Here is a list of all topics with brief descriptions:

Application orchestration	Application startup, MainWindow, global state and desktop-level coordination
Mathematical primitives	Grid containers and transforms shared by the numerical physics modules
Quantum physics and numerical analysis	Schrodinger, gauge-covariant and Dirac propagators, observables and experiment-specific analyses
Experiment catalog and persistence	Guided presets, stable Help/Analysis routing, persistence documents and release audits
Scientific visualization	Renderers, OpenGL view, plot widgets and display-only post-processing
Desktop theme and GUI support	Qt desktop presentation helpers that do not alter physical state
Regression and validation suite	Numerical, persistence, routing and rendering regression checks enabled in debug builds
