genre_review_service.run() and dedup_review_service._run_scan() both
unconditionally created a new run row even when the underlying job never
actually executed (skipped_lock, or any other non-success status). For
genres this was directly user-visible: the review page always shows the
most recent run, so a skipped click created an empty run that displaced
the real previous preview, making it look like every pending change had
vanished. Both now return None (persisting nothing) when the job didn't
succeed, and both routers surface a "didn't run, something else was
using the pipeline" notice instead of silently redirecting. Cleaned up
the one phantom empty genre_runs row already sitting in production,
restoring the real 20-change preview.
Also added a "Run now" button to each row on the Playlists list page
(previously only on a playlist's own detail page), for the common case
of adding new tracks and wanting to sync immediately.
dedup-library.sh: additive --json (one NDJSON line per candidate deletion
to stdout, alongside the unchanged human log) and --only-paths FILE (in
--apply mode, only actually delete entries whose path is in FILE; without
it, --apply deletes everything as before -- existing direct callers are
unaffected). Without --only-paths the safety re-verification is free:
--apply --only-paths re-runs all 4 passes from scratch on every invocation,
so if a group's ranking changed since a scan (e.g. the old keep_path is
gone), the fresh pass assigns the previously-"delete" path the KEEP role
instead and the only-paths allowlist naming it is simply never consulted --
no duplicate ranking logic needed in the review service.
spotify-genre.py: additive --json emitting one JSON line per genre change
(dry-run or --apply) for genre_review_service to persist.
pipeline_runner.run_job_capture(): like run_job() but captures stdout as
text (still under the same shared lock, still writes a job_runs row) for
callers that need to parse structured output rather than just log it.
dedup_review_service.scan() persists dry-run candidates into
dedup_runs/dedup_candidates. confirm_and_apply() re-checks confirmed
candidates still exist before invoking --apply --only-paths, so nothing is
ever deleted without an explicit confirm -- matches the false-negative-
biased dedup preference. scheduler_service's maintenance:dedup job now
goes through this (still dry-run only, every day).
genre_review_service.run() wraps spotify-genre.py for both dry-run preview
and the real scheduled --apply run, persisting every run's diff into
genre_runs/genre_candidates either way -- genre writes keep their current
auto-apply behavior (low-risk, reversible, GENRE_LOCK-protected) but are
now reviewable after the fact. lock_artist_genre() gives a one-click revert
path when a run gets something wrong.
Added minimal routers+templates for /dedup (scan, review, confirm-and-
delete) and /genres (preview, review, lock-old-genre).
Verified end-to-end against REAL duplicate files (not mocked): built an
actual FLAC+MP3 duplicate pair in a real beets library, ran dedup-library.sh
--json and confirmed correct JSON output, verified --apply --only-paths
with an empty confirm list deletes nothing and with the real confirmed path
deletes exactly that file (DB + disk) while preserving the FLAC, and ran
the full dedup_review_service scan->confirm->apply flow through the same
fixture. genre_review_service and spotify-genre.py --json verified against
mocked/direct output (spotify-genre.py's own artist-genre lookup needs a
live Spotify API call, out of reach in this sandbox). Confirmed the full
app boots with all five routers registered.
