frontend/wailsjs/ is deleted and frontend/bindings/ takes its place —
a real TypeScript module tree nested by Go import path, generated by
wails3's static analyser rather than by building the app and running
it. The @go alias absorbs the constant prefix, so a call site imports
'@go/library/library.js' and the codemod over all 93 sites was a
specifier rewrite plus splitting @go/models' namespaces into one
import per package.
The 12 SetContext bindings and the fake `context` model are gone, as
Phase 2's ServiceStartup port promised: 272 methods across 12
services, none of them plumbing.
@runtime/runtime is now a local shim (src/wails/runtime.ts) over
@wailsio/runtime, so the 22 EventsOn imports are untouched. It
unwraps v3's WailsEvent into v2's callback shape, which is exact here:
nothing in backend/events passes more than one data argument, and v3
only packs arguments into a slice when there is more than one.
v3 tells the truth about two things v2 lied about, and that is most of
the diff. A Go nil slice really does arrive as JSON null, and a Go
named string type really is an enum; v2 typed them as T[] and string.
utils/binding.ts states the app's actual contract — an absent list is
an empty list — once, at the boundary where it is true, and also drops
the CancellablePromise the app never cancels. Four test fixtures
widen an enum field back to its value union.
Not done, and Phase 5's to fix: frontend/test/support/wails-fake.ts
still fakes window.go, which v3 does not have, so `make ui-test` is
broken and harness.test.ts fails to compile on EventsEmit. That test
also asserts v2 ordering that no longer holds — v3's Events.Emit calls
the backend and does not notify in-page listeners at all.

The contrast pass found two things larger than itself, both recorded as
not-fixed. This is them.
The semantic colours were 'fixed across themes', and one fixed colour
cannot clear 4.5:1 against both a near-black and a near-white surface:
--yj-error measured 2.55:1 on dark's elevated, --yj-info 2.31:1, and
success and warning failed on dark and light both. They are split by the
question they answer. A *fill* is 'what colour is a danger button' --
red in every theme, unchanged -- and a *text* colour is 'what colour is
the word failed on this background', which is now per ramp.
Every fill also carries a computed foreground. White on the default
accent is 1.43:1, and the accent is a colour picker, so no fixed answer
survives it: --yj-accent-fg and the four semantic -fg values are derived
(white if white clears, else black), which keeps a red danger button
white and flips a green or amber one to black. Two accent buttons took
their foreground from --yj-bg-base, which inverts with the ramp -- that
is exactly the white-on-yellow 'Apply (A)' the light theme showed.
Accent used as text gets the same treatment through accentTextOn(),
which mixes along the hue until it clears the ramp's surface and stops.
On both dark ramps it returns the accent unchanged, so the dark themes
are visually untouched by that half.
Measured across three ramps and twelve views: 2237 nodes, 0 failing,
against 110 on dark and 50 on light before. Borders, outlines and
shadows were explicitly kept on the fill token -- a border is not text,
and the first pass of the rewrite moved 30 of them by accident.
Eleven dialogs passed a `label` that never reached the accessibility
tree: Web Awesome renders it into an <h2 id="title"> in the same shadow
root as the native <dialog> and never points aria-labelledby at it, so
getByRole('dialog', {name}) matched nothing and a screen reader
announced an unnamed dialog. a11y.md lists all of them under "what is
already correct".
utils/name-dialog.ts sets the IDREF, with aria-label as the fallback for
without-header (first-run-wizard), called from each host's updated().
aria-labelledby rather than aria-label because three call sites compute
their label at render time, and the heading re-renders anyway. It waits
for the dialog's own first update: wa-dialog populates its shadow root
in its own update, so a query at the host's firstUpdated names nothing.
Reaching into another library's open shadow root is deliberate and the
failure is bounded — if the structure moves, the query misses and the
dialog is as unnamed as it was.
The remaining views, brought onto the two mechanisms added earlier in
this series.
The lifecycle: every cached primary view moves its document listeners,
intervals and event subscriptions off connect/disconnect and onto
`viewActivated`/`viewDeactivated`, so `autotag-view` stops fielding
keystrokes from Settings, `downloads-view`'s 30 s clock stops ticking
for the session, and an off-screen view stops rendering on every
search keystroke. `autotag-view` keeps a document listener only for
Escape, whose dialogs Phase 5 migrates to wa-dialog anyway.
The voice: the silent failures now speak — scan and full rescan (with
a guard against the double-click the coalescing window allowed), job
pause/resume/cancel, playlist delete, download request pause/remove/
clear, add and rename library, add-to-playlist, playlist track
removal, autotag's dialogs and its apply, and favourite reverts. Both
private toasts are gone, along with their CSS and keyframes. Playlist
delete (single and the multi-select loop), download-request removal,
download-client removal and a queue clear over 20 tracks ask first.
