• src/server.py:112-178 (handler)

  The main handler function for the 'search_authors' tool. It constructs a query to the OpenAlex API /authors endpoint, processes the results into Author objects wrapped in a PageResult, handles pagination, sorting, filtering by institution, and raises appropriate errors.
