+## 2026-06-03 Public Gallery ViewModel 收口
+
+- 背景：`RpgEntryHomeView.tsx` 巨型页面内混合了公开作品分类、跨来源去重、搜索归一化、作品号匹配、时间戳解析和排序规则，新增玩法时页面与 ViewModel 规则容易纠缠。
+- 决策：新增 `src/components/rpg-entry/rpgEntryPublicGalleryViewModel.ts`，把 `buildPublicGalleryCardKey`、`buildPublicCategoryGroups`、`getPlatformPublicEntries`、`getAllPlatformPublicEntries`、`getPlatformSearchableWorkIds`、`filterPlatformWorkSearchResults`、`isExactPublicWorkCodeSearch`、`filterTodayPublishedEntries`、公开卡片指标 getter、`buildPlatformRankingEntries`、`getPlatformRankingMetricValue`、`getPlatformCategoryKindFilter`、`matchesPlatformCategoryKindFilter`、`sortPlatformCategoryEntries`、`getPlatformCategoryPrimaryMetric`、`parsePlatformEntryTimestamp` 和 `getPlatformWorldTimestamp` 收口为公开作品 ViewModel Interface。公开作品 key 复用平台入口身份规则，补齐 jump-hop / wooden-fish 等玩法区分。
+- 影响范围：RPG 首页公开作品发现、分类、搜索、排行数据准备，以及后续新增玩法公开卡片接入。

 ## 2026-06-03 最近创作只复用创作模板入口
 
 - 背景：底部加号创作入口的“最近创作”最初由真实作品架摘要驱动，但页面曾按作品标题、摘要和生成状态渲染独立最近创作卡，和其它模板页签的卡片样式及点击语义不一致。

+# 【前端架构】Public Gallery ViewModel 收口计划
+
+## 背景
+
+`RpgEntryHomeView.tsx` 同时承担首页、发现、分类、排行、搜索和公开作品卡片渲染。公开作品的 category 分组、跨来源去重、搜索归一化、作品号匹配、时间戳解析和列表排序原本都放在页面巨型 **Implementation** 中，导致公开作品规则与 JSX 交错，新增玩法时难以判断该改页面、卡片还是平台入口规则。
+
+## 决策
+
+新增 `src/components/rpg-entry/rpgEntryPublicGalleryViewModel.ts`，作为公开作品 ViewModel **Module**。该 **Module** 的 **Interface** 收口为：
+
+- `buildPublicGalleryCardKey(entry)`：复用平台公开作品身份规则，补齐 jump-hop / wooden-fish 等玩法 key。
+- `buildPublicCategoryGroups(featuredEntries, latestEntries)`：统一去重、标签兜底和分类排序。
+- `getPlatformPublicEntries(featuredEntries, latestEntries)` / `getAllPlatformPublicEntries(featuredEntries, latestEntries)`：统一公开作品合并规则。
+- `getPlatformSearchableWorkIds(entry)`、`filterPlatformWorkSearchResults(entries, keyword)` 与 `isExactPublicWorkCodeSearch(entries, keyword)`：统一搜索归一化、compact code 匹配和排序。
+- `parsePlatformEntryTimestamp(value)` / `getPlatformWorldTimestamp(entry)`：统一兼容 ISO 与后端 seconds.microsZ 时间戳。
+- `filterTodayPublishedEntries(entries)`：统一“今日游戏”本地自然日筛选。
+- `getPlatformWorldLikeCount(entry)` / `getPlatformWorldPlayCount(entry)` / `getPlatformWorldRemixCount(entry)`、`buildPlatformRankingEntries(entries, tab)` 与 `getPlatformRankingMetricValue(entry, tab)`：统一公开卡片指标读取、排行 Tab 排序与取值。
+- `getPlatformCategoryKindFilter(entry)`、`matchesPlatformCategoryKindFilter(entry, kindFilter)`、`sortPlatformCategoryEntries(entries, sortMode)` 与 `getPlatformCategoryPrimaryMetric(entry)`：统一分类频道的玩法过滤、排序和主指标展示。
+
+`RpgEntryHomeView.tsx` 只消费这些 ViewModel 函数，保留渲染、事件处理和账号状态。公开作品规则的 **Locality** 转移到 ViewModel **Module** 与其测试，页面不再持有这批纯规则。
+
+## 约定
+
+- 公开作品身份 key 与平台入口推荐流保持一致，优先复用 `platformPublicGalleryFlow`。
+- 搜索应同时匹配作品号、`profileId`、`workId`、标题、作者、摘要和副标题。
+- 搜索排序先看标题前缀，再看作品号 compact 前缀，最后按发布时间 / 更新时间倒序。
+- 时间解析必须保留后端 `seconds.microsZ` 兼容。
+
+## 后续深化
+
+下一步可把移动 / 桌面 discover feed 的数据准备继续迁入 ViewModel，但卡片 JSX 与交互状态仍留页面内。
+
+## 验证
+
+- `npm run test -- src/components/rpg-entry/rpgEntryPublicGalleryViewModel.test.ts`
+- `npm run typecheck`
+- `npm run check:encoding`
+- 针对变更文件执行 ESLint
