ScreenTinker 0030acc526 Store a schedule in the timezone its screen runs in
Creation and playback disagreed about which clock a schedule's hours are on.
The player evaluated blocks in the device's zone — an operator override, else
whatever the player's OS reported. Creation defaulted to a bare 'UTC', because
the dialog never asked for a zone and the server filled the silence with one.

So hours typed as "09:00 to 17:00" were stored as UTC and evaluated somewhere
else. For anyone outside UTC the schedule was correct and appeared to do
nothing, opening hours later than intended, with nothing on screen to explain
why. A user in Asia/Tokyo hit exactly this and reported it as "I added
something and it didn't appear".

Both sides now resolve through lib/device-timezone, so they cannot drift: an
explicit device override wins, then the OS-reported zone, then null. A legacy
'UTC' override counts as unset, since that was the old default rather than a
deliberate choice and a genuine UTC deployment is indistinguishable from an
unconfigured one.

A new schedule inherits its target's zone — the device's, or for a group its
leader's, falling back to the oldest member that reports one. A zone named
explicitly by the caller still wins; this only fills the silence. A target that
has never reported one still lands on UTC, which is the previous behaviour made
explicit rather than assumed.

The dialog now states which clock the hours are on, and says so differently when
that clock is not the operator's own. Stating it is the other half of the fix:
the server can pick the right zone, but the user still has to be able to see it.

Tests pin both directions and, most importantly, that creation and playback
resolve identically from the same device row.

ScreenTinker 866e35a2b2 Clear a device's OTA rate state when it proves its identity
The update check is deliberately unauthenticated — every client version has to be
able to ask, including old ones that never learned to send a token — and it keys the
rate breaker on the caller-supplied device_id. Keying on IP is not available either:
the fleet SNATs behind one address, so per-IP would collapse a whole site into a
single bucket.

The result was that the bucket belonged to whoever cited the id rather than to the
device that owns it. A handful of requests naming a panel's UUID left that panel in
rate-backoff, un-updatable for up to half an hour at a time and renewable
indefinitely, while every other device stayed healthy.

Rather than adding auth (which would strand old clients) the state is now
self-healing: when a device registers on the /device socket with a valid device_token
its bucket is cleared. Noise is still possible, but it now lasts until the panel's
next genuine reconnect instead of as long as someone keeps poking.

This is not an escape hatch from the breaker's real job. A device stuck in an update
loop is re-registering legitimately, and clearing its rate state on each genuine
reconnect is what a healthy device looks like; the loop protection that matters is
the download guard. The version-keyed bucket that covers old clients sending only
?version= is a separate namespace and is deliberately not reachable this way.

ScreenTinker cbc00515e2 Scope device serialization to what each endpoint actually needs
A device row carries two fields that are not ordinary data: device_token, the
credential the player proves with on the /device socket, and settings_pin, which
unlocks the player's on-device settings menu and so hands physical control of the
panel to anyone holding it.

device_token was already stripped everywhere. settings_pin was not — it went out on
both the collection and the detail endpoint. The dashboard does show it, but on one
screen only: the device detail page, which fetches a single device. The collection
endpoint had no consumer for it and was returning the PIN for every device in the
workspace on every load.

The detail endpoint keeps it, so that page is unchanged. The list no longer sends it.
Same data, much smaller blast radius, no feature lost.

Tests pin the split in both directions — absent from the list, present on the detail,
and the socket credential absent from both (asserted on the whole serialized payload,
not just the top-level key, so a nested echo would fail too).

ScreenTinker d4cf1d4123 Merge branch 'feat/self-service-password-reset' 2026-07-27 11:21:36 -05:00
ScreenTinker b7d55595af feat(auth): self-service password reset
Until now the only ways back into an account were an admin setting your password for you
or shell access to run scripts/reset-admin.js. A self-hosted operator who forgot their
password had no path at all, and the admin-reset route explicitly refuses to reset a
platform admin's password — so a single-admin instance was unrecoverable without a shell.
The per-account login lockout added recently makes that sharper: a user who forgets their
password will hit the lockout and see the same generic error, with no way out.

Two unauthenticated endpoints (they must be — the user cannot log in):

  POST /api/auth/forgot-password   { email }             -> always the same 200
  POST /api/auth/reset-password    { token, password }   -> 200 / 400

The properties that matter, each covered by a test:

- NO ENUMERATION. The request endpoint answers identically — same status, same body —
  for a real address, an unknown one, an SSO identity with no local password, and a
  malformed string. The frontend shows the same confirmation even on a network error,
  so the client cannot leak what the server refused to.
- NO MFA BYPASS. Completing a reset does NOT issue a session; the user signs in
  afterwards, so a TOTP-enabled account still clears its second factor. Returning a token
  here would turn "read one email" into a full session without the second factor.
- SINGLE USE, SHORT LIVED. 32 random bytes, stored only as a SHA-256 hash (same
  discipline as email verification, recovery codes and API tokens), 1h TTL, and the
  redeeming UPDATE is conditioned on the hash still being present so concurrent
  redemptions cannot both win.
- LOCAL ACCOUNTS ONLY. SSO identities have no local password; no token is minted.
- IT ACTUALLY UNBLOCKS YOU. A completed reset clears the per-account login lockout and
  must_change_password, otherwise someone who locked themselves out would reset and still
  be locked out.

