Ledger.SignedAmount column

Direct match 97%

How the model read it

The authoritative register requires a Decimal Ledger.SignedAmount in reporting-sign convention. Current gold observes the exact Decimal column. The audit confirms structure and formatting, but not source currency conversion logic or detailed sign semantics.

Workbook evidence

Cited current gold

Open questions

Is SignedAmount already converted into a single reporting currency, and what conversion-rate/date rules are intended when CurrencyCode is added?

Is the workbook's positive-revenue/negative-expense sign convention the required production convention?
