Atomic Guard Remediation Report

Turn the number of waiters behind a held guard into an enter, backoff, or page remediation action.

guard contention The waiter count behind a held guard is kept as a scalar, so the remediation action stays deterministic and never depends on atomic identity or scheduler timing.
