+# 半自动模式说明
+
+> 永期（永续 + 期权）专用。期期模式不可用。  
+> 与「手动开一组」（测试按钮）无关：半自动是**人工定看法并授权 → 机器盯开盯平 → 平完停**。
+
+---
+
+## 1. 流程
+
+```text
+系统设置开启半自动
+    → 首页出现「半自动 · 本单」面板
+    → 人工设：方向 / 波动点数 / 净利基数 / 选约门槛
+    → 「授权开下一单」
+    → 机器：选约 → 开仓 → 盯出场 → 双腿全平
+    → phase=wait_human，清授权，不自动开下一单
+    → 人工再授权才进入下一单
+```
+
+| 阶段 | 含义 |
+|------|------|
+| `wait_human` | 未授权，不开仓；有仓仍可盯平 |
+| 授权后 `idle`/`opening`/`open` | 与全自动相同状态机，但出场走半自动规则 |
+| 平仓后 | 强制回 `wait_human`，`semi_armed=false`，清本单出场锁 |
+| 进程重启 | 无仓时清 `semi_armed`，须重新授权 |
+| 开仓成功 | 锁定本单 `view/点数/净利基数`（持仓期不跟设置漂移） |
+
+安全门：选约异步后、落 `opening` 前再次校验授权；取消授权可中止未成交开仓。LIVE 授权前过 `live_ready`。关闭/开启半自动设置时强制清授权。
+
+---
+
+## 2. 方向（看法）
+
+| 看法 | 期权 | 永续 |
+|------|------|------|
+| 多 (`long`) | 买 Call | 空 |
+| 空 (`short`) | 买 Put | 多 |
+
+选约强制：**实值或平值**；最短剩余小时、最低杠杆用半自动本单参数（默认 ≥30h、杠杆 ≥100）。
+
+---
+
+## 3. 出场
+
+净利口径与全自动一致：可平盘口估价 − 开仓费 − 预估平仓费（非乐观 mark）。
+
+| 规则 | 条件 | close_reason |
+|------|------|----------------|
+| 顺方向 | 指数相对**开仓指数**达到目标点数，**且**组合净利 > 0 | `semi_target_points` |
+| 逆方向 / 兑现 | 组合净利 ≥ `semi_perp_exit_unit × k`（k=以损倍数，手动仓视为 1） | `semi_perp_exit` |
+
+- 到点但净利 ≤ 0：继续持有（状态提示，不平）。  
+- 流动性不足：进入 `liquidity_wait`；回落未达标则取消挂起。  
+- 半自动平仓**禁止**远虚「只平永续、期权归档」；顺序仍为**先期权后永续**。
+
+首页预览「指数 → 到点」用**当前指数**示意；真实触发达标用**开仓指数**。
+
+---
+
+## 4. 设置键
+
+| Key | 默认 | 说明 |
+|-----|------|------|
+| `semi_auto_enabled` | false | 系统设置 · 节奏 |
+| `semi_armed` | false | 是否已授权本单（平完清零） |
+| `semi_view_side` | long | long / short |
+| `semi_option_move_points` | 50 | 顺向波动点数 |
+| `semi_perp_exit_unit` | 5 | 净利出场基数（×k） |
+| `semi_min_option_hours` | 30 | 选约最短剩余 |
+| `semi_min_option_leverage` | 100 | 选约最低杠杆 |
+
+API（需登录）：
+
+- `POST /api/plan/semi/arm` `{ "armed": true|false }`
+- `PUT /api/plan/semi/params` 本单参数（有持仓 409）
+
+---
+
+## 5. 中控
+
+Fleet `strategy` 透出半自动字段。监控模式列在永期开启半自动时显示「半自动」；详情状态含授权/方向，出场列显示点数与净利目标。
+
+---
+
+## 6. 与全自动差异
+
+| | 全自动 | 半自动 |
+|--|--------|--------|
+| 方向 | 盘口信号或固定方向 | 人工看法 |
+| 出场 | fixed_usdt / 权利金倍数（可锁定） | 点数+净利>0，或基数×k |
+| 轮间 | 休息后自动再开 | 平完停，须再授权 |
+| 期期 | 可用 | 强制关闭半自动 |

+
+## 轮次
+
+| 轮次 | 工具 | 结论 |
+|------|------|------|
+| 1 | Security Review | 3 项中高：取消授权 TOCTOU、出场参数未锁定、关半自动未清 armed |
+| 2 | Bugbot | 2 项高：重启后陈旧 armed、授权绕过 LIVE `live_ready` |
+
+## 已修复
+
+1. 选约后、`opening` 前、以及 `open_group` 直前再次校验 `semi_armed`；取消授权中止开仓。  
+2. `phase=opening` 时禁止取消授权（防 LIVE 落单窗口 TOCTOU）。  
+3. 开仓成功写入 `semi_trade_lock`；盯盘出场读锁；平仓/收尾清理。  
+4. 设置关/开半自动强制 `semi_armed=false`；设置接口不可写入 `semi_armed`。  
+5. 进程启动无仓清 armed。  
+6. `arm_semi` LIVE 先过 `live_ready`。  
+7. 已授权或活跃阶段禁止改本单参数。  
+8. 半自动平仓禁止远虚只平永续；平仓后勿覆盖 `wait_human` phase。
+
+## 复审
+
+| 轮次 | 工具 | 结论 |
+|------|------|------|
+| 复审 Security | 先验 MEDIUM（opening→open_group 窗口） | 已用 `open_group` 直前 `is_armed` + `phase=opening` 禁止取消授权关闭 |
+| 复审 Bugbot | 同窗口 TOCTOU（high） | 同上已修；无其它半自动逻辑 bug |
+
+## 验证
+
+- `pytest backend/tests/test_semi_auto.py`：通过。  
+- 授权 API 仍 `require_user`；Fleet 仅只读字段。
+
+## 残留风险（可接受）
+
+- 授权后至开仓完成前改系统级非半自动参数（如杠杆）仍可能影响定仓；与全自动一致，非半自动独有。  
+- 有仓重启保留 trade_lock；无仓清 armed 后须重新授权。
