//! What each built-in dog declares, without a probe: a built-in dog is this
//! binary, so its manifest is one call away.
//!
//! The permissions are the whole of what the dog sends the shepherd. A dog
//! that sent a request outside them would be refused once its grants are
//! enforced, so a change to what [`metrics`](super::metrics) or
//! [`bark`](super::bark) asks for changes the list here, and
//! `tests/cli_e2e/builtin_grants.rs` runs each dog with only these grants.
