  a Tokamak Energy client library
note: IMPORTANT DISTINCTION. Tokamak Energy publishes first-party open-source software, but none of it
  is an API client. GSFit is a plasma equilibrium reconstruction library, not an SDK for the content API
  profiled in this repository, and no client library for that API exists in any registry. No SDKs pointer
  is emitted in apis.yml, because sdk_count must not be credited from a scientific computing package.
  The entry below is recorded because it is real, first-party and dated — it is the best available currency
  signal on this company's public software output.

  summary: 'GSFit: Equilibrium reconstruction — Grad-Shafranov equilibrium fitting for tokamak plasmas.'
  first_party_evidence: PyPI author_email is peter.buxton@tokamakenergy.com and project_urls.Repository
    is https://github.com/tokamak-energy/gsfit, a repository in the company's own GitHub organisation.
  repository: https://github.com/tokamak-energy/gsfit
  note: Actively maintained — the source repository was last pushed 2026-08-28, three weeks after the
    0.0.10 release. Version is pre-1.0, which the maintainers signal as unstable API surface.
