+## 代码边界
+
+- 前端：`features/project-workspace/ResourceReferenceInput.tsx`、`ResourceReferenceNode.tsx`、`resourceReferences.ts`、生成绑定及聊天入口透传。
+- Rust：`agent/direct_codex_user_item/model.rs`、`validation.rs`、`wire.rs`、`codex_app_server/mod.rs` 与对应测试。
+- 文档：父规范与本里程碑/实施计划。
+
+## 小切片顺序
+
+1. 先扩展前端 Skill catalog/节点/草稿 content，保持素材行为不变并补前端测试。
+2. 扩展 canonical Rust part 与 ts-rs 绑定，补序列化和失败校验测试。
+3. 接通 Codex wire `type: skill` 转换和受控路径解析，补历史/重放测试。
+4. 完成入口透传、定向验证和文档证据；每个切片单独中文提交。
+
+## 验证与回滚
+
+- `npm --prefix apps/ai-game-creator-shell run typecheck`
+- 相关 Vitest 与 `cargo test --manifest-path apps/ai-game-creator-shell/src-tauri/Cargo.toml direct_codex`
+- `npm run check:encoding`、`npm run check:doc-index`、`git diff --check`
+- 每个切片只改计划列出的文件；若 Codex wire 协议或 Skill catalog 来源不确定，停在该切片并先更新规范。

+| 字段 | 值 |
+| --- | --- |
+| Milestone | `docs/project-memory/plans/【里程碑】DirectProject用户ResponseItem输入-2026-09-15.md` |
+| Status | in-progress |
+| Owner | Codex |
+
+## 修改边界
+
+- 允许修改：AGC 壳 Rust agent 输入合同、DirectProject 历史适配、前端聊天引用模型、ts-rs 生成配置、当前聊天素材文档。
+- 明确不修改：assistant 返回协议、工具 activity、附件/图片协议、SpacetimeDB、HTTP API。
+
+## 实现顺序
+
+1. 提取深模块：Rust canonical user item 的定义、校验和 Codex wire 转换。
+2. 生成并接入 ts-rs 类型，排除生成文件 lint/style。
+3. 将前端 Lexical 草稿从 `text + references[]` 改为 inline content parts。
+4. 修改 Tauri command 与 DirectProject turn：校验通过后持久化 canonical item，再发送转换后的 Codex 输入。
+5. 删除本链路对 legacy conversation 行的读取 fallback，保留标准 `response_item`。
+6. 补齐定向测试与文档验证；每个独立切片形成小提交。
+
+## 验证命令
+
+1. `cargo test --manifest-path apps/ai-game-creator-shell/src-tauri/Cargo.toml direct_codex`
+2. 相关前端 Vitest 与类型检查。
+3. `npm run check:encoding`
+4. `npm run check:doc-index`
+5. `git diff --check`
+
+## 风险与回滚点
+
+- ts-rs 生成路径或 workspace lint 配置不一致：先固定生成入口，再接入业务。
+- 历史中 canonical item 含 AGC part 时，thread replay 必须经过同一 wire converter；转换失败不得启动 turn。
+- 共享工作树存在用户 `.env` 修改，禁止覆盖或提交。
+- 每个切片保持独立提交，出现协议问题时按提交粒度回滚。
