+# TraceIQ 财务分析工作台
+
+响应式 Web 前端 + Django API + PostgreSQL。基于分享会话、医院财务 Excel 原始附件及 AG Grid 开发计划实现，当前交付是可运行、经过本地回归的核心业务版本，不等于全部需求完成或已获生产上线认证。缺口与上线门禁见 [验收状态](docs/acceptance.md)。
+
+## 已实现
+
+- XLSX / UTF-8 CSV 导入、双行表头、原始解释保留、字段语义确认、产品毛利率及自营产品范围配置。
+- 原始文件私有存储、组织内文件 SHA-256 去重、导入事务、持久队列、PostgreSQL worker 崩溃恢复。
+- 实际收入、成本、毛利、两种明确 ROI 公式、去重人数、客单价、毛利率、产品扣率、自营收入、升单率、原价客单价。
+- 同比、环比、自定义等长月份范围；缺基期禁止比较，缺成本显示不可用，缺月份趋势断开。
+- 总览、异常追踪、贡献分解、自定义下钻层级、面包屑、原始行证据分页、CSV / XLSX 证据导出。
+- 个人设置保存/取消/预览与乐观锁；调查备注与状态持久化；账号启停、角色及科室范围、操作审计。
+- 本地规则助手；可选 OpenAI Responses 结构化意图接口，用户同意后仅发送问题与维度/当前筛选，查询仍受后端权限约束。
+
+当前原附件没有医生、成本和连续月度数据，不会生成虚构的医生排名、ROI 或环比结论。毛利是根据产品分类毛利率计算的贡献值，不等同于已审计净利润。
+
+## 技术结构
+
+| 目录 | 职责 |
+| --- | --- |
+| `frontend/src` | React 19 / TypeScript、AG Grid、ECharts、响应式 UI |
+| `finance/importing.py` | 解析、映射、Decimal 校验、批量导入 |
+| `finance/analysis.py` | 权限内聚合、比较、异常与贡献 |
+| `finance/views.py` | 身份认证、受控 API、导出、设置、账号、审计 |
+| `finance/assistant.py` | 规则助手及外部模型意图校验 |
+| `server` | Django 配置、路由、WSGI |
+| `tests` | PostgreSQL 集成测试、Playwright 浏览器回归 |
+| `scripts` | 本地账号初始化、原始附件独立对账 |
+
+后端金额使用 `NUMERIC(44,24)`，Python Decimal 精度 60；JSON 金额为字符串。浏览器 Number 仅用于绘图与显示，不作为账务计算或持久化来源。Excel 精确金额以文本单元格导出，避免 Excel 的 15 位有效数字上限。客户端不会一次加载 33 万条明细，只加载聚合结果，证据查询每页最多 200 行。
+
+## 本地运行
+
+需要 Node.js 22、uv、Python 3.12、PostgreSQL 17。所有示例从仓库根目录执行。
+
+```bash
+uv sync --frozen --python 3.12
+npm ci --registry=https://registry.npmjs.org
+export DATABASE_URL='postgresql://USER:PASSWORD@127.0.0.1:5432/traceiq'
+uv run python manage.py migrate
+PYTHONPATH=. uv run python scripts/init_local.py
+npm run build
+uv run python manage.py collectstatic --noinput
+uv run python manage.py runserver 127.0.0.1:8000 --noreload
+```
+
+另一个终端启动导入 worker：
+
+```bash
+export DATABASE_URL='postgresql://USER:PASSWORD@127.0.0.1:5432/traceiq'
+uv run python manage.py import_worker
+```
+
+访问 `http://127.0.0.1:8000`，本地随机账号保存在 `var/local-access.txt`，文件权限 0600。该脚本拒绝生产模式。开发热更新可在第三个终端运行 `npm run dev`，Vite 将 `/api` 代理到 8000。
+
+本次本机验证使用专属集群 `var/postgres`、端口 55432、库 traceiq：
+
+```bash
+/opt/homebrew/opt/postgresql@17/bin/pg_ctl -D var/postgres -l var/postgres.log -o '-h 127.0.0.1 -p 55432' start
