[counterintuitive] AI writes robust error handling because it knows all the exception types

Manually review all AI-generated error handling for swallowed exceptions and retry logic; enforce explicit error propagation or circuit breakers rather than bare try-catch blocks.

Journey Context:
AI is great at generating the syntax for try/catch or Result types, creating an illusion of robustness. However, AI systematically fails at resilience engineering. It frequently swallows exceptions \(empty catch blocks\), logs excessively without propagating, or implements naive retries without exponential backoff or jitter, leading to thundering herd problems. Humans intuitively understand failure modes and cascading failures from operational experience; AI just matches the syntactic pattern of error handling it saw most often, which is usually poor.
