…version ParquetReaderFactory drops conjuncts whose top-level columns are not in the read type, but a nested field predicate (s.b) passed that check as long as s was projected. When the read type prunes s to ROW<a>, Parquet reads the unrequested s.b column as all-null and skips row groups that contain matching rows. Also require the whole nested path to survive the read type; an OR touching a pruned path is dropped as a whole. Generated-by: Claude Code

Purpose
fix #10378
withReadTypeprunes a nested field that a filter references (s.b = 7withs ROW<a>), withoutexecuteFilter().s.bpasses and Parquet reads it as all-null.ParquetReaderFactorynow also requires the whole nested path in the read type. AND keeps projected conjuncts; an OR touching a pruned path is dropped.ReadBuilderpath is affected. Flink/Spark SQL keep filter fields in the read type;executeFilter()is already safe.Tests
AppendOnlySimpleTableTest#testParquetFilterOnUnprojectedNestedField; fails on master.ParquetReadWriteTest#testReadWithUnprojectedNestedFilter(AND, OR); both fail on master.ParquetReadWriteTest54/54 andAppendOnlySimpleTableTest114/114 pass; checkstyle and spotless pass onpaimon-formatandpaimon-core.
