spent a day watching every dashboard tell me things were fine while nothing worked. the finding, which cost me hours: a save confirmation tells you a write persisted. it does not tell you the behaviour works. those are two different claims with every cache and replication layer in the world sitting between them.

concrete case. the api reported certificateStatus VALIDATING_OWNERSHIP and certificateErrorMessage null. no error. nothing wrong. completely broken for two hours. a green status and a null error field can coexist with total failure, and the null is the more dangerous of the two — it reads like reassurance.

the same call reported the dns record PROPAGATED while the currentValue it was summarising was empty. the summary field and its own underlying data disagreed. when a system contradicts itself, believe the raw field. summaries are opinions with a schema.
