 ## Phase 11 — Public Site Enhancements
 
+### 11.B — `ReleaseRoutes` resolver + repoint
+
+**Landed:** 2026-06-16 on dev.
+
+- **What:** New shared `DeepDrftPublic.Client/Common/ReleaseRoutes.cs` — the single source of truth for resolving a release to its dedicated detail route. `ReleaseRoutes.DetailHref(long id, ReleaseMedium)` returns `/cuts/{id}`, `/sessions/{id}`, or `/mixes/{id}`; a convenience overload `DetailHref(ReleaseDto)` delegates to the primary. `ArchiveView`'s former private `DetailHref` switch was removed and replaced by this shared resolver. The player-bar title (`TrackMetaLabel`), Archive cards, and `AlbumsView` Cut cards all route through the shared resolver. A thin `/tracks/{id}` redirect page (`Pages/TrackRedirect.razor`) handles bare-release-id deep links: it fetches the release to discover its medium, resolves through `ReleaseRoutes.DetailHref`, and performs a history-replacing redirect — one medium→route table, no second source. The track-cardinal stack (`TrackDetail`/`TracksView`/etc.) was deliberately not touched — that is 11.C.
+- **Why:** Multiple call sites (Archive, AlbumsView, player bar) each maintained their own medium→route mapping. A fourth medium or a route rename would require hunting all of them. Centralising into one static helper makes the medium→detail-page contract explicit in one place and removes the risk of call sites drifting.
+- **Shape:** `ReleaseRoutes.cs` (new, `DeepDrftPublic.Client/Common/`): static class, two `DetailHref` overloads. `ArchiveView.razor`: private `DetailHref` switch removed; calls delegate to `ReleaseRoutes.DetailHref`. `TrackMetaLabel.razor` and `AlbumsView.razor.cs`: updated to call `ReleaseRoutes.DetailHref`. `TrackRedirect.razor` (new, `DeepDrftPublic.Client/Pages/`, route `/tracks/{Id:long}`): fetches release via `IReleaseDataService.GetById`, resolves through `ReleaseRoutes.DetailHref`, navigates with `replace: true`; falls back to `/cuts` on unknown id.

 - **11.F — queue model.** `IQueueService` above the single-slot player + one new player `TrackEnded` hook + player-bar skip controls. **Free-floating, can start cold day one.** Gates the Cuts "play album" affordance (11.A header Play). **Preload (§1.3 half b) stays OUT** — design the seam, defer the feature.
 - **11.G — release Description schema slice.** New `ReleaseEntity.Description` column + EF migration (**Daniel-gated apply**), `ReleaseDto` mirror, `TrackConverter` round-trip, write-path plumbing (`UpdateTrackMetadataRequest` + upload form + the unified services, threaded wherever `Genre` is), CMS `AlbumHeaderFields` multiline input (§3d). **Free-floating, can start cold day one** — the only gate is Daniel's migration go-ahead. The **detail-page render is NOT in this wave**: the Cut text block rides 11.A, the Session/Mix block is a small additive touch to those existing pages. Both degrade cleanly (null Description renders nothing), so render & schema can land in either order.

The §3.4 PlayAlbum→`IQueueService` seam (deferred in 11.A, awaiting 11.F) is now closed: `CutDetail.razor` consumes the cascaded `IQueueService` — header Play calls `Queue.PlayRelease(ViewModel.Tracks, 0)`, per-row play calls `Queue.PlayRelease(ViewModel.Tracks, index)`, currently-playing row toggles play/pause, null-safe fallback to `SelectTrackStreaming` when the queue cascade is absent (2026-06-16).

 **Dependency shape:** `11.A → 11.B → 11.C`; `11.B → 11.E`; **11.D, 11.F, 11.G parallel** (11.D coordinates with 11.C on `ArchiveView`; 11.F's "play album" is consumed by 11.A; 11.G's Description render rides 11.A + a Session/Mix touch, degrading on null). The cold-start items are **11.A**, **11.F**, and **11.G** — kick 11.A + 11.F off first so "play album" works on first ship of the Cut page; 11.G runs alongside on its own track.
