 - [Phase 13]: 13-03: the wishlist item-added branch extends albumAddedCallback; the digest upsert is ON CONFLICT ... RETURNING (xmax = 0) and only the row-creating insert dispatches the 1800 s wishlist_digest job (no worker until Phase 14)
 - [Phase 13]: 13-03: job queues called inside GORM callbacks get jobDB (a fresh statement); a bare cleanSession handle replays the triggering insert under WithContext+Create
 - [Phase 13]: 13-03: the purchase emits the moved album's updated event before the bells (PHP sync order); multi-publication goldens compare order-insensitively
+- [Phase 13]: 13-04: PHP decodes ISO-8859-2 CSV uploads as Windows-1250 (iconv //IGNORE never fails); the Go parser keeps that, so letters that differ between the encodings import wrongly in both
+- [Phase 13]: 13-04: ReleaseFetcher returns the mapped Discogs draft; the Phase 13 default fails (discogs_unavailable), Phase 14 installs the real one with SetReleaseFetcher
+- [Phase 13]: 13-04: CSV uploads live in the private bucket golem15.fonoteka.csv.bucket_url (default file://./storage/app) under fonoteka-csv/<uid>/<uuid>.csv
