+# Subagent 4C: Reliability NFR Assessment
+
+## SUBAGENT CONTEXT
+
+This is an **isolated subagent** running in parallel with other NFR domain assessments.
+
+**Your task:** Assess RELIABILITY NFR domain only.
+
+---
+
+## SUBAGENT TASK
+
+### 1. Reliability Assessment Categories
+
+**A) Error Handling:**
+
+- Try-catch blocks for critical operations
+- Graceful degradation
+- Circuit breakers
+- Retry mechanisms
+
+**B) Monitoring & Observability:**
+
+- Logging implementation
+- Error tracking (Sentry/Datadog)
+- Health check endpoints
+- Alerting systems
+
+**C) Fault Tolerance:**
+
+- Database failover
+- Service redundancy
+- Backup strategies
+- Disaster recovery plan
+
+**D) Uptime & Availability:**
+
+- SLA targets
+- Historical uptime
+- Incident response
+
