- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (129 of 133), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (129 of 133), so this covers what we could see, not the whole tree. View diagnostics → Partial
