A layout with several network-backed widgets (photos, weather,
calendar) paid their fetch latency serially in one /frame/* request,
which could exceed the firmware's fixed HTTP timeout and show a false
"server failed" status screen even though the server was still
working -- most visibly on the hold-triggered "cycle layouts" action,
which swaps in a whole new, cold-started widget set. Each widget now
renders on its own DB session in a thread pool (a plain Session isn't
thread-safe to share, but the per-frame threading.Lock in
frame_locked/widget_locked already made this kind of concurrency safe
by design -- see app/db.py); regions are still collected in
sort_order so overlapping widgets paint in the same z-order as before.
The share QR's URL carried no auth params at all, so it silently fell
back through require_device's legacy-token resolution to whichever
frame happened to still be flagged legacy -- working only by accident
for a single frame, sharing the wrong frame's photos for any other, and
going fully dead once that frame's legacy flag was cleared.
Move the endpoint to manage.py, keyed on the frame's own manage_token
(same pattern /m/<manage_token> already uses) instead of device auth.
Since the server now resolves assets itself instead of trusting a
caller-supplied asset_id, it naturally generalizes to gather every
photo widget's current photo into one Immich share link, not just one
"primary" widget's.
device.py's mode-keyed dispatch is replaced by a real compositor:
load a frame's widgets, compute pixel rects via app/grid.py, render
each through its widget module, and composite with render_panel.
Physical NEXT/BACK buttons now execute each frame's assigned
FrameButtonAction rows instead of one hardcoded per-mode action.
api_frames.py, manage.py, and common.py's build_manage_content are
repointed to read/write the frame's widget config rows instead of
the old Frame columns, and every settings page (Photos/Calendar/
Whiteboard tabs) now pre-fills its form from the same widget config
the write endpoints actually save to -- previously the read and
write sides would have silently diverged. The old mode selector and
photo-inlay checkbox are removed along with their now-inert wiring;
arbitrary widget placement subsumes what the fixed inlay split did.
Ships together with Phase 1 (per-type render/action modules) since
splitting the read/write cutover across deploys would have left
settings changes with no visible effect.
