  Probed public registries (PyPI, Maven Central) and the SigOpt GitHub
  organization (https://github.com/sigopt) for first-party client libraries.
notes: >-
  SigOpt (ML experiment/hyperparameter optimization) was acquired by Intel in
  2020 and its hosted API/platform was subsequently shut down (sigopt.com now
  301-redirects to an Intel corporate redirector; api./app./docs.sigopt.com no
  longer resolve). The client libraries below remain published on their
  registries and in the still-public github.com/sigopt organization, so they are
  recorded as real, first-party historical packages. Most repos are archived;
  the Python client (sigopt-python) and the open-source engine components
  (sigoptlite, libsigopt) are not.
