chore(gui): 版本号 3.0.2（合规清理：移除私有协议适配器与渠道插件）

G-Star 合规要求下，把"模拟官方客户端、复刻私有协议、自动领取平台额度"这一类
能力整体移出仓库。这些实现依赖各平台未公开的端点、签名算法与官方 client id，
属于绕过客户端校验获取额度，风险高于普通协议适配。

移除（93 个文件）：
- 适配器：opencodezen（伪装 UA 取免费池）、trae、buddy、kimicode
- 插件：channels.lua（12 个平台登录/领额度/签到）、quota.lua（厂商额度探针）
- 随之删除的 78 个渠道/额度专用测试与 3 份渠道文档

同时修掉的既有问题：
- **硬编码第三方 OAuth client_secret**（Google Cloud Code 的 GOCSPX-…，两处）
  随 channels.lua 一起消失。
- `deploy.sh` 的 `sync_plugins` 整段删除：它仍按"内置插件是发行物"的旧前提
  把插件复制/覆盖进 plugin_dir，与"插件属运维资产、网关不安装不覆盖"的契约
  冲突。现在部署脚本只同步适配器与二进制/配置。
- 适配器清单去掉已移除项；e2e 配置改用显式 `auto:` 链（`models.priority` 早已
  移除，该测试此前已失效）。

保留（公开协议）：openai / anthropic / gemini / deepseek / github / groq /
mistral / ollama / qwen38 / sensenova = 10 个适配器；插件示例 billing / usage。

验证：go build -tags luajit ./... OK；internal/lua 21.4s、provider、core 51s、
gateway 122.8s、e2e 9.0s 全绿。

+# ModelRouter / llmsproxy 交接文档
+
+更新时间：2026-10-19
+工作目录：`/home/program/llmsproxy`
+当前分支：`release/v2.0.x`
+
+## 1. 当前 Git 状态
+
+最近提交：
+
+- `c9f3453 fix(codearts): 识别 InferHub 未注册模型`
+- `12bfd53 fix: 收口渠道源迁移与测试页合并`
+- `25970a2 refactor(scheduler)!: 移除 priority 废弃字段 + 一通道一源 + discover 复用凭据`
+
+`c9f3453` 已推送到 `origin/release/v2.0.x`。
+
+注意：当前工作树在最后一轮添加 provider 回归测试时出现了一个**未完成且可能无法编译的测试编辑**。最后一次工具报错：
+
+```text
+internal/provider/provider_test.go:99: missing ',' in argument list
+```
+
+下一位 agent 接手后的第一步必须是：
+
+```bash
+cd /home/program/llmsproxy
+git status --short
+gofmt -w internal/provider/provider_test.go 2>&1 || true
+go test -tags luajit ./internal/provider/ 2>&1
+```
+
+如果测试文件处于半编辑状态，先检查 `TestProviderChatStreamNormalizesStopAfterToolCall`，修正 Go 字符串转义或删除该未完成测试后再继续。不要直接部署当前工作树。
+
+## 2. 生产服务状态
+
+生产服务：`llmsproxy.service`
+
+- 当前服务 active
+- 监听：`0.0.0.0:8081`
+- 二进制已通过 `./deploy.sh` 原子替换并重启
+- 最近一次部署健康检查通过
+- 当前生产插件 SHA256 前缀曾核对为：`1bf26cbb3abcb107`
+- 当前生产二进制在最近部署后已更新
+
+不要把密钥写入交接记录。生产 admin key 保存在本机运维环境中，不应复制到聊天、文档或提交。
+
+## 3. Channel 源当前状态
+
+生产源已经从旧的“一账号一源”收口成“一渠道一源”：
+
+```text
+channels-trae
+channels-minimax
+channels-lobsterai
+channels-buddy
+channels-codearts
+channels-zcode
+```
+
+旧形态源已经清理：
+
+```text
+channels-<provider>-<account_id>
+```
+
+此前旧源和新源并存，造成同一渠道同一模型出现多份，只能靠账号 hex 区分。
+
+根因已修复：内核 `list_sources` 返回裸数组，但旧插件代码按 `{sources = [...]}` 信封读取，导致迁移清理循环永远为空。当前 `channels.lua` 已兼容：
+
+- 裸数组
+- `{sources = [...]}`
+- `{json = {sources = [...]}}`
+
+相关代码：
+
+```text
+internal/lua/plugins/channels.lua: syncProviderSource
+internal/core/channels_legacy_source_cleanup_test.go
+```
+
+当前生产源列表已实测只有 6 个新形态源。
+
+## 4. CodeArts 当前状态
+
+### 已确认可用的部分
+
+CodeArts 使用：
+
+```text
+adapter = codearts
+base_url = https://snap-access.cn-north-4.myhuaweicloud.com
+```
+
+CodeArts 的 chat 请求需要完整 AK/SK/security token 凭据，由插件适配器签名，不是裸 Bearer token。
+
+真实流式工具调用测试已经成功：
+
+请求形状：
+
+```json
+{
+  "model": "channels-codearts:openpangu-2.0-flash",
+  "messages": [{"role": "user", "content": "Use the weather tool for Beijing."}],
+  "tools": [{
+    "type": "function",
+    "function": {
+      "name": "get_weather",
+      "description": "Get weather",
+      "parameters": {
+        "type": "object",
+        "properties": {"city": {"type": "string"}},
+        "required": ["city"]
+      }
+    }
+  }],
+  "tool_choice": "auto",
+  "stream": true,
+  "max_tokens": 64
+}
+```
+
+结果：
+
+- HTTP 200
+- `Content-Type: text/event-stream`
+- 返回结构化 `tool_calls`
+- 函数名 `get_weather`
+- 参数最终为 `{"city":"Beijing"}`
+- `finish_reason = tool_calls`
+
+因此 CodeArts 的流式工具调用链路当前是通的。
+
+### CodeArts 模型刷新
+
+生产调用：
+
+```http
+POST /api/plugins/http/channels/model/refresh
+{"platform":"codearts"}
+```
+
+实测返回：
+
+```json
+{
+  "ok": true,
+  "results": [
+    {"platform": "codearts", "ok": true, "count": 11}
+  ]
+}
+```
+
+CodeArts 模型目录来自两个签名端点并合并：
+
+1. `opengw.developer.huaweicloud.com/api/v1/gateway/config`
+   - `result.models`
+2. `snap-access.cn-north-4.myhuaweicloud.com/v1/model/builtin`
+   - `builtinModels`
+
+相关解析：
+
+```text
+internal/lua/plugins/channels.lua: parseRemoteModels
+internal/lua/plugins/channels.lua: refreshRemoteModels
+internal/core/channels_codearts_catalog_test.go
+```
+
+### 已确认失效并禁用的 CodeArts 模型
+
+下面 4 个模型曾收到明确的上游 404：
+
+```text
+CodeArts-Pangu
+deepseek-v4-flash-0731
+deepseek-v4-pro-0813
+glm-5.3-flash
+```
+
+生产上已通过 `channels/model/set_disabled` 禁用。它们仍可能在 `model/list` 中出现，但 `disabled=true`，不会作为可用模型路由。
+
+新增的死模型判据：
+
+```lua
+model is not registered
+```
+
+对应提交：`c9f3453`。
+
+注意：当前插件的 dead-model 机制只在收到真实请求失败后记录模型；刷新目录不会自动根据“远端目录没有该模型”删除模型，这是刻意设计，避免误删远端目录不完整的平台模型。
+
+CodeArts 当前仍有一些模型返回 429/TPM 限流，例如：
+
+```text
+deepseek-v4-flash
+deepseek-v4.1-flash
+```
+
+429 不是模型失效，不能禁用。
+
+## 5. 其他 Channel 实测结果
+
+### Trae
+
+真实流式 + tools 请求：
+
+```text
+channels-trae:DeepSeek-V4-Flash
+```
+
+结果：
+
+- HTTP 200
+- SSE 正常返回
+- 结构化 tool call 返回
+- 但上游最后的结束原因可能是 `stop`，即使前面已经出现 tool-call fragments
+
+这会让 Agent 把工具调用误判成普通文本完成。
+
+当前准备中的修复在统一 provider 流式层：
+
+```text
+internal/provider/provider.go
+```
+
+逻辑是：只要本次流出现真实 tool-call 片段，后续 `FinishReason == "stop"` 就归一成 `tool_calls`。
+
+另外，Trae 的非流式接口偶尔返回 SSE。当前 `trae.lua` 对非流式 SSE 只取最后一条 data，不能完整合并多条工具调用/推理片段。这是后续仍需处理的协议问题，但不能用非流式手工请求结果推断 Pi 的真实请求模式。
+
+### Buddy
+
+真实流式 + tools 请求：
+
+```text
+channels-buddy:glm-5.3-flash
+```
+
+结果：
+
+- HTTP 200
+- SSE 正常返回
+- tool-call 参数分片可见
+- 最终有 `finish_reason = tool_calls`
+- 但某些上游 chunk 的 `tool_calls` 可能是空对象 `{}`
+
+空对象不是合法的 OpenAI tool-call 数组，部分 Agent 客户端会拒绝。
+
+当前准备中的修复在：
+
+```text
+internal/lua/adapters/buddy.lua
+```
+
+只在 `type(delta.tool_calls) == "table" and #delta.tool_calls > 0` 时输出 `tool_calls`，避免 Lua 空表被编码为 `{}`。
+
+Buddy 的非流式错误：
+
+```text
+11101: Non-stream chat request is currently not supported
+```
+
+之前出现的该错误来自手工 `curl` 测试中显式设置 `stream:false`，不能归因到 Pi。真实 `stream:true + tools` 已经证明 Buddy 流式工具调用可以工作。
+
+### MiniMax
+
+生产日志反复出现：
+
+```text
+adapter "anthropic": status=401 body={"error":"invalid access token"}
+provider channels-minimax: api error 401
+```
+
+这是凭据失效问题，不是 tools 形状问题。
+
+当前源：
+
+```text
+channels-minimax
+adapter = anthropic
+endpoint = /mavis/api/v1/llm/v1/messages
+```
+
+需要用户重新登录/提供有效凭据。不要擅自刷新一次性 refresh token，之前已经发生过 refresh token 被消耗后无法再次使用的事故。
+
+## 6. 当前未提交的代码改动
+
+最后一轮已经改动但尚未完成提交：
+
+```text
+internal/provider/provider.go
+internal/lua/adapters/trae.lua
+internal/lua/adapters/buddy.lua
+internal/provider/provider_test.go  # 可能有半编辑、需先修复
+```
+
+已完成的意图：
+
+1. provider 流式层记录 `sawToolCalls`
+2. 看到真实 tool-call 后，把后续 `stop` 归一为 `tool_calls`
+3. Trae 不输出空工具调用表
+4. Buddy 不输出空工具调用表
+5. provider 回归测试模拟“tool fragment + stop”场景
+
+但 provider 测试最后一次编辑工具报错：
+
+```text
+internal/provider/provider_test.go:99: missing ',' in argument list
+```
+
+因此必须先修测试文件，再提交。
+
+## 7. 推荐接手顺序
+
+### 第一步：修复工作树
+
+```bash
+cd /home/program/llmsproxy
+git status --short
+sed -n '1,150p' internal/provider/provider_test.go
+gofmt -w internal/provider/provider_test.go 2>&1 || true
+go test -tags luajit ./internal/provider/ 2>&1
+```
+
+若测试函数字符串转义难以修复，先删除半成品测试，再重新用 raw string 写测试。
+
+### 第二步：跑定向验证
+
+```bash
+luac -p internal/lua/adapters/trae.lua
+luac -p internal/lua/adapters/buddy.lua
+go test -tags luajit ./internal/provider/
+go test -tags luajit ./internal/lua/ -run 'Adapter|Buddy|Trae|Stream'
+```
+
+### 第三步：构建并部署临时验证版
+
+修复确认后：
+
+```bash
+go build ./...
+./deploy.sh
+```
+
+部署前确认：
+
+```bash
+sha256sum internal/lua/plugins/channels.lua
+sha256sum /etc/llmsproxy/plugins/channels.lua
+systemctl is-active llmsproxy
+```
+
+### 第四步：真实流式回归
+
+不要用 `stream:false` 测试流式问题。使用：
+
+```bash
+KEY='<从本机安全环境读取，不写入文档>'
+TOOL='{"type":"function","function":{"name":"get_weather","description":"Get weather","parameters":{"type":"object","properties":{"city":{"type":"string"}},"required":["city"]}}}'
+
+curl --no-buffer --max-time 90 \
+  -H "Authorization: Bearer $KEY" \
+  -H 'Content-Type: application/json' \
+  -d "{\"model\":\"channels-codearts:openpangu-2.0-flash\",\"messages\":[{\"role\":\"user\",\"content\":\"Use the weather tool for Beijing.\"}],\"tools\":[$TOOL],\"tool_choice\":\"auto\",\"stream\":true,\"max_tokens\":64}" \
+  http://127.0.0.1:8081/v1/chat/completions
+```
+
+分别将 model 替换为：
+
+```text
+channels-codearts:openpangu-2.0-flash
+channels-trae:DeepSeek-V4-Flash
+channels-buddy:glm-5.3-flash
+```
+
+验收：
+
+- HTTP 200
+- `Content-Type: text/event-stream`
+- 不能出现 `tool_calls: {}`
+- 有 tool-call fragments 时最终必须是 `finish_reason: tool_calls`
+- CodeArts 当前应继续返回结构化工具调用
+
+### 第五步：CodeArts 刷新验收
+
+```bash
+curl -sS -X POST \
+  -H "Authorization: Bearer $KEY" \
+  -H 'Content-Type: application/json' \
+  -d '{"platform":"codearts"}' \
+  http://127.0.0.1:8081/api/plugins/http/channels/model/refresh
+```
+
+预期：
+
+```json
+{"ok":true,"results":[{"platform":"codearts","ok":true,"count":11}]}
+```
+
+再检查：
+
+```bash
+curl -sS -X POST \
+  -H "Authorization: Bearer $KEY" \
+  -H 'Content-Type: application/json' \
+  -d '{"platform":"codearts"}' \
+  http://127.0.0.1:8081/api/plugins/http/channels/model/list
+```
+
+预期：远端目录 11 个 + 兜底补位，已确认 404 的 4 个仍保持 `disabled=true`。
+
+## 8. 发布/安装包状态
+
+目前没有完成“全部安装包”发布闭环。
+
+已经发生的事情：
+
+- 核心包构建成功，但脚本实际使用了 `git describe`，产物版本类似：
+  `2.0.40~4-gc9f3453`
+- Linux GUI 包构建成功，版本为 `1.9.7`
+- Windows 主机 Wine 构建失败，生成了一个 264KB 的坏 `ModelRouter Setup 1.9.7.exe`，绝对不能发布
+- Docker Windows 构建也失败在拉取 Docker Hub 基础镜像 `golang:1.25` 网络超时
+- apt 无法找到 `wine32:i386`
+- 旧的 1.9.5/1.9.6 Windows 包是历史产物，不能作为当前版本
+
+不要把旧 Windows exe 当作新包发布。
+
+仓库已有 Docker 方案：
+
+```text
+cmd/gui/scripts/dist-win-docker.sh
+cmd/gui/docker/win-builder/Dockerfile
+```
+
+但当前 Docker Hub 网络不可用。若要继续做 Windows 包：
+
+1. 在可访问 Docker Hub 的构建机/CI 执行 Docker 方案；或
+2. 提供包含 Wine32/Wine64 的完整构建环境；或
+3. 暂时只发布 Linux/core 包，并明确说明 Windows 包未完成。
+
+版本脚本注意：
+
+- 核心包脚本使用位置参数：
+
+  ```bash
+  ./packaging/core-dist.sh 2.0.41
+  ```
+
+  不是 `VERSION=2.0.41 ./packaging/core-dist.sh`。
+- GUI 版本来自 `cmd/gui/package.json`，环境变量 `VERSION` 不会自动修改 Electron 产品版本。
+- 清理旧产物后再打包，并在全部包完成后统一计算 `SHA256SUMS`。
+
+## 9. 参考插件状态
+
+用户要求按：
+
+```text
+https://github.com/Ebony-Vinyl/dsh-our-free-model
+```
+
+逐厂商对照参考插件。
+
+当前本地路径：
+
+```text
+/tmp/pi-github-repos/Ebony-Vinyl/dsh-our-free-model
+```
+
+但该目录当前不是有效可读源码副本：
+
+- `vendor/channel-pack/src` 下面只有空目录；
+- `.git` 没有有效 `HEAD`/refs；
+- 无法从本地 Git 对象恢复源码；
+- 本地也没有 `buddy.ts`、`trae.ts`、`codearts.ts` 等文件。
+
+因此不能声称当前适配器是逐行照参考插件移植的。若要继续按用户要求完成，必须先重新 clone/恢复该 GitHub 仓库源码，确认以下文件实际存在后再对照：
+
+```text
+vendor/channel-pack/src/trae.ts
+vendor/channel-pack/src/buddy.ts
+vendor/channel-pack/src/codearts.ts
+vendor/channel-pack/src/*adapter*
+vendor/channel-pack/src/*model*
+```
+
+当前仓库代码只能作为临时协议修复基础，不能代替参考插件源码。
+
+## 10. 关键结论
+
+- Pi 是否发送流式请求，历史日志没有保存入站 `stream/tools` 字段，不能靠旧日志判断。
+- 本次真实 `stream:true + tools` 测试证明 ModelRouter 流式路径能工作：
+  - CodeArts：通过；
+  - Trae：通过但结束原因需归一；
+  - Buddy：通过但需过滤空 `{}`；
+  - MiniMax：凭据 401，独立问题。
+- 不要再用 `stream:false` 的手工请求推断 Pi 的问题。
+- CodeArts 刷新接口当前真实返回 `ok=true,count=11`，刷新链路不是当前阻塞点。
+- 当前最紧急的代码状态是修复 `provider_test.go` 的半编辑，然后验证未提交的统一流式修复。
+- 未经测试、未重新构建、未重新部署，不要继续改生产账号或刷新一次性凭据。

