What part of the Architecture Repository holds specifications to which architectures must conform?

The Standards Information Base serves as a central repository for technical and architectural standards, listing approved specifications, product standards, and strategic directions that enterprise architectures must follow. This ensures consistency and interoperability across the enterprise.

The Enterprise Continuum provides a structure for classifying architecture and solution artifacts, not for holding conformance specifications.

The Governance Log records architectural governance activities and decisions, not the actual standards for conformance.

The Architecture Landscape provides a view of current architectures across the enterprise, not a repository for conformance specifications.

The Reference Library contains architectural reference materials, but the Standards Information Base is specifically dedicated to holding conformance specifications.
