-### 镜像构建的唯一安全入口（2026-08 HEL-235 起）
+### 服务器本地目录更新与构建（日常推荐）
 
-生产机 `192.168.200.11` 上的 `/opt/1panel/docker/compose/xiaobaifupan` 只是历史文件树：
-不是 Git 仓库、内容停在旧提交、与线上镜像不一致，且其 `compose.yaml` 会把构建结果打进
-`xiaobai-review:latest`。**禁止在该目录（或任何服务器工作树）里 `docker build` /
-`docker compose build`**，否则会把已上线功能悄悄打回旧版。
-
-唯一安全构建方式是在有仓库检出、能免密 SSH 到部署机的机器上运行：
-
-```bash
-tools/build_image.sh <提交号> <镜像tag>
-# 示例：tools/build_image.sh cefc86917d89 verify-hel235-cefc869
-```
-
-该脚本的行为约束：
-
-- 先 `git fetch`，再把提交号解析为完整 SHA，解析失败立即中止，绝不使用本地脏状态或服务器旧目录；
-- 构建前读取当前线上容器镜像的 `org.opencontainers.image.revision`，用 Git 祖先关系确认候选提交包含线上全部历史；落后 `main`、旁支或错误提交会直接退出，并打印线上提交、候选提交、文件差异和将丢失的提交；
-- 镜像 tag 必须以 `-<提交短号7位>` 结尾（如 `hel234-cefc869`），禁止 `latest`、`rollback-*`；
-- 通过 `git archive <提交> | ssh 部署机 docker build -` 流式构建，服务器上不存在构建用工作树；
-- 构建后回读镜像 label 里的 `org.opencontainers.image.revision`，与预期提交不一致则删除镜像并中止；
-- 每次构建在部署机 `~/xiaobai-build/BUILD_LOG.tsv` 留痕，可追溯每个镜像的来源提交。
-
-构建只产出镜像，不启动、不替换任何容器；换版用新 tag 起新容器，回滚用既有镜像 tag 重跑。
-
-### 使用 Gitea 更新程序（旧方式，生产机禁用）
-
-代码仓库为：
+生产机 `192.168.200.11` 的 `/opt/1panel/docker/compose/xiaobaifupan` 自 2026-08-29（HEL-235B）
+起已是受 Git 管理的工作目录，只跟踪 Gitea `main`（仓库
+`http://192.168.200.36:3200/leefer/xiaobai-review.git`）。由于目录顶层归 root，
+`.git` 存放在部署账号家目录（外部 Git 目录方案）：
 
 ```text
-http://192.168.200.36:3200/leefer/xiaobaifupan.git
+~/xiaobai-build/repos/xiaobai-review.git          Git 元数据（分支/历史/索引）
+/opt/1panel/docker/compose/xiaobaifupan           工作目录（程序文件本体）
+~/xiaobai-build/update-from-main.sh               一键更新+构建入口
+~/xiaobai-git                                    便捷查看（status/log/diff）
 ```
 
-首次在服务器部署代码时，可以直接克隆到目标目录：
+日常更新只需要在服务器上执行一条命令：
 
 ```bash
-sudo mkdir -p /opt/xiaobai-review
-sudo chown "$USER":"$USER" /opt/xiaobai-review
-git clone http://192.168.200.36:3200/leefer/xiaobaifupan.git /opt/xiaobai-review
-cd /opt/xiaobai-review
+~/xiaobai-build/update-from-main.sh            # 更新到 main 并构建 main-<短号> 镜像
+~/xiaobai-build/update-from-main.sh verify-tag main-a8732f5   # 部署前复核镜像与 main 一致
 ```
 
-私有仓库会提示输入 Gitea 用户名和密码或访问令牌。不要把密码写入仓库 URL、
-`compose.yaml` 或脚本。然后把原 `.env` 与 `data/` 放回该目录；这两项已被 Git
-忽略，后续拉取代码不会覆盖数据库与密钥。
+脚本在构建前强制完成五道校验，任一不符立即停止、不产出镜像：
 
-如需部署管理员私有问师，通过 NAS 文件管理器将本地
-`data/private-mentor-skills/` 复制到服务器项目的同名 `data` 目录，并保持目录仅由
-部署账号和容器运行用户读取。该内容不会通过 Gitea 同步。
+1. `git fetch` 成功（连不上 Gitea 即停）；
+2. 必须在 `main` 分支（智能体不得用功能分支直接当正式线）；
+3. 工作区无未提交改动、无多余文件；
+4. 只允许快进合并到 `origin/main`（分叉即停）；main 新增/删除顶层文件时会给出
+   需管理员执行的精确清单（目录顶层归 root）；
+5. 构建后回读镜像 `org.opencontainers.image.revision`，与 `main` 提交不一致则删除镜像。
 
