+
+## 1. 边界
+
+本 checklist 只推进 local-first 普通 Markdown 的真实 agent 文件编辑闭环，不碰 LightRAG、Knowledge RAG、OCR、evidence index 或 OnlyOffice recipe 扩展。当前另一个 agent 正在修改 LightRAG 相关文件，本轮不得编辑：
+
+- `rust/crates/mnote-web/src/routes/knowledge_rag.rs`
+- `rust/crates/mnote-web/src/hermes_tools/knowledge_rag.rs`
+- `design/07-ai/done/7-50-lightrag-knowledge-rag-provider-v1.md`
+- `scripts/task529*` 到 `scripts/task534*`
+
+## 2. 当前代码证据
+
+已有基础能力：
+
+- Page AI target 会生成 `mnote.agent_target_package.v1`，并给目标写入 `allowedFiles`、`policy.conflictPolicy=fail_on_dirty_or_stale`。
+- 发送 run 前会通过 `/api/documents/buffer-state` 检查 dirty / external modified 状态；阻塞时抛 `page_ai_target_buffer_not_writable`。
+- 后端会生成 `mnote.agent_run_envelope.v1`，其中 `resultPolicy.changedFiles=required`、`refresh=watcher_or_explicit_resync`。
+- `scripts/reasonix-acp-wrapper.mjs` 会把 `agentRunEnvelope` 写进模型可见 prompt，要求 agent 使用自身文件工具编辑真实文件。
+- `local_agent_audit_finalize_run` 会基于前后快照生成 `changedFiles` 和 `mnote.agent_run_receipt.v1`。
+- 前端 `pageAiDispatchReceiptRefresh(...)` 会把 receipt 转成 `tree:local-folder-watch-batch` 和 `mnote:page-ai-tool-write-completed`。
+
+当前缺口：
+
+- 没有一条真实浏览器 smoke 证明 agent 原生 patch 修改当前 `.md` 后，前台 tiptap 在 clean buffer 下可见更新。
+- dirty buffer 的阻塞虽然已有函数，但缺少端到端 smoke 证明不会启动可写 run 或不会静默覆盖。
+- readonly 写入目前仍偏后置审计：`read_only_write_rejected` 可以记录结果，但还需要前置拒绝或 tool/ACP 层明确失败。
+- 审计快照在 folder context 下会退回 full snapshot；产品化前需要限制为 `allowedFiles` / changedFiles 优先，并对超限降级有可见记录。
+
+## 3. 非目标
+
+- 不新增 MNote 普通 Markdown 写入工具。
+- 不把 `mnote.doc.markdown_edit` 恢复为 local-first fallback。
+- 不实现 streaming apply、review session、GhostTextOverlay。
+- 不要求真实外部大模型；smoke 可以用受控 ACP stub / Hermes test runtime 模拟 agent 原生文件 patch，但必须真实写磁盘文件。
+- 不把 LightRAG retrieval、evidence citation 或 OCR sidecar 混入本闭环。
+
+## 4. Phase A：clean buffer 真实写入回收 smoke
+
+目标：证明 agent 原生文件编辑 -> watcher / receipt -> 当前前台 tiptap 可见更新。
+
+Checklist：
+
+- [x] 新增 `scripts/task535-page-ai-local-agent-clean-edit-smoke.js`。
+- [x] smoke 创建临时 local-folder workspace 和目标 `AgentClean.md`。
+- [x] 浏览器打开该 Markdown，确认 `mnote-leptos-tiptap-island-editor-root` ready。
+- [x] 通过 Page AI 发起本地 agent run，run payload 必须包含 `targetPackage.currentFile.relativePath`、`allowedFiles`。
+- [x] agent stub / ACP test runtime 只能在 `allowedFiles` 指向的真实 `.md` 上做最小 patch。
+- [x] run completed 后必须返回或触发 `agentRunReceipt.changedFiles`，路径为目标 `.md`。
+- [x] 前端必须触发 `tree:local-folder-watch-batch`，并对当前文档触发 `mnote:page-ai-tool-write-completed`。
+- [x] tiptap 可见正文更新为 agent 写入后的内容，不需要手动 reload。
+- [x] 网络断言本路径不调用 `/api/documents/save`。
+- [x] 工具事件断言本路径不调用 `mnote.doc.markdown_edit`。
+
+验收：
+
+- [x] smoke 输出 `tmp/task535-page-ai-local-agent-clean-edit-smoke/result.json`，包含 run payload、changedFiles、current refresh、最终 editor text。
+- [x] `result.json` 中 `ok=true`，`usedDocumentsSave=false`，`usedMarkdownEdit=false`。
+
+## 5. Phase B：dirty buffer 不静默覆盖 smoke
+
+目标：证明用户本地未保存时，agent 写入不会绕过 buffer 冲突模型。
+
+Checklist：
+
+- [x] 新增 `scripts/task536-page-ai-local-agent-dirty-guard-smoke.js`。
