fix(server): stop jobs a Claude CLI moved out of its process group when the session closes - #34505
Review item 1 was correct: the previous head recorded descendants only on an explicit session close, so a CLI that exited by itself (the issue's reproduction) left a job in its own process group running. A new runner test reproduces that case: a fake CLI starts sleep 600 in a new group via perl setpgrp, then exits after sleep 3 with no close. It timed out on the previous head. Fix in ClaudeAdapterV2.ts: when the CLI is spawned through spawnClaudeProcessGroup and has no agent scope unit (macOS, or Linux without systemd), a tracker runs ps -A -o pid=,ppid=,pgid=,lstart= every second. Each run records descendants of the CLI pid and of jobs already recorded, keyed by pid and start time, so re-parented jobs stay tracked. Closing the session refreshes once more, before the CLI is told to exit. On any CLI exit (orderly, self-exit, crash, SIGKILL on a failed open) polling stops. A final ps adds late children of recorded jobs, but not of the CLI's old pid, which may have been reused. Each recorded process still running with the same pid and start time is SIGKILLed, and a process leading its own group gets its whole group killed. Linux with a systemd scope is unchanged and runs no extra ps. The ps parser is trim().split(/\s+/), linear in line length on adversarial input. Cost: one ps per second for each open Claude session, only where tracking is on. Limits: a job that starts and leaves the tree within one poll interval before the CLI exits is missed, and nothing cleans up after a server crash.
Commit origin/main 7e565c5, on a Linux VM (no macOS worker). macOS's behaviour comes from AgentScope being the no-op default off Linux (apps/server/src/process/agentScope.ts:102). Process groups behave the same on both. 1) I called the real spawnClaudeProcessGroup from apps/server with the reporter's stand-in CLI: a Node script that spawns /bin/sleep 600 with detached:true and exits after 1.5 s. ps -o pid=,ppid=,pgid=,command= showed: while the CLI ran, 35857 35849 35857 /bin/sleep 600 (child of the CLI's group leader, in its own group); 3 s after the CLI exited and onExit had run, 35857 1393 35857 /bin/sleep 600, re-parented to the subreaper (systemd --user; launchd/PID 1 on macOS), still running. 2) I added a test to ClaudeAgentSdkQueryRunner.test.ts that goes through the query runner with the default AgentScope: the fake CLI starts sleep 600 in a new process group (perl setpgrp) holding a FIFO, then the session is opened and closed. The test times out after 120 s because the job never stops. The neighbouring same-group test ('stops what the CLI left running when the session closes') passes.
Evidence
Run the real Claude query runner with the default no-op AgentScope and a synthetic CLI that starts detached sleep 600, then exits after 1.5 seconds. Inspect processes while the CLI runs, three seconds after its exit, and after session close.
Environment on both sides: Linux, macOS no-op-scope lifecycle path; identical driver and synthetic data. Recordings show timestamped command output.
AI-assisted; verified with the tests and tools listed above.
Not shown:
Native macOS execution was not verified: this VM is Linux and the brief prohibits reaching another machine.
A complete running server and client session was not exercised; evidence directly executes the production server query-runner component and real SDK with a synthetic CLI.
The scenario runner was not used because its replay provider bypasses the Claude-specific process lifecycle.
Tests
On the previous head (3d37b31), the new test vp test run src/orchestration-v2/Adapters/ClaudeAgentSdkQueryRunner.test.ts -t "when the CLI exits" failed (timed out after 120 s). After the fix: the full ClaudeAgentSdkQueryRunner.test.ts passed 17/17. -t "own process group" (the close test and the self-exit test) passed 3/3 repeated runs. A temporary variant with the fake CLI exiting after 1.5 s, matching the reviewer's stand-in, passed 3/3 and was reverted. vp run check:changed passed: format, lint, knip 1/2 and 2/2, graphql, typecheck of 3 packages, 3 test files with 373 tests.
The failed-open path (Effect.onError in open) SIGKILLs the CLI without snapshotting its descendants.
On Linux the extra ps snapshot is redundant with the systemd scope; it was kept so the fix doesn't depend on the platform and is exercised by the Linux test.
Force stop (AgentScope.kill) is still a no-op off Linux; it kills nothing outside the CLI's group until the CLI exits.
Each session runs its own ps poll; sharing one process-table read across concurrent Claude sessions would cut the cost but is an optimisation beyond this fix.
Other providers that spawn CLIs (ACP, Pi, etc.) have the same gap on macOS and were not changed.

