### Rationale for this change The delta binary packed decoder accepts header combinations that do not satisfy the Parquet encoding rules. Some combinations narrow into smaller Go fields or reach decoding with zero-sized miniblocks, producing inconsistent results instead of a decoder error. ### What changes are included in this PR? - Validate block size, miniblock count, values per miniblock, and encoded value count before narrowing them. - Reject a used delta bit width that exceeds the target integer width. - Keep validation of bit widths at use time so padding miniblocks remain compatible. ### Are these changes tested? Yes. Focused tests cover each invalid header invariant and an oversized used bit width. -- This is an automated message from the Apache Git Service.
