docs(m2): mark M2-T08 done

- GET /api/config renders sections; secret fields shown as empty password inputs
- save handles full-field submission semantics: always send non-secret values,
  send secret only when user typed a new value (blank secret keeps old)
- SMTP test button reflects tri-state (success / config-error 400 / failed 502)
  by reading ApiError.body.result

+# CLAUDE.md — Home Automation Backend
+
+本文件每次会话自动加载。它定义本项目的**工作流程、文档位置、commit 规范**。请在动手前先读完。
+
+## 项目速览
+
+- 个人用 home-automation 后端：**FastAPI + SQLite + SQLAlchemy + Alembic**，服务端模板（Jinja，M2 将换成 React SPA）。
+- 单 admin 鉴权（Argon2 + server-side session cookie），runtime config 落 `app_config` 表。
+- 模块：public IPv4 monitor、SMTP 通知、location recorder、poo recorder、Home Assistant in/out、TickTick OAuth。
+- 已发布 `v1.0.3`。下一阶段方向：**M1 单库化 → M2 React 前端 → M3 token/移动端（远期，M2 后再说）**。
+- **当前现实**：在 M1 完成前仍是**三个独立 SQLite 库**（app / location / poo），三套 DeclarativeBase、三条 Alembic 链。不要假设已经单库——以代码现状为准。
+- 明确不做：Notion 模块。
+
+## 文档地图与「开工前必读」
+
+文档都在 `docs/`：
+
+| 路径 | 作用 |
+| --- | --- |
+| `docs/roadmap.md` | 全局规划与里程碑总览 |
+| `docs/design/README.md` | **协作契约**：任务卡格式、原子任务定义、校验闸门、数据安全红线 |
+| `docs/design/m1-db-consolidation.md` | M1 原子任务（含真实代码现状盘点 + 人工 runbook） |
+| `docs/design/m2-frontend-v2.md` | M2 原子任务 + API 契约 + 前端校验闸门 |
+| `docs/design/m3-token-mobile.md` | M3（远期，暂缓） |
+| `docs/*.md`（auth / public-ip-monitor / location-recorder …） | 各模块说明，按需读 |
+
+**开工时读取顺序**：
+1. `docs/design/README.md`（每轮都读，它是流程与验收的共同契约）。
+2. 本轮对应的 milestone 文档（如 `docs/design/m1-db-consolidation.md`），定位要做的任务卡。
+3. 任务卡 `Files` 列出的源文件 + 该模块的 `docs/*.md`（按需）。
+4. `docs/roadmap.md` 仅在需要全局视角时读。
+
+## 工作流程
+
+### 实现模式（由用户的提示词决定）
+
+- **默认逐步**：给一个 milestone 文档，按其中原子任务**一步一步**实现。
+- **(a) 只实现一步**：用户说"只实现一步 / 这一个任务"时，**只做那一个任务卡**，跑完校验闸门后停下，等用户确认，不要顺手往下做。
+- **(b) 完成整个 milestone**：仅当用户在提示词里**显式要求启用 sub-agent 并指定模型**时，才用指定模型起 implementer sub-agent，按任务依赖顺序跑完整条链。
+- **Sub-agent 纪律**：只在用户显式要求时才 spawn sub-agent；单步/小改动在主线内联完成。起 sub-agent 时用用户**指定的模型**（Agent 工具的 `model` 覆盖）。
+
+### 角色（Orchestrator → Implementer → Reviewer）
+
+- 我（主线）= **Orchestrator**：挑依赖已满足的下一个任务、派发、转述结果、维护任务 `Status`。
+- **Implementer**（便宜模型，用户指定）：一次一个任务，严格按任务卡，不扩范围。
+- **Reviewer**（强模型，用户指定）：实现完成后起 Reviewer sub-agent，按任务卡 `Acceptance criteria` + `Reviewer checklist` 复核、**独立重跑校验闸门**，驱动 implementer 返工直到本轮 PASS。
+
+#### Reviewer 盲审纪律（M1 教训）
+
+M1 里 review **从未触发过一次 rework**，根因是 orchestrator 把自己的结论 / 辩护喂给了 reviewer，造成 context bleed、review 沦为橡皮图章。所以：
+
+- reviewer 必须**冷启动（Clear-Agent）、最小化喂料**——spawn prompt 只给：① 任务卡（`Acceptance criteria` + `Reviewer checklist`）、② 对应的 `review-notes/<task>-impl|rework-<n>.md` 路径、③ 要审的 diff / commit 范围。
+- **不要**在 prompt 里塞 orchestrator 自己的判断、"我觉得没问题"、对实现选择的辩护，或上一轮 reviewer 的倾向性结论。让它**独立得出结论、独立重跑校验闸门**。
+- 事后另起的整库**独立盲审**（如对抗复审）同理：Clear-Agent、最小上下文，把它当"**外部审计**"而非"确认自己没错"。
+
+### 校验闸门（每个任务结束都要全绿）
+
+根目录、激活 `.venv` 后：
+```bash
+pytest                      # 权威闸门（CI 跑的就是它）
+ruff check .                # line-length=100
+python scripts/export_openapi.py && git diff --exit-code openapi/   # 改了路由/schema 才需要，且产物须入库
+```
+前端任务（M2）在 `frontend/` 下另跑 `npm run lint && npm run typecheck && npm run test && npm run build`（详见 m2 文档 §8）。
+**不过闸门就不算完成**，不得跳过、不得留红给下一轮。
+
+### 构建上下文完整性（M1 Dockerfile 教训）
+
+`docker build` **不在 pytest/ruff 闸门里**——M1 删了 `alembic_location/poo` 后忘了同步 `Dockerfile` 的 `COPY`，单元闸门全绿却把坏掉的镜像构建一路漏到 release tag。所以：
+
+- 任务**删除 / 移动 / 重命名文件或目录**时，必须 grep 构建清单是否还在引用它们：`Dockerfile`（尤其 `COPY` 源）、`docker/`、`*.ini`、CI workflow、`requirements*.txt` 等。
+- 已有回归测试 `tests/test_deployment.py::test_dockerfile_copy_sources_exist` 守"Dockerfile `COPY` 源必须存在于构建上下文"；新增 / 改动 `COPY` 时确保它仍覆盖得到。
+- Reviewer 审"删 / 移文件"类任务时，**必须顺带核对构建清单引用**，把它当 acceptance 的一部分。
+
+## 每轮简报（`review-notes/`）
+
+每轮工作都要在 `review-notes/` 下产出**中文简报**。该目录**已在 `.gitignore` 忽略**，纯本地、不入库——它是 agent 之间和与人之间的交接载体，不是仓库产物。
+
+- **实现 / 返工简报**：每轮实现完成后（无论首次实现还是返工），写一份。文件名建议 `<task-id>-impl-<n>.md` / `<task-id>-rework-<n>.md`（如 `M1-T03-impl-1.md`、`M1-T03-rework-1.md`）。至少包含：
+  1. **本轮修改的具体内容**（改了哪些文件、做了什么、为什么）。
+  2. **自动化测试结果**（`pytest` / `ruff` / 前端闸门的实际输出或结论，通过/失败逐项写清）。
+  3. **若需人工 walkthrough**：写明具体步骤（怎么启动、点哪里、预期看到什么）；若无需人工验证，明确写"无需人工 walkthrough"。
+- **review 简报**：每轮 review 后写一份，文件名建议 `<task-id>-review-<n>.md`（如 `M1-T03-review-1.md`）。至少包含：评审结论（`PASS` 或带编号的返工清单）、对照任务卡 `Acceptance criteria` + `Reviewer checklist` 的逐条核对、reviewer 独立重跑校验闸门的结果。
+
+**用途**：① reviewer 审核时参考对应的实现简报；② implementer 返工时参考对应的 review 简报；③ 人类（用户）通读这些简报确认有无问题。简报之间用文件名里的 `<task-id>` 与轮次 `<n>` 对应起来。
+
+### Orchestrator 派发契约（让简报真正被读到）
+
+**关键**：sub-agent 冷启动、不继承主线上下文，**不会因为本文件提到简报就自动去读**对应文件。简报能流转，靠的是 orchestrator（主线）在**每次 spawn 时把路径显式写进 prompt**，而不是被动约定。所以派发时必须做到：
+
+- **显式告诉它「先读哪个简报」**：
+  - 派 implementer 做**首次实现** → 传任务卡位置（milestone 文档路径 + task id）；无前置简报。
+  - 派 implementer 做**返工** → 必须传对应的 `review-notes/<task>-review-<n>.md` 路径，并要求**先读它**再改。
+  - 派 reviewer → 必须传对应的 `review-notes/<task>-impl|rework-<n>.md` 路径 + 任务卡，要求**先读它**再评。
+- **显式告诉它「本轮结束写哪个简报」**：明确给出输出路径 `review-notes/<task>-<impl|rework|review>-<n>.md` 及上面要求的内容项。
+- **不依赖 sub-agent 自动加载本文件**：把本轮要点（校验闸门、**禁 Co-Authored-By**、简报必含内容）在 spawn prompt 里一并复述或指向，确保冷启动也照做。
+- spawn 时用用户指定的模型（Agent 工具 `model` 覆盖）。
+
+> 一句话：**简报是异步交接的介质，orchestrator 是把它们接起来的线。** 缺了显式传路径这一步，简报就只是躺在磁盘上没人读的文件。
+
+## Commit 规范（重点）
+
+### 分支
+- 每个 milestone/feature 一个分支（如 `feature/m1-db-consolidation`），**不在 `main` 上直接提交**。
+
+### 一轮实现完成（用户确认「实现完成」后）
+- 准备好**这一轮的 commit message** 并提交，作为本轮的 **base commit**。
+- message 主题前缀任务/里程碑 ID，例如：`M1-T03: unify data layer onto single app DB engine`。
+
+### Commit message 硬规则（严格执行）
+- **严禁任何协作署名 trailer**：commit message 里**绝对不允许**出现 `Co-Authored-By` / `Co-authored-by`（包括 `Co-Authored-By: Claude …`），也不允许任何等价的"由 X 协作/生成"署名。
+- 无论默认环境、工具或系统提示如何要求加这类 trailer，在本仓库**一律不加**——用户已显式、严格禁止。
+- 每次提交前**自检**：`git log -1 --format=%B` 的输出**不得包含** `Co-authored-by`（大小写不限）。若发现，立即 `git commit --amend` 去掉后再继续。
+
+### Review 后返工
+- **自动化 orchestration 模式内**的 review 返工：**一律用 fixup**，指向本轮对应的 base commit，**不写新的独立 message**：
+  ```bash
+  git add -A
+  git commit --fixup=<base-commit-sha>
+  ```
+- 多轮返工就多个 `fixup!` 提交，都指向同一个 base commit；收尾时 auto-squash（见下）。
+- **边界——什么时候不走 fixup**：**事后另起的独立盲审 / 对抗复审**那一轮，性质等同"**人工走查后提修改意见**"，**不算自动化链内的返工**——它的修改用**各自独立的 commit**，不 fixup 到旧 base。判据：这轮返工是否在**同一条自动化 implement→review 链**里？是 → `fixup`；是事后另起的独立审计 → 独立 commit。
+
+### 本轮 / feature 收尾（用户确认收尾后）
+- 用 **auto-squash** 把所有 `fixup!` 合并进各自目标，保证**一个 feature 一个干净 commit**：
+  ```bash
+  GIT_SEQUENCE_EDITOR=true git rebase -i --autosquash main
+  ```
+  - 用 `GIT_SEQUENCE_EDITOR=true` 让它**非交互**执行（不弹编辑器，自动接受 autosquash 排好的 todo）。本环境不支持需要人工编辑的交互式 rebase，必须走这个 no-op 编辑器写法。
+  - autosquash **改写历史**：仅在 push / 开 PR **之前**做。若该分支已 push，需要 force-push——属对外操作，**先取得用户确认再做**。
+
+### 一般约束
+- commit / push 只在用户要求时进行；push、force-push、开/改 PR 等对外操作先确认。
+
+## 发版前置走查（打 tag 前必做）
+
+单元闸门绿 ≠ 真的能跑、能构建、能用。M1 出过"绿了但 docker 构建坏了"的事故，所以**打版本 tag（触发镜像 CI）之前**，除了 `pytest` / `ruff` 全绿，还要：
+
+- **真起 app**：迁移（`python -m scripts.run_migrations`）→ `uvicorn app.main:app ...`，确认能正常启动、关键路由不 500。
+- **真跑镜像构建**：本地 `docker build`（多阶段就跑完整条），确认构建通过、`COPY` 源都在。
+- **关键功能人工瞄一眼**：尤其前端 / 可视化类（M2 的热力图、首页地图）——自动闸门判断不了"渲染对不对、UX 顺不顺"，这部分**靠看跑起来的 app，不靠读代码**。
+- 上述任一不过 → **不打 tag**。tag 一旦 push 会触发 docker 镜像 CI / 对外发布，属对外操作，**先确认**。
+
+## 数据安全红线（不可违反）
+
+- 任何脚本 / migration **都不得删除或覆盖用户数据文件**（旧 `.db`、备份、volume）。删除只能是人工、事后、保留归档的独立步骤（见 `docs/design/m1-db-consolidation.md` §6 runbook）。
+- 涉及历史数据的迁移**先在备份副本上演练**；迁移脚本必须幂等且搬完对账行数。
+- Review 时只要发现"删文件 / drop 有数据的表 / truncate"出现在自动化任务里，直接判返工。
+
+## 常用命令