-## 核心优势
+## 核心能力
 
-### 极致轻量
-
-- **单二进制**：编译后 8~12MB（`-s -w` strip 后约 8MB），零运行时依赖（仅依赖系统 libc），部署即用
-- **低内存占用**：与源数量相关，非与运行时长相关——单源 ~10MB、16 源生产实例 ~32–35MB（[实测分解与调优](#内存占用实测与调优)）
-- **日志按需加载**：统计数字来自**全量**审计日志（启动时流式扫一遍即释放，29MB/22 万行约 260ms），但原始记录不常驻内存——默认只加载首屏，下滚自动分页，CSV 导出流式写出（O(1) 内存），离页即释放
-- **零运行时依赖**：纯 Go + LuaJIT 静态链接，无需安装 Python/Node/Java 等运行时
-- **启动极快**：冷启动 < 200ms，热重载配置 < 10ms
-
-### 强大的多租户调度能力
-
-- **多密钥多租户**：支持无限密钥，每个密钥独立角色、模型范围、Token 配额、重置周期
-- **按模型配额**：每把 key 的每个模型单独配 token + 请求数配额与重置周期（小时/周/月/自定义 N 小时）；一个模型用满只影响该模型，同 key 其它模型照常；耗尽返 429 + `Retry-After` 并点名模型，admin key 永不受限
-- **AUTO 智能调度**：基于优先级档位的分级调度，同优先级源自动轮询负载均衡，故障自动毫秒级故障转移
-- **自愈冷却**：冷却上限 5 分钟，过半后放行 1 个探测请求，上游/额度恢复即刻回归轮询，无需等满冷却窗口
-- **Token 配额管理**：精确到模型级别的 Token 配额控制，支持小时/周/月/自定义小时周期自动重置
-- **同优先级源负载均衡**：同一优先级档位的多个源，请求自动 Round-Robin 均匀分发，故障毫秒级故障转移
-- **Source-Model 前缀路由**：支持 `source-model`/`source:model`/`source/model` 精确指定上游源
-
-### 生产级可靠性
-
-- **热加载配置**：WebUI 修改源/密钥/适配器/AUTO链即时生效，无需重启
-- **密钥加密落盘**：AES-256-GCM 加密存储 `api_key`、网关密钥、请求头，master.key 0600 权限保护
-- **实时源探测**：`GET {base}/models` 定期探测，毫秒级感知上游状态，不污染调度退避状态
-- **全链路审计**：HTTP 访问日志、登录/配置变更审计、请求记录 CSV 导出、密钥用量统计 CSV 导出
-
-### 灵活的协议适配
-
-- **LuaJIT VM**：每个适配器独立 VM + **弹性 worker 池**（按需扩缩容，空闲时自动回收），安全并发，Lua 脚本热加载无需重启
-- **Lua 适配器协议**：`transform_request` / `transform_response` / `transform_stream_chunk` 双向转换
-- **动态请求头钩子**：`build_headers(meta)` 支持 HMAC 签名、动态 Header 注入
-- **多模态透传**：`image_url` 等多模态内容在多源间无损透传，Anthropic/Gemini/Ollama 自动转换
-
-## 实现
-
-统一 OpenAI 兼容网关：把多个上游 LLM 源（DeepSeek、Qijiar、OpenAI、Anthropic、Gemini、
-Groq、Mistral、Ollama、KimiCode…）通过 **Lua 适配器** 做协议转换，对内网暴露
-一个标准 `OpenAI Chat Completions` 接口（`/v1/chat/completions` + `/v1/models`），
-支持单次结算、SSE 流式、**AUTO 模型路由**与**多模态**透传。
-
-从 [HomeAgent](https://gitcode.com/JianFeeeee/HomeAgent) 的多源 LLM 适配层
-（`internal/agent/api/provider.go` + `internal/lua/adapters/*`）抽离而来并独立演进。
-
-## 特性
-
-- **多源**：一个进程内配置任意多个上游源，按请求的 `model` 自动路由。
-- **AUTO 模式**：`default_model: AUTO` 时按优先级页保存的 AUTO 链档位逐档调度并发请求。
-- **统一输出**：所有源对外都是 OpenAI 格式（含 `reasoning_content`、`tool_calls`、`usage`）。
-- **生图**：`POST /v1/images/generations`，`kind: image` 的模型独立路由。
-- **多模态**：`content` 数组（`image_url` 等）在多源间无损透传，Anthropic/Gemini/Ollama 自动转换。
-- **LuaJIT VM**：基于 golua 绑定的 LuaJIT，每个适配器独立 VM + worker 池，安全并发。
-  池是 **弹性** 的：`Σ max_concurrent` 只是上限而非预分配，状态按需创建、空闲时自动回收，
-  因此空载网关几乎不持有 Lua 状态（启动 0 个）。
-  - 扩容步长由适配器最大并发决定：`clamp(ceil(max/8), 1, 8)`，且仅在**真实并发争用**
-    （所有现有状态均已占用）时批量预热，顺序流量始终只用 1 个状态。
-  - 缩容步长由当前连接数决定：`clamp(ceil(冗余/(1+占用)), 1, 冗余)`——无连接时一轮收到
-    常驻下限，忙时每轮只释放 1 个，保护热路径。WebUI「适配器」页展示实时池指标。
-- **thinking 预算**：请求里的推理开关/预算归一为中立的 `thinking:{enabled,budget_tokens}`，
-  适配器映射到各自协议（Anthropic `thinking.budget_tokens`、Gemini `thinkingConfig`、
-  DeepSeek `thinking.type="disabled"`）。
-- **Lua 适配协议**：每个源挂一个 `.lua` 适配器，完成 `transform_request` /
-  `transform_response` / `transform_stream_chunk` 双向转换，协议差异全在 Lua 层。
-- **签名 / 请求头钩子**：适配器可定义 `build_headers(meta)`，在 Go 发 HTTP 前
-  动态注入/签名请求头——用于云端 API 校验调用方 app（如 KimiCode 只放行特定
-  agent）。提供 `hmac_sha256_hex` / `sha256_hex` / `base64_encode` 等签名辅助。
-- **WebUI**：内置管理界面，可在线查看/新增/编辑上游源与模型、配置 AUTO 优先级链、
-  管理密钥模型范围，写入运行时文件持久化。
-- **密钥加密存储**：运行时文件中的上游 `api_key`、自定义请求头值、网关 key 均以
-  AES-256-GCM 加密落盘（`master.key` 独立 0600，或 `LLMS_PROXY_MASTER_KEY`）。
-- **实时源探测**：状态页探测各源可达性（`GET {base}/models`，失败回退最小请求），
-  不污染正常调度的退避状态，错误信息在 UI 可悬停查看。
-- **鉴权**：网关自身用 `gateway_keys` 校验客户端 Bearer key；与上游各自的 key 相互独立。
-- **流式**：SSE `chat.completion.chunk`，含角色首包与 `[DONE]` 收尾。
-- **全链路审计**：HTTP 访问日志、登录/配置变更审计、请求记录 CSV 导出、密钥用量统计 CSV 导出
-- **AES-256-GCM 加密存储**：运行时文件敏感字段加密落盘，master.key 0600 权限，支持环境变量注入主密钥

 ```
 
-WebUI 源编辑框里也有「自动探测模型」按钮：填好 URL 和 key 点一下，列表自动
-填好，仍需点保存才生效。
-
-几点值得知道：
-
-- **URL 形态不用猜。** 厂商对「`/v1` 放 base 还是放 path」没有共识，探测会
-  依次尝试若干候选并返回答对的那个，同时给出归一化后的 `base_url` +
-  `endpoint`（`endpoint` 平时留空，因为 openai adapter 自带 `/chat/completions`）。
-- **`image_endpoint` 是另一套规则。** 网关的图像默认路径是**绝对**的
-  `/v1/images/generations`，而 chat 默认是相对的。所以 `base_url` 带 `/v1` 时
-  必须显式给 `image_endpoint: /images/generations`，否则图像请求 404。
-  探测会替你填好。
-- **图像模型只看上游自己声明的 modality**，绝不从模型名猜。`gpt-image-2`
-  这类 id 也出现在同时提供对话服务的目录上，猜错会让 AUTO 链选中一个只支持
-  图像生成的模型，其后每一层都被它拖垮。
-- **不会逐模型探活。** 34 个模型的目录跑一轮要花钱且耗时数分钟，`/models`
-  是足够便宜的信号；模型是否真能应答留给正常请求去发现。
-- **对已存在的源，必须显式 `replace_models: true`** 才会覆盖模型列表。重新
-  探测顺手抹掉为 AUTO 链手工调过的 priority，是最难排查的一类数据丢失。
-- **`api_key` 留空表示沿用已存值**，不会把凭据清空。
-
-
-`config.yaml`、`runtime.json`、`master.key`、`adapters/` 均不提交版本库（见
-`.gitignore`），请随备份带走——`master.key` 丢失后运行时密文无法解密。
-
-运行文件生成在 `-config` 所在目录：`adapter_dir` / `runtime_file` 自动指向
-配置文件旁边的 `adapters/` 与 `runtime.json`，从任意工作目录启动都可用。
-
-运行时文件（`runtime_file`）中的敏感字段自动加密：
-
-- 加密算法 AES-256-GCM，格式 `enc:v1:<base64>`。
-- 主密钥来源：环境变量 `LLMS_PROXY_MASTER_KEY`（64 位 hex）；否则读取
-  `runtime_file` 同目录的 `master.key`；都不存在时首次启动自动生成 `master.key`（0600）。
-- 升级时旧明文文件自动兼容：首次运行正常读取，任何 UI 保存操作触发全文件加密迁移。
-- 注意：**master.key 丢失后密文无法解密**，请随配置一起备份；切勿提交到版本库。
-
-### 网关密钥（多密钥）
-
-网关鉴权采用「多密钥 + 角色 + 模型范围」架构，密钥持久化在 `runtime_file` 的
-`keys` 字段（加密存储）：
-
-- `gateway_keys` 配置只是**初始 admin 密钥种子**：首次启动迁移为运行时 admin
-  key，之后不再参与鉴权管理。
-- **重要：首次启动后请在 WebUI「密钥」页更换管理员密钥**——初始密钥明文写在
-  `config.yaml` 里（每次安装随机生成），继续使用存在被盗风险；用新密钥登录后删除初始密钥。
-- WebUI **密钥页**可创建/删除密钥；每个密钥可指定 `admin`（管理全部）或
-  `user`（仅看自己的 key）角色，并配置**模型范围**（模型 + 源 + token 配额 +
-  重置周期）。
-- 客户端用任意一个已授权的密钥明文作为 Bearer（`Authorization: Bearer <key>`）。
-- 删除密钥即从运行时存储移除，立即失效。
-
-#### 密钥用量配额
-
-**配额按模型单独设置**：每个密钥的 `models[]` 里，每一条模型范围各自带一份
-token 配额与请求数配额。一个模型用满只影响该模型，同一密钥的其它模型照常工作。
-
-```yaml
-keys:
-  - key: sk-gw-<hex>
-    role: user
-    name: agent-alice
-    models:
-      - model: deepseek-v4-flash
-        token_quota: 1000000   # 本周期内该 key 用这个模型的 token 预算
-        req_quota: 20000       # 本周期内的请求次数
-        period: nhour          # "" | hour | week | month | nhour
-        hours: 6               # 仅 nhour
-      - model: AUTO
-        token_quota: 5000000   # AUTO 也是一条独立配额
-        period: day            # ← 这种写法会被拒绝（词表只有 hour/week/month/nhour）
-      - model: kimi-k3        # 未列配额 = 无限
-```
-
-- **没有「整钥总配额」**：这是刻意的设计。整钥总额会让「把 A 模型的额度挪给
-  B 模型」变成一次全局重分配；按模型独立计费则每个模型各自可控，运维可以
-  看出哪个模型吃掉了预算。
-- `period` 词表：空 = 永不过期（累计总量），`hour` / `week` / `month` = 固定窗口，
-  `nhour` + `hours` = 自定义小时数。**拼错的周期在写入时就被拒**，不会静默变成
-  永不过期。
-- 配额严格按密钥隔离，且**同一密钥内按模型隔离**：A 密钥用满 `m1` 不会消耗
-  B 密钥的额度，同一密钥的 `m2` 也不受影响。
-- 配额统计含聊天、流式、生图，跨重启从审计日志回放（保留 40 天，覆盖最长的
-  month 窗口）。
-- 配额耗尽返回 **429 + `Retry-After`**（`rate_limit_exceeded`），消息里点名是哪个
-  模型用满了，客户端可等窗口重置后自动恢复；模型越权才是 403。
-  **admin 密钥永不受配额限制**（其 scope 上的配额也不强制），避免把管理员
-  锁在门外。
-- 窗口用量按整点小时分桶统计，实际释放比配置窗口最多晚 1 小时（配额宁可晚释放
-  也不超发）。
-- `PUT /api/keys/{key}` 提交 `models` 即同时提交它们的配额（配额就是 scope 的一部分，
-  不存在会与模型列表脱节的第二份预算）。显式 `0` = 解除该模型的限制。
-
-##### 配额拒绝 vs 容量拒绝：两种「拒绝」含义不同
-
-配额在**入口**检查，不占用任何上游槽位，因此是廉价拒绝；容量不足则要走
-`busyWait` 有界等待后才返回 503。实测（容量 8、0.6s/请求、100 并发）：
-
-| 情况 | 状态码 | 延迟 | 是否打到上游 |
-|---|---|---|---|
-| 配额用尽（`req_quota` 50 → 100 并发） | `429 rate_limit_exceeded` + `Retry-After` | **19–21ms** | 否 |
-| 容量打满（同一拓扑，未限配额） | `503 upstream_error` | ~2.6s（`busyWait`） | 超出部分否 |
-
-客户端因此可以区分「等窗口重置」与「等上游腾出容量」：前者只需等待，后者
-通常该降并发或换源。
-
-##### 配额的开销
-
-配额桶按 (密钥, 模型, 整点小时) 分桶保留 40 天，实测（AMD 7840HS）：
-
-- 窗口查询按窗口长度而非保留总量扫描：1h 窗口 49ns、24h 窗口 55ns、
-  30d 窗口 3.9μs（此前全扫保留总量，960 桶时 5.9μs）。
-- 记录一条请求：283ns、3 分配（与引入配额前相同，分配来自 ring buffer）。
-- 内存：生产形态（7 密钥 × 8 模型 × 2 源 × 满 40 天 retention）约 **3.7MB**。
-  按源 pin 的 `source::model` 桶**惰性创建**——只有当某条配额真的 pin 了
-  某个源时才维护，否则每条记录多写一份桶，在 20 密钥 × 8 模型 × 3 源下会
-  多占 18MB。
-  代价：配置 pinned 配额之前的历史用量无法事后按源拆分，所以 **pinned 配额的
-  首个窗口可能少算**。
-
-```bash
-# 配额耗尽时客户端看到（点名了具体模型）
-HTTP/1.1 429 Too Many Requests
-Retry-After: 2100
-{"error":{"type":"rate_limit_exceeded","message":"token quota exceeded for \"deepseek-v4-flash\" (5000000/5000000)"}}
-```
-
-### 模型路由
-
-`/v1/chat/completions` 的 `model` 解析顺序：
-
-1. `source/model` 或 `source:model` 前缀 → 指定源；
-2. 精确匹配某个源的 `model`；
-3. 配置 `default_model: AUTO` 时 → 走优先级页保存的 AUTO 链（见下）；
-4. 否则回落（返回错误）。
-
-任何 OpenAI 客户端，只要 `model` 设为某个源的 `name/任意名`，即可锁定走该源；
-设为 `AUTO`（或网关配了 `default_model: AUTO`）即自动按优先级链选源。
-
-### AUTO 链（优先级页）
-
-AUTO 调度**只**由优先级页保存的规则决定，源配置里的 `models[].priority` 数字不再
-参与调度、也不再显示。**聊天与生图是两套独立的链**，在优先级页面通过「聊天 / 生图」
-按钮切换编辑：
-
-- **聊天链**（`runtime_file` 的 `auto` 字段）：服务 `POST /v1/chat/completions`
-  的 `model: AUTO` 请求；只接受 `kind: chat` 模型，配置在链里的生图槽位会被忽略。
-- **生图链**（`runtime_file` 的 `auto_image` 字段）：服务 `POST /v1/images/generations`
-  的 `model: AUTO` 请求；只接受 `kind: image` 模型。未配置生图链时，AUTO 生图回落
-  到「所有含生图模型的源、按注册顺序」的旧行为，兼容旧配置。
-
-每条规则 = 一个「槽位」：`{ model, source, tier, token_quota, period, hours }`。
-
-- `tier` 表示优先级档位：同一档的模型并排、共享该优先级；档位从上到下递减。
-- 同一模型可配置多个槽位（如 A 源低配 → B 源低配 → A 源高配 → B 源高配），按档位顺延。
-- `token_quota` > 0 时该槽位在重置周期内用满即顺延到下一槽位；`period` 支持
-  `hour` / `week` / `month` / `nhour`（配合 `hours`），空 = 不限。
-- 同 tier 内按「偏好分」排序，失败槽位冷却后自动跳过；冷却 / 配额耗尽 / hard
-  错误会顺延到下一 tier，全部失败时返回 503 并附上每档失败摘要。
-
-### 冷却与半冷却探测（自愈调度）
-
-槽位失败后进入指数退避冷却（5s → 10s → 20s …，上限 **5 分钟**）。冷却不是全时段
-硬闸：
-
-- **前半段完全静默**：刚失败的槽位不接任何流量，避免对故障上游持续施压。
-- **后半段放行 1 个探测**：窗口过半后，同一 `(源, 模型)` 最多允许 **一个** 请求作为
-  探测通过。探测槽数 = `clamp(max_concurrent / 10, 1, 2)`——`max_concurrent: 10`
-  的源恰好放行 1 个探测请求。
-- **探测排在最后**：同 tier 内探测候选永远排在健康候选之后，只有没有正常槽可用时
-  才承接真实流量，因此探测不会抢走可用容量。
-- **探测即真实请求**：成功则立即清零失败计数与冷却，槽位当场回到正常轮询——
-  上游恢复/额度恢复后不必等满整个冷却窗口。失败则重开一个新窗口，下次探测顺延到
-  新窗口的中点，不会连续重试。
-
-分类冷却策略：
-
-| 情况 | 冷却 | 说明 |
-|---|---|---|
-| 传输错误 / 5xx | 5s→10s→20s…，上限 5min | 指数退避 |
-| 401 / 403 凭据错误 | 10min | 换 key 后由下一次探测自动接回 |
-| 429 限流 | 30s 固定 | 「太快」不等于「坏了」，不进指数阶梯 |
-| 配额耗尽（`insufficient_quota` / `余额不足` 等） | 对齐配额窗口，上限 30min | **不进指数阶梯、不涨失败计数**，额度恢复即可用 |
-
-WebUI「优先级」页的槽位健康标签会区分 `冷却` / `待探测` / `探测中`，悬停可看窗口
-起点、探测放行时刻与完全恢复时刻。
-
-### 源（Source）与适配器（Adapter）的关系
-
-- **源** 是到某个上游的连接描述：`name`、`base_url`、`api_key`、模型列表与优先级。
-- **适配器** 是协议转换逻辑（Lua 脚本）：把统一 OpenAI 格式请求转成上游原生格式，
-  再把上游响应/流式分块转回统一格式。
-- 一个适配器可被多个源复用（如 `openai.lua` 同时服务多个 OpenAI 兼容站点）；
-  同一个源也可以切换不同适配器（改 `adapter` 字段即可）。
-- 源决定“连谁、暴露哪些模型”，适配器决定“怎么对话”——二者在 `sources[]` 条目中
-  通过 `adapter` 字段关联。
-
-加载流程（`internal/core` 的 `Core` 负责装配）：
-
-1. 启动时 `lua.NewVM(adapter_dir)` 加载全部适配器：内置适配器（编译期 embed）+
-   `adapter_dir` 下的同名覆盖文件；内置文件写在代码内，覆盖文件要求更高优先级。
-2. `config.Load` 读取 `config.yaml`，`config.NewStore(runtime_file)` 读 WebUI 改动的
-   运行时源，二者按名称合并成完整源列表。
-3. `rebuildRegistry` 为每个源创建 `provider.Provider`（持有目标适配器），并按源的
-   并发上限配置适配器 worker 池**上限**（不预分配，见下）。
-4. 请求进来时 `Registry` 按 `model` 路由到 Provider，Provider 调适配器
-   `transform_request` → HTTP 发送 → `transform_response` / `transform_stream_chunk`。
-
-WebUI 上的"新增/编辑源"、"上传 Lua 适配器"、"改 AUTO 优先级链"与"密钥模型范围"
-都即时生效（写入运行时文件或 `adapter_dir` 后重新装配，无需重启）；直接编辑
-`config.yaml` / `adapter_dir` 下的文件则需要重启进程才会重新加载。
-
-在 WebUI 删除源/适配器时：运行时（WebUI 创建）的源与 `.lua` 文件会真正移除；
-`config.yaml` 中定义的基源无法改写配置文件，采用删除标记隐藏（重启后仍隐藏），
-在 UI 里重新添加同名源即可恢复。
-
-### 源模板（多 key 负载均衡）
-
-多个上游 key 共享同一套配置（URL / 适配器 / 模型列表 / 并发 / rpm）时，逐一复制
-整段 source 太冗余。**源模板**保存除 `name` 和 `api_key` 以外的全部源字段，
-从模板一键创建多个仅 key 不同的源，天然支持多 key 负载均衡（每个展开源独立调度、
-独立冷却、独立健康状态）。
-
-- WebUI「源」页右上角「**模板管理**」按钮：列出全部模板，可编辑 / 删除 / 新建。
-- 添加源弹窗右上角两个按钮：
-  - **从模板创建** → 选模板 → 表单自动填充（name + key 仍需你填）；
-  - **存为模板** → 把当前表单非 key/name 字段存为新模板。
-- 模板持久化在 `runtime_file` 的 `source_templates` 字段，与运行时源一样热管理，
-  改完即时生效。模板本身不含密钥，可以安全共享 / 纳管。
-
-模板不会自己变成源——它只是「配方」。真正承担流量的是从模板创建出来的、带 key
-的具体源。
-
-### 内存占用（实测与调优）
-
-内存不是一个定数：它随**配置的源数量**增长（每个源一个 `http.Transport` 与连接池、
-一组健康状态），与运行时长无关。本机实测（Linux x86_64，12 核）：

-|---|---|---|
-| 1 源 / 1 适配器（最小配置） | ~4 MB | ~10 MB |
-| 1 源 + 29 MB 历史审计日志 | ~19 MB | ~20 MB |
-| **16 源 / 13 适配器 / 59 模型（本机生产）** | ~28 MB | **~32–35 MB** |
-
-> 历史参考：本项优化前同一生产配置为 **~105 MB**。降幅来自三处：审计日志的**原始记录**
-> 不再常驻内存（约 25 MB；统计聚合仍扫全量，但扫完即释放）、Lua 状态池不再单调增长、
-> 以及下面两个运行时开关。
-
-内存构成（生产实例分段测量，`/proc/<pid>/smaps`）：
-
-| 区域 | RSS | 说明 |
-|---|---|---|
-| Go 堆 | ~14 MB | provider/registry/scheduler 结构 + 连接池缓冲 |
-| 其他匹名（线程栈 / LuaJIT chunk / runtime） | ~12 MB | 与线程数、已加载适配器数相关 |
-| 二进制 text+rodata | ~8 MB | 映射的可执行文件页（只读、可被内核回收） |
-| Go runtime 预留 | ~4 MB | VSZ 上看到的 2 GB+ 是地址空间预留，不占物理内存 |
-| 共享库 | ~3 MB | libc / libluajit / libm |
-
-**两个推荐的部署开关**（只适用于环境变量，无需改代码）：
-
-```ini
-# /etc/systemd/system/llmsproxy.service
-Environment=GOGC=50
-Environment=MALLOC_ARENA_MAX=2
-```
-
-- `MALLOC_ARENA_MAX=2`：LuaJIT 的分配走 cgo → glibc malloc，glibc 默认允许 `8×nproc`
-  个 per-thread arena，每个碰到 malloc 的 OS 线程会占用一个（各约 1 MB，且**不归还给系统**）。
-  实测从 8–15 个 arena（约 7–12 MB）降到 **0**。
-- `GOGC=50`：把 Go 堆增长目标减半。**单独使用无效**（省下的堆会立即被更多 glibc
-  arena 吃掉，实测 20.3 → 21.5 MB 反而变大），必须与 `MALLOC_ARENA_MAX` 配合，
-  两者同时开启才降 **~19%**。网关是 I/O 密集型（本机 9 小时仅消耗 1min10s CPU），
-  多出的 GC 周期与它的空闲 CPU 相比可忽略。
-
-> 桌面版（Electron）已在 `cmd/gui/main.js` 里默认为内嵌核心注入这两个开关；手动 export 同名
-> 环境变量可覆盖。如果你用自己的 systemd unit / 容器，建议照上面加上。
-
-可选：`GOMEMLIMIT=48MiB` 作软上限，实测再省 ~1 MB；代价是逐近上限时 GC 转激进，
-温和场景不必开。
-
-### thinking 预算
-
-请求体带 `"thinking": {"enabled": false}` 时关闭推理；`"thinking": {"enabled": true,
-"budget_tokens": 4096}` 指定预算。内核只定义这个**中立**语义字段，映射到具体协议由
