From 950785336bb510d9c89195b012e89db1111a3147 Mon Sep 17 00:00:00 2001 From: Julius Marminge <51714798+juliusmarminge@users.noreply.github.com> Date: Thu, 24 Sep 2026 15:32:50 -0700 Subject: [PATCH 1/4] test(server): record Claude background task and subagent lifecycles live Unit tests for Claude background work build frames the CLI never sends: results without terminal_reason, task_started without tool_use_id, SendMessage with agent_id instead of to. This records the flows live instead and replays them through the whole orchestrator. - claude_background_task_wake: a background Bash wake becomes exactly one continuation run; a later user message runs as its own turn. - claude_background_subagent_lifecycle: two background subagents; one wakes the root, one is stopped with TaskStop, then the first is resumed with SendMessage and wakes the root again. - claude_background_task_interrupt: interrupting a turn that owns a background Bash task clears the roster and starts no continuation. The recorder can now wait for several wake turns per prompt (told apart by their task-notification origin, since a wake queued during a turn can run before the next prompt's turn), keeps recording wakes that start right after, and can interrupt after the Nth root tool use.

The adapter's incremental roster fallback admitted every local_bash task, so after the root turn settled those steps were marked wake-eligible: their notifications opened the continuation early and replaced its detail, so the continuation run for the claude_background_subagent_after_root recording said "Sleep 3 seconds then echo SUB_DONE_1" instead of the subagent's summary SUB_FINAL_REPORT. A foreground task blocks its tool call, so it is not background work. The fallback now skips is_backgrounded false; a task moved to the background later still reaches the roster through background_tasks_changed.
