docs(lark-apps): align db/file skill references with code

- db-execute: document the third failure-hint case (first statement
  failed → 'No statements were applied').
- db-env-create: describe the re-init conflict by behavior instead of
  quoting a server-side literal message.
- file-list: clarify pretty shows 5 columns; uploader/download_url are
  JSON-only (use +file-get for single-file detail).

-
-把存量单库应用初始化为 `dev` / `online` 多环境数据库。运行时命令事实以 `lark-cli apps +db-env-create --help` 为准。
-
-## 何时用
-
-仅用于存量单库应用需要拆成 `dev` / `online` 两套数据库的场景。普通查看表、查 schema、执行 SQL 不需要先初始化。注意：通过 `+create --app-type full_stack` 新建的应用通常已自带多环境，无需再初始化（重复初始化会返回「已初始化」错误）。
-
-## 命令骨架
-
-- 必填：`--app-id`。
-- `--env`：要创建的环境，由调用方传入，目前只支持 `dev`（默认 `dev`）。
-- `--sync-data`：bool 开关，传 `--sync-data` 则把现有 online 数据复制到新环境；不传则不复制（默认）。
-- risk 是 `high-risk-write`；单库拆成 dev/online 后不可逆。
-
-## 示例
-
-```bash
-lark-cli apps +db-env-create --app-id app_xxx --env dev --dry-run
-lark-cli apps +db-env-create --app-id app_xxx --env dev --sync-data --yes
-```
-
-## 输出契约
-
-- 成功读取 `data.status`、`data.environments`、`data.data_synced`；pretty 会提示是否初始化、多环境列表、是否同步数据。
-- 未确认时返回 `confirmation_required` / exit 10；按 lark-shared 询问用户后再补 `--yes` 重试。
-- 如果服务端提示已启用多环境（`Multi-env is already initialized`），转述状态即可，不要重复初始化。
-
-## Agent 规则
-
-不要静默追加 `--yes`。遇到 confirmation_required 时，按 `lark-shared` 的 exit-10 协议向用户确认不可逆风险；用户明确同意后才在原 argv 末尾追加 `--yes` 重试。

+## 约定（先读）
+
+- **环境 `--env dev|online`（默认 online）**：看表、看结构、数据导入导出、变更追溯、审计、配额、初始化都按环境区分，写操作建议先在 `dev` 验。`+db-env-diff`/`+db-env-migrate` 是「dev→online 发布」语义、`+db-recovery-*` 作用于当前库，二者**没有** `--env`。
+- **本地文件用工作目录内相对路径**：导入 `--file ./orders.csv`、导出 `--output ./out.csv`；路径在别处先 `cd` 过去或改成相对路径。
+- **高危操作必须带 `--yes`**：`+db-env-create`、`+db-data-import`、`+db-env-migrate`、`+db-recovery-apply` 缺省会被确认关卡拦下；动手前先用对应的预览命令或 `--dry-run` 看清影响。
+- **时间参数按口语自然传**（`--since`/`--until`/`--target`），格式见末尾。
+
+## 各命令
+
+### 表与结构
+
+**`+db-table-list`**：列出某环境的数据表。分页 `--page-size`（默认 20）/ `--page-token`（上一页 cursor）。每项给表名、描述、估算行数、大小、列数；要完整列定义 / 索引 / 约束用 `+db-table-get`。只知道业务对象名时，先用它定位可能的表名。
+
+```bash
+lark-cli apps +db-table-list --app-id app_xxx
+lark-cli apps +db-table-list --app-id app_xxx --env dev --page-size 50
+```
+
+**`+db-table-get`**：看单张表的结构。默认 JSON 给结构化的字段 / 索引 / 约束 / 估算行数 / 大小；`--format pretty` 直接输出建表 DDL 文本（给用户看建表语句或做迁移参照时用）。
+
+```bash
+lark-cli apps +db-table-get --app-id app_xxx --table orders
+lark-cli apps +db-table-get --app-id app_xxx --table orders --env dev --format pretty
+```
+
+### 多环境数据库（初始化 + 发布）
+
