- AnswerReveal: decrypt partner's selectedOptionTexts from option IDs (showed raw ids)
- FirestoreAnswerDataSource: tolerate Timestamp/Date in updatedAt (serverTimestamp crash)
- FirestoreReleaseKeyDataSource: tolerate PERMISSION_DENIED on existence check (sender can't read)
- QuestionThreadRepository: runCatching status update (legacy lowercase status blocked submit)
- PartnerNotificationManager: suppress notification for active thread, deep link to thread
- ActiveThreadMonitor: new class tracks which thread user is reading (suppresses own notifs)
- DesireSync/HowWell/ThisOrThat: re-open guard skips INTRO if already answered; blank sessionId guard
