Fixes 0031. Every merge it made was provably one account — each split pair shared an account_number — but the PREFIX generalises past that evidence. Citibank Australia and Citibank India are different banks with different accounts and currency, and `citi%` flattens them into one. Older Citi India statements are queued to load, so this would have merged them on arrival. Not Citi-specific: `hsbc%` and `%american express%` carry the identical defect. Currency alone cannot be the discriminator: Wise holds AUD, EUR and USD accounts under one provider, so a blanket "non-AUD is a different bank" rule would shatter it into three. Wise stays unmapped for exactly that reason, now a documented property rather than an accident. The country comes from the name when the name states it and from the currency otherwise, with AUD as home taking no suffix — so nothing renames: the backfill touched 0 rows. 'Citibank' + AUD -> 'Citibank' (unchanged) 'Citibank India' + INR -> 'Citibank India' 'Citibank N.A.' + INR -> 'Citibank India' (currency carries it) 'CITIBANK INDIA' + AUD -> 'Citibank India' (name beats a wrong currency) 'N.A.' is deliberately not read as a country marker: it means "National Association", a US legal form printed on Citibank letterhead worldwide, including India. Reading it as US is precisely the mistake this fixes. The trigger now fires on UPDATE OF bank_name, currency, since the country is partly derived from the currency.
