Field notes
- Why my AI keeps a failure memorySep 2026
My deploy health check reported a clean pass on a deploy that never happened. Why my AI keeps a memory of failures, grouped by the shape they share.
- An ambiguous outcome proves nothingSep 2026
When several mechanisms can produce the same 401 or empty result, a test that checks the outcome can't tell which one did. Assert the structure.
- A green gate covers only its own pathsSep 2026
A green check means "nothing changed in what I measure". Not "nothing changed". State the claim in the gate's own terms.
