 For **MI355X → Pro / Pro Official → FP4 → Multi-Nodes**, the panel generates a **1P1D deployment**: one prefill node and one decode node, each running an independent worker. Select **Router**, **Prefill**, or **Decode** to copy its command. Start the [UMBP tier](#3-8-unified-cache-external-linker-umbp) on the prefill node, then both workers, then the router. Send client requests to the router on port `8000`.
 
-The MI355X multi-node strategies follow the [InferenceX AgentX submission](https://github.com/SemiAnalysisAI/InferenceX/pull/3664): **Low-Latency**, **Balanced**, and **High-Throughput** use fixed concurrency presets of **16**, **48**, and **256**, respectively. **Pro** uses EAGLE/MTP; **Pro Official (0813)** uses DSpark, matching the InferenceX checkpoint. Both enable UMBP on prefill by default. The Playground inherits the selected worker, including its speculative decoder and cache settings.

-The Deployment and Playground Docker outputs retain this `v0.5.21` base image for the MI355X Pro and Pro Official FP4 multi-node recipes. `--network host` replaces the single-node `-p` mapping because the two roles run on different hosts.
+Use this image for the **MI355X Pro / Pro Official FP4 multi-node** workers and router, including the additional concurrency points below. The Deployment and Playground Docker outputs select it for all three PD roles. It supports the documented `SGLANG_DSV4_DENSE_MXSCALE` and `SGLANG_ROUTER_P2C_LOAD_METRIC` settings. `--network host` replaces the single-node `-p` mapping because the two roles run on different hosts.
 
 For the **MI355X Pro / Pro Official FP4** presets, **High-Throughput** sets `MORI_IO_QP_MAX_SEND_WR=32767` and `MORI_IO_QP_MAX_CQE=32768` on both MORI roles. Low-Latency and Balanced use the transport's default queue sizes. The send-queue backoff timeout uses MORI's default of 5 seconds.
 
 #### Role-based configuration
 
-Select **MI355X → Pro Official → FP4 → Multi-Nodes**, then a strategy and role. The commands use the [submitted recipe at `df5e433239d7`](https://github.com/SemiAnalysisAI/InferenceX/blob/df5e433239d72106529ece4dd97cc36e4c3adf4c/inferencex-e2e/benchmarks/multi_node/srt-slurm-recipes/dsv4/sglang/mi355x-fp4/agentx/disagg-umbp-dspark.yaml), with cluster-specific paths replaced by local placeholders and benchmark acceptance simulation removed. The Pro Official commands additionally apply the kernel and routing updates described below.

 The decode role's `--cuda-graph-bs-decode` then has to cover `N*2 / attn_dp_size`, the per-rank batch. The strategy presets apply both rules: decode graphs cover 1–32, 1–96, and 1–64, respectively.

 The panel keeps its c16 / c48 / c256 strategy presets. Apply the following overrides to the **Multi-Nodes** commands to reproduce the optimized recipe's endpoints. Here `cN` means a target concurrency of N.
