-# Agent Instructions
-
-## Project
-
-MoShiro is a self-hosted network path quality monitor. Backend coordinates Agents and Probes, stores measurements, and serves the REST/SSE API. `web/display` is the read-only overview; `web/admin` manages nodes, tests, and settings.
-
-## Branch and workspace safety
-
-- Treat `main` as the stable release branch and `dev` as the integration branch. Keep ordinary implementation work on `dev` or a feature branch; integrate into `main` through a pull request.
-- A push to `main` builds images only if its commit message contains `[CI]` (for a merged PR, put it in the PR or merge commit title). Without `[CI]` nothing is built; use `[CI SKIP]` to skip the pipeline entirely. When squashing or pushing to `main`, add `[CI]` unless a build is explicitly not wanted.
-- Before editing, inspect `git status`. Preserve pre-existing user changes: do not reset, clean, stash, or include unrelated files in a commit.
-- Do not commit credentials, API keys, registry passwords, or generated runtime data. CI credentials belong in Woodpecker secrets (`zot_secret`, `gitea_token`, `release_signing_key` for signing release manifests, `release_api_token` with the `release` scope). The release signing private key never goes into the repository or the panel; only the public key in `packaging/update/` does.
-- Keep development OCI images in the `moshiro-dev/` repository path and release images in `moshiro/`. Do not let a development build overwrite release tags such as `latest`.
-
-## Project layout
-
-- `backend/src/MoShiro.Backend/`: service entry point and composition.
-- `backend/src/MoShiro.Backend.Api/`: REST endpoints, contracts, and OpenAPI.
-- `backend/agent/`, `backend/probe/`: node applications and their READMEs.
-- `backend/fleet/`, `backend/shared/`: reusable node framework, measurement engine, protocols, and data formats.
-- `web/display/`, `web/admin/`: Vite applications; `web/shared/`: API client, generated types, charts, and shared UI.
-- `packaging/`, `scripts/`, `.woodpecker/`, `docs/`: container/package builds, CI workflows, and project documentation.
-
-## Local development and builds
-
-Requirements: .NET SDK 10 and Node.js/npm. The SDK selection is defined by the root `global.json`; NuGet package versions are centralized in the root `Directory.Packages.props`.
-
-- All .NET projects: `dotnet build MoShiro.slnx -c Release` from the repository root.
-- Backend build: `cd backend && dotnet build MoShiro.slnx -c Release`
-- Backend tests: `cd backend && dotnet test --solution MoShiro.slnx -c Release`
-- Frontend dependencies/build: `npm ci --prefix web && npm run build --prefix web`
-- Frontend style check: `npm run lint:css --prefix web`
-- Local backend: from `backend/`, run `dotnet run --project src/MoShiro.Backend -- --urls http://localhost:5000`.
-- Local web apps: from the repository root, run `npm ci --prefix web` then `npm run dev --prefix web`. The current dev config uses display port 5173 and admin port 5175; `/admin/` is proxied through the display server. Check the Vite configs when working on another branch because ports can differ.
-- After changing API contracts, regenerate/check `backend/openapi/v1.json` and run `npm run gen:api --prefix web` so frontend API types stay aligned.
-
-Follow the user's requested validation scope. Do not start a full tag/release build unless requested.
-
-## CI and releases
-
-CI triggers and image tags can change; inspect `.woodpecker/*.yml` and `docs/deployment.md` before changing or describing them. In particular, check the distinction between `[CI]` main builds, `[SKIP TESTS]`, and version-tag releases in the current branch.
-
-A version tag `vMAJOR.MINOR.PATCH` runs the full cross-platform release pipeline. Development image builds and releases must remain isolated in their respective Zot repository paths.

-# MoShiro
+# Monitor
 
-MoShiro 是一个自托管的**网络线路质量观测工具**。它在若干 Probe（例如家宽出口）与多台 Agent（例如海外 VPS）之间做主动网络测量，只记录逐包、逐事件的原始数据；Backend 保存这些原始数据，推算延迟、丢包、抖动、吞吐等指标，并回答「如果在这条线路上部署某类服务，体验会怎样」；Web 界面用来查看、比较和管理。
+Monitor 是一个自托管的网络线路质量观测工具。它在 Probe 与多个 Agent 之间执行主动网络测量，记录逐包和逐事件结果；Backend 保存原始数据并生成可查询的线路指标，Web 界面用于查看、比较和管理节点。
 
-## 项目边界
+它面向需要比较不同网络出口、评估线路稳定性，或观察特定网络服务体验的场景。Agent 与 Probe 专注于测量和上报；它们不提供远程终端、命令执行或文件管理能力。
 