Rate limited: 5/min on the request (it sends mail to a caller-supplied address), 10/min
on the redeem. If no email transport is configured the response is unchanged — no oracle —
but the server logs loudly, because the user will otherwise wait for mail that cannot
arrive and the generic response cannot tell them.

Frontend: a "Forgot your password?" link on the sign-in card, a request card, and a
new-password card. app.js had to learn #/reset-password explicitly — the auth guard
rewrites any unauthenticated hash to #/login, which would have discarded the one-time
token in the emailed link and made it silently do nothing.

Migration adds users.password_reset_hash / password_reset_expires: additive, nullable,
idempotent; a code-only rollback leaves two dead columns.

ScreenTinker 090b6c12cb fix(pairing): expire a pairing code on device liveness, not row age
A screen that was still connected and still displaying its pairing code could not be
paired. Reloading the player produced the same code, and the on-screen instruction
("restart the display to get a new code") could not help.

devices.created_at is written once, at first registration, and the row is never recreated:
a player persists its device_id and its pairing code in local storage and re-registers
with them forever. Expiry was measured from created_at, so 15 minutes after first boot the
row became permanently unclaimable while the device kept heartbeating — and a restart
reused the stored identity and reproduced the same code, so there was no way out.

Observed in production: an unclaimed web player, still online and heartbeating, whose row
was created 4 days 20 hours earlier and had been unpairable for all but its first 15
minutes. Prod is carrying several such rows; alpha has some 13 days old.

Key expiry on last_heartbeat instead, falling back to created_at for a row that has never
checked in. That answers the question the operator actually has — is this screen still
there showing me this code? — while keeping the property the expiry exists for: a device
that has genuinely gone away still expires.

Trade-off, taken deliberately: a code stays claimable while its screen is connected rather
than for a fixed 15 minutes. That is what the product implies, since the code is on the
screen the whole time, and guessing is bounded by lib/pair-lockout (5 failures per IP per
15 min) and the 5/min route limit rather than by this TTL.

SERVER-ONLY. The player's device:registered handler reads only device_id and device_token
and has no way to display a server-issued code, so reissuing one would have left fielded
players showing a stale code — strictly worse. This fix needs no player update and
un-strands every already-affected device in the field on deploy.

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

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

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

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

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

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

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

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

ScreenTinker dce0bc6f54 fix(devices): generate access-gating six-digit codes with a CSPRNG
The on-device settings PIN (devices.settings_pin, minted at pairing) and the pairing code
assigned to imported devices both came from
`Math.floor(100000 + Math.random() * 900000)`.

Math.random is not a CSPRNG. V8 implements it as xorshift128+, whose internal state is
recoverable from a handful of consecutive outputs, and every call in a process draws from
that one shared stream. Both values are also observable by ordinary users — settings_pin
is returned in device API responses today — so a user who collects a few outputs could
predict the values minted around them, including for other tenants.

lib/numeric-code.sixDigitCode() uses crypto.randomInt, which is CSPRNG-backed and
rejection-samples so the distribution stays uniform. Range is 100000..999999 inclusive,
identical to the old expression, so codes are still exactly six digits with no leading
zero — the on-device keypad and pairing UI are unchanged.

Deliberately NOT converted, because neither gates access: the image-generation seed in
lib/image-gen.js, and the anti-burn-in pixel jitter inside generated widget HTML.
Also unchanged: the settings_pin backfill in db/database.js, which uses SQLite's random()
— that is ChaCha20 seeded from OS entropy, not a weak PRNG.

This is the generator half of the finding only. The separate half — that settings_pin is
returned to every workspace member, including read-only roles — is a response-shape change
and waits on the consumer enumeration.

ScreenTinker 9130aa5f7d feat(auth): bound password login per account, not only per IP
The only throttle on POST /api/auth/login was the per-IP limiter in server.js. That
bounds one noisy source and nothing else: it does not bound a distributed attempt, and
it is only as accurate as a deployment's proxy configuration. Nothing counted failures
against the account actually being attacked, and nothing cleared such a count on success
because no such count existed.

lib/login-lockout.js mirrors lib/totp-lockout.js and lib/pair-lockout.js so there is one
lockout idiom here rather than three. 10 failed passwords lock an account for 15 minutes.

Keyed on user.id, never on the submitted email: the email is attacker-supplied and
unbounded, so keying on it would let anyone grow the Map without limit — the same class
of bug fixed elsewhere in this campaign. A user id only exists for a real account, so the
key space is bounded by the user table and needs no eviction sweep, exactly like
totp-lockout.

A locked account returns the SAME 401 and body as a wrong password. A distinct 429 would
tell an attacker "this account exists and is under attack", turning login into an
account-existence oracle; the test asserts the locked response is byte-identical to both
the wrong-password and unknown-account responses. The trade is that a locked-out
legitimate user sees the generic message, so the trip is recorded in activity_log
(auth:login_locked) for the operator instead.

The counter is cleared as soon as the password verifies — before the TOTP and
email-verification branches, which return early and never reach issueSession, so a reset
placed there would never fire for those accounts. SSO paths do not share this code and
are unaffected.

Frontend needs no change: login.js renders any non-ok body's `error` string verbatim, and
the body is unchanged.