…ng the session
Reproduces #34459: with the default AgentScope (macOS), a job the CLI
starts in a new process group keeps running after the session closes.
AI-assisted; verified with the tests and tools listed above.
…en the session closes
On macOS the agent scope is a no-op, so a job the Claude CLI started in its
own process group survived the group kill and ran on, re-parented to PID 1,
after the CLI exited. Closing a session now records the CLI's descendants
while it still runs, and once it exits SIGKILLs those that are still the
same process (same pid and start time).
Fixes#34459
AI-assisted; verified with the tests and tools listed above.
Descendants were recorded only when a session closed, so a CLI that exited
by itself still left a job in its own process group running. Without an
agent scope, the CLI's process tree is now recorded every second while it
runs and again at close, and whatever is still the same process (pid and
start time) is killed on any CLI exit.
Fixes#34459
AI-assisted; verified with the tests and tools listed above.
Macroscope's review found this PR approvable — Extends Claude session cleanup to stop descendant jobs that escaped its process group. Tracking is limited to unscoped non-Windows sessions and checks process identity before termination, consistent with existing session-lifetime cleanup.

The Claude adapter tracks process descendants when no agent scope handles cleanup. It refreshes tracking while the CLI runs and stops surviving tracked processes on query close or CLI exit. Unix-only tests cover both cleanup paths.
Changes: Claude CLI descendant cleanup
Layer / File(s)
Summary
Process identity and descendant operations apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts
The spawn result exposes the child PID. The adapter parses process-table rows, discovers descendants, and signals them by process group or PID.
Polling, cleanup, and validation apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAgentSdkQueryRunner.test.ts
When no agent scope is available, the non-Windows path polls descendants and stops surviving tracked processes after CLI exit. Query close refreshes tracking if the process has not exited. Unix-only tests cover cleanup on session close and CLI exit.
The change stops jobs that a Claude CLI moved out of its process group, but cleanup is best-effort. A failed process-table read or a server shutdown right after session close can still leave jobs running. The new exit test can also hang if its tracking scan is delayed. Resolve these before merge, or accept them explicitly.

Explanation
The description is comprehensive and covers the problem, implementation, scope, limitations, reproduction evidence, and focused test results. It does not use the template's exact section headings or provide an explicit maintainer approval comment, but the required information is otherwise substantially present.
Full details: Linked Issues check
Explanation
The implementation satisfies active issue #34459. When no agent scope owns cleanup, ClaudeAdapterV2.ts polls ps, records descendant PID and start time, refreshes before session close, and on CLI exit kills matching recorded processes. It also kills the recorded process group when a recorded process leads that group. The two POSIX regression tests cover session close and CLI self-exit. The issue presents snapshot tracking as a backstop, so the documented polling and server-crash limits do not leave a required coding objective unmet.
Full details: Out of Scope Changes check
Explanation
The current PR also changes behavior unrelated to #34459. The incremental diff adds scheduled-wakeup tracking and publication, steer status handling, Claude launch-file home-path expansion, and Claude process-exit error classification. These changes do not support detached descendant cleanup and are not required by the active issue. The process tracking code and its focused tests are in scope.

Make the fixture distinguish group termination from PID termination.
This fixture has only one job in the new process group. Replacing signalProcessGroup with a signal to that job’s PID would still close the FIFO and pass the test. Extend this case with a child that remains in the job’s process group and holds the FIFO; synchronize its creation so the assertion checks the group signal. As per path instructions, “Test behavior that can break, and extend an existing test or table when it fits.” (raw.githubusercontent.com)

Do not treat a failed final ps read as proof that every job exited.
If the final ps read fails or times out, tracker.stop kills no tracked jobs, even if an earlier poll recorded them. Detached jobs can continue running after the session closes.
Keep the identity check, but retry the read or report that cleanup did not complete.

