The Kodosky/Dennis MOC-indexing note and the Aikins/Jevons record-grading note are a cosine-0.88 embedding false friend — shared vocabulary, not a shared claim

A cosine-0.88, unlinked pairing proposed a bridge between observation-kodosky-dennis-untagged-unindexed-argument-from-silence-instance and claim-aikins-silence-on-jevons-logic-piano-is-weak-on-mcgrew-record-term-not-notice. Read on their own terms, the two notes answer different questions. The Kodosky/Dennis note is a pure vault-hygiene audit — frontmatter tags and moc-argument-from-silence cluster-list membership for claim-kodosky-hopl-reference-list-omits-dennis-citation-unverified-mechanism — and never mentions McGrew's notice/record/survive product. The Aikins/Jevons note is a pure content-grading judgment about which McGrew term is weak in an 1902 textbook's silence, and never mentions frontmatter tags or MOC membership. Neither note's text references the other's actual subject; the 0.88 similarity is best explained by shared high-frequency vocabulary (McGrew, moc-argument-from-silence, "record," negative-citation grading language) rather than a shared claim.

The one axis the two notes literally do share — tagged vs. listed in the hub — confirms rather than undercuts the false-friend verdict: as of 2026-10-24 the two subjects sit at opposite points on it. claim-kodosky-hopl-reference-list-omits-dennis-citation-unverified-mechanism still lacks the argument-from-silence/negative-citation tags (owed to 30-notes/ work per the hub's 2026-09-09 and 2026-10-12 maintenance changelogs) but has been listed in the hub's findings since 2026-09-09. The Aikins/Jevons claim-note carries the correct tag already but, per observation-aikins-jevons-silence-missing-from-argument-from-silence-moc-cluster, has never been folded into the hub's list at all. Each note is half-indexed, on the opposite half — evidence the embedding match is tracking "both are about the vault's own indexing completeness, in some sense," not a specific fact either one states.
