@@ -5,6 +5,13 @@ three refusable configurations are refused. The second asserts that everything
 on validate.py's "deliberately not refused" list still STARTS - because the way

+⚠️ MUTATING THE MODULE THIS FILE GRADES? PURGE `__pycache__` FIRST - or run
+`tools/mutation_run.sh`, which does. `python3 -B` alone does NOT save you: it
+stops bytecode being WRITTEN, not a stale one being READ, and a size-preserving
+edit reverted inside one second is invisible to CPython's staleness test. That

+Read MUTATION.md before you report a survivor.
