This repo is the source of truth for bootstrapping or ratcheting Rust lint posture.

Choose exactly one surface:

- Fresh bootstrap: read [docs/bootstrap-fresh.md](/home/main/programming/projects/rust_starter/docs/bootstrap-fresh.md) and adapt the files under [template/fresh](/home/main/programming/projects/rust_starter/template/fresh).
- Retrofit: read [docs/bootstrap-retrofit.md](/home/main/programming/projects/rust_starter/docs/bootstrap-retrofit.md), then diff the target repo against [template/fresh](/home/main/programming/projects/rust_starter/template/fresh) and [docs/rust-linting-proposal.md](/home/main/programming/projects/rust_starter/docs/rust-linting-proposal.md).

House rules:

- Keep lint semantics in root `Cargo.toml`; keep runners, CI, and editor config orchestration-only.
- Make every member crate opt into `[lints] workspace = true`.
- Pin an exact stable toolchain in `rust-toolchain.toml`.
- Prefer `#[expect(..., reason = "...")]` for temporary local suppressions.
- Retrofit is ratchet work: preserve stricter local policy and justified local carve-outs; do not blindly paste the template.

Use [docs/rust-linting-proposal.md](/home/main/programming/projects/rust_starter/docs/rust-linting-proposal.md) for rationale and policy details, not as a paste target.
