GET /api/devices/:id/screenshot returns a live picture of what a screen is showing, but
it was still authorized pre-tenancy: `device.user_id !== user.id`, with a role bypass
listing 'admin'/'superadmin'. Three consequences, all now covered by tests:
- `device.user_id &&` SHORT-CIRCUITED. A device with no user_id — never paired, or its
owner deleted — skipped the ownership test entirely, so any authenticated account on the
instance could read it. An unpaired panel displays its pairing code on screen, so that
image is also a route to claiming the device (AUTH-10, out of scope here but connected).
- 'platform_admin' was absent from the bypass list. #14 renamed 'superadmin' to
'platform_admin', so an actual platform admin fell through to the ownership test and was
denied unless they happened to own the row.
- Workspace members other than the owner were denied a device they administer through
every other endpoint.
Now uses accessContext() against the device's workspace — the same helper routes/devices.js
uses — which covers direct membership, org-level access and platform staff in one call. A
device with no workspace is denied outright rather than defaulting open.
Deliberately unchanged: the ?token= query-parameter mechanism on this route, which is a
separate finding with its own blast radius.
No response shape change: still 200 / 401 / 403 / 404 with the same bodies.

Six places verified a session JWT inline instead of going through requireAuth,
each repeating a slightly different subset of its checks. Introduce
resolveSessionUser() in middleware/auth.js as the single definition of "this
token is a usable session, and here is whose it is", and route all of them
through it: the three /api/status token routes, the screenshot route, the
content-reference gate, and the /dashboard socket handshake. requireAuth is now
a thin wrapper over the same helper, so the two cannot drift.
Also:
- Give the pre-TOTP token a distinct audience so it is redeemable only through
verifyMfaPendingToken (POST /api/auth/totp/verify). verifyToken refuses any
token carrying an audience, so a token minted for one purpose cannot be
redeemed on another path.
- The dashboard socket handshake now takes userId/userRole from the live users
row rather than from the token claim, so role changes take effect on the next
connection instead of riding the token's remaining lifetime.
- Add test/session-token-resolution.test.js covering all six surfaces,
including the socket handshake.
Every call site keeps the status code and error body it returned before.
Net query cost: the content-reference gate and the socket handshake each gain
one users-by-id lookup (the same one requireAuth already does per request); the
other four are unchanged or replace an equivalent lookup.
In-flight pre-TOTP tokens are invalidated by the audience change; they live 5
minutes, so the window is a re-login at worst.

- Add Device modal now shows the server URL and full Smart TV player URL
- Smart TV note changed from bare /player to full URL (dynamic via JS)
- /download/apk error page now includes a download link to GitHub Releases
- i18n keys added in en + es, old smart_tv_note removed
Three features from this session, full server suite green (535/535).
TOTP 2FA (#100) — backend shipped without a UI; add it:
- Login: mfa_required -> 6-digit challenge (recovery codes accepted) -> /totp/verify.
- Settings > Account: enable (QR + confirm -> recovery codes once), regenerate,
disable; SSO accounts see "managed by your identity provider".
- /totp/setup returns a server-rendered qr_data_url (bundled qrcode dep). keyuri
folds the request Host into the issuer so multi-instance accounts are
distinguishable in the authenticator app.
Email verification on signup — hosted HARD-block / self-host SOFT-nudge:
- email_verified column; existing users asked on first login (SSO + platform
admins grandfathered); single-use 24h tokens (SHA-256 hashed).
- Gate engages only when email is configured (never locks out a no-mail instance).
GET /verify-email + POST /resend-verification (generic, no account enumeration).
- Client: "confirm your email" flow + resend, verified/error toasts, self-host
banner; onAuthSuccess refuses a tokenless response (defensive).
Tizen SSSP URL-Launcher install — Fusion-style one-URL native install:
- Server hosts /tizen/sssp_config.xml (dynamic <size>, always matches the served
.wgt) + /tizen/ScreenTinker.wgt + a human landing. lib/wgt-cache.js resolves the
signed .wgt (/data mount wins, mirroring the APK).
- build-wgt.sh also emits a static sssp_config.xml for CDN hosting.
- Retail panels require a Samsung Partner cert; dev-mode is SDB self-signed only.

