"[CI/Build][NPU] Run HunyuanVideo-1.5 perf step via run_benchmark.py", + "body": "## Purpose\n\nFixes #8074.\n\nThe NPU nightly step **Diffusion X2V · HunyuanVideo-1.5 Perf Test** failed with pytest exit 5 (`collected 1 item / 1 deselected / 0 selected`). PR #7737 migrated `tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json` from the diffusion schema (`benchmark_params[].dataset`) to the omni-bench schema (`benchmark_params[].dataset_name`) and switched the CUDA nightly HunyuanVideo-1.5 step and the NPU Wan 2.2 step to `run_benchmark.py`, but missed this NPU step. It still invoked `run_diffusion_benchmark.py`, whose schema-based `is_diffusion_perf_config` filter (it does not look at the `mark` field) skipped both cases as omni-bench generation cases, so pytest selected 0 tests and Buildkite treated the empty selection as a failure.\n\n## Changes\n\n- `.buildkite/npu/test-npu-nightly.yml`: run the HunyuanVideo-1.5 perf step via `run_benchmark.py` with `BENCHMARK_DIR` and `tests/dfx/perf/results/*.json` artifact upload — same shape as the already-migrated NPU Wan 2.2 step and the fixed CUDA HunyuanVideo-1.5 step.\n- `tests/dfx/perf/tests/test_runner_metadata.py`: add `test_buildkite_perf_steps_use_matching_runner_schema`, which scans every `.buildkite` pipeline and asserts each perf JSON referenced via `--test-config-file` is run by the runner matching its schema (`run_diffusion_benchmark.py` ⇔ `dataset`, `run_benchmark.py` ⇔ `dataset_name`), and pins the issue's JSON to the omni runner. This catches the step/JSON mismatch class from #8074 (mixed-schema JSONs, which either runner would silently truncate, are flagged too).\n\n## Test Plan\n\n**vLLM Version:** N/A (CI config + tests only)\n\n**vLLM-Omni Commit:** 98e123f3e0531c5c2d1a74ad1791831ad3ca6e02\n\n- [x] Regression-test scan passes over all 33 runner invocations across `.buildkite` pipelines (0 mismatches)\n- [x] Reproduced the failure mechanism: the old runner selects 0 cases for this JSON; the new runner loads both cases and the step's `-m \"npu and A3\"` filter still selects the A3 case (`test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2`)\n- [x] `check-forbidden-imports` pre-commit hook passes on the changed test file\n- [x] The NPU pipeline renders through the official `_render_test_pipeline` path and the fixed step has the expected commands (full Buildkite jsonschema validation runs in CI)\n\n## Test Result\n\nVerified on Ascend A2 (container `zc-vllm-omni-dev`):\n\n```\n[1] pipeline scan: 33 invocations, 0 mismatches\n[2] issue-file pin OK: hunyuanvideo15_t2v is omni-bench schema\n[3a] run_diffusion_benchmark with issue JSON: 0 case(s) selected (issue state)\n[3b] run_benchmark with issue JSON: 2 case(s) loaded\n test_hunyuanvideo15_t2v_single_device: -m 'npu and A3' selectable = False\n test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2: -m 'npu and A3' selectable = True\n```\n\nNote: the A2 container's vLLM (0.28-era) predates the vLLM 0.30.0 rebase on main, so pytest cannot start there for any test (`ImportError: cannot import name 'KVConnectorBlockState'`); the verifications above were ", + "changed_files": [ + ".buildkite/npu/test-npu-nightly.yml", + "tests/dfx/perf/tests/test_runner_metadata.py" + ], + "diff_excerpt": "--- .buildkite/npu/test-npu-nightly.yml\n@@ -313,13 +313,12 @@ steps:\n HF_HUB_OFFLINE: \"1\"\n DIFFUSION_ATTENTION_BACKEND: TORCH_SDPA\n commands:\n- - export DIFFUSION_BENCHMARK_DIR=tests/dfx/perf/results\n+ - export BENCHMARK_DIR=tests/dfx/perf/results\n - |\n set +e\n- pytest -s -v tests/dfx/perf/scripts/run_diffusion_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n+ pytest -s -v tests/dfx/perf/scripts/run_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n EXIT=$$?\n- buildkite-agent artifact upload \"tests/dfx/perf/results/diffusion_result_*.json\"\n- buildkite-agent artifact upload \"tests/dfx/perf/results/logs/*.log\"\n+ buildkite-agent artifact upload \"tests/dfx/perf/results/*.json\"\n exit $$EXIT\n - label: \":full_moon: Diffusion X2V · Wan 2.2 Function Test\"\n source_file_dependencies: diffusion_wan22_function\n--- tests/dfx/perf/tests/test_runner_metadata.py\n@@ -235,6 +235,53 @@ def test_is_diffusion_perf_config():\n assert is_diffusion_perf_config(custom_edits_cfg)\n \n \n+def test_buildkite_perf_steps_use_matching_runner_schema():\n+ \"\"\"Every Buildkite step must run a perf JSON with the runner matching its schema.\n+\n+ Regression for #8074: the NPU nightly HunyuanVideo-1.5 step kept invoking\n+ ``run_diffusion_benchmark.py`` after the JSON was migrated to the omni-bench\n+ schema (#7737).

run_benchmark.py", + "body": "## Purpose\n\nFixes #8074.\n\nThe NPU nightly step **Diffusion X2V · HunyuanVideo-1.5 Perf Test** failed with pytest exit 5 (`collected 1 item / 1 deselected / 0 selected`). PR #7737 migrated `tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json` from the diffusion schema (`benchmark_params[].dataset`) to the omni-bench schema (`benchmark_params[].dataset_name`) and switched the CUDA nightly HunyuanVideo-1.5 step and the NPU Wan 2.2 step to `run_benchmark.py`, but missed this NPU step. It still invoked `run_diffusion_benchmark.py`, whose schema-based `is_diffusion_perf_config` filter (it does not look at the `mark` field) skipped both cases as omni-bench generation cases, so pytest selected 0 tests and Buildkite treated the empty selection as a failure.\n\n## Changes\n\n- `.buildkite/npu/test-npu-nightly.yml`: run the HunyuanVideo-1.5 perf step via `run_benchmark.py` with `BENCHMARK_DIR` and `tests/dfx/perf/results/*.json` artifact upload — same shape as the already-migrated NPU Wan 2.2 step and the fixed CUDA HunyuanVideo-1.5 step.