-2. 是否有更简单、更容易执行和对账的分红设计？
-
-并给出推荐方案与落地路径。

-## 2. 当前分红设计现状（按代码实际行为）
+## 2. 总体结构（两层 + 树形）
 
-## 2.1 配置层面（看起来是三级）
+分红分为两个明确步骤：
 
-历史上后台有三处比例字段（其中后两项已下线）：
+### A. 一级：渠道结算（平台 → 渠道）
 
-- `channel`：渠道分红参数（`turnover_share_rate`、`affiliate_*` 等）
-- `admin_group`：角色组 `commission_rate`（已删除）
-- `admin`：管理员 `commission_rate`（已删除）
+- 按渠道配置的 `agent_mode` 计算本期 **渠道总佣金**：
+  - **turnover（流水/返水）**：基数 = 已结算注单总投注，佣金 = 总投注 × `turnover_share_rate`
+  - **affiliate（联营）**：基数 = 平台盈亏扣成本后金额，佣金 = 基数 × 阶梯占成
+- 统计范围：`bet_order.status = 2`（已结算），周期为 **上次结算结束时间 ~ 本次结算时刻**
+- 产出：`agent_settlement_period`（结算周期快照）
 
-从“配置界面”角度，容易被理解为：  
-**渠道比例 -> 角色组比例 -> 管理员比例** 的三级链路。
+### B. 二级：代理树拆分（渠道总佣金 → 各管理员实得）
 
-## 2.2 结算层面（实际执行是单层）
+- **不再**在渠道管理页维护「渠道内管理员分配比例」（`channel_admin_share` 已废弃于 UI，历史表可保留）
+- 在 **管理员管理**（`/admin/auth/admin`）维护代理树：
+  - `parent_admin_id`：上级代理（顶级留空）
+  - `commission_share_rate`：从 **上级本期分红** 中抽取的比例（%），仅子代理需要填写
+- 结算时由 `AdminCommissionDistributionService` 递归拆分：
+  1. 渠道总佣金先进入该渠道 **顶级代理**（`parent_admin_id` 为空）
+  2. 每个代理按直属子代理的 `commission_share_rate`，从 **自己拿到的金额** 中划出子代理份额
+  3. **上级保留** = 自己拿到的金额 − 已分给所有子代理的金额
 
-当前手动结算逻辑在 `Channel` 控制器中：
+**示例**（上级本期拿到 3000）：
 
-- 按渠道下注汇总计算 `total_bet_amount / platform_profit_amount`
-- 根据 `channel.agent_mode` 计算佣金基数与佣金比例
-- 生成 `agent_settlement_period` 与 `agent_commission_record`
+| 子代理 | 配置比例 | 实得 |
+|--------|----------|------|
+| 子代理 A | 20% | 600 |
+| 子代理 B | 40% | 1200 |
+| 上级自身 | — | 1200（3000 − 600 − 1200） |
 
-关键点：**佣金记录只写了一条 admin_id（渠道下首个管理员）**，并未按角色组/管理员比例拆分多条佣金明细。  
-也就是说，目前“角色组比例、管理员比例”主要在新增/编辑时做约束校验，但**没有进入最终结算分账公式**。
+若子代理还有下级，在其 **实得金额** 上继续按同样规则向下拆分。

-## 3. 当前方案对甲方可理解性的评估
+## 3. 配置入口与权限
 
-结论：**一般不容易看懂，且容易产生“配置了却不生效”的认知落差。**
+| 能力 | 入口 | 说明 |
+|------|------|------|
+| 渠道分红参数 | `/admin/channel` | `agent_mode`、返水/联营比例、结算周期等 |
+| 代理树与分红比例 | `/admin/auth/admin` | 树形列表；配置上级代理、分红比例、渠道归属 |
+| 渠道筛选 | 管理员列表公共搜索 | 超管可按渠道筛选 |
+| 数据可见范围 | 管理员列表 | 非超管仅见 **本人 + 全部下级**，不见其他代理线 |
+| 结算执行 | `/admin/channel` 手动结算 / 定时任务 | **仅超管**可结算；结算即发放至 `admin_wallet` |
 
-主要原因：
+### 3.1 子代理分红比例校验
 
-1. **心智复杂**：甲方要同时理解渠道模式（返水/联营）、角色组比例、管理员比例三层规则。
-2. **口径不一致**：界面上有三级比例，但结算时是渠道单层落账，容易质疑“为什么不是按我配的三级比例发放”。
-3. **对账难**：财务看到佣金记录时只能看到渠道维度，不容易反推角色组和管理员分配关系。
-4. **运维负担高**：层级变化（调组、换管理员）后，历史解释成本高。
+- 同一 `parent_admin_id` 下，所有启用子代理的 `commission_share_rate` **合计不得超过 100%**
+- 创建/编辑子代理时，表单会提示 **当前剩余可分配比例**
+- 若合计为 100%，上级在本层 **不再保留分红**
+- 顶级代理（无上级）**不需要**填写 `commission_share_rate`
+
+### 3.2 角色组的作用
+
+- `admin_group` **只负责**菜单权限、数据范围、角色隔离
+- **不参与**金额运算

