v0.4.5 - Monotonic Stream Revisions & Phase Wake Latching / 流式修订号单调连续性与执行态唤醒锁存

English

Highlights in v0.4.5

• Strict Monotonic Stream Revisions & Terminal Guard: Enforces monotonic assistant stream revisions with a terminal guard (push, settle, abandon), eliminating duplicate frames and preventing RemoteStreamCarrierError: session assistant stream skipped revision in DSH Web UI.
• Active Phase Wake Latching (Steering Guarantee): Latches phase.wakeRequested = true when messages arrive during active execution (phase.kind === "running"), automatically waking the driver upon turn completion so mid-turn user inputs are never dropped.
• Clean Turn Settlement & Signal Reset: Resets AbortController and step counters per turn, ensuring turns end with clean { kind: "completed" } statuses and eliminating spurious UI "处理失败" error markers.
• Event-Sourced V4 Protocol Compliance: Correctly sets producer-owned source kinds on synthetic recovery messages to satisfy strict DSH Session V4 formatting contracts.
• Comprehensive Front-End Contract Test Suite: Ships with dedicated mock tests covering stream monotonicity, idempotent abandonment, V4 source compliance, and phase wake latching.

v0.4.5 版本核心特性

• 流式帧号严格单调递增与终止守卫：引入 AssistantStreamAttempt 状态机终结守卫，杜绝重复发射帧与跳号，彻底消除前端因 RemoteStreamCarrierError: session assistant stream skipped revision 导致的白屏断流。
• 活跃阶段输入唤醒锁存（用户中途追问保障）：当驱动处于执行态（running）接收用户消息时，硬件级强制锁存 phase.wakeRequested = true 并在轮次结算后自动唤醒驱动，根治“正在分析请求卡死、消息被吞”。
• 纯净轮次结算与信号隔离：严格按轮次重新分配全新的 AbortController 并重置步骤计数，结算始终返回标准 { kind: "completed" }，彻底根除前端 UI 虚假弹出的红字“处理失败”。
• 对齐 DSH 会话 V4 事件溯源规范：合成自愈消息均携带生产者所有权标识（source: { kind: "fast-loop" }），100% 满足会话事件规范校验。
• 全套前端洁癖契约回归测试：内置 4 项针对前端挑剔时序的专属 Mock 契约测试，保障版本迭代稳定不破约。
