sendOn在校验目标 socket 之前执行 schema 解析。第 868 行先调用

awaitingOutboxFlush的三条件计算与acknowledgeOutbox的两条件校验不对齐。awaitingOutboxFlush把hello.outboxFlush !== undefined计为等待条件，但批次身份校验只在acknowledgeOutbox为真时生效。结果存在一条中间状态：节点未声明OUTBOX_ACK_CAPABILITY却携带outboxFlush，Host 把它标记为等待，却不跟踪任何批次；此后它只能走 legacy 的outbox_flushed路径，而携带批次身份的完成消息会被 1008 拒绝。测试也没有覆盖这条路径。
apps/host/src/gateway/node-socket.ts#L140-L157：把第 154 行的else if (acknowledgeOutbox && hello.outboxFlush)改为else if (hello.outboxFlush)，使未声明能力却携带批次的 hello 被直接拒绝。apps/host/src/gateway/node-socket.test.ts#L516-L521：在reconcileAfterOutbox断言中补上hello.outboxFlush !== undefined，并新增一个只携带outboxFlush、不携带pendingOutbox的用例。🤖 Prompt for AI Agents

Summary
Adds a durable, application-wide notification system for Fleet sessions, orchestration activity, review requests, failures, and permission requests. Notifications survive Host restarts and reconnects, remain deduplicated across retries, and provide consistent in-app, browser, and sound delivery.
Notification model and persistence
Notification sources
Creates and resolves notifications for:
Notification creation is integrated with session event persistence and orchestration settlement so state changes and their corresponding notifications remain consistent.
Preferences
Lifecycle notification preference resolution follows this precedence:
Top-level sessions inherit the application setting. Dependency workers and reviewers default to quiet unless explicitly enabled. Preferences can be changed from session controls and reset to inherited behavior.
Notification center and delivery
Reliable Node reconnect delivery
Adds an acknowledged Node outbox protocol so session events generated while the Host is unavailable are not removed until the Host confirms the exact flushed batch.
Review feedback addressed
The follow-up commit tightens reconnect and notification correctness, including flush identity validation, event ownership and retry classification, atomic notification creation, stale permission cleanup, retention processing, preference updates, and reconnect behavior.
