A euro trip read in dollars books a bill entered in dollars at the rate of the day, from the euro's quote: 12,345.67 USD at 1.1398 is 10,831.44 EUR. The Costs screen and the settlement then turned those euros back into dollars with the dollar's own quote, 1 / 0.87732. Frankfurter rounds the two quotes separately, so they are not exact inverses, and the bill read $12,346.05 the moment it was saved, a $250.00 one $250.01. The error grows with the amount, which is why the large rows showed it first. Paying back what settle-up offered for such a bill left the trip open with the debt flipped the other way. Both sides now convert trip money to the display currency with the trip currency's own quote, the one every entry rate is frozen from. On the server, settlement() fetches that quote for the REST route and for the MCP get_settlement_summary tool, which now makes the same call, and a legacy transfer without a currency reads back through the same factor. On the client, useExchangeRates takes the trip currency as an anchor and converts through its cached quote, falling back to the display currency's while it is missing, so it works offline from cache and needs no change to the settlement response. The final budget builds each row from the unrounded trip amount, because a euro cent is worth more than a dollar cent and 10,831.44 EUR came back as 12,345.68; the balances and settle-up still net whole trip cents. A same-day bill in the display currency now reads exactly as typed on the row, the payer chip, the day header, the totals, Outstanding and the final budget, on both shells and on the shared trip page, and paying the amount settle-up offers leaves both balances at zero. When the rate really moved, the row keeps the value the totals count, with what was entered and the euros it was booked at underneath, "$801.76 -> 685,26 EUR". One helper builds that line for the desktop list, the phone list, payments, the final budget breakdown and the shared page; it prints nothing for an amount of 0 or a bill that reads as typed. The expense editors share one module for their preview. The split summary puts the share the row lends or borrows next to the entered one, "$400.88 -> $390.53 each", and an expense saved without a currency still opens in the trip currency. Both CSV exports add the amount in the trip currency when it differs from the display currency. Kept from before: the desktop totals recompute when rates arrive, a booking's linked cost is labelled in the trip currency, a legacy transfer is read in the display currency, the shared page reads the frozen rate in whole cents, a booking import keeps the currency it was quoted in at a rate frozen before the write (REST and plugin RPC), and the MCP trip summary, the budget-overview prompt and the per-person summary add every row up in trip cents at its frozen rate. The packing-list prompt reads the trip title directly instead of building the whole summary, which could wait on a rates fetch.
