Start by reproducing the reported prompt, “Please check Convoy.cs,” with Claude Code v2.1.263 on win32 and compare the repeated API errors and request ID. The issue does not name an implementation file or test; done would require identifying a reproducible false-positive safeguard and documenting or verifying a project-side resolution.