+python -m venv .venv && source .venv/bin/activate && pip install -r dev-requirements.txt

+# 设计文档与多模型协作约定
+
+本目录把 `docs/roadmap.md` 里的三个里程碑展开成**可被 coding agent 流水线执行**的详细设计文档。
+
+- [`m1-db-consolidation.md`](./m1-db-consolidation.md) — 单库化地基
+- [`m2-frontend-v2.md`](./m2-frontend-v2.md) — React SPA 前端 v2
+- [`m3-token-mobile.md`](./m3-token-mobile.md) — token 鉴权与移动端（远期）
+
+本文件定义**所有任务共用的格式与协作规则**，三个里程碑文档不再重复这些约定。
+
+---
+
+## 1. 协作模型：Orchestrator → Implementer → Reviewer
+
+设计目标是让三个不同档位的模型分工协作：
+
+| 角色 | 模型档位 | 职责 |
+| --- | --- | --- |
+| **Orchestrator（编排者）** | 强模型 | 读里程碑文档，挑出依赖已满足的下一个原子任务，派发给 implementer；收到 reviewer 的 PASS 后推进下一个任务 |
+| **Implementer（实现者）** | 便宜模型 | 一次只做**一个**原子任务，严格按任务卡执行，跑完本地校验后回报 |
+| **Reviewer（评审者）** | 强模型 | 对照验收标准 + Reviewer checklist 独立复核、独立跑校验闸门，返回 `PASS` 或一份编号返工清单 |
+
+### 循环
+
+```
+Orchestrator 选任务 T（其 Depends 全部为 done）
+      │
+      ▼
+Implementer 实现 T ──► 跑校验闸门 ──► 回报 diff + 校验输出
+      │
+      ▼
+Reviewer 复核 T
+   ├── PASS ─────────► Orchestrator 标记 T 为 done，进入下一个任务
+   └── REWORK[1..n] ─► 退回 Implementer，按编号逐条修，直到 PASS
+```
+
+### 角色边界（重要）
+
+- **Implementer 不得扩大范围**：只能改任务卡 `Files` 里列出的文件；超出范围的问题要在回报里以 `OUT-OF-SCOPE:` 标注，交给 Orchestrator 决定是否新开任务，而不是顺手改掉。
+- **Reviewer 必须独立重跑校验闸门**，不能只信 implementer 的回报。
+- **Reviewer 的返工清单必须可执行、带编号**（`REWORK 1: ...`），不写主观感受。
+- 一个任务**不通过校验闸门就不算完成**，Orchestrator 不得跳过。
+
+---
+
+## 2. 原子任务的定义
+
+一个"原子任务"必须同时满足：
+
+1. **单一关注点**：一个任务只解决一件事（一次 schema 变更、一个端点、一个模块迁移……）。
+2. **PR 大小**：理想 diff < ~200 行（结构性 sweep 任务可放宽，但应在卡上标 `[structural]` 并优先派给较强 implementer）。
+3. **边界处可绿**：任务完成时，整个仓库通过校验闸门（见下）。**一个任务"拥有"它所改代码对应的测试**——如果改动会让某些现有测试失败，修这些测试就属于这个任务的范围，不允许留红给下一个任务。
+4. **可独立验收**：验收标准是客观、可机械检查的断言，不依赖人的主观判断。
+5. **依赖显式**：通过 `Depends` 字段声明前置任务。没有声明依赖的任务，Orchestrator 可并行派发。
+
+---
+
+## 3. 任务卡格式
+
+每个任务在里程碑文档中以如下结构出现。Implementer 和 Reviewer 都只需要任务卡 + 本约定文件，**不需要读其它任务**即可工作。
+
+```markdown
+### M{n}-T{nn} — <标题> [structural?]
+
+- **Status**: `todo` | `in-progress` | `in-review` | `done`
+- **Depends**: M{n}-T{nn}, …（或 `none`）
+- **Context**: 1–2 句，为什么要做这个、它在里程碑里的位置。
+
+**Files**（精确到路径，标注动作）
+- `create  path/to/new_file.py`
+- `modify  path/to/existing.py`
+- `delete  path/to/old.py`
+
+**Steps**（便宜模型可直接照做的有序步骤）
+1. …
+2. …
+
+**Out of scope / 不要碰**
+- …（明确列出容易被误改的相邻区域，约束便宜模型漂移）
+
+**Acceptance criteria**（客观、可勾选；Reviewer 逐条核）
+- [ ] …
+- [ ] 校验闸门全绿（见 §4）
+
+**Reviewer checklist**（除验收标准外，强模型重点看的点）
+- …
+```
+
+---
+
+## 4. 校验闸门（每个任务结束都要全绿）
+
+在仓库根目录、激活 `.venv` 后执行：
+
+```bash
+# 1) 单元 / 集成测试（CI 同款，权威闸门）
+pytest
+
+# 2) Lint（pyproject 已配置 ruff，line-length=100）
+ruff check .
+
+# 3) 若本任务改动了任何 HTTP 路由 / schema：重导出 OpenAPI 并确认已提交
+python scripts/export_openapi.py
+git diff --exit-code openapi/    # 必须无未提交差异
+```
+
+- `pytest` 是**权威闸门**：`.github/workflows/pytest.yml` 跑的就是它，任何任务都不得让它变红。
+- 改了路由 / Pydantic schema 的任务，`openapi/openapi.json` 和 `openapi/openapi.yaml` 必须在同一任务里重新生成并提交（`openapi/` 纳入版本控制）。
+- 前端（M2/M3）相关任务的前端侧闸门（lint / typecheck / build）在对应里程碑文档里单独定义。
+
+---
+
+## 5. 提交与集成约定
+
+- 每个任务一个 commit，message 前缀任务 ID，例如：`M1-T03: unify data layer onto single app DB engine`。
+- 一个里程碑在一个 feature 分支上推进（如 `feature/m1-db-consolidation`），按任务依赖顺序合并。
+- 任务卡里的 `Status` 字段由 Orchestrator 维护，作为流水线的单一进度源。
+- 涉及**不可逆 / 数据破坏**的步骤（删旧 DB 文件、删 Grafana volume 等）一律不进自动化任务，只在文档里标为人工步骤（见 M1 的"人工操作"小节）。
+
+---
+
+## 6. 数据安全红线（贯穿所有里程碑，不可违反）
+
+1. **任何脚本 / migration 都不得删除或覆盖用户数据文件**（旧 `.db`、备份、volume）。删除只能是人工、事后、确认无误的独立步骤。
+2. 涉及历史数据的迁移**先在备份副本上演练**，再对真实库执行。
+3. 数据迁移脚本必须**幂等**且**搬完对账行数**，对不上立即中止并非零退出。
+4. 破坏性 Reviewer 一票否决：只要任务里出现"删文件 / drop 有数据的表 / truncate"，Reviewer 直接 REWORK，要求改为人工步骤。