-## 4. 更简单的分红设计方式（推荐）
+## 4. 结算执行流程
 
-## 4.1 推荐方案：`渠道结算 + 渠道内二次分配`（两层）
+1. 超管触发渠道结算（手动或 `ChannelAutoSettleTicker` 周期任务）
+2. `ChannelSettlementService::buildSettlePayload` 汇总注单并计算渠道总佣金
+3. `AdminCommissionDistributionService::distributeChannelCommission` 按代理树拆分各管理员实得
+4. 事务内写入：
+   - `agent_settlement_period`（`status = 2` 已完成）
+   - 多条 `agent_commission_record`（每个实得 > 0 的管理员一条，`status = 1` 已发放）
+   - `AdminWalletService::creditCommission` → `admin_wallet` + `admin_wallet_record`（`biz_type = commission_income`）
+5. 渠道 `carryover_balance` 重置为 0（超管结算即发放，不再保留渠道待分红池）
 
-将分红流程拆为两个明确步骤：
-
-### A. 一级：渠道结算（平台对渠道）
-
-- 保留当前 `channel.agent_mode` 的计算方式（turnover/affiliate）
-- 先得到一个渠道应发佣金：`channel_commission_amount`
-- 生成渠道结算单（当前已具备）
-
-### B. 二级：渠道内分配（渠道对管理员）
-
-- 不再使用“角色组分红比例”参与金额运算（角色组只负责权限）
-- 仅维护“渠道下管理员分配权重”（例如总和=100%）
-- 自动拆分：`admin_commission = channel_commission_amount × admin_weight`
-- 为每个管理员生成独立佣金记录（多条）
-
-> 这样甲方只需要理解一句话：  
-> **平台先算渠道总佣金，再按渠道内管理员权重拆分。**
-
-## 4.2 为什么推荐该方案
-
-1. **业务更直观**：甲方看“渠道总佣金 + 管理员占比”即可。
-2. **和现有代码贴近**：你们当前已经是“先算渠道佣金”，只需补“二次拆分”。
-3. **对账容易**：每个管理员佣金来源清晰，可直接汇总对账。
-4. **后续可扩展**：以后要按团队、按代理线拆分，可以在“二次分配”层升级，不影响一级结算。
+**前置条件**：渠道下须存在至少一名 **顶级代理**（`channel_id` 匹配且 `parent_admin_id` 为空）；否则结算失败并提示「渠道未配置顶级代理管理员」。
 
 ---
 
-## 5. 备选方案对比
+## 5. 给甲方/运营的话术（推荐）
 
-## 5.1 方案A（现状表象）：渠道 -> 角色组 -> 管理员三级
-
-- 优点：理论上精细
-- 缺点：配置理解成本高、维护复杂、容易和实际结算脱节
-- 适用：组织结构非常稳定、财务系统成熟的大盘
-
-## 5.2 方案B（推荐）：渠道 -> 管理员两级
-
-- 优点：简单、易讲、易对账、改造成本低
-- 缺点：若强依赖“角色组抽成”会减少一层表达
-- 适用：当前阶段（快速上线、减少运营误解）
-
-## 5.3 方案C（最简）：仅渠道一级
-
-- 优点：最简单
-- 缺点：无法直接落地到管理员收益，不利于激励
-- 适用：仅用于统计，不用于发佣
+1. **渠道分红**：系统按渠道模式（返水或联营）自动计算该周期 **渠道总佣金**（基于玩家已结算注单，**不是**按充值金额）。
+2. **人员分配**：总佣金进入渠道顶级代理后，按 **管理员管理中配置的上下级与分红比例** 自动向下拆分；上级只保留分给下级后的余额。
+3. **角色组**：仅管权限，不管分钱。
+4. **结算可追溯**：每条 `agent_commission_record` 可关联 `agent_settlement_period`；钱包流水 `commission_income` 可反查佣金记录。

-## 6. 建议的产品口径（给甲方的话术）
+## 6. 核心数据字段
 
-建议统一说明为：
+| 表/字段 | 作用 |
+|---------|------|
+| `channel.agent_mode` / `turnover_share_rate` / `affiliate_*` | 渠道总佣金计算参数 |
+| `admin.parent_admin_id` | 上级代理 |
+| `admin.channel_id` | 所属渠道 |
+| `admin.commission_share_rate` | 从上级分红抽取比例（%），顶级为空 |
+| `agent_settlement_period` | 结算周期与大盘快照 |
+| `agent_commission_record` | 各管理员本期实发佣金 |
+| `admin_wallet` / `admin_wallet_record` | 管理员钱包与入账流水 |
 
