Merge-window drift broke the new environment-variable ratchet on main (build 14119): #6255 added the VLLM_OMNI_ASYNC_OUTPUT_TIMEOUT read in the diffusion engine and #6362 removed the last package reference to ROSVOT_SOURCE_DIR, both after #6217's CI run. - Classify VLLM_OMNI_ASYNC_OUTPUT_TIMEOUT as PUBLIC_OMNI and document it in the environment-variables reference page. - Drop the stale ROSVOT_SOURCE_DIR model-specific row now that the SoulX-Singer implementation is gone. - Update the reviewed snapshot counts and disposition tables to match.

Configuration Options
This section lists the most common options for running vLLM-Omni.
For options within a vLLM Engine, please refer to the vLLM 0.26 configuration guide.
Each model defines fixed topology in a registered PipelineConfig and runtime
overrides in a deploy YAML.
For process-level settings shared by the CLI, deploy YAML, workers, and model integrations, see Environment Variables.
For a specific example, see the Qwen2.5-Omni deploy config. The matching frozen pipeline topology lives at vllm_omni/model_executor/models/qwen2_5_omni/pipeline.py.
For an introduction, see Pipeline and deploy configurations.
