Plans 013 and 014, the album page that prompted them, and the smaller
fixes they turned up. Changelog, largest first.
## The local library is shaped like files, not like MusicBrainz
`audio_files` carries its own tags and points at `albums` and
`artists`; `file_genres` is the one real many-to-many. `recordings`,
`release_group_recordings`, `artist_credit`, `artist_credit_artist`,
`recording_genres`, `release_groups` and `release_to_rg` are gone from
the local side, and with them a six-way join in every read, a
`MIN(release_group_id)` subquery in eleven queries and a
first-credited-artist subquery in nine. Measured on a real 25,966-file
library, every many-to-many that model expressed was 1:1 in the data.
- Ownership is a file. `GetFilePathsByRecordingMBIDs`,
`LibraryMBIDIndex.CheckMBIDs`, `collectLibraryEntities` and
`pruneStaleLocalCrossReferences` all join `audio_files`, so the 812
orphaned recordings, 216 release groups and 260 artists that library
carried are now structurally impossible.
- One projection: every track query selects from the `track_metadata`
view, one row type, one mapper. Nine hand-rolled copies had drifted
far enough to report different years on different screens.
- `library_id = 0` means every library, so each list query exists once
instead of scoped and unscoped with a branch at every call site.
- No migration chain. `sql/schemas/` is the one description of the
shape; `sql/migrations/`, `applyMigrations` and `schema_migrations`
are squashed away, along with the drift between them that had sqlc
generating against a stale schema.
- `database.InsertTestTrack` is the one test seeder; twenty test files
had been assembling the old FK chain each in its own order.
## The catalog stores its ids as bytes
`explore_index`'s three 36-char MBID columns and its entity-type text
are 16 raw bytes and a small integer. The table and its six indexes go
780 MB to 405 MB on a real 2,052,200-row catalog, which is why a fresh
install is ~0.6 GB rather than ~1.0 GB.
- `backend/explore/mbid.go` is the only place the encoding is known;
everything above it speaks dashed strings.
- `CHECK(length(mbid) = 16)` makes a stringly write fail at the insert
rather than silently returning no rows, since SQLite does not coerce
between TEXT and BLOB.
- The importer asks the artifact what encoding it carries and converts
on the way in, so the artifact already published keeps working and no
format bump is needed.
- `indexRowColumns`/`scanIndexRow` replace four copies of a 22-column
list, and `TestStoredEncodingRoundTrips` sweeps every read path.
## An album page that says how much of the album is yours
- One question, asked once: is there a file. `filePaths` is filled by a
single batched lookup when the tracklist settles, and the badge, the
Play count, the dimmed rows and every menu item read it — replacing
four claims of decreasing confidence that could show a green tick on
an album whose every action did nothing.
- Play, Play 7 of 12, or no play button at all.
- `total_tracks` on `explore_index` (~2 bytes over 400,677 release
groups) and on `audio_files` from tags that have always carried it:
a complete MBID-matched album now makes no catalog call at all, where
it used to spend the most expensive request the app makes.
- A merged cluster shows the running order the most releases agree on,
and the version list marks the release you own rather than standing a
synthetic entry in for it.
- `AlbumReleasesFailed`: a slow fetch is no longer reported as a failed
one by a 12-second timer.
- Rows not in the library are dimmed in place (with `aria-disabled`)
instead of the owned ones wearing a green tick and a legend.
## Caches and cover art get ceilings
- Only the three tiers of a cover are stored; the full-resolution copy
nothing rendered was 1,134 MB of a 1.4 GB covers directory.
- One artist portrait is downloaded and the rest are remembered as
URLs — 4.1 GB of a 5.3 GB cache was candidates no code path reads.
- `browsedArtBudget` and `httpCacheBudget` bound what an age cannot:
the same install held art for 5,770 artists in a 1,301-artist
library.
- `OrphanedArtistImagesJob` joined a bare MBID onto a sharded
directory, so it deleted the rows that were the only record of the
files it left behind. `explore.ArtistImageDir` is that layout's one
definition now.
## The autotag queue asks whether there is work
`tagging_items` was a row per album folder, not a queue, and no query
read the `tag_status` column that held the answer. The four queue
queries ask the files, which matters most where it is least visible:
`startPrefetch` was scoring every album in a tagged library against
MusicBrainz.
## Phantom playlist tracks resolve in place
An M3U8 imported before its files leaves phantom rows; they now match
by path and fall back to position, keep their place in the playlist
when resolved, and pair best-first so two phantoms cannot claim the
same file.
## Playing a track plays the list it is in
Double-click, and Play on a single row's menu, queue the list as
displayed with `startIndex` on that row — the album page and the track
list used to queue one track and discard the album around it. A
multi-row selection still plays exactly itself.

