# Which issue does this PR close? - Closes #10615. # Rationale for this change `ShreddedSchemaBuilder` can already parse indexed Variant paths, and core Variant shredding supports lists, but schema construction currently panics when a path reaches an index. This prevents callers from describing list element schemas through the builder. # What changes are included in this PR? - Add a list node to the builder's intermediate schema tree. - Treat numeric indexes as references to the shared list element schema, including for nested lists. - Document the index behavior and add coverage for list-of-struct and nested-list schemas. - Build the existing list shredding test schema through `ShreddedSchemaBuilder`. # Are these changes tested? Yes. `cargo test -p parquet-variant-compute test_variant_schema_builder` passes (11 tests). # Are there any user-facing changes? Yes. Callers can now use indexed paths such as `items[0].id` when constructing shredding schemas. This is backward compatible. -- This is an automated message from the Apache Git Service.
