修复 GraalVM 25 原生构建中的 commons-logging 初始化

netty-all 是聚合 pom，会拖进 5 个平台的 native-quic、各架构的 epoll/kqueue/
io_uring 传输以及 htt3/mqtt/redis 等一堆用不到的 codec。主站实际只用
Bootstrap/NioEventLoopGroup/NioSocketChannel/ByteBuf/ByteToMessageCodec/
LengthFieldBasedFrameDecoder/LoggingHandler/Promise，因此收敛为
transport + codec-base + handler（含 buffer/common/resolver 传递依赖）。

效果：jar 68.1MB -> 52.2MB，netty 模块 50 -> 7，进程 RSS 291MB -> 约 227MB。
433 个测试全绿。hutool 未动。

同时把 jar 运行期的 systemd JVM 参数与前后实测数据记入
docs/MEMORY_TUNING_2026-09-21.md，避免这些只存在于服务器 drop-in 的参数
在下次重新部署时丢失。

+# 2026-09-21 低内存调优记录（jar 运行期）
+
+编译机未上线期间，两个后端都以 jar 方式运行。本机为 2 核 / 2.9G，活跃堆很小但 RSS 偏高，
+做了一轮只改 JVM 参数与依赖声明的低内存调优。全程未改业务代码。
+
+## 实测前后对照
+
+| 服务 | 项目 | 调优前 | 调优后 |
+| --- | --- | --- | --- |
+| 主站 lionwebsite | RSS | 291 MB | 约 227 MB |
+| 主站 lionwebsite | jar 体积 | 68.1 MB | 52.2 MB |
+| 主站 lionwebsite | netty 模块 | 50 个 | 7 个 |
+| 主站 lionwebsite | 线程数 | 40 | 37 |
+| 存储节点 storageNode | RSS | 171 MB | 约 155-162 MB |
+| 存储节点 storageNode | netty 模块 | 35 个 | 5 个 |
+| 存储节点 storageNode | 线程数 | 24 | 20-22 |
+
+调优前后堆使用都在 40-52 MB 量级，RSS 的主要成分是元空间、代码缓存与各类映射，
+因此收益主要来自收敛预留和减少类加载面，而不是堆。
+
+## 一、JVM 参数（systemd drop-in，不在版本控制内）
+
+主站 `/etc/systemd/system/lionwebsite.service.d/jar-run.conf`：
+
+    /usr/local/jdk-25/bin/java -Xmx256m -Xss512k -XX:MaxMetaspaceSize=160m \
+      -XX:+UseSerialGC -XX:+UseCompactObjectHeaders \
+      -XX:ReservedCodeCacheSize=96m -XX:+ExitOnOutOfMemoryError \
+      -jar /home/lionwebsite/lionwebsite.jar
+
+存储节点 `/etc/systemd/system/storageNode.service.d/jar-run.conf`：
+
+    /usr/local/jdk-25/bin/java -Xmx192m -Xss512k -XX:MaxMetaspaceSize=96m \
+      -XX:+UseSerialGC -XX:+UseCompactObjectHeaders \
+      -XX:ReservedCodeCacheSize=96m -XX:+ExitOnOutOfMemoryError \
+      -cp /root/gallery/storageNode/storageNode-jar.jar:/root/gallery/storageNode/lib/* lion.Main
+
+取值依据：
+
+- `UseSerialGC`：小堆、低吞吐场景，省掉 G1 的分区元数据与并发标记线程。存储节点原本就是默认 SerialGC，主站原本是默认 G1，本次对齐。
+- `UseCompactObjectHeaders`：对象头 12 到 8 字节，堆内以 String 与 map 节点为主时收益直接。
