v0.31 ships the KuzuDB-backed knowledge graph, EU AI Act / GDPR governance exports, and the nova-worm-conformance test suite for object storage compliance.
v0.31 is the largest release since the initial capsule format stabilised. Three major features ship together: the knowledge graph backend, governance compliance exports, and a standalone WORM conformance test suite.
All capsule relationships — asset versions, run lineage, model call chains — are now queryable via a KuzuDB-backed graph. The 13-tab dashboard includes graph visualisation and Cypher query panels. A 10M-edge benchmark confirms the backend handles realistic production-scale capsule histories.
Risk classification and audit profiles are now available for EU AI Act, NIST AI RMF, GDPR, SOC 2, and NIS2. These are evidence exports for compliance workflows — not legal guarantees. Cost reporting and per-run audit trails ship alongside them.
A standalone Python package that verifies object storage backends (S3, MinIO, Ceph, Azure Blob) meet WORM requirements for SEC 17a-4, MiFID II, CFTC 1.31, and FINRA 4370. Ten mandatory test cases covering immutability, retention locks, legal holds, and lifecycle exemptions.
