Documentation
Methodology and sources
Every calculator documents its own methodology: what each check computes, the clause it came from, the assumptions applied, and where the validated scope stops.
Each pack documents its own basis.
What each check computes, which clause it came from, what the engine assumes on your behalf, and where the validated scope stops.