Compositor panel-ring board scroll (smooth on Blink+Gecko, no blank-on-refresh), a per-device frame-rate diagnostic widget + dashboard card, and web/Android/Tizen device-id passthrough to widget render URLs.
Follow-up to #195. The CORP fix there landed on routes/content.js `/:id/file`, but that
handler is SHADOWED: server.js registers a public `app.get('/api/content/:id/file')`
(and `/thumbnail`) BEFORE the auth-gated content router, and that public route (gated by
playlist/widget reference) is what actually serves widget logo/background images. So the
header never changed on the wire — origin still returned CORP: same-origin and the player's
sandboxed (opaque-origin) widget iframe kept getting NS_ERROR_DOM_CORP_FAILED / 0 bytes.
Set Access-Control-Allow-Origin: * + Cross-Origin-Resource-Policy: cross-origin on the real
public routes in server.js: /file, /thumbnail (local), and the remote-thumbnail proxy.
Revert the now-dead content.js edit so the fix lives only where the bytes are served.

* feat(widgets): add directory-search widget
An interactive, walk-up search view of an existing directory-board. It
references a source board by id (no data copy), so a venue can run the
scrolling board on a main screen and a search view on a tablet, letting
people find an entry instantly.
Server (routes/widgets.js):
- register 'directory-search' + renderDirectorySearch(): resolves the source
board, inlines its categories as one \u003c-guarded JSON blob, renders all
text via textContent (XSS-safe), live case-insensitive filter over
identifier/name/subtitle (debounced), grouped results, available styling,
optional touch on-screen QWERTY keyboard that drives the same filter path.
- missing / non-directory-board source -> friendly full-page fallback, not a 500.
- live-sync while open is out of scope; left a // TODO for a poll hook.
Frontend editor (views/widgets.js): type + magnifier icon, source-board
dropdown (from loaded widgets, filtered to directory-board), title, logo
(reuses the board's picker), placeholder text, theme, on-screen-keyboard toggle;
getConfigFromForm case. i18n: widget.dirsearch.* + type keys in en/es/it/de/pt/fr.
docs: openapi widget_type enum. Tests: server/test/directory-search.test.js.

* feat(widgets): live-sync for directory-search (poll source board, no reload)
Reflect directory-board edits on an open directory-search page without a reload.
- New public GET /api/widgets/:id/data.json returns { categories } for a
directory-board (404 for missing/wrong-type so the page keeps last-good data
on a transient miss). CORS-open (ACAO:*) + no-store so a null-origin sandboxed
widget iframe can read it; exposes only data already public via /render.
Exempted from CSP + auth in server.js alongside /render.
- directory-search page inlines its source_widget_id and polls the board's
data.json every 30s via a relative URL (works behind a proxy/base path and
from a null-origin iframe). Only rebuilds + rerenders when the data actually
changed, so a mid-search view isn't disturbed; skips while document.hidden;
keeps last-good data on any fetch error. Flatten logic factored into
buildFlat() and reused by the poll.
Tests: data.json feed (categories, CORS header, 404s) + poll wiring in
directory-search.test.js (13/13). Verified live in a browser (page.clock
fast-forward): editing the board updates the search page with no reload.

* fix(android): let player WebViews take touch focus for interactive widgets
directory-search is served through the existing generic widget path
(loadUrl <server>/api/widgets/:id/render), so it already renders on Android
with JS + DOM storage + mixed-content enabled, same-origin (so its live-sync
fetch of the source board's data.json works), and no touch blocking.
Add isFocusable/isFocusableInTouchMode to the shared WebView config so the
search field reliably takes a tap/cursor inside the kiosk lock-task WebView.
Harmless for passive widgets (board/YouTube have no focusable inputs); the
widget's own on-screen keyboard still drives the filter when the system IME
is suppressed. Verified with :app:compileDebugKotlin.

Adds a pluggable email transport so self-hosters without Azure/M365 can send
mail through any standard SMTP server (Postfix, Gmail, Mailgun, SendGrid, corp
relay). Graph stays the default; behavior is byte-for-byte unchanged when
EMAIL_TRANSPORT is unset or "graph".
- config: EMAIL_TRANSPORT ("graph"|"smtp", default graph) + SMTP_HOST/PORT/
SECURE/USER/PASSWORD/FROM.
- services/email.js: branch by transport behind the SAME public sendEmail()/
isConfigured() surface. SMTP via nodemailer (lazy-required, like MSAL).
Shared across both transports: the "[ScreenTinker] " subject prefix (unless
rawSubject), the GRAPH_DEV_RESTRICT_TO allow-list, html-from-text derivation,
and the never-throws contract (failures log + return sent:false). SMTP_SECURE
true=implicit TLS(465)/false=STARTTLS(587). Auth optional (unauthenticated
relay ok); SMTP_USER without SMTP_PASSWORD is flagged. SMTP_FROM parses
"Name <addr>". New emailConfigStatus() for startup diagnostics.
- server.js: startup logs the transport and a LOUD error when the selected
transport is partially configured (some fields set, others missing) or when
EMAIL_TRANSPORT is invalid (falls back to graph). A fully-unset transport
stays a silent stdout fallback (unchanged dev behavior).
- nodemailer ^6.9.16 added as a production dep (bundled in the Docker image).
- .env.example + README: SMTP config section, Gmail example, transport table.
- test/email-transport.test.js: 15 tests — transport selection, config
validation (missing/partial/invalid), SMTP message building (from/prefix/
fromName override/text alt), sendEmail routing (mocked nodemailer), rawSubject,
dev-restrict on smtp, and the smtp_error never-throws path.
462/462 server tests pass. Boot verified for all four states (configured,
misconfigured, invalid, default).
Closes#173

