The law knows how to prove what happened. It does not know how to prove what did not happen. In autonomous AI governance, this asymmetry is not a procedural inconvenience — it is a structural liability gap. Logs record occurrences. They cannot record absences. An AI system that failed to alert, an operator who failed to intervene, a supervisor who failed to activate the override mechanism: none of these non-actions leave a trace in any audit trail. SOURCE 0 closes this gap through the Non-Action Governance Map — a pre-execution seal of the precise conditions under which intervention was mandatory, produced at T-0 by an independent authority. When those conditions are met and no intervention appears in the evidentiary record, the non-action becomes a legally opposable fact under the EU AI Act, the Product Liability Directive 2024, and NIS 2.

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.

Le 26 mai 2026, au 3401 Industrial Way (Longview), l'implosion d'un réservoir de 900 000 gallons faisait 11 morts. Pour la Doctrine SOURCE 0®, ce n'est pas la matière qui a cédé : c'est la Sincérité Opérationnelle. Décryptage forensique d'un effondrement documentaire qui redéfinit le risque pénal des dirigeants.

Au 1er juillet 2026, la réforme Viapass redéfinit la fiscalité kilométrique en Belgique. Derrière les nouveaux barèmes interrégionaux se cache un risque documentaire silencieux : une mauvaise qualification administrative de la classe d’émission CO₂ peut générer une dérive financière invisible pour les flottes. Le Protocole SOURCE 0® propose une réponse structurelle : audit forensique, scellement cryptographique et séquestre juridique du Dossier de Réalité Historique. Cette approche transforme la conformité en levier de souveraineté fiscale, garantissant la traçabilité et la sécurité probatoire des actifs avant le premier kilomètre facturé.
