Server half of the active-sessions surface. Web UI follows. The operator wants this specifically to notice a compromised account, which sets the bar: the addresses have to be trustworthy, or the feature is worse than absent because it looks like evidence. Migration 0052 adds created_ip + last_ip. Two columns, not one, and the pair is the signal: a session issued at home and now being used from elsewhere is the shape of a stolen token, and neither column alone can show that. Typed text, matching the user_agent column beside it — these are displayed, never queried by subnet, and inet round-trips through pgx as a netip.Prefix that renders "1.2.3.4/32". The rest of the schema was already waiting. Migration 0004 anticipated this exactly: "last_seen_at enables an 'active sessions' UI later (not wired in this plan) without schema churn." last_seen_at is live data — the auth middleware already touches it per request — so last_ip rides that same UPDATE for free. Getting the address right is the substance here. Nothing extracted a client IP anywhere before, and both obvious approaches are wrong: - RemoteAddr alone shows the reverse proxy on every session, which is the normal self-hosted deployment. Noise shaped like data. - Trusting X-Forwarded-For lets any client choose what its victim sees. A security surface an attacker can write to is worse than none. So auth.ClientIP trusts the header only when the request actually arrived from a proxy range. Public RemoteAddr means a direct connection, so XFF is attacker-controlled and ignored outright. Private RemoteAddr means we walk XFF right-to-left — proxies append, so the right end is what our own infrastructure wrote — and take the first non-proxy address. A forged XFF only prepends to the left end, which that walk never reaches. Unit-tested, including both spoofing shapes. Fails closed on a public-addressed proxy (separate host, CDN): we report the proxy rather than trusting a forgeable header. Documented at the function. Endpoints, all scoped by user_id per rule #47: GET /api/me/sessions → list, flagging the current row DELETE /api/me/sessions/{id} → 204, or 404 if not yours POST /api/me/sessions/logout-others → {"revoked": n} Keyed on session id alone, any household member could revoke another's session by guessing a uuid, so the delete carries user_id in its WHERE and :execrows distinguishes "not yours" (404) from a false 204. There's a test that asserts the row actually survives, not merely that we returned 404. The middleware now also puts the session id in context. logout-others is defined by exclusion, and without knowing which session is ours the safe-looking action deletes everything including the caller's — so it refuses rather than guesses when the id is absent, and that refusal is tested for non-deletion too. audit_log.action is plain text with no CHECK, so the two new actions need no migration (rule #36 checked, not assumed). Codegen is real sqlc 1.31.1 via the container in `make generate` — docker is present on this workstation even though Go and sqlc aren't — rather than the hand-written .sql.go shortcut used in milestone #268.
Minstrel
A self-hosted music server that thinks for you. Smart shuffle, contextual likes, ListenBrainz-aware radio, and Lidarr automation — server-side, so every client (web, mobile, Subsonic third-party) gets the same intelligence.
State and intelligence belong on the server, not the client.
Highlights
- OpenSubsonic-compatible. Existing Subsonic clients (DSub, Symfonium, play:Sub, etc.) connect with no special configuration.
- Server-side smart shuffle. Track-similarity vectors, dual-like model (general + contextual), and session memory keep mixes coherent across devices.
- ListenBrainz radio. Session-aware "more like this" pulls from ListenBrainz similarity data, not a static genre tag.
- Lidarr integration. Triggered scans, request-driven album imports, and a quarantine flow when something doesn't fit — against a Lidarr instance you run and configure. Optional, and off until you supply a URL and API key.
- Built-in web SPA. Full-feature library, search, queue, playlists, and admin — no separate frontend container to deploy.
- Native Android client, shipped with the server. The signed APK is bundled into every image and attached to each release — sideload it once, then the app self-updates straight from your own server (no app store, no separate download to track).
Scope and responsible use
Minstrel serves music you already have. It is a library server: it indexes files on disk you point it at, and streams them to your own clients. It does not source, search for, or acquire content, and it has no opinion about where your files came from.
Concretely, Minstrel ships no indexers, no trackers, no torrent / Usenet / NZB client, and no DRM circumvention of any kind. There is nothing to point at a content source because Minstrel has no such subsystem.
The Lidarr integration is optional and inert until you configure it. You supply the URL and API key of a Lidarr instance you are already running; Minstrel then calls that instance's API to trigger scans, submit album requests, and reconcile imports. Minstrel neither bundles nor installs Lidarr, and configures no indexers on your behalf — Lidarr ships with none either, and any it uses are ones you added yourself.
