//! Module: ops::runtime::metrics::auth::sessions

//! Responsibility: record auth metrics for session lifecycle and bootstrap outcomes.
//! Does not own: session storage, delegated-token verification, or endpoint DTOs.
//! Boundary: auth workflow calls these ops helpers after typed outcomes are known.
