December 2025 monthly summary focusing on delivering a robust pricing and asset management platform with a focus on business value, reliability, and scalability.

November 2025 (2025-11) — MUSE_2.0 delivered a focused set of business-value features, architectural cleanups, and quality improvements. Key outcomes include completing the MarketID refactor: renaming Market to MarketID across the codebase and removing the MarketID struct, reducing technical debt and clarifying downstream usage. Appraisal and demand analytics were enhanced with timeslice-level outputs and support for zero-capacity candidates, plus scaffolding for unmet demand outputs to enable earlier-stage scenario reporting. The modeling engine gained MILP-based optimization improvements, refined SCC ordering, and an external-edge bias to improve solution quality and runtime, alongside extended dispatch capabilities with flexible capacity assets and a new margin parameter. Documentation and testing were tightened through clearer docstrings, doc-build fixes, inputs/results alignment, and a broad test suite. Finally, governance and stability improvements included better error handling, ability to undo deletions/changes, and updated regeneration/results workflows. Collectively, these efforts deliver clearer models, richer analytics, faster and more robust optimization, and stronger support for stakeholder reporting and decision-making.
