 # Home Automation Backend
 
-![CI-Short](https://code.wanderingbadger.dev/tliu93/home-automation-backend.git/actions/workflows/short-tests.yml/badge.svg)
+这是当前 `home-automation` 项目的首个 Python 版本。
+
+当前系统已经包含：
+
+- FastAPI Web 应用与服务端模板页面
+- SQLite + SQLAlchemy + Alembic 的三库结构
+- username/password + server-side session 鉴权
+- runtime config 页面与 app DB 持久化
+- public IPv4 monitor、历史持久化与定时检查
+- SMTP 配置、测试发信与 public IPv4 changed 邮件通知
+- location recorder
+- poo recorder
+- Home Assistant inbound / outbound integration
+- TickTick OAuth 与 action task 集成
+- pytest 测试与 OpenAPI 导出脚本
+- Docker / Compose 部署入口
+
+当前明确不包含：
+
+- Notion 模块
+
+## 当前配置现实
+
+当前系统仍然是三个独立的 SQLite 数据库文件，而不是单一数据库：
+
+- `app` 级共享数据使用自己的 DB 文件
+- `location` 模块使用自己的 DB 文件
+- `poo` 模块使用自己的 DB 文件
+
+当前阶段明确不借这次重构把这些 DB 合并。配置层已经显式反映这一点：
+
+- `APP_DATABASE_URL`
+- `LOCATION_DATABASE_URL`
+- `POO_DATABASE_URL`
+
+目前 auth、`location` 和 `poo` 都已经接到各自独立的数据库文件。
+
+其中 `app` 级共享 DB 当前主要用于：
+
+- 单个 admin 用户
+- server-side session
+- runtime config 持久化
+- public IPv4 当前状态与变化历史
+
+这部分现在也使用 Alembic 管理：
+
+- `app db` 不会在应用启动时自动创建
+- 需要先运行 `python scripts/app_db_adopt.py`
+- 这个脚本会创建新 DB 并建好 schema
+
+## 当前目录
+
+主要目录如下：
+
+- `app/`: FastAPI 应用代码
+- `alembic_app/`: App DB 的 Alembic migration 环境
+- `alembic_location/`: Location DB 的 Alembic migration 环境
+- `alembic_poo/`: Poo DB 的 Alembic migration 环境
+- `tests/`: pytest 测试
+- `docs/`: 当前系统说明文档
+- `scripts/`: 辅助脚本，例如 OpenAPI 导出
+
+## 依赖管理
+
+项目现在采用 `pip-tools` 管理依赖：
+
+- 生产依赖源文件：`requirements.in`
+- 开发依赖源文件：`dev-requirements.in`
+- 编译产物：
+  - `requirements.txt`
+  - `dev-requirements.txt`
+
+更新依赖时建议使用：
+
+```bash
+python -m venv .venv
+source .venv/bin/activate
+pip install pip-tools
+pip-compile requirements.in
+pip-compile dev-requirements.in
+```
+
+如果要升级某个依赖，可以用：
+
+```bash
+pip-compile --upgrade-package fastapi requirements.in
+pip-compile dev-requirements.in
+```
+
+## 本地启动
+
+建议使用 Python 3.11 或以上版本。
+
+1. 创建虚拟环境并安装依赖
+
+```bash
+python -m venv .venv
+source .venv/bin/activate
+pip install -r dev-requirements.txt
+```
+
+2. 准备环境变量
+
+```bash
+cp .env.example .env
+```
+
+3. 初始化数据库
+
+```bash
+python -m scripts.run_migrations
+```
+
+4. 启动服务
+
+```bash
+uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
+```
+
+启动后可访问：
+
+- 应用首页：`http://localhost:8000/`
+- 健康检查：`http://localhost:8000/status`
+- Swagger UI：`http://localhost:8000/docs`
+- ReDoc：`http://localhost:8000/redoc`
+
+## 数据库与 Alembic
+
+当前默认使用 SQLite，并区分三个数据库文件：
+
+- App DB：`sqlite:///./data/app.db`
+- Location DB：`sqlite:///./data/locationRecorder.db`
+- Poo DB：`sqlite:///./data/pooRecorder.db`
+- 数据目录：`./data/`
