It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it.

When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles.

When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

Do not wait for or poll the background timer. When you receive the actual background completion notification, use native Agent (not T3 delegate_task), subagent_type general-purpose, run_in_background=true, description \"held queue native probe\", with prompt: \"Synthetic task, no file changes. Make 60 separate foreground Bash calls strictly sequentially, exactly one echo per call: echo child-step-1 through echo child-step-60. No loops, no background tools. After all sixty calls reply exactly PROBE_17885_OK.\" Then immediately end the wake turn without waiting for the child.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it.

When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification. If neither arrives, I'll say so instead of acting as though one did.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:21.732Z","updatedAt":"2026-10-27T14:25:21.732Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:f02fcd7a-82dc-4e5b-9d5c-d7936b697024","role":"assistant","text":"The background completion notification arrived, so I'm launching the child agent now.","attachments":[],"streaming":false,"createdAt":"2026-10-27T14:25:23.786Z","updatedAt":"2026-10-27T14:25:23.786Z"},{"createdBy":"agent","creationSource":"provider","id":"message:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","threadId":"74118d15-f3d3-46c2-8c4d-1b388d337651","runId":"run:thread:74118d15-f3d3-46c2-8c4d-1b388d337651:ordinal:4","nodeId":"node:provider:claudeAgent:native-item:a49c8a7a-06ab-4878-9c87-d79311f89686","role":"assistant","text":"The background timer finished and I've launched the child agent \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\".

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2. When the child's completion arrives, I'll reply `CHILD_ACK_17885` with its result.\n\nI won't fabricate either notification.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\". Its prompt will ask for 60 sequential `echo child-step-N` Bash calls and the exact reply `PROBE_17885_OK`. I'll then end that wake turn immediately without waiting for the child.\n2.

It is a synthetic scheduler check, and I made no file edits.\n\nFirst I started a background Bash command, a Node one-liner that prints `BACKGROUND_17885_DONE` after 30 seconds. It was assigned the task ID `bsxffupea`, and its output goes to a file under the session's tasks directory. I haven't read that file or polled it.\n\nThen I ran a foreground Bash command, a Node one-liner that prints `FOREGROUND_17885_DONE` after 26 seconds. It returned with that string, as expected.\n\nThe two timers are close in length on purpose. The foreground call blocks for 26 seconds, and the background timer needs 30. The background command started first, so it should finish only a few seconds after the foreground call returns. That makes it likely to finish around when this turn is wrapping up. The probe seems designed to test how the scheduler handles a background completion that arrives right as a turn settles. A turn that has ended is idle, so the completion notification should wake the session.\n\nI'm not holding the turn open for the background timer, and I'm not polling it. You asked me not to wait on it, so I'm ending the turn here.\n\nThere are two steps left, and both depend on real notifications arriving:\n\n1. When the actual background completion notification arrives, I'll launch a native Agent with `subagent_type` general-purpose, `run_in_background=true` and the description \"held queue native probe\".
