During April 2026, this developer enhanced the getprobo/probo repository by implementing a CMMI maturity level field for compliance controls, supporting formal effectiveness measurement aligned with ISO 27001 and HITRUST CSF requirements. The solution was designed to be framework-agnostic and nullable, ensuring flexibility across diverse compliance frameworks. Using Go, TypeScript, and GraphQL, the maturity level field was exposed consistently across all APIs, including GraphQL, MCP, CLI, and n8n, and integrated into the generated Statement of Applicability. This unified approach improved audit readiness and reporting by making maturity data accessible throughout front-end APIs and documentation, supporting future compliance initiatives.
