Why architecture matters here

Model supply-chain failures include hidden backdoors, license violations, and untraceable data lineage. Architecture matters because verification + isolation + registry compose the trust chain.

The architecture: every piece explained

The top strip is source and gates. Model source. Provenance. Weights signing. Verify at load.

The middle row is safety. Backdoor scan. Eval before serve. Isolation sandbox + egress. License compliance.

The lower rows are governance. SBOM for models. Registry. Ops — patch + retirement + IR.

End-to-end flow

End-to-end: model downloaded from HF. Provenance attestation verified. Signature checked. Backdoor scan finds no known triggers. Eval on safety + tasks passes. License allowed for use. Registered in internal registry. Deployed in isolated sandbox with egress controls.
