This diagram shows the call execution flow: starting with sudo_set_network_immunity_period, passing through validation
(signature, nonce, mortality, fee payment), then pre-dispatch checks where it may fail with errors like NetworkDoesNotExist, followed by dispatch and modifies storage: SubtensorModule.NetworkImmunityPeriod, and finally post-dispatch where ExtrinsicSuccess is emitted and fees are settled.