-适配器负责（Anthropic `thinking.budget_tokens`、Gemini `thinkingConfig.thinkingBudget`、
-DeepSeek `thinking.type = "disabled"`）。内核不再向适配器泄漏 `disable_thinking` /
-`extra_body` 这类私有字段。
-
-### WebUI
-
-内置管理界面（`GET /`），登录后可在浏览器完成：
-
-- **状态页**：源在线状态（实时探测 + 悬停看错误）、模型/源/key 用量统计、请求记录，
-  支持按时间范围导出 CSV；点击模型可生成 pin 到该模型的连接配置。
-- **对话页**：流式/非流式调试。
-- **密钥页**：创建/编辑网关 key，为每个 key 配模型范围（模型 + 源 + token 配额 + 周期），
-  管理员管理全部 key，用户只看到自己的 key。每个模型砖块显示自己的配额徽标
-  （如 `1.0K 77×·1h`，未设配额显示 `∞`），点开可编辑该模型的 token 配额、
-  请求数配额与重置周期 —— 配额按模型独立生效，一个用满不影响同一 key 的其它模型。
-  「我的密钥」页对用户展示本 key 的模型范围与各自配额。
-- **优先级页**：拖拽积木配置 AUTO 链档位。
-- **源页**：在线增删改上游源（API key 等敏感字段加密落盘）。
-- **适配器页**：上传 / 删除 Lua 适配器脚本。
-
-改动写入 `runtime_file`（重启仍生效）。
-
-## Lua 适配器协议
-
-完整 API 见 **[Lua 适配器 API 文档](docs/lua-adapters.md)**（[English](docs/lua-adapters-en.md)）。
-
-每个适配器是一个返回 table 的 Lua 脚本（`internal/lua/adapters/<name>.lua`），
-加载时可被 `adapter_dir` 下的同名脚本覆盖——**改 Lua 脚本无需重编译**，
-重启即生效；通过 WebUI 上传的适配器与在线编辑的源配置则即时生效。
-
-```lua
-return {
-  name = "mysrc",
-  version = "1.0.0",
-  endpoint = "/chat/completions",        -- 上游路径（可被 source.endpoint 覆盖）
-  headers = { ["X-Static"] = "v" },      -- 静态默认请求头（build_headers 缺省时使用）
-
-  -- 请求转换：把 OpenAI 格式 req 转成上游原生格式，返回字符串
-  transform_request = function(raw_json) ... end,
-
-  -- 响应转换：把上游原生响应转成统一格式字符串
-  --   { content, reasoning_content, finish_reason, token_usage{...}, tool_calls[{...}] }
-  transform_response = function(raw_json) ... end,
-
-  -- 流式分块转换：把上游 SSE data 转成 { content, done, ... }，返回 "" 则跳过
-  transform_stream_chunk = function(raw_chunk) ... end,
-
-  -- [可选] 动态请求头/签名钩子
-  -- meta = { url, method, body, api_key, timestamp, source={ name, meta={...} } }
-  build_headers = function(meta) return { ["X-App-Sign"] = sign } end,
-
-  -- [可选] 出向序列化（契约 v2）：上游不是 OpenAI 协议时接管写给客户端的字节。
-  -- 不声明则沿用内核的 OpenAI 兜底；声明即完全取代，内核不再混合字段。
-  serialize_response = function(result) return body_str end,
-  serialize_open_preamble = function(result) return bytes end,
-  serialize_chunk = function(delta) return bytes end,
-  serialize_close = function(result) return bytes end,
-}
-```
-
-内置信号辅助：`hmac_sha256_hex(key, data)`、`sha256_hex(data)`、`base64_encode(s)`、
-`tohex(s)`、`json.encode/decode`、`log(level, msg)`。
-
-### 内置适配器
-
-`openai` `deepseek` `anthropic` `gemini` `github` `groq` `mistral` `ollama` `kimicode`
-`qwen38` `sensenova` `trae`。
-
-`anthropic`/`gemini`/`ollama` 适配器内置多模态转换（`image_url` → 各自上游格式）；
-推理开关由中立的 `thinking` 字段表达，`deepseek` 适配器把它映射为
-`thinking.type = "disabled"`。
-
-**kimicode** 是展示 `build_headers` 的样例：云端校验调用方 app，需要按
-`meta.app_secret` 对时间戳+URL+请求体哈希做 HMAC 签名并附 `X-App-Sign` 等头。
-配好 `sources[].meta.{app_id, app_secret, app_agent}` 即可。
-
-## 桌面 GUI（Electron）
-
-可选独立产物，面向内网桌面端用户：**内嵌 ModelRouter 核心**（Clash Verge 形态），
-一键启停、系统托盘常驻、开机自启、静默启动，内容区一比一内嵌完整 WebUI
-（状态/对话/密钥/优先级/源/适配器 六个页面，免登录）。服务器用户继续使用纯 Go 二进制。
-
-### 两种安装包：Headless 与 Desktop
-
-发布到 Release 的安装包分为两类，面向不同用户：
-
-- **Headless（服务器版）**：纯核心二进制（无 Electron），配置驱动，适合服务器、
-  容器、systemd 等无人值守场景。发布包含 `deb` + `rpm`（含 systemd unit、内存调优
-  与示例配置）与 `tar.gz`（二进制 + `config.example.yaml` + `adapters/` + README），
-  Windows 为 `.zip`。
-- **Desktop（桌面版）**：Electron GUI 安装包，内嵌核心，适合个人桌面日常使用。
-
-### 选择 GUI 还是纯后端
-
-| 场景 | 推荐 | 理由 |
-| ------ | ------ | ------ |
-| 服务器 / 内网网关 / 无人值守常驻 | **Headless**（单二进制） | 极轻量（二进制 ~8MB；RSS 随源数量，单源 ~10MB、16 源 ~32–35MB，见[内存占用](#内存占用实测与调优)），零依赖单进程，直接跑在 systemd/任意容器里，远程管理 |
-| 个人桌面日常使用 / 多设备内网共享 | **Desktop**（GUI） | 免登录内嵌 WebUI、系统托盘一键启停、开机自启、静默后台，适合不懂命令行的使用者 |
-| Windows 桌面 | **Desktop** | 纯后端在 Windows 上需自行注册服务，GUI 提供原生托盘/自启体验 |
-| CI 一键出三平台安装包 | **Desktop 打包脚本** | `make gui-*` 系列出 deb/AppImage/NSIS，可进发行流水线 |
-
-两者完全同源：GUI 内嵌的就是纯后端的同一份 `llmsproxy` 核心（LuaJIT 版），
-配置/适配器格式完全一致，可随时互换。
-
-### 构建与运行
-
-```bash
-cd cmd/gui
-npm install
-make gui          # 或 npm run dev —— 开发运行（需先 make build 生成 bin/llmsproxy）
-make gui-deb      # 本机构建 deb（分享给其它 Linux 用户）
-make gui-dist     # 构建 deb + rpm + AppImage（linux，rpm 需系统 rpmbuild）
-make core-dist    # 构建核心 deb + rpm + tar.gz（服务器版，需 nfpm）
-make gui-win      # 构建 Windows nsis 安装包（本机 mingw + wine）
-make gui-win-docker  # 构建 Windows nsis 安装包（全 docker 自足，含 wine）
-make gui-dist-dir # 仅解包产物（调试用，不产安装包）
-```
-
-产物在 `cmd/build/gui-dist/`：`ModelRouter-<ver>.AppImage`、
-`modelrouter-gui_<ver>_amd64.deb`、`ModelRouter Setup <ver>.exe`（win）；
-核心包在 `cmd/build/dist/`：`llmsproxy_<ver>_amd64.deb`、`llmsproxy-<ver>.x86_64.rpm`。
-rpm 需系统 `rpmbuild`。每次打包后都会跑 `packaging/verify-dist.sh` 产物体检
-（大小下限门禁——1.3.0 曾因宿主 wine 损坏产出 264KB 的残缺 exe 却没有被拦住）。
-发布时会把产物重命名为 `ModelRouter-Desktop-*`（GUI）与 `ModelRouter-Headless-*`（纯后端）
-两类上传到 GitCode Release。
-
-#### Windows 打包（docker 固化方案，推荐）
-
-`make gui-win-docker` 一步完成：交叉编译核心 + NSIS 打包**全在 docker 内**，宿主机
-**无需 mingw、无需 wine、无需 node**。镜像内置 wine（含 i386 运行时），修复了
-此前宿主 wine 损坏（缺 syswow64 → `c0000135`）导致产出 264KB 残缺 exe 的问题。
-
-- 构建镜像：`cmd/gui/docker/win-builder/Dockerfile`（`golang:1.25` + mingw-w64 +
-  node + wine32/wine64 + 预编译 LuaJIT windows 版 `lua51.dll` 与 import lib）。
-  LuaJIT 源码取自 gitcode 镜像（国内可达），github 兜底；Go 依赖走 `https://goproxy.cn`。
-- 一键发布：`cmd/gui/scripts/dist-win-docker.sh` —— 核心编译 + electron-builder
-  NSIS 全部在容器内执行（`USE_SYSTEM_WINE=true` 走镜像内的 wine）；electron-builder
-  的 ~400MB 工具链缓存挂到 docker volume，二次构建增量复用。
-- 首次运行自动构建 `modelrouter/win-builder` 镜像（约 5–10 分钟）；已存在则直接复用。
-- 打包完成后自动跑 `packaging/verify-dist.sh` 门禁：exe 低于 5MB / deb·rpm·7z 低于
-  10MB 即失败——残缺安装包不可能再溜进 Release。
-
-```bash
-# 全 Windows 发布（核心重编 + NSIS）：
-make gui-win-docker
-```
-
-### 特性
-
-- **内嵌核心**：自动拉起捆绑的 `llmsproxy`（LuaJIT 版），配置/密钥/adapter 存于
-  用户数据目录 `<userData>/profile/`，首次运行自动生成随机 admin key 写入 `keys`
-  （非 seed）并自注入，WebUI 免登录、不会提示"更换初始密钥"。端口可在设置中更改（默认 8787）。
-- **系统托盘**：内核状态点、开机自启/静默启动开关、启停/重启内核、退出。
-- **静默启动**：`--silent` 参数或设置项，启动仅驻托盘不弹窗；首次运行始终显示窗口。
-- **开机自启**：Windows/macOS 用 `setLoginItemSettings`；Linux 写
-  `~/.config/autostart/modelrouter-gui.desktop`，静默开启时自动附加 `--silent`。

-A lightweight, unified OpenAI-compatible LLM gateway for internal networks —
-configure once, and let multiple services (agents, SDKs, bots) share many
-upstreams (DeepSeek, Qijiar, OpenAI, Anthropic, Gemini, Groq, Mistral, Ollama,
-KimiCode…) behind a single endpoint. Pick a specific model or use **AUTO** mode,
-which routes to the best healthy upstream by configured priority.
+An intranet gateway for people with several LLM subscriptions: configure once and
+let multiple services share the upstream capacity. Pick a model explicitly, or let
+`AUTO` choose by priority among the sources that are currently healthy.
 
-> **Lightweight, no recompile to add sources**: the gateway is a single Go
-> binary (8-12 MB, ~8 MB stripped; zero runtime dependencies). Adding or switching an upstream is
-> just a `sources` entry in `config.yaml` (or via the WebUI) or a `.lua`
-> adapter — **no Go changes, no recompile**. Changes submitted through the
-> WebUI take effect immediately (hot reload); editing `config.yaml` or a `.lua`
-> file under `adapter_dir` by hand requires a process restart.
+The gateway itself is a single Go binary (~10 MB, no runtime dependencies). Adding
+or switching an upstream is a `sources` entry in `config.yaml` (or the WebUI), or a
+dropped-in `.lua` adapter — **no Go changes, no rebuild**. Changes submitted through
+the WebUI take effect immediately; editing `config.yaml` or a `.lua` adapter file
+directly requires a restart.
 
-## Overview
+## What it does
 
-Exposes a standard `OpenAI Chat Completions` API (`/v1/chat/completions` +
-`/v1/models`) to your internal network, translating between multiple upstream
-protocols via **Lua adapters**. Supports one-shot calls, SSE streaming,
-**AUTO model routing**, multimodal passthrough, and tool calls.
-
-Extracted and independently evolved from the multi-source LLM adapter layer of
-[HomeAgent](https://gitcode.com/JianFeeeee/HomeAgent)
-(`internal/agent/api/provider.go` + `internal/lua/adapters/*`).
-
-## Features
-
-- **Multi-source**: any number of upstream sources in one process, routed by the
-  request's `model`.
-- **AUTO mode**: with `default_model: AUTO`, scheduling follows the tiered AUTO
-  chain saved on the Priority page (see below).
-- **Unified output**: every source speaks OpenAI format (incl.
-  `reasoning_content`, `tool_calls`, `usage`).
-- **Image generation**: `POST /v1/images/generations`, routed to models with
-  `kind: image`.
-- **Per-model quota**: each key gives every model its own token and request caps
-  plus a reset period (hour/week/month/custom N hours). One model running out
-  affects only that model — the key's other models keep working. Exhaustion
-  answers 429 + `Retry-After` naming the model, so a client resumes when the
-  window rolls over; admin keys are never capped.
-- **Multimodal**: `content` arrays (`image_url` etc.) pass through losslessly;
-  Anthropic/Gemini/Ollama are translated automatically.
-- **LuaJIT VM**: golua-binding LuaJIT; each adapter has its own VM + worker
-  pool for safe concurrency. Pools are **elastic**: the sum of `max_concurrent`
-  over an adapter's sources is a ceiling, not a preallocation — states are booted
-  on demand and reclaimed when demand drops, so an idle gateway holds close to
-  zero Lua states. The grow step follows the adapter's max concurrency
-  (`clamp(ceil(max/8), 1, 8)`, and never exceeds the number of queued callers);
-  the shrink step follows the live connection count
-  (`clamp(ceil(slack/(1+in_use)), 1, slack)`), so an idle pool collapses in one
-  round while a busy one gives up a single state at a time.
-- **On-demand request logs**: dashboard totals are computed from the **full**
-  audit history (streamed once at startup and released — 29 MB / 221k lines in
-  ~260 ms), while the raw records are never held in memory: the dashboard loads
-  one screen, scrolling pages the rest straight off disk, CSV export streams in
-  O(1) memory, and leaving the page releases everything.
-- **Self-healing cooldown**: cooldown is capped at 5 minutes and, past the
-  window's midpoint, exactly one probe request is allowed through; a recovered
-  upstream (or a reset quota) returns to full rotation on that probe instead of
-  waiting out the window.
-- **disable_thinking**: `disable_thinking: true` toggles reasoning per-request.
-- **Lua adapter protocol**: each source mounts a `.lua` adapter with
-  `transform_request` / `transform_response` / `transform_stream_chunk` — all
-  protocol differences live in Lua, Go only schedules and proxies.
-- **Signature / header hooks**: adapters may define `build_headers(meta)` to
-  inject/sign request headers before the HTTP call (e.g. KimiCode style
-  app-validation), with helpers like `hmac_sha256_hex`, `sha256_hex`,
-  `base64_encode`.
-- **WebUI**: built-in management page to view/add/edit sources & models, edit
-  the AUTO chain, and manage per-key model scopes, persisted to a runtime file.
-- **Encrypted secrets at rest**: upstream `api_key`, custom header values and
-  gateway keys are stored AES-256-GCM encrypted (`master.key` 0600 next to the
-  runtime file, or `LLMS_PROXY_MASTER_KEY`).
-- **Live source probing**: the status page probes each source
-  (`GET {base}/models`, falling back to a minimal chat call) without touching
-  the scheduler's backoff state; errors are shown on hover.
-- **Auth**: the gateway validates client keys via `gateway_keys`; independent
-  from each upstream's own key.
-- **Streaming**: SSE `chat.completion.chunk` with a role-first chunk and
-  `[DONE]` terminator.
+- **One OpenAI-compatible API**: `/v1/chat/completions`, `/v1/models`,
+  `/v1/images/generations`. Every source speaks the same shape outwards, including
+  `reasoning_content`, `tool_calls` and `usage`.
+- **Many sources, one AUTO chain**: configure any number of upstreams; `AUTO`
+  follows the priority tiers saved in the WebUI, fails over between them, cools
+  down broken sources and probes them back to health at half-cool.
+- **Protocol differences live in Lua**: each source binds a `.lua` adapter that
+  transforms requests, responses and stream chunks both ways, and can sign headers
+  via `build_headers(meta)`. Vendor knowledge stays out of the Go kernel.
+- **Plugins are independent**: business extensions (channel login, billing, quota
+  probing) are external Lua plugins loaded from `plugin_dir`. They are not compiled
+  into the binary and not shipped in release archives, and they talk to the kernel
+  only through the `modelrouter` SDK.
+- **Multi-tenant keys**: gateway keys are separate from upstream keys, and can be
+  scoped to a model set, an AUTO chain and a quota.
+- **Encrypted at rest**: upstream keys, custom header values and gateway keys are
+  sealed with AES-256-GCM; `master.key` is 0600, or injected via
+  `MODELROUTER_MASTER_KEY`.
+- **Observability**: live source probing, HTTP access log, config-change audit,
+  request and usage CSV export. Writes are kept off the request hot path.
 
 ## Quick start
 
