  description: Record the runtime semantics that are shared across every Snowflake REST contract but stated in none of them.
  update:
    x-runtime-semantics:
      error-envelope: application/json { message, code, error_code (deprecated), request_id } — not RFC 9457
      request-id-header: X-Snowflake-Request-ID (uuid) on every response
      pagination: showLimit / fromName query parameters plus an RFC 8288 Link header; the body is a bare array with no paging envelope
      idempotency: declarative via createMode (errorIfExists|ifNotExists|orReplace) and ifExists — there is no Idempotency-Key header
      auth-type-header: X-Snowflake-Authorization-Token-Type must accompany Authorization and name the credential kind
      rate-limit-signalling: 429 with no Retry-After and no RateLimit-* headers; client-side jittered backoff from ~2s
      dry-run: not supported anywhere in the Snowflake REST API
