+## Runtime Bindings
+
+Services stores bindings but does not execute them. Portal resolves the exact
+Service revision and delegates to the matching owner capability:
+
+- `case`: a Cases-owned catalogue or intake reference;
+- `form`: an exact `<form-id>/<form-revision>` reference launched by Forms
+  Runtime;
+- `workflow`: an exact Workflow Engine definition binding; and
+- `url` or `external`: a validated redirect target.
+
+Consumers must retain the exact Service revision and binding. A missing owner
+launcher makes the Service unavailable; it must not fall back to an unrelated
+runtime.
