+# 控糖消消乐平台接入说明
+
+## 已接入能力
+
+- 复用主小程序 `token` 与微信小程序登录，不创建第二套游戏账号。
+- 按周一日期、性别自动分配最多 7 人的同行组。
+- 以真实平台昵称、头像、认糖数和本周最高分排序。
+- 每局用 `session_key` 上报绝对进度，断网重试不会重复加分。
+- 待同步成绩最多本地保留 8 局，重新联网后自动补传。
+- 微信好友与朋友圈分享使用随机分享码，不在链接中暴露用户 ID。
+- 受邀进入只记录一次轻量分享访问，不自动建立家庭或好友绑定。
+
+## 接口
+
+- `GET /api/tcm/gameWeeklyLeaderboard`：获取或创建当前周同行榜。
+- `POST /api/tcm/gameSubmitProgress`：上报 `session_key`、`learned_count`、`score`、`ended`。
+- `POST /api/tcm/gameRecordShare`：记录分享动作并获取本周分享码。
+- `POST /api/tcm/gameAcceptShare`：受邀用户登录后提交 `invite_code`。
+
+四个接口都使用现有 `LoginMiddleware` 校验主小程序 `token`。
+
+## 部署顺序
+
+1. 执行 `server/sql/1.9.20260717/add_tcm_endless_game_platform.sql`。
+2. 发布 `server/app/api/logic/tcm/GamePlatformLogic.php` 和 `TcmController.php`。
+3. 重新构建并上传小程序前端。
+
+如果后端或数据表尚未发布，游戏仍可离线游玩，榜单会显示“离线记录中”；联网且接口可用后自动补传。
+
+## 上线前检查
+
+- 用男女各两个测试账号进入，确认被分入对应性别组。
+- 同一局重复提交相同 `session_key`，确认周认糖数不重复增加。
+- 断网完成几次消除，再联网打开榜单，确认成绩补传。
+- 分享给另一个微信账号，确认能直接进入游戏且链接中没有用户 ID。
+- 周一验证新周重新分组，旧周成绩不带入新周。
