Unchecking the wrong bank account and putting the right one on 1930
answered 400 "Flera bankkonton kan inte bokföras på samma konto": the
collision pass counted every stored account as a claim, the picker
hides the ledger dropdown for unchecked rows, and disconnect plus
reconnect re-claims the same cash_accounts rows by IBAN. No route out
(support case 2026-09-09, two 400s on the route in the Vercel logs).
Checked accounts stay hard claims (duplicate and foreign-live = 400).
Unchecked accounts hold their ledger as a soft claim: kept and mirrored
with enabled=false unless a checked account wants it, then they yield
and lose the prefill. Contested rows (this connection's row for a
yielded or moved account, another connection's row for an account
unchecked there) are demoted to manual in one update before the mirror,
so upsertFromPsd2 promotes the holder in place and row ids, transaction
links and the is_primary flag on the 1930 row survive. The same pass
makes two checked accounts swapping ledgers work, which previously
tripped the unique constraint in both upserts and was swallowed.
