+### Definition of Done (每次编码完成的硬门禁) — 不通过不算完成
+
+每一次代码改动（无论多小）在声明「完成」前，**必须**按顺序全部通过以下门禁。任一项失败就回去修，不得跳过、不得只跑部分、不得仅靠肉眼判断。
+
+1. **TDD 已遵守** — 先写失败测试（RED）→ 实现到通过（GREEN）→ 重构（REFACTOR）。新增/修改的逻辑都有对应测试；改 bug 先写能复现的失败测试。见上文 §TDD。
+2. **测试覆盖率 ≥ 80%（已工具化 + CI 强制）** — 改动涉及的模块覆盖率不得低于 80%；新代码不许拉低整体覆盖率。跑命令核对真实数字，不要估：
+   - 后端：`uv run pytest -q --cov --cov-report=term-missing --cov-fail-under=80`（低于 80% 直接非零退出。当前基线 ~88%）。配置在根 `pyproject.toml` 的 `[tool.coverage.*]`。
+   - 前端：`cd apps/web && pnpm test:coverage`（`vitest.config.ts` 设 lines/functions/branches/statements 阈值 80。当前基线 ~95%）。
+   - **前端覆盖率范围 = `lib/**`（纯逻辑 + React hooks）**：hooks(`use*.ts`)用 jsdom + `@testing-library/react` 的 `renderHook` 单测（测试文件首行 `// @vitest-environment jsdom`，mock `@/lib/api/client` + `@/components/Toast`，参见 `lib/generation/useWorldGen.test.ts`）。组件(.tsx)仍由 E2E/人工验收覆盖，不在 vitest 范围（写新 hook 时必须同步补 `renderHook` 测试）。
+3. **跑完三类自动化测试**（改动触及的那侧必跑，跨栈改动两侧都跑）：
+   - **后端 Unit + Integration**：`uv run pytest -q`（需要 pg 的集成测试先 `docker compose up -d pg`）。
+   - **前端自动化测试**：`cd apps/web && pnpm test`（vitest）。
+   - **E2E**（动到 write→review→accept 主链路时）：跑相关 E2E 流程（mock gateway）。
+   - LLM 一律 mock，**绝不在测试/CI 命中真实 LLAPI**（见上文 §TDD）。
+4. **全部门禁绿**（与 §Toolchain、CI 一致）：
+   - 后端：`uv run ruff check .` · `uv run ruff format .` · `uv run mypy packages apps` · `uv run pytest -q` · 动过模型时 `uv run alembic check` 无漂移。
+   - 前端：`cd apps/web && pnpm lint` · `pnpm typecheck` · `pnpm test` · `pnpm build`；动过后端 schema 先 `pnpm gen:api` 再校验。
+5. **符合架构与编程规范** — 不违反上文 §Architectural invariants、§Locked tech stack、§Python/§Frontend/§LangGraph 实践，以及全局编码风格（不可变更新、KISS/DRY/YAGNI、文件 <800 行、函数 <50 行、显式错误处理、边界校验、无硬编码密钥）。安全敏感改动（auth/输入处理/DB 查询/外部 API/加密）按 §code-review 触发安全自查。
+6. **提交（每次完成都 commit）** — 见下文 §Commit discipline。
+7. **回写状态/文档** — 按 §Per-task workflow 更新 `PROGRESS.md`；若实现暴露 spec 缺口，回写对应 spec（见 §Conventions）。
+
+> 报告要诚实：测试失败就如实说明并贴输出；跳过了哪一步要讲明；只有真正跑过且全绿，才说「完成」。
+
+### Commit discipline (提交纪律) — 每次完成即提交
+
+- **每次完成一个可工作的改动就 commit**，小步提交、一次一个聚焦改动；不要把多个无关改动堆进一个提交。
+- **提交前** Definition of Done 的门禁（1–5）必须已全绿——不提交跑不过测试或 lint/类型不干净的代码。
+- **提交信息格式**：遵循 Conventional Commits —— `<type>: <description>`（type ∈ feat/fix/refactor/docs/test/chore/perf/ci），中文描述与本仓库现有提交风格一致；需要时附 body 说明「为什么」。
+- **提交信息禁止任何署名/归属尾注** — **不得包含 `Co-Authored-By:` 或任何 `Generated with` / AI 署名行**（全局已在 `~/.claude/settings.json` 关闭 attribution；此处再次明确，覆盖任何默认加尾注的行为）。
+- **分支**：不在 `main` 上直接提交；按 §Git Workflow 在特性分支工作。`develop` 为当前集成分支。
+- **push / 开 PR 仅在用户明确要求时**进行；PR body 同样不加 AI 署名。
+
 ## Toolchain (Phase 0 已落地)
 
 工具：**uv**(Python workspace，4 members: `apps/api` + `packages/{shared,config,db}`) + **pnpm**(前端，`apps/web`)。Python 3.12+，Node 22。
 
 - **环境变量**：`uv` 装到 `~/.local/bin`，命令前 `export PATH="$HOME/.local/bin:$PATH"`。
 - **依赖安装**：`uv sync`（后端，仓库根）；`pnpm install`（前端，`cd apps/web`）。
-- **本地起服务**：`docker compose up`（pg + api + web）。仅起库：`docker compose up -d pg`。裸跑 API：`uv run uvicorn ww_api.main:app --reload`。
+- **本地起服务（宿主端口 +1000 防冲突：web 4000 / api 9000 / pg 6432；容器内仍 3000/8000/5432）**：`docker compose up`（pg + api + web，端口已 +1000）。仅起库：`docker compose up -d pg`（宿主 6432）。裸跑：API `uv run uvicorn ww_api.main:app --port 9000 --reload`（读根 `.env`→pg 6432 / CORS 放行 4000）；前端 `cd apps/web && pnpm dev`（`next dev -p 4000`，读 `apps/web/.env.local`→`NEXT_PUBLIC_API_BASE=http://localhost:9000`）。`.env`/`.env.local` 为本机文件（gitignored）。
 - **迁移**：`uv run alembic upgrade head`；改模型后 `uv run alembic revision --autogenerate -m "..."`；漂移校验 `uv run alembic check`（需 pg 在跑）。
-- **后端门禁**：`uv run ruff check .` · `uv run ruff format .` · `uv run mypy packages apps` · `uv run pytest -q`。单测：`uv run pytest path::test -q`。
+- **后端门禁**：`uv run ruff check .` · `uv run ruff format .` · `uv run mypy packages apps` · `uv run pytest -q`。覆盖率门禁：`uv run pytest -q --cov --cov-report=term-missing --cov-fail-under=80`。单测：`uv run pytest path::test -q`（单测不带 `--cov`，避免 fail-under 误报）。