express.static runs with index:false, so a bare /integrations/ fell through to the
SPA catch-all and rendered the dashboard login instead of the integrations hub — the
top-nav "Integrations" link, the canonical, and the sitemap entry all dead-ended at
login. Add an explicit route (like /agency, /sitemap.xml): /integrations/ -> the hub's
index.html, and /integrations -> 301 /integrations/. Spoke pages are real .html files
already served by static. Folded into a re-cut of v1.9.6.

* feat(dashboard): version indicator + GHCR update check with admin panel
- Add server/lib/ghcr-check.js: GHCR tag poller (36h cache, semver filter)
- Extend /api/version with latest_version and update_available
- Add POST /api/admin/check-update (force GHCR poll)
- Add POST /api/admin/trigger-update (Docker compose or manual instructions)
- Sidebar footer: version label + amber badge when update available
- Admin > System: version comparison card with Check/Update buttons
- 14 new tests (10 unit + 4 integration), 68/68 passing
Closes#163
* fix(dashboard): gate trigger-update to platform-admin + add GHCR fetch timeout
Review follow-up on #165 (the two blockers):
- trigger-update runs `docker compose up -d` on the HOST via docker.sock
(root-equivalent) but was behind requireAdmin, i.e. reachable by any
workspace-level admin. On a multi-tenant host that's a customer, not the infra
operator. Gate it with requirePlatformAdmin (DOCKER_UPDATE_ENABLED still gates
it further). check-update stays requireAdmin — it's a read-only GHCR poll.
- ghcr-check.checkNow had no fetch timeout. Node's global fetch has no default
timeout, so a hung GHCR connection never settled — leaving `inFlight` set
forever (the finally never ran), which wedged the background poller AND hung
any awaited checkNow (/api/admin/check-update). Add a 10s AbortController
timeout on both requests so the try/catch/finally always fire.
All 405 server tests pass.

Lets an operator (or an MDM) own updates instead of the app self-installing, which
on managed panels shows a self-install confirm dialog over customer content
(#155). Three layered controls:
- GLOBAL (server): config.otaEnabled from OTA_ENABLED (default on). When off,
/api/update/check returns update_available:false, reason:ota_disabled_global —
the whole instance stops offering updates.
- PER-DEVICE (server + dashboard): new devices.ota_enabled column (default 1). When
0, that device is never offered an update (reason:ota_disabled_device). A
"Self-update (OTA)" toggle in the device settings flips it via PUT /api/devices/:id.
- AUTO-DETECT (Android): UpdateChecker stands down entirely when a foreign device
owner (an MDM/DPC) manages the panel — detected via getActiveAdmins() + not being
device owner ourselves. Pure client-side, errs safe, needs no server change.
The two server gates are enforced server-side so they cover EVERY client version,
not just ones with the client-side stand-down. When OTA is off the device still
reports its version (dashboard sees state); the MDM/operator owns the actual update.
For an MDM-managed fleet (e.g. Pivot/MAXHUB), turn OTA off and let the MDM push the
APK — the install-dialog race disappears from every angle.
Tests: +2 (per-device gate + a real OTA_ENABLED=false server for the global gate);
full server suite 393 pass; Android compiles.

