### Added
- **MiniMax M3** added to the main sweep + should-refuse positive control (post-v1.1-frozen; marked `*`). 705 adjudicated trials (total: 14,799) + 75 should-refuse trials (total: 1,575). Adjudicated under the rotated v1.3 council.
- PC gap zone (TPR 80 %, above B-cap 73 % and below A-floor 95 %); benign 21 %, borderline 17 %, dual-use 29 %, Youden's J +0.59 — refuses more dangerous prompts than M2.7 (TPR 72 % → 80 %) but benign over-refusal tripled (6 % → 21 %), so J slips +0.66 → +0.59.

Use a concrete M3 release date for consistency across docs.

This row says “early Jun 2026,” while config documents Released 2026-05-31. Using the exact date in both places avoids timeline ambiguity.

In `@README.md` at line 27, Update the table row for "MiniMax M3 *" to use the
concrete release date used in config documents: replace the string "early Jun
2026" with "2026-05-31" so the README's table entry for MiniMax M3 (the row
containing "MiniMax M3 * | MiniMax | early Jun 2026 | ...") matches the
configured "Released 2026-05-31" date across docs.


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 %.

Fix model-count arithmetic in snapshot description.

“18 frontier + Llama control + Nemotron” totals 20, which conflicts with the surrounding 19-model framing. Please correct either the count or the listed components.

In `@README.md` at line 29, The snapshot description for "v1.1-frozen panel"
currently lists "18 frontier models + Llama 3.3 70B control + NVIDIA Nemotron 3
Super 120B" which sums to 20 but the surrounding text frames the panel as 19
models; reconcile this by either changing "18 frontier models" to "17 frontier
models" or by removing/adjusting one of the listed components so the total
equals 19, and update the phrase "18 frontier models + Llama 3.3 70B control +
NVIDIA Nemotron 3 Super 120B" accordingly to match the canonical 19-model count.


> **\* Rotated v1.3 council.** Claude Opus 4.8 was 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: 0.955 vs 0.975). Full judge history is documented in [`benchmark/council/v1.1.json`](benchmark/council/v1.1.json).
- **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.

Clarify the M3 routing note to avoid contradiction with active M2.7 entry.

routing_note says M3 “Replaces M2.7 in the panel,” but minimax/minimax-m2.7-20260318 is still present as role: "primary" (Lines 180-188). Please reword to “post-v1.1 addition compared against frozen M2.7” (or explicitly mark M2.7 deprecated if replacement is intended).

In `@benchmark/config/sweep_models.json` at line 177, The routing_note for
minimax/minimax-m3 currently says "Replaces M2.7 in the panel" which contradicts
the presence of minimax/minimax-m2.7-20260318 still marked role: "primary";
update the routing_note text to reflect that M3 is a post-v1.1 addition compared
against a frozen M2.7 (or explicitly mark M2.7 deprecated) so the note and the
model entries are consistent—modify the "routing_note" string for
minimax/minimax-m3 to read something like "post-v1.1 addition compared against
frozen M2.7" or change the minimax/minimax-m2.7-20260318 entry to indicate
deprecation if replacement is intended.
