## Where it stands

**Disputed** One piece of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- A misaligned planetesimal belt at hundreds of au and a companion orbit that can excite it.

## What would rule it out

- A population estimate showing the mechanism is too rare to appear in the Kepler field.

## Evidence 1 for · 1 against