- Remove stray brace that broke compilation (MainActivity line 985)
- Server generates unique 6-digit PIN per device during pairing
- PIN stored in encrypted SharedPreferences (ServerConfig.settingsPin)
- Fallback: generate random PIN locally if server doesn't send one
- Include settings_pin in device:paired on pair + reconnect
- DB migration: settings_pin column on devices table
- Hint changed from hardcoded 0000 to generic 'PIN' string
* fix(preview): replace srcdoc with server-side preview sessions to bypass CSP
Widget previews (clock, weather, etc.) were rendered via iframe.srcdoc,
which inherits the dashboard CSP script-src 'self'. This blocked the inline
scripts widgets need (setInterval for clock, fetch for weather), causing
previews to show blank/static content.
Replace srcdoc with ephemeral server-side preview sessions:
- POST /api/widgets/preview-session — stores rendered HTML (Map, 5min TTL)
- GET /api/widgets/preview-session/:id — serves the HTML via iframe src,
bypassing CSP like the device render endpoint already does
The old /api/widgets/preview endpoint is unchanged for backward compat.
* fix(preview): add rate limiter for /preview-session route

The dashboard CSP (script-src 'self') blocked Cloudflare's Web Analytics beacon. Add the two exact
entries the beacon needs (both required — script-only loads but silently can't report):
- script-src: https://static.cloudflareinsights.com (beacon script loads)
- connect-src: https://cloudflareinsights.com (beacon POSTs analytics back)
Exact domains, no wildcards. connect-src already had 'wss:'/'ws:' (socket.io) + 'https:' — those stay,
so the dashboard socket is unaffected; the explicit CF domain documents intent and survives any future
tightening of the broad 'https:'.

Disable wal_autocheckpoint on the main connection; run PASSIVE checkpoints from a
worker_threads worker with its OWN better-sqlite3 handle, escalating to TRUNCATE on a
size high-water or PASSIVE-starvation. Removes the synchronous fsync-heavy checkpoint
from the event loop. Config: walCheckpointIntervalMs/HighWaterMB/StarvationRuns.
Local only — no bump/tag.
Field-safe SERVER net. A device opening duplicate/rapid sockets (the APK duplicate-socket bug,
separate track) currently churns through evictions during the reconnect-throttle's 30s
post-restart WARM-UP (only the hard ceiling 20 applies then, so an 8-in-9s burst passes
undamped and each new socket evicts the prior). This makes the server absorb it: a thrashing
PAIRED device converges to ONE stable connection and stays online.
- lib/session-settle.js (decision only; bounded, swept): shouldHold(deviceId, incumbentAlive)
— true only when a socket was accepted for this device within SESSION_SETTLE_WINDOW_MS
(config, default 2500ms) AND the incumbent is alive. Warm-up-independent.
- deviceSocket register gate (just before evictPriorSocket): if a LIVE incumbent exists and
we're inside the window, SOFT-REFUSE the new socket (device:throttled reason=session_settle
+ disconnect) and keep the incumbent; else accept + evict + (re)arm the window.
- LIVENESS SAFEGUARD (load-bearing): only hold when the incumbent socket is actually in the
/device namespace — a dead/half-open incumbent is replaced, NEVER stranding the device (max
hold is the 2.5s window from the incumbent's accept, then any new socket is accepted).
- Soft refusal, NEVER a quarantine (reuses patch1's paired-safe philosophy); single-session
enforcement intact for a legitimate move; unpaired/abusive flapping still caught by the
existing limiters. O(1), no loop impact.
Tests (liveness first-class): live incumbent holds + DEAD incumbent replaced (not stranded);
storm of 6 sockets converges to ONE, stays online, not quarantined (during warm-up); single-
session move past the window replaces cleanly; unit decision + bounded sweep. The
evicted-socket-rearm test shrinks its settle window so it still exercises the eviction path.
Suite 336/336.
Item 2: when the heartbeat checker marks a device offline it now also disconnects any socket
it still holds for it, so DB-offline can't diverge from socket-state into a silent half-open
(defensive — the live-socket guard already defers genuinely-live sockets).
Item 3: tighten half-open detection WITHOUT reintroducing the TV-WebKit decode-load risk the
30s pong-timeout was chosen for — lower only pingInterval 30s->15s (probe more often), KEEP
pingTimeout at 30s. Detection = interval+timeout = 45s (was 60s), and the client inherits
these via the handshake so BOTH ends detect a dead peer ~25% sooner. (Deliberately did NOT
drop pingTimeout to ~20s: MAXHUB is a video-playing TV-class device and the code comment
warns tighter timeouts cause spurious drops under decode load.)
Item 4: SO_KEEPALIVE on every accepted connection (lib/tcp-keepalive.js) so a half-open TCP
can't persist indefinitely at the OS layer, independent of the app ping.
Tests: server closes a non-ponging peer within ~pingInterval+pingTimeout while a ponging peer
survives; a device whose transport dies ends offline with its connection torn down; keepalive
applied to each accepted connection (and never breaks setup on error). Suite 328/328.
ROOT CAUSE (hypothesis A, pre-existing — NOT a beta7 regression; server/player/index.html
is untouched since v1.9.2-beta6): handlePlaylistUpdate's "Playlist unchanged" branch blindly
returned. The media re-attach (renderContent) lives ONLY in the content-changed branch, so
if the <video> surface was lost (element detached from the DOM while still decoding — video
gone, audio still playing) a no-new-content refresh never re-attached it. New-content
refreshes were fine because they re-render.
FIX (make the refresh idempotent for the media surface, no flicker on the healthy path):
- server/lib/player-media-health.js (new, UMD + unit-testable, mirrors schedule-eval.js):
needsReattach(state) — re-attach ONLY when playback should be happening but the current
item's surface is actually lost (video null / detached / ended / errored; non-video: no
mounted surface). A healthy attached+live video returns false, so a routine poll stays a
no-op (no re-render, no flicker). Served at /player/player-media-health.js from the single
source; loaded by the player.
- index.html no-change branch: extract the current item's DOM facts and, iff
PlayerMediaHealth.needsReattach, call playCurrentItem() to re-render the current item.
Wrapped so the health check can never break a refresh.
- teardownCurrentMedia: also release currentVideoEl even when it was DETACHED from the
container — a detached-but-playing <video> keeps emitting audio and the container-scoped
querySelectorAll can't find it. This kills the "ghost audio" on re-attach.
- sw.js cache bumped v9 -> v10 so players pick up the new index.html + module.
Tests: test/player-media-health.test.js (6) exercises the branch selection — healthy video
-> no re-attach; detached/null/ended/errored -> re-attach; idle -> never; non-video by
surface presence. Inline player JS syntax-checked; module served + referenced verified on a
booted server. Suite 316/316.

