Sep 1, 2025September 2025 performance summary for macrosynergy/macrosynergy: Delivered core enhancements to PnL analytics and visualization, improved robustness, and reduced technical debt. Key features delivered: 1) Centralized PnL handling via NaivePnL (refactor of create_results_dataframe) enabling consistent performance metric generation and paving the way for dynamic correlation metrics; 2) Added return_fig support for plotting across NaivePnL visuals to optionally return the Matplotlib figures for flexible workflows. Major bugs fixed: 3) PnL parameters validation to prevent runtime errors when configuration is not loaded. 4) Code quality cleanup: formatting, tests, and docstring improvements. Overall impact: more reliable metrics generation, flexible visualizations, improved maintainability, and a foundation for future metrics/dashboards. Technologies/skills demonstrated: Python, dataframes, plotting (Matplotlib), validation logic, test and docs hygiene, commit-level traceability.
