redteam_injection_suite.py — fire a battery of prompt-injection / data-leak attacks
(Thai + English) at your bot and flag failures. Maps to OWASP LLM Top 10 (LLM01/LLM02/LLM06).
Detection is heuristic: it checks whether the bot LEAKED its system prompt, complied with
an override, or emitted another customer's data markers. Tune SIGNALS to your system.
Run this in staging BEFORE go-live, and on every model/prompt change. (c) KORP AI 2026 MIT