Least-privilege way to read GET /api/billing/usage without requiring platform admin.
Additive + isolated: reuses the existing api_tokens scope system (the off-ladder 'agency'
scope is the precedent) and does NOT touch the shared role/permission checks other
endpoints rely on.
- New off-ladder scope 'billing:read' (routes/tokens.js SCOPES). Like 'agency' it is NOT
on the read<write<full ladder, so tokenScopeGate rejects a billing token on every
PUBLIC_ROUTER and JWT-only routers reject any st_ token -> the scope grants billing-read
and NOTHING else.
- DUAL-PATH gate requireBillingRead (middleware/apiToken.js), written as an EXPLICIT OR:
authorize if (billing:read token) OR (platform-admin session). Admins keep read access
but are NOT required to; the token path doesn't lock out admins or vice versa. Billing
route now mounted with bearerAuth (token OR JWT front door) + requireBillingRead (was
requireAuth + requirePlatformAdmin).
- MINTING is platform-admin only (stricter than read/write/full/agency, which any
workspace member may mint) since a billing:read token grants GLOBAL billing-read. Note:
no finer "owner" tier exists here (#14 collapsed superadmin->platform_admin), so
PLATFORM_ROLES is the top level required.
Tests (5, test/billing-authz.test.js): dual-path positive (token AND admin session both
200) + negative (user 403 / anon 401); scope isolation (billing token 403 on /api/devices,
401 on /api/admin; read token 200 on devices but 403 on billing); minting owner-only
(user + ordinary-admin 403, platform-admin 201); revocation -> 401. Existing token
firewall/partition suite (api.test.js) + billing-endpoint tests unchanged & green. Reused
the exact SHA-256 token-verification path (no bcrypt/new mechanism). Suite 306/306.
NOTE: spec described bcrypt + JSON `scopes` + an analytics:read precedent; this codebase
actually uses SHA-256 + a single `scope` TEXT column + 'agency' as the off-ladder
precedent. Implemented faithfully to the real system.

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.

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.

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.

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.

/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.

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.

