'sami matar' was a wing-it FALLBACK stub — a placeholder the discovery pipeline
makes when it can't resolve a track to real metadata (no album, no cover). The
live sync explicitly skips wing_it_* ids for the wishlist (no metadata to act on),
but my re-add didn't — so it stored a coverless, single-classified placeholder.
That's why: sync didn't add it, no images, marked single.
Fix (parity): reconstruct refuses ids starting 'wing_it_'. Frontend renders the
'-> Wishlist' status as plain, non-clickable text for wing-it rows (with a tooltip)
since they were never actually wishlisted. Real tracks keep the working button +
the byte-identical-payload re-add from the prior fix.
Root cause (the real one): the auto-add passes original_tracks_map[id] — tracks_json
run through a specific normalization (album->dict with images/album_type/total_tracks/
release_date, artists->dicts). My re-add hand-rolled a different shape, so the stored
spotify_data didn't match and the wishlist's nebula (which reads spotify_data.album.
images[0].url) had no cover, plus album/single classification could differ.
Fix: extract that normalization into one shared build_original_tracks_map() and use it
in BOTH the live sync (core.discovery.sync) and the re-add. The re-add now resolves the
track by source_track_id through the same map — byte-identical payload. Verified on a
real sync row: re-add payload == live-sync payload, album.images present. (The shared
normalizer is also copy-safe, fixing a latent tracks_json mutation in the old inline
version.)
Fallback (track absent from tracks_json) rebuilds through the same normalizer with the
cover seeded from the row's image_url. 10 tests incl. a direct parity assertion.
The re-add showed no album/single art. Cause: reconstruct returned the full track
from tracks_json AS-IS — and some syncs store tracks_json lean (no album.images),
so the re-added wishlist entry had an empty album.images even though the track's
cover was sitting right there in the track_result's image_url.
Fix: always backfill album.images from the track_result's image_url when the album
has none (and copy the dict so tracks_json isn't mutated). Real album art is kept
when present; the 250px thumb only fills a gap. Verified against a real sync row in
all three cases (full / lean tracks_json / no tracks_json) — album.images now
populated in every one. The wishlist card reads album.images, so the cover shows.
In the dashboard Recent Syncs detail modal, the '→ Wishlist' status on unmatched
tracks is now a button. Clicking it re-adds that exact track to the wishlist with
the SAME context the sync used (source_type='playlist' + the playlist's name/id +
failure_reason), so it's indistinguishable from the original auto-add.
- reconstruct_sync_track_data() (pure, tested): prefers the full cached track from
tracks_json (by source_track_id, then index) so album art/full data carry over;
falls back to the track_result fields; refuses non-'wishlist' rows and rows with
no id (can't re-wishlist a matched/unidentifiable track).
- POST /api/sync/history/<id>/track/<i>/wishlist resolves the entry server-side and
calls the wishlist service; idempotent (reports added vs already-on-wishlist).
- button shows a busy state then '✓ Re-added' / '✓ On wishlist'.
7 pure tests (full-track preference, id-vs-index match, fallback rebuild, non-
wishlist + out-of-range refusal). JS/PY/ruff clean.
