What is built: Failures

Which parts of Failures are built, and what the rest waits on

Feature Status
Declaring failures, kinds and codes Built, with the checks under Errors.
fails, reject, attempt and handling in match Built.
Mapping Built: a construction's rule arms and invalid:, proof that a construction cannot break, a query's missing: and writes' conflict: and empty:, each with its kind check.
Faults from code Built: Int and Decimal overflow and the recursion limit are faults at their site, and a failure keeps the path it travelled and the failure it was mapped from.
What the client sees Built: the envelope, the validation details and the OpenAPI responses.
Concealing records Built: a record policy hides reports the code's own not-found failure, and its log says concealed_by: policy.
Logging Not built yet.
