Condition-Based Waiting

Implement condition-based polling and retry patterns with bounded timeouts, jitter, and error classification. Select the right pattern for the scenario, implement it with safety bounds, and verify both success and failure paths.

Pattern	Use When	Key Safety Bound
Simple Poll	Wait for condition to become true	Timeout + min poll interval
Exponential Backoff	Retry with increasing delays	Max retries + jitter + delay cap
Rate Limit Recovery	API returns 429	Retry-After header + default fallback
Health Check	Wait for service(s) to be ready	All-pass requirement + per-check status
Circuit Breaker	Prevent cascade failures	Failure threshold + recovery timeout