Phases 2 and 3 of plan 009, plus the parts of phase 1 that could not
land before them. Nothing in the tree imports wails/v2 any more; all
three lint and test configurations are green and `go build .` produces
a running binary.
The point of the migration is one file. backend/events/emit.go probed
ctx.Value("events") — a v2-*private* context key — to decide whether
emitting was safe, because runtime.EventsEmit called log.Fatalf on a
context without the runtime and took the process down with it. v3's
emit takes no context, so that is now application.Get() == nil. D1
held: events.Emit keeps its ctx as the WithSink test seam, and all 45
call sites and 7 test files are untouched.
The bootstrap splits into application.New + Window.NewWithOptions +
Run. Ten bound services implement ServiceStartup instead of being
handed a context by hand from OnStartup, which also stops ten
SetContext methods being exported as bindings. jobs.Registry and
explore.SearchIndex keep theirs — neither is bound, so converting them
would be churn for no binding removed.
Four things differed from the plan and are written up in it: GPU policy
moved to the per-window LinuxWindow options rather than surviving on
LinuxOptions; there is no OnStartup/OnDomReady option, so app-level
wiring hangs off ApplicationStarted; application.NewService is generic,
so FEBindings []any could not survive (the binding generator is a
static analyser and would have seen nothing); and the quit veto had to
be restructured, because v3's dialog answers on a callback rather than
returning the button, so ShouldQuit vetoes, asks, and quits again from
the callback.
Window state saving moves to a WindowClosing hook — the size has to be
read while the window still exists, and v3's OnShutdown has neither
context nor window. backend/logging is deleted rather than ported:
v3 takes a *slog.Logger directly, so the v2 logger.Logger adapter had
no caller left.
Phase 1's tail rides along, now that it can: the Makefile's wails
invocations, all 50 webkit2_41 sites, lefthook, both packaging recipes
and ci.yml's apt lists. v3 builds against GTK4 + WebKitGTK 6.0, which
Arch and ubuntu:24.04 both ship, so the tag is a deletion rather than
a translation.
Phase 4 is next and the branch is not usable until it lands: the app
builds, but frontend/wailsjs/ is v2's tree and nothing regenerates it,
so the frontend cannot reach the backend yet.

A coding agent could develop this repo's Go packages and could not
develop the application: every path to running YellowJacket ended in a
blocking GTK window, so 265 bound methods, 46 events, 33 component
directories and 13 stores had exactly one form of verification
available — `tsc --noEmit`.
The unlock is that `wails dev`'s dev server on :34115 serves the real
frontend with the real generated bindings against the same Go backend a
desktop window attaches to, so a plain Chromium under Xvfb gets a fully
functional app. Four test tiers now exist, cheapest first:
- `make ui-test` — 313 Vitest tests in a real browser in ~2 s, no app,
no backend, no display. Works because `frontend/wailsjs/` is a pure
passthrough to `window.go`/`window.runtime`, so faking just those two
globals runs the real bindings and the real store code.
- `make test` — services in-process, asserting on the payload the
frontend would receive, via a new `events.Emit` wrapper.
- `make dev-headless` + `playwright-cli` — the real app, driven
interactively, with an event bridge on `window.__yjEvents` and a
dev-only control surface at `/__test/`.
- `make e2e` — 19 of those flows frozen as Playwright specs.
`events.Emit(ctx, …)` replaces all 35 direct `runtime.EventsEmit` call
sites: wails' `getEvents` `log.Fatalf`s on any context without its
runtime, so those paths could not run under test and a background
worker could take the app down. Four packages had each hand-rolled the
same guard; nine more guarded on `ctx != nil`, which does not help.
`TestNoDirectRuntimeEmits` fails the build on a new one.
Fixtures are generated, not committed (`make testdata`), and seeds are
built by *running the app* — never by hand-writing config and DB rows,
which would be a second description of a valid YJ_HOME.
`.gitea/workflows/ci.yml` is the first workflow here that tests
anything; the other three only package, so `gitea_ci` reported only
packaging jobs and misled anyone asking whether a push was healthy.
Both jobs were prototyped to green in a bare ubuntu:24.04 container
before the YAML was written, which immediately caught `make lint`
linting three configurations that nothing builds: all three passes
omitted `webkit2_41`, so wails resolved webkit2gtk-4.0 — which Arch
still ships and Ubuntu 24.04 dropped.
Operational instructions live in `.pi/skills/yellowjacket-dev/`,
measured discoveries in `.planning/NOTES.md`, and architecture in
`CLAUDE.md` — split by tense, not by topic, because a topical split
gives every new fact two plausible homes. `make skill-check` fails a
commit if the skill cites a make target that does not exist.
Ships the fresh-start schema cleanup: rebuilt explore catalog index
pipeline (dump import, artifact fetch/build, incremental listen-count
refresh), a new download subsystem (Lidarr/Prowlarr/qBittorrent/SABnzbd/
slskd/yt-dlp providers, staging, reconciliation, wanted list), and the
supporting schema/query/store changes across backend and frontend.
Also includes two smaller follow-ups: bump the central index's
rebuild-after cadence from 90 to 180 days, and remove the Explore
"library only" online/offline toggle entirely (frontend-only, no
backend counterpart) rather than carry unused UI/state.

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.
Wails deserializes JSON numbers from JavaScript as float64, not int.
All .(int) type assertions on year, track_number, and disc_number
silently failed. Add asInt() helper, replace all assertions.
