 # Changelog

+## alpha 0.6.3.1015
+
+- Replace instant personal lottery tickets with one persistent multiplayer
+  lottery round per group: start, register/update, status, draw, and cancel.
+- Treat each ticket as three distinct digits from 0-9. Sort digits before
+  storage so `347` and `743` represent the same selection.
+- Accept spaced and compact OCR forms. Ticket stakes are 1-500 coins with a
+  default of 10 when omitted.
+- Return 0%, 50%, 120%, or 300% of the stake for matching zero, one, two, or
+  three drawn digits. All settlement values remain integer coins.
+- Commit entry updates, stake differences, all-player payouts, cancellation
+  refunds, and event replay responses in serialized SQLite transactions.
+- Raise the blackjack stake range to 1-500 coins.
+- Add per-game personal sequence numbers and `/游戏记录` (`/gamehistory`) for
+  prize draws, lottery rounds, and blackjack hands.
+- Prefix game output with the configured player label and game number, such as
+  `Jacky #1：...`; aliases share the same counter and account.

+# alpha 0.6.3.1015 多人彩票与游戏记录
+
+## 一把彩票怎么玩
+
+1. 任意群友发送 `/彩票 开始`。发起人是本轮主持人。
+2. 每个人发送 `/彩票 报名 3 4 7 100`，表示选择 3、4、7，下注 100
+   金币。也可简写为 `/彩票347100`；省略金额时默认下注 10。
+3. 发送 `/彩票 当前状态` 查看本轮主持人、报名人数、每个人的号码和下注。
+4. 主持人发送 `/彩票 开奖`。机器人从 0～9 中抽取三个互不重复的数字，
+   统一排序后结算。
+5. 主持人也可在开奖前发送 `/彩票 取消`，所有报名者全额退款。
+
+命令关键词和数字之间的空格均可省略。`/买彩票` 和 `/lottery` 保留为
+对应别名。
+
+## 选号与报名
+
+- 每张票必须是三个互不重复的 0～9 数字。
+- 数字顺序不影响结果：`347`、`743` 和 `3 4 7` 都保存为 `3 4 7`。
+- 每人每把只有一张票。再次报名会更新号码和下注，不增加个人局号。
+- 更新到更高下注时只补扣差额；降低下注时退回差额。
+- 下注范围是 1～500，省略时为 10。
+- 没有进行中的彩票时不能报名；没有报名者时不能开奖。
+- 只有创建本轮的主持人可以开奖或取消，状态查询对群内所有人开放。
+
+支持的报名示例：
+
+```text
+/彩票 347
+/彩票 743 100
+/彩票 报名 3 4 7 100
+/彩票报名347金额100
+/彩票347100
+/lottery join 347 100
+```
+
+## 返还规则
+
+报名时先扣除下注。开奖号和玩家号码按集合比较，返还包含本金：
+
+| 命中数 | 返还 |
+|---|---:|
+| 0 个 | 0% |
+| 1 个 | 50% |
+| 2 个 | 120% |
+| 3 个 | 300% |
+
+金币只使用整数；百分比计算的小数部分向下取整。例如下注 100，命中两个
+返还 120，净变化为 `+20`。
+
+## 个人局号与记录
+
+抽奖、彩票和 21 点分别维护本人的游戏局号。第一次参与某种游戏显示
+`Jacky #1：...`，下一把显示 `Jacky #2：...`。配置别名解析到同一人物时，
+共用同一账户、局号和历史。
+
+发送 `/游戏记录 [页码]`、`/个人记录 [页码]` 或
+`/gamehistory [page]` 查看最近记录，每页五条。记录包含游戏、个人局号、
+结果、下注、返还和净变化，最多保留最近 50 条。
+
+21 点下注范围同步调整为 1～500。`/21点 开始 100` 只表示本局下注 100；
+发牌后再单独发送 `/21点 要牌` 或 `/21点 停牌`。
+
+## 持久化与并发
+
+彩票轮次、报名和结算保存在 Edge SQLite。报名/改注、所有玩家的开奖返还、
+取消退款和事件重放响应都在 `BEGIN IMMEDIATE` 事务中提交。重复事件不会
+重复扣款、发奖或增加局号；进程重启后未开奖轮次和个人记录仍然保留。
