Run it
Curated reference runs you can inspect — and reproduce.
INTERACTIVE
Live, in-browser simulation is a deliberately later phase, decoupled from everything on the critical path. This page is a working preview: a gallery of precomputed reference runs you can inspect now, and the exact command to reproduce each one yourself.
Scenario gallery
Each run below ships as static dispatch.csv, prices.csv and summary.toml, rendered by the engine’s offline viewer (viewer/index.html). Every panel carries a provenance header — engine git hash, data-pack SHA-256, scenario hash — so what you see is exactly what the CLI produced.
The curated static run files and the embedded viewer are wired at launch. On this scaffold the cards above link to the scenarios they describe; the run payloads live in the engine repo and its investigation tags.
Run the real CLI today
You do not have to wait for the browser tool. The engine is public and the command is one line:
grid-cli run scenarios/gb-2024-reference.toml --out runs/2024-referenceSee Getting started to build the CLI, and Reproducibility & data for the data packs.
What comes later
- Phase 1 — precomputed response-surface sliders: move a knob, watch headline numbers interpolate live from a precomputed grid. No live solve; the UI states plainly when a value is interpolated versus a real chronological run.
- Phase 2 — the pure-Rust adequacy core compiled to WebAssembly, gated behind a wasm-vs-native digest regression pin in CI before it goes public. The LP dispatch stays native. Deliberately decoupled from everything else, so it never becomes a dependency on anyone’s timeline.
