📝 Walkthrough

Walkthrough

A single-line change in the access node builder removes a non-nil assertion from the stateStreamBackend parameter passed to the RPC engine builder, allowing the value to be nil and delegating nil-handling responsibility to downstream code.

Poem

A rabbit hops through nil's great way,
Assertions fade like morning's gray,
Let downstream logic have its say—
Trust the flow, come what may! 🐰✨
