+# 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.
