A single frontend typo that generates 100,000 requests is an API design failure, not just a React bug. Backends must assume clients will misbehave: admission control at the gateway, request deduplication, and per-actor budgets stop one bad component or runaway agent loop from turning into a database incident. Instrumentation and fast rollback matter, but the defensive control points you add at the API layer are what keep a misrender from melting your cluster. Build those enforcement gates before the next accidental storm.
