- comics: reads pages straight out of the archive on demand. No extraction
pass, so a 200-page CBZ is not materialised for a reader who views three
pages. Pages are read into memory and served via http.ServeContent, which
gives Range for free.
- natural page ordering: page2 sorts before page10. Lexical ordering shuffles
a numbered archive, which is the difference between a readable book and a
scrambled one.
- skips __MACOSX and dotfiles; rejects archives with no images.
- cover is the first page.
- media.Item gained ModTime (from the backing file) so page responses carry a
Last-Modified and support conditional GETs.
- web: ComicReader with a bounded prefetch window (two pages each way), page
jump, keyboard nav, and progress stored as a page number.
Verified: 3-page CBZ served in natural order, out-of-range 404, cover from
page 1, progress round-trip. svelte-check 0/0.
README status table, full env var reference including admin bootstrap and
cookie security, package layout, and build commands. Plan doc updated with a
progress log, the deviations from plan and why, and the gaps carried forward.
The frontend the app needs to be usable at all.
- web/: Svelte 5 + Vite + TypeScript SPA. Login, app shell with per-type nav,
library list/create/scan/delete, item grid with covers, admin user
management, and an epub.js reader that syncs progress.
- Reader resumes by spine index — an integer — which is why the polymorphic
progress table needs no text column.
- Session state uses classic stores in a plain .ts module rather than runes in
a .svelte.ts module, avoiding special module resolution.
- Embedding: web/embed.go embeds web/dist. A committed .gitkeep keeps the
directive valid before the frontend is built, so `go build ./...` never
fails. Unknown non-API paths serve index.html for client routes; /api/* and
/healthz always return JSON and never fall back to HTML.
- Dockerfile builds the UI in a node stage and overlays dist into the Go stage.
- pnpm 12 needs allowBuilds in pnpm-workspace.yaml; esbuild approved, the two
unused transitive scripts explicitly denied so install exits 0.
svelte-check: 0 errors, 0 warnings. Verified served: SPA shell at /, route
fallback, hashed asset, and JSON 404 on /api/*.
- stream: serving goes through http.ServeContent, so Range/If-Range/
If-Modified-Since are correct for every media type by construction
- progress: the polymorphic store. One row per user/item/file; the PK includes
the file so multi-track audiobooks resume per track later. Finished is
inferred when position reaches duration.
- media: generic item endpoints (detail, file, cover, progress, recent). Every
one routes through auth.CanAccessLibrary; an unauthorised item 404s.
- covers: a per-kind extractor registry. Extraction is lazy and recorded in
the assets table. A missing cover is a placeholder, never a 500.
- modules/ebooks: EPUB parsing (container.xml -> OPF -> metadata, spine, cover
with three fallback strategies), cover extraction to /config, and lazy
metadata parsing so parser fixes need no rescan.
Verified against a generated EPUB: title/2 authors/language/publisher/spine,
cover served as PNG, range request returned 206 with correct Content-Range,
progress round-tripped.
- 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.
Multi-user from the first migration, as planned.
- auth: argon2id password hashing (PHC encoded, parameters travel with the
hash), opaque session tokens stored only as SHA-256, login rate limiting,
and account enumeration resistance (unknown user hashes anyway)
- sessions: cookie or Bearer auth, HttpOnly + SameSite=Lax, revocation on
password change
- grants: library_grants is the single access-control chokepoint. Admins see
every library; everyone else sees exactly their can_read grants
- bootstrap: VELLUM_ADMIN_USER/PASSWORD create the first admin only on an
empty database. No default password is ever invented.
- httpapi: mounts modules on a shared mux, session middleware innermost
- httpx: shared JSON helpers, strict body decoding
Gate: two users see different libraries. Tests cover that, plus session
expiry, token-at-rest, grant upsert, and the full login/me/logout flow.
Bootstraps Vellum as a single Go binary with one SQLite database.
- core: env-driven config, slog logging, SQLite (WAL) with pooled pragmas,
embedded migration runner keyed on PRAGMA user_version
- migrations/0001_core.sql: identity, media, user state, infra. Media items
are global; all per-user state (progress, favorites, grants) is a join.
One polymorphic progress table covers every media kind.
- httpapi: request-ID, structured request logging, panic recovery, JSON
endpoints for /healthz and /api/v1/version
- multi-arch Dockerfile (pure-Go SQLite, CGO_ENABLED=0) with an entrypoint
that honours PUID/PGID like the rest of the self-hosted stack
- tests for migration idempotency, FK enforcement, WAL, config, middleware
Media does not exist yet. Nothing is exposed beyond health and version.