+# M1 — 单库化地基（DB Consolidation）
+
+> 阅读前提：先读 [`README.md`](./README.md)（协作模型、任务卡格式、校验闸门、数据安全红线）。本文档只展开 M1 的现状、目标与原子任务。
+
+## 1. 目标
+
+把 location、poo 两个独立 SQLite 库合并进 `app.db`，收敛成**单库 + 单 engine + 单 DeclarativeBase + 单 Alembic 链**，清理项目早期散落的数据层代码，并移除 Grafana。历史数据零丢失。
+

+
+**三套数据层（散落点）**
+- `app/db.py`：`Base` + `engine`/`SessionLocal`/`get_db_session` —— 实际绑定 `settings.location_database_url`（即 location 库，命名有误导性）。
+- `app/models/base.py`：仅 `from app.db import Base` 转出。
+- `app/poo_db.py`：`PooBase` + `poo_engine`/`PooSessionLocal`/`get_poo_db_session` —— 绑定 `poo_database_url`。
+- `app/auth_db.py`：`AuthBase` + 带 `lru_cache` 的 `_get_auth_engine` / `get_auth_session_local` / `reset_auth_db_caches` / `get_auth_db_session` —— 绑定 `app_database_url`（真正的 app 库）。
+
+**模型与归属**
+- `app/models/auth.py`：`AuthUser`、`AuthSession`（`AuthBase` → app 库）
+- `app/models/config.py`：`AppConfigEntry`（`AuthBase` → app 库）
+- `app/models/public_ip.py`：`PublicIPState`、`PublicIPHistory`（`AuthBase` → app 库）
+- `app/models/location.py`：`Location`（`Base` → location 库），表 `location`，PK(`person`,`datetime`)，`latitude`/`longitude` NOT NULL，`altitude` nullable
+- `app/models/poo.py`：`PooRecord`（`PooBase` → poo 库），表 `poo_records`，PK(`timestamp`)，`status`/`latitude`/`longitude` NOT NULL
+- `app/models/__init__.py`：导出除 `PooRecord` 外的模型（`PooRecord` 单独存在）

+- `alembic_poo.ini` + `alembic_poo/`，head = `20260420_01_poo_baseline`
+
+**adoption / 启动链路**
+- `scripts/app_db_adopt.py`（常量 `APP_BASELINE_REVISION = "20260429_05_public_ip_monitor"`）
+- `scripts/location_db_adopt.py`、`scripts/poo_db_adopt.py`（含 legacy 校验：`EXPECTED_USER_VERSION`、表结构断言）
+- `scripts/run_migrations.py`：依次调用三个 adopt 函数，返回 `{"app","location","poo"}`
+- `app/main.py` lifespan：`ensure_runtime_dirs`（app/location/poo 三路径）、`ensure_auth_db_ready`、`ensure_location_db_ready`、`ensure_poo_db_ready`，再起 APScheduler 每 4h 检查 public IP
+
+**依赖与路由**
+- `app/dependencies.py`：`get_auth_db`（app session）、`get_db`（location session）、`get_poo_db`（poo session）、`get_app_settings`、`get_current_auth_session`、`get_homeassistant_client`、`get_ticktick_client`
+- `app/api/routes/location.py`：`POST /location/record`，依赖 `get_db`，**无鉴权**
+- `app/api/routes/poo.py`：`POST /poo/record`、`GET /poo/latest`，依赖 `get_poo_db`，**无鉴权**
+- `app/api/routes/homeassistant.py`：同时用 `get_db`（location）和 `get_poo_db`

+- `app/services/config_page.py`：`build_runtime_settings` 用到 `reset_auth_db_caches`；配置页 sections 暴露 `location_database_url` / `poo_database_url`（约 263–264 行）
+
+**测试耦合点（M1 必然要改）**
+- `tests/conftest.py`：`test_database_urls` 设三套环境变量；`ready_location_database` / `ready_poo_database` / `auth_database` / `location_client`（monkeypatch `app_db.engine`/`SessionLocal`）/ `poo_client`（monkeypatch `poo_db.poo_engine`/`PooSessionLocal`）
+- `tests/test_location.py` / `tests/test_poo.py`：用上述 client + 各自 adopt 脚本的 adoption 测试
+- `tests/test_deployment.py`：断言 `run_all_migrations()` 返回 `{app,location,poo}` 三库各自 revision；断言 entrypoint 不含 `*_db_adopt`
+- `tests/test_homeassistant_inbound.py`：monkeypatch `app.poo_db`
+- `tests/test_config.py` / `tests/test_public_ip.py` / `tests/test_smtp.py`：硬编码三套 URL / 路径
+- `reset_auth_db_caches` 被 `conftest`、`test_app`、`test_auth`、`test_deployment`、`test_ticktick` 引用
+
+## 3. 目标架构（M1 完成态）
+
+**单数据层 `app/db.py`**
+```python
+class Base(DeclarativeBase): ...
+# 绑定 settings.app_database_url 的 cached engine；建连时启用 WAL（PRAGMA journal_mode=WAL）
+def get_engine() -> Engine: ...
+def get_session_local() -> sessionmaker: ...
+def reset_db_caches() -> None: ...
+def get_db_session() -> Generator[Session, None, None]: ...
+```
+- 所有模型（auth / config / public_ip / location / poo）都继承这一个 `Base`。
+- 删除 `app/auth_db.py`、`app/poo_db.py`、`app/models/base.py`。
+- 依赖收敛为**单一** `get_db`（app session）；移除 `get_poo_db`、旧 `get_auth_db`。
+- 一条 Alembic 链（`alembic_app`），`location` / `poo_records` 成为其管理对象；删除 `alembic_location*` / `alembic_poo*`。
+- `config.py` 只保留 `app_database_url`；移除 location/poo 的 url 与 path。
+- `docker-compose.yml` 去掉 grafana service；删除 `grafana/`。
+- 数据搬迁由 `scripts/migrate_legacy_data.py` 一次性完成（不进 Alembic 链）。
+
+## 4. 任务依赖图
+
+```
+T01 (app 链建 location+poo 空表)
+ ├─► T02 (数据搬迁脚本)                 # 逻辑上需要新表存在

+T07 (文档 + OpenAPI 重导出)             # 收尾, 依赖 T03/T04/T05
+```
+
+`T01`、`T06` 无前置可先开；`T02` 依赖 `T01`；`T03` 依赖 `T01`；`T04`/`T05` 依赖 `T03`；`T07` 最后。