+
+初始化 migration 环境后，可继续添加模型并生成迁移：
+
+当前 `app`、`location` 和 `poo` 都已经有各自独立的 Alembic 链路。
+
+- App Alembic 环境：`alembic_app.ini` + `alembic_app/`
+- Location Alembic 环境：`alembic_location.ini` + `alembic_location/`
+- Poo Alembic 环境：`alembic_poo.ini` + `alembic_poo/`
+- 统一 migration job：`python -m scripts.run_migrations`
+- App DB 初始化：`python scripts/app_db_adopt.py`
+- Location DB 接管 / 初始化：`python scripts/location_db_adopt.py`
+- Poo DB 接管 / 初始化：`python scripts/poo_db_adopt.py`
+
+## 基础鉴权
+
+当前项目提供一个单用户 admin 鉴权层，用于保护配置页面与管理能力。
+
+- 认证模型：`username/password`
+- 会话模型：server-side session + cookie
+- 当前主要受保护页面：`/config`
+- 当前公开页面：`/login`
+- 当前公开 API：现有业务 API 暂未在这一轮统一收口到 auth 下
+
+安全实现的当前边界：
+
+- 密码使用 Argon2 做哈希存储
+- session cookie 使用 `HttpOnly`
+- `Secure` 默认随 `APP_ENV` 切换：非 development 时默认开启
+- `SameSite=Lax`
+- 登录表单和登出表单都有基础 CSRF 防护
+
+首次启动时，如果 `APP_DATABASE_URL` 对应的 auth DB 里还没有用户，应用会使用：
+
+- `AUTH_BOOTSTRAP_USERNAME`
+- `AUTH_BOOTSTRAP_PASSWORD`
+
+创建初始 admin 用户。当前默认就是：
+
+- username: `admin`
+- password: `admin`
+
+首次登录后会被要求立即修改密码。这个 bootstrap 只用于首个用户落库，不是后续的完整配置管理方案。
+
+当前前端主要有两条页面路径：
+
+- `/login`
+- `/config`
+
+无论是本地 `host:port` 还是反向代理后的域名访问，登录成功后都使用相对路径跳转到 `/config`。
+
+## Config 持久化
+
+当前 config 页面不会把修改写回 `.env`。
+
+当前原则是：
+
+- `.env` 只负责 bootstrap / fallback
+- app 启动先从 `.env` 读取数据库地址等基础配置
+- 请求期读取配置时，优先使用 app DB 中的 `app_config` 表
+- 如果数据库里没有对应值，再 fallback 到 `.env`
+
+这意味着：
+
+- location / poo / app DB 地址仍然属于 bootstrap 范畴
+- 运行时可编辑配置主要通过 `app_config` 表持久化
+- token / secret 这类运行时必须可取回的配置，目前允许明文存储在 config 表中
+- 登录密码仍然单独使用 Argon2 哈希，不走 config 表明文存储
+
+当前已经接入 config 页面的运行时配置包括：
+
+- 基础系统配置
+- auth cookie 相关配置
+- SMTP 基础配置
+- TickTick OAuth 配置
+- Home Assistant 配置
+
+其中 SMTP password 与其他 secret 字段一致：
+
+- 页面不明文回显
+- 留空提交时保留旧值
+- 用于测试发信与自动通知时不会写入响应
+
+## Public IPv4 Monitor
+
+当前系统已经提供最小可用的 public IPv4 monitor：
+
+- 使用单一 provider 检查当前公网 IPv4
+- 将状态与变化历史持久化到 app DB
+- 提供受保护的手动检查入口：`GET /public-ip/check`
+- 启动时注册 APScheduler job，默认每 4 小时检查一次
+
+当前 app DB 中与此功能相关的新表：
+
+- `public_ip_state`
+- `public_ip_history`
+
+状态语义如下：
+
+- `first_seen`：首次发现当前公网 IPv4
+- `unchanged`：与上次状态一致
+- `changed`：公网 IPv4 发生变化
+- `error`：provider 请求失败或返回无效值
+
+## SMTP 与邮件通知
+
+当前系统已经提供最小可用的 SMTP 能力：
+
+- SMTP 配置可在 `/config` 页面填写并保存到 `app_config`
+- 可通过 config 页面发送测试邮件
+- 邮件 `From` 头支持显示名，例如 `Home Automation <sender@example.com>`
+
+当前 SMTP 配置项包括：
+
+- `SMTP_ENABLED`
+- `SMTP_HOST`
+- `SMTP_PORT`
+- `SMTP_USERNAME`
+- `SMTP_PASSWORD`
+- `SMTP_FROM_NAME`
+- `SMTP_FROM_ADDRESS`
+- `SMTP_TO_ADDRESS`
+- `SMTP_USE_STARTTLS`
+
+当前 public IPv4 monitor 已与 SMTP sender 接通，但只处理一个很小的通知场景：
+
