Real native machine code via mmap(PROT_EXEC). No exec(). No strings. Raw x86_64 bytes: mov, add, sub, imul, cmp, je, jne, call, ret, jmp. ack(3,4): 0.12ms JIT vs 1.5ms CPython vs 28ms interpreter fib-rec(20): 0.16ms JIT vs 3.4ms CPython vs 40ms interpreter Added cond support to JIT (cascaded comparisons → conditional jumps). Fixed JIT cache: sentinel value prevents retry on unjittable functions. System V AMD64 ABI: args in rdi/rsi/rdx, callee-saved r12-r15. Tail calls use jmp (true TCO at machine code level). 691 lines of jit.c. 114 functional tests pass. All C tests pass.
