note: >-
  Derived from the Maintenance Connection Swagger 2.0 securityDefinitions, then upgraded from the
  published auth pages for each Accruent product surface. Accruent runs four different auth models
  across its portfolio; only Maintenance Connection publishes its scheme in a machine-readable
  contract, and even there the basic scheme is DEFINED but never APPLIED to any of the 255
  operations (no top-level or per-operation security[] block), so a generator reading the spec
  alone would emit an unauthenticated client.

    HTTP Basic. The Authorization header carries base64("ConnectionKey:APIKey") after the "Basic "
    prefix, where the Connection Key identifies the Maintenance Connection database and the API key
    is issued by Accruent for that database. A missing or malformed header returns 401 Unauthorized;
    a non-SSL request also returns 401.

gaps:
- The Maintenance Connection spec defines `basic` but applies it to zero of 255 operations.
- No OAuth 2.0 or OpenID Connect anywhere in the published Accruent API surface.
- No documented key rotation, expiry or scoping model for the Basic ConnectionKey/APIKey pair.
