Could you build this?

Partial While a simple naive rules engine is easily promptable, building a formal, high-performance vectorized rules engine from first principles requires deep algorithmic knowledge of AST parsing, Boolean logic compilation, and vectorized execution.

What it would actually take: A true vectorized rules engine requires designing a domain-specific language (DSL) parser, translating rules into an abstract syntax tree (AST), and compiling them into bitwise or vectorized SIMD instructions (often using NumPy, Apache Arrow, or native Rust/C++ arrays). It requires deep knowledge of formal grammar parsers, computational logic optimization (such as Rete-like optimizations or decision diagrams), and memory layout alignment for high-throughput rule evaluation.
