fetches all ext-review issues and writes their
parsed contents into

curator_status="new". Until this script runs, your
submission lives only as the GitHub issue.extension_labels.csv to set
curator_status to accepted.pl/<id> labels, build_pl_taxonomy.py
promotes accepted labels into

promoted into ext_claim.csv (they aren't PL
claims) but are surfaced on this page's "Prior labels"
table so anyone landing here sees them next to the auto-detected
category.In short: submitting opens an issue (provenance), and a small ingestion pipeline turns issues into rows the site renders. The loop is currently manual (the curator script must be run by a maintainer); GitHub Actions could automate it on each new issue.