+- `ReservedCodeCacheSize=96m`：原先 240m 预留，实测主站只用约 14 MB、节点约 6 MB。
+- `-Xmx` 收敛：主站由 384m 到 256m，节点由 256m 到 192m，相对活跃堆仍留 4-6 倍余量。
+
+回滚：恢复同目录 `jar-run.conf.bak.20260921T090605Z`（主站）或
+`jar-run.conf.bak.20260921T090746Z`（节点）后 `daemon-reload` 加 `restart`。
+
+## 二、依赖精简（已入库）
+
+`netty-all` 是聚合 pom，会拖进全部模块。两个后端只用到 NIO 传输与基础编解码，
+因此改为按需声明：
+
+- 主站（netty 4.2.17）：`netty-transport` 加 `netty-codec-base` 加 `netty-handler`。
+  `handler` 用于 `RemoteService` 的 `LoggingHandler` 协议调试日志。
+- 存储节点（netty 4.1.138）：`netty-transport` 加 `netty-codec`。
+  节点侧未使用 `handler` 模块的类，故不声明。4.1 无独立 `codec-base`，编解码基类在 `netty-codec`。
+
+剔除的内容包括 5 个平台的 native-quic、aarch64 与 riscv64 与 osx 的 epoll 与 kqueue 与 io_uring 传输、
+以及 codec-http3 与 mqtt 与 redis 与 smtp 与 stomp 与 xml 与 protobuf 等。
+
+`hutool-all` 未调整。
+
+## 三、已评估但未采用：AOT 缓存
+
+JDK 25 的 `-XX:AOTCache` 可免原生编译生成类缓存。实测交替 A/B 各两轮：
+
+| | 启动耗时 | RSS |
+| --- | --- | --- |
+| 无 AOT | 6.37s / 6.74s | 220.9 MB / 223.1 MB |
+| 带 AOT | 6.27s / 6.36s | 221.4 MB / 222.7 MB |
+
+启动约快 0.2s（噪声量级），RSS 与元空间均无改善，代价是 80 MB 缓存文件且每次发版需重训。
+按降低内存的目标不值得，故未在生产启用。
+
+## 四、遗留与后续
+
+- 原生编译机恢复后应重新评估原生镜像：内存会显著低于 jar，届时上述 JVM 参数失去意义。
+- 存储节点目录内仍保留 `lib.bak.20260921T091617Z`（47 jar）与 `storageNode.jar.bak.*`，为本次回滚路径。
+- 两个 `jar-run.conf` 的 JVM 参数只存在于服务器 drop-in，未纳入版本控制；重新部署时需按本文恢复。

+# 2026-09-08 审查修复与编译交接
+
+本批源码已在本机按问题分别提交，尚未推送、后端编译或部署。编译机恢复后，需要先取得下列仓库的提交，再按现有发布手册构建、验证与上线。此次没有调整鉴权或数据库表结构。
+
+## 提交清单
+
+| 仓库 | 提交 | 内容 |
+| --- | --- | --- |
+| storageNode | cbfd634 | 压缩临时文件、ZIP 完整性校验、失败保留源目录并恢复可重试状态 |
+| lionwebsite-backend | f65c5ad | 下发节点前持久化任务，超时保留记录，原子累加用量 |
+| lionwebsite-backend | 7f823b6 | 修复 Range 解析、读取长度、空文件和越界处理 |
+| lionwebsite-backend | 1e6e3a1 | 上游订阅下载移出全局锁，设置超时，拒绝旧配置/旧请求的刷新结果 |
+| lionwebsite-backend | b15eeaf | 复用连接线程组，登记等待对象后再发送，统一超时/失败/关闭清理 |
+| lionwebsite-backend | 60facae | 关闭图片和 TAR 文件流，合并同图请求，完成后发布缓存，检查转换结果 |
+| lionwebsite-frontend-desktop | 287dc09 | 图片失败继续加载，单图重试，忽略旧页面图片事件 |
+| lionwebsite-frontend-desktop | b0f832c | 退避重连、连接状态提示、唤醒后重连、重连与提交后的全量刷新 |
