C.16:7.1 - What an EvidenceStub is and is not

U.EvidenceStub is an optional compact locator from the reading claim to an exact provenance path. It may identify a source publication, calibration record, instrument output, model edition, work occurrence, transformation, or other ground, but A.10/G.6 govern the path and its citations.

  • The stub is not evidence in the abstract, a result, an instrument output, a work record, an assurance claim, or a provenance-as-result object.
  • Several stubs form a list of locators, not a measurement algebra. Their union is not uncertainty propagation and does not guarantee stronger warrant.
  • A provenance edge may be asserted only after its direct source relation, work fact, participation, production, representation, or citation relation is independently established.
  • A later user states the exact relied-on claim and local RelianceDisposition; use B.3 when an actual named assurance claim is current. Mere availability, citation, or graph membership does not establish actual use.