+**`+db-env-create`（高危）**：把存量单库应用初始化为 dev/online 两套库，不可逆，必须带 `--yes`。`--env` 目前只支持 `dev`（默认 `dev`）；`--sync-data` 把现有 online 数据复制到新环境（不传则不复制）。注意：`+create --app-type full_stack` 新建的应用通常已自带多环境，重复初始化会返回冲突错误（应用已是多环境）——按 `error.hint` 转述状态即可，别重复初始化。
+
+```bash
+lark-cli apps +db-env-create --app-id app_xxx --env dev --dry-run
+lark-cli apps +db-env-create --app-id app_xxx --env dev --sync-data --yes
+```
+
+**`+db-env-diff`**：预览开发环境里待发布到线上的表结构变更，不落地。发布前先看这个。无待发布变更时明确返回「无变更」。
+
+**`+db-env-migrate`（高危）**：把开发环境的结构变更正式发布到线上，不可逆，必须带 `--yes`，返回实际发布的变更条数。发布是异步的，命令会等到完成再返回结果。
+
+> 预览与发布同一端点，故 `+db-env-diff` 也需 `spark:app:write` scope（不是纯只读权限）。
+
+```bash
+lark-cli apps +db-env-diff --app-id app_xxx
+lark-cli apps +db-env-migrate --app-id app_xxx --yes
+```
+
+### 数据导入导出
+
+**`+db-data-export`**：把一张表导出到本地文件。导出格式**只由 `--output` 的扩展名决定**——`.csv` / `.json` / `.sql`，缺省按 `<表名>.csv` 落在当前目录。注意：全局 `--format json|pretty` 只控制**命令自身输出**（成功摘要 / 错误信封）的渲染，**不影响导出文件的格式**；`--output` 后缀必须是 `.csv/.json/.sql` 之一，否则报 validation 错误（exit 2），且不支持导出到 stdout。两道体量约束：
+
+- `--limit`（1..5000，默认 5000）是**行数上限守卫**：表的行数超过它会被整体拒掉（不是「只导前 N 行」）；
+- 导出产物 >1 MB 也会被拒。
+
+超大表别硬导：先用 `+db-execute` 加 `WHERE` / `LIMIT` 缩小范围、分批导。
+
+```bash
+lark-cli apps +db-data-export --app-id app_xxx --table orders --output ./orders.csv
+lark-cli apps +db-data-export --app-id app_xxx --table orders --output ./orders.json --env dev
+```
+
+**`+db-data-import`（高危）**：把本地 csv/json 文件的数据导进表。文件需是 `.csv`/`.json`、≤1 MB，必须带 `--yes`。目标表缺省取文件名去掉**最后一个**扩展名（如 `orders.csv`→`orders`，`orders.2026.csv`→`orders.2026`）；文件名带点号时建议显式传 `--table` 以免落到意外的表名。
+
+```bash
+lark-cli apps +db-data-import --app-id app_xxx --table orders --file ./orders.csv --env dev --yes
+```
+
+**导入/导出限额**：体积 ≤ **1 MB**、行数 ≤ **5000**，导入导出都一样，超限会被拒。超限就分批——导入拆成 ≤1 MB / ≤5000 行的多个文件，导出用 `WHERE` / `LIMIT` 缩小范围。
+
+### 变更追溯与审计
+
+**`+db-changelog-list`**：查表结构变更（DDL）历史——谁、什么时候、改了哪张表、做了什么。可按 `--table` 过滤、按 `--change-id` 精确定位某条、用 `--since`/`--until` 圈时间区间，分页 `--page-size`/`--page-token`。
+
+```bash
+lark-cli apps +db-changelog-list --app-id app_xxx --table orders --since 7d
+```
+
+**`+db-audit-status`**：看审计开关状态。给 `--table` 看单表，不给则列出所有已配置的表（开没开、保留期）。
+
+**`+db-audit-enable` / `+db-audit-disable`**：开 / 关某张表的行级变更审计。`--retention` 设保留期，取值 `7d`/`30d`/`180d`/`360d`/`forever`（默认 `7d`）。不要对已经开启审计的表重复 enable——不确定就先用 `+db-audit-status` 查。
+
+```bash
+lark-cli apps +db-audit-enable --app-id app_xxx --table orders --retention 30d
+lark-cli apps +db-audit-disable --app-id app_xxx --table orders
+```
+
