Lineage Independence Audit¶
Audit procedure — instantiates Independent Convergence Recognition and Transfer Design
Enumerates the recurring cases and reconstructs each one's full provenance — origins, contacts, sources, and influences — to build the map that establishes whether the cases really arose separately.
Before any recurrence can be called convergence, you need to know who these cases even are and where each one came from. The Lineage Independence Audit does that groundwork. It registers the set of cases that share the form and then reconstructs, for each one, an open-ended provenance history — its origins, its influences, the people and sources it drew on, its contacts with the other cases — assembling them into a map of how the cases relate. Its defining property is that it is a map-building reconstruction, not a fixed screen: it doesn't run a checklist of known copy-channels, it does the archival, interview, and record work to draw the actual genealogy of the cases, so that later independence judgments have a real substrate to rest on. It answers "how are these cases connected, if at all?" by building the picture rather than testing pre-named paths through it.
Example¶
Two research labs, one in Europe and one in Asia, post near-identical graph-embedding methods within a few months of each other, and a program committee wants to know whether this is genuine parallel discovery or one lab quietly building on the other. The audit first registers the cases crisply — which two papers, which exact method, what counts as "the same" here. Then it reconstructs each lab's provenance: advisors and their academic lineages, shared co-authors, whether either cited the other's earlier preprints, overlapping conference attendance, shared benchmark datasets, funding from a common program, and any personnel who passed between the groups. The output is a relatedness map: the two groups share no advisors and no co-authors, attended different venues, but both built on the same public benchmark and one widely-read prior preprint neither authored. That map doesn't yet declare independence — it makes the connections and non-connections explicit, so the diffusion screen and the confidence grade have something concrete to work from. It is the modern instance of a very old phenomenon: the same discovery surfacing in more than one place at nearly the same time.[n1]
How it works¶
- Register the cases first. Fix the case set and the exact shared form before tracing anything, so the audit maps a defined population rather than a shifting anecdote.
- Reconstruct provenance per case. For each case, assemble its origin story — sources, mentors, prior art it drew on, and its documented contacts with the other cases — from records, not assumptions.
- Draw relatedness, not a verdict. Render the cases and their connections as a map (shared and non-shared origins), leaving the independence judgment to the screens that consume the map.
- Log gaps as gaps. Where provenance can't be reconstructed, mark it unknown rather than absent; an un-traceable history is a hole in the map, not evidence of independence.
Tuning parameters¶
- Registry inclusion bar — how similar a case must be to enter the set. A tight bar keeps the population clean but may drop informative near-cases; a loose bar is inclusive but muddies the map.
- Provenance depth — how many generations of influence back the history is traced. Deeper tracing catches distant common sources but costs archival effort and hits diminishing returns.
- Evidence standard — documentary proof versus plausible reconstruction. Demanding documents is rigorous but slow; accepting reconstruction is fast but softer.
- Gap treatment — whether unknown provenance is flagged prominently or quietly. Prominent flagging keeps downstream users honest about how complete the map really is.
When it helps, and when it misleads¶
Its strength is that it produces the shared substrate every other independence judgment needs: a concrete, case-by-case picture of how the cases are and aren't connected, built rather than assumed. Nothing downstream — the diffusion screen, the confidence grade — is trustworthy without it.
Its failure mode is mistaking an incomplete map for a clean one: absence of found connection is not presence of independence, and a shallow audit can look reassuringly sparse simply because it didn't dig. A classic misuse is registering the cases so narrowly that only the flattering, clearly-independent ones remain. The guarding discipline is to make provenance gaps loud — an unknown origin is a marked hole, never a tacit vote for independence — and to freeze the registry's inclusion rule before the results could tempt anyone to curate it.
How it implements the components¶
lineage_independence_map— the audit's central product: the reconstructed genealogy of the cases showing their shared and separate origins, influences, and contacts.independent_case_registry— it fixes and maintains the defined set of cases under comparison, with the inclusion rule that says what belongs in the population.
This audit builds the provenance map but does not run the fixed copy-channel screen or trace specific adoption paths: hidden_transmission_check and adoption_trace belong to Hidden Diffusion Checklist, its nearest independence-checking twin, which tests named channels against the map this audit produces. It also does not classify the shared trait's descent (candidate_convergent_form) — that is Homoplasy vs. Inheritance Review.

Editorial Notes¶
Form Classification¶
Form family: Assessment, Review & Assurance
Rationale: The audit evaluates reconstructed origins, contacts, sources, and influences and produces an independence or shared-lineage finding.
Nearest alternative: Analysis, Modeling & Optimization — A provenance map is modeled, but its defining output is assurance about whether cases arose separately.
Review outcome: Adjudicated after independent review; high confidence.
Origin Attribution¶
Primary origin: Sociology & Anthropology
Origin pattern: Historically ambiguous
Present-day reach: Multi-domain
Rationale: The audit's intellectual anchor is sociology of knowledge, especially Merton's study of multiple independent discovery and diffusion.
Related originating lineages:
- Ethnography & Qualitative Methods — Interviews and qualitative field evidence materially shape reconstruction when written transmission records are incomplete.
- History & Historiography — Historical source criticism and influence tracing independently supply the evidence methods used to establish lineage.
Review resolution: Both independent reviews assign primary provenance to sociology_anthropology. The queued secondary differences (reported_ambiguity, alternate_origin_disagreement, origin_mode_disagreement) are reconciled by retaining ethnography_qualitative_methods, history_historiography only as formative or independently established lineage(s), not merely as application domains. origin_mode=historically_ambiguous records the provenance relationship, while domain_reach=multi_domain separately records applicability breadth. confidence=medium preserves the more cautious assessment, and encyclopedia_synthesis=true records whether either reviewer identified a corpus-specific synthesis.
Attribution caveat: The generalized audit sits across sociology of knowledge and historical provenance research.
Encyclopedia synthesis: The exact catalogued form synthesizes established practice rather than reproducing a single standard historical label.
Review outcome: Reconciled after independent review; medium confidence.
Notes¶
[n1] Sociologist Robert K. Merton documented the pervasiveness of multiple independent discovery — the same finding arrived at by more than one person at nearly the same time (calculus, natural selection, and many others) — arguing that "multiples" are the rule rather than the exception. The audit exists precisely because such multiples must be distinguished from quiet borrowing. ↩
