ScreenTinker b34d73dbb9 Report zero event-loop lag when a window recorded no samples
A sampling window that recorded nothing leaves the histogram empty, and an
empty IntervalHistogram reports its mean as NaN. Its percentiles return a floor
instead, which is why only the mean was affected and why this went unnoticed.

NaN then survives every arithmetic step in the sampler without complaint and
becomes visible only at the edge, where JSON.stringify renders it as null. So
/api/status served "mean_ms": null while nothing raised an error anywhere, and
any consumer of that gauge read null instead of a number.

Non-finite readings now report 0, which is the honest value: no samples means
no measured delay. Applied to every field so a later change to the histogram
source cannot reintroduce this one field at a time.

Found by CI rather than locally, because an idle window is far likelier on a
loaded runner with several test servers in flight. The failure was real; the
new tests establish the NaN premise and the null serialisation directly rather
than relying on that timing to reproduce.

ScreenTinker 792013e36c Record auth rate-limit rejections so they can be measured
The auth limiters are app.use middleware that return 429 before the handler
that writes activity_log, so a rejection left no trace anywhere — the limit
suppressed the record of itself. Four production IPs sit at exactly ten logins
a minute and there was no way to tell whether that is one attacker or an office
whose staff share an egress address, which is the difference between the
limiter working and the limiter locking out customers.

The rejection count does not answer that. The number of distinct accounts per
IP does: one account hammered is the limiter doing its job, several accounts
each denied a few times is a shared egress. Both are now recorded, and a
platform-admin-only endpoint reads the tally back.

Identifiers are salted-hashed with a per-process salt and only ever counted, so
this cannot accumulate into a roster of a customer's addresses. Memory is
bounded per key and overall, and says when a count was capped rather than
silently undercounting.

Behaviour is unchanged: same status, same body, and the recording is wrapped so
telemetry can never break the limiter. A test asserts ten through then 429 with
the identical response shape, since a diagnostic that alters what it measures
is worse than none.

ScreenTinker a93f65b20a Only store a device fingerprint against a device that still exists
A player that reconnects after its row was deleted sends the id it still has
cached. device_fingerprints.device_id has a foreign key to devices(id), so
writing that id back fails the constraint. The throw was caught, which is why
this looked harmless, but the catch abandons the whole fingerprint block:
last_seen is not updated, the reinstall link is not made, and the settings
restore never runs. That restore exists specifically for the post-delete
re-pair, so the failure landed exactly where the feature was meant to help and
a re-paired panel came back with its orientation, name and playlist reset.

Production shows 37 of these, timestamped identically to the "sending unpaired"
log lines — the same event seen from the other side.

The incoming id is preferred, then whatever is already stored, and only an id
that still resolves is written; otherwise NULL, which the column allows and
which ON DELETE SET NULL already leaves behind. The INSERT path a few lines
below had this guard; the UPDATE was missed, and it is the one that fires.

Tests cover the deleted-id reconnect, that last_seen still advances, and that
live ids are unaffected. One asserts the raw unguarded statement really does
raise FOREIGN KEY constraint failed, and another asserts the guard is present
in the handler itself, since the others exercise a mirror of that statement.

Also ignores *.sqlite / *.sqlite3, which the existing *.db rules missed.

ScreenTinker 8f2195a6e3 Recover an unpaired player without needing a keyboard
A display panel usually has no keyboard and no pointer, so a recovery path that
waits for input is not a recovery path. When the server stopped recognising a
device, the player revealed the server-URL form — typing that cannot happen on a
screen-only panel — and hid the pairing section, which was the one thing that
would have rescued it. The screen then sat on "Device was removed from server"
until someone physically reloaded it, even though the player was still connected
to the right server and could have asked for a new code itself.

Both handlers now drop the stale credentials and reconnect on a short countdown.
Reconnecting re-registers with no device_id, so the server issues a fresh pairing
code and the existing registered handler puts it on screen. config.serverUrl is
known-good by construction — we are talking to that server at the moment we are
rejected — so there is nothing for a human to re-enter.

The URL field stays editable throughout, and typing cancels the countdown, so
someone who does have a remote and wants to repoint the player is not yanked
mid-edit. The countdown is the same helper the first-boot path already used,
lifted out and shared rather than duplicated; its input listener is bound once
at setup instead of per countdown, which would have stacked a listener each time.

The Android player already behaved this way (ProvisioningActivity repair mode);
this brings the web player in line.

ScreenTinker e9cf7801c3 Alert once per outage instead of once per dedup window
A display going offline is one event, but the alert loop re-evaluated every
still-offline device on each 60s tick, so the 2-hour dedup window re-qualified
the same outage over and over. One closed browser tab produced six "your
display is offline" mails overnight, and would have kept going to the 24h cap.

Repeat suppression now keys on devices.offline_alert_heartbeat: the heartbeat
value an alert was already sent for. A device can only come back by sending a
heartbeat, so a later outage always carries a later value and the marker
invalidates itself on recovery — no cleanup, no state to reset. Keeping it on
the row also fixes a second source of duplicates: the in-memory window used to
empty on restart and re-alert the whole offline fleet.

The window stays, doing the job it is actually suited to — bounding how often a
flapping device can alert — and is checked before the marker is written, so a
rate-limited alert is deferred rather than marked and dropped.

The backfill runs once, via schema_migrations rather than the migrations array:
statements there re-run every boot, and an IS NULL backfill would then swallow
the first alert of any outage beginning after the last restart. It marks
currently-offline devices as already-alerted so upgrading does not itself mail
about outages the owner has already been told about six times.

ScreenTinker 9bcdaacd2c Show every screen's schedule on one calendar
The week view could only answer "what plays on THIS screen". With one screen
at a time an empty grid is ambiguous — nothing scheduled, or the schedule
points at a different screen? That ambiguity is what a user actually hit.

Adds an "All screens" scope alongside the per-screen one. Every block now
names its target, with a stable per-target colour and a legend, so a full
grid stays readable.

The scope for all=1 comes from the request's resolved tenancy and is filtered
on nothing else, so the tenant boundary rests entirely on that resolution.
Tests pin both halves: an ordinary tenant gains nothing by naming another
workspace in the query string, and the platform-admin act-as path still
resolves the workspace it asks for — the two are easy to mistake for each
other, so they are asserted separately.

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 f4595f017a Validate kiosk style values as CSS rather than as HTML
Some checks are pending
CI / Unit tests (node --test) (push) Waiting to run
CI / OpenAPI spec lint (push) Waiting to run
CI / Android unit tests (Kotlin schedule evaluator vectors) (push) Waiting to run
CI / Boot smoke + version check (push) Waiting to run
The kiosk page interpolates style.fontFamily and style.background into a <style>
block, escaped with escapeHtml. That is the wrong tool twice over: it escapes
& < > " ' but not { } ;, and inside a raw-text <style> element the entities it does
produce are never decoded, so it neither contains the value nor renders it correctly.

A value could therefore close the declaration, close the rule, and append its own —
putting an attacker-chosen rule on every panel showing the page. There is no XSS,
since </style> stays unreachable, but a url() in an injected rule is an outbound
request from every display, which is a beacon and a cross-site tracking channel.

Both values are now checked structurally rather than against a value allowlist,
because background is a free-text field: linear-gradient(), rgb() and url() are all
legitimate and keep working. Only characters that could terminate the declaration or
open a new rule are refused, along with comment syntax (which can swallow the
declarations that follow) and control characters. font-family needs no parentheses,
so it gets a tighter allowlist.

Tests cover both directions — injection refused and falling back to the default, and
ordinary gradients, colours and font stacks passing through untouched.

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 b255f2bfe1 Resolve proof-of-play references instead of trusting the reported id
Players replay a cached playlist, so the id reported on play_start can outlive the
row it names. play_logs.content_id carries a foreign key to content(id), and the id
went straight into the INSERT — so deleting a piece of content made every subsequent
play of it throw, and the whole event was discarded by a catch that logged no
identifiers. On production this fired roughly 360 times in six hours and wrote zero
rows in 24h: Reports was recording nothing at all, for everyone.

Widgets had a quieter version of the same bug. play_logs.widget_id exists and was
never written, so a widget play could not be attributed even when it did insert, and
play_end matched on content_id alone and so could never close a widget's open row.

The reported id is now looked up before use and written to whichever column it
belongs to. An id matching neither degrades to null references rather than losing the
event — content_name still records what played. A play event for a device that does
not exist is still refused; that foreign key is a real invariant, not an obstacle.

play_end matches on either column, and breaks ties on id: started_at has second
granularity, so two plays inside one second tie on it and the wrong row could be
closed. The new tests caught exactly that as flakiness before it was pinned.

The catch now logs the event, device, content and zone. Without them this was
undiagnosable in production.

ScreenTinker 76a8a16130 Update sharp to 0.35.x, and repair the corrupt PNG fixture it exposed
sharp decodes uploaded files directly (lib/content-ingest.js, routes/content.js
both call sharp(file.path) on whatever a user uploaded), so its bundled libvips is
part of the request path rather than a build-time detail. Moves 0.33.5 -> 0.35.3,
libvips 8.15 -> 8.18.

Validated against the calls this codebase actually makes, because it is a major
bump: metadata() still reports EXIF orientation (1/3/6/8 all round-trip, which is
what lib/media-orientation.js exifSwapsWH and the rotation-aware dimensions depend
on), a bare .rotate() still auto-orients, and resize().jpeg().toFile() is unchanged.
png/webp/jpeg/gif/avif all still encode and decode, and malformed input still throws
rather than crashing.

The new libpng is stricter, which surfaced a latent problem in the AUTH-01 test: its
1x1 PNG literal had a corrupt IDAT chunk whose stored CRC did not match its data. The
old decoder accepted it; the new one refuses with "vipspng: libpng read error", so no
thumbnail was written and the content-gate assertions failed with a 404 that reads
like an auth regression. Replaced with a PNG whose every chunk CRC verifies. The
stricter decode is the correct behaviour and is kept.

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 59c536c923 Keep a solo widget mounted, and size its keyboard to the viewport
Two problems on a panel showing one fullscreen widget, both visible as flashing.

The player re-navigated the WebView every duration_sec. PlaylistController.next()
requests a playlist refresh between plays and playCurrentItem() re-issues the item
unconditionally, so a one-item playlist reloaded the same URL forever. The existing
dedupe guard only covers the playlist-update path, so it logged "not restarting"
AFTER the reload had already happened. On an interactive widget that also discarded
whatever the viewer had typed.

showWidget() is now idempotent: same URL with the widget already on screen returns
without re-navigating, and the cached URL is cleared at every media-type transition
so switching away and back still reloads. The refresh itself is untouched — schedule
re-evaluation and dayparting still run on the timer, and widgets keep refreshing
their own data client-side (directory-search polls its board every 30s and preserves
the current query). The web player already behaved this way via reevaluateHeldWidget;
this brings the Android player to parity.

