import { Tenant, Currency, TenantOperations, SystemClock, UuidV7IdGenerator } from '@superheld/summae-core';

const clock  = new SystemClock();
const tenant = Tenant.inMemory('Demo GmbH', Currency.of('EUR'), clock, new UuidV7IdGenerator(clock));
const ops    = new TenantOperations(tenant);
ops.execute('createFiscalYear', { year: 2026, start: '2026-01-01', end: '2026-12-31' });
const susa = ops.project('trialBalance', { fiscalYear: 2026, throughPeriod: 12 });
