The proposed Evidence Platform is a federated digital infrastructure designed to preserve the integrity, accessibility, and accountability of criminal evidence within the justice system. At its core, the platform establishes a canonical “Origin of Truth” repository—an immutable evidentiary ledger maintained within isolated Kubernetes clusters operated collaboratively by law-enforcement agencies and prosecutors. All evidentiary artifacts, including digital files, metadata, and chain-of-custody records, are ingested through controlled pipelines and stored as cryptographically verifiable objects that cannot be altered once recorded. This architecture ensures that the authoritative evidentiary record remains tamper-resistant and independently auditable while preserving the evidentiary chain of custody.
The platform replaces traditional disclosure models—where prosecutors selectively distribute evidence—with a direct access discovery model. Defense counsel receives secure, read-only access to the same canonical evidence corpus used by prosecutors. Courts function as an observability authority, monitoring access logs, discovery compliance, and chain-of-custody events rather than acting as custodians of the evidence itself. Oversight entities at jurisdictional, state, and federal levels consume telemetry streams from the system, enabling systemic monitoring of disclosure practices and evidence integrity without interfering with operational case workflows.
A Drupal-based application layer operates as the Evidence Platform interface, providing structured metadata management, indexing, workflow orchestration, and discovery tools. The separation of application services from the underlying evidence store allows institutions to interact with the evidentiary corpus through controlled APIs while preserving strict isolation of the immutable storage layer. Each participating institution—prosecutors, defense organizations, courts, and oversight bodies—may operate independent compute environments or Kubernetes clusters, enabling them to run analytical workloads, artificial-intelligence agents, or investigative tools locally while referencing the shared evidence repository. This design preserves institutional data sovereignty while maintaining a unified evidentiary record.
To support emerging agent-driven legal workflows, the platform can incorporate interoperable agent standards such as Open Standard for Software Agents (OSSA), which defines machine-readable manifests governing agent identity, capabilities, and authorization. This enables AI-based legal analysis tools—such as evidence classification systems, transcription engines, or discovery-completeness auditors—to operate across institutional boundaries while remaining subject to cryptographically verifiable identity and policy enforcement.
Agent discovery and interoperability may further be supported by protocols such as the Decentralized Universal Agent Discovery Protocol (DUADP), which enables decentralized discovery of autonomous services across domains, creating a federated ecosystem where organizations can publish and locate analytical agents and services.
Complementing this ecosystem, specialized distribution environments—such as an AI agent marketplace—allow institutions to deploy modular agents that automate operational tasks, integrate external systems, or perform domain-specific analysis on evidence metadata.
Governance of these agents can be coordinated through a contract-plane model, where explicit task contracts define permissions, resource limits, and expected outcomes for autonomous systems interacting with evidence-related workflows.
Surrounding the core platform is an ecosystem of Peripheral Projects—external systems that interact with sanitized or derivative datasets rather than the evidence store itself. These projects may include public transparency portals, research environments, AI training platforms, compliance monitoring dashboards, and legal workflow tools. By interacting only with derived metadata, audit telemetry, or anonymized datasets, these systems enable transparency, research, and innovation while ensuring that the canonical evidence repository remains isolated from potential attack surfaces.
Collectively, the Evidence Platform transforms evidence management from a fragmented document-exchange process into a distributed evidentiary infrastructure. Immutable storage guarantees evidentiary integrity, direct discovery access strengthens procedural fairness, and continuous observability enables institutional accountability. By combining cloud-native infrastructure, federated governance, and interoperable agent technologies, the platform establishes a secure and transparent foundation for evidence handling in modern digital justice systems.
