A “quick fix” introduced a single-AZ dependency nobody documented. Systems fail because resilience is assumed, not proven. I’ll show how AI agents discover hidden dependencies by scanning both infrastructure AND source code — finding hard-coded endpoints with no retry logic, missing circuit breakers, undocumented API calls. Then I’ll show how AI auto-generates targeted chaos experiments from those findings — testing YOUR actual failure modes, not generic disruptions. Leave ready to find and validate your own hidden risks in hours, not weeks.
