rate_limiting mitigates rate_limit

Source: Pattern·Target: Failure Mode

Summary

Rate limiting enforced at the API boundary prevents the retry amplification loop that causes rate limit cascades by ensuring callers never exceed the downstream quota in the first place.

Evidence

·rate_limit_cascade lists rate_limiting in affects_patterns; its mitigation is a client-side token bucket that never exceeds the downstream quota (failure_modes/rate_limit_cascade.yaml)
·rate_limiting implements token buckets via Redis INCR + EXPIRE atomic increments (patterns/rate_limiting.yaml)

Evidence grounding

Grounded, 2 supporting items

Client-side token-bucket limiting keeps calls under the downstream quota, preventing rate-limit events.