-- **前端门禁**（`cd apps/web`）：`pnpm lint` · `pnpm typecheck` · `pnpm test`（vitest）· `pnpm build`。
+- **前端门禁**（`cd apps/web`）：`pnpm lint` · `pnpm typecheck` · `pnpm test`（vitest）· `pnpm build`。覆盖率门禁：`pnpm test:coverage`（阈值 80%，范围 `lib/**`）。
 - **重生成 TS 客户端**：改后端 schema 后 `cd apps/web && pnpm gen:api`（离线：`uv run python -m ww_api.export_openapi` → `openapi-typescript` 生成 `lib/api/schema.d.ts`）。
 - **pnpm 配置**：在 `apps/web/pnpm-workspace.yaml`（pnpm 11 不再读 package.json/.npmrc）——含 `onlyBuiltDependencies` 白名单 + `verifyDepsBeforeRun: false`（见 `memory/gotchas.md`）。
 - **CI**：`.github/workflows/ci.yml`（backend job 带 pg service 跑 ruff/mypy/alembic/pytest；frontend job 跑 gen:api/lint/typecheck/test）。

+
+> 本文是把「AI 辅助中文网文写作工作流」部署到服务器的实操指南。
+> 所有命令/端口/服务名均以仓库当前 `docker-compose.yml`、两份 `Dockerfile`、
+> `.env.example`、`packages/config/ww_config/settings.py`、`apps/api/ww_api/main.py`
+> 为准。**遇到与你手上 compose 不一致处，一律以实际 `docker-compose.yml` 为准。**
+>
+> ⚠️ **重要前提：本产品当前是「单用户原型」，没有任何认证 / 多租户**（`users`/`owner_id`
+> 是桩）。这直接决定了安全部署的红线——见 [§6 安全红线](#6-安全红线单用户原型的硬约束)。
+> **不要在没有网络层保护的情况下把它裸暴露到公网。**
+
+---
+
+## 1. 架构与前置条件
+
+### 1.1 三个组件
+
+部署单元由三个容器组成（服务名即 `docker-compose.yml` 中的 key）：
+
+| 服务名 | 角色 | 镜像来源 | 容器端口 | compose 发布端口 | 健康检查 |
+|---|---|---|---|---|---|
+| `pg` | Postgres 16 数据库（唯一真源） | `postgres:16-alpine`（拉取） | 5432 | `5432:5432` | ✅ `pg_isready -U writer`（interval 5s / timeout 3s / retries 10） |
+| `api` | FastAPI 后端（async + SSE + LangGraph 编排） | 由 `apps/api/Dockerfile` 构建，构建上下文 = **仓库根 `.`** | 8000 | `8000:8000` | ✅ Dockerfile `HEALTHCHECK`：`python urllib` 打 `/health`（interval 30s / timeout 5s / start-period 20s / retries 3） |
+| `web` | Next.js 前端（standalone 产物） | 由 `apps/web/Dockerfile` 构建，构建上下文 = **`./apps/web`** | 3000 | `3000:3000` | ✅ Dockerfile `HEALTHCHECK`：`node http` 打 `/`（interval 30s / timeout 5s / start-period 20s / retries 3） |
+
+依赖关系（compose `depends_on`）：
+- `api` 依赖 `pg`，且**等 pg 健康**后才起（`condition: service_healthy`）。
+- `web` 依赖 `api`，但**只是启动顺序**（无 `condition`）——web 可能先于 api 就绪，属可容忍的运行期竞态。
+
+数据持久化：命名卷 `pgdata` 挂到 `pg` 的 `/var/lib/postgresql/data`。**备份/迁移数据 = 备份这个卷**（见 §7）。
+
+### 1.2 镜像怎么来
+
+两个应用镜像都从源码 `Dockerfile` **本地构建**（仓库未发布预构建镜像）：
+
+- **`apps/api/Dockerfile`**：`python:3.12-slim` + 从 `ghcr.io/astral-sh/uv` 拷入 `uv`；`COPY pyproject.toml uv.lock* / packages / apps/api`；`uv sync --no-dev --frozen`（失败回退非 frozen）；`CMD uv run uvicorn ww_api.main:app --host 0.0.0.0 --port 8000`。
+- **`apps/web/Dockerfile`**：多阶段。build 阶段 `node:22-slim` + corepack(pnpm)，`pnpm install --frozen-lockfile` → `pnpm build`（Next `output: "standalone"`，见 `apps/web/next.config.mjs`）；run 阶段只拷 `.next/standalone` + `.next/static` + `public`，`CMD node server.js`。
+
+> web 镜像在构建期消费**已提交的** OpenAPI TS 客户端 `apps/web/lib/api/schema.d.ts`（该文件在 git 里，仅 `openapi.json` 被 gitignore）。因此 web 构建**不需要**联网跑 `pnpm gen:api`。**但**：后端 schema 改动后，必须先 `cd apps/web && pnpm gen:api` 重生成并提交 `schema.d.ts`，再构建 web 镜像，否则前后端契约漂移。
+
+### 1.3 需要的环境变量（逐项）
+
+变量来源 = `packages/config/ww_config/settings.py`（后端）+ `apps/web/lib/api/config.ts`（前端）。
+
+**后端（api 容器）：**
+
+| 变量 | 是否必填 | 默认值 | 说明 |
+|---|---|---|---|
+| `DATABASE_URL` | 建议显式设 | `postgresql+asyncpg://writer:writer@localhost:5432/writer` | **异步**连接串（asyncpg）。运行时 + `alembic upgrade head` 都读它（`packages/db/migrations/env.py` 用它建 async engine 跑迁移）。容器内主机名用 compose 服务名 `pg`。 |
+| `DATABASE_URL_SYNC` | 建议显式设 | `postgresql+psycopg://writer:writer@localhost:5432/writer` | **同步**连接串（psycopg）。`.env.example` 与 compose 均定义；供同步工具链使用。 |
+| `APP_ENV` | 否 | `dev` | 环境名。生产设 `prod`。 |
+| `LOG_JSON` | 否 | `false` | 结构化日志是否输出 JSON。**生产设 `true`**（structlog JSON，便于采集）。 |