ScreenTinker 8a28761b12 fix(widgets): bound the unauthenticated telemetry store, and stop it writing rows
The diag widget runs in a null-origin sandboxed iframe, so it cannot carry a session and
its telemetry POST must stay unauthenticated. But the handler stored into a plain Map
keyed on a value taken from the request body, with no cap, no TTL and no eviction — an
unauthenticated caller could add entries until the process died. On this product a dead
server is a fleet-wide reconnect, so a bound here is a fleet-safety control.

Two changes:

- lib/bounded-snapshot-store.js: a "latest snapshot per key" store with a global entry cap
  and a TTL, evicting least-recently-WRITTEN. The cap is GLOBAL rather than per-IP on
  purpose — signage sites egress through one NAT address, so a per-IP limit punishes a
  whole venue for one noisy panel and does nothing about a distributed writer. Same
  reasoning the OTA download guard already documents ("NEVER per-IP (SNAT)"). A live panel
  rewrites its key every 2.5s, so only entries the dashboard already treats as stale
  (>15s) are ever eligible for eviction.

- The POST now answers 204 instead of res.json({ok:true}). The reporting widget ignores
  the response (fetch(...).catch()), and services/activity.js activityLogger wraps
  res.json — so this also stops an anonymous caller from writing one activity_log row, and
  running two synchronous statements, per report.

Read contract unchanged: a live key returns its object, an unknown OR expired key returns
null — the shape frontend/js/views/device-detail.js already handles ("no report yet"), and
it treats anything older than 15s as stale regardless, so the 60s TTL is 4x looser than
what the UI honours. No client change; no rate limiter added.

ScreenTinker 6b082cfad0 fix(uploads): derive stored type from file content, and never serve uploads as documents
Uploaded files are served from the SAME ORIGIN as the dashboard, so how a browser
interprets them is a security boundary. Two things decided that interpretation, and
both were caller-controlled: the stored extension came from
`path.extname(originalname)`, and the only type check read `file.mimetype` — a request
header. A caller could therefore choose to have their bytes served as an active
document from the app origin.

Two independent invariants now hold the boundary:

1. INGEST — lib/upload-sniff.js sniffs magic bytes after multer writes a neutral
   `.part` file (diskStorage names the file before any bytes exist, so the sniff cannot
   happen there), maps the result through a hardcoded mime->extension allowlist, renames
   accordingly, and stores the sniffed mime. Unsupported bytes are refused with a 400.

2. SERVING — upload responses carry `Content-Security-Policy: sandbox`, so if a response
   is ever treated as a document it lands in an opaque origin with scripts disabled.
   Anything outside the inline-safe extension set is additionally forced to download.
   This holds regardless of how a file reached disk, so a future gap in (1) is contained
   rather than exploitable.

Applied at every instance of the pattern, not just the first: lib/content-ingest.js,
the /replace route, the four content-serving paths across server.js and routes/content.js
(the latter pair currently shadowed by mount order, which is not a guarantee), and the
ZIP-import path in routes/status.js, which took its extension from the archive entry.

SVG stays accepted and stays inline: white-label logos are SVG, and octet-stream +
nosniff makes <img> fail. Scripts in an SVG never run in an image context, and the
sandbox CSP covers the one case where they would — a direct navigation. SVG is also no
longer handed to sharp, which removes the librsvg path where the open libvips CVEs live.

Existing rows are untouched — no migration. The four upload fixtures in agency.test.js
uploaded `Buffer.from('x')` declared as image/png; that is the exact "declared type is a
lie" case this closes, so the fixtures now use real PNG bytes. No assertion changed.

ScreenTinker 6dd78e078a refactor(auth): drop the unused optionalAuth middleware
optionalAuth was exported but never mounted on any route (verified by grep across
server, frontend, scripts and tests: only its own definition, its export, and one
stale comment referenced it). It also carried a second, slightly different copy of
the token-resolution logic - its own user column list, and no forced-password-change
check - which is exactly the drift the preceding commit consolidates away.

Removing it rather than porting it to resolveSessionUser: a "set req.user if a token
happens to be present" middleware is a few lines on top of the shared resolver if a
route ever needs one, and an unused export is a standing invitation to mount it.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

'upgrade' device_events row (detail 'old → new'). Server-side, so it covers Android/Tizen/web with
no client change; a fresh pair (no prior version) isn't counted. Adds device.event.upgrade label.

(coded 1920x1080 + 90° Display-Matrix) or a portrait photo (EXIF orientation 6) was
stored LANDSCAPE. The player then rendered it wrong-aspect and letterboxed — the
"portrait content degraded + blue bar at the bottom" symptom in #170. The reporter's
workaround (pre-rotate + mark Landscape) is exactly what this bug forces.

- lib/media-orientation.js (new): pure, unit-tested display-dimension helpers = single
  source of truth for ingest AND the backfill. videoDisplayDims() reads the modern
  Display-Matrix side_data rotation (falls back to the legacy tags.rotate, sign-normalized);
  imageDisplayDims() honors EXIF orientation 5..8. Odd quarter-turns swap W/H.
- lib/content-ingest.js: use the helpers for stored dims; add sharp .rotate() so image
  THUMBNAILS are auto-oriented too (video thumbs were already auto-rotated by ffmpeg).
- scripts/backfill-rotation-dims.js (new): idempotent, dry-run-by-default maintenance to
  correct already-uploaded portrait media (re-probe -> fix dims -> regenerate image thumbs).
- test/media-orientation.test.js: 5 bites (tag + Display-Matrix, sign/normalize, EXIF 5..8,
  the blue-bar landscape->portrait case, null-safety).

