  "relevance": "For Exact mixed-dimension subspace-code number A_2(7,4), record mdsc-attempt-source-live-audit (“Audit the primary sources, current bounds table, and production record”) documents a concrete method, search boundary, or failed route. The record states: The audit confirms the published 334–388 interval.",

  "body": "The audit read both primary papers, checked their versioned PDFs and source licenses, inspected the current online bounds entry, and ran dated arXiv searches for later improvements. A read-only production orientation resolved the permanent target exactly and returned an empty research-memory projection. Production check-plan calls for the bounded replacement searches through radii five and six returned proceed-with-caution because no close prior record was retrieved. The checked-out local index did not yet contain this recently published target, which is an environment lag rather than a target-integrity problem.",