+| `CREDENTIAL_ENC_KEY` | **✅ 必填** | 空（`SecretStr("")`） | provider 凭据对称加密密钥（Fernet, urlsafe-base64 32B）。**api 启动即校验**（`main._lifespan` 调 `_fernet(...)`）：缺失/非法 → **进程直接启动失败**，不带病接流量。生产**必须**用新密钥，见 §2.3。 |
+| `CORS_ORIGINS` | 生产强烈建议 | `["http://localhost:3000","http://127.0.0.1:3000"]` | 浏览器跨源白名单，逗号分隔覆盖。**启动断言不含通配 `*`**（与 `allow_credentials=True` 不兼容，`main.create_app` 里 `assert "*" not in cors_origins`）。生产填前端真实来源，如 `https://writer.example.com`。 |
+
+**前端（web 容器）：**
+
+| 变量 | 是否必填 | 默认值（`config.ts` 回退） | 说明 |
+|---|---|---|---|
+| `NEXT_PUBLIC_API_BASE` | 生产建议 | `http://localhost:8000` | **浏览器端**访问 API 的基址。⚠️ Next.js 的 `NEXT_PUBLIC_*` 在**构建期内联**进客户端 bundle——只在运行期设它**不会改**已构建产物。web `Dockerfile` 现声明 `ARG NEXT_PUBLIC_API_BASE`（默认 `http://localhost:8000`），base/prod compose 的 `web.build.args` 均传入它；生产在**构建期**用 `docker compose build` 注入前端可达的公网 API 地址（通常反代后的 `https://writer.example.com` 之类）。 |
+| `API_BASE_INTERNAL` | 容器编排建议 | 回退到 `NEXT_PUBLIC_API_BASE` | **服务端组件(RSC)**取数用的内网基址。base/prod compose 的 `web.environment` 已设为 `http://api:8000`（compose 服务名），RSC 直连 api 容器。 |
+
+### 1.4 LLM provider key 不进环境变量
+
+**不要**把任何 LLM 供应商密钥（DeepSeek/Kimi/OpenAI/Anthropic/Qwen/GLM/Gemini 等）写进 env 或 compose。
+本产品的 provider 凭据是**部署后在应用「设置」页录入**，由后端用 `CREDENTIAL_ENC_KEY`（Fernet）
+**加密后存进 Postgres**（`provider_credentials` 表 / `settings_providers` 路由）。
+Kimi Code 走 OAuth 订阅授权（`kimi_oauth` 路由），同样落库。
+
+推论：`CREDENTIAL_ENC_KEY` 是解开所有已存凭据的唯一钥匙——**丢了它 = 库里所有 provider 凭据不可解密**，只能重新录入。务必备份保管（见 §2.3 / §6）。
+
+### 1.5 部署面缺口——已修复（现可照抄部署）
+
+此前审阅 Dockerfile/compose 发现的 6 个「照抄即部署」缺口**均已在部署面文件消除**（不改应用源码）。现状如下：
+
+1. **api 镜像已拷 `alembic.ini`** ✅：`apps/api/Dockerfile` 在 `COPY apps/api` 之后新增 `COPY alembic.ini ./`（迁移目录 `packages/db/migrations` 随 `COPY packages` 进镜像）。因此可直接在 api 容器内跑 `docker compose run --rm api uv run alembic upgrade head`（§2.4）。
+2. **compose `api` 已提供 `CREDENTIAL_ENC_KEY`** ✅：base `docker-compose.yml` 的 `api.environment` 现注入 `CREDENTIAL_ENC_KEY`（`${CREDENTIAL_ENC_KEY:-<dev 占位>}`，compose 自动读仓库根 `.env` 覆盖该默认）、`APP_ENV`/`LOG_JSON`/`CORS_ORIGINS`。**base compose 现可直接 `up` 起 api**（无 `.env` 也走 dev 占位 key 起来；生产用 §2.2 覆盖文件强制真值）。
+3. **compose `web` 已设 `API_BASE_INTERNAL`** ✅：base 的 `web.environment` 设 `API_BASE_INTERNAL=http://api:8000`，RSC 服务端取数直连 api 容器。
+4. **`NEXT_PUBLIC_API_BASE` 支持构建期注入** ✅：web `Dockerfile` 在 `pnpm build` 前声明 `ARG NEXT_PUBLIC_API_BASE=http://localhost:8000` + `ENV`；base/prod compose 的 `web.build.args` 传入它。生产 `docker compose -f ... -f docker-compose.prod.yml build` 即把公网 API 基址内联进 bundle。
+5. **api/web 已内置 HEALTHCHECK** ✅：`apps/api/Dockerfile` 用 stdlib `urllib` 打 `/health`、`apps/web/Dockerfile` 用 `node http` 打 `/`（均 interval 30s / timeout 5s / start-period 20s / retries 3，镜像无 curl 故用运行时自带解释器）。编排/反代可直接读容器健康态。
+6. **base 弱口令/裸暴露——生产用覆盖层加固** ✅：base `docker-compose.yml` 保持 dev 便利（pg `writer/writer`、`5432:5432`、`APP_ENV=dev`）；新增 **`docker-compose.prod.yml`** 覆盖层做生产加固——pg 强口令 `${POSTGRES_PASSWORD}`（`:?` 缺失即拒起）、pg 仅绑 `127.0.0.1:5432`、`APP_ENV=prod`、`LOG_JSON=true`、`CREDENTIAL_ENC_KEY`/`DATABASE_URL*`/`CORS_ORIGINS`/`NEXT_PUBLIC_API_BASE` 全从 env 且必填、`restart: unless-stopped`。
+
+> 构建面同时补了两个 `.dockerignore`（仓库根 + `apps/web`）：排除宿主 `node_modules`/`.next`/`.venv`/`.git`/缓存，避免宿主平台原生二进制（如 macOS 的 next-swc）经 `COPY . .` 覆盖容器内 Linux 版导致 `pnpm build` 失败，并加速构建上下文传输、保证可复现。
+>
+> 校验：`docker compose config`（base）与 `docker compose -f docker-compose.yml -f docker-compose.prod.yml config`（prod 合并）均通过；`docker compose build` 两镜像均成功构建。
+
+---
+
+## 2. 方案 A：单机 docker compose（推荐起步）
+
+适合：单台服务器 / VPS，起步验证。前提：服务器已装 Docker（含 Docker Compose v2 插件）。
+
+### 2.1 装 Docker + 拉代码
+
+```bash
+# 服务器上（以 Ubuntu 为例）安装 Docker Engine + compose 插件
+curl -fsSL https://get.docker.com | sh
+docker --version && docker compose version   # 确认 compose v2 可用
+
+# 拉代码
+git clone <你的仓库地址> writer-work-flow
+cd writer-work-flow
+git checkout main       # 或你的发布分支
