Replica documentation

What Happens Next? COVID-19 Futures

Local route /interactive-explanation/covid-19/ keeps the original article structure, footnotes, playable epidemic simulations, and long-horizon sandbox while moving provenance to docs and the shared footer and removing translation, share, creator, and supporter shell UI from the public route.

Source snapshot

Vendor baseline came from the published ncase/covid-19 site tree. The local copy keeps the article shell, splash banner, iframe-based simulation modules, footnotes, and sandbox layout while removing translation sidebars, static share prompts, creator bylines, and the supporter-heavy closing block from the public surface.

  • Live original verified against https://ncase.me/covid-19/ on 2026-03-10.
  • The public route now exposes exactly one original-page link through the shared footer.
  • The vendored words/ exports remain in the tree, but their public text was cleaned to match the footer-only policy.

Asset and source map

  • covid-19/index.html keeps the article shell, splash iframe, embedded sim stages, footnotes, and metadata.
  • covid-19/js/blerp.js now only handles footnote placement and internal anchor behavior.
  • covid-19/sim/ preserves the original control surface, SEIR model, stage presets, long-term scenarios, and sandbox runtime.
  • covid-19/words/, covid-19/banners/, covid-19/pics/, and covid-19/sharing/ remain vendored so the article still resolves all inline assets locally.

Known deviations

  • The translation sidebar, translation-guide comments, and static social-share UI were removed from the public route.
  • The opening byline and closing creator, repo, and Patreon-heavy footer were replaced by the shared footer-only reference policy.
  • The article content still keeps scientific and subject-matter links, but in-body upstream original-page promotion was removed from the public shell and cleaned from the extra words exports.

Reproduction notes

  • Vendor the published site tree first, then patch the public shell and helper JS without rewriting the simulation modules.
  • Keep the original relative folder layout; the article iframes and simulation scripts expect the upstream structure.
  • Run both node interactive-explanation/tools/check-public-surface.mjs and node interactive-explanation/tools/smoke-bundle.mjs after touching the article shell or any sim/js/ module.
