File-watcher and metadata-extraction service for the MetaMesh ecosystem.

into Redis via the meta-core-compatible `/meta/*` API on this service.

sibling services (meta-fuse, meta-stremio) can read media without
needing the underlying bind/SMB/rclone mounts.
4. **Computes file identity**: `midhash256` in the light phase, full-file
digests (sha1, sha256, md5, sha3, crc32, btih v2) in the background

## Architecture
### Two-volume layout
### Volumes
meta-sort consumes two host-side volumes via standard bind mounts:
meta-sort needs **no shared volume**. Media lives on meta-core's
`FILES_VOLUME` and is read over meta-core's WebDAV; file paths stored in
Redis are **relative to `/files`**, which keeps storage portable across
hosts. The only mounts are its own cache (`/data/cache`), the Docker
socket (for plugin containers) and `plugins.yml`.
| Volume | Container path | Owner | Purpose |
|--------|----------------|-------|---------|
| `META_CORE_VOLUME` | `/meta-core` | meta-core writes, all services read | Leader-info file, Redis data, service registry, SSE cursor |
| `FILES_VOLUME` | `/files` | meta-sort serves over WebDAV | Watched media, plugin output, dynamic mounts |
File paths stored in Redis are **relative to `/files`**, which makes the
storage portable across hosts. See the root `CLAUDE.md` for the
authoritative volume layout description.

The protocol spec is `docs/project-architecture/beacon-v2.md` in

guarded by the meta-root's `scripts/check-mirrors.sh` — change it there in
lockstep.
The SSE cursor is persisted to `/meta-core/cursors/meta-sort-files.cursor`

that path is container-local and does not survive a container recreate.

The repo `Dockerfile` (published to `ghcr.io/worph/meta-sort` by
`.github/workflows/docker-publish.yml`) is an all-in-one image: nginx on
`:80` → Fastify on `:3000`, rclone, and a bundled `meta-core` binary
copied from `ghcr.io/worph/meta-core` and started by
`docker/supervisord.conf`. Deployments run meta-core as its own app, so
both the dev stack and the store app mount their own supervisord/nginx
configs that drop the bundled meta-core.

/**
* <meta-beacon-scan> — "what plugins are on the network?", as a card.
*
* The Scan button POSTs to the host's own discover endpoint, which probes the
* beacon v2 group (239.255.99.1:9099), waits for the replies, and classifies
* every resource matching the host's capability (transport plugins for
* meta-share, feeders for meta-gateway, enrichment plugins for meta-sort):
*
* 10 nodes on the network · 3 transport plugins · 3 already configured
*
* Each `addable` row gets an Add button that POSTs {name, url} to the host's
* existing add endpoint. Response shape: meta-feeder-sdk `beacon::ScanReport`
* (docs/project-architecture/beacon-v2.md).
*
* ⚠ MIRRORED FILE. Byte-identical copies live in meta-share, meta-gateway and
* meta-sort-ui; see `scripts/check-mirrors.sh`. Edit one → edit all.
*
* Shadow DOM for the same reason as <meta-service-menu>: the three hosts use
* incompatible token vocabularies. Style it from the host with
* --mm-scan-fg, --mm-scan-bg, --mm-scan-border, --mm-scan-accent,
* --mm-scan-ok, --mm-scan-err
*
* Attributes:
* scan-endpoint POST → ScanReport (required)
* add-endpoint POST {name, url, ...add-extra} (required)
* add-extra JSON object merged into the add body (optional)
* label what the host calls a capable resource, plural
* (default "plugins")
*
* Events (bubbling, composed):
* beacon-added detail = { candidate, response }, after a successful Add
