Could you build this?

Partial A lightweight key-value caching service is simple to write, but implementing strict determinism, formal type safety, and memoization guarantees for custom Jev-class decision models requires specialized systems programming.

What it would actually take: The core would be written in Rust or Go, using embedded key-value storage like sled or LMDB with a fast serialization format (e.g., Cap'n Proto or FlatBuffers). The hard part is ensuring byte-level canonical serialization of decision tree states and cryptographic verification across heterogeneous execution environments. A solo builder needs deep knowledge of systems programming, deterministic hashing, and custom VM/interpreter execution models.