What you put in your library, and what sources you configure in your own Lidarr, are your responsibility. Copyright law applies to your collection the same way it applies to any other software that plays a file. Please respect it, and respect the terms of any service you connect.
Minstrel is not affiliated with or endorsed by Lidarr, ListenBrainz, MusicBrainz, or Subsonic.

First run
With the stack up, a handful of in-app steps get you to a working library. Use your own host in place of localhost if you're reaching the server over a LAN/VPN address (plain http:// is fine — no TLS required).
1. Create your admin account. Visit http://localhost:4533/register. The first account on a fresh instance is automatically the administrator; later users join through the same form or an invite token (step 5).
2. Let the first library scan finish. scan_on_startup is on by default, so Minstrel walks your mounted library on boot and imports artists, albums, and tracks — no button to press. Watch progress (and re-scan any time) on the Admin page (/admin); the scan runs in stages and is incremental, so later restarts only pick up what changed.
3. (Optional) Name the instance and wire up integrations. In admin Settings → Integrations (/admin/integrations), add a ListenBrainz token (scrobbling + similarity radio) and/or a Lidarr URL + API key (the request flow). These live in the UI and apply without a restart; the display name can also be set via MINSTREL_BRANDING_APP_NAME.
4. Install the Android app. Open Settings (/settings) and use the Install the Android app card to download the APK that ships inside this server image, then sign in with the same account. From then on the app self-updates straight from your server.
5. Invite the rest of the household. From admin Users (/admin/users), generate an invite token (or enable open registration). Each person gets their own account, so likes, play history, and recommendations stay per-user.
For the full configuration surface, see config.example.yaml.
Configuration
Most operators only need the env vars in the quickstart above. A few extras worth knowing:
MINSTREL_BRANDING_APP_NAME— rename the instance ("Family Jukebox", "Office Music"). Surfaces in the header, browser tab, and OG share previews.MINSTREL_STORAGE_DATA_DIR— where generated artefacts (playlist cover collages, artist art, caches) are written. The container image sets this to/app/data, which is why the quickstart mounts theminstrel-datavolume there.MINSTREL_LIBRARY_SCAN_PATHS— colon-separated list of music library roots to scan. Supports multiple roots (/music:/podcasts).
ListenBrainz integration (per-user scrobble + similarity tokens) and Lidarr integration (URL + API key) are configured through the admin Settings UI rather than env vars or yaml — per Minstrel's "config in UI" rule, integration settings live where operators can edit them without restarting.
Most operational keys have a MINSTREL_<SECTION>_<FIELD> env override. Recommendation and events tuning are yaml-only. See config.example.yaml for the authoritative surface.
Updating
Image tags (git.fabledsword.com/bvandeusen/minstrel:<tag>):
:latest— the newest blessed image. Moves on everymainpush and every release. Recommended for most operators.:vYYYY.MM.DD— immutable per-day release tags. Pin one of these for a deployment you don't want moving under you. (Per-day CalVer — no trailing patch digit; a same-day re-cut moves the tag forward.):main— the rolling post-merge tip. Same image as:latestat push time; choose it if you want to trackmainexplicitly rather than the release line.
Every :latest and every :vYYYY.MM.DD bundles the current signed Android APK, so the in-app update channel is always live. Database migrations run automatically at startup; rollbacks require restoring a Postgres dump.
Specs
Authoritative scope lives under docs/:
- Server spec — current implementation focus.
- Client spec — Flutter companion app.
Development
Two concurrent dev processes:
- Backend:
docker compose up— Postgres + Minstrel on:4533. - Frontend:
cd web && npm install && npm run dev— Vite dev server on:5173with HMR. The Vite server proxies/api/*and/rest/*to:4533so session cookies work.
Testing
- Unit + race (no DB):
make test-short. - Full suite incl. integration tests:
make test-integration. This runs against a dedicatedminstrel_testdatabase so a test run never truncates your devminstreldata (admin user, library, likes). It brings up the compose Postgres and creates the test DB if missing. - CI runs both: a fast
go test -short -racegate plus an integration job with its own ephemeral Postgres (.gitea/workflows/test-go.yml).
Production build
docker build -t minstrel . runs the SvelteKit build inside a node stage, copies the output into the golang stage, and //go:embeds it into the final binary. The container serves the SPA from / alongside the API surfaces; no separate static-file server is required.
Branches
- Day-to-day work happens on
dev(or feature branches merged intodev). mainis protected — changes land via PR fromdev.- Releases are cut by tagging
v*offmain; the release workflow builds and pushes the container image to the Gitea registry.
Task and milestone tracking: Fable (Minstrel project, id 12).