+```
+
+### 2.2 准备生产配置（覆盖 base compose 的 dev 缺省）
+
+base `docker-compose.yml` 是**开发导向**（pg 弱口令 `writer/writer`、`5432` 对外发布、`APP_ENV=dev`、
+`CREDENTIAL_ENC_KEY` 用 dev 占位默认）。生产加固的**覆盖文件 `docker-compose.prod.yml` 已随仓库提供**（无需手写），
+与 base 叠加使用即可。它把安全项全部改为**从宿主 env 强制注入**（缺失即拒绝启动）：
+
+- `pg`：`POSTGRES_PASSWORD=${POSTGRES_PASSWORD}` 强口令、端口仅绑 `127.0.0.1:5432`、`restart: unless-stopped`。
+- `api`：`APP_ENV=prod`、`LOG_JSON=true`、`CREDENTIAL_ENC_KEY`/`CORS_ORIGINS`/`DATABASE_URL*`（用同一强口令）全从 env。
+- `web`：`NEXT_PUBLIC_API_BASE`（构建期 build arg + 运行期 env）指向公网 API、`API_BASE_INTERNAL=http://api:8000`。
+
+你只需在**仓库根**准备一个 `.env`（compose 自动读取做 `${...}` 插值；**chmod 600、勿入库**，已被 `.gitignore` 忽略）：
+
+```bash
+# .env（compose 变量插值用；chmod 600，勿入库）
+POSTGRES_PASSWORD=<强随机口令>
+CREDENTIAL_ENC_KEY=<§2.3 生成的 Fernet key>
+CORS_ORIGINS=https://writer.example.com          # 前端真实来源，逗号分隔；禁通配 *
+NEXT_PUBLIC_API_BASE=https://writer.example.com  # 浏览器可达的公网 API（经反代）
+```
+
+> prod 覆盖层对 `POSTGRES_PASSWORD`/`CREDENTIAL_ENC_KEY`/`CORS_ORIGINS`/`NEXT_PUBLIC_API_BASE` 用
+> `${VAR:?...}`（必填）语义——**任一缺失，`docker compose ... config`/`up` 直接报错拒起**，从设计上杜绝
+> 「带 base 弱口令/占位 key 上生产」。完整清单见 [§2.6 生产 env 清单](#26-生产-env-清单)。
+
+### 2.3 生成并妥善保管 CREDENTIAL_ENC_KEY
+
+⚠️ **这是最关键的一步**。用 Fernet 生成一把新密钥（`.env.example` 里那把是开发占位，**生产禁用**）：
+
+```bash
+# 任一装了 cryptography 的环境（也可用仓库 uv 环境）
+uv run python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
+# 或纯 python：python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
+```
+
+把输出的一行密钥填进 §2.2 的 `.env` 的 `CREDENTIAL_ENC_KEY`，并**离线备份**（密码管理器/密钥库）。
+
+> **丢失 = 灾难**：所有已录入的 provider 凭据（存在 Postgres 里、用它加密）将**永久不可解密**，
+> 只能清空后重新录入。轮换密钥需先用旧钥解密全部凭据、再用新钥重加密（当前无自动轮换脚本，
+> 见 §6）。**切勿**复用 `.env.example` 里的占位 key，那等于凭据未加密。
+
+### 2.4 构建镜像 + 跑迁移 + 起服务
+
+```bash
+# 在仓库根，带上覆盖文件
+export COMPOSE="docker compose -f docker-compose.yml -f docker-compose.prod.yml"
+
+# 1) 构建两个应用镜像
+$COMPOSE build
+
+# 2) 先起数据库
+$COMPOSE up -d pg
+# 等 pg 健康（compose 已配 healthcheck）
+$COMPOSE ps    # 看 pg 是否 healthy
+
+# 3) 跑数据库迁移（含 LangGraph checkpointer 建表）—— 见下方两种方式
+```
+
+**迁移的关键事实**：`alembic upgrade head` 一条命令会做**两件事**——
+(a) 建/升级 16 张业务表；(b) 迁移 `d3e4f5a6b7c8_langgraph_checkpoint_setup` 会调用 LangGraph 的
+`checkpointer.setup()` 建 `checkpoints/checkpoint_blobs/checkpoint_writes/checkpoint_migrations`
+四张检查点表。**checkpointer 的建表只在迁移里发生，绝不在应用运行时**（符合 CLAUDE.md「LangGraph」纪律）。
+所以**部署时必须先把迁移升到 head，应用才能正常写章/审稿/续跑**。
+
+api 镜像现已随包 `alembic.ini`（§1.5 已修复 1），**推荐直接在 api 容器里跑迁移**（无需宿主装 uv）：
+
+**方式一（推荐）——在 api 容器里跑迁移：**
+
+```bash
+$COMPOSE run --rm api uv run alembic upgrade head
+$COMPOSE run --rm api uv run alembic check    # 可选：确认无漂移
+```
+
+> 该临时容器与 api 服务共享同一 env（含 `DATABASE_URL*`/`CREDENTIAL_ENC_KEY`），直连 compose 内网的 `pg`，无需暴露端口。
+
+**方式二（备选）——从宿主机 checkout 跑迁移**（宿主已装 uv 时可用；prod 覆盖层把 pg 绑到 `127.0.0.1:5432`）：
+
+```bash
+# 宿主机装 uv：curl -LsSf https://astral.sh/uv/install.sh | sh; export PATH="$HOME/.local/bin:$PATH"
+cd writer-work-flow && uv sync
+DATABASE_URL="postgresql+asyncpg://writer:${POSTGRES_PASSWORD}@127.0.0.1:5432/writer" \
+DATABASE_URL_SYNC="postgresql+psycopg://writer:${POSTGRES_PASSWORD}@127.0.0.1:5432/writer" \
+CREDENTIAL_ENC_KEY="${CREDENTIAL_ENC_KEY}" \
+  uv run alembic upgrade head
+```
+
+**4) 起全部服务：**
+
+```bash
+$COMPOSE up -d
+$COMPOSE ps       # api/web 应为 running（注意它们无 healthcheck，看不到 healthy）
+```
+
+### 2.5 健康检查
+
+```bash
+# API：根 + health 端点（均返回 200 JSON）
+curl -f http://127.0.0.1:8000/          # {"service":"ww-api","status":"ok"}
+curl -f http://127.0.0.1:8000/health    # {"status":"ok"}
+
+# Web：首页
+curl -fI http://127.0.0.1:3000/
+
+# 看日志（api 启动会校验 CREDENTIAL_ENC_KEY、seed 单用户桩、reap 僵尸 job）
+$COMPOSE logs -f api
+```
+
+若 api 启动即退出，最常见原因是 `CREDENTIAL_ENC_KEY` 非法（base compose 已注入 dev 默认；