 ```bash
-GOMODCACHE=... GOPROXY=off go build -tags luajit -o llmsproxy ./cmd/llmsproxy
-./llmsproxy -config config.yaml    # first run generates a default config and prints a random admin key
+# LuaJIT development libraries are required; -tags luajit is mandatory
+GOMODCACHE=... GOPROXY=off go build -tags luajit -o modelrouter ./cmd/modelrouter
+
+# First run generates a default config and prints a random admin key
+./modelrouter -config config.yaml
 ```
 
-> Depends on [golua](https://github.com/aarzilli/golua) (LuaJIT bindings).
-> You **must** build with `-tags luajit`; otherwise the built-in superset
-> gopher-lua path is used (behavior differs slightly).

-> **No config is shipped in the repo** (config files carry real keys). On
-> first run the binary generates a default config at the `-config` path: a
-> random admin key (printed to the startup log), loopback-only `127.0.0.1:8080`,

 ```bash
-# no key -> 401
+# No key -> 401
 curl http://127.0.0.1:8080/v1/models
 
-# one-shot ($KEY = the admin key printed at first startup)

 curl -H "Authorization: Bearer $KEY" \
      -d '{"model":"AUTO","messages":[{"role":"user","content":"hi"}]}' \
      http://127.0.0.1:8080/v1/chat/completions
 
