AVCR Private Holdout Authority

BUYER OR EXTERNAL-LAB CONTROLLED VALIDATION

Private labels stay private. Certificates become independently verifiable.

A buyer or external laboratory can generate hidden episodes and labels, publish only a cryptographic commitment, receive a candidate output file, evaluate offline, and issue an Ed25519-signed certificate.

Reference validation workflow

1. Key generationLaboratory-owned Ed25519 signing key.

2. Holdout commitmentPrivate manifest is hashed; public inputs and commitment are released.

3. Submission bindingCandidate output is bound to public digest and private-manifest commitment.

4. Frozen evaluationMetrics and acceptance gates run inside the authority environment.

5. Signed certificateCertificate digest and signature enable third-party verification.

6. Buyer HIL planDevice contract is translated into integration blockers and test sequence.

Ready.

Claim boundary. The included keys, episodes, oracle labels, PASS result, and buyer profile are synthetic reference fixtures. A credible independent validation requires the buyer or external laboratory to replace the test key, private manifest, labels, seeds, data source, and preferably the evaluator implementation inside its own controlled environment. This package does not prove clinical efficacy, cortical fidelity, real implant integration, electrical safety, cybersecurity certification, regulatory clearance, patent validity, transaction value, or acquisition readiness by itself.
