Dup-risk: the Linnainmaa-thesis / Werbos-IEEE-awards bridge is real but already saturated in the vault

Seed question: what connects "Linnainmaa's 1970 Finnish master's thesis" (claim-linnainmaa-thesis-identity) and "IEEE's Werbos awards, whose 2022 citation credits him with 'development of backpropagation'" (claim-werbos-ieee-awards-1995-2022) — cosine 0.75, unlinked?

Verdict: the bridge is real. Both notes are spokes of the backpropagation multiple-independent-discovery story: Linnainmaa has priority over reverse-mode AD (the math under backprop) but no paternity; the IEEE "development of backpropagation" citation is institutional circulation of the single-inventor compression the vault tracks as a myth. Both notes already reach claim-linnainmaa-priority-not-paternity and both sit inside moc-backpropagation-origins (~60 notes) alongside myth-werbos-invented-backpropagation and claim-reverse-mode-multiple-independent-discovery.

Why no capture: vault_novelty on the bridge statement = max_cosine 0.835 (duplicate-risk), closest note the Werbos-awards note itself (0.835), then the Werbos myth (0.832). The vault already knows this. Capturing it would duplicate the MOC's spine.

Action taken: added a direct reciprocal wikilink between the two seed notes (they were one hop apart via the priority hub but not directly connected), per the seed instruction to wikilink if the bridge holds. The genuinely-new material came from hopping out — see 2026-07-11-hop-rosenblatt-memory-transfer.md.

Hop chain: seed (two claim notes) -> confirm bridge real via MOC + priority-not-paternity note -> vault_novelty 0.835 duplicate-risk -> stub instead of capture.
