## Where it stands

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

## What it predicts

- Any deep hole on the east end of the island fills to tide level.
- Water chemistry in the pit matches local groundwater and seawater mixing, not a single channel.

## What would rule it out

- A cut channel with worked walls is exposed between the cove and the pit.
