+/** # 脚本说明
+ * SERP 单号日容量测试器(用户 2026-10-29 目标:测一个 Profile 一天能执行多少请求):
+ *   SERP_TOKEN=xxx bun serp-profile-capacity.ts --hours 24 --label cap \
+ *     --spec "32706610:5,85459817:60,31923651:160,20374881:320"
+ * 每个 Profile 独立调度,按指定速率(req/h,±30% 人性化抖动)发 sticky 请求:
+ *   GET /api/serp/html/search?q=...&runtime=fetch&profile=<指纹>
+ * (sticky+fetch 绕过占用锁/令牌桶/冷却,速率完全由本脚本控制,测量纯净)。
+ * 每条记录写 data/<label>.jsonl;每 30 分钟写 data/<label>-live.json 汇总与控制台摘要。
+ * 判定:200=ok;x-serp-gate:1=门壳;502 CAPTCHA_DETECTED=验证码;
+ * 验证码后该号转「探测模式」(1 次/10 分钟)直至首个 200 恢复(记录恢复分钟数),
+ * 之后恢复原速率,观察是否在相近累计量再次触发(区分「粘性惩罚」与「自然衰减」)。
+ * 指纹失效(重建新指纹,应答「Profile 不存在」)则该号终止并记录最终容量。
