  function handleSubtaskDelete(args: Record<string, unknown>) {
    const db = getDb();
    const rawIds = args.ids;
    const ids = Array.isArray(rawIds) ? rawIds as number[] : [rawIds as number];
  
    const getStmt = db.prepare('SELECT * FROM subtasks WHERE id = ?');
    const delStmt = db.prepare('DELETE FROM subtasks WHERE id = ?');
  
    const deleted = db.transaction(() => {
      return ids.map((id) => {
        const row = getStmt.get(id) as Record<string, unknown> | undefined;
        if (!row) throw new Error(`Subtask ${id} not found`);
        delStmt.run(id);
        logActivity(db, 'subtask', id, 'deleted', null, null, null, `Subtask '${row.title}' deleted`);
        return { id, title: row.title, deleted: true };
      });
    })();
  
    return deleted.length === 1 ? deleted[0] : deleted;
  }
