Swapped mig_native_adapter.v + sdram_arbiter_n.v into the full N=2 system (neural_director_packed.v + 2x packed_slot.v), replacing the SDR SDRAM placeholder used since EXP-0057. Verified against the real Vivado-generated ddr3_model.sv end-to-end: 8/8 positions bit-exact against golden model, 0 errors, real JEDEC command traffic observed. This is the first fully real V3 system-level correctness result: real packed DSP cores + real weight-reuse scheduling + real N-way arbitration + real DDR3 timing, all verified together.
