//! # Functional-status emit bridge — `nornir-claude` → test matrix
//!
//! The single internal call site this crate uses to push a *functional* row into
//! the [`nornir_testmatrix`] matrix, so `nornir test --features testmatrix`
//! records whether `nornir-claude`'s real surfaces — the deterministic
//! [`OfflineTransport`] send loop and the [`resolve_credential_from`] precedence —
//! ACTUALLY behave, without eyeballing.
//!
//! ## Release strips everything
//! The `testmatrix` cargo feature gates the whole bridge: with it OFF (the
//! release default) [`emit`] is an `#[inline]` no-op and `nornir-testmatrix` is
//! not even linked. Lit ONLY under `cargo … --features testmatrix`.
//!
//! [`OfflineTransport`]: crate::OfflineTransport
//! [`resolve_credential_from`]: crate::resolve_credential_from
