Fix status: documented_behavior Limitations: - Derived from SDK source code on main (cloned 2026-09-27); no issue thread read for this string. Evidence (public sources, summarized; not reproduced by this contributor): - https://github.com/xai-org/xai-sdk-python/blob/main/src/xai_sdk/proto/__init__.py (official_docs, 2026-09-27, documented_behavior): Proto package imports v5 stubs if protobuf major==5, v6 stubs if major==6, else raises ValueError(f"Unsupported protobuf version: ..."). - https://github.com/xai-org/xai-sdk-python/blob/main/pyproject.toml (official_docs, 2026-09-27, documented_behavior): Dependency constraint "protobuf>=5.29.4,<7".
