feat: Import Readest highlights as clippings - #92
If you highlight text in the Readest app, that highlight never shows up in CrossPoint Sync or on your CrossPoint reader.
Pointing Readest at CrossPoint Sync (its "KOReader Sync" setting) only shares where you are in a book, not highlights.
Linking Readest under Connectors sends highlights from your reader to Readest, but nothing comes back.
What this PR changes
Readest highlights now come back to Sync. They show up as clippings, like the ones you make on your reader, and from there reach your reader and the app.
Sync looks up the highlighted text in Readest's copy of the book to find the right spot.
If the text isn't there, the highlight is skipped rather than placed in the wrong spot.
Highlights Sync already has are not added twice.
Bug fix: Sending a clipping to Readest could fail with book is not in your Readest library, even though the book was uploaded. That happens when Readest has the file but not a library entry for it. Sync now finds the book by its file instead.
What still doesn't work
Editing or deleting a highlight in Readest after it was imported doesn't change it in Sync.
Readest highlights now come back as clippings for books in the Readest
cloud library. Each is placed by its CFI in Readest's copy of the EPUB
and kept only when its text is there.
Readest stores notes under the file's own hash, which may have no
library entry. Pull reads that hash first, and push now falls back to
it too instead of failing with "not in your Readest library".

Walkthrough
The Readest connector imports eligible Readest highlights as CrossPoint clippings and can push highlights for downloaded books without a Readest library entry. Highlight pulls receive connector context. Readest service descriptions now describe two-way highlight synchronization.
Changes: Readest highlight synchronization
Layer / File(s)
Summary
Connector context and outbound fallback src/connectors/types.ts, src/connectors/fanin.ts, src/connectors/readest.ts, test/readest.test.ts
pullHighlights accepts connector context, and pollConnector passes the database, user ID, and matched document. Outbound pushes use the document hash when no library entry exists. Tests cover the fallback and the non-retryable error for a missing EPUB link.
Readest note retrieval and conversion src/connectors/readest.ts, test/readest.test.ts, app/src/Settings.jsx, src/routes/landing.ts
The connector retrieves notes by document hash or matching library-copy hash. It filters notes and converts valid CFI selections to inbound offsets when their text matches the EPUB text. Tests cover caching, filtering, and progress reads. Service descriptions refer to two-way highlight synchronization.
If Readest has notes for a book file that is not uploaded to Readest Cloud, highlights stored under the library copy may never be imported. Handle the missing-file error per copy before merging, or accept the limitation knowingly.

For each resolvable note, epubRangeOffsets parses the chapter twice. Notes that fail the quote check remain unknown, so later progress reads repeat that work. Several such notes can add substantial work to each progress refresh.
Consider reusing parsed chapter data across note resolutions. Do not suppress retries by note ID alone: a later edit can make the note valid.

removing the 40-character truncation while preserving the existing startsWith

- Around line 373-390: Update the highlightsIn and readestBook flow so finding
notes under m.externalId does not skip checking the matching library copy. Fetch
and retain notes for each available book hash, resolving each copy’s notes
against its own EPUB while preserving the existing retry behavior.

383-387: Low value
Negative-search cache can hide highlights when the sync API fails or the book is later uploaded.
noCopyUntil is set when readestBook returns null. The cache key includes m.externalId but not whether the library has changed. A user who uploads the book to Readest then waits up to one hour for highlights to be pulled. The note lookup by the document hash (line 381) still runs on each pull, so only the library-copy path is delayed. This is a documented tradeoff (see the comment on line 355). No change is required, but consider noting the delay in the UI hint.

334-345: Functional Correctness
The cleanup hook restores real timers.
The file-level afterEach restores timers after the cited test, so its shifted clock does not persist into later tests.
- Import highlights from the library copy too, not only the file's own copy.
- Require the whole highlight text to match at its position.
- Remember highlights that can't be placed, so their book isn't downloaded
again on every sync. An edited highlight is tried again.

- Line 396: In pullHighlights, handle failures from the per-copy epub call so a
non-retryable ConnectorOperationError that does not require reauthentication
skips only the current copy and continues the copies loop. Rethrow retryable,
needsReauth, and unknown errors; add a test where the DOC copy returns a 404 and
highlights from the library copy are still imported.

Skip only the missing-copy error
The new catch correctly skips a missing-copy 404, but it also skips any non-retryable ConnectorOperationError; epub() produces one for, for example, a 403 from the book link or download. If that is the only copy, pullHighlights() resolves with no items and fan-in sees no failure to retry, silently losing the refresh's highlights. Restrict the continue to the not-in-library error and propagate other failures.

Verify offsets against the matched EPUB
readestBook() may select a library copy by title and author when its hash differs from m.externalId; these offsets are computed against that downloaded copy, but importHighlights() stores them on the matched document used by the reader. If the same-title EPUBs have different spine order or text layout, the quote check only proves the text is at this CFI in Readest's copy, so the imported clipping can point at an unrelated passage in the reader's book. Verify the offsets against the matched document before persisting them, or skip cross-hash copies.
