+name: guanghu-feishu-glp
+description: 晓在飞书向京东零点原核递送只读问答或查询世界规则版本时使用；包含GLP信封、HTTP客户端与服务器接收器。普通文档编辑或现实执行任务不适用。
+---
+
+先读同目录 PROFILE.hldp 和飞书办公室的原话瞄点。该目录是可单独复制的技能包，包含 contract.mjs、client.mjs、receiver.mjs 和测试；服务器部署来源是已核字节包。
+
+从本技能目录运行：
+
+    node client.mjs build 问题.txt 本任务原生会话号 本任务工单号 > request.json
+    node client.mjs send request.json https://本人配置的服务/v1/glp
+
+发送需在私有环境提供 GUANGHU_GLP_TOKEN，不能写入技能、仓库、文档或日志。服务地址必须由用户的部署配置明确给出；本包没有可自动使用的公网端点。当前只做京东隔离验证，飞书收发适配器尚未接通。飞书端若无执行本脚本的工具，需要后续桥接器提供等价HTTP调用；阅读技能本身不会产生工具能力。
+
+REQUEST 表示只读问题；build 命令第四个参数 SYNC 表示只查询公开规则发行版本。SYNC返回可核验版本与哈希，不自动采纳规则，更不是完整人格脑同步。GLP请求只送入外部问题入口，不冒充冰朔本人语言，不写零点或晓的脑。
+
+ACK-RECEIVED是收到；RESPONSE承载结果；ACK-EXECUTED是已完成本次只读查询。失败返回ACK-FAILED，不能把收到写成执行成功。一次HTTP返回这些独立阶段，不提供立即流式ACK。网络重试复用同一份 request.json 和 message_id；相同编号改内容会拒绝。过期后重新生成请求；进程重启不保证去重延续，禁止拿本包执行不可重复的现实动作。
+
+checksum只证明字节一致，不是身份签名；发送主体范围由独立传输凭据约束。本工程剖面使用空signature。需要人类身份、学习、写入或现实动作时走相应系统的既有入口，不能扩展本问答接口。
+
+本地验证：node --test receiver.test.mjs。服务器由操作者设置 GUANGHU_GLP_CONFIG 指向既有私有客户端哈希配置，并以 GUANGHU_GLP_PORT 指定空闲端口运行 node receiver.mjs；接收器始终只绑定127.0.0.1。默认后端固定为本机3931零点ask和3922公开规则manifest，不接受消息指定目标URL、文件路径或命令。