-**它做什么**
+## 能力概览
 
-- 主动测量：组合 TCP、UDP、TLS、ICMP 等采集积木，只记录时间、序号、大小这类原始事实，**不转发也不记录业务内容**。
+- **主动测量**：组合 TCP、UDP 等测量模块，采集延迟、丢包、抖动、吞吐和连接事件。
-- 线路分析：Backend 从原始数据生成时间序列指标，按服务模型（REALITY、Hysteria2、Minecraft 等）评分并对多条线路排序、对比；模型和指标可以事后重算。
+- **线路分析**：从原始测量数据生成时间序列指标，并比较线路在不同服务模型下的体验。
-- 管理：节点注册与审批、Probe 和 Agent 之间连哪些线路、任务与按需测试、节点版本与更新，都在管理端完成。
+- **节点管理**：通过 Fleet 节点框架处理身份、注册、连接、任务同步和数据上报。
-
+- **实时面板**：展示端查看线路状态和历史趋势；管理端负责节点、任务和系统配置。
-**它不做什么**
+- **自托管**：Backend 使用段文件和 SQLite 保存数据；提供 Linux、systemd 和 OpenWrt 相关部署文件。
-
-- **节点是纯采集器**：Agent 和 Probe 没有终端、命令执行、文件读写和自更新能力，也不加载外部代码。更新由节点宿主机上的更新器完成，节点进程只放面板转来的发布清单。
-- **不是主机监控**：Agent 只上报 CPU、内存、磁盘、网卡流量和运行时长这类只读的汇总数字，不采集型号、主机名、进程和任何 IP；Probe 不上报主机资源。
-- **不暴露地址**：公开接口里没有 IP、城市、ASN；国家和运营商只由 Backend 查询（节点自己不访问任何外部服务）。
-- 暂不包含告警（见文末待办）。
-
-## 信任关系
-
-```text
- 管理员 ── 账号密码（Cookie 会话 + CSRF）或 API 令牌（read · admin · release）──▶ Backend
- 访客   ── 匿名只读，站点设为公开时才可用（没有 IP、城市、ASN）──────────────▶ Backend 公开接口
-
- 节点   ── 加入令牌一次性注册，之后用自己的 ECDSA P-256 密钥签名认证 ───────▶ Backend（只存公钥）
- Probe  ── 用同一把密钥签名建立测量会话 ───────────────────────────────────▶ Agent（只放行面板名单里的 Probe 公钥）
- CI     ── 发布私钥对「镜像 digest 清单」签名 ──▶ Backend 原样转发 ──▶ 节点宿主机的更新器用本机公钥验签
-```
-
-- **Backend 不信任节点上报的内容**：数据按线路隔离存放；节点的身份靠签名，数据库泄露也无法冒充节点。
-- **节点不信任 Backend 的下发**：任务超出节点本机的硬上限（目标网段、码率、包速率、监听端口）就被拒绝；节点不执行任何「执行类」指令。
-- **更新不依赖面板的诚实**：清单必须由发布私钥签名；节点宿主机的更新器用本机公钥验签、只认本机配置的镜像仓库、按 digest 拉取、拒绝旧的 `seq`。面板被攻破也推不出恶意镜像。

-
-- **控制链路（Fleet）**：节点到 Backend 的 `wss` 长连接（`/api/agent/v1/rpc`），JSON-RPC 2.0 信封加二进制通道；挑战加签名认证，`hello` 协商版本和能力，心跳；**期望状态同步**（Backend 下发完整快照，节点调和并回报已应用的版本和被拒绝的条目）；**可靠发件箱**（原始块至少一次投递，按 id 去重）。Fleet 与业务无关，放在 `backend/fleet/`。
-- **业务方法**：`moshiro.*`（按需测试、Probe 断开、事件、主机汇总、更新通知等），状态文档有 `task_set`（Agent 的任务集）和 `probe_agents`（Probe 的 Agent 列表）。
-- **测量数据面**：Probe 到 Agent 的 TLS 控制通道、UDP 和 TCP 数据通道（默认 `7443/tcp`、`7443/udp`、`7444/tcp`）；会话用 `session_id` 和 MAC 认证、不绑定五元组，NAT 映射变化后自动跟随。
-- **REST + SSE**：`/api/public`（展示，可匿名）、`/api/admin`（管理）；OpenAPI 在 `backend/openapi/v1.json`，前端据此生成类型。

