Fix status: documented_behavior Other error fragments: - enable_auto_chunking=True requires input_type='document' - auto-chunking expects one string per document - chunk_size and chunk_overlap require enable_auto_chunking=True Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/voyage-ai/voyageai-python/9aca465efd0011c478031f6d584b70a3a4393a7c/voyageai/chunking.py (official_docs, unknown, documented_behavior): validate_and_normalize_contextualized_inputs enforces these input shape / input_type / auto-chunking rules.
