate PipOverlay (log -> wsService.sendLog("pip", ...)), wire the
  callbacks, tear down on destroy.

Verified: Android assembleDebug builds clean; web player inline JS parses; server suite
still 161/161 (no server changes this commit). Not yet validated on real hardware —
four-orientation corner positioning mirrors the player container/rootView transform but
should be eyeballed on a panel.

ScreenTinker 57d78dd1fa feat: full-screen-only guardrail for agency designations (#73)
Agencies can only be designated FULL-SCREEN playlists (no item with zone_id) - a full-screen
agency upload can't safely target a zone, so the ambiguous case is excluded rather than
solved. Checked at THREE points:
- Designation (tokens.js create + PUT /:id/targets) -> 400: reject a zoned target.
- Upload (agency.js item-add) -> 409: block if the playlist BECAME zoned after designation.
  MANDATORY because auto-publish has no draft net - a full-screen playlist designated to an
  auto-publish token, then zone-assigned, would otherwise auto-publish a full-screen upload
  into a zoned playlist. The upload check is the only thing that catches it.
- Picker (settings.js): zoned playlists greyed/disabled with the reason (GET /playlists now
  returns a zoned flag); backend reject is the guard if the UI is bypassed. i18n x5.

isZonedPlaylist = EXISTS(playlist_items WHERE zone_id IS NOT NULL). Pure restriction - no
zone structure, no api_token_target_zones.

Bite-test (the exact sequence) GREEN and re-proven to bite: full-screen -> designate to an
auto-publish token -> zone-assign the playlist -> agency upload is BLOCKED (409), not
auto-published; neutralizing the upload check makes it go red. 149 suite green.

ScreenTinker 4c38536cc6 feat(ui): edit-designations for agency tokens (#73)
Settings → API Tokens: each agency token gets an "Edit playlists" control that opens the
playlist picker pre-checked with the token's CURRENT designations (from the list GET's
tok.targets), lets the admin add/remove, and calls the existing PUT /:id/targets to
atomically re-designate. Reuses the creation picker pattern; common.save/cancel reused;
edit_targets + targets_updated i18n across all 5 locales. No security-model change - the
endpoint was already proven.

Test (integration): PUT /:id/targets re-designates (add + remove) and the confinement
follows the NEW set - a re-designated token reaches only its new playlists (router.param
403s the removed one). 148 suite green.

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 c5550f5bc9 feat: agency zone-grant issuance UI + reactive placement card (#73)
Issuance (on the proven seam):
- tokens.js create + PUT /:id/targets accept per-playlist zone grants (target_zones), inserted
  into api_token_target_zones inside the same transaction as the playlist grants (FK requires
  the parent, so order matters and is correct).
- Issuance validation (the mirror of runtime confinement): grantableZoneIds() - can grant ONLY
  a zone the playlist's layout actually feeds; can't grant one it doesn't have or one from
  another playlist's layout. Bite-tested. PUT re-designate stays atomic: delete parent rows ->
  zone grants cascade out (no manual child delete).
- settings.js: checking a designated playlist reveals its grantable zones (GET
  /api/playlists/:id/zones, JWT); leave unchecked = whole-playlist. i18n across all 5 locales.

Card:
- GET /api/agency/playlists/:playlistId/layout (rides router.param - confined; a non-
  designated playlist -> 403, asserted). "Your zone" = the GRANTED zones. Retired the
  token-wide /layouts (the per-playlist card replaces the disconnected lump).
- Portal card reacts to the playlist selector: pick a playlist -> its layout renders, the
  granted zone highlighted with px size, siblings as context.

Full suite + agency bite-suite green (154).

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 986d94a778 feat(api): GET /api/agency/layouts - device-free layout geometry (#73)
So the agency can size/place content: returns the canvas size + zone positions/sizes for the
layouts its designated playlists feed, marking which zones are theirs. DEVICE-FREE BY
CONSTRUCTION - the query path is playlist_items.zone_id -> layout_zones -> layouts and never
touches devices/groups/schedules, so device names/locations/IPs/topology are structurally
absent, not filtered. Geometry only - no sibling-zone content. layout.name included (admin's
canvas name); thumbnail_data omitted (could render other zones' content).

Confinement query in lib/agency-layouts.js, bite-tested: own layout YES, a non-designated
playlist's layout NO, response has NO device fields (asserted on a db where a location-named
device exists), and neutralizing the t.token_id filter goes red. 142 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.

The portal needs to show an agency which playlists it may post to. New read surface on the
security primitive, built with write-path rigor: the confinement query lives in
lib/agency-targets.js (own token + bound workspace only) and is bite-tested four ways -
own targets yes; another token's, outside the allowlist, and cross-workspace all NO;
neutralizing the t.token_id filter makes it go red. Real-path wiring + the portal's
graceful 401 trigger asserted in the integration suite. No :playlistId, so router.param
doesn't apply - the query is the seam.

ScreenTinker 40102b2b41 feat(api): agency portal endpoints + router.param target seam (#73)
The agency capability behind the proven off-ladder/agencyGate primitive:
- agencyGate is now SCOPE-only at the mount; the per-target check is router.param
  ('playlistId') in routes/agency.js - it fires WITH the param before the handler, so no
  :playlistId route can skip it (drift-proof). A mount-level target check was silently
  bypassed (Express populates req.params only at route match); the integration bite-suite
  caught it - this is the fix.
- routes/agency.js: POST /content (shared ingest) + POST /playlists/:id/items (date-bounded
  #74/#75 item; lands as draft so the admin's re-publish is the approval gate).
- tokens.js: issue scope='agency' tokens bound to a non-empty in-workspace playlist
  allowlist (atomic); PUT /:id/targets re-designates (JWT-only -> can't self-widen).
- server.js: AGENCY_ROUTERS mounted bearerAuth + resolveTenancy + agencyGate.

Full bite-suite (test/agency.test.js) GREEN and re-proven to bite on the SHIPPING path:
neutralizing the router.param check makes non-designated->403 go red. Four assertions at
three seams: target (router.param), off-ladder (tokenScopeGate), can't-widen (tokens
JWT-only), issuance cross-workspace (create validation). 139 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 f4c5865013 fix(server): strip totp_secret_enc/totp_last_step from login responses (#100)
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
Review caught the encrypted TOTP secret riding in the login/verify response body:
issueSession receives a SELECT * user row and only destructured out password_hash, so
totp_secret_enc (and the internal replay counter totp_last_step) leaked. Encrypted, so
not catastrophic, but it regresses the API work's "secrets never in responses" rule.
Strip both in issueSession (covers /login and /totp/verify); add an assertion that a
verify response carries no totp_secret_enc.
