Answer stability round 1: each US place's draw is seeded by its GEOID, so a changed source moves only the places near the cut; item 78 leaves the plan and the multi-county fetch is filed

2026-10-11, Lilleman auf Larv, through `todo.md` item 78. Goals 2 and 14: ten streets a
place crowded 500 Stockholm customers onto ten streets, and US places of 25,000 or more
left out every town and village. `geo-us.py` draws among the places owning a ZCTA, since
a place owning none can carry no postal code, with Efraimidis and Spirakis's weighted
sampling from a fixed seed, so a rerun on the same sources draws the same places. The
draw keeps about 950 of the 1,584 places of 25,000 or more, and its smallest place holds
210 people. On 2026-10-11 the embed grew from 1.3 MB to 5.2 MB, and the first draw of
`en_US.address` took 75 ms against 19 ms before, within goal 13. `--place-share`,
`--street-share` and `--min-streets` on the import scripts build another set. Valid while
the first reach of a country stays unnoticed beside a test run.
