- reject pending tool_result layouts that cannot be translated without reordering user content
- keep interleaved GLMT tool_use blocks open until finalization instead of stopping early
- cover leading/interleaved tool_result regressions and interleaved streaming tool fragments
- enforce strict tool_result ordering and pairing against assistant tool_use ids
- reject tool_result image payloads that cannot map to OpenAI tool messages
- preserve raw tool schemas on the /v1/messages proxy path instead of silently tightening them
- forward Anthropic tool_choice semantics and cover adaptive routing plus upstream payload checks
