# Bonsai ternary spike on fv-ml1 GPU 3 (Prime via brokkr): at the 275 W cap, PQ2_0 is 1.93x Q4_K_XL at N=1 but only 1.06x at N=8 (PTQ1_0 1.24x), recovering to ~1.37x at N=16.

`[2026-09-28]` **Bonsai ternary spike on fv-ml1 GPU 3 (Prime via brokkr): at the 275 W cap, PQ2_0 is 1.93x Q4_K_XL at N=1 but only 1.06x at N=8 (PTQ1_0 1.24x), recovering to ~1.37x at N=16.** Positive control passed on tg128 (+1.1%). nvidia-smi's sw_power_cap flag never fires on this card, so "at cap" is judged from board draw. Follow-up (brokkr): moving PQ2_0 onto MMQ from batch 6, like Q4_K (mmvq.cu, `ne11 <= 5`), lifts N=8 to 1.21x, so the dip was partly a kernel threshold. The residual gap is not power. Runs are in `fv-ml1:/tank/spikes/bonsai-2026-09-28/runs{,-mmvq5}/` and on the Booth. The build image was removed; `Dockerfile.build` recreates it. **Acquired for keeps (Prime, 1540):** GGUF PQ2_0/PTQ1_0/mmproj-Q8_0 + the fork source pin in `/tank/aimodels/llm/prism-ml_Ternary-Bonsai-2-27B-gguf/` (runtime/), the MLX 2-bit pack in `/tank/aimodels/mlx/`, 34/34 hash-verified. Weights single copy (no snapshots, /tank not in restic); the fork pin also at `/mnt/smithy/runtime-pins/prism-llama.cpp-87268f77/` (brokkr).