\n- `tests/dfx/perf/tests/test_runner_metadata.py`: add `test_buildkite_perf_steps_use_matching_runner_schema`, which scans every `.buildkite` pipeline and asserts each perf JSON referenced via `--test-config-file` is run by the runner matching its schema (`run_diffusion_benchmark.py` ⇔ `dataset`, `run_benchmark.py` ⇔ `dataset_name`), and pins the issue's JSON to the omni runner. This catches the step/JSON mismatch class from #8074 (mixed-schema JSONs, which either runner would silently truncate, are flagged too).\n\n## Test Plan\n\n**vLLM Version:** N/A (CI config + tests only)\n\n**vLLM-Omni Commit:** 98e123f3e0531c5c2d1a74ad1791831ad3ca6e02\n\n- [x] Regression-test scan passes over all 33 runner invocations across `.buildkite` pipelines (0 mismatches)\n- [x] Reproduced the failure mechanism: the old runner selects 0 cases for this JSON; the new runner loads both cases and the step's `-m \"npu and A3\"` filter still selects the A3 case (`test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2`)\n- [x] `check-forbidden-imports` pre-commit hook passes on the changed test file\n- [x] The NPU pipeline renders through the official `_render_test_pipeline` path and the fixed step has the expected commands (full Buildkite jsonschema validation runs in CI)\n\n## Test Result\n\nVerified on Ascend A2 (container `zc-vllm-omni-dev`):\n\n```\n[1] pipeline scan: 33 invocations, 0 mismatches\n[2] issue-file pin OK: hunyuanvideo15_t2v is omni-bench schema\n[3a] run_diffusion_benchmark with issue JSON: 0 case(s) selected (issue state)\n[3b] run_benchmark with issue JSON: 2 case(s) loaded\n test_hunyuanvideo15_t2v_single_device: -m 'npu and A3' selectable = False\n test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2: -m 'npu and A3' selectable = True\n```\n\nNote: the A2 container's vLLM (0.28-era) predates the vLLM 0.30.0 rebase on main, so pytest cannot start there for any test (`ImportError: cannot import name 'KVConnectorBlockState'`); the verifications above were ", + "changed_files": [ + ".buildkite/npu/test-npu-nightly.yml", + "tests/dfx/perf/tests/test_runner_metadata.py" + ], + "diff_excerpt": "--- .buildkite/npu/test-npu-nightly.yml\n@@ -313,13 +313,12 @@ steps:\n HF_HUB_OFFLINE: \"1\"\n DIFFUSION_ATTENTION_BACKEND: TORCH_SDPA\n commands:\n- - export DIFFUSION_BENCHMARK_DIR=tests/dfx/perf/results\n+ - export BENCHMARK_DIR=tests/dfx/perf/results\n - |\n set +e\n- pytest -s -v tests/dfx/perf/scripts/run_diffusion_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n+ pytest -s -v tests/dfx/perf/scripts/run_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n EXIT=$$?