+## 2026-06-07 创作入口泥点消耗改由统一契约驱动
+
+- 背景：创作入口玩法卡封面右下角长期固定显示 `10-20泥点数`，无法在后台按玩法调整，也容易和真实钱包余额或活动奖池混淆。
+- 决策：`creationTypes[].unifiedCreationSpec.mudPointCost` 作为入口卡泥点消耗数量字段，旧契约缺失时后端和前端都兜底为 `10`；入口卡由前端格式化为 `X泥点数` 展示，后端和后台不保存单位文案。该字段只表达入口卡展示数量，不替代各玩法提交、生成或发布链路中的真实扣费校验。
+- 决策补充：后台创作入口开关页不再直接暴露统一创作契约 JSON textarea；页面按契约结构展示为卡片和字段列表，点击“修改契约”后通过弹窗表单编辑 `title`、`mudPointCost` 和 fields，再组装回统一契约 payload 保存。`workspaceStage`、`generationStage` 和 `resultStage` 属于内部阶段标识，后台不展示也不允许编辑；保存时沿用已有契约值，新增契约时按 `playId` 的固定阶段映射自动带出。
+- 影响范围：`shared-contracts` 的 `UnifiedCreationSpecResponse`、`/api/creation-entry/config` 响应、前端入口卡派生、后台入口开关页、玩法链路文档和创作入口回归测试。
+- 验证方式：后台修改 `mudPointCost` 后保存，`GET /api/creation-entry/config` 返回同名数字字段；底部加号创作入口卡显示前端格式化后的泥点消耗；关闭态卡片仍只显示 `暂未开放`。

+## 2026-06-06 统一创作页表头按契约 title 原样显示
+
+- 背景：统一创作页长期使用固定表头 `想做个什么玩法？`，导致跳一跳等玩法希望按自身语义展示标题时只能改前端或默认契约。
+- 决策：`creationTypes[].unifiedCreationSpec.title` 继续作为统一创作页表头传输字段，但读取和保存时都按契约内容原样显示和持久化，不再用入口 `title` 自动覆盖。默认 spec 可以给出玩法中文名；旧库中已经持久化为 `想做个什么玩法？` 的契约也保持原样，若需要改表头应在后台契约结构卡片中点击修改并编辑 `title` 字段。
+- 影响范围：`shared-contracts` 默认 spec、`module-runtime` 入口配置响应、`spacetime-module` 后台保存校验、后台入口开关页摘要和前端 fallback spec。
+- 验证方式：`GET /api/creation-entry/config` 中各玩法 `unifiedCreationSpec.title` 等于已保存契约内容；后台只修改入口名称时不应隐式改写已保存的统一创作页表头。

 - 现象：创作 Tab 两列玩法卡上图能看到，但标题、描述或预计消耗泥点在白底信息区里看不见，或只剩泥点小图标。
 - 原因：旧 `platform-creation-reference-card` 是给暗图蒙版卡用的全局样式，会把卡片及全部子元素强制成白色文字；参考图要求的是“上图 + 下方白底信息区”，继续复用旧类会让白底上的文字消失。
 - 处理：创作 Tab 首屏模板卡使用独立 `creation-template-card`、`creation-template-card__body`、`creation-template-card__title`、`creation-template-card__subtitle` 和 `creation-template-card__cost` 结构，不挂 `platform-creation-reference-card`；旧弹层如果仍是暗图蒙版卡，可以继续保留旧类。
-- 验证：浏览器创作 Tab 中每张卡都应显示标题、描述和“预计消耗 10-20 泥点”；`npm test -- src/components/custom-world-home/CustomWorldCreationHub.test.tsx -t "creation start card renders reference-aligned banner and template metadata"` 应通过。
