bug: order summary: incorrect "You receive" amount

[f321x]

Describe the bug
The "Your receive" satoshi amount when buying bitcoin as maker shown in the "Order" tab of the ongoing trade during the chat period is incorrect. I noticed in multiple trades that the amount shown is much lower than the actual trade amount.

To Reproduce
Steps to reproduce the behavior:

1. Make offer to buy bitcoin for Euro in an amount range on Temple of Sats
2. Wait for it to get taken
3. Once in the chat, open the "Order" tab
4. See too low "You receive" amount.

Expected behavior
"You receive" should show the amount for which the user submitted the lightning payout invoice in the previous step.

Screenshots
(should be >1m sat here at the current exchange rate):

• OS: Android, Browser, independent of system
• Version: 0.8.3

That's strange, I get the correct amount.

@FedericoLuque your screenshot is of a newly created offer before locking the bond right? Mine is after the offer has been taken, during the chat stage

@f321x I can see that your onion address doesn't match mine. Are you accessing the official Robosats website?

I believe that is my frontend instance: http://ngdk7ocdzmz5kzsysa3om6du7ycj2evxp2f2olfkyq37htx3gllwp2yd.onion/

But it should not make a difference, as it is the same running the same code as the "official" one...

@f321x was this a range amount order?
Could you ping me privately with order ID so that we have more info to replicate the issue?

Thanks!

@FedericoLuque i am using the Temple of Sats instance. Did you create a range offer or a fixed amount offer? I was creating a range offer when encountering this bug.

@TempleOfSats yes this was a range offer. DMing you the offer id.

[TempleOfSats]

Just few notes that might be helpful to replicate

this was a

• BUY range order 500 - 1000 euros (1% premium. 3% bond)
• Taken at 800 euros
• Backend calculated Escrow Size: 1060856 Sats / Payout Size: 1057679 Sats

I have identified the root cause.

@TempleOfSats and @f321x are correct—the issue is a calculation mismatch for taken range orders.

In frontend/src/components/OrderDetails/index.tsx, the satsSummary logic incorrectly forces the use of max_amount for the exchange rate calculation whenever has_range is true, ignoring the fact that the order was already taken at a lower specific amount (e.g. 800 vs 1000)
I have a fix ready that aligns the logic with TakeButton.tsx (prioritizing order.amount when available),opening a PR

I think it's solved here: #2329