+
+## 5. 原子任务
+
+### M1-T01 — app 链新增 revision：建 `location` + `poo_records` 空表 `[schema]`
+
+- **Status**: `todo`
+- **Depends**: none
+- **Context**: 让 app 库的 Alembic 链能建出这两张表，schema 与旧库**完全一致**。本任务只动 schema，不搬数据、不移模型。
+
+**Files**
+- `create  alembic_app/versions/20260611_06_merge_location_poo_tables.py`
+- `modify  scripts/app_db_adopt.py`（更新 `APP_BASELINE_REVISION`）
+
+**Steps**
+1. 新 revision：`revision = "20260611_06_merge_location_poo_tables"`，`down_revision = "20260429_05_public_ip_monitor"`。
+2. `upgrade()` 用 `op.create_table` 手写建 `location` 与 `poo_records`，列/约束严格照抄现有 baseline（`location`: person TEXT, datetime TEXT, latitude REAL NOT NULL, longitude REAL NOT NULL, altitude REAL nullable, PK(person,datetime)；`poo_records`: timestamp TEXT, status TEXT, latitude REAL NOT NULL, longitude REAL NOT NULL, PK(timestamp)）。
+3. `downgrade()`：`op.drop_table("poo_records")` + `op.drop_table("location")`。
+4. 把 `scripts/app_db_adopt.py` 的 `APP_BASELINE_REVISION` 更新为新 head。
+
+**Out of scope / 不要碰**
+- 不要把 `Location` / `PooRecord` 模型改到 app Base（那是 T03）。
+- 不要触碰 `alembic_location*` / `alembic_poo*`（T03/T04 删）。
+- 不要在本 revision 里写任何数据拷贝。
+
+**Acceptance criteria**
+- [ ] 在一个全新临时 app 库上 `command.upgrade(alembic_app head)` 后，`sqlite_master` 含 `location`、`poo_records`、且与旧 baseline 表结构一致（`PRAGMA table_info` 对齐）。
+- [ ] `downgrade -1` 能干净回滚这两张表。
+- [ ] `APP_BASELINE_REVISION == "20260611_06_merge_location_poo_tables"`。
+- [ ] 校验闸门全绿（`pytest` 中 `test_deployment` 对 app head 的断言仍通过，因为它用的是常量）。
+
+**Reviewer checklist**
+- 表结构与旧 baseline **逐列逐约束**一致（类型 TEXT/REAL、nullable、PK 顺序）。
+- `down_revision` 正确指向旧 head，链上只有一个 head。
+
+---
+
+### M1-T02 — 数据搬迁脚本 `scripts/migrate_legacy_data.py`
+
+- **Status**: `todo`
+- **Depends**: M1-T01
+- **Context**: 把旧 `locationRecorder.db` / `pooRecorder.db` 的行幂等拷进 app 库的新表，搬完对账。**不进 Alembic 链**，人工运行一次。
+
+**Files**
+- `create  scripts/migrate_legacy_data.py`
+- `create  tests/test_migrate_legacy_data.py`
+
+**Steps**
+1. 入口 `migrate_legacy_data(app_url, location_url, poo_url, *, dry_run=False) -> dict`，CLI 默认从 env 读三个 url（即便 location/poo url 已从 `Settings` 移除，本脚本可直接读环境变量或接受 `--location-db`/`--poo-db` 参数，保持自包含）。
+2. 对每个旧库：若文件不存在 → 该表 `skipped`（**不报错**，保证 CI / 全新部署可安全 no-op）。
+3. 拷贝用 SQLite `ATTACH DATABASE '<old>' AS legacy` + `INSERT OR IGNORE INTO main.<table> SELECT <显式列> FROM legacy.<table>`（显式列名，禁用 `SELECT *`）。`INSERT OR IGNORE` 保证幂等（PK 冲突跳过）。
+4. 搬完对账：对每张表比对 `源行数` 与 `目标行数中来自源的部分`；目标行数 < 源行数则 `raise` 并以非零码退出。
+5. `dry_run` 模式只读统计、不写入。
+6. 打印每表结果：`{location: {source, copied, skipped, final}, poo_records: {...}}`。
+
+**Out of scope / 不要碰**
+- **绝不** `os.remove` / 覆盖任何旧文件（数据安全红线）。
+- 不修改 Alembic 链，不在 app 启动链路里调用本脚本。
+- 不改 `config.py`。
+
+**Acceptance criteria**
+- [ ] 单测：给定含 N 行的临时旧库 + 已 upgrade 的临时 app 库，运行后 app 库对应表有 N 行；**再运行一次**仍是 N 行（幂等）。
+- [ ] 单测：旧库文件不存在时该表返回 `skipped`，不抛异常，app 库该表保持为空。
+- [ ] 单测：构造"目标缺行"场景，断言对账失败抛错且退出码非零。
+- [ ] 脚本中不出现任何文件删除/覆盖调用（`grep -nE "os\.remove|unlink|shutil|truncate|DROP TABLE" scripts/migrate_legacy_data.py` 为空）。
+- [ ] 校验闸门全绿。
+
+**Reviewer checklist**
+- 幂等机制确实是 PK 冲突安全（`INSERT OR IGNORE` 或等价 upsert），不是靠"先清空目标"。
+- 对账逻辑会在丢行时**真的中止**（非零退出），不是只打印 warning。
+- 列名显式，与两表 schema 完全对应。
+
+---
+
+### M1-T03 — 统一数据层、模型、依赖、路由到单库 `[structural]`
+
+- **Status**: `todo`
+- **Depends**: M1-T01
+- **Context**: M1 的核心 sweep。把三套 engine/Base/session 收敛成 `app/db.py` 一套（绑 app 库、开 WAL），所有模型挂到同一个 `Base`，依赖收敛为单一 `get_db`，所有路由改用它。**本任务必须原子落地**——删除旧模块会同时打断所有 importer，无法分多次保持绿色。Orchestrator 可按下方 Steps 的自然分段派给较强 implementer。
+
+**Files**
+- `modify  app/db.py`（改写为统一数据层：`Base` + 绑 `app_database_url` 的 cached engine + WAL + `get_session_local` + `reset_db_caches` + `get_db_session`）
+- `delete  app/auth_db.py`
+- `delete  app/poo_db.py`
+- `delete  app/models/base.py`
+- `modify  app/models/location.py`（`from app.db import Base`）
+- `modify  app/models/poo.py`（改继承统一 `Base`，import 改 `app.db`）
+- `modify  app/models/auth.py`、`app/models/config.py`、`app/models/public_ip.py`（`AuthBase` → 统一 `Base`）
+- `modify  app/models/__init__.py`（补导出 `PooRecord`，保证 `from app import models` 注册所有表到同一 metadata）
+- `modify  app/dependencies.py`（单一 `get_db`；删 `get_poo_db`；`get_app_settings`/`get_current_auth_session` 改用 `get_db`）
+- `modify  app/api/routes/auth.py`、`pages.py`、`public_ip.py`、`ticktick.py`（`get_auth_db` → `get_db`）
+- `modify  app/api/routes/location.py`、`poo.py`、`homeassistant.py`（location/poo session 改用 `get_db`；删 `get_poo_db` 引用）
+- `modify  app/services/config_page.py`（`reset_auth_db_caches` → `reset_db_caches`）
+- `modify  app/main.py`（`import app.auth_db as auth_db` → 统一层；`get_auth_session_local` → `get_session_local`）
+- `modify  tests/conftest.py`、`tests/test_app.py`、`tests/test_auth.py`、`tests/test_ticktick.py`、`tests/test_homeassistant_inbound.py`、`tests/test_location.py`、`tests/test_poo.py`（import sweep + 把 location/poo client 改成写 app 库的统一 session；移除对 `app.poo_db`/`app.db`(location) monkeypatch 的依赖）
+
+**Steps**
+1. 改写 `app/db.py`：`Base(DeclarativeBase)`；沿用 `auth_db.py` 的 cached-engine + reset 模式但绑 `app_database_url`；为 sqlite 连接注册 `PRAGMA journal_mode=WAL`（用 `event.listens_for(engine, "connect")` 或建连后执行）。导出 `get_engine`/`get_session_local`/`reset_db_caches`/`get_db_session`。
+2. 模型 sweep：所有 `from app.auth_db import AuthBase` / `from app.poo_db import PooBase` / `from app.db import Base` 统一成 `from app.db import Base`；类继承统一 `Base`。`app/models/__init__.py` 增加 `from app.models.poo import PooRecord` 并补进 `__all__`。
+3. 删 `app/auth_db.py`、`app/poo_db.py`、`app/models/base.py`。
+4. 依赖 sweep：`app/dependencies.py` 留单一 `get_db`（yield 统一 session），删 `get_poo_db`；`get_app_settings`、`get_current_auth_session` 的 `Depends(get_auth_db)` → `Depends(get_db)`。
+5. 路由 sweep：所有 `Depends(get_auth_db)`、`Depends(get_poo_db)`、`Depends(get_db)` 统一为 `Depends(get_db)`（变量名 `auth_db_session`/`poo_db`/`db` 可保留，不强制改）。
+6. `app/services/config_page.py`：`reset_auth_db_caches` → `reset_db_caches`。
+7. `app/main.py`：把 `_run_scheduled_public_ip_check` / `ensure_auth_db_ready` 里的 `auth_db.get_auth_session_local()` 换成统一 `get_session_local()`。（lifespan 里 location/poo 的 ready 检查留到 T04 删。）
+8. 测试 sweep：`reset_auth_db_caches` → `reset_db_caches`（6 个文件）；conftest 的 `location_client`/`poo_client` 改成"写入统一 app session 即可"的形式（不再 monkeypatch 已删除的 `app.poo_db`/location `app.db`）；`test_homeassistant_inbound` 同理。
+
+**Out of scope / 不要碰**
+- 不删 `scripts/location_db_adopt.py` / `scripts/poo_db_adopt.py`，不改 lifespan 的 location/poo ready 调用（那是 T04，避免与本任务交叉冲突）。
+- 不动 `config.py` 的字段（T05）。
+- 不改业务逻辑（service 内部算法、HA 集成行为保持不变）。
+
+**Acceptance criteria**
+- [ ] `grep -rnE "auth_db|poo_db|PooBase|AuthBase|get_auth_db|get_poo_db|reset_auth_db_caches|app\.models\.base" app | grep -v __pycache__` 结果为空。
+- [ ] `app/db.py` 的 engine 绑定 `app_database_url`，sqlite 下 `PRAGMA journal_mode` 实测为 `wal`。
+- [ ] 所有模型 `Base.metadata.tables` 同时包含 auth/config/public_ip/location/poo_records 五类表。
+- [ ] `pytest` 全绿（含 location/poo/homeassistant_inbound 测试在单库下通过）。
+- [ ] `ruff check .` 无新增告警。
+
+**Reviewer checklist**
+- WAL 真的生效（实际连接 `PRAGMA journal_mode` 返回 `wal`），不是只写了注释。
+- location/poo 的读写在单库下行为不变（端点仍返回 200、行落库）。
+- 没有遗留指向已删模块的死 import；没有把业务逻辑顺手改了。
+- `get_db` 现在产出的是 app 库 session（不是旧 location 库）。
+
+---
+
+### M1-T04 — 收敛启动链路：lifespan + run_migrations，删除 location/poo adopt 脚本
+
+- **Status**: `todo`
+- **Depends**: M1-T03
+- **Context**: 单库后只需保证 app 库就绪；location/poo 的 adoption 链路整条退役。
+
+**Files**
+- `modify  app/main.py`（`ensure_runtime_dirs` 只建 app 路径；删 `ensure_location_db_ready`/`ensure_poo_db_ready` 及其调用与 import）
+- `modify  scripts/run_migrations.py`（只 `adopt_or_initialize_app_db`，返回 `{"app": ...}`）
+- `delete  scripts/location_db_adopt.py`
+- `delete  scripts/poo_db_adopt.py`
+- `delete  alembic_location.ini`、`alembic_location/`（含 env.py、versions）
+- `delete  alembic_poo.ini`、`alembic_poo/`
+- `modify  tests/test_deployment.py`（`run_all_migrations` 期望值改为单 `{"app": ...}`；删/改 legacy location/poo 迁移断言；保留"app DB 不存在则 fail-closed"用例）
+- `modify  tests/test_location.py`、`tests/test_poo.py`（删除针对已删 adopt 脚本的 adoption 测试；保留端点行为测试）
+- `modify  tests/conftest.py`（删 `_make_alembic_config`/`_make_poo_alembic_config`/`ready_location_database`/`ready_poo_database` 等已无意义的 fixture）
+
+**Steps**
+1. `app/main.py`：移除 `from scripts.location_db_adopt ...` / `poo_db_adopt` import；删两个 `ensure_*_db_ready` 函数及 lifespan 中调用；`ensure_runtime_dirs` 只处理 `settings.app_sqlite_path`。
+2. `scripts/run_migrations.py`：`run_all_migrations` 只返回 app 一项。
+3. 删除两套 adopt 脚本与两套 alembic 环境/ini。
+4. 测试：把 `test_migration_runner_*` 改成单库口径；删掉引用已删脚本常量（`LOCATION_BASELINE_REVISION` 等）的用例。
+
+**Out of scope / 不要碰**
+- 不动 `scripts/app_db_adopt.py` 的核心逻辑（仅 T01 已更新其常量）。
+- 不动数据搬迁脚本（T02）。
+
+**Acceptance criteria**
+- [ ] `grep -rnE "location_db_adopt|poo_db_adopt|alembic_location|alembic_poo" app scripts tests | grep -v __pycache__` 为空。
+- [ ] 仓库不再有 `alembic_location*` / `alembic_poo*` 文件。
+- [ ] `python -m scripts.run_migrations` 在全新临时 app 库上成功初始化（含 location/poo_records 表）。
+- [ ] 校验闸门全绿。
+
+**Reviewer checklist**
+- lifespan 仍对 app 库 fail-closed（缺库时明确报错），未弱化启动安全。
+- 没有残留对已删 alembic 环境的引用（包括 `.ini` 路径字符串）。

