TUI: Esc cannot interrupt while final-answer text is streaming after status indicator is hidden

Reproduce the issue in the TUI while final-answer text is streaming, then trace the Esc input handling across the transition where the status indicator is hidden. Done means Esc reliably interrupts the active final-answer stream after that transition, with no regression to normal streaming or status-indicator behavior.

What issue are you seeing?

In the TUI, bare Esc stops interrupting a running turn after final-answer assistant text is committed to the transcript.

The task remains running and the TUI remains responsive, but pressing Esc emits no Op::Interrupt. Ctrl+C still interrupts the same turn.

This specifically affects assistant text streaming after a commit tick. It does not require a tool call, queued steer, stalled event loop, or terminal input failure.

What steps can reproduce the bug?

The issue is deterministic in a focused codex-tui test:

#[tokio::test]
async fn esc_interrupts_while_final_answer_stream_is_active() {
    let (mut chat, mut rx, mut op_rx) =
        make_chatwidget_manual(/*model_override*/ None).await;
    chat.thread_id = Some(ThreadId::new());

    chat.on_task_started();
    chat.on_agent_message_delta("Final answer line\n".to_string());
    chat.on_commit_tick();
    drain_insert_history(&mut rx);

    assert!(chat.bottom_pane.is_task_running());
    assert!(!chat.bottom_pane.status_indicator_visible());

    chat.handle_key_event(KeyEvent::new(KeyCode::Esc, KeyModifiers::NONE));

    assert_matches!(op_rx.try_recv(), Ok(Op::Interrupt));
}

Run:

just test -p codex-tui esc_interrupts_while_final_answer_stream_is_active

Actual result:

Starting 1 test across 6 binaries (3249 tests skipped)
FAIL codex-tui chatwidget::tests::status_and_layout::esc_interrupts_while_final_answer_stream_is_active

assertion failed:
Err(Empty) does not match Ok(Op::Interrupt)

The test failed on both nextest attempts.

Control cases pass:

• output_free_esc_interrupt_keeps_prompt_and_opens_blank_composer: Esc emits Op::Interrupt while the status indicator is visible.
• streaming_final_answer_keeps_task_running_state: after text streaming hides the status indicator, Ctrl+C emits Op::Interrupt.

What is the expected behavior?

Bare Esc should interrupt any interruptible running agent turn regardless of whether the transient status indicator is currently rendered.

Hiding the status row while assistant text is streaming should only change presentation; it should not disable the interrupt shortcut.

Additional information

The failure was also reproduced against current source main at 4c4346513342 (codex-zsh-v0.1.0-745-g4c43465133).

The failure is caused by coupling interrupt eligibility to status-row visibility:

• tui/src/chatwidget/streaming.rs intentionally calls hide_status_indicator() when streamed assistant output is committed.
• tui/src/bottom_pane/mod.rs::should_interrupt_running_task() requires both is_task_running and self.status.is_some().
• After the text commit, is_task_running == true but status == None, so the Esc path is rejected before it can emit Op::Interrupt.

Relevant predicate:

self.keymap.chat.interrupt_turn.is_pressed(key_event)
    && self.is_task_running
    // ...
    && self.status.is_some()

Related but not duplicate:

• #17095 concerns pressing Esc to submit a queued steer during a long-running tool call. This report requires neither a tool call nor queued input and reproduces specifically after final-answer text commit.
• #21198 concerns a missing Working indicator after compaction and does not report deterministic Esc interrupt failure.
• #29368 concerns a fully frozen event loop where rendering and all keyboard input stop. Here the TUI remains responsive and only the Esc interrupt route is rejected.

No repository changes are required to reproduce this other than adding the focused regression test above.
