The Specification section uses _amount in the Redeem event, so I'm inclined to not make this change.

Also _amount is used in the Transaction struct in the Rationale section 🤷

Not sure what that has to do with the current change here - if anything, this fixes that.

Also _amount is used in the Transaction struct in the Rationale section 🤷

Again, I'm pretty sure that you're confusing the lines that changed. This PR changes amount to _amount, not vice versa.

#5547 (comment)

thanks for changing this and my bad that this issue got through the check, it was named initially amount but we changed to the _amount just to differentiate it as the private variable..

That's what I get for reviewing in the wee hours of the morning 🤣
