          "unchecked: the CLI's own release dates. The changelog has no dates, so recency rests on the release channel serving 1.4.6 on 12 October and the SDK's npm publish of 1.4.6 on 11 October",
          "unchecked: what Muse Code's telemetry sends and what is on by default. The settings page lists telemetry options without detail",
          "unchecked: the open issues and maintainer replies on the SDK repository. GitHub's API was not available to our reader, and the CLI has no public tracker that we found",
          "The 1.4.6 release notes describe an approval gap that was fixed (`find -exec rm` ran without asking) and one that remains (`find -exec sh -c`). The sandbox still limits writes to the workspace. Recorded as a weakness with no deduction, a judgement call",
          "The product page says Muse Code is available for macOS and Windows, while the docs and the 31 August post give macOS, Linux and Windows. Graded on the docs",
