  final node = doc.tree[instance];
  if (node is! InstanceNode) return null;
  final c = doc.components.get<SymbolComponent>(node.definition);
  if (c == null) return null;
  SymbolEntry? highest;
  for (final e in library.entries) {
    if (e.key != c.key) continue;
    if (e.version == c.version) return e;
    if (highest == null || e.version > highest.version) highest = e;
  }
  return highest;
