Implementation

@override
Future<bool> deleteDocument(String documentId) async {
  final doc = _documents[documentId];
  if (doc == null) return false;

  final wasDefault = doc.isDefault;
  final docType = doc.documentType;

  // Remove document and all its versions
  final versionIds = _versions.remove(documentId)?.keys.toList() ?? [];
  for (final vid in versionIds) {
    _versionData.remove(vid);
  }
  _documents.remove(documentId);

  // Auto-assign default to the sole remaining document if needed
  if (wasDefault) {
    final remaining = _documents.values
        .where((d) => d.documentType == docType)
        .toList();
    if (remaining.length == 1) {
      final newDefault = remaining.first;
      _documents[newDefault.id!] = newDefault.copyWith(isDefault: true);
    }
  }

  return true;