+
+### M1-T05 — config 去除 location/poo URL 与路径，清理配置页与测试硬编码
+
+- **Status**: `todo`
+- **Depends**: M1-T03
+- **Context**: 配置层只剩 `app_database_url`，运行时不再有 location/poo 库概念。
+
+**Files**
+- `modify  app/config.py`（删 `location_database_url`/`poo_database_url` 字段与 `location_sqlite_path`/`poo_sqlite_path` computed 属性）
+- `modify  app/services/config_page.py`（配置页 sections 移除 `location_database_url`/`poo_database_url` 展示项）

+
+**Out of scope / 不要碰**
+- 不动 `migrate_legacy_data.py`（它自带读旧库路径的能力，与 `Settings` 解耦）。
+- 不改其它配置项（SMTP / TickTick / HA 等）。
+
+**Acceptance criteria**
+- [ ] `grep -rnE "location_database_url|poo_database_url|location_sqlite_path|poo_sqlite_path" app tests | grep -v __pycache__` 为空。
+- [ ] 配置页渲染不再出现 location/poo DB URL 字段。
+- [ ] 校验闸门全绿。

+
+### M1-T06 — 移除 Grafana
+
+- **Status**: `todo`
+- **Depends**: none（可与 T01 并行）
+- **Context**: 可视化将由 M2 的 React 承担；Grafana 直接删除，不再 re-point。

+- `delete  grafana/`（`provisioning/`、`dashboards/` 全部）
+- `modify  tests/test_deployment.py`（若有针对 grafana service 的断言则同步移除）

+
+**Out of scope / 不要碰**
+- **不在脚本里删除** named volume `homeautomation_grafana_storage` 的实际数据卷——这是人工 ops 步骤（见 §6），compose 里移除声明即可。
+- 不动 app/migration service。
+
+**Acceptance criteria**
+- [ ] `docker-compose.yml` 不再含 `grafana` 与 `homeautomation_grafana_storage`。
+- [ ] 仓库不再有 `grafana/` 目录。

+### M1-T07 — 文档与 OpenAPI 收尾
+
+- **Status**: `todo`
+- **Depends**: M1-T03, M1-T04, M1-T05
+- **Context**: 让文档反映单库现实，并把"前后端不分离 / 三库不合并 / Grafana"约束在 architecture 文档中正式退役。
+
+**Files**
+- `modify  README.md`（三库 → 单库；删 location/poo DB 初始化与 adopt 说明；更新"运行测试"段落使其与实际测试一致）
+- `modify  docs/architecture-overview.md`（退役"三库不合并"；location/poo Alembic 链合并说明）
+- `modify  docs/roadmap.md`（勾掉 M1 范围项）
+- `run     python scripts/export_openapi.py` 并提交 `openapi/` 变更（location/poo 路由依赖在 T03 改过，schema 可能变化）
+
+**Acceptance criteria**
+- [ ] README / architecture 不再描述 location/poo 独立库与 adopt 脚本。
+- [ ] `python scripts/export_openapi.py` 后 `git diff --exit-code openapi/` 无未提交差异。
+- [ ] 校验闸门全绿。

+## 6. 人工操作 runbook（生产切换，不进自动化任务）
+
+按数据安全红线，下列步骤由人执行，**不**写进 implementer 任务：
+
+1. **备份**：停服前复制 `data/app.db`、`data/locationRecorder.db`、`data/pooRecorder.db` 到带时间戳的归档目录。
+2. **演练**：把上述备份恢复到 scratch 目录，先在副本上跑完整流程（升级 + `migrate_legacy_data.py --dry-run` 再实跑），核对行数。
+3. **部署新镜像**：新镜像的 migration job 会把 app 库升级到新 head，建出空的 `location` / `poo_records`。
+4. **搬数据**：在生产机运行 `python scripts/migrate_legacy_data.py`（指向归档前的旧库），核对对账输出。
+5. **验证**：app 起来后确认 location/poo 端点与历史查询正常、行数与旧库一致。
+6. **（事后，确认无误再做）撤旧库**：归档旧 `.db` 文件、删除 `homeautomation_grafana_storage` 卷。**这一步人工、可回退地保留归档，永不在脚本中自动执行。**
+
+## 7. 里程碑完成定义（Definition of Done）
+
+- 运行期只存在 `app.db` 一个库、一个 engine、一个 `Base`、一条 Alembic 链。
+- `grep` 不到任何 `auth_db` / `poo_db` / location 独立库 / adopt 脚本 / grafana 的残留引用。
+- 旧库历史数据已通过 `migrate_legacy_data.py` 搬入且对账通过。

+# M2 — 前端 v2（React SPA）
+
+> 阅读前提：先读 [`README.md`](./README.md)。M2 依赖 M1 完成（单库 + 干净的数据层 + API 建立在合并后的 schema 上）。
+
+## 1. 目标
+
+用 **React SPA** 取代现有 Jinja 页面，由 FastAPI **同源**托管（同一容器、同一 origin）。一步合并 roadmap 的"前端重写"与"前端做厚"：配置界面 + 数据可视化（热力图 / 地图，接管 Grafana）+ 记录的按需展示与小幅增删改。
+
+> **元目标（agentic 实验）**：这是用 agent 写 React 的试水，全程尽量不读代码。因此本里程碑**强约束 OpenAPI → 类型化 TS client 作为契约护栏**：后端 API 先稳，前端永远对着强类型契约写，便宜模型不易跑偏，reviewer 也有客观依据。
+
+## 2. 现状（M1 完成后）
+
+- 页面仍是服务端 Jinja：`app/api/routes/pages.py`（`GET/POST /config`、`/`、`/admin`、`POST /config/smtp/test`）+ `app/templates/`（`base/config/home/login.html`、`styles.css`）。
+- 鉴权：`get_current_auth_session`（读 `auth_session_cookie_name` cookie），server-side session + 每会话 `csrf_token` 内嵌在表单。
+- `app/main.py` 已 `app.mount("/static", StaticFiles(...))`。
+- 配置读写逻辑在 `app/services/config_page.py`（`build_config_sections` / `save_config_updates` / `build_runtime_settings`）。
+- 业务数据：单库中的 `location`、`poo_records`、`public_ip_state`、`public_ip_history`。
+
+## 3. 目标架构
+
+### 3.1 后端：JSON API + SPA 托管
+
+- 所有数据交互走 **JSON API**，统一前缀 `/api`（SPA 是客户端渲染，必须有 API——这与"同源/同容器"无关）。
+- FastAPI 既挂 `/api/*`，又挂 SPA 静态产物，并对非 `/api`、非静态资源的路径**回退到 `index.html`**（支持前端路由 deep-link）。
+- Jinja 页面在 SPA 达到功能对齐后移除。
+
+### 3.2 鉴权：复用 session cookie + SPA 版 CSRF
+
+- 继续用现有 **HttpOnly session cookie**（同源自动携带），M2 **不引入 token**（token 属 M3）。
+- CSRF（已定·简化版）：依赖 `SameSite=Lax` 的 session cookie——跨站发起的写请求（POST/PUT/PATCH/DELETE）**不会自动携带 cookie**，经典 CSRF 主路已被堵；再要求所有写请求带一个**自定义 header**（跨站无 CORS 预检发不出，且本应用不对外站开放 CORS）作为纵深防御。**不做 per-session token 比对**（个人自用场景足够）。`GET /api/session` 仍保留，用途是返回当前登录用户、引导 SPA（不再以下发/校验 `csrf_token` 为目的）。
+- 浏览器面向的所有新端点一律 session 保护；**裸 ingestion 端点（设备调用的 `POST /location/record`、`POST /poo/record`）维持现状到 M3**。
+
+### 3.3 前端工程
+
+- `frontend/`：**Vite + React + TypeScript**。
+- 组件库：**Mantine**（已定；批电池齐、TS 优先、视觉中性，最贴近此前 Vue 侧 Naive UI 的用法）。
+- API client：由后端 `openapi/openapi.json` **自动生成** TS 类型与请求函数（如 `openapi-typescript` + 轻量 fetch 封装）。**生成物入库** + `npm run codegen` + CI 校验"生成物与 openapi 同步"（已定）。fetch 封装统一带 cookie、写请求注入自定义 CSRF header、401 跳登录。
+- 可视化：**Leaflet**（已定）—— `react-leaflet` + `leaflet.heat`（热力图，**头号功能**）+ `leaflet.markercluster`（点多时聚合）+ OSM 栅格瓦片（零 key）。**地图封在一个自包含组件后面**（如 `<RecordsMap points mode onSelect>`，全应用只此处 import leaflet），数据获取/时间窗 state 在外面；这样将来若要换 **MapLibre GL** 是被隔离的局部重写，不波及其它。
+- 状态/数据请求：轻量即可（**TanStack Query**，已定），不引入重型框架。
+
+### 3.4 构建与部署
+
+- 多阶段 `Dockerfile`：node 阶段 `npm ci && npm run build` → 把 `frontend/dist` 拷进 python 镜像的静态目录；运行镜像不带 node。
+- compose 仍是单 app 容器（同源）。
+
+## 4. API 契约（M2 要落地的端点）
+
+> 全部 `/api` 前缀、session 保护、JSON 进出。具体 schema 在各任务里用 Pydantic 定义，并经 `export_openapi.py` 固化。
+
+| 分组 | 端点 | 用途 |
+| --- | --- | --- |
+| 会话 | `GET /api/session` | 返回当前用户 + csrf_token；未登录 401 |
+| 会话 | `POST /api/auth/login` | 账号密码登录，下发 session cookie |
+| 会话 | `POST /api/auth/logout` | 注销 |
+| 会话 | `POST /api/auth/password` | 改密（沿用现有强制改密语义）|
+| 配置 | `GET /api/config` | 返回配置 sections（secret 不回显）|
+| 配置 | `PUT /api/config` | 保存配置（留空保留旧 secret 语义不变）|
+| 配置 | `POST /api/config/smtp/test` | 触发测试发信 |
+| 数据 | `GET /api/locations` | location 记录查询（时间范围/分页，供地图/热力图）|
+| 数据 | `GET /api/poo` | poo 记录列表（分页）|
+| 数据 | `GET /api/public-ip` | 当前状态 + 变化历史 |
+| CRUD | `PATCH /api/locations/{person}/{datetime}` | 修正单条 location |
+| CRUD | `DELETE /api/locations/{person}/{datetime}` | 删除单条 location |
+| CRUD | `PATCH /api/poo/{timestamp}` | 修正单条 poo |
+| CRUD | `DELETE /api/poo/{timestamp}` | 删除单条 poo |
+
+> 记录 CRUD 依赖现有 PK 作行标识（location PK=`person+datetime`，poo PK=`timestamp`）。路径参数需对 `datetime`/`timestamp` 做 URL 编码处理。
+
+## 5. 已锁定决策（讨论后拍板）
+
+> 以下为与项目所有者讨论后**已定**的选择。**线框图本里程碑不画**——按本节 + 各任务卡描述，由实现侧自行合理排版（含移动端布局）。
+
+**技术选型**
+1. **组件库 = Mantine**。批电池齐、TS 优先、视觉中性、文档好，最贴近此前 Naive UI 的用法，利于 agent 产出一致 UI。
+2. **地图库 = Leaflet**（`react-leaflet` + `leaflet.heat` + `leaflet.markercluster`，OSM 栅格、零 key）。**封在自包含组件后**，预留将来迁 MapLibre 的接缝（见 §3.3）。
+3. **OpenAPI client = 生成物入库** + `npm run codegen` + CI 校验"与 openapi 同步"。
+4. **CSRF = 简化版**：`SameSite=Lax` cookie + 写请求带自定义 header，**不做 per-session token**（见 §3.2）。
+5. **前端栈**：Vite + React + TS + TanStack Query + Mantine。
+6. **Jinja**：SPA 功能对齐后**全量移除** `templates/` 与 `pages.py`。
+
+**信息架构 / UX**
+7. **首页主视图 = 地图（热力图为主）+ 时间范围选择器**。可视化优先级：**热力图（最重要）> 时间选择器（必须）> 散点点位/列表（辅助）**。
+8. **列表 = 辅助页面，分页**（默认页大小 ~100、有上限；前端换页取数，不拉全量）。
+9. **记录编辑/删除**：**location 靠点地图上的点**触发（不做 75k 行大列表）；**poo 靠列表 + 地图点位**。
+10. **配置入口**：config 作为普通页之一，由界面上一个**齿轮图标**进入。`/admin`、`/` 现状只是重定向到 `/config`，SPA **不需要单独 admin 页**；`/` 首页直接给地图主视图（概览 dashboard 列为**可选/后续**，非 M2 核心）。
+11. **响应式 = 要**（手机浏览器可用、合理移动端布局）。**PWA** 列为近期 backlog（见 `docs/future-ideas.md`），M2 设计即按移动端友好铺路。
+
+**范围边界**
+12. **CRUD = 改非主键字段 + 删单行**；主键（location=`person+datetime`、poo=`timestamp`）**不可改**；**不提供 UI 新建**（记录由设备 ingestion 产生）。
+13. **裸 ingestion 端点**（`POST /location/record`、`POST /poo/record`）**维持现状到 M3**，本里程碑不加保护、不改动。
+14. **trip / 轨迹连线**为**可选 / 后续**（5 分钟一点 + 手机记录较糙，先不做核心）。
+
+> 项目定位：个人自用、家庭特化、不开源——设计可按单用户场景简化，不为通用性过度抽象。

