# BulkTriageViewComponent

Streamlined interface for triaging multiple findings at once with bucket-based organization.

## Overview

The `BulkTriageViewComponent` provides a triage-focused view with bucket summary cards, one-click bucket selection, and bulk actions.

## Selector

```html
<app-bulk-triage-view />
```

## Inputs

| Input | Type | Default | Description |
|-------|------|---------|-------------|
| `findings` | `ScoredFinding[]` | `[]` | Array of scored findings |
| `selectedIds` | `Set<string>` | `new Set()` | Currently selected finding IDs |
| `processing` | `boolean` | `false` | Whether an action is in progress |

## Outputs

| Output | Type | Description |
|--------|------|-------------|
| `selectionChange` | `EventEmitter<string[]>` | Emits when selection changes |
| `actionRequest` | `EventEmitter<BulkActionRequest>` | Emits when an action is triggered |
| `actionComplete` | `EventEmitter<BulkActionResult>` | Emits when an action completes |

## Action Types

```typescript
type BulkActionType = 'acknowledge' | 'suppress' | 'assign' | 'escalate';

interface BulkActionRequest {
  action: BulkActionType;
  findingIds: string[];
  assignee?: string;      // For 'assign' action
  reason?: string;        // For 'suppress' action
}

interface BulkActionResult {
  action: BulkActionType;
  findingIds: string[];
  success: boolean;
  error?: string;
}
```

## UI Sections

### Bucket Summary Cards
Four cards showing findings grouped by priority bucket:
- **Act Now** (red): 90-100 score
- **Schedule Next** (amber): 70-89 score
- **Investigate** (blue): 40-69 score
- **Watchlist** (gray): 0-39 score

Each card displays:
- Bucket name and color
- Finding count
- "Select All" button
- Selection indicator

### Action Bar
Appears when findings are selected:
- Selection count
- Clear selection button
- Action buttons: Acknowledge, Suppress, Assign, Escalate
- Undo button (when history exists)

### Progress Overlay
Shown during bulk operations:
- Action name
- Progress bar
- Percentage complete
- Items processed count

### Modals
- **Assign Modal**: Email input for assignee
- **Suppress Modal**: Text area for suppression reason

## Usage Examples

### Basic Usage

```html
<app-bulk-triage-view
  [findings]="scoredFindings"
  [selectedIds]="selectedIds"
  (selectionChange)="onSelectionChange($event)"
  (actionRequest)="onActionRequest($event)"
/>
```

### Full Implementation

```typescript
@Component({
  selector: 'app-triage-page',
  template: `
    <app-bulk-triage-view
      [findings]="findings()"
      [selectedIds]="selectedIds()"
      [processing]="processing()"
      (selectionChange)="updateSelection($event)"
      (actionRequest)="handleAction($event)"
      (actionComplete)="onActionComplete($event)"
    />
  `
})
export class TriagePageComponent {
  findings = signal<ScoredFinding[]>([]);
  selectedIds = signal<Set<string>>(new Set());
  processing = signal(false);

  private triageService = inject(TriageService);

  updateSelection(ids: string[]): void {
    this.selectedIds.set(new Set(ids));
  }

  async handleAction(request: BulkActionRequest): Promise<void> {
    this.processing.set(true);

    try {
      switch (request.action) {
        case 'acknowledge':
          await this.triageService.acknowledge(request.findingIds);
          break;
        case 'suppress':
          await this.triageService.suppress(request.findingIds, request.reason!);
          break;
        case 'assign':
          await this.triageService.assign(request.findingIds, request.assignee!);
          break;
        case 'escalate':
          await this.triageService.escalate(request.findingIds);
          break;
      }

      this.selectedIds.set(new Set());
      await this.refreshFindings();
    } finally {
      this.processing.set(false);
    }
  }
}
```

### With Toast Notifications

```html
<app-bulk-triage-view
  [findings]="findings"
  [selectedIds]="selectedIds"
  (actionComplete)="showToast($event)"
/>
```

```typescript
showToast(result: BulkActionResult): void {
  if (result.success) {
    this.toast.success(
      `${result.action} completed for ${result.findingIds.length} findings`
    );
  } else {
    this.toast.error(`Action failed: ${result.error}`);
  }
}
```

## Bucket Selection

### Select All in Bucket
Click "Select All" on a bucket card to select all findings in that bucket.

### Toggle Bucket
Clicking "Select All" when all bucket items are selected will deselect them.

### Partial Selection
When some items in a bucket are selected, the button shows a partial indicator.

## Action Descriptions

| Action | Icon | Description |
|--------|------|-------------|
| Acknowledge | Checkmark | Mark findings as reviewed |
| Suppress | Eye-off | Suppress with reason (opens modal) |
| Assign | User | Assign to team member (opens modal) |
| Escalate | Alert | Mark for urgent attention |

## Undo Capability

The component maintains an undo stack for recent actions:
- Up to 5 operations stored
- Undo restores previous selection
- Toast shows "Undo" button after action

## Accessibility

- Bucket summary has `aria-label="Findings by priority"`
- Select All buttons have `aria-pressed` state
- Action bar has `role="toolbar"`
- Progress overlay announces to screen readers
- Modals trap focus and support Escape to close
- Action buttons have descriptive labels

## Keyboard Navigation

| Key | Action |
|-----|--------|
| Tab | Navigate between elements |
| Enter/Space | Activate buttons |
| Escape | Close modals |

## Styling

```css
app-bulk-triage-view {
  --bucket-card-padding: 16px;
  --bucket-card-radius: 8px;
  --action-bar-bg: #f9fafb;
  --modal-max-width: 400px;
}

/* Bucket colors */
.bucket-card.act-now { --bucket-color: #DC2626; }

.bucket-card.investigate { --bucket-color: #2563EB; }
.bucket-card.watchlist { --bucket-color: #6B7280; }
```