Scopes #170 to its residual-on-1.9.4 issues; the 1.9.3 "never displays" slice was #162 +
the remote_url-null download fix, already shipped in 1.9.4. The slow low-res/orientation-
cycling first load is tracked separately in #170 pending repro data.

* fix(android): honor EXIF orientation in ImageLoader so portrait photos render upright (#170)

Completes the rotation-aware media fix on the PLAYER side. The server ingest fix (this
branch) corrects stored dimensions + auto-orients the thumbnail, but the panel draws the
full-res original via BitmapFactory, which ignores EXIF — so a portrait photo (landscape
pixels tagged "rotate 90") still rendered sideways on the screen. QA root-cause pass on
#170 caught this gap: the Android player reads no stored dims and applied no EXIF.

ImageLoader now reads the EXIF orientation (from the file for cached content, from the byte
stream for remote_url images — ExifInterface(stream) is API 24+, minSdk is 24) and rotates/
flips the decoded bitmap via a Matrix (all 8 orientations). NORMAL/UNDEFINED is a no-op (no
extra allocation); a transformed copy recycles the source; OOM falls back to the source
rather than crashing. Videos were already correct (ExoPlayer honors the rotation matrix).

Verified: :app:compileDebugKotlin clean.

Refs #170. Rides with the server rotation-dims fix on this branch.

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

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

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

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

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

Closes #158.

Some checks failed
CI / Unit tests (node --test) (push) Has been cancelled
CI / OpenAPI spec lint (push) Has been cancelled
CI / Android unit tests (Kotlin schedule evaluator vectors) (push) Has been cancelled
CI / Boot smoke + version check (push) Has been cancelled
* 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.

ScreenTinker 147ab6d3c8 fix(ota): treat legacy -patchN as a released version so the old fleet is offered updates
The -patchN scheme (e.g. 1.9.2-patch3) parses as a semver prerelease, so decide()'s
superseded-prerelease guard refused to offer a newer stable core (1.9.3) to the existing fleet —
stranding every 1.9.2-patchN device on OTA (Force Update didn't help; the re-check re-returned
superseded-prerelease). isReleased() now counts -patchN as a shipped release, so those devices get
offered 1.9.3 via normal OTA, while GENUINE prereleases (-beta/-rc/-alpha) keep prerelease semantics
and newer cores are never downgraded. 6 new tests + 14 existing OTA tests green (388/388 suite).

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

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

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

ScreenTinker 2ba06e98ec feat(#150): preserve per-device settings across delete+re-pair (fingerprint-keyed)
Delete+re-pair mints a new device row whose INSERT omits every setting, silently resetting
orientation/name/playlist/etc to defaults (Bold MDM churn). Add a fingerprint-keyed
device_settings table (no FK to devices -> survives the cascade): snapshot on DELETE, auto-
restore on fingerprint-match re-pair (relinking the fp to the new id), operator re-adopt API
(GET /devices/removed + POST /devices/:id/re-adopt) for the changed-fingerprint case. Purge on
workspace/user/org deletion (no cross-tenant bleed). Orientation enum-validated on PUT + restore.
blocked preserved (re-enforced by the register kill-switch). Wall membership deferred (TODO).

Backend only — frontend re-adopt UI NOT built (awaiting API review). Local only, no bump/tag.

ScreenTinker e1ce36b2a8 fix(#148) patch2: per-device session-settle debounce — absorb duplicate-socket storms
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.

ScreenTinker bcfe3eaf8b fix(#148) Items 2-4: mark-offline closes the socket + tighten ping + TCP keepalive
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.

ScreenTinker 8809007d9e fix(#148) Item 1: exempt paired+authenticated devices from the flap-limiter quarantine
The flap-limiter could 30-min quarantine a PAIRED, legitimate device on reconnect churn.
Behind Bold's single SNAT IP a repeated edge flush -> every device reconnects -> trips flap
-> quarantined -> a recoverable blip becomes a SUSTAINED FLEET-WIDE LOCKOUT we caused.

check(key, now, {paired}) now skips (and clears) the quarantine escalation for a paired
device — it still gets the brief soft cooldown if it truly hammers, but never the long
lockout. The register gate computes paired = device_id && validateDeviceToken(...) (a
matching STORED token, false for missing/mismatch) so a spoofed device_id can't claim the
exemption; unpaired/anon flapping (attacker / unprovisioned hammering) still quarantines.

Tests: unpaired flapper still quarantined; paired never quarantined (soft cooldown only);
paired creds RELEASE an in-flight quarantine; N paired devices from one SNAT IP all admitted
on reconnect and never quarantined across repeated flush cycles.

ScreenTinker b57e7eec7f fix(#146): web player — reconnect drops video to "Waiting for content" (idle reset over live playback)
CONFIRMED from a live console capture (restore cache -> video plays -> reconnect ->
"Playlist unchanged" -> screen falls to "Waiting for content..."). Audio survived because
only the "showing content" VIEW was covered, not the audio path.

