- 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.
- 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.
