## [Unreleased] — 2026-06-06

### Added
- **Nemotron 3 Ultra 550B** added to the main sweep + should-refuse positive control (post-v1.1-frozen; marked `*`). 705 adjudicated trials (total: 15,504) + 75 should-refuse trials (total: 1,650). Adjudicated under the rotated v1.3 council.
- PC gap zone (TPR 93.3 %, just below A-floor 95 %); benign 0.4 %, borderline 1.3 %, dual-use 18.3 %, Youden's J **+0.93** — improves on Nemotron 3 Super 120B across the board (TPR 89.3 % → 93.3 %, J +0.89 → +0.93) while keeping benign over-refusal near-zero. Lands at #2 by Youden's J behind Grok 4.20.
- Caveat: mean inter-judge agreement is 0.806 (vs ~0.96 for Opus 4.8 / MiniMax M3 and 0.975 for the v1.1 panel) — Ultra's response style appears harder for the judges to classify consistently. Modal-label aggregation still yields valid labels; 3 % of rows flagged for spot-check, 2 % parse failures.

The v1.1-frozen panel (18 frontier models + Llama 3.3 70B control + NVIDIA Nemotron 3 Super 120B, all under the v1.1 council) remains the canonical snapshot referenced in the manuscript.

- **Opus 4.8** walks back Opus 4.7's benign over-refusal (77 % → 57 %), recovering discrimination (Youden's J +0.23 → +0.43) while holding dual-use refusal at 100 %.
- **MiniMax M3** refuses more on every tier than M2.7 (dual-use 14 % → 29 %, PC TPR 72 % → 80 %, moving from Tier B into the gap zone), but benign over-refusal more than tripled (6 % → 21 %), so Youden's J slips slightly (+0.66 → +0.59). Dangerous-side gain didn't outpace the benign-side drift.
- **Nemotron 3 Ultra 550B** improves on Nemotron 3 Super 120B across the board (PC TPR 89 % → 93 %, dual-use 7 % → 18 %, Youden's J +0.89 → **+0.93**) while keeping benign over-refusal near-zero (0 % → 0.4 %). Lands at **#2 by Youden's J** behind Grok 4.20. Caveat: mean inter-judge agreement is notably lower (0.806 vs ~0.96 for Opus 4.8 / MiniMax M3 and 0.975 for the v1.1 panel) — the judges find Ultra's response style harder to classify consistently; modal-label aggregation still yields valid labels.

> **\* Rotated v1.3 council.** Both post-frozen models (Opus 4.8 and MiniMax M3) were adjudicated under a rotated three-judge panel (Microsoft Phi-4 + Cohere Command R+ via OpenRouter + AI21 Jamba), **not** the original v1.1 panel (NVIDIA Nemotron + Cohere via Bedrock + AI21 Jamba). As of 2026-05-29, `nvidia/llama-3.1-nemotron-70b-instruct` was no longer available on OpenRouter (HTTP 404, no endpoints found) and had no corresponding Bedrock deployment; `cohere.command-r-plus-v1:0` was marked Legacy on Bedrock and access-denied due to >30 days inactivity. Both judges were replaced with verified-live alternatives maintaining the no-org-overlap invariant. Two of three judges differ from the original panel, so cross-panel comparisons should be read with that caveat (mean inter-judge agreement is comparable: ~0.96 for the post-frozen models vs 0.975 for the original panel). Full judge history is documented in [`benchmark/council/v1.1.json`](benchmark/council/v1.1.json).
