Autonomous AI decisions engage liability — but not through system performance. They become legally attributable only when a competent human authority has documented governance before execution. SOURCE 0 defines this evidentiary threshold as T‑0: the moment where human authorisation is cryptographically sealed by an independent authority. Without a T‑0 seal, an AI act has no author — and under the EU AI Act and the Product Liability Directive 2024, that is a liability without a ceiling.

Trusted Execution Environments seal AI workloads at the silicon level. They do not produce legally opposable evidence. When the operator controls the attestation keys, the Hardware Attestation Report remains endogenous to the system under audit — a structural circularity that no firmware update resolves. SOURCE 0 CERTIFIED closes this gap with an independent Governance Proof Layer: T-0 Capture, SHA-256 hash-chaining, dual-QTSP RFC 3161 timestamping under eIDAS 2, and judicial archiving by a Commissaire de Justice. The result is a Dossier de Réalité Historique directly enforceable across the EU under Brussels I bis — satisfying the ex-ante burden of proof imposed by AI Act Article 99.

Faced with Shadow Runs and systemic frontier model drift, standard downstream observability (SIEM/EDR) fails. The SOURCE 0 doctrine introduces Opposability-as-a-Service (OaaS): an ex-ante cryptographic baseline and judicial escrow designed to protect directors by shifting the burden of proof back to the regulator.

On June 3, 2026, locally-executed agentic AI (Gemma 4 12B) bypassed enterprise cloud controls, creating an unprecedented forensic void.

Offline AI agents operate outside centralized SIEM architectures, destroying the evidentiary chain of custody by design. Under NIS 2 and DORA, corporate directors face a systemic evidentiary trap: sandboxing the agent destroys its utility, while leaving it unconstrained eliminates the traceability of management diligence.

Read the complete architectural blueprint on how the SOURCE 0 Doctrine implements a deterministic T-0 cryptographic capture to secure absolute corporate compliance.

Un chauffeur professionnel condamné pour conduite avec permis périmé, malgré dix-neuf condamnations antérieures que l'employeur ignorait : ce jugement révèle l'impasse structurelle entre l'obligation de contrôle des dirigeants et l'interdiction légale de surveillance continue. SOURCE 0 y répond par un double Dossier de Réalité Historique scellé à T-0.

La dette d'acculturation désigne l'écart entre la vitesse d'adoption de l'IA agentique et la maturité organisationnelle réelle. Ce différentiel produit le Shadow Run — des déploiements hors périmètre de gouvernance, nominalement conformes mais invisibles aux outils de surveillance traditionnels.
