110+ pre-loaded comment templates categorized by performance level (Excellent/Good/Average/Below Average/Conduct/Improvement/Attendance)

Streamlined from 4 states to 2 (Submitted/Locked). Teachers can update submissions until admin locks. Student performance stats in comment modal.

Real-time academic performance display in comment modal. Nursery: Average/Grade/Position. Primary: Average/Aggregate/Division/Position.

Refactored 1,600-line seed script into 6 modular files (83% reduction). Reusable factories for schools, students, grades, and metrics.

Fixed authentication middleware to allow public access to all marketing pages (about, pricing, contact, careers, etc.).

School admins can lock all class comments at once when all teachers have submitted. Lock is permanent and prevents all edits.

Fixed nursery reports to display EE/ME/AE/BE descriptive grades instead of D1-F9. All nursery classes (Baby, Middle, Top) now use uniform grading with Marks/Grade/Teacher's Remarks format.

Fixed pre-existing TypeScript/import errors (calculateUNEBAggregate, updateClassSchema, student.class.subjects). Build now compiles successfully.

IndexedDB-based sync queue for offline actions. 4 sync targets: grades, attendance, fees, comments. Automatic background sync on reconnection. Server-wins conflict resolution with user notifications.

VAPID-based self-hosted push notifications. 3 triggers: report card published (teachers), grades approved/locked (specific teacher), term reminder (all staff 7 days before term). Subscription management with auto-cleanup of expired subscriptions.

Tiered caching strategies with Serwist. NetworkFirst for API data (5-min fallback), CacheFirst for static assets (30-day TTL), never cache auth/export routes. Offline page fallback for all document requests.

Extended grading system for UCE and UACE with subject combinations and principal/subsidiary grading. A-Level points calculation fixed, O-Level achievement levels displaying correctly.
