A QA sweep found unescaped interpolations outside the SSO work. Auditing them properly
turned up 34 genuine HTML sinks; 23 carry data a user, a device or an identity provider
controls, and those are escaped here.
The ones that mattered:
- app.js renders `user.name` in the shell on EVERY page, and an identity provider's
`name` claim is stored verbatim, so an IdP could script the whole dashboard
- designer element `label`/`location` and widget `location`/`query` land inside
value="" attributes, where a single quote breaks out
- content `folder` lands in a data-folder="" attribute
- device `name` is set by the operator OR reported by the panel itself
- workspace-members renders a SERVER error string through t(), which interpolates raw
⚠️ My first attempt was a codemod over everything my scanner flagged, and it was wrong.
It wrapped `progressText.textContent`, `block.title` and `confirm(...)` — none of which
are HTML, so escaping there shows users literal `<`. Worse, it wrapped
`title: ev.title ? ... : null`, an API PAYLOAD, which would have written escaped markup
into the database. I reverted the whole thing and narrowed to interpolations that are
genuinely inside an HTML template, then read all 34 and chose 23.
Skipped deliberately: static app strings, i18n output, ternaries yielding `selected`,
`window.location.origin`, and sites already escaped.
Verified in Chrome, not by inspection: the payload was seeded into user.name,
device.name, content.filename/folder, widget.name/config and video_wall.name (the first
attempt's seeds silently failed on column names — the API responses are checked now),
then eleven views were loaded. Zero executions, zero live img tags — AND the payload is
visible as inert text in 6/6 views, which is what proves the views rendered it rather
than the test proving nothing.
1609 tests; every frontend module parses as an ES module.

Each of these views carries its own copy of a fetch helper ending in `.then(r => r.json())`. A 403,
404 or 500 body resolves as an ordinary value, so the surrounding try/catch is unreachable and every
handler treats the failure as success. The shared client in api.js has always thrown on !res.ok;
these local copies never did.
Two concrete consequences, both of which tell the operator something untrue:
- The layout editor renders a Delete button on built-in templates for everyone. The server returns
403. The handler shows "Layout deleted" and re-renders the list with the template still sitting
there.
- A rejected platform-role change in Admin shows "Role updated", and the revert that would put the
dropdown back lives only in the dead catch — so the UI keeps displaying a value the server
refused. The same control in Settings uses the throwing client, so the two pages disagree about
whether the change happened.
All eight now match the shared contract: reject on !ok with the server's own message, and treat 401
as session expiry the way api.js does.
This makes previously-silent failures visible, which is the point — some of them will surface
refusals that were always happening. The layout template Delete button, for instance, is now
honestly reported as refused rather than falsely confirmed; whether that button should be shown at
all is a separate question.

* feat(widgets): bulk import for the directory board (JSON / CSV / TSV / text)
Adds an "Import from JSON / CSV" button to the directory-board editor. Paste JSON
(the { company, tenantsByFloor, advertisements, backgroundImages } shape plus
categories[]/floors[]/flat-array/bare-floor-map variants), a CSV/TSV/pipe/semicolon
table (with or without a header — vacant/yes/1 => available, quoted fields), or a
sectioned "room name" text list, and it auto-fills title, footer, floors->categories,
rooms/names/details/availability, and background-image URLs. "Replace / append" toggle.
Tolerant key matching (room/suite/unit/id, name/tenant/company, details/subtitle, …);
warns on things it can't use (bare-filename background images, headerless columns).
parseDirectoryImport is pure and was unit-tested in node across every format.

* 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.

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

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

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

#182 shipped hydrateAuthImages() loading every thumbnail immediately, which
regressed the content-library grid from lazy to eager (a fetch per thumbnail on
render) and left the IntersectionObserver as dead code.
Restore lazy-by-default (observe-only) so large grids only fetch thumbnails as
they scroll into view, and add an { eager: true } opt-in for the transient
pickers where every item is on screen and immediate load reads better: the
device assign-content modal, the playlist add-item modal, and the widget
content picker. Grids and inline lists (content library, playlist items, device
playlist tab, directory logo/background) use the lazy default.
Behavior for those pickers is unchanged; only the large grids revert to the
lazy loading they had before #182.

