Local-first Flutter app that identifies the single behavioral change most likely to extend lifespan using hazard-based modeling. Features: - Risk engine with hazard ratios from meta-analyses - 50 countries mapped to 4 mortality groups - 6 modifiable factors: smoking, alcohol, sleep, activity, driving, work hours - SQLite local storage (no cloud, no accounts) - Muted clinical UI theme - 23 unit tests for risk engine Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