ROOT CAUSE: the server re-emits device:paired on EVERY re-register of an already-paired
device (ws/deviceSocket.js:510) — i.e. on every reconnect, while content is already playing.
The player's device:paired handler called showStatus('Waiting for content...') UNCONDITIONALLY
(the "falls through to idle" sibling), putting the idle overlay OVER the live video. The
following device:playlist-update -> "Playlist unchanged" branch returned early and never
cleared it, so the idle screen stuck on top of playing content.

FIX (idle screen only when genuinely idle; unchanged is a strict no-op that keeps playback):
- lib/player-media-health.js: new shouldShowIdle(state) — idle ONLY when nothing is playing
  AND there's genuinely no content. Already-playing (or content-present-about-to-render) is
  never idle.
- device:paired handler: gate showStatus on shouldShowIdle({isPlaying, hasContent}) instead
  of showing it unconditionally. On a reconnect while playing -> no-op.
- "Playlist unchanged" branch: when healthy playback is confirmed, hideStatus() to clear any
  stale idle overlay a reconnect's device:paired may have put up — so the confirmation can
  never leave "Waiting for content..." over live content. Still leaves the actual media
  element exactly as-is (no teardown, no flicker).
- sw.js cache v10 -> v11.

SIBLING SCAN: device:paired was the only unconditional idle reset. The connect() idle
prompts (connecting / connecting_muted) were already guarded by !isPlaying; empty-playlist
and no-renderable idles are genuine.

Tests: player-media-health.test.js +2 (shouldShowIdle: playing never idle; idle only when
empty+not-playing). Inline player JS syntax-checked; module served + guard referenced on a
booted server. Suite 318/318.

ScreenTinker 26c72d62bf fix(#146): web player — no-change refresh loses video (keeps audio); re-attach idempotently
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.

ScreenTinker 385eda3cb1 feat(#146): owner-only CLI to mint billing:read tokens (scripts/mint-billing-token.js)
The billing:read scope + dual-path gate were built but there was no way to MINT a token
(and it must NOT go in the workspace-scoped, self-service API-Tokens UI). Adds a server-side,
owner-only CLI — no new UI, no network endpoint. Owner-only BY CONSTRUCTION: it's a
host-side script, so filesystem/shell access = the platform owner.

- server/lib/billing-token.js (testable): mintBillingToken/revokeBillingToken/
  listBillingTokens. Reuses the EXACT existing token path — same secret (st_ + 32 bytes
  base64url), same SHA-256 hashing (hashToken), same api_tokens columns — no second format.
  Resolves the platform OWNER (oldest platform_admin/superadmin; #14 collapsed superadmin ->
  platform_admin so that's the top tier) and binds to their workspace. api_tokens.user_id +
  workspace_id are BOTH NOT NULL (no platform-level token exists); the workspace binding is
  VESTIGIAL for billing (billing:read is off-ladder -> can't reach any workspace router;
  billing is platform-global), documented in-file rather than loosening NOT NULL pre-release.
- scripts/mint-billing-token.js: thin CLI wrapper. --name mints and prints the secret ONCE
  (+ id, + "run as owner on host" warning), --list, --revoke <id> (soft revoke, mirrors the
  dashboard DELETE).

Tests (4, test/billing-token-mint.test.js): minted row is scope EXACTLY billing:read with a
matching SHA-256 hash and no read/write/full/agency scope; the token reads GET
/api/billing/usage (200) but is refused on /api/devices (403) and /api/admin (401) — scope
isolation; revocation -> 401; mint requires a name; revoke refuses a non-billing id. CLI
smoked live (mint/list/revoke). Suite 310/310.

SPEC-vs-REALITY (again): spec said bcrypt + JSON `scopes`; this codebase uses SHA-256 + a
single `scope` TEXT column. Built to the real system.

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

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

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

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

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

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

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

3. Admin toggle: GET/PUT /api/admin/status-debug (requirePlatformAdmin, mirrors the

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 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

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

- OTA_DOWNLOAD_GUARD_ENABLED=false -> download guard always admits.
- MAINTENANCE_BAND_GATE_ENABLED=false -> interval maintenance ignores band.
- CONNECT_RATE_QUARANTINE_TRIPS=0 -> quarantine off (already; confirmed).

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 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 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 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 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 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 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 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 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 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.

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 f06a87f4be fix(api): harden device pairing against brute-force (#87)
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.

Closes #87

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

ScreenTinker 0d14db97a6 feat(admin): Delete Organization + Workspace with cascade (#36)
Platform admins can now cleanly remove a customer org (account ends) or a stray
workspace from the UI, instead of raw SQL that risks orphaning resources.

The tenant cascade isn't pure DB CASCADE - workspace-scoped tables (devices,
content, playlists, ...) are NO ACTION and must be purged before the workspace.
Extracted that logic out of deleteUserCascade into shared deleteWorkspaceCascade /
deleteOrgCascade helpers (one tested implementation; deleteUserCascade now reuses
the purgeWorkspaces extraction).

Backend (platform-admin only): GET /api/admin/orgs (list + owner + counts +
workspaces), DELETE /api/admin/orgs/:id, DELETE /api/admin/workspaces/:id.
UI: an Organizations section in Admin listing every org/workspace with a
type-the-name confirmation before the irreversible delete.
Tests: org/workspace cascade (real FKs) + endpoint gating/404. Suite 53/53.