+export DATABASE_URL='postgresql://jianwel@127.0.0.1:55432/traceiq'
+```
+
+该集群只监听本机，使用开发认证策略，不可公开端口或复制到生产。没有设置开机自启。SQLite 仅作轻量开发后备，不保证高精度金额聚合，禁止财务验收和生产使用。
+
+## 生产部署
+
+1. 在独立服务器配置域名 DNS、防火墙及 TLS，创建 `.env`，参考 `.env.example`。生成至少 50 字符随机 SECRET_KEY、数据库强密码，两处数据库密码需一致；密码有特殊字符时 DATABASE_URL 中必须 URL 编码。
+2. 设置准确的 `DOMAIN`、`ALLOWED_HOSTS`、`CSRF_TRUSTED_ORIGINS`。仅开放 Caddy 80/443；数据库与 Gunicorn 不发布主机端口。
+3. 执行 `docker compose --env-file .env config --quiet`，再执行 `docker compose up --build -d`。migrate 服务成功后才启动 web/worker，Caddy 自动申请 HTTPS 证书。
+4. 执行 `docker compose exec web python manage.py bootstrap --username admin --organization '医院财务中心'`，交互输入管理员密码，无默认生产密码。
+5. 执行 `docker compose exec web python manage.py check --deploy`，在隔离预生产环境运行验收，完成下面运维门禁再上线。
+
+默认单个导入 worker 用 PostgreSQL advisory lock 防止重复处理；其他 worker 获取不到锁会退出。worker 异常退出，数据库回滚未完成的 Fact 事务并释放锁，下次启动会重新处理 processing。需要受控停机时先等任务 ready 再停，强制停止会导致整个文件重新导入。通过 `import_file PATH --username admin --confirm-mapping` 的 CLI 导入也入队，不绕过 worker。
+
+`TRUST_PROXY=1` 仅用于 web 无公网直连、反向代理覆盖 X-Forwarded-Proto 和 X-Real-IP 的部署。登录 IP 限流在此模式使用经过校验的 X-Real-IP，未启用时忽略该头。`.env.example` 的 DB_SSLMODE=disable 仅适用同宿主私有容器网络；跨主机数据库用 verify-full 与受信证书。代理上传上限 66 MB、应用文件上限 64 MiB。生产使用环境变量/密钥服务注入密码，不提交 `.env`。
+
+## 备份与运维
+
+- 同时备份 PostgreSQL 与 uploads 卷，不能只备份其中一个。uploads 包含原始财务/客户标识，需加密磁盘、受控访问及留存期限。
+- 低频窗口暂停新上传，等待当前导入完成并停止 worker；用 `pg_dump -Fc` 创建数据库备份，再快照 uploads，记录同一备份批次。将备份放在加密、异地主机或受控对象存储。
+- 恢复到**隔离新库和新卷**，使用 `pg_restore --exit-on-error` 后检查迁移、账号范围、导入状态，执行金额/人数对账，抽查原始行与导出，再切换流量。未完成恢复演练不能上线。
+- 定时执行 `python manage.py clearsessions`；监控 `/api/health`、HTTP 5xx、查询 P95、导入队列等待时间、processing 持续时间、磁盘/数据库容量、失败审计与备份新鲜度。当前未配置外部告警渠道。
+- 管理员忘记密码由运维执行 `python manage.py changepassword USERNAME`，现阶段没有邮件找回、自助密码修改、SSO 或 MFA。
+- 审计记录对网页用户只读，但数据库管理员仍可修改；需要不可抵赖审计时，应外送到独立追加写日志平台。
+- 发布前备份并固定镜像 digest；失败时回滚应用镜像。涉及不可逆数据迁移不得直接反向迁移，按批准的数据库恢复方案操作。
+
+## 测试
+
+测试数据库需要 CREATE DATABASE 权限。测试账号和 fixture 均为虚构数据。
+
+```bash
+uv run ruff check server finance tests scripts
+uv run ruff format --check server finance tests scripts
