# Phase 1: Foundation (Headless-Plus) Walkthrough

## 1. Directory Structure Created
Scaffolded the following structure for FAEA:

```
/home/kasm-user/workspace/FAEA/
├── docker-compose.yml
├── Dockerfile
├── requirements.txt
├── src/
│   ├── core/
│   │   ├── session.py       # SessionState Class (Implemented)
│   │   └── handover.py      # HandoverValidator (Implemented)
│   ├── browser/
│   │   └── Dockerfile       # Camoufox Scaffolding
│   ├── extractor/
│   │   └── Dockerfile       # Curl Scaffolding
│   └── infra/
│       └── storage.py       # RedisStorage (Implemented)
└── tests/
    └── unit/
        └── test_session_core.py # Unit Verification
```

## 2. Infrastructure Scaffolding
Created `docker-compose.yml` defining services:
- **Orchestrator**: Python controller.
- **Redis**: Shared state store.
- **Camoufox**: Browser tier.
- **Curl-Extractor**: Network tier.

## 3. Verification Results

### session.msgpack Serialization
Verified that `SessionState` correctly serializes to msgpack with HMAC signature and deserializes back.

### Handover Protocol
Verified `HandoverValidator` logic for:
- User-Agent vs TLS Fingerprint consistency.
- `sec-ch-ua` header derivation from User-Agent.

**Test Output:**
```
tests/unit/test_session_core.py .. [100%]
2 passed in 0.06s
```

## 4. Next Steps
- Implement full `CamoufoxManager` in Phase 2.
- Implement full `CurlClient` request logic.
