 ## 2026-06-03 平台入口公开作品详情 Strategy 收口
 
 - 背景：平台壳层直接判断公开作品详情入口的玩法类型、是否需要补读完整详情，以及自有作品按钮显示“编辑”还是“改造”，导致统一作品详情的纯决策散落在巨型 Implementation 内。
-- 决策：新增 `src/components/platform-entry/platformPublicWorkDetailFlow.ts`，以 `getPlatformPublicWorkDetailKind`、`resolvePlatformPublicWorkDetailOpenStrategy` 和 `resolvePlatformPublicWorkActionMode` 收口公开作品详情 Strategy。`PlatformEntryFlowShellImpl.tsx` 只按 Strategy 调用现有详情读取 / 直接展示 Adapter；启动、点赞、remix 和编辑副作用暂不抽走。
+- 决策：新增 `src/components/platform-entry/platformPublicWorkDetailFlow.ts`，以 `getPlatformPublicWorkDetailKind`、`resolvePlatformPublicWorkDetailOpenStrategy`、`resolvePlatformPublicWorkActionMode`、`resolvePlatformPublicWorkDetailOpenDecision` 和 `resolveActivePlatformPublicWorkAuthorEntry` 收口公开作品详情 Strategy。`PlatformEntryFlowShellImpl.tsx` 只按 Strategy 调用现有详情读取 / 直接展示 Adapter，并保留作者请求竞态控制；启动、点赞、remix 和编辑副作用暂不抽走。
 - 影响范围：统一作品详情入口、公开详情打开策略、自有公开作品编辑 / 改造动作模式，以及后续新增玩法公开详情接入。
 - 验证方式：`npm run test -- src/components/platform-entry/platformPublicWorkDetailFlow.test.ts`、公开详情壳层交互回归、`npm run typecheck`、`npm run check:encoding`。

 - 本次不抽 `startSelectedPublicWork`、`likePublicWork`、`remixPublicWork`、`editOwnedPublicWork`。这些函数牵涉运行态启动、计数写入、草稿恢复、作品架缓存和多路错误 setter；若直接搬进一个 Hook，会形成浅 Interface。

 - 大鱼吃小鱼、抓大鹅、方洞挑战、汪汪声浪、宝贝识物和其它可直接展示的公开 entry 返回 `use-entry` strategy。
 - RPG 返回 `load-rpg-detail` strategy，由壳层 Adapter 继续调用 RPG 详情读取流程。
 - `resolvePlatformPublicWorkActionMode` 只比较 `entry.ownerUserId` 与当前 viewer user id；当前用户拥有该公开作品时返回 `edit`，否则返回 `remix`。
+- `resolvePlatformPublicWorkDetailOpenDecision` 只表达直接展示公开详情的打开 / 阻断结果、错误文案、目标 stage 与可写入历史的路径；真正执行 setter、push history 的副作用仍由壳层 Adapter 执行。
+- `resolveActivePlatformPublicWorkAuthorEntry` 只在 `work-detail` 阶段选择统一公开详情 entry，在 RPG `detail` 阶段只选择非 draft 的 RPG 详情 entry；作者请求、竞态 request key 和缓存仍留壳层。
