+## Pre-Flight Plan Review
+
+Before dispatching Task 1, scan the plan once for conflicts:
+
+- tasks that contradict each other or the plan's Global Constraints
+- anything the plan explicitly mandates that the review rubric treats as a
+  defect (a test that asserts nothing, verbatim duplication of a logic block)
+
+Present everything you find to your human partner as one batched question —
+each finding beside the plan text that mandates it, asking which governs —
+before execution begins, not one interrupt per discovery mid-plan. If the
+scan is clean, proceed without comment. The review loop remains the net for
+conflicts that only emerge from implementation.
