The Files page could only list a collection if the operator already
knew its name and typed it in. No "browse known collections" affordance,
no backend endpoint listing collections.
Closest approximation without new backend: pull registered files-trigger
collection_globs from the existing triggers list and surface them as:
- a <datalist> on the collection input for autocomplete
- chip buttons under the form that one-click set the input
Empty state copy points the operator at the Triggers tab. Backend
endpoint to list known collections directly is still a v1.1.10+ task.
Styling uses the F-U-004 :root tokens so it inherits the dark theme.
AUDIT.md anchor: F-U-003 (frontend-only; backend endpoint deferred).

Filesystem-backed blob storage as the fifth concrete trigger kind.
- `files::collection(c).{create,head,get,update,delete,list}` Rhai SDK
(blob in/out; metadata maps; missing-field throws naming the field).
- `FilesService` trait in picloud-shared; `FsFilesRepo` (atomic
write: temp→fsync→rename→fsync-dir→DB; single-pass SHA-256;
checksum-verified reads → Corrupted) + `FilesServiceImpl` in
manager-core. Metadata in Postgres (0018), bytes on disk under
PICLOUD_FILES_ROOT with 0o700 shard dirs.
- `files:*` trigger kind via the Layout-E pattern (0019: widen both
CHECKs + files_trigger_details), TriggerEvent::Files (metadata only,
no bytes), emit_files fan-out, dispatcher arm, admin endpoint
POST /triggers/files (reuses validate_trigger_target).
- AppFilesRead/AppFilesWrite capabilities → script:read/script:write
(seven-scope commitment held). AppPubsubPublish reserved for v1.1.6.
- Admin files API (list + delete) + dashboard Files view per app.
Cross-app isolation keyed on cx.app_id at every layer. ~45 new tests
(service in-memory, fs tempdir, bridge integration). No DB required
for the suite. publish_ephemeral and the orphan sweep stay deferred.
