timothy	fba5233caf	feat(610): split the decision corpus into one YAML-frontmatter file per record ... 168 records -> docs/decisions/records/<area>/<topic>.md (163 active, 23 dirs) and docs/decisions/archive/<area>/<topic>.md (5 archived). The filename IS the key, so one-active-record-per-key becomes a filesystem property rather than a validator check, and supersession becomes a `git mv`. WHY: the monolith was a concurrency problem before an aesthetic one. A 3,900-line append target made parallel sessions collide -- PR #605 and PR #614 both hit append-vs-append conflicts during routine rebases, and hand-resolving those inside the corpus is exactly the operation the rationale-rewrite guard exists to police. HOW IT IS VERIFIED: a ~170-file diff cannot be meaningfully read, so correctness does not rest on reading it. The parser was taught BOTH formats first, so the body-diff guard parses the old form at the merge-base and the new form at head -- the migration validates itself, no bypass. The proof is a field-level equivalence harness: 168 records before and after, zero lost, zero gained, zero field mismatches, zero rationale bodies differing. Reviewers should scrutinise the harness; it is the actual evidence. What measuring caught that reading would not have: - ~500 lines sit OUTSIDE any record -- decisions.md's lifecycle schema and each topic file's preamble, mostly the only copy. Source files are kept and stripped, never deleted. They also cannot be filed per-area: topic files hold several areas and 4 of 23 areas span several files. - Archive discovery was a non-recursive glob; after the split it found ZERO archived records, surfacing as four bogus "supersedes points to unknown key" errors rather than an obvious failure. - ~32 live docs point into the corpus BY DATE, which the split dangles. Each stripped file now ends with a generated "Records formerly in this file" index, which also rescues the identical breadcrumbs in old issue comments. - decisions.md's "In this file:" list was 97 same-file anchor bullets that the split makes WRONG, not merely stale. Dropped; the generated index replaces them with links that resolve. The equivalence harness now runs against a checked-in FIXTURE, not the live corpus. The earlier version migrated the real tree, which made it a one-shot: the moment the migration landed there was nothing left to move and the tests failed for reasons unrelated to the code. A fixture keeps them testing the SCRIPT rather than the repo's current state. Keys preserved verbatim, warts included: `sched` (12) and `scheduling` (1) remain two directories for one concept. Renaming a key is not a move -- it changes identity, breaks the equivalence proof, and invalidates MemPalace's per-key drawers. Taxonomy normalisation is separate work. refs #610	2026-07-25 19:45:09 +02:00
timothy	64decd492e	fix(496): give music videos a per-library server identity; itemId diff + soft trash ... Music videos carried no server identity, so JellyfinMusicVideoLibraryScanner had to reconcile by a (LibraryPathId, path) diff and HARD-delete the remainder. A file served by two libraries with overlapping local paths is a single row owned by whichever library scanned it first, so that owner's sweep destroyed a row another library still served — taking collection membership and playout references with it, irreversibly. This is #494's deferred "option 2": - New JellyfinMusicVideo : MusicVideo (ItemId/Etag), mirroring JellyfinMovie — TPT table, varchar(36), ItemId index. Dual-provider migration Add_JellyfinMusicVideo. - New IMediaServerMusicVideoRepository + JellyfinMusicVideoRepository: itemId-keyed existing-set/lookup and Flag{Normal,Unavailable,FileNotFound} seams, all scoped per library via LibraryPath.LibraryId. - New MediaServerMusicVideoLibraryScanner base; JellyfinMusicVideoLibraryScanner folds onto it and keeps the #177/#488/#497/#500 metadata-reconcile logic verbatim. - The sweep now soft-trashes (FileNotFound) instead of deleting, so removal is reversible and EmptyTrash-governed. DeleteEmptyArtists consequently no longer fires from a sweep. - Pre-identity rows are ADOPTED in place: the identity row is inserted against the same MediaItem id, scoped to the scanned library's own LibraryPath, so collection membership survives and a local/second-library row is never hijacked. - AddMusicVideo normalizes Path/PathHash to the path-REPLACED local path; the projection fills them from the server-reported path, which would break every later PathHash lookup. Docs: scan.musicvideo-reconciliation relocated to docs/decisions/archive/scan.md as superseded; new active record scan.musicvideo-server-identity. fixes #496	2026-07-25 17:20:53 +02:00