-每次更新前先创建 SQLite 一致性备份，再拉取并重建容器（注意：`docker compose up -d --build`
-从服务器本地工作树构建，仅适用于来源可信的全新环境；生产机 `192.168.200.11` 禁用，
-请用 `tools/build_image.sh` 构建后换容器）：
+镜像 tag 固定为 `main-<提交短号7位>`（不带提交号的模糊 tag 一律禁止）；每次构建在
+`~/xiaobai-build/BUILD_LOG.tsv` 留痕。构建只产出镜像，不启动、不替换容器；换版与
+回滚步骤见 `~/xiaobai-build/README.md`。
 
-```bash
-cd /opt/xiaobai-review
-docker compose exec -T xiaobai-review python -c "import sqlite3; s=sqlite3.connect('/app/data/review.db'); d=sqlite3.connect('/app/data/review-before-update.db'); s.backup(d); d.close(); s.close()"
-git pull --ff-only origin main
-docker compose up -d --build
-docker compose ps
-curl --fail http://127.0.0.1:8765/api/health
-```
+`compose.yaml` 的镜像名与 revision 标签同样做了强校验：直接 `docker compose up -d --build`
+会因缺少 `XIAOBAI_GIT_REV` / `XIAOBAI_GIT_SHORT` 变量而拒绝执行，避免再出现构建进
+`latest` 的模糊版本。需要用 compose 时先 `export` 这两个变量（值以
+`~/xiaobai-build/xiaobai-git rev-parse HEAD` 为准），或直接用上面的脚本。
 
-`docker compose up -d --build` 会原地替换应用容器，不删除宿主机的 `data` 目录。
-数据库迁移会在新容器启动时自动执行。若 `git pull --ff-only` 提示本地代码有修改，
-先用 `git status` 查明原因，不要用强制重置覆盖 `.env` 或 `data`。
+### 智能体高级入口：Git 归档流式构建
 
-### 不使用 Git 时更新（生产机禁用）
+有仓库检出、能免密 SSH 到部署机的智能体可以用 `tools/build_image.sh <提交号> <镜像tag>`
+从任意明确提交流式构建（`git archive | ssh docker build`），tag 同样必须以
+`-<提交短号7位>` 结尾，构建后回读 revision 校验并留痕。用于在服务器不便拉取时的
+应急构建；日常正式线仍应走 `main`。
 
-`docker compose build` 会从服务器本地目录构建，来源提交不可追溯。生产机
-`192.168.200.11` 上禁止使用本节方式，一律改用上一节的 `tools/build_image.sh`。
+### 历史方式（已废弃）
 
-重新上传代码后执行：
-
-```bash
-docker compose down
-docker compose build --pull
-docker compose up -d
-```
-
-`docker compose down` 不会删除宿主机的 `data` 目录。不要使用带有手工删除
-`data` 目录的清理命令。
+早期文档建议在服务器重新 `git clone` 一份或手工上传代码后 `docker compose up --build`。
+这两条路径已废弃：服务器上**只允许存在一个受管工作目录**（上述
+`/opt/1panel/docker/compose/xiaobaifupan`），任何脱离 Git 校验的本地构建都会把
+来源提交变成不可追溯状态，禁止使用。

-当前包含集合竞价、涨停池、炸板池、跌停板、昨日涨停、涨停表现、市场天梯、板块轮动、题材库、人气热榜、龙虎榜和个人复盘工作区。交易日快照与同步记录保存在本地 SQLite 数据库 `data/review.db`。
+## 主要功能
 
-集合竞价中心采用盘前生命周期：9:15 前显示预告，9:15–9:25 明确等待最终竞价，9:25–9:30 自动读取并重试最终竞价筛选，9:30 后停止更新并冻结为复盘归档。当前 Tushare 只提供 9:25 最终竞价快照，不将其表述为动态虚拟撮合行情。
+登录后左侧共 16 个页面，另有一个内嵌页「策略持续跟踪」。交易日快照保存在本地 SQLite 数据库 `data/review.db`。
 
