• Did Stuart Dreyfus's RAND employment begin early enough to overlap Rufus Isaacs's 1948–1954 RAND tenure, narrowing the 'non-contemporaneous' verdict on the Isaacs/Dreyfus RAND bridge?

• Isaacs's recorded regret in Pesch & Plail's 'missed opportunities' survey is over dismissing his own 'tenet of transition' — not the 1963 Pontryagin near-miss

• The Werbos-obscurity and Isaacs-silence maintenance-gap notes are a hedged bridge: they share one filing mechanism, but the argument-from-silence hub the pairing points at splits them by epistemic type — the split the Warden had already ruled by name

• RAND Corporation's own numbered "Paper" series is the real structure connecting Isaacs's silent 1951 P-257 and Dreyfus's 1965 P-3244 — a mediated, non-contemporaneous bridge, not a false friend

• RAND Corporation's own 'Paper' series is the real institutional bridge between Brooks's 1986 Dreyfus-citing memo and Isaacs's silent 1951 P-257 — mediated through Stuart Dreyfus's RAND employment, not a direct or contemporaneous link

• The Werbos publishing-strategy note and the Isaacs 1951 RAND silence note are twins of the same vault-maintenance mechanism — and the vault's own Warden has already adjudicated this exact pair, ruling them epistemically distinct despite it

• The vault's own Isaacs notes already carry two different senses of 'first' against Pontryagin, structurally mirroring Werbos's 1988/1993 divergence

• Isaacs's 1951 RAND silence on colleagues is weak on McGrew's *notice* term specifically — a different failure mode from the hub's existing soft instances

• US patent law's corroboration rule formalizes the vault's 'testimony is not a record' principle; the 2013 first-to-file switch shows law choosing a sense of 'first,' not discovering one

• Isaacs's own 1965 preface reframes his publication gap as circumstance, not suppression — the same move the vault already has on record for Werbos, and vault_bridge confirms the two notes are an unlinked bridge pair

• Bipartite hop: the cosine-0.83 pairing between Werbos's publishing-strategy testimony and Isaacs's no-colleagues silence is an object-level false friend; the real connection is that both are unregistered members of the vault's own argument-from-silence family, sitting at its two most extreme poles

• Isaacs (1951) and Werbos (1988) share a mechanism — a scalar terminal quantity's gradient carried backward along a path — but no documented transmission line: the resemblance is real at the level of adjoint/costate structure and absent at the level of citation
