    "Intervals pass all eight isolated stock comparisons. All twelve final ARRAY isolated comparisons are slower and remain accepted native coverage groundwork after the maintainer-authorized two-pass limit; no performance opt-in.",
    "ARRAY full jobs also remain slower; the artifact retains all initial, intermediate, final and actual canonical fallback measurements.",
    "Two measured passes: borrowed content hashing; then homogeneous column casts and metadata-independent borrowed equality. No additional optimization passes were performed after the second pass; v5 correctness fixes and final-library remeasurement are recorded separately.",
    "Initial 2.2 measurements used untyped CASE NULL; explicit typed ARRAY NULL was subsequently required for Flink1.18. Both forms have the same logical 2.2 values/types. The rejected 1.18 fixture produced no measurements.",
    "Validated v5 adds correctness-only STRING carrier normalization and logical key descriptor/slot-width fixes after the two measured optimization passes; all final isolated gates and complete jobs were rerun against v5. Earlier measurements remain separately recorded.",
    "No broad RAW/VARIANT/STRUCTURED/catalog work or user functions added."
