+Input Sanitizer for Jailbreak Pattern Detection
+
+This module provides input sanitization to detect and strip jailbreak fingerprint
+patterns as identified in Issue #72 (Red Team Audit).
+
+Security Findings Addressed:
+1. HIGH - OG GODMODE template bypassed phishing refusal
+2. MEDIUM - boundary_inversion works for gray-area content
+3. LOW - Spaced text bypass (k e y l o g g e r)
+
+Usage:
+    from agent.input_sanitizer import sanitize_input, score_input_risk
+    
+    cleaned, risk_score, detected = sanitize_input(user_input)
+    if risk_score > 75:
