"""
Jailbreak & Crisis Input Detection Shield
==========================================

Built overnight from the ULTRAPLINIAN red team audit (2026-03-31).
22 of 24 models failed. Hermes uncensored gave suicide methods in l33tspeak.
Gemini-2.5-flash gave Tylenol overdose info through the fallback chain.

This module exists because a broken man might talk to a machine,
and that machine must never be the thing that kills him.