+- **Files**: `create frontend/`（Vite+React+TS 脚手架、`package.json`、`tsconfig.json`、eslint、vitest、`.gitignore`）、`frontend/src/api/`（codegen 产物 + fetch 封装，自动注入 `X-CSRF-Token`）、`frontend/README.md`、`npm run codegen` 脚本
+- **Steps**: 初始化 Vite React-TS；接 `openapi/openapi.json` 生成类型；写一个最小 App 壳 + 受保护路由骨架；fetch 封装统一带 cookie、写请求注入 CSRF header、401 跳登录。
+- **Acceptance**:
+  - [ ] `npm ci && npm run build` 成功产出 `frontend/dist`。
+  - [ ] `npm run lint`、`npm run typecheck`、`npm run test` 全绿（哪怕只有 1 个 smoke 测试）。

+### M2-T09 — 数据可视化 UI（热力图为主的地图）
+- **Status**: `todo` · **Depends**: M2-T06（数据来自 T03）
+- **Context**: 接管 Grafana 原职责，且**首页主视图就是这张地图**。优先级：**① 热力图（最重要）② 时间范围选择器（必须）③ 散点点位（辅助，主要服务编辑/删除）**。location：去过哪的密度；poo：狗最爱在哪拉。
+- **Acceptance**: 首页渲染热力图（location / poo）；**时间范围选择器生效、只取窗口内数据**（不拉全量）；散点层可切换、点选某点可进入编辑/删除（接 T10/T04）；location 点多时聚合；响应式（手机浏览器可用）；前端闸门全绿。

+---
+
+## 8. 前端校验闸门（前端任务每次结束都要全绿）
+
+在 `frontend/` 下：
+```bash
+npm ci
+npm run codegen      # 生成类型化 client；产物须与 openapi/openapi.json 同步
+npm run lint
+npm run typecheck
+npm run test
+npm run build        # 必须产出 dist
+```
+- 后端若同任务改了路由/schema，仍需根目录 `python scripts/export_openapi.py` 并提交 `openapi/`。
+- "codegen 产物与 OpenAPI 同步"应在 CI 校验（生成后 `git diff --exit-code`）。
+
+## 9. 里程碑完成定义（DoD）
+
+- 访问应用得到 React SPA；配置、可视化、记录增删改都在 SPA 内完成。
+- 所有浏览器交互走 `/api` JSON 端点，session + CSRF 保护；ingestion 裸端点维持现状（留给 M3）。
+- Jinja `templates/` 与 pages 路由移除；FastAPI 同源托管 SPA。

+# M3 — Token 鉴权与移动端（远期试水）
+
+> 阅读前提：先读 [`README.md`](./README.md)。M3 依赖 M2（已有 `/api` JSON 契约与 session 鉴权）。
+>
+> **定位**：远期、低投入、探索性。React Native 部分主要是"没做过、试试水"。范围**可能收缩**——其中**token 鉴权 + ingestion 端点收口**是有持久价值的安全改进，应优先；RN app 是加分项。Orchestrator 可只取前半。
+
+## 1. 目标
+
+1. 引入 **bearer token 鉴权**，让非浏览器客户端（移动端、设备脚本）能安全访问。
+2. 把 M2 暂时维持裸奔的 **ingestion 端点**（`POST /location/record`、`POST /poo/record`）收口到 token 鉴权下。
+3. 做一个 **React Native** 移动端，用类 OAuth 流程拿 token 后消费现有 `/api`。
+
+## 2. 现状（M2 完成后）
+
+- `/api/*` 走 session cookie + `X-CSRF-Token`。
+- `app/services/auth.py` 有 server-side session（`auth_sessions` 表，token_hash 存储）。
+- `POST /location/record`、`POST /poo/record` 仍**无鉴权**（设备/脚本裸调用）。
+
+## 3. 目标架构
+
+### 3.1 Token 模型
+- 新表 `auth_tokens`：`id`、`user_id`、`token_hash`(仅存哈希)、`label`(设备名)、`created_at`、`expires_at`(可空=长期)、`revoked_at`。
+- bearer 校验：`Authorization: Bearer <token>` → 哈希比对 `auth_tokens` → 命中且未撤销未过期则认定身份。
+
+### 3.2 类 OAuth 签发流程（无第三方的 Authorization Code 简化版）
+1. 移动端在**内置浏览器**打开 `/authorize?...`。
+2. 用户账号密码登录（走现有 session），页面展示"授权此设备"。
+3. 批准后服务端生成**一次性 authorization code**，重定向到 app 深链 `homeautomation://callback?code=...`。
+4. app 用 code 调 `POST /api/auth/token` 换取 bearer token 并存本地。
+> 简化兜底：批准页直接展示一次性 token 由 app 捕获。优先实现重定向 + code 交换的正规版。
+
+### 3.3 统一鉴权依赖
+- `/api` 的数据/CRUD 端点接受**session cookie 或 bearer**两者之一（同一套端点同时服务 Web 与移动端）。
+- ingestion 端点（location/poo record）改为**要求 bearer**。
+
+### 3.4 React Native
+- **Expo + TypeScript**，复用 M2 的 OpenAPI 类型化 client（共享契约）。
+- 内置浏览器走 §3.2 流程拿 token；之后所有请求带 `Authorization: Bearer`。
+
+## 4. 迁移注意（重要）
+- ingestion 端点一旦要求 bearer，**现有调用方（HA/设备脚本）必须先配置 token**，否则记录会中断。
+- 上线顺序：先签发 token 能力（T01–T02）→ 给现有设备配 token → 再对 ingestion 端点强制 bearer（T03），避免断流。可设一个过渡开关或灰度。
+
+## 5. 任务依赖图

