One storage write to flip the false to true later, and pause becomes owner-only backdoor. But there was a SSTORE in an admin

Since "0xdeadcode" evokes low-level programming, EVM (Ethereum Virtual Machine) internals, security exploits, and perhaps a bit of rebellious cypherpunk energy, I'll write two versions: EVM (Ethereum Virtual Machine) internals

Then I traced the JUMPDEST that should be unreachable — but a storage collision could reanimate it.
