# MVP Implementation Summary

**Date:** January 2025  
**Status:** ✅ **COMPLETE - Backend Ready for Flutter Agent + Citizen MVP**

---

## What Was Done

### 1. Backend Readiness Audit ✅
- Comprehensive audit of all API endpoints
- Verification of multi-tenant behavior
- Confirmation of authentication flow
- Validation of authorization policies

### 2. Identified Gaps ✅
- 3 critical gaps identified
- 1 optional gap identified
- All gaps documented in `CITIZEN_AGENT_BACKEND_READINESS.md`

### 3. Implemented Minimal Fixes ✅

#### Fix 1: Device Token Registration Endpoint
**File Created:** `app/Http/Controllers/Api/V1/DeviceTokenController.php`

**Endpoints:**
- `POST /api/v1/device-tokens` - Register/update device token
- `DELETE /api/v1/device-tokens/{token}` - Remove device token

**Features:**
- Upsert behavior (update if exists, create if new)
- Supports android, ios, web device types
- Tracks device_id for multiple devices per user
- Sets is_active and last_used_at automatically

**Request Example:**
```json
POST /api/v1/device-tokens
{
  "token": "fcm_token_string",
  "device_type": "android",
  "device_id": "unique_device_id"
}
```

#### Fix 2: Audio Support for Voice Notes
**File Modified:** `app/Http/Requests/Incidents/CreateIncidentRequest.php`

**Changes:**
- Added `m4a, aac, mpeg, mp3` to allowed MIME types
- Now supports: jpeg, jpg, png, gif, webp, mp4, mov, pdf, **m4a, aac, mpeg, mp3**

**File Modified:** `app/Http/Controllers/Api/V1/IncidentController.php`

**Changes:**
- Added `determineMediaType()` method
- Automatically detects audio files and sets `media_type = 'audio'`
- Supports: image, video, audio, document

#### Fix 3: Organization Info in Response
**File Modified:** `app/Http/Resources/IncidentResource.php`

**Changes:**
- Added `organization` object to response
- Includes organization `id` and `name`
- Loaded automatically in all incident endpoints

**Response Example:**
```json
{
  "id": 1,
  "organization_id": 1,
  "organization": {
    "id": 1,
    "name": "CIE Electricity"
  },
  ...
}
```

#### Fix 4: Separate Media Upload Endpoint
**File Modified:** `app/Http/Controllers/Api/V1/IncidentController.php`

**New Method:** `addMedia(Request $request, Incident $incident)`

**Endpoint:** `POST /api/v1/incidents/{id}/media`

**Features:**
- Add media to existing incidents
- Supports images, videos, audio, PDFs
- Policy-protected (requires update permission)
- Returns uploaded media resources

**Request Example:**
```
POST /api/v1/incidents/1/media
Content-Type: multipart/form-data

media[]: [file1.jpg, file2.m4a]
```

### 4. Added Feature Tests ✅
**File Created:** `tests/Feature/CitizenAgentMvpTest.php`

**Test Coverage:**
1. ✅ Citizen can create incident and backend routes it to org
2. ✅ Citizen cannot access incidents they didn't create
3. ✅ Citizen can only see own incidents in list
4. ✅ Media upload accepts image and audio
5. ✅ Device token upsert works
6. ✅ Separate media upload endpoint works
