Closes#584. Quarantined files used to sit in ss_quarantine/ with a
thin sidecar — no UI, no recovery, no way to see what got dropped.
This adds the management surface the user needs without going to the
filesystem.
UI: new "Quarantine" button on the downloads page header opens a
modal with every quarantined file (filename, expected track/artist,
reason, when, size). Three actions per row:
- Approve (one-click): restores the file, re-runs the post-process
pipeline with ONLY the failing check skipped, lands in the library
with full tags + lyrics + scan
- Recover (legacy fallback): moves to Staging for thin-sidecar
entries that lack the embedded context Approve needs
- Delete: permanent removal of file + sidecar
Per-check bypass: context['_skip_quarantine_check'] = 'integrity' /
'acoustid' / 'bit_depth'. Skips ONLY the named check — other quality
gates stay live. No blanket bypass-all flag.
Sidecar expansion: move_to_quarantine now persists the full
json-serializable context via serialize_quarantine_context (drops
non-JSON-safe values, walks nested dicts/lists/sets, str-coerces
unknown objects) plus the trigger name. Existing thin sidecars are
detected and routed to Recover instead of Approve.
Pure helpers in core/imports/quarantine.py: list_quarantine_entries
/ delete_quarantine_entry / approve_quarantine_entry /
recover_to_staging / serialize_quarantine_context. 27 tests pin
every shape: orphan files / orphan sidecars / corrupt sidecars /
collision-safe filename restoration / full-context vs thin-sidecar
dispatch / json round-trip safety.
Four new endpoints in web_server.py — thin glue around the helpers:
GET /api/quarantine/list, DELETE /api/quarantine/<id>,
POST /api/quarantine/<id>/approve, POST /api/quarantine/<id>/recover.
Download modal status differentiates "🛡️ Quarantined" from
"❌ Failed" so recoverable files are visible at a glance — checked
against the error_message text, no schema change needed.
Pipeline changes are three minimal per-check conditionals at the
existing quarantine sites in core/imports/pipeline.py. Each
move_to_quarantine call now passes its trigger name so the sidecar
records which check fired.
Full suite: 2992 passed.
