Add a Share Book feature that generates an expiring HTTPS share URL plus a
parallel readest://share/{token} deep link. Recipients land on /s/{token},
where logged-in users can one-tap "Add to my library" (R2 server-side
byte-copy) and anonymous users download the book or open it in the app.
Sharers manage active links from a dedicated "Manage Shared Links" panel
under user settings.
Highlights:
- 9 new App Router endpoints under /api/share (create, [token], cover,
og.png, download, download/confirm, import, revoke, list).
- /s landing page with branded next/og chat unfurl image and SSR auth-cookie
detection so logged-in recipients see "Add to my library" as the primary
action without layout shift.
- Server-side R2 byte-copy for /import preserves the project's existing
invariant that every files.file_key is prefixed with its row's user_id;
stats / purge / delete / download routes work unchanged. URL-encodes the
copy source so titles with spaces or '&' don't break the copy.
- Universal 7-day expiry cap, no tier differentiation, no "never". DMCA-risk
reduction. Picker defaults to 3 days.
- Position-aware shares: "Share current page" toggle (off by default for
privacy) attaches the sharer's CFI; recipient lands at the same paragraph.
- Per-user 50-share cap, rate limiting via Cache-Control: no-store on
token-bearing responses, atomic SQL increment for download_count via a
SECURITY DEFINER function so the public confirm beacon stays safe under
concurrent fire.
- Soft revocation: presigned download URLs (5-min TTL) cannot be cancelled
before TTL; documented as accepted v1 behavior.
- token + token_hash hybrid storage: public endpoints look up by hash and
never select the raw token, so accidental SELECT-* leakage on a public
route can't expose the bearer credential.
- Mobile / desktop Tauri share via tauri-plugin-sharekit; web falls back to
navigator.share with a clipboard fallback when no native share method
exists. Share-sheet dismissal no longer silently copies.
UI:
- New Dialog with a settings-card group: iOS-style segmented duration picker
+ toggle slider for "Share current page", on a single row each.
- Reader top-bar Share button, library context-menu Share entry, manage-
shares list with cover thumbnails and overflow menu.
- New <SegmentedControl> primitive in src/components for reuse.
Coverage:
- Unit tests for token utils + URL parser (20 new tests, full suite at 3445).
- 31 locales translated for all new strings; en plurals hand-added per the
project's hand-curated en convention.
DB migration in docker/volumes/db/migrations/002_add_book_shares.sql adds
the book_shares table, RLS policies, and the increment_book_share_download
RPC. Migration is idempotent.
