 Follow the AMD overrides in [upstream recipe #946](https://github.com/vllm-project/recipes/pull/946): `VLLM_ROCM_USE_AITER=1`, `VLLM_ROCM_USE_AITER_MOE=1`, and `--moe-backend aiter_triton_mxfp4_bf16`. The recipe pins `semianalysis_cc_traces_weka_062126` (the unfiltered corpus) via `WEKA_LOADER_OVERRIDE`. KV stays GPU-resident; Engram follows upstream AMD defaults. Do not copy the NVIDIA `--engram-config` option: upstream currently rejects it on ROCm. The MI355X launcher uses the shared HF cache and mounts this model's repository at `/ix`, and exports `INFMAX_CONTAINER_WORKSPACE=/ix` so AgentX dependencies and outputs resolve inside that mount.

The tag was published to Docker Hub on 2026-09-11 after AMD verification; it returned HTTP 404 in run 34466680355 before publication. Engram behavior and serving compatibility still require GPU validation. Follow the [AgentX procedure](./eval-agentx-procedures.md#7-run-agentx-fast-feedback-versus-canonical-evidence) for runtime evidence; local generation and registry metadata are not GPU proof.
