Four artifacts from the machine audit of one Revit electrical model of our
GB300-class data center reference design. Files 01-03 are published exactly as
the pipeline wrote them; in file 04 the one local file path was shortened to a
file name. V336 is the internal identifier of the reference design. The SHA-256
values identify the exact model saves the readbacks ran against (two successive
saves of the same model).

01_READBACK_METADATA_ONLY.json
  An independent read-only readback that accepts author-written edge metadata.
  Status PASS: 96 equipment, 156 connector endpoints, 78 electrical systems,
  78 edges resolved from metadata. Note the same file already reports
  nativeAllRefsEdges = 0 - the number the pass criterion did not look at.

02_READBACK_STRICT_FAIL.json
  The same validator rerun with a strict criterion: an edge counts only if the
  native connector AllRefs graph closes it. Result: nativeAllRefsEdges = 0 and
  exact two-endpoint system membership = 0 across all 78 systems. Status FAIL.
  This is the published finding "78 circuits, zero strictly connected edges":
  placing equipment and writing edge metadata does not wire a model.

03_CONNECTOR_MAP_MACHINE_VALIDATION.txt
  The port-register coverage gate for the same design: 1,539 port instances as
  unique endpoint instances (not type codes), 196 edges each bound to exactly
  one allowed rule. PASS_MEANING states exactly what this pass does and does
  not establish - row coverage and linkage only, no geometry, no Revit
  execution.

04_REVIEWER_CLOSURE_VERDICT.json
  The closure verdict an AI reviewer issued over the Rev1 run: ten gates each
  with status and evidence, an allowedClaim stating what may be said of the
  model, and forbiddenClaims listing what may not. This allowed/forbidden
  pattern is the cheapest defence against a model (or a report) claiming more
  than its evidence.
