This month focused on strengthening governance and auditable history for signed statements within the ietf-wg-scitt/draft-ietf-scitt-architecture repository. Key deliverable: Auditability Policy Language Update for Signed Statements, refining authorization and data quality checks language by updating the requirement from MUST to SHOULD to enable flexible, interoperable implementations while preserving traceability. This change aligns with Registration Policies to support efficiently auditable histories across deployments. The update was implemented in the draft-ietf-scitt-architecture repository and linked to commit d015ba4e9afb8031e40f1fd30ccd36c22debfc0a.

February 2025 monthly summary for ietf-wg-scitt/draft-ietf-scitt-architecture: Delivered a targeted documentation refinement to enable flexible implementations by updating the architecture documentation to describe consensus protocols rather than prescribing replication and consensus protocol pairings for protecting the Append-only Log and Verifiable Data Structure. This change reduces technology lock-in, clarifies guidance for implementers, and aligns with broader deployment scenarios.

December 2024: Delivered a new use case for signing certificate authorization verification to strengthen software supply chain trust, refined architecture documentation, and clarified roles while maintaining consistency by removing a conflicting use case as recommended by governance. All changes are traceable to specific commits in the ietf-wg-scitt/draft-ietf-scitt-architecture repository.
