    CI/CD Pipeline             GitOps Agent (ArgoCD/Flux)
    - Validate                 - Sync configs
    - Test                     - Apply changes
    - Generate                 - Monitor drift
    - Publish
```

### Flujo de Cambios Controlado

```
1. PROPUESTA DE CAMBIO
   Developer → PR con cambios en catalog.toml

2. VALIDACIÓN AUTOMÁTICA
   ├─ Schema validation
   ├─ Dependency analysis
   ├─ Security scanning
   ├─ Generate preview outputs
   └─ Run integration tests

3. REVISIÓN HUMANA
   Code review + deployment review

4. MERGE Y PUBLICACIÓN
   Merge a main → trigger CI/CD

5. GENERACIÓN
   ├─ Generate Docker images
   ├─ Generate K8s manifests
   ├─ Generate Terraform code
   └─ Generate KCL schemas

6. DEPLOYMENT AUTOMÁTICO
   ArgoCD/Flux sync a:
   ├─ Staging (auto)
   ├─ Production (manual approval)
   └─ Multi-region (canary)
```

```

### Validación de Cambios Cross-Project

```rust
// En provisioning/src/orchestrator.rs

pub struct OrchestratorValidator;

impl OrchestratorValidator {
    /// Validar cambios en dependencies globales
    pub async fn validate_cross_project_impact(
        &self,
        changed_service: &Service,
        registry: &ServiceRegistry,
    ) -> Result<CrossProjectImpact> {
        let affected_projects = registry
            .find_consumers(changed_service.id())
            .await?;

        let mut impact = CrossProjectImpact::new();

        for project in affected_projects {
            // Check version compatibility
            if !self.check_version_compat(changed_service, &project)? {
                impact.add_breaking_change(project);
            }

            // Check dependency graph
            if self.would_create_cycle(&changed_service, &project)? {
                impact.add_circular_dependency(project);
            }

            // Check SLA compliance
            if !self.check_sla_impact(changed_service, &project)? {
                impact.add_sla_violation(project);
            }
        }

        Ok(impact)
    }

    /// Notificar affected projects
    pub async fn notify_affected_projects(
        &self,
        impact: &CrossProjectImpact,
    ) -> Result<()> {
        for (project, issues) in impact.iter() {
            // Send notification to project owners
            self.notify_slack(
                &format!("⚠️ Service change impacts {}: {:?}",
                    project.name, issues)
            ).await?;

            // Create automatic issue in project
            self.create_github_issue(project, issues).await?;
        }
        Ok(())

## 🚨 Disaster Recovery

### Estrategia de Recuperación

```
ESCENARIO 1: Service Definition Corrupted
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Detection: Validation pipeline fails
├─ Automatic rollback of commit
├─ Revert PR automatically
├─ Notify team on Slack
└─ Create incident

Recovery: 30 seconds
├─ Last known good state restored
├─ Previous manifests still deployed
├─ No downtime

---

ESCENARIO 2: Breaking Change Not Caught
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Detection: Project fails integration tests
├─ Pre-deployment checks catch it
├─ Automatic canary rollback (5% traffic)
├─ Full rollback if P99 latency increases
└─ Incident auto-created

Prevention:
├─ Cross-project validation (before deploy)
├─ SLA monitoring (during canary)
├─ Automated rollback thresholds

---

ESCENARIO 3: Infrastructure Failure
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Detection: KCL cluster schema fails
├─ Terraform apply fails validation
├─ No deployment attempted
├─ Configuration stays in valid state

Recovery: Manual remediation
├─ Infrastructure team alerted
├─ Re-generate KCL from service definitions
├─ Terraform plan reviewed
└─ Apply with approval

---

ESCENARIO 4: Accidental Service Deletion
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Detection: CI validates missing service is in use
├─ Validation fails (service required but not in registry)
├─ Commit cannot merge
└─ PR blocked until restored

Recovery:
├─ Git history shows deleted service definition
├─ Restore from last commit
├─ Re-validate dependencies
└─ Redeploy
```

### Backup y Versionado

```
Git Repository (Auto-backed up)
├─ services/catalog.toml (all history)
├─ projects/*/services.toml (all history)
├─ infrastructure/*.k (all history)
└─ Tags: v1.0.0, v1.1.0, etc. (releases)

Artifact Repository (Docker Registry)
├─ syntaxis/syntaxis-api:v2.1.0
├─ syntaxis/syntaxis-api:v2.0.0 (previous)
├─ syntaxis/syntaxis-api:v1.9.0 (previous)
└─ Latest: syntaxis/syntaxis-api:latest

Kubernetes (etcd backup)
├─ Daily snapshots
├─ 30-day retention
└─ Cross-region replication

Disaster Recovery SLA
├─ RTO (Recovery Time Objective): < 1 hour
├─ RPO (Recovery Point Objective): < 5 minutes
└─ Backup test: Weekly
```