Separately, the directory-search keyboard was laid out in fixed pixels for a
1920-wide viewport. A panel's CSS viewport is its resolution over its density, so a
1080p screen at 240dpi presents 1280x720 — where four rows of 56px keys took ~37% of
the height instead of ~24%, and the lone max-width:700px breakpoint never fired to
correct it. Key metrics are now clamped against vh. The clamp maxima are the previous
fixed values and both vh terms exceed them at 1080 tall, so a 1080 viewport renders
pixel-identically; shorter viewports scale down. The breakpoint no longer re-pins .key,
which would have undone the clamp.

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 dda6f5b41e fix(devices): authorize the screenshot route on the device's workspace
GET /api/devices/:id/screenshot returns a live picture of what a screen is showing, but
it was still authorized pre-tenancy: `device.user_id !== user.id`, with a role bypass
listing 'admin'/'superadmin'. Three consequences, all now covered by tests:

- `device.user_id &&` SHORT-CIRCUITED. A device with no user_id — never paired, or its
  owner deleted — skipped the ownership test entirely, so any authenticated account on the
  instance could read it. An unpaired panel displays its pairing code on screen, so that
  image is also a route to claiming the device (AUTH-10, out of scope here but connected).
- 'platform_admin' was absent from the bypass list. #14 renamed 'superadmin' to
  'platform_admin', so an actual platform admin fell through to the ownership test and was
  denied unless they happened to own the row.
- Workspace members other than the owner were denied a device they administer through
  every other endpoint.

Now uses accessContext() against the device's workspace — the same helper routes/devices.js
uses — which covers direct membership, org-level access and platform staff in one call. A
device with no workspace is denied outright rather than defaulting open.

Deliberately unchanged: the ?token= query-parameter mechanism on this route, which is a
separate finding with its own blast radius.

No response shape change: still 200 / 401 / 403 / 404 with the same bodies.

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 4b13dadb4d fix(logging): gate CF-Connecting-IP on a Cloudflare peer, not any trusted proxy
getClientIp() decides the value every per-IP control keys on — the auth/pairing rate
limiters, lib/pair-lockout, and activity_log.ip_address — so a caller must never be able
to choose it. It believed CF-Connecting-IP whenever the immediate peer was in the
`trust proxy` list, which includes loopback/linklocal/uniquelocal.

Those entries are correct for X-Forwarded-For: a proxy APPENDS to that header and Express
walks the chain right-to-left, so a client-supplied value cannot become the resolved
address. CF-Connecting-IP has no chain — a local reverse proxy passes through whatever
single value the client sent — so treating a loopback peer as evidence the request came
through Cloudflare means trusting the client.

Gate it on the published Cloudflare ranges alone. This is also the portable behaviour:
most self-hosted installs are not behind Cloudflare, and for them the header is now
simply ignored, with attribution falling back to req.ip under whatever `trust proxy` the
operator configured. Installs that do front with Cloudflare are unaffected — their peer
really is a CF edge.

Documented the distinction at config/cloudflareIps.js so the two lists are not conflated
again. No response shape or DB change; no client impact.

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 c4b5a8679e refactor(auth): centralise session token resolution across manual verify sites
Six places verified a session JWT inline instead of going through requireAuth,
each repeating a slightly different subset of its checks. Introduce
resolveSessionUser() in middleware/auth.js as the single definition of "this
token is a usable session, and here is whose it is", and route all of them
through it: the three /api/status token routes, the screenshot route, the
content-reference gate, and the /dashboard socket handshake. requireAuth is now
a thin wrapper over the same helper, so the two cannot drift.

Also:
- Give the pre-TOTP token a distinct audience so it is redeemable only through
  verifyMfaPendingToken (POST /api/auth/totp/verify). verifyToken refuses any
  token carrying an audience, so a token minted for one purpose cannot be
  redeemed on another path.
- The dashboard socket handshake now takes userId/userRole from the live users
  row rather than from the token claim, so role changes take effect on the next
  connection instead of riding the token's remaining lifetime.
- Add test/session-token-resolution.test.js covering all six surfaces,
  including the socket handshake.

Every call site keeps the status code and error body it returned before.
Net query cost: the content-reference gate and the socket handshake each gain
one users-by-id lookup (the same one requireAuth already does per request); the
other four are unchanged or replace an equivalent lookup.

In-flight pre-TOTP tokens are invalidated by the audience change; they live 5
minutes, so the window is a re-login at worst.

fix(subscription): make the trial-expiry auto-downgrade actually fire (#228)
getUserPlan()'s auto-downgrade was guarded on `subscription_status !== 'active'`,
but that column DEFAULTs to 'active' and is only ever changed by Stripe webhook
events. For trial users who never touch Stripe — the entire population it's meant
to catch — the condition was always false, so the downgrade never ran and every
signup kept Pro free forever.

Re-key the guard on the real signals:
  - trial expired (!trial_active), AND
  - stripe_subscription_id IS NULL (never paid), AND
  - plan_id === trial_plan (still on the plan the trial granted), AND
  - plan_name !== 'free'

The plan_id === trial_plan clause is load-bearing: it protects comped / hand-
granted plans (e.g. a manually-set enterprise plan, where plan_id !== trial_plan)
from being silently downgraded. Grandfathered accounts (trial_started IS NULL)
never enter the block at all, so the ~home cohort is untouched. Added a comment
documenting the subscription_status-default trap so it isn't reintroduced.

Enforcement stays forward-only/lazy — the downgrade happens in the resolver on a
user's next request; no mass update here.

Downstream (deviceSocket.checkDeviceAccess, traced, unchanged): a genuinely-
expired free-tier trial now resolves to free and its device-limit block correctly
caps it to 1 device; grandfathered home (2 devices) and paid users are not
blocked. NOTE: the separate "Trial Expired" screen branch there is a pre-existing
dead condition (it needs trial_started set AND plan_name='free' at once, but the
downgrade clears trial_started) — left as-is per scope; flagged for follow-up.

Tests (new trial-expiry.test.js — there was none, which is how this shipped):
lapsed trial downgrades; comped enterprise (plan_id!=trial_plan) not downgraded;
grandfathered home (trial_started NULL) not downgraded; paid user not downgraded;
in-window trial not downgraded; plus a regression pinning that subscription_status
='active' no longer shields a lapsed trial. Suite 563/563.

CI / Android unit tests (Kotlin schedule evaluator vectors) (push) Waiting to run

Add allow_promotion_codes: true to the checkout.sessions.create call in
POST /checkout. This is what renders the "Add promotion code" field on Stripe's
hosted checkout page; for API-created sessions there is no Dashboard equivalent
(that toggle only exists for Payment Links, which we don't use), so a comment
warns against removing it as "redundant". The billingPortal branch is untouched
— portal sessions handle discounts separately.

Testing: no Stripe-SDK test/mock existed (the billing-*.test.js files cover the
#146 usage-metering path, not Stripe). Added stripe-checkout.test.js using the
repo's in-process router-mount convention with a minimal `stripe` stub injected
via require.cache, asserting the checkout payload carries
allow_promotion_codes:true (and still builds a subscription session for the
requested price). Full suite 557/557.

feat(content): subtitle/caption support as a content property (#223)
Subtitles/captions are set once in the content library and applied
automatically by the player — no in-player controls (the player stays bare).

- DB: 4 new content columns (captions_enabled, captions_lang for YouTube;
  subtitle_url, subtitle_lang for uploaded videos), all default off/NULL.
- buildSnapshotItems: denormalize the 4 fields into published_snapshot so the
  player receives them (enumerated query).
- content.js PUT: accept the 4 fields (subtitle_url only clearable here).
- POST /:id/subtitle: dedicated .vtt uploader (separate multer, since the main
  filter is video/image-only); stores the file in the content dir, records
  subtitle_url + subtitle_lang. Old subtitle file replaced; DELETE cleans up
  the sidecar.
- Player: YouTube -> loadModule('captions') + setOption(...languageCode) in
  onReady (best-effort, wrapped). Uploaded video -> a <track kind="subtitles">
  appended to the <video>, forced mode='showing' on load (same-origin, so
  CORS-clean like the video).
- Edit modal: YouTube gets an enable-captions checkbox + language; uploaded
  video gets a .vtt file picker + language + a remove-subtitle option. en/es.

Honest limitation (in the PR): YouTube caption control via the IFrame API is
undocumented/version-dependent and only works if the video actually has
captions — hence best-effort and wrapped so it can never break playback.

Test: content-subtitles.test.js — the 4 fields survive publish -> snapshot,
the .vtt upload endpoint stores + records the file, and a non-.vtt is rejected.

feat(content): batch operations — multi-select, batch delete, batch move (#224)
The content library had no batch operations — every item was managed one at a
time. Add multi-select with batch delete and batch move.

Backend (content.js):
- POST /content/batch/delete — array of ids, atomic: validates + authorizes
  EVERY id first (malformed/missing/forbidden rejects the whole batch), then
  deletes in one transaction. Reuses the single-delete teardown.
- POST /content/batch/move — array of ids + target folder_id, same atomic
  validate-all-first; target folder must share each item's workspace. Folder is
  organizational (not in the snapshot), so no device push.
- Refactor: extract purgeContentRow() (file removal + snapshot scrub + row
  delete + affected-device collection) and pushContentUpdates(); DELETE /:id now
  uses them, so single + batch share one scrub path (no duplication). Add a
  boolean contentWritable() mirroring checkContentWrite's authorization.
- 500-item cap per batch; UUID validation guards the snapshot-scrub LIKE.

Frontend (content-library):
- Per-card selection checkbox, select-all/none (visible), shift-click range.
- Selection persists across folders/pages (issue-aligned cross-page selection);
  cleared after a successful batch op.
- Batch toolbar (shown when >0 selected): count, move-to-folder picker, delete
  with click-again confirm. Selected cards get an outline.
- api.batchDeleteContent / batchMoveContent; en/es i18n.

Not included: batch "set expiry" (listed in the issue's toolbar sketch but only
delete/move had endpoint specs) — deferred; PUT already does per-item expiry.

Test: content-batch-ops.test.js — batch delete removes rows+files+scrubs
snapshots; atomic rejection leaves valid rows intact; malformed id -> 400;
batch move reassigns folder; cross-workspace folder refused; empty batch -> 400.
Suite 553/553.

Uploading N files fired N sequential XHRs (one POST per file). Select-many now
goes up in a single request.

- Server POST /api/content: upload.array-style `files` field (up to 20) via
  upload.fields, looping ingestUploadedFile per file. Keeps the legacy single
  `file` field so older clients / API callers are unaffected. Response shape is
  backward-compatible: a single file returns the content object (what every
  existing caller reads), a batch returns the array.
- api.uploadContent: accepts a File, FileList, or array; appends all under
  `files`; aggregate upload progress; resolves to object (single) or array
  (batch).
- content-library handleFiles: one batched request with aggregate progress and
  a "N files uploaded" toast instead of a per-file loop.
- en/es i18n for the count-based progress/toast strings.

checkStorageLimit is left as-is — it's a coarse pre-gate (blocks only when
already at/over the limit), same as before; per-file aggregate sizing was a
listed "consideration", not required, and is out of scope here.

