Standard for Cryptographic Data Integrity
and Sovereign Audit
In modern digital and corporate ecosystems, a fundamental evidentiary asymmetry persists. Institutions — banks, insurers, cloud providers, public administrations — dictate truth through proprietary legacy systems, black-box algorithms, and opaque compliance processes. Individuals and small enterprises lack the tools to independently verify, document, and defend the integrity of their own data.
FAS-26 was developed to address this asymmetry. It defines a universal, process-oriented framework that transforms raw data into cryptographically verifiable, modular dossiers. The standard is industry-agnostic, jurisdiction-independent, and operates on the principle of Evidence-as-Code: evidentiary artifacts and commercial truths are treated like immutable source code — versioned, hashed, and independently verifiable.
FAS-26 does not replace existing legal or regulatory frameworks. It provides a technical layer that strengthens the evidentiary value of data within those frameworks.
This standard applies to any process that transforms raw data into verifiable, stakeholder-facing dossiers — regardless of industry, legal jurisdiction, or data format.
FAS-26 is applicable to, but not limited to: forensic compliance audits, regulatory escalations, industrial cost accounting, financial reporting, identity verification, and cross-border documentation transfers.

| Term | Definition |
|---|---|
| Auditor | The natural or legal person executing the FAS-26 process. Assumes responsibility for dossier integrity and signs the Seal in Phase 5. |
| AuditReady | A conformity predicate confirming production through a complete FAS-26 5-Phase Loop with minimum Level 1 Seal. |
| Dossier | The structured output of a complete FAS-26 process: MAD (Profile F) or IAD (Profile I). |
| Evidence-as-Code | The governing paradigm. Evidentiary artifacts treated as immutable, versioned, and hashable data objects. |
| Ingest Artifact | A raw data object entering Phase 1, preserved in its original format without conversion. |
| MAD | Modular Audit Dossier — output of FAS-26/F (forensic evidence with chain-of-custody). |
| IAD | Industrial Audit Dossier — output of FAS-26/I (verified commercial calculations). |
| Seal | The cryptographic closure applied in Phase 5. Three levels defined (Section 5.3). |
| Sovereign Perimeter | The isolated processing environment in which the FAS-26 process executes. |
The FAS-26 standard operates independently of industry and legal system, provided these four axioms are satisfied. A process that violates any axiom cannot claim FAS-26 conformity.
Any process bearing the designation "FAS-26 Compliant" or "AuditReady" shall complete all five phases in sequence. No phase may be omitted.
The moment at which the primary source enters the FAS-26 process. Artifacts preserved in original format, each with an initial SHA-256 Base Hash. Phase concludes with a Completeness Confirmation documenting total number, format, and hashes of all ingested artifacts.
The engineering or forensic analysis phase. The Auditor isolates the discrepancy between target state and actual state. Output must contain at least one quantifiable metric. Analysis conducted without emotional or speculative assessment.
The strategic routing phase. Profile assignment (F or I) determines dossier character. Profile F executes as WEAPONIZE (accountability identification). Profile I executes as VALIDATE (commercial verification).
Construction of the final dossier from Phases 1–3. Must maintain unbroken reference chain from output back to each Ingest Artifact (chain of custody).
Irreversible finalization. Master Hash (SHA-256) computed over all component hashes. After sealing, no component may be modified without breaking the Seal.
| Attribute | FAS-26/F (Forensic) | FAS-26/I (Industrial) |
|---|---|---|
| Domain | Compliance, fraud detection, regulatory escalation, litigation | Industrial controlling, cost accounting, B2B verification |
| Phase 3 Mode | WEAPONIZE — accountability assignment | VALIDATE — commercial accuracy verification |
| Phase 3 Output | Target Matrix (named individuals/institutions) | Stakeholder Matrix (banks, auditors, authorities) |
| Dossier Type | MAD (Modular Audit Dossier) | IAD (Industrial Audit Dossier) |
| Min. Seal Level | Level 1 (Level 2–3 recommended) | Level 1 |
| # | Component | Content | Phase |
|---|---|---|---|
| 1 | Dossier Header | Profile, rationale, case reference, Auditor identity, Seal Level, Master Hash, timestamp | 3 + 5 |
| 2 | Ingest Documentation | Completeness Confirmation: number, format, Base Hash of each artifact | 1 |
| 3 | Audit Report | Quantified target-actual analysis with methodology disclosure | 2 |
| 4 | Integrity Manifest | SHA-256 hash of every component. Master Hash over all. Seal Level proof. | 5 |
Governs transfer of dossier components across language boundaries. Translated documents use Bilingual Mirror format with SHA-256 link between original and translation. Translator qualification and translation type (sworn or technical) must be declared.
Defines the format for sworn declarations (eidesstattliche Versicherung / declaración jurada) within a FAS-26 dossier. Anchors the Auditor's personal accountability to factual statements. Must reference the specific dossier by Master Hash.
| Type | Numbering | Scope |
|---|---|---|
| Patch | V1.0.x | Typographic corrections, clarifications. No normative change. |
| Minor | V1.x | New optional modules, additional normative guidance. Backward compatible. |
| Major | Vx.0 | Changes to axioms, phase definitions, or minimum requirements. |
Each published version is sealed with SHA-256 and deposited at the canonical URI. The publication history ensures no retroactive modification can occur without detection.
