让 Codex 根据自己的 Session 记录分析自身的 TTFT 和 TPS

怀疑 Codex 订阅不同时段的响应速度不一致，使用以下命令让 Codex 自己分析自己的记录

Analyze all Codex rollout logs in ~/.codex/sessions and ~/.codex/archived_sessions. Generate two 24-hour boxplots grouped by request-start hour in China Standard Time (UTC+8): (1) best-effort TTFT in milliseconds and (2) effective output tokens per second. Use exact TTFT where available and inferred timestamps otherwise. Use logarithmic Y-axes
