Countdown Latch Remediation Report

Compare arrivals at a latch against the needed count and turn the remaining count into a release, wait, or escalate remediation action.

latch remaining The needed count and arrivals are scalars, so the remaining work that drives the remediation action stays deterministic without awaiting a live latch.