-# streaming
+# Streaming
 curl -N -H "Authorization: Bearer $KEY" \
      -d '{"model":"AUTO","stream":true,"messages":[{"role":"user","content":"hi"}]}' \
      http://127.0.0.1:8080/v1/chat/completions
 ```
 
-Any OpenAI SDK works: point `base_url` at the gateway, use any authorized
-gateway key as the API key.
-
-## Configuration
-
-Generated on first run at the `-config` path (default `./config.yaml`). Core fields:
-
-```yaml
-listen: 127.0.0.1:8080        # bind address (keep internal/loopback)
-gateway_keys: [sk-gw-<random>] # initial admin key seed (random per install), migrated to the store on first start
-default_model: AUTO           # when model is unroutable, follow the AUTO chain
-adapter_dir: adapters         # Lua adapter dir; created+seeded if missing, read-only otherwise
-runtime_file: runtime.json    # WebUI-edited sources/keys/AUTO chain persist here
-
-sources:
-  - name: deepseek
-    base_url: https://api.deepseek.com
-    api_key: sk-...            # or api_key_env: SOME_ENV to read from an env var
-    adapter: deepseek
-    max_concurrent: 8
-    models:
-      - id: deepseek-v4-flash

-```
-
-Sensitive fields in the runtime file (`runtime_file`) are encrypted at rest:
-
-- AES-256-GCM, stored as `enc:v1:<base64>`.
-- Master key source: env var `LLMS_PROXY_MASTER_KEY` (64 hex chars), else a
-  `master.key` file next to the runtime file; if neither exists it is generated
-  on first start (mode 0600).
-- Old plaintext files still load; the first UI save migrates the whole file to
-  ciphertext.
-- Back up `master.key` with your config — losing it makes the secrets
-  undecryptable. Do not commit it.
-
-### Gateway keys (multi-key)
-
-Gateway auth uses a "multi-key + role + model scope" model. Keys are persisted
-under the `keys` field of the runtime file (encrypted at rest):
-
-- The `gateway_keys` config is only an **initial admin key seed** — it is
-  migrated into the runtime store on first start and no longer drives auth.
-- **Important: after first start, replace the admin key via the WebUI Keys
-  page.** The seed key is written in plaintext in `config.yaml`, so keeping it
-  active is a security risk; create a new admin key, log in with it, then
-  delete the seed key.
-- The WebUI **Keys page** creates/deletes keys. Each key has a role (`admin`
-  manages everything, `user` sees only its own key) and an optional **model
-  scope** (model + source + token quota + reset period). Each model brick shows
-  its own budget badge (e.g. `1.0K 77×·1h`, `∞` when uncapped); clicking it
-  edits that model's token quota, request quota and reset period. Quotas apply
-  per model, so one model running out never blocks the key's others. The
-  "My key" view shows a user its model scopes and their budgets.
-- Clients authenticate with any authorized key's plaintext as
-  `Authorization: Bearer <key>`.
-- Deleting a key removes it from the store immediately.
-
-#### Per-key usage quota
-
-**Quotas are per model.** Each key's `models[]` list gives every model its own
-token budget and request budget. One model running out affects only that model
-— the key's other models keep working.
-
-```yaml
-keys:
-  - key: sk-gw-<hex>
-    role: user
-    name: agent-alice
-    models:
-      - model: deepseek-v4-flash
-        token_quota: 1000000   # this key's token budget for this model
-        req_quota: 20000       # requests within the window
-        period: nhour          # "" | hour | week | month | nhour
-        hours: 6               # n-hour only
-      - model: AUTO
-        token_quota: 5000000   # AUTO is a quota entry like any other
-        period: hour
-      - model: kimi-k3        # no quota listed = unlimited
-```
-
-- **There is deliberately no key-wide total.** A key-wide cap would make
-  "move A's budget to B" a global reallocation; per-model budgets keep each
-  model independently controllable, so it stays visible which model is
-  actually consuming the spend.
-- `period`: empty = never resets (lifetime total); `hour` / `week` / `month` =
-  fixed windows; `nhour` + `hours` = a custom hour count. **A misspelled
-  period is rejected at write time** rather than silently becoming a
-  never-resetting quota.
-- Quotas are isolated per key *and* per model within a key: one key exhausting
-  `m1` never draws on another key's budget, and never blocks the same key's
-  `m2`.
-- Usage counts chat, streaming and image requests, and survives a restart by
-  replaying the audit log (40 days retained, covering the longest `month`
-  window).
-- An exhausted quota returns **429 + `Retry-After`**
-  (`rate_limit_exceeded`) and the message names the model that ran out, so a
-  client resumes when the window rolls over; a model the key may not use stays
-  403. **Admin keys are never capped** (quotas on their scopes are not
-  enforced either), so a cap can never lock the operator out.
-- Buckets are whole unix hours, so a window frees up at most an hour late
-  (deliberately freeing late rather than overspending).
-- `PUT /api/keys/{key}` submits quotas by submitting `models` — the caps are
-  part of the scope, so there is no second budget that can drift out of sync
-  with the model list. An explicit `0` lifts that model's cap.
-
-##### Quota rejection vs capacity rejection
-
-A quota is checked at the entry point and occupies no upstream slot, so it is a
-cheap rejection. Running out of capacity instead waits out the bounded
-`busyWait` before answering 503. Measured (capacity 8, 0.6 s/request, 100
-concurrent clients):
-
-| Case | Status | Latency | Reaches upstream |
-|---|---|---|---|
-| Quota spent (`req_quota` 50, 100 concurrent) | `429 rate_limit_exceeded` + `Retry-After` | **19–21 ms** | no |
-| Capacity exhausted (same topology, no quota) | `503 upstream_error` | ~2.6 s (`busyWait`) | overflow: no |
-
-So a client can tell "wait for the window to roll over" apart from "wait for
-upstream capacity" — the first only needs patience, the second usually means
-back off concurrency or switch sources.
-
-##### What the quota costs
-
-Buckets are kept per (key, model, whole unix hour) for 40 days. Measured on an
-AMD 7840HS:
-
-- A window query scans the window, not the whole retention: 49 ns for 1 h,
-  55 ns for 24 h, 3.9 µs for 30 d.
-- Recording one request: 283 ns, 3 allocations (unchanged from before this
-  feature; the allocations come from the record ring buffer).
-- Memory: the production shape (7 keys x 8 models x 2 sources at full 40-day
-  retention) costs about **3.7 MB**. The `source::model` bucket used by a
-  source-pinned quota is created **lazily** — it is maintained only once some
-  quota actually pins that source, because writing it on every record would
-  cost an extra 18 MB at 20 keys x 8 models x 3 sources.
-  The trade-off: usage recorded before a pinned quota was configured cannot be
-  split by source afterwards, so **a pinned quota may under-count its first
-  window**.
-
-```
-HTTP/1.1 429 Too Many Requests
-Retry-After: 2100
-{"error":{"type":"rate_limit_exceeded","message":"token quota exceeded for \"deepseek-v4-flash\" (5000000/5000000)"}}
-```
-
-### Model routing
-
-`/v1/chat/completions` `model` resolution order:
-
-1. `source/model` or `source:model` prefix → pinned source;
-2. exact match of a source's `model`;
-3. with `default_model: AUTO` → follow the AUTO chain from the Priority page
-   (see below);
-4. otherwise the request errors.
-
-Any OpenAI client can pin to a source by setting `model` to its
-`name/anything`; `AUTO` (or the gateway's `default_model: AUTO`) follows the
-tiered AUTO chain.
-
-### AUTO chain (Priority page)
-
-AUTO scheduling is driven **only** by the rules saved on the Priority page. The
-numeric `models[].priority` in source configs no longer participates in
-scheduling and is no longer shown. **Chat and image generation are two
-independent chains**, switched in the Priority page via the `Chat / Image` toggle:
-
-- **Chat chain** (`auto` field): serves `POST /v1/chat/completions` with
-  `model: AUTO`; only `kind: chat` models are honored (image slots are skipped).
-- **Image chain** (`auto_image` field): serves `POST /v1/images/generations` with
-  `model: AUTO`; only `kind: image` models are honored. With no image chain
-  configured, AUTO image generation falls back to legacy discovery (all sources
-  exposing an image model, in registry order) for backward compatibility.
-
-Each rule is one "slot": `{ model, source, tier, token_quota, period, hours }`.
-
-- `tier` is the priority tier: models in the same tier sit side by side and
-  share it; tiers run high → low.
-- The same model may appear in several slots (e.g. A low → B low → A high →
-  B high) and is tried in tier order.
-- `token_quota` > 0 means the slot is skipped once its tokens within the reset
-  window are exhausted; `period` supports `hour` / `week` / `month` / `nhour`
-  (with `hours`); empty = unlimited.
-- Within a tier, slots run by preference score; cooling / quota-exhausted /
-  hard-failed slots fall through to the next tier, and total failure returns
-  503 with a per-tier summary.
-
-### Sources vs. adapters
-
-- A **source** describes a connection to an upstream: `name`, `base_url`,
-  `api_key`, model list and priorities.
-- An **adapter** is the protocol translation logic (Lua script): converts the
-  unified OpenAI request to the upstream's native format and back.
-- One adapter serves many sources (e.g. `openai.lua` for any OpenAI-compatible
-  site); one source can switch adapters via its `adapter` field.
-- Sources decide *whom to talk to and which models to expose*; adapters decide
-  *how to talk*. They are linked by the `adapter` field inside each `sources[]`
-  entry.
-
-Loading flow (assembled by `Core` in `internal/core`):
-
-1. On startup `lua.NewVM(adapter_dir)` loads all adapters: built-in ones
-   (embedded at compile time) + same-name override files under `adapter_dir`.
-2. `config.Load` reads `config.yaml`; `config.NewStore(runtime_file)` reads
-   WebUI-edited runtime sources; both are merged by name.
-3. `rebuildRegistry` creates a `provider.Provider` per source (holding its
-   adapter), sizing the adapter's worker pool from the source's concurrency
-   limit.
-4. Incoming requests are routed by `Registry` to a provider, which calls the
-   adapter's `transform_request` → HTTP call → `transform_response` /
-   `transform_stream_chunk`.
-
-"Add/Edit source", "Upload adapter", "AUTO chain edits" and "per-key model
-scopes" in the WebUI take effect immediately (written to the runtime file /
-`adapter_dir`, then reassembled — no restart). Directly editing `config.yaml`
-or files under `adapter_dir` requires a process restart.
-
-Deleting a source/adapter in the WebUI truly removes runtime (UI-created)
-sources and `.lua` files; base sources defined in `config.yaml` cannot rewrite
-that file, so they are hidden via a deletion tombstone (still hidden after
-restart) and can be restored by re-adding the same name in the UI.
-
-### Source templates (multi-key balancing)
-
-When several upstream keys share one config (URL / adapter / model list /
-concurrency / rpm), copying the whole source block N times is wasteful. A
-**source template** stores every source field except `name` and `api_key`, so you
-create N key-only-different sources from one shared skeleton — natural multi-key
-load balancing (each expanded source schedules, cools down, and reports health
-independently).
-
-- WebUI Sources page, top-right **Templates** button: list all templates with
-  edit / delete / create.
-- Add-source dialog has two header buttons:
-  - **From template** → pick a template → form auto-fills (name + key still
-    yours to enter);
-  - **As template** → save the current form's non-key/name fields as a template.
-- Templates persist in the runtime file's `source_templates` field alongside
-  runtime sources (hot-managed, apply immediately). Templates hold no secret
-  keys, so they're safe to share / version-control.
-
-A template is just a recipe — it doesn't become a source by itself. Only the
-key-bearing sources created from it carry real traffic.
-
-### Memory footprint (measured and tuned)
-
-Memory is not a constant: it scales with the **number of configured sources**
-(each source owns an `http.Transport` with its connection pool plus per-model
-health state), not with uptime. Measured on this machine (Linux x86_64, 12 cores):
-
-| Deployment shape | Startup RSS | Settled RSS |
-|---|---|---|
-| 1 source / 1 adapter (minimal) | ~4 MB | ~10 MB |
-| 1 source + a 29 MB audit history | ~19 MB | ~20 MB |
-| **16 sources / 13 adapters / 59 models (this host)** | ~28 MB | **~32-35 MB** |
-
-> For reference, the same production config used **~105 MB** before this round of
-> work. The reduction comes from three places: raw audit records are no longer kept
-> resident (~25 MB — the aggregates still scan the full history, but the scan
-> releases as it goes), Lua state pools no longer grow monotonically, and the two
-> runtime knobs below.
-
-Breakdown of the production instance (per-region, from `/proc/<pid>/smaps`):
-
-| Region | RSS | Notes |
-|---|---|---|
-| Go heap | ~14 MB | provider/registry/scheduler state + connection-pool buffers |
-| Other anonymous (thread stacks / LuaJIT chunks / runtime) | ~12 MB | scales with thread count and loaded adapters |
-| Binary text+rodata | ~8 MB | mapped executable pages (read-only, reclaimable by the kernel) |
-| Go runtime reservations | ~4 MB | the 2 GB+ you see in VSZ is address space, not physical memory |
-| Shared libraries | ~3 MB | libc / libluajit / libm |
-
-**Two recommended deployment knobs** (environment only, no code change):
-
-```ini
-# /etc/systemd/system/llmsproxy.service
-Environment=GOGC=50
-Environment=MALLOC_ARENA_MAX=2
-```
-
-- `MALLOC_ARENA_MAX=2`: LuaJIT allocates through cgo into glibc malloc, and glibc
-  allows up to `8 x nproc` per-thread arenas. Every OS thread that touches malloc
-  claims one (~1 MB each) and **never returns it to the OS**. Measured: 8-15
-  arenas (7-12 MB) down to **0**.
-- `GOGC=50`: halves the Go heap growth target. **It does nothing on its own** —
-  the heap it saves is immediately consumed by additional glibc arenas (measured
-  20.3 -> 21.5 MB, i.e. slightly worse) — so it must be paired with
-  `MALLOC_ARENA_MAX`. Together they cut settled RSS by **~19%**. The gateway is
-  I/O bound (1min10s of CPU per 9 hours here), so the extra GC cycles are free.
-
-> The desktop build (Electron) already injects both when spawning the embedded
-> core (`cmd/gui/main.js`); exporting either variable yourself overrides it. If you
-> write your own systemd unit or container spec, add them there.
-
-Optional: `GOMEMLIMIT=48MiB` as a soft ceiling saves roughly 1 MB more, at the
-cost of GC turning aggressive as the limit approaches. Not worth it for a relaxed
-deployment.
-
-### disable_thinking
-
-With `"disable_thinking": true` in the request body, the gateway passes it to
-each adapter; the DeepSeek adapter maps it to `extra_body.thinking.type =
-"disabled"`, other sources follow their own protocol.
-
-### WebUI
-
-Built-in admin page at `GET /`; after login you can:
-
-- **Status**: source online state (live probe, error on hover), per
-  model/source/key usage stats, request records filtered by key, and CSV export
-  over a time range; click a model to pin the connection snippet to it.
-- **Chat**: streaming / non-streaming debug.
-- **Keys**: create/edit gateway keys, set per-key model scopes (model + source +
-  token quota + reset period); admins manage all keys, users see only their own.
-- **Priority**: drag blocks to build the tiered AUTO chain.
-- **Sources**: add/edit/delete upstream sources online (secrets stored
-  encrypted).
-- **Adapters**: upload / delete Lua adapter scripts.
-
-Changes persist to `runtime_file` (survive restarts).
-
-## Lua adapter protocol
-
-Full API: **[Lua adapter docs](docs/lua-adapters.md)**
-([中文](docs/lua-adapters-en.md)).
-
-Each adapter is a Lua script returning a table
-(`internal/lua/adapters/<name>.lua`), overridable by a same-name file under
-`adapter_dir` — **no recompile needed**, restart to take effect; uploads via
-the WebUI take effect immediately.
-
-```lua
-return {
-  name = "mysrc",
-  version = "1.0.0",
-  endpoint = "/chat/completions",        -- upstream path (source.endpoint overrides)
-  headers = { ["X-Static"] = "v" },      -- static default headers (fallback)
-
-  -- request: convert unified OpenAI req -> upstream native format, return string
-  transform_request = function(raw_json) ... end,
-
-  -- response: convert upstream response to unified format string
-  --   { content, reasoning_content, finish_reason, token_usage{...}, tool_calls[{...}] }
-  transform_response = function(raw_json) ... end,
-
-  -- streaming chunk: convert upstream SSE data to { content, done, ... }; "" skips
-  transform_stream_chunk = function(raw_chunk) ... end,
-
-  -- [optional] dynamic headers / signature hook
-  -- meta = { url, method, body, api_key, timestamp, source={ name, meta={...} } }
-  build_headers = function(meta) return { ["X-App-Sign"] = sign } end,
-}
-```
-
-Shared helpers: `hmac_sha256_hex(key, data)`, `sha256_hex(data)`,
-`base64_encode(s)`, `tohex(s)`, `json.encode/decode`, `log(level, msg)`.
-
-### Built-in adapters
-
-`openai` `deepseek` `anthropic` `gemini` `github` `groq` `mistral` `ollama`
-`kimicode` `qwen38` `sensenova` `trae`.
-
-`anthropic`/`gemini`/`ollama` include multimodal conversion
-(`image_url` → their native format); with `disable_thinking` the `deepseek`
-adapter sets `extra_body.thinking.type` to `disabled`.
-
-**kimicode** demonstrates `build_headers`: the cloud validates the calling
-app, so you HMAC-sign timestamp+URL+body with `meta.app_secret` and add
-`X-App-Sign`-style headers. Configure `sources[].meta.{app_id, app_secret,
-app_agent}`.
-
-## Desktop GUI (Electron)
-
-Optional standalone product for desktop users on your internal network: an
-**embedded ModelRouter core** (Clash Verge-style): one-click start/stop, system
-tray, autostart, silent launch, and a pixel-for-pixel embedded full WebUI
-(Status/Chat/Keys/Priority/Sources/Adapters — no login needed). Server users
-keep using the plain Go binary.
-
-### Two installer kinds: Headless and Desktop
-
-Release installers ship in two flavors for different audiences:
-
-- **Headless (server)**: the plain core binary (no Electron), config-driven,
-  for servers / containers / systemd / unattended runs. Ships as `deb` + `rpm`
-  (systemd unit with memory tuning + example config) and `tar.gz` (binary +
-  `config.example.yaml` + `adapters/` + README), Windows as `.zip`.
-- **Desktop (desktop app)**: the Electron GUI installer with an embedded core,
-  for personal daily desktop use.
-
-### GUI vs. plain backend
-
-| Scenario | Pick | Why |
-| ---- | ---- | ---- |
-| Server / intranet gateway / unattended long-running | **Headless** (single binary) | ~8 MB binary; RSS scales with the number of sources (~10 MB for one, ~32-35 MB for 16 — see [Memory footprint](#memory-footprint-measured-and-tuned)), zero-dep single process — drop it into systemd or any container, remote admin |
-| Personal desktop daily use / multi-device intranet sharing | **Desktop** (GUI) | no-login embedded WebUI, tray one-click, autostart, silent background — for non-CLI users |
-| Windows desktop | **Desktop** | plain backend needs manual service registration; GUI ships native tray/autostart |
-| CI one-shot 3-platform installers | **Desktop packaging scripts** | `make gui-*` emits deb / AppImage / NSIS, drops straight into a release pipeline |
-
-Both share the exact same `llmsproxy` core (LuaJIT build) — configs and
-adapters are fully compatible, freely interchangeable.
-
-### Build & run
+Any OpenAI SDK works: point `base_url` at the gateway and use an authorized gateway
+key as `api_key`.

+
+## Renamed from llmsproxy
+
+The product name has been ModelRouter for a while; the binary, config directory,
+service name and environment variables are now `modelrouter` as well:
+
+| Before | After |
+|---|---|
+| `llmsproxy` (binary) | `modelrouter` |
+| `/etc/llmsproxy/` | `/etc/modelrouter/` |
+| `llmsproxy.service` | `modelrouter.service` |
+| `LLMSPROXY_*` | `MODELROUTER_*` |
+
+Existing installs migrate with a dry-run-by-default script (copies, never moves,
+and can roll back):
 
