    tACK 5e0cd25e29541e6c19559fb5c2555e008ed896fa. I noted this a while ago while fixing feature_taproot.py for elements. Verified that the extreme ranges of CScriptNum are correct and the overflow case for `CHECKSIGADD` works as intended. Adding 1 to 2^31 - 1 results in an overflow, but the interpreter puts a `vch` of corresponding to 2^31 on stack. Even though it cannot be converted to CscriptNum(restricted to 4 bytes), it's result can still be compared by OP_EQUAL.
