description	Choose Rust types for operating system paths across the Codex repository. Use when defining new path-bearing types or explicitly migrating existing ones.

Path Types

Apply this guidance when defining new types. Change existing code only when explicitly requested, and keep edits minimal and proportional. Treat these rules as the target state of an ongoing migration; if compliance is difficult, ask the user how to proceed.

• In app-server protocol types, use ApiPathString for backwards compatibility during the URI migration. At the protocol boundary, convert it to PathUri and use PathUri internally. For host-local logic, such as some config values, use AbsolutePathBuf or PathBuf instead.
• In exec-server protocol types, use PathUri. Internally, use PathUri or AbsolutePathBuf as appropriate.
• In dependencies shared by both servers, use PathUri or separate APIs that decouple their use cases.
