Primary-source check against bas.se (BAS 2026 v2): the official kontoplan
has no account 2012; the enskild firma equity block is 2010, 2011, 2013,
2017, 2018, 2019. 2012 'Avräkning för skatter och avgifter' is a program
convention (Visma, Bokio, Björn Lundén), not standard BAS, and a
non-standard account in BAS_REFERENCE leaks via the backfill into charts,
SIE export and SRU filing.
- remove 2012 from class-2-equity-liabilities.ts, with a tombstone comment
- migration retargets 'Preliminär F-skatt (EF)' lines 2012 -> 2013
(system row plus any clones still carrying the seeded shape)
- pin 2012's absence in bas-ef-equity-accounts.test.ts (2113 precedent)
- correct the swedish-year-end-closing references that motivated #1388,
regenerate atom seed migration
Companies whose charts already got 2012 backfilled keep it: existing
history stays valid; only future template use books 2013.
Closes#1409

Phase 2a quarantined four defects rather than guessing at Swedish accounting.
Each is now resolved against a domain source. KNOWN_BROKEN is empty.
Löneutbetalning could never post. It debited 2710 @0.3 + 2920 @0.12 + 7010 @1.0
against a single 1.0 credit, totalling 1.42x the amount, so the balance trigger
would reject every entry built from it. Rebuilt per the swedish-payroll skill:
Debit 7010 gross, Credit 2710 tax, Credit 1930 net. The 2920 semesterlöneskuld
line is gone because vacation accrual is its own verifikat (7290/2920), and a
legal_note now says the 30% split is schablon and must be adjusted to the actual
skatteavdrag.
Periodiseringsfond avsättning/återföring referenced account 2113. Per
swedish-year-end-closing the year-tagged block is 2120-2129 (2126 = tax year
2026), so 2113 was the fund for tax year 2013: long since reversed and absent
from BAS 2026. Both now use 2110 Periodiseringsfonder, which does not rot
annually, with a legal_note pointing at the year-tagged accounts for a company
that tracks funds per year.
Preliminär F-skatt (EF) turned out to be RIGHT, and the reference was wrong.
Account 2012 "Avräkning för skatter och avgifter" was simply missing from
lib/bookkeeping/bas-data (the file jumps 2011 -> 2013), while the
swedish-year-end-closing skill uses it in two places as an enskild firma equity
sub-account. That is not cosmetic: account-backfill.ts only seeds accounts
present in BAS_REFERENCE, so any entry touching 2012 failed with
AccountsNotInChartError. Added it with the equity SRU code its siblings share,
and a description separating it from 1630, which carries a confusingly similar
name on the asset side.
The port test now distinguishes deliberate divergence from accidental drift:
a pack not listed in INTENTIONAL_DIVERGENCES must still match the seeded JSONB
exactly, and a listed pack must actually differ, so neither an unnoticed edit
nor a stale entry can survive.
