After uploading, content thumbnails were blank until the item was added to a
playlist/widget. The public /api/content/:id/thumbnail (and /file) endpoints are
reference-gated (an anonymous player with a UUID must not pull arbitrary tenants'
media), and a plain <img> can't send a Bearer token - so a just-uploaded item 403'd.
- Backend: add an authenticated bypass - a logged-in user who can access the
content's workspace (verified from the Bearer token) may view its file/thumbnail
even when unreferenced. Anonymous players still hit the reference gate.
- Frontend: the content library lazy-fetches thumbnails/previews WITH the token
and swaps in an object URL (IntersectionObserver keeps it under the rate limit;
the URL is revoked after load).
Verified: unreferenced thumbnail now 200 with a bearer token, still 403 anonymous.
The upload input already has 'multiple' and the click handler shares handleFiles()
with drag-drop, so picking multiple files (shift/ctrl-click) already works - it just
wasn't discoverable ('click to upload' read as single-file). Reword to 'click to
select one or more'.
Saving a layout grew its zone count on every server restart. Root cause: the
editor saved zones with a per-zone delete-then-POST loop, and POST /zones minted
a NEW uuid for every zone - so each save replaced the seeded ids (z-sh-1, ...)
with fresh uuids. schema.sql re-seeds template zones via INSERT OR IGNORE on every
boot, so the next restart re-added the now-missing canonical zone alongside the
renamed copy -> a 2-zone template became 4, 6, ... (worse for self-hosters who
rebuild often).
Fix:
- PUT /api/layouts/:id now accepts a zones[] and replaces them atomically in one
transaction, REUSING each zone's id when supplied. The editor sends the full
set in a single call, so the layout ends up with exactly those zones and ids
stay stable (also fixes fit_mode not persisting, and stops device->zone
assignments being orphaned by id churn).
- One-time dedupe migration removes positional-duplicate template zones, keeping
the canonical 'z-...' seeded id so the re-seed stays an idempotent no-op.
Verified: 2 atomic saves keep count + ids stable with fit updated; dedupe restores
a polluted 4-zone split template to its 2 canonical zones. Suite 56/56.
The boot summary counted any non-throwing statement, so UPDATE/index migrations
(which always succeed) made a healthy DB report 'applied N new column migration(s)'
every boot. Count only a successful ALTER ... ADD COLUMN (genuinely new), so the
line appears only when a column was actually added.
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.
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.
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.
Multi-zone videos/images were cropped: every template zone inherited fit_mode
'cover' (fill+crop) and the layout editor had no control to change it, so a
landscape video in a tall split zone showed only a center strip. The player
already honors fit_mode (web object-fit, Android scaleType) - the gap was the UI
and the default. Add a per-zone Fit selector (Contain/Cover/Stretch) to the layout
editor, and make 'contain' (show the whole frame) the default for new zones, the
schema column, and the save fallbacks. Existing built-in templates are migrated
separately.
Follow-up to the layout cache. On a cold start with a cached playlist but no cached
layout yet (first run after shipping, or cleared cache), the player still rendered
fullscreen and flashed before the payload arrived. Now gate the optimistic cached
render on the layout being KNOWN (cache key present — null=fullscreen vs object=
zoned, both fine); if unknown, wait ~1s for the payload to drive the first render.
Eliminates the fullscreen flash on the very first pass too.
The player cached only the playlist, not the layout. On cold start it restored the
playlist and rendered immediately with layout=null -> fullscreen, then re-rendered
into zones once the server payload arrived (the 'fullscreen first, then split'
flash). Cache the layout alongside the playlist and restore it before the first
render; cleared on reset.
A widget (e.g. directory board) assigned to a 'content' zone rendered as a black
zone: showZoneItem gated the widget branch on zone.zone_type==='widget', so the
widget was skipped and (mime_type null) nothing else matched either. Key off the
assignment's widget_id instead - matching the Android ZoneManager, which is why
the same layout worked on the APK but not the web player.
