View calls on chainCall Workflow
This diagram shows the call execution flow: starting with kill_pure, passing through validation
(signature, nonce, mortality, fee payment), then pre-dispatch checks, followed by dispatch which emits events: PureKilled and modifies storage: Proxies, and finally post-dispatch where ExtrinsicSuccess is emitted and fees are settled.
