Regulators regulate markets. Courts adjudicate facts. Only architecture can produce proof. The DMA designation of cloud gatekeepers does not resolve evidentiary independence.

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.

SOURCE 0 — Evidentiary Sovereignty for Autonomous Systems

SOURCE 0 introduces the first evidentiary architecture designed for autonomous systems operating under endogenous observation. It establishes a structural truth: no system can verify itself without perturbing itself. Instead of denying this limit, SOURCE 0 makes it explicit, measurable, and legally enforceable.

Across the European regulatory landscape — NIS 2, DORA, AI Act, eIDAS 2, and the EU Customs Trust & Check regime — a unified expectation is emerging: proof must be contemporaneous, independent, and externally verifiable.

At the core of SOURCE 0 is the Historical Reality Dossier (HRD): a sealed, pre‑execution evidentiary record, anchored through qualified timestamps and held under judicial custody. It transforms digital events into sovereign, regulator‑grade evidence.

SOURCE 0 is not a compliance framework. It is a doctrine of evidentiary sovereignty. Compliance is no longer declared — it is proven, sealed, and timestamped at T‑0.

The Missing Evidentiary Standard in European Regulation. Modern enterprise architecture has a structural blind spot. While frameworks like AMLR, the AI Act, DORA, and NIS2 demand absolute proof of compliance, traditional operational systems only produce vulnerable, post-hoc logs.

Discover how the Governance Proof Layer (GPL) instantiated by SOURCE 0 introduces a dedicated, hardware-enforced infrastructure layer—decoupling processing from forensic proof to secure human-in-the-loop decisions strictly prior to execution.
