Open source
The code is in the open.
Marsovius is released under the Apache License, version 2.0. The full source — kernel, pipelines, workflows, agents, twin, surfaces, platform — is published on GitHub. Inspection requires no registration. Forking requires no permission. Production deployment requires no contract.
The licence is the same one used by Kubernetes, Apache Kafka, and TensorFlow. It is permissive, well-understood by institutional procurement, and does not impose any reciprocity that would prevent an internal fork.
The monorepo
The modules
kernel/ontology
The type system that defines what a "patient", "order", "asset" or "branch" is — and what the institution agrees to.
kernel/lineage
Attribution graph. Each leaf field knows the row, the source, the transformation, and the operator who signed off.
kernel/policy
Row, column, and action-level policy. Sovereignty rules expressed as code, reviewed as code, deployed as code.
kernel/predict
In-kernel forecasting. Bound to the ontology, traceable, confidence-published, signed.
pipelines/*
The ingestion layer. WASM-extensible transformations. Native connectors for the systems Europe actually runs on.
workflows/*
A workflow is a versioned, signed, replayable rule. Temporal-compatible runtime. Each branch reviewable in court.
agents/*
Capability-scoped agents. Bounded by the ontology. Tools typed. Prompts reviewed. Memory bounded by retention policy.
twin/*
The digital twin engine. Bidirectional sync, scenario simulation, what-if branches.
surfaces/*
Operator-facing applications. Composed from the ontology. What you see is what the auditor will read tomorrow.

What inspection guarantees
A regulator may audit any algorithm that governs a decision in your environment. An internal security team may verify the absence of telemetry. A research office may verify the absence of hidden third-party dependencies. A customer of any size may fork the entire system and run it on their own hardware.
The publication of the source is the only credible mechanism by which these guarantees can be made.

Where to begin
The repository lives at github.com/marsovius. Each component has its own subdirectory with a README, an architectural overview, and instructions for local development against a sample ontology.
