## Where it stands

**Still possible** Its tests haven't settled it: one piece of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- Associations with X-ray sources; periodic activity tied to orbits.

## What would rule it out

- No X-ray counterparts in nearby localised sources at the luminosities such binaries reach.

## Evidence 1 for · none against
