## Problem Paimon can write an unannotated shredded Variant array whose element wrapper contains only a required `BYTE_ARRAY value` fallback leaf. Doris already recognizes Paimon's optional wrapper groups, but rejected this required fallback leaf during Parquet schema validation. ## Changes - Allow a required fallback leaf only for a Paimon unannotated, fallback-only array element. - Keep annotated Variant layouts, object wrappers, and array elements with a typed carrier under the existing strict validation rules. - Verify that the non-nullable fallback leaf is materialized into Variant array elements. ## Validation - ASAN BE unit tests: `ParquetSchemaTest.*`, `VariantColumnReaderTest.*`, and `PaimonVariantReaderTest.*` (82 tests passed). - clang-format 16 validation on all affected C/C++ files. - `git diff --check`.
