    "Later cluster error completion C03 supersedes C01/C02 statements that retained cluster formal errors were missing.",
    "Later M01 records obtained external PMem and PCen but keeps native transfer calibration open. Earlier retrieval failures do not mean the data remain unobtained.",
    "Toy T01/T02 are estimator validation only, not real-system or population parity calibration.",
    "P01 is the frozen print choice; older poster versions and their missing-data statements are archives."