+- 当 public IPv4 check 结果为 `changed` 时，自动发送一封英文纯文本邮件
+
+以下情况不会发邮件：
+
+- `first_seen`
+- `unchanged`
+- `error`
+
+当前通知邮件内容固定，不提供模板系统，正文会包含：
+
+- previous IP
+- current IP
+- detected time
+
+手动测试时，如果需要再次模拟一次 IP 变化，可以临时修改 `public_ip_state.current_ipv4` 为一个保留测试地址，然后再次调用 `GET /public-ip/check`。
+
+## OpenAPI
+
+可使用下面的脚本重新导出当前 API 定义：
+
+```bash
+python scripts/export_openapi.py
+```
+
+导出结果会写入：
+
+- `openapi/openapi.json`
+- `openapi/openapi.yaml`
+
+## Docker Compose
+
+当前默认 Compose 服务名为 `app`，容器名固定为 `home-automation-app`。
+
+当前 Compose 分成两层：
+
+- `docker-compose.yml`：默认使用 registry image，适合部署 / 生产拉取
+- `docker-compose.override.yml`：仅为本地开发追加 `build: .`
+
+本地开发启动方式：
+
+```bash
+docker compose up -d --build
+```
+
+上面的命令会自动叠加 `docker-compose.override.yml`，因此本地仍然会按当前工作目录重新 build。
+
+如果要按生产方式直接从 registry 拉取并启动，显式只使用基础 compose 文件：
+
+```bash
+docker compose -f docker-compose.yml pull
+docker compose -f docker-compose.yml up -d
+```
+
+持续查看日志：
+
+```bash
+docker compose logs -f app
+```
+
+## Grafana Provisioning
+
+当前仓库支持通过 Grafana provisioning 自动加载 SQLite datasource 和 repo 内的 dashboard 导出文件。
+
+需要保留的文件路径如下：
+
+- `grafana/provisioning/datasources/locationrecorder.yaml`
+- `grafana/provisioning/datasources/poorecorder.yaml`
+- `grafana/provisioning/dashboards/provider.yaml`
+- `grafana/dashboards/locationrecorder.json`
+- `grafana/dashboards/poorecorder.json`
+
+这些文件的职责分别是：
+
+- `grafana/provisioning/datasources/locationrecorder.yaml`：声明 `locationrecorder` SQLite datasource，并指向 `/data/home-automation/locationRecorder.db`
+- `grafana/provisioning/datasources/poorecorder.yaml`：声明 `poorecorder` SQLite datasource，并指向 `/data/home-automation/pooRecorder.db`
+- `grafana/provisioning/dashboards/provider.yaml`：告诉 Grafana 从 `/var/lib/grafana/dashboards` 扫描并加载 dashboard JSON
+- `grafana/dashboards/locationrecorder.json`：location recorder dashboard 导出文件，内容本身不需要在 compose 中改写
+- `grafana/dashboards/poorecorder.json`：poo recorder dashboard 导出文件，内容本身不需要在 compose 中改写
+
+当前 `docker-compose.yml` 中，Grafana service 需要挂载以下目录：
+
+- `./grafana/provisioning -> /etc/grafana/provisioning:ro`
+- `./grafana/dashboards -> /var/lib/grafana/dashboards:ro`
+
+同时保留现有 named volume `homeautomation_grafana_storage:/var/lib/grafana` 作为 Grafana 运行态数据存储。
+
+一键启动前，至少需要以下文件已经存在：
+
+- `grafana/provisioning/datasources/locationrecorder.yaml`
+- `grafana/provisioning/datasources/poorecorder.yaml`
+- `grafana/provisioning/dashboards/provider.yaml`
+- `grafana/dashboards/locationrecorder.json`
+- `grafana/dashboards/poorecorder.json`
+
+启动方式：
+
+```bash
+docker compose up -d
+```
+
+启动后会发生的事情：
+
