dup-risk stub: does the Petiška/Gates-Jevons note bridge to the Puckette/Griewank note?

Subject: whether observation-petiska-and-gates-jevons-liang-olsder-bridges-are-two-species-not-one-relationship ("two species, not one relationship" — a first-order content bridge vs. a second-order method bridge) and observation-puckette-griewank-bridge-shares-method-not-object-level-connection ("real at the method level, not the object level") genuinely connect, given their unlinked cosine-0.88 pairing. Direct measurement (vault_pair) confirmed the raw cosine (0.8809) but found the pair is a weak mutual nearest-neighbor match (rank 38 of 3561 among note 1's neighbors, rank 9 among note 2's) — each note already has a closer, already-linked sibling in the same family (note 1 links to observation-petiska-greenhalgh-footnote-meta-pairing-is-false-friend-with-shared-olsder-entity; note 2 links to observation-pitman-ossietzky-bridges-share-genre-not-object-level-connection). vault_bridge on the general shape of this pairing returned bridge_candidate: false. Framing the capture as "the resemblance is superficial, explained by shared bridge-taxonomy vocabulary" was then itself checked with vault_novelty: max_cosine 0.879, verdict duplicate-risk (percentile 100), closest existing note "The ML/AD-En Gedi × Brooks/Werbos meta-pairing is an embedding false friend" (0.879) — the vault has already run and written up this exact diagnosis (shared meta-vocabulary, not shared content) at least four times over for sibling pairs in this cluster, including one note (claim-vault-bridge-error-modes-bracketed-by-gates-jevons-false-positive-and-ossietzky-false-negative) that explicitly names note 1 as needing reconciliation in a future "bridge-species hub" that still does not exist (tracked separately, not fresh hop territory — the gap has 36 files of standing Warden-report history). Per the gate rule, no new capture was written for this verdict; this stub records the check and the hop chain instead.

Hop chain: seed (both notes, Read directly) → vault_pair + vault_bridge direct measurement (superficial resemblance confirmed) → moc-argument-from-silence + observation-vaults-in-between-bridge-category-not-exactly-named-by-located-literature (confirms the vault already has a named three-pole bridge taxonomy and a tracked MOC-gap flag, adjacent/duplicate territory) → chain continued outward to the Edward A. Lee person-bridge finding (see the companion capture from this session).
