Add Track now appears on every Release Archive tab and pre-selects the upload form's medium via ?medium=… (ALL→Cut); the selector stays user-changeable on landing.
Render the rich CmsAlbumBrowser filtered per medium in the CUTS/SESSIONS/MIXES
tabs via an optional RowActions slot; retire the thin CmsMediumTable. Session
hero and Mix waveform actions preserved; ALL tab and TrackList unchanged.
Replace the navigate-away ReleaseArchiveBrowser cards and the redundant top-level Releases
toggle with an in-page MudTabs strip under the Releases mode: ALL (CmsAllReleasesGrid) plus
one enum-driven tab per ReleaseMedium. Sessions/Mixes browsers gain an Embedded flag that
suppresses standalone page chrome when hosted as tab content; CmsCutBrowser is the new
Cut-filtered grid. /tracks/sessions, /tracks/mixes, /tracks/archive stay reachable by URL.
Desktop flattens the ARCHIVE popover into inline appbar links above the medium
breakpoint; mobile keeps the indented sub-list under ARCHIVE. GENRES and /tracks
removed from nav only — routes (GenresView, TracksView) remain reachable by URL.
Retires the now-dead desktop hover-popover and its 8.J collapse-state machinery
(mobile drawer still dismisses on click).
CmsAllReleasesGrid self-loads the cross-medium release list so 8.A can host it as the ALL tab with no VM plumbing; TrackList's Albums mode renders it now. Preserves sort/delete/expand/edit and the 8.D Type chip.
Edit forms (BatchEdit/TrackEdit/TrackNew) show the guidance alert instead of an
inert picker, via an AllowHeroUpload flag. Missing-hero nudge is Severity.Warning;
null-ReleaseId hero drop is now logged.
Retire the three-card overview for a search + medium + genre browser over all
releases. Adds q/genre filter params to the api/release paged read path,
mirroring the existing api/track/page TrackFilter pattern.
Session upload now carries a deferred hero-image input; the submit handler
creates the release then POSTs the held hero to the existing resource-addressed
endpoint. Hero is optional with a non-blocking warn-if-missing gate. The
per-row hero upload in CmsSessionBrowser remains the replace/correct path.
HashSet<string> _collapsedDropdowns replaces single bool so each parent
tracks its own dismiss state independently. onfocusout added alongside
onmouseleave so keyboard users get the dropdown re-enabled without a
mouse pass after Enter-activating a child link.
BatchTrackDetail gains ShowTrackName parameter (default true); BatchUpload removes the
Track Name input on the single-track path; BatchEdit suppresses it there too. Both sync
_tracks[0].TrackName = _albumName on submit/save so names can never diverge. Cut path
unchanged.
Covers AlbumHeaderFields MudTextField label + RequiredError, and the matching
code-side validation messages in BatchEdit and BatchUpload for consistency.
Add dd-nav-item-collapsed CSS class toggled on child click to override the
:hover/:focus-within show rules. Cleared on mouseleave so hover-to-open
works normally on the next pass. Mirrors the existing CloseMobileMenu pattern.
Cut rows continue to show ReleaseType (Single/EP/Album). Session/Mix rows
now read from a MediumTypeLabels dictionary so a future medium needs only
one new entry, no markup change.
Promote the Session/Mix single-track rule from a CMS-form convention to a
domain invariant: declare cardinality as data in MediumRules, enforce it in
UnifiedTrackService before the vault write (no orphan), return 409, and read
the same rule in the batch-form collapse.
Mirror BatchUpload.OnMediumChanged: switching to Session/Mix trims the
track list to one row and hides the add-track affordance, enforcing the
§9.3 single-track invariant on the edit path. Cut releases unchanged.
