Real-world sources publish multiple chapters at the same number:
different scanlators ("Ch.52 from bloomingdale" + "Ch.52 from mina"),
translator notices and farewells, alt-translations. The (manga_id,
number) UNIQUE constraint from 0001 silently collapsed all of those
into a single row via the upsert path in repo::crawler. Migration 0013
drops the constraint; sync_manga_chapters now plain-INSERTs each
SourceChapterRef so every parsed chapter survives as its own row.
Identity moves from the (manga_id, number) tuple to the chapter UUID:
- `GET /api/v1/mangas/:manga_id/chapters/:chapter_id` (replaces :number)
- `GET /api/v1/mangas/:manga_id/chapters/:chapter_id/pages`
- `repo::chapter::find_by_id_in_manga` (replaces find_by_manga_and_number)
- Frontend reader route renamed to `/manga/[id]/chapter/[chapter_id]`
- Chapter links throughout (manga page list, continue-reading CTA,
reader prev/next, history rows, bookmark cards) use chapter.id
- API clients getChapter/getChapterPages take a chapter id string
read_progress + bookmarks already FK chapter_id; they only enrich with
chapter_number for display, which is preserved.

Backend:
- Migration 0004_bookmarks_unique.sql adds a partial unique index on
(user_id, manga_id) WHERE chapter_id IS NULL. The 0001 UNIQUE
constraint over (user_id, manga_id, chapter_id) doesn't block dupes
when chapter_id is NULL under Postgres's default NULLS DISTINCT, so a
user could otherwise bookmark the same manga twice at the manga
level. Chapter-level dupes are still caught by the 0001 constraint.
- repo::bookmark with create / list_for_user / find_owner / delete.
create catches the 23505 unique violation and surfaces it as
AppError::Conflict so handlers return a clean 409.
- POST /api/v1/bookmarks { manga_id, chapter_id?, page? } — CurrentUser
required. Pre-validates the manga exists (404 if not) and, when
chapter_id is supplied, that the chapter belongs to that manga (also
404), so FK violations can't bubble up as 500s.
- DELETE /api/v1/bookmarks/{id} — owner-only. 404 if unknown, 403 if it
exists for another user, 204 on success. Idempotent: deleting an
already-deleted bookmark is 404, not 500.
- GET /api/v1/me/bookmarks — paged envelope, sorted by created_at DESC,
scoped to the current user so the URL itself can't be used to peek at
someone else's bookmarks.
Integration coverage in tests/api_bookmarks.rs (9 cases): create+list
returns only own; duplicate manga-level bookmark → 409; unknown manga
→ 404; unauthenticated POST → 401; user A cannot delete user B's
bookmark (403); unknown delete → 404; double-delete → 404, not 500;
/me/bookmarks requires auth; paged envelope shape on empty list.
Frontend:
- lib/api/bookmarks.ts with createBookmark / deleteBookmark /
listMyBookmarks. listMyBookmarksOrEmpty wraps the 401 case so pages
can render anonymously without try/catch boilerplate.
- /manga/[id] overview: pre-loads the user's bookmark list in its load
function and renders either:
- "★ Bookmarked" / "☆ Bookmark" toggle with aria-pressed when authed;
click POSTs or DELETEs and mutates a local working copy of the
bookmark list (optimistic UI without re-fetching);
- or a "Sign in to bookmark" link for anonymous users.
- /bookmarks page lists the current user's bookmarks (chapter-level
bookmarks link into the reader, manga-level back to the overview).
Anonymous users see a sign-in prompt instead of a 401 page.
E2E in e2e/bookmarks.spec.ts (3 cases): authed toggle round-trip
(bookmark, see in /bookmarks list, unbookmark); anonymous user gets the
sign-in CTA on the overview; anonymous /bookmarks shows the sign-in
prompt. Existing reader.spec.ts updated for the new
bookmark-signin/toggle test IDs.
Lockstep version bump to 0.7.0.

Backend:
- Migration 0003_pages.sql adds a `pages` table (id, chapter_id,
page_number, storage_key, content_type) with a unique (chapter_id,
page_number). New table because chapter pages can have different MIME
types per page; reconstructing keys from a single template would
break the moment a chapter mixes png and jpg pages.
- `domain::Page` + `repo::page` (create + list_for_chapter).
- The chapter upload handler now inserts one page row per part as it
writes the bytes to storage.
- GET /api/v1/mangas/{id}/chapters/{n}/pages returns `{pages: [...]}`
with the storage_key clients need to construct image URLs. 404 if
the manga or chapter doesn't exist; reads are public.
Storage trait grows `get_stream(&str) -> StreamingFile` returning a
`Pin<Box<dyn Stream<Item = io::Result<Bytes>> + Send>>` + size. The
local backend implements via `tokio::fs::File` + `tokio_util::io::
ReaderStream` with a 64 KiB chunk size. GET /api/v1/files/*key now
streams via `axum::body::Body::from_stream` instead of buffering — the
test asserts a 200 KiB file emits >1 frame end-to-end through the
router.
Frontend:
- lib/api/client.ts gains `fileUrl(key)` so components don't
reconstruct the `/api/v1/files/...` path manually.
- lib/api/chapters.ts gains `ChapterPage` type + `getChapterPages` (the
type is named ChapterPage to avoid colliding with `Page` from
client.ts, which is the pagination envelope).
- /manga/[id]/+page.svelte: overview with cover, title, author,
description, chapter list, and a disabled bookmark control (real
bookmarking lands in feat/bookmarks). Responsive at 640 px.
- /manga/[id]/chapter/[n]/+page.svelte: paginated reader. Current page
loads eagerly; next page is preloaded in a hidden img so navigation
feels instant. Keyboard handler maps ArrowRight/j/Space → next,
ArrowLeft/k → prev, Home/End → first/last; skips when the user is
typing in an input. Focus ring on the prev/next buttons.
- SSR is disabled on both routes via `export const ssr = false` so the
client-only fetch flow doesn't need to be replicated server-side; the
routes are interactive features, not SEO surfaces.
- E2E (e2e/reader.spec.ts): overview shows the title/cover/chapter
list; reader pages through three pages via ArrowRight, j, k, and
ArrowLeft, and the preload img holds the page-2 src on initial load.
Lockstep version bump to 0.6.0.
