## Where it stands

**Most likely** Its tests partly supported it: two pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- The groups of crescents and heralding sequences match the Rapanui night names recorded by Thomson in 1886.
- The text following the calendar marks where intercalation falls.

## What would rule it out

- The crescent groups cannot be matched to any lunar month structure.
