# Purpose of this Document

This file serves as a comprehensive summary of the autonomous build process executed by the AI agent (Antigravity/Flash) for the Fenesta GBP Dealer Dashboard. It outlines the technical changes implemented, the hierarchy logic established, and provides clear instructions for testing the system in its current state (Phases 0-5).

## 🚀 Flash Build: Work Done (Phases 0-5)

### 1. What Was Accomplished

#### Phase 0: Project Cleanup & Restructuring

- **Modular Backend**: Restructured the monolithic prototype into a production-ready modular layout:
  - `auth/`: JWT handling, bcrypt hashing, and login routes.
  - `agency/`: Client management for Hashtag Orange.
  - `client/`: Dealer management and cumulative dashboards for Fenesta.
  - `dealer/`: Individual metrics and GBP post stubs.
  - `google/`: Mock API, sync services, and `direction_clicks` logic.
  - `middleware/`: Role-based access control (RBAC).
- **Environment Setup**: Configured `.env` and `config.py` to handle sensitive credentials and system settings.
- **Frontend Prep**: Removed legacy commented code from `index.html` and `app.js` to clear the way for V2 integration.

#### Phase 1: Database Architecture

- **Schema Deployment**: Implemented a 4-table relational schema using `pg8000`:
  - `users`: Core credentials with role mapping.
  - `clients`: Linked to Agency users.
  - `dealers`: Linked to Client records and `location_id`.
  - `metrics_cache`: Stores cached GBP data with a unique constraint on `(location_id, metric_name)`.
- **Seeding**: Initialized the system with the primary Agency Admin.

#### Phase 2: Authentication & Security

- **JWT Implementation**: Fully functional JSON Web Token system with 24-hour expiry.
- **RBAC**: Middleware that ensures an Agency admin cannot see Dealer data directly without permission, and Dealers can ONLY see their own data.
- **Password Flow**: Implemented `needs_password_change` flag logic to force users to update their credentials on first login.

#### Phase 3 & 4: Management Hierarchy

- **Agency Layer**: Hashatg Orange can now add "Clients" (e.g., Fenesta).
- **Client Layer**: Fenesta can now add "Dealers" and view a cumulative dashboard summarizing all their dealers' performance.
- **Sync Engine**: Created a background-ready sync function that populates the cache with mock data (including `direction_clicks`) whenever a dealer is added.

#### Phase 5: Dealer Dashboard

- **Metric Extraction**: Dealers can now fetch their individual performance metrics directly from the local cache.
- **KPI Expansion**: Integrated `direction_clicks` as a core KPI alongside views, impressions, and clicks.

### 2. 🧪 How to Test the System

To test the implementation, follow this sequential flow using a tool like Postman or the FastAPI Swagger UI (`/docs`):

#### Step A: Start the Server

```powershell
cd backend
.\venv\Scripts\python -m uvicorn app.main:app --reload
```

*Access the API documentation at: `http://127.0.0.1:8000/docs`*

#### Step B: Login as Agency Admin

- **Endpoint**: `POST /api/auth/login` (Use `OAuth2PasswordRequestForm` style / Form-Data)
- **Username**: `admin@hashtagorang.in`
- **Password**: `Admin@123`
- **Goal**: Receive the `access_token` and `role: agency`.

#### Step C: Create a Client (Agency Task)

- **Endpoint**: `POST /api/agency/clients`
- **Headers**: `Authorization: Bearer <ADMIN_TOKEN>`
- **Payload**:

```json
{
  "name": "Fenesta",
  "email": "admin@fenesta.com",
  "password": "Password@123"
}
```

#### Step D: Login as Client & Add Dealer

- **Endpoint**: `POST /api/auth/login` (as `admin@fenesta.com`)
- **Action**: Use the returned token to add a dealer at `POST /api/client/dealers`.
- **Payload**:

```json
{
  "name": "Delhi Dealer",
  "email": "delhi@fenesta.com",
  "password": "Dealer@123",
  "location_id": "LOC_DEL_001",
  "address": "Okhla Phase 3, Delhi"
}
```

#### Step E: View Dealer Dashboard

- **Endpoint**: `GET /api/dealer/dashboard` (Log in as `delhi@fenesta.com` first)
- **Goal**: See the JSON response containing the randomized mock metrics, specifically checking for `"direction_clicks"`.

### 3. ⚠️ Crucial Details & Credentials

| Entity | Email | Default Password | Role |
| :--- | :--- | :--- | :--- |
| **Agency Admin** | `admin@hashtagorang.in` | `Admin@123` | `agency` |
| **Client Admin** | `admin@fenesta.com` (created in Step C) | `Password@123` | `client` |
| **Dealer User** | `delhi@fenesta.com` (created in Step D) | `Dealer@123` | `dealer` |

#### Database Details

- **DB Name**: `fenesta_db`
- **DB Password**: `hnny1436`
- **Table Constraints**: `location_id` must be unique across all dealers.
- **Mock Mode**: `USE_MOCK_DATA=true` is enabled in `.env`. Real API calls are stubbed out for Phase 6.

#### JWT Configuration

- **Secret**: `xK9mP2qL7vR4tY8wN3bJ6hF1cA5dG0eZ9sU2iO7pM4kR8nQ1wX5vB3jH6fT0yL2`
- **Algorithm**: `HS256`

### 4. 🔧 Bug Fixes Applied (April 30, 2026)

A code audit was performed and the following issues were identified and fixed:

| # | Issue | Fix |
| :--- | :--- | :--- |
| 1 | **Duplicate `app = FastAPI()`** — `main.py` had two declarations (line 11 and 29). | Removed the first; single init with lifespan manager. |
| 2 | **`BackgroundTasks` imported but unused** — `sync_location_metrics` ran synchronously blocking the response. | Changed to `background_tasks.add_task(sync_location_metrics, ...)` for non-blocking execution. |
| 3 | **`APScheduler` missing from `requirements.txt`** — server would crash on fresh install. | Added `APScheduler>=3.10.0` to `requirements.txt`. |
| 4 | **No error handling in `sync_location_metrics`** — DB connection failure caused `AttributeError`. | Added null-check for DB connection + try/except/finally wrapping. |
| 5 | **`datetime.utcnow()` deprecated** — Python 3.12+ deprecation warning. | Replaced with `datetime.now(timezone.utc)` in `jwt_handler.py`. |
| 6 | **Wrong endpoint URLs in this document** — referenced `/clients/add` and `/dealers/add`. | Corrected to `/clients` and `/dealers`. |
