Redis 集合维护\n\n当前 `zAdd` **无 TTL、无上限**，长期会膨胀。建议实现时顺带：\n\n- 写入时 `ZREMRANGEBYSCORE` 清理超过 N 天（如 7 天）的旧 member\n- 或按 source 限制 ZSet 最大长度\n\n---\n\n## 推荐改动位置（实现阶段）\n\n不在 `UserController::register` 做（你已选 register_only + insertADTag 内聚），建议：\n\n**主改文件**：[`slot_user/app/service/register/AbstractRegisterService.php`](slot_user/app/service/register/AbstractRegisterService.php)\n\n- 新增私有方法，例如 `resolveLatestDotPayloadBySource(string $source): ?array`\n  - `Redis::zPopMax(RedisKeyManagerService::getDotSetKey($source), 1)`\n  - `unserialize` + 校验必需字段（至少 `fbp` 非空；`fbc` 非空才能解析 fbclid）\n- 改造 `insertADTag`：\n  - 若 `$this->fbclid` 为空，调用上述方法补全 `fbclid/fbp/ua/ip`\n  - 若补全后仍无 fbclid，`return`（不写空 tag）\n  - 否则按现有逻辑 `setInfo`\n\n**可选**：若希望仅 IMEI 走回退、不影响 Name 注册，可把回退逻辑放在 [`ImeiRegisterService`](slot_user/app/service/register/ImeiRegisterService.php) 覆写 `insertADTag`，而非改 Abstract 基类。\n\n---\n\n## 前置条件（产品/客户端）\n\n方案生效依赖用户路径：\n\n1. 用户从 FB 广告进入落地页（UA 含 `FB_IAB`）\n2. 落地页成功调用 `SiteController::fb`（带正确 `source`）\n3. 用户在合理时间窗口内完成 iOS 首次 IMEI 注册，且 `source` 与落地页一致\n\n若用户跳过落地页直接装包注册，仍无法归因——这是架构固有限制，不是实现 bug。\n\n---\n\n## 风险清单\n\n| 风险 | 级别 | 说明 |\n|------|------|------|\n| fbc 为空 | 中 | 落地页允许空 fbc，补写无效，FbDot 仍会报 fbclid 为空 |\n| 同 source 串号 | 中 | 多用户并发时可能拿错上一条 fbc |\n| pop 后写失败 | 低 | 数据丢失，仅影响单次 attribution |\n| ad_fbp 未被 FbDot 直接使用 | 低 | 当前 FbDot 用 fbclid 重新 generate fbp；落地页 fbp 写入 user tag 但 CAPI 仍用生成值。MVP 可接受；若要最佳 attribution 需后续改 FbDot 优先用 `ad_fbp`/真实 `fbc` |\n\n---\n\n## 验证建议\n\n1. 落地页 mock：POST `SiteController::fb`，确认 Redis `user:dot:set:{source}` 有 member\n2. IMEI 新用户注册（不带 fb 参数），查 `UserInfoCache` / user tag 中 `ad_fbc`、`ad_fbp`、`ad_ua`\n3. 触发 `slot_console` 注册打点，确认 `FbDot::registerEvent` 不再报 fbclid 为空\n4. 并发两条落地页 + 两次注册，观察是否出现串号（评估是否需加时间窗）\n\n---\n\n## 总结\n\n**可行，且是 iOS 上架场景下合理的补偿方案。** 实现重点不是「能不能取 Redis」，而是：\n\n1. 正确从 `fbc` 解析 fbclid 再写入 `ad_fbc`\n2. 仅在客户端无 fb 参数时回退\n3. 用 `zPopMax` 消费最新一条\n4. 接受同渠道并发下的 attribution 碰撞，或后续迭代匹配策略\n\n按你确认的范围，**只改 IMEI 新注册 `insertADTag` 即可**，无需动登录链路。\n","todos":[{"id":"parse-fbc-fbclid","content":"在 insertADTag 回退路径实现 fbc→fbclid 解析与字段映射（ad_fbp/ad_ua/ad_ip）"},{"id":"redis-pop-latest","content":"实现 resolveLatestDotPayloadBySource：zPopMax user:dot:set:{source} + unserialize 校验"},{"id":"imei-only-guard","content":"回退逻辑仅 IMEI 新注册触发（覆写 ImeiRegisterService::insertADTag 或在 Abstract 中加平台/类型判断）"},{"id":"redis-cleanup","content":"可选：SiteController 或 pop 侧增加 ZSet 过期/长度清理"},{"id":"verify-fbdot","content":"联调：落地页上报 → IMEI 注册 → 检查 user tag 与 FbDot 注册打点"}]}}]}}