-## 如何构建
-
-环境：.NET SDK 10（`global.json` 指定版本）、Node.js 与 npm。在仓库根目录：
 
 ```sh
-dotnet build MoShiro.slnx -c Release          # Backend、Agent、Probe、Fleet、测试和 CI 工具
+cd backend
-npm ci --prefix web && npm run build --prefix web   # 展示端和管理端，产物在 web/display/dist、web/admin/dist
+dotnet build Monitor.slnx -c Release
 ```
 
-本地运行：先在 `backend/` 里 `dotnet run --project src/MoShiro.Backend -- --urls http://localhost:5000`，再 `npm run dev --prefix web`，展示端是 <http://localhost:5173/>，管理端是 <http://localhost:5173/admin/>。
+安装前端依赖并构建展示端和管理端（在仓库根目录运行）：
-
-测试和检查：
 
 ```sh
-dotnet test --solution MoShiro.slnx            # 后端和节点的测试
+npm ci --prefix web
-npm run lint:css --prefix web                  # 前端样式（颜色只能写在主题令牌里）
+npm run build --prefix web
-npm run gen:api --prefix web                   # 后端改了接口之后重新生成前端类型
 ```
 
-Backend、Agent、Probe 以 OCI 镜像发布（Linux amd64、arm64），Agent 和 Probe 另有 Linux glibc/musl、macOS、Windows 的二进制包。NativeAOT 的构建细节、CI 触发规则（`[CI]`、`[SKIP TESTS]`、版本 tag）、镜像路径、容器节点的运行和更新见 [`docs/deployment.md`](docs/deployment.md)；前端见 [`web/README.md`](web/README.md)，后端见 [`backend/README.md`](backend/README.md)。
+前端产物位于 `web/display/dist/` 和 `web/admin/dist/`。NativeAOT 目标平台和 Windows 上使用 AotAnywhere 交叉构建的说明见 [`docs/deployment.md`](docs/deployment.md)。
 
-## 文档
+Backend、Agent 和 Probe 均以 OCI 镜像发布，支持 Linux/amd64 与 Linux/arm64；Agent 和 Probe 另外提供 Linux glibc/musl、macOS 与 Windows 二进制包。容器部署配置见 [`compose.yaml`](compose.yaml)，发布说明见 [`docs/deployment.md`](docs/deployment.md)。
 
-| 文档 | 内容 |
+### 本地运行

-## 测量
-
-- 路由跳数、路径漂移和 trace
-- 握手耗时：TCP 连接耗时，TLS / QUIC 握手耗时（QUIC 目前没有真实握手积木）
-- 网页长截图
-- pcap / eBPF 采集
-
-## 任务与面板
-
-- 单个 Agent 的任务（目前是线路模板加按 Agent 的覆盖，没有只属于某一个 Agent 的独立任务）
-- 原生 webhook 投递；告警（基于 webhook）
-- Agent 和 Probe 的定时重启（可选，例如早上四点）
-
-## 部署
-
-- 后端自动下载前端资源：用 Podman、Docker 部署时，默认拉取最新的前端资源（现在前端要自己构建，镜像里没有）。
-
-## 访客页面
-
-- 人机验证：访客页面要通过验证才能拉数据，前端访问时静默触发。候选 tiago2/cap 和 Cloudflare Turnstile。
-
-## 更新
-
-- 更新遥测（现在面板只有每个节点的「当前更新状态」）
-- **回滚路径的实机测试**：容器节点更新后观察 20 秒、失败回滚，只有单元和脚本测试，没有在真实节点上触发过。
-- **更新的灰度和自动策略**：按标签分批发布；`POLICY=auto` 的长期验证。
-- **纯二进制节点的更新**（`fleet-updater`、`fleet-release`、Windows 服务和 OpenWrt procd 适配器）。设计要点，实现时照这个来：
-  - 信任来自签名：只接受离线发布密钥签名的清单，发布源可以是面板、GitHub Releases 或任意 HTTP 服务；面板被攻破也推不出恶意二进制。
-  - 本地说了算：更新策略（`auto` / `notify` / `pinned:<version>`）和信任的公钥写在节点本地配置里，面板只能「建议」；支持多把公钥以便轮换。
-  - 清单带 `app`、`channel`、`version`、`min_from`、各 RID 制品的 `sha256` 和大小、`key_id`、签名（对规范化 JSON 签名）；本地记录已装过的最高版本，拒绝降级和旧清单重放。
-  - 流程：下载 → 校验 → 解包到 `versions/<v>/` → 原子切换 `current`（Linux 符号链接，Windows 目录联结）→ 重启服务 → 等健康信标确认 → 失败切回旧版本并把该版本标记为坏版本。
-  - 权限分离：更新进程只能写安装目录和重启被管理的服务，读不到节点身份私钥。
-  - OpenWrt：`keep_versions = 1`，下载前检查闪存剩余空间。
-  - 容器节点已经实现的那一套（清单签名、`seq` 防重放、按 digest 拉取、回滚）见 [`docs/deployment.md`](docs/deployment.md)。
-
-## 安全
-
-- **Agent、Backend、Probe 的零信任设计**：目前 Backend 是三者之间的信任中心，需要梳理哪些信任可以去掉。
-- **extension**（Web SSH、TTY、更新遥测，敏感 operator）：设计时必须保住「节点是纯采集器」这条边界，见 [`README.md`](README.md) 的项目边界。
-- 对 UDP 包、控制帧、RawChunk、JSON-RPC 做模糊测试；伪造签名和重放的专项测试。
-
-## 打包
-
-- OpenWrt：procd 脚本、ipk/apk 包、sysupgrade 保留列表，在 aarch64 路由器上长时间运行验证。
-- Windows 服务适配。

