Marks (ratings/color labels) were stored without a user column — every
user saw every other user's marks. Labels and subjects from PhotoPrism's
global endpoints leaked across users because those endpoints ignore
BasePath ACL.
Sidecar:
- Add UserName as composite primary key on Mark (photo_uid, user_name)
- Replace validateSession with resolveSession that fetches the user
identity from PhotoPrism's session endpoint
- Filter all mark queries by user_name
Frontend:
- Filter listLabels/listSubjects through a BasePath-aware existence
check — each label/subject is kept only if the user has at least one
matching photo (single count=1 probe per item, batched at concurrency 8)
- Skip filtering for admin users with empty BasePath (single-user compat)
Also documents USER_BASEPATHS in .env.example — the env var that drives
per-user library isolation via PhotoPrism's auth_users.base_path.

Replace the Node prototype (server.mjs) with the stack the merge plan
calls for: Go 1.25, Gin for routing, GORM + MariaDB for persistence.
Same wire contract on /api/sidecar/* so the SvelteKit client doesn't
change.
- Marks move from a JSON file on disk to mule_sidecar.marks (auto-
migrated by GORM on first boot). The Node prototype's marks.json
was dev-only; not migrated.
- Folder/rename/heap-convert/duplicates handlers reproduce the
prototype's behaviour, including the path-traversal defence
(resolveUnderRoot + EvalSymlinks), the size-bucket prefilter for
the duplicate hasher, and the background reindex fire-and-forget
pattern.
- Auth model unchanged: requireSession middleware proxies the
caller's X-Auth-Token to PhotoPrism's /api/v1/photos?count=1
before any destructive op.
- Expose pp-mariadb on 127.0.0.1:3306 in docker-compose so the
host Go process can reach mule_sidecar.* without joining the
container network.
- Archive the Node prototype under sidecar/legacy/server.mjs for
one cycle as reference.
