 † North-Mini-Code-1.0 is a *reasoning* model, run think-OFF for board parity. ARC-Challenge is reasoning-gated: 60.2 think-OFF to ~95 think-ON (+35), which deflates its q_avg. See the [report](reports/north-mini-code.md).
 
+² Re-banked 2026-07-15 under the pinned harness (rig ec00ff0, llama-server b9653); the re-bank moved HumanEval by one passing problem (92.7 → 93.3) and nothing else beyond 0.05.
+³ unsloth compressed-tensors NVFP4 (23.4GB, 303 modules kept high-precision, lm_head dequanted), served via vLLM 0.21.0 on the native cutlass sm_120 FP4 path, measured 2026-07-15 under the same pin. Protocol and per-suite deltas: [report addendum](reports/qwen3-6-27b-nvfp4.md).
+⁴ NVFP4-GGUF (s-batman MTP GGUF, 14.6GB, flat quant), llama.cpp b9365 `BLACKWELL_NATIVE_FP4`, June numbers, pre-pin: [NVFP4 vs Q6_K](reports/nvfp4-vs-q6-qwen3-6-27b.md). Rows ³ and ⁴ share a format name and nothing else; the 0.9 q_avg spread between them is recipe coverage (which modules stay high-precision), not the FP4 format.
