Problem

A parent could be woken twice with the same delegated task result:

• Restart cuts the delivery run. finalizeDelegatedCompletionDelivery returned every task of a cancelled delivery run to pending, even when the agent had already answered it (assistant message, reasoning, tool calls). After a restart, recovery sent the same completion again.
• The child runs again. When a child ran again on its own (a background-command wake) and replied, the parent got a second Delegated task <new id> (<same title>) [completed] wake. Nothing in it said it followed the earlier task, and it woke the parent even when the reply repeated the result the parent already had.

Reproduced on main 4cb6945dc6 with the new tests in DelegatedCompletionDelivery.test.ts, which drive restart recovery and a background-command follow-up through the orchestrator.

Change

• Cut delivery runs. A cancelled delivery run that already wrote provider output now counts as delivered. That output is an assistant message, reasoning, a plan, a todo list, a file change, a command, a search, a tool call, a question, an approval request, or the run's own native subagent launch. Follow-up task rows the server attaches to that run (app_owned) don't count. A cut run that wrote nothing is still offered again, as before.
• Follow-up wake text. The wake now reads ..., a follow-up of task <id> after the child ran again. The id comes from the child thread's immutable fork origin; no new field is added.
• Repeated results. Some follow-ups are recorded as delivered without waking the parent: ones the child started on its own (a notification or usage-limit resume, with no user message and no parent message on any of the task's runs, steers included) whose status and text equal the last result the child completed. The last result is chosen by completion time. If several results share that time, the follow-up must repeat all of them. A previous result that was disposed doesn't count. A follow-up started or steered by the parent or the user always wakes. task_status still reports the silent follow-up's result.

Not checked: a live server restart against a real provider session. The restart path is exercised through the orchestrator's restart recovery (recoverDelegatedTasks) in the tests above.

This change touches only server delivery bookkeeping and wake text. There is no UI change, so there are no captures.

Walkthrough

The orchestrator now identifies follow-up tasks in delegated-completion messages and avoids another parent delivery for some repeated results. It also uses delivery-run output to determine whether a cancelled run completed its delivery. Tests cover follow-up delivery cases and recovery after interrupted runs.

Changes: Delegated completion delivery

Layer / File(s)	Summary
Follow-up completion context apps/server/src/orchestration-v2/Orchestrator.ts	Delegated-completion details and queued or dispatched wake messages include the task that a follow-up task follows.
Repeated follow-up results apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/DelegatedCompletionDelivery.test.ts	When a self-started follow-up repeats the latest non-disposed result with the same terminal status, the task is marked delivered. Tests cover when repeats are delivered or suppressed, including parent- or user-started and steered follow-ups.
Interrupted delivery finalization apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/DelegatedCompletionDelivery.test.ts	A cancelled delivery run counts as delivered when its turn items show the agent acted, except for app-owned subagent items. Tests cover recovery states for replies, subagents, and questions.

Merge Risk: Low · up to 714c5

The change reduces duplicate delegated-task wakes. One test assertion is looser than it should be and could miss a future regression in the silent follow-up rule. This is a small follow-up and does not block merging.

Explanation

The description covers the Problem, Change, Scope and approval, and Verification sections. It links the issue and gives detailed test results, including what was not checked. It notes AI assistance but does not identify the model and harness requested by the template.

Full details: Linked Issues check

Explanation

Issue #32279 requires correct handling of cut delivery runs, identifiable follow-up wakes, suppression of repeated self-started results, and delivery after parent or user involvement. The previous reviewed code and tests establish these behaviors. The new changes add handling for queued wakes, late acknowledgements, and sibling deliveries. The added tests cover queued-wake acknowledgement, cancellation, settlement, and late reads. No concrete unmet coding requirement is evident.

Full details: Out of Scope Changes check

Explanation

The incremental changes add delegated-completion queue and acknowledgement handling, related projection access, and tests for those paths. The provider handoff and native-goal changes are in the same orchestration flow and can support delegated delivery behavior. The available diff does not establish a concrete unrelated change.

apps/server/src/orchestration-v2/DelegatedCompletionDelivery.test.ts: 1

2673-2678: Trivial · Functional Correctness · Quick win

Assert the exact delivery state in the suppression test.

assert.notInclude(["pending", "claimed"], followup.completionDelivery?.state) also passes when the state is undefined. It passes when the state is "acknowledged" or "disposed" too. The test would then accept a follow-up that was never marked delivered. That is the behavior the production code sets. Assert "delivered" directly.

Proposed fix

-        assert.notInclude(
-          ["pending", "claimed"],
-          followup.completionDelivery?.state,
-          "a self-started follow-up that repeats the last result should not be queued to wake the parent",
-        );
+        assert.equal(
+          followup.completionDelivery?.state,
+          "delivered",
+          "a self-started follow-up that repeats the last result should be recorded as delivered without waking the parent",
+        );

🟡 Medium orchestration-v2/Orchestrator.ts:13137

A background follow-up that repeats an earlier result overwrites an already resolved completionDelivery with delivered, losing a disposed or acknowledged state and potentially its observedByRunId. The repeatsUnprompted override should apply only when the current delivery is unresolved.

Suggested change

	...(repeatsUnprompted && {
	completionDelivery: { state: "delivered", observedByRunId: null },
	}),
	...(repeatsUnprompted &&
	(task.completionDelivery?.state === undefined ||
	task.completionDelivery.state === "pending" ||
	task.completionDelivery.state === "claimed") && {
	completionDelivery: { state: "delivered", observedByRunId: null },

Evidence

Environment for every capture: Linux web app in Chromium, 1440 × 1000 CSS viewport, 2× scale, dark theme. Separate unmodified worktrees ran their own dev servers and fresh synthetic databases with seeding disabled. The uploaded deterministic ACP fixture drives the production provider adapter and MCP delegation tools; its background command is a real shell subprocess. Videos show the product UI, uniformly cropped to remove private sidebars.

Same steps on both commits:

1. Delegate a synthetic check. In thirteen threads, leave its completion delivery unfinished after one of twelve output kinds, or no output. Inspect each, restart its server, then revisit each thread.
2. Have a child return seven checked files while a background command runs. On command completion, let the child repeat its final reply without a parent or user message. Inspect child and parent.
3. Repeat with a changed result of eight files and read the parent's received wake text.
4. Ask the parent to request the same child result, then send the same request directly as the user in the child. Return to the parent after each.

Before	After
d290c1f1	714c5b23
Restart: twelve output kinds duplicate the completion; no-output correctly retries	Restart: twelve output kinds retain one completion; no-output correctly retries
Identical background follow-up wakes parent again	Identical background follow-up is retained without another parent reply
Child command completion → repeated child reply → duplicate parent reply	Child command completion → repeated child reply → one parent reply
Changed result wakes parent without original-task label	Changed result wakes parent with “a follow-up of task … after the child ran again”
Parent-requested repeat wakes parent	Parent-requested repeat still wakes parent
User-requested repeat wakes parent	User-requested repeat still wakes parent

The restart recordings cover assistant message, reasoning, dynamic tool, command execution, file search, web search, file change, task list, proposed plan, provider-native subagent, user-input request, approval request, and the no-output control. Chapter timestamps for every case point to rendered states; navigation and reconnect delays remain in the videos. The walkthroughs include a cut to a later recording of the settled parent view. Every output video was opened and visually inspected before upload.
