+    ``upload_pipeline.py --upload <platform>/bootstrap-upload-steps.yml``.
+  - Injects ``if`` by step ``key`` from skip-ci and uploads child steps (image build, L2–L5 upload).
+  - Detect docs-only, pytest skip-mark-only, or combined skip-ci from git diff.
+  - When only CI level YAML changes, enable **L2/L3** upload steps for affected levels only.
+
+Test pipeline mode (e.g. test-merge.yml):
+  - Drop steps whose ``source_file_dependencies`` do not match changed files.
+  - Expand uploader-only ``mirror_hardwares: l4_1`` into ``agents`` (+ optional ``image``
+    for NPU) + ``plugins`` (see ci_mirror_hardwares.yml).

-"""Render and optionally upload Buildkite pipeline YAML with diff-aware logic.
-
-Bootstrap mode (pipeline.yml with __IMAGE_BUILD_IF__ placeholders):
-  - Detect docs-only, pytest skip-mark-only, or combined docs+skip-mark PR/main changes and
-    substitute skip-ci ``if`` expressions.
-
-Test pipeline mode (e.g. test-merge.yml):
-  - Drop steps or groups whose ``source_file_dependencies`` do not match changed files.
-  - ``source_file_dependencies`` may be set on a leaf step or on a group step.
-  - Always strip ``source_file_dependencies`` from uploaded YAML (Buildkite does not
-    recognize this uploader-only key).
-
-Usage:
-  python3 upload_pipeline.py [--upload] [--all | --e2e] <pipeline.yml>
-
-  # Bootstrap (replaces upload_pipeline_with_skip_ci.sh):
-  python3 upload_pipeline.py --upload .buildkite/pipeline.yml
-
-  # Test pipeline (replaces upload_test_pipeline_with_diff_skip.py):
-  python3 upload_pipeline.py --upload .buildkite/test-merge.yml
-
-  # Full suite (rebase pipeline): keep all steps, still strip the uploader-only key:
-  python3 upload_pipeline.py --upload --all .buildkite/test-merge.yml
-
-  # Nightly L2 E2E only: keep the E2E Test group, ignore source_file_dependencies:
-  python3 upload_pipeline.py --upload --e2e .buildkite/test-ready.yml

+# LingBot-Video Benchmarks
+
+These manual benchmarks compare the upstream LingBot-Video implementation with
+vLLM-Omni. Run all commands from the repository root.
+
+| Benchmark | Script | Purpose |
+|-----------|--------|---------|
+| Dense pipeline parity | `dense_pipeline_parity.py` | Compare generated videos and report MAE, MSE, PSNR, latency, and optional steady-state timings |
+| MoE numerical parity | `moe_transformer_parity.py` | Check bitwise parity for the sparse MoE block and the full MoE transformer |
+
+Both benchmarks require a local LingBot-Video checkout and local model files.
+They do not run in CI.
+
+## Dense pipeline parity
+
+The dense benchmark launches the upstream Diffusers inference script and the
+vLLM-Omni offline example with identical prompts and sampling parameters. It
+then compares the decoded MP4 frames.
+
+```bash
+CUDA_VISIBLE_DEVICES=0 \
+python benchmarks/lingbot_video/dense_pipeline_parity.py \
+  --model /path/to/lingbot-video-dense-1.3b \
+  --official-repo /path/to/lingbot-video \
+  --output-dir /tmp/lingbot_dense_parity
+```
+
+Use `--runs N` to additionally measure repeated in-process vLLM-Omni
+requests. The video comparison reports MAE, MSE, and PSNR; it is an end-to-end
+pipeline diagnostic rather than a bitwise transformer check.
+
+## MoE numerical parity
+
+The lightweight block comparison uses deterministic weights and inputs to
+cover correction-bias routing, group-limited top-k, routed experts, FP32
+scatter-weighted restore, padding masks, and the shared expert.
+
+```bash
+CUDA_VISIBLE_DEVICES=0 \
+python benchmarks/lingbot_video/moe_transformer_parity.py \
+  --scope block \
+  --official-repo /path/to/lingbot-video \
+  --output-json /tmp/lingbot_moe_block_parity.json
+```
+
+The full comparison loads the upstream and vLLM-Omni 30B transformers
+sequentially and compares their output tensors. It requires a CUDA device with
+`torch._grouped_mm` and enough memory for one 30B BF16 transformer.
+
+```bash
+CUDA_VISIBLE_DEVICES=0 \
+python benchmarks/lingbot_video/moe_transformer_parity.py \
+  --scope transformer \
+  --official-repo /path/to/lingbot-video \
+  --model /path/to/lingbot-video-moe-30b-a3b \
+  --output-json /tmp/lingbot_moe_transformer_parity.json
+```
+
+For the correctness oracle, the upstream transformer uses
+`diffusers:_native_math` and vLLM-Omni uses
+`TORCH_SDPA + SDPBackend.MATH`. The command exits with a nonzero status unless
+the selected comparisons are bitwise equal.

