test/functional/test_framework/wallet.py
68 ↗	(On Diff #30162)	I found that most transactions are 207 bytes in size, but occasionaly there is one that is 206 bytes. I don't know if there are other sizes possible. I have not been able to see any other value in a loop of 100 executions of the tests.

rebase on D10247, use ADDRESS_P2SH_OP_TRUE instead of signing a regular p2pkh, move SCRIPTSIG_OP_TRUE to address.py

use correct size for fee computation, subtract 1 when calling pad_tx

test/functional/test_framework/wallet.py
55 ↗	(On Diff #30318)	If `pad_tx` ALWAYS overpads by 1 byte, then the fix should trivial. If `pad_tx` SOMETIMES overpads by 1 byte, then this will fail occasionally. What is the situation ?

test/functional/test_framework/wallet.py
55 ↗	(On Diff #30318)	For this particular transaction size it overpads always by exactly 1 byte. I need to dive deeper into the issue to find out exactly what is happening for larger sizes (>172 if I remember correctly).
