Groq's `openai/gpt-oss-20b` can return reasoning content instead of honoring forced tool choice in live integration tests. The forced tool-choice coverage now uses Groq's recommended `qwen/qwen3.6-27b` replacement with reasoning disabled, while leaving gpt-oss coverage in place for reasoning-specific tests. ## Changes - Add a dedicated tool-calling model constant for forced tool-choice integration coverage. - Update sync and async tool-choice tests to use `qwen/qwen3.6-27b` with `reasoning_effort="none"`. - Remove stale xfail markers from streaming tool-call tests and assert the normalized aggregated stream output, including preserved tool-call IDs.

Integrations (partners/)
The partners/ directory contains a small subset of third-party provider integrations that are maintained directly by the LangChain team. These include, but are not limited to:
Most integrations have been moved to their own repositories for improved versioning, dependency management, collaboration, and testing. This includes packages from popular providers such as Google and AWS. Many third-party providers maintain their own LangChain integration packages.