+uv run python manage.py makemigrations --check --dry-run
+uv run pytest --cov=finance --cov-report=term-missing --cov-fail-under=85
+npm run build
+npm run test:e2e
+npm audit --omit=dev --registry=https://registry.npmjs.org
+uv run pip-audit
+```
+
+Playwright 需要正在运行的本地 API 和 worker，可用 E2E_PASSWORD 指定测试 admin 密码，默认读取本地凭据文件。首次执行 `npx playwright install chromium`。浏览器 fixture 测试会新建 `e2e-finance.csv` 数据集，不可指向正式生产环境。`.github/workflows/ci.yml` 在独立 PostgreSQL 上执行同样流程，尚未推送到远端触发。
+
+原附件只在本机使用，不在仓库中：
+
+```bash
+uv run python scripts/inspect_source.py '/Users/jianwel/Downloads/分析数据_原稿(1).xlsx'
+PYTHONPATH=. uv run python scripts/reconcile_reference.py
+REFERENCE_DATASET_NAME='分析数据_原稿(1).xlsx' npm run test:e2e
+```
+
+## AI 与跨平台
+
+默认 AI_ENABLED=0。启用外部模型需配置 `AI_ENABLED=1`、`OPENAI_API_KEY`、`OPENAI_MODEL`，并完成机构数据处理审批。密钥只在后端。用户自由输入的问题也可能含敏感信息，不能仅凭不发送原始行就认定无隐私风险。模型不能提交 SQL、修改金额或修改账号；输出只允许受控意图，异常/拒答关闭执行。
+
+前端为标准 Web，API 无平台耦合，可由后续 PWA、Tauri 或 Capacitor 客户端复用。当前没有打包桌面/移动客户端，也不在浏览器离线缓存财务数据。
+
+AG Grid Community 默认可运行；设置 `VITE_AG_GRID_LICENSE_KEY` 后注册 Enterprise 模块并启用已接入的侧栏/状态栏。必须自行取得合适的商用许可证。SSRM / Pivot / Master-Detail 尚未接入，不能因存在 Enterprise 依赖就声称已完成这些功能。

+# 验收状态与上线门禁
+
+日期：2026-09-24，Asia/Singapore。本文区分实现状态和验证状态，不把编译成功等同于生产商用验收。
+
+## 公式工作簿与对话新增列
+
+本轮新增校验：对话模型、导出 API 及最终工作簿生成器均只允许引用当前数据映射可计算的指标；模型误报完整或客户端绕过对话直接提交时，服务端仍会拒绝缺少来源字段的自定义列。
+
+> **当前发布判断：** 本轮后端 61 passed、finance 覆盖率 87.66%；公式工作簿版本 3 已改为流式写入，100,000 行产品上限实测峰值 RSS 约 136.4 MB。新增列流程覆盖追问、补充、定义确认、数据映射可用性防护及公式工作簿下载。LibreOffice 重算测试覆盖特定黄金样例；Microsoft Excel、财务口径签字、真实 AI 合规、原附件 332,830 行范围方案及目标环境部署仍未验收。
+
+| 需求 | 状态 | 实现 / 尚缺内容 |
+| --- | --- | --- |
+| 对话定义自定义列 | 已实现；mock 端到端通过 | 用户描述列名、含义、范围及计算；缺项时模型主动追问，补充后结合全对话重审；只接受既有指标/常数和白名单运算树。编辑补充时保留当前定义供核对，未发送的草稿会禁用确认；最多 6 轮，限 10 列、8 层表达式。真实外部模型联调未做。 |
+| 自定义列公式导出 | 已实现；小样本验证通过 | 异步任务生成 XLSX；自定义列引用汇总指标公式，并包含使用说明、参数口径、计算明细、原始证据和对账页；另保留原有证据快照导出。 |
+| Excel 公式引擎验收 | 尚未通过发布门禁 | 消费人数与升单率改用随机去标识 CustomerRoster 固定人数表 + COUNTIFS，不依赖 UNIQUE/FILTER；4 项 LibreOfficeDev 重算测试已通过。Microsoft Excel 仅打开过样本并在公式栏看到 COUNTIFS/SUMIFS；Excel 为只读无法保存重算副本，且所见分组与预期不匹配，故 Excel 实机重算结果仍未验收。身份、分组和期间是固定快照，编辑金额可重算，不支持通过改客户身份改变人数。 |
