  API Evangelist enrichment pipeline. Captures the cross-cutting runtime semantics that
  Sendoso documents in prose but that do not live in any spec, so they can be re-applied
  after the OpenAPI is regenerated from the docs.

          Sendoso publishes no OpenAPI. This document is generated from Sendoso's own
          reference pages; every operation carries an externalDocs URL back to the page it
          came from.

          Sendoso does not handle duplicate payloads. Any order sent to Sendoso is processed
          immediately. POST operations are NOT safe to retry.

    description: >-
      Flag the highest-consequence operation in the API. It spends real money and ships a
      physical object, it has no idempotency, and a 2xx does not mean delivery.

      x-note: >-
        A 200 means Sendoso accepted the order, not that a gift will arrive. Terminal outcome
        arrives asynchronously over webhooks — see asyncapi/sendoso-webhooks-asyncapi.yml.

    description: Record the date-window trap Sendoso names in its own agent skill.
    update:
      x-gotcha: >-
        Campaigns carry start_date and end_date. A send outside that window fails with
        "Touch not found" even though the campaign exists — the 404 is about the window, not
        the id.