\n- buildkite-agent artifact upload \"tests/dfx/perf/results/diffusion_result_*.json\"\n- buildkite-agent artifact upload \"tests/dfx/perf/results/logs/*.log\"\n+ buildkite-agent artifact upload \"tests/dfx/perf/results/*.json\"\n exit $$EXIT\n - label: \":full_moon: Diffusion X2V · Wan 2.2 Function Test\"\n source_file_dependencies: diffusion_wan22_function\n--- tests/dfx/perf/tests/test_runner_metadata.py\n@@ -235,6 +235,53 @@ def test_is_diffusion_perf_config():\n assert is_diffusion_perf_config(custom_edits_cfg)\n \n \n+def test_buildkite_perf_steps_use_matching_runner_schema():\n+ \"\"\"Every Buildkite step must run a perf JSON with the runner matching its schema.\n+\n+ Regression for #8074: the NPU nightly HunyuanVideo-1.5 step kept invoking\n+ ``run_diffusion_benchmark.py`` after the JSON was migrated to the omni-bench\n+ schema (#7737).

lane。\n- 强制：H3 online FP8 与 layerwise offload 当前标为 incompatible；resident FP8 可与 TP、VAE\n tiling 组合。BF16/FP8 A/B 使用同一 immutable checkpoint、prompt、seed、size、frames、\n steps、输入合同与并行/资源设置；T2VA case 即使显式给出 width/height，也必须在\n `sampling_params.extra_args` 带合法 named `aspect_ratio`。joint output 同时检查 video LPIPS\n 和 32 kHz audio 的 spectral cosine/RMS ratio。PSNR、MAE 与 peak memory 是 report-only\n 指标，不能冒充 gate。\n- 禁止：只验视频就宣称 H3 joint-output quality；把一次 22% memory observation 写成稳定\n 上界；让 FP8+layerwise offload 到 Cutlass kernel 才因 flattened-weight stride 失败。\n- 验收：当前 2x H100 case 的 gates 是 LPIPS <= 0.20、audio spectral cosine >= 0.80、\n RMS ratio 在 0.50–2.00，且 sample rate 为 32000；单测还要证明 phase-tolerant metric\n 接受相移但拒绝 spectral drift。质量 test 的 T2VA `aspect_ratio=\"16:9\"` 是同一 case 的\n 必填输入，不是量化变量；输入合同演进后应修正 fixture，不能靠跳过 case 或放宽质量 gate\n 恢复 CI。^[PR #5737] ^[PR #5829]\n\n## MMH3-1c — H3 fused norm/RoPE 必须保持 checkpoint dtype 与 partial-rotation 布局\n\n- 触发：修改 H3 q/k norm、RoPE frequency packing、head dim 或 shared fused-layer dispatch。\n- 强制：H3 使用共享 `RMSNorm`，gamma 保持 BF16，而 native reduction/scale 在 FP32 累加后\n cast 回输入 dtype。CUDA/HIP eager 尝试 fused RMSNorm、异常时回退 native，compile tracing\n 直接 native；MUSA 独立走 `F.rms_norm` 以保留 dynamic Inductor 可融合 graph；XPU 走 native，\n NPU 直接调用 `npu_rms_norm` 且没有该\n fallback。RoPE 使用 NeoX `RotaryEmbedding(half_head_dim=False)`：128 维 head 只旋转前 96 维\n 并原样保留末 32 维；CUDA/HIP/native 把 H3 的 tiled full frequencies 转为 half kernel layout，\n XPU 走 native；MUSA 对这个 full-dim、非 interleaved NeoX case 走 inline full-frequency 公式，\n 其他 layout 回 native；MindIE 接收 full layout。H3 `_apply_rope` 的 q/k 是 3D `[S,H,D]`；\n MindIE-SD kernel 只收 4D，因此 shared adapter 必须临时变为 `[1,S,H,D]` 并把输出恢复到 3D。\n- 强制：H3 旋转宽度从 config 静态派生为 `rot_dim = 6 * rope_inv_freq_len`，默认 16 得到 96，\n 不再在 forward 从 `freqs.shape[-1]` 读取动态 symbol。这样 compile 保持静态 slice，但 caller 仍\n 只调用 shared `RotaryEmbedding`、不含平台分支；config 与 frequency producer 不一致必须由 parity\n test 暴露，不能静默旋转另一宽度。^[PR #5881]\n- 禁止：把任意 96 维随机 frequency 当成 H3 producer 合同；合法 full layout 是同一 48 维\n half 的拼接。也不能从 CPU/reference 与 mocked NPU/MindIE wiring 推断真实 fused-kernel parity。\n PR #5896 的新增 mock 只断言 MindIE 收到 4D、输出恢复 3D 且 identity 回传不变；没有执行真实\n rotary 数学，也没有新增原生 4D control。\n- 验收：以 `cat([half, half])` frequency 对照 native reference，逐值断言 96 维旋转和 32 维\n passthrough；另测 BF16 gamma/FP32 accumulation、compile native path 与各平台参数 wiring。\n 真实 kernel 性能与数值结论需目标硬件复测；PR 报告的 491014→475070 ms 来自非目标\n `5215e03a` 且缺硬件与重复次数，只能作为有界外部观察，不能写成稳定 3.35% 保证。PR #5896\n body 报告 8×Ascend