-1. **渠道分红**：系统按渠道配置（返水或联营）自动计算该周期渠道总佣金。
-2. **人员分配**：渠道总佣金按“渠道内管理员分配比例”自动拆分。
-3. **角色组作用**：角色组只负责菜单权限与数据权限，不参与金额运算。
-4. **结算可追溯**：每条管理员佣金都能追溯到对应渠道结算单。
+> **历史表** `channel_admin_share`：2026-04-18 曾用于「渠道内 flat 100% 拆分」，2026-05-29 起结算改走代理树，后台入口已移除，请勿再依赖该表配置。

-## 7. 数据与实现改造建议（按最小改动）
+## 7. 相关代码
 
-## 7.1 数据字段建议
-
-- 保留：`channel` 的分红计算参数（现有）
-- 建议新增（任选其一）：
-  - 在 `admin` 增加 `channel_share_rate`（该管理员在所属渠道的拆分比例）
-  - 或新增 `channel_admin_share(channel_id, admin_id, share_rate)`
-
-## 7.2 逻辑改造建议
-
-1. 渠道结算得到 `commission_amount`
-2. 拉取该渠道有效管理员分配比例列表（总和=100%）
-3. 按比例拆分并批量写入 `agent_commission_record`
-4. 若分配比例未配置：
-   - 方案一：默认100%给渠道负责人
-   - 方案二：阻止结算并提示“请先配置渠道管理员分配比例”
-
-## 7.3 风险控制建议
-
-- 分配比例总和强校验（必须=100%）
-- 管理员离职/禁用时自动重算或禁止结算
-- 结算后锁单，后改比例不影响历史账单
+| 模块 | 路径 |
+|------|------|
+| 渠道结算 | `app/common/service/ChannelSettlementService.php` |
+| 树形拆分 | `app/common/service/AdminCommissionDistributionService.php` |
+| 管理员 CRUD / 校验 | `app/admin/controller/auth/Admin.php` |
+| 管理员前端 | `web/src/views/backend/auth/admin/` |
+| 自动结算 | `app/process/ChannelAutoSettleTicker.php` |

-## 8. 迁移策略建议
-
-分三步上线：
-
-1. **第1步（兼容期）**：保留现有字段，新增“渠道内管理员分配比例”配置
-2. **第2步（双轨期）**：结算时同时产出“旧口径结果 + 新口径预览”用于核对
-3. **第3步（切换期）**：正式切到“渠道+管理员两级”，角色组比例仅保留展示或下线
-
----
-
-## 9. 最终建议结论
-
-从“甲方能否看懂”和“系统可维护性”来看，建议采用：
-
-**渠道结算 + 渠道内管理员二次分配（两级）**。
-
-这是在你们当前代码基础上改造成本最低、解释成本最低、财务对账最清晰的方案。  
-不建议继续强化“渠道->角色组->管理员”三级分红公式作为主线。
-
----
-
-## 10. 本次已落地改造（2026-04-18）
-
-已在系统中完成以下改造：
-
-1. 新增渠道管理员分配表：`channel_admin_share`
-2. 下线并删除旧字段：`admin_group.commission_rate`、`admin.commission_rate`
-3. 新增后台接口：
-   - `channelAdminShareList`：读取渠道管理员分配配置
-   - `saveChannelAdminShare`：保存渠道管理员分配配置（启用项合计必须100%）
-4. 手动结算改造：
-   - 先算渠道总佣金
-   - 再按 `channel_admin_share` 比例拆分为多条 `agent_commission_record`
-   - 结算预览支持查看拆分明细
-5. 渠道后台页面新增“分配比例”按钮与配置弹窗，用于维护管理员分配比例
-6. 角色组与管理员页面已移除旧分红比例字段展示与编辑项
-
-说明：
-- 若未配置 `channel_admin_share`，系统会回退为“渠道首个管理员100%”以保证兼容历史流程。
+## 8. 变更记录
 
+| 日期 | 说明 |
+|------|------|
+| 2026-04-18 | 落地 `channel_admin_share` 渠道内 flat 拆分；移除 `admin`/`admin_group.commission_rate` |
+| 2026-04-23 | 超管结算即发放至管理员钱包；新增 `admin_wallet` 体系 |
+| 2026-05-29 | **改为代理树形分红**：配置迁移至管理员管理 `commission_share_rate` + `parent_admin_id`；移除渠道页分配比例入口；管理员列表树形展示与下级可见范围 |