The render had no Cache-Control. A copy cached before the X-Frame-Options fix keeps
showing blank, and widget data (clock/weather/rss/directory) is dynamic anyway, so
mark the render no-store. Pairs with the X-Frame-Options removal.
The web player embeds widget/kiosk renders in a sandboxed (allow-scripts, no
allow-same-origin) iframe = a null origin. The global helmet X-Frame-Options:
SAMEORIGIN refuses that (null != same-origin), so every widget rendered blank in
the web player (video worked since it isn't an iframe). Drop X-Frame-Options on
just the /render endpoints - the sandbox, not X-Frame-Options, is what isolates
the widget from the dashboard (it still can't read the JWT). Dashboard keeps its
clickjacking protection. Verified: directory board now renders in a sandboxed
iframe with no refusal.
Mirror of the Android fix. The web player showed only the FIRST assignment per
zone (playlist.find) and an image zone set the GLOBAL advanceTimer->nextItem, so
the whole layout re-rendered on one global tick instead of each zone cycling its
own content. Now each zone groups its assignments (by zone_id, sorted), renders
the first, and advances on its OWN timer (images/widgets/youtube: duration;
videos: on end; single-item zones loop). Cleared in teardown. Also render zones
before the single-item 'renderable?' bail so an empty current item can't blank
the screen.
sw-admin.js (scope '/') intercepted every non-API GET with clone+cache+respond.
Video requests are Range requests -> 206 Partial Content, which can't be cached;
cache.put threw and the handler errored ('ServiceWorker encountered an unexpected
error'), so .mp4s never loaded on any page this SW controls - including the web
player at /player, which then thrashed between items.
Now bypass (network-only) non-GET, Range requests, and /uploads//player/api/
socket.io; only cache same-origin 200s. CACHE bumped to v4 so clients pick up the
new SW + drop the stale bucket.
- YouTube: load the embed via loadDataWithBaseURL with a youtube.com base URL so
the iframe has a valid origin/referer (a bare loadUrl of /embed/ID gives
'player misconfigured, Error 153'). Applies to zone + fullscreen YouTube.
- Web frames: shared WebViewSupport.configure() enables mixed-content (self-hosted
http LAN servers) and pipes WebView load/HTTP/JS-console errors to DebugLog, so a
failing web frame surfaces the real error in the live panel instead of a black
broken-page view.
After stopping the fullscreen controller in multi-zone, the only switch logs went
away - each zone now logs every item it renders (initial + each rotation) so the
live debug panel shows each zone advancing on its own interval.
From Chris's live debug logs on the L-Bar layout:
- ZoneManager only rendered the FIRST assignment per zone -> the Main zone (3
images) never rotated ('says it's switching but it's not'). Now each zone
cycles its own assignments: images/widgets on a duration timer, videos on
end (single-item zones still loop).
- The fullscreen PlaylistController kept running BEHIND the zones (playItem every
10s, would leak audio for a zone video) because startIfNeeded() ran after every
playlist update. Now only start it when not in multi-zone (zoneManager.hasZones).
- renderAssignments still called container.removeAllViews() (the same static-view
nuke the cleanup() fix addressed) -> now removes only its own zone views.
- Server (deviceSocket buildPlaylistPayload): when a device's layout has <2 zones
(single or none), strip leftover zone_id from assignments. After switching a
device from multi-zone back to fullscreen, content was stuck bound to a gone
left/right zone_id and never played; nulling it lets both players fall back to
the default fullscreen renderer.
- Web player: render multi-zone zones BEFORE the single-item 'renderable?' bail,
so an empty/placeholder current rotation item can't blank the whole screen.
On a short viewport (e.g. 1366x768) the sidebar nav was taller than the screen
with no scroll, so items below the fold (Settings) were unreachable. Add
overflow-y:auto + min-height:0 to .nav-links (the min-height:0 lets the flex
child shrink and scroll instead of overflowing).