+生产覆盖层要求经 env 提供合法 Fernet key，见 §2.3）——日志会显示 CredentialKeyError 相关堆栈。
+
+部署完成后，**打开前端「设置」页录入 LLM provider 凭据**（§1.4），产品才能真正调用模型。
+
+### 2.6 生产 env 清单
+
+生产用 `docker-compose.prod.yml` 覆盖层，以下变量必须在**仓库根 `.env`**（compose 自动读取做 `${...}` 插值；
+`chmod 600`、勿入库）或宿主环境变量提供。带 `:?` 者缺失即 `config`/`up` **报错拒起**。
+
+| 变量 | 必填 | 消费方 | 说明 |
+|---|:---:|---|---|
+| `POSTGRES_PASSWORD` | ✅ | pg + api(`DATABASE_URL*`) | pg 强随机口令，替换 base 弱口令 `writer/writer`。api 连接串复用它。 |
+| `CREDENTIAL_ENC_KEY` | ✅ | api | Fernet key（§2.3 新生成，**勿用 `.env.example` 占位值**）。api 启动即校验；解开全部已存 provider 凭据的唯一钥匙，须离线备份。 |
+| `CORS_ORIGINS` | ✅ | api | 浏览器跨源白名单，逗号分隔，**禁通配 `*`**（如 `https://writer.example.com`）。 |
+| `NEXT_PUBLIC_API_BASE` | ✅ | web（**构建期**内联 + 运行期） | 浏览器可达的公网 API 基址（经反代）。改它必须**重新 `docker compose ... build web`**（构建期内联进 bundle）。 |
+| `APP_ENV` | 覆盖层已固定 `prod` | api | 无需手设（prod 层写死）。 |
+| `LOG_JSON` | 覆盖层已固定 `true` | api | 无需手设（prod 层写死）。 |
+| `API_BASE_INTERNAL` | 覆盖层已固定 `http://api:8000` | web(RSC) | 无需手设（prod 层写死）。 |
+
+> LLM provider key（DeepSeek/Kimi/OpenAI…）**永不进 env**——部署后在应用「设置」页录入、加密落库（§1.4）。
+
+生成 `.env` 骨架（示例）：
+
+```bash
+cat > .env <<'EOF'
+POSTGRES_PASSWORD=<强随机口令>
+CREDENTIAL_ENC_KEY=<uv run python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())" 的输出>
+CORS_ORIGINS=https://writer.example.com
+NEXT_PUBLIC_API_BASE=https://writer.example.com
+EOF
+chmod 600 .env
+```
+
+---
+
+## 3. 反向代理 + HTTPS
+
+生产应在应用前放一层反代做 TLS 终止、单一入口、并（配合 §6）做访问控制。
+拓扑：浏览器 → 反代(443) → `web:3000`（页面/RSC）与 `api:8000`（`/api` 或独立子域）。
+
+> 注意 `NEXT_PUBLIC_API_BASE` 的构建期内联：浏览器直接打 API 的地址在**构建 web 镜像时**就定死了。
+> web `Dockerfile` 已暴露 `ARG NEXT_PUBLIC_API_BASE`、prod compose 的 `web.build.args` 会传入它——改这个基址后**必须重新 `docker compose ... build web`** 才生效（重启不改已构建 bundle）。
+> 若走「同源 `/api` 前缀反代」，构建时把 `NEXT_PUBLIC_API_BASE` 设为该前缀；若走「api 独立子域」（如 `api.example.com`），同理构建期注入。
+
+### 3.1 Caddy（推荐，自动证书）
+
+```caddy
+# Caddyfile —— 自动申请/续签 Let's Encrypt 证书
+writer.example.com {
+    # 后端 API：同源 /api/* 反代到 api 容器（去掉 /api 前缀按你的前端约定调整）
+    handle_path /api/* {
+        reverse_proxy api:8000
+    }
+    # 其余流量到 Next 前端
+    reverse_proxy web:3000
+
+    # SSE 长连接：关掉缓冲，避免审稿/写章流被缓存卡住
+    reverse_proxy api:8000 {
+        flush_interval -1
+    }
+}
+```
+
+将 Caddy 也放进 compose（与 api/web 同网络，用服务名访问），暴露 80/443。
+
+### 3.2 Nginx（手动 / certbot 证书）
+
+```nginx
+server {
+    listen 443 ssl;
+    server_name writer.example.com;
+
+    ssl_certificate     /etc/letsencrypt/live/writer.example.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/writer.example.com/privkey.pem;
+
+    # 前端
+    location / {
+        proxy_pass http://web:3000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+
+    # 后端 API（含 SSE：写章/四审流）
+    location /api/ {
+        proxy_pass http://api:8000/;
+        proxy_set_header Host $host;
+        proxy_http_version 1.1;
+        proxy_set_header Connection "";      # SSE：保持长连接
+        proxy_buffering off;                 # SSE：关缓冲，事件即时下发
+        proxy_read_timeout 3600s;            # 长任务/流式容忍
+    }
+}
+```
+
+> 无论 Caddy/Nginx，**SSE 必须关代理缓冲**（写章、四审都是事件流），否则前端进度条会卡住。
+
+---
+
+## 4. 方案 B：PaaS / 托管平台
+
+容器化已就绪（两个 Dockerfile + standalone 前端），可托管到 PaaS。共性：**用托管 Postgres**，
+在平台面板设 env（尤其 `CREDENTIAL_ENC_KEY`、`CORS_ORIGINS`、`DATABASE_URL*`），
+部署后照 §2.4 跑一次 `alembic upgrade head`。provider key 仍在应用设置页录入（不进平台 env）。
+
+### 4.1 Fly.io
+
+- 两个 app：`fly launch` 分别为 api（`apps/api/Dockerfile`，构建上下文=仓库根）与 web（`apps/web/Dockerfile`，上下文=`apps/web`）。
+- Postgres 用 `fly postgres create`（或外部托管 PG），把 `DATABASE_URL`/`DATABASE_URL_SYNC` 设成其连接串（注意驱动前缀 `+asyncpg`/`+psycopg`，Fly 给的是原生 `postgres://`，需自行加前缀）。
+- `fly secrets set CREDENTIAL_ENC_KEY=... CORS_ORIGINS=... POSTGRES_PASSWORD=...`。
+- 迁移：镜像已含 `alembic.ini`（§1.5 已修复 1），可用 Fly `[deploy] release_command = "uv run alembic upgrade head"` 在每次发布前自动跑迁移，或 `fly ssh console` 手动跑。
