Subject: [PATCH 1/4] feat(minimaxm3-h200-agentic-mtp): add EAGLE3 AgentX
 recipe with golden-AL synthetic acceptance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add minimaxm3-fp8-h200-vllm-agentic-mtp, the spec-decoding=mtp variant of the
MiniMax-M3 MXFP8 H200 agentic-coding recipe: Inferact/MiniMax-M3-EAGLE3 draft
head, 3 speculative tokens, FLASH_ATTN drafter, and synthetic acceptance pinned
to the committed golden AL 2.83 (minimaxm3_eagle3.yaml, thinking_on, K=3).
EVAL_ONLY keeps real target verification. Serve shape, Mooncake offload and
search-space arms mirror the non-MTP sibling, trimmed at the top concurrencies.

中文：新增 minimaxm3-fp8-h200-vllm-agentic-mtp，即 MiniMax-M3 MXFP8 H200 智能体
编码配方的投机解码（spec-decoding=mtp）变体：Inferact/MiniMax-M3-EAGLE3 草稿头、
3 个投机 token、drafter 固定为 FLASH_ATTN，合成接受长度固定为黄金 AL 2.83
（minimaxm3_eagle3.yaml，thinking_on，K=3）。EVAL_ONLY 保留真实目标验证。服务参数、
Mooncake KV 卸载与搜索空间沿用非 MTP 版本，仅在高并发端裁剪。

+# decoding — the spec-decoding=mtp variant of agentic/minimaxm3_fp8_h200.sh.
+# Everything outside the speculative block mirrors the non-MTP agentic sibling

Subject: [PATCH 3/4] fix(minimaxm3-h200-agentic-mtp): drop
 gpu-memory-utilization to 0.90 to fit the EAGLE3 draft
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The H100 twin of this recipe died mid-warmup with torch.OutOfMemoryError on all
8 ranks (run 30515793863) because it inherited the non-MTP agentic sibling's
gpu-memory-utilization, which leaves no headroom for the draft head and its KV.
Apply the same correction here pre-emptively: 0.90, matching
fixed_seq_len/minimaxm3_fp8_h200_mtp.sh, the proven MTP setting on this SKU.

中文：本配方的 H100 版本在预热阶段因 8 个 rank 全部 OOM 而失败（run 30515793863），
原因是沿用了非 MTP 版本的 gpu-memory-utilization，未给草稿头及其 KV 预留显存。此处
预先做同样的修正：改为 0.90，与本 SKU 上已验证的 MTP 配置
fixed_seq_len/minimaxm3_fp8_h200_mtp.sh 保持一致。

Replace the dense integer sampling inherited from the non-MTP agentic siblings
with the AgentX MTP grid: GPU-resident [1,4,8,12,16], offload [4,8,12,16].
Single-step sampling cannot separate configs by more than noise on the agentic
corpus, and past conc 16 these SKUs are in the post-cliff thrashing regime.

GPU 常驻 [1,4,8,12,16]，KV 卸载 [4,8,12,16]。相邻并发间隔至少为 2，且一律止于 16 ——
逐 1 采样在智能体语料上无法区分出超过噪声的差异，并发超过 16 后这些 SKU 已进入
显存瓶颈后的抖动区间。