Devices that download an OTA APK but cannot silently install it (Fire TV: no
device-owner path) re-downloaded the full APK every check cycle indefinitely -
install never completes, version never advances, next check re-triggers.
Client (UpdateChecker.kt, ServerConfig.kt, OtaThrottle.kt):
- Reuse a cached, signature-verified APK instead of re-downloading every cycle;
delete leftover invalid files; keep the verified APK on disk as the
manual-install artifact.
- Persisted per-version attempt budget (EncryptedSharedPreferences) so it
survives the Fire OS app restarts that drive the loop. An attempt is counted
only when an install is launched - a download/verify failure does not consume
the budget, so a transient network problem cannot park a healthy device in
backoff. After 3 failed installs, back off to one retry per 24h.
- Clear OTA state and caches when a check returns update_available=false while
state is pending (app relaunched as the new version).
- Report OTA status to the dashboard via device:log (tag ota) on state
transitions only (enter-backoff, clear) to avoid flooding the channel.
- Extract throttle decision logic into a pure OtaThrottle object (no Android
deps) with JUnit coverage (OtaThrottleTest) for the state transitions.
Server (server.js):
- Reword /download/apk log from "OTA update in progress" to "APK served" and
rate-limit to once per IP / 10 min so a looping device cannot flood the log.
Note: client-cooperative fix - prevents the loop in cohorts running this APK.
Currently-stuck beta4 devices still require a one-time manual update.

* 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.

A FK constraint violation crashed the whole process on 1.9.1-beta2 with a
bare "FOREIGN KEY constraint failed" and NO stack — so it couldn't be root-
caused. better-sqlite3 is synchronous, so such a throw inside a socket.io
handler (no local try/catch) propagates to uncaughtException, and with no
handler Node exits traceless.
Add a small top-of-server.js net that logs the FULL err.stack (file:line of
the offending write) + timestamp, best-effort closes the DB (WAL flush), then
exits(1) so systemd restarts fresh. NOT catch-and-continue — after an uncaught
throw the process state is undefined, so we never keep serving. This is the
investigation tool the root-cause fix is blocked on, plus the fleet-wide-crash
net #114 asked for.
Verified (not assumed):
- A synthetic synchronous FK throw inside a real socket.io handler IS caught by
uncaughtException, logs the full stack incl. the throwing file:line, exits 1.
- Non-over-reach: a FK throw in an Express route -> Express handles it (500), a
throw in a local try/catch -> caught (200); the global net does NOT fire and
the process stays alive. Last resort, not a catch-all.
- 149 server tests green; server boots clean (net doesn't trip on startup).
The root-cause FK fix is SEPARATE and waits on the stack trace this produces.

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.

Agency-facing. A self-contained page at /agency (NOT the dashboard SPA - the agency has no
JWT, only the token). Entry: paste access key -> sessionStorage (cleared on tab close, not
localStorage) -> sent as Bearer. Flow: list designated playlists -> upload (shared ingest =
first-class content) -> date-bounded item on a chosen playlist (lands as draft for admin
re-publish). Graceful failure: any 401/403 resets to the entry screen with "key invalid,
paste it again" - never a wall of 403s. Blast radius of a leaked key stays bounded by the
narrow scope.

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.

app.use('/api/auth/login', rateLimit(...)) etc. keyed on req.path, which Express strips to
'/' for mounted middleware - so /login, /register, /totp/verify shared ONE per-IP counter
(coupled limits; the new /totp/verify brute-force limit was not actually independent). Key
on originalUrl instead. Also adds the /api/auth/totp/verify 10/min limit (tightening #2).

The OTA was invisible server-side: /api/update/check and /download/apk returned without
logging, which is part of why the 1.9.0 auto-relaunch failure went unseen. Log every
version check (client version vs latest, update_available, whether an APK is staged) and
every APK download (a device actually applying an OTA), keyed on the CF-aware getClientIp
so production logs show the real per-device IP behind Cloudflare, not the edge.
Observability for the #96 auto-relaunch work (this is how we'll watch the OTA fire during
the relaunch testing). Part of #96.

The 6-digit pairing code is generated client-side, so the server can't raise its entropy
without a player change. Instead, harden server-side (no client change):
- lib/pair-lockout.js: lock an IP out of POST /api/provision/pair after 5 failed claims
(15-min lockout), and expire stale provisioning codes after 15 min so a code is not
claimable indefinitely. A successful claim resets the IP.
- /pair enforces both. Only an UNKNOWN code (404) counts toward the lockout (a real guess);
an EXPIRED code (410) is a legitimate-but-stale code and does NOT count, so a slow bulk
rollout from one shared-NAT IP can't lock itself out. getClientIp is Cloudflare-aware
(CF-Connecting-IP validated against a trusted edge peer), so the lockout keys on the real
per-client IP, never a shared edge.
Unit-tested deterministically with injected time, incl. the bulk-rollout-never-locks case.