+# Composable parallel strategies
+
+In vLLM-Omni, the `composable_parallel` system layers a declarative *parallel strategy* on top of the existing stage configs. A strategy YAML maps each pipeline stage (by its `model_stage` name) to a stack of axis declarations — one per parallelism dimension — that the engine translates into per-stage parallel sizing (`tensor_parallel_size`, `data_parallel_size`, `pipeline_parallel_size`, expert-parallel toggle, replica count) and, when relevant, an orchestrator-wide load-balancer policy.
+
+Strategies are intentionally narrow: each one only writes the axes it declares, leaving every other engine arg untouched. This makes a strategy file a small, reusable overlay you can swap independently of the deploy YAML (see `configuration/stage_configs.md`).
+
+!!! note
+    Composable parallel is **opt-in**. Passing `--strategy-config <path/to/strategy.yaml>` overlays the derived sizing onto the registry-merged stages *before* any CLI overrides are applied. When `--strategy-config` is omitted, stages remain exactly as their deploy YAML produces them.
+
+## Top-level schema reference
+
+A strategy file has a single top-level mapping, `strategies`, keyed by the `model_stage` name of each stage you want to overlay. Each value is a list of axis declarations (see [StrategySpec fields](#strategyspec-fields) below).
+
+| Field | Type | Required | Default | Description |
+|-------|------|----------|---------|-------------|
+| `strategies` | `dict[str, list]` | required | — | Maps `model_stage` name (e.g. `thinker`, `talker`, `code2wav`, `dit`) to a list of axis declarations. The key MUST be the stage name, not the integer `stage_id`. See `vllm_omni/config/composable_parallel/strategy_loader.py`. |
+
+### StrategySpec fields
+
+Each entry in a stage's list becomes one `StrategySpec` (see `vllm_omni/config/composable_parallel/spec.py`). The loader fills in `routing` and `aggregation` from per-kind defaults, so the file stays compact.
+
+| Field | Type | Required | Default | Description |
+|-------|------|----------|---------|-------------|
+| `axis` | str | required | — | Mesh-axis kind. One of `tp`, `dp`, `pp`, `ep`, `stage_replica` (wired today) or `sp_ulysses`, `sp_ring`, `cfg`, `vae_pp`, `hsdp`, `stage_pp`, `cp` (reserved; declaring one raises `AxisTranslationError` at translate time). See `MeshAxisKind` in `vllm_omni/config/composable_parallel/spec.py`. |
+| `size` | int | required | — | Axis degree. Must be `> 0`. |
+| `routing` | str | optional | per-kind default | Stateless routing policy. Accepted only for `dp` / `stage_replica`; other kinds reject it. Values: `random`, `round_robin`, `least_queue`. (`hash` is recognised but currently raises `NotImplementedError`.) See `RouteByStage` in `vllm_omni/config/composable_parallel/routing.py`. |
+| `l1_owner` | str | optional | per-kind default | Overrides which layer owns request routing for this axis. `engine` for `tp`/`dp`/`pp`/`ep`, `delegated` for `stage_replica`. Recorded into `shard_extension`. |
+| `name` | str | optional | axis kind | Human-readable label for this spec, used in error messages. |
+
+Two additional `StrategySpec` slots — `layer_hook_specs` and `kernel_specs` — let advanced authors bind layer-walker hook IDs (`LayerHookSpec`) or kernel IDs (`KernelSpec`) onto an axis. These are not exposed by the YAML loader today and are intended for programmatic construction. See `vllm_omni/config/composable_parallel/spec.py` for the dataclasses.
+
+### CLI flags
+
+| Flag | Description |
+|------|-------------|
+| `--strategy-config PATH` | Path to a `strategy.yaml`. Only takes effect on registry-based deploy paths (`--deploy-config` or the bundled default deploy YAML). Its derived sizing is overlaid onto the merged stages *before* CLI overrides. |
+| `--omni-lb-policy POLICY` | Orchestrator-wide load-balancer policy. Strategy-derived from any `stage_replica` axis; an explicit CLI value wins and must match the derived one or `AsyncOmniEngine` raises `Conflicting load-balancer policy` at construction. |
+
+## Sub-schemas
+
+### `axis`
+
+The set of recognised axis kinds is the `MeshAxisKind` enum in `vllm_omni/config/composable_parallel/spec.py`:
+
+```yaml
+# Translatable today (see `_SUPPORTED_KINDS` in translator.py).
+axis: tp              # tensor parallel — sets tensor_parallel_size
+axis: dp              # engine data parallel — sets data_parallel_size (vLLM's intra-engine DP LB)
+axis: pp              # pipeline parallel — sets pipeline_parallel_size
+axis: ep              # dense expert parallel — sets enable_expert_parallel=True; size must equal tp*dp
+axis: stage_replica   # omni-coordinator-level replica fan-out — sets num_replicas + omni_lb_policy
+
+# Reserved (raise AxisTranslationError today; declared in the type system for forward compat).
+axis: sp_ulysses
+axis: sp_ring
+axis: cfg
+axis: vae_pp
+axis: hsdp
+axis: stage_pp
+axis: cp
+```
+
+### `routing`
+
+The full closed hierarchy lives in `vllm_omni/config/composable_parallel/routing.py` (`Broadcast`, `PartitionByHash`, `ShardSequence`, `ShardSpatial`, `RouteByExpert`, `PipelineMicrobatch`, `DuplicateWithCondTag`, `RouteByStage`). For YAML authors only `RouteByStage` is exposed as a `routing:` string, and only for `dp` / `stage_replica` axes (other axes have fixed routing — `tp`/`ep` broadcast, `pp` microbatch). Recognised policies:
+
+```yaml
+routing: random         # uniform-random across replicas/DP ranks
+routing: round_robin    # cycle through replicas/DP ranks (the default for dp/stage_replica)
+routing: least_queue    # send to the replica with the smallest backlog
+# routing: hash         # recognised but raises NotImplementedError; no key-stable balancer yet
+```
+
+### `aggregation`
+
+Aggregation is filled in automatically by the loader (`_default_aggregation` in `vllm_omni/config/composable_parallel/strategy_loader.py`) from the axis kind, so users do not author it:
+
+| Axis kind | Aggregation pattern |
+|-----------|---------------------|
+| `tp`, `ep` | `TakeRank` (all ranks agree; pick one) |
+| `dp`, ep (in some flows) | `Union` (disjoint replica results) |
+| `pp` | `StitchPipeline` |
+| `stage_replica` | `FanInByStage` |
+
+Full pattern hierarchy: `TakeRank`, `Union`, `GatherDim`, `AllGather`, `StitchSpatial`, `StitchPipeline`, `Combine`, `FanInByStage` (see `vllm_omni/config/composable_parallel/aggregation.py`).
+
+## Precedence
+
+From highest to lowest, when the same axis is touched by multiple layers:
+
+1. **CLI overrides** (`--tensor-parallel-size`, `--stage-overrides`, `--omni-lb-policy`, etc.). A CLI value always wins; a warning is emitted whenever it overrides a strategy-declared axis (see `_reconcile_strategy_with_cli` in `vllm_omni/config/config_factory.py`).
+2. **Strategy YAML** (`--strategy-config`). Derived sizing is written onto the merged stages with *conflict-on-explicit* semantics — if the deploy YAML already set a value to something different, application raises `StrategyApplyError`.
+3. **Deploy YAML** (`--deploy-config` or the bundled `vllm_omni/deploy/<model_type>.yaml`).
+4. **Parser defaults.**
+
+After CLI overrides land, the device-layout guard re-runs (`check_device_layout`, called from `_reconcile_strategy_with_cli`) against the *effective* `tp * dp * pp * num_replicas` and the resolved `devices` string, so a `devices` value passed through `--stage-overrides` or a `--tensor-parallel-size` value that conflicts with the strategy's world size cannot slip past the pre-spawn check.
+
+## Worked example
+
+### Example 1 — `strategy_tp2.yaml`
+
+Shard the `thinker` stage with TP=2 on top of the bundled Qwen2.5-Omni deploy YAML. Routing is fixed (broadcast) for TP, so no `routing:` field is needed.
+
+```yaml
+# examples/offline_inference/qwen2_5_omni/strategy_tp2.yaml
+strategies:
+  thinker:
+    - axis: tp
+      size: 2
+```
+
+Launch:
+
+```bash
+python3 end2end.py --query-type text --num-prompts 6 \
+    --strategy-config strategy_tp2.yaml \
+    --stage-overrides '{"0": {"devices": "0,1"}, "1": {"devices": "2"}, "2": {"devices": "2"}}'
+```
+
+Effective `OmniParallelConfig` per stage after the overlay (see `OmniParallelConfig` in `vllm_omni/config/composable_parallel/translator.py`):
+
+| Stage (`model_stage`) | `tensor_parallel_size` | `data_parallel_size` | `pipeline_parallel_size` | `stage_replica_size` | `omni_lb_policy` |
+|-----------------------|------------------------|----------------------|--------------------------|----------------------|------------------|
+| `thinker`             | **2** (from strategy)  | 1                    | 1                        | 1                    | —                |
+| `talker`              | 1                      | 1                    | 1                        | 1                    | —                |
+| `code2wav`            | 1                      | 1                    | 1                        | 1                    | —                |
+
+### Example 2 — `strategy_stage_replica.yaml`
+
+Replicate the `thinker` stage across two independent engines and let omni's StagePool round-robin requests across them.
+
+```yaml
+# examples/offline_inference/qwen2_5_omni/strategy_stage_replica.yaml
+strategies:
+  thinker:
+    - axis: stage_replica
+      size: 2
+      routing: round_robin
+```
+
+Launch:
+
+```bash
+python3 end2end.py --query-type text --num-prompts 6 \
+    --strategy-config strategy_stage_replica.yaml \
+    --stage-overrides '{"0": {"devices": "0,1"}, "1": {"devices": "2"}, "2": {"devices": "2"}}'
+```
+
+Effective per-stage config and the derived orchestrator knob:
+
+| Stage (`model_stage`) | `tensor_parallel_size` | `stage_replica_size` | `omni_lb_policy` (derived) |
+|-----------------------|------------------------|----------------------|----------------------------|
+| `thinker`             | 1                      | **2**                | **`round-robin`**          |
+| `talker`              | 1                      | 1                    | —                          |
+| `code2wav`            | 1                      | 1                    | —                          |
+
+The derived `omni_lb_policy = round-robin` is **not** written into any stage's engine args. Instead it is surfaced on `StrategyApplyResult.omni_lb_policy` and applied once at orchestrator construction by `AsyncOmniEngine._apply_strategy_lb_policy` (see `vllm_omni/engine/async_omni_engine.py`, lines 1107–1134). If you also pass `--omni-lb-policy round-robin` the values must match; passing a different value raises `Conflicting load-balancer policy`.
+
+## Per-field deep-dive
+
+### `name`
+
+Default: the axis kind (e.g. `"tp"`).
+
+Human-readable label that appears in `AxisTranslationError` and `StrategyApplyError` messages. Set it to disambiguate two stages declaring the same axis kind when scanning logs.
+
+### `mesh_axis` (`axis` + `size`)
+
+Default: no default — both fields are required.
+
+`axis` chooses the parallelism dimension; `size` is its degree. Five kinds are wired end-to-end today (`tp`, `dp`, `pp`, `ep`, `stage_replica`); the remaining kinds in `MeshAxisKind` are reserved and raise `AxisTranslationError` at translate time so a typo cannot silently become a no-op (see `_SUPPORTED_KINDS` in `vllm_omni/config/composable_parallel/translator.py`). For `ep`, the size MUST equal `tensor_parallel_size * data_parallel_size`.
+
+### `routing`
+
+Default: per-kind — `RouteByStage(round_robin)` for `dp` and `stage_replica`; `PipelineMicrobatch()` for `pp`; `Broadcast()` for `tp`/`ep` and any other kind.
+
+User-facing string only on `dp` and `stage_replica` axes. The four recognised values are `random`, `round_robin`, `least_queue`, `hash`; `hash` is rejected today with `NotImplementedError`. See `RouteByStage` in `vllm_omni/config/composable_parallel/routing.py`.
+
+### `l1_owner`
+
+Default: per-kind — `engine` for `tp`/`dp`/`pp`/`ep`, `delegated` for `stage_replica`.
+
+Overrides which layer owns request routing along this axis. `engine` means vLLM realizes routing intra-engine; `delegated` means the omni coordinator owns routing across independent replicas. Set this only when overriding the per-kind default in `_DEFAULT_L1_OWNER` (`vllm_omni/config/composable_parallel/translator.py`); invalid values fail fast in `_resolve_l1_owner`.
+
+### `stage_replica` and `omni_lb_policy`
+
+`stage_replica` is *not* a vLLM world dimension; it spins up `size` independent engine replicas of one stage, coordinated by the omni `StagePool` load balancer. The axis writes both:
+
+- The stage's `num_replicas` (a per-stage deploy knob).
+- The pipeline-wide `omni_lb_policy` string (an orchestrator-level knob).
+
+Because `omni_lb_policy` is read once at `AsyncOmniEngine` construction — not from per-stage engine args — only one value is allowed across the whole pipeline. If two stages declare conflicting policies, application raises (see `apply_strategy_specs` in `vllm_omni/config/composable_parallel/apply.py`, lines 253–260). To set this knob manually instead, use `--omni-lb-policy` on the CLI; see [the model stage docs](stage_configs.md) for how stage replicas plug into the orchestrator at runtime.
+
+### `model_stage` keys
+
+Default: no default — required for every entry under `strategies:`.
+
+Strategy keys MUST be `model_stage` *names* (strings), the same labels stage configs use for `engine_args.model_stage` (see [`model_stage` in `stage_configs.md`](stage_configs.md#engine_argsmodel_stage)). Integer `stage_id` values are not accepted; the resolver matches on `model_stage` exactly (`_resolve_stage` in `vllm_omni/config/composable_parallel/apply.py`).
+
+## Common pitfalls
+
+!!! warning "Using `stage_id` integers as keys"
+    Strategy keys are `model_stage` names (str), not integer stage IDs. A file that uses an integer index will raise at apply time:
+
+    ```text
+    StrategyApplyError: strategy role model_stage=0 did not match any stage;
+    available stages: 'thinker'(id=0), 'talker'(id=1), 'code2wav'(id=2)
+    ```
+
+    Use the `model_stage` name (e.g. `thinker`) instead.
+
+!!! warning "Mixing CLI overrides with a strategy on the same axis"
+    A strategy is meant to be the single writer for the axes it declares. If a CLI override (`--tensor-parallel-size 2`, `--stage-overrides '{"0": {"tensor_parallel_size": 2}}'`) sets the same axis, the **CLI value wins** and a warning is emitted from `_reconcile_strategy_with_cli`. The device-layout guard then re-runs against the effective layout, so a CLI override that breaks `tp * dp * pp * num_replicas` will still fail fast at config time.
+
+!!! warning "Conflicting `omni_lb_policy` across stages"
+    `omni_lb_policy` is a single pipeline-wide knob. If two `stage_replica` axes in different stages derive different policies, `apply_strategy_specs` raises:
+
+    ```text
+    StrategyApplyError: role 'talker' derives omni_lb_policy='least-queue-length'
+    but role 'thinker' already derived 'round-robin'. The load-balancer policy is
+    pipeline-wide; only one value is allowed.
+    ```
+
+    Make the policies match, drop one, or supply the value explicitly via `--omni-lb-policy`.

-# Multi-Level Automated Testing System Documentation
-
-## Document Overview
-
-This testing system aims to build a complete, efficient, and well-structured quality assurance framework for the development, integration, and release of model services. It draws on the concept of the test pyramid from modern software engineering, progressively expanding testing activities from basic code logic verification to complex end-to-end (E2E) functionality, performance, accuracy, and even long-term stability validation.
-
-Through five levels (L1-L5) and common (Common) specifications, the system clarifies the testing objectives, scope, execution frequency, and required resources for different development stages (e.g., each commit, PR merge, daily build, pre-release). This ensures that models meet high standards for functionality, performance, and reliability across various deployment scenarios (online serving and offline inference).

