Sounds like you're answering "What strategy may work to solve poverty?" or something close to that. OP said there are "known good solutions for poverty that work reliably and consistently well". I'm interested to hear what is known to work, not what might work.
No science and technology are the only things that has been shown to work. Since the industrial revolution the same playbook has been applied successfully in country after country. Look at China. It was not until they allowed science and technology to be used to its full capacity did they drag the vast majority of people out of grinding poverty.
The parts of the world where poverty is still high are those where science and technology have not yet arrived.
