Integrity in a Regulatory Environment.

Preserving legally referenceable regulatory state.
In the context of UCVreg, "security" is not merely about uptime or password complexity. It is about the preservation of truth in an enforcement regime. Records must remain verifiable for decades, data must survive system sunsets, and historical truth must be immune to mutation. Regulatory enforcement environments do not evaluate intent. They evaluate evidence.

Core Mechanism

Publish-Time Anchoring

When a Digital Product Passport is published, the structured payload is canonicalized, and a deterministic SHA-256 hash is generated. The issuance state becomes immutable, and subsequent operational edits cannot alter it.

Canonicalization: Ensures consistent byte representation.
Hash Generation: SHA-256 hash seals the content.
Immutable State: Operational edits do not affect the sealed record.

This is not document storage. It is cryptographic sealing of structured regulatory data.

This model aligns with regulatory expectations for non-repudiation and traceability. Any subsequent alteration to the record will result in a hash mismatch.

Our integrity model is designed to satisfy traceability, non-repudiation, and audit continuity expectations present in EU regulatory frameworks such as ESPR and EUDR.

Hash Linked

Write Once. Append Only. Deterministic Reconstruction.

Regulatory history must be preserved. Lifecycle events are appended, never rewritten, and never deleted.

WORM Principle

Write Once, Read Many. No retroactive mutation is possible without breaking the cryptographic chain.

Deterministic Reconstruction

Historical state can be rebuilt exactly as it existed at any point in time.

What We Guarantee

Immutability Guarantee

Published artifacts cannot be altered. Once sealed, the content is frozen forever.

Verifiability Guarantee

Integrity can be independently validated via hash recalculation by any third party.

Chain Integrity

Lifecycle events cannot silently modify original declarations. The sequence is unbreakable.

Retention Integrity

Records remain structurally retrievable over long time horizons, independent of ERP changes.

Boundaries of Responsibility

UCVreg guarantees the integrity of the structured regulatory state. We do not guarantee the factual accuracy of input data, physical product authenticity, or operational cybersecurity inside customer ERPs.

Clarification: We secure the integrity boundary. Customers control their operational inputs.

Access Control & Tenant Isolation

Strict RBAC is enforced at the API layer, with separation between Drafter, Approver, and Auditor roles. No implicit permissions exist.

Logical Isolation: Multi-tenant architecture ensures complete separation of data.
Encryption: Separate encryption keys per tenant.
No Visibility: Zero cross-organization data leakage.

Inspections evaluate systems, not conversations. Inspection is a data request, and the system must answer deterministically.

Schema Preservation

Historical context intact with original schema versions.

Completeness Checks

Controlled verification of record completeness.

Architecture, Not Policy.

Security in regulatory systems is not a statement. It is a property of system design.

UCVreg enforces immutability at the structural level. It does not rely on user behavior, best efforts, or internal guidelines to maintain integrity.

Regulatory trust is not asserted.
It is verifiable.
