  The Send Contacts API is the strongest of the Knak specifications: it is the only one
  that declares operationId values and a securityScheme. Observations below concern
  runtime semantics that the spec does not express.

    x-apievangelist-observations:
    - All 11 operations declare an operationId, unlike the other Knak specifications.
    - bulkUpsertContacts is upsert-by-nature and therefore repeatable, but Knak documents
      no general idempotency-key contract, so createContact remains unsafe to
      blind-retry.
    - replaceContactFieldValues is a PUT that replaces the entire field-value set; callers
      must read and merge to avoid dropping values.
    - No rate limit values or rate-limit response headers are published for bulk
      operations.
