 Daniel tested the landed Phase 9 surface end-to-end and produced a punch-list of corrections before the phase is called complete. These are **not new features** — they are the gap between what the Wave 1–7 specs *built* and what hands-on use *wants*. The theme is the same one Phase 9 has carried throughout: the medium taxonomy reaching every surface it should, and the browse surfaces matching the mental model rather than the implementation's first cut.
 
-Two surfaces dominate: the **CMS Release Archive** (the card-grid landing is the wrong shape — Daniel wants medium *tabs*, not navigate-away cards) and the **public Archive** (the three-card overview is dead weight; the searchable all-releases view should *be* the archive). A third item — the **Mix Visualizer redesign** — is explicitly **not specced here**: Daniel wants to be interviewed first. It is carried as a design-pending track with an interview question set in `product-notes/phase-9-mix-visualizer-redesign.md`.
+Two surfaces dominate: the **CMS Release Archive** (the card-grid landing is the wrong shape — Daniel wants medium *tabs*, not navigate-away cards) and the **public Archive** (the three-card overview is dead weight; the searchable all-**releases** view *is* the archive — release-cardinal, decided). The **Mix Visualizer redesign (8.K)** is **pulled out of Phase-9-completion scope** — Phase 9 closes without it — but is now **documented in full**: the interview ran and `product-notes/phase-9-mix-visualizer-redesign.md` is a finished, implementation-ready design spec for a post-Phase-9 wave.

+**Open questions resolved (Daniel, 2026-06-13):** 8.H is decided **H2** (a new release-cardinal searchable browser at `/archive`; cascade: `/tracks` demoted from nav, route kept; mobile ARCHIVE → the browser; three-card overview fully retired); 8.I drops GENRES from the nav only (route kept); 8.F makes the Session hero optional-but-warn-if-missing; 8.E defaults the `ALL`-tab Add Track to Cut with the medium selector staying user-changeable. A new track **8.L** consolidates the release-name/track-name pair into a single name for single-track media.

@@ -178,19 +180,20 @@ Full track decomposition, acceptance criteria, and parallel/dependent analysis:
 - **8.B — `ALL` tab: all-releases grid with edit.** Left-most tab showing the current cross-medium releases grid with working edit buttons — the surface the retired Releases toggle used to show.
 - **8.C — Per-medium grids gain working edit affordances.** Cut / Session / Mix tab grids each get an Edit action routing to the correct edit page for that medium. *(Parallel with 8.D, 8.E once 8.A lands.)*
 - **8.D — Type chip reads "Session" / "DJ Mix" for non-Cuts.** The cross-medium grid's Type column must not show a Cut-only `ReleaseType` chip for Session/Mix rows. *(Independent.)*
-- **8.E — Add-Track buttons in all modes, medium-aware routing.** Every tab surfaces an Add Track button routing to the upload page pre-set to that tab's medium. *(Depends on 8.A.)*
-- **8.F — Session hero image in the upload form (retire the two-step).** Compose the hero-image field into the Session upload form so a Session is authored in one pass; remove the "set it later from the browser" alert. *(Independent of the tab work; touches the upload form + the resource-addressed hero endpoint ordering — see note.)*
-- **8.G — "Album Name" → "Release Name" label.** Rename the `AlbumHeaderFields` label. *(Independent, trivial.)*
+- **8.E — Add-Track buttons in all modes, medium-aware routing.** Every tab surfaces an Add Track button routing to the upload page pre-set to that tab's medium. The `ALL`-tab Add Track defaults to **Cut**; the medium selector stays user-changeable after landing on the form. *(Depends on 8.A.)*
+- **8.F — Session hero image in the upload form (retire the two-step).** Compose the hero-image field into the Session upload form so a Session is authored in one pass; remove the "set it later from the browser" alert. Hero is **optional but warns if missing** (no hard gate). *(Independent of the tab work; touches the upload form + the resource-addressed hero endpoint ordering — see note.)*
+- **8.G — "Album Name" → "Release Name" label.** Rename the `AlbumHeaderFields` label. *(Independent, trivial. Sequence before 8.L.)*
+- **8.L — Consolidate release name + track name for single-track releases.** For Session/Mix the form presents **one** name field (Release Name); the underlying track name is derived from it (recommended: kept synced on create and edit so they never diverge). Cuts (multi-track) are unaffected. Blast radius (discovery done): CMS `BatchUpload` single-track branch, `BatchEdit` via `BatchTrackDetail`, and the legacy `TrackNew`/`TrackEdit` forms *if still live*; the public detail/gallery views already key off the release title only (no public work). *(Pairs with 8.G/8.E/8.F — same upload/edit forms.)*
 
