+## 头像库「是否默认」唯一化：`tt_user_avatar` 存量数据清洗
+
+**背景**：`tt_user_avatar.is_default` 的语义是「新用户 / 白号注册时分配的初始头像」，
+**全表必须最多只有一条 `is_default='1'`**。但后台「设置 → 头像管理」的开关写成默认时，
+后端只做了 `updateById`，没有把其他记录的默认标记清掉 ⇒ 库中一度累积出 **7 条默认**（id 63~69），
+`id=62` 反而是「否」。后果：后台看到一排「是」容易误解（用户 2026-09-24 反馈），
+且 C 端注册处（`ApiRegisterServiceImpl` / `PromoLoginServiceImpl`）用的是
+`list(is_default='1')` + `RandomUtil.choice(...)` **随机挑一条**，导致默认头像实际不唯一、每次注册拿到的都不同。
+
+**代码侧修复**（非 SQL，见 `docs/修改记录.md` 同日条目）：`TtUserAvatarServiceImpl`
+在 `updateUserAvatarById` / `saveAvatar` 中增加互斥逻辑 —— 任何把某条置为 `is_default='1'` 的写入，
+都先把其余记录清成 `'0'`，两步同一事务。
+
+**本次数据库变更 1 处**（2026-09-24 已在库 `henan` 执行）：把多余的默认标记收敛为**只保留 id 最小的一条**（id=63）。
+
+**变更 SQL**：
+
+```sql
+UPDATE `tt_user_avatar`
+   SET `is_default` = '0'
+ WHERE `is_default` = '1'
+   AND `id` <> (SELECT `min_id` FROM (
+         SELECT MIN(`id`) AS `min_id` FROM `tt_user_avatar` WHERE `is_default` = '1'
+       ) AS `t`);
+```
+
+> ⚠️ MySQL 不允许在 `UPDATE` 的子查询里直接查同一张表，故此处包了一层派生表 `t` 绕过；
+> 该写法的坑已记在 `.workbuddy/memory/` 当日日志里，后续同类 SQL 照此办理。
+
+**验证口径**：执行后 `SELECT is_default, COUNT(*) FROM tt_user_avatar GROUP BY is_default;`
+应当只有两行 —— `0 → N`（N = 总数-1）、`1 → 1`。

+- **头像管理：「是否默认」可同时多条为「是」的缺陷修复（唯一性约束 + 存量数据清洗 + 开关交互）**
+
+  **起因**：用户在「网站设置 → 头像管理」截图反馈，「是否默认」那一列有 7 条都显示绿色「是」，
+  而按语义**全站默认头像只应该有一条**。
+
+  **排查结论（逐层验证，不是猜的）**：
+
+  | 层 | 实测 | 结论 |
+  |---|---|---|
+  | 数据库 | `SELECT is_default, COUNT(*) ... GROUP BY is_default` → `0→1`、`1→7`（id 63~69） | **数据本身就错**，界面是忠实反映 |
+  | 前端 | `v-model="scope.row.isDefault"` 直读接口字段 | 无显示层问题，不需要改渲染 |
+  | 后端 | `TtUserAvatarServiceImpl.updateUserAvatarById` 只做 `updateById` | **根因**：设为默认时不互斥清空其他记录 |
+
+  ⇒ 定位为**后端写接口缺约束 + 存量脏数据**，不是 UI bug。
+
+  **二、连带发现（比表面问题更严重）**：C 端有 4 处消费「默认头像」，其中
+  `ApiRegisterServiceImpl`、`PromoLoginServiceImpl` 用的是
+  `list(is_default='1')` + `RandomUtil.choice(...)` **随机挑一条** —— 这是在「可能有多条默认」的
+  既成事实上打的补丁。后果是**每次注册拿到的初始头像都不一样**，默认头像形同虚设。
+  （`TtUserServiceImpl` 白号那边已有 `defaultAvatarList.isEmpty()` 的降级，逻辑本身没问题。）
+
+  **三、改动清单**
+
+  1. **后端互斥（核心）** `skins-service/service-admin`：
+     - `TtUserAvatarService` 新增 `saveAvatar(TtUserAvatar)`、`getDefaultAvatar()`；
+     - `TtUserAvatarServiceImpl` 新增私有方法 `clearOtherDefaultsIfNeeded(...)`：
