Spec-first
The OpenAPI 3.1 spec at /openapi.yaml is the source of truth. Both SDKs are generated from it; the human docs, Postman collection, and SDK types are kept in lockstep.
Versioning is conservative: v1 is frozen for at least 6 months before
deprecation, and we ship a v2 shoulder-by-shoulder with the old version.
