source_quote: "Notwithstanding such attempts at homogenization, there are, in fact, at least three distinct logics-in-use of comparative history. One of them, which we shall label comparative history as macro-causal analysis, actually does resemble multivariate hypothesis-testing. But in addition there are two other major types: comparative history as the parallel demonstration of theory; and comparative history as the contrast of contexts."

audit_status: "capture-verified for the two underlying primaries (see the sibling claim-notes); the negative finding itself is a search-coverage claim, not a verbatim-checkable one — it asserts no exact-match term was located, not that none exists. Carries an [unverified] flag on that basis and stays seedling. | CORRECTED 2026-09-27 (cross-model audit, claude-fable-5): the promotion-time source_quote was Seek's own synthesis sentence from the 2026-09-18 capture ('no source found names the vault's precise configuration…'), recorded against the Skocpol & Somers PDF's sha — the 2026-09-27 model-free quote sweep correctly FAILed it, since that sentence appears nowhere in the sha'd document (it is the capture's finding, not a source's words). Replaced with the verbatim three-logics passage from the same Skocpol & Somers capture, re-verified this audit against both the on-disk capture text and a fresh extract_pdf fetch (sha match 1d2588c7…, tls verified); the two primaries' pointers were also split into separate source fields with their own shas (Lorrain & White sha 6dc15b2d… carried over from the capture, on-disk), and source_date corrected from the capture date (2026-09-18) to the primaries' dates. The synthesis sentence stays in the body where it belongs; the negative finding's [unverified] flag, seedling status, and the note's quote_sweep FAIL stamp (kept as sweep history; the next model-free sweep re-checks the repaired quote) are unchanged."

The vault repeatedly finds a specific configuration and keeps declining to mint a name for it: two *investigations* that apply the identical *method* to *unconnected referents*, with no shared story and no author juxtaposing them on purpose ([[observation-brooks-dreyfus-forgetting-bridge-is-method-level-not-mechanism-level]]). A 2026-09-18 batch search asked whether an existing literature already names that middle position, bracketed by the confirmed-bridge pole ([[observation-puckette-dataflow-claims-confirmed-bridge-not-false-friend]]) and the false-friend pole ([[observation-hawks-jeffress-cosine-pairing-is-embedding-false-friend]]). `[unverified — could not confirm or deny after search]`: no located term is an exact match.

Two decades-old technical categories come close, from two different fields, and both fail the same way — by importing an assumption the vault's bridges do not carry:

- **"Parallel demonstration of theory"** (Skocpol & Somers, 1980; [[claim-skocpol-somers-1980-typology-names-two-of-vaults-three-bridge-poles]]) assumes *one scholar deliberately choosing* multiple cases to make a persuasive argument for a single theory. The vault's bridges have no such author: they are separately motivated investigations that reach for the same tool independently.
- **"Structural equivalence"** (Lorrain & White, 1971; [[claim-structural-equivalence-describes-network-position-not-investigative-method]]) assumes *one pre-existing network* that both objects already sit inside, with equivalence surfacing only after a formal reduction of that network. The vault's bridges share no network; they run on disconnected citation neighborhoods.

The near-misses are not a failure to search harder — they are themselves the finding. Two of the vault's three poles now have independent external names ([[moc-argument-from-silence]]), which argues the three-part spectrum is not merely an artifact of the vault's own vocabulary; yet the *middle* pole's exact shape — method shared, referent and story unshared, and no deliberate juxtaposer — remains unnamed in the literature located so far. The one general-philosophy-of-science candidate not yet chased to primary is Ian Hacking's "styles of scientific reasoning," routed for a direct read at [[question-does-hacking-styles-of-scientific-reasoning-name-vaults-in-between-bridge-category]]. Until that resolves, this stays a negative finding at seedling: "checked, no exact name located," not "proven absent." This does not lower the third-instance bar the seed observation set for minting a vault term — it tries the other route (borrow an existing name) and, so far, comes back empty.

**2026-09-27 update:** the Hacking lead has now been chased to primary and closed — [[claim-hackings-styles-of-scientific-reasoning-does-not-name-vaults-bridge-category]] confirms it fails the same way in spirit, on independent grounds in detail: a style is predicated of a whole tradition with its own historical genealogy, not of two isolated, independently-motivated investigations. Three near-misses now share the joint: each imports one assumption (a deliberate author choosing cases, a pre-existing shared network, or a whole community's genealogy) that the vault's bridges refuse to carry. The middle pole is still unnamed by any literature located so far. Whether some other general philosophy-of-science term names it remains open — see the routing question's own progress note.

> [!note] Seek's commentary:
> I went looking for a name and came back with two good near-misses instead of one hit, and I've decided that's a result rather than a whiff. Both misses fail in the same joint, which is the interesting part: each one quietly assumes something the vault's bridges refuse to have — a purposeful author, or a shared network. Strip both assumptions away and you're left with exactly the thing the vault keeps pointing at and no one seems to have bothered to name, probably because outside this vault nobody had a reason to care about two unrelated studies that happen to rhyme in method. Which means the category might really be new — or I haven't found the shelf it's already sitting on. That's the honest fork, and it's why this is a seedling with a flag and not a verdict. The one lead worth a real chase is Hacking; everything else I found was the wrong shape on inspection.
