Lagrange 1.3.0

Release notes

Highlights

Added a Statistics destination to the profile menu above Achievements.
- Shows tracked, started, in-progress, and completed books.
- Shows mean library progress.
- Shows daily reading duration and reading-event counts.
- Handles loading, unsupported older servers, retryable errors, and partial or empty responses.
Expanded audiobook History with BookOrbit server reading sessions and reading attempts.
- Local app sessions appear first and remain the authoritative source for exact playback seeking.
- Server sessions appear afterward as analytics-level history.
- Local entries remain seekable; server entries are informational because BookOrbit does not provide exact audio positions or file IDs.
Added centered Lagrange login branding with the subtitle “a BookOrbit reader”.
Added compact Book Detail metadata-source links for the supported BookOrbit providers, including RanobeDB, Audnexus, ComicVine, and Aladin.
Improved metadata-provider URL handling through a centralized provider-link registry.
Continued reader and audiobook refinements, including validated EPUB/comic behavior, audiobook playback restoration, and Android external audiobook controls for Back 10, Play/Pause, and Forward 30.

Validated on the Samsung Galaxy S24 for the current reader/media, History, Statistics, and external audiobook-control flows.
Full JVM test suite passes with 336 tests, zero failures, zero errors, and zero skips.
lintDebug passes.
Debug APK assembly passes.

Server audiobook sessions and reading attempts are analytics records, not exact playback state. They cannot recreate a precise local seek position or distinguish audiobook files when a book has multiple files.
Additional BookOrbit Statistics metrics, including heatmaps, source distribution, and peak-hours analysis, remain future expansion beyond the current summary and daily-reading view.
Offline RAR/7z extraction for downloaded CBR/CB7 remains deferred; server-backed extraction is still required where applicable.
Direct OIDC/SSO authentication is deferred. Native username/password authentication remains the current login flow.

This release does not replace local audiobook history. Existing local exact-position history remains available and is displayed before server history.
No migration action is required for existing readers, downloads, progress, or local audiobook history.
