Summary

Task token and cost totals previously covered only the selected agent, so work delegated to subagents was omitted. Include all recursively related active and archived subagents once per task ID, priced using each agent's recorded model and Fast tier. Keep turn details and events scoped to the selected agent.

Refresh totals when a child log changes, appears, or disappears, even while the parent is idle. Reuse the parent's existing index and cache compact accounting summaries. Report missing or unreadable subagent logs as incomplete totals, preserve explicit read budgets, and show task-wide model request counts in the viewer.

Privacy impact

Descendant discovery uses explicit parent identities and structured subagent activity references. Child logs contribute numeric usage, estimates, and bounded warning counts; transcript content, raw metadata, and paths are not merged into the selected task's response. Source logs and full-detail consent are unchanged. English and Chinese documentation describe the accounting scope.
