Mirrors the music model (full_refresh vs smart incremental, plus deep_scan):
- incremental: only recently-added items from the server (Plex addedAt:desc /
Jellyfin DateCreated, capped); upsert; no prune.
- full: every item; upsert all (refresh metadata + add new); no prune.
- deep: every item; upsert; prune what the server no longer has (empty-scan
safety preserved).
scanner.request_scan/scan_sync take mode; /api/video/scan/request reads
{mode} from the body (default full); adapters take incremental=. Tests cover
deep-prunes / full-doesn't / empty-deep-safety / incremental-requests-recent.

"""Seam tests for the video library scanner (experimental branch).
|
|
|
|
The scanner is server-agnostic: it consumes a media source that yields
|
|
normalized dicts. We drive it with a fake source so the scan/prune/error logic
|
|
is fully tested without a live Plex/Jellyfin. Also guards that core/video/
|
|
imports nothing from the music database.
