Add FLUX.2 model inference testing for the SGLang DLC image, which already ships the sglang.multimodal_gen diffusion stack (diffusers, etc.) but previously had no diffusion test coverage or SageMaker serving path. - model-tests: validate FLUX.2-small-decoder (AutoencoderKLFlux2) via a VAE decode test, since the distilled decoder is a pipeline component rather than a servable text-to-image model. - sagemaker_entrypoint.sh: add an SM_SGLANG_ENGINE gate (default "llm", unchanged) so SM_SGLANG_ENGINE=diffusion launches sglang.multimodal_gen.runtime.launch_server instead of the LLM engine. - sagemaker test: deploy FLUX.2-klein-4B via the diffusion engine and assert /v1/images/generations returns image data.
Revert the SageMaker diffusion endpoint test and the SM_SGLANG_ENGINE entrypoint gate. Those served FLUX.2-klein-4B (the full pipeline), not FLUX.2-small-decoder, which is what this change is about. The distilled VAE decoder is a pipeline component and is validated by the model-tests VAE decode test; no entrypoint change is needed for it.

Replace the diffusers-only VAE decode test with a real SGLang serving test. The decode test loaded AutoencoderKLFlux2 via diffusers and never exercised SGLang, so it did not validate SGLang's diffusion serving path. - sagemaker_entrypoint.sh: add an SM_SGLANG_ENGINE gate (default "llm", unchanged) so SM_SGLANG_ENGINE=diffusion launches sglang.multimodal_gen.runtime.launch_server instead of the LLM engine. - sagemaker test: deploy FLUX.2-klein-4B (the ungated, servable FLUX.2 pipeline) via the diffusion engine and assert /v1/images/generations returns image data. - drop the sglang_flux_vae_decode_test.sh script and its model-tests entry.

Pre-existing go/stdlib CVE compiled into mooncake's libetcd_wrapper.so, same class as the other mooncake go/stdlib entries already allowlisted. Not patchable without an upstream mooncake rebuild on Go 1.26.5+. Added to both the sglang (ec2) and sglang_server (sagemaker) allowlists.

Adds a real SGLang serving test for FLUX.2 diffusion on SageMaker. The SGLang DLC image ships the
sglang.multimodal_gendiffusion stack but the SageMaker entrypoint hardcoded the LLM engine, so diffusion pipelines could not be served.Changes
scripts/docker/sglang/sagemaker_entrypoint.sh: newSM_SGLANG_ENGINEgate — defaultllm(existing behavior unchanged);diffusionlaunchessglang.multimodal_gen.runtime.launch_server. The control var is excluded from theSM_SGLANG_*→--flagmapping.test/sglang/sagemaker/test_sm_endpoint.py: deployFLUX.2-klein-4B(the ungated, servable FLUX.2 pipeline) with the diffusion engine and assert/v1/images/generationsreturns image data.Testing: FLUX.2-klein-4B verified serving end-to-end on an L40S via
sglang.multimodal_gen— pipeline recognized (Qwen3 text encoder →Flux2Transformer2DModel→AutoencoderKLFlux2),/healthok,/v1/images/generationsreturned a generated image. Backward-compatible — existing LLM SageMaker images are unaffected (engine defaults tollm).