 ```bash
-cd cmd/gui
-npm install
-make gui            # or npm run dev — dev run (needs make build first for bin/llmsproxy)
-make gui-deb        # local deb (share with other Linux users)
-make gui-dist       # deb + rpm + AppImage (linux; rpm needs system rpmbuild)
-make core-dist      # core deb + rpm + tar.gz (server edition; needs nfpm)
-make gui-win        # Windows NSIS (host mingw + wine)
-make gui-win-docker # Windows NSIS, fully dockerized (wine in image; no host mingw/node/wine)
+sudo ./packaging/migrate-to-modelrouter.sh              # preview
+sudo ./packaging/migrate-to-modelrouter.sh --apply      # apply
+sudo ./packaging/migrate-to-modelrouter.sh --rollback --apply
 ```
 
-Artifacts land in `cmd/build/gui-dist/`: `ModelRouter-<ver>.AppImage`,
-`modelrouter-gui_<ver>_amd64.deb`, `ModelRouter Setup <ver>.exe` (win); core
-packages land in `cmd/build/dist/`: `llmsproxy_<ver>_amd64.deb`,
-`llmsproxy-<ver>.x86_64.rpm`. Both target families run
-`packaging/verify-dist.sh` afterwards — a size floor that rejects degenerate
-installers (1.3.0 shipped a 264 KB NSIS stub because the host wine was broken
-and nothing caught it). At release time artifacts are renamed into the
-`ModelRouter-Desktop-*` (GUI) and `ModelRouter-Headless-*` (plain backend)
-families before upload to GitCode Releases.
+Old paths and old environment variable names are still accepted on the read side,
+so an upgrade cannot fail merely because of ordering. `deploy.sh` refuses to run
+when it finds the old `/etc/llmsproxy` without a new config, because that would
+deploy a gateway with no key and no sources.
 
-#### Windows packaging (dockerized, recommended)
-
-`make gui-win-docker` does cross-compile + NSIS **entirely in docker**; the host
-needs **no mingw, no wine, no node**. Wine (with the i386 runtime) lives inside
- the image, fixing the broken-host-wine failure that produced the 264 KB stub
-installer.
-
-- Image: `cmd/gui/docker/win-builder/Dockerfile` (`golang:1.25` + mingw-w64 +
-  node + wine32/wine64 + prebuilt LuaJIT for Windows: `lua51.dll` + import lib).
-  LuaJIT source comes from the gitcode mirror (reachable in CN) with github
-  fallback; Go modules go through `https://goproxy.cn`.
-- One-shot release: `cmd/gui/scripts/dist-win-docker.sh` — core build + NSIS
-  packaging run inside the container (`USE_SYSTEM_WINE=true` uses the image's
-  wine); electron-builder's ~400 MB toolchain cache lives in a docker volume so
-  later builds reuse it.
-- The `modelrouter/win-builder` image is auto-built on first run (~5-10 min)
-  and reused afterwards.
-- After packaging, `packaging/verify-dist.sh` runs as a gate: an exe under
-  5 MB (or a deb/rpm/7z under 10 MB) fails the build — a broken installer can
-  never reach a Release again.
-
-```bash
-# Full Windows release (rebuild core + NSIS):
-make gui-win-docker
-```
-
-### Features
-
-- **Embedded core**: auto-spawns the bundled `llmsproxy` (LuaJIT build);
-  config/keys/adapters live in `<userData>/profile/`. First run generates a
-  random admin key written into `keys` (not seed) and self-injects it — WebUI
-  needs no login and never nags about changing the initial key. Port changeable
-  in settings (default 8787).
-- **System tray**: core status dot, autostart/silent toggles, start/stop/restart
-  core, quit.
-- **Silent launch**: `--silent` flag or setting — starts to the tray only;
-  first run always shows the window.
-- **Autostart**: `setLoginItemSettings` on Windows/macOS; writes
-  `~/.config/autostart/modelrouter-gui.desktop` on Linux, appending `--silent`
-  when silent mode is on.
+The plugin SDK follows the same naming: the only public entry point is
+`modelrouter` (`llmsproxy` remains a compatibility alias). See
+[docs/plugins.md](docs/plugins.md).

-## Development & collaboration
-
-- **Git branching workflow**: main / feature / release-branch conventions in
-  **[docs/git-workflow-en.md](docs/git-workflow-en.md)**
-  ([中文](docs/git-workflow.md)). The line: `main` is always deployable →
-  features merge into `main` → cut `release/vX.Y.Z` and tag → release → hotfixes
-  land on the release branch and are cherry-picked back into `main`.
-- **Lua adapter protocol**: see
-  **[docs/lua-adapters-en.md](docs/lua-adapters-en.md)**
-  ([中文](docs/lua-adapters.md)).
-
-## Tests
+## Development and tests
 