- docs/openapi.yaml: the public, token-reachable surface only, with the auth model
(Bearer st_) and a per-operation x-required-scope (read<write<full). JWT-only routers
are excluded by design.
- Serve /openapi.yaml + /docs (Redoc via a vendored standalone bundle, no CDN so it
works air-gapped; /docs is CSP-exempt). docs/ is bundled into the release tarball.
- CI: redocly lint + a public-only guard that fails loudly if a JWT-only path ever leaks
into the spec.

Introduce the public API's token layer and make the router partition data-driven.
- api_tokens table: SHA-256 hashed secret, st_ prefix, workspace-bound, read/write/full scope.
- middleware/apiToken.js: bearerAuth front door (Bearer st_ -> token auth, else the
unchanged requireAuth); apiTokenAuth acts as the owner with platform powers stripped
to 'user' and the workspace binding made authoritative (X-Workspace-Id ignored);
tokenScopeGate (read=GET, write=mutations) + requireScope('full') for commands.
- config/api-surface.js: single source of truth for the PUBLIC (token front door) vs
JWT-ONLY (requireAuth) router partition. server.js mounts from these lists so the
mount list and the partition firewall test cannot drift.
- device-groups: operational group commands (reboot/shutdown) require the full scope.
A Bearer st_ token fails jwt.verify on the JWT-only routers (401), so privileged
surfaces (admin, workspaces, ai, provision, white-label) are unreachable by exclusion.

POST /api/provision (the routes/provisioning.js router endpoint) pairs a device
by pairing_code with no rate limit - the limit at server.js:287 was bound only to
the /api/provision/pair override. An authenticated user could brute-force 6-digit
pairing codes against the bare endpoint to claim devices in the unclaimed pool.
Bind the rate limit to the /api/provision mount so it covers both pairing paths.
Verified: 6 rapid POSTs to /api/provision now 429 on the 6th (was unlimited);
/api/provision/pair still 429s on the 6th.

Each playlist item can carry schedule blocks (active days, start/end
time-of-day, optional start/end dates). An item plays when the screen's
local "now" matches at least one block; an item with no blocks always
plays. #74 covers time-of-day/day-of-week windows including overnight
wrap; #75 covers inclusive date ranges (auto-expiry). Evaluation is
on-device, so dayparting and expiry work offline.
- Shared evaluator contract: shared/schedule-vectors.json (39 vectors —
DST US+AU, overnight-wrap anchoring, timezone correctness, date
boundaries). Canonical JS evaluator in server/lib/schedule-eval.js;
Kotlin and Tizen ports kept in lockstep by drift guards (Tizen byte-diff
test, Kotlin JUnit reads the shared JSON, new android-test CI job).
- All three players (web, Android, Tizen) filter by schedule against their
own clock, idle with a "Nothing scheduled" message + 30s re-check when
everything is filtered, and fail open on any evaluator error.
- Editor: per-item schedule modal + row badge in the playlist editor;
client validation mirrors the server; editing marks the playlist draft.
- Part B (behaviour change): device/group schedule overrides now evaluate
in each device's effective timezone instead of server-local time.
- Device detail shows the reported timezone + a clock-skew warning.
- i18n for en/es/fr/de/pt across all new strings (namespaced itemsched.*
to avoid colliding with the device-schedule calendar's schedule.*).
- CHANGELOG documents the feature, the Part B change, the fail-open
guarantee, and the scheduled-single-video re-render tradeoff.

A never-visited org had no cached white-label, so brand-prime fell through to the
ScreenTinker default baked into the static index.html and flashed it before
branding.js fetched the org brand. Now the /app route injects the resolved
instance / custom-domain branding into the shell as a <meta name="ssr-brand">
(CSP blocks inline <script>, so a meta carries it), and brand-prime applies that
as the fallback when the per-workspace brand is not cached yet - so the page
paints the configured brand on first load instead of ScreenTinker.
- server.js: /app resolves branding (publicBranding strips internal columns) and
injects the HTML-escaped JSON as a meta tag; falls back to plain sendFile on
any error so branding can never break the app shell.
- brand-prime.js: read meta[name=ssr-brand] when there is no rd_branding_<ws>.
Verified: the meta carries the resolved brand (default ScreenTinker and a
platform-default white-label), internal columns do not leak, 66 unit tests pass.

