//! Post-response quota accounting outcomes.
//!
//! The response has already been served by the time accounting runs, so a
//! failed write cannot deny the request. Under `Closed` the request is instead
//! recorded as failed, so uncounted spend is visible in the audit trail rather
//! than only in a log line.