-## Common Specifications
-
-Before entering specific testing levels, the project establishes two common specifications aimed at standardizing the development process and quickly locating issues.
-
-1.  ***PR Checklist ([Tests Style](../ci/tests_style.md))***: This template defines the self-check items that must be completed before submitting a code review (Pull Request). It ensures that each code change meets basic requirements such as code style, dependency updates, and documentation synchronization before entering the automated testing pipeline, serving as the first manual line of defense for quality assurance.
-2.  ***CI Failure Explanation ([CI Failures](../ci/failures.md))***: This document archives and explains common failure patterns in the Continuous Integration (CI) pipeline, error log interpretation, and preliminary troubleshooting steps. It helps developers and testers quickly diagnose the causes of automated test failures, improving problem-solving efficiency.
-
-## Notes
-
-### Diff-aware Buildkite uploads (`source_file_dependencies`)
-
-L2 (`.buildkite/test-ready.yml`) and L3 (`.buildkite/test-merge.yml`) pipelines can **skip unrelated GPU jobs at upload time** based on the PR diff. This is implemented by `.buildkite/scripts/upload_pipeline.py`, which filters steps before calling `buildkite-agent pipeline upload`.
-
-#### What `source_file_dependencies` is
-
-- A **uploader-only** YAML key on a Buildkite step or group. **Buildkite does not understand it**; `upload_pipeline.py` always **removes** it from the YAML that is uploaded.
-- A list of path **prefixes** (directories or individual files). If **any** changed file in the diff equals a prefix or starts with `prefix/`, the step is kept; otherwise the step (or entire group) is **omitted** from the uploaded pipeline.
-
-#### When filtering runs
-
-| Build context | Changed files used for matching |
-| --- | --- |
-| Pull request | `git diff --name-only origin/<base>...<BUILDKITE_COMMIT>` |
-| `main` branch push | `git diff --name-only <commit>^..<commit>` |
-| Other (e.g. local dry-run, non-PR branch) | Diff cannot be resolved → **no filtering**; all steps are uploaded and `source_file_dependencies` is still stripped |
-
-Docs-only PRs are handled earlier in bootstrap (`pipeline.yml`) via skip-ci logic; `source_file_dependencies` applies only to the **uploaded** L2/L3 test pipelines.
-
-#### Where it is configured
-
-| Level | Pipeline file | Upload entry |
-| --- | --- | --- |
-| L2 | `.buildkite/test-ready.yml` | `upload_pipeline.py --upload .buildkite/test-ready.yml` (from `pipeline.yml`) |
-| L3 | `.buildkite/test-merge.yml` | `upload_pipeline.py --upload .buildkite/test-merge.yml` (from `pipeline.yml`) |
-
-Steps **without** `source_file_dependencies` are always uploaded (subject to the usual label conditions: `ready` for L2, `merge-test` for L3).
-
-#### Current skip policy (L2 / L3)
-
-To balance CI cost and coverage:
-
-- **Always run** (no `source_file_dependencies`): baseline groups outside E2E Test—e.g. Simple Test, Diffusion unit tests, Engine/Model Executor, Distributed, Custom Pipeline, Entrypoints (L2), LoRA / Entrypoints (L3).
-- **Diff-gated** (`source_file_dependencies` set): **every leaf job under the E2E Test group** in `test-ready.yml` and `test-merge.yml`, regardless of queue (`mithril-h100-pool`, `gpu_1_queue`, or `gpu_4_queue`). Each step lists the smallest set of prefixes that should trigger it—typically:
-  - pytest file(s) exercised by the job (online and/or offline);
-  - model code under `vllm_omni/model_executor/models/` or `vllm_omni/diffusion/models/`;
-  - related `vllm_omni/model_executor/stage_input_processors/` and `vllm_omni/deploy/*.yaml` when applicable.
-
-Adding a new E2E step: add `source_file_dependencies` on the leaf job with those prefixes. Prefer **per-step** deps rather than a broad group-level list unless every child shares the same paths.
-
-#### YAML examples
-
-H100 E2E (kubernetes / `mithril-h100-pool`):
-
-```yaml
-      - label: "Diffusion · Qwen Image Test"
-        source_file_dependencies:
-          - tests/e2e/online_serving/test_qwen_image.py
-          - vllm_omni/diffusion/models/qwen_image/
-        commands:
-          - pytest -s -v tests/e2e/online_serving/test_qwen_image.py -m 'core_model' ...
-        agents:
-          queue: "mithril-h100-pool"
-```
-
-Docker E2E (`gpu_1_queue` / `gpu_4_queue`)—same key, same upload-time filtering:
-
-```yaml
-      - label: "TTS · Qwen3-TTS CustomVoice Test"
-        source_file_dependencies:
-          - tests/e2e/online_serving/test_qwen3_tts_customvoice.py
-          - vllm_omni/model_executor/models/qwen3_tts/
-          - vllm_omni/model_executor/stage_input_processors/qwen3_tts.py
-          - vllm_omni/deploy/qwen3_tts.yaml
-        commands:
-          - pytest -s -v tests/e2e/online_serving/test_qwen3_tts_customvoice.py ...
-        agents:
-          queue: "gpu_4_queue"
-```
-
-A **group** may also define `source_file_dependencies`; nested steps inherit filtering as a unit—the whole group is dropped if no prefix matches.
-
-#### Local dry-run
-
-```bash
-# Render filtered YAML to stdout (no upload)
-python3 .buildkite/scripts/upload_pipeline.py .buildkite/test-ready.yml
-
-# Confirm uploader-only keys are stripped
-python3 .buildkite/scripts/upload_pipeline.py .buildkite/test-merge.yml | grep source_file_dependencies
-# (no output expected)
-```
-
-On a PR build, Buildkite logs from `upload_pipeline.py` include lines such as `skip '…' (no changes under …)` for omitted steps.
-
-#### Related
-
-- Implementation: `.buildkite/scripts/upload_pipeline.py`
-- L2/L3 diff skip does **not** replace label-based triggers (`ready`, `merge-test`); it only reduces which steps appear **after** the pipeline is already scheduled.
-
-### Test helper environment variables
-
-Some shared helpers under `tests/helpers/` honor optional environment variables for local debugging. These are **not** set in CI by default.
-
-| Variable | Accepted values | Description |
-| -------- | --------------- | ----------- |
-| `VLLM_OMNI_KEEP_REQUEST_MEDIA` | `1`, `true`, `yes` (case-insensitive) | When enabled, temporary WAV files created by `tests.helpers.media.convert_audio_bytes_to_text` are **not** deleted when the pytest process exits. By default, each call writes a unique file under the system temp directory via `tempfile.mkstemp` and registers `atexit` cleanup. Use this when debugging audio output validation (Whisper transcription, keyword checks, text–audio similarity). The saved path is logged as `audio data is saved: <path>`. |
-
-Example (Linux / macOS):
-
-```bash
-export VLLM_OMNI_KEEP_REQUEST_MEDIA=1
-pytest -s -v tests/e2e/online_serving/test_qwen3_omni.py -k test_mix_to_text_audio
-```
-
-Example (Windows PowerShell):
-
-```powershell
-$env:VLLM_OMNI_KEEP_REQUEST_MEDIA = "1"
-pytest -s -v tests/e2e/online_serving/test_qwen3_omni.py -k test_mix_to_text_audio
-```

-## Chapter 1: L1 & L2 Level Testing - Unit Testing and Basic End-to-End Verification
-
-### 1.1 Testing Purpose
-
-L1 and L2 level testing form the foundation of the quality assurance system. L1 level testing focuses on verifying the internal logic correctness of code units (e.g., functions, classes), ensuring each independent component behaves as designed.
-
-L2 level testing builds upon L1 by introducing GPU resources and verifying that the end-to-end (E2E) process of the model in basic deployment scenarios is smooth. For example, it uses dummy models to confirm that core interfaces like the inference pipeline, output format, and streaming response work properly. The common goal of these two levels is to provide developers with rapid feedback, discovering and fixing issues early in the development cycle.
-
-
-
-### 1.2 Testing Content and Scope
-
--   ***L1 (Unit & Logic Testing)***:
--   -   ***Scope***: Tests internal functions and methods of core components such as `entrypoints`, `models`.
-    -   ***Focus***: Branch coverage, exception handling, algorithm logic correctness. Does not involve external dependencies or the complete service stack.
-    -   ***Time Cost***: Execution time is controlled within ***15 minutes*** to ensure fast feedback.
--   ***L2 (Basic End-to-End Testing)***:
--   -   ***Scope***: Covers two basic deployment scenarios: `online` (serving) and `offline` (inference).
-    -   ***Focus***: Uses `dummy` weights (via deploy YAML patching at `core_model`) or lightweight real models to verify that the entire chain from request input to result output works normally, including output data structure, streaming (stream) support, and **cheap payload checks** at `--run-level core_model` (see below). Also includes some unit tests that require launching independent service instances.
-    -   ***L2 response validation (`core_model`)***: Implemented in `tests/helpers/assertions.py` and invoked by `OpenAIClientHandler` based on `--run-level`. At L2 we require **request success** plus minimal output sanity—not full accuracy:
-        -   **Speech / TTS** (`assert_audio_speech_response`): decoded audio must be present and non-empty (or exceed `min_audio_bytes` when set in `request_config`); `response_format` must match the returned content-type (e.g. `wav`, `pcm`). Whisper transcript similarity, PCM HNR, and preset-voice gender checks run only at L3+.
-        -   **Diffusion** (`assert_diffusion_response`): at least one non-empty image, video, or audio artifact. Resolution/frame-count parity and other deep checks run only at L3+.
-        -   **Omni multimodal** (`assert_omni_response`): L2 asserts successful completion; keyword, transcript, and cross-modal similarity checks run only at L3+.
-    -   ***Characteristic***: Requires ***GPU*** resources to perform model computations.

-### 1.3 Test Directory and Execution Files
-
-A clear directory structure is key to managing test cases efficiently.
-
--   ***L1 Test Directory***: `/tests/{component_name}/test_xxx.py`
--   -   Here, `{component_name}` corresponds to modules in the source code, such as `distributed`, `entrypoints`, etc., and `test_xxx.py` is the specific test file.
--   ***L2 Test Directory***:
--   -   Online Serving: `/tests/e2e/online_serving/test_{model_name}.py`
-    -   Offline Inference: `/tests/e2e/offline_inference/test_{model_name}.py`
-
-### 1.4 Execution Method and Example
-
--   ***Trigger Timing***: **`PR with ready label`**. That is, when a developer adds a "ready for review" or similar label to a PR on platforms like GitHub, L1 and L2 tests are automatically triggered.
--   ***Diff-aware step skipping***: On L2, **E2E Test** jobs may be omitted at pipeline upload when the PR diff does not touch their [`source_file_dependencies`](#diff-aware-buildkite-uploads-source_file_dependencies) prefixes (H100 and docker queues alike); non-E2E groups still always upload. See [Diff-aware Buildkite uploads](#diff-aware-buildkite-uploads-source_file_dependencies).
--   ***Execution Environment***: L1 uses ***CPU*** environment; L2 requires ***GPU*** environment.