+- Grafana 容器会安装 `frser-sqlite-datasource` 插件
+- Grafana 会读取 `/etc/grafana/provisioning/datasources/` 下的 datasource YAML
+- Grafana 会读取 `/etc/grafana/provisioning/dashboards/provider.yaml`
+- Grafana 会从 `/var/lib/grafana/dashboards/` 自动导入两个 dashboard JSON
+- 现有 Grafana named volume 继续负责保存 Grafana 运行态数据，不会覆盖 repo 内的 dashboard 与 provisioning 文件
+
+## Container Image CI
+
+项目提供了一个 release image workflow：
+
+- workflow 文件：`.github/workflows/docker-image.yml`
+- 触发条件：push 匹配 `v*` 的 tag，例如 `v1.0.0`
+- registry：`code.wanderingbadger.dev`
+- image：`code.wanderingbadger.dev/<owner>/<repo>`
+
+`docker-compose.yml` 中生产默认使用的 app image 当前为：
+
+- `code.wanderingbadger.dev/tliu93/home-automation:latest`
+
+当前 workflow 不再把 image name 硬编码到特定 user package 路径，而是直接使用当前仓库标识生成镜像路径：
+
+- `code.wanderingbadger.dev/${github.repository}:${tag}`
+
+在 Gitea 这里，package 更贴近 repo 归属的语义，主要体现在镜像命名路径本身，而不是额外的“绑定”动作。也就是说，当前发布方式是按仓库路径约定来对齐 repo/package 语义。
+
+这个 workflow 会构建并推送 multi-arch image：
+
+- `linux/amd64`
+- `linux/arm64`
+
+推送的 tag：
+
+- release tag 本身，例如 `v1.0.0`
+- `latest`
+
+workflow 依赖以下 secrets：
+
+- `REGISTRY_USERNAME`
+- `REGISTRY_TOKEN`
+
+CI 产出的 image 是给部署机直接 `docker pull` 使用的。部署机不需要 checkout 本仓库，也不需要本地执行 `docker build`。
+
+## 运行测试
+
+```bash
+pytest
+```
+
+当前测试包含：
+
+- app 基本启动测试
+- `/status` endpoint 测试
+- 登录 / session 基础流程测试
+
+## OpenAPI 导出
+
+FastAPI 默认会暴露 OpenAPI。若需要导出静态 schema 文件，可运行：
+
+```bash
+python scripts/export_openapi.py
+```
+
+输出文件会写到：
+
+- `openapi/openapi.json`
+- `openapi/openapi.yaml`
+
+`openapi/` 当前纳入版本控制。接口发生变更时，应重新运行导出脚本并同步提交生成的 schema 文件。
+
+## 容器启动
+
+1. 准备环境变量文件
+
+```bash
+cp .env.example .env
+```
+
+2. 启动容器
+
+```bash
+docker compose up --build
+```
+
+默认端口：
+
+- `8000:8000`
+
+SQLite 持久化目录：
+
+- 本地 `./data`
+- 容器内 `/app/data`

+# Python 骨架架构概览
+
+本文档说明当前 Python skeleton 的职责边界与目录组织。它描述的是“后续迁移承载体”，不是完整业务实现。
+
+## 当前目标
+
+这一轮的目标是提供一个稳定、轻量、可持续扩展的基础工程，使后续可以逐步迁移：
+
+- TickTick integration
+- Home Assistant integration
+- poo records
+- location / life trajectory
+
+## 目录设计
+
+### `app/`
+
+应用核心代码目录。
+
+- `main.py`
+  - FastAPI app factory
+  - lifespan
+  - 基础路由注册
+- `config.py`
+  - 环境变量驱动的 settings
+- `auth_db.py`
+  - app 级共享 auth 数据库
+- `db.py`
+  - SQLAlchemy engine / session / Base
+- `dependencies.py`
+  - 通用依赖注入
+- `api/`
+  - HTTP routes
+  - 当前已迁入 `/login`、`/logout`、`/admin`
+  - 当前已迁入 `GET /public-ip/check`
+  - 当前已迁入 `POST /homeassistant/publish` 第一版入口
+  - 当前已迁入 `POST /poo/record` 与 `GET /poo/latest`
+- `models/`
+  - SQLAlchemy models
+  - 当前 `auth`、`location` 与 `poo` 使用各自独立的数据库 base
+- `schemas/`
+  - Pydantic schemas
+- `services/`
+  - 业务服务层
