Steps not shown during implementation when a plan has been refined with additional context

What version of the Codex App are you using (From “About Codex” dialog)?

26.311.21342

What subscription do you have?

pro

What platform is your computer?

Darwin 25.3.0 arm64 arm

What issue are you seeing?

When a plan is refined with additional context after initial creation and then implemented, no steps are displayed during implementation in the Codex app. Task tracking is effectively broken for any session where the plan is refined before execution.

What steps can reproduce the bug?

1. Start a session and let Codex generate an initial plan — steps display correctly at this stage
2. Provide additional context to refine the plan
3. Proceed with implementation
4. Observe that no steps are shown during implementation

What is the expected behavior?

Steps should be displayed during implementation regardless of whether the plan was refined before execution.

Additional information

When testing via the SDK, turn/plan/updated events seem to be missing after refinement — which is likely the root cause.
