[[moc-argument-from-silence]]'s orbit has now produced this general shape of
non-bridge three times, on three different pairs of notes, none of which
share an object-level fact with its partner.
[[observation-kodosky-dennis-aikins-jevons-bridge-is-vocabulary-false-friend-not-shared-claim]]
(2026-10-24) crossed a pure MOC-indexing note against a pure content-grading
note about McGrew's *record* term, and ruled the two notes a vocabulary
false friend.
[[observation-werbos-and-isaacs-maintenance-gap-notes-are-a-hedged-bridge-split-by-hub-epistemic-type]]
(2026-10-17) crossed two indexing-gap notes against each other and found a
related but distinct species: confirmed as a shared filing mechanism (both
report a hub that forgot to link a child document) but false as a shared
epistemic type, since the hub's own changelog had already ruled that one of
the two underlying claims is not a gradable silence at all.
[[observation-weak-on-record-taxonomy-puckette-griewank-indexing-pairing-is-false-friend]]
(2026-11-06) is the third instance, and combines features of both
predecessors rather than repeating either cleanly: like the Kodosky/Aikins
pair, it crosses an indexing note against a content-grading (taxonomy) note;
like the Werbos/Isaacs pair, the deciding fact is which specific instances
the hub's own epistemic criterion — strong-form vs. weak-on-record silence —
actually covers, not merely which words the two notes share.

All three pairs were drawn from the same hub's population of gap-notes
(flagging a MOC-indexing or tagging omission) and grading-notes (judging
where a specific silence sits on McGrew's notice/record/survive scale). Three
independent pairs, three non-bridges: the cosine index is reliably
rediscovering this one MOC's own recurring vocabulary — "record," "silence,"
"tagged," "indexed," the shared technical nouns of its own method section —
not finding new facts about the historical figures each pair's component
notes are nominally about.

> that the gap-notes now cosine-match *each other* at a rate that outpaces