+  - 当前已迁入 config page 的 DB 持久化逻辑
+  - 当前已迁入 public IPv4 检查、状态持久化与变化通知逻辑
+  - 当前已迁入 SMTP 发信与测试发信逻辑
+- `integrations/`
+  - 外部系统适配层
+  - 当前已迁入 Home Assistant outbound adapter
+- `templates/`
+  - Jinja2 模板
+- `static/`
+  - 极简静态资源
+
+### `alembic_location/`
+
+Location DB 的 migration 基础设施。
+
+### `alembic_app/`
+
+App DB 的 migration 基础设施。
+
+### `alembic_poo/`
+
+Poo DB 的 migration 基础设施。
+
+### `tests/`
+
+pytest 测试目录。后续可以在这里自然扩展：
+
+- unit tests
+- mock tests
+- integration tests
+
+### `scripts/`
+
+辅助脚本目录。当前包含 OpenAPI 导出脚本。
+
+## 当前约束
+
+- 当前只搭骨架，不迁业务逻辑
+- 当前数据库继续使用 SQLite
+- 当前不引入前后端分离
+- 当前不设计 Notion 模块
+- 当前通知能力仍保持极小范围，不引入独立通知中心或多渠道抽象
+
+## 关于 Notion
+
+Notion 在 Go 版本中仍是现状模块，但在 Python 重构中已经明确属于 removed scope。
+
+因此当前 Python skeleton：
+
+- 不提供 Notion integration 模块
+- 不提供 Notion schema
+- 不预留 Notion 相关业务流
+
+如果未来需要回顾其历史作用，应继续参考 Go 版本和现有迁移盘点文档，而不是在 Python 骨架中保留它。

+# 基础鉴权说明
+
+本文档说明当前 Python 重构项目里已经落地的第一版鉴权基座。
+
+这一轮只解决：
+
+- 登录页
+- 登录 / 登出流程
+- server-side session
+- 一个最小受保护页面
+
+这一轮明确不解决：
+
+- 完整 config persistence
+- 完整 config CRUD
+- 多用户权限系统
+- OAuth / SSO / RBAC
+
+## 当前 auth 模型
+
+- 认证方式：`username/password`
+- 会话方式：server-side session
+- 客户端凭据：session cookie
+- 页面形态：Jinja server-side template
+
+## 当前持久化
+
+当前新增一个共享 App DB：
+
+- `APP_DATABASE_URL`
+- 默认值：`sqlite:///./data/app.db`
+
+当前 auth 相关数据存放在这个 DB 中：
+
+- `auth_users`
+- `auth_sessions`
+- `app_config`
+
+当前没有把 auth 数据和 `location` / `poo` DB 混放。
+
+当前这部分现在也走 Alembic 管理：
+
+- Alembic 环境：`alembic_app.ini` + `alembic_app/`
+- 初始化脚本：`python scripts/app_db_adopt.py`
+
+当前没有 legacy app DB，所以这一版脚本只负责初始化新库，不负责 legacy adoption。
+
+`app_config` 现在承接运行时配置持久化。
+
+其中：
+
+- `.env` 负责 bootstrap / fallback
+- `app_config` 表负责运行时配置覆盖
+- 登录密码仍然属于认证数据，使用 Argon2 哈希，不存进 `app_config`
+
+## 首次启动与 bootstrap
+
+如果 auth DB 中还没有任何用户，应用启动时会要求：
+
+- `AUTH_BOOTSTRAP_USERNAME`
+- `AUTH_BOOTSTRAP_PASSWORD`
+
+并创建首个 admin 用户。
+
+当前默认 bootstrap 值就是：
+
+- username: `admin`
+- password: `admin`
+
+首次登录后，系统会强制要求修改密码。
+
+如果你希望在首次启动前就覆盖默认值，可以直接设置环境变量：
+
+- `AUTH_BOOTSTRAP_USERNAME`
+- `AUTH_BOOTSTRAP_PASSWORD`
+
+建议流程是：
+
+1. 配好 `.env`
+2. 运行 `python scripts/app_db_adopt.py`
+3. 启动应用
+4. 用 `admin / admin` 首次登录
+5. 立即修改密码
+
+## 安全设计
+
+当前这版已经落实的基础安全点：
+
+- 密码不明文存储，使用 Argon2 哈希
+- session cookie 为 `HttpOnly`
+- cookie 使用 `SameSite=Lax`
+- `Secure` cookie 在非 `development` 环境默认开启
+- 登录表单与登出表单都有基础 CSRF 校验
+- session token 为随机生成，服务端只持久化 token hash
+- session 有过期时间与显式失效机制
+
+## 当前受保护范围
+
+当前这轮只保护了页面入口：
+
+- `GET /config`
+- `POST /config`
+- `POST /config/change-password`
+- `POST /logout`
+
+相关流程：
+
+- `GET /login`
+- `POST /login`
+
+未登录访问 `/config` 时会被重定向到 `/login`。
