-# OTA 文件夹
+# OTA 热更新目录
 
-此目录存放 manifest 文件。manifest-stable.json 是 CI 构建时动态生成的产物，
-也提交到仓库通过 raw URL 供客户端拉取。
+## 文件说明
 
-## 文件
+| 文件 | 用途 |
+|------|------|
+| `version.txt` | v5 嵌入式初始化——格式: `版本\|URL\|SHA256` |
+| `h5-manifest-stable.json` | 发行渠道（stable）——格式: `{latest, min_version, url, sha256}` |
+| `h5-manifest-beta.json` | 测试渠道（beta） |
+| `h5-manifest-nightly.json` | 开发渠道（nightly） |
+| `h5/index-vN.html` | 可下载的热更新页面 |
 
-- `gen-manifest.sh` — 构建后运行，计算 APK SHA256 并生成 manifest-stable.json
-- `manifest-stable.json` — stable 渠道
-- `manifest-beta.json` — beta 渠道
-- `manifest-nightly.json` — nightly 渠道
+## 推送补丁
 
-## 流程
+```bash
+# 更新所有渠道到 v7
+cd ota
+bash push-hotfix.sh 7 all
 
+# 只更新 nightly 渠道
+bash push-hotfix.sh 7 nightly
+
+# 手动推送
+git add ota/
+git commit -m "hotfix: v7"
+git push
 ```
-CI 构建 APK → ./ota/gen-manifest.sh → git push manifest-stable.json
-手机 App → raw URL 拉取 manifest → 比较版本 → 下载 APK → SHA256 校验
+
+## 格式
+
+**h5-manifest-*.json:**
+```json
+{
+  "latest": "0.1.0-dav-android-6",
+  "min_version": "0.1.0-dav-android-5",
+  "url": "https://git.childish-ghost.com/.../ota/h5/index-v6.html",
+  "sha256": "33a16632..."
+}
+```
+
+**version.txt:**
+```
+0.1.0-dav-android-6|https://.../ota/h5/index-v6.html|33a16632...
 ```

+#!/bin/bash
+# push-hotfix.sh — 推送 H5 热更新补丁到 Gitea
+#
+# 用法:
+#   ./push-hotfix.sh 7 stable        # 只更新 stable 渠道
+#   ./push-hotfix.sh 7 all           # 更新全部三个渠道
+#   ./push-hotfix.sh 7 beta nightly  # 更新指定渠道
+#
+# 流程:
+#   1. 创建 ota/h5/index-v{VER}.html（如果不存在则从模板生成）
+#   2. 计算 SHA256
+#   3. 更新 ota/h5-manifest-{CHANNEL}.json
+#   4. 如果是稳定版，更新 ota/version.txt
+#   5. git add + commit + push
