# 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
|
|
```
|
|
|
|
## Phase 2: Core Components (Headless-Plus) Walkthrough
|
|
|
|
### 1. Implementation
|
|
- **Browser Tier**: Implemented `CamoufoxManager` in `src/browser/manager.py`.
|
|
- Features: `__aenter__`/`__aexit__` for memory safety, session state extraction.
|
|
- **Extractor Tier**: Implemented `CurlClient` in `src/extractor/client.py`.
|
|
- Features: `chrome120` impersonation, session consumption (Cookies/Headers).
|
|
|
|
### 2. Verification Results
|
|
|
|
#### Automated E2E Test (`tests/e2e/test_handover.py`)
|
|
- **Status**: PASSED.
|
|
- **Scope**: Verified that `CurlClient` successfully consumes `SessionState` extracted from `CamoufoxManager` and matches the User-Agent against a local mock server.
|
|
|
|
#### Manual TLS Verification (`tests/manual/verify_tls.py`)
|
|
- **Status**: FAILED (Expected Risk).
|
|
- **Finding**: Detected JA3 mismatch between Camoufox (Chromium) and CurlClient (curl_cffi).
|
|
- Camoufox JA3: `9a9695ad9941a88944c373caf9333b57`
|
|
- CurlClient JA3: `3b0d0e7fc411345ff1917b0325186e26`
|
|
- **Implication**: While Header consistency is achieved, TLS fingerprint identity is not yet perfect. This requires fine-tuning `curl_cffi` impersonation or matching the browser build more closely in Phase 3.
|
|
|
|
## 5. Next Steps
|
|
- Address TLS Mismatch (Phase 3).
|
|
- Implement persistent Redis loops.