+
+## 下一步不在本轮内
+
+后续可以在这个基座上继续做：
+
+- 配置页面接入
+- config persistence
+- 更细的受保护路由范围
+- 用户初始化 / 密码轮换的更正式 runbook

+
+## 当前已支持的 Target / Action
+
+当前已接回的路径：
+
+- `location_recorder / record`
+- `ticktick / create_action_task`
+
+其中：
+
+- `location_recorder / record` 会把 `content` 解析为 location recorder 请求，并直接走当前 Python 项目里的 location 写入逻辑
+- `ticktick / create_action_task` 会沿用 legacy 行为，把 `content` 解析为：
+  - `action: string`
+  - `due_hour: int`
+  - 可选 `title` 字段会被忽略
+- TickTick task title 仍使用 `action`
+- due date 仍按 legacy 语义计算：先取 `now + due_hour`，再落到该日期的“次日零点”，最后转成 UTC 后写给 TickTick
+- 具体 project 仍由 `HOME_ASSISTANT_ACTION_TASK_PROJECT_ID` 提供
+
+## 当前尚未接回

+
+- `/homeassistant/publish`
+- Home Assistant inbound command gateway
+- Home Assistant 驱动当前 app 的入站消息路由
+
+## 当前已支持能力

+
+- 发布 / 更新 sensor state
+  - `POST /api/states/{entity_id}`
+- 触发 Home Assistant webhook
+  - `POST /api/webhook/{webhook_id}`
+
+这两项能力是按 legacy Go 中 `util/homeassistantutil/homeassistantutil.go` 的出站行为迁入的。
+
+## 当前配置
+
+当前 outbound adapter 依赖以下配置：
+
+- `HOME_ASSISTANT_BASE_URL`
+- `HOME_ASSISTANT_AUTH_TOKEN`
+- `HOME_ASSISTANT_TIMEOUT_SECONDS`
+
+如果缺少必要配置，client 会直接抛出配置错误，而不是静默跳过。
+
+## 错误处理策略
+
+当前策略保持保守和简单：
+
+- 配置缺失：抛出 `HomeAssistantConfigError`
+- 参数明显非法：抛出 `ValueError`
+- Home Assistant 返回非 200/201：抛出 `HomeAssistantRequestError`
+- 网络请求失败：抛出 `HomeAssistantRequestError`
+
+当前还没有做：

+- 自动重试
+- 熔断
+- 更复杂的 backoff 策略

+# Location Recorder
+
+本文档说明 `location recorder` 在 Python 项目中的当前数据库接管策略，以及 legacy SQLite 接管 runbook。
+
+当前 Python 版本的 `POST /location/record` 请求校验策略是：
+
+- `latitude` 和 `longitude` 为必填，缺失或无法解析成合法数值时返回 `400 bad request`
+- `altitude` 为可选，缺失或非法时按 `0` 处理
+- unknown field 仍返回 `400 bad request`
+- 对 caller 的错误响应保持简洁，不直接暴露底层校验细节；详细原因只写日志
+
+## Legacy 事实基线
+
+当前 legacy SQLite 中 `location` 表的真实 schema 为：
+
+```sql
+CREATE TABLE location (
+  person TEXT NOT NULL,
+  datetime TEXT NOT NULL,
+  latitude REAL NOT NULL,
+  longitude REAL NOT NULL,
+  altitude REAL,
+  PRIMARY KEY (person, datetime)
+);
+```
+
+历史上 legacy Go 实现使用：
+
+```sql
+PRAGMA user_version = 2;
+```
+
+这代表旧系统曾依赖 `user_version` 管理 location 数据库版本，但这不再是 Python 项目的长期 migration 机制。
+
+## 当前策略
+
+当前采用的最小必要接管方案是：
+
+1. 把上述 `location` schema 视为 Alembic baseline
+2. 新数据库通过 Alembic `upgrade head` 初始化
+3. 已有 legacy SQLite 数据库，只要确认 schema 与 baseline 一致，再通过 `alembic stamp` 接管
+4. 如果数据库已经存在 `alembic_version`，则必须先确认当前 revision 与项目预期 baseline 一致
+5. 只有 revision 一致时，才视为该库已经被正确接管
+6. 未来不再以 `PRAGMA user_version` 作为主 migration 机制
+
+当前 baseline revision 是：
+
+- `20260419_01_location_baseline`
+
+当前提供的最小脚本入口是：
+
+```bash
