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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

#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).

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).

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.

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.

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.

Opt-in, default-off UI gate (per strobe's spec; verified his file refs first).
When set, hides the Subscription sidebar item + billing view and bounces
#/billing to the dashboard. Billing shown by default -> existing deployments
unchanged. UI-only: /api/subscription/* untouched (internal usage reads stay).
- config.js: config.hideBilling from HIDE_BILLING (mirrors selfHosted).
- auth.js: surface hide_billing on GET /api/auth/me (client already fetches it
at boot, stored on the user object).
- index.html: id="billingNavItem" on the Subscription <li> (mirrors adminNavItem).
- app.js: toggle billingNavItem in updateSidebarUser (next to the admin toggle);
guard #/billing -> history.replaceState('#/') + render dashboard (replaceState
so the back button doesn't loop into the guard).
- .env.example + README documented.
Spec assumptions verified against code: adminNavItem toggle pattern exists;
/me is fetched at boot and updateSidebarUser runs both at boot (cached user)
and post-/me, so no-flash holds on warm loads (one-time flash possible on the
first load after the flag flips — same as the admin nav, minor); route dispatch
is an if/else chain. Nav label is static (no data-i18n) so no i18n change.
Validated (headless Chrome, both states):
- flag unset -> Subscription tab present, #/billing renders (backward-compat).
- HIDE_BILLING=true -> tab hidden, #/billing redirects to #/.
- config maps HIDE_BILLING both ways; live /me default hide_billing=false.
- 149 server tests green. Default-off = zero change for existing deployments.
Known cosmetic (harmless): after the redirect the billing nav LINK keeps its
'active' class, but the nav item is display:none so it's never visible.

- server/version.js: shared version helper that reads the root VERSION file once
(fallback 0.0.0). Replaces the stale hardcoded 1.2.0 / 1.5.1 / 1.0.0 fallbacks
in /api/version, /api/update/check, and /api/status.
- config.js: DATA_DIR / DB_PATH / UPLOADS_DIR / CERTS_DIR env overrides for the
db, uploads, and certs/jwt-secret locations. Unset resolves to exactly the
legacy in-repo paths, so existing installs (including production) are
byte-for-byte unchanged. Guarded by test/config-paths.test.js.
- package.json: rename remote-display-server -> screentinker (+ lockfile name).
- scripts/bump-version.sh: one-shot bump across VERSION, package.json (+lock),
android (versionName and versionCode + 1), and the tizen widget version; makes
one commit plus an annotated tag; prints the push command, never pushes.
- .gitignore: global *.db / *.db-wal / *.db-shm / *.db.* so no database file
(including .db.devbak backups, at any path) can be committed.

MSP-style deployments want self-service signups created WITHOUT a personal
org, so an admin/operator can assign them into an existing customer org
afterward.
- config.autoCreateOrgOnSignup (AUTO_CREATE_ORG_ON_SIGNUP env), default
true - single-tenant and the hosted self-service flow are unchanged.
- ensureDefaultOrgForUser gains { allowCreate }: an existing membership is
always returned (idempotent); the MINT path is gated. allowCreate=false +
no membership -> returns null (user created org-less).
- register accepts a per-request createOrg flag overriding the deployment
default; the first-ever user is always given an org (never headless).
login / Google / Microsoft pass allowCreate from the global config, so an
org-less user is not silently given an org on next sign-in.
Edge case: a non-platform user with zero workspaces now lands on a "no
workspaces yet" empty state (new no-workspace view) instead of being bounced
into onboarding (whose pairing step needs a workspace). route() redirects
them there, and refreshCurrentUser() redirects once /me reveals zero
accessible_workspaces (covers the first-load race). The workspace switcher
already rendered an empty placeholder and resource routes already return []
for a null workspace, so nothing crashes in between.

Short-lived per-device queue covers the TV-flap window (issue #3):
when a device is mid-reconnect, prior code emitted to an empty room
and the event vanished. Now playlist-updates and commands targeting
an offline device are queued and flushed in order on the next
device:register for that device_id.
server/lib/command-queue.js (new):
- pendingPlaylistUpdate: per-device marker (rebuild via builder on
flush -> always fresh DB state, no stale snapshots)
- pendingCommands: per-device Map<type, payload> with last-of-type
dedup (most recent screen_off wins)
- TTL via COMMAND_QUEUE_TTL_MS env (default 30000)
- Active sweep every 30s prunes expired entries
Memory bounds: ~6 entries per device worst case (1 playlist marker
+ 5 command types), unref'd sweep timer.
Wired emit sites (8 total; the four direct socket.emit calls in
deviceSocket register handlers are intentionally NOT queued because
the socket is alive by definition at those points):
- server/routes/video-walls.js (pushWallPayloadToDevice)
- server/routes/device-groups.js (pushPlaylistToDevice)
- server/routes/content.js (content-delete fan-out)
- server/routes/playlists.js (pushToDevices + assign)
- server/services/scheduler.js (scheduled rotations)
- server/ws/deviceSocket.js x2 (wall leader reclaim/reassign)
server/ws/deviceSocket.js register paths now call flushQueue after
heartbeat.registerConnection + socket.join. Existing
socket.emit('device:playlist-update', ...) lines kept - they send
the initial state on register; the flush replays any queued events.
Player's handlePlaylistUpdate fingerprint check dedupes the
overlap.

