-# FAEA
+# FAEA: High-Fidelity Autonomous Extraction Agent
 
+## Overview
+FAEA is a hybrid extraction system designed to defeat advanced bot mitigation (Cloudflare, Akamai, etc.) using a "Headless-Plus" architecture. It combines full-browser fidelity (Camoufox/Playwright) for authentication with high-speed clients (curl_cffi) for data extraction.
+
+## Features
+- **Bifurcated Execution**: Browser for Auth, Curl for Extraction.
+- **TLS Fingerprint Alignment**: Browser and Extractor both mimic `Chrome/124`.
+- **Evasion**:
+  - **GhostCursor**: Human-like mouse movements (Bezier curves, Fitts's Law).
+  - **EntropyScheduler**: Jittered request timing (Gaussian + Phase Drift).
+  - **Mobile Proxy Rotation**: Sticky session management.
+- **Production Ready**:
+  - Docker Swarm/Compose scaling.
+  - Redis-backed persistent task queues.
+  - Prometheus/Grafana monitoring.
+
+## Getting Started
+
+### Prerequisites
+- Docker & Docker Compose
+- Redis (optional, included in compose)
+
+### Quick Start (Dev)
+```bash
+docker-compose up --build
+```
+
+## Production Usage
+
+### 1. Scaling the Cluster
+The infrastructure is designed to scale horizontally.
+```bash
+# Scale to 5 Browsers and 20 Extractors
+docker-compose up -d --scale camoufox-pool=5 --scale curl-pool=20
+```
+
+### 2. Monitoring
+Access the dashboards:
+- **Grafana**: `http://localhost:3000` (Default creds: admin/admin)
+- **Prometheus**: `http://localhost:9090`
+- **Metrics**: Authentication Success Rate, Session Duration, Extraction Throughput.
+
+### 3. Task Dispatch configuration
+Tasks are dispatched via Redis `task_queue` list.
+Payload format:
+```json
+{
+  "type": "auth",
+  "url": "https://example.com/login",
+  "session_id": "sess_123"
+}
+```
+
+## Architecture
+
+- `src/browser/`: Camoufox (Firefox/Chrome) manager for auth.
+- `src/extractor/`: Curl Client for high-speed extraction.
+- `src/core/`: Shared logic (Session, Scheduler, Recovery).
+- `src/orchestrator/`: Worker loops and task management.
+
+## Testing
+Run unit tests:
+```bash
+./venv/bin/pytest tests/unit/
+```

-# Phase 4: Deployment & Optimization Implementation Plan
+# Phase 4: Deployment & Optimization Implementation Plan (COMPLETED)
 
 ## Goal Description
-Transition the system from a functional prototype to a scalable, production-ready extraction grid. This involves:
-1.  **Scaling**: Configuring Docker Compose for high concurrency (5 Browsers, 20 Extractors).
-2.  **Resilience**: Implementing persistent task queues and auto-recovery logic.
-3.  **Observability**: Integrating Prometheus metrics for monitoring health and success rates.
+Transition the system from a functional prototype to a scalable, production-ready extraction grid.
 
-## User Review Required
-> [!NOTE]
-> **Monitoring**: We will add `prometheus` and `grafana` containers to `docker-compose.yml` to support the metrics collected by `src/core/monitoring.py`.
-> **Task Loops**: We will introduce a new entry point `src/orchestrator/worker.py` to act as the persistent long-running process consuming from Redis.
