@@ -1309,4 +1309,6 @@ DirectProject 使用 `approvalPolicy=never`，避免每次原生调用再经过
 - **Agent 资源检索投影**：`agc_list_registered_assets` 的投影在 `mediaType` 之后固定新增 `category` 与 `tags`，取值直接透出 manifest 已解析的分类（**不在投影层重新按 kind 派生**，否则会覆盖用户显式分类）；不改 manifest 结构、不改对外 OpenAPI 或 SpacetimeDB schema。
 - **素材重命名**：新增 `rename_local_project_asset`（`project/asset_rename.rs`）。语义是**磁盘文件改名 + manifest `localPath` 更新、资产 `id` 不变**（manifest 没有 `name` 字段，显示名来自 `fileName(localPath)`）。校验覆盖新名非空、不含路径分隔符与 `..`、不跨目录、扩展名必须一致、目标不得已存在、原文件必须是真实普通文件；持项目写锁按“读 manifest → 磁盘改名 → 更新 `localPath` → 写 manifest → 推进 revision”执行，**写失败把文件改回原名**，回滚也失败时两个错误都报出并标记 `reconciliation-required`；同名重命名是空操作。已知边界：**不改游戏源码里对旧 `assets/<name>` 的引用**，不做引用扫描与自动替换。
 - **聊天引用与润色**：`ResourceReferenceInput` 新增 `activeVersionId?: string | null` 与 `versions?: GameIterationVersion[]` 两个可选 prop；`@` 面板两个页签（当前版本素材 / 全部画布素材）各自持有独立 `{query, filter, selectedResourceIds}`。版本解析口径 `resolveActiveIterationVersion` / `currentIterationVersionAssets`：传 `null` 回退 manifest 最新的版本，悬空绑定自然丢弃，空版本或空绑定显示空态而不报错。新增 `polish_local_project_prompt(prompt, context)`（提示词 `src-tauri/prompts/local-project-prompt-polish.md`），复用与 `suggest_automatic_project_name` 同一条短文本通道：`codex_app_server` 模式走 home direct codex，其余走 `LlmClient` 单轮请求；入参有界（4 000 / 1 000 字符）、输出 2 048 token 有界、空回复一律判失败以保留原文。**计费不自建**：泥点扣费仍在 `server-rs` 的 `/api/llm/chat/completions` 与 `/api/llm/responses` 路由（`prepare_llm_router_billing` / `settle_llm_router_usage`），本次 server-rs 零改动。发送前提醒是 portal 独立弹窗，判据为“提醒未关闭 + 本轮未确认 + 纯文本 trim 后 ≥ 40 字符 + 不以 `/` 开头”，“不再提醒”偏好存本机 `localStorage`，不进 manifest 与后端。
+- **画布生成入口（C3 收口）**：资源画布新增「生成素材」入口，点击打开独立浮层面板（`ResourceCanvasGenerationPanelView` + `ThemedModal`，与资源面板同一套宿主 chrome，不在任何现有面板下面追加内容）。面板只提供本地契约真正支持无源生成的三类：视频 / 音效 / 背景音乐；提交走 `derive_local_project_resource`，`generationMode='create'`、`sourceResourceId='create:<operationId>'`，`sourceAssetId / sourcePath / sourceSubtype / producerTaskId / sourceVersionId` 全为 `null`，失败重试复用同一对 `operationId / idempotencyKey`；产出后经 `pendingResourceFocusRef` 定位并选中新素材卡。入口渲染门禁是 `isResourceCanvasGenerationAvailable`（客户端 invoke 桥存在 + `projectPath` 与 `manifest.projectId` 就绪），不满足时整块不渲染。**已知边界（本轮未完成项）**：`project/resource_editor.rs` 的 create 分支只放行 video / sound-effect / background-music，图片（`image-reference`）会被返回「当前资源类型不支持无源生成」；图片臂的远端请求固定走 `/api/editor/images/edits` 并要求正式源引用，入参结构体里也没有 model / aspectRatio / imageSize。因此本轮**不提供图片无源生成入口**，也**不把图片专属的模型 / 比例 / 尺寸 / 像素艺术 / 泥点价复用到这三类上**（那会渲染出不真实的图片价格）。后续要做图片生成入口，必须先扩展该命令的入参与该分支的端点路由。
+- **C3 生成入口验证**：AGC 前端全量 1100 passed / 4 skipped / 0 failed（该基线上 1092 + 本次新增 8 条）；共享美术画布组件 1385 passed；`npm run ai-game-creator-shell:typecheck`、`npm run check:encoding`、`git diff --check` 全绿；本轮 Rust 零改动。
 - **验证**：AGC 前端全量 1075 passed / 4 skipped / 0 failed；共享美术画布组件 1372 passed；`cargo check --all-targets` 通过；定向 Rust 用例 `asset_delete` 7、`manifest::` 30、`assets::tests` 22、`asset_rename` 9、`local_project_prompt_polish` 4、`bridge_registered_resource` / `bridge_art_resource` 3 全绿；`npm run check:encoding` 与 `git diff --check` 干净。
