note: >-
  QC Ware's CURRENT first-party SDK — promethium_sdk, which also installs the `promethium`/`pm` CLI — is NOT
  published to public PyPI. Its own README sends users to the API tab of the authenticated Promethium settings
  page (https://app.promethium.qcware.com/settings/) for the pip install command, which indicates a private or
  token-gated index. `pypi.org/pypi/promethium-sdk/json` and `/promethium_sdk/json` both return 404, and the
  unrelated `promethium` package on PyPI is a third-party statistics library by another author (do not confuse
  them). The only first-party QC Ware packages on a public registry belong to the LEGACY Forge product and were
  last released in 2022. No npm, Maven, NuGet, RubyGems, Packagist or crates.io packages were found.

  note: >-
    Checked pypi.org for `promethium-sdk` (404) and `promethium_sdk` (404); not on public PyPI, so no registry
    metadata endpoint answers and neither version nor release date can be read. Install command is published
    only behind the authenticated Promethium settings page. Import path is `promethium_sdk.client.PromethiumClient`.
    Installing it also provides the `promethium` (alias `pm`) command-line tool — see cli/qc-ware-cli.yml.

    "The python client for QC Ware's Forge SaaS quantum computing product." Forge is QC Ware's earlier quantum
    computing cloud service; forge.qcware.com no longer resolves for our probe. Last release 2022-05-11 — over
    four years stale, and it does not wrap the current Promethium REST API.

  Every QC Ware package resolvable on a public registry predates the Promethium REST API launch (2023-11-27) by
  at least eighteen months. The SDK that DOES wrap the current API is undiscoverable without an account, so no
  release cadence can be measured for it from outside.
