🏗️ System Architecture

Request Flow (Streaming)

Client Application
    ↓ HTTP POST with stream: true
Client Proxy (localhost:3000)
    ↓ SSE passthrough (z  # Windows: venv\Scripts\activate
pip install -r requirements.txt

# Start dependencies
docker-compose -f ../docker-compose.coordinator.yml up -d

# Run database migrations
alembic upgrade head

# Start coordinator
uvicorn main:app --host 0.0.0.0 --port 8000

2. Start Worker (Requires GPU)

# Ensure Ollama is running
ollama serve

# Build and run worker
cargo run --bin monkey-troop-worker --release

# Worker will:
# - Auto-detect Tailscale IP
# - Start JWT verification proxy on port 8080
# - Send heartbeat to coordinator every 30s
# - Complete PoH benchmark on first registration

3. Start Client

# Run client proxy
cargo run --bin monkey-troop-client --release

# Client starts OpenAI-compatible API on localhost:3000

4. Test End-to-End

Non-streaming request:(Coordinator)

TimeoutMiddleware (outermost layer)
    ↓ 5s/30s/300s timeouts
RequestTracingMiddleware
    ↓ X-Request-ID tracking
RateLimitMiddleware
    ↓ Redis-backed 100/hr, 20/hr
FastAPI Routes
    ↓ Business logic

Database Schema

users (PostgreSQL)

id: Primary key
public_key: RSA public key for identity
balance: Current credit balance (float)
created_at: Account creation timestamp

transactions (PostgreSQL)

id: Primary key
user_id: Foreign key to users
amount: Credit amount (positive = credit, negative = debit)
transaction_type: "credit" or "debit"
description: Human-readable description
metadata: JSONB for additional details
created_at: Transaction timestamp

audit_logs (PostgreSQL)

id: Primary key
timestamp: Event timestamp (indexed)
event_type: "authorization", "transaction", "rate_limit", "security" (indexed)
user_id: User identifier (indexed, nullable)
ip_address: Client IP address
details: JSONB for flexible event data

Security Architecture

Authentication Flow:

Client requests authorization from coordinator
Coordinator generates JWT with RSA-2048 private key
JWT includes: user_id, target_node, audience, expiration
Worker validates JWT signature using coordinator's public key
Worker forwards request to Ollama if valid

Credit System:

New users receive 1000 starter credits
Authorization checks balance before issuing ticket
Job completion triggers HMAC-SHA256 signed receipt
Coordinator verifies receipt and records transaction
Credits deducted based on: duration × hardware_multiplier

Rate Limiting:

Redis-backed with sliding window algorithm
Default tier: 100 requests/hour
Strict tier: 20 requests/hour (for expensive operations)
Per-IP enforcement with X-Forwarded-For support

🚀 Getting Started

Prerequisites

Rust 1.75 or later
Python 3.11 or later
PostgreSQL 15+
Redis 7+
Docker and Docker Compose (optional)
Ollama (for worker nodes)

Environment Setup

Copy environment template:

cp .env.example .env
# Edit .env with your configuration

Generate RSA keys:

openssl genrsa -out coordinator_private.pem 2048
```bash
curl -X POST http://localhost:3000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "llama3:8b",
    "messages": [{"role": "user", "content": "Hello!"}],
    "stream": false
  }'

Streaming request (Server-Sent Events):

import requests

response = requests.post(
    "http://localhost:3000/v1/chat/completions",
    json={
        "model": "llama3:8b",
        "messages": [{"role": "user", "content": "Write a story"}],
        "stream": True
    },
    stream=True
)

for chunk in response.iter_lines():
    if chunk:
        print(chunk.decode('utf-8'))

Database Management

Run migrations:

cd coordinator
alembic upgrade head  # Apply all pending migrations

Rollback migration:

- ✅ RSA-2048 JWT signing and verification
- ✅ Circuit breaker pattern for fault tolerance
- ✅ Retry logic with exponential backoff
- ✅ PostgreSQL credit ledger with transactions table
- ✅ Starter credits (1000.0) on first authorization
- ✅ HMAC-SHA256 receipt verification
- ✅ Transaction history endpoint
- ✅ Redis-backed rate limiting (100/hr, 20/hr)
- ✅ Sliding window rate limit algorithm
- ✅ Rate limit violation logging
-  🐛 Known Issues & Limitations

### Resolved Issues ✅

1. **HTTP Version Mismatch** ✅ FIXED
   - **Problem**: Reqwest uses `http` 0.2, axum uses `http` 1.x
   - **Solution**: Manual status code conversion with `.as_u16()`

2. **Blocking Calls in Async Context** ✅ FIXED
   - **Problem**: Engine drivers used `reqwest::blocking` in async functions
   - **Solution**: Migrated to async reqwest with tokio

3. **Streaming Support** ✅ IMPLEMENTED
   - **Problem**: Client and Worker didn't handle SSE streaming
   - **Solution**: Zero-copy passthrough with `Body::from_stream()`

### Minor Issues (Non-blocking)

4. **Unused Import Warnings**
   - Some test files have unused imports
   - Fix: `cargo fix --test "integration_test"`
   - Impact: Cosmetic only, tests pass

5. **Mypy Type Hints**
   - Python type checking set to continue-on-error
   - Some functions lack complete type annotations
   - Impact: No runtime effect

6. **No Testcontainers**
   - Integration tests don't use embedded Docker containers
   - Tests require manual PostgreSQL + Redis setup
   - Impact: CI/CD handles service setup automatically

### Out of Scope

7. **VPS Deployment**
   - Not implemented per user requirements
   - Handled separately from codebase
   - CI/CD has deployment stubs as placeholders

## 🎯 Success Criteria - All Met ✅

**Files**:
- `coordinator/tests/test_integration.py`: Full authorization + inference flow
- `coordinator/tests/test_transactions.py`: Credit accounting logic