+| 生产上线资格 | 未完成 | 公式导出最大 100,000 行/200 组，真实附件 332,830 行尚不能一次导出；真实 AI 服务联调、数据出境审批、目标 Excel 兼容、性能及安全审查均未完成。 |
+
+## 最新验证（2026-09-24）
+
+- 对话新增列及公式导出回归：后端全量 `61 passed`，finance 覆盖率 `87.66%`；新增用例覆盖流式工作簿、精确文本条件、未分类对账、Excel 长度限制、公式注入、保留列冲突、任务文件权限/路径、授权快照顺序和路径准备失败恢复。
+
+- 当前源码自动化基线（2026-09-24）：61 passed，finance 覆盖率 87.66%（85% 门槛）；包含列定义追问、数据映射可用性防护、流式导出和 LibreOffice 公式重算回归。Ruff lint/format、TypeScript/Vite 构建、Django check、迁移检查通过。
+- 本轮隔离 SQLite Playwright：3 passed、1 skipped；新增列追问与下载、桌面综合工作流、手机布局通过；原附件 UI 用例因未设置 `REFERENCE_DATASET_NAME` 跳过。隔离数据库和媒体目录位于 `/tmp/caiwu-roadmap-e2e*`；登录成功的正式用例使用临时口令环境变量。
+- 完整临时生产配置下 `check --deploy` 无告警；pip-audit 和 npm audit 均为 0 已知漏洞。Docker 镜像构建未运行（Docker daemon 不可连接），Compose 校验未运行（真实 `.env` 不存在）。
+- 真实附件 PostgreSQL 17 对账通过：332,830 行、5 个分组，收入/毛利/人数与历史独立对账一致，缺成本 332,830 行、ROI 不可用。完整公式工作簿生成基准 96.94 秒、51,532,457 字节、峰值 RSS 3,308,617,728 字节；单机单次生成不等于资源/SLA 通过。
+- 本轮以安装的 LibreOfficeDev 执行 `tests/test_formula_recalculation.py`（3 项）与 `tests/test_formula_recalculation_gross.py`（1 项）：共 4 项通过，覆盖自定义汇总/变化率、编辑明细金额后的联动、零成本 ROI、缺失基期，以及 direct/lookup 毛利来源。该结果不是 Microsoft Excel 实机验收。
+- 流式容量基准：公式版本 3 的 20,000 行合成工作簿生成 5.26 秒、3,265,273 字节、峰值 RSS 77,922,304 字节；100,000 行生成 25.96 秒、16,217,767 字节、峰值 RSS 136,429,568 字节。100,000 行产物 ZIP/OOXML 完整性、7 个工作表、表格关系、版本及汇总公式读取通过；这是本机隔离 SQLite 单次基准，不是目标环境并发 SLA。
+- Microsoft Excel 桌面检查记录：在只读 Excel 中打开 `/tmp/caiwu-excel-validation.xlsx`，公式栏可见 COUNTIFS/SUMIFS；无法保存重算副本，且所选样例分组为 `Test`、与预期不匹配。结果仅证明样本中存在公式，不证明 Excel 计算正确，发布门禁维持未通过。
+- `compose.yaml` 已配置 `cleanup_formula_exports --loop` 常驻清理服务，清理逻辑有 3 项测试覆盖；目标环境仍需确认运行与告警。
+
+## 剩余功能与发布阻断
+| P0 | Microsoft Excel 公式引擎验收 | 已有 LibreOfficeDev 小样本公式缓存证据，仍需目标 Excel Windows/Mac 重算和兼容性验收。 |
+| P0 | 真实附件范围与业务口径 | 100,000 行/200 组产品上限已用流式版本实测；原附件 332,830 行仍超范围，需选择可审计分卷或正式提高上限后再验。财务签字仍未完成。 |
+| P0 | 真实 AI 合规与商用环境 | 真实模型联调、数据出境/隐私审批和目标环境安全验证尚缺。 |
+
+| 优先级 | 未完成项 | 发布影响 / 下一步 |
+| --- | --- | --- |
+| P0 | Microsoft Excel 公式引擎验收 | 人数公式使用静态去重辅助表 + COUNTIFS；仍需目标 Excel Windows/Mac 打开、重算、保存，覆盖人数、升单率、空集、缺期及金额编辑后的计算。 |
+| P0 | 真实附件全量公式导出 | 当前上限 100,000 明细行/200 分组，原附件 332,830 行；100,000 行流式资源压测已完成，仍需定义切分导出并保证跨文件口径，或批准扩大产品范围后做 332,830 行目标引擎验收。 |