+- web 的 `NEXT_PUBLIC_API_BASE` 在**构建期**注入（Fly build args → Dockerfile `ARG NEXT_PUBLIC_API_BASE`，已暴露）。
+- api 内部端口 8000、web 内部端口 3000，在 `fly.toml` 的 `internal_port` 对应。
+
+### 4.2 Render
+
+- 两个 Web Service（Docker 运行时），分别指向两个 Dockerfile；web 的 Docker build context 设 `apps/web`，api 设仓库根。
+- Postgres 用 Render Managed Postgres，把内部连接串填进 api 的 `DATABASE_URL*`（加 `+asyncpg`/`+psycopg` 前缀）。
+- 在 api service 的 Environment 填 `CREDENTIAL_ENC_KEY`/`CORS_ORIGINS`/`APP_ENV=prod`/`LOG_JSON=true`。
+- 迁移：用 Render 的 **Pre-Deploy Command** 跑 `uv run alembic upgrade head`（镜像已含 `alembic.ini`，§1.5 已修复 1）。
+- web 与 api 的互通用 Render 的内部地址；`API_BASE_INTERNAL` 指向 api 内部 URL，`NEXT_PUBLIC_API_BASE`（构建期 build arg）指向 api 公网 URL。
+
+> 两个平台的共同注意点：`NEXT_PUBLIC_API_BASE` 仍是**构建期内联**（改它须重构 web 镜像）；`alembic.ini` 已随镜像，迁移可在容器/release 命令里跑。
+> HEALTHCHECK 已内建于镜像，平台存活探测可直接复用或按平台惯例另配 `/health`（api）/`/`（web）。
+
+---
+
+## 5. 迁移与升级流程
+
+### 5.1 常规升级
+
+```bash
+export COMPOSE="docker compose -f docker-compose.yml -f docker-compose.prod.yml"
+
+git pull                      # 拉新代码（含新迁移 / schema.d.ts）
+$COMPOSE build                # 重建 api/web 镜像
+# 先升迁移到 head（含新增业务表 + 可能的 checkpointer 变更），再滚动重启（见 §2.4）
+$COMPOSE run --rm api uv run alembic upgrade head   # 在 api 容器内跑迁移（镜像已含 alembic.ini）
+$COMPOSE up -d                # 用新镜像重启 api/web（pg 不动）
+
+# 冒烟
+curl -f http://127.0.0.1:8000/health && curl -fI http://127.0.0.1:3000/
+```
+
+顺序要点：**先迁移、后换应用镜像**——新代码通常假设 schema 已到 head。若后端 schema 有变，
+记得升级前已在开发侧 `pnpm gen:api` 重生成并提交了 `apps/web/lib/api/schema.d.ts`（§1.2），
+否则 web 构建/类型会漂移。
+
+### 5.2 回滚
+
+```bash
+# 应用回滚：切回上一个 tag/commit 重建重启
+git checkout <上一个可用 tag>
+$COMPOSE build && $COMPOSE up -d
+
+# 数据库回滚（谨慎）：按需降级一版
+$COMPOSE run --rm api uv run alembic downgrade -1
+```
+
+> ⚠️ DB 降级可能丢列/丢表数据，且 `d3e4f5a6b7c8` 的 `downgrade()` 会 `DROP` 四张 checkpoint 表
+> （在跑的写章/链任务会丢控制流状态）。**回滚前先备份**（§7.3）。业务表回滚同理不可逆，优先「向前修复」。
+
+---
+
+## 6. 安全红线（单用户原型的硬约束）
+
+⚠️ **本产品没有认证、没有多租户、没有登录**（`users`/`owner_id` 是桩，见 CLAUDE.md「Prototype scope」）。
+任何拿到 URL 的人都能读写全部小说数据、录入/触发用花你钱的 LLM 凭据。因此：
+
+1. **绝不裸暴露到公网。** 至少满足其一：
+   - 只在 **VPN / 内网 / SSH 隧道**内访问；
+   - 反代前加 **IP 白名单** 或 **HTTP Basic Auth**（Caddy `basic_auth` / Nginx `auth_basic`）；
+   - 或**先补一层认证**再上公网（当前无，属产品级改造）。
+2. **Postgres 不对公网开放。** base compose 把 `pg` 发布到 `5432:5432`（全网卡）。生产**必须**改成
+   仅回环 `127.0.0.1:5432:5432`（§2.2）或删掉端口映射只走 compose 内网。**改掉 base 里的弱口令 `writer/writer`**。
+3. **CORS 显式白名单，禁通配。** `CORS_ORIGINS` 必须是精确来源；后端已在启动断言不含 `*`
+   （`allow_credentials=True` 下 `*` 会被浏览器拒且语义危险）。别为图省事放宽。
+4. **`CREDENTIAL_ENC_KEY` 的密钥管理与轮换：**
+   - 用 §2.3 生成的**新** Fernet key，绝不用 `.env.example` 占位值；
+   - 存进密钥库 / 平台 secrets，`.env` `chmod 600` 且**不入库**；
+   - **备份它**（丢了 = 所有 provider 凭据不可解密）；
+   - 轮换需「旧钥解密全部凭据 → 新钥重加密」（当前无自动脚本，轮换前规划停机 + 备份）。
+5. **provider key 只走应用设置页**（加密落库），永不写进 env/compose/日志（§1.4）。
+6. **日志脱敏已内建**：structlog 结构化日志按 CLAUDE.md「Logging」纪律**不记全 prompt/正文**（记长度/哈希）、
+   **不记 API key**。保持这一约束，别在自建反代/中间件里回退成明文全量日志。
+7. **HTTPS 强制**（§3），别让凭据/正文走明文。
+
+---
+
+## 7. 可观测性与运维
+
+### 7.1 健康端点
+
+- `GET /` → `{"service":"ww-api","status":"ok"}`
+- `GET /health` → `{"status":"ok"}`
+
+两者均无鉴权、返回 200，可作反代/编排的存活探测目标。
+api/web 的 Dockerfile **已内置** `HEALTHCHECK`（§1.5 已修复 5）：api 用 stdlib `urllib` 打 `/health`、web 用 `node http` 打 `/`——`docker compose ps` 直接显示 `healthy`，反代/平台亦可复用。
+
+### 7.2 结构化日志
+
+- 后端 structlog；**生产设 `LOG_JSON=true`** 输出 JSON，便于日志系统采集/检索。
+- 每个请求带 `request_id`（贯穿 assemble→write→四审→accept 一条链），也进错误响应信封——
+  用户报错时可用它端到端 grep。
+- 采集：`docker compose logs`，或把容器 stdout 接到你的日志栈（Loki/ELK/云日志）。
+
+### 7.3 备份 Postgres（含凭据库）
+
+数据全在 `pgdata` 卷 + Postgres 里，**包含加密后的 provider 凭据**。定期逻辑备份：
+
+```bash
+export COMPOSE="docker compose -f docker-compose.yml -f docker-compose.prod.yml"
+
+# 逻辑备份（推荐）
