OpenTasker v0.2.67

Deep engineering audit — thread safety, correctness, UX, and design system hardening

Thread safety

• ArrayStore and VariableStore local scopes now use ConcurrentHashMap to prevent crashes in parallel automation mode
• WiFi/Connectivity monitor state and CameraMicContextEvents callbacks marked @Volatile
• AppOps watchers now properly unregistered on service destroy (was leaking)

Correctness fixes

• HTTP response decoding no longer corrupts multi-byte UTF-8 characters at read boundaries
• Brightness auto mode correctly sets SCREEN_BRIGHTNESS_MODE instead of writing -1
• Screen timeout clamps to 30 min max to prevent integer overflow
• Sunrise/sunset calculator uses event-time DST offset instead of noon (fixes 1-hour error on DST transition days)
• Battery level and charging state seeded at service start so battery-based profiles match immediately
• TTS action guards against double-resume crash from racing callbacks
• Flow graph card handles missing profile node gracefully

Safety

• Vibration capped at 10 seconds
• Queued task depth per profile capped at 50 to prevent unbounded memory growth
• Database backup uses TRUNCATE WAL checkpoint for safer consistency
• Notification PendingIntent request codes use hash to prevent overflow

UX & design

• Disabled element overlay fixed for light theme (was drawing black)
• Warning color changed from green to warm amber/peach
• Navigation icons have accessibility labels
• Card radius consolidated into design system token (Radii.xxl)
