  [One-Way vs. Two-Way Door Decisions](https://toddschiller.com/artifacts/one-way-door/)

  Test how well Jev, TypeSafe's decision model, tells one-way
  (irreversible) door decisions from two-way (reversible) ones. Explore
  the cached examples, or bring your own OpenRouter key to run any
  decision live in the browser.

  [Recipe Grid](https://toddschiller.com/artifacts/recipe-grid/)

  Turn a free-form recipe into the Cooking for Engineers table format,
  where ingredients are rows and each operation is a cell that spans
  the rows it combines. Worked examples render from fixed data;
  "convert your own recipe" parses your text with Chrome's on-device
  Prompt API (Gemini Nano), so nothing leaves the browser.

  [Bluebikes broken-station detector](https://toddschiller.com/artifacts/bluebikes-broken/)

  Load a month of Bluebikes trip records and flag stations that
  probably had a broken dock by spotting hours where no bikes were
  returned when several normally would have been. Bayesian combination
  of a prior on dock failures with a Poisson model of expected returns,
  rendered as a map, a top-suspects ranking, and a per-station date by
  hour heatmap. All processing happens in the browser.

  [BEA Input-Output Matrix Explorer](https://toddschiller.com/artifacts/bea-io/)

  Manipulate the U.S. industry direct-requirements matrix:
  see its structure, raise it to powers, simulate a final-demand
  shock through the Leontief inverse, and diff it year over year.
  71 industries, 1997–2023.

  [Belief Phylogenetics](https://toddschiller.com/artifacts/belief-phylogenetics/)

  Cluster public-facing thinkers by the "genome" of beliefs they
  publicly profess. Toggle between the wellness / podcast circuit,
  the AI debate, and climate & energy commentators; UPGMA on
  Hamming distance over a hand-curated trait set, with editorial
  overlays for traits that travel together and individuals who
  recombine them.
