 ## QQBot 插件能力
 
+### Bilibili Card
+
+插件 key：`bilibili-card`。这是事件型内置插件，不新增在线命令；启用后仍需通过账号事件绑定让指定 QQBot 账号接收 `bilibili-card.message`。

 ### BangDream
 
 插件 key：`bangdream`。旧 `bangDream` 作为兼容别名仍可解析；当前源码根目录为 `src/modules/qqbot/plugins/bangdream/src`，按第三期插件结构拆分为 `operations`、`domain/*`、`application`、`infrastructure/integration`、`infrastructure/storage`、`config`、`assets` 和 `theme`，不再使用旧 `tsugu` 子目录、宿主 builtins 包装层或纯转接目录。

 - QQBot 在线命令和自动回复规则都有运行时保底冷却：默认命令 `5000ms`、规则 `30000ms`；即使数据库里旧数据冷却值更低，也按保底值判定，降低频繁触发风控的概率。
 - QQBot 复读机默认阈值为 4，同一会话默认 10 分钟只复读一次，默认只复读 120 字以内普通文本，避免群聊重复内容导致机器人过于频繁地模拟真人发言。
 - QQBot 插件平台统一使用 `plugin.json` manifest 描述插件 key、版本、操作、事件、权限、运行预算和包入口；CLI 负责 create/validate/pack/install-local，后端只暴露受控 SDK 能力并通过插件维度记录安装、配置、账号绑定和运行事件。
+- Bilibili Card 是事件型内置插件：`bilibili-card.message` 只在账号绑定后监听 QQ/NapCat `share/json/xml/lightapp` 卡片或文本里的 Bilibili 链接，`b23.tv` 短链通过平台 `resolveRedirect` 受控 host 能力解析，视频信息从 Bilibili `x/web-interface/view` 获取后回复纯文本摘要。
 - QQBot 同一账号只允许一个有效 NapCat 主容器；绑定新容器时会释放旧绑定和不再共享的旧容器，机器人下线 notice、`isOnline:false` 和 NapCat 容器最新离线日志都会写入账号 `lastError`，普通群成员 kick 不属于账号离线信号；写入 `last_error` 前按 500 字符截断，后续无错误的普通断连不能清空该原因；账号列表拆开展示 OneBot、容器、WebUI 和 QQ 登录态，心跳只代表 OneBot/容器通信，不能推导 QQ 登录态；近期连接只用于避免重连瞬间被旧缓存误伤，后续仍必须以 NapCat WebUI/日志检查判断 QQ 登录态；`qqLoginMessage` 只展示 QQ 登录态消息，WebUI 配置或请求错误留在 `lastError`。
 - NapCat 托管容器必须显式配置 `QQBOT_NAPCAT_IMAGE`，不要依赖 `latest` 默认镜像；生产切换镜像前先 pin 明确版本或 digest 并单账号观察。
 - NapCat 账号新增/编辑支持可选 QQ 登录密码：Admin 只提交 RSA-OAEP 加密后的 `encryptedLoginPassword`，后端解密后必须用显式配置的 `QQBOT_ACCOUNT_SECRET_KEY`（或非默认 `ADMIN_TOKEN_SECRET`）二次加密保存到 `qqbot_account.napcat_login_password_secret`；空值、`change-me` 和历史公开默认值会被拒绝；列表和详情不回显密码，日志会脱敏密码字段。
