Work on the Android app — the thin WebView wrapper in `android/`. Use this whenever a task touches the Kotlin sources, the Gradle build, the WebView shell, the native settings screen, LMS server auto-discovery, the JS↔native bridge, app strings/i18n, or the Android CI/lint. Covers the "shell only, UI lives on the web" principle, the debug/release signing split, the static versioning F-Droid needs, and the min/target SDKs, so changes fit the wrapper.

The Android app is a thin native shell: the whole UI is the web dashboard served by the Flask app, loaded in a full-screen WebView. Same principle as lms-material-app. Don't rebuild dashboard UI natively — if a feature belongs on screen, it belongs in the web page; the app only provides shell concerns (window, settings, discovery, a native bridge).
Everything lives under android/. Package com.werdeil.lyriondashboard, Kotlin, Gradle KTS, minSdk = 26 (Android 8.0), targetSdk = 35, compileSdk = 37, Java/JVM 17.

CI is .github/workflows/android.yml: on every push touching android/** it runs lintDebug then assembleDebug and uploads the debug APK as an artifact. The release APK is built and attached only when a GitHub release is published (see the release skill).
app/debug.keystore (standard debug credentials) on purpose — so every ephemeral CI runner signs with the same key and Android will update the app over a previous install instead of refusing. Debug builds also use an applicationIdSuffix = ".debug" and a distinct label, so they install side by side with the release app.ANDROID_KEYSTORE_PATH and friends) so the release keystore is never committed. Without them a local release build stays unsigned, which is also what F-Droid wants — but the release workflow refuses to publish an unsigned APK: it validates the keystore up front and runs apksigner verify on the result (see the release skill).versionName and versionCode in app/build.gradle.kts are static literals, committed, because F-Droid builds from the tagged source and parses them from that file. versionCode packs the semver as X*10000 + Y*100 + Z. Don't compute them at build time. Bumping is the Release workflow's job — see the release skill.
MainActivity injects a window.LyrionApp object into the page. The web JS detects it, adds body.in-app, and wires the header menu to bridge.openMenu() / openSettings() and the card's pull-to-refresh gesture to bridge.reload() (see the frontend skill). If you add a native capability the page should call, expose it as a method on that bridge and guard the page-side use behind the object's presence, matching the existing pattern.
ServerDiscovery finds the Lyrion server via UDP broadcast on port 3483 (the standard LMS discovery protocol) and suggests http://<host>:1111 (assumes the dashboard runs on the same host). Caveat baked into the UX: discovery can't cross a VPN tunnel, so the settings screen lets the user enter the URL manually. Cleartext HTTP is allowed (LAN-only app).
App strings are bilingual like the web app: res/values/strings.xml (EN) and res/values-fr/strings.xml (FR) must carry the same keys. Store-listing texts live under fastlane/metadata/android/{en-US,fr-FR}/. Add a new string to both locales — never one only. The same tree holds images/icon.png, the 512x512 render of static/favicon.svg that F-Droid shows on the app page: its indexer cannot render the adaptive-icon XML, so without that bitmap the listing has no icon. full_description.txt is never hard-wrapped — F-Droid clients keep every newline, so a paragraph wrapped at 70 columns renders ragged; one paragraph (and one bullet) is one line, however long.

Add or modify a Flask endpoint in the Lyrion Dashboard. Use this whenever a task adds a new URL/route, a JSON API endpoint, or a page — anything that registers a handler in `routes/`. Covers the repo's route → service → test layering, input validation, caching headers, security headers, i18n wiring, and the exact test pattern, so a new endpoint matches how `routes/` already works instead of reinventing the structure.

Work on album artwork — reading an image's dimensions, and embedding a folder's cover file into the tags of its tracks. Use this whenever a task touches `services/artwork.py`, the cover half of `services/tags.py`, or `scripts/embed_covers.py` / `embed_covers_cron.sh`. Covers why Lyrion shows the embedded artwork and never the folder file, how covers are compared, why images are never re-encoded, and what embedding costs in rewritten files.

Read data from Lyrion's SQLite databases — library stats, stored lyrics, album covers, recent plays. Use this whenever a task queries `library.db` or `persist.db`, adds or changes a statistic, or touches `services/database.py`. Covers the read-only connection model (RO open + `ATTACH persist.db`), the key tables, the `play_counts` view over the Alternative Play Count plugin, the single-flight stats cache, and why the app must never write to these DBs. Reach for it before writing any SQL against the Lyrion databases.

Work on the dashboard's frontend — the vanilla JS/CSS page with no framework or bundler. Use this whenever a task touches `static/nowplaying.js`, `static/style.css`, the Jinja templates (`templates/nowplaying.html`, `_icons.html`), the accent-color tinting, the karaoke lyrics sync, the now-playing poll, or the empty-state mosaic / recent-plays pile. Covers how the page is wired, how it reads i18n and data from the server, the ESLint gate, and the Android bridge, so changes match the existing patterns.

Add, change, or translate user-facing text in the Lyrion Dashboard, which ships bilingual FR/EN. Use this whenever a task introduces a new visible string (a label, tooltip, aria-label, empty state, stat name), changes wording, or touches the README or a `docs/` page — so every string lands in both languages and the EN/FR documentation pairs stay in sync. Covers `i18n.py`, how templates and JS consume translations, and the parity rule.

Work on lyrics — the web fallback (LRCLIB, Musixmatch, NetEase, Genius), the in-memory cache, verification, and embedding lyrics into audio file tags. Use this whenever a task touches `services/lyrics.py`, `services/tags.py`, the `/lyrics.json` route, or `scripts/embed_lyrics.py` / `embed_lyrics_cron.sh` — adding or fixing a provider, changing caching/verification, or the batch tagger. Covers the provider contract, the synced-vs-plain rule, the read-only cache, and why writes only ever store plain text.