+$COMPOSE exec pg pg_dump -U writer -d writer -Fc > backup_$(date +%F).dump
+
+# 恢复
+$COMPOSE exec -T pg pg_restore -U writer -d writer --clean < backup_YYYY-MM-DD.dump
+```
+
+> **备份数据库还不够**：`CREDENTIAL_ENC_KEY` 要**单独异地备份**——DB 里的凭据是密文，
+> 没有这把钥匙备份也解不出（§2.3 / §6）。两者分开保管、都要备。
+
+### 7.4 成本账本（LLM 调用）
+
+每次 LLM 调用都按 `ARCHITECTURE §4.8` 的字段集记结构化日志（provider/model/tier/token 数/耗时/`request_id` 等），
+喂成本账本。运维时用这些日志：
+- 核对每章/每次生成的 token 与花费；
+- 排查慢/失败调用（网关的路由/回退/熔断也在此可见）；
+- 用 `request_id` 关联「一次写章」的整条链。
+
+采集方式同 §7.2（JSON 日志接入日志栈后按字段聚合）。
+
+---
+
+## 附：核心事实速查
+
+- **服务/端口**：`pg`(5432, 唯一健康检查 `pg_isready -U writer`) · `api`(8000) · `web`(3000)。
+- **镜像**：均本地构建；api 上下文=仓库根，web 上下文=`apps/web`（standalone）。
+- **必填 env**：`CREDENTIAL_ENC_KEY`（启动即校验，缺失/非法则 api 起不来）。
+- **迁移**：`alembic upgrade head` 同时建业务表 + LangGraph checkpointer 表；checkpointer 只在迁移建表，不在运行时。
+- **provider key**：不进 env，部署后在设置页录入、加密落库。
+- **部署面缺口已全部修复**（§1.5）：api 镜像含 `alembic.ini`；base compose `api` 注入 `CREDENTIAL_ENC_KEY`/`APP_ENV`/`LOG_JSON`/`CORS_ORIGINS`、`web` 设 `API_BASE_INTERNAL` + `NEXT_PUBLIC_API_BASE` build arg；api/web 内置 HEALTHCHECK；生产加固走 `docker-compose.prod.yml` 覆盖层（强口令/回环 pg/prod env/`restart`）。
+- **部署命令**：`docker compose build`（dev）或 `docker compose -f docker-compose.yml -f docker-compose.prod.yml build`（prod）→ `... run --rm api uv run alembic upgrade head` → `... up -d`。
+- **红线**：单用户无认证 → 不裸暴露公网；pg 不对外；CORS 禁 `*`；`CREDENTIAL_ENC_KEY` 备份+轮换。

+
+> AI 辅助的**中文网文写作工作流**，以 Web 应用形态交付。核心理念：**把写长篇当软件工程做**——先立架构（世界观 / 角色 / 大纲），对着规格逐章生成，每章写完即测（多维审查），全程维护单一真相源（数据库）。
+
+作者不再让 AI「一口气瞎写十万字」，而是像写代码一样：需求（立项）→ 架构（设定库）→ 建模（角色卡）→ 接口（大纲）→ 实现（逐章生成）→ 测试（写完即审）→ 集成（验收更新全局状态）→ 回归（全书一致性）。AI 是「灵感增幅器 + 质检员」，作者始终掌控创意。
+
+---
+
+## 功能总览
+
+- **引导式立项** — 一句灵感走向连载：选题材 / 基调 / 结局走向 / 叙事视角，AI 起草世界观、主角、金手指、总纲方案，一键建库。
+- **设定库（Codex）** — 结构化的单一真相源：
+  - 角色卡（外貌 / 动机 / 性格 / 背景 / 口癖 / 性格弧光 / 人物关系图）
+  - 世界观（力量体系 / 势力 / 地理 / 词条）
+- **大纲 / 细纲** — AI 排分卷分章骨架，逐层细化到场景清单，并提示伏笔回收窗口。
+- **写章（SSE 流式）** — 注入设定 + 文风指纹，按 genre-aware 的网文写作教条（黄金三章、章末钩子、爽点密度）流式产出本章草稿。
+- **五审（写完即审）** — 一致性 / 伏笔 / 文风 / 节奏 四审 + 人物塑造（advisory 建议性）。审查器**只读**，不静默改稿。
+- **验收事务（HITL）** — 人在环中：作者裁决冲突后，唯一写入路径提交；未解决冲突阻断验收。章节摘要从**最终已验收文本**抽取，绝不污染真相源。
+- **创作工具箱（15 个生成器）** — 声明式 skill 框架，「加生成器 = 加一份声明」：脑洞 / 书名 / 简介 / 取名 / 金手指 / 词条 / 黄金开篇 / 细纲 / 续写 / 扩写 / 降 AI / 拆书，外加世界观 / 角色 / 大纲。
+- **模板库** — 复用与沉淀常用创作模板。
+- **多 Provider LLM 网关** — 路由 / 回退 / 熔断的自建薄网关；Agent 只声明能力 tier，网关按配置映射到 provider+model；支持 Kimi Code 订阅 OAuth（device flow）。
+- **沉浸式写作体验** — 纸感暖色 + 夜读双主题（`data-theme` 切换）、写作台专注模式（隐藏侧栏加宽正文）、`⌘K` 命令面板（跨页跳转 / 执行命令）、应用内帮助页 [`/help`](http://localhost:4000/help)（功能介绍 + 新手上手）。UI 对标编辑部式暖奶油设计语言，全程尊重 `prefers-reduced-motion` 与 WCAG AA。

+
+## 技术栈（已锁定）
+
+| 层 | 选型 |
+|---|---|
+| 前端 | **Next.js + TypeScript**（仅 UI；经 OpenAPI 生成的 TS 客户端调后端，无手写共享类型） |
+| 后端 | **Python + FastAPI**（async，SSE） |
+| 编排 | **LangGraph**（写→审→验收 图，Postgres checkpointer 可恢复） |
+| LLM 访问 | 自建**薄网关**，覆盖 `anthropic` + `openai`（baseURL 兼容 DeepSeek/Kimi/Qwen/GLM）+ `google-genai` |
+| 结构化输出 | **Pydantic + instructor** |
+| ORM / 迁移 | **SQLAlchemy 2.0（async）+ Alembic** |
+| 存储 | **Postgres**（原型不启用 pgvector） |
+| 长任务 | FastAPI BackgroundTasks + `jobs` 表（原型不引入独立队列） |
+
+工具链：**uv**（Python workspace，8 个成员）+ **pnpm**（前端）。Python 3.12+，Node 22。
+
+---
+
+## 快速开始
+
+前置：Python 3.12+ · Node 22 · [uv](https://docs.astral.sh/uv/) · pnpm · Docker
+
+> **本地端口（宿主已 +1000，防与其他项目冲突）**：前端 **http://localhost:4000** · 后端 **http://localhost:9000**（API 文档 `/docs`）· Postgres **localhost:6432**。容器内部端口不变（3000 / 8000 / 5432），只改宿主发布端口；要改回默认各减 1000 即可。接线：前端 `apps/web/.env.local` 的 `NEXT_PUBLIC_API_BASE=http://localhost:9000` 指向后端；后端 `.env` 的 `CORS_ORIGINS` 放行 `http://localhost:4000`、`DATABASE_URL` 指向 `localhost:6432`。
+
+```bash
+# 1. 克隆后，安装后端依赖（仓库根，uv workspace）
+uv sync
+
+# 2. 安装前端依赖
+cd apps/web && pnpm install && cd ../..
