FIOS sits between existing systems and between firms. It replaces nothing. It keeps one shared record of each trade or loan, matches both sides field by field, separates real differences from formatting noise, and keeps every step in a tamper-evident trail.
One view of every trade's life: execution, allocation, affirmation, instruction, settlement. Department views over the same record; breaks predicted before settlement.
Open →Two versions of the same trade, typed any order, any format. Same substance shows green; a real difference shows red with the field named.
Open →Daily state of every open loan compared with the other side. Faults flagged the day they start, not at month-end billing.
Open →Every action in a tamper-evident chain, searchable by date, trade or person, for investigations.
Open →All four screens run on the same engine and the same record. This is a working prototype on generated sample data: no firm's real data is used or needed to explore it.
