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)

Already running an older OpenTasker from these releases? This build is signed with the same key as v0.2.59, so it installs as a normal in-place update. (If you sideloaded a build signed with a different key, uninstall it first.)

What's new since v0.2.59

• Flow control actions — if / else / end if, for each / end for over array variables, and stop, with balanced-block validation.
• Reusable sub-tasks — task.run calls another task by id/name (shared variables, depth-bounded to 8 levels).
• Bluetooth trigger — profiles can fire on device connect/disconnect (event=bluetooth).
• OEM battery-killer guidance — Setup detects Samsung/Xiaomi/OnePlus/Oppo/Realme/Vivo/Huawei and shows per-vendor reliability steps with deep-links.
• Typed run-log source — run logs now carry a structured trigger source for cleaner filtering.
• Complete light theme — the Catppuccin Latte light palette now defines every semantic token, so the UI is coherent in light mode (previously only dark was fully styled).
• Maintenance — removed unused Hilt/Dagger, raised the Gradle build heap to stop OOM build crashes, and refreshed the README.