ScreenTinker ba3e2cc785 fix(security): patch quick-win findings from the codebase review
Five low-risk, high-value fixes surfaced by the security review:

#3 Branding lockdown — `custom_domain`/`custom_css` (which feed the PUBLIC,
   pre-auth branding resolver and the login-page <style>) are now settable only
   by platform admins; a workspace_admin can no longer hijack the platform login
   page by claiming its domain. The public /api/branding (+ /domain) now return
   only presentational fields via publicBranding() (no id/user_id/workspace_id/
   custom_domain/timestamps leak).

#6 Strip device_token — the device WS auth secret (validated with
   timingSafeEqual) was returned in device list/get/update + pairing responses
   (SELECT d.* / *). New lib/device-sanitize.js strips it everywhere; prevents
   device impersonation by any workspace user.

#7 must_change_password enforced server-side — was a frontend-only redirect, so
   a provisioned temp password worked indefinitely via the API. requireAuth now
   403s every route except GET/PUT /api/auth/me (the password change, which
   clears the flag) and logout while the flag is set.

#8 XSS — escape user data interpolated into innerHTML in teams.js, kiosk.js,
   layout-editor.js (team/page/layout/zone names, member name/email, kiosk
   config fields). scriptSrcAttr 'unsafe-inline' made these exploitable via
   injected event handlers, not just markup.

#9 Thumbnail IDOR — /api/content/:id/thumbnail had no auth/scope gate (any UUID
   served any tenant's thumbnail). Now mirrors the /file route's playlist/widget
   workspace-scoped reference check.

Tests: new test/security-fixes.test.js (device strip, publicBranding field
allowlist, must_change_password gate). Full suite 41/41. Verified live against a
prod-data copy: device_token absent from /api/devices, /api/branding trimmed.

Not addressed here (tracked for follow-up): Android OTA signature verification
(Critical), public widget-render XSS, token revocation/logout, pairing-code
strength, validateRemoteUrl hardening, import quota.

ScreenTinker eb13f716d0 feat(branding): instance-level default white-label branding (#15)
White-label is stored per-workspace (white_labels.workspace_id); unbranded and
new workspaces - and the login page - fell back to hardcoded ScreenTinker. Add a
single platform default that everything inherits beneath the per-workspace layer.

Resolution (lib/branding.js): workspace row -> custom-domain match -> platform
default -> hardcoded ScreenTinker. Row-level override: a workspace with its own
row keeps it (current behavior); only row-less workspaces inherit the default,
so editing the default propagates instantly (no row-copying at creation).

The platform default is a white_labels row with a FIXED id ('platform-default'),
not a "workspace_id IS NULL" sentinel - legacy pre-multitenancy rows can also
have a null workspace_id, which would be ambiguous.

- routes/admin.js: GET/PUT /api/admin/branding (requirePlatformAdmin) to read/
  upsert the single platform-default row; audit-logged.
- server.js: public GET /api/branding (domain match -> platform default ->
  hardcoded) for pre-login/pre-workspace contexts.
- routes/white-label.js: authed GET now falls back to the platform default
  (was hardcoded) for row-less workspaces.
- Frontend: login page resolves + applies branding (logo, name, colors, favicon,
  custom CSS) pre-auth; Admin page gets a "Default branding" form.

Tests: resolver order incl. legacy null-ws safety; admin GET/PUT (single row,
upsert, platform-admin-only 403). Full suite 37/37. Verified end-to-end:
public + authed + login-page all inherit the platform default; per-workspace
override preserved.

2026-06-08 16:55:22 -05:00
ScreenTinker 66c95bb331 fix(db): cascade tenant resources on workspace/org delete (#18 follow-up)
The #18 user-delete bug was the first symptom of a broader gap: 13 tables
reference workspaces(id) (and activity_log also organizations(id)) with NO
ACTION, so deleting a workspace or organization fails the same FK wall once it
holds any content. SQLite can't ALTER an FK action, so this migration rebuilds
each table (the create-copy-rename pattern the assignments/schedules migrations
already use), changing only the tenant FK clause:
  workspace_id -> ON DELETE CASCADE   (resources belong to the workspace)
  activity_log.workspace_id / organization_id -> ON DELETE SET NULL (keep audit)

user_id FKs are intentionally left as-is - user deletion stays handled app-side
by lib/user-deletion.js (the #18 fix).

- lib/tenant-cascade-migration.js: pure, idempotent core (table-existence
  guarded; transforms the stored CREATE text, copies rows verbatim, recreates
  indexes; fixes activity_log's AUTOINCREMENT sequence; baseline-vs-after
  foreign_key_check so pre-existing orphan rows don't abort it but a botched
  rebuild does).
- db/database.js: boot wrapper owns the pre-migration snapshot + process.exit
  on failure, matching the other heavy migrations.

Tests (node:test): reproduces the workspace-delete FK failure, applies the
migration, verifies FK actions (CASCADE / SET NULL), index recreation, data
preserved, and that workspace/org delete now cascades (activity_log preserved).
Full suite 27/27. Verified on a copy of a real DB: 13 tables rebuilt,
integrity_check ok, workspace delete cascades, no new FK violations.

