-                GUI adapter mutation thresholds are intentionally low: the JavaFX
-                Application lifecycle requires a display or headless Monocle runtime
-                which is introduced in a later work package. Once Monocle smoke tests
-                are in place, these thresholds will be raised.
+                GUI adapter: PIT is skipped entirely. The JavaFX Application lifecycle
+                cannot be meaningfully mutation-tested without a running display or
+                Monocle runtime, and the remaining testable surface is too small to
+                produce useful mutation scores. Mutation analysis is deferred until
+                GUI coverage matures.
