- Register AppDatabase.MIGRATION_3_4 so v3 databases upgrade without data loss - Query teacher schedule periods by containment (weekStart<=x AND weekEnd>=x) instead of exact weekStart, matching 2-week catalog windows - Clip buildTeacherSchedule days to the requested week range - Add weeksFor() to enumerate weeks of a catalog window for the UI selector - Serialize syncPeriod body with a Mutex to protect the unique index - Rethrow CancellationException before generic catch; version loadRevision checks so stale observers/loads are cancelled - Sync job tracking in PickerViewModel; keep loading true while empty - Drop dead selectTeacher helper
