  Quandela ships a Python-only first-party client stack. Every package is
  published to PyPI from the Quandela GitHub organisation. Searches of npm
  (registry.npmjs.org search "quandela" and "perceval" — 0 first-party hits),
  Maven Central (search.maven.org "quandela" — numFound 0), crates.io
  ("quandela" — total 0), NuGet, RubyGems, Packagist and pkg.go.dev found no
  Quandela-authored library. https://hub.quandela.com/integrate advertises a
  "C SDK" and a "Java SDK" alongside the Python SDK, but neither is published
  to a public registry and no corresponding repository exists in the 15-repo
  https://github.com/Quandela organisation, so they are recorded below as
  advertised-but-undistributed rather than as packages.

    The Python stack is current — perceval-quandela 1.2.4 and exqalibur 1.4.1
    both published 2026-07-02, six weeks before this check, against a Quandela
    Cloud API reporting version v2.8.0-rc4. No abandonment signal on the
    distributed packages. The gap is coverage, not decay: the REST surface has
    59 operations and only the Python SDK reaches it.