ScreenTinker 05f9c20ecf fix(admin): user deletion failed with FOREIGN KEY constraint (#18)
DELETE /api/auth/users/:id ran a bare `DELETE FROM users`, but 23 columns
reference users(id) and only 4 cascade, so with foreign_keys=ON the delete
fails the moment the user is referenced anywhere - and a real user always is
(owns an org, created a workspace, has login activity). Reproduces on a fresh
DB, exactly as reported.

The schema also lacks cascades from workspaces -> tenant resources, so the DB
can't clean up on its own. New lib/user-deletion.js resolves every reference in
one transaction (defer_foreign_keys=ON for forgiving order; table-existence
guard for resilience):
  - Refuse (409) if the user OWNS an organization that has other members -
    don't nuke a shared tenant; transfer ownership first.
  - Hard-delete the organizations they SOLELY own (workspaces + all contents).
  - In orgs they don't own, PRESERVE resources: SET NULL the nullable
    creator/inviter columns, and reassign the NOT NULL legacy creator user_id to
    the resource's org owner (fallback: the acting admin).
  - Memberships (organization_members/workspace_members/team_members/
    content_folders) cascade on the user delete; pending invites they sent and
    legacy teams they own are removed.

The handler now 404s an unknown id and 409s the shared-org case.

Tests (node:test): reproduces the FK failure, then verifies provisioned-member
delete (resources preserved + unlinked/reassigned), solo-org-owner cascade,
shared-org refusal (409), self-delete 400, non-superadmin 403, unknown 404.
Full suite 22/22. Verified end-to-end on a copy of a real DB: deleted a user
owning 2 solo orgs, foreign_key_check clean.

Closes #18.

ScreenTinker 48902f6807 feat(roles): add cross-org platform_operator staff role (#13)
platform_operator is cross-org STAFF: it can see and act-as into every
org and read/write workspace-scoped resources (content, playlists,
layouts, schedules, devices, widgets, kiosk) anywhere - but holds NO
owner-level power.

Design is deny-by-default: operator is NEVER added to PLATFORM_ROLES /
isPlatformRole, so every owner capability (billing, org/workspace
deletion, user/role management, shared & template asset curation,
branding, workspace member mgmt/rename) stays denied, and any NEW owner
endpoint added later inherits that denial automatically.

Operator gets power from exactly two levers:
- middleware/auth.js: new PLATFORM_STAFF set + isPlatformStaff(); owner
  guards (PLATFORM_ROLES, requireAdmin, requireSuperAdmin) unchanged.
- tenancy.js: accessContext + resolveTenancy treat staff as act-as
  capable; new req.isPlatformStaff / req.isPlatformOperator (req.isPlatformAdmin
  stays owner-only); accessibleWorkspaceIds + switch-workspace guard use staff.
- permissions.js: canRead/canWrite + canAccessWorkspace (read) grant staff;
  canAdmin / canAdminWorkspace / isOrgAdmin / isOrgOwner stay owner-gated.

Read-only edges (per review): operator may VIEW workspace member lists
(canAccessWorkspace) and the unassigned device pool (devices.js), but
cannot mutate either.

Frontend: platform role dropdown adds "Platform operator"; the user-mgmt
view stays isPlatformAdmin-gated so operators can't open it. EN i18n only.

Behaviour identical under HOSTED_INSTANCE set or unset.

ScreenTinker 797eab7c8d refactor(roles): normalize the platform-role model (#14)
The legacy /api/auth/users dropdown could write 'superadmin' and 'admin'
role strings that not every code path recognized. Some checks matched only
'platform_admin' (tenancy accessContext/resolveTenancy), so a 'superadmin'
user could list orgs but not act-as into them.

Normalize to the current two-tier platform model (users.role holds the
PLATFORM role only; org/workspace roles live in the membership tables):

- Migration (idempotent, exact-string): superadmin -> platform_admin,
  admin -> user. No-ops on rows already in the current model.
- Add isPlatformRole() helper in middleware/auth.js; route the two
  superadmin-excluding checks in tenancy.js through it so a stray
  'superadmin' is never treated as lower-privileged (fixes act-as).
- Remove the dead/stricter requirePlatformAdmin in permissions.js (bare
  === 'platform_admin'); the single guard is the one in middleware/auth.js.
- Recovery-token default role admin -> platform_admin so emergency
  recovery keeps full access once 'admin' no longer implies elevation.
- PUT /api/auth/users/:id/role whitelist -> ['user','platform_admin'];
  self-demote guard retargeted via isPlatformRole.
- Frontend: platform user-management dropdown now offers User / Platform
  admin only; owner-delete guard and settings highlight use isPlatformAdmin.
  EN i18n: add admin.role.platform_admin.

Behaviour is identical under HOSTED_INSTANCE set or unset; the migration
only touches exact legacy strings.

