Primes¶
- Race Condition
- The same shape governs emergency-room triage when two patients arrive at the same instant for the one available trauma bay: the shared state is the bay, the missing contract is an explicit triage rule, and absent one, raw arrival order (an implicit and often unfair sequencing rule) decides — the remedy is a priority discipline (acuity-based triage), the same priority-queue intervention used in scheduling, carrying the identical throughput-versus-fairness trade-off.
This sourceDefines the five-level acuity-based triage that replaces raw arrival order with a priority-queue sequencing discipline, trading throughput against fairness.

- Afterward Level 2 is reserved for its intended band and again moves a patient up the queue — because the threshold, not just the label, was moved.
This sourceDefines the intended ESI level-2 clinical band and gives those patients priority over less urgent categories.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 4 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
