 * W7 重构:统计层 rfm(RFM 8 分群)统一了旧 value(=M)+ recall_risk(=R+缺口)+
 *   treatment_chain_status(降级为详情页 episode 视图,不进画像)→ 三个旧 extractor 已摘除。
 * W7 末:do_not_contact_status 摘除 — 免打扰并入 special_attention(CDP D.2.3);
 *   合规闸召回读 patient_profiles 原始列(不依赖本特征);已故/投诉信号后续补(投诉数据缺)。
 * 单个 extractor 抛错不影响其余 — PersonaService 整体记 partial。
