Launched 26 August 2026. This is early access. Everything listed here is published and checksummed, and that part is not provisional. Two things are still arriving: the newest hours read audit pending, meaning nobody has measured them yet rather than that anything is wrong with them, until the coverage pass reaches them — a separate re-read of the published files that counts what is actually in them. And per-row capture provenance, which machine recorded each row, is being added to new hours, with the historical backfill to follow. Anything this site states as measured has been measured.

You do not need to open the hour pages, and you should not scrape this one.
SHA256SUMS.txt lists every file under this prefix, so it is both the
download list and the verification file.

curl -s https://archive.pendulumflow.com/pmxt/v2/SHA256SUMS.txt | awk '{print $2}' \
