    API Evangelist enrichment pass 2026-08-24. Captures descriptive and contact metadata absent
    from Biconomy's published contract, plus the runtime semantics recorded in
    conventions/biconomy-conventions.yml and errors/biconomy-problem-types.yml. Applied as an
    OpenAPI Overlay so the published spec at
    https://docs.biconomy.io/supertransaction-api/openapi.yaml stays byte-faithful in openapi/.

    description: >-
      Record that the API accepts no idempotency key, that execution is irreversible once
      settled, and that quotes expire in roughly 30 seconds.
    update:
      x-idempotency: none
      x-reversibility: >-
        No reversal operation exists after /v1/execute settles. Reversal machinery is
        pre-commitment only: cleanUps, upperBoundTimestamp, simulate, and Smart Session
        revocation. See conventions/biconomy-conventions.yml.

    description: Warn that 500 is not blind-retriable on write operations absent an idempotency key.
    update:
      x-retry-guidance: >-
        Safe to retry composition calls. Do not blind-retry /v1/execute — no idempotency key
        exists, so a retry after a request that actually landed can double-execute. Poll
        https://network.biconomy.io/v1/explorer/{supertxHash} first.