Test: content-multi-upload.test.js drives the real router+multer over HTTP —
3-file batch creates 3 rows and returns an array, legacy single `file` returns
an object, single `files` returns an object, empty -> 400. Suite 545/545.

feat(content): server-side search, type filter, and sort (#221)
Content discovery was client-side only, scoped to the items already rendered
on the current page — searching "logo" on page 1 couldn't find logos on page
2 or in another folder.

Server (GET /api/content):
- ?q= text search on filename (LIKE, workspace-wide — a search ignores the
  open folder so nothing is missed). LIKE metacharacters are escaped so a
  filename with % or _ matches literally.
- ?type=video|image|youtube|web — youtube (video/youtube) and web (other
  remote_url) are split from plain uploaded video/image so the four UI buckets
  map cleanly.
- ?sort=date_desc|date_asc|name|size — whitelisted (never interpolates user
  input into ORDER BY); default keeps the legacy newest-first ordering.

Frontend (content-library):
- Type filter + sort dropdowns; search debounced (300ms) and now hits the
  server instead of filtering the DOM.
- Result count shown while a search/type filter is active.
- en/es i18n.

api.getContent gains an opts arg ({q,type,sort}); folder_id is omitted while
searching to match the server's workspace-wide behaviour.

Test: content-search-filter-sort.test.js mounts the real router and covers
substring match, LIKE-escape (literal %), the type buckets, name/size sort,
the ORDER BY injection guard, and combined filters. Suite 541/541.

On Android TV with weak/unstable WiFi, YouTube embeds auto-select 1080p+
and buffer/stall. Add a per-item "Unstable connection" flag that biases the
YouTube embed toward a 720p ceiling.

- DB: content.unstable_connection INTEGER NOT NULL DEFAULT 0 (non-destructive,
  existing rows unchanged).
- buildSnapshotItems: denormalize the flag into published_snapshot so it
  reaches the player (that query enumerates columns, so it had to be added
  explicitly — covered by a new test). preview-payload reuses the same query.
- content.js PUT: accept + coerce unstable_connection to 0/1.
- Player: playerVars.vq='hd720' + best-effort setPlaybackQuality('hd720') in
  onReady when the flag is set. Both are hints YouTube may still override, but
  together they bias the initial selection down to 720p.
- Edit modal: YouTube-only checkbox + hint; en/es i18n.

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.

* fix(widgets): directory board — logo replaces title, and images load on the player

Two on-screen bugs on the directory board:

1. A logo did not remove the title text — both rendered, stacking the wordmark over
   the name. renderDirectoryBoard (and the directory-search header) now gate the title
   h1 behind !logoSrc, so a logo replaces the title. New render test guards it.

2. Logo + background images did not show on the player (NS_ERROR_DOM_CORP_FAILED,
   0 bytes). The player embeds widgets in a sandbox="allow-scripts" (opaque-origin)
   iframe, so /api/content image requests are cross-origin, and the helmet default
   Cross-Origin-Resource-Policy: same-origin blocks them. Set CORP: cross-origin (+
   ACAO:*) on the content file + thumbnail routes, matching the existing /uploads/content
   static route. Content already serves publicly, so no new exposure. Verified in a real
   sandboxed iframe: same-origin blocks, cross-origin loads.

The Tizen .wgt player black-flashed between IMAGE items on slow decode HW
(Samsung OM55B / SSSP). Root cause: playCurrent() called clearStage() before
renderImage() set img.src, so the stage was empty (black) until the new image
decoded. Images had no decode-gated double-buffer — video gained one in #167
(938a43a), which made the always-present image flash conspicuous by contrast.
renderImage has been byte-identical since the first Tizen commit, so there was
nothing to revert; the buffer had to be ADDED, mirroring the video path.

- preloadImage()/_takePreloadImage()/_releasePreloadImage(): one-ahead,
  image-only decode-gated buffer modeled on preloadVideo()/_takePreload().
  Detached <img>, src set, warmed via HTMLImageElement.decode() (feature-
  detected — onload/complete fallback for Tizen 5.0 / SSSP6). Warmed when the
  current image begins its dwell and from the group-sync boundary tick.
- renderImage now SWAPS: take the pre-decoded <img> (or decode a fresh one) and
  only THEN clearStage()+append, in one synchronous block — the compositor
  never sees an empty stage. Never clear-then-load on the image path.
- Scoped to images only: playCurrent() skips the up-front clearStage() solely
  for image targets (same branch order as the dispatch); video/youtube/widget
  keep their pre-dispatch clear untouched. onerror and decode() rejection route
  to skipSoon(); stale-index guard blocks mounting a stale decode over the
  current item after next()/gotoIndex/load(); one-ahead with stale release on
  index move, load(), stop(), and group-sync exit. #A1 single-item heal intact.

Tests:
- server/test/tizen-image-blackflash.test.js (new, 4/4): loads the real
  player.js in a vm context with a test-controllable decode() Promise and proves
  the invariant — across image->image the #stage is NEVER without a mounted
  <img> (old element held until the new image's decode()/onload resolves, then
  swap). Covers decode() supported, decode() absent (onload fallback), and
  broken-image (decode-reject / onerror) -> skipSoon. Proven to VIOLATE on the
  old clear-then-load ordering and HOLD on the fix.
- server/test/pip-overlay.test.js: the decode-gate makes image mount async,
  which broke its older shim (no decode()/onload/complete). Teach the shim
  element complete/naturalWidth so renderImage takes its synchronous
  complete-fallback branch and mounts. Test-only.

Full server suite 486/486. node -c clean. Headless proves the DOM ordering
invariant (the flash's precondition); final black-frame sign-off needs a real
OM55B panel (manual steps in the test-file header).

fix(pairing): close deferred-offline reclaim race + idempotent same-code adopt (#192)
A fresh unclaimed player that reconnects (same fingerprint) INSIDE the server's
~5s deferred-offline grace hit a false 'active on another connection' reclaim
reject, then collided on UNIQUE(devices.pairing_code) on the fall-through INSERT
and wedged unclaimed with no content. Real trial customer (web player) hit it.

server/ws/deviceSocket.js:
- Fix A (guard): gate the liveConn reclaim reject on !inDeferredOffline
  (pendingOfflines.has(id)). A device mid-deferred-offline is a zombie, not live,
  so a same-fingerprint reconnect is a legit reconnect, not a hijack. A genuinely
  live socket (never disconnected -> no pending-offline) still rejects a cloned
  fingerprint -> anti-hijack boundary preserved (documented).
- Fix B (idempotency): when the unclaimed old row holds the SAME pairing_code the
  reconnecting player presents, ADOPT/refresh it (mirror the claimed-reclaim path,
  but no device:paired) instead of INSERT-colliding. Differing-code case unchanged.
- deferOffline is NOT shrunk (it exists to prevent transient-blip flapping).

server/player/index.html:
- The cold-boot flap source: an unfiltered pageshow handler ran verifyLivenessSoon()
  on every load, opening+registering a socket early, which the boot connect() then
  tore down and rebuilt (connect->register->disconnect->reconnect). Guard it with
  ev.persisted (mirror the pagehide guard) so only real bfcache restores trigger it.

server/test/pairing-race.test.js:
- Forces the race against the real socket server (log-gated reconnect inside the
  deferred-offline window), asserts no false reject / no UNIQUE collision / single
  claimable row; + a hijack case asserting a cloned fingerprint on a genuinely-live
  display is still rejected. Web- and android-shaped fingerprints. Fails 2/4 on
  pre-fix code, 4/4 with the fix.

fix(content): render YouTube Shorts in 9:16 instead of a landscape frame (#184) (#189)
Vertical Shorts were played in a player forced to 100%x100% on a landscape
frame, so they looked wrong (pillarboxed/small). Option A: detect vertical at
ingest, persist it, and have every player honor it.

- Ingest (routes/content.js): detect a Short from the /shorts/ URL form OR
  portrait oEmbed dims (oEmbed now queried with the ORIGINAL url so /shorts/
  reports its true dimensions), and persist it as st_aspect=vertical on the
  stored embed URL. That's the only signal players get (remote_url), so it must
  be captured at ingest, not re-derived per loop. YouTube ignores the unknown
  param; players read the video id, not the full URL, to build the embed.
- Players read st_aspect=vertical and center a 9:16 box (fills a portrait screen,
  pillarboxes cleanly on landscape) instead of 100%x100%:
  web (player/index.html), Android (WebViewSupport.youtubeEmbedHtml), Tizen
  (player.js single-zone + zone paths). Dashboard library uses a static thumbnail,
  so it's unaffected.

Not doing Option B (yt-dlp): runtime dep + storage/bandwidth + maintenance +
YouTube ToS; embed-disabled Shorts already skip gracefully.

Tests: youtube-shorts.test.js (4) — /shorts/ and portrait-dims tag vertical,
landscape stays untagged, /shorts/ tags even if oEmbed fails. Android compiles;
web player inline JS + Tizen player.js parse.

Note: pre-existing Shorts added before this aren't retagged (would need an oEmbed
backfill) — re-add to fix, or a follow-up migration.

feat(widgets): directory-search widget (interactive search of a directory board, live-sync) (#188)
Some checks are pending

CI / OpenAPI spec lint (push) Waiting to run
CI / Android unit tests (Kotlin schedule evaluator vectors) (push) Waiting to run
CI / Boot smoke + version check (push) Waiting to run
* feat(widgets): add directory-search widget

An interactive, walk-up search view of an existing directory-board. It
references a source board by id (no data copy), so a venue can run the
scrolling board on a main screen and a search view on a tablet, letting
people find an entry instantly.

Server (routes/widgets.js):
- register 'directory-search' + renderDirectorySearch(): resolves the source
  board, inlines its categories as one \u003c-guarded JSON blob, renders all
  text via textContent (XSS-safe), live case-insensitive filter over
  identifier/name/subtitle (debounced), grouped results, available styling,
  optional touch on-screen QWERTY keyboard that drives the same filter path.
- missing / non-directory-board source -> friendly full-page fallback, not a 500.
- live-sync while open is out of scope; left a // TODO for a poll hook.

Frontend editor (views/widgets.js): type + magnifier icon, source-board
dropdown (from loaded widgets, filtered to directory-board), title, logo
(reuses the board's picker), placeholder text, theme, on-screen-keyboard toggle;
getConfigFromForm case. i18n: widget.dirsearch.* + type keys in en/es/it/de/pt/fr.
docs: openapi widget_type enum. Tests: server/test/directory-search.test.js.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* feat(widgets): live-sync for directory-search (poll source board, no reload)

Reflect directory-board edits on an open directory-search page without a reload.

