- GPS First-Tap Refresh Hardening: Enforced strict request_id correlation in LiveMap and isolated native acquireFreshFix() to eliminate pre-request stale checkpoint acceptance on first tap.
- Continuous Automatic 15-Second Tracking: Restored offline sync timer in startNativeService() and eliminated competing background timers on Android to ensure robust periodic telemetry while stationary.
- Intelligent 5-Second Travelling Tracking: Implemented dual-threshold speed hysteresis (1.2 m/s / 4.3 km/h) in native StackerLocationService, dynamically shifting to 5-second cadence when in transit and smoothly returning to 15 seconds when stationary.
- Production Release Stability: Upgraded Kotlin plugin integration to 2.1.0 and aligned Android application metadata with v1.0.16+17.
