What we won’t fabricate

C Mazzoni Bros has 196 permits, but too few carry a value we can stand behind — so we publish for reliable value, never a guess. They still rank by volume; the dollar figure stays honest.

Below our reliability threshold — too few filings carry a value we stand behind

Monthly value isn’t shown: too few of C Mazzoni Bros’s permits carry a reliable valuation, so we publish the count trend only rather than a value line built from gaps.
