Reason extraction_buffer_m is null.
Tier: optional
Why this slot matters
An empty buffer field is ambiguous: it could mean no buffer was used or that the radius was simply not recorded. Stating the reason makes the absence deliberate and checkable, so validators and reviewers do not flag a legitimate point extraction as incomplete metadata.
In plain terms
When the circle-radius field above is left empty, this field says why — most often because no circle was drawn at all and the value was taken straight at the address. It turns a silent blank into an explicit, trustworthy statement.
