按《全平台设备性能监控系统商业化实施方案 V4.0》落地的可运行骨架。 架构主线： - 职责下沉：采集/保活/传输收敛为单一 Rust 核心（rust-core/），经 C FFI 复用 - 网关无状态：连接态/订阅/在线态全部外置 Redis；授权走 PostgreSQL - 存储精简：PostgreSQL + TimescaleDB 承载元数据与时序 - 有界优先：所有缓存/队列/集合均有明确上限与超限策略 - 协议双模：JSON / MessagePack（含数值量化 + 结构指纹缓存） 关键实现： - shared/codec.js MessagePack 量化编解码，稳态上行省 ~24% - shared/protocol.js 信封校验 / 字段白名单 / 版本兼容 / 编码协商 - server/gateway/ 无状态 Socket.io 网关（seq 去重、竞态防护） - server/business/ 账号 / 配对 / 授权 / 审计 - deploy/ nginx + gateway + business + redis + timescaledb 编排 质量验证（共 157 项，bash tests/run-all.sh 一键复现）： - 协议契约 34/34、编解码 64/64、Rust 单测 8/8 - 端到端冒烟 24/24、持久化与重启恢复 24/24 - 断连竞态残留 3/3（100 轮零等待重连零残留） - 泄漏专项：GC 后稳态 heap_used 0.0%，会话与订阅零残留 修复的关键缺陷： - 量化按数值类型判定导致三类静默误缩放 -> 改为按路径位置量化 - 协议白名单/仓储层/建表语句字段名与采集端不一致 -> 静默丢全部数据 - 授权缓存无法跨进程失效 -> Redis pub/sub 广播 + TTL 兜底 - await 期间断连导致在线态永久残留（实测 94% 泄漏率）-> session gone 标记 - 容器 network_mode: host 导致服务名解析失败 -> 改默认桥接网络 - nginx 强依赖证书导致 clone 后必崩 -> 默认 HTTP-only + HTTPS 模板 文档：docs/ 下含方案正文、单页 HTML 报告与 DOCX。
