Version every /api route to /api/v1 (251 controller routes + ~24 Location
headers + the scanner callback URL + the Startup request-log literal),
uniform across the machine API, auth, scanner and scripted-build surfaces.
Add ApiVersionRewriteMiddleware: a legacy unversioned /api/* request is
rewritten (NOT redirected) to /api/v1/* in-pipeline — method, body, auth
headers and query survive — carrying RFC 8594 Deprecation/Sunset headers,
so curl / the future MCP server / bookmarks keep working. An already-
versioned path passes through; a future /api/v2 is never forced to v1.
Standardize the route convention (leading-slash absolute route per method,
no class-[Route] — except the two Scanner/Scripted controllers whose ~all
actions share a parametrized {id} prefix), enforced by ApiRouteVersioningTests
(^/api/v\d+/ over the whole Controllers.Api surface; browser-nav
/auth/oidc/login is out of scope).
Regenerate v1.json (160 paths, all /api/v1)/endpoint-index/v1.d.ts; sweep 945
SPA request literals + the test mocks (regex + positional URL parsers). /api/v1
is additive-only after freeze; the legacy-rewrite shim sunsets in ~2 releases
(owner decision) with removal tracked as a Phase-3 follow-up.

Fans the frozen ETag/If-Match/412 recipe (Block reference, #253) onto the
Playlist aggregate:
- ReplacePlaylistItems command carries ExpectedVersion; the handler runs
CheckVersion as a standalone Either after validation (so a stale write
survives as 412, not flattened to 422 by Apply/Join), bumps Version
unconditionally before saving, and persists via
SaveChangesWithConcurrencyGuard (EF concurrency-token backstop).
- PlaylistViewModel carries Version; the items GET sets a strong ETag and
the PUT parses If-Match, threads it into the command, and returns the
refreshed ETag on success (400 on a malformed If-Match).
- Sibling item-adding handlers (AddItemsToPlaylist, AddMovie/Episode/
Season/ShowToPlaylist) bump Version too, since they mutate the same
editor-visible item list.
- SPA: playlists.ts exposes getPlaylistItemsWithMeta and an
If-Match-aware updatePlaylist; PlaylistEditor holds the ETag in a ref,
round-trips it on save, and opens a "changed elsewhere" ConfirmDialog on
412 (mirrors BlockEditor).
Tests: new ReplacePlaylistItemsHandlerConcurrencyTests (stale/match/
force-write/no-op-bump/racing-save), new PlaylistController tests
(ETag on GET items, 400/412/thread-version/force-write on PUT), and a
vitest 412-conflict-dialog test for PlaylistsScreen. dotnet test:
1304/1304 green. web: npm run typecheck clean, npm run build clean,
vitest 664/664 green.
Ref #253 PR2.
Adds DecoController (groups + decos CRUD + full-state PUT), playlist and
artist/multi-collection search picker wrappers, a PlaylistController for the
break-content playlist cascade, and PUT /api/playouts/{id}/deco. Fixes the
CreateDecoHandler missing deco-group existence check (FK 500 -> 422), matching
the CreateBlock/CreateTemplate precedent. ReplaceDecoRequest.ToCommand rejects
Merge on the non-mergeable sections (422).
