When to use this example
Use this example when you want a complete agreement with minimal branching, or when you need a straightforward starting point for a genuinely linear workflow. For a broader lifecycle with more states, event types, and branching behavior, use Complex Agreement.What to notice before the canonical agreement JSON
Before reading the JSON, notice:- participant address variables marked with
subtype: "participant" - rendered
contentthat uses the same variables - a short set of lifecycle states
- inputs that correspond to signature and acceptance events
- transitions that move the agreement forward with minimal branching
