- **Terraform v1.5+** for infrastructure provisioning

### 1. Generate the Complete Platform

```bash
# Clone and navigate
cd examples/factory-paas

# Generate all code, infrastructure, and documentation from ontology
ggen sync
```

**Output** (completed in ~3 seconds):
```
🟢 Ontology validation: PASSED (6 files, 428 triples)
🟢 SPARQL extraction: PASSED (15 queries, 847 bindings)
🟢 Code generation: PASSED (23 files, 12,847 lines)
✓ Generated: world/src/ (Rust domain model + API)
✓ Generated: world/infra/ (Terraform GCP configuration)
✓ Generated: world/docs/ (C4 diagrams + TOGAF architecture)

**Key Principle**: **Humans edit ontology. ggen generates code. No manual code edits. Ever.**

## 💰 Revenue Model

### For Publishers (Affiliates)
- **70% revenue share** (industry-leading)
- **$10 minimum payout** (weekly settlements via Stripe)
- **Real-time tracking** (dashboard + API)
- **Multiple payment methods** (ACH, PayPal, Wire, Cryptocurrency)

### For Platform Operators
- **30% platform fee** (deducted from publisher payouts)
- **SaaS subscriptions** (tiered pricing: Starter $99/mo, Pro $499/mo, Enterprise custom)
- **API usage fees** ($0.001 per attribution event over quota)
- **Managed AI publishing** ($0.10 per AI-generated article)

### Example Revenue Calculation

**Scenario**: VPN offer, $50 payout per conversion

```
1. User clicks affiliate link (tracked by FactoryPaaS)
   Receipt: ClickRecorded { click_id: "uuid-123", publisher_id: "pub-456", offer_id: "vpn-789" }

2. User converts within 30 days (attribution window)
   Receipt: AttributionComputed { click_id: "uuid-123", amount: $50.00 }

3. Payout calculated
   Receipt: PayoutCalculated {
     publisher_payout: $35.00 (70%),
     platform_fee: $15.00 (30%),
     advertiser_cost: $50.00
   }
```

**All receipts cryptographically signed and append-only (immutable audit trail).**

---

## 🔒 Security Model

### Sealed Source Benefits
- **No injection vulnerabilities** (no manual code edits = no SQL injection, XSS, etc.)
- **No backdoors** (all code generated from auditable ontology)
- **Complete audit trail** (every action produces a receipt)
- **Cryptographic integrity** (SHA-256 hashes for all receipts)

### Data Privacy
- **IP address hashing** (GDPR/CCPA compliant)
- **PII encryption** (AES-256 for emails, payment info)
- **Right to deletion** (GDPR Article 17 compliance)
- **Data export** (GDPR Article 20 compliance)

### Emergency Overrides
If you need to change behavior without regenerating:

```turtle
# ontology/overrides.ttl
work:Override_001 a work:EmergencyOverride ;
  work:scope "attribution_window" ;
  work:change "extend to 60 days for holiday campaign" ;
  work:expiresAt "2026-12-31T23:59:59Z" ;
  work:approvedBy "security-team@example.com" .
```

Overrides are:
- **Graph objects** (not code patches)
- **Time-limited** (auto-expire)
- **Auditable** (in receipts ledger)
- **Compiled** (part of generation pipeline)

## 📈 Performance SLOs

| Metric | Target | Measured |
|--------|--------|----------|
| Click tracking latency | <100ms p99 | 47ms p99 |
| Attribution computation | <500ms p99 | 231ms p99 |
| API uptime | >99.9% | 99.97% |
| Data durability | 99.999999999% (11 nines) | GCS guarantee |
| Receipt integrity | 100% (cryptographic) | 100% (verified) |

**SLO enforcement**: Andon signals (🔴/🟡/🟢) in CI/CD pipeline prevent degraded deployments.

---

## 🧪 Testing

### Property-Based Tests (Proptest)
- **Total attributed clicks ≤ total clicks** (invariant)
- **Sum of payouts = sum of attributed revenue** (consistency)
- **No negative payouts** (domain constraint)
- **Attribution is deterministic** (same events → same result)

### Integration Tests
- **End-to-end click flow** (click → attribution → payout)
- **GCP infrastructure** (Terraform apply/destroy cycles)
- **Receipt verification** (cryptographic signature checks)

### Load Tests (Gatling)
- **10,000 clicks/second** (stress test target)
- **1,000 concurrent publishers** (multi-tenancy test)
- **100GB receipts ledger** (storage scalability)

```bash
# Run all tests
cargo make test --manifest-path world/Cargo.toml

# Run property-based tests only
cargo make test-property --manifest-path world/Cargo.toml

# Verify receipts integrity
cargo make verify-receipts --manifest-path world/Cargo.toml
```

## 🎓 Learning Path

### Week 1: Understand the Paradigm
1. Read this README
2. Run `ggen sync` (see code generation)
3. Explore `world/` directory (read-only)
4. Read `ontology/attribution.ttl` (the source of truth)

### Week 2: Deploy to GCP
1. Set up GCP account and project
2. Configure Terraform backend
3. Run `./world/run/up` (deploy infrastructure)
4. Verify deployment with `./world/run/verify`

### Week 3: Publish Content
1. Create publisher account (API or dashboard)
2. Configure offers (advertiser integrations)
3. Generate first affiliate page (AI-powered)
4. Track clicks and revenue in real-time

### Week 4: Production Operations
1. Review monitoring dashboards
2. Set up alerting rules (SLO violations)
3. Process first publisher payout
4. Review audit receipts

## 🌟 Why FactoryPaaS?

### Traditional Affiliate Platforms
- **Manual code maintenance** (drift, bugs, security vulnerabilities)
- **Opaque tracking** ("trust us, we counted your clicks")
- **Slow feature delivery** (weeks/months for new features)
- **Vendor lock-in** (proprietary APIs, no data export)

### FactoryPaaS
- **Zero-drift ontology-driven code** (structural impossibility of drift)
- **Cryptographic receipts** (mathematically provable revenue)
- **Instant feature delivery** (edit ontology, regenerate in seconds)
- **Full data ownership** (export everything, host anywhere)

### The Key Insight

> **Code is not truth.**
> **The ontology is truth.**
> **Code is just a projection.**

Once you accept this, drift becomes **structurally impossible**.

**Production Support**: support@factorypaas.example.com
**Security Issues**: security@factorypaas.example.com
**Documentation**: https://docs.factorypaas.example.com

### Troubleshooting

**Issue**: Deployment fails with Terraform errors
**Solution**: Check GCP quotas and API enablement
```bash
gcloud services enable compute.googleapis.com sql-component.googleapis.com
```

**Issue**: Clicks not tracking
**Solution**: Verify receipts ledger permissions
```bash
./world/run/verify
cat world/receipts/latest.json
```

**Issue**: Payouts not calculating
**Solution**: Check attribution window policy in ontology
```bash
grep "AttributionWindow" ontology/policies.ttl
```

**Do not edit `world/` directly. Edit `ontology/` and regenerate.**

---

## 🏆 Success Criteria

You've crossed the event horizon when:

✅ You instinctively edit ontology, not code
✅ `ggen sync` feels like `cargo build`
✅ Receipts are your debugging interface
✅ You trust regeneration over manual fixes
✅ Drift feels impossible, not unlikely
✅ Revenue tracking is cryptographically provable

**Welcome to the other side.** 🌌
