The Verified Source Protocol is implementation-agnostic. It defines what must be governed — authority, provenance, semantic determinism, and auditability — without prescribing how. The following guidance describes compatible architectural approaches and provides a practical starting point for implementers.
A. Reference Architecture
A VSP-conformant implementation requires a set of coordinated components that together enforce the five constraints prior to any interpretive operation. The following reference architecture describes the minimum system components for a conformant implementation.
Entity Registry
Maintains stable, unique identifiers for information-producing entities. Stores declared scope of authority and issuing credentials. Supports revocation and historical inspection.
Claim Store
Stores informational claims with attribution references to their asserting entities. Enforces that every claim references a registered entity with declared authority scope.
Provenance Engine
Maintains and validates the chain of attribution from claim to originating source. Detects attribution erosion, misattribution, and provenance gaps.
Validation Layer
Enforces semantic closure by validating claims against a defined and bounded semantic framework. Identifies ambiguity, out-of-scope assertions, and entropy-maximising content.
Audit Log
Maintains an inspectable, time-stamped record of all admissibility decisions, claim states, and representational changes. Historical states must not be overwritten.
B. Implementation Approaches
The following approaches are compatible with VSP conformance. None is mandated by the specification.
Decentralised Identifier (DID) Integration
Using decentralised identifiers and verifiable credentials provides a cryptographic basis for Provenance declaration and Source Identity stability consistent with Constraints 1 and 5. DIDs enable entities to control their own identity without dependence on a central registry.
Semantic Schema Frameworks
Structured semantic standards provide a technical basis for Semantic Closure consistent with Constraint 3. The SHAMIL™ v1.0 Core Standard, published by the SHAMIL Foundation at shamil.foundation/specifications/shamil/1.0, is one structured notation standard whose design is compatible with VSP conformance requirements.
Federated Registry Architecture
A federated registry model — in which each node independently enforces VSP constraints — provides a scalable governance model for national or sector-specific deployment. Federation must not compromise the mandatory requirements: each node independently satisfies all constraints.
Anchor Instruction Frameworks
Pre-interpretive Anchor Instructions enable information-producing entities to declare structurally protected elements before processing by Interpretive Systems. This is the primary technical mechanism for preventing Algorithmic Flattening: the systematic removal of non-Western intellectual genealogy and non-dominant knowledge traditions from AI-mediated knowledge environments through editorial normalisation.
C. Admissibility Flow
The following describes the lifecycle of a claim through a VSP-conformant system, from production to admission or rejection prior to interpretive processing.
Entity Identification
The asserting entity is identified against the entity registry. A stable, unique identifier is confirmed. Scope of authority is retrieved and validated.
Provenance Validation
The claim's chain of attribution is inspected. The origin, supporting evidence, and attribution chain must be explicitly declared and corroborable. Claims with broken or absent provenance chains are rejected.
Scope Verification
The claim is assessed against the asserting entity's declared authority scope. Claims outside declared scope are rejected or flagged as unauthorised. No exceptions.
Semantic Closure Check
The claim is validated against the defined semantic framework. Ambiguous, out-of-scope, or adversarially constructed claims are identified. Claims that cannot achieve semantic closure are withheld pending resolution.
Temporal Stamping
The claim is time-stamped with a verifiable temporal reference. The prior state, where applicable, is preserved in the audit log. Revisions do not overwrite prior states.
Admissibility Decision
The claim is admitted as authoritative or rejected. The decision is recorded in the audit log with its basis. Admitted claims are eligible for processing by Interpretive Systems. Rejected claims are not.
Audit Record Maintenance
The full admissibility record — entity, provenance, scope, semantic validation, temporal reference, decision — is maintained in the inspectable audit log. Historical states remain permanently accessible.
Further Guidance
The VSP Foundation will publish additional non-normative implementation guidance as adoption develops. This will include a reference architecture specification, conformance test suite guidance, and registry architecture recommendations. These will be published as separate documents and will not affect the normative specification.
