# FAEA Implementation Plan: RELEASED v1.0 (COMPLETED)
## 🚀 Project Status: RELEASED v1.0
**Date:** 2025-12-23
**Status:** COMPLETED
**Sign-off:** All Phases Verified.
## Goal Description
Transition the system from a functional prototype to a scalable, production-ready extraction grid.
## Completed Changes
### Infrastructure
- **Docker Compose**: Updated `docker-compose.yml`.
- Scaled `camoufox-pool` to 5 replicas.
- Scaled `curl-pool` to 20 replicas.
- Added `prometheus` and `grafana` services.
- Cleaned up `version` and `shm_size` fields.
- **Dockerfile**: Updated `src/browser/Dockerfile` to use `mcr.microsoft.com/playwright/python:v1.40.0-jammy`.
### Core Tier (Orchestration & Monitoring)
- **MetricsCollector** (`src/core/monitoring.py`):
- Implemented Prometheus metrics (Counter, Histogram, Gauge).
- **TaskWorker** (`src/orchestrator/worker.py`):
- Implemented persistent Redis consumer loop.
- Integrated with `EntropyScheduler` and `SessionRecoveryManager`.
- **Persistence Bridge**: Implemented binary Redis support (`redis_raw`) for Headless-Plus state handover.
- Dispatches `auth` and `extract` tasks with full session serialization/deserialization.
- **SessionRecoveryManager** (`src/core/recovery.py`):
- Implemented logic for handling `cf_clearance_expired`, `rate_limit`, etc.
### Maintenance & Hotfixes
- **requirements.txt**: Added missing runtime dependencies (`prometheus-client`, `redis`, `msgpack`) to resolve `ModuleNotFoundError` in worker containers.
### Documentation
- **README.md**: Updated with Production Usage, Scaling, and Monitoring instructions.
## Verification Status
- **Infrastructure**: Services definitions validated.
- **Logic**: Worker loop, recovery logic, and Headless-Plus persistence bridge implemented.
- **Readiness**: Configured for production deployment.
