+### 4.1 Performance & Scalability
 - [e.g., Support 10K TPS, scale horizontally to 100 nodes]
 
-### 3.2 Availability & Reliability
+### 4.2 Availability & Reliability
 - [e.g., SLO: 99.9% monthly uptime, MTTR < 10min]
 
-### 3.3 Privacy & Security
+### 4.3 Privacy & Security
 - Data Classification: [e.g., PII, PHI]
 - Threat Model Outcomes: [e.g., "Mitigates replay attacks via nonce + timestamp"]
 - Auth/Z Expectations: [e.g., RBAC with 3 roles: viewer, editor, admin]
 - Encryption: [e.g., TLS 1.3+, AES-256 at rest]
 - Compliance: [e.g., GDPR Art. 32, SOC2 Type II]
 
-### 3.4 Observability & Telemetry
+### 4.4 Observability & Telemetry
 - Required Logs: [e.g., `user_id`, `request_id`, `status`, `latency_ms`]
 - Critical Metrics: [e.g., `auth_failures_total`, `api_latency_seconds{quantile=0.99}`]
 - Tracing: [e.g., Zipkin/B3 propagation, 10% sampling]
 - Alerting: [e.g., `auth_failure_rate > 5%/min` triggers PagerDuty]
 - Retention: [e.g., Logs: 30 days, Metrics: 1 year]
