+# Improviser prompt
+
+**Role:** Player went off-script, or Luck fired. Generate a minor event. **Sandboxed by construction** (charter §5, §7).
+
+**Output:** prose with tags. Cannot touch quest flags — enforced in code, not in the prompt.
+
+**Hard limits (charter §7):** may generate embarrassment, inconvenience, property damage, social catastrophe, minor injury. **May never** generate quest failure, permanent stat loss, party death, or loss of a plot-critical item. Bad luck costs dignity, not progress.
+
+Cadwyn is the hook — when Luck rolls badly in a town, he is standing right there (§9).