+| lionwebsite-frontend-desktop | d0eb2f0 | 链接 GID 类型匹配，补充任务提交回归测试 |
+| lionwebsite-backend | a9ba631 | 连接反复断开时重新安排监听，验证缓存失败后可重试 |
+| lionwebsite-backend | d3b18f9 | 修复图片 Key 缓存递归更新与 null 写入，异常时关闭 HTTP 响应 |
+
+各仓库分别保留了原有历史。前端原先未提交的 `index.html`、`vite.config.js`、`llm_readme.md` 以及未跟踪的 `dist/`、`node_modules/` 未纳入本批提交。
+
+## 已验证与待验证
+
+已完成：
+
+- 前端 `node --test tests/*.test.mjs`：9 项通过。
+- 前端生产构建：成功，产物输出到 `/tmp/lionwebsite-review-build`，没有覆盖现有 `dist/` 或线上资源。构建提示主包体积超过 500 kB，本批未做依赖拆包。
+- 各次提交的 `git diff --check` 与最终源码调用链检查。
+
+尚未执行：
+
+- 主站、存储节点的 Java 编译及 JUnit 测试。
+- GraalVM 原生构建、真实节点断连、真实上游下载和生产端到端验证。
+
+**以下 Java 测试仅在编译机的独立工作副本执行，不在生产主站或存储机执行。两个仓库依次运行 `mvn test`，通过后再按现有部署手册构建原生程序。** 新增测试均使用临时目录、Mock 或内存通道，不需要生产数据库和真实上游。
+
+主站新增测试：`GallerySubmissionTest`、`FileDownloadTest`、`SubscriptionRefreshServiceTest`、`RemoteServiceTest`、`PersonalArchiveTest`、`ImageFileCacheTest`、`GalleryKeyCacheTest`。
+
+存储节点新增测试：`DownloadCheckServiceTest`。两个仓库已有的订阅快照测试也应一起运行。
+
+## 行为与接口说明
+
+HTTP 路由、参数名和节点消息格式保持兼容，任务状态继续使用 `已提交`、`下载中`、`等待压缩`、`压缩中`、`下载完成`。
+
+- `POST /GalleryManage`：先保存任务再下发。节点未确认时返回业务 failure，但任务记录仍在，前端刷新后可以重试；不会把已经收到的完成状态写回已提交。新增任务时即计入本周用量，重试不重复计量。
+- 存储节点压缩失败：保留源文件，回到等待压缩状态，30 秒后可自动重试；手动重试会取消等待。仅完整校验通过的 ZIP 才视为完成。
+- 使用 `FileDownload.export` 的文件接口：支持单个普通范围、后缀范围和开放结尾范围；非法或不可满足范围返回 416，`Content-Range: bytes */<size>`；多个范围回退为完整 200 响应；HEAD 不输出正文；普通完整响应不再带 Content-Range。
+- 图片缓存：同一图片的并发请求共享下载，临时文件关闭且转换成功后才发布。下载连接超时 5 秒、读取超时 15 秒，转换超时 60 秒。图片缺失或下载失败仍返回 404，中断可返回 503。
+- 订阅刷新：连接和连接池等待超时 5 秒，读取超时 15 秒；网络操作不占用订阅状态锁。上游 Key、过滤选项或启用状态改变后会使旧缓存失效，旧刷新结果不能重新发布。仅名称修改且刷新失败时保留原有缓存。
+- WebSocket：连接失败按 1/2/4/8/16/30 秒退避，建立连接超时 10 秒；重连后重新读取任务列表和用量。页面恢复可见或网络恢复时重新连接。
+
+## 上线验证重点
+
+按现有发布手册安排存储节点、主站和前端上线，避开正在运行的生产任务。源码修复本身不代表生产已经更新。
+
+1. 新建任务，模拟节点已有归档或立即返回状态，确认数据库与页面均保留完成状态且没有重复行。
+2. 使用临时测试目录制造一次压缩失败，确认源文件保留，恢复目录可写后能重试，损坏 ZIP 不会标记完成。
+3. 下载完整文件和小范围/尾部范围，确认响应字节数；验证空文件和越界请求。
+4. 在测试上游阻塞刷新时修改其他账号/读取快照，确认操作不被网络等待阻塞；旧请求结束后不能覆盖新配置。
+5. 阅读器人为令一张图片失败，确认后续图片继续加载、单图重试有效。
+6. 浏览器断网、恢复网络、切后台再返回，确认连接提示和进度能够恢复。
+
