    The extended document is the LF Energy TROLIE community specification, not an
    SPP-authored contract. SPP's "SPP LEP/TROLIE API Data Exchange Guide" v1.0
    (2024-11-08) directs implementers to it and publishes no base URL of its own;
    the spec's servers block carries the standard's placeholder host. This
    overlay records that provenance and the SPP-specific access reality on top of
    the untouched spec — it never mutates the harvested original.

      Specification placeholder host. SPP publishes no production base URL for its
      LEP implementation — its own guide writes every example against
      https://<baseURL>/. A participant receives the endpoint through SPP
      onboarding, not from public documentation.

      Declared by the community specification. SPP hosts no OAuth authorization
      server for this API and publishes no token URL; the effective SPP scheme is
      certificate-plus-UAA. The 15 scopes are the standard's vocabulary, captured
      in scopes/spp-scopes.yml.
