This is enforced by the security software in the session, not by filesystem/network sandboxing.\r\n- The fixture's `3840x2160` vs. the real `1536x864` screen is a separate mismatch but not the blocker — capture fails identically at the correct `1536x864` resolution.\r\n\r\n**Next Steps**\r\n- Screen recording requires disabling/quiescing FinSAFE screen-capture protection, or launching the capture from the real `Default` interactive desktop. This is an environment-level change I can't perform here.\r\n- Per-run diagnostics are written to `screen-recording-result.json` in the workspace root, and failed outputs are under `screen-recordings/`.