* fix(dashboard): use data-auth-src for thumbnail images in modals and views
Plain <img src> tags can't send the Bearer token, causing 403 on
/api/content/:id/thumbnail. Extracted loadAuthImage/hydrateAuthImages
from content-library.js into utils.js and applied the data-auth-src
pattern to playlists, device-detail, and widgets views.
Closes thumbnail rendering in:
- Playlist items list and add-item modal
- Device assignment list and assign-content modal
- Widget content picker, logo, and background images
* fix(dashboard): add requestAnimationFrame fallback for auth image hydration
The IntersectionObserver callback fires asynchronously and may miss
images on first render when the DOM layout isn't settled yet. Add a
rAF fallback that manually loads any still-unloaded images visible
within the viewport (same 300px margin as the observer).
* fix(dashboard): load visible auth images synchronously, not via observer
getBoundingClientRect() forces layout synchronously so visible images
load immediately. IntersectionObserver is now only used for lazy-
loading off-screen images. This eliminates the async timing gap on
first render where neither the observer callback nor rAF would fire.
* fix(dashboard): load all auth images immediately, skip visibility check
Simplifies hydrateAuthImages to load every img[data-auth-src] directly.
loadAuthImage deletes the attribute so observer double-fire is safe.
This eliminates any possible IntersectionObserver/BoundingClientRect
timing issues on first render.
* debug: add console logs to trace auth image hydration flow
* fix(dashboard): hydrate auth images in device detail initial load
loadDevice() renders the playlist tab with data-auth-src images
but never called hydrateAuthImages. Only the playlist-switch path
(line 1022) had the hydrate call. Added hydrateAuthImages to the
initial contentEl.innerHTML render so thumbnails load on first view.
* chore: remove debug logs, final clean version
* fix(preview): replace srcdoc with server-side preview sessions to bypass CSP
Widget previews (clock, weather, etc.) were rendered via iframe.srcdoc,
which inherits the dashboard CSP script-src 'self'. This blocked the inline
scripts widgets need (setInterval for clock, fetch for weather), causing
previews to show blank/static content.
Replace srcdoc with ephemeral server-side preview sessions:
- POST /api/widgets/preview-session — stores rendered HTML (Map, 5min TTL)
- GET /api/widgets/preview-session/:id — serves the HTML via iframe src,
bypassing CSP like the device render endpoint already does
The old /api/widgets/preview endpoint is unchanged for backward compat.
* fix(preview): add rate limiter for /preview-session route

Replaces the broken/fragmented preview with a single surface that renders a
DRAFT playlist exactly as a device does, by reusing the player's renderer in a
same-origin iframe. Fixes "not all items load" (one renderer, full type union)
and inherits the player's YouTube correctness (YT.Player handshake).
Server:
- deviceSocket: extract assemblePayload() (zone-reset + canonical shape) from
buildPlaylistPayload so the device path and preview can't drift. Pure refactor
(all 149 tests green).
- playlists: GET /:id/preview-payload (requirePlaylistRead, workspace-scoped).
Draft-aware via buildSnapshotItems (live items, not published_snapshot);
derivePreviewLayout() resolves layout from the playlist's own zone-bound items
(0 zoned -> fullscreen; 1 -> use it; >1 -> dominant + ambiguous flag, never
crashes). orientation validated/passthrough; wall_config/timezone null.
Player (renderer UNTOUCHED):
- ?preview=1&playlist=ID boot branch: fetch preview-payload (same-origin Bearer
token) and call handlePlaylistUpdate(). Gated before the pairing/socket path
so the unpaired auto-connect never fires. All socket emits already guarded.
- Webpage widgets: always-visible honest note (no auto-detection — an XFO
refusal is provably indistinguishable client-side from a working embed).
Dashboard:
- playlists: Preview button + player-iframe modal with landscape/portrait toggle.
- widgets: same honest note on the existing widget preview modal (the surface the
bug was reported on).
- i18n x6 (en/es/fr/de/it/pt) + player i18n x5.
Validated end-to-end (headless Chrome + CDP): preview boots, webpage note
renders, 3-zone layout derives+renders, shape parity with device snapshot proven
on real data, auth gate returns 401. The world-readable /uploads finding is
tracked separately as #107 (not a #104 concern — same path the device uses).

Addresses the primary finding from the May 27 security report (issue #8):
the admin widget preview modal (frontend/js/views/widgets.js) and the web
player widget renderer (server/player/index.html, 2 sites) loaded
user-authored widget HTML into unsandboxed iframes. Same-origin scripts
in the widget content could access window.parent.localStorage and
exfiltrate the JWT.
sandbox="allow-scripts" without allow-same-origin sandboxes the widget
into a unique origin: inline scripts (clock, RSS, weather widgets)
continue to work, but parent-origin access and same-origin requests are
blocked. Verified via Playwright probe against all 6 widget types in the
dev DB (clock, rss, social, text, weather, webpage): each renders
correctly under the new sandbox and contentDocument access from the
parent is blocked (opaque-origin enforcement working). Admin preview
unchanged in appearance; player display unchanged.
Webpage widget (server/routes/widgets.js) sandbox tightening (drop
allow-same-origin) is a separate forthcoming commit - needs test against
real embed URLs since some sites rely on same-origin behavior. The
sandbox-attribute intersection rule means today's outer-iframe sandbox
will cascade and strip allow-same-origin from the webpage widget's inner
iframe too; accepted as a narrow cosmetic regression (cookies/localStorage
stripped for embedded sites) until the deliberate inner-iframe handling
ships.
SECURITY.md added with reporting process (GitHub Security Advisories
primary, support@bytetinker.net fallback) and scope.

Inline editor with:
- Collapsible categories, reorder up/down, delete
- Entries with identifier, name, subtitle, available toggle
- Add/remove with auto-focus on new row
- Empty state prompts first category
- Theme, scroll speed, column count selectors
- Reusable content picker (single/multi-select) against user's image library
- Logo picker + background image picker (multi) via that picker
- Preview button posts unsaved config to /widgets/preview and shows the
returned HTML in a modal iframe (srcdoc + injected <base> so relative
content URLs resolve against our origin)
- Delete confirms with widget name
Also escapes w.name / typeMeta.name / w.id in the widget grid to prevent
stored XSS against admins viewing other users' widgets.
