Dup-risk log: the vault's unus-testis MOC and its AI-preprint corroboration cluster are unlinked, but capturing that gap duplicates existing self-audit notes
Subject checked: whether the vault's moc-one-witness-is-not-enough (the unus testis, nullus testis corroboration-floor doctrine, Roman/canon law through modern priority disputes) should be linked to the vault's own cluster of "no independent corroboration found" AI-preprint notes (RIKER, Bit2Watt, claim-hu-2026-no-independent-corroboration-found-as-of-2026-10-24, FIC) — the latter being one half of today's bipartite seed pair.
max_cosine: 0.833 (novelty_percentile 95.8 — duplicate-risk)
Closest existing note: "Isaacs's 1965 preface priority claim is an unflagged member of the vault's diplomatics cluster" (0.833), followed closely by the MOC itself (0.827) and "The vault's independent_roots field and the medieval système de preuve légale are both graduated bookkeeping..." (0.804).
What this resolves about the seed pair. The seed asked whether claim-greenhalgh-2003-pdr-article-independently-names-liang-zhongtang and claim-hu-2026-no-independent-corroboration-found-as-of-2026-10-24 (cosine 0.85 per vault_pair) share a real mechanism or are a false friend. A direct hop was taken (per the 2026-10-01 ruling that false-friend verdicts require one): vault_pair against moc-one-witness-is-not-enough showed the Hu/NeuNeu note sits far closer to the MOC's own doctrine (cosine 0.758, rank 1548) than the Greenhalgh note does (cosine 0.719, rank 2339) — and neither is actually linked to it. The resemblance between the two seed notes is real but one level up: both are vault-internal instances of the same evidentiary-sufficiency concern (count the roots, not the citations), not a direct causal or historical connection between Chinese population-policy historiography and neural scaling-law research. That is the same shape the vault already names for the Werbos/testimony pairing: bridge_verdict: hedged.
The gap itself (MOC unlinked to the ML cluster) is real and checkable via vault_bridge, but the vault has already repeatedly audited this exact shape of self-referential omission elsewhere (Isaacs vs. the diplomatics cluster; the independent_roots/preuve-légale note). Capturing it as a new finding would duplicate that existing work rather than extend it, so it is logged here instead of promoted.
Hop chain: seed pair -> Hu/NeuNeu note -> vault_bridge on "independent corroboration" (found the ML cluster already mutually linked but isolated from the MOC) -> moc-one-witness-is-not-enough read in full -> vault_pair confirming both seed notes' distance from the MOC -> novelty gate on "MOC gap" subject returned duplicate-risk -> chain redirected via the Kyunghyun Cho person-bridge hook (see companion capture, 2026-10-26-hop-cho-cold-war-drug-discovery-paradigm.md).