-## Chapter 2: L3 Level Testing - Core Integration, Performance, and Accuracy Verification
-
-### 2.1 Testing Purpose
-
-L3 level testing executes after code is merged into the main branch. Its core purpose is to verify the integration effect, key performance indicators, and output accuracy of ***real models*** in ***multiple deployment scenarios***
-
-. It acts as the "quality gatekeeper" for the main branch, ensuring that no merge breaks the core capabilities of the model service. Testing needs to provide clear conclusions within a relatively short time (<30min), balancing test depth with feedback speed.
-
-
-
-### 2.2 Testing Content and Scope
-
--   ***Deployment Scenarios***: Covers richer `online` and `offline` deployment configurations, which may include different hardware configurations, batch sizes, concurrency levels, etc.
--   ***Core Verification***:
--   1.  ***Inference Functionality***: Ensures real models can perform forward computation normally and return results.
-    2.  ***Accuracy Compliance***: Verifies that the model's evaluation metrics (e.g., accuracy) meet the expected baseline, preventing code changes from introducing accuracy issues.
-    3.  ***Important Performance***: Verifies whether performance (e.g., P99 latency, throughput) in core scenarios meets preset thresholds.
--   ***L3 response validation (`advanced_model`)***: At `--run-level advanced_model`, `tests/helpers/assertions.py` adds semantic checks on top of L2 payload gates (see Chapter 1):
-    -   **Speech / TTS** (`assert_audio_speech_response`): Whisper transcript of returned audio vs `request_config["input"]` (cosine similarity &gt; 0.9 when input text is set); optional `min_audio_bytes` floor; PCM harmonic-to-noise ratio when `response_format` is `pcm`; **preset voice gender** via `_assert_preset_voice_gender_from_audio` when `voice` matches a known preset in `_PRESET_VOICE_GENDER_MAP` (pitch/F0-based classifier; skipped for unknown voices or `pcm` output).
-    -   **Omni multimodal** (`assert_omni_response`): non-empty text/audio outputs; `key_words` in transcript or text; text–audio similarity / containment; preset **`speaker`** gender check (same helper as TTS).
-    -   **Diffusion** (`assert_*_diffusion_response`): image/video dimension and frame-count parity with request parameters where configured.
-    -   **Accuracy suites**: pixel/video similarity and metric baselines under `/tests/e2e/accuracy/` (separate from inline helper assertions).
-
-### 2.3 Test Directory and Execution Files
-
--   ***Functional Testing***:
--   -   Online Serving: `/tests/e2e/online_serving/test_{model_name}_expansion.py`
-    -   Offline Inference: `/tests/e2e/offline_inference/test_{model_name}_expansion.py`
-    -   (Note: `_expansion.py` likely means it contains more comprehensive scenario cases compared to L2 tests).
-
-### 2.4 Execution Method and Example
-
--   ***Trigger Timing***: **`PR Merged`**. Automatically triggered after code review is approved and merged into the main branch (typically via `merge-test` label on the PR before merge).
--   ***Diff-aware step skipping***: Same [`source_file_dependencies`](#diff-aware-buildkite-uploads-source_file_dependencies) mechanism as L2—**all E2E Test** leaf steps are diff-gated; other L3 groups always upload. See [Diff-aware Buildkite uploads](#diff-aware-buildkite-uploads-source_file_dependencies).
--   ***Execution Environment***: ***GPU*** servers.
--   ***Script Example***:
-
-???+ example "Test Examples"
-
-    **2.4.1 Mark Declaration Section**
-
-    ```python
-    @pytest.mark.advanced_model
-    @pytest.mark.core_model
-    @pytest.mark.parametrize("omni_server", test_params, indirect=True)
-    ```
-
-    **Explanation**:
-
-    @pytest.mark.advanced_model: Marks the test as L3 merge level (`--run-level advanced_model`): real weights, Whisper/similarity/keyword checks, diffusion deep checks, and **preset voice/speaker gender** validation where applicable. @pytest.mark.full_model: Marks L4 nightly-only suites (e.g. `test_*_expansion.py`, doc examples).
-
-    @pytest.mark.core_model: Marks the test as L1 or L2 level. At `--run-level core_model`, validation is limited to request success plus cheap payload checks (e.g. non-empty audio bytes, response format/content-type, non-empty diffusion outputs)—not Whisper, keyword, or accuracy gates. Deploy YAML may use `load_format: dummy` for fast PR feedback.
-
-    @pytest.mark.parametrize: A parameterization decorator that allows abstracting test data into parameters, enabling reuse of the same test logic across different data configurations. indirect=True indicates that parameters will be passed to the fixture for processing.
-
-    **Notes**: If you believe the test case only needs to execute basic run logic at the PR-level CI, you can mark it only with @pytest.mark.core_model. If you believe it only needs to execute deep validation at merge (L3), use @pytest.mark.advanced_model. For L4 nightly-only expansion and doc-example tests, use @pytest.mark.full_model with `--run-level full_model`. If the test case needs both basic run and deep validation, mark with @pytest.mark.core_model and the appropriate L3/L4 marker (`advanced_model` and/or `full_model`).
-
-    **2.4.2 Test Function Definition and Documentation**
-
-    ```python
-    def test_mix_to_text_audio_001(omni_server, openai_client) -> None:
-        """
-        Test multi-modal input processing and text/audio output generation via OpenAI API.
-        Deploy Setting: default yaml
-        Input Modal: text + audio + video + image
-        Output Modal: text + audio
-        Input Setting: stream=True
-        Datasets: single request
-        """
-    ```
-
-    **Explanation**:
-
-    **Function Naming Convention**: Uses the test_ prefix, describes the test scenario mix_to_text_audio, and the number 001 indicates the first test case for this scenario.
-
-    **Parameter Explanation**:
-
-    omni_server: Omni server instance obtained via fixture, containing model information and configuration.
-
-    openai_client: Unified OpenAI client processing instance, encapsulating request sending and response validation logic.
-
-    Docstring: Describes the test purpose, deployment settings, input/output modalities, streaming settings, and dataset type in detail, providing clear context for test maintenance.
-
-    **2.4.3 Multimodal Data Preparation**
-
-    ```python
-    video_data_url = f"data:video/mp4;base64,{generate_synthetic_video(224, 224, 300)['base64']}"
-    image_data_url = f"data:image/jpeg;base64,{generate_synthetic_image(224, 224)['base64']}"
-    audio_data_url = f"data:audio/wav;base64,{generate_synthetic_audio(5, 1)['base64']}"
-    ```
-
-    **Explanation**:
-
-    **Data Generation Functions**: Use the generate_synthetic_* series of functions to generate synthetic test data, avoiding reliance on external resources and ensuring test reproducibility and stability.
-
-    **Parameter Explanation**:
-
-    Video: width, height, duration_frames
-
-    Image: width, height
-
-    Audio: duration_seconds, channels
-
-    **2.4.4 Request Configuration and Keyword Validation**
-
-    ```python
-    request_config = {
-        "model": omni_server.model,
-        "messages": messages,
-        "stream": True,
-        "key_words": {
-            "audio": ["water", "cricket"],
-            "video": ["sphere", "globe", "circle", "round"],
-            "image": ["square", "quadrate"],
-            "text": ["beijing"]
-        },
-    }
-    ```
-
-    **Explanation**:
-
-    **Model Specification**: Uses omni_server.model to ensure the test aligns with the model configured on the server.
-
-    **Keyword Validation Mechanism**: This is an innovative design of the template to address the specific needs of multimodal testing:
-
-    Audio Keywords: Validate whether the generated text's description of audio content contains expected elements (e.g., "water" for water sounds, "cricket" for cricket sounds). If you provide multiple keywords, the validation is considered successful if at least one keyword is present.
-
-    **Video Keywords**: Validate whether the generated text's description of video content contains expected elements. If you provide multiple keywords, the validation is considered successful if at least one keyword is present.
-
-    Image Keywords: Validate whether the generated text's description of image content contains expected elements. If you provide multiple keywords, the validation is considered successful if at least one keyword is present.
-
-    Text Keywords: Validate whether the generated text contains expected elements. If you provide multiple keywords, the validation is considered successful if at least one keyword is present.
-
-    **2.4.5 Request Execution**
-
-    ```python
-    openai_client.send_omni_request(request_config, request_num=1)  # for omni-understanding models
-    # or
-    openai_client.send_diffusion_request(request_config, request_num=1)  # for diffusion models
-    ```
-
-    **Explanation**:
-
-    **Unified Client**: Uses the OpenAIClientHandler instance to send requests. This client encapsulates error handling, retry mechanisms, and response validation logic.
-
-    **Single Request**: The comment clearly states this is a single-request completion test. For concurrent testing, it can be extended to multiple requests using request_num = n.
-
-    **Implicit Validation**: `send_omni_request`, `send_audio_speech_request`, and `send_diffusion_request` call `assert_*_response` helpers with the session `--run-level`. At `core_model`, checks are limited to success plus cheap payload sanity (non-empty audio/media, format/content-type, optional `min_audio_bytes`). At `advanced_model` and `full_model`, deep validation adds Whisper transcripts, keyword/similarity, diffusion dimension checks, PCM HNR, etc.
-
-    **Audio output debugging**: Deep validation may transcribe returned audio via `convert_audio_bytes_to_text` (Whisper). If an audio keyword or text–audio similarity assertion fails, set `VLLM_OMNI_KEEP_REQUEST_MEDIA=1` before running pytest to keep the intermediate WAV files for inspection (see [Test helper environment variables](#test-helper-environment-variables)).

-## Chapter 3: L4 Level Testing - Full Functionality, Performance, and Documentation Testing
-
-### 3.1 Testing Purpose
-
-L4 level testing is a comprehensive quality audit before a version release. It expands upon L3, executing ***full*** functional scenarios, conducting systematic ***performance stress tests***, and simultaneously verifying the correctness of accompanying ***example documentation***. Its purpose is to perform deep validation of the system during off-peak nighttime hours, providing quality trend reports for daytime development and data support for release decisions.
-
-
-
-### 3.2 Testing Content and Scope
-
--   ***Full Functionality Testing***: Executes all test cases defined in `test_{model_name}_expansion.py`, covering all implemented features, positive flows, boundary conditions, and exception handling.
--   ***Performance Testing***: Uses `tests/dfx/perf/tests/test_qwen_omni.json`, `tests/dfx/perf/tests/test_tts.json`, and diffusion configs in the form `tests/dfx/perf/tests/test_*_vllm_omni.json` (passed to `run_benchmark.py` via `--test-config-file`) to drive performance testing tools for stress, load, and endurance tests, collecting metrics like throughput, response time, and resource utilization.
--   ***Documentation Testing***: Verifies whether the example code provided to users is runnable and its results match the description.
-
-### 3.3 Test Directory and Execution Files
-
--   ***Functional Testing***: Same directories as L3.
--   ***Performance Test Configuration***: `tests/dfx/perf/tests/test_qwen_omni.json`, `tests/dfx/perf/tests/test_tts.json`, and diffusion configs `tests/dfx/perf/tests/test_*_vllm_omni.json` (e.g. `test_qwen_image_vllm_omni.json`)
--   ***Documentation Example Tests***:
--   -   `tests/example/online_serving/test_{model_name}.py`
-    -   `tests/example/offline_inference/test_{model_name}.py`
-
-### 3.4 Execution Method and Example
-
--   ***Trigger Timing***: **`Nightly`**, automatically executed every night.
--   ***Execution Environment***: ***GPU*** server clusters to meet the resource demands of performance testing.
--   ***Script Example***:

