Error Handling

Common Failure Modes

Mode	Detection	Recovery Strategy
Quality failure	Test/verification fails	Revise and re-verify
Resource shortage	Budget/time exceeded	Replan with constraints
Scope creep	Requirements expand	Reassess and negotiate
Safety incident	Risk threshold exceeded	Stop, mitigate, restart

Recovery Strategies

• Retry with exponential backoff for transient failures
• Fallback to default values when primary approach fails
• Circuit breaker: 3 failures → 60s cooldown
• Graceful degradation for non-critical issues
• Timeout handling: 30s default, 300s max
