Known evidence gaps
What is intentionally missing.
- No hands-on Muse Code repository test has been run by this site.
- No independent Muse Spark 1.2 aggregate score is quoted without a stable versioned source.
- No product availability is inferred beyond Meta’s current macOS and Linux statement.
- No community comment is treated as representative user research.
