Problem

Stopping native background subagents leaves their question cards waiting. The child root ends, but each question has its own execution node: its runtime request, node, and card remain pending/waiting/waiting.

Change

The existing recursive Stop cleanup now reads pending child requests, cancels requests owned by runless native child nodes, and interrupts their nodes and cards. Requests attached to user runs on the same child thread stay pending.

Scope and approval

A focused obvious-bug fix: Stop already interrupts this native child and its root, but missed the separate request nodes. This is the native-child counterpart to #30695, whose new request cleanup covers the root thread. This PR is independently based on current main and does not include that PR's changes. Searches for native subagent question/Stop fixes found no other matching implementation.

Verification

Extended the existing background Stop integration case with a runless question and a user-run question on the same child thread. On main 67eebaca23f8, the native question remains pending / waiting / waiting; the test fails. With the fix it becomes cancelled / interrupted / interrupted, while the user-run question stays pending/waiting/waiting.

Approvability

Verdict: Approved at 02f2a79

Macroscope's review found this PR approvable — Stop now closes pending native-subagent questions and approval cards, including when task records settle out of order. Cleanup is scoped to the affected subagents and stopped runs, preserving unrelated user work.

Walkthrough

Stop settlement now handles pending requests associated with native subagents across child and parent threads. It also ends eligible provider-native subagent records. Tests cover native pre-interruption states and descendant commands when the parent turn is active or completed.

Changes: Native subagent Stop settlement

Layer / File(s)	Summary
Load and settle native subagent requests apps/server/src/orchestration-v2/Orchestrator.ts	The child-thread query loads pending runtime requests. Settlement checks child and parent threads, cancels requests owned by the interrupted subagent, interrupts active request nodes and matching waiting cards, and ends eligible provider-native records.
Resolve provider turns for interruption apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts	When no active context directly matches the requested provider turn, interruptTurn searches active contexts’ approval owners for that turn.
Verify Stop settlement states apps/server/src/orchestration-v2/BackgroundWorkStop.integration.test.ts, apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts	Integration tests check request, node, and turn-item states across native pre-interruption modes and child-question locations. Adapter tests cover descendant interruption when the parent turn is active or has completed.

Change: Bug fix

Suggested reviewers: juliusmarminge, bil0000

Merge Risk: Moderate · up to 02f2a

Stop now cancels pending native subagent questions after the parent finishes. In one recovery case, a completed root found through an active child is not marked as stopped, so a late-starting sibling subagent can still begin running after Stop. One new test may also fail intermittently because it can assert before the child interruption is recorded. Fix both before merging.

Full details: Title check

Explanation

The title "fix(server): Stop closes native subagent question cards" follows conventional commit form and names the main change: Stop now interrupts pending question cards of native background subagents. The raw summary and objectives confirm the change centers on Stop cleanup of native child requests, nodes, and cards. The title is specific and does not use vague terms.

Full details: Description check

Explanation

The description follows the template sections (Problem, Change, Scope, Verification) and fills each one with specific content. Problem explains the stranded question cards after Stop. Change explains the recursive cleanup and which requests are cancelled. Scope links a related PR and states why it is a focused bug fix. Verification gives the exact test commands, before/after statuses, and states what was not checked (no native provider runtime capture, no independent review). The template asks for the model and harness, and the author includes that line. The Scope section does not link a tracked issue for the bug, and it gives a reason for omitting one only indirectly, so this is a minor gap rather than a missing section.

Verified in a real dev environment

verified on linux with chrome/playwright, the real dev web client and codex gpt-6.1-sol. created a project pointing at a real git repo and created threads/provider turns through the app, without mocks or seeded fixtures.

on github/main (d6c1d17793), stopping a native child awaiting command approval stopped the child but left its approval actionable. the original pr head (be64152ff1) also left that approval pending. with a completed parent, stop additionally failed to reach the background child.

pushed 02f2a79c3b to the existing fork branch. it finds the completed parent through its live child, cancels child-owned approvals projected on the parent, and handles task/timeline settlement arriving in either order. re-ran the real app: both active-parent stop and completed-parent background stop remove approval controls and restore the composer. approving a native child's command still completes: its stdout and the parent's answer were native-child-approved.

Not verified

native child question cards could not be exercised end-to-end with codex 0.164.0: its question tool rejects child calls as root-only. the existing integration cases cover runless child questions and preserving user-started child runs, but those paths were not proven with a real provider. native ios/android clients, electron shell behavior, macos/windows, and other providers were not exercised on this linux vm.

Wait for the child interruption event before the completed-parent assertions.

In the completed-parent case, the root terminal is already recorded before the interrupt. The awaitTerminal(1) call after interruptTurn returns immediately. The child interruption updates are queued but not yet recorded in harness.events. The assertions that follow can read stale running records and fail intermittently. Wait on the recorded child interruption event itself.

Suggested fix

         yield* harness.awaitTerminal(1);
+        yield* harness.until(() =>
+          harness.events.some(
+            (event) =>
+              event.type === "turn_item.updated" &&
+              event.turnItem.type === "command_execution" &&
+              event.turnItem.nativeItemRef?.nativeId === INTERRUPT_CHILD_COMMAND_ITEM &&
+              event.turnItem.status === "interrupted",
+          ),
+        );

Mark the recovered completed root as stopped.

If the fallback recovers a completed root through an active child, Stop never marks that root in terminalizedNonCompletedNativeTurns. The root is absent from activeTurns, so the interrupt loop skips it and active-lineage finalization cannot mark it.

A registered sibling whose turn/started arrives after Stop then passes the ancestor guard in emitSubagentProviderTurnStarted. The adapter registers that sibling as running instead of interrupting it.

Mark the recovered lineage root as stopped before processing descendants. This lets the existing ancestor guard reject delayed starts.
