  title: Factorial Amend Contract
  summary: Find an existing contract version and update it, otherwise create a new one.
  description: >-
    A find-then-act flow for contracts. The workflow lists contract versions,
    branches on whether any exist, and then either updates the most recent
    contract version with the supplied changes or creates a brand new contract
    version when none exists. This is the building block for promotion, salary
    change, and contract renewal integrations. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
