- detect/PresenceEngine.kt: identity-agnostic streaming detector for key-rotating clones (novel-churn gate, seamless-handover chain, co-movement gate, coherence). Full design in docs/detection-rotation-clone.md.
- Wired into ScanService as a parallel signal; CONFIRMED verdict raises a distinct rotating-tracker alert (softer tiers stay silent pending real-capture validation).
- PresenceEngineTest: synthetic clone (moving -> CONFIRMED), stationary clone (gated), single real tracker + far-ambient (CLEAR).
- CI now runs :app:testDebugUnitTest so the engine has behavioural verification, not just a compile check.

paper/vigil.md: per-ecosystem detection methodology (Apple/FMDN/Samsung/Tile/DULT) and the rotation-clone presence engine (identity-agnostic detection, the rotation-rate squeeze, FP analysis, honest floor). Draft working paper accompanying the reference implementation.

- Rewrote MainScreen: top bar, prominent status hero (idle/clear/watching/alert), active vs trusted sections, per-tracker cards with status icons, and a detail bottom sheet with co-movement evidence + trust action.
- Sensitivity selector with per-mode explanation; on-device/no-network footer.
- core-ktx 1.13.1->1.15.0, activity-compose 1.9.3->1.10.1 (kept the proven Kotlin/AGP/Compose matrix for build stability).
