Mobile Apps Overview

Three role-specific apps — Parent, Student, Teacher — riding the shared Greenwood backend APIs. App-delivery layer for AY 2026-27 · Phase 2 (Engagement & Mobile).
ℹ️
App-delivery layer only. APP-001 owns the app shell, mobile auth, push registration, offline outbox + idempotent sync, per-app dashboards, force-upgrade gating, and app-only screens (payment, live bus tracking). All business logic is consumed from the module epics (ATT-001, HW-001, EXAM-001, FEE-001, TT-001, TRANS-001). Full interactive app mockups land in a later phase.

Cross-cutting Capabilities

Offline outbox + idempotent sync
Local cache + outbox with idempotency keys. Replays exactly once; conflicts surfaced, never silently overwritten.
⬆️
Force-upgrade gating
Launch-time min-version policy per app + platform. Soft-nag (dismissible) or hard-block (mandatory).
Offline sync● Confirmed
✅
Offline flows verified for attendance marking and homework submit. Outbox replays idempotently on reconnect.
Version policy● Soft-nag

📌
Offline flows confirmed

For Phase 2 launch the offline-capable boundary is locked to Teacher offline attendance marking and Student offline homework submit (with PLAT-001 signed-URL attachment upload). Both write to a local outbox with an idempotency key, show a clear pending sync state, and replay exactly once to ATT-001 / HW-001 on reconnect under a server-authoritative + last-writer-wins conflict policy. Marks, fees and transport are read-cached only — not offline-mutable this phase.
