The Test (Node 20.x / windows-latest) job failed in codex-transcript.test.ts due to invalid JSON in a test fixture on Windows paths. The spaced session_meta fixture embedded raw cwd text, which broke JSON parsing when cwd contained backslashes.

• Failure scope

  • codex adapter transcript scoping > matches cwd even when the session_meta line uses spaced JSON formatting
  • Windows-only repro from unescaped cwd in manually formatted JSON

• Change

  • Updated the spaced JSON fixture builder to serialize cwd with JSON.stringify(cwd) instead of direct interpolation.
  • This preserves the spaced formatting intent while making the fixture valid across platforms.

• Resulting behavior

  • The test now exercises the intended parser/matcher behavior rather than path-escaping artifacts from the host OS.

const line1 = spaced
  ? `{"type": "session_meta", "payload": {"cwd": ${JSON.stringify(cwd)}}}`
  : JSON.stringify({ type: 'session_meta', payload: { cwd } });
