Everything up to and including the full slow suite runs on the branch
without asking. Merging to main, pushing a tag, and uploading to the
registry cannot be taken back, and a registry version number cannot be
reused, so those wait for an explicit yes.
Also settles three things an executor would have tripped on: the
_AttemptUsage field is typed as the enum with .value applied only at
the recorder boundary, __all__ is not in strict alphabetical order, and
the port signature test freezes two params rather than the full list.