+python scripts/location_db_adopt.py
+```
+
+如果你更喜欢模块方式运行，也可以用：
+
+```bash
+python -m scripts.location_db_adopt
+```
+
+它只针对 `LOCATION_DATABASE_URL` 工作，并且遵守保守接管原则：
+
+- 本地已有 DB 文件：先校验，再接管
+- 本地没有 DB 文件：按新库初始化
+- 任一校验不通过：立即报错并停止
+
+应用本身在启动时不会自动替你初始化 `location` 数据库。
+应用启动时会对 `LOCATION_DATABASE_URL` 做只读校验：
+
+- 文件不存在：直接报错，并提示先运行接管脚本
+- 文件存在但还没有 `alembic_version`：直接报错，要求先完成 legacy 接管
+- 文件已被 Alembic 管理但 revision 不匹配：直接报错并拒绝启动
+
+这是有意为之，用来避免应用在错误路径上静默创建新库，或带着错误数据库版本继续跑业务。
+
+## 新数据库初始化
+
+如果本地不存在 `LOCATION_DATABASE_URL` 指向的 DB 文件：
+
+- 脚本会先创建父目录
+- 然后执行 Alembic `upgrade head`
+- 最终建立 `location` 表与 `alembic_version` 表
+
+手工执行时也等价于：
+
+```bash
+alembic upgrade head
+```
+
+这会创建与 legacy 相同的 `location` 表结构，并在库中建立 Alembic revision 记录。
+
+## 旧数据库接管
+
+对于已经存在的 legacy SQLite 数据库：
+
+1. 先确认 DB 文件存在
+2. 如果已经存在 `alembic_version` 表，则先读取当前 revision
+3. 如果 revision 等于 `20260419_01_location_baseline`，则视为该库已经被 Alembic 正确接管
+4. 如果 revision 不匹配，立即报错并停止，不做任何自动修复
+5. 如果还没有 `alembic_version` 表，则读取当前 DB 中 `location` 表的实际 schema
+6. 与 baseline schema 做严格比对
+7. 再检查 `PRAGMA user_version`
+8. 只有 schema 匹配且 `user_version = 2` 时，才执行 Alembic `stamp`
+9. 接管完成后，后续 migration 才交给 Alembic 管理
+
+示例：
+
+```bash
+LOCATION_DATABASE_URL=sqlite:///./data/locationRecorder.db alembic stamp 20260419_01_location_baseline
+```
+
+或直接执行脚本：
+
+```bash
+LOCATION_DATABASE_URL=sqlite:///./data/locationRecorder.db python scripts/location_db_adopt.py
+```
+
+这样做的含义是：
+
+- 告诉 Alembic：这个数据库已经处于 baseline 结构
+- 不修改已有 `location` 表数据
+- 后续 migration 由 Alembic 接管
+
+## Fail Closed 原则
+
+当前策略是保守接管，不做未知 legacy 状态的自动修复。
+
+如果出现以下任一情况，脚本会直接报错并停止：
+
+- 找不到 `location` 表
+- `location` 表 schema 与 baseline 不一致
+- `PRAGMA user_version` 不等于 `2`
+- 已有 `alembic_version`，但 revision 与预期 baseline 不一致
+- 目标 DB 不是 SQLite URL
+
+当前不会尝试：
+
+- 自动修表
+- 自动调整 `user_version`
+- 自动推断未知 legacy 状态
+
+如果发生这些情况，应先人工确认数据库状态，再决定是否需要单独迁移或修复。
+
+## 关于 `data/locationRecorder.db`
+
+你本地放在 `data/locationRecorder.db` 的 legacy 样本库，可以用于：
+
+- 人工核对 schema
+- 手动验证 `stamp` 接管流程
+- 做开发时的兼容性确认
+
+但当前代码不应硬依赖这个文件存在。
+
+## 测试样本的安全使用方式
+
+如果要用 legacy SQLite 样本做测试或验证，应遵守：
+
+1. 不直接在原始样本文件上跑测试
+2. 先复制到临时路径
+3. 所有 `stamp`、写入、实验性 migration 都只针对副本执行
+
+自动化测试里当前采用的方式是：
+
+- 构造一个“legacy 风格”的临时 SQLite 文件
+- 建出同样的 `location` 表
+- 设置 `PRAGMA user_version = 2`
+- 再执行接管脚本中的 adopt 逻辑
+
+同时也覆盖：
+
+- DB 文件不存在时的新库初始化路径
+- schema 不匹配时的失败路径
+- `user_version` 不匹配时的失败路径
+
+这样可以验证接管路径，同时不污染真实样本库。

+# Poo Recorder

+## 当前基线

+当前生产版本中的真实 SQLite schema 为：
+
+```sql
+CREATE TABLE poo_records (
+  timestamp TEXT NOT NULL,
+  status TEXT NOT NULL,
+  latitude REAL NOT NULL,
+  longitude REAL NOT NULL,
