Data Provenance Record (DPR) — heterodata.org (the hub)

Site: heterodata.org
Brand: Heterodata — an Arcanum Research project
App: Heterodata front-door / links index (static HTML, no data)
Container: heterodata-web (Caddy 2.8.4-alpine, internal port 80, no host ports)
Intended route: heterodata.org → heterodata-web:80

1. What this is

heterodata.org is the hub of Heterodata — the public front door that every other Heterodata site links back to (via the shared footer chrome "Heterodata — an Arcanum Research project", whose anchor points here). It is a single static index.html served by Caddy: a curated, self-describing index of the live tools and hosted projects the project produces. It ships no data — it is purely a links portal.

It frames Heterodata as a project that builds open, reproducible, fully-offline economic-data tools (data hubs, replication archives, interactive explorers), built with the Anu / Arthur agentic frameworks. "Heterodata" leads; "Arcanum Research" is the umbrella project named in the footer tagline.

2. The linked sites (every card → URL)

Sixteen sites, ordered Hub-first then alphabetical by title. Subdomains move to the target consolidation state: gerhard.heterodata.org (was pubfin.org), leontief.heterodata.org (was leontief.io), vlad.heterodata.org (was leonid.heterodata.org, was ussr.heterodata.org), and shaikh.heterodata.org (was mdata.fyi).

Card title	Link target
DuBois	https://race.heterodata.org
Erwin	https://defense.heterodata.org
Foodberg	https://foodberg.org
FreeNIC	https://freenic.org
Gerhard	https://publicfinance.heterodata.org
Gordon	https://pricestability.heterodata.org
HMDA Explore	https://hmdaexplore.com
JJ Muni (affiliated — external owner)	https://jjmuni.com
Leontief	https://inputoutput.heterodata.org
Lewis	https://trade.heterodata.org
Methodex	https://methodex.fyi
Mordecai	https://agriculture.heterodata.org
Myrdal	https://population.heterodata.org
Nick Anderson	https://www.nickanderson.us
Rachel	https://climate.heterodata.org
Shaikh Data	https://shaikh.heterodata.org
Vlad (Roadmap)	https://ussr.heterodata.org
Volcker	https://volcker.org

All 16 link targets are present and correctly spelled. freenic.org is a DRAFT slice; Vlad is on a roadmap; JJ Muni is an affiliated site with an external owner — all three are present here as required.

3. Routes (hub + its subdomains)

heterodata.org → heterodata-web:80 (this static index)
gerhard.heterodata.org → Gerhard public-finance site (was pubfin.org)
leontief.heterodata.org → Leontief input-output explorer (was leontief.io)
vlad.heterodata.org → Vlad Imperial-Russian and Soviet official-statistics site (renamed from leonid.heterodata.org 2026-07-30, which was ussr.heterodata.org; both old hostnames 301 here)
shaikh.heterodata.org → Shaikh Anu-Viz data hub (was mdata.fyi)
lewis.heterodata.org → Lewis international-economics platform
gordon.heterodata.org → Gordon employment-and-inflation explorer (renamed from starcruiser.heterodata.org 2026-07-30; the old hostname 301s here)

4. Carson Web Standard (D1–D7)

D1 real content: links index with no data. Card descriptions are real and accurate (each describes the actual target project); scanned for lorem/placeholder/TODO/coming-soon/example filler — none present.
D2 completeness: page returns 200; all 11 card link targets verified correct and correctly spelled, plus per-card subpage link rows (blueprint vocabulary) matching the detailed ecosystem dropdown.
D3 offline: fully self-contained — single HTML file plus the vendored Arcanum Site Kit (CSS/JS served from /_shared/), no external CDN, no web fonts (system-ui font stack). No runtime network dependency.
D4 Heterodata chrome: as the canonical identity, the footer carries the shared line "Heterodata — an Arcanum Research project" and links both the hub and the architect, matching the chrome the sibling sites carry (those sites link this word back here).
D5 UX: clear "Heterodata" identity (mark + headline + lede), intuitive responsive card grid (auto-fill, minmax(290px,1fr)), light/dark via the kit theme toggle (follows system, then remembers), accessible (semantic header/section/footer, single h1 then h2/h3 heading order, descriptive link text — card title + URL, not "click here", accent/focus-visible states, sufficient contrast in both themes via the --ark-on-accent token).
D6 ops: served by Caddy on internal :80; / → 200; no host ports (NPM owns :80/:443 upstream, TLS terminates there, Caddy runs auto_https off); restart: unless-stopped; joined to homelab_default.
D7: this document.

5. Ops

Files: Caddyfile, docker-compose.yml, site/index.html, site/provenance.html.
Run: docker compose up -d in ~/sites/heterodata (container heterodata-web, network homelab_default).
Caddy: :80 { root * /srv; encode zstd gzip; file_server }, auto_https off, admin off, JSON access log to stdout.
Health: curl -fsS http://<heterodata-web-ip>/ → 200 with the index HTML.
Route (configure separately in NPM): heterodata.org → heterodata-web:80.