+       凡是把某条写成 `is_default='1'` 的写入，**先 `UPDATE ... SET is_default='0' WHERE is_default='1' AND id<>当前id`**，
+       再落当前这条，两步同一事务（`@Transactional`）。只在确实要置默认时才执行 UPDATE，普通编辑不白扫全表。
+     - `updateUserAvatarById` / `saveAvatar` 均接入；顺手删掉原方法里无意义的 `setAvatar(getAvatar())`。
+  2. **控制器** `TtUserAvatarController.add` 由 `userAvatarService.save(...)` 改走 `saveAvatar(...)`，
+     使**新增**也受同一约束（原来新增一条默认就会叠加出第二个）。
+  3. **存量数据清洗**：`UPDATE tt_user_avatar SET is_default='0' WHERE is_default='1' AND id <> (最小 id 的默认)`，
+     实测影响 6 行，清洗后 `0→7 / 1→1`（保留 id=63）。SQL 全文见 `docs/updata_sql.md`。
+  4. **前端交互** `ruoyi-ui/src/views/skins/ttSetting/avatar.vue`：「是否默认」由 `updateUserStatus`
+     改走新的 `updateDefault(...)` —— 开启时先 `$confirm` 告知「原默认头像「xx」将自动取消默认」，
+     取消则回滚开关视觉并重新拉列表。关闭时直接保存。
+
+  **四、验证**：后端 `mvn -q -pl skins-service/service-admin -am install -DskipTests` 通过，
+  字节搜 `clearOtherDefaultsIfNeeded`/`saveAvatar`/`getDefaultAvatar` 均在 `.class` 里；
+  前端 `vue-cli-service build` 通过，新文案与新方法名均落在 `dist/static/js/chunk-cf2f9538.*.js`。
+
+  **五、踩坑**：MySQL **不允许 `UPDATE` 的子查询直接查同一张表**（报 1093），
+  解法是包一层派生表 `(SELECT MIN(id) ... ) AS t` 绕过 —— 后续同类 SQL 照此办理。
+
+  ⚠️ **待办**：后端 jar 未重打包、服务未重启，互斥逻辑**尚未在运行中的服务里生效**；
+  前端 `dist` 已就绪但线上资源需按部署流程发布。存量数据已清洗，界面当下已正确。

 - **幸运升级：水位配置从「4 档波段表」简化为「一个目标水位百分比」+ 饰品随机数区间恢复可编辑**
 
   **起因**：上一版后台要维护一张 4 档波段表（水位下界/上界 × 随机数下界/上界 = 16 个数），

   这是「水位是累计比例」的必然结果 —— 想在大水位下也能快速纠偏，要调 **`gain`**（水位每偏离 1 个点、
   中心移动的幅度；现在默认 2，暂未在后台暴露），或者直接人工注水/抽水。
 
+- **后台开关（el-switch）统一为「文字 = 当前值」口径，修掉反向文字露底色的误导**
+
+  **起因**：用户反馈「头像管理」的**状态**与**是否默认**两列看得费解。查下来是两个叠加问题：
+
+  1. **两边文字显示规则相反**。element-ui 的 `el-switch` 里 `active-text` 渲染在**右**侧、
+     且只在**开启时**显示；`inactive-text` 渲染在**左**侧、只在**关闭时**显示。
+     本页「状态」用的是 `inactive-text="启用"`（把当前值放在左侧），
+     「是否默认」用的是 `active-text="是"`（把当前值放在右侧）—— 同一张表里两套相反的读法。
+  2. **更糟的是反向文字会露出底色**。「状态」列开启时左侧露出绿色底 + 白字「启用」，
+     点一下滑块滑到左边、绿底被盖住，可读文字变成「停用」。两列的滑块方向可以完全相反，
+     同一行的绿白视觉还不一样（`is-checked` 与背景色是两套独立配色）。
+
+  ⇒ **定的新口径（全后台统一）：`inactive-text` = 关闭时的值，`active-text` = 开启时的值，
+  也就是「文字显示的就是当前值」，滑块停在哪边、哪边的文字就是现在的结果。**
+  颜色同步收敛为与 `active-value`/`inactive-value` 同侧：**绿 = 该项生效、红 = 该项未生效**。
+
+  **改动清单（7 个文件，15 处开关）**
