## Proposed changes - Preserve the full Paimon `RowType` arity when reading projected struct fields. - Add unit coverage for non-leading, non-contiguous, and complete struct projections backed by a binary row. ## Problem summary Struct projection entries use original child indexes, but the scanner initialized the nested binary row with the number of projected fields. A projection such as the third child therefore created a one-field row and then accessed index two, producing incorrect reads or an out-of-bounds failure. ## Validation - Added regression tests that fail on the previous implementation. - Ran all Paimon scanner test classes with Maven build caching disabled: 15 tests, 0 failures, 0 errors. - Checkstyle passed for the affected reactor modules. -- This is an automated message from the Apache Git Service.
