The Python API and the HTTP server now open the device with dispatch on ETH cores, 1 command queue and a 12x10 compute grid by default (the p150 target). Worker dispatch stays only as an explicit opt-in (11x10 on a p150). Card numbers re-measured in this configuration and independently verified; outputs unchanged. tt-model.yaml and SERVING.md are unchanged; they still describe the container image.
Optimized build (2026-10-03): model call 3.49 ms, device 3.36 ms
code/ updated to the independently verified optimized build (12x10 compute grid). README Demo & Performances, GPU_COMPARISON.md update, OPT_REPORT/OPT_BASELINE, VERIFICATION_2026-10-03.md and patches/tt-metal-eth-dispatch.patch. tt-model.yaml and SERVING.md are unchanged; they still describe the container image.