-第三阶段加入了机构席位、席位别名、个股复权日 K、资金流、自选股、涨停原因修订、个股笔记、每日复盘和历史数据回补。
+- **情绪周期**：0–100 情绪温度与阶段判定（默认首页）
+- **涨停池 / 炸板池 / 跌停板 / 昨日涨停 / 涨停表现**：封板结构、炸板、跌停与昨日反馈
+- **市场天梯**：按连板高度排列的市场梯队
+- **板块轮动**：近若干交易日板块热力与成分下钻
+- **集合竞价**：盘前生命周期；9:30 后停止更新并冻结为复盘归档。当前数据源提供 9:25 最终竞价快照，不是动态虚拟撮合行情
+- **题材库 / 人气热榜 / 龙虎榜**：题材成分、双榜人气、席位与游资档案
+- **智能选股**（会员）：六阶段策略、精选策略库、自然语言编译为受控公式后的确定性筛选与滚动回测；候选需手动加入后才进入五交易日跟踪
+- **问师**（会员）：按选定的游资思维 Skill 单师对话；新增公开角色时在 `游资skills` 下增加含 `SKILL.md` 的目录，并在 `游资skills/mentor_catalog.json` 登记。管理员私有角色放在 `data/private-mentor-skills`（不进 Git / 镜像）
+- **问天**（会员）：观势 / 观气 / 观心。卦象、干支、节气与气机由本地程序确定性计算，大模型只负责文字解释。此前仅冻结过界面视觉方案，现已解冻；问天可纳入后续数据与功能迁移，本阶段不主动重做视觉。
+- **我的复盘**：手工交易日志、每日复盘、提醒中心与复盘助手；不接券商、不自动下单
 
-股票代码在桌面端悬停后会显示分时与日 K 快速预览，默认优先展示日 K；移动端点击代码后从底部打开预览面板。股票详情以及板块、题材、指数详情均可在日 K 与最新分时之间切换。日 K 复用个股详情缓存；分时优先使用 iFinD，东方财富仅作隔离的展示兜底，并使用短时内存缓存。图表数据不写入主行情、不参与情绪、选股或问天计算；不可用时明确显示“分时不可用”，不会用日 K 模拟分时走势。
+全局能力：日间 / 夜间主题、股票代码悬停预览日 K 与分时、`Ctrl + K` 全局搜索。图表数据不写入主行情，也不参与情绪、选股或问天计算。
 
-智能选股包含六阶段盘后候选、29 套精选策略、自定义公式 DSL、自然语言公式编译、候选排名和滚动回测。阶段与精选策略在当日行情更新后由后台确定性计算；自定义选股由用户手动执行，LLM 只负责编译自然语言条件，不参与候选筛选。竞价、估值、财务、资金、人气和席位等字段按已登记的数据可用性进入因子库，缺失时明确显示覆盖问题。
+## 技术栈
 
-候选只有经用户手动加入后才进入五交易日持续跟踪，展示 T+1 开盘/收盘、T+3、T+5、最大涨幅与最大回撤。提醒中心支持手工日期提醒，并在策略首日反馈和五日跟踪完成时生成账号私有的站内提醒。

+- 问师、问天解释、复盘助手、自然语言编译公式：需配置 OpenAI 兼容接口；未配置时市场数据页仍可用
 
-问天模块包含三个相互独立的部分：观势以市场数据生成三才六爻，用于观察“势”，行情缺失或自动取象明显偏差时可显式手动校准六爻，人工结果与自动来源严格区分；观气依据干支、精确节气、五运六气及客主加临关系观察“运”，行业五行仅作传统取象归类；观心先准备1秒，再完成5轮“吸3秒、顿2秒、呼4秒”，随后以六次三枚铜钱起卦、察念和解卦完成一次不输入问题的问心仪式。卦象、干支、节气与气机关系均由本地确定性程序计算，LLM只负责解释，不参与起卦或改动结果。
+## 安装与启动
 
-问天模块使用项目本地的 `lunar-python` 计算历法，并使用 `data/iching_zh.json` 中的固定六十四卦、卦辞和爻辞。第三方授权见 `THIRD_PARTY_NOTICES.md`。
+仓库根目录即为运行目录（`server.py`、`requirements.txt` 都在根目录）。

-管理员通过页面右上角“系统管理”保存公共 Tushare Token、平台主/辅助模型、会员每日额度和后台刷新开关。所有用户读取同一份 SQLite 行情快照，不再分别配置行情 Token。已有个人凭据中的 Tushare Token 会在升级时迁移到系统配置并从个人凭据移除。
+## Docker 使用
+
+局域网或服务器部署使用仓库根目录的 `Dockerfile` 与 `compose.yaml`。容器监听 `8765`，默认以非 root 用户运行，并把宿主机 `./data` 挂到容器内 `/app/data`。
+
+1. 复制 `.env.example` 为 `.env`，填入 `APP_ENCRYPTION_KEY` 以及行情 / 模型等初始化配置。密钥不会返回到浏览器。
+2. `compose.yaml` 构建时要求带上当前 Git 提交号，避免打出无版本标签的镜像：
+
+```bash
+export XIAOBAI_GIT_REV="$(git rev-parse HEAD)"
+export XIAOBAI_GIT_SHORT="$(git rev-parse --short=7 HEAD)"
+docker compose build
+docker compose up -d
+```
+
+3. 检查健康接口：
+
+```bash
+docker compose ps
+curl http://127.0.0.1:8765/api/health
+```
+
+健康响应类似 `{"ok": true, "storage": "sqlite", "account_required": true}`。
+
+完整的迁移、持久化、防火墙、备份、恢复与正式线构建入口见 [DOCKER_DEPLOY.md](DOCKER_DEPLOY.md)。`.env` 必须与数据库成对备份；丢失 `APP_ENCRYPTION_KEY` 后无法恢复加密资料。

