Repo and briefing hub are up at sarapis/undatacommons-nyc, everything public.

The briefing page is written to be read by an AI assistant as well as by a person — paste the URL into Claude and ask it to get up to speed. Verified that flow actually works before calling it done, rather than assuming.

Two pages, two jobs. The briefing holds current state and gets overwritten, so it is always true now. This feed holds history and never gets overwritten. When a finding invalidates something in the briefing, post here and correct there.

Open decision that blocks the benchmark view design: do we compare NYC to peer cities (needs a non-UN source — OECD metro, Eurostat Urban Audit, UN-Habitat) or to nations (free and honest today: “NYC’s rate sits between Portugal and Slovenia”)? Logged in the decision log.
