## Shuffle Preview

### Moving {count} items
From: {source.name}
To: {destination.name}

### Items to Move
{for item in items_to_move:}
- [{item.key}] {item.title}
  - Status: {item.status}
  - Dependencies: {item.blocked_by}

### Validation Issues
{for issue in issues:}
⚠️ [{issue.item.key}]: {issue.issue}
   Resolution: {issue.resolution}

### Impact
- Source will have: {source_remaining} items
- Destination will have: {dest_total} items

if not dry_run and not issues:
    for item in items_to_move:
        pm_context.assign_to_project(item.id, destination.id)

        # Also move children

        # Add comment
        pm_context.add_comment(
            item.id,
            f"Moved from {source.name} to {destination.name}"
        )

## Shuffle Complete

### Moved {count} items
From: {source.name} → To: {destination.name}

### Items Moved
{for item in moved:}
✅ [{item.key}] {item.title}

### Updated Dependencies
{for dep in updated_deps:}
🔗 {dep.from_item} → {dep.to_item}