QKV、S=96000、7 local heads、head_dim 128/rot_dim 96、\n `torch.compile(fullgraph=True,dynamic=True)`，5 warmups、2 discarded pilots、20 个带 512 MiB\n cache flush 的交错样本。该 exact Q/K RMSNorm+RoPE region 的 event median\n 30.0062→1.6323 ms（18.38×），同步 wall 30.0695→1.6893 ms（17.80×）；不是 TP8、端到端\n request、其他 shape/dtype/layout 或其他 MUSA SKU 的保证。finite/shape/BF16 gate 与 direct-inline\n 接近只覆盖该 A/B，且未给 correctness tolerance/reference、benchmark script 或 raw artifact；\n 当前自动测试没有 MUSA dispatch/parity，CPU reference 只验证 96 维旋转和 32 维\n passthrough。^[PR #5881]\n\n## MMH3-1e — H3 TRTLLM 必须以兼容性、packed 合同和 role 隔离决定 dense/opt-in 路径\n\n- 触发：修改 H3 的 TRTLLM default、packed `cu_seqlens`/mask、SAGE、Skip-Softmax、\n `minimax_h3.token_refiner` role 或 denoise timestep context。\n- 强制：仅兼容 datacenter Blackwell SM100/103、`head_dim=128`、有 FlashInfer trtllm-gen capability\n 且模型声明 packed 或 mask-free path 时，H3 才自动选 dense BF16 `TRTLLM_ATTN`。workstation\n Blackwell、缺依赖、错误 geometry 或需要 mask 的路径必须走平台 fallback；显式不兼容选择必须启动\n 失败。SAGE 与 Skip-Softmax 都是默认关闭的有损 opt-in。\n- 强制：TRTLLM 只允许无 SP 或 pure Ulysses；Ring 与 `skip_softmax` 组合报错、Ring 的 `quant`\n 不生效，AllGather-KV 在选择时拒绝。main DiT 与 token refiner 必须是独立 role；`per_role` 的\n `AttentionSpec` 替换整个 default spec，故 token refiner 要显式只配 dense backend，不能继承 SAGE\n 或 Skip-Softmax。H3 checkpoint 没有 calibration metadata，recipe 应使用 direct\n `threshold=0.05`，而非 `target_sparsity`。\n- 强制：单请求 producer-owned `[real,pad]` metadata 必须完整、Python host length 与同-device\n `int32` canonical cu views 一致且在 bounds；TRTLLM 裁 suffix 后恢复零输出，任何 nonempty\n `attn_mask` fail closed。generic complete cu_seqlens 保留真实 multi-document ragged path，尾部空\n pair 折叠；不可把两种合同互换。短于 SAGE `k_block_size` 的实 KV 保持 dense，不得因 token refiner\n 关闭 main DiT。\n- 禁止：把 packed shortcut 泛化为 arbitrary mask、multi-request layout 或第三方 metadata；让 padding\n 进入 SAGE quantization；将 docs-only PR #6724 当作 runtime、质量或性能证明。\n- 验收：覆盖 default/fallback/explicit-incompatible matrix、pure-Ulysses/Ring/AllGather admission、\n whole-spec `per_role` replacement 和 H3 direct-threshold recipe；并保留 packed trim/zero restore、\n malformed metadata、ragged/empty terminal、mask rejection和 short-role dense regression。^[PR #6542] ^[PR #6724]\n\n## MMH3-1g — H3 NPU mask-free opt-in 必须保留 Ring 与 malformed-metadata fallback\n\n- 触发：修改 H3 `_run_packed_attention`、NPU Flash backend capability、packed padding 或\n LaserAttention scale。\n- 强制：H3 在非 Ring 时可因 backend 的 prefix slicing 或 packed-mask-free capability 不构造 mask，\n 并发布四个 cu/max key、`valid_kv_length`、`npu_attn_varlen=True` 和\n `laser_input_scale=256.0`。