# SKU measure — unsloth-ud-iq3-s **Not headline.** Headline remains official Q4_K_M on Spark. **Not runner-identical to post-fix Q4.** Engine/host family match only. IQ3 ran on older `run_smoke.py` (md5 `c1a587c8…`) without sanitize / any_of_tools. Do not brand “same-harness vs Q4 40/40” until IQ3 re-runs on the fixed runner. | Field | Value | |-------|-------| | Host | DGX Spark (gb10) | | SKU | Unsloth `Laguna-S-2.1-UD-IQ3_S.gguf` | | sha256 | `8a9ab3f8b3ff1723441cd251e873b295a7ef086d78dbae7515e5e27c8382b002` | | bytes | 48428911520 (~45.1 Gi) | | Engine | poolside llama.cpp laguna `04b2b72` | | Serve | `:8000` briefly (Q4 stopped) · ctx 8192 · alias `local-laguna-iq3s` | | agent_smoke | **38/40 · 95% · 71s** (2026-07-28 20:10 local) | | fails | `repair_04`, `long_06` — same IDs as prior Q4 harness bugs; older runner | | ship gate | ≥ official−2 → **met** on runner that ran | | Q4 restored | yes, alias `local-laguna` on `:8000` after measure | Phone/tablet: **full Laguna non-fit** on iPhone/Android.
