What issue are you seeing?

Codex Desktop repeatedly shows macOS desktop notifications asking for approval to run a command. Clicking the notification opens a blank Codex view with a brief plain-text error that flashes too quickly to read. Approving or denying does not resolve it; restarting Codex causes it to happen again immediately.

This appears to come from background ambient suggestion tasks rather than a visible conversation. The approval notification targets a hidden/stale/inaccessible task route, so the click-through opens an error route instead of the relevant approval UI.

Observed logs:
error Conversation state not found conversationId=<redacted>
[desktop-notifications] show approval conversationId=<redacted> kind=commandExecution requestId=1
[desktop-notifications] notification click open notificationId=approval-2

Sentry breadcrumbs showed repeated 403s:
GET https://chatgpt.com/backend-api/wham/tasks/<redacted> -> 403
GET https://chatgpt.com/backend-api/wham/tasks/<redacted>/turns -> 403

Background task prompt seen in logs:
Generate 0 to 3 ambient suggestions for this local project...

Example requested commands:
pwd
rg --files <project> | sed ... | head -n 200
git log --oneline --decorate -n 15

Expected:
Clicking an approval notification should open the relevant approval UI, or Codex should avoid showing desktop approval notifications for background/ambient tasks whose conversation/task is not accessible in the app.

Privacy:
Local usernames, project paths, task IDs, conversation IDs, and request IDs have been redacted.

What steps can reproduce the bug?

I just open the app and the notifications start coming in.

What is the expected behavior?

I shouldn't get random notifications for approval that don't go anywhere.
