Implementation plan improvements:
- Fix event name consistency: DOZE_FALLBACK → EVT_DOZE_FALLBACK_TAKEN in Test Matrix
- Lock receiver export policy as AC: only BootReceiver exported
- Handle unknown Content-Length: add streaming guard for -1 responses
- Ensure single joined error mirrors AC: validation failures return one joined message
- Add webDir echo and device idle hint to diagnostics: include webDir path and isDeviceIdleMode
- Make degradation visible in UI AC: matrix shows 'Degraded timing (Doze)' when fallback active
- Add Room migrations guard: no-op migration and fallbackToDestructiveMigration(false) test
Analysis doc improvements:
- Trim WAKE_LOCK guidance: not required unless explicitly acquiring/releasing wakelocks
- Add Boot receiver priority note: android:priority has no effect for BOOT_COMPLETED
- Fix application android:name accuracy: only set if custom Application class exists
- Mirror Cordova compat note in Build section: include only when using Cordova plugins
- Annotate Mermaid flow with canonical errors: show where canonical errors are produced
- Link Truth Table to test UI buttons: integrate with Open Channel/Exact Alarm Settings buttons
All changes maintain existing structure with surgical precision edits.
