Follow-up to 73f41c3 (server-side zone_id wiring). With this commit
the zone feature is verified working end-to-end: dashboard zone
picker renders correctly, zone_id saves and persists, the per-row
zone dropdown reflects the saved zone after reload, and a live
player run with computed-style inspection confirmed zone divs and
video elements size correctly within their geometry.
Frontend (device-detail.js, en.js):
- Add-content modal: zone picker slot now renders in all four states
(has_zones / no_layout / fetch_failed / empty_layout) instead of
silently vanishing when zones.length === 0. Informational rows
match form-group styling and tell the user which control to use
next. Closes the gate-4 symptom where 38-of-42 devices (no layout
assigned) silently dropped zone_id on every assignment.
- Both /api/layouts/:id fetches (add modal, edit-path) now have
!res.ok throw guards and surface failures via console.warn instead
of swallowing them. The add modal additionally exposes the failure
state to the user via the fetch_failed info row.
- Edit-path zone dropdown: replaced brittle DOM-scraping (reading
the i18n label text and matching z.id.slice(0,8) against rendered
meta HTML) with a data-current-zone-id attribute stashed at row
render from a.zone_id. Removes the i18n-format coupling and gives
exact UUID match.
- 3 new i18n keys in en.js (other locales fall back).
Server (devices.js):
- The GET /api/devices/:id assignments query had its own ad-hoc
SELECT projection that was missed during the 73f41c3 site survey.
Without pi.zone_id in this projection, loadDevice() got assignments
without zone_id and the edit-path dropdown displayed "No zone"
after every save+reload even though the DB had the correct value.
One-line fix: add pi.zone_id, mirroring the ITEM_SELECT change in
routes/assignments.js. Listed as the 8th site that 73f41c3's
original survey missed; this commit closes it.
Verification:
- JS parse + en.js ESM load + server module load all clean.
- Live SQL probe: GET /api/devices/:id projection now returns zone_id
for the test rows (id=31 zone_id=z-sh-1, id=54 zone_id=z-sh-2).
- Browser test by hand: zone picker renders per state, zone_id
persists, reload shows saved zone, computed styles on rendered
.zone divs match expected geometry.
