Five tasks, four delegated to agents on disjoint files and one on the critical
path. Board and verification log: ~/.opencode/plan/vellum-beta-tasks.md
T1 Async scans (coordinator)
- migration 0007 adds ref_id + result to jobs, indexed by (kind, ref_id, id),
so a job can be found by what it operates on and can report back.
- jobs: EnqueueRef, JobID(ctx) so a handler can attach a result, SetResult.
- POST /libraries/{id}/scan now enqueues and returns 202; a real library takes
longer than any request timeout, and a hanging request looks like a broken
server. GET /libraries/{id}/scan/status reports the latest run.
- Libraries.svelte polls and shows "Scanning…" instead of freezing.
T2 Admin CLI (agent)
- internal/cli: `user add|passwd|list`, `backup <path>` via VACUUM INTO, with
tests. Wired into main.go, which the coordinator kept.
T3 Deploy (agent)
- compose.yml now mounts all six media kinds read-only with :z and carries the
metadata env keys. DEPLOY.md covers volumes, SELinux, admin bootstrap, TLS,
backup and upgrade.
T4 Pagination (agent)
- GET /items takes offset and returns total; Browse loads 60 at a time with
"Load more" and "Showing X of Y" instead of silently truncating at 300.
T5 Password change UI (agent)
- A Password section in Settings with validation, busy and success states.
Verified end to end: scan returns 202 in 0.7 ms and polls to done; the CLI
created a user, changed a password, and produced a complete 240 KB backup while
the server ran; pagination reports total 8 and pages correctly; compose parses
with every mount :z. go vet and 14 test packages pass; svelte-check 0/0.
- photos: generates a downscaled JPEG thumbnail per image, because serving a
folder of 12-megapixel originals to a grid is unusable on a TV box. Uses
CatmullRom scaling via golang.org/x/image; decodes jpeg/png/gif/webp.
- an undecodable format returns no thumbnail rather than an error, so the grid
falls back to a placeholder.
- images already smaller than the 512px ceiling are passed through untouched.
- library items endpoint now returns library_id, which the viewer needs to
find its siblings for navigation.
- web: PhotoViewer with keyboard and button navigation within the library.
Verified: 900x1200 PNG thumbnailed to a 512-long-edge JPEG and served;
unit tests assert exact dimensions, aspect preservation, and that non-images
produce no thumbnail without erroring.
- library: CRUD with root-path resolution (absolute, symlink-free, must be
readable). A library name is unique; the root is validated at creation.
- registry: media types declare their extensions; the core never imports a
module. RegisterType is the extension point.
- scanner: walks a root, reconciles media_items/media_files in one
transaction, skips unchanged files by size+mtime, and marks vanished files
missing rather than deleting them (progress is the one thing here that
cannot be regenerated). A single unreadable file never fails a scan.
- migration 0002: `missing` flags on items and files, plus indexes.
- endpoints: media-types, library list/get/create/delete, per-library items,
and scan. Library reads go through the same grant chokepoint as everything
else; an unauthorised library 404s rather than 403s so its existence is not
leaked.
