Why go/no-go decisions still run on faith in contracts, and the gap between pipelines that prove correctness and pipelines that produce evidence.

Along with unit and integration tests, we deploy our whole app in CI to ephemeral environments for QA testing. All of them are connected to otel. Test results are persisted to an analytics database. If we wanted go whole hog we could add chaos testing. So I would not say "we forgot to automate it". Am I missing something?
