reading_progress 0.0.1

A pure Dart engine for verified reading progress — confident-word milestones, active-dwell tracking, and reading-speed calibration.

Changelog

0.0.1

• Initial release.
• Pure Dart reading-progress engine: event-sourced reducer, confident-word accumulation (points + milestones), active-dwell engagement policy, per-book WPM calibration (Brysbaert-seeded EMA), page-completion gate (dwell + skim rejection), calibration period, session reading time, book-completion detection.
• Presence-based engagement: silent reading is credited via heartbeat Tick events within an idle cutoff (not just taps/scrolls). StepEngagementPolicy caps a step; idleCutoffMs / maxStepMs configurable.
• Last content page completes on finish / reader-close (any exit), since it has no forward page-turn — books can now reach 100%.
• Partial per-page dwell resumes across revisits (ReadingState.partials) — glancing ahead and returning never resets a page.
• Genre.unknown (default) → neutral seed for books with no genre.
• Swappable strategies: ReadingSpeedModel, EngagementPolicy, CompletionPolicy.
