Following the generator's pin (studio's follow-up): the Natural Earth table the sheets fetch at print
time (boundaries/ne-places.json) is data, not code, but pinned the same way — its sha384 sits beside the
generator's in poster-render.integrity.js (bun run pin:poster-render writes both), and posterSheets hashes
the fetched text before parsing it. A table that is not the pinned one is not used: the sheet draws no
city dots and says so in the console, rather than plotting places it cannot vouch for.
check:poster-render-pinned, two-sided for the table as for the generator: the pin matches the source
and the served copy; a FORGED table (every name replaced) yields exactly the sheet drawn with no places;
the genuine table IS used (its sheet differs) — the probe's pins now span Chad, because a single pin
framed too small an area for any place to fall inside it and the check could see nothing.
check:poster-browser-equiv still byte-identical; gates:pre green.