Make HEARTBEAT_INTERVAL and HEARTBEAT_TIMEOUT env-tunable so
self-hosters with slow/jittery networks don't have to edit
config.js (issue #3 reporter did exactly this to confirm the
diagnosis). Defaults unchanged at 10000ms / 45000ms so existing
deployments keep current behavior.
Same parseInt(env) || default pattern as PORT/HTTPS_PORT/PING_*.
README env table extended.

Connection-stability layer for issue #3. LG webOS WebKit (and other
TV-grade clients) miss Engine.IO pongs under decode load with the
Socket.IO defaults of 25s ping / 20s timeout, causing spurious
transport drops and a connect/reconnect/evict/disconnect loop on
the device. Default polling-first transport adds another fragility
layer via the polling->WebSocket upgrade dance.
- pingInterval / pingTimeout default to 30000 / 30000 (worst-case
dead-socket detection 60s, up from ~45s). Both env-configurable
via PING_INTERVAL / PING_TIMEOUT.
- Player Socket.IO client: transports: ['websocket', 'polling'].
Tries WebSocket first; falls back to polling on the same connect
attempt if WebSocket fails. Polling fallback preserved for
firewall-restricted networks.
App-level heartbeat checker is unchanged and remains the safety net
for clients that miss the transport-level ping/pong window.
Tradeoffs documented in inline comments. README env table extended
with PING_INTERVAL and PING_TIMEOUT rows.

Self-hosters running internal-only deployments don't need the
marketing homepage. With DISABLE_HOMEPAGE=true, requests to /
302-redirect to /app instead of serving the landing page.
Unset/false preserves current behavior.

Replaces the unused EMAIL_WEBHOOK_URL stub with a real Microsoft Graph
Mail.Send pipeline via @azure/msal-node client-credentials flow. Prior
state on prod: every alert email was logged to journalctl and never
sent (21 fallback log lines per hour for the chronic-offline devices).
Four coordinated changes shipped as one commit since they're all part
of making email delivery actually work responsibly:
1. services/email.js (NEW): Graph send via plain HTTPS (no SDK), in-memory
MSAL token cache (refresh 60s pre-expiry), graceful stdout fallback
when GRAPH_* env vars absent. Drop-in replacement for the old webhook.
2. services/alerts.js refactored: sequential await around sendEmail (was
parallel fire-and-forget; first run hit Graph's MailboxConcurrency 429
ApplicationThrottled on a 30-device backlog). Sequential at ~250ms per
send takes 5-8s for the full backlog, well within the 60s tick. Also:
24h long-offline cutoff to stop nagging about chronic-offline devices
(the 20,000+ minute ones); 2-hour dedup window (was 1h) via a generic
shouldSendAlert(type, id, windowMs) helper that future alert types
(payment_failed, plan_limit_hit, etc.) can reuse.
3. Preferences UI: single checkbox in settings.js Account section bound
to users.email_alerts. Saved via the existing Save Profile button. PUT
/api/auth/me extended to accept email_alerts. requireAuth middleware
SELECT now includes email_alerts so it propagates via req.user.
4. Dev safety net: GRAPH_DEV_RESTRICT_TO env var as an allow-list. When
set, only listed recipients reach Graph; everyone else is suppressed
with a log line. Prevents local dev (which often runs against fresh
prod DB copies) from accidentally emailing real prod users. UNSET on
prod systemd unit so production fans out normally.
Also: package.json scripts use --env-file-if-exists=.env so local dev
picks up .env automatically (Node 20.6+ built-in, no dotenv dep). Prod
runs via systemd ExecStart and is unaffected. server/.gitignore added
to keep .env out of git.
Smoke verified end-to-end:
- Sequential send pattern verified (a prior parallel-send tick had hit
Graph's MailboxConcurrency 429 on 30 simultaneous sends; sequential
at ~250ms each completes the same backlog without throttling)
- 24h cutoff silenced 20/21 prod devices on the next tick
- Dev restrict suppressed the 1 within-24h send
- User-preference toggle flipped via UI -> DB -> alert path silently
continued before reaching even the suppression log
When DISABLE_REGISTRATION=true (or 1), POST /api/auth/register returns
403 with a clear error. OAuth endpoints (/google, /microsoft) also
refuse to auto-create new accounts — existing OAuth users can still
sign in. First-user setup (empty users table) is always allowed so a
fresh install can still be initialized.
GET /api/auth/config now returns registration_enabled so the login
view can hide the "Create Account" button and the trial banner when
registration is off. Absence of the flag is treated as enabled for
back-compat with older servers.
