useTraceSubscription.ts:
- mergeTraceResults: lastEventLabel 不 fallback 到 events.at(-1)
- mergeTraceSnapshots: lastEventLabel 不 fallback 到 events.at(-1)
- traceSnapshotSignalKey: 不从 events.at(-1) 推导 signal key
server-code-agent-http.ts:
- recordCodeAgentProjectionMetric: status 只读 projection.status
- source 固定为 workbench_read_model
负向源码扫描确认:
- result?.status ?? trace?.status: 消除
- events.at(-1) lifecycle 推断: 消除
- .catch(() => {}) 静默吞错: 消除
- traceStore.subscribe: 仅作为 outbox 不可用时的兼容降级
