Scorecard sandbox

An illustrative, in-browser calculator that runs the @gii/core reference implementation of the GII-US six-dimension scorecard on hypothetical inputs — including the withhold rule.

This calculator runs the @gii/core reference implementation — the same code that ships in this repository, conformant to methodology v1.1.1 — directly in your browser. Adjust the inputs and every dimension of the scorecard recomputes live: magnitude and direction from the indicators, confidence from its five components, concentration from the distribution, coverage from the preregistered outcome map, and the all-important withhold decision.

This is not a score. The tool computes GII dimensions from the hypothetical inputs you supply and asserts nothing about any real government decision. GII-US is pre-pilot: no production scores exist for any administration, party, branch, court, agency, law, regulation, or policy. The seed is the fictional example from whitepaper
Illustrative calculator. This runs the @gii/core reference implementation in your browser on the inputs below. It publishes no scores and asserts none — GII-US is pre-pilot. The seed is the fictional Hypothetical National Reporting Rule from whitepaper; at the forecast stage its observed headline is correctly withheld.

  • maturity is "forecast" — an observed headline requires an observed maturity state
  • weighted coverage 50% is below the provisional 70% threshold
  • no direct stakeholder outcome is observed
  • implementation or exposure cannot be verified
  • only outputs or forecasts are available
  • counterfactual is absent
  • no causal statement — an observed-impact record must state its estimand before data analysis
  • no measurement clock — the record does not say when the outcome became observable

How to read it#

The six dimensions are always published side by side. GII-M is direction-neutral impact magnitude — flip an indicator’s orientation and the magnitude does not move; only GII-D does. Confidence is never multiplied into magnitude, so a weakly identified large event stays large but carries a low GII-C. When any condition fails, the observed headline is withheld and the reasons are listed — withholding is a successful control, not a failure. See the methodology and data dictionary for the full definitions.