-
-## Chapter 4: L5 Level Testing - Stability and Reliability Testing
-
-### 4.1 Testing Purpose
-
-L5 level testing focuses on the performance of model services under ***long-running*** and ***abnormal fault*** scenarios. It aims to uncover deep-seated issues that only manifest under sustained pressure or extreme conditions, such as memory leaks, resource contention, gradual performance degradation, and lack of fault tolerance mechanisms. This is the final, yet crucial, line of defense for ensuring service high availability and production environment robustness.
-
-
-
-### 4.2 Testing Content and Scope
-
--   ***Long-term Stability (Stability) Testing***: Uses JSON under `tests/dfx/stability/tests/` (for example `test_qwen3_omni.json` and `test_wan22.json`) to run the service under moderate load for an extended period (e.g., over 12 hours), monitoring whether metrics like memory/VRAM usage, response time, and throughput degrade over time, and whether the service process remains stable.
--   ***Reliability Testing***: Uses pytest suites under `tests/dfx/reliability/` to inject controlled faults against a **live** `vllm_omni serve` instance (same **`omni_server` / `omni_server_function`** fixture style as E2E). Current suites emphasize **GPU memory pressure** (CUDA sidecar “memory hog”), **worker / runtime process kill** (`SIGKILL` on `VLLM::Worker` for Qwen3-Omni, `multiprocessing.spawn` for Wan2.2 video workers, or `vLLM-Omni::` for HunyuanImage DiT workers), **large multimodal chat**, **`/v1/videos`**, **`/v1/images/generations`**, or **`/v1/audio/speech`** jobs under OOM, **`/health` → 503** and **fast-fail / non-hanging concurrent** requests after kill, and **OpenAI-style 5xx error contracts** (e.g. text vs text+audio under OOM). **Post-fault recovery** checks exist where enabled (some cases may be `skip` while issues are tracked). See the Reliability `<details>` block in Section 4.4 for file-level responsibilities and CI markers (`slow`, `hardware_test`, POSIX-only kill).
-
-### 4.3 Test Directory and Execution Files
-
--   ***Stability Test Configuration***: `tests/dfx/stability/tests/test_qwen3_omni.json`, `tests/dfx/stability/tests/test_wan22.json` (one JSON per model / runner family)
--   ***Reliability Test Suite*** (`tests/dfx/reliability/`):
-    -   `test_reliability_qwen3_omni.py` — Qwen3-Omni chat / multimodal reliability (GPU OOM, process kill, recovery, error contract under `--async-chunk` vs default).
-    -   `test_reliability_wan22.py` — Wan2.2 I2V video API reliability (`/v1/videos` under OOM and process kill, recovery).
-    -   `test_reliability_hunyuan_image.py` — HunyuanImage-3.0-Instruct DiT-only reliability (`/v1/images/generations` under OOM and process kill; deploy `hunyuan_image3_dit.yaml`, H100 × 4).
-    -   `test_reliability_voxcpm2.py` — VoxCPM2 TTS reliability (`/v1/audio/speech` under OOM and process kill; deploy `voxcpm2.yaml`, L4 × 1).
-    -   `helpers.py` — Shared primitives used by current suites: raw HTTP probes for `/v1/chat/completions` and `/health`, OpenAI-style error parsing, GPU OOM sidecar (`inject_gpu_oom` / `stop_gpu_oom_hogs`), and `pgrep`-based process-kill injector construction (`make_process_kill_fault_injector`).
-    -   `conftest.py` — `fault_injector` and `omni_server_after_fault` / `omni_server_after_fault_function` fixtures to run a callable **after** the server is ready.
-    -   `README.md` — Short local run commands for this directory.
-
-### 4.4 Execution Method and Example
-
--   ***Trigger Timing***: **`Weekly`** (weekly) or **`Days before Release`** (several days before a major release). Due to long execution times, the frequency is lower.
--   ***Execution Environment***: ***GPU*** servers, requiring a stable and exclusive testing environment.
--   ***Script Example***:

-For stability testing, the key parameters are:
-
--   **duration_sec**: Total duration (in seconds) during which benchmark traffic is sent. The stability benchmark will keep sending batches until this duration is reached.
--   **request_rate** / **max_concurrency**: Exactly one of them must be specified. They control how the traffic is generated for each batch:
-    -   `request_rate`: Number of requests per second. The benchmark will send `num_prompts_per_batch` requests at the given rate.
-    -   `max_concurrency`: Maximum number of concurrent requests. When this is used, `request_rate` is set to `inf` internally.
--   **num_prompts_per_batch**: Number of prompts sent in each batch. Multiple batches will be executed sequentially within `duration_sec`.
-
-All other optional parameters follow the same rules as the in Chapter 3.4.

-
-#### Purpose and relationship to stability
-
-Reliability tests are **short fault-injection** integration runs (L5 **(b)** in `tests/dfx/reliability/README.md`). They complement **stability** JSON-driven long runs: instead of hours of steady traffic, they **perturb** the server (GPU OOM sidecar, fatal signals on selected processes) and check **failure mode** and **latency bounds** (e.g. chat or `/v1/videos` must not hang under concurrent fault-time load).
-
-#### Directory layout
-
-| Path | Responsibility |
-| ---- | -------------- |
-| `helpers.py` | Shared helpers used by current reliability suites: raw `POST`/`GET` probes (`/v1/chat/completions`, `/health`), OpenAI error parsing (`extract_openai_error_contract_from_bytes`), GPU OOM sidecar lifecycle (`inject_gpu_oom`, `stop_gpu_oom_hogs`), and process-kill injector builder (`make_process_kill_fault_injector`). |
-| `conftest.py` | Pytest fixtures: indirect `fault_injector`, `omni_server_after_fault` / `omni_server_after_fault_function` (run injector after server is ready, then yield server). |
-| `test_reliability_qwen3_omni.py` | Qwen3-Omni: OOM vs **text vs text+audio** error contract, large multimodal chat under OOM, concurrent pressure, **SIGKILL** on `VLLM::Worker`, `/health` → 503 + fast-fail + concurrent chat; optional OOM recovery scenario (may be skipped while tracked in issues). |
-| `test_reliability_wan22.py` | Wan2.2 I2V: large `/v1/videos` under OOM, **SIGKILL** on `multiprocessing.spawn` chain, health / fast-fail / concurrent video requests; optional recovery test (may be skipped). |
-| `test_reliability_hunyuan_image.py` | HunyuanImage DiT-only: large `/v1/images/generations` under OOM, **SIGKILL** on `vLLM-Omni::` workers and serve/tree targets, health / fast-fail / concurrent image requests; some OOM/recovery cases may be skipped while tracked in issues. |
-| `test_reliability_voxcpm2.py` | VoxCPM2: `/v1/audio/speech` under OOM (error contract), **SIGKILL** on `VLLM::` workers and serve/tree targets, health / fast-fail / concurrent speech requests; some OOM cases may be skipped while tracked in issues. |
-| `README.md` | Minimal run / collect examples. |
-
-#### Parametrization and markers
-
-- Each test module defines a **`RELIABILITY_SCENARIOS`** list (`test_name`, `server_params`: model, `stage_config_name` or diffusion `server_args`, etc.). **`create_reliability_omni_server_params()`** in `tests/dfx/conftest.py` resolves stage paths (including XPU substitutions where applicable) and builds **`OmniServerParams`** lists consumed by **`@pytest.mark.parametrize(..., indirect=True)`** on `omni_server` or `omni_server_function`.
-- Cases are tagged **`@pytest.mark.slow`** for weekly / selective CI. GPU-heavy suites use **`@hardware_test(res={"cuda": "H100"}, num_cards=...)`** or **`@hardware_test(res={"cuda": "L4"}, num_cards=1)`** (Qwen3-Omni **2**× H100; Wan2.2 **1**× H100; HunyuanImage DiT **4**× H100; VoxCPM2 **1**× L4).
-- **Process-kill** tests use **`@pytest.mark.skipif(os.name == "nt", ...)`** because injection uses POSIX **`pgrep` / `kill`**.
-
-#### CI trigger
-
-Weekly Buildkite (`.buildkite/test-weekly.yml`) runs one step per model suite (trigger: `WEEKLY=1` or PR label `weekly-test`), for example:
-
-| Buildkite step | Test file | CI hardware |
-| -------------- | --------- | ----------- |
-| Reliability Test - qwen3-omni | `test_reliability_qwen3_omni.py` | H100 × 2 (`mithril-h100-pool`) |
-| Reliability Test - wan22 | `test_reliability_wan22.py` | H100 × 2 (`mithril-h100-pool`) |
-| Reliability Test - hunyuan-image | `test_reliability_hunyuan_image.py` | H100 × 4 (`mithril-h100-pool`) |
-| Reliability Test - voxcpm2 | `test_reliability_voxcpm2.py` | L4 × 1 (`gpu_1_queue`) |
-
-```bash
-pytest -s -v tests/dfx/reliability/test_reliability_qwen3_omni.py -m "slow"
-pytest -s -v tests/dfx/reliability/test_reliability_wan22.py -m "slow"
-pytest -s -v tests/dfx/reliability/test_reliability_hunyuan_image.py -m "slow"
-pytest -s -v tests/dfx/reliability/test_reliability_voxcpm2.py -m "slow"
-```
-
-#### Local commands
-
-```bash
-pytest --collect-only tests/dfx/reliability
-pytest -s -v tests/dfx/reliability/test_reliability_qwen3_omni.py -m slow
-pytest -s -v tests/dfx/reliability/test_reliability_wan22.py -m slow
-pytest -s -v tests/dfx/reliability/test_reliability_hunyuan_image.py -m slow
-pytest -s -v tests/dfx/reliability/test_reliability_voxcpm2.py -m slow
-```
-
-#### Adding a new model suite
-
-1. Add `test_reliability_<model>.py` under `tests/dfx/reliability/`.
-2. Define **`RELIABILITY_SCENARIOS`** and pass them through **`create_reliability_omni_server_params()`** with the correct deploy or e2e stage-config directory (same pattern as existing files).
-3. Reuse **`helpers`** for OOM / kill / raw HTTP; prefer **`assert_fault_exception()`** and **`resolve_oom_device_spec()`** from `tests/dfx/conftest.py` for consistent device selection vs stage YAML.
-4. Register **`slow`** (and **`hardware_test`** if needed); extend **`.buildkite/test-weekly.yml`** when the suite should run in weekly L5.

--   -   ***Stability***: `pytest -s -v tests/dfx/stability/scripts/test_stability_qwen3_omni.py` or `pytest -s -v tests/dfx/stability/scripts/test_stability_wan22.py` (or add `test_stability_<model>.py` alongside a matching JSON config)
-    -   ***Reliability***: `pytest -s -v tests/dfx/reliability/test_reliability_<model>.py -m slow` (current suites: `qwen3_omni`, `wan22`, `hunyuan_image`, `voxcpm2`; add `test_reliability_<suite>.py` and a matching step in `.buildkite/test-weekly.yml` for new models)

+# CI Settings
+
+This document describes **where** Buildkite YAML lives in the repo, **how each platform organizes CI**, and **how to add a new job**. It does not document agent queues, GPU types, or container plugin details—those belong in infra / preset files (for example `.buildkite/common/ci_mirror_hardwares.yml`).
+
+For CI levels (L1–L5) and triggers, see [Test System Overview](./test_system_overview.md). For test authoring, see [Test Writing Guide](./test_writing_guide.md). For running tests locally or replaying CI jobs, see [Test Execution Guide](./test_execution_guide.md).