-# Fleet：通用节点框架
-
-「很多节点连到一个面板」这类产品都要解决同一批问题：节点怎么接入、怎么证明身份、怎么保持连接、怎么可靠上报、怎么接收配置。Fleet 把这些做成与业务无关的库，MoShiro 是它的第一个使用者；产品只写业务。Fleet 不引用任何 `MoShiro.*`，也不出现产品的名字、端口和协议前缀，由 `ArchitectureTests` 在构建时检查。

-## 设计原则
-
-1. **与业务无关**：产品通过扩展点接入：元数据类型、RPC 方法、发件箱消息类型、期望状态文档类型。
-2. **安全默认值**：Fleet 永远不提供 exec、shell、文件读写、远程下发代码这类方法；节点只响应本地注册过的方法（本地策略 `allow_methods` 还能收窄）；调用对方不支持的方法在本地直接返回 `fleet_unsupported`。
-3. **权限分离**：注册（`fleet-enroll`，一次性）和常驻业务进程是两个进程；常驻进程不含注册代码，也不使用 `HttpClient`。
-4. **NativeAOT**：节点侧只依赖 BCL，泛型扩展点通过产品传入的 `JsonTypeInfo<T>` 序列化，不使用反射。
-5. **更新不在 Fleet 里**：节点进程没有自更新能力。容器节点的签名更新由宿主机上的更新器完成，见 [`docs/deployment.md`](../../docs/deployment.md)；纯二进制节点的更新是待办，见 [`TODO.md`](../../TODO.md)。
-
-## 身份
-
-| 对象 | 算法 | 保存位置 |
-| --- | --- | --- |
-| 节点身份密钥 | ECDSA P-256（BCL 自带） | `<identity_dir>/node.key`（0600）；服务端只保存公钥 |
-| 点对点 TLS 证书 | 自签名 ECDSA P-256 | `<identity_dir>/tls.pfx`；对端按 SPKI SHA-256 指纹校验 |
-| 签名串 | `"fleet|v1|<purpose>|" + 各字段` | 带用途前缀，防止同一个签名在不同场景被复用 |
-
-用途：`auth`（连接服务端）、`peer`（点对点）、`enroll`（注册时的持有证明）。产品可以追加自己的用途，不能占用 `fleet` 保留的。
-
-## 注册
-
-```text
-管理员 ── 创建加入令牌 {labels, max_uses, expires_at, auto_approve} ──> 服务端
-       <── 令牌明文（只返回一次）+ 安装命令
-
-节点：fleet-enroll --server https://panel --join jt_xxx --name jp-1 --identity-dir /etc/myapp
-  ├─ 生成身份密钥和 TLS 证书