+
+## 6. 原子任务（任务卡）
+
+### M3-T01 — token 数据模型 + Alembic 迁移
+- **Status**: `todo` · **Depends**: none（M2 完成后）
+- **Files**: `create app/models/token.py`、`alembic_app/versions/<new>_auth_tokens.py`；`modify app/models/__init__.py`；`create tests/test_token_model.py`
+- **Acceptance**:
+  - [ ] 迁移在全新库 upgrade 后建出 `auth_tokens` 表；downgrade 可回滚。
+  - [ ] token 仅以哈希存储（与 `auth_sessions` 同等强度），明文不入库。
+  - [ ] 校验闸门全绿。
+- **Reviewer**: 哈希算法/长度与现有 session token 一致；`expires_at` 可空语义明确。
+
+### M3-T02 — 签发流程：authorize 页 + code 交换端点
+- **Status**: `todo` · **Depends**: M3-T01
+- **Files**: `create app/api/routes/api/token.py`、`app/schemas/token.py`；前端 `/authorize` 页（M2 SPA 内）；`create tests/test_api_token.py`
+- **Acceptance**:
+  - [ ] 登录用户在 `/authorize` 批准后得到一次性 code；`POST /api/auth/token` 用 code 换取 bearer，code 一次性且短时效。
+  - [ ] 未登录访问 `/authorize` 跳登录；无效/过期 code 换取失败。
+  - [ ] 返回的 bearer 仅此一次明文出现，库中只存哈希。
+  - [ ] 校验闸门全绿。
+- **Reviewer**: code 一次性、绑定用户、短 TTL；深链 redirect 白名单校验，防开放重定向。
+
+### M3-T03 — 统一鉴权依赖 + ingestion 端点收口
+- **Status**: `todo` · **Depends**: M3-T02
+- **Files**: `modify app/dependencies.py`（新增"cookie 或 bearer"统一身份依赖）；`modify app/api/routes/location.py`、`poo.py`（要求 bearer，带过渡开关）；`modify tests`
+- **Acceptance**:
+  - [ ] `/api` 数据/CRUD 端点用合法 bearer 可访问（等价于 session）。
+  - [ ] ingestion 端点：带合法 bearer 通过，缺/错 token 在强制模式下 401；过渡开关可临时放行（默认关）。
+  - [ ] 撤销的 token 立即失效。
+  - [ ] 校验闸门全绿。
+- **Reviewer**: 过渡开关默认安全（强制）；bearer 与 session 两路鉴权不产生绕过；ingestion 行为变更有测试覆盖。
+
+### M3-T04 — Web 端 token 管理 UI
+- **Status**: `todo` · **Depends**: M3-T03
+- **Acceptance**: 在 SPA 内可列出已签发设备 token（label/创建时间/最近使用）、可撤销；撤销后该 token 立即失效；前端闸门全绿。
+
+### M3-T05 — React Native app（试水）
+- **Status**: `todo` · **Depends**: M3-T03 · `[experimental]`
+- **Files**: `create mobile/`（Expo + TS，复用 OpenAPI 类型化 client）
+- **Acceptance**:
+  - [ ] 内置浏览器走签发流程拿到 token 并安全存储（Keychain/Keystore）。
+  - [ ] 至少跑通：登录拿 token → 拉取一类数据展示 → 记一条 ingestion。
+  - [ ] `npm run lint`/`typecheck`/`build`(或 Expo 等价) 全绿。
+- **Reviewer**: token 存安全存储而非明文；client 基于共享 OpenAPI 类型。
+
+### M3-T06 — 文档收尾
+- **Status**: `todo` · **Depends**: M3-T05
+- **Acceptance**: README/architecture 增 token 鉴权与移动端说明；roadmap 勾选 M3；`openapi/` 同步。
+
+## 7. 里程碑完成定义（DoD）
+- 存在 bearer token 鉴权与签发流程；token 仅哈希存储、可撤销。
+- ingestion 端点已收口到 bearer（过渡完成后强制）。
+- `/api` 同时支持 session 与 bearer。
+- （加分）React Native app 能拿 token 并消费 `/api`。
+- 后端 + 前端 + 移动端各自校验闸门全绿，`openapi/` 入库。
+
+> 提醒：本里程碑探索性强，T05 可作为独立试水随时叫停，不影响 T01–T04 带来的安全收口价值。

+# Public IPv4 Monitor 与邮件通知
+
+本文档说明当前 public IPv4 monitor 与 SMTP 邮件通知能力的职责边界和运行方式。
+
+## 当前范围
+
+当前实现只覆盖一个很小的通知能力：
+
+- 定期或手动检查当前公网 IPv4
+- 将当前状态和变化历史持久化到 app DB
+- 仅在公网 IPv4 发生变化时发送一封英文纯文本邮件
+
+当前明确不包含：
+
+- Namecheap API 自动更新
+- IPv6 检查
+- 错误告警邮件
+- 重复提醒 / 升级告警
+- Telegram / Slack / Discord 通知
+- 完整通知中心或模板系统
+
+## 数据存储
+
+当前数据全部进入 app DB。
+
+相关表：
+
+- `public_ip_state`
+  - 保存当前状态
+  - 逻辑上通常只有一行
+- `public_ip_history`
+  - 保存首次发现和变化历史
+
+当前不会把 public IP 状态放进 `app_config`。
+
+## 检查结果语义
+
+一次检查会返回以下四种结果之一：
+
+- `first_seen`
+- `unchanged`
+- `changed`
+- `error`
+
+行为约束：
+
+- `first_seen`：写入当前 IP 和首条 history，但不发通知邮件
+- `unchanged`：只更新时间和状态，不写 history，不发邮件
+- `changed`：更新 `previous_ipv4` / `current_ipv4` / `last_changed_at`，写入 history，并发送邮件
+- `error`：保留已有有效 IP，不写伪 history，也不发邮件
+
+## 手动检查与定时检查
+
+手动检查入口：
+
+- `GET /public-ip/check`
+
+约束：
+
+- 需要现有鉴权
+- 响应不暴露 IP 本身
+- 只返回非敏感检查结果
+
+定时检查：
+
+- 应用启动时注册 APScheduler job
+- 默认每 4 小时执行一次
+- 与手动检查复用同一套 public IP check + notify 逻辑
+
+## SMTP 通知
+
+当前通知发信复用现有 SMTP sender。
+
+依赖的配置项：
+
+- `SMTP_ENABLED`
+- `SMTP_HOST`
+- `SMTP_PORT`
+- `SMTP_USERNAME`
+- `SMTP_PASSWORD`
+- `SMTP_FROM_NAME`
+- `SMTP_FROM_ADDRESS`
+- `SMTP_TO_ADDRESS`
+- `SMTP_USE_STARTTLS`
+
+其中：
+
+- `SMTP_FROM_NAME` 用于邮件头显示名
+- `From` 头会渲染成 `Name <mail@domain>`
+- SMTP envelope sender 仍然使用纯邮箱地址，保持兼容性
+
+## 通知触发条件
+
+只有在 `changed` 时发邮件。
+
+不会发邮件的情况：
+
+- `first_seen`
+- `unchanged`
+- `error`
+
+这使得同一 IP 状态不会被重复通知，因为在首次变更之后，后续重复检查会变成 `unchanged`。
+
+## 邮件内容
+
+当前邮件标题固定为：
+
+- `Public IP changed`
+
+正文为英文纯文本，至少包含：
+
+- previous IP
+- current IP
+- detected time
+
+当前正文还会附带一句 Namecheap trusted IP 的人工更新提示。
+
+## 失败处理
+
+当前通知发送是“尽力而为”的附加动作：
+
+- public IP 状态持久化先完成
+- 邮件发送失败不会回滚 public IP 状态
+- 失败只记录 warning 日志
+
+这样可以避免通知链路反过来影响主检查流程。

