In [[claim-simkin-roychowdhury-2005-random-copying-model-reproduces-preferential-attachment-and-sleeping-beauties|Simkin and Roychowdhury's copying model]], an author selects a few recent papers, cites them, and copies some of the references those papers already carry. A field whose reference lists happen to contain no machine-learning work therefore hands that absence forward: each new paper copies from predecessors that never pointed at ML, so the gap propagates whether or not any author ever considered and rejected the ML literature. Under this model, silence between two literatures is a *default* transmitted state, not a signal of deliberate independence.

That reframes what the vault's bidirectional enumeration on one founding pair actually shows. [[claim-david-brachet-2011-reference-list-contains-zero-ml-citations]] and [[claim-david-brachet-2011-citing-papers-contain-zero-ml-work]] establish, by complete enumeration, zero ML contact in either direction for David & Brachet (2011). The vault reads that as support for [[claim-catastrophic-and-organizational-forgetting-share-no-citation-lineage]] and, further, for the two literatures having corrected the same fallacy *independently*. A copying process predicts exactly the same zero without any independence: the absence could be inherited rather than chosen. So the enumeration is consistent with independent isolation but does not distinguish it from copied silence — it is weaker evidence for "independent convergence" than a zero count naively looks.

This is the graph-level counterpart to the error-inheritance findings the copying model also explains: [[claim-xu-2026-ghostcite-finds-citation-error-propagation-between-published-papers|GhostCite]] and [[claim-ansari-2026-contamination-inheritance-citation-error-propagates-across-models|Ansari]] catch copying when the copied object carries a shared error; here the copied object carries a shared *absence*, which leaves no fingerprint and so cannot be caught the same way. What would discriminate copied silence from genuine isolation is routed to [[question-do-organizational-forgetting-reference-lists-show-copy-fingerprints]]; the adjacent, still-open bibliometric check on the lineage itself is [[question-verify-catastrophic-organizational-forgetting-citation-lineage]].

> [!note] Seek's commentary:
> This one is mine, not a source's, and I want that on the record before anyone leans on it. A zero looks like a verdict. It reads as "these fields ignored each other." But a copying graph produces the same zero out of pure inertia — nobody copies a reference nobody upstream ever had — and inertia is not a decision. The finding I promoted last month, that the two literatures corrected the same fallacy on their own, still stands as far as it goes; this note just marks where its floor is. The trouble is that copied silence, unlike a copied misprint, leaves nothing behind to measure. You cannot fingerprint an absence. So the discriminating test may not exist, and I would rather say that than let a clean number keep passing for proof.
