What issue are you seeing?

changing Codex permissions to Full Access while a task is already running does not update the permissions used by the active turn.
The UI shows that Full Access is enabled, but subsequent tool calls continue using the previous restricted permission level. The only workaround is to stop the current task and start it again, which interrupts long-running workflows and may lose progress.

What steps can reproduce the bug?

Start a Codex task with restricted permissions, such as read-only or workspace access.
Allow the task to continue running.
Change the permission level to Full Access without stopping the task.
Observe that the operation is still blocked or triggers an approval prompt.

What is the expected behavior?

Permission changes should apply to subsequent tool calls within the currently active task.

After selecting Full Access, Codex should be able to continue the existing workflow with the new permission level without requiring the task to be stopped or restarted.

Allow permission upgrades to be applied dynamically to the active turn, at least for subsequent tool calls.

Alternatively, the UI should clearly state that the permission change will only take effect after the current task is restarted, rather than showing Full Access as though it is already active.

Additional information

This is particularly disruptive for:

Long-running or multi-step workflows
Tasks that have already accumulated significant context or progress
Runs that encounter an unexpected permission requirement midway through execution
Workflows where restarting may repeat work or produce inconsistent results

Additional context

This request concerns upgrading permissions during an active task. It should not require restarting or discarding the current workflow merely to grant additional access.
