CD21: Python Calculation and Validation Codebase: An Executable Verification Framework for the Big Flare-Up Theory (V1)

Abstract

Abstract This paper documents CD21, an executable software framework ("V1") that implements equations of the Big Flare-Up Theory (BFUT) as running code rather than static text. The current release executes a 73-row report spanning P16, P17, P18, P19/P19A, P22, P23, P26, P27, and P28; evaluates the Dark Matter Effects (DME) law against 175 SPARC rotation curves and four KiDS-1000 weak-lensing mass bins; evaluates six additional named systems; and exposes the same Result objects through a desktop interface. One bundled SPARC file, UGC01230, is empty, so the software explicitly substitutes the classification published for that named galaxy in BFUT P78 Appendix A and labels the fallback in the source. The automated suite contains 15 pytest test functions and 74 assert statements. This paper records what the current code actually executes, the values it produces, the observational calculations it performs, and the limits of what those executions establish.