- New public GET /api/widgets/:id/data.json returns { categories } for a
  directory-board (404 for missing/wrong-type so the page keeps last-good data
  on a transient miss). CORS-open (ACAO:*) + no-store so a null-origin sandboxed
  widget iframe can read it; exposes only data already public via /render.
  Exempted from CSP + auth in server.js alongside /render.
- directory-search page inlines its source_widget_id and polls the board's
  data.json every 30s via a relative URL (works behind a proxy/base path and
  from a null-origin iframe). Only rebuilds + rerenders when the data actually
  changed, so a mid-search view isn't disturbed; skips while document.hidden;
  keeps last-good data on any fetch error. Flatten logic factored into
  buildFlat() and reused by the poll.

Tests: data.json feed (categories, CORS header, 404s) + poll wiring in
directory-search.test.js (13/13). Verified live in a browser (page.clock
fast-forward): editing the board updates the search page with no reload.

* fix(android): let player WebViews take touch focus for interactive widgets

directory-search is served through the existing generic widget path
(loadUrl <server>/api/widgets/:id/render), so it already renders on Android
with JS + DOM storage + mixed-content enabled, same-origin (so its live-sync
fetch of the source board's data.json works), and no touch blocking.

Add isFocusable/isFocusableInTouchMode to the shared WebView config so the
search field reliably takes a tap/cursor inside the kiosk lock-task WebView.
Harmless for passive widgets (board/YouTube have no focusable inputs); the
widget's own on-screen keyboard still drives the filter when the system IME
is suppressed. Verified with :app:compileDebugKotlin.

fix(pairing): reinstalled panel reclaims its device row instead of being blocked [Bold] (#180)
Bold Media Group's fleet broke on the 1.9.3->1.9.6 upgrade. Their MDM does an
uninstall/reinstall (app data wiped), so the player registers with
{ pairing_code, fingerprint } and NO device_id and shows a pairing code — but the
dashboard reported "code does not exist". Deleting the device_fingerprints row fixed
it, which pinpointed the fingerprint-reclaim guard in server/ws/deviceSocket.js.

Root cause: the reclaim guard was
`stillAlive = !!liveConn || secondsSince < reclaimSettleSeconds; if (stillAlive) reject`.
On an in-place reinstall the old row heartbeat seconds ago, so `secondsSince < 300` is
ALWAYS true -> it emitted device:auth-error and returned BEFORE the pairing_code INSERT,
so the code the player displayed never existed server-side.

The settle window's real purpose was to REMATCH an existing fingerprint back to its
device row on reinstall — not to force a fresh re-pair. So the fix keys off claim status,
not the timer (server-only; no APK change — reviewed and confirmed unnecessary):
- Reject ONLY when the old row has a genuinely LIVE socket (liveConn) — the real anti-
  hijack boundary. Unchanged.
- CLAIMED old row (user_id set) -> RECLAIM it regardless of the settle window: reuse the
  row, rotate the token, emit device:registered{online} + device:paired. The panel returns
  straight to paired (no operator re-pair, no orphaned duplicate row), preserving name /
  claim / playlist / content. device:paired drives the app off the pairing screen, so the
  fresh code it showed is irrelevant.
- UNCLAIMED old row -> fall through to the pairing_code path and PROVISION FRESH with the
  shown code (reclaiming would leave a stale/null code -> "code does not exist"). #150
  relinks the fingerprint to the new row.
`reclaimSettleSeconds` is now vestigial for this path. Trade-off: a fingerprint-only reclaim
of a CLAIMED-but-offline device is no longer delayed ~300s — not a new attack class (the old
code already granted it once the window elapsed); liveConn remains the hard boundary. Truly
closing that window without a re-pair needs client keystore attestation (a future APK).

Also fixes a latent crash this newly exercises: middleware/subscription.js getUserPlan()
dereferenced an undefined user in its else branch ("Cannot set properties of undefined
(setting 'trial_active')") when the user/plan JOIN missed. Under the claimed-reclaim path
that ran checkDeviceAccess->getUserPlan, the throw was swallowed by the reclaim try/catch and
silently dropped the device to provision-fresh. Guard: `if (!user) return null`.

Tests (server/test/fingerprint-reclaim.test.js):
- NEW: a CLAIMED reinstall reclaims the SAME row, emits device:paired, creates no duplicate,
  keeps the fingerprint linked — regardless of the settle window (the Bold repro, fixed right).
- NEW: recent heartbeat + no live socket, UNCLAIMED -> provisions fresh with the shown code.
- NEW: a LIVE old socket still rejects and creates no new row (security preserved).
- Updated the #143 gone-device test to expect provision-fresh for an unclaimed row, and the
  log-noise assertion to the "reclaim rejected" message.
465/465 server tests pass. Server-only: NOT deployed, no version bump, Android untouched.

feat(email): SMTP transport as an alternative to Microsoft Graph [#173] (#179)
Adds a pluggable email transport so self-hosters without Azure/M365 can send
mail through any standard SMTP server (Postfix, Gmail, Mailgun, SendGrid, corp
relay). Graph stays the default; behavior is byte-for-byte unchanged when
EMAIL_TRANSPORT is unset or "graph".

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

462/462 server tests pass. Boot verified for all four states (configured,
misconfigured, invalid, default).

Closes #173

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.

test(ci): OS-assigned ephemeral ports for subprocess suites — kill the port-collision flake (#176)
The subprocess-booting test suites hand-picked fixed ports in a cramped ~3955-4021 range, and
156-schedule-read-path deviated to a RANDOM port (3900 + rand%90) that overlapped those fixed
ports. Under CI load two servers could race on the same port, surfacing as flaky "no such table:
devices" / "FOREIGN KEY constraint failed" (a server answering a request against a half-migrated
or wrong DB). It's environmental — the suites pass locally and in isolation.

Fix: a shared test/helpers/free-port.js (bind :0 on loopback, read the OS-assigned port, release)
called in before() so every suite gets a guaranteed-unique ephemeral port — concurrent suites can
no longer collide, and no one has to hand-assign ports.

- Codemod converted 30 suites: const PORT = <fixed|random> -> let PORT (+ BASE) assigned via
  `PORT = await freePort()` at the top of before().
- 3 hand-fixed (different structure): 148-eviction-storm (lowercase `base`), boot-health (no
  before() — allocates PORT + a throwaway SEED_PORT inside the test, replacing the hardcoded
  3894), totp-keyrotation (no before() — allocates at the test start before bootServer()).

No fixed 39xx/40xx ports remain. Full server suite 435/435; the 4 hand-touched suites pass in
isolation. Pure test-infra change — no app code touched.

CI / Android unit tests (Kotlin schedule evaluator vectors) (push) Waiting to run
CI / Boot smoke + version check (push) Waiting to run
* fix(content): rotation-aware media dimensions — portrait no longer stored landscape (#170)

Ingest recorded CODED width/height and ignored rotation, so a portrait phone video
(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.

* feat(group-sync): synchronized playback per group (server + Android) [stage 1]

Play a group's shared playlist in lockstep across its displays — start/end items
together — by reusing the video-wall sync primitive with the spatial transform
removed and keyed on group_id instead of wall_id.

Server:
- device_groups += sync_enabled + leader_device_id (optional pin).
- buildPlaylistPayload emits a group_sync:{group_id, is_leader} block ONLY for a
  member whose playlist matches the group's shared playlist (playlist-match guard —
  a mismatched member is ignored, never synced). Membership via device_group_members.
- Leader auto-election: pinned-if-online -> first online matching member -> stable
  fallback; computed (never persisted, so the operator's pin is preserved).
- group:sync / group:sync-request relay among eligible members (mirrors wall:sync,
  guarded on membership + playlist match).
- Self-heal: re-push payloads to group members on (re)connect so is_leader refreshes.
- PUT /api/device-groups/:id accepts sync_enabled + leader_device_id and re-pushes.

Android:
- WallController is now mode-aware. WALL = transform + object-fit:fill + forced
  follower-mute (UNCHANGED — every wall branch is byte-equivalent when isGroup=false).
  GROUP = same leader/follower timing incl. the full video drift controller, but
  full-screen (no transform), normal fit, and per-item mute honored (no forced mute).
- WebSocketService: emitGroupSync/emitGroupSyncRequest + onGroupSync/onGroupSyncRequest.
- MainActivity: dispatch emit by mode, parseGroupConfig, onPlaylistUpdate group hook.

Wall path is provably unchanged (additive mode, defaults to WALL). Kotlin compiles;
server suite 407/407.

Stage 2 (follow-up): web + Tizen parity, dashboard sync toggle + leader picker,
offline-sweep leader promotion.

* feat(group-sync): web + Tizen player parity [stage 2]

Mirror the Android group-sync generalization in the two web-based players so a group
with a shared playlist syncs across mixed player types, not just Android.

Web player (server/player/index.html):
- group:sync / group:sync-request handlers (index jump + latency-compensated video
  drift, same maths as wall:sync) — no audio policy here, per-item mute honored.
- emitGroupSync() + applyGroupSync() (4Hz leader broadcast; follower sync-request).
  NO CSS transform, NO forced mute (unlike applyWallMode).
- isFollower now also true for a group follower (suppresses self-advance).
- handlePlaylistUpdate handles data.group_sync (mutually exclusive with wall).

Tizen (tizen/js/player.js WallController + app.js):
- WallController is mode-aware: WALL styles the slice + forced follower semantics
  (UNCHANGED when mode !== 'group'); GROUP clears any wall styling (full-screen) and
  drives leader/follower timing only. syncId()/clearStageStyle() helpers; emitSync/
  onSync/onSyncRequest key the event + id off the mode.
- app.js: group:sync/request socket handlers; onPlaylist enters group sync on a
  group_sync block, else exits — content renders through the normal single-zone path.

Realigned the v4-exit-signal-phase3 TIZEN slice (682->696) shifted by the app.js edits.
Wall path is provably unchanged in both (additive group mode). Server suite 407/407;
both players' JS parse.

* feat(group-sync): dashboard UI — sync toggle + leader picker [stage 3]

On each group's header row:
- "Sync" checkbox -> PUT /api/groups/:id { sync_enabled } enables synchronized
  playback; server re-pushes to members so they enter/exit sync mode. A hint notes
  it needs a group playlist and that a display on a different playlist is ignored.
- When on, a "Leader: Auto / <display>" picker -> { leader_device_id } (null = auto-
  elect, which self-heals; or pin a specific member to always lead when online).

Adds api.updateGroup(id, data) and the en i18n strings (en-only, mirroring the
existing per-group UI keys; the i18n parity test is apitoken-scoped).

Frontend parses (ESM); server suite 407/407.

* feat(group-sync): rework to clock/schedule sync + double-buffer + polish

Replace the leader/follower relay model with clock/schedule sync. Every
same-playlist member derives the identical (index, position) locally from a
server-disciplined clock + the deterministic playlist schedule, so sync:
  - needs no server at play-time (offline-native), and
  - has no leader role to double-elect (kills the split-brain class the leaked
    WallController tick produced).

Server
  - heartbeat-ack now carries server_ms + echoes client_ms for NTP-style clock
    discipline; the client caches the offset (survives an outage).
  - POST /groups/:id/resync -> group:resync (manual "Resync now").
  - (kept: group_sync payload; leader machinery is now vestigial/ignored.)