+- [x] 打开目标 Markdown 后在 tiptap 中输入未保存内容，制造 BufferStore dirty 状态。
+- [x] Page AI target chip / run 前检查能读到 dirty 状态。
+- [x] 点击发送可写 run 时，应出现明确阻塞或确认流程；当前最低验收是阻塞并返回 `page_ai_target_buffer_not_writable`。
+- [x] smoke 断言没有启动可写 ACP run。
+- [x] smoke 断言磁盘 `.md` 没有被 agent stub 修改。
+- [x] smoke 断言 editor 中未保存内容仍可见。
+
+验收：
+
+- [x] smoke 输出 `tmp/task536-page-ai-local-agent-dirty-guard-smoke/result.json`。
+- [x] `result.json` 中 `ok=true`，`blockedBeforeRun=true`，`diskChanged=false`，`editorDirtyTextStillVisible=true`。
+
+## 6. Phase C：readonly 前置拒绝 smoke
+
+目标：证明 readonly target 不靠事后审计才发现写入失败。
+
+Checklist：
+
+- [x] 新增 `scripts/task537-page-ai-local-agent-readonly-write-guard-smoke.js`。
+- [x] 构造只读授权或只读 targetPackage：`permission=read`，`allowedFiles` 可读但不可写。
+- [x] 发起“请修改当前文件”的 Page AI run。
+- [x] 前端或后端应在启动可写 ACP run 前拒绝，错误码稳定，例如 `page_ai_target_readonly` 或 `local_agent_write_not_allowed`。
+- [x] 若当前实现只能后置审计，应先把 smoke 写成 RED，记录实际行为，不伪造通过。
+- [x] smoke 断言磁盘文件未变化。
+- [x] smoke 断言 audit 中没有把 readonly 写入说成成功；若出现 `read_only_write_rejected`，必须在 UI 可见错误里体现。
+
+验收：
+
+- [x] smoke 输出 `tmp/task537-page-ai-local-agent-readonly-write-guard-smoke/result.json`。
+- [x] `result.json` 中 `ok=true` 仅在前置拒绝落地后允许；当前若为 RED，应输出 `ok=false` 和真实行为证据。
+
+## 7. Phase D：审计快照范围收口
+
+目标：避免 local agent audit 因 folder context 退回扫全 root，影响大 workspace 和 run 返回速度。
+
+Checklist：
+
+- [x] 后端 `local_agent_audit_relative_paths_from_payload(...)` 优先消费 `agentRunEnvelope.allowedFiles` / `targetPackage.allowedFiles`。
+- [x] folder context 不再直接强制 full snapshot；除非用户明确选择 folder-wide edit 且有上限。
+- [x] 增加审计上限：文件数、总字节数、耗时；超限时进入 `auditScope=truncated`，并在 receipt 中可见。
+- [x] 单测覆盖 allowedFiles 优先、folder context 不扫全 root、超限截断。
+
+验收：
+
+- [x] `cargo test -p mnote-web local_agent_audit -- --test-threads=1` 或等价 targeted tests 通过。
+- [ ] clean smoke 中 audit snapshot 只包含目标文件及必要 changed file。
+
+## 8. Phase E：文档与 manifest 退役口径
+
+目标：锁死 local-first 普通 Markdown 不走旧 MNote 写入工具。
+
+Checklist：
+
+- [x] Page AI / Hermes guidance 对 local-folder 普通 Markdown 明确优先 agent 原生 patch/diff。
+- [x] `mnote.doc.markdown_edit` 在 manifest 中只标注为 online/cloud/compat 历史工具或结构校验辅助。
+- [x] `reasonix-acp-wrapper.mjs` selftest 断言 prompt 包含“不使用 MNote doc/page write tools for ordinary local Markdown edits”。
+- [x] smoke 断言 local-first agent edit 不调用 `/api/documents/save`、`mnote.doc.markdown_edit`、`mnote.page.save`。
+
+验收：
+
+- [x] `7-18-local-first-agent-file-editing-control-plane-v1.md` Phase B/C 可勾选。
+- [ ] 本 checklist 可移动到 `design/07-ai/done/`，父设计 `7-18` 仅剩跨 workspace / 多 target 的产品确认项。
+
+## 9. 推荐执行顺序
+
+1. 先写 `task535` clean smoke，允许 RED，固定真实 run payload / receipt / 前台刷新证据。
+2. 再写 `task536` dirty guard smoke，优先验证当前已有 dirty blocker。
+3. 再写 `task537` readonly guard smoke，若当前只能后置审计则保持 RED。
+4. 最后做审计快照范围收口和 manifest/guidance 口径收紧。
+
+## 10. 归档条件
+
+- clean buffer smoke 真实通过。
+- dirty buffer smoke 证明不会静默覆盖。
+- readonly write smoke 证明前置拒绝或 UI 明确失败。
+- local-first 普通 Markdown agent edit 不调用旧 MNote 写入工具。
+- LightRAG 相关 diff 不在本 checklist 中被修改或作为验收前置。
