## Architecture

### Component Pattern

All components follow Pi's TUI pattern:

```typescript
interface Component {
  render(width: number): string[];  // Return array of lines
  invalidate(): void;                // Clear cache
  handleInput?(data: string): void;  // Optional keyboard input
}
```

### Caching Strategy

Components cache rendered output for performance:

```typescript
private cachedWidth?: number;
private cachedLines?: string[];

render(width: number): string[] {
  if (this.cachedLines && this.cachedWidth === width) {
    return this.cachedLines;
  }
  // ... render logic ...
  this.cachedWidth = width;
  this.cachedLines = lines;
  return lines;
}

invalidate(): void {
  this.cachedWidth = undefined;
  this.cachedLines = undefined;
}
```

### Theme Integration

All components accept `theme: Theme` and use semantic colors:

```typescript
this.theme.fg("accent", text)     // Highlighted text
this.theme.fg("success", text)    // Positive status
this.theme.fg("warning", text)    // Warning status
this.theme.fg("error", text)      // Error/critical
this.theme.fg("dim", text)        // Muted/helper text
this.theme.fg("border", text)     // Borders/separators
```

### Keyboard Handling

Use `matchesKey()` for consistent keyboard detection:

```typescript
import { matchesKey, Key } from "@mariozechner/pi-tui";

handleInput(data: string): void {
  if (matchesKey(data, Key.up)) {
    // Handle up arrow
  } else if (matchesKey(data, Key.enter)) {
    // Handle enter
  } else if (matchesKey(data, Key.escape)) {
    // Handle escape
  }
}
```

---

## Integration with Orchestrator

The Progress Indicator is designed to show real-time updates during parallel sub-agent execution:

```typescript
// In orchestrator.ts (future integration)
async function runParallelSubagents(tasks, onProgress) {
  const scouts = tasks.map(t => ({
    name: t.agent,
    status: "pending",
    progress: 0,
  }));

  const indicator = new ProgressIndicator(scouts, theme);
  ctx.ui.setWidget("dex-progress", (tui, theme) => ({
    render: (w) => indicator.render(w),
    invalidate: () => indicator.invalidate(),
  }));

  const results = await Promise.all(
    tasks.map(async (task) => {
      indicator.updateScout(task.agent, { status: "running" });
      tui.requestRender();

      const result = await runSubagent(task.agent, task.task);

      indicator.updateScout(task.agent, {
        status: "complete",
        progress: 100,
        duration: result.durationMs,
      });
      tui.requestRender();

      return result;
    })
  );

  ctx.ui.setWidget("dex-progress", undefined);
  return results;
}
```

## Next Steps

### Phase 5: Real Integration

Now that the UI components are built and tested, integrate them with actual data:

1. **Wire up `/plan-wizard` to real scout data**
   - Call `orchestrateDailyPlan()` to gather context
   - Pass actual calendar/task/week data to wizard
   - Save generated plan to daily note

2. **Wire up `/review-wizard` to real data**
   - Load completed tasks from today's work
   - Get open tasks from `03-Tasks/Tasks.md`
   - Integrate with commitment-detector for real commitments
   - Save review to daily note

3. **Add Progress Indicator to orchestrator**
   - Show during parallel sub-agent execution
   - Real-time updates as scouts complete
   - Remove mock delays

4. **Week Progress in Footer**
   - Read actual week priorities from `02-Week_Priorities/`
   - Calculate progress based on completed tasks
   - Update footer automatically during session

5. **Career Gauge from Real Data**
   - Read career evidence from `05-Areas/Career/Evidence/`
   - Calculate competency scores from evidence
   - Integrate with `/career-coach` skill

### Phase 6: Polish & Refinement

- [ ] Add search/filter to task board
- [ ] Add task editing modal
- [ ] Customize wizard with user preferences
- [ ] Add visual animations (smooth progress updates)
- [ ] Theme customization
- [ ] Keyboard shortcut hints
- [ ] Help overlays
