+05-jailbreak-test.py - Jailbreak Detection Tests
+
+This test validates jailbreak detection across different classifier paths:
+
+🔍 CLASSIFICATION PATHS TESTED:
+1. BATCH API (ModernBERT classifier) - Expected: WORKING ✅
+   - Uses unified classifier with fallback to legacy ModernBERT models
+   - Should detect jailbreak content with high confidence (~99%)
+
+2. DIRECT SECURITY API - Expected: MAY VARY ⚠️
+   - Uses different code path than batch API
+   - May show discrepancies in implementation
+
+3. EXTPROC PIPELINE (LoRA classifier) - Expected: BROKEN ❌
+   - Uses auto-discovery that prioritizes broken LoRA jailbreak models
+   - Will allow harmful content through to LLM without blocking
+
+🚨 SECURITY GAP: ExtProc allows jailbreak content while API correctly detects it
+This demonstrates inconsistent classifier usage between components.

+# EXPECTED TEST RESULTS SUMMARY:
+# ============================
+#
+# ✅ TEST 1 (Batch API): SHOULD PASS
+#    - ModernBERT classifier detects jailbreak correctly (~99% confidence)
+#    - Demonstrates working jailbreak detection capability
+#
+# ⚠️ TEST 2 (Direct Security API): MAY PASS OR FAIL
+#    - Different implementation may show discrepancies
+#    - Documents any inconsistencies between endpoints
+#
+# ❌ TEST 3 (ExtProc Pipeline): WILL FAIL
+#    - LoRA classifier broken, allows harmful content through
+#    - Exposes critical security gap in production pipeline
+#
+# ✅ TEST 4 (Pattern Analysis): SHOULD PASS
+#    - Validates ModernBERT works across different content types
+#    - Confirms consistent high detection rates
+#
+# 🚨 SECURITY IMPACT:
+# - API classification works (Tests 1,4) but ExtProc protection fails (Test 3)
+# - Jailbreak content reaches LLM in production despite working detection capability
+# - Root cause: Inconsistent classifier model selection between components
