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",
+          ),
+        );
         assert.equal(
           harness.terminalEvents()[0]?.status,
           parentCompleted ? "completed" : "interrupted",

Review comment at @apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts at line 6408:
In the completed-parent test after interruptTurn, await the recorded interruption update for INTERRUPT_CHILD_COMMAND_ITEM before checking terminal and child state assertions; awaitTerminal(1) may return immediately because the parent terminal is already recorded. Use harness.until with a predicate over harness.events that matches the child command_execution update with interrupted status.

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.

Review comment at @apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts at line 7975:
Mark the recovered lineage root as stopped before processing descendants in the fallback recovery path, using the existing stopped-turn tracking mechanism. Locate this logic near the approvalOwnerCodexTurn mapping; ensure the root is recorded even when absent from activeTurns so emitSubagentProviderTurnStarted rejects delayed sibling starts through its existing ancestor guard.
