The component suite runs without a DOM renderer, so it proves what a page
paints and never what a button does. That is the right shape for this work,
because the property that matters most is a control being absent — but it
leaves the other half unproven: a form that renders is not a form that
submits, and a write that reaches somebody else's record is exactly the thing
worth watching happen.
The journey stands down while the invitation form has no level control, since
minting a WRITE grant behind the UI's back would prove a path no person can
walk. It names the control it is waiting for, so a run that skips while the
control exists reads as a bug here rather than an absence upstream.
