v3.0 Whitepaper Draft Release Note

Status

DRAFT / NOT FROZEN. This draft captures the public-documentation work prompted by the 2026 Java bridge upgrades to Runtime, MCP tools, model lifecycle, explanation evidence, and governance. It does not change the frozen v1.0/v2.0 content and does not authorize downstream documentation to call candidate behavior GA.

Topics under review

• Runtime Launcher and /readyz/capability discovery;
• datasource registry, diagnostics, and namespace binding;
• Bundle registration, model validate/refresh, and catalog generations;
• dataset.list_models, dataset.explain_query, Compose, and the split chart export tools;
• authoring workspaces, immutable artifacts, release packages, promotion, rollback, and recovery;
• management authentication, opaque Authorization, audit, explain evidence, and optional AI Providers.

Not frozen yet

Tool error envelopes, complete authorization closure, remote datasources, pre-aggregation, some addons, production-promotion support levels, cross-implementation compatibility, and all public schemas still require owner confirmation. Until then, cite the implementation manual and runtime capabilities rather than this draft as a guarantee.