+
+**Placement rules**
+
+| Rule | Detail |
+| ---- | ------ |
+| Platform code under platform dir | New CUDA jobs go in `.buildkite/cuda/`; do not add new top-level `.buildkite/test-*.yml` files. |
+| Shared logic in `common/` | Skip-ci and CUDA upload rendering stay in `.buildkite/common/scripts/`. |
+| Bootstrap vs test YAML | **Bootstrap** (`pipeline*.yml`) builds images and uploads **child** test pipelines. **Test** YAML (`test-*.yml`) lists pytest steps only. |
+| Register CI YAML in `skip_ci.py` | If you add a new whitelisted test pipeline file, update `L2_YAML_FILES`, `L3_YAML_FILES`, or `L45_YAML_FILES` in `.buildkite/common/scripts/skip_ci.py` so skip-ci paths stay correct. |
+
+There are still **legacy copies** at `.buildkite/*.yaml` (without the `cuda/` prefix). Treat `.buildkite/cuda/*` as source of truth.
+
+## Platform comparison
+
+| Platform | Bootstrap entry | Test job files | Upload mechanism | Job hardware in YAML |
+| -------- | ---------------- | -------------- | ---------------- | -------------------- |
+| **CUDA** | `cuda/pipeline.yml` | `test-ready.yml`, `test-merge.yml`, `test-nightly.yml`, `test-weekly.yml` | `upload_pipeline.py --upload` (expands uploader-only keys) | `mirror_hardwares: <preset>` (string) |
+| **NPU** | `npu/pipeline-npu.yml` | `test-npu-ready.yml`, `test-npu-nightly.yml` | `upload_pipeline.py --upload` | `mirror_hardwares: a2b3_npu_1` / `a2b3_npu_4` / `a3_npu_2` |
+| **AMD** | `amd/scripts/bootstrap-amd-omni.sh` | `test-amd-ready.yml`, `test-amd-merge.yml` | Jinja (`test-template-amd-omni.j2`) → `pipeline upload` | `agent_pool` + `mirror_hardwares: [amdproduction]` (array, template filter) |
+| **Intel** | `intel/scripts/bootstrap-intel-omni.sh` | `intel/pipeline-intel.yml` (steps inline) | Direct `pipeline upload` | Inline `agents.queue` on each step |
+
+## Platform configuration style
+
+=== "CUDA"
+
+    **Bootstrap:** [`cuda/pipeline.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/cuda/pipeline.yml) (hook upload) + [`cuda/bootstrap-upload-steps.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/cuda/bootstrap-upload-steps.yml) (child steps). Document 1 runs [`upload_pipeline.py --upload .buildkite/cuda/bootstrap-upload-steps.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/common/scripts/upload_pipeline.py), which injects `if` by step `key` from skip-ci and uploads image build plus L2–L5 child pipeline upload steps (see [Diff-aware CI — Bootstrap skip](#bootstrap-skip)).
+
+    **Test YAML:** `cuda/test-ready.yml` (L2), `test-merge.yml` (L3), `test-nightly.yml` (L4), `test-weekly.yml` (L5). Each file starts with shared `env:` then `steps:`.
+
+    | CI level | File | Typical trigger |
+    | -------- | ---- | ----------------- |
+    | L2 | `cuda/test-ready.yml` | `ready` label |
+    | L3 | `cuda/test-merge.yml` | `merge-test` label / main merge |
+    | L4 | `cuda/test-nightly.yml` | `nightly-test` label or `NIGHTLY=1` |
+    | L5 | `cuda/test-weekly.yml` | `weekly-test` label or `WEEKLY=1` |
+
+    **Upload:** `upload_pipeline.py --upload` expands uploader-only keys before Buildkite upload.
+
+    **Hardware in YAML:** `mirror_hardwares: <preset>` (string)—preset names in [`common/ci_mirror_hardwares.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/common/ci_mirror_hardwares.yml). Do **not** set `agents` / `plugins` on the same step.
+
+    **Conventions**
+
+    - **`depends_on`:** leaf jobs depend on `upload-ready-pipeline`, `upload-merge-pipeline`, etc.
+    - **`group` / `label`:** `:card_index_dividers:` groups; labels like `Diffusion · Qwen Image Test`.
+    - **`commands`:** `timeout … pytest …` with markers and `--run-level` for the pipeline level.
+    - **`source_file_dependencies`:** required on **E2E Test** leaf jobs in L2/L3; see [Step filtering](#step-filtering).
+
+    **Adding a job**
+
+    1. Pick the level file (ready / merge / nightly / weekly).
+    2. Add a step under the right **group** (usually **E2E Test** for model pytest).
+    3. Set `label`, `commands`, `mirror_hardwares`, `depends_on: upload-<level>-pipeline`.
+    4. For L2/L3 E2E, add `source_file_dependencies` (pytest + model + deploy YAML prefixes).
+    5. Dry-run:
+
+    ```bash
+    python3 .buildkite/common/scripts/upload_pipeline.py .buildkite/cuda/test-ready.yml
+    ```
+
+=== "NPU"
+
+    **Bootstrap:** [`npu/pipeline-npu.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/npu/pipeline-npu.yml) + [`npu/bootstrap-upload-steps.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/npu/bootstrap-upload-steps.yml)—same split as CUDA; builds A2/B3 and A3 CI images, then uploads child test pipelines.
+
+    **Test YAML:** `npu/test-npu-ready.yml` (L2), `test-npu-nightly.yml` (L4).
+
+    **Upload:** same as CUDA—`upload_pipeline.py --upload`.
+
+    **Hardware in YAML:** `mirror_hardwares` preset (string), expanded to `agents`, top-level `image`, and `plugins`. Presets: `a2b3_npu_1`, `a2b3_npu_4`, `a3_npu_2` in `common/ci_mirror_hardwares.yml`.
+
+    **Conventions**
+
+    - **`depends_on: upload-ready-pipeline`** (or `upload-nightly-pipeline`) ties jobs to bootstrap upload keys.
+    - Do not duplicate `agents` / `image` / `plugins` when using `mirror_hardwares`.
+
+    **Adding a job**
+
+    1. Edit `test-npu-ready.yml` (L2) or `test-npu-nightly.yml` (L4).
+    2. Add a step with `mirror_hardwares` (add a new preset in `ci_mirror_hardwares.yml` first if needed).
+    3. Set `commands` to your pytest file and markers.
+    4. Dry-run:
+
+    ```bash
+    python3 .buildkite/common/scripts/upload_pipeline.py .buildkite/npu/test-npu-ready.yml
+    ```
+
+    5. Register new pipeline paths in `skip_ci.py` (`L2_YAML_FILES` or `L45_YAML_FILES`) when applicable.
+
+=== "AMD"
+
+    **Bootstrap:** [`amd/scripts/bootstrap-amd-omni.sh`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/amd/scripts/bootstrap-amd-omni.sh)—skip-ci, diff filtering, Jinja render, then `buildkite-agent pipeline upload`.
+
+    **Test YAML (data):** `amd/test-amd-ready.yml` (L2 / PR), `test-amd-merge.yml` (L3 / main).
+
+    **Rendering:** [`test-template-amd-omni.j2`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/amd/test-template-amd-omni.j2) wraps data steps with `amd-build` image build and `amd_<agent_pool>` queues. Do **not** hand-edit generated `pipeline.yaml`.
+
+    **Hardware in YAML:** `agent_pool` (for example `mi325_1`) plus `mirror_hardwares: [amdproduction]` (array—Buildkite template filter, not the CUDA/NPU uploader preset mechanism).
+
+    **Data file fields**
+
+    | Field | Purpose |
+    | ----- | ------- |
+    | `agent_pool` | ROCm pool; template maps to `queue: amd_<pool>`. |
+    | `mirror_hardwares` | Which mirror HW runs the step (for example `[amdproduction]`). |
+    | `commands` | Passed into `run-amd-test.sh` via `TEST_COMMAND`. |
+
+    **Adding a job**
+
+    1. Edit `test-amd-ready.yml` or `test-amd-merge.yml`.
+    2. Copy a neighboring block: `label`, `agent_pool`, `mirror_hardwares`, `commands`, optional `grade`.
+    3. Regenerate via bootstrap / Jinja; update `skip_ci.py` if you add a new YAML path.
+
+=== "Intel"
+
+    **Bootstrap:** [`intel/scripts/bootstrap-intel-omni.sh`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/intel/scripts/bootstrap-intel-omni.sh)—skip-ci, then direct `pipeline upload`.
+
+    **Test YAML:** steps live inline in [`intel/pipeline-intel.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/intel/pipeline-intel.yml); runners under `intel/scripts/` (for example `run-xpu-test.sh`).
+
+    **Upload:** `buildkite-agent pipeline upload` (no `upload_pipeline.py` mirror expansion).
+
+    **Hardware in YAML:** inline `agents.queue` (for example `intel-gpu-omni`) on each step.
+
+    **Adding a job**
+
+    1. Add a step to `pipeline-intel.yml`, or extend an existing runner script.
+    2. Match `agents`, `env`, `timeout_in_minutes`, and `command`/`commands` with sibling steps.
+    3. Keep `pipeline-intel.yml` listed in `L2_YAML_FILES` in `skip_ci.py`.
+
+## Cross-cutting conventions
+
+### Diff-aware CI {#diff-aware-ci}
+
+PR diffs drive **two independent skip layers**. Both read changed files from git, but at different pipeline stages and with different granularity:
+
+| Layer | Script | When | What is skipped | Where you configure |
+| ----- | ------ | ---- | --------------- | ------------------- |
+| **Bootstrap** | [`skip_ci.py`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/common/scripts/skip_ci.py) + [`upload_pipeline.py`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/common/scripts/upload_pipeline.py) | Before child test pipelines upload (`cuda/pipeline.yml`, `npu/pipeline-npu.yml`, AMD/Intel bootstraps) | Entire default CI, or whole L2/L3 upload for a platform | Whitelists in `skip_ci.py`; bootstrap `if` injected by step `key` in `upload_pipeline.py` |
+| **Step filter** | [`upload_pipeline.py`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/common/scripts/upload_pipeline.py) | While uploading CUDA L2/L3 YAML | Individual Buildkite steps inside `test-ready.yml` / `test-merge.yml` | `source_file_dependencies` on each step or group |
+
+**Changed files** (both layers):
+
+| Build context | Diff command |
+| --- | --- |
+| Pull request | `git diff --name-only origin/<base>...<BUILDKITE_COMMIT>` |
+| `main` push | `git diff --name-only <commit>^..<commit>` |
+| Local dry-run / non-PR | Diff unavailable → bootstrap and step filter both keep all steps; uploader-only keys are still stripped |
+
+Label triggers (`ready`, `merge-test`) are unchanged—diff-aware logic only reduces what runs **after** a pipeline is already scheduled.
+
+#### Bootstrap skip {#bootstrap-skip}
+
+[`skip_ci.py`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/common/scripts/skip_ci.py) classifies the git diff into buckets (docs / qualifying skip-mark / whitelisted L2·L3·L4/L5 YAML / other), then picks one decision path. CUDA/NPU apply that decision by injecting Buildkite `if` on `bootstrap-upload-steps.yml` step keys; AMD/Intel call `gate_bootstrap_ci <platform> <l2|l3>`.
+
+##### Decision overview
+
+| Diff shape | Path | Default L2/L3 |
+| --- | --- | --- |
+| Product code / non-whitelisted paths | normal CI | all on |
+| Docs and/or qualifying skip-mark only | `skip_all` | all off (scheduled `main` NIGHTLY/WEEKLY exceptions below) |
+| Whitelisted CI YAML only | yaml-gated (`skip_l2_l3`) | per platform/level matrix |
+| Docs/skip-mark **+** whitelisted CI YAML | yaml-gated (`skip_l2_l3`) | same as CI-YAML-only (does **not** widen to normal CI) |
+| Non-qualifying skip-mark and no CI YAML | normal CI | all on |
+| Diff unavailable | normal CI | all on |
+
+**`skip_all` exceptions (CUDA/NPU bootstrap only):** PR labels (`nightly-test`, `merge-test`, `npu-test`, `weekly-test`, …) do **not** revive jobs. On `main`, scheduled `NIGHTLY=1` still builds the image and uploads L4 plus L2/L3 (with `--e2e`); `WEEKLY=1` still builds the image and uploads L5 (CUDA).
+
+**Yaml-gated nightly/weekly:** L4/L5 upload steps keep their normal label / `NIGHTLY` / `WEEKLY` conditions (for example PR `nightly-test` still uploads nightly). Only L2/L3 upload steps are matrix-gated.
+
+##### Whitelisted CI YAML → platform
+
+Register new files in `L2_YAML_FILES`, `L3_YAML_FILES`, or `L45_YAML_FILES` in `skip_ci.py`.
+
+| Level | File | Platform |

