Clients that rely on the spec for validation or SDK generation may break if they treat this enum as exhaustive, and any generated SDK code that exposed these as named constants will no longer compile. Note: the underlying API endpoints may still accept these strings at runtime — the removal is from the spec\u002Fenum definition only.","2026-06-15T17:00:25.265Z"]
