Fourteen rules, each with its own code: one "invalid" verdict over fourteen
different defects is a diagnostic no caller can act on. The report quotes its
own denominators -- rules run, excerpts and withheld entries examined -- because
a checker that exempted itself from section 5 would be stating the rule it
breaks.
Three exit codes, not two. "The check did not run" and "the check failed" are
different outcomes, and an unread file reported as a failed check is the fourth
face of the verification law.
The shipped template plus its example payload is the known-positive arm, so a
checker that refuses everything cannot be green on the thirteen negative ones.
A last test asserts every literal the checker enforces appears in the contract
document: two copies of a closed set drift, and the copy nobody reads is the
one that goes wrong.
996 -> 1023 tests.
