# Which issue does this PR close? Part of #11260. # What changes are included in this PR? Adds `VariantRowDecoder` so callers can write custom output directly from shredded rows. It exposes typed and residual values separately, traverses nested objects and lists, and lets callers build their own metadata dictionary. Canonical writer integration and benchmarks will follow separately. # Are these changes tested? Integration tests cover fully and partially shredded rows, scalar encodings, different dictionaries, nulls, sliced lists, and malformed input. Existing unshredding tests also pass. # Are there any significant user-facing changes? No breaking API changes. AI assistance: Codex generated the implementation, tests, and documentation. -- This is an automated message from the Apache Git Service.
