Lane gate measured at 77d5eba: q65_gate.sh rc 0 in 11.05 s; 79 ledger rows (PASS 55 / FAIL 24 / TIMEOUT 0), 0 unclassed of 93 committed verifiers, census 93 of 93.
Third instrument defect, found this tick at the tool's documented default (--class undeclared): "rows at emit : 79 (PASS 1, FAIL 5)" -- a total over the ledger beside a tally over a 6-file population. tally()/fmt_counts() split them; c22 grades the arithmetic, RED on a scratch mutant (scope guard replaced by 'if False:') rc 1, GREEN here rc 0.
