## Boundary

No caption establishes real location or mining permission.

## Complete source

Fictional two captions: version1 says “This rock came from here”; version2 says “The supplied drawing does not name a quarry.” Neither names an actual place.

## Invitation

Choose a keep/change/open reason for a display reader.

## Next try

Add a reviewed public source date if one is actually available; otherwise keep location open.

## Ordinary possible response

I prefer the bounded second caption because it does not invent a local quarry.
