EXD.6:4.1 - Fix the receiving question and its criterion
State what the explanation should let this recipient recover or do. Identify the subject criterion and an available explanation that can serve as the incumbent. A mathematical claim needs its correct derivation; a recommendation needs its actual grounds and conditions.
For a structural comparison, use FPF C.2.8: identify the account, its expression and observer, qualified by the selected relations, correctness criterion, preparation, available operations, access, assistance and budget. Choose a qualitative description of recovered and missing relations when it is sufficient. A numeric amount needs its own declared scale and units or denominator.
Distinguish recovering what an account asserts from establishing that assertion’s subject warrant. If warranted subject structure is the selected target, an unsupported relation cannot count as a correctly supplied ground.