+| L4/L5 | `.buildkite/npu/test-npu-nightly.yml` | npu |
+
+##### Yaml-gated category branches
+
+`L2?` / `L3?` / `L45?` = whether any file in that whitelist changed. Untouched platforms/levels end up off.
+
+| ID | L2? | L3? | L45? | Enabled L2/L3 |
+| --- | --- | --- | --- | --- |
+| G1 | | | ✓ | none (all L2/L3 off) |
+| G2 | ✓ | | | L2 only on platforms whose L2 YAML changed |
+| G3 | | ✓ | | L3 only on platforms whose L3 YAML changed |
+| G4 | ✓ | ✓ | | union of G2 and G3 (same platform ready+merge → both on) |

+##### How platforms consume the decision
+
+| Platform | Mechanism |
+| --- | --- |
+| **CUDA** | `upload_pipeline.py` injects `if` by step `key` (`image-build`, `upload-ready-pipeline`, `upload-merge-pipeline`, …) from `is_run(cuda, l2/l3)` |
+| **NPU** | Same injection; no merge upload step (L3 always off in bootstrap) |
+| **AMD / Intel** | `gate_bootstrap_ci <platform> <l2\|l3>` exits 0 when `skip_all` or that target is off |
+
+Unit coverage: `tests/buildkite/test_skip_ci.py`.
+
+#### Step filtering {#step-filtering}
+
+CUDA **L2** (`.buildkite/cuda/test-ready.yml`) and **L3** (`.buildkite/cuda/test-merge.yml`) only. Bootstrap upload entry: `upload_pipeline.py --upload .buildkite/cuda/bootstrap-upload-steps.yml`.
+
+**Uploader-only keys** — removed before Buildkite sees the YAML; never used at runtime on agents:
+
+| Key | Purpose |
+| --- | ------- |
+| `source_file_dependencies` | List of path **prefixes**. If any changed file equals a prefix or starts with `prefix/`, keep the step (or group); otherwise omit it. |
+| `mirror_hardwares` | Expand to `agents` + `plugins` (+ optional `image`) from `ci_mirror_hardwares.yml`. |
+
+**Policy**
+
+- **Always uploaded** (no key): groups outside **E2E Test**—Simple Test, Diffusion unit tests, Engine/Model Executor, Distributed, Custom Pipeline, Entrypoints (L2), LoRA / Entrypoints (L3).
+- **Diff-gated**: every **E2E Test** leaf job. List the smallest prefix set per step—pytest file(s), model code under `vllm_omni/model_executor/models/` or `vllm_omni/diffusion/models/`, plus `stage_input_processors/` and `vllm_omni/deploy/*.yaml` when applicable. A **group** may define the key instead; the whole group drops if no prefix matches.
+
+**YAML examples**
+
+```yaml
+      - label: "Diffusion · Qwen Image Test"
+        source_file_dependencies:
+          - tests/e2e/online_serving/test_qwen_image.py

+        mirror_hardwares: h100_1
+
+      - label: "TTS · Qwen3-TTS CustomVoice Test"
+        source_file_dependencies:
+          - tests/e2e/online_serving/test_qwen3_tts_customvoice.py

+        commands:
+          - pytest -s -v tests/e2e/online_serving/test_qwen3_tts_customvoice.py ...
+        mirror_hardwares: l4_4
+```
+
+**Local dry-run**
+
+```bash
+python3 .buildkite/common/scripts/upload_pipeline.py .buildkite/cuda/test-ready.yml
+python3 .buildkite/common/scripts/upload_pipeline.py .buildkite/cuda/test-merge.yml | grep source_file_dependencies
+# (no output expected)
+```
+
+On PR builds, `upload_pipeline.py` logs `skip '…' (no changes under …)` for omitted steps.
+
+### Labels and grouping
+
+- Use **groups** for dashboard readability; keep **E2E Test** as the group name CUDA diff filtering expects for `--e2e` nightly runs on main.
+- Prefix labels by model domain: **Omni ·**, **TTS ·**, **Diffusion ·**, **Simple ·**, etc., matching existing steps.
+
+### Validation checklist
+
+| Check | Command / location |
+| ----- | ------------------ |
+| CUDA render | `python3 .buildkite/common/scripts/upload_pipeline.py .buildkite/cuda/test-<level>.yml` |
+| No leaked uploader keys | `… \| grep -E 'mirror_hardwares|source_file_dependencies'` → empty |
+| Skip-ci / upload unit tests | `pytest tests/buildkite/` |
+| Local job replay (CUDA L2+) | `tools/run_ready_jobs.sh`, `tools/run_merge_jobs.sh`, `tools/nightly/run_nightly_jobs.sh` (read YAML from `cuda/`) |

-When you want to add L4-level ***performance test*** cases, you can refer to the following format for case addition in `tests/dfx/perf/tests/test_qwen_omni.json`, `tests/dfx/perf/tests/test_tts.json`, or diffusion configs such as `tests/dfx/perf/tests/test_*_vllm_omni.json` (selected via `pytest ... run_benchmark.py --test-config-file <path>`):
+When you want to add L4-level ***performance test*** cases, add entries to JSON files under `tests/dfx/perf/tests/` and run them via `tests/dfx/perf/scripts/run_benchmark.py` (omni / TTS) or `run_diffusion_benchmark.py` (diffusion).

+**How runners pick cases**

+Without **`--test-config-file`**, each runner scans all `*.json` under `tests/dfx/perf/tests/` but only keeps its own model type:
+
+- **`run_benchmark.py`**: omni and TTS cases only (skips diffusion JSON).
+- **`run_diffusion_benchmark.py`**: diffusion cases only (skips omni / TTS JSON).
+
+Diffusion cases are detected when the JSON has `server_type` (typically `"vllm-omni"`) or `"diffusion"` in the `mark` array. Omni / TTS JSON has neither.
+
+**Running perf cases**
+
+Pass **`--test-config-file`** to run one JSON file as-is, or omit it for the bulk scan above and filter with pytest **`-m`** on each case's JSON `mark` (for example `pytest … run_benchmark.py -m "full_model and tts and H100"`).

+
+Optional top-level field on each perf JSON **case object** (one per `test_name`). `run_benchmark.py` and `run_diffusion_benchmark.py` read it via `tests.dfx.conftest.resolve_pytest_marks` and attach the marks to the corresponding `pytest.param`, so you can filter locally with `-m`.
+
+When `mark` is present, it must be an **array** with exactly one ``hardware_marks`` object (same shape as `@hardware_test` / `hardware_marks()` in `tests/helpers/mark.py`), followed by registered pytest marker name strings such as `full_model`, `omni`, `tts`, `diffusion`, or `local_model`.

+
+**Parametrization IDs**
+
+Each `(server, benchmark index)` pair becomes one `pytest.param` with id `{test_name}-{suffix}`. The suffix comes from `benchmark_params[].name` when set (for example `test_tts-p0`, `test_omni-p1`); otherwise it is derived from fields like `task` / `eval_phase`.
+
+**Benchmark result filenames**
+
+Result files use the **runtime** hardware label from `get_runtime_resource_label()` (detected GPU/NPU name on the machine that ran the job), **not** `mark.hardware_marks.res`. On the default H100 CI pool, `H100` is **omitted** from filenames (`resource_label_for_filename`).
+
+Examples:
+
+- Omni/TTS: `result_{test_name}_{optional_hw}_{dataset}_....json` under `BENCHMARK_DIR`
+- Diffusion: one aggregate `diffusion_result_{config_stem}_{optional_hw}_{timestamp}.json` per source JSON file (array of all runs from that file)
+
+**Local commands**

+```bash
+# Bulk load + filter by JSON mark

+## Setting Up the Test Environment
+### Creating a Container
+vLLM-Omni provides an official Docker image for deployment. These images are built upon vLLM Docker images and are available on [Docker Hub](https://hub.docker.com/r/vllm/vllm-omni/tags). The version of vLLM-Omni indicates which vLLM release it is based on.
+For a local test environment, you can follow the steps below to create a container:
+## Installing Dependencies
+### vLLM & vLLM-Omni
+vLLM-Omni is built based on vLLM. You can follow [install guide](../../getting_started/installation/README.md) to build your local environment.
+
+### Test Case Dependencies
+When running test cases, you may need to install the following dependencies:
+
+```bash
+uv pip install ".[dev]"
+apt-get install -y espeak-ng jq
+```
+
+## Running Tests
+Our test scripts use the pytest framework. First, please use `git clone https://github.com/vllm-project/vllm-omni.git` to download the vllm-omni source code. Then, in the root directory of vllm-omni, you can run the following commands in your local test environment to execute the corresponding test cases.

