upg100-plugin ran the per-country fetch (304a4c120): 162 queries against the
geoBoundaries endpoint, values recorded verbatim, 0 failures, one spot-check
re-verified live. 130 of 162 countries carry a duty; only 32 are duty-free.
ATTRIBUTION now says the world-adm0 duties are DISCHARGEABLE and points at the
single authority for them -- their PROVENANCE.json -- rather than copying the
table, because one table in two places drifts. Their words.
★ THE DUTIES ARE RECORDED AS CLASSES, NOT AS ONE THING. They separated the 7
explicit ShareAlike countries because share-alike is a stronger duty than
attribution, which is right; by the same reasoning the class holds 65, because
Open Data Commons ODbL 1.0 also requires a derivative database to be offered
under ODbL. 58 ODbL + 7 CC-SA. This repository already acted on that reading:
Natural Earth's 1:10m roads were deliberately not shipped over an ODbL
obligation. Whether "licensed alike" binds a giveaway is a legal question, not
a measurement, and it is recorded as open rather than resolved here.
The CCK line is gone. It read as an outstanding gap; CCK is absent from
world-adm0 entirely, so that 404 was a fetch for a country that never shipped.
