Joint calibration-coordinate diagnosis

48/48 audits pass; state: complete. The study used 4032 LP proposals and at most 8064 exact certificates.

Every saved training system retains all 27 physical and 15 shared-error coordinates. LP proposals alone do not certify a bound; the exact dual-plus-box certificate supplies the mathematical check. No native integration, original aircraft reads or observed fits occur.

21/27 physical coordinate ranges and 12/15 auxiliary ranges show no material improvement in any passing case (material means at least one part per million). Joint correlations remain; these are not measurements of device calibration.
