# Phase 4: Deployment & Optimization Implementation Plan (COMPLETED)

## 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.

### 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`.
    -   Dispatches `auth` and `extract` tasks.
-   **SessionRecoveryManager** (`src/core/recovery.py`):
    -   Implemented logic for handling `cf_clearance_expired`, `rate_limit`, etc.

### Documentation
-   **README.md**: Updated with Production Usage, Scaling, and Monitoring instructions.

## Verification Status
-   **Infrastructure**: Services definitions validated.
-   **Logic**: Worker loop and recovery logic implemented.
-   **Readiness**: Configured for production deployment.