 ```bash
-go test -tags luajit ./...
+go test -tags luajit ./...           # everything
+go test -tags luajit ./internal/lua  # one package (required for LuaJIT changes)
 ```
 
-Covers: config validation, adapter load/transform, signature hooks, gateway
-auth, SDK round trip, SSE streaming, model routing, multimodal passthrough and
-disable_thinking.
+- Branch and release discipline: [docs/git-workflow-en.md](docs/git-workflow-en.md).
+- Plugins live in `plugin_dir`. The gateway never creates, overwrites or deletes
+  plugin files, and a desktop upgrade never touches them either.

+
+> 本文档由 README 拆分而来：Lua 适配器协议与内置适配器清单。
+> 编写适配器的完整参考见 [lua-adapters.md](lua-adapters.md)。
+> 返回 [README](../README.md)。
+
+## Lua 适配器协议
+
+完整 API 见 **[Lua 适配器 API 文档](docs/lua-adapters.md)**（[English](docs/lua-adapters-en.md)）。
+
+每个适配器是一个返回 table 的 Lua 脚本（`internal/lua/adapters/<name>.lua`），
+加载时可被 `adapter_dir` 下的同名脚本覆盖——**改 Lua 脚本无需重编译**，
+重启即生效；通过 WebUI 上传的适配器与在线编辑的源配置则即时生效。
+
+```lua
+return {
+  name = "mysrc",
+  version = "1.0.0",
+  endpoint = "/chat/completions",        -- 上游路径（可被 source.endpoint 覆盖）
+  headers = { ["X-Static"] = "v" },      -- 静态默认请求头（build_headers 缺省时使用）
+
+  -- 请求转换：把 OpenAI 格式 req 转成上游原生格式，返回字符串
+  transform_request = function(raw_json) ... end,
+
+  -- 响应转换：把上游原生响应转成统一格式字符串
+  --   { content, reasoning_content, finish_reason, token_usage{...}, tool_calls[{...}] }
+  transform_response = function(raw_json) ... end,
+
+  -- 流式分块转换：把上游 SSE data 转成 { content, done, ... }，返回 "" 则跳过
+  transform_stream_chunk = function(raw_chunk) ... end,
+
+  -- [可选] 动态请求头/签名钩子
+  -- meta = { url, method, body, api_key, timestamp, source={ name, meta={...} } }
+  build_headers = function(meta) return { ["X-App-Sign"] = sign } end,
+
+  -- [可选] 出向序列化（契约 v2）：上游不是 OpenAI 协议时接管写给客户端的字节。
+  -- 不声明则沿用内核的 OpenAI 兜底；声明即完全取代，内核不再混合字段。
+  serialize_response = function(result) return body_str end,
+  serialize_open_preamble = function(result) return bytes end,
+  serialize_chunk = function(delta) return bytes end,
+  serialize_close = function(result) return bytes end,
+}
+```
+
+内置信号辅助：`hmac_sha256_hex(key, data)`、`sha256_hex(data)`、`base64_encode(s)`、
+`tohex(s)`、`json.encode/decode`、`log(level, msg)`。
+
+### 内置适配器
+
+`openai` `deepseek` `anthropic` `gemini` `github` `groq` `mistral` `ollama` `qwen38` `sensenova`
+`qwen38` `sensenova` `trae`。
+
+`anthropic`/`gemini`/`ollama` 适配器内置多模态转换（`image_url` → 各自上游格式）；
+推理开关由中立的 `thinking` 字段表达，`deepseek` 适配器把它映射为
+`thinking.type = "disabled"`。
+
+适配器可用 `build_headers(meta)` 注入签名头。示例见 `adapters/` 下任一脚本的
+`build_headers` 实现；云端校验调用方 app 时需要按
+`meta.app_secret` 对时间戳+URL+请求体哈希做 HMAC 签名并附 `X-App-Sign` 等头。
+配好 `sources[].meta.{app_id, app_secret, app_agent}` 即可。

+> 返回 [README](../README.md)。
+
+## 配置文件
+
+首次运行在 `-config` 路径自动生成默认配置（默认 `./config.yaml`），核心字段：
+
+```yaml
+listen: 127.0.0.1:8080        # 网关监听地址（建议绑内网/回环）
+gateway_keys: [sk-gw-<随机>]  # 初始 admin 密钥（每次安装随机生成，仅首启写入运行时存储用）
+default_model: AUTO           # model 无法路由时自动按优先级链选源
+adapter_dir: adapters         # Lua 适配目录；目录不存在时首启创建并 seed 内置，存在则只读
+runtime_file: runtime.json    # WebUI 编辑的源/密钥/AUTO 链持久化到此文件
+

+    base_url: https://api.deepseek.com
+    api_key: sk-...            # 也可用 api_key_env: SOME_ENV 引用环境变量（不落盘明文）
+    adapter: deepseek
+    max_concurrent: 8
+    models:
+      - id: deepseek-v4-flash
+        priority: 100          # YAML 源首次启动会 seed 进 AUTO 链的初值
+        kind: chat
+      - id: deepseek-v4-pro
+        priority: 60
+        kind: chat
+    # 静态请求头（比适配器默认优先）
+    headers: { X-Tenant: prod }
+    # 传给 Lua build_headers 的透传元数据
+    meta: { app_id: x, app_secret: y }
+    temperature: 0.7
+    max_tokens: 4096
+    timeout: 120s              # 请求超时，默认 120s
+```
+
+
+## 自动探测模型列表
+
+不想手抄模型 id 时，只填 URL 和 key，让网关去扫：
+
+```bash
+# 只探测，不写任何东西
+curl -X POST http://127.0.0.1:8080/api/sources/discover \
+  -H "Authorization: Bearer sk-gw-…" -H "Content-Type: application/json" \
+  -d '{"base_url":"https://api.vendor.com/v1","api_key":"sk-…"}'
+# → {"ok":true,"base_url":"…","endpoint":"","models":["gpt-x",…],
+#    "image_models":["gpt-image-2"],"models_path":"/models","latency_ms":1387,…}
+
+# 探测后直接落库
+curl -X POST http://127.0.0.1:8080/api/sources/discover/apply \
+  -H "Authorization: Bearer sk-gw-…" -H "Content-Type: application/json" \
+  -d '{"base_url":"https://api.vendor.com/v1","api_key":"sk-…","name":"vendor"}'
+```
+
+WebUI 源编辑框里也有「自动探测模型」按钮：填好 URL 和 key 点一下，列表自动
+填好，仍需点保存才生效。
+
+几点值得知道：
+
+- **URL 形态不用猜。** 厂商对「`/v1` 放 base 还是放 path」没有共识，探测会
+  依次尝试若干候选并返回答对的那个，同时给出归一化后的 `base_url` +
+  `endpoint`（`endpoint` 平时留空，因为 openai adapter 自带 `/chat/completions`）。
+- **`image_endpoint` 是另一套规则。** 网关的图像默认路径是**绝对**的
+  `/v1/images/generations`，而 chat 默认是相对的。所以 `base_url` 带 `/v1` 时
+  必须显式给 `image_endpoint: /images/generations`，否则图像请求 404。
+  探测会替你填好。
+- **图像模型只看上游自己声明的 modality**，绝不从模型名猜。`gpt-image-2`
+  这类 id 也出现在同时提供对话服务的目录上，猜错会让 AUTO 链选中一个只支持
+  图像生成的模型，其后每一层都被它拖垮。
+- **不会逐模型探活。** 34 个模型的目录跑一轮要花钱且耗时数分钟，`/models`
+  是足够便宜的信号；模型是否真能应答留给正常请求去发现。
+- **对已存在的源，必须显式 `replace_models: true`** 才会覆盖模型列表。重新
+  探测顺手抹掉为 AUTO 链手工调过的 priority，是最难排查的一类数据丢失。
+- **`api_key` 留空表示沿用已存值**，不会把凭据清空。
+
+
+`config.yaml`、`runtime.json`、`master.key`、`adapters/` 均不提交版本库（见
+`.gitignore`），请随备份带走——`master.key` 丢失后运行时密文无法解密。
+
+运行文件生成在 `-config` 所在目录：`adapter_dir` / `runtime_file` 自动指向
+配置文件旁边的 `adapters/` 与 `runtime.json`，从任意工作目录启动都可用。
+
+运行时文件（`runtime_file`）中的敏感字段自动加密：
+
+- 加密算法 AES-256-GCM，格式 `enc:v1:<base64>`。
+- 主密钥来源：环境变量 `MODELROUTER_MASTER_KEY`（64 位 hex）；否则读取
+  `runtime_file` 同目录的 `master.key`；都不存在时首次启动自动生成 `master.key`（0600）。
+- 升级时旧明文文件自动兼容：首次运行正常读取，任何 UI 保存操作触发全文件加密迁移。
+- 注意：**master.key 丢失后密文无法解密**，请随配置一起备份；切勿提交到版本库。
+
+## 网关密钥（多密钥）
+
+网关鉴权采用「多密钥 + 角色 + 模型范围」架构，密钥持久化在 `runtime_file` 的
+`keys` 字段（加密存储）：
+
+- `gateway_keys` 配置只是**初始 admin 密钥种子**：首次启动迁移为运行时 admin
+  key，之后不再参与鉴权管理。
+- **重要：首次启动后请在 WebUI「密钥」页更换管理员密钥**——初始密钥明文写在
+  `config.yaml` 里（每次安装随机生成），继续使用存在被盗风险；用新密钥登录后删除初始密钥。
+- WebUI **密钥页**可创建/删除密钥；每个密钥可指定 `admin`（管理全部）或
+  `user`（仅看自己的 key）角色，并配置**模型范围**（模型 + 源 + token 配额 +
+  重置周期）。
+- 客户端用任意一个已授权的密钥明文作为 Bearer（`Authorization: Bearer <key>`）。
+- 删除密钥即从运行时存储移除，立即失效。
+
+### 密钥用量配额
+
+**配额按模型单独设置**：每个密钥的 `models[]` 里，每一条模型范围各自带一份
+token 配额与请求数配额。一个模型用满只影响该模型，同一密钥的其它模型照常工作。
+
+```yaml
+keys:
+  - key: sk-gw-<hex>
+    role: user
+    name: agent-alice
+    models:
+      - model: deepseek-v4-flash
+        token_quota: 1000000   # 本周期内该 key 用这个模型的 token 预算
+        req_quota: 20000       # 本周期内的请求次数
+        period: nhour          # "" | hour | week | month | nhour
+        hours: 6               # 仅 nhour
+      - model: AUTO
+        token_quota: 5000000   # AUTO 也是一条独立配额
+        period: day            # ← 这种写法会被拒绝（词表只有 hour/week/month/nhour）
+      - model: kimi-k3        # 未列配额 = 无限
+```
+
+- **没有「整钥总配额」**：这是刻意的设计。整钥总额会让「把 A 模型的额度挪给
+  B 模型」变成一次全局重分配；按模型独立计费则每个模型各自可控，运维可以
+  看出哪个模型吃掉了预算。
+- `period` 词表：空 = 永不过期（累计总量），`hour` / `week` / `month` = 固定窗口，
+  `nhour` + `hours` = 自定义小时数。**拼错的周期在写入时就被拒**，不会静默变成
+  永不过期。
+- 配额严格按密钥隔离，且**同一密钥内按模型隔离**：A 密钥用满 `m1` 不会消耗
+  B 密钥的额度，同一密钥的 `m2` 也不受影响。
+- 配额统计含聊天、流式、生图，跨重启从审计日志回放（保留 40 天，覆盖最长的
+  month 窗口）。
+- 配额耗尽返回 **429 + `Retry-After`**（`rate_limit_exceeded`），消息里点名是哪个
+  模型用满了，客户端可等窗口重置后自动恢复；模型越权才是 403。
+  **admin 密钥永不受配额限制**（其 scope 上的配额也不强制），避免把管理员
+  锁在门外。
+- 窗口用量按整点小时分桶统计，实际释放比配置窗口最多晚 1 小时（配额宁可晚释放
+  也不超发）。
+- `PUT /api/keys/{key}` 提交 `models` 即同时提交它们的配额（配额就是 scope 的一部分，
+  不存在会与模型列表脱节的第二份预算）。显式 `0` = 解除该模型的限制。
+
+#### 配额拒绝 vs 容量拒绝：两种「拒绝」含义不同
+
+配额在**入口**检查，不占用任何上游槽位，因此是廉价拒绝；容量不足则要走
+`busyWait` 有界等待后才返回 503。实测（容量 8、0.6s/请求、100 并发）：
+
+| 情况 | 状态码 | 延迟 | 是否打到上游 |
+|---|---|---|---|
+| 配额用尽（`req_quota` 50 → 100 并发） | `429 rate_limit_exceeded` + `Retry-After` | **19–21ms** | 否 |
+| 容量打满（同一拓扑，未限配额） | `503 upstream_error` | ~2.6s（`busyWait`） | 超出部分否 |
+
+客户端因此可以区分「等窗口重置」与「等上游腾出容量」：前者只需等待，后者
+通常该降并发或换源。
+
+#### 配额的开销
+
+配额桶按 (密钥, 模型, 整点小时) 分桶保留 40 天，实测（AMD 7840HS）：
+
+- 窗口查询按窗口长度而非保留总量扫描：1h 窗口 49ns、24h 窗口 55ns、
+  30d 窗口 3.9μs（此前全扫保留总量，960 桶时 5.9μs）。
+- 记录一条请求：283ns、3 分配（与引入配额前相同，分配来自 ring buffer）。
+- 内存：生产形态（7 密钥 × 8 模型 × 2 源 × 满 40 天 retention）约 **3.7MB**。
+  按源 pin 的 `source::model` 桶**惰性创建**——只有当某条配额真的 pin 了
+  某个源时才维护，否则每条记录多写一份桶，在 20 密钥 × 8 模型 × 3 源下会
+  多占 18MB。
+  代价：配置 pinned 配额之前的历史用量无法事后按源拆分，所以 **pinned 配额的
+  首个窗口可能少算**。
+
+```bash
+# 配额耗尽时客户端看到（点名了具体模型）
+HTTP/1.1 429 Too Many Requests
+Retry-After: 2100
+{"error":{"type":"rate_limit_exceeded","message":"token quota exceeded for \"deepseek-v4-flash\" (5000000/5000000)"}}
+```

+| 插件（可选） | `/etc/modelrouter/plugins/`（需在配置里设 `plugin_dir`） |
+| 主密钥 | `/etc/modelrouter/master.key`（0600） |
+| systemd unit | `/etc/systemd/system/modelrouter.service` |
+
+`deploy.sh` 会在以下情况**中止**而不是"看起来成功"：
+
+- 部署后二进制起不来、或新配置 `-check` 不通过；
+- 凭据无法解封（`master.key` 丢失 / 与配置不匹配）；
+- 检测到改名前的 `/etc/llmsproxy`，但新配置尚未建立（否则会部署出一个
+  没有 key、没有源的空实例，所有请求都被拒）。
+
+## 2. 发行包安装
+
+三个产物由 `packaging/core-dist.sh` 生成到 `cmd/build/dist/`：
+
+```text
+modelrouter_<ver>_amd64.deb
+modelrouter-<ver>.x86_64.rpm
+modelrouter-<ver>-linux-amd64.tar.gz
+```
+
+deb / rpm 安装后：
+
+```bash
+sudo systemctl enable --now modelrouter
+sudo journalctl -u modelrouter -f
+```
+
+tar 包内只有：`modelrouter`、`config.example.yaml`、`modelrouter.service`、
+`migrate-to-modelrouter.sh`、`adapters/`。
+
+**发行包不含业务插件**（仓库只保留 `billing` / `usage` 两个与厂商无关的示例）。
+它们保留在仓库中作为可选扩展，需要时手工放入 `plugin_dir`，网关不会自动安装、
+覆盖或删除。这是有意的：插件属于运维资产，生命周期不与内核绑定。
+
+首次启动会在 `/etc/modelrouter/config.yaml` 生成一份**随机 admin key** 的配置，
+key 打印在启动日志里。发行包不预置任何可用 key（历史上曾因此泄露过一个真实的
+`sk-gw-local-0001`）。
+
+## 3. 目录与权限
+
+- `/etc/modelrouter` 是唯一的读写根（systemd unit 用 `ProtectSystem=strict` +
+  `ReadWritePaths=/etc/modelrouter` 固化这一点）。
+- `master.key` 必须 0600。当前 unit 以 root 运行：降权到普通用户需要先把
+  `master.key` 交给该用户并统一目录属主，否则服务会"带着明文落盘继续跑"，
+  失败只留一行日志——这是独立变更，不要和加固混在一起。
+- `plugin_dir` 由运维维护；插件自带的状态文件也在其中。
+
+## 4. 从 llmsproxy 迁移
+
+二进制、配置目录、服务名、环境变量已统一为 `modelrouter`：
+
+| 旧 | 新 |
+|---|---|
+| `/usr/local/bin/llmsproxy` | `/usr/local/bin/modelrouter` |
+| `/etc/llmsproxy/` | `/etc/modelrouter/` |
+| `llmsproxy.service` | `modelrouter.service` |
+| `LLMSPROXY_PLUGIN_DIR` | `MODELROUTER_PLUGIN_DIR` |
+| `LLMSPROXY_XDISPLAY_BASE` | `MODELROUTER_XDISPLAY_BASE` |
+| `LLMS_PROXY_MASTER_KEY` | `MODELROUTER_MASTER_KEY` |
+
+迁移脚本**默认 dry-run**，复制而非移动，旧目录永不删除：
+
+```bash
+sudo ./packaging/migrate-to-modelrouter.sh          # 预演（逐条打印将做什么）
+sudo ./packaging/migrate-to-modelrouter.sh --apply  # 执行
+```
+
+它做五件事：复制状态目录并改写配置里的旧绝对路径、复核 `master.key` 0600、
+安装新二进制（旧文件保留）、由旧 unit 生成新 unit（改写 ExecStart /
+WorkingDirectory / ReadWritePaths）、复制 `/usr/share` 资源；最后跑
+`modelrouter -check` 并 `systemctl daemon-reload`。
+
+确认新服务可用后，再手工清理旧布局（脚本不会删）：
+
+```bash
+sudo systemctl disable --now llmsproxy.service
+sudo rm -f /etc/systemd/system/llmsproxy.service
+sudo rm -rf /usr/local/bin/llmsproxy /etc/llmsproxy /usr/share/llmsproxy
+```
+
+回滚（不需要旧文件被删）：
+
+```bash
+sudo ./packaging/migrate-to-modelrouter.sh --rollback --apply
+```
+
+**读取侧兼容**：旧配置路径与旧环境变量仍被接受，所以"先换二进制、后改 unit"
+这种顺序不会立刻失效。但写入永远落在新路径，迁移完成后不要两台布局混用。
+
+## 5. 部署后验证清单
+
+```bash
+# 1) 进程与监听
+systemctl status modelrouter --no-pager
+ss -ltnp | grep modelrouter
+
+# 2) 鉴权生效（无 key 必须 401）
+curl -s -o /dev/null -w '%{http_code}\n' http://127.0.0.1:8080/v1/models
+
+# 3) 带 key 能列出模型
+curl -s -H "Authorization: Bearer $KEY" http://127.0.0.1:8080/v1/models | head -c 400
+
+# 4) 真实请求走通（证明 LuaJIT 适配器路径未被打断）
+curl -s -H "Authorization: Bearer $KEY" \
+  -d '{"model":"AUTO","messages":[{"role":"user","content":"hi"}]}' \
+  http://127.0.0.1:8080/v1/chat/completions | head -c 400
+
+# 5) 仓库文件与生产文件一致（部署脚本的收尾检查）
+sha256sum /usr/local/bin/modelrouter build/modelrouter
+```
+
+第 4 步失败但第 3 步成功，通常是适配器或上游凭据问题，不是部署问题：
+查看 `journalctl -u modelrouter -n 100`。

+# 实现与完整特性
+
+> 本文档由 README 拆分而来：架构来源与完整特性清单（README 只保留摘要）。
+> 返回 [README](../README.md)。
