+id: algo.incident_triage.evaluate_dmn
+version: 1.0.0
+name: DMN decision evaluator
+intent: |
+  Wraps a DMN 1.3 decision-table evaluation as a callable UAPF-IP
+  capability. The triage BPMN invokes the three DMN tables in this
+  package (priority, ownership, routing) natively via businessRuleTask;
+  this card describes the dmn.evaluate@1 capability for cases where the
+  same evaluation is needed outside the BPMN runtime (operator manual
+  re-evaluation, batch backfill, regression testing).
+  
+  Engine-internal DMN evaluation and this capability call return the
+  same output for the same input — that property is the only thing
+  this card asserts.

+  Throws if the requested package_id is not loaded by the runtime, or
+  if the named decision_id is not present in that package's dmn/
+  directory. Triage callers fall back to safe defaults (P4, lvrtc,
+  helpdesk-l1) so the case still completes.