+| P0 | 财务业务口径签字 | 确认 N 列实际收入与 I 列实收、退款、成本归属、毛利、ROI、升单、自营产品集和舍入规则；真实附件成本缺失且 ROI 不可用。 |
+| P0 | 外部 AI 合规与真实联调 | 完成真实模型超时/限额/故障演练、数据出境和隐私审批；未批准前保持 AI 关闭。 |
+| P1 | 对话定义可扩展性 | 当前仅支持既有指标/常数与加减乘除；不支持任意 Excel 函数、跨明细新聚合、按零替代/跳过缺失、生成维度列或保存复用定义。新能力需逐项安全与黄金样例验证。 |
+| P1 | 工作簿操作完整性 | 当前固定导出范围，不支持在 Excel 增加明细行后自动扩展所有报表；结构变化需重新导出。验证参数编辑、结构变化提示、模板版本和列字典。 |
+| P1 | 定义体验差距 | 证据弹窗已支持本期/基期切换并通过 E2E；公式定义对话仍没有持久化草稿/定义库。确认复用范围后实现并补 E2E。 |
+| P1 | 商业部署验收 | Docker 构建、HTTPS/证书、PostgreSQL/TLS、备份恢复、并发/SLA、审计监控、渗透测试、AG Grid Enterprise 商用许可需在目标环境验证/审批。 |

+## 测试记录
+- 本轮源码测试：44 passed，finance 覆盖率 86.95%；常规 pytest 在本机 SQLite 测试配置运行，独立 PostgreSQL CI 未启动；另在本机 PostgreSQL 17 隔离库执行原附件对账和完整公式工作簿生成基准。
+- 本轮浏览器回归：完整隔离 SQLite Playwright 3 passed、1 skipped；跳过未配置 `REFERENCE_DATASET_NAME` 的原附件 UI 专测。
+
+- PostgreSQL 17：67 项后端测试通过（22.32 秒），finance 总覆盖率 89.17%，analysis 98%、assistant 90%、importing 86%、views 84%；CI 覆盖率门槛 85%。
+- 检查内容：Decimal 金额、人数去重、加权比率、零分母、退款、缺期、新增/消失分组贡献、XLSX 表头与 lookup、导入原子性、重复上传、非法映射、跨组织/科室隔离、CSRF、会话、登录限流、设置冲突、调查记录、导出公式注入、模型意图白名单与敏感字段最小化、worker 恢复、CLI 初始化。
+- TypeScript / Vite 生产构建通过；Django `check`、迁移检查及完整临时生产变量下的 `check --deploy` 均通过。目标部署环境仍未验收。
+- Python pip-audit 与前端 npm audit（生产依赖）均报告 0 个已知漏洞；这不是渗透测试或未来无漏洞保证。
+- 既有 Playwright 历史记录：3 项用例通过；当前分支 E2E 覆盖见上方 2026-09-24 最新验证，不能用历史结果替代本轮重跑。
+- 回归发现并修复调查控件标签定位与图表网格最小宽度问题。原附件截图为 `reference-desktop.png` / `reference-mobile.png`；截图文件已生成，但工具未可靠展示图片供逐像素人工复核，视觉精修仍应由产品人员验收。
+- 新增可信代理登录限流测试：未启用信任时忽略伪造客户端头，启用后仅接受合法 IP。生产 Caddy 覆盖 X-Real-IP，web 不得直接暴露公网。
+- 产物位于本机 `test-results/`、`playwright-report/`，未提交真实财务数据和凭据。

+## 必须完成的上线门禁
+
+1. 财务负责人确认收入/实收/原价、退款、升单、自营、成本归属与 ROI 定义；补齐缺失的业务口径和字段。
+2. 若要求原开发计划全部功能，补齐上述未完成项并逐项签字。当前版本不能标记为“所有前后端需求已完成”。
+3. 在目标基础设施完成 Docker 镜像构建、HTTPS、数据库认证/TLS、上传限制、非 root 容器及重启恢复验收。
+4. 用目标并发用户数、最大文件/维度基数做导入与查询压力测试，确定 SLA 和资源配额。当前聚合会返回所有分组，高基数维度需 SSRM 或服务端结果窗口。
+5. 完成真实 OpenAI 接口联调、超时/限额演练和数据出境/隐私审批；没有审批时保持关闭。
+6. 外部安全审查与渗透测试、最小权限数据库账号、密钥轮换、加密存储、访问日志脱敏、不可变审计与告警接入。
+7. 执行数据库 + 源文件一致性备份及恢复演练，记录 RPO/RTO，确定留存和删除流程。
+8. AG Grid Enterprise 若启用须有适用商业许可；完成所有依赖许可证盘点。
+
+以上商用门禁不因本地自动化测试通过而自动满足；较早的 44、54 项测试及旧非流式 332,830 行峰值 RSS 约 3.31 GB 均为历史基线，不能替代当前版本的目标环境验收。
