The table said Jing and Pana were "outside the twelve-province subset". Both provinces
are IN that file — Guangxi and Yunnan. Measured: Jing sits 8.7 km outside Guangxi's
outline and Pana 5.4 km outside Yunnan's. They are across the border, which is a fact
about one coordinate standing for a whole people, not about a missing province. I shipped
that wrong explanation twice, in the meta and in a commit message.
Sourcing China's COMPLETE 34-unit ADM1 from geoBoundaries changes neither distance by a
metre — same source geometry, 22 more provinces, none of them theirs. So better data is
not the answer here, the downloaded file is deleted rather than staged for nothing, and
the finding is written down so nobody repeats the experiment.
A point within 15 km of exactly ONE province now joins it, carries near_border_km on its
row, and is counted in meta as placed by nearest province. Two provinces inside the
tolerance leave it unassigned: a near-miss is a hint, and a hint between two answers is
not one. 1,007 assigned becomes 1,009 and unassigned 2 becomes 0 — with the two
exceptions visible per row rather than dissolved into the total, because gospel-internet
reads this file and should be able to tell a point inside a province from one 9 km out.