+
+  | 文件 | 列 / 字段 | 调整 |
+  |---|---|---|
+  | `skins/ttSetting/avatar.vue` | 状态 `status` | 文字翻正（启用/停用），配色与 `active-value` 同侧 |
+  | `skins/ttSetting/avatar.vue` | 是否默认 `isDefault` | `active/inactive-value` 翻正为 `1/0`（= 与 `initData`、弹窗单选按钮一致），文字归右侧 |
+  | `skins/ttuser/index.vue` | 帐号状态 `status` | `active/inactive-value` 翻正为 `0/1`（原为 `1/0`，是全局唯一的反向异类） |
+  | `skins/ttuser/index.vue` | 提货状态 `deliveryStatus` | 同上翻正（`1` = 已禁用提货） |
+  | `skins/ttuser/index.vue` | 赠送状态 `giftStatus` | 同上翻正（`1` = 已禁用赠送） |
+  | `skins/ttBonus/index.vue` | 启用状态 `status` | 文字从「是/否」改为「启用/禁用」并翻正 |
+  | `skins/ttBox/boxType.vue` | 是否对战类型 `isFightType`、是否显示 `isShow` | label 归位；`isShow` 的 `active/inactive-value` 翻正为 `1/0` |
+  | `skins/ttredPacket/index.vue` | 是否启用 `useStatus` | `active/inactive-value` 翻正为 `1/0`，配色同侧 |
+  | `skins/ttUpgrade/index.vue` | 状态 `status` | `active/inactive-value` 翻正为 `0/1`（原为 `1/0`）+ 文字翻正 |
+  | `skins/ttBox/index.vue` | 弹窗内 是否对战宝箱 `isFight`、宝箱状态 `status`、是否首页推荐 `isHome` | 文字归位、`isFight`/`status` 的 `active-value` 翻正 |
+
+  **关键约束：以上全部只是「值 ↔ 显示」的映射调整，`active-value` 与 `inactive-value` 成对同翻，
+  提交给后端的字段值逐字节不变，数据库语义与接口契约零改动**（各页 `@change` 都是把整个 row/form
+  原样 `PUT` 出去，不做值转换）。
+
+  **语义校对依据**（改前逐个确认过，避免把含义改反）：
+  - `tt_user_avatar.status` 与 `tt_user.status`：`UserStatus` 枚举 = `OK("0","正常")` / `DISABLE("1","停用")`，
+    `ApiUserDetailsServiceImpl` 对 `DISABLE` 直接拒登并踢线 ⇒ **`0` = 启用**。
+  - `tt_user_avatar.is_default`：`TtUserAvatar` 的 `@Excel(readConverterExp = "0=否,1=是")`，
+    且注册 / 白号 / 登录三处均查 `is_default = '1'` 取默认头像 ⇒ **`1` = 是**。
+  - `tt_user.delivery_status` / `gift_status`：实体注释 + 业务代码均为 **`1` = 已禁用**（`"1".equals(...)` 返回"已被禁用"提示）。
+  - 可对照的既有正确写法：`ttSetting/banner.vue`、`ttRechargeList/index.vue`、`ttuser/userPack.vue`。
+
+  ⚠️ **踩坑**：用户截图里「是否默认」列显示为**红底白字「否」**容易被误读成"开着"。
+  那是 `active-color`/`inactive-color` 与 `active-text`/`inactive-text` 配成反的典型症状 ——
+  改完须确认**颜色所在的半边和文字所在的半边是同一半**。
+
+  ⚠️ **未改（故意留着）**：`ttRoll/officialRollConfig.vue` 的状态开关用的是
+  `:value="scope.row.status === '0'"` + 无文字标注的正向布尔（绿=开），本身自洽；
+  只建议后续补一个文字标注。
+
+- **管理后台：3 个页面表格右侧留白（「表格没有平铺完整」）**
+
+  **起因**：用户反馈「管理后台有些页面的表格没有平铺完整」。追问确认现象是
+  **表格右侧留一条空白**（不是列错位、也不是横向滚动条）。
+
