+benchmark_v3.py — Production robustness benchmark suite.
+
+Tests:
+  - Coding tasks (correctness)
+  - Tool safety (sandbox enforcement)
+  - Memory improvement (cold vs warm)
+  - Multi-agent consistency
+  - Immune system robustness
+  - Context budget compliance
+  - Failure graceful degradation
+
+Run:
+    python -m purpose_agent.benchmark_v3 --suite all --model mock
+    python -m purpose_agent.benchmark_v3 --suite local --model ollama:qwen3:1.7b
