Unpinned channel contradicts stated reproducibility goal
Low Severity
The PR description states this "bootstraps reproducible Rust toolchain pin," but
channel = "stable"is a rolling target that resolves to a different compiler version every six weeks. This doesn't actually pin or reproduce anything — builds run today and builds run next month may use different Rust versions, potentially introducing breakage. A reproducible pin would specify a concrete version like"1.85.0".Reviewed by Cursor Bugbot for commit f74c612. Configure here.