+
+## 实现
+
+统一 OpenAI 兼容网关：把多个上游 LLM 源（DeepSeek、Qijiar、OpenAI、Anthropic、Gemini、
+Groq、Mistral、Ollama、KimiCode…）通过 **Lua 适配器** 做协议转换，对内网暴露
+一个标准 `OpenAI Chat Completions` 接口（`/v1/chat/completions` + `/v1/models`），
+支持单次结算、SSE 流式、**AUTO 模型路由**与**多模态**透传。
+
+从上游多源 LLM 适配层
+（`internal/agent/api/provider.go` + `internal/lua/adapters/*`）抽离而来并独立演进。
+
+## 特性
+
+- **多源**：一个进程内配置任意多个上游源，按请求的 `model` 自动路由。
+- **AUTO 模式**：`default_model: AUTO` 时按优先级页保存的 AUTO 链档位逐档调度并发请求。
+- **统一输出**：所有源对外都是 OpenAI 格式（含 `reasoning_content`、`tool_calls`、`usage`）。
+- **生图**：`POST /v1/images/generations`，`kind: image` 的模型独立路由。
+- **多模态**：`content` 数组（`image_url` 等）在多源间无损透传，Anthropic/Gemini/Ollama 自动转换。
+- **LuaJIT VM**：基于 golua 绑定的 LuaJIT，每个适配器独立 VM + worker 池，安全并发。
+  池是 **弹性** 的：`Σ max_concurrent` 只是上限而非预分配，状态按需创建、空闲时自动回收，
+  因此空载网关几乎不持有 Lua 状态（启动 0 个）。
+  - 扩容步长由适配器最大并发决定：`clamp(ceil(max/8), 1, 8)`，且仅在**真实并发争用**
+    （所有现有状态均已占用）时批量预热，顺序流量始终只用 1 个状态。
+  - 缩容步长由当前连接数决定：`clamp(ceil(冗余/(1+占用)), 1, 冗余)`——无连接时一轮收到
+    常驻下限，忙时每轮只释放 1 个，保护热路径。WebUI「适配器」页展示实时池指标。
+- **thinking 预算**：请求里的推理开关/预算归一为中立的 `thinking:{enabled,budget_tokens}`，
+  适配器映射到各自协议（Anthropic `thinking.budget_tokens`、Gemini `thinkingConfig`、
+  DeepSeek `thinking.type="disabled"`）。
+- **Lua 适配协议**：每个源挂一个 `.lua` 适配器，完成 `transform_request` /
+  `transform_response` / `transform_stream_chunk` 双向转换，协议差异全在 Lua 层。
+- **签名 / 请求头钩子**：适配器可定义 `build_headers(meta)`，在 Go 发 HTTP 前
+  动态注入/签名请求头——用于云端 API 校验调用方 app（如 KimiCode 只放行特定
+  agent）。提供 `hmac_sha256_hex` / `sha256_hex` / `base64_encode` 等签名辅助。
+- **WebUI**：内置管理界面，可在线查看/新增/编辑上游源与模型、配置 AUTO 优先级链、
+  管理密钥模型范围，写入运行时文件持久化。
+- **密钥加密存储**：运行时文件中的上游 `api_key`、自定义请求头值、网关 key 均以
+  AES-256-GCM 加密落盘（`master.key` 独立 0600，或 `MODELROUTER_MASTER_KEY`）。
+- **实时源探测**：状态页探测各源可达性（`GET {base}/models`，失败回退最小请求），
+  不污染正常调度的退避状态，错误信息在 UI 可悬停查看。
+- **鉴权**：网关自身用 `gateway_keys` 校验客户端 Bearer key；与上游各自的 key 相互独立。
+- **流式**：SSE `chat.completion.chunk`，含角色首包与 `[DONE]` 收尾。
+- **全链路审计**：HTTP 访问日志、登录/配置变更审计、请求记录 CSV 导出、密钥用量统计 CSV 导出
+- **AES-256-GCM 加密存储**：运行时文件敏感字段加密落盘，master.key 0600 权限，支持环境变量注入主密钥

+# 桌面 GUI（Electron）
+
+> 本文档由 README 拆分而来：Headless 与 Desktop 两种产物、构建与运行。
+> 返回 [README](../README.md)。
+
+## 桌面 GUI（Electron）
+
+可选独立产物，面向内网桌面端用户：**内嵌 ModelRouter 核心**（桌面壳形态），
+一键启停、系统托盘常驻、开机自启、静默启动，内容区一比一内嵌完整 WebUI
+（状态/对话/密钥/优先级/源/适配器 六个页面，免登录）。服务器用户继续使用纯 Go 二进制。
+
+### 两种安装包：Headless 与 Desktop
+
+发布到 Release 的安装包分为两类，面向不同用户：
+
+- **Headless（服务器版）**：纯核心二进制（无 Electron），配置驱动，适合服务器、
+  容器、systemd 等无人值守场景。发布包含 `deb` + `rpm`（含 systemd unit、内存调优
+  与示例配置）与 `tar.gz`（二进制 + `config.example.yaml` + `adapters/` + README），
+  Windows 为 `.zip`。
+- **Desktop（桌面版）**：Electron GUI 安装包，内嵌核心，适合个人桌面日常使用。
+
+### 选择 GUI 还是纯后端
+
+| 场景 | 推荐 | 理由 |
+| ------ | ------ | ------ |
+| 服务器 / 内网网关 / 无人值守常驻 | **Headless**（单二进制） | 极轻量（二进制 ~8MB；RSS 随源数量，单源 ~10MB、16 源 ~32–35MB，见[内存占用](#内存占用实测与调优)），零依赖单进程，直接跑在 systemd/任意容器里，远程管理 |
+| 个人桌面日常使用 / 多设备内网共享 | **Desktop**（GUI） | 免登录内嵌 WebUI、系统托盘一键启停、开机自启、静默后台，适合不懂命令行的使用者 |
+| Windows 桌面 | **Desktop** | 纯后端在 Windows 上需自行注册服务，GUI 提供原生托盘/自启体验 |
+| CI 一键出三平台安装包 | **Desktop 打包脚本** | `make gui-*` 系列出 deb/AppImage/NSIS，可进发行流水线 |
+
+两者完全同源：GUI 内嵌的就是纯后端的同一份 `modelrouter` 核心（LuaJIT 版），
+配置/适配器格式完全一致，可随时互换。
+
+### 构建与运行
+
+```bash
+cd cmd/gui
+npm install
+make gui          # 或 npm run dev —— 开发运行（需先 make build 生成 bin/modelrouter）
+make gui-deb      # 本机构建 deb（分享给其它 Linux 用户）
+make gui-dist     # 构建 deb + rpm + AppImage（linux，rpm 需系统 rpmbuild）
+make core-dist    # 构建核心 deb + rpm + tar.gz（服务器版，需 nfpm）
+make gui-win      # 构建 Windows nsis 安装包（本机 mingw + wine）
+make gui-win-docker  # 构建 Windows nsis 安装包（全 docker 自足，含 wine）
+make gui-dist-dir # 仅解包产物（调试用，不产安装包）
+```
+
+产物在 `cmd/build/gui-dist/`：`ModelRouter-<ver>.AppImage`、
+`modelrouter-gui_<ver>_amd64.deb`、`ModelRouter Setup <ver>.exe`（win）；
+核心包在 `cmd/build/dist/`：`modelrouter_<ver>_amd64.deb`、`modelrouter-<ver>.x86_64.rpm`。
+rpm 需系统 `rpmbuild`。每次打包后都会跑 `packaging/verify-dist.sh` 产物体检
+（大小下限门禁——1.3.0 曾因宿主 wine 损坏产出 264KB 的残缺 exe 却没有被拦住）。
+发布时会把产物重命名为 `ModelRouter-Desktop-*`（GUI）与 `ModelRouter-Headless-*`（纯后端）
+两类上传到 GitCode Release。
+
+#### Windows 打包（docker 固化方案，推荐）
+
+`make gui-win-docker` 一步完成：交叉编译核心 + NSIS 打包**全在 docker 内**，宿主机
+**无需 mingw、无需 wine、无需 node**。镜像内置 wine（含 i386 运行时），修复了
+此前宿主 wine 损坏（缺 syswow64 → `c0000135`）导致产出 264KB 残缺 exe 的问题。
+
+- 构建镜像：`cmd/gui/docker/win-builder/Dockerfile`（`golang:1.25` + mingw-w64 +
+  node + wine32/wine64 + 预编译 LuaJIT windows 版 `lua51.dll` 与 import lib）。
+  LuaJIT 源码取自国内镜像，上游兜底；Go 依赖走 `https://goproxy.cn`。
+- 一键发布：`cmd/gui/scripts/dist-win-docker.sh` —— 核心编译 + electron-builder
+  NSIS 全部在容器内执行（`USE_SYSTEM_WINE=true` 走镜像内的 wine）；electron-builder
+  的 ~400MB 工具链缓存挂到 docker volume，二次构建增量复用。
+- 首次运行自动构建 `modelrouter/win-builder` 镜像（约 5–10 分钟）；已存在则直接复用。
+- 打包完成后自动跑 `packaging/verify-dist.sh` 门禁：exe 低于 5MB / deb·rpm·7z 低于
+  10MB 即失败——残缺安装包不可能再溜进 Release。
+
+```bash
+# 全 Windows 发布（核心重编 + NSIS）：
+make gui-win-docker
+```
+
+### 特性
+
+- **内嵌核心**：自动拉起捆绑的 `modelrouter`（LuaJIT 版），配置/密钥/adapter 存于
+  用户数据目录 `<userData>/profile/`，首次运行自动生成随机 admin key 写入 `keys`
+  （非 seed）并自注入，WebUI 免登录、不会提示"更换初始密钥"。端口可在设置中更改（默认 8787）。
+- **系统托盘**：内核状态点、开机自启/静默启动开关、启停/重启内核、退出。
+- **静默启动**：`--silent` 参数或设置项，启动仅驻托盘不弹窗；首次运行始终显示窗口。
+- **开机自启**：Windows/macOS 用 `setLoginItemSettings`；Linux 写
+  `~/.config/autostart/modelrouter-gui.desktop`，静默开启时自动附加 `--silent`。

+> 返回 [README](../README.md)。
+
+## 内存占用（实测与调优）
+
+内存不是一个定数：它随**配置的源数量**增长（每个源一个 `http.Transport` 与连接池、
+一组健康状态），与运行时长无关。本机实测（Linux x86_64，12 核）：
+
+| 部署形态 | 启动 RSS | 稳态 RSS |
+|---|---|---|
+| 1 源 / 1 适配器（最小配置） | ~4 MB | ~10 MB |
+| 1 源 + 29 MB 历史审计日志 | ~19 MB | ~20 MB |
+| **16 源 / 13 适配器 / 59 模型（本机生产）** | ~28 MB | **~32–35 MB** |
+
+> 历史参考：本项优化前同一生产配置为 **~105 MB**。降幅来自三处：审计日志的**原始记录**
+> 不再常驻内存（约 25 MB；统计聚合仍扫全量，但扫完即释放）、Lua 状态池不再单调增长、
+> 以及下面两个运行时开关。
+
+内存构成（生产实例分段测量，`/proc/<pid>/smaps`）：
+
+| 区域 | RSS | 说明 |
+|---|---|---|
+| Go 堆 | ~14 MB | provider/registry/scheduler 结构 + 连接池缓冲 |
+| 其他匹名（线程栈 / LuaJIT chunk / runtime） | ~12 MB | 与线程数、已加载适配器数相关 |
+| 二进制 text+rodata | ~8 MB | 映射的可执行文件页（只读、可被内核回收） |
+| Go runtime 预留 | ~4 MB | VSZ 上看到的 2 GB+ 是地址空间预留，不占物理内存 |
+| 共享库 | ~3 MB | libc / libluajit / libm |
+
+**两个推荐的部署开关**（只适用于环境变量，无需改代码）：
+
+```ini
+# /etc/systemd/system/modelrouter.service
+Environment=GOGC=50
+Environment=MALLOC_ARENA_MAX=2
+```
+
+- `MALLOC_ARENA_MAX=2`：LuaJIT 的分配走 cgo → glibc malloc，glibc 默认允许 `8×nproc`
+  个 per-thread arena，每个碰到 malloc 的 OS 线程会占用一个（各约 1 MB，且**不归还给系统**）。
+  实测从 8–15 个 arena（约 7–12 MB）降到 **0**。
+- `GOGC=50`：把 Go 堆增长目标减半。**单独使用无效**（省下的堆会立即被更多 glibc
+  arena 吃掉，实测 20.3 → 21.5 MB 反而变大），必须与 `MALLOC_ARENA_MAX` 配合，
+  两者同时开启才降 **~19%**。网关是 I/O 密集型（本机 9 小时仅消耗 1min10s CPU），
+  多出的 GC 周期与它的空闲 CPU 相比可忽略。
+
+> 桌面版（Electron）已在 `cmd/gui/main.js` 里默认为内嵌核心注入这两个开关；手动 export 同名
+> 环境变量可覆盖。如果你用自己的 systemd unit / 容器，建议照上面加上。
+
+可选：`GOMEMLIMIT=48MiB` 作软上限，实测再省 ~1 MB；代价是逐近上限时 GC 转激进，
+温和场景不必开。
+
+## thinking 预算
+
+请求体带 `"thinking": {"enabled": false}` 时关闭推理；`"thinking": {"enabled": true,
+"budget_tokens": 4096}` 指定预算。内核只定义这个**中立**语义字段，映射到具体协议由
+适配器负责（Anthropic `thinking.budget_tokens`、Gemini `thinkingConfig.thinkingBudget`、
+DeepSeek `thinking.type = "disabled"`）。内核不再向适配器泄漏 `disable_thinking` /
+`extra_body` 这类私有字段。

+
+前节的自定义挂载点只能回答**由插件计算出来的内容**（`{status, headers, body/json}`）。
+若插件自己起了一个 TCP/HTTP 服务（典型：服务端浏览器栈 + noVNC），客户端就需要
+**字节级转发**，包括 **WebSocket 升级** —— 前者做不到。
+
+为此声明 `prefix = true`，handler 每次请求返回一个**回环目标**：
+
+```lua
+plugin.http = {
+  { path = "myplugin/proxy/:session", method = "GET", prefix = true,
+    roles = { "admin" }, handler = "proxy" },

+  end
+  return { proxy = "http://127.0.0.1:60100" }
+end
+```
+
+规则：
+
+- **只能返回 `{ proxy = <目标> }`**，没有 `status` / `body`。写了 `status` 会被忽略。
+- 目标必须是 **带显式端口的字面回环 IP**（`http://127.0.0.1:60100`）。
+  拒绝 `https://`、`localhost` 这类主机名、无端口、带 userinfo/path/query 的地址。
+  理由：主机名可能被 hosts / DNS / 代理环境改写；通用能力只接受确定性地址。
+- 路由匹配同前缀下的**所有子路径**，`:param` 仍照常捕获，`req.path` 是完整
+  请求路径，子路径由插件自己从 `req.path` 里切。
+- **鉴权先于代理**：`roles` / `keys` / `public` 语义与普通端点一致。
+- **不转发网关凭据**：`Authorization`、`Cookie`、`api_key` 都不会传给后端服务。
+- **拒绝跨站**：`Origin` 与网关自身 host 不一致返回 403。WebSocket 由浏览器
+  发起且自动带 Cookie，否则第三方网页可借管理员会话开隧道。
+- **撤销点唯一**：handler 不再返回目标（或返回 404）即失效，内核不缓存目标。
+

+# 路由与调度
+
+> 本文档由 README 拆分而来：模型路由、AUTO 链、冷却与半冷却、源与适配器、源模板。
+> 返回 [README](../README.md)。
+
+## 模型路由
+
+`/v1/chat/completions` 的 `model` 解析顺序：
+
+1. `source/model` 或 `source:model` 前缀 → 指定源；
+2. 精确匹配某个源的 `model`；
+3. 配置 `default_model: AUTO` 时 → 走优先级页保存的 AUTO 链（见下）；
+4. 否则回落（返回错误）。
+
+任何 OpenAI 客户端，只要 `model` 设为某个源的 `name/任意名`，即可锁定走该源；
+设为 `AUTO`（或网关配了 `default_model: AUTO`）即自动按优先级链选源。
+
+## AUTO 链（优先级页）
+
+AUTO 调度**只**由优先级页保存的规则决定，源配置里的 `models[].priority` 数字不再
+参与调度、也不再显示。**聊天与生图是两套独立的链**，在优先级页面通过「聊天 / 生图」
+按钮切换编辑：
+
+- **聊天链**（`runtime_file` 的 `auto` 字段）：服务 `POST /v1/chat/completions`
+  的 `model: AUTO` 请求；只接受 `kind: chat` 模型，配置在链里的生图槽位会被忽略。
+- **生图链**（`runtime_file` 的 `auto_image` 字段）：服务 `POST /v1/images/generations`
+  的 `model: AUTO` 请求；只接受 `kind: image` 模型。未配置生图链时，AUTO 生图回落
+  到「所有含生图模型的源、按注册顺序」的旧行为，兼容旧配置。
+
+每条规则 = 一个「槽位」：`{ model, source, tier, token_quota, period, hours }`。
+
+- `tier` 表示优先级档位：同一档的模型并排、共享该优先级；档位从上到下递减。
+- 同一模型可配置多个槽位（如 A 源低配 → B 源低配 → A 源高配 → B 源高配），按档位顺延。
+- `token_quota` > 0 时该槽位在重置周期内用满即顺延到下一槽位；`period` 支持
+  `hour` / `week` / `month` / `nhour`（配合 `hours`），空 = 不限。
+- 同 tier 内按「偏好分」排序，失败槽位冷却后自动跳过；冷却 / 配额耗尽 / hard
+  错误会顺延到下一 tier，全部失败时返回 503 并附上每档失败摘要。
+
+## 冷却与半冷却探测（自愈调度）
+
+槽位失败后进入指数退避冷却（5s → 10s → 20s …，上限 **5 分钟**）。冷却不是全时段
+硬闸：
+
+- **前半段完全静默**：刚失败的槽位不接任何流量，避免对故障上游持续施压。
+- **后半段放行 1 个探测**：窗口过半后，同一 `(源, 模型)` 最多允许 **一个** 请求作为
+  探测通过。探测槽数 = `clamp(max_concurrent / 10, 1, 2)`——`max_concurrent: 10`
+  的源恰好放行 1 个探测请求。
+- **探测排在最后**：同 tier 内探测候选永远排在健康候选之后，只有没有正常槽可用时
+  才承接真实流量，因此探测不会抢走可用容量。
+- **探测即真实请求**：成功则立即清零失败计数与冷却，槽位当场回到正常轮询——
+  上游恢复/额度恢复后不必等满整个冷却窗口。失败则重开一个新窗口，下次探测顺延到
+  新窗口的中点，不会连续重试。
+
+分类冷却策略：
+
+| 情况 | 冷却 | 说明 |
+|---|---|---|
+| 传输错误 / 5xx | 5s→10s→20s…，上限 5min | 指数退避 |
+| 401 / 403 凭据错误 | 10min | 换 key 后由下一次探测自动接回 |
+| 429 限流 | 30s 固定 | 「太快」不等于「坏了」，不进指数阶梯 |
+| 配额耗尽（`insufficient_quota` / `余额不足` 等） | 对齐配额窗口，上限 30min | **不进指数阶梯、不涨失败计数**，额度恢复即可用 |
+
+WebUI「优先级」页的槽位健康标签会区分 `冷却` / `待探测` / `探测中`，悬停可看窗口
+起点、探测放行时刻与完全恢复时刻。
+
+## 源（Source）与适配器（Adapter）的关系
+
+- **源** 是到某个上游的连接描述：`name`、`base_url`、`api_key`、模型列表与优先级。
+- **适配器** 是协议转换逻辑（Lua 脚本）：把统一 OpenAI 格式请求转成上游原生格式，
+  再把上游响应/流式分块转回统一格式。
+- 一个适配器可被多个源复用（如 `openai.lua` 同时服务多个 OpenAI 兼容站点）；
+  同一个源也可以切换不同适配器（改 `adapter` 字段即可）。
+- 源决定“连谁、暴露哪些模型”，适配器决定“怎么对话”——二者在 `sources[]` 条目中
+  通过 `adapter` 字段关联。
+
+加载流程（`internal/core` 的 `Core` 负责装配）：
+
+1. 启动时 `lua.NewVM(adapter_dir)` 加载全部适配器：内置适配器（编译期 embed）+
+   `adapter_dir` 下的同名覆盖文件；内置文件写在代码内，覆盖文件要求更高优先级。
+2. `config.Load` 读取 `config.yaml`，`config.NewStore(runtime_file)` 读 WebUI 改动的
+   运行时源，二者按名称合并成完整源列表。
+3. `rebuildRegistry` 为每个源创建 `provider.Provider`（持有目标适配器），并按源的
+   并发上限配置适配器 worker 池**上限**（不预分配，见下）。
+4. 请求进来时 `Registry` 按 `model` 路由到 Provider，Provider 调适配器
+   `transform_request` → HTTP 发送 → `transform_response` / `transform_stream_chunk`。
+
+WebUI 上的"新增/编辑源"、"上传 Lua 适配器"、"改 AUTO 优先级链"与"密钥模型范围"
+都即时生效（写入运行时文件或 `adapter_dir` 后重新装配，无需重启）；直接编辑
+`config.yaml` / `adapter_dir` 下的文件则需要重启进程才会重新加载。
+
+在 WebUI 删除源/适配器时：运行时（WebUI 创建）的源与 `.lua` 文件会真正移除；
+`config.yaml` 中定义的基源无法改写配置文件，采用删除标记隐藏（重启后仍隐藏），
+在 UI 里重新添加同名源即可恢复。
+
+## 源模板（多 key 负载均衡）
+
+多个上游 key 共享同一套配置（URL / 适配器 / 模型列表 / 并发 / rpm）时，逐一复制
+整段 source 太冗余。**源模板**保存除 `name` 和 `api_key` 以外的全部源字段，
+从模板一键创建多个仅 key 不同的源，天然支持多 key 负载均衡（每个展开源独立调度、
+独立冷却、独立健康状态）。
+
+- WebUI「源」页右上角「**模板管理**」按钮：列出全部模板，可编辑 / 删除 / 新建。
+- 添加源弹窗右上角两个按钮：
+  - **从模板创建** → 选模板 → 表单自动填充（name + key 仍需你填）；
+  - **存为模板** → 把当前表单非 key/name 字段存为新模板。
+- 模板持久化在 `runtime_file` 的 `source_templates` 字段，与运行时源一样热管理，
+  改完即时生效。模板本身不含密钥，可以安全共享 / 纳管。
+
+模板不会自己变成源——它只是「配方」。真正承担流量的是从模板创建出来的、带 key
+的具体源。
