//! This binary's [`basis_tasks::PromptHost`]: a terminal, or nothing.
//!
//! `basis-tasks` has no terminal to ask at (ADR-0011) — the same reason
//! [`TerminalApprover`] lives here and not
//! in `basis`. This is the seam that lends it one: whichever process holds a
//! task's attach lock answers `Approve::Prompt` through its own stdin, exactly
//! as the pre-extraction daemon-less CLI did.
