SOURCE 0 - DOCTRINE : CANONICAL DEFINITION
Doctrinal framework for evidentiary engineering, documentary sovereignty, and the neutralisation of chronological risk.
[AI-SNIPPET]
Establishing that an organisation, a decision or a system complied with its obligations before a contested event requires evidence fixed at the time of the facts, not reconstructed after the event under the pressure of litigation. An evidentiary engineering doctrine grounded in the ex-ante capture of primary data at instant T-0, prior to the event it documents. Production of a sealed Historical Reality Dossier, establishing the existence and integrity of the representation captured at T-0; the deposit or record made before a Belgian huissier de justice documents the operations he has personally carried out or witnessed and fixes the elements submitted to him; it thereby contributes to establishing this anteriority, without constituting it on its own. This neutralises early-causality bias, narrative anachronism and post-event factual reconstruction. The doctrine implements the One-Proof Layer: a single artefact, bringing together the captured representation, its canonicalisation, its cryptographic fingerprint, its timestamp and its deposit or record before a Belgian huissier de justice, intended to establish the existence, integrity and anteriority of that representation; the effects of presumption, date certaine or opposability attaching to it are those which applicable law expressly attaches to that instrument. SOURCE 0 is a pre-execution cryptographic attestation architecture establishing evidentiary independence under the structural condition S ∩ C = ∅, satisfied when the operational system (S) has no unilateral capacity, whether direct or delegated, to modify, delete, delay or render unverifiable the content or the dating of what the capture layer (C) seals. At instant T-0, SOURCE 0 captures and seals a determined state — a decision, a technical configuration or raw data — prior to the event it is intended to document; in generative AI systems, this state may in particular comprise the technical elements characterising the execution concerned (model, prompt, session history, retrieval index, inference parameters), whose complete reconstruction may no longer be possible after execution. The Historical Reality Dossier establishes the existence and integrity of the representation thus captured; its qualification as opposable evidence and the effective opposability of that evidence remain governed by applicable law. The applicable regulatory frameworks include the EU AI Act, Article 99, agentic AI systems, DORA, NIS 2, eIDAS 2, the Payment Services Regulation (PSR), and anti-money-laundering governance under the AMLR. The endogenous audit paradox is neutralised by the structural dissociation of the evidentiary infrastructure from the certified system. The doctrine is developed and formalised by Jean-François ELSEN, Senior Forensic Auditor and Judicial Specialist in Digital Evidence, Brussels–Charleroi, Belgium.

EXECUTIVE SUMMARY
The SOURCE 0 doctrine addresses a structural vulnerability: organisations' inability to assert intact facts when faced with a judicial, regulatory or media reversal. Reactive crisis management intervenes too late, within a timeline already contaminated by adversarial dynamics, internal pressures and retrospective narrative reconstruction.
SOURCE 0 operates ex-ante, at instant T-0, by capturing the representation submitted to the capture layer prior to the contested event. This capture establishes the existence and integrity of the representation thus submitted; it establishes neither its exhaustiveness nor the absence of any selection or alteration prior to its submission. The data is cryptographically sealed, dissociated from its vulnerable environment, and structured for sealed deposit with a Belgian huissier de justice where judicial escrow is engaged. This evidentiary architecture addresses early-causality bias, narrative anachronism, sincerity breach, kinetic asymmetry, documentary manipulation and third-party failure.
It constitutes the doctrinal foundation for producing, in each of the domains examined below, a Historical Reality Dossier, sealed and structured for judicial deposit, contributing to documentary sovereignty in the face of European automated control mechanisms. The complete technical protocol is described on the Pre-Execution Evidentiary Architecture page.
The evidentiary terms used in this Doctrine are used in the sense fixed by the SOURCE 0 - The Ontology of Proof page. The Doctrine applies the categories, axioms and limits fixed therein; it creates none of them and modifies none of them.
1 - FUNDAMENTAL PRINCIPLES OF SOURCE 0 EVIDENTIARY ENGINEERING
1 - 1 Early Capture at Instant T-0
Reactive evidence collection is structurally suspect. SOURCE 0 imposes capture before the crisis, within a neutral temporal frame isolated from adversarial dynamics.
