//! Application state for TUI monitor
//!
//! Three-panel design:
//! - Top: Waves/Tasks panel showing tasks by execution wave
//! - Middle: Agents panel showing running agents
//! - Bottom: Live terminal output from selected agent
//!
//! Tab switches focus between panels. Space toggles task selection for spawning.

═══════════════════════════════════════════════════════════
RALPH LOOP MODE - Autonomous Task Completion
═══════════════════════════════════════════════════════════

CRITICAL: Your task ID is **{task_id}** (NOT any parent task!)

You are in a Ralph loop. Keep working until the task is COMPLETE.

After EACH attempt:
1. Run EXACTLY: scud set-status {task_id} done
   ⚠️  Use task ID "{task_id}" - do NOT use any other task ID!
2. Verify the task is truly done (tests pass, code works)
3. If something failed, fix it and try again

The loop will continue until task {task_id} is marked done.
Do NOT give up. Keep iterating until success.

When you have genuinely completed task {task_id}, output:
<promise>TASK {task_id} COMPLETE</promise>

DO NOT output this promise unless task {task_id} is TRULY complete!
