The Sun Dagger marks the solstices, equinoxes and lunar standstills, and great houses and shrines are aligned to solar and lunar extremes.

## Where it stands

**Most likely** Its tests partly supported it: two pieces of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- The Fajada markings occur at the lunar standstill extremes as well as the solar stations.
- Great-house walls and shrine lines cluster on lunar standstill azimuths beyond chance.

## What would rule it out

- A pre-registered alignment test across all great houses and shrines that finds no excess at lunar azimuths.
