- InstanceEndpoint 取代 Instance.origin（旧数据 init(from:) 读成 .direct， 写盘只输出 endpoint；dedupKey 直通用 origin、中继用 relay:<nodeID>） - RelayWire：Swift 侧重算 contracts/test-vectors.json（CanonicalJSON 手写解析器， 因为 Foundation 的解码器会抹掉'拼写'，而 intent 摘要定义的正是拼写） - NodeTransport 抽象 + DirectTransport / RelayTransport / NodeTransportRouter； DirectTransport 是薄适配，直通路径行为不变 - RelayTransport：信封构造、签名、加密、验签、解密；响应验签失败即丢弃， 四类以上失败各有独立 UpstreamError 分支与用户文案 - DeviceIdentity（沙盒文件 0600，配对时由节点分配 deviceID）、RelayPairing、配对 sheet - 卡片通道徽标 + freshness 副标题；危险写 intent 在发送瞬间生成 - scripts/export-app-routes.swift 生成 vendored 路由表，AppRoutesContractTests 反向守卫 - 测试 78→92：向量互算、迁移（字面量旧 JSON）、配对四类失败、路由器、 传输往返与各类拒绝路径