+
+# 3. 配置环境变量（CREDENTIAL_ENC_KEY 为必填的凭据加密 Fernet key，启动即校验）
+cp .env.example .env
+#    生产请重新生成：
+#    uv run python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
+
+# 4. 起 Postgres 并跑迁移
+docker compose up -d pg
+uv run alembic upgrade head
+
+# 5. 起后端 API（http://localhost:9000，文档 /docs）— 宿主端口 +1000
+uv run uvicorn ww_api.main:app --port 9000 --reload
+
+# 6. 起前端（另开终端，http://localhost:4000）— pnpm dev 已内置 -p 4000
+cd apps/web && pnpm dev
+```
+
+或一键起全套（pg + api + web，宿主端口均已 +1000）：
+
+```bash
+docker compose up   # web → :4000 · api → :9000 · pg → :6432
+```
+
+> **LLM API Key 不放 `.env`**：在应用设置页 **`/settings/providers`** 录入，密文存于数据库凭据库（用 `CREDENTIAL_ENC_KEY` 加密）。`.env` 里只有那把加密主密钥本身。
+
+---
+
+## 工具链 & 门禁
+
+改动声明「完成」前须全绿（TDD 先红后绿，覆盖率 ≥ 80%）。
+
+**后端**（仓库根）：
+
+```bash
+uv run ruff check .            # lint
+uv run ruff format .           # format
+uv run mypy packages apps      # 类型
+uv run pytest -q               # 单元 + 集成（需 pg：docker compose up -d pg）
+uv run alembic check           # 改过模型后校验无迁移漂移
+uv run pytest -q --cov --cov-report=term-missing --cov-fail-under=80   # 覆盖率门禁
+```
+
+**前端**（`apps/web`）：
+
+```bash
+pnpm lint
+pnpm typecheck
+pnpm test            # vitest（范围 lib/**：纯逻辑 + hooks）
+pnpm build
+pnpm test:coverage   # 覆盖率门禁（阈值 80%）
+```
+
+**改过后端 schema** 后重生成 TS 客户端：
+
+```bash
+cd apps/web && pnpm gen:api
+```
+
+CI 见 `.github/workflows/ci.yml`（backend job 带 pg service 跑 ruff/mypy/alembic/pytest；frontend job 跑 gen:api/lint/typecheck/test）。

+## 文档地图
+
+四份 spec 分层，每层细化上一层；实现暴露的规格缺口须回写对应 spec。
+
+| 文档 | 回答什么 | 何时读 |
+|---|---|---|
+| [`PRODUCT_SPEC.md`](./PRODUCT_SPEC.md) | 是什么 & 为什么 —— 问题、功能（含 P0/P1/P2 优先级）、数据模型、端点、Agent | 理解范围或某功能 |
+| [`UX_SPEC.md`](./UX_SPEC.md) | 长什么样 —— 信息架构、用户流、页面线框、组件、视觉 token（纸感 / warm-cream 主题） | 做任何 UI |
+| [`ARCHITECTURE.md`](./ARCHITECTURE.md) | 怎么实现 —— 完整 DDL、网关内部、编排引擎、API 契约、横切关注点 | 实现后端 / 数据 / 网关 |
+| [`DEV_PLAN.md`](./DEV_PLAN.md) | 按什么顺序 —— Phase 0–5，每个任务标注学科 skill | 挑下一个任务 |
+| [`PROGRESS.md`](./PROGRESS.md) | 交付到哪了 —— 权威状态台账 + 变更日志 | 开工前必读 |
+
+冲突裁决：更具体 / 更靠后的文档为准（`ARCHITECTURE` > `UX_SPEC`/`DEV_PLAN` > `PRODUCT_SPEC`）。协作与开发规范见 [`CLAUDE.md`](./CLAUDE.md)。
+
+---
+
+## 测试与原型边界
+
+- **测试**：TDD 强制（先写失败测试）；三层——单元（一个节点/函数/Repository，mock IO）→ 集成（FastAPI 端点 + DB + mock 网关）→ E2E（写→审→验收，mock 网关）。**所有测试一律 mock LLM，绝不命中真实 LLM API**。覆盖率门禁 ≥ 80%。
+
+原型作用域，以下**明确不做**（勿误用于生产）：
+
+- **单用户，无 auth / 多租户** —— `users` / `owner_id` 为占位桩。
+- **无向量检索 / pgvector** —— 记忆注入是确定性按需选择（显式点名 + 主要角色 + 最近 N 章），非向量搜索（向量检索列 P2）。
+- **无独立任务队列** —— 长任务走 FastAPI BackgroundTasks + `jobs` 表。
+- 不做模型微调、内容分发 / 发布平台对接、移动原生 App。