+[`tools/run_ready_jobs.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/run_ready_jobs.sh), [`tools/run_merge_jobs.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/run_merge_jobs.sh), and [`tools/nightly/run_nightly_jobs.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/nightly/run_nightly_jobs.sh) share the same run-time behavior (via [`tools/run_jobs_common.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/run_jobs_common.sh)):
+
+**Log layout** (default under `logs/ready_jobs`, `logs/merge_jobs`, or `logs/nightly_jobs`; override with `--log-dir`):
+
+| Path | Description |
+|------|-------------|
+| `jobs/*.sh` | Generated per-step bash wrappers |
+| `jobs/.job_timeouts` | Job key → `timeout_in_minutes` from Buildkite YAML (when set) |
+| `<job_key>.log` | Tee output for each job |
+| `timing_summary.log` | Per-job duration and total wall time after the run completes |
+
+**Timing:** while each job runs, stderr prints `finished in …` or `failed after …`. When all jobs finish, a summary is printed and written to `timing_summary.log`, for example:
+
+```
+=== Job timing summary ===
+  TTS_VoxCPM2_Test  25m 40s  OK
+  Omni_Qwen3-Omni_Test  8m 05s  TIMED OUT
+Total wall time: 33m 45s (2 jobs)
+Failed jobs: 1/2
+```
+
+**Timeouts:** if a Buildkite step defines `timeout_in_minutes`, the runner wraps that job with `timeout ${N}m` (aligned with CI). Steps without `timeout_in_minutes` rely on any inline `timeout …` already present in the extracted pytest command. On timeout the process exits with code `124` and the summary marks the job as `TIMED OUT`.
+
+=== "L1 level"
+
+    ```bash
+    cd tests
+    pytest -s -v -m "core_model and cpu"
+    ```
+    The latest test command is available in the "Simple Unit Test" step of this [pipeline](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/cuda/test-ready.yml).
+
+=== "L2 level"
+
+    **Recommended:** run CI-aligned jobs from the repo root via [`tools/run_ready_jobs.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/run_ready_jobs.sh). The script reads [`.buildkite/cuda/test-ready.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/cuda/test-ready.yml), generates per-step bash wrappers, runs pytest, and tees logs under `logs/ready_jobs/` (see [CI job runners](#ci-job-runners-l2l4-logs-timing-and-timeouts) for timing and timeout behavior). Requires `bash`, `python3`, and PyYAML (`pip install pyyaml`).
+
+    ```bash
+    # All L2 and L1 jobs (default: every pytest step in test-ready.yml)
+    bash tools/run_ready_jobs.sh
+
+    # Skip L1-style "Simple Test" steps in test-ready.yml (group or "Simple ·" labels)
+    bash tools/run_ready_jobs.sh --skip-simple
+    bash tools/run_ready_jobs.sh --skip-simple --model-type diffusion
+
+    # Preview extracted commands without running
+    bash tools/run_ready_jobs.sh --dry-run
+
+    # Filter by model area (OR semantics): omni | tts | diffusion | all
+    bash tools/run_ready_jobs.sh --model-type omni
+    bash tools/run_ready_jobs.sh --model-type tts,diffusion
+
+    # Match a Buildkite label substring (e.g. one model suite)
+    bash tools/run_ready_jobs.sh --model-type tts --label-substr "VoxCPM2"
+
+    ```
+
+    **Ad hoc:** run a single test file or marker expression manually:
+
+    ```bash
+    cd tests
+    pytest -s -v test_xxxx.py --run-level=core_model
+    pytest -s -v -m "core_model and distributed_cuda and L4" --run-level=core_model
+    ```
+
+=== "L3 level"
+
+    **Recommended:** run CI-aligned jobs from the repo root via [`tools/run_merge_jobs.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/run_merge_jobs.sh). The script reads [`.buildkite/cuda/test-merge.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/cuda/test-merge.yml), generates per-step bash wrappers, runs pytest, and tees logs under `logs/merge_jobs/` (see [CI job runners](#ci-job-runners-l2l4-logs-timing-and-timeouts)). Requires `bash`, `python3`, and PyYAML (`pip install pyyaml`).
+
+    ```bash
+    # All L3 and L1 jobs (default: every pytest step in test-merge.yml)
+    bash tools/run_merge_jobs.sh
+
+    # Skip L1-style "Simple Test" steps in test-merge.yml (group or "Simple ·" labels)
+    bash tools/run_merge_jobs.sh --skip-simple
+    bash tools/run_merge_jobs.sh --skip-simple --model-type omni
+
+    # Preview extracted commands without running
+    bash tools/run_merge_jobs.sh --dry-run
+
+    # Filter by model area (OR semantics): omni | tts | diffusion | all
+    bash tools/run_merge_jobs.sh --model-type diffusion
+    bash tools/run_merge_jobs.sh --model-type omni,tts
+
+    # Match a Buildkite label substring
+    bash tools/run_merge_jobs.sh --model-type diffusion --label-substr "Wan22"
+
+    ```
+
+    **Ad hoc:** run a single test file or marker expression manually:
+
+    ```bash
+    pytest -s -v test_xxxx.py --run-level=advanced_model
+    pytest -s -v -m "advanced_model and distributed_cuda and L4" --run-level=advanced_model
+    ```
+
+
+=== "L4 level"
+
+    **Recommended:** run CI-aligned nightly jobs from the repo root via [`tools/nightly/run_nightly_jobs.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/nightly/run_nightly_jobs.sh). The script reads [`.buildkite/cuda/test-nightly.yml`](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/cuda/test-nightly.yml), generates per-step bash wrappers, runs pytest (perf jobs first, then aggregates perf JSON into Excel), and tees logs under `logs/nightly_jobs/` (see [CI job runners](#ci-job-runners-l2l4-logs-timing-and-timeouts); `generate_nightly_perf_excel` is included in the timing summary). Requires `bash`, `python3`, and PyYAML (`pip install pyyaml`).
+
+    ```bash
+    # All nightly jobs (default: test-type all, model-type all)
+    bash tools/nightly/run_nightly_jobs.sh
+
+    # Preview extracted commands without running
+    bash tools/nightly/run_nightly_jobs.sh --dry-run
+
+    # Test kind (--test-type, OR semantics): perf | acc | function | stability | local | all
+    bash tools/nightly/run_nightly_jobs.sh --test-type function
+    bash tools/nightly/run_nightly_jobs.sh --test-type perf,acc
+
+    # Model area (--model-type, OR semantics): omni | tts | diffusion | all
+    bash tools/nightly/run_nightly_jobs.sh --test-type function --model-type omni
+    bash tools/nightly/run_nightly_jobs.sh --test-type perf --model-type diffusion
+
+    # Stability scripts (tests/dfx/stability/scripts/) and local marker tests
+    bash tools/nightly/run_nightly_jobs.sh --test-type stability --model-type omni
+    bash tools/nightly/run_nightly_jobs.sh --test-type local --model-type tts
+    ```
+
+    Perf steps (label contains ``Perf Test``) run before other jobs; Excel output is written under ``logs/``. Diffusion nightly steps may also appear in [test-nightly-diffusion.yml](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/test-nightly-diffusion.yml) on CI.
+
+    **Ad hoc:** run a single test file or marker expression manually:
+
+    ```bash
+    cd tests
+    pytest -s -v test_xxxx.py --run-level=full_model
+    pytest -s -v -m "full_model and distributed_cuda and L4" --run-level=full_model
+    pytest -s -v -m "full_model and (omni or tts) and H100" --run-level=full_model
+    ```
+    If you only want to run specific test cases on a particular platform, you can use:
+    ```bash
+    pytest -s -v -m "full_model and distributed_cuda and L4"  --run-level=full_model
+    ```
+    Note: ``run_benchmark.py`` and ``run_diffusion_benchmark.py`` accept an optional ``--test-config-file``. If omitted, each loads every ``*.json`` under ``tests/dfx/perf/tests/`` (omni/tts vs diffusion split by ``is_diffusion_perf_config``) and pytest ``-m`` filters by each case's JSON ``mark``:
+    ```bash
+    pytest -sv tests/dfx/perf/scripts/run_benchmark.py -m "full_model and tts and H100"
+    pytest -sv tests/dfx/perf/scripts/run_diffusion_benchmark.py -m "full_model and diffusion and H100"
+    pytest -sv tests/dfx/perf/scripts/run_benchmark.py --test-config-file tests/dfx/perf/tests/test_tts.json
+    pytest -sv tests/dfx/perf/scripts/run_diffusion_benchmark.py --test-config-file tests/dfx/perf/tests/test_cosmos3_vllm_omni.json
+    ```
+    Nightly **Perf Test** jobs in ``test-nightly.yml`` use ``--test-config-file`` only (no ``-m``). E2e L4 function tests still use ``full_model`` + ``--run-level full_model`` (see [test-nightly.yml](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/test-nightly.yml)). Example:
+
+=== "L5 level"
+
+    L5 includes stability and reliability testing. Typical commands:
+
+    ```bash
+    cd tests
+
+    # Stability: Qwen3-Omni
+    pytest -s -v dfx/stability/scripts/test_stability_qwen3_omni.py -m slow
+
+    # Stability: Wan2.2 (v1/videos diffusion benchmark loop)
+    pytest -s -v dfx/stability/scripts/test_stability_wan22.py -m slow
+
+    # Reliability: Qwen3-Omni (H100 × 2)
+    pytest -s -v dfx/reliability/test_reliability_qwen3_omni.py -m slow
+
+    # Reliability: Wan2.2 (H100)
+    pytest -s -v dfx/reliability/test_reliability_wan22.py -m slow
+
+    # Reliability: HunyuanImage DiT (H100 × 4)
+    pytest -s -v dfx/reliability/test_reliability_hunyuan_image.py -m slow
+
+    # Reliability: VoxCPM2 (L4)
+    pytest -s -v dfx/reliability/test_reliability_voxcpm2.py -m slow
+
+    ```
+
+    The latest L5 CI jobs (reliability + invalid-parameter weekly steps) are in [test-weekly.yml](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/cuda/test-weekly.yml).

-# Test Guide
-## Setting Up the Test Environment
-### Creating a Container
-vLLM-Omni provides an official Docker image for deployment. These images are built upon vLLM Docker images and are available on [Docker Hub](https://hub.docker.com/r/vllm/vllm-omni/tags). The version of vLLM-Omni indicates which vLLM release it is based on.
-For a local test environment, you can follow the steps below to create a container:
-## Installing Dependencies
-### vLLM & vLLM-Omni
-vLLM-Omni is built based on vLLM. You can follow [install guide](../../getting_started/installation/README.md) to build your local environment.
-
-### Test Case Dependencies
-When running test cases, you may need to install the following dependencies:
-
-```bash
-uv pip install ".[dev]"
-apt-get install -y ffmpeg
-```
-
-## Running Tests
-Our test scripts use the pytest framework. First, please use `git clone https://github.com/vllm-project/vllm-omni.git` to download the vllm-omni source code. Then, in the root directory of vllm-omni, you can run the following commands in your local test environment to execute the corresponding test cases.
-
-=== "L1 level"
-
-    ```bash
-    cd tests
-    pytest -s -v -m "core_model and cpu"
-    ```
-    The latest test command is available in the "Simple Unit Test" step of this [pipeline](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/test-ready.yml).
-
-=== "L2 level"
-
-    ```bash
-    cd tests
-    pytest -s -v -m "core_model and not cpu" --run-level=core_model
-    ```
-    If you only want to run a specific test case, you can use:
-    ```bash
-    pytest -s -v test_xxxx.py --run-level=core_model
-    ```
-    If you only want to run specific test cases on a particular platform, you can use:
-    ```bash
-    pytest -s -v -m "core_model and distributed_cuda and L4"  --run-level=core_model
-    ```
-    The latest test commands for various test suites can be found in the [pipeline](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/test-ready.yml).
-
-=== "L3 level"
-
-    ```bash
-    pytest -s -v -m "advanced_model" --run-level=advanced_model
-    ```
-    If you only want to run a specific test case, you can use:
-    ```bash
-    pytest -s -v test_xxxx.py --run-level=advanced_model
-    ```
-    If you only want to run specific test cases on a particular platform, you can use:
-    ```bash
-    pytest -s -v -m "advanced_model and distributed_cuda and L4"  --run-level=advanced_model
-    ```
-    The latest L3 test commands for various test suites can be found in the [pipeline](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/test-merge.yml).
-
-
-=== "L4 level"
-
-    ```bash
-    cd tests
-    pytest -s -v -m "full_model" --run-level=full_model
-    ```

-    ```bash
-    pytest -s -v -m "full_model and distributed_cuda and L4"  --run-level=full_model
-    ```
-    Note: To run performance tests (defaults to ``test_qwen_omni.json``; use ``--test-config-file tests/dfx/perf/tests/test_tts.json`` for TTS):
-    ```bash
-    pytest -s -v tests/dfx/perf/scripts/run_benchmark.py
-    ```
-    The latest L4 (nightly) test commands use the `full_model` marker and `--run-level full_model` (see [test-nightly.yml](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/test-nightly.yml) and [test-nightly-diffusion.yml](https://github.com/vllm-project/vllm-omni/blob/main/.buildkite/test-nightly-diffusion.yml)). Example:
