 # 2026-09-13
 
+2026-09-13 | CHG | 备好 Bark 通知增强（自定义图标/分组/重要警告/图片/角标）：Kuma 官方 provider 不支持这些参数，改为「只读挂载覆盖 `/app/server/notification-providers/bark.js`」实现；素材用 Pillow 手绘（icon/down/up 三张）自托管到 `/data/www/bark-assets/`；**因沙箱连续拦截 SSH，部署改由用户执行 `.workbuddy/tmp/deploy-bark-custom.ps1`，尚未落地**
+2026-09-13 | FIX | 本机取图脚本踩坑：PIL 波形归一化数值超出画布（v=-6 → 偏移 6×振幅）导致尖峰压到文字上；改为所有波形值控制在 [-1,1] 并加 assert 断言
 2026-09-13 | CHG | Uptime Kuma 接入 Bark 告警：新增通知渠道「Bark 手机推送」（type 必须写 `Bark` 首字母大写，端点用容器网关 `http://172.17.0.1:8081/<key>`），已关联全部 9 个监控；用临时监控触发真实 DOWN 完成端到端验证（Bark 日志实测收到并返 200）后清理
 2026-09-13 | DEP | 安装用户级技能 `design-taste-frontend`（taste-skill v2，源 github.com/Leonxlnx/taste-skill，上游路径 skills/taste-skill/SKILL.md）；安装前完成安全审计（P2 安全，纯 Markdown 无脚本）；description 追加中文触发词；来源与审计记录见 `~/.workbuddy/skills/design-taste-frontend/SOURCE.md`
 2026-09-13 | FIX | 本机 git 走系统代理（HTTP_PROXY=127.0.0.1:58412）导致 github clone 失败（Empty reply / CONNECT 502）→ 清空代理 env 后用 `curl --noproxy "*"` 拉 codeload tarball 再解压可正常下载；另 Bash 工具在本机不可用（shim 报 dirname: command not found），需改用 PowerShell

 ### Uptime Kuma（status.xpcool.com，2026-09-13 部署）
 - 镜像 `louislam/uptime-kuma:2.5.3`（2.x 稳定线；1.x 已停维护，v2 有破坏性变更，跨大版本需迁移数据库）。
-- 启动参数：`--restart unless-stopped -p 127.0.0.1:3001:3001 -e TZ=Asia/Shanghai -v /data/uptime-kuma:/app/data --memory 512m`。服务器内存仅 3.7G 且 **swap=0**，必须限内存，避免 OOM 波及同机其他容器。

 - **v2 首次启动是「选择数据库」引导页**（逻辑在 `/app/server/setup-database.js`，读 `data/db-config.json`），选 SQLite 即可，之后进入创建管理员账号页。Uptime Kuma **没有找回密码入口**，密码丢失只能改数据库/清 2FA，务必记牢。
 - nginx 反代**必须透传 WebSocket**（`proxy_http_version 1.1` + `Upgrade`/`Connection` 头），否则面板无限重连、状态刷不出来。
 - **证书**：腾讯云免费 DV，CN/SAN 均为 `status.xpcool.com`，**有效期仅 3 个月（至 2026-12-12），到期必须重新申请并替换**；落点 `/data/nginx/ssl/status.xpcool.com/`（crt/pem/csr 644、key 600），本地源 `E:\CentOS\ssl\status.xpcool.com_nginx\`。部署时用 `openssl x509 -pubkey | md5` 与 `openssl pkey -pubout | md5` 比对，确认证书与私钥配套。

   - 脚本：`.workbuddy/tmp/kuma-bark-setup.sh`（幂等写入）、`.workbuddy/tmp/kuma-bark-verify.sh`（端到端验证 + 自清理）；改库前必备份 `/tmp/kuma.db.backup.<时间戳>`。
   - **端到端验证方法（推荐复用）**：临时插一个指向 `http://127.0.0.1:9/` 的监控（`interval=20/retry_interval=20/maxretries=0`）→ 重启容器 → 十几秒即 DOWN 并推送 → 查 `docker logs bark` 确认真的收到 GET 推送（200）→ 删掉临时监控与其 heartbeat 再重启。全程不清真站点，可靠性最高。

+  - 宿主机 `/data/uptime-kuma-patch/bark.js` ←→ 容器 `/app/server/notification-providers/bark.js`（`:ro`）。补丁源码在 `.workbuddy/tmp/bark.js`，改动点集中在 `statusParams()` 与 `additionalParameters()`，均以中文注释标了「xpcool 定制」。
+  - 行为：DOWN → `level=critical`（重要警告，穿透静音/专注）+ `volume=5` + `badge=auto`（角标自增）+ `isArchive=1` + 异常配图；UP → `badge=0`（清角标）+ 恢复配图。`call=1`（持续响铃 30s）**默认关闭**，要开就在 config 里加 `"barkCall": true`。
+  - 所有项都可用通知 `config` 里的同名字段覆盖：`barkIcon / barkGroup / barkSound / barkLevel / barkVolume / barkCall / barkBadge / barkImageDown / barkImageUp / barkBadgeReset`。**但 UI 里保存通知会重写 config、丢掉这些额外字段** —— 保持默认行为即可（补丁有兜底默认值），要改就走 SQL。
+  - 素材自托管在 `https://status.xpcool.com/bark-assets/{icon,down,up}.png`（落点 `/data/www/bark-assets/`，nginx 新增 `location /bark-assets/`，`alias + default_type image/png + expires 7d`）。**必须公网 HTTPS 可匿名访问**：图是手机端收到通知后自己去拉的。
+  - 素材由 `.workbuddy/tmp/make-bark-assets.py`（Pillow 手绘）生成，纯几何 + 微软雅黑文字，体积 22~78 KB。
+  - **⚠️ 升级 uptime-kuma 镜像后**：`bark.js` 会被挂载覆盖成旧版实现，必须重新对照新版官方 `bark.js` 更新补丁（或临时去掉挂载）。
+  - **⚠️ 重建容器必须带回挂载**，否则补丁失效（表现为：通知还发，但图标/重要警告/配图/角标全没了）。完整启动参数见上。
+  - 部署脚本：`.workbuddy/tmp/deploy-bark-custom.sh`（远端执行，幂等）+ `.workbuddy/tmp/deploy-bark-custom.ps1`（本机一键：上传 → 部署 → 端到端验证，日志写 `.workbuddy/tmp/logs/`）。

+//  bark.js  —— xpcool 定制版（基于 Uptime Kuma 2.5.3 官方实现）
+//
+//  为什么要定制：官方 Bark provider 只支持 endpoint / group / sound 三个参数，
+//  且图标写死成 GitHub 上的 Uptime Kuma 图标。本项目需要：
+//    1. 自定义推送图标（自托管 PNG，手机端直接拉取）
+//    2. 推送消息分组（可选 config.barkGroup 覆盖）
+//    3. 重要警告 level=critical，穿透静音 / 专注模式（仅 DOWN）
+//    4. 图片推送通知 image，按状态区分「异常图 / 恢复图」
+//    5. 设置角标 badge（DOWN 自增、UP 清零）
+//    6. 附带：call=1 持续响铃、isArchive=1 自动保存（仅 DOWN）
+//
+//  部署方式：宿主文件 /data/uptime-kuma-patch/bark.js 只读挂载覆盖本路径。
+//  ⚠️ 升级 uptime-kuma 镜像后需重新核对此文件与新版官方实现的差异。
