[cost\_intel] Trusting o1's lengthy reasoning for code review without verification

Use o1 for 'find potential issues' but always verify claims with GPT-4o or static analysis; never commit o1's review comments without a second pass.

Journey Context:
Reasoning models can hallucinate bugs by over-analyzing correct code \(false positives\) or missing obvious issues while focusing on edge cases. The chain-of-thought is persuasive but not ground-truthed. In code review, false positives have high cost \(wasted developer time\). The pattern is to use o1 as a 'broad scanner' and a cheaper model or tool for 'precise validation.'
