Limitations and assumptions

The cited APR rule distinguishes transaction types and applicable tolerances. This checker accepts a tolerance supplied by the caller; a true result does not determine which rule applies or certify a disclosure.^[2]

A tolerance in percentage points differs from a percentage change and depends on the applicable transaction rules. Apply the exact scope and assumptions explained above.

All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
