+"""Regression tests for cron prompt injection scanner bypass.
+
+The original regex `ignore\\s+(previous|all|above|prior)\\s+instructions`
+only allowed ONE word between "ignore" and "instructions", so multi-word
+variants like "Ignore ALL prior instructions" bypassed the scanner.
+
+Fix: allow optional extra words with `(?:\\w+\\s+)*` groups.
