[claude]

LGTM. This is a lockfile-only bump of dev-group dependencies, and the resolution is consistent.

What was reviewed:

• The bumped LangChain/LangGraph packages (langchain 1.4.3, langgraph 1.2.13, langchain-core 1.6.6) still fall within the dev-group ranges in pyproject.toml (langchain>=1,<2, langgraph>=1,<2).
• The two new transitive packages, langchain-protocol and websockets, are required by the new langgraph-sdk and langchain-core releases. Every new artifact comes from files.pythonhosted.org with a sha256 hash.
• The newest new artifact is langgraph 1.2.13, uploaded 2026-10-05, which is still inside the 7-day exclude-newer window. The [options] header moving to the relative-span placeholder format looks like a newer uv lock format, not a policy change.

Extended reasoning...

Only uv.lock changes. It moves langgraph-sdk and the related LangChain/LangGraph packages to newer versions and adds langchain-protocol and websockets as transitive dependencies. These packages come from the dev dependency group, so the change affects the test and dev environment, not the published package's runtime requirements. It touches no security-sensitive surface, the changed path isn't covered by an active CODEOWNERS rule, and there are no prior reviews or objections. Approved because this is a mechanical dependency bump within the declared version ranges, and the existing langchain integration tests in CI will exercise the newer langchain-core.
