## Task ID: 8-9 — Illness Reporting + Communication Builder
**Date:** 2025-01-21
**Agent:** illness-communication-builder
**Status:** Completed
### Summary
Built the **Illness Reporting with Parent Approval** and **Student-Teacher Communication Rooms** features for CompetenceTrack. These are critical features for a German school platform: illness reports require parent approval before becoming visible to teachers (privacy compliance), and communication rooms provide private student-teacher conversation channels.
### Files Created
1. **`/src/app/api/illness-reports/route.ts`** — GET, POST endpoints
2. **`/src/app/api/illness-reports/[id]/route.ts`** — GET, PUT, DELETE endpoints
3. **`/src/app/api/illness-reports/approve/route.ts`** — POST endpoint for parent approval
4. **`/src/app/api/communication-rooms/route.ts`** — GET, POST endpoints
5. **`/src/app/api/communication-rooms/[id]/route.ts`** — GET, PUT, DELETE endpoints
6. **`/src/app/api/communication-rooms/[id]/messages/route.ts`** — GET, POST endpoints
7. **`/src/components/illness-reporting-view.tsx`** — Full illness reporting UI
8. **`/src/components/communication-view.tsx`** — Full communication rooms UI
### Files Modified
1. **`/src/lib/i18n.ts`** — Added 80+ i18n keys (DE + EN) for illness and communication
2. **`/src/lib/store.ts`** — Added `'illness'` and `'communication'` to ViewName type
3. **`/src/components/app-layout.tsx`** — Added nav items and view rendering for illness and communication
### Changes Made

- TEACHER: See only approved reports (isVisibleToTeacher = true)
- SCHOOL_ADMIN/VICE_PRINCIPAL: See all approved reports
- SUPER_ADMIN: See all reports
**POST `/api/illness-reports`** — Create illness report:
- STUDENT can report (reporterType: "student") — needs parent approval, not visible to teachers
- PARENT can report (reporterType: "parent") — auto-approved, visible to teachers/admin
- Student reports: parentApprovalStatus = "pending", isVisibleToTeacher = false, isVisibleToAdmin = false
- Parent reports: parentApprovalStatus = "approved", isVisibleToTeacher = true, isVisibleToAdmin = true
**PUT `/api/illness-reports/[id]`** — Update report:
- PARENT can approve/reject pending reports
- STUDENT can update own pending reports (before parent approval)
- SCHOOL_ADMIN/VICE_PRINCIPAL can also approve/reject
**DELETE `/api/illness-reports/[id]`** — Only the reporter or admin can delete

- Sets parentApprovalStatus, isVisibleToTeacher, isVisibleToAdmin
- Records parentApprovedBy and parentApprovedAt
#### 2. Communication Rooms API Routes

- If reason provided, sends it as first message
**PUT `/api/communication-rooms/[id]`** — Teacher accepts/rejects/closes room:

#### 5. i18n Keys

### Design Decisions
- Used Lucide icons exclusively (Heart for illness, MessageSquare for communication)
- Used framer-motion for all animations (entrance, hover, expand)
- Used existing shadcn/ui components (Card, Badge, Button, Dialog, Input, Select, Textarea, Tabs, ScrollArea)
- All text uses the i18n system via `t()` function
- Maintained responsive design patterns (mobile-first, grid breakpoints)
- Used emerald green (#10b981) as accent color throughout
- Privacy-first: student illness reports are NOT visible to teachers until parent approves
- Communication rooms are private: only student and teacher can see messages
- Admin can monitor for safety but not participate
- Polling every 5 seconds for real-time feel in communication rooms
- Database schema already had the models (IllnessReport, CommunicationRoom, CommunicationRoomMember, CommunicationMessage) — no schema changes needed
### Lint Results
- ESLint: Passed (no errors in new files)
- TypeScript: No type errors
- Database: Already in sync (no migration needed)
