MOC: The attribution is not the evidence — documentary source criticism as a domain-general forensic move

One forensic move keeps being reinvented in fields that never cite each other: authenticate an origin-claim by comparing dated primary sources, refusing the received attribution — the document's own self-claim, an award citation's flat "for development of X," a claimant's own memory of being first. Jean Mabillon named it for charters in 1681; a 2011 Federal Circuit rule names it for patents; a NASA letter, a 1975 source-code printout, and two priority-staking prefaces all perform it without ever using the word. This map holds those instances side by side.

What this is, and is not. This is the general map the single-instance moc-testimony-is-not-a-record (Werbos's priority narrative, examined as documents) explicitly points up to and says "does not yet exist." Its parent is moc-attribution-and-origin-myths, which deliberately keeps Mabillon as a neighbor, not a member, leaving this space unmapped on purpose. The hubs for the concept already exist — entity-diplomatics (whose aliases include "documentary source criticism"), entity-quellenkritik, entity-jean-mabillon; what was missing was the argument-level navigation across domains, which is what a MOC is for. The argument is the evidentiary rule (the attribution is not the evidence); the members are its instances; naming the map for the rule rather than for "diplomatics" is the 2026-07-25 lesson — the recurring method is not, by itself, the recurring claim.

The founding move

• claim-mabillon-1681-founded-diplomatics-to-refute-forgery-charge — Mabillon answers a Jesuit's blanket forgery charge against the Church's charters not case by case but with a general, repeatable test: judge authenticity by script, seals, materials, and formula against securely dated exemplars. (Rests on a Tier-3 Wikipedia entry quoting a 1972 translation — the thinnest footing in the cluster, flagged.)
• observation-priority-adjudication-is-documentary-source-criticism — the synthesizing note: adjudicating who discovered X and whether a charter is genuine are, at the level of method, one operation. Merton is the hinge who both theorized the multiple-discovery shape and practiced Mabillon's method on a misattributed aphorism.

The documented-descent leg (history of mathematics)

The one leg entity-diplomatics annotates as direct descent rather than convergence — later historians using dated primaries to settle priority:

• claim-wallis-1685-history-of-algebra-used-documentary-evidence-to-favor-harriot-over-descartes
• claim-raphson-1715-history-of-fluxions-used-newtons-papers-to-assert-priority-over-leibniz

The forgery-forensics species (internal features against a forger's motive)

• claim-coremans-bakelite-in-paint-proved-van-meegeren-vermeers-were-forgeries — a 20th-century binding medium a forger's era-appropriate motive could not have produced.
• claim-thermoluminescence-dating-became-a-commercial-antiquities-forgery-detector — the method industrialized.
• observation-gates-altair-basic-authentication-is-diplomatics-cluster-member — Gates's 2025 Altair-BASIC scan argued genuine (not a reconstruction) from features "a forger would not need to fabricate consistently": a clean cross-page header, consistently garbled OCR of the title, a print-queue banner dated 10-SEP-75. Same move as Mabillon and Coremans, in computing.

The self-testimony species (the claimant's own word, graded)

• observation-isaacs-1965-preface-priority-claim-is-unflagged-diplomatics-cluster-member — Rufus Isaacs staking priority on the dated fact of his own manuscript against the arrival of Pontryagin's book; one telling, nothing yet to triangulate.
• Werbos's whole priority narrative — the deep single-instance audit lives at moc-testimony-is-not-a-record, whose finding is mostly one witness, partly a record. This map carries the instance by pointer, not by re-hosting it.

The chronology species (dating the record against the narrative)

• claim-docsub-episode-postdates-rhw-1986-nature-paper-by-years — anachronism-exclusion: a 1993/1998 account cannot have caused a 1986 paper's content, the same logic that unmasks a feature postdating a charter's claimed era.
• claim-mcpeters-1990-letter-dates-opt-investigation-to-july-1984 — primary-supersedes-secondary: a dated first-person letter overruling a later secondary paraphrase's month, closer to Mabillon's exemplar-comparison than to an anachronism argument.
• observation-docsub-and-mcpeters-are-unflagged-diplomatics-cluster-members and observation-docsub-mcpeters-diplomatics-are-two-species-sharpening-ozone-myth-ledgers-bridge — the notes that establish these two as members and as two distinct species of the one genre.

The legal register (binding doctrine, not a historian's instinct)

• claim-us-patent-law-corroboration-rule-bars-uncorroborated-testimony-of-prior-invention — MPEP §715 / In re NTP (Fed. Cir. 2011): "An inventor cannot rely on uncorroborated testimony to establish a prior invention date." The same finding the vault assembled from prefaces and oral histories, carried as enforceable law. (The first-to-invent frame it belongs to was largely superseded by the 2013 AIA; the corroboration principle is the durable part.)

What is a lineage and what is a convergence

The map's load-bearing honesty: most of these instances are a recurrence of method, not a documented transmission. The founding observation holds the Mabillon → Quellenkritik (Ranke) → modern-priority-scholarship descent as an analogy until documented, routed to question-verify-diplomatics-to-priority-adjudication-descent. The Wallis/Raphson leg is the exception entity-diplomatics annotates as genuine descent. The cross-domain members (ozone, computing, patent law) almost certainly reinvented the move independently — which is itself the finding, not a defect.