 **Public site (`DeepDrftPublic.Client`):**
-- **8.H — Archive page becomes the searchable all-releases browser.** Retarget `/archive` from the three-card overview to the searchable all-releases view; this *is* the archive. Resolve the track-vs-release framing (see open question). *(Depends on the framing decision; see note.)*
-- **8.I — Nav slimmed: ARCHIVE + three medium modes inline, GENRES removed.** Above the medium breakpoint the appbar carries ARCHIVE (all-releases browser) and the three medium links directly; GENRES is eliminated from the nav. *(Depends on 8.H for the ARCHIVE target.)*
+- **8.H — Archive page becomes the searchable all-releases browser (release-cardinal, decided H2).** Build a new release-cardinal searchable browser at `/archive` (search + medium/genre filter, cards → per-medium detail); retire the three-card overview on every breakpoint. Cascade: `/tracks` (`TracksView`) is demoted from the nav (route kept reachable); mobile ARCHIVE → the new browser. *(Gates 8.I.)*
+- **8.I — Nav slimmed: ARCHIVE + three medium modes inline, GENRES removed.** Above the medium breakpoint the appbar carries ARCHIVE (the new release-cardinal browser) and the three medium links directly; **GENRES is removed from the nav only** (route + `GenresView` kept reachable). *(Depends on 8.H for the ARCHIVE target.)*
 - **8.J — ARCHIVE popover click does not close (bug).** Clicking a popover child leaves the pure-CSS hover dropdown stuck open on SPA navigation. Fix the dismissal. *(Independent bug fix.)*
 
-**Mix Visualizer:**
-- **8.K — Mix Visualizer redesign. `[design pending interview]`.** Daniel wants a scrolling high-resolution waveform (bottom-to-top) with a slider coupling scroll-speed to zoom/resolution. He has **explicitly asked to be interviewed before this is designed.** No implementation spec exists or should be written until the interview runs. Question set: `product-notes/phase-9-mix-visualizer-redesign.md`.
+**Mix Visualizer — out of Phase-9-completion scope:**
+- **8.K — Mix Visualizer redesign. `[post-Phase-9, design-complete]`.** A windowed, playback-coupled, bottom-to-top scrolling waveform showing the currently-playing region; zoom couples to apparent scroll speed (Guitar-Hero model, anchored at 1 quarter note @ 180 BPM = 333 ms visible at max zoom); lava-lamp aesthetic (theme-aware gradients, glassy), **strictly read-only**; standard Canvas/WebGL, no tricks, well-commented. The datum analysis recommends switching the Mix loudness profile from a fixed 2048 buckets to **constant-time-resolution capture (~333 samples/sec)** so long mixes aren't under-sampled at max zoom. **Phase 9 closes without this**; it runs as a post-Phase-9 wave, dispatchable straight from the finished spec: `product-notes/phase-9-mix-visualizer-redesign.md`.
 
-**Dependency shape:** 8.B is the foundation for the CMS tab work (8.A consumes the shared grid; 8.C/8.E layer on once 8.A lands). 8.D, 8.F, 8.G are independent and parallelizable immediately. On the public side, 8.J is an independent bug fix; 8.H gates 8.I and rides an open framing question; 8.K is blocked on the interview and must not start until it runs.
