the readme example named the envelope too

A comment in the first authorize example said the grant would be cr.exec.v1 unless the version was pinned. That stops being true on 18 September, and the readme is the first thing anyone reads.

It says the server's default now, which is what an SDK that sends no version field actually gets, and points at pinning as the way to control it.
