fix: keep widget live icon steady while AI is running - #340
Merged
Conversation
The last-output indicator promoted a session to "live" only within a 5s window of its last output chunk, then fell back to "now". An AI session emits output in bursts with quiet gaps between them, so the icon flipped live→now→live every time the model paused — visible churn while the session was continuously working. Drive "live" purely off task state: a session the backend still reports as `running` is live regardless of the gap since its last byte. Non-running sessions keep the relative-time labels (now/Nm/Nh/Nd) and never show live. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

挂件(desk widget)里的时间状态图标在 AI 持续工作时会反复在
live和now之间抖动。根因:
formatLastOutput判定live的条件是「running且距上次输出 ≤ 5 秒」。AI 的输出是间歇成块的——每次静默超过 5 秒图标就掉回now,下一块输出又跳回live。会话状态一直是running,但图标在持续工作期间来回翻转。修复
live改为纯由 task state 驱动:后端仍报running的会话即为 live,与「距上次输出多久」解耦。非 running 会话保留相对时间标签(now/Nm/Nh/Nd),且永不显示 live。LAST_OUTPUT_LIVE_WINDOW_MS(5s 窗口常量),无残留引用。null(不渲染图标),行为不变。取舍
纯 running 即 live 意味着 AI 卡死 / 等网络 / 被限流时(状态仍
running)图标也会一直亮 live。这是「绝不抖动」换来的代价;若日后「假活跃」碍事,可增量加一个较长静默阈值降级,不影响本版。验证