+**`+db-audit-list`**：列出表的行级变更事件（INSERT/UPDATE/DELETE 的前后值与操作人）。`--table` 必填、可重复传多张表；`--since`/`--until` 圈时间。
+- **多表查询**：会先帮用户把不存在、或没开审计的表过滤掉再查，被过滤的表及原因列在结果的 `skipped` 里——据此告诉用户哪些表没纳入及为什么。
+- **单表查询**：不预过滤，表不存在 / 未开审计会直接报错（按 `error.hint` 转述给用户，引导先 `+db-audit-enable`）。
+
+```bash
+lark-cli apps +db-audit-list --app-id app_xxx --table orders --since 24h
+lark-cli apps +db-audit-list --app-id app_xxx --table orders --table users
+```
+
+### 时间点恢复（PITR）
+
+**`+db-recovery-diff`**：预览把库恢复到 `--target` 时间点会带来哪些变更（受影响的表、行数、预计耗时），不落地。同样需 `spark:app:write` scope。
+
+**`+db-recovery-apply`（高危）**：把库恢复到某个时间点，**会覆盖当前数据**，不可逆，必须带 `--yes`。
+
+- 可恢复窗口最长 **7 天**，且不早于**最近一次 `+db-env-migrate`**；超出窗口的目标会被拒。
+- 目标时间点与当前库一致时返回 `no_changes`（空操作），不算失败。
+- 动手前务必先 `+db-recovery-diff` 给用户确认。
+
+```bash
+lark-cli apps +db-recovery-diff --app-id app_xxx --target 2h
+lark-cli apps +db-recovery-apply --app-id app_xxx --target 2026-04-15T10:00:00Z --yes
+```
+
+### 配额
+
+**`+db-quota-get`**：查数据库存储用量（已用量、表数、视图数；配额接入后还会给总配额与使用率）。
+
+```bash
+lark-cli apps +db-quota-get --app-id app_xxx --env dev
+```
+
+## 时间格式（`--since` / `--until` / `--target`）
+
+按用户口语自然传入即可，支持：
+- 相对时间 `7d` / `2h` / `30s`（从现在往前推）
+- 日期 `2026-04-15`
+- 日期时间 `2026-04-15T10:00:00`
+- 带时区的 ISO 8601 `2026-04-15T10:00:00Z` / `2026-04-15T10:00:00+08:00`
+
+## Agent 规则
+
+- 用户说「本地 / 开发库 / 调试库」优先 `--env dev`，线上排查用 `--env online`；数据面写操作（导入 / 审计开关）默认先在 `dev` 验再动 `online`。
+- 看表用 `+db-table-list`，看结构用 `+db-table-get`（要建表语句加 `--format pretty`）；`+db-env-create` 仅用于存量单库拆多环境，新建的 full_stack 应用一般不需要。
+- 四个高危命令（`+db-env-create`、`+db-data-import`、`+db-env-migrate`、`+db-recovery-apply`）动手前先看清影响再带 `--yes`：发布 / 恢复先跑对应预览 `+db-env-diff` / `+db-recovery-diff`，导入无预览命令、可先 `--dry-run` 看请求或先在 `--env dev` 验；不要静默追加 `--yes`，遇 confirmation_required（exit 10）按 lark-shared 协议向用户确认不可逆风险后再补 `--yes` 重试。
+- 导入 / 导出的本地路径用工作目录内相对路径；超大表导出会被行数 / 体积上限拒，改用 `+db-execute` 分批。
+- `+db-audit-list` 多表查询时，把结果里 `skipped` 的表（不存在 / 未开审计）连同原因一并向用户说明，不要让用户以为这些表「没有变更」。
+- 恢复是覆盖式且不可逆：`+db-recovery-apply` 前必须先 `+db-recovery-diff`，并明确告知用户会覆盖当前数据。

+
+## 何时用
+
+用户要在某个妙搭应用里上传 / 下载 / 列出 / 删除文件、拿文件的临时分享链接、或看存储用量时。普通飞书云盘走 [`lark-drive`](../../lark-drive/SKILL.md)；数据库里的表数据走 `+db-*`。
+
+## 命令一览
+
+| 命令 | 做什么 | 关键参数 |
+|---|---|---|
+| `+file-list` | 列出文件，可按名/路径/类型/大小/上传时间过滤 | `--app-id`、过滤器、`--page-size`/`--page-token` |
+| `+file-get` | 查单个文件的元数据 | `--app-id`、`--path` |
+| `+file-sign` | 生成有时效的下载链接（用于分享 / 直接下载） | `--app-id`、`--path`、`--expires-in` |
+| `+file-download` | 把远端文件保存到本地 | `--app-id`、`--path`、`--output` |
+| `+file-upload` | 上传本地文件到应用存储 | `--app-id`、`--file` |
