I know, but can you tell me the specific meaning of tapscript (Many previously disabled opcodes are redefined to be OP_SUCCESS opcodes that unconditionally render the entire script valid to simplify soft fork upgrades.)? I don’t understand what OP_SUCCESS specifically redefines? How is it used?

In tapscript when the interpreter encounters one of the OP_SUCCESSx opcodes, it instantly succeeds. In the future this might change, and some opcodes might enforce restrictions - soft fork. But the future is not here yet, so nobody knows what and how exactly would happen. So there was OP_CAT at the very beginning, then it was disabled, and now inside tapscript there's OP_SUCCESS126 instead, which might change (in future tapscript version) to something else (instead of instant success).

Here is the list of the codes redefined as OP_SUCCESSx, the red ones were disabled in usual script:
OP_RESERVED = 0x50, OP_VER = 0x62, OP_CAT = 0x7e, OP_SUBSTR = 0x7f, OP_LEFT = 0x80, OP_RIGHT = 0x81, OP_SIZE = 0x82, OP_INVERT = 0x83, OP_AND = 0x84, OP_OR = 0x85, OP_XOR = 0x86, OP_RESERVED1 = 0x89, OP_RESERVED2 = 0x8a, OP_2MUL = 0x8d, OP_2DIV = 0x8e, OP_MUL = 0x95, OP_DIV = 0x96, OP_MOD = 0x97, OP_LSHIFT = 0x98, OP_RSHIFT = 0x99,
and everything between
OP_CHECKSIGADD = 0xba,and
OP_INVALIDOPCODE = 0xff,

Thank you. Can you tell me a demonstration website with a full transaction script?
