allow-policy-legacy

Part of cargo-allow, a direct source-tree exception ledger for Rust repositories.

What this crate owns

allow-policy-legacy contains adapters for migration from supported older policy formats into canonical cargo-allow policy entries. It is for replacing bespoke xtask/TOML allowlists with policy/allow.toml while preserving review intent where possible.

Generated migration output should remain reviewable. Baselines should stay baseline_debt until a human reviews, narrows, evidences, or removes them.

Who should use it

Most users should use the cargo-allow migrate command. Depend on this crate directly only when building a migration integration around cargo-allow policy internals.

Claim boundary

This crate converts source-policy data. It does not scan repositories, compile code, run Cargo metadata, execute legacy xtasks, run proof tools, or decide that an exception is safe.

Stability

This crate is versioned with the cargo-allow workspace. Public APIs may evolve as migration adapters and canonical policy rendering mature during the 0.x series.
