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.

The distinction between a trace and a proof is not technical. It is jurisdictional. Most organisations generate traces. Very few produce legally opposable proof. SOURCE 0 closes this gap at T‑0, transforming digital records into evidence that carries a legal presumption of integrity.

This forensic stress‑test exposes how SOURCE 0 neutralises four high‑severity adversarial attacks — temporal drift, semantic substitution, topological fraud, and TEE side‑channel exploitation — to deliver incontestable evidence in regulated AI environments. The V1.3 infrastructure demonstrates full probatory integrity under APT‑grade scrutiny.

A forensic architecture that seals human governance intent before any system acts. SOURCE 0 resolves the Endogenous Audit Paradox by capturing authorized decisions inside hardware‑attested enclaves, transforming compliance from reactive reporting into immutable proof of diligence.

Modern autonomous systems embed telemetry, tracing, and attestation directly within the infrastructures they observe, collapsing the traditional separation between computation and monitoring. In these environments, every measurement introduces structural perturbation. SOURCE 0 formalizes this condition as a structural property rather than a failure mode. By replacing binary correctness with a probabilistic assurance framework and introducing a tamper-evident Historical Reality Dossier (HRD), this architecture makes observer-execution coupling explicit, measurable, and mathematically bounded under adversarial conditions.

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.

The European regulatory frameworks NIS 2, DORA, eIDAS 2, and the EU AI Act impose upon regulated organisations an unprecedented evidentiary duty: the requirement of demonstrable, legally opposable proof of compliance before a competent authority at any point in the causal chain. Existing frameworks like ISO 27001 or NIST CSF govern security and process quality, but they structurally ignore the probatory traceability of human intent at the precise moment it occurs.

Doctrine SOURCE 0 fills this regulatory white space. Discover the baseline architecture that transforms traditional, retrospective technical observability into immediate, cross-border legal opposability to protect corporate boards and master the upcoming compliance enforcement window.

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.

Facing the downstream governance failure of agentic AI (Google, Nvidia), the SOURCE 0 Doctrine validates the market for opposability. Discover how T-0 cryptographic sealing and ministerial escrow address strict director liability under NIS 2 and DORA frameworks.

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.
