1//! Compatibility shim — the admission controller has moved to
2//! [`oxirs_core::sla::admission_controller`].
3//!
4//! The `From<AdmissionError> for MultiTenancyError` conversion stays here
5//! (rather than in `oxirs-core`) because [`MultiTenancyError`] is local to
6//! `oxirs-vec` and Rust's orphan rule forbids implementing a foreign trait for
7//! a foreign error.
