Methodology
1. Sources
We prioritise official and primary sources and cite them when available.
2. Formulas
We turn rules and data into formulas, showing assumptions and limits when available.
3. Tests
We use automated tests on the calculations; they are not a substitute for professional review.
4. Corrections
Reports are reviewed; confirmed corrections are documented where the system supports it.
Who maintains the product