Clients (web / Tizen / Android)
  - Clock offset disciplined over the heartbeat, cached (localStorage / prefs).
  - Schedule engine: pos = (syncedNow mod Sum(duration_sec)) with a CANONICAL
    slot formula identical across platforms so mixed-platform groups can't drift.
  - Snap-on-load: a fresh clip hard-seeks ONCE to the exact position (was ~5s of
    gentle nudge to eat a ~0.3s load offset); steady-state keeps the gentle nudge.
  - Double buffer: warm the next clip a few s before the boundary -> instant
    switch, no black hold. Android pre-decodes on a throwaway surface so the swap
    doesn't flash one wrong-aspect (landscape-stretched) frame.
  - In-place duration edits: duration_sec dropped from the change signature and
    applied in place, so a duration edit re-anchors the schedule WITHOUT a restart.
  - Live-log shows discrete corrections (jump/align/seek) immediately; only the
    steady-state line is throttled.

Android
  - Fix leaked WallController leader tick: onDestroy() now stops it (Handler on the
    main looper outlived the Activity -> zombie broadcaster / split-brain).

Dashboard
  - Group leader picker -> "Resync now" button.

Tests: heartbeat-ack clock fields + resync route; exit-signal .wgt slice realigned.

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.

feat(ota): self-update kill switch — global, per-device, and MDM auto-detect (#166)
Lets an operator (or an MDM) own updates instead of the app self-installing, which
on managed panels shows a self-install confirm dialog over customer content
(#155). Three layered controls:

- GLOBAL (server): config.otaEnabled from OTA_ENABLED (default on). When off,
  /api/update/check returns update_available:false, reason:ota_disabled_global —
  the whole instance stops offering updates.
- PER-DEVICE (server + dashboard): new devices.ota_enabled column (default 1). When
  0, that device is never offered an update (reason:ota_disabled_device). A
  "Self-update (OTA)" toggle in the device settings flips it via PUT /api/devices/:id.
- AUTO-DETECT (Android): UpdateChecker stands down entirely when a foreign device
  owner (an MDM/DPC) manages the panel — detected via getActiveAdmins() + not being
  device owner ourselves. Pure client-side, errs safe, needs no server change.

The two server gates are enforced server-side so they cover EVERY client version,
not just ones with the client-side stand-down. When OTA is off the device still
reports its version (dashboard sees state); the MDM/operator owns the actual update.

For an MDM-managed fleet (e.g. Pivot/MAXHUB), turn OTA off and let the MDM push the
APK — the install-dialog race disappears from every angle.

Tests: +2 (per-device gate + a real OTA_ENABLED=false server for the global gate);
full server suite 393 pass; Android compiles.

The v4-exit-signal-phase3 tests eval a hardcoded LINE RANGE out of tizen/js/app.js
(harness(TIZEN, 663, 697)). The #162 stage-owner fix inserted ~19 lines above that

ScreenTinker e0b45bf907 fix(playlists): return item schedules from GET /:id so the editor shows them (#156)
GET /:id built the items array but never called schedulesForItem, so the playlist
editor rendered "always plays" for items that have a live schedule. Because the
editor re-PUTs whatever it loaded and PUT .../schedules is a wholesale
DELETE+INSERT, an unchanged save on a mis-loaded item silently wiped the real
schedule. Mirror GET /:id/items:351 so the read path returns the blocks the
editor and player already agree on.

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 09e11397b4 test: widen CI-fragile event-loop-gap timing bars (flaky prune/storm asserts)
CI flaked on the 300k-row prune non-blocking assert: a healthy chunked prune hit a 417ms max
event-loop gap on a shared runner, over the strict 250ms bar (the same test passed on the prior
commit; the release bump changed no logic). These probes exist to catch a MULTI-SECOND freeze (the
pre-fix whole-table sort froze 40-48s) — not to enforce a sub-300ms latency SLA — so a strict bar is
fragile under runner contention/GC. Widen both to <1500ms: still << "seconds" (catches any real
regression) but robust on CI. No production code changed.

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 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 5ba5905637 fix(#146): web player — guard PlayerMediaHealth calls by METHOD, not object (stale-module TypeError)
Live error: "Uncaught (in promise) TypeError: PlayerMediaHealth.shouldShowIdle is not a
function" inside the device:paired socket handler.

WHAT WAS ACTUALLY WRONG: not a missing/misnamed definition — the module DOES export
shouldShowIdle (served + unit-tested). It's a VERSION SKEW: /player/* is served network-first
by the service worker, so a transient module-fetch failure falls back to the STALE cache (an
older player-media-health.js that predates shouldShowIdle) while index.html loads fresh with
the call. window.PlayerMediaHealth then exists but lacks the method, and the call site
guarded the OBJECT (`window.PlayerMediaHealth ? ...`) not the METHOD — so it threw, aborting
the rest of the device:paired handler (the showStatus after it was skipped).

FIX: guard the METHOD at both call sites (typeof X.method === 'function') so a stale/partial
module can never throw — it falls back to the safe inline default (!isPlaying for the idle
decision) and the handler runs to completion.

SIBLING (errors travel in pairs): the needsReattach call in the "Playlist unchanged" branch
had the SAME object-not-method guard. It was inside a try/catch so it couldn't throw uncaught,
but a stale module would silently skip the re-attach/hideStatus. Guarded it the same way.

No service-worker change needed: network-first already self-heals on the next good load; the
method-guard covers the transient/offline-fallback skew permanently.

Tests: player-media-health.test.js +1 module-surface test (both needsReattach and
shouldShowIdle are exported functions — catches the define-vs-call class). Inline player JS
syntax-checked; both guards verified present. Suite 319/319.

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

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 677b17028e feat(#146): billing:read scoped token — dual-path auth for the Usage Report (Option C)
Least-privilege way to read GET /api/billing/usage without requiring platform admin.
Additive + isolated: reuses the existing api_tokens scope system (the off-ladder 'agency'
scope is the precedent) and does NOT touch the shared role/permission checks other
endpoints rely on.

- New off-ladder scope 'billing:read' (routes/tokens.js SCOPES). Like 'agency' it is NOT
  on the read<write<full ladder, so tokenScopeGate rejects a billing token on every
  PUBLIC_ROUTER and JWT-only routers reject any st_ token -> the scope grants billing-read
  and NOTHING else.
- DUAL-PATH gate requireBillingRead (middleware/apiToken.js), written as an EXPLICIT OR:
  authorize if (billing:read token) OR (platform-admin session). Admins keep read access
  but are NOT required to; the token path doesn't lock out admins or vice versa. Billing
  route now mounted with bearerAuth (token OR JWT front door) + requireBillingRead (was
  requireAuth + requirePlatformAdmin).
- MINTING is platform-admin only (stricter than read/write/full/agency, which any
  workspace member may mint) since a billing:read token grants GLOBAL billing-read. Note:
  no finer "owner" tier exists here (#14 collapsed superadmin->platform_admin), so
  PLATFORM_ROLES is the top level required.

Tests (5, test/billing-authz.test.js): dual-path positive (token AND admin session both
200) + negative (user 403 / anon 401); scope isolation (billing token 403 on /api/devices,
401 on /api/admin; read token 200 on devices but 403 on billing); minting owner-only
(user + ordinary-admin 403, platform-admin 201); revocation -> 401. Existing token
firewall/partition suite (api.test.js) + billing-endpoint tests unchanged & green. Reused
the exact SHA-256 token-verification path (no bcrypt/new mechanism). Suite 306/306.

NOTE: spec described bcrypt + JSON `scopes` + an analytics:read precedent; this codebase
actually uses SHA-256 + a single `scope` TEXT column + 'agency' as the off-ladder
precedent. Implemented faithfully to the real system.

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

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

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

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

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

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

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

3. Admin toggle: GET/PUT /api/admin/status-debug (requirePlatformAdmin, mirrors the
   branding endpoints) + a checkbox in the Admin tab "Status endpoint" section
   (mirrors the branding checkbox). Takes effect on the next poll, no restart.

Tests: devices_connected always present+numeric and rises with a live socket (booted +
socket.io-client); debug present by default, admin flips OFF -> key omitted (loop_lag +
devices_connected remain) -> ON again, no restart; non-admin 403, anon 401; unit coverage
for getConnectedCount + app-settings default/override. Suite 289/289.

ScreenTinker fa3ab44c20 feat(#146): /api/status.debug throughput counters (gauges -> gauges + work done)
The debug block exposed only gauges (buckets, quarantined, inFlight) — state, not work.
A real flapping Firestick reads as flap.buckets:36, quarantined:0, indistinguishable
from healthy. Add lightweight in-memory throughput counters (total + last-completed
rolling window) so the server tells the flapper/flood story itself.

- lib/rolling-counter.js: shared bounded scalar counter (total, curWindow, lastWindow,
  windowStart); rolls lazily on bump AND read (no timer), idle decays to 0.
  DEBUG_STATS_WINDOW_MS default 60000.
- flap-limiter: refused{Total,LastWindow} (every allow:false), quarantineStarts{Total,
  LastWindow} (a quarantine event stays visible after the gauge decays).
- ota-breaker: stats() rateBackoff{Total,LastWindow}.
- ota-download-guard: servedTotal/shedTotal alongside the per-window values.
- database: maintenance sweepsTotal (confirm the prune is firing, not stalled).
- routes/status: debug block gains ota_breaker + the new fields (aggregate-only, cheap).

Tests: rolling-counter window-roll + idle decay; each counter increments on the right
event; booted /api/status asserts the new fields present + numeric. Suite 285/285.
Fallout doc: observability section lists the fields + what each tells a soak-watcher.

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

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

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

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

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

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

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

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

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

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

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

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

ScreenTinker 2f7133f8c8 fix(#146) A: non-blocking maintenance — chunked+yield+band-gate all sweeps
The death-spiral amplifier: pruneStatusLog ran a whole-table ROW_NUMBER() sort,
40-48s synchronous on the 1.1M-row incident table, freezing boot -> healthcheck
fail -> restart loop.

- lib/chunked-prune.js: shared chunkedDelete (rowid IN (SELECT ... LIMIT ?) since
  better-sqlite3 has no DELETE...LIMIT) — bounded batch + setImmediate yield between
  batches, optional band-gate. Core invariant: no sync op blocks >~50ms ever.
- pruneStatusLog: rewritten per-device via a loose index-scan seek
  (WHERE device_id > ? ORDER BY device_id LIMIT 1 — O(log n) each), retention +
  newest-cap trimmed in bounded batches, async, re-entrancy-guarded, band-gated on
  the interval / un-gated + fire-and-forget at startup so a bloated table self-heals
  on deploy WITHOUT freezing boot.
- heartbeat.js: maintenance moved off the interval body into async band-gated
  re-entrant runMaintenance(); play_logs + provisioning prunes chunked; offline-marking
  stays synchronous.
- pruneTelemetry: bounded single statement (OFFSET 6000 LIMIT batch), stays sync.
- idx_devices_provisioning so the provisioning prune batch subquery is an index range.

