[cost\_intel] Security vulnerability detection in authentication/crypto code paths

Use o1/o3 for final security pass despite 20x cost; instruct models miss 40% of subtle race conditions and injection vectors that o1 catches

Journey Context:
On OWASP Benchmark and internal security evals, GPT-4o achieves 60% true positive rate on vulnerability detection while o1 achieves 95%. The cost of a false negative \(production breach\) dwarfs the $2 vs $0.10 API cost difference. Chain-of-thought prompting with 4o raises detection to only 70% and introduces false positives. Reasoning models are essential when the task requires exploring deep execution paths \(e.g., 'can this user input reach the eval function through this middleware chain?'\).
