"""模块 B 创意搭建子系统 — 主循环入口(P0-A / P0-C / P0-E,2026-06-09)。

数据流(三阶段,先审后挂):
  Phase 1 — 准备:
    扫账户 → 关联点过滤(读调控当日 latest_decisions 排除 pause)
    → find_ads_needing_creatives
    → 对每条广告 prepare_one_creative_for_ad(召回 + 上传图 + xcx/save + build body)
    → pending_records (含完整 Phase 3 用的 _request_body)
    → 写 outputs/data/creation_pending_{date}.json(追溯 + 独立 apply 用)

  Phase 2 — 审批(若 CREATION_APPROVAL_REQUIRED=True):
    run_approval_workflow 生成 20 列 xlsx → 上传飞书 sheet → 发链接 → 轮询读决策列
    actions {row_idx: approve/reject/hold}
    → 写回 records["action"]

  Phase 3 — 执行:
    对 action=approve 的 → POST /dynamic_creatives/add
    → 写 outputs/data/creation_run_{date}.json
    → 发飞书"执行汇报"消息

开关 CREATION_APPROVAL_REQUIRED=False 时跳过 Phase 2,全 records 直接 approve。