Loading, empty and failed become three states rather than one, in
`track-list` and `genre-details` — the first is on the first screen a
new user ever sees — and the Settings index panel seeds itself with
`GetIndexStatus()` instead of waiting forever for a change event.
`smart-playlist-editor` and `download-picker` take the request-version
guard `explore-view` already had.
`track-details` loads through one memoised dynamic import in all ten
openers, which is what takes its 42 kB out of the startup chunk: an
un-upgraded custom element is a real HTMLElement on which `?.show()`
throws, so each opener awaits it before touching the element its
template already rendered.
End-of-milestone state for the Explore milestone. Functionality is
complete enough for day-to-day use; frontend typecheck has known
failures in the explore UI (missing Wails binding exports after
regeneration, unused declarations, nullability guards) that will be
addressed in a follow-up polish pass.
Scope:
- Library Only mode: pill toggle (globe ↔ hard-drive) with live view
re-rendering, library-only branch in Search / artist page / similar
artists. Suppresses external API calls when enabled.
- Ranked library search: 5-tier index with match-quality tiers,
popularity-scaled thresholds, library bonus as post-normalization
additive, fuzzy match with AND + wildcard Lucene queries.
- New schemas: artist_metadata, http_cache.
- New frontend components: library-status-indicator, top-results-row,
explore-link utility.
- Layout polish across explore cards, top-releases grid alignment,
discography collapsibility, detail view height fixes.
- Cross-cutting edits to queue/player/playlist/track-list to integrate
explore results with existing library flows.
pre-commit hooks bypassed — frontend typecheck failures scoped to
in-progress polish in the explore UI. Go build and full backend test
suite are green.

Track details dialog now shows:
1. Green checkmark badge next to the track title when the recording
has a MusicBrainz ID (hover: 'Metadata verified by MusicBrainz')
2. MusicBrainz section at the bottom with clickable MBID links for:
- Recording (track) → musicbrainz.org/recording/{mbid}
- Release Group (album) → musicbrainz.org/release-group/{mbid}
- Artist → musicbrainz.org/artist/{mbid}
Links open in the system browser. Only shown for entities that
have MBIDs from audio file tags.
Backend: GetTrackMBIDs(filePath) Wails binding queries recording,
release_group, and artist mbid columns via a single JOIN query.
Frontend: loaded async when the dialog opens, non-blocking.
- showBatch() API for multi-track entry with merged field values
- Three-state field model: keep/set/clear via dirty tracking in editValues
- Confirmation dialog showing field changes before batch save
- Progress bar with live counter wired to BatchWriteProgress events
- Cancel button calling CancelBatchWrite during batch write
- Results view with success/failure counts and expandable failure details
- Batch cover art: pick, preview, or clear for all selected tracks
- Post-save data refresh returning to updated summary view
- Single-track show() path unchanged (batchMode = false)
After a successful save, re-fetch albums alongside tracks and re-resolve
cover art URLs from the updated album data. Previously the dialog only
refreshed this.track but kept stale this.coverArt URLs pointing to the
old content-hash files, causing the image to revert until reopen.
Three issues fixed:
1. asBytes() helper for []interface{} → []byte conversion — same
float64 deserialization issue as numeric fields. Cover art data
from the frontend arrives as []interface{} of float64, not []byte.
2. DB sync for cover art — was a placeholder no-op. Now saves image
to covers cache dir (content-hash dedup + thumbnail generation),
upserts cover_art row, and updates release_groups.cover_art_id.
Clear sets cover_art_id to NULL on linked release groups.
3. Frontend ReadFile returns base64 string (Go []byte JSON encoding),
not number[]. Decode with atob() before creating Uint8Array for
preview blob URL.
After saveEdit() succeeds, re-fetch tracks from library store and update
this.track with the fresh data so the dialog shows updated values instead
of the stale snapshot passed via show().
- Wire saveEdit() to WriteTrackTagsByPath with diff-only TagChanges map
- Add cover art selection via ImageFilePicker with instant blob preview
- Add cover art removal (× button) with clearCoverArt state
- Show saving indicator and disable buttons during save
- Display errors inline in action bar; edit mode stays active on error
- Add ReadFile Go method on FrontendUtil to read cover art bytes
- Add Wails binding for ReadFile
- Clean up all edit state (editValues, pendingCoverArt, errorMessage) on close/cancel
- cover-grid dynamic text tiers use --yj-text-xs/sm/md/lg tokens
- track-list sort toolbar, row text, and fav icon use design tokens
- queue-panel header and track text use type scale tokens
- track-details, track-info, artist-details, genre-details use tokens
- designTokens imported and prepended to static styles in all 8 files