The black-screen on fullscreen widgets (and any single-zone playback after using
a multi-zone layout) was here: cleanup() called container.removeAllViews(), but
`container` is the activity root that also holds the static playerView/imageView/
youtubeWebView/statusOverlay. Removing them detached the WebView that the
fullscreen widget path reuses -> black. Remove only the zone views we added.
Widgets worked in multi-zone layouts (ZoneManager renders them in a WebView) but
were broken in "default fullscreen" (no layout) and the fullscreen template (a
single-zone layout) - both take the single-zone PlaylistController path, which:
1) called getString("content_id"), throwing on a widget assignment (no
content_id) - in both the playlist builder AND the pre-download loop, which
could break the whole fullscreen playlist; and
2) had no widget render case in playItem (so a widget never displayed).
Fix:
- PlaylistItem gains widgetId/widgetType + isWidget; the builder reads them and
tolerates a missing content_id.
- playItem renders a widget fullscreen via MediaPlayerManager.showWidget() (loads
/api/widgets/:id/render in the full-screen WebView, mirroring ZoneManager).
- Widgets auto-advance on their duration like images.
- Pre-download loop skips widget assignments (no file to fetch).
Compile-checked; signed APK builds. Needs on-device check: a widget plays in
default-fullscreen and the fullscreen template, and mixed widget+media playlists
advance correctly.

- The code's bottom was still clipped: the autosize TextView used wrap_content
height, which clips glyph bottoms. Give it a fixed 96dp box (autosize 24-64sp,
gravity center) so the text is centered inside a bounded box and never clipped.
- The "Enter this code…" line appeared twice (static label + statusText). Clear
statusText when paired so it shows only once, with the code.
Follow-up to the provisioning layout fix - on a Pixel the code's bottom half was
cut off. Tightened the screen so the whole block fits:
- "RemoteDisplay" title 36sp -> 22sp, smaller subtitle + margins.
- Anchor content to the top (gravity center_horizontal|top) so the code sits
high instead of being pushed below the fold by vertical centering.
- Pairing code autosize cap 96sp -> 56sp + vertical padding, so tall digits
aren't clipped and the block stays on screen on short/landscape phones.

Reported on a Pixel 10: the pairing code wasn't visible. The provisioning screen
was a non-scrolling vertical stack, and when the pairing section appeared below
the server-URL + Connect controls, the fixed 64sp code got pushed off-screen on
short/landscape phones (and could clip horizontally on narrow widths).
- Wrap the screen in a ScrollView (fillViewport) so content is always reachable.
- pairingCodeText now auto-sizes (autoSizeTextType=uniform, 24-96sp, single line,
match_parent width) so it fills the width and never clips - phones, TVs, sticks.
- Hide the server-URL section + Connect button once paired so the code gets the
full screen.
Compile-checked + signed APK builds. Needs on-device confirmation (Pixel 10 /
onn stick) that the code is now visible.

The updater fetched download_url from the server JSON and installed it via
PackageInstaller with NO verification, over cleartext (usesCleartextTraffic,
no pinning). A network MITM or compromised server could return a malicious APK
and have it silently installed (REQUEST_INSTALL_PACKAGES) → full device RCE.
Fix: before install, verify the downloaded APK (a) is our own package and
(b) shares a current signing certificate with the installed app
(GET_SIGNING_CERTIFICATES on P+, GET_SIGNATURES below). An attacker can't forge
our signing key, so this holds even over an untrusted/cleartext transport.
Fail-closed on any parse/verify error; the APK is deleted on mismatch. Gates
both the session-install and intent-fallback paths.
Also set android:allowBackup="false" so adb backup can't exfiltrate the
device token / config.
Compile-checked + signed debug APK builds. NOT verified on-device - needs a
real update cycle on a device (valid update installs; a wrong-signed APK is
rejected) before merge.

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.
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.
