Rust lints

A lint rejects a whole class of defect for every author. A written rule ("no unsafe", "no bare allow") is not enforcement until a lint level or a CI check carries it. Write down only the level that is actually deployed: a document that shows a target level as the current one makes reviewers stop checking what the compiler does not check either. Read references/triage.md when a clippy, cargo fmt, or cargo doc gate is red.

Where lint policy lives

Put every lint level in the workspace root Cargo.toml. Every member inherits it:

[lints]
workspace = true
