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.