+根目录 `/home/lionwebsite/API_DOCUMENTATION.md` 已追加待发布说明；本文件是这部分接口行为变更的仓库内交接记录。

+# LionWebsite 一键登录（/login）：实现说明
+
+状态：**已全部完成并上线**。主站侧提交 `00e2715`（文档 `dfb647b`、`628f3ad`），
+桌面端 `9b5bc94`；机器人侧由 `debian-qq-chatgpt` 于 host-vm103-debian-qq 完成
+（见共享盘 `tasks/2026-09-21-lionwebsite-login-bot-command/`）。
+关联待办：`td-20260921-a1b2c3`（已归档为
+`todos/archive/done-td-20260921-a1b2c3-lionwebsite-login-tg.md`）。
+
+用户已明确选择**接法 B：共享密钥自签票据**，理由是机器人到主站的网络调用不可靠。
+因此主站**不提供**任何票据签发端点，也不需要机器人侧发起 HTTP 请求——机器人本地
+用共享密钥算出票据即可。
+
+## 1. 已经上线的东西（主站侧）
+
+### 1.1 票据格式
+
+```
+v1.<签发时间的 Unix 秒级时间戳>.<HMAC-SHA256 十六进制小写>
+```
+
+签名原文为 `v1.<时间戳>`（固定前缀 `v1.` 加时间戳本身），密钥为共享密钥的 UTF-8 字节。
+等价于 `hex(HMAC_SHA256(key, "v1." + timestamp))`。
+
+### 1.2 校验规则
+
+- 必须恰好三段，第一段必须是 `v1`；
+- 签名比较用常量时间（`MessageDigest.isEqual`）；
+- 时间戳只接受 `[now - 300s, now]`，**未来时间戳一律拒绝**（防伪造者用远期时间换长期有效）；
+- 窗口内**允许重放**（用户明确接受），过期即失效；
+- 默认 300 秒有效期，可用 `personal.login.ticket-ttl-seconds` 调整，下限 30 秒。
+
+### 1.3 端点
+
+| 端点 | 作用 |
+| --- | --- |
+| `GET /login?t=<票据>` | 校验票据 → 作废旧会话（防会话固定）→ 建新会话 → 302 跳 `/index`；失败 302 跳 `/denied` |
+| `GET /login/logout` | 销毁会话 → 302 跳 `/denied` |
+| `GET /denied` | 静态提示页：「请在机器人里发送 `/login`」 |
+
+nginx 无需改动：`location /` 会把 `/login` 改写成后端 `/personal/login`。
+
+### 1.4 会话与鉴权
+
+- 登录成功下发 `JSESSIONID`，参数为 `Path=/`、`HttpOnly`、`SameSite=Lax`，14 天滑动过期。
+  **`Path=/` 是必须的**：nginx 会把 `/user` 改写成后端 `/personal/user`，若沿用容器按
+  请求路径推导的 `/personal`，浏览器判定 `/user` 不匹配就不会带会话，面板会一直 401。
+- `PersonalInterceptor` 放行「有效会话 **或** `AuthCode=alone`」，两者都拒绝时返回 **401**。
+  `alone` 是留给下载器前端与存储节点 `/message2me` 推送的，本次**没有**退役它。
+
+### 1.5 密钥
+
+- 主站从环境变量 `PERSONAL_LOGIN_SECRET` 读取（`personal.login.secret`），
+  由 systemd drop-in `/etc/systemd/system/lionwebsite.service.d/login-secret.conf`
+  加载 `/etc/lionwebsite/login-secret.env`（`600` 权限，不在仓库里）。
+- 密钥为空时**一律拒绝**票据，不会退化成放行。
+- 轮换方式：改两侧配置并重启。轮换后旧票据在 300 秒内自然失效。
+
+## 2. 机器人侧待实施（host-vm103-debian-qq）
+
+### 2.1 生成票据
+
+密钥必须与主站一致。**已由主人批准写入 PersonalHub 保险库**，引用为
