Two fixes in one commit because they're entangled — the systemVariant work would have been theater otherwise. ## The wire-format bug /api/library/sync was emitting PascalCase JSON for artist / album / track / playlist upserts (raw json.Marshal of sqlc-generated structs with no JSON tags — sqlc.yaml: emit_json_tags=false). Flutter's sync_controller _*FromJson reads snake_case keys, so all metadata sync rows landed in drift with empty strings / zero ints. The like_track / like_album / like_artist / playlist_track entities work because they're hand-built `map[string]string` payloads with snake_case keys — they sidestepped the bug. The 4 raw-marshal entities did not. Existing sync test caught zero of this — it asserts on len(upserts) not field shape. Fix: server-side view structs in library_sync_views.go with proper JSON tags + pgtype-flattening (UUID → 8-4-4-4-12 hex string, Date → "2006-01-02"). Mirrors the playlistRowView pattern from /api/playlists. New library_sync_views_test.go pins the wire keys so future field-name drift breaks loud. ## systemVariant column (closes #357 plan C v1 limitation) playlistSyncView now carries `system_variant` server → wire. Flutter drift schema bumped from 1 → 2 with onUpgrade adding the `systemVariant TEXT NULL` column to cached_playlists. Cursor reset to 0 in the migration so existing rows refresh with the new field on the next sync. playlistsListProvider now filters locally by systemVariant: - kind='user' → systemVariant IS NULL (the add-to-playlist sheet's intent) - kind='system' → systemVariant IS NOT NULL - kind='all' → no filter Closes the documented v1 limitation where the add-to-playlist sheet showed system playlists alongside user-created ones.

Minstrel mobile client
Flutter (iOS + Android) sibling of the SvelteKit web SPA. v1 first slice ships: scaffold, auth, library browse (home / artist / album), likes, player with background audio + lock-screen controls.
Setup
cd flutter_client
flutter pub get
./tool/sync_shared.sh # copy tokens / error-copy / placeholders from ../web
dart run tool/gen_tokens.dart # regen lib/theme/tokens.dart from shared/fabledsword.tokens.json
flutter run
sync_shared.sh is idempotent. CI runs it on every build; rerun locally
whenever web/src/lib/styles/tokens.json,
web/src/lib/styles/error-copy.json, or
web/static/placeholders/album-fallback.svg changes.
Project layout
See docs/superpowers/specs/2026-05-02-flutter-mobile-foundation-design.md
section 3. Briefly:
lib/api/— dio client, ApiError, error-copy loader, per-surface endpoints.lib/auth/— server URL screen, login screen, AuthController + secure storage.lib/library/— home, artist detail, album detail, providers, widgets.lib/likes/— LikeButton + optimistic toggle controller.lib/player/— audio handler, player provider, mini PlayerBar, NowPlaying.lib/theme/— FabledSword token Dart class (generated), ThemeExtension, ThemeData.lib/shared/— routing (go_router shell), version gate, connection error banner.
shared/fabledsword.tokens.json and assets/error-copy.json are
synced from web/. Don't edit them directly — edit web/src/lib/styles/
and re-run ./tool/sync_shared.sh.
Architecture
- State: Riverpod 2 (
AsyncValue,AsyncNotifier, family providers). - HTTP: dio 5 with a Bearer-auth interceptor; 401 clears the session and the router redirects to login.
- Audio: just_audio wrapped by audio_service for background playback + lock-screen / notification controls.
- Auth: Bearer tokens in flutter_secure_storage. Server already
supports both cookie (web SPA) and Bearer (
internal/auth/session.go). - Routing: go_router with a ShellRoute so the PlayerBar persists
across navigation. Cold launch flow: no server-url →
/server-url, url set / no token →/login, token present →/home.
CI
.forgejo/workflows/flutter.yml runs on push to dev/main, tag pushes,
PR to main, and manual dispatch — path-filtered to flutter_client/**
plus the shared web inputs. Steps: sync, analyze, test, build APK.
Debug APKs upload as artifacts; release APKs attach to the Forgejo
release on tag.
Versioning
pubspec.yaml version mirrors the server tag (e.g. server v0.1.0
→ Flutter 0.1.0+1). The server's /healthz returns
min_client_version; old clients show an Update Required modal and
refuse to operate. Bump internal/server/version.go MinClientVersion
when a server-side change requires a paired client update.
Distribution
- Android: APK on the Forgejo release page. No Play Store for v1.
- iOS: TestFlight on tag (manual upload v1, automate later).
Out-of-scope for slice 1
Search, discover, requests, settings beyond server URL, admin, listening history, playlists, offline cache (#357). Those land in subsequent slices with their own brainstorm/spec/plan cycles. Per the operator's M7 ordering decision (2026-05-02), slice 2+ pauses to ship the missing web features first (#352 playlists, #362 theme toggle, #363 queue UI, #364 listening history, etc.) before mirroring on Flutter.
