+## RPG 已发布结果页进入世界不能重复 publish_world
+
+- 现象：RPG 草稿发布成功后，按钮文案已变为“进入世界”，但点击仍请求 `POST /api/runtime/custom-world/agent/sessions/{sessionId}/actions` 且 payload 为 `{"action":"publish_world"}`，后端返回 `publish_world is only available during object_refining, visual_refining, long_tail_review or ready_to_publish`。
+- 原因：按钮文案依据 agent session `stage === 'published'` 切换，但点击处理仍走发布协调路径；如果前端只依赖草稿同步回包判断是否已发布，回包为空或缺少可进入状态时就会继续重复发送 `publish_world`。
+- 处理：进入世界协调器接收当前 agent session stage；当 stage 已为 `published` 时，只调用 `result-view` 回读已发布 profile 并启动运行态，不再调用 `sync_result_profile` 或 `publish_world`。
+- 验证：`npm run test -- src/components/rpg-entry/useRpgCreationEnterWorld.test.tsx`；确认已发布场景下 `syncAgentDraftResultProfile` 与 `executePublishWorld` 均未被调用。

+## RPG 点击启动黑屏先查 profile 归一化和角色选择兜底
+
+- 现象：作品详情点击“启动”后页面切到 RPG runtime，但用户只看到黑屏或空白；DevTools 里可能同时看到旧自动存档 `/api/runtime/save/snapshot` 被主动 cancel。
+- 原因：`/custom-world-library` / `/custom-world-gallery` 详情接口可能返回历史或摘要式 `profile`，缺少 `playableNpcs`、`storyNpcs`、`landmarks`、`attributeSchema` 等运行态字段；前端 client 若直接把该对象传给 runtime，角色选择首屏会在 `buildCustomWorldPlayableCharacters(profile)` 或后续属性解析处抛错。`save/snapshot (canceled)` 通常是切 runtime 或卸载时 `AbortController` 取消旧自动存档，不是黑屏根因。
+- 处理：RPG 入口作品库 client 在所有返回 `CustomWorldLibraryEntry<CustomWorldProfile>` 的接口边界统一调用 `normalizeCustomWorldProfileRecord`，并用 `profileId/worldName/subtitle/summaryText` 补齐旧数据缺字段；角色选择页对角色生成异常或空数组回退默认角色，并保留返回按钮/轻量空态；顶层 runtime 懒加载 fallback 不使用纯 `null`。
+- 验证：`npm run test -- src/services/rpg-entry/rpgEntryLibraryClient.test.ts`、`npm run test -- src/components/rpg-entry/RpgEntryCharacterSelectView.test.tsx`、`npm run typecheck`。

 RPG API 仍沿用历史命名空间：`/api/runtime/custom-world*`、`/api/story/*`、`/api/runtime/chat/*`。这些路由在 `api-server` 入口熔断中统一映射到 `rpg`，只按 `open` 判断是否允许调用；`visible` 只控制创作页入口展示和作品架可见性。
 
-RPG Agent 结果页发布动作的前端契约只保证提交 `{ action: 'publish_world' }`；后端发布时以当前 `custom_world_agent_session.draft_profile_json` 为草稿真相，从 `settingText`、`creatorIntent.rawSettingText`、`creatorIntent.worldHook`、`worldHook`、`anchorContent.worldPromise(.hook)`、`summary`、`name/title` 依次派生正式 `setting_text`，最后才回退 `seed_text`。不要把 `seed_text` 当作唯一设定来源，旧会话可能为空。
+RPG Agent 结果页点击发布或发布并进入世界时，必须先把结果页当前 profile 通过 `sync_result_profile` 保存回 `custom_world_agent_session.draft_profile_json`，再发送发布动作；发布动作前端契约只允许提交 `{ action: 'publish_world' }`，`api-server` 只补作者公开信息，不转发 `profile`、`draftProfile`、`legacyResultProfile` 或 `settingText`。`spacetime-module` 发布时只读取当前 session 的 `draft_profile_json` 作为草稿真相，从 `settingText`、`creatorIntent.rawSettingText`、`creatorIntent.worldHook`、`worldHook`、`anchorContent.worldPromise(.hook)`、`summary`、`name/title` 依次派生正式 `setting_text`，最后才回退 `seed_text`。不要把 `seed_text` 当作唯一设定来源，旧会话可能为空。
 
-`legacyResultProfile` 只作为历史结果页 profile 兼容兜底；`publish_world` 请求缺省或显式为 `null` 时等价于未提供，编译正式 profile 时不得因此报 `custom_world.compile.legacy_result_profile_json 不是合法 JSON object`。真正的数组、字符串、数字等非 object legacy 载荷仍应拒绝。
+Agent session 已进入 `published` 后，结果页按钮只能执行“进入世界”：前端需先通过 `result-view` 回读已发布 profile 并启动运行态，不得再次调用 `sync_result_profile` 或发送 `{ action: 'publish_world' }`。`publish_world` 只允许在 `object_refining`、`visual_refining`、`long_tail_review`、`ready_to_publish` 等发布前阶段触发；否则会被后端阶段门槛拒绝。
+
+`legacyResultProfile` 只作为历史结果页 profile 兼容兜底；编译正式 profile 时，session 草稿内已保存字段优先于 legacy 字段，legacy 只能补缺失字段。`publish_world` 不再接受前端临时传入的 legacy 载荷；历史兼容路径中 legacy 缺省或显式为 `null` 时等价于未提供，不得因此报 `custom_world.compile.legacy_result_profile_json 不是合法 JSON object`。真正的数组、字符串、数字等非 object legacy 载荷仍应拒绝。
 
 RPG 结果页开局 CG 是 `profile.openingCg` 资产槽位：`api-server` 负责 VectorEngine / OSS 副作用并返回故事板和视频引用，前端只把结果写回当前 profile；`sync_result_profile`、作品库保存和 `normalizeCustomWorldProfileRecord` 都必须保留该槽位。若生成成功后画面短暂显示又变回空白，优先检查父层重新同步或 profile 归一化是否把 `openingCg` 丢掉，而不是先怀疑已生成资源本身失效。
 
+RPG 从作品架、广场详情或作品号搜索点击“启动”前，入口 client 必须把后端返回的完整 `profile` 先经过 `normalizeCustomWorldProfileRecord`，并用作品条目的 `profileId/worldName/subtitle/summaryText` 补齐旧数据缺失字段；运行态和详情页不得直接消费未归一化的旧 profile。角色选择页还需要在角色数组异常或为空时回退默认角色，并显示可返回的轻量空态，不能 `return null` 造成黑屏。运行态懒加载 fallback 必须可见，不能用纯 `null` 让用户误判为黑屏。