-- 同名节点已存在时，新注册进入 `pending`，管理员选择「接管」（旧记录换成新公钥，历史数据保留）或「作为新节点」。
-- 节点状态：`pending`（能连接，但不下发状态、不接收上报）、`active`、`disabled`（拒绝连接）。
-
-## RPC
-
-- JSON-RPC 2.0；方法名 `领域.动作`，`fleet.*` 保留给框架，产品用自己的前缀（MoShiro 是 `moshiro.*`）。
-- 二进制帧 `u8 channel | 正文`：`0`–`15` 框架保留，产品从 `16` 开始。
-- 错误：`error.data.code` 为 snake_case，框架的以 `fleet_` 开头，产品可以扩展。
-- 与传输无关：同一套路由跑在 wss 上，也跑在 TLS 帧（`u32 长度 | u8 类型 | 正文`）上。
-
-| 保留方法 | 方向 | 说明 |
-| --- | --- | --- |
-| `fleet.challenge` / `fleet.auth` | 服务端→节点 / 节点→服务端 | 签名认证（`auth` 用途，nonce 30 秒内有效） |
-| `fleet.hello` | 节点→服务端 | 版本、能力、本地策略摘要、当前时间 → 返回时钟偏差；产品的元数据也放在这里 |
-| `fleet.heartbeat` | 节点→服务端 | 每 10 秒一次，产品可以附加计数 |
-| `fleet.state.sync` | 服务端→节点 | `{version, doc}` → `{applied_version, rejected[]}` |
-| `fleet.outbox.ack` | 服务端→节点 | `{ids[], duplicates[]}` |
-| `fleet.revoked` | 服务端→节点 | 节点被禁用或接管，随后断开 |

-## 连接
-
-```text
-connect(wss) → fleet.challenge → fleet.auth → fleet.hello → 状态同步 → 正常运行
-      ▲                                                                  │
-      └──── 指数退避重连（1 s → 60 s，带抖动；401 或 revoked 时停止重试）◀─ 断开
-```
-
-本地策略：`allow_methods`、`max_frame_bytes`、`max_inflight`。
-
-**可靠发件箱**：产品 `EnqueueAsync` → 有界队列（按字节和条数；满时 `DropOldest` 或 `Reject`）→ 发送 → 服务端收件箱（`IInbox`）持久化后 `fleet.outbox.ack` → 移除。至少一次，按 `msg_id`（UUIDv7）去重；在途数据默认限 4 MiB；丢弃会累计缺口，通过 `OnGap` 通知产品。只在内存里，不落盘。
-
-**期望状态同步**：服务端 `IStateProvider<TDoc>` 给每个节点算 `{version, doc}`，变化时 `NotifyChanged` 推送；节点 `StateHandler<TDoc>` 调和后返回 `{applied_version, rejected[]}`。下发的是**完整快照**，天然幂等，重连后服务端总会重发当前版本。`rejected[]` 带结构化原因（`unsupported`、`budget_exceeded`、`policy_denied`），面板可以直接展示。
-
-## 点对点会话
-
-```text
-节点 A（发起方，如 Probe）── TLS（按 SPKI 校验证书）──> 节点 B（监听方，如 Agent）
-    <── fleet.challenge ──
-    ── fleet.auth（peer 用途，A 的私钥签名）──>
-    B 用服务端下发的对端公钥列表验签（经 state.sync 下发），之后复用同一套 Rpc：路由、二进制通道、发件箱
-```
-
-对端公钥和允许连接的节点由产品通过期望状态下发给监听方，Fleet 只管认证和会话，拓扑由产品决定；UDP、原始 TCP 数据面由产品自己实现，Fleet 只提供会话密钥派生和首帧 MAC 的辅助函数。
-
-## 宿主与服务端抽象
-
-- `ModuleHost`：按依赖顺序启动模块、相反顺序停止，隔离故障，重启时退避。
-- `NodeConfig`：源生成 JSON 读取，环境变量覆盖，启动时校验。
-- `ConfigStore`：常驻进程里**唯一**允许写文件的地方，只能写配置目录，写入原子替换、权限 0600；父目录不存在会创建。
-- `ServiceShell`：SIGTERM、Ctrl+C，systemd `sd_notify`、OpenWrt procd（前台运行）和 Windows 服务。
-- 服务端接口：`IFleetStore`（节点、令牌、公钥、状态版本）、`IStateProvider<TDoc>`、`IInbox`、`INodeEventSink`、`IEnrollmentHook`。MoShiro 把 `IFleetStore` 放进自己的 `moshiro.db`，和业务数据由同一个单写入者写入。

 ```sh
 cd backend
-dotnet build probe/src/MoShiro.Probe -c Release

 发布 NativeAOT 程序需要对应平台的 C/C++ 工具链；`<RID>` 应与构建环境和目标平台匹配：
 
 ```sh
-dotnet publish probe/src/MoShiro.Probe -c Release -r <RID> -p:PublishAot=true

 也可在仓库根目录运行 `bash scripts/publish.sh probe <RID>`，再使用 `scripts/package.sh probe <RID>` 生成部署包。支持平台和安装流程见 [`../../docs/deployment.md`](../../docs/deployment.md)。
