WHENWhen implementing monetary calculations in the parsing stage

ACTIONuse Decimal type from beancount.core.number instead of floating-point types

CONSEQUENCEFloating-point arithmetic produces rounding errors that accumulate in financial calculations, leading to incorrect account balances and audit failures

WHENWhen parsing directives from Beancount source files

ACTIONrequire every directive to have a valid date field as primary identifier

CONSEQUENCEDirectives without dates cannot be temporally ordered, causing incorrect balance calculations and non-deterministic transaction sequencing

WHENWhen encoding Beancount source files for parsing
