Official CAIN-42 IHVRK (Independent Human Verification Resource Kit): KEYSTONE CI Don't trust CAIN-42. Verify CAIN-42. What the product is said to do: KEYSTONE CI gates every pull request (AI-agent PRs first) with deterministic rules and signs the verdict as an in-toto/DSSE attestation bound to the exact diff and head commit, re-checkable offline. This kit holds 13 claim(s) from https://cainstudio.online/top25-keystone-ci.html, each as the exact request and the value its answer must contain. They were run live on 2026-11-03T22:46:54+00:00 and every answer matched (a run that does not match publishes no kit). Check it yourself (Python 3.8+, standard library only, no CAIN-42 code, no account): python3 verify.py offline: hashes, Ed25519 signature, recorded answers vs. claims python3 verify.py --live also send every request again from YOUR machine and check the answers now Compare the key fingerprint verify.py prints with https://cainstudio.online/evidence-kit-key.json, https://mcpgate.online/evidence-kit-key.json and https://clawx.click/evidence-kit-key.json.