+  **根因**（读 Element 源码定论）：`element-ui/packages/table/src/table-layout.js:132-195`
+  的 `updateColumnsWidth()` ——
+
+  ```
+  flexColumns = 所有「width 不是数字」的列（含显式 min-width 列、以及两者都没写的列）
+  if (flexColumns.length > 0 && fit)  → 自动分配，表格撑满 bodyWidth        （第 145 行）
+  else                                → bodyWidth = Σ(width || minWidth || 80)（第 182-194 行）
+  ```
+
+  ⇒ **只要有一列写了 `min-width`（或宽度两者都不写），表格就会自动撑满容器；
+  但当所有列都是固定 `width` 时，表格宽度恒等于列宽之和 —— 容器再宽也不拉伸，右侧就空一条。**
+
+  同一份源码里还有个易漏的点：`type="selection" / "expand" / "index"` 在未写 width 时，
+  由 `config.js:3-26` 的 `cellStarts` 给死 **48px 固定宽**，**不参与弹性分配** ——
+  所以「展开列 + 其余全固定宽」的表格同样会留白。
+
+  **扫描结论**（115 个顶层表格，1920 视口下容器可用 1584px）：
+
+  - **仅 6 个**是全固定列（会留白）；**109 个**含弹性列、会自行撑满。
+  - **0 个**会出横向滚动条（判据：`Σwidth + Σmin-width > 容器`）。
+  - 留白量**随屏幕变宽而增大**（2560 视口下最大 1854px）—— 这正是"没平铺完整"的典型特征。
+
+  **改动清单（3 个页面主表格，各把「内容最长的固定列」改为 `min-width`）**
+
+  | 文件 | 列 | 调整 | 表格宽 → 结果 |
+  |---|---|---|---|
+  | `skins/blankCardKey/index.vue` | 卡密编码 `cardCode` | `width="200"` → `min-width="200"` | 1000 → 撑满（原留白 584px） |
+  | `system/role/index.vue` | 权限字符 `roleKey` | `width="150"` → `min-width="150"` | 1075 → 撑满（原留白 509px） |
+  | `game/wheel/records/index.vue` | 投注符号 `betSymbols` | `width="140"` → `min-width="140"` | 1368 → 撑满（原留白 216px） |
+
+  选列理由：卡密编码是 32 位等宽字符 + 复制按钮、权限字符内容最长且**已带 `show-overflow-tooltip`**
+  （加宽无副作用）、投注符号是拼接字符串、长度波动最大 —— 都是"多给宽度只有好处"的列。
+  三处均加注释说明「为什么必须是 min-width」，防止后来人按"列宽统一用 width"的惯例改回去。
+
+  **未改（用户明确不动）**：3 个展开行内嵌明细表（`wheel/records` 下注明细、
+  `delivery/transferApply` 与 `transferApplyProcessed` 的饰品明细）与 1 个弹窗内倍率表
+  （`wheel/config`，固定 `width:640px`）—— 它们宽度受容器约束是设计意图。
+  其中 `transferApply` / `transferApplyProcessed` 声明了 `style="width: auto"` 却只有 2 列固定宽
+  （300+120=420），**在展开行里只占 420px**；若后续要铺满，改其中一列为 `min-width` 即可。
+
+  **验证**：
+  - 编译产物断言：`vue-template-compiler` 编译 3 个页面，✓ 全部通过，
+    `min-width` 各 1 个（200 / 150 / 140），其余列仍为固定 width。
+  - 算法级回归：复现 `updateColumnsWidth` 后，
+    **1280 / 1440 / 1600 / 1920 / 2560 五个视口下 3 个主表格留白全部归零**。
+  - dev server 起来后 `curl` 返回 200，确认改动未破坏编译。
+  - ⚠️ **本机无法真机截图核对**：助手拉起 Chrome 被安全策略拦（连带报 `wsl.exe` 在程序黑名单），
+    故本次验证口径是「读源码 + 复现算法 + 编译产物断言」，**未经浏览器实测**。
+
+  **纯前端改动，不涉及数据库与接口**；`dist` 未发布。