+独立行情数据中枢（HEL-382 / P0）。与 `xiaobai-review` 同仓库、不同容器、不共享数据库文件。
+本阶段不部署现网；只提供可本地运行、可自测的底座和盘后正式数据链路。
+
+## 做什么
+
+- SQLite WAL `datahub.db`，容器名 `xiaobai-datahub`，端口 `8766`
+- Tushare 盘后正式数据：交易日历、股票主档、daily、daily_basic、adj_factor、index_daily、moneyflow、stk_auction
+- 暂存 → 校验 → 整批原子发布 → 可回滚
+- `/v1` 稳定接口（`X-Datahub-Token`）
+- `/admin/` 最小管理后台（总览 / 数据源 / 调度 / 发布 / 数据集 / 审计）
+- 东财/腾讯/同花顺/选股宝/AKShare/iFinD 适配器位已预留，本阶段不拉实时源
+
+## 单位口径（相对现站）
+
+现站 `xiaobai-review` 按 Tushare 原始单位入库、展示时再换算。中枢在归一化层一次换算：
+
+| 字段 | Tushare / 现站 | 中枢 canonical |
+|---|---|---|
+| `daily.amount` / `index_daily.amount` | 千元 | 元（×1000） |
+| `daily.vol` / `index_daily.vol` | 手 | 股（×100） |
+| `moneyflow.*_amount` | 万元 | 元（×1e4） |
+| `daily_basic.total_mv` / `circ_mv` | 万元 | 元（×1e4） |
+| `stk_auction.amount` | 元 | 元 |
+
+差异为口径升级，golden 测试按上表对照，不为 0 的字段都有说明。

+- 管理后台：http://127.0.0.1:8766/admin/

+- `/v1/*` 必须带请求头 `X-Datahub-Token`

+## Docker（独立 compose，不改现网 review 服务）
+
+```bash
+cd xiaobai-datahub
+cp .env.example .env   # 填密钥
+mkdir -p data
+docker compose build
+docker compose up -d
+```
+
+仓库根目录另有 `compose.datahub.yaml`，供总工以后与现有 `compose.yaml` 叠加部署，本卡不执行现网 `up`。
+
+## 自测
+
+```bash
+cd xiaobai-datahub
+python -m unittest discover -s tests -v
+```
+
+不调用真实 Tushare；用内存/临时库和假适配器。
+
+## 历史回补
+
+交易日历默认从 `20160101` 拉到今天后 30 天；盘前 `precheck` 与手动回补都走同一 UPSERT，可重复执行。
+
+网站实际使用的指数（上证、深成、创业板、沪深300）按交易日增量发布，默认覆盖 260 个交易日（大于现有 90 天窗口，并覆盖智能选股基准回看）。已发布日期默认跳过。
+
+```bash
+cd xiaobai-datahub
+python -m datahub history-backfill
+# 可选：--calendar-start 20160101 --index-days 260 --force
+```
+
+管理后台也可手动跑 `history_backfill` 任务，或 `POST /admin/api/backfill` 且 `dataset=history`、确认词 `history:full`。
+
+区间接口在 `meta.coverage` / `meta.incomplete` 标明覆盖是否完整；网站只读接入把不完整区间视为不可用并回旧链路。个股日 K 的 90 天区间查询依赖已核实，本阶段不回补全市场历史。
+
+## 备份
+
+每日 00:40 任务把 `datahub.db` 备份到 `data/backups/`（保留 14 份）。也可手动：
+
+```bash
+python -c "from pathlib import Path; from datahub.db import HubDB; HubDB(Path('data/datahub.db')).backup_to(Path('data/backups/manual.db'))"
+```
+
+## 安全
+
+- 密钥只以 `configured / 末4位 / 更新时间` 出现在后台，不进日志、不进 `/v1`
+- HTTP 解析失败只记录“请求不是合法 JSON”，不把请求正文、密码或 Token 写入容器日志
+- 回滚、补数需重新输入密码 + 确认词
+- 容器非 root（uid 10002）、read_only、cap_drop ALL
