PRODUCT · ATTESTED MIRROR

The model store you can put in front of an auditor.

Frontier weights with cryptographic provenance, witness panel review, and a Merkle log that any independent verifier can validate. Built for organizations that can't ship "trust us" as a security architecture.

the problem

Pulling weights from a public hub is a procurement question your security team can't answer.

Where did those weights come from? What was the training corpus? Have they been modified since publication? When the model behaves unexpectedly in production, can you prove what version was running? On HuggingFace, the answer to all four questions is "we don't know." For most internal experiments that's fine. For ATO, FDA SaMD, IEC 61508, or NERC-CIP, it's a stop-work.

the solution

Every weight signed, every promotion witnessed, every claim verifiable.

Tier-gated promotion

CLOSED → QUARANTINE → HARDENED. Promotion to Hardened requires that we hold the weights, verify their SHA-256 against the publisher's hash, and pass a supply-chain scan mapped to NIST AI RMF / COSAIS — signed by our own key. Demotion is a single revocation signature; cascades are automatic.

Supply-chain scan

Every artifact promoted to Hardened is scanned on our own infrastructure and the findings mapped to NIST AI RMF and COSAIS controls. The scan report is signed and anchored alongside the weight hash, so an auditor can read the control mapping rather than take a badge on faith.

Rekor anchoring

Every promotion, demotion, and cosignature appended to a Merkle log with full inclusion proofs. Cross-mirror gossip propagates checkpoints. Independent verification at any time.

Independent verification

The sf-verify tool ships as a 465-line Python script with no Apex dependencies. Your security team can validate every claim without trusting our infrastructure.

Quantization-aware

INT8 / INT4 / FP8 derivatives chain back to their sealed FP16 base through signed compile manifests. The trust chain doesn't break when the airframe needs a 4-bit quant.

Drift detection

Reverification runs on schedule. Witness rotation, key compromise, and revoked publishers are caught and propagated automatically. Your customers see the demotion the moment it lands.

who it's for

Three procurement constraints we built this for.

Defense primes

JADC2, CDAO, and program offices that need attested AI under DoD SWFT and ATO frameworks. Mirror runs in your VPC; signatures roll up to your audit pipeline.

Regulated medical

Hospital systems, medical device manufacturers, and clinical research organizations bound by FDA SaMD, HIPAA, and the EU AI Act high-risk classification.

Sovereign infrastructure

Grid operators (NERC-CIP), water utilities, financial institutions, and national AI initiatives where the provenance posture is itself a procurement requirement.

pricing

Annual subscription. Per organization, not per user.

Pricing reflects the curation work, not the storage cost. Every customer gets the full catalog, full witness coverage, full audit trail.
