I pause in Genius at the moment the preview looks safe, because the market can keep moving while I am still deciding.
That is the awkward part of a fast action panel. I can open a token, get a route preview, see minimum received, check the pool depth, and feel like the trade has been measured. But nothing has happened yet. The preview is only useful if it is still alive when I confirm.
After the flow already works, Genius still has to make that aging impossible to miss. Did the quote refresh after I changed size. Did the liquidity move while I was reading the risk note. Did the minimum received belong to the current route, or to the route that existed when the panel first loaded.
The visible consequence lands at signature time. I think I am approving a checked trade, but I may be signing an old snapshot with fresh money.
That is not the same as normal slippage. It is stale permission.
If Genius makes the path from research to execution this short, the preview needs to expire loudly before confidence turns into a click.