+`secret://services/service-lionwebsite/panel-login-secret`；机器人侧按既有秘密读取流程
+申请取值，不要写进仓库或聊天记录。Python 侧计算方式：
+
+```python
+import hashlib, hmac, time
+
+def lionwebsite_login_link(secret: str, base: str = "https://personal.lionwebsite.xyz") -> str:
+    stamp = str(int(time.time()))
+    signed = f"v1.{stamp}"
+    digest = hmac.new(secret.encode(), signed.encode(), hashlib.sha256).hexdigest()
+    return f"{base}/login?t=v1.{stamp}.{digest}"
+```
+
+Shell 等价写法（`openssl`）供人工验证用：
+
+```sh
+SIG=$(printf 'v1.%s' "$STAMP" | openssl dgst -sha256 -hmac "$SECRET" -hex | awk '{print $NF}')
+```
+
+### 2.2 命令接入（已实施：复用既有 `/login`）
+
+**复用既有 `/login`，不新建命令名；一条回复里同时给出两个登录链接。**
+
+实现方式（vm103 实际做法，比原计划更稳）：**机器人进程不持有密钥**。
+签发走保险库固定动作 `CollabSecretService.use_secret`，值只交给进程内签名函数，
+不返回、不落盘、不进日志；审计只记引用与动作名 `lionwebsite-login-link`。
+QQ 侧 `plugins/login.py` 只经内部令牌 POST `/internal/panel-login`，
+由 PersonalService 统一产出文案，因此 QQ 与 Telegram 不会漂移。
+
+- Telegram：`telegram_panel_login()` 的返回文案改为同时给出 PersonalHub 面板链接与
+  LionWebsite 面板链接，`TELEGRAM_COMMANDS` 里 `login` 的描述同步更新。
+- QQ（LionQQBot）：既有 `/login`（别名 `/登录`）返回同样两条链接，共用同一套生成逻辑。
+- PersonalHub 未完整配置（缺 password / session_secret / TOTP）时，现有逻辑会回一句
+  配置提示；此时**仍要发出 LionWebsite 链接**，不要让一条链接的失败带掉另一条。
+- 帮助菜单（Telegram `/help` 与 QQ 菜单）中 `/login` 的描述同步更新。
+- 文案不要写成「两条都只能用一次」：PersonalHub 链接是一次性的，
+  LionWebsite 票据是 300 秒窗口内可重放。
+
+示例文案：
+
+```
+已生成登录链接：
+
+· Personal Hub：[打开面板](< PersonalHub 链接 >)
+· LionWebsite：[打开面板](< LionWebsite 链接 >)
+
+两条链接 5 分钟内有效，请勿转发。
+```
+
+### 2.3 与 PersonalHub 现有 /login 的关系
+
+PersonalHub 的 `/login` 原本只签发**它自己面板**的票据
+（`OneTimePanelLoginTickets` + `/panel/telegram-login`）。改造时保留这条，
+再在同一回复里附加 LionWebsite 链接；两者的票据机制与有效期互不影响。
+
+## 3. 交付与复验
+
+- 机器人侧提交状态：**两个机器人仓库的改动尚未提交 Git**（`v103` 侧待主人确认后
+  按项目约定提交，注意 PersonalHub 工作区另有前一轮未提交改动，勿混提）。
+- `us9929main-chatgpt` 的独立复验（2026-09-21）：
+  - 票据边界实测：`now` 与 `now-290s` 放行，`now-301s`、`now-400s`、`now+60s` 均落 `/denied`；
+    篡改签名与畸形串同样落 `/denied`。
+  - 密钥明文扫描：抓取两个任务目录全部正文与线程消息共 17 KiB，未出现密钥明文，
+    只有 4 处 `secret://` 引用。
