## Codegen interpretation and unknowns

- `operationId` identifies the OpenAPI operation; it is not an SDK method name.
- `allOf` is wire-level schema composition. Response adapters must merge inherited and local properties; generated model inheritance/flattening is only a codegen shape, not additional API behavior.
- `x-group-parameters`, `x-enum-varnames`, and `x-enum-descriptions` are generator hints, not business rules.
- Description-only constraints (including conditional fields, precedence, and endpoint-specific behavior) remain verbatim above.
- This OpenAPI snapshot does not confirm cross-cutting error, retry/`Retry-After`, rate-limit, idempotency, delivery, or webhook-signature behavior. Consult the reviewed `runtime.md`; if neither source confirms a fact, do not fill it in.
