Summary

Adds More → Highlights in the EPUB reader. The current book’s list shows saved quotations, semantic colours and locations in reading order. Quotations remain selectable and can expand; invalid or unavailable locations keep their saved text visible.

Selecting a row opens its exact canonical range, including repeated text and selections far into a long paragraph. The mounted reader is retained while the list is open. Cancellable navigation protects saved progress while loading a chapter, validates the destination, and restores the prior reading location on failure; an unverified rollback keeps the bookmark protected until the reader is reopened. Rotation retains the existing resize/reanchor policy.

Jump navigation supports horizontal-text reflowable EPUBs. Fixed-layout and other writing-mode quotations remain readable/selectable without a guessed jump.

This completes the list/navigation increment separately from sync and notes. Exact navigation spans reader readiness, DOM geometry and progress/rollback state; targeted tests accompany each layer.

Component(s)

• Android app
• Sync server
• Documentation
• CI / build

Validation

• Production Kotlin and debug APK build passed; APK contains the frozen production helper and excludes test EPUBs/spike activity.
• App/reader debug checks passed, including nine list UI cases, twelve navigation transactions and three viewport/progress regressions.
• All 26 browser regressions passed, including duplicate ranges, late text in one paragraph, reflow, RTL/fractional page geometry, origin pins, mixed snapshot rejection and textless-origin fallback.
• Independent source and final native-evidence review passed with no unresolved findings. API36 native checks passed: per-book list/Back and isolation/empty state; unavailable-quote display and wrapped-prose expansion/collapse; exact second duplicate, second cross-paragraph pair and offset 7473 in a repeated long text node; 130% font/Dark reflow; page-turn and relaunch bookkeeping. A stale cross-resource target stages its chapter, restores the loaded textless cover, and preserves the durable locator.
• Server/shared identity/schema sources are unchanged; reuse the validated PR1 server suite (990 passed and Ruff clean) against the identical server Git tree.
• Pre-commit passed on all 29 PR files.
• Full Android CI and CodeQL passed on 9613ae6: debug/release builds, all unit tests, lint, license drift, repository guards and release tooling checks. The release job is correctly skipped for a PR.
