+# Audiobookshelf
+
+Audiobookshelf (ABS) serves the [[Entropy Volume]] audiobook library to browsers
+and phones: it scans `/mnt/entropy/Audiobooks`, keeps its own SQLite library with
+per-listener playback positions, and streams the audio. It is **not** a media
+server — it shares nothing with [[Plex]] or [[Jellyfin]] and owns no files on the
+array.
+
+**Host:** Dankserver — **Unit:** `audiobookshelf.service` (rootless Quadlet, user
+manager) — **Internal-only:** LAN address, no vhost, no DNS name.
+
+## Shape
+
+| Item | Value |
+|------|-------|
+| Unit file | `dankserver/audiobookshelf/quadlet/audiobookshelf.container` (the authority for every number here) |
+| Image | `ghcr.io/advplyr/audiobookshelf` pinned by **amd64 manifest digest** — see Laws |
+| Port | `PublishPort=8000:8000` — web UI and API on the same port |
+| Network | `pasta` (standalone; publishes nothing to other containers) |
+| Audio bind | `/mnt/entropy/Audiobooks:/audiobooks:ro` — read-only, by design |
+| State | `/home/dank/Containers/audiobookshelf/config` → `/config`, `…/metadata` → `/metadata` (both NVMe) |
+| Mount gate | `ExecStartPre=…/wait-for-mount.sh /mnt/entropy` |
+| Health | `wget` against `/healthcheck` inside the container, 30 s / 3 retries |
+| I/O share | `IOWeight=10` — a scan loses the array to every other tenant |
+| Self-healing | `Restart=always`, `RestartSec=5`, `WantedBy=default.target` |
+| Deploy | `./scripts/deploy.sh dankserver --service audiobookshelf` |
+| Handler | `deploy_audiobookshelf` in `scripts/deploy-remote.sh` |
+
+## First run
+
+1. Open `http://192.168.0.235:8000` **from the LAN**. ABS accepts the initial
+   account creation only from a local-network address; a remote address gets a
+   refusal, not a form.
+2. Create the owner account, then add one **Audi Book** library with folder
+   `/audiobooks`. The path is the in-container name of the read-only bind.
+3. The first scan reads the whole tree once. It runs in the background — the
+   deploy gate is already green by then, and `IOWeight=10` keeps it off the
+   critical path.
+
+Nothing in this repo holds an ABS credential: the account is created in the
+browser and lives in the `config` bind on the SSD.
+
+## Laws
+
+- **The audio bind stays `:ro`.** ABS writes nothing that belongs beside the
+  audio: its library, covers, progress and sidecar metadata all land in
+  `/metadata` on the SSD. A writable bind would put stray writes on the spindle
+  and hand the array to a service with no reason to hold it. If per-book
+  `.opf`/`.nfo` sidecars on disk are ever wanted, the rollback is one line —
+  point the audio bind at the [[Media Metadata View]] the media servers already
+  use — but that view's upper layer exists for those two servers' sidecars, so a
+  third writer needs a reason first ([[Media Metadata View]]).
+- **Do not bind the raw array without the mount gate.** In a rootless unit
+  `ConditionPathIsMountPoint=` is fail-*dead* and `RequiresMountsFor=` is inert,
+  so a missing array does not stop the start: podman invents an empty directory,
+  ABS indexes it, and an empty library becomes recorded truth. `wait-for-mount.sh`
+  is the only gate that works here — same law the media servers obey
+  ([[Quadlet Lifecycle]]).
+- **The `HealthCmd` must use `wget`.** The image is Alpine and ships `wget`, not
+  `curl`; a `curl` health command reads a perfectly healthy server as unhealthy
+  and `Restart=always` turns that into a loop.
+- **The image pin is the amd64 manifest digest, not the index digest.**
+  `podman inspect` reports the platform manifest (`RepoDigests[0]`) for what was
+  pulled, which differs from the manifest-list digest `latest` points at. Pin the
+  one this host runs. `latest` is newer than the newest version tag: upstream
+  stopped publishing version tags after `2.19.0` while `latest` kept moving, so
+  "highest version tag" is stale here — read the index, don't guess from tags.
+- **`IOWeight=10` is inert without the host drop-ins.** `dankserver/host/systemd/`
+  carries `user.slice.d/io-accounting.conf` and the `user@1000` delegate, and the
+  deployer installs both; without them systemd silently drops the weight
+  ([[Quadlet Lifecycle]]).
+- **No `systemctl --user enable`.** Generated Quadlet units cannot be enabled on
+  this host; `WantedBy=default.target` in the unit file is what carries the
+  service across a reboot ([[Quadlet Lifecycle]]).
+- **LAN-only until Frank says otherwise.** `0.0.0.0:8000` with no reverse proxy
+  in front. Any public vhost requires the Anubis + Authentik chain first, and the
+  outpost proxy provider has to exist before the vhost flips (external exposure
+  policy in `AGENTS.md`).
+
+## Verification
+
+`./tests/run.sh` covers this unit through `tests/dankserver_quadlet.bats`
+(boot persistence, the SSD state roots, the `:ro` array bind, the mount gate, the
+`wget` health check) and `tests/media_overlay.bats` (only [[Plex]] and
+[[Jellyfin]] may reference the metadata view).
