## Where it stands

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

## What it predicts

- The stone matches a known Olmec source.
- Tool marks show prehispanic tools (obsidian, abrasives), not steel.
- Patina and mineral deposits run continuously into the incised lines.

## What would rule it out

- Microscopy finds metal-tool traces or fresh, unweathered surfaces inside the incisions.
