ClaimGuard

The receipt for your claims. Verifies a signed GSPC board's Ed25519 site_attestation, payload completeness, and whether natural-language claims are supported by the board.

Measurement, not certification. CSOAI Ltd (UK 16939677).

Why it exists

Session failure mode: mutate a signed result after signing, or claim "16 measured axes" / "jail separation resolved" when the living board says otherwise. ClaimGuard fails those deterministically — including when we make them.

Usage

pip install cryptography
python claimguard.py --self-test
python claimguard.py check --live
python claimguard.py check --live --claim "16 measured axes"

Exit 0 = PASS, 1 = FAIL.
