about

nx_rv64_ctier_gate.nx -- the TIERED engine runs REAL compressed rv64imac code. Loads knowledge/hw/realc_c.bin (gcc -march=rv64imac, 59 compressed instrs; UART==QEMU 010937272a proven by the compressed real-C suite), runs it on tier_run_c (halfword-indexed, JIT-hot-loop-capable) with UART capture, and confirms UART == 01 09 37 27 2a. Also confirms fk_run_c (interpreter) agrees. Proves the PRODUCTION tiered path RUNS compressed binaries. expect_exit: 0
