 云端控制面使用独立的 `software_node_enrollments` 与 `software_nodes`，不复用用户外部系统连接。管理员创建的一次性注册码具有 128 bit 随机熵，数据库只保存 SHA-256 摘要；节点注册在行锁事务中校验有效期、预期名称和允许能力，成功后原子消费。每个节点获得独立高熵 Token，数据库只保存 bcrypt 强哈希，明文仅在注册响应出现一次。
 
+专业软件采用“共享能力契约 + Node adapter”边界。仓库根目录 `software-contracts/*.json` 是语言无关的声明式事实源，描述 capability、请求 JSON Schema、输入额度、输出 manifest、feature 与最低 adapter 版本；Core 启动时自动发现契约，只负责身份、账本、调度、传输、摘要与最终发布，不包含 Origin 或其他软件的操作分支。Windows Node 是可信宿主，负责持久化 job 目录、下载/上传、恢复、取消和 adapter 注册；adapter 才负责探测具体软件、二次语义校验并执行。adapter 可以是 Node 内置 .NET 实现，也可以由固定 runner 启动任意语言的受信进程；进程只接收 job 目录并通过 `state.json`、`terminal.json` 与固定输出目录交接，不把 Python、COM 或某个 SDK 写入通用协议。当前 Origin adapter 的执行体恰好是固定 Python Worker，这是实现选择而非平台契约。
+
+扩展现有 capability 的 feature 时修改共享契约、对应 adapter/Worker 和测试，不修改 Core 调度与 Job 生命周期；增加新专业软件时新增契约，并在目标 Node 安装包的单一 adapter registry 注册实现。Cloud 会自动获得校验、工具 schema、输出发布和能力发现；Node 的注册能力、配置校验与界面展示也从 registry/契约派生。当前 Node 仍按整机单执行槽保守串行，未来只有真实并行软件需求出现时，才把 slot 账本升级为 per-capability 租约，而不改变 Job 协议。
+
 Node 通过 `Authorization: Bearer` 与 `X-Node-Id` 建立 `/v1/software-nodes/connect` WebSocket。进程内 Connection Manager 保证同一节点单活，新连接关闭旧连接；`hello`/`heartbeat` 更新版本、容量、软件健康与最后在线时间。管理员禁用节点时先持久化禁用态，再关闭现有连接；断线收尾不得覆盖禁用态。当前单活只覆盖单 Web 进程，生产启用多实例前必须增加 Redis/PG fencing 或将 Node API 固定路由到单一控制面实例。
 
 第二阶段已增加 `software_jobs`（专业软件任务）账本与 `origin.plot@v2` 的 offer/accept 骨架。用户只能在本人 task 下以幂等键提交固定 schema；云端规范化请求并记录 SHA-256，按当前进程真实在线、能力匹配、健康且有空闲 slot 的 Node 创建短期 offer。Node 再次校验 schema、图形类型和输出格式，使用 write-through、flush 与原子 rename 先落本机任务目录，再回 `job_accept`；重复 job 只有 digest 一致才接受。过期或发送失败的 offer 回到队列，lease、Node 和 digest 不匹配的响应被拒绝。Node 接收后云端进入 `dispatched` 而非 `running`，并将 slot 降为 0；只有固定 Worker 真正启动后才进入软件无关的 `software_running`，具体软件和操作由 capability/request 表达。

