Egregoria Android 0.6.3-android.1 — Stable Gesture Fix
Released: 2026-08-04
Package: org.egregoria.android
Android package version: 0.6.3
Game/mod compatibility version: 0.6.1
Minimum Android: 8.0 (API 26)
Public APK ABI: arm64-v8a

GESTURE FIX
- One-finger drag pans the camera.
- Two-finger pinch changes zoom only.
- Two-finger twist changes yaw rotation only.
- Parallel two-finger translation does nothing.
- Pinch and twist use thresholds, hysteresis, deterministic pointer pairing,
  and a locked mode for each active two-finger gesture.
- Baselines reset when the active pair changes, preventing jumps during
  one-to-two and two-to-one transitions.
- A brief unrelated third contact preserves the established pair and mode.
- Android edge scrolling is suppressed while any touch contact is active.
- Obsolete synthetic right/middle mouse paths no longer compete with native
  touch-camera deltas.

VERIFICATION
- Engine test suite: 31 passed, including five gesture regressions.
- Python modding suite: 16 passed.
- Desktop build passed.
- x86_64 Android build passed.
- ARM64 Android build passed.
- API-35 emulator, real UI Automator gestures:
  * pinch changed distance by -217.86 and yaw/pitch/position by exactly zero;
  * twist changed yaw by -1.3291 rad and distance/pitch/position by zero;
  * parallel two-finger drift changed all camera fields by exactly zero;
  * one-finger drag changed horizontal position by 124.09 with yaw/pitch/
    distance unchanged.
- Production APK upgrade, rendering, alignment, ABI, embedded SAF bridge,
  signing certificate, and v2/v3 signatures verified.

SECURITY AND MODDING
- RustPython 0.5 runs trusted ZIP mods in process.
- Import uses Android's Storage Access Framework.
- Approval remains bound to manifest ID plus archive SHA-256.
- Defensive ZIP validation, dependency handling, and persistent state remain
  unchanged from 0.6.1-android.1.

LIMITATIONS
- Sustained testing on a physical ARM64 phone remains pending.
- Python mods are trusted in-process code, not a security sandbox.
- Native CPython extension modules are unsupported.