Await descendant cleanup before completing session close.
The exit listener starts tracker.stop in a detached fiber. session.close does not await that fiber. If the server shuts down after session.close returns but before the final scan and signals finish, the detached job survives a normal shutdown. Retain cleanup completion for this child and join it from close, including when processExited is already true. (raw.githubusercontent.com)

Synchronize CLI exit with a completed tracking scan.
The three-second sleep does not establish that polling recorded the job. If a scan starts before the job and the next scan is delayed until after the CLI exits, cleanup has no recorded job. The test then waits indefinitely for leftoverStopped. Use an observable scan-completion signal before allowing the fake CLI to exit. As per coding guidelines, “Never wait on sleeps or polling.” (raw.githubusercontent.com)

Use a stronger process identity before sending SIGKILL.
lstart records time only to the second on Linux and macOS. If a PID is reused within that second, identity matches the recorded row. tracker.stop can then kill the unrelated process or its process group. Use an OS-native process handle or a stronger creation-time identity for this check. (man7.org)

Remove exited processes from successful snapshots.
Every refresh scans all recorded rows, but tracked never removes exited processes. A long-running session that starts many short-lived commands therefore retains those rows and repeats work for them every second. Prune absent identities after a successful table read. Keep the existing records when ps fails; readProcessTable currently represents that failure as an empty list.

Review item 1 was correct: the previous head recorded descendants only on an explicit session close, so a CLI that exited by itself (the issue's reproduction) left a job in its own process group running. A new runner test reproduces that case: a fake CLI starts
sleep 600in a new group via perl setpgrp, then exits aftersleep 3with no close. It timed out on the previous head. Fix in ClaudeAdapterV2.ts: when the CLI is spawned through spawnClaudeProcessGroup and has no agent scope unit (macOS, or Linux without systemd), a tracker runsps -A -o pid=,ppid=,pgid=,lstart=every second. Each run records descendants of the CLI pid and of jobs already recorded, keyed by pid and start time, so re-parented jobs stay tracked. Closing the session refreshes once more, before the CLI is told to exit. On any CLI exit (orderly, self-exit, crash, SIGKILL on a failed open) polling stops. A final ps adds late children of recorded jobs, but not of the CLI's old pid, which may have been reused. Each recorded process still running with the same pid and start time is SIGKILLed, and a process leading its own group gets its whole group killed. Linux with a systemd scope is unchanged and runs no extra ps. The ps parser is trim().split(/\s+/), linear in line length on adversarial input. Cost: one ps per second for each open Claude session, only where tracking is on. Limits: a job that starts and leaves the tree within one poll interval before the CLI exits is missed, and nothing cleans up after a server crash.Fixes #34459
Reproduction on main
Commit origin/main 7e565c5, on a Linux VM (no macOS worker). macOS's behaviour comes from AgentScope being the no-op default off Linux (apps/server/src/process/agentScope.ts:102). Process groups behave the same on both. 1) I called the real spawnClaudeProcessGroup from apps/server with the reporter's stand-in CLI: a Node script that spawns /bin/sleep 600 with detached:true and exits after 1.5 s. ps -o pid=,ppid=,pgid=,command= showed: while the CLI ran,
35857 35849 35857 /bin/sleep 600(child of the CLI's group leader, in its own group); 3 s after the CLI exited and onExit had run,35857 1393 35857 /bin/sleep 600, re-parented to the subreaper (systemd --user; launchd/PID 1 on macOS), still running. 2) I added a test to ClaudeAgentSdkQueryRunner.test.ts that goes through the query runner with the default AgentScope: the fake CLI startssleep 600in a new process group (perl setpgrp) holding a FIFO, then the session is opened and closed. The test times out after 120 s because the job never stops. The neighbouring same-group test ('stops what the CLI left running when the session closes') passes.Evidence
Run the real Claude query runner with the default no-op AgentScope and a synthetic CLI that starts detached
sleep 600, then exits after 1.5 seconds. Inspect processes while the CLI runs, three seconds after its exit, and after session close.Environment on both sides: Linux, macOS no-op-scope lifecycle path; identical driver and synthetic data. Recordings show timestamped command output.

Tests
On the previous head (3d37b31), the new test
vp test run src/orchestration-v2/Adapters/ClaudeAgentSdkQueryRunner.test.ts -t "when the CLI exits"failed (timed out after 120 s). After the fix: the full ClaudeAgentSdkQueryRunner.test.ts passed 17/17.-t "own process group"(the close test and the self-exit test) passed 3/3 repeated runs. A temporary variant with the fake CLI exiting after 1.5 s, matching the reviewer's stand-in, passed 3/3 and was reverted.vp run check:changedpassed: format, lint, knip 1/2 and 2/2, graphql, typecheck of 3 packages, 3 test files with 373 tests.Not in this change
