## Tasks
## Sync Reliability and Reliability Runner
Implemented a robust verification system to ensure the local database accurately
reflects the server state across multiple accounts and protocols.
- **Reliability Check**: Added `verifySyncReliability` to `EmailRepository` to
compare local UIDs/IDs and flags against the server's "ground truth".
- **Reliability Runner**: A background service (`lib/core/sync/reliability_runner.dart`)
that periodically identifies discrepancies.
- **Database Support**: Added `SyncHealth` table (Schema v19) to store verification
results.
- **UI Integration**: Added "Sync health" indicators to the account list tiles and
a manual "Verify sync health" menu action.
- **Comprehensive Testing**: Verified with a new integration test suite
(`test/integration/sync_reliability_test.dart`) covering both IMAP and JMAP
paths.
## Coverage Gate Cleanup and Verification Test
- **Reduced Exclusions**: Removed well-tested widgets (`try_connection_button.dart`, `add_account_screen.dart`, `edit_account_screen.dart`) from the unit-test `_excluded` list in `scripts/check_coverage.dart`.

# Plan Log
## 2026-05-09
- Started work on Sync Reliability (Task 1/5 from next.md).
- Added `verifySyncReliability` to `EmailRepository` interface and models.
- Implemented `verifySyncReliability` in `EmailRepositoryImpl` for IMAP and JMAP.
- Added `SyncHealth` table to database (Schema v19).
- Created `ReliabilityRunner` for periodic verification.
- Integrated sync health indicators in `AccountListScreen` UI.
- Added manual "Verify sync health" action.
- Verified with new integration tests in `test/integration/sync_reliability_test.dart`.
- All integration tests (IMAP and JMAP) passing.
- Fixed several compilation and analysis issues.
