May 1, 2025May 2025 focused on strengthening VV tracking, run orchestration, and documentation to improve reproducibility and accelerate model experimentation for MNCNH and related Vivarium components. Key features delivered include consolidated VV tracking across MNCNH versions 6.1–6.5 and associated run requests, enabling consistent VV handling and automated model runs; expanded support for model versioning with 6.2.1, 6.5, and Model 7 VV/run requests; and enhanced best-practices documentation and VV validation components. Additional accomplishments include scenario-based tests, cause-specific V&V, ferritin screening instructions, and postpartum depression model; plus a note on single-draw annotation and observer pattern notes. Major stability improvements were achieved through CI/build fixes, merge conflict resolution, and observer-related corrections, alongside maintenance and documentation updates to improve clarity and traceability. Overall, the work increases model reproducibility, reduces time-to-run for experiments, and strengthens the governance of VV/V&V across versions, demonstrating strong Python, data modeling, documentation, and CI skills.
