The original architecture choice and price almost gave me a brain aneurysm, but the "build it with AI" solution is also under-considered.

This looks like a perfect candidate for existing, high quality, high performance, production grade solutions such quamina (independent successor to aws/event-ruler, and ancestor to quamina-rs).