+  - 内部接口鉴权：`POST /internal/panel-login` 无令牌与错令牌均返回 403。
+  - PersonalHub `/health` 返回 200；共享盘 waiting 指针已消费，队列已清空。
+
+## 4. 可选收尾（未做，需要时另开任务）
+
+- 移动端 `PrivateMainForMobile` 仍写死 `authCode: "alone"`。后端两种方式都接受，
+  所以它能用；要一并切到会话，照搬 `PrivateMain/src/store/index.js` 的改法即可。
+- `sourcecode/storageNode` 有两处硬编码 `alone`（`CustomUtil.java` 的 `/message2me`
+  与 `MultiThreadedHTTPServer.java` 的本机鉴权），属另一仓库，需单独发布后才能退役字面量。
+- 概览页的「本机订阅」链接 `https://personal.lionwebsite.xyz/sub/self` 目前是 404，
+  后端没有对应映射，属历史遗留，与本次登录改造无关。

+三、核心功能模块
+──────────────────────────────────────────────────────────────────────────────
+
+1. E-Hentai 画廊下载管理
+   - 用户通过 AuthCode 提交 E-Hentai 画廊链接，指定目标分辨率
+   - GalleryUtil 解析页面 (Jsoup) 获取: 名称/语言/页数/文件大小/可选分辨率
+   - 通过 Netty TCP 将下载任务发往远程存储节点 (RemoteService)
+   - RemoteService 维护与存储节点的长连接 (自动重连+端口探测)
+   - 存储节点实时回传下载进度 (DownloadStatusMessage)，通过 WebSocket 推送给前端
+   - 支持图片在线预览: 缓存 MPV key → 按需下载单页 → 转为 AVIF 格式
+   - 画廊收藏/取消收藏
+
+2. 个人管理服务
+   - 手动触发订阅更新，返回最近更新时间与已记录的家庭 IP
+   - 管理员留言经 PushService 转发到 Telegram
+
+   （文件浏览/上传/下载/分享/压缩/删除已在 td-20260921-a1b2c3 中整体下线）
+
+3. E-Hentai 搜索代理
+   - 代理搜索 exhentai.org，返回格式化结果 (含缩略图 URL)
+   - 缩略图代理: 下载 → ImageMagick 转 AVIF → 本地缓存 → 返回
+
+4. 代理订阅管理
+   - 定时从外部链接拉取 V2Ray/Clash 订阅配置
+   - 过滤高倍率节点 (流量倍率 > 2)
+   - 为每个用户生成唯一订阅 Key，记录更新 IP/UA/时间/位置
+
+5. Telegram 通知
+   - 通过 Telegram Bot 向 admin 推送: 任务提交/完成/失败、存储节点上下线、
+     Cookie 过期、订阅异常等
+
+四、定时任务 (@Scheduled)
+──────────────────────────────────────────────────────────────────────────────
+- 每 30 分钟: 检测存储节点连接，断开则自动重连
+- 每周一 4:00: 重置每周下载额度
+- 每天 0:00: 验证 E-Hentai Cookie 有效性
+- 每 24 小时: 更新代理订阅配置文件
+- 每周一 4:00: 清理缩略图缓存 (保留最近 10000 个)
+
+五、安全机制
+──────────────────────────────────────────────────────────────────────────────
+- 所有管理接口需 AuthCode 参数 (TaskHandlerInterceptor 校验)
+- /personal 和 /remote 路径限 AuthCode="alone" 用户
+- HumanInterceptor 拒绝无 User-Agent 请求
+- AdaptorFilter 记录所有请求日志 (IP/路径/UA/时间)
+
+六、依赖
+──────────────────────────────────────────────────────────────────────────────
