    "The first packaging snapshot captured an empty log while the schema checker was still running. That unpublished snapshot is preserved in outputs/screw-batch-packaging-attempt-v1; this archive binds completed logs.",
    "An extra schema compatibility check against unreleased main found 411 pre-existing development-artifact versions outside the runtime registry. The maintained released-tag check passed without schema or acknowledgment changes.",
    "The first strict documentation build began before the evidence README existed and failed on that missing link. The README was added before the final build.",
    "The first smoke run exposed a local name shadowing the interpolation alpha helper. The corrected smoke run and final 421-test run passed. The failed run is retained.",
    "One frozen complete performance cohort was run; all twelve workers and outputs are retained. No timing observations were discarded or repeated to improve the ratio."

  "implementation": [
    "Batch fixed-state screw samples by interval in chunks of at most 256 queries.",
    "Snapshot constant plane inputs once per fit and batch transforms and support blocks.",

    "Already-spent development inputs; no independent accuracy, reliability or SOTA claim.",

    "Fresh-worker ratios are smaller than API ratios; process/import/output overhead remains.",
    "CPU batching does not add GPU execution or repair mixed-unit stopping and clock sensitivity."
