🏗️ Microservice Responsibilities

• Database Routing: Interfaces with Supabase PostgreSQL to handle all student and faculty data transactions.
• Automated Daemon: Runs a node-cron job managed continuously by PM2 that scans for pending assignments and calculates dynamic deadlines.
• Notification Deduplication: Intercepts overlapping database triggers and utilizes memory-bank validation to guarantee a single Firebase Cloud Messaging (FCM) push payload per physical device.
• Secure Cloud Archiving: Utilizes the AWS SDK and IAM Roles for credential-less, automated JSON log backups directly to AWS S3.