+  PRIMARY KEY (timestamp)
+);
+```
+
+历史上 legacy Go 实现使用：
+
+```sql
+PRAGMA user_version = 1;
+```
+
+当前 Python 迁移以这套 schema 为事实基线，不重新设计表结构。
+
+## 当前已迁入的 API
+
+当前 Python 项目已经接入：
+
+- `POST /poo/record`
+- `GET /poo/latest`
+
+### `POST /poo/record`
+
+用途：
+
+- 记录一条 poo event
+- 最佳努力地刷新 Home Assistant sensor
+- 如果配置了 `POO_WEBHOOK_ID`，最佳努力地触发 Home Assistant webhook
+
+请求体：
+
+```json
+{
+  "status": "done",
+  "latitude": "1.23",
+  "longitude": "4.56"
+}
+```
+
+当前策略：
+
+- unknown field：`400 bad request`
+- 数值非法：`400 bad request`
+- 记录成功后，即使 Home Assistant side effect 失败，也不会回滚本地 DB 写入
+
+### `GET /poo/latest`
+
+用途：
+
+- 读取最新一条 poo 记录
+- 将其重新发布到 Home Assistant sensor
+
+当前外部行为与 legacy 保持一致：
+
+- 成功：空响应体，HTTP 200
+- 如果当前 DB 里还没有任何 poo 记录：仍返回空响应体，HTTP 200，但不会发布 sensor
+- 真正的发布失败：简洁 `internal server error`
+
+## Home Assistant side effects
+
+当前已复用 Python 项目中已有的 Home Assistant outbound adapter。
+
+当前支持：
+
+- 发布 / 更新 poo status sensor
+- 可选触发 webhook
+
+相关配置：
+
+- `HOME_ASSISTANT_BASE_URL`
+- `HOME_ASSISTANT_AUTH_TOKEN`
+- `HOME_ASSISTANT_TIMEOUT_SECONDS`
+- `POO_SENSOR_ENTITY_NAME`
+- `POO_SENSOR_FRIENDLY_NAME`
+- `POO_WEBHOOK_ID`
+
+## Alembic 接管策略
+
+poo 的接管逻辑刻意保持与 location 一致。
+
+当前 baseline revision：
+
+- `20260420_01_poo_baseline`
+
+当前提供的脚本入口：
+
+```bash
+python scripts/poo_db_adopt.py
+```
+
+或：
+
+```bash
+python -m scripts.poo_db_adopt
+```
+
+规则如下：
+
+1. 如果本地不存在 poo DB 文件：
+   - 视为新库初始化
+   - 通过 `alembic_poo upgrade head` 创建新库
+2. 如果本地已经存在 legacy DB：
+   - 先检查 `poo_records` 表 schema
+   - 再检查 `PRAGMA user_version = 1`
+   - 只有完全匹配，才通过 Alembic `stamp` 接管
+3. 如果 schema 或 `user_version` 不匹配：
+   - 直接失败
+   - 不自动修复
+4. 如果数据库已经存在 `alembic_version`：
+   - 只有 revision 与当前 baseline 一致才接受
+   - 否则直接失败
+
+同时，应用启动时也会对 `POO_DATABASE_URL` 做只读校验：
+
+- 文件不存在：拒绝启动
+- DB 尚未被 Alembic 接管：拒绝启动
+- revision 不匹配：拒绝启动
+
+## 明确移除 Notion
+
+这一轮不会迁入任何 Notion 逻辑。
+
+也就是说，当前 Python 版的 poo recorder：
+
+- 不保留 Notion adapter
+- 不保留 Notion sync
+- 不保留 `tableId` 依赖
+- 不因为 legacy 中存在 Notion 就继续保留兼容层

+# 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。

+- `HOME_ASSISTANT_ACTION_TASK_PROJECT_ID`
+
+## 兼容性说明
+
+- 仍保留 legacy 的 OAuth authorization code flow
+- OAuth callback URI 现在由 `APP_HOSTNAME` 和当前环境自动推导：`development` 使用 `http`，其他环境使用 `https`
+- `state` 仍是进程内临时状态；如果服务在 start 和 callback 之间重启，本轮实现下授权需要重新开始
+- 不再把 token 写回 `.env` 或其他配置文件，统一写入 config 表
+- 当前没有引入 legacy 的第三方 TickTick 库，先用标准库完成兼容行为
+
+## 后续适合单独拆分的工作
+
+- 给 config 页面增加明确的 TickTick 授权入口
+- 增加 project 探测或选择能力，减少手工填写 `HOME_ASSISTANT_ACTION_TASK_PROJECT_ID`
+- 如果后续发现 OAuth/token 生命周期需要更强健，再补 refresh token 或持久化 auth state
