Native Audio Overhaul & Infrastructure Resilience Today marking the end of the exam-induced pause, we launched a major update to the native Android scheduler and our backend notification pipeline. This update focused on sensory reliability and infrastructure stability.

​
1. Native Audio Infrastructure Evolution

We moved away from the unpredictable system-default ringtones into a fully bundled, production-grade audio pipeline:
  • MediaPlayer Architecture: Replaced the generic RingtoneManager with a robust MediaPlayer implementation in AlarmActivity. This guarantees seamless, infinite looping of custom audio clips across all Android API levels, bypassing inconsistent OEM behaviors.
  • Production Bundling: Directly bundled alarm_start.mp3 (action pulse) and alarm_end.mp3 (finality hit) into the native /res/raw directory.
  • DND Piercing: Forcibly routed all audio streams using USAGE_ALARM attributes. This ensures that verification alarms aggressively pierce through “Do-Not-Disturb” (DND) and silent modes.

​
2. ‘End-Alarm’ Expansion & UI

We introduced a universal “closure” notification to ensure users know exactly when their opportunity to verify has expired:
  • END_ALARM Evaluation: Engineered a new temporal branch in the native math engine to fire at the exact millisecond a window closes.
  • Time’s Up UI: Designed a distinct red ”⏰ Time’s Up!” lockscreen layout for these finality alarms.
  • Sovereign Signaling: Decoupled this alarm from local database mutations. It acts purely as a frontend sensory cue, while the backend Convex runner handles the authoritative grading and penalty logic in the background.

​
3. Backend Infrastructure: Migration to Resend

To improve the reliability and deliverability of our accountability reports, we overhauled our email transport layer:
  • Brevo to Resend: Fully migrated the critical email transport pipeline away from Brevo.
  • HTTP API Integration: Switched to the robust Resend HTTP API for executing our “Embarrassing Photo” and “Breach” notifications, ensuring faster and more reliable delivery to accountability partners.

​
4. Hardware Security & Verification Fixed

  • JailMonkey Shield: Re-secured the root layout with JailMonkey interrogation to proactively block access from jailbroken devices, mock location spoofers, and developer-mode users in production.
  • Waiver Deadline Restoration: Replaced the temporary 6-second test delays with the actual configured deadline_minutes logic in the armAccountabilityContract service, restoring production-grade redemption windows.
  • Ghost Duplicate Fix: (Commit 7bafded) Expanded the collision search window in generateSeries to prevent spawning duplicate task instances over locked occurrences.
