Current evaluation

Snapcraft fails with 'cargo not found' when building a Rust project with base: core22. Issue is unlabelled and has had no maintainer response in 1114 days.

Suggested action: needs triage

Reason: The issue has no labels, no maintainer comments, and no assignee after 1114 days. The error message is clear ('cargo not found and part does not depend on rust-deps'), but it's unclear whether this is a user configuration error, a missing feature in snapcraft's core22 support, or a legitimate bug. Without maintainer assessment, the appropriate action is triage to determine if this is still reproducible in current snapcraft versions and whether it requires a fix or documentation.

Impact: 60 Quick Win: 36.0 Staleness: 85 Complexity: 40 Confidence: 65 Support Request: 50
