USING THE FILES
legend.csv defines the columns, units, formats and blank-value meanings.
CSV is UTF-8 with headers. Import identifiers, ZIP codes and phones as text. Blank differs from zero or false.
LICENSES.txt contains source attribution and applicable notices.

LIMITATIONS
- Active registration is not current operating authority, insurance coverage or available capacity.
- Cargo and hazmat flags are registrant reports, not equipment or legal authorization verification.
- Power units and drivers reflect separately dated filings and can be stale.
- No website or third-party place enrichment is delivered; shared business email only follows the captured normalization rule.
- Business registration names and addresses can identify sole proprietors; individual-name flags are heuristic.