Ring 必须令 opt-in false 并保留 padding mask，因为 aligned rows 是固定\n P2P buffer 合同；CUDA packed varlen/cuDNN prefix slicing 继续走各自 capability，H3 caller 不按\n platform 分支。shared NPU resolver/fallback 细节见 DIFF-1g。\n- 禁止：让 capability method 变成 duck-typed backend 的硬依赖却不更新 doubles/plugins；不能把\n H3 的 `[real,pad]` contract 泛化为 ragged multi-document。Laser 的 256 缩放只针对报告的 fp16\n workspace overflow，其他 backend 忽略；online KV quant path不经过本优化。repo 内 TeaCache\n `FakeBackend` 现已实现 capability 并返回 false，所以 extractor tests 保持 abstract-default 的\n masked path；这不等于 production consumer 已有 default-safe access。第三方 duck-typed backend\n 仍必须继承 base 或实现该 classmethod，并对 registry override 做 capability census。\n- 验收：model contract tests 分别覆盖 prefix-slice、packed-mask-free、普通 backend 与 Ring；backend\n tests 再覆盖 malformed fallback 和 Laser math。真实 Ascend parity/内存/延迟证据不能由 CPU mock\n 替代；同 seed E2E output comparison 与重新抓 memory snapshot 在 PR 中仍列为 follow-up。\n ^[PR #5891] ^[PR #5997]\n\n## MMH3-1h — H3 必须预构造 packed RoPE table 并让缓存提取器复用\n\n- 触发：修改 MiniMax H3 的 `MiniMaxH3Rope`、`MiniMaxH3Attention`、SP prepare、TeaCache extractor 或 q/k fused 调用。\n- 强制：H3 先将 `MiniMaxH3Rope` 的 tiled frequency 输出交给 `_build_rope_table`，只从其前半段构造 cos/sin 并生成 BF16 packed table；该 table 必须在完整 packed sequence 上构造一次，经 `sp_prepare` 原样传给所有 DiT blocks 和 attention，TeaCache extractor 复用同一 helper。`rope_table=None` 的 token-refiner 路径继续只做 q/k RMSNorm；H3 的 128 维 head 只旋转前 96 维并保留后 32 维。共享算子边界以 [DIFF-1l](../../components/diffusion/rules.md#diff-1l-fused-qk-rmsnorm-与-packed-rope-必须共享布局并保留-eager-fallback) 为准。\n- 禁止：把 H3 已复制的第二个 frequency half 当成独立 sin 输入，向 fused API 传 raw `rope_freqs`，或在每个 block、SP 分支和 TeaCache extractor 内重建不同 table；也不能把 token-refiner 的无 RoPE 路径误接到 fused table 调用。\n- 验收：模型合同测试须断言完整 sequence 的 table shape 与 `[cos, sin]` 数值、SP 透传 identity、DiT q/k 的 96/128 partial rotation 和 32 维 tail preservation，并覆盖 TeaCache extractor 与 `rope_table=None` 分支。当前 PR 新增的仅是独立 fused-kernel BF16 测试，没有 H3 集成或 TeaCache 数值回归，因此不能据此宣称模型端到端 parity。^[PR

head_dim]`，`cos/sin` 保持逐样本 `[batch, seq, dim]` 并通过 `unsqueeze_dim=1` 对齐；优先使用 CANN 支持的 BNSD fused path，仅在不支持的 BNSD tiling shape 下回退 BSND，同时保留每个样本的 M-RoPE 频率，不改 MiniMax H3 DiT 的 `RotaryEmbedding` 路径。\n- 禁止：把 batch-specific frequency 广播、展平或转置成单样本语义；绕过共享 helper 直接调用 NPU 算子而失去 fallback；用 helper 直测代替生产 platform hook 验证，或把该 text-encoder 优化外推到其他 H3 RoPE 路径和平台。\n- 验收：NPU correctness tests 覆盖 BNSD fast shapes、BSND fallback shapes 和不同样本的真实 M-RoPE positions，分别以 NeoX reference 核对 q/k 输出并断言样本频率确实不同；另从平台注册入口验证生产 consumer 已启用 fused path。^[PR #6061]\n\n## MMH3-1k — Qwen3-VL encoder 的 NPU GQA 与 AddRMSNorm 只改变目标平台合同\n\n- 触发：修改 Qwen3-VL text encoder 的 `_scaled_dot_product_attention`、post-attention residual、NPU MiniMax-H3 patch 或 `RMSNorm` 的 optional residual 参数。\n- 强制：通用 encoder helper 保持 causal SDPA 的 reference 语义：当本地 Q heads 多于 K/V heads 时先沿 head 维 repeat-interleave K/V；NPU patch 才保留压缩 BNSD `[B,Q,S,D]` / `[B,KV