Tests: correctness (per-device cap + retention, independent devices), 300k-row backlog
trims in many batches with max event-loop gap <250ms, band-gate no-op while critical +
startup runs regardless, re-entrancy (concurrent -> once). Existing prune tests updated
to await. Suite 247/247.

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

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

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

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

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

ScreenTinker 81e7d58099 fix(#146): reconnect/heartbeat storm containment (beta5)
Second head of the OTA-loop root cause (#144), on the connection/heartbeat
layer: unbounded device-driven work with no circuit-breaker. Symptoms in Bold
prod — devices shown OFFLINE in CMS while online+playing, loop-lag simmer
(p99 300-1145ms), device_status_log grown to 1.1M rows.

False-offline (two causes, both fixed):
- evicted-socket re-arm race: evictPriorSocket runs before registerConnection,
  so the evicted old socket's disconnect armed a fresh offline timer for a
  just-reconnected device. Tag evicted socket ids and bail in the disconnect
  handler (ws/deviceSocket.js).
- heartbeat checker false-positive: a device with a live socket in /device is
  UP even if its in-memory lastHeartbeat is stale under lag; skip it instead of
  marking offline (services/heartbeat.js).

Storm containment:
- batched/coalescing device_status_log writer (lib/status-log-writer.js): net
  state per device per flush, breaking the storm->bloat->slow-write->lag loop.
- newest-N-per-device row-count cap in the global sweep (db/database.js): hard
  bound regardless of churn; trims the existing 1.1M backlog on the first sweep.
  Per-device prune unified to statusLogRetentionDays (was hardcoded 7d).
- reconnect-throttle idle-bucket sweep (lib/reconnect-throttle.js): the #142
  throttle already existed; added the memory-bound sweep it lacked (wired in
  server.js). No second breaker.
- cosmetic: cap the OTA breaker level counter (lib/ota-breaker.js).
- best-effort status-log flush on the crash path (server.js).

Tests: load harness (test/reconnect-storm-load.test.js) proves breaker engage,
clean offline-clear, no-throttle-on-normal-reconnect, batched writes, bounded
loop-lag; cause-1 re-arm race proven with teeth (test/evicted-socket-rearm.test.js).
Both mutation-checked (fail without their fix). Full suite 240/240.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

ScreenTinker 404c3301dd fix(#143): enforceable device block + fix the null-token auth short-circuit
Highest-priority #143 item (operator finding from Bold): nulling a device's token
did NOT lock it out — device 75c2a08a immediately reconnected and saturated the
loop. Two distinct defects:

1. Auth short-circuit (the cause). device:register used
     if (device.device_token && !validateDeviceToken(...)) { reject }
   so a NULL/empty STORED token made the guard falsy -> validation SKIPPED, and the
   next block even MINTED a fresh token and persisted it. Nulling a token thus
   RE-PROVISIONED the device instead of locking it out. Fix: drop the
   `device.device_token &&` guard -> `if (!validateDeviceToken(device_id, device_token))`
   (validateDeviceToken already returns false for null-stored/missing/mismatch), and
   remove the legacy "mint a token for a null-token device" path (the re-provision
   vector). An already-provisioned device (every row, incl. 'provisioning', is created
   WITH a token) presenting null/empty/invalid is now REJECTED + disconnected.
   The first-pairing seam is unaffected: a brand-new device has NO device_id and goes
   through the pairing_code branch (which mints id+token) — a different code path.

2. No server-side kill switch. Added a `blocked` column (devices.blocked INTEGER
   NOT NULL DEFAULT 0; schema.sql + a database.js migration). The block is the FIRST
   gate at the top of device:register — before the fingerprint block, the reconnect
   throttle, any DB writes, or playlist build — so a blocked device's socket is
   refused immediately (auth-error 'Device blocked' + disconnect, zero further work).
   It does NOT rely on null-token (the thing that failed). The row is re-read every
   register, so a DIRECT SQLite edit takes effect on the device's NEXT reconnect with
   NO server restart. Operator statements (dashboard-down, hand-edit):
     block:   UPDATE devices SET blocked = 1 WHERE id = '<device_id>';
     unblock: UPDATE devices SET blocked = 0 WHERE id = '<device_id>';

Tests (port 3987): nulled-token provisioned device is REJECTED (75c2a08a repro);
blocked=1 refused at the first gate (no register/playlist); unblock reconnects;
first-pairing still works; normal valid-token device unaffected. Full suite green
serial AND parallel (213); reconnect-throttle.js + the dbac699 content-ack limiter
untouched.

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

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

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

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

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

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

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

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

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

ScreenTinker 29a8896aa8 fix(#142): global device_status_log retention sweep + STATUS_LOG_RETENTION_DAYS
The per-device insert-time prune (deviceSocket.js) only ever touches a device
that is actively inserting, so it misses two paths: removed/idle devices whose
rows linger forever, and heartbeat.js's offline_timeout insert that bypasses
logDeviceStatus entirely. The reporter's 1.2M-row bloat accumulated UNDER a 7-day
per-device prune for exactly this reason.

- pruneStatusLog() (db/database.js): a GLOBAL time-range sweep across ALL devices,
  modeled on the play_logs prune. Run once on startup (recovers a bloated table
  right after deploy) and on the heartbeat interval (services/heartbeat.js).
- STATUS_LOG_RETENTION_DAYS env, default 3 (lower than the old hardcoded 7d; the
  dashboard only shows a 24h uptime window, so 2-3d is ample for diagnostics).
- Deliberately NO per-device row cap: Step 3's throttle already bounds how fast a
  storming device can generate status rows, so a cap would add sweep complexity
  for little gain (noted for later if needed).
- NO VACUUM / auto_vacuum here (kept off the hot path); space reclaim is left as a
  separate decision (see report).

test: deterministic in-process unit test proves the sweep deletes over-retention
rows across all devices — including a device absent from the devices table and an
offline_timeout row — while keeping recent rows; idempotent on an empty table.

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

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

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

ScreenTinker ed3cf72b82 feat(#142): event-loop lag telemetry (perf_hooks) + bounded storage
Continuously samples event-loop delay via perf_hooks.monitorEventLoopDelay()
(C++-backed histogram; cheap). Each window persists mean/p50/p99/max to a new
event_loop_lag table and recomputes a coarse load band (normal/elevated/critical)
from the window p99. Standalone value: current lag is exposed on /api/status and
band changes are logged, so site lag is diagnosable independent of throttling.

The band feeds the #142 reconnect throttle (next commit) but ships first as its
own subsystem.

- event_loop_lag is bounded from day one: indexed on sampled_at + scheduled prune
  (LAG_TELEMETRY_RETENTION_DAYS, small default) modeled on the play_logs prune.
  Deliberately NOT another unbounded-growth table.
- Band transitions are asymmetric: jump up immediately (tighten fast), release one
  level at a time after N calm samples below a deadband (release slow, no flap).
  Pure nextBand() function, unit-tested deterministically.
- config: LAG_SAMPLE_INTERVAL_MS, LAG_RESOLUTION_MS, LAG_TELEMETRY_RETENTION_DAYS,
  LAG_PRUNE_INTERVAL_MS, LAG_ELEVATED_MS, LAG_CRITICAL_MS, LAG_RELEASE_SAMPLES.
- tests: band-transition unit tests; integration proves sampling persists, stays
  bounded under the prune, and surfaces on /api/status.

ScreenTinker 071d7cc9c3 fix(server): persist per-item mute into the published snapshot (#129)
A mute toggle wrote the draft playlist_items + emitted a live device:mute-changed but only markDraft()'d — it never updated playlists.published_snapshot, the copy the device actually plays. So the device's item.muted stayed 0 and every loop/reload re-applied full volume: dashboard icon red but audio kept playing (Android; web's native <video> loop masked it). emitMuteChanged now surgically patches the matching item's muted (0/1) inside the published_snapshot and re-pushes the playlist, so loops re-apply the correct flag. Surgical patch (not publishPlaylist) so a mute toggle can't prematurely publish other draft edits or flip publish state. Adds a regression test that fails without the patch.

ScreenTinker 0c0a8dd68a fix(ota): surface stuck OTA on dashboard + read APK signer correctly on API 28/29 (#139)
Follow-up to the cache/backoff loop fix (aa23cf0): make a device that can't
self-install visible to operators, and fix the signature-verify bug that kept the
whole #139 fix from engaging on the actual Fire OS target.

Dashboard surface (Phase 2):
- devices gains ota_status / ota_target_version / ota_attempts / ota_updated_at
  via the idempotent ALTER TABLE ADD COLUMN migration (non-destructive,
  default-backfilled, idempotent on re-run).
- The device reports ota_status (OtaThrottle.statusFor -> none | pending |
  manual_update_required) in device_info; the server persists it on register
  (the reconnect backstop). devices d.* already surfaces it to the dashboard.
- Dashboard shows a non-blocking amber badge when manual_update_required
  ("Update available (vX) - install failed N times, manual update required");
  i18n key in en.js (non-en inherits via the en fallback). Server suite +1 test.

Event-driven status (Option B):
- New device:ota-status WS message, emitted on STATE TRANSITIONS only
  (enter-backoff -> manual_update_required, clear -> none), so the badge updates
  promptly without waiting for a reconnect and without per-poll/heartbeat chatter.
  Server handler persists the same fields; an unknown/forged device_id is a safe
  no-op. The register-path persist stays as the reconnect backstop.

Signature-verify fix (the critical piece):
verifyApkSignature read the downloaded APK's signer via
getPackageArchiveInfo(GET_SIGNING_CERTIFICATES).signingInfo, but that field is
null for ARCHIVE files on API 28/29 (populated only from API 30). On Fire OS 8
(Android 9 / API 28) - the actual deployment target - this returned 0 certs from
a correctly-signed APK, so every OTA was refused as "tampered," the cache was
deleted, and the full APK re-downloaded every check cycle. This was the real
cause of the #139 re-download loop, NOT a silent-install failure: the cache and
backoff added in this branch sit behind this verify gate and never engaged on
the target.

Fix: below API 30, read the archive's signer via the legacy GET_SIGNATURES +
.signatures (its v1/JAR cert, which IS populated on 28/29). Keep
GET_SIGNING_CERTIFICATES + signingInfo for API >= 30 and for the installed-app
read (which works on 28+). The archive's signer is still extracted and compared
to the installed app's signer; a mismatch or zero-cert APK is still rejected.
This reads the cert correctly on old APIs - it does not weaken verification.

Verified on emulators:
- API 28: verify now passes for a legit APK (was: 0 certs, refused). Full backoff
  then engages - 8.5MB pulled once, cache-hit on retries, backoff after 3,
  manual_update_required emitted once; clears on successful update.
- API 28 negative: a re-signed (different-key) APK is still refused on cert
  MISMATCH - no hole opened.
- API 30: unchanged path still passes (no regression).
- server suite 173/173, OtaThrottleTest 7/7.

ScreenTinker a36880b147 fix: per-item mute round-trip + multi-zone orphan-zone fallback & warnings
Two independent multi-zone bugs, plus operator-facing warnings, i18n, and
regression tests guarding the data contracts.

Bug 1 — per-item mute was a no-op end to end:
- GET /api/devices/:id dropped the `muted` column from its assignments SELECT,
  so the dashboard toggle never reflected state (the muted=false case in
  particular). Column restored to the device payload.
- Android player now honours the per-item mute flag for YouTube (initial state
  + live via the IFrame JS API).

Bug 2 — items whose zone_id belongs to a different layout were silently dropped:
- Player fallback (web + Android): an orphaned zone_id is recovered into the
  largest zone instead of vanishing, with telemetry.
- server/lib/zone-validate.js is the single source of truth for the orphan rule
  (zone not in the device's active layout); used by the device payload
  (per-item `orphan` flag + `active_layout_zones`) and the device list
  (`orphan_count`).
- Assign-time hardening: a stale zone_id (not in the device's active layout) is
  cleared to null on POST/PUT rather than persisted as a new orphan.
- scripts/find-orphan-zone-items.js: read-only sweep for existing orphans.

Dashboard warnings (operator-facing, never on the live player):
- Per-item badge + reassign affordance, device-list glance, preview banner.
- Graceful degradation: the zone selector falls back to /api/layouts/:id so it
  can't vanish on a stale payload.

i18n: orphan-zone strings added to en/es/fr/de/pt/it (hi falls back by design;
count strings interpolate through tn()).

Tests: server/test/device-zone-contract.test.js adds 5 regression tests for the
data contracts above (muted true/false round-trip, active_layout_zones, orphan
flag + count, orphan-clears-on-reassign, assign-time clearing). 172/172 pass.

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

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

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

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

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

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

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

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

Fix per-item mute (#129): persist, ship to device, and toggle in real time (#130)
* fix(server): persist + ship + real-time per-item mute (#129)

The dashboard mute toggle was a no-op end to end. The active model is playlist_items
(the device payload is its published_snapshot); the legacy `assignments` table the bug
report cited is unused for devices. Three breaks:

- PUT /api/assignments/:id silently dropped `muted` (only read sort_order/duration_sec/
  zone_id). It now accepts muted (coerced 0/1) and ITEM_SELECT returns it, so the toggle
  persists and its on/off state sticks.
- playlist_items had no `muted` column — added (schema + idempotent migration).
- buildSnapshotItems didn't select muted, so it never reached the published_snapshot /
  device payload — now included.

Real-time: on a mute change, emit device:mute-changed { content_id, widget_id, muted } to
every device on that playlist so the player toggles the matching item's volume live,
decoupled from publish (the value is also in the next snapshot, so it persists). Adds a
[mute] log line (the report noted zero mute log entries).

Test: test/mute.test.js — PUT persists + returns muted, it reaches the published
snapshot, and a non-mute update doesn't reset it. Server suite 164/164.

* fix(player): apply per-item mute live on Android + web (#129)

Honor the new per-item mute from the server, both in real time and on reload.

Android:
- WebSocketService: onMuteChanged callback + main-thread device:mute-changed handler.
- MediaPlayerManager.setVideoMuted(): flips the live ExoPlayer volume on the current
  video (YouTube autoplays muted; images/widgets are silent).
- MainActivity: on device:mute-changed, apply immediately if the toggled item is the
  one playing now.
- PlaylistController.sig(): include muted so a published mute change re-renders/persists
  instead of being de-duped.

Web player (server/player/index.html):
- device:mute-changed handler toggles the current <video>; the video mount now also
  honors item.muted so a published mute sticks across reloads.

Tizen intentionally not included: its player mutes ALL video for autoplay, so per-item
unmute isn't achievable there.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

ScreenTinker 400a438fff revert: drop zone-binding, keep whole-playlist grants + size-guidance card (#73)
Investigation found zone placement is a DEVICE property (device.layout_id), not a playlist
property: a normal playlist has no derivable layout (zone_id is NULL unless set in the
device-assignment flow), so a playlist-scoped zone grant can't reach the normal flow. The
right model: placement belongs to the device (same playlist can be full-screen on one screen,
a zone on another); the agency just gets whole-playlist grants + size-guidance.

Removed the zone-grant machinery (security-adjacent dead surface is a liability, not dormant
convenience): api_token_target_zones (schema + a DROP migration for the dev DB where the
short-lived CREATE ran), resolveGrantedZone, grantableZoneIds, buildZoneGrantRows, the
create/PUT zone validation, GET /api/playlists/:id/zones, getPlaylistZones, the settings
zone-picker + its i18n, and the zone-grant bite-test.

KEPT (model-agnostic, good): the reactive per-playlist size-guidance card - GET
/api/agency/playlists/:playlistId/layout (router.param-confined) now reports the zones the
playlist actually feeds (where/what-size content lands), or full-screen when it has no layout.
Whole-playlist grants = today's working model. 147 suite green.

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

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

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

ScreenTinker 289d54f4fa feat(api): zone-grant confinement for agency tokens - FK-anchored (#73)
Placement-as-grant, replacing the inferred auto-place idea. api_token_target_zones is an
ADDITIVE second table (does NOT touch the proven api_token_targets), structurally anchored:
a composite FK to api_token_targets(token_id, playlist_id) makes a zone grant orphan-
impossible and cascade away when the playlist grant is revoked - "narrow" is structural, not
conventional. zone_id FK -> layout_zones cascades on zone/layout delete.

Confinement (lib/agency-targets.resolveGrantedZone, called in the item-add): grants exist ->
the item MUST land in a granted zone (a body zone_id picks among grants, never escapes them);
none -> whole-playlist/full-screen as before. The item-add stamps the granted zone_id.

Bite-tested (6, all proven incl. neutralize->red on the confinement): granted YES; non-
granted/cross-playlist/ambiguous blocked; orphan-grant rejected by the FK; cascade on
playlist-grant revoke, on playlist delete, on zone/layout delete; and foreign_keys=ON
asserted (a cascade that no-ops because FKs are off is the trap). 153 suite green.

ScreenTinker c55ca60b56 feat(api): batched email digest for agency uploads (#73)
Reuses the existing scheduler + sendEmail infra (no new scheduler). The agency endpoint
enqueues one agency_notifications row per item added; a 15-min flush groups unsent rows per
token+playlist+action and sends ONE digest per group to the workspace owner/admins + the
playlist owner (deduped via UNION). Draft -> "added N items, awaiting approval"; published ->
"updated <playlist>".

Two robustness rules, both tested:
- Queue never balloons when SMTP is off: the endpoint skips enqueue when !isConfigured(),
  and the flush drains-and-discards unsent rows as a backstop.
- sent_at is stamped ONLY after a successful send, so a failed send retries next cycle
  instead of silently dropping.

Wired into boot via startAgencyDigest(). 147 suite green.

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

canvas name); thumbnail_data omitted (could render other zones' content).

device exists), and neutralizing the t.token_id filter goes red. 142 suite green.

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

Full bite-suite (test/agency.test.js) GREEN and re-proven to bite on the SHIPPING path:
neutralizing the router.param check makes non-designated->403 go red. Four assertions at
three seams: target (router.param), off-ladder (tokenScopeGate), can't-widen (tokens
JWT-only), issuance cross-workspace (create validation). 139 suite green.

ScreenTinker c8a24d2243 feat(api): agency-token security primitive - off-ladder scope + agencyGate (#73)
The capability/target-restricted token model for the agency portal (#73 option B),
proven before any endpoint sits on it:
- 'agency' scope value is OFF the read/write/full ladder, so the existing tokenScopeGate
  rejects it on every public router by construction (auto-confinement, no new code).
- api_token_targets join table: which playlists an agency token may act on.
- agencyGate: THE single seam - agency-scope-only + (playlist in this token's allowlist
  AND in the bound workspace), one query enforcing target + cross-workspace isolation.
- AGENCY_ROUTERS category in config/api-surface.js (mounted with agencyGate, not
  tokenScopeGate) - declared; router/mount land with the endpoints.

Both bite-tested: spine (agency 403s on tokenScopeGate; read/write still pass) and the
gate (non-designated/cross-workspace/non-agency/JWT -> 403; neutralizing the target check
goes red). NARROW - not the general capability-scope system.

CI / OpenAPI spec lint (push) Waiting to run

CI / Boot smoke + version check (push) Waiting to run
Review caught the encrypted TOTP secret riding in the login/verify response body:
issueSession receives a SELECT * user row and only destructured out password_hash, so
totp_secret_enc (and the internal replay counter totp_last_step) leaked. Encrypted, so
not catastrophic, but it regresses the API work's "secrets never in responses" rule.
Strip both in issueSession (covers /login and /totp/verify); add an assertion that a
verify response carries no totp_secret_enc.

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 3305e79e61 fix(api): consolidate device pairing to /pair, remove vestigial bare endpoint (#90)
POST /api/provision was a second pairing endpoint that paired a device by code but,
unlike POST /api/provision/pair, did NOT assign a workspace, enforce checkDeviceLimit, or
emit device:paired / dashboard:device-added - a silently-diverging duplicate that no
client ever called. It now returns 410 Gone and points callers at /pair, so
/api/provision/pair is the single, fully-protected pairing endpoint. The mount stays in
the JWT-only partition, so a Bearer st_ token still gets 401 (requireAuth) before the 410.

Closes #90

ScreenTinker 538f4a7b03 test(api): close #92 follow-up coverage gaps
The non-security gaps named in the public-API self-review:
- gap-fix: zone_id (playlist items) + layout_id (device PUT) accepted and returned on read,
  INCLUDING the cross-tenant rejection (the is_template OR workspace_id guard - the
  security-relevant one).
- docs serving: /openapi.yaml serves the spec, /docs returns the Redoc page.
- i18n drift-guard: apitoken.* keys have full parity across en/es/fr/de/pt (a key missing
  in one locale fails CI).
- token lifecycle branches: token-create workspace-membership validation and last_used_at
  stamping (integration), plus the must_change_password gate (unit test via the in-memory
  DB injection - cross-process WAL visibility is unreliable for that branch in-process).

119 tests total (was 108), all in the existing node --test job.

ScreenTinker 33eaef826c test(api): fix spec scope drift + guard it in CI; Redoc provenance
Self-review follow-ups, kept as a separate commit so the review trail is honest.

- Spec drift: POST /widgets/preview was documented scope 'read' but the method-based
  tokenScopeGate enforces 'write' for any POST, so a read-token integrator following the
  published docs would hit a surprise 403. The code is right; fix the SPEC to match it.
- Guard it forever: test/openapi-contract.test.js cross-checks every spec operation's
  x-required-scope against the enforcement rule, and that every documented path is a
  public (token-reachable) router - both derived from the same config/api-surface.js.
  Adds js-yaml (devDep) to parse the spec. Spec/enforcement drift now fails CI.
- Vendored Redoc: add frontend/vendor/README.md (library, version 2.3.9, source, update
  steps) and drop the dangling //# sourceMappingURL line so /docs doesn't 404 in devtools.

Remaining (non-security) test-coverage gaps tracked in #92.

ScreenTinker 2ad9f54b8e test(api): token partition + threat-model + device WS coverage
A dedicated public-API suite (boots the real server as a subprocess) so CI green proves
the token layer, not just the pre-existing tests:

- Partition firewall, derived from the SAME config/api-surface.js server.js mounts from:
  every JWT-only router 401s a token; a public-surface snapshot fails if any router is
  added to the token door; known-privileged routers asserted JWT-only.
- Threat model: role-strip gates, workspace-binding both directions (token ignores
  X-Workspace-Id, JWT honors it), the scope ladder, the render bypass, token lifecycle,
  and JWT no-regression.
- Device WS round-trip via socket.io-client (added as a devDep): valid device_token
  registers + receives its playlist; wrong token rejected.

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 52b10408be chore(version): single-source VERSION, env-configurable data paths, bump tooling
- server/version.js: shared version helper that reads the root VERSION file once
  (fallback 0.0.0). Replaces the stale hardcoded 1.2.0 / 1.5.1 / 1.0.0 fallbacks
  in /api/version, /api/update/check, and /api/status.
- config.js: DATA_DIR / DB_PATH / UPLOADS_DIR / CERTS_DIR env overrides for the
  db, uploads, and certs/jwt-secret locations. Unset resolves to exactly the
  legacy in-repo paths, so existing installs (including production) are
  byte-for-byte unchanged. Guarded by test/config-paths.test.js.
- package.json: rename remote-display-server -> screentinker (+ lockfile name).
- scripts/bump-version.sh: one-shot bump across VERSION, package.json (+lock),
  android (versionName and versionCode + 1), and the tizen widget version; makes
  one commit plus an annotated tag; prints the push command, never pushes.
- .gitignore: global *.db / *.db-wal / *.db-shm / *.db.* so no database file
  (including .db.devbak backups, at any path) can be committed.

ScreenTinker 734795f20b fix(ai): de-overlap generated text + layer shapes behind text (#41)
Models sometimes stacked text lines at the same y (unreadable) and emitted accent
shapes after text, so a band could hide the words.

- deoverlapTexts: push a line down only when it also overlaps horizontally
  (leaves side-by-side text alone), with conservative line-height clearance so
  real rendering doesn't re-overlap; shift the stack up if it ran past the bottom.
- Order shapes before text in the output so accent bands always render behind the
  words.

Verified: 0 text-on-text overlaps across multiple prompts (Playwright DOM check);
unit test asserts overlapping lines get separated + shapes precede text. 63/63.
2026-06-09 12:57:41 -05:00
ScreenTinker 4cc8ccb67e fix(ai): keep generated designs inside the canvas (#41)
Text could run off the edge (long/large headlines, nowrap) and shapes placed at
the far edge (e.g. a bottom band at y=100) spilled over.

- Server-side fit pass on every generated element: shrink text fontSize so it
  fits the canvas width (chars*fontSize*0.075, tuned for bold/uppercase
  headlines) and height (incl. line-height), then nudge x/y within 4% margins;
  clamp shapes so x+width<=100 and y+height<=100. Deterministic - doesn't rely on
  the model getting layout right.
- Designer preview: vw -> cqw (+ container-type on the canvas) so text scales to
  the canvas, not the browser window. The preview was overstating size vs what
  actually publishes; now it matches. Published widget keeps vw (scales on the
  player).

Verified: Playwright DOM check shows zero elements overflowing the canvas after
generation; unit test asserts long text is shrunk + repositioned in-bounds. 62/62.

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.
2026-06-09 09:22:21 -05:00
ScreenTinker ae595a208d feat(admin): Create Organization for platform admins (#35)
MSPs onboarding customers as separate orgs had no way to create one with
AUTO_CREATE_ORG_ON_SIGNUP=false (the only path was signup auto-org). Add a
platform-admin 'Create organization' action.

POST /api/admin/orgs (requirePlatformAdmin) creates the org + its first 'Default'
workspace. organizations.owner_user_id is NOT NULL, so an org can't be ownerless;
the creating admin becomes org_owner + workspace_admin (mirrors the signup
bootstrap in routes/auth.js) - which also surfaces the org in their switcher.
Customer users are then added via the existing Add User / manage-memberships flow.

UI: 'Create organization' button + single-field modal in the Admin area (gated).
Tests: create (201 + memberships + audit), empty-name 400, non-admin/operator 403.

ScreenTinker 401c4b00b5 fix(security): sanitize public widget render to close stored XSS
The public, CSP-exempt widget render (GET /api/widgets/:id/render) inlined
config values straight into <style>/CSS and (for the text widget) raw into the
same-origin document. A workspace editor could store `}</style><script>...` in a
color/background/size field (bypassing the UI pickers via the API) → stored XSS
executing in the app origin for anyone who opens the render URL (JWT theft).

- safeCss(): allow colors/gradients but reject CSS breakout / url() / @import /
  expression / javascript:. Applied to background/color across clock, weather,
  rss, social renders.
- safeNumber(): coerce font_size / scroll_speed / max_items to a finite number
  so they can't smuggle markup.
- Text widget keeps its intentional raw HTML/CSS feature, but it now renders
  inside an <iframe sandbox="allow-scripts"> (NO allow-same-origin) - scripts run
  in a null origin that can't reach the dashboard's localStorage/JWT.

Tests: test/widget-render-xss.test.js (breakout rejected, numbers coerced, text
isolated, legit colors/gradients preserved). Full suite green.

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.

Closes #15.

ScreenTinker 2872b883c7 feat(admin): manage a user's workspace memberships (multi + per-workspace role)
The Workspace column on the platform Users page could only move a 0/1-workspace
user and showed a dead "N workspaces" label for multi-membership users. Replace
it with a "Manage workspaces" modal that handles the full picture.

Backend (routes/admin.js, requirePlatformAdmin):
- GET    /api/admin/users/:id/workspaces            list memberships (+org/ws names, role)
- POST   /api/admin/users/:id/workspaces            add to a workspace (upsert role)
- PUT    /api/admin/users/:id/workspaces/:wsId      change role in a workspace
- DELETE /api/admin/users/:id/workspaces/:wsId      remove (last one allowed -> unassigned)
Roles validated against WORKSPACE_ROLES; each mutation writes an audit row.

Frontend:
- Workspace cell is now a summary (Unassigned / <name> / N workspaces /
  "Platform (all)" for staff) + a Manage button.
- New admin-user-workspaces-modal: lists every membership with an inline role
  dropdown + Remove, plus a type-to-filter "Add to workspace" picker (org-grouped,
  excludes current memberships) with a role select. Staff get a note that they
  already have platform-wide access. Refreshes the table on close if changed.
- Removed the old single-select inline move control (superseded by the modal).

Tests: 6 added (add to multiple workspaces, per-workspace role change, upsert,
remove incl. last->unassigned, validation 400/404, non-platform-admin 403).
Full suite 33/33. Verified headless: Manage opens, lists memberships, filtered
picker, add/role-change/remove round-trips persist (throwaway user, cleaned up).
2026-06-08 16:24:52 -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.
2026-06-08 16:01:52 -05:00
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 7615eabdd5 feat(admin): Workspace column + inline move/assign on the Users page
Adds a "Workspace" column (after Plan) to the platform Users admin table so a
platform_admin can see and reassign a user's workspace inline, alongside the
Role/Plan dropdowns. Single-workspace move/assign model.

Backend:
- GET /api/auth/users (platform branch): one aggregate query adds
  workspace_count and, for exactly-one membership, the workspace id/name + org
  name (no N+1).
- PUT /api/admin/users/:id/workspace (requirePlatformAdmin - operator excluded):
  move (1 membership) or assign (0) into the chosen workspace, default role
  workspace_viewer, in a transaction; no-op if already there; REFUSES (400) a
  user with >1 membership (manage in the members view). logActivity
  admin_set_user_workspace.

Frontend (admin.js):
- Editable <select> only for a 'user' with 0/1 membership; multi-membership ->
  read-only "N workspaces", platform staff -> read-only "Platform (all)".
- Options grouped by org via <optgroup>, built ONCE from /me's
  accessible_workspaces (same source as the Add User picker) and reused per row.
- Picking "Unassigned" or the same workspace is a no-op so a stray pick can't
  strip a membership. Success -> toast + refresh. EN i18n only.

Tests: 4 added (single-membership move 200 + changed, zero-membership assign
200, multi-membership 400 refused, non-platform-admin/operator 403). npm test
16/16. Verified headless: column renders, selected value correct, "Platform
(all)" for staff, and a dropdown move persisted (throwaway user, cleaned up).

ScreenTinker 5502a3eaa8 fix(roles): make platform_operator assignable + add deny/assign regression tests
The bug: #13 added 'platform_operator' to the frontend role dropdown
(PLATFORM_ROLE_OPTIONS) but #14's PUT /api/auth/users/:id/role whitelist
(ASSIGNABLE_PLATFORM_ROLES) only listed ['user','platform_admin'], so
selecting "Platform operator" returned 400 "Invalid role" - the role was
unassignable via the UI.

Fix: add 'platform_operator' to ASSIGNABLE_PLATFORM_ROLES. One line; the
self-demote guard is intentionally left untouched (a platform_admin still
cannot self-assign the non-owner operator role and lock themselves out).

Tests (node:test, isolated in-memory DB injection - no DB_PATH change):
- admin-users.test.js: platform_admin can PUT role=platform_operator on a
  target user -> 200 and the row persists as platform_operator (regression
  guard for the whitelist gap).
- operator-permissions.test.js (new): verify-then-test of the highest-blast
  -radius deny. Operator CAN update/delete a workspace-scoped content row
  (cross-org write works) but is denied (403) updating or deleting a shared
  (workspace_id IS NULL) row - proving the separate PLATFORM_ROLES gate in
  content.js's checkContentWrite still holds after canWrite was broadened to
  isPlatformStaff.

Verified read-only (no leak): the other shared-asset write sites keep their
PLATFORM_ROLES gate that excludes operator - kiosk.js:57, widgets.js:110,
folders.js:31, layouts.js:59/117/133.

cd server && npm test -> 12 pass / 0 fail.

ScreenTinker 7674f6dc9f test(admin): node:test coverage for Add User + role gating
Adds server/test/admin-users.test.js and a `npm test` (node --test) script.
No DB_PATH override: the suite mounts the real routers against an isolated
in-memory better-sqlite3 instance injected into the require cache, seeded by
the test itself. Node v20 built-ins only (node:test, node:assert, fetch).

Covers: Add User success (response omits password/hash, hash stored not
plaintext, membership written, hosted lifecycle sentinels stamped, audit row
without the password), duplicate-email 409 (no overwrite), non-admin 403,
platform_operator denied (403), org_admin scoped to their own org only,
input validation, and the must_change_password lifecycle (set on create,
surfaced on login, cleared on PUT /api/auth/me).
