Robin Bryce updated the SCITT architecture documentation in the ietf-wg-scitt/draft-ietf-scitt-architecture repository, introducing the concept of a 'Statement Sequence' to clarify how signed statements are tracked within verifiable data structures. Using Markdown and technical writing skills, Robin enhanced the terminology around append-only logs, focusing on improving auditability and integrity verification for auditors and stakeholders. The documentation changes anchored new definitions to the macro concept of append-only logs, ensuring conceptual consistency throughout the architecture. This work addressed compliance and verifiability requirements, providing clear guidance for verifying data integrity and completeness without introducing new bugs or regressions during the update.
