+## Admin statistics
+
+The only admin interface is `/admin/v2`, also reachable from `/admin/`.
+**Statistics** shows listening totals, a timeline, artist/track/release rankings,
+and paginated history. Select an artist or track to see its listeners, then a
+listener to see their history within the same filters. The **Users** list links
+to each user's full statistics.
+
+Periods use UTC. Counts come from the synchronized `listen_event` history: a
+natural finish, half of a track, or four minutes qualifies as a play. Interrupted
+sessions under five seconds are not retained. Short retained sessions contribute
+to listened time but not play counts. The source filter separates this instance
+from synchronized devices. Artist rankings use recorded artist names, including
+featured credits; the same artist is counted once per event. Existing history
+remains available when its local audio file is deleted. Library and service
+cards show current instance totals, independently of the listening filters.
+
+Migration `m_0051_add_listen_statistics_indexes` adds time and content indexes.
+The old admin pages and `/admin/debug` are removed; first-run setup remains at
+`/admin/setup`.
+
+Regression checks:
+
+```bash
+node --test tests/*.test.cjs

+# Use a disposable PostgreSQL; this test creates connection-local temporary tables.
+FURU_STATISTICS_TEST_DATABASE_URL=postgresql://... cargo test postgres_statistics_drilldown_and_pagination -- --ignored
+```
+
+`tests/browser-statistics.cjs` additionally exercises a fresh disposable instance
+at `FURU_TEST_URL` (default `http://127.0.0.1:3018`) and seeds the disposable Docker
+container `furumi-statistics-test-pg`. It requires Playwright (or
+`PLAYWRIGHT_MODULE`) and Chrome (or `CHROME_PATH`). Never point this test at a
+live service.
+
+## Importing into playlists
+
+The player's download manager offers **Add downloads to a playlist** for file
+and folder uploads and torrents, as well as YouTube. Choose an existing owned
+playlist or create one before starting; leaving the choice empty imports only
+into the library. Selected audio tracks are appended after processing or manual
+approval, including files resolved to tracks already in the library.
+
+Migration `m_0052_add_import_playlist_destinations` persists the destination and
+completion receipts. Retries and restarts retain the choice, avoid duplicates,
+and do not re-add tracks subsequently removed by the user. A started batch keeps
+its destination for its remaining files.
+
+```bash
+node --test tests/import_playlists.test.cjs
+# Disposable PostgreSQL; both tests use temporary tables.
+FURU_IMPORT_TEST_DATABASE_URL=postgresql://... cargo test import_destinations -- --ignored

+
+`tests/browser-import-playlists.cjs` checks the file upload flow, database
+reconciliation and the torrent picker on desktop and mobile. It requires a fresh
+migrated instance with the import agent disabled at `FURU_TEST_URL` (default
+`http://127.0.0.1:3019`), the disposable PostgreSQL container
+`furumi-import-playlist-test-pg` with database `furumi_import_test`, and Playwright

 artwork, metadata enrichment, similarity indexing, and maintenance run as
 durable background jobs rather than blocking playback requests.
 
+The `lastfm_popularity` job defaults to **light** mode: it requests popularity
+only for tracks without a completed lookup or with a changed title or primary
+artist. Both matches (including zero counts) and explicit Last.fm “Track not
+found” results are skipped on subsequent light runs. HTTP errors, timeouts,
+invalid responses, and other API errors remain eligible for retry. A failed
+full refresh also makes that track eligible for the next light run.
+
+Choose **Full: refresh all visible tracks** in the task's admin parameters to
+refresh existing statistics and retry previous misses. The options endpoint
+`POST /admin/v2/api/jobs/lastfm_popularity/run-options` accepts
+`{"refresh_existing": true}`; an empty object, scheduled runs, and the ordinary
+run endpoint use light mode. Neither mode limits the number of tracks processed.
+An authoritative miss clears current statistics while preserving their history.

+## Folder context
+
+A folder is a storage location, not proof of a shared artist or album. It may contain unrelated tracks from different artists and releases, or a compilation with different performers. Normalize each file independently using its own tags and path hints. Prefer explicit tags over ambiguous folder names. Never copy another file's artist, album, year, genre, or release type merely because the files share a folder. If a value cannot be determined for a file, return null and lower its confidence instead of borrowing another track's metadata.
+
+Use shared album context only when the files' metadata clearly identifies the same release. Folder file counts describe that release only when the folder actually represents one release; they do not determine release type for a mixed folder. Organizational folders such as "Music", "Downloads", or "Альбомы и синглы" are not artist or album names and do not imply a release type.
