The Arets resultat summary card on the bokslut preview step read its
figure from generateIncomeStatement, which excludes entries tagged
source_type='year_end'. Bokslut-flow entries (annual depreciation,
bokslutsdispositioner) carry that tag, so the card showed the
pre-depreciation result while the bokslutsverifikation table below it
(built from the unfiltered trial balance) included depreciation in the
2099 balancing line.
previewYearEndClosing now derives netResult from the closing-lines
totals before the balancing line is appended: it equals, by
construction, the signed amount transferred to 2099 (AB) or 2010 (EF);
positive = credit = vinst, negative = debit = forlust. The posted
verifikat is unchanged: executeYearEndClosing only consumes
preview.closingLines, never netResult.