+| `+file-delete` | 按路径批量删除文件 | `--app-id`、`--path`（可重复）、`--yes` |
+| `+file-quota-get` | 查应用的文件存储用量 | `--app-id` |
+
+## 寻址与约定（先读）
+
+- **远端文件统一用 `--path` 精确寻址**（远端路径，带前导 `/`）。只知道文件名时，先用 `+file-list --name <名>` 定位拿到 `path`，再做后续操作。
+- **本地文件 / 输出路径用工作目录内的相对路径**（如 `--file ./report.pdf`、`--output ./out.png`）；路径在别处时先 `cd` 过去或改成相对路径。
+- 上传只接收本地 `--file`：文件名沿用本地文件名，远端路径由平台分配、全局唯一（无需也无法手填）。
+- file 域不区分环境，没有 `--env`。
+
+## 各命令
+
+### +file-list
+列出应用文件，支持精确过滤：`--name`（文件名）、`--path`（远端路径）、`--type`（MIME 类型）、`--size-gt`/`--size-lt`（字节）、`--uploaded-since`/`--uploaded-until`（上传时间区间，时间格式见末尾）。分页 `--page-size`（默认 20）/ `--page-token`。列表每项给名称、路径、大小、类型、上传时间（pretty 表格即这 5 列）；上传者、下载地址（如有）仅在 JSON 输出里，单文件详情用 `+file-get`。
+
+```bash
+lark-cli apps +file-list --app-id app_xxx
+lark-cli apps +file-list --app-id app_xxx --type image/png --uploaded-since 7d
+```
+
+### +file-get
+按 `--path` 查单个文件的元数据。路径不存在时返回明确的「文件不存在」错误。
+
+```bash
+lark-cli apps +file-get --app-id app_xxx --path /1858537546760216.png
+```
+
+### +file-sign
+为指定文件生成一个**有时效的下载链接**——适合发给用户分享、或直接下载。`--expires-in` 设有效期秒数（默认 1 天，最长 30 天）。`pretty` 模式只输出链接本身，便于复制 / 管道；要把到期时间一并告诉用户时用默认 JSON 输出（含到期时间）。
+
+```bash
+lark-cli apps +file-sign --app-id app_xxx --path /1858537546760216.png --expires-in 3600
+```
+
+### +file-download
+把远端文件保存到本地。`--output` 指定保存路径，缺省时按远端文件名保存到当前目录。
+
+```bash
+lark-cli apps +file-download --app-id app_xxx --path /1858537546760216.png --output ./logo.png
+```
+
+### +file-upload
+上传一个本地文件。文件名沿用本地文件名，远端路径由平台分配。单文件上限 100 MB。
+
+```bash
+lark-cli apps +file-upload --app-id app_xxx --file ./report.pdf
+```
+
+### +file-delete（高危）
+按路径批量删除，`--path` 可重复传多个。删除是高危操作，必须带 `--yes`；缺省会被确认关卡拦下。**逐项返回结果**：部分文件删除失败（如某个路径不存在）不影响其余文件，整体仍算成功，失败项在结果里单独标出原因。
+
+```bash
+lark-cli apps +file-delete --app-id app_xxx --path /1858537546760216.png --yes
+lark-cli apps +file-delete --app-id app_xxx --path /a.png --path /b.png --yes
+```
+
+### +file-quota-get
+查应用的文件存储用量（已用量、文件数；配额接入后还会给总配额与使用率）。
+
+```bash
+lark-cli apps +file-quota-get --app-id app_xxx
+```
+
+## 时间格式（`--uploaded-since` / `--uploaded-until`）
+
+按用户口语自然传入即可，支持：
+- 相对时间 `7d` / `2h` / `30s`（从现在往前推）
+- 日期 `2026-04-15`
+- 日期时间 `2026-04-15T10:00:00`
+- 带时区的 ISO 8601 `2026-04-15T10:00:00Z` / `2026-04-15T10:00:00+08:00`
+
+## Agent 规则
+
+- 寻址一律用 `--path`；用户只给文件名时先 `+file-list --name <名>` 定位，多个同名再让用户确认。
+- 上传 / 下载的本地路径用工作目录内相对路径；不在当前目录就 `cd` 过去或改相对路径。
+- 用户要「分享链接 / 临时下载地址」时用 `+file-sign`，把返回的链接转述给用户。
+- 删除前判断意图：已明确要删且授权时可直接带 `--yes`；不确定删哪些时先 `+file-list` 给用户确认。批量删除部分失败不报错，按逐项结果向用户说明哪些成功、哪些没删掉及原因。
