WaitGroup Barrier Remediation Report

Compare arrivals at a barrier against the expected count and turn the pending count into a release, wait, or escalate remediation action.

barrier pending The expected count and arrivals are scalars, so the pending work that drives the remediation action stays deterministic without waiting on a live barrier.
