Judge a measurement against the committed baseline.
Four red paths, and they are reported TOGETHER rather than one per run, so a
repo does not fix one number only to discover the next on the following push:
NO_SETS the root manifest lists nothing; a run over nothing is never

REGRESSION fewer sets are minted than the baseline records.
UNDECLARED_RAISE more are minted than the baseline records; crossing
the line is a deliberate act and gets a deliberate edit.
INCOMPLETE a listed set carries no stable ids at all. This is the rule
the vendored ratchet lacked, and the reason a new set could erode the
promise without anything turning red.
