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.
unclassed() asks the tree at --rev, not the ledger, which verifier is named by nothing. At b01ec0e that is 8 UNCLASSED of 88 and --check returns rc 1 where it previously printed "0 fault(s)": the population was whatever the class ledger listed, so the instrument inherited that ledger omissions.
Also: emit() wrote "rev: HEAD". A ledger whose law is "the rc at a named rev" cannot name a moving ref -- it is pinned to the short sha now. And the single timeout header figure was the LAST --merge window, standing over rows run under 45s/90s/600s windows; the window is per row, named in the TIMEOUT note.
Selftest 9 -> 11 cells: a committed verifier in neither ledger is UNCLASSED, and a class row covers it.