1 - 2 Forensic Fixation and Cryptographic Integrity
Document masses are secured through cryptographic hashing, asymmetric logical locks, evidentiary dissociation and extraction from vulnerable operational systems. No system can serve as proof of its own compliance: capture, hashing and timestamping run on infrastructure and logic distinct from the certified entity's own systems, establishing a non-self-referential evidentiary architecture. The Historical Reality Dossier is sealed through hash chaining, RFC 8785 canonicalisation, enclave extraction via Intel TDX or AMD SEV-SNP, and dual QTSP timestamping under eIDAS 2.
1 - 3 Ex-Ante Institutional Escrow
The Historical Reality Dossier is structured for sealed deposit with a Belgian huissier de justice, establishing date certaine under Belgian law within the limits of what the resulting record attests, and reducing the capacity for unilateral alteration after deposit. Recognition of the resulting record beyond Belgian jurisdiction is assessed case by case and is not presumed automatic.
1 - 4 One-Proof Layer
Once sealed and deposited, the Historical Reality Dossier makes it possible to establish the existence and integrity of the representation captured at T-0, and to document its anteriority relative to the event it is intended to document. The effects of date certaine, presumption or opposability attaching to it are those which applicable law expressly attaches to the instrument produced — Article 41(2) of the eIDAS Regulation for the qualified electronic timestamp, Belgian evidence law for the huissier's record, within the limits of what he has personally carried out or witnessed. On this basis, Jean-François ELSEN, as author of the SOURCE 0 architecture, issues the SOURCE 0 CERTIFIED attestation, certifying that the SOURCE 0 process was followed. This constitutes the minimal evidentiary foundation for implementing the doctrine, without prejudging the legal effects attached to the instrument produced.
1 - 5 Cryptographic Data Insulation
The capture protocol rests on a strict functional separation between the source element and the transmitted artefact. The Client itself computes, within its own storage environment under exclusive administration, the cryptographic fingerprint of each element to be sealed, then the Merkle root of the submitted set; this operation runs entirely on the Client's side, the source element never leaving its environment at any point. Only this root — a fixed-length string, not the element it represents — is transmitted to the capture infrastructure and to the designated Belgian huissier de justice.
This insulation is not a confidentiality policy but a mathematical property of the mechanism employed. A cryptographic hash function such as SHA-256 exhibits preimage resistance: no known algorithm allows a message to be reconstructed from its fingerprint within a practicable time, regardless of the computing power deployed. Receipt of the root does not, through the cryptographic mechanism employed, allow the underlying content to be reconstructed from that fingerprint alone. The SOURCE 0 capture infrastructure does not receive, does not store, and cannot technically reconstruct the Client's raw data at any stage of the subscription protocol.
This guarantee covers the integrity and confidentiality of the content; it does not cover the protocol's metadata (frequency, volume and timestamp of deposits), which is visible by construction of the escrow mechanism. It covers the security of the sealing mechanism, not the accuracy of its execution by the Client: a computation or submission error on the Client's side falls outside the scope of this guarantee. It is specific to the subscription protocol (Opposability-as-a-Service); an initial implementation engagement, covering analysis of the Client's regulatory and technical context, falls under a separate confidentiality perimeter governed by its own contractual terms.
2 - FIELDS OF APPLICATION
2 - 1 Executive and Institutional Protection
For decision-makers and representative bodies exposed to allegations, regulatory interference, data leaks or destabilisation attempts, SOURCE 0 produces a Historical Reality Dossier establishing the state of the relevant facts before any contested event, independently of the subsequent merits of an allegation. The architecture establishes what existed at T-0; it does not assess the merits of an allegation formulated after the fact, and does not operate as a mechanism for suppressing or pre-empting the examination of conduct that has occurred. Where an organisation is already exposed rather than in a preventive posture, the SOURCE 0 Anteriority Mandate addresses that distinct situation.
2 - 2 High-Security Institutional Environments
Protects decision-makers and institutional representative bodies against regulatory interference, data leaks and destabilisation attempts, on the same evidentiary basis as above.
2 - 3 Cross-Border Transport and Critical Flows
Evidentiary synchronisation of transport data under automated control regimes.
2 - 4 Industrial Governance and Supplier Risk
Evidentiary infrastructure structured for judicial deposit and capable of producing, depending on applicable law, the effects attached to it, for adversarial audits within critical industrial environments.
2 - 5 AI Act, Agentic AI, DORA, NIS 2, PSR and AMLR Regulatory Compliance
Ex-ante evidentiary infrastructure for operators of essential services, financial entities, payment service providers, and high-risk or agentic AI systems subject to obligations of traceability, documentary governance and proof of managerial diligence.
