  "message": "[fix](nereids) strip NULL access path when OFFSET path exists for the same field in NestedColumnPruning\n\nstripNullSuffixPaths() already contains the logic to remove [col.NULL] when\n[col.OFFSET] covers the same prefix (lines 834-839), but it was only called\nin the string-like and general branches, not in the array/map early-continue\nbranch. This caused queries like `SELECT cardinality(arr), arr IS NULL` to\nemit redundant [arr.NULL] alongside [arr.OFFSET] in the access paths.\n\nFix: move stripNullSuffixPaths() call to line 278 (before all type-specific\nearly-continue branches) so it applies uniformly to all complex data types.\n\nAdd regression tests covering array root, map root, struct string subfield,\nstruct array subfield, and struct map subfield.\n",
