The myth-linnainmaa-uncited-before-2010s and claim-nguyen-eger-no-baseline notes are a genuine bridge, but a mediated one — connected through two already-promoted intervening notes, not directly

An embedding-retrieval pairing (cosine 0.84, no shared vocabulary) linked myth-linnainmaa-uncited-before-2010s to claim-nguyen-eger-did-not-measure-linnainmaas-field-so-no-baseline-for-joint-test. Checked directly against both notes, the resemblance is not a false friend: both sit on the same open evidentiary question — whether Linnainmaa's documented post-2010 citation surge is better explained by generic field growth in applied automatic differentiation, or by a backprop-priority-dispute-driven re-reading of his work, the question the myth ledger's "vindicated... 5:1" verdict turns on.

The two seed notes are not directly linked, however. The test connecting them was already run one hop away, by two notes dated 2026-10-16 and 2026-10-24: claim-linnainmaa-post-2010-citers-mostly-generic-ad-not-priority-historiography, which reads Linnainmaa's citing-paper titles directly and finds them dominated by generic applied-AD papers with no connection to the priority dispute, and observation-linnainmaa-citation-growth-underperforms-field-growth-nguyen-eger-bridge, which computes that Linnainmaa's citation-rate growth (≈4.1×) underperforms Nguyen & Eger's measured AI-subfield growth (20–32×) by a factor of roughly five to eight. The bridge the embedding geometry found is real; it runs through these two intervening, already-promoted notes rather than being a fresh discovery of this specific pairing.

This verdict also surfaced a gap: as of this note's writing, myth-linnainmaa-uncited-before-2010s's own status history and Receipts list predate both intervening notes by three and a half months and do not reference them — recorded and addressed in the myth note's own status history, append-only, the same session this note was written.
