+
+Fix policy form validation for Description and Priority fields.
+
+- Add a 255-character max-length Yup rule to the Description field, with inline error
+  feedback matching the Display Name pattern (validation error on blur rather than
+  hard-blocking input at the DOM level).
+- Add `.integer()` and `.required()` Yup rules to the Priority field so decimal values
+  (e.g. 500.5) and an empty field are rejected with an explicit error message instead of
+  silently coercing to an integer or defaulting to 500.
+- Add `step={1}` to the Priority number input and block `.`/`e`/`E` characters via
+  `onKeyDown` and `onChange` guards to prevent decimal strings from bypassing the Yup
+  integer check through JavaScript's `Number()` coercion.
+- Update the Priority label to "Priority \*" to indicate it is a required field.
