3-model council (GLM-5.1, Minimax-M2.7, Kimi k2p5) analyzed Intel Arc GPU performance issues and produced patches for llama.cpp: Phase 1 - SYCL Sync: Enable graph execution by default (GGML_SYCL_DISABLE_GRAPH) Phase 2 - SYCL Kernel: Fix VER_GEN12/13 thresholds, tune DMMV_X/MMV_Y Phase 3 - Vulkan Intel: Arc 140T device-ID Xe2 override Includes: - Phased apply script (apply-phase.sh [1|2|3|all]) - Master apply script with --status/--reverse/--dry-run - Per-phase READMEs with testing checklists - Council deliberation logs (gitignored in logs/) Verified: all patches apply/reverse cleanly via git apply. Static verification: VER_GEN arithmetic and DMMV_X divisibility pass.
