The cosine-0.87 pairing between the vault's Puckette dataflow bridge note and its Gates-Jevons 'fourth instance / hedged bridge' note is a buried common-ancestor bridge — real, but neither citation-genealogy nor shared-referent, and absent from both the note graph and the tracking hub

Seek's semantic index flagged observation-puckette-dataflow-claims-confirmed-bridge-not-false-friend (2026-08-14) and observation-gates-jevons-fourth-instance-hedged-bridge-pairing-is-citation-genealogy-bridge (2026-08-22) as unlinked neighbors at cosine 0.87 [unverified-quant — needs primary]. Both notes are members of one continuous, explicitly tracked investigative lineage — entity-jingle-fallacy's "bridge-seed check" protocol, applied repeatedly to cosine-flagged unlinked note pairs since the hub's 2026-08-11 first_seen — one sitting near the lineage's origin, the other its most recent stage before this hop.

A direct read against the vault's own established discriminating test — "does either artifact face a live authenticity question that internal evidence resolves?", set by observation-gates-jevons-cosine-pairing-is-embedding-false-friend (and quoted as the operative test by observation-rhw-docsub-gates-jevons-meta-pairing-is-a-hedged-bridge), generalized by this note's source capture to "does a real, checkable connective document exist?" — finds neither of the two bridge species this lineage has already named. It is not citation-genealogy — the species observation-gates-jevons-fourth-instance-hedged-bridge-pairing-is-citation-genealogy-bridge names for its own pair — because neither note wikilinks the other and neither's argument depends on a fact the other established. It is not shared-diagnostic-referent either — the species the 2026-08-22 citation-genealogy note and the hub changelog name for observation-ml-ad-en-gedi-and-gates-jevons-false-friend-notes-are-a-confirmed-bridge's pair — because Max/MSP dataflow semantics and the vault's embedding-false-friend bookkeeping share no entity, document, or date.

Yet the resemblance is not groundless. A real connective document exists: the 2026-08-16 capture that produced observation-ml-ad-en-gedi-and-gates-jevons-false-friend-notes-are-a-confirmed-bridge and updated entity-jingle-fallacy named the Puckette pairing twice in its own body as a member of this same lineage — see the companion finding, observation-2026-08-16-capture-dropped-two-puckette-lineage-mentions-before-promotion, for that evidence in full. Neither mention reached the promoted note or the hub.

The honest classification is a fourth species alongside the lineage's other three: a buried common-ancestor bridge — real, traceable to a specific capture and line, but until this promotion absent from both the note graph and the hub built to track exactly this kind of connection.
