Operator hit 3 large PNGs stuck in 'processing' for 2 days 2026-05-25:
the existing recover_interrupted_tasks flips processing > 5min back to
queued + .delay(), but if the underlying file is unfixably broken (e.g.,
PIL OSError, also patched in 68cffce), the loop never terminates and the
'Scanning...' banner sticks at 0/0 forever blocking new scans.
/api/import/clear-stuck:
- Flips every task in pending/queued/processing to 'failed' with a clear
marker error message
- Finalizes any 'running' ImportBatch that has no remaining active children
- Idempotent + non-destructive: rows survive, can be retried once the
underlying cause is resolved
UI button 'Clear stuck...' sits next to 'Retry failed' / 'Clear completed'
with a warning-tonal alert in the confirm dialog explaining what it does
and recommending Retry failed once the cause is fixed.
Tests: clears mixed non-terminal states, untouches complete rows,
finalizes orphan batch, no-op when nothing stuck.

MaintenancePanel hosts: backfill + centroid recompute trigger cards,
the five suggestion-threshold sliders (autosave on slider release),
the allowlist table (inline editable min_confidence, delete), and the
alias table (mapping display, delete). Wired as a third Settings tab,
ML settings loaded lazily when the tab opens.

ImportTriggerPanel shows an active-batch progress indicator when scan_directory
is running, or a "Quick scan" button otherwise. Deep scan deferred to FC-2d
is called out in the panel text so it's not a surprise.
ImportFiltersForm autosaves on blur/change so there's no Submit button. The
transparency and single-color sliders gate on their respective switches.
ImportTaskList uses v-data-table-virtual for performance on long histories,
with status filter, retry-failed, and a clear-completed dialog with age
buckets. Status chips are color-coded via FabledDesignSystem semantic
tokens (success/warning/error/accent/info).

Overview tab shows total images/tags/storage/pending/failed using
Fraunces for the big numbers. Inline alert nudges the operator to the
Import tab when pending tasks exist. Polls /api/system/stats every 5s
while the tab is visible (pauses when the document is hidden).
Import tab references three placeholders (TriggerPanel/FiltersForm/
TaskList); real implementations land in Task 15.
Router replaces the placeholder view for /settings with SettingsView.
