Could you build this?
No Writing a zero-dependency, 120KB vector search engine in C with custom SIMD intrinsics requires deep low-level systems programming and hardware-level performance engineering.
What it would actually take: The project requires C99/C11, direct AVX2/NEON vector assembly or compiler intrinsics, and custom data structure implementations (like HNSW or flat index scanning with dot-product/cosine math). The primary hurdle is managing low-level memory layout, cache alignment, and instruction pipeline optimization without runtime bloat. A developer needs deep expertise in systems architecture, CPU cache hierarchies, and vector instruction sets.
