Quick start

Validate one card, look at its result and see what it does not claim.

pipx install claimbound-evidence
curl -LO https://raw.githubusercontent.com/ClaimBound/claimbound-evidence/main/docs/evidence_cards/CLAIMBOUND-NASA-POWER-D103-2026-04-29.json
claimbound validate-card CLAIMBOUND-NASA-POWER-D103-2026-04-29.json
claimbound inspect card CLAIMBOUND-NASA-POWER-D103-2026-04-29.json

validate-card checks the card against the protocol rules: required fields, exact status and level strings, raw_payload_committed set to false, a baseline summary for positive records, a block or drift reason where applicable, and consistent AI-assistance fields. It does not judge whether the claim is true. inspect card prints a short summary; add --keys claim_boundary known_limitations to read specific fields.

Before quoting a card, read three fields: result_status, reproduction_level and claim_boundary. The concepts page explains them.
