notes:
- 'The dominant change class is model add/remove, and removals are hard: models are pulled
  with a "migrate to an alternative" instruction and no stated notice period or sunset
  window. A caller pinning a model ID is the party carrying that risk.'
- 'The changelog page lists entries newest-first but two blocks (the carina-60b/removals
  block, and a 2025-12-26 block placed after 2025-12-23) are out of chronological order on
  the published page. Recorded as published, without correcting the provider''s ordering.'