+- **08-14 / Unreleased / 专业软件契约与语言无关 adapter 边界**:将 capability 请求 schema、输入额度、输出 manifest、feature/adapter 版本要求和兼容运行时集中到 `software-contracts/*.json`；Core 自动发现契约并通用完成校验、工具 schema、调度、上传发布，不再包含 Origin 分支。Windows Node 以单一 adapter registry 派生注册能力、配置校验、界面和运行时上报，通用 Host 只处理 job 目录协议；adapter 可由 .NET 内置或固定进程以任意语言实现，Origin 的 Python Worker 仅是当前实现。调度同时按 feature/adapter 版本选节点，并跳过队首暂不可执行 Job。专项 82 项 unittest、Python 编译、Ruff 致命规则、diff 检查与 .NET build 通过；全量 605 项仅 3 个数据库集成模块因显式测试库未迁移、缺少 `users` 表而未通过，未连接或写入生产 DB。
+
 - **08-14 / Unreleased / Origin 统一图型契约扩展**:`origin.plot@v2` 保持单一入口，`series[]` 增加 `z/y_error` 数据角色并由 `plot.type` 判别校验，在兼容既有 XY 请求的同时新增 column、bar、grouped_column、y_error、contour、surface_3d、ternary、heatmap；规则热图在 Worker 内拒绝缺格、重复坐标、非等间距和非有限数值。云端、Agent 工具、Node 二次校验和固定 Worker 已同步，专项 61 项 unittest、Python 编译与 .NET build 通过，未连接或写入生产 DB。
 
 - **08-14 / Unreleased / Windows Node 输出上传收敛与诊断**:恢复中的成功任务优先向云端重放完成确认，已发布结果不再重新打开可能被 Origin 占用的 OPJU；文件共享冲突按 0.5/1/2/5 秒有界退避，本地完成标记使用可跨心跳复用的固定 pending 文件，只重试重命名以避开系统程序对每个新文件的重复扫描，并按 Job 写入带阶段、产物、重试次数和 HRESULT 的 1 MiB 轮转诊断日志。同步修正本机更新时间早于接收时间的展示边界；相关 45 项专项 unittest、.NET build 与 diff 检查通过，未写入生产 DB。

 Web 用户登录后，文件栏 Job 中心会聚合本人最近任务。活动任务约 4 秒刷新一次，空闲时降为约 30 秒；停止已派发任务是协作取消，状态先显示“正在停止”，Node 在线时立即接收，断线后在下次连接或心跳时重放。Agent 可调用 `software_capability_list`、`register_artifact`、`software_job_submit`、`software_job_status` 和 `software_job_cancel`。Origin 输入必须是 artifact：已有 UUID 可直接提交，普通 task 文件先逐个用相对路径登记；登记不会发布聊天交付卡片。提交工具接收 `inputs`、`operation`、`outputs`，支持 1–16 个输入、跨输入系列和多个显式输出，只创建固定 v2 schema 的持久任务，不会阻塞当前对话等待完成。成功状态提供 `output_dir`，Agent可在该目录内搜索并分析；正式输出的 artifact 带 `software_job_id`，供结果卡和产物详情展示来源。Node 输出上传的逐任务诊断日志位于 `%ProgramData%\Zcbot\WindowsNode\jobs\<job-id>\logs\node-output-upload.log`；日志包含上传阶段、产物文件名、重试次数和 Windows `HRESULT`，单文件达到 1 MiB 后轮转一份 `.1`，不记录 Node Token 或认证请求头。
 
+专业软件契约位于 `software-contracts/*.json`，Core 会在启动时自动发现。新增 feature 时更新对应契约与 Node adapter；新增软件时新增契约，并只在 Windows Node 的 `NodeAdapterRegistry.CreateDefault` 注册已安装实现。通用协议不要求 adapter 使用 Python：实现可为 .NET 内置代码或由固定 runner 启动的任意语言受信进程；Origin 安装器创建 Python 3.12 runtime 只服务当前 Origin adapter。
+
 注册配置写入 `%ProgramData%\Zcbot\WindowsNode\node.json`；Token 使用 DPAPI `LocalMachine` 加密，ACL 仅允许注册账号和 `SYSTEM`。应始终用同一专用 Windows 账号执行统一安装器、注册并运行 Node。当前 MVP 以该账号的登录后计划任务启动，不安装 Windows Service。
 
 直接双击 EXE 启动托盘 UI：红点为未注册/身份失效，黄点为连接中，绿点为在线；双击托盘图标打开配置窗。原 CLI 注册入口继续保留，无 UI 模式使用 `Zcbot.WindowsNode.exe run --headless`。
