Python: [Issue]: MCP workflow resume test failed in Python 3.12 Windows CI #10293

Category

Build or CI

Problem

The Python Tests (3.12, windows-latest) job failed on #10177, a PR that only updates the A2A quickstart README. The failure triggered cancellation of four other jobs in the Python test matrix, and Merge Gatekeeper failed.

Evidence

• Windows / Python 3.12 job log
• Failing test: TestApprovalFlow.test_auth_context_binding_survives_workflow_resume[True-True]
• Assertion location: python/packages/declarative/tests/test_invoke_mcp_tool_executor.py:471
• Expected handler.call_count == 0 after resuming from a checkpoint with a changed authorization context. Actual: handler.call_count == 1.

I observed this in one CI run. Reproducibility is unknown.

Desired Outcome

Determine whether the failure reproduces on the base commit under Windows / Python 3.12, and make the test reliable so it does not block unrelated PRs.

Language

Python