+# Roadmap
+
+本文档记录 `home-automation` 在 `v1.0.3` 之后的下一阶段规划。这一阶段不是小修补，而是几次较大的结构性改动：单库化、前端重写、以及远期的移动端试水。
+
+> 每个里程碑的**可执行原子任务**展开在 [`docs/design/`](./design/README.md)：M1 [`m1-db-consolidation.md`](./design/m1-db-consolidation.md)、M2 [`m2-frontend-v2.md`](./design/m2-frontend-v2.md)、M3 [`m3-token-mobile.md`](./design/m3-token-mobile.md)。这些文档为 Orchestrator→Implementer→Reviewer 的多模型流水线设计。
+
+## 当前基线（v1.0.3）
+
+- FastAPI + 服务端 Jinja 模板页面（目前只有 `/login`、`/config`）
+- 三个独立 SQLite 库：
+  - App DB：`sqlite:///./data/app.db`
+  - Location DB：`sqlite:///./data/locationRecorder.db`
+  - Poo DB：`sqlite:///./data/pooRecorder.db`
+- 三条独立 Alembic 链：`alembic_app/`、`alembic_location/`、`alembic_poo/`
+- 单 admin 鉴权（Argon2 + server-side session cookie）
+- Public IPv4 monitor、SMTP 通知、Location / Poo recorder、Home Assistant in/out、TickTick OAuth
+- 数据可视化目前由 Grafana provisioning 承担（仅 location / poo dashboard）
+- 已有 OpenAPI 导出脚本：`scripts/export_openapi.py`
+
+## 本阶段正式退役的架构约束
+
+`docs/architecture-overview.md` 里有几条当时刻意写死的约束，这一阶段明确退役：
+
+- **“不引入前后端分离”** → 退役。本阶段改为 React SPA（仍由 FastAPI 同源托管，但渲染移到客户端）。
+- **“三个独立 DB 不合并”** → 退役。本阶段把 location / poo 合并进 `app.db`。
+- **Grafana 作为可视化方案** → 退役。可视化由 React 前端自己承担（热力图、地图等）。
+
+保持不变的约束：
+
+- 继续使用 **SQLite**，本阶段不上 Postgres。
+- 不引入 Notion。
+
+## 里程碑总览
+
+| 里程碑 | 主题 | 一句话 |
+| --- | --- | --- |
+| **M1** ✅ | 单库化地基 | 把三库合并成单一 `app.db`，清理散落数据层，删掉 Grafana |
+| **M2** | 前端 v2 | React SPA 取代 Jinja，承载 config + 可视化 + 记录增删改 |
+| **M3** | 开放与移动端（远期试水） | token 鉴权 + React Native 移动端 |
+
+排序原则：**先清地基，再在干净结构上盖楼。** M2 的新 API 和 React 必须建立在合并后的单库之上，否则就是在准备推倒的旧数据层上盖新楼、之后回头返工。
+
+---
+
+## M1 — 单库化地基（✅ 已完成）
+
+### 目标
+
+把 location / poo 两个独立库合并进 `app.db`，借机清理项目早期散落各处的数据访问代码，并移除 Grafana。
+
+### 范围
+
+- **Alembic 收敛为单链（app 链）**：location / poo 的表此后纳入 app 链管理；`alembic_location/`、`alembic_poo/` 退出活跃使用（保留在 git 历史）。
+- **新建表（schema only）**：在 app 链上加一条 upgrade revision，把原来两个旧库里的表**原样**建到 `app.db` 中。Alembic **不需要知道任何旧数据**——它只负责把 app DB 往上升一个版本、建出这两张新表。
+- **数据搬迁交给独立脚本**：`scripts/migrate_legacy_data.py`（见下方“迁移策略”），手动跑一次。
+- **配置层收敛**：去掉 `LOCATION_DATABASE_URL` / `POO_DATABASE_URL`，统一到 `APP_DATABASE_URL`。
+- **开启 SQLite WAL**：单文件 + Web + APScheduler 并发写入，开 WAL 更稳。
+- **删除 Grafana**：移除 compose 中的 grafana service、`grafana/provisioning/`、`grafana/dashboards/`。直接删除，不再 re-point datasource。
+- **更新文档**：README、architecture-overview 同步反映单库现实。
+
+### 注意
+
+- **可视化空窗可接受**：M1 删掉 Grafana 后、到 M2 React 可视化落地之前会有一段没有可视化面板的时间。已确认可以接受。
+- **历史数据是第一优先级，绝不能丢**（见“数据安全原则”）。
+
+---
+
+## 迁移策略（M1 核心）
+
+职责拆分得很清楚：**Alembic 管 schema，脚本管数据。**
+
+### Alembic revision（只建结构）
+
+- 一条 app 链上的 upgrade revision，建出与旧库**完全相同**的表结构。
+- 确定性、与环境无关：在生产机、CI、全新部署上都一样地建空表，不依赖任何旧文件是否存在。
+- 本步**只原样挪表，不顺手改 schema**。任何表结构清理留到之后一条单独的 migration 去做——不可替代的历史数据，一次只承担一种风险。
+
+### 数据搬迁脚本（`scripts/migrate_legacy_data.py`）
+
+- 把旧 `locationRecorder.db` / `pooRecorder.db` 里的行，拷进 `app.db` 的新表（SQLite `ATTACH DATABASE` 或单独连接均可）。
+- **幂等**：重复运行不会重复插入。
+- **搬完对账**：逐表核对源 / 目标行数，对不上就报错中止。
+- 只在生产机上**手动跑一次**，不进 Alembic 永久链路（避免把一次性历史搬迁焊死进每次全新建库都要跑的链路里）。
+
+### 旧库的“撤掉”
+
+- “撤掉旧库” = ① 配置不再指向它们 + ② 文件**归档保留**。
+- **绝不**在任何脚本 / migration 里 `os.remove` 旧文件——那不可逆，且踩数据安全红线。
+- 真正的删除是**人工、最后、确认无误之后**单独的一步。
+
+---
+
+## 数据安全原则
+
+历史数据（location / poo 记录）是这个项目里最不可替代的东西，迁移期间一律按以下原则：
+
+1. **迁移前先归档**旧 `.db` 文件一份。
+2. **先在副本上演练**：把每日备份恢复到一个 scratch 目录，在副本上跑完整迁移、核对行数无误，再对真实库动手。
+3. **脚本幂等 + 行数对账**，对不上立即中止。
+4. **旧文件只读归档、绝不自动删除**，删除是事后人工动作。
+
+---
+
+## M2 — 前端 v2（React SPA）
+
+### 目标
+
+用 React SPA 取代现有 Jinja 页面，由 FastAPI 同源托管（同一容器、同一 origin）。这一步合并了“前端重写为 React”和“前端做厚”两件原本分开的事——它们本质是同一坨活。
+
+> 备注：React 是一次 agentic programming 试水。之前只手写过 Vue、没手写过 React，这一轮想全程靠 agent、尽量不读代码地把它做出来。OpenAPI 导出 → 生成类型化 TS client 作为 agent 的契约护栏，正好服务这个目标。
+
+### 范围
+
+- **React SPA**，FastAPI 挂载打包后的静态产物（同源，省掉 CORS）。
+- **Config 界面**：取代现有 Jinja config 页。
+- **数据可视化**：热力图、地图等，接管原先 Grafana 干的事。
+- **按需展示 DB 数据**（例如 poo 记录）。
+- **记录的小幅增删改**：用于修正不准确的记录。
+
+### 后端配套
+
+- **补一套 JSON API**：SPA 是客户端渲染，需要后端提供 config 读写、数据查询、记录 CRUD 等 JSON 端点。（同源不等于不需要 API——API 是“客户端怎么拿数据”，与文件托管在哪无关。）
+- **鉴权**：浏览器面向的新端点（含记录 CRUD）复用现有 session cookie 保护。
+- **类型化 client**：用 `scripts/export_openapi.py` 的输出生成 TS client。
+
+### 鉴权边界（与 M3 衔接）
+
+- 现在那个“裸 API 记小狗日志”的 ingestion 端点（设备 / 脚本调用，非浏览器）**维持现状到 M3**。
+- M2 新增的、浏览器调用的 CRUD 端点，用 session 保护即可，本步不引入 token。
+
+---
+
+## M3 — 开放与移动端（远期试水）
+
+### 目标
+
+引入 token 鉴权并做一个 React Native 移动端。**明确是很远期、低投入的试水**——先把 React 前端做出来，之后才会碰移动端，且主要是想试试没做过的 React / React Native。
+
+### 范围
+
+- **OAuth-lite token 签发**：移动端在内置浏览器里用账号密码登录，走一遍类 OAuth 流程，服务端签发一个 bearer token 给 app 存起来使用。（本质是没有第三方的 Authorization Code 简化版。）
+- **React Native 移动端**：试水性质。
+- **给 ingestion 端点上 token**：把 M2 暂时维持裸奔的设备端点收口到 token 鉴权下。
+
+### 为什么放最后
+
+- 移动端是这一阶段最远期、最不确定的部分。
+- token 主要是移动端的前置条件；Web 端 React 用现有 session cookie 即可，不需要为它提前引入 token。

+
+## Dev Proxy (local development)
+
+`npm run dev` starts Vite on port 5173. The Vite config proxies API/auth paths
+to the FastAPI backend running on port 8000:
+
+| Proxied path | Backend URL |
+|---|---|
+| `/api/*` | `http://localhost:8000` |
+| `/login` | `http://localhost:8000` |
+| `/logout` | `http://localhost:8000` |
+| `/static/*` | `http://localhost:8000` |
+| `/docs` | `http://localhost:8000` |
+| `/openapi.json` | `http://localhost:8000` |
+
+To develop locally:
+1. Start the backend: `uvicorn app.main:app --reload --host 0.0.0.0 --port 8000`
+2. Start the frontend: `cd frontend && npm run dev`
+3. Open `http://localhost:5173` — the app proxies all API calls to the backend.
+
+Since the dev server proxies the session cookie path, auth flows work exactly as
+they would in the deployed (same-origin) setup.
+
+## Adding a New Page + Typed Query
+
+This is the pattern every task T07–T10 follows to wire up a real page:
+
+### 1. Run codegen (if the OpenAPI contract changed)
+
+```bash
+npm run codegen
+```
+
+The generated `src/api/schema.d.ts` is committed to the repo. CI enforces that
+the file is in sync with `openapi/openapi.json` via:
+```bash
+npm run codegen && git diff --exit-code frontend/src/api/schema.d.ts
+```
+
+### 2. Import the typed client
+
+```typescript
+// src/pages/SomePage.tsx
+import apiClient from '../api/client'
+```
+
+### 3. Write a typed TanStack Query
+
+```typescript
+import { useQuery } from '@tanstack/react-query'
+import apiClient from '../api/client'
+
+function usePooRecords(limit = 100) {
+  return useQuery({
+    queryKey: ['poo', { limit }],
+    queryFn: async () => {
+      const res = await apiClient.GET('/api/poo', { params: { query: { limit } } })
+      // res.data is typed as PooResponse | undefined
+      // On non-2xx the middleware throws ApiError; TanStack Query catches it.
+      return res.data
+    },
+  })
+}
+```
+
+The `params.query` and `params.path` objects are fully typed from `schema.d.ts`.
+TypeScript will error if you pass unknown query params or mistype a path param.
+
+### 4. Write a typed mutation (write request)
+
+```typescript
+import { useMutation, useQueryClient } from '@tanstack/react-query'
+import apiClient from '../api/client'
+
+function useDeletePoo() {
+  const qc = useQueryClient()
+  return useMutation({
+    mutationFn: (timestamp: string) =>
+      apiClient.DELETE('/api/poo/{timestamp}', {
+        params: { path: { timestamp } },
+      }),
+    onSuccess: () => qc.invalidateQueries({ queryKey: ['poo'] }),
+  })
+}
+```
+
+The middleware (`src/api/client.ts`) automatically injects the `X-CSRF-Token` header
+on all non-GET/HEAD requests (sourced from `getCsrfToken()`). You do not need to
+handle CSRF manually in page code.
+
+### 5. Add the route in App.tsx
+
+```typescript
+// App.tsx
+import { SomePage } from './pages/SomePage'
+
+// Inside <Routes>:
+<Route path="/some-path" element={<SomePage />} />
+// or, if protected:
+<Route
+  element={
+    <ProtectedRoute>
+      <AppLayout />
+    </ProtectedRoute>
+  }
+>
+  <Route path="/some-path" element={<SomePage />} />
+</Route>
+```
+
+## OpenAPI codegen + CI sync rule
+
+`src/api/schema.d.ts` is committed to the repository (not gitignored).
+
+**Rule**: whenever `openapi/openapi.json` changes (any backend task that modifies
+a route or schema), CI must run:
+```bash
+cd frontend && npm run codegen
+git diff --exit-code frontend/src/api/schema.d.ts
+```
+If the file has changed but the new version was not committed, CI fails.
+
+To update manually after a backend change:
+```bash
+cd frontend
+npm run codegen
+git add src/api/schema.d.ts
+git commit -m "M2-Txx: update generated OpenAPI types"
+```
+
+## Production Build
+
+The production build (`npm run build`) writes static files to `frontend/dist/`.
+In the deployed setup (M2-T11 onwards), FastAPI serves `dist/` as a static
+directory and falls back to `dist/index.html` for all non-`/api` paths,
+enabling client-side routing with deep links.
+
+The multi-stage Dockerfile (M2-T12) builds the frontend in a Node container and
+copies only `dist/` into the Python image — the production image does not
+contain Node or npm.
