SX-to-OCaml transpiler (transpiler.sx) generates sx_ref.ml (~90KB, ~135
mutually recursive functions) from the spec evaluator. Foundation tests
all pass: parser, primitives, env operations, type system.
Key design decisions:
- Env variant added to value type for CEK state dict storage
- Continuation carries optional data dict for captured frames
- Dynamic var tracking distinguishes OCaml fn calls from SX value dispatch
- Single let rec...and block for forward references between all defines
- Unused ref pre-declarations eliminated via let-bound name detection
