Bead bd-o0x: Worker Count Badge - Already Implemented

Summary

The requested feature to add a worker count badge to the TUI header is already fully implemented in the codebase.

Existing Implementation

Location: src/tui/app.ts

1. getWorkerStats() method (lines 124-135)

Returns worker counts by status:

• total: total number of workers
• active: count of workers with status 'active'
• idle: count of workers with status 'idle'
• error: count of workers with status 'error'

2. getHeaderContent() method (lines 140-180)

Builds the header content with:

• "FABRIC - Worker Activity Monitor" title
• Optional filter indicator (when CLI filters are active)
• Worker count badge with color-coded status indicators
  • Green for active workers
  • Yellow for idle workers
  • Red for error workers
  • Format: [2 active | 1 idle] (only shows statuses with >0 workers)

3. updateHeader() method (lines 185-189)

Updates the header content when called.

4. Real-time updates

The header badge updates in real-time via:

• addEvent() method (line 2049): calls updateHeader() after each event
• setViewMode('default') (line 1569): restores header when returning to default view
• Various command handlers: update header with status messages

Example Output

FABRIC - Worker Activity Monitor  [3 active | 1 idle]
FABRIC - Worker Activity Monitor  [2 active | 1 idle | 1 error]

Verification

• All TUI app tests pass (44/44 tests)
• The implementation uses blessed tags for color formatting
• Worker counts are fetched from the InMemoryEventStore via store.getWorkers()
