  API Releases pages for Origination, Closing, Post-Close and Selling), the Future API Updates page, https://sf.freddiemac.com/tools-learning/system-status,
  and the info.version of each contract in openapi/
versioning:
  scheme: major version in the URL path, plus a semver info.version inside each contract
  evidence: 'Path versions observed in servers[]: /v1, /v2, /v3 (Resolve Retention is /singlefamily/v3/...,
    Resolve Valuation & Pricing /v2, Resolve Workout Options /v1). info.version values span 1.0.0 to 4.0.0.'
  note: The portal's own swaggerVersion metadata and the contract's info.version disagree on several APIs
    - Loan Import is listed as 1.0.0 in the catalog and declares 4.0.0 in the spec; Resolve Workout Options
    is listed 1.0.0 and declares 1.3.0. An agent reading the catalog and an agent reading the contract
    see different version numbers for the same API.

  machine_readable_note: Freddie Mac also ships a System Availability API - documented in the Origination
    API Playbook (sf.freddiemac.com/docs/pdf/api-playbook.pdf, p.13) - returning current application status
    (Operational / Degraded / Full Outage), maintenance status and up to 168 hours of history for Loan
    Product Advisor. It is NOT in the public developer-portal catalog, so no contract for it could be
    harvested.
