GII is auditable by design: any published record can be challenged. A structured challenge corrects evidence and methodology — it is not a vote on whether a policy should be liked. Identify the five fields below and the challenge receives a tracking ID and one of five dispositions: accepted, partially accepted, rejected with reason, pending evidence, or outside scope. See the governance standard for how challenges are handled and how an accepted one becomes a correction.
Illustrative portal. It validates your submission against the contract and returns the tracking ID it would assign; it stores nothing. GII-US is pre-pilot and publishes no scores.
Same contract as POST /api/v1/challenges.