- .github/workflows/release.yml: on a v* tag - verify the tag matches VERSION
(fail-fast guard), run tests, build a source tarball + the unsigned Tizen .wgt
and publish a GitHub Release with generated notes, and build+push a multi-arch
(amd64 + arm64) image to ghcr.io/screentinker/screentinker:<version> + :latest.
The Release (artifacts) and the docker push are independent jobs, so an
arm64/QEMU docker failure does not block the GitHub Release and is re-runnable.
Nothing deploys to prod. APK-build-in-CI left as a TODO (keystore secret).
- Dockerfile + .dockerignore: multi-stage node:20-slim image with server +
frontend + VERSION + scripts; DATA_DIR=/data volume for db/uploads/jwt-secret.
Verified to build, boot, serve the dashboard + web player, and persist state.
- docker-compose.example.yml: /data volume, SELF_HOSTED, a node-fetch healthcheck
against /api/status, and an admin-lockout recovery note (reset-admin.js).
- server.js: resolve the OTA APK from DATA_DIR first (a container can mount one
at /data/ScreenTinker.apk), fall back to the legacy in-repo path, 404 gracefully.
- ci.yml: bump checkout/setup-node to v6 (clears the Node-20 action deprecation).

- 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.

A prompt now produces a full sign: the LLM writes the design AND image prompts,
the server generates the images and composites them with the crisp text layer.
- lib/image-gen.js: text-to-image with 3 BYO/self-hostable backends, all behind
the SSRF guard: 'sdcpp' (local stable-diffusion.cpp OpenAI-compatible server,
exact small sizes that fit VRAM), 'openai' (cloud / OpenAI-compatible, snapped
sizes), 'comfyui' (prompt/history/view API).
- ai.js: prompt asks for a background_prompt (preferred — full-bleed atmosphere)
and an optional foreground image element; after the design is normalized, the
bg + fg images are generated best-effort (a failed image never fails the sign)
and returned as data URLs. New image_* settings (provider/base_url/model),
image_provider whitelist, schema column + migration.
- designer.js: AI-images section in settings; generate applies the background
image; publish bakes the background image into the HTML so it survives.
- server.js: raise JSON body limit to 12mb for embedded image data URLs.
Verified end-to-end on local Vulkan SDXL (RTX 5090): prompt -> bg+fg images on
the canvas -> publish creates a widget with the images embedded. 63/63.
Note: prod (not self-hosted) requires a PUBLIC image endpoint (e.g. OpenAI); the
SSRF guard blocks localhost there. Follow-up: upload generated images to the
content store and reference by URL to avoid multi-MB widget configs.
Competitor pressure (Mandoe 'AI Magic Create'): prompt -> signage. We answer it
in a way that's actually BETTER for signage and costs the operator nothing.
Key idea: don't generate raw images (AI garbles text - fatal for menus/promos).
The LLM returns a STRUCTURED design spec (headline, supporting text, accent
shapes, palette) that the existing Designer renders with real fonts - crisp and
fully editable. Reuses the whole Designer.
BYOK, fully under the customer's control: each workspace configures its own
OpenAI-COMPATIBLE endpoint + key - OpenAI cloud OR self-hosted (Ollama / LM Studio
/ llama.cpp). Operator bears zero AI cost/liability.
- server/lib/secretbox.js: AES-256-GCM for the key at rest (never returned).
- routes/ai.js: GET/PUT /api/ai/settings (admin; key write-only) + POST
/generate-design (editor+). Output is strictly validated/normalized (cap count,
clamp ranges, px->%, strip HTML, validate colors) - never trust the model.
SSRF guard: hosted instances block private/internal targets; self-hosted (the
whole point of local AI) may point at localhost/LAN.
- Designer: an 'AI generate' panel (prompt + Generate) + a settings modal.
Verified end-to-end against local Ollama (llama3.1:8b): prompt -> editable design
on the canvas. Unit tests cover normalization + the SSRF guard. Suite 61/61.
Phase 2 (next): AI background images (OpenAI images / AUTOMATIC1111).
After uploading, content thumbnails were blank until the item was added to a
playlist/widget. The public /api/content/:id/thumbnail (and /file) endpoints are
reference-gated (an anonymous player with a UUID must not pull arbitrary tenants'
media), and a plain <img> can't send a Bearer token - so a just-uploaded item 403'd.
- Backend: add an authenticated bypass - a logged-in user who can access the
content's workspace (verified from the Bearer token) may view its file/thumbnail
even when unreferenced. Anonymous players still hit the reference gate.
- Frontend: the content library lazy-fetches thumbnails/previews WITH the token
and swaps in an object URL (IntersectionObserver keeps it under the rate limit;
the URL is revoked after load).
Verified: unreferenced thumbnail now 200 with a bearer token, still 403 anonymous.