- DELETE /api/workspaces/:id/members/:userId   (workspace_admin)

                                                case-insensitive
                                                email match)

Permission gating:
- canAdminWorkspace (existing) for admin-gated endpoints
- canAccessWorkspace (new helper in lib/permissions.js) for the
  members read endpoint - mirrors canAdminWorkspace shape but
  admits any workspace_members role plus org/platform paths

Security additions vs the original plan:
- Transaction-bounded collision check on POST /invites closes the
  TOCTOU race between simultaneous duplicate POSTs (no UNIQUE
  constraint on workspace_invites(workspace_id, email))
- Per-(inviter, workspace), hour-window rate limit on POST /invites
  to prevent abuse / cost runaway. Env-configurable via
  INVITE_RATE_LIMIT_PER_HOUR with conservative 50/hour default.
  429 response is generic - does not echo the configured value.
- Invite expiry env-configurable via INVITE_EXPIRY_DAYS (default 7)
- PUBLIC_URL env var (optional) pins the accept-URL origin in prod;
  falls back to request-derived for local dev

Rollback rule on email send: only graph_error (real send attempt
failed at Graph) deletes the row and returns 502. not_configured
and dev_restricted are intentional non-sends - keep the row, count
against rate limit, allow local accept-invite testing to proceed.

Other safety blocks:
- Cannot demote/remove the last workspace_admin (409)
- Cannot remove the parent-org's org_owner via workspace path (403)
- Accept-invite is idempotent if user already a member
- Expired invites delete-on-read and return 410
- Wrong-account accept returns 403 without touching the invite

Expired-invite cleanup added to services/heartbeat.js mirroring
the team_invites sweep pattern.

Verification: 9-case curl-driven E2E against the dev DB fixture
(switcher-test + invitee-existing + invitee-new mid-flow register).
All 9 pass: create / collision-409 / second-create / rate-limit-429 /
existing-user-accept / register-then-accept / wrong-account-403 /
expired-410 / viewer-cannot-invite-403.

ScreenTinker d2a3bdfd15 fix(auth/me): broaden non-admin accessible_workspaces to include org_owner/org_admin paths
The non-admin branch of /me's accessible_workspaces query drove
from workspace_members, so users with org_owner or org_admin on
an organization but no direct workspace_members row were missing
those workspaces from their /me response - and therefore from the
switcher dropdown. Mirrors the access logic in
accessibleWorkspaceIds() (lib/tenancy.js) while keeping the
full-row SELECT shape /me needs.

Verified end-to-end with switcher-test@local.test acting as
org_owner of Acme Studios with no workspace_members row on
Studio B - Studio B now appears in /me's accessible_workspaces
with workspace_role: null, can_admin: true.

Also updates the stale TODO comment in tenancy.js that flagged
this exact gap.

ScreenTinker 742d8c4b09 feat(socket): delivery queue for offline-device emits
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.

ScreenTinker fc29843035 feat(socket): Phase 2.3 workspace-scoped dashboard socket rooms + per-command permission gates. Dashboard namespace was previously a flat broadcast - every connected dashboard received every device's status/screenshot/playback events platform-wide (foreign device names + IPs included). Inbound socket commands gated by a legacy admin/superadmin role check that was dead code post-Phase-1 rename.
Fix: at connect, enumerate the user's accessible workspace_ids (direct workspace_members + org_owner/admin paths + platform_admin 'all') via new accessibleWorkspaceIds() helper in lib/tenancy.js; socket.join one room per workspace. All 12 dashboardNs.emit sites across deviceSocket / heartbeat / server.js / devices route / video-walls route now route via dashboardNs.to(workspaceRoom(...)).emit() with the workspace looked up from the relevant device or wall. New lib/socket-rooms.js holds the helpers and breaks a circular dependency (dashboardSocket already requires heartbeat, so heartbeat can't require dashboardSocket).

Inbound 6 commands rewired to canActOnDevice(socket, deviceId, tier): request-screenshot is read tier (workspace_viewer+); remote-touch/key/start/stop and device-command are write tier (workspace_editor+). Platform_admin and org_owner/admin always pass via actingAs. Legacy admin/superadmin branch dropped.

Lifecycle note: workspace-switch already calls window.location.reload (Phase 3 switcher), which forces a fresh socket with updated memberships - no per-emit re-evaluation needed.

Smoke tested with 3 simultaneous socket.io-client connections (switcher-test, swninja, dw5304 platform_admin) + direct canActOnDevice invocation for 6 user/device/tier combinations. All 9 outbound isolation cells and all 6 permission gates pass. Fixture mutation: switcher-test's Field Crew membership flipped from workspace_editor to workspace_viewer to exercise the read/write tier split in one login.

ScreenTinker 56da64d0cd feat(workspaces): rename via switcher dropdown - new PATCH /api/workspaces/:id route, per-row pencil affordance in switcher (visible only when caller can_admin), small rename modal with name + slug fields, validation (name <=80 chars, slug ^[a-z0-9]+(?:-[a-z0-9]+)*$ <=60 chars, blank slug -> NULL), 409 on per-org slug collision. Permission gating via new canAdminWorkspace(db, user, ws) helper in lib/permissions.js - reused-ready for future Phase 3 admin actions. /me query now joins organization_members to compute can_admin per accessible_workspaces entry. Drive-by fixes surfaced: (1) activityLogger method filter was missing PATCH, added; (2) routes that operate on a target workspace by URL param need to stamp req.workspaceId from the param so activityLogger captures the right tenant attribution - documented in the route. Smoke fixture: switcher-test@local.test is workspace_admin of Studio A and workspace_editor of Field Crew (no org_owner) so the can_admin true/false split is exercised in one login. 2026-05-12 11:06:55 -05:00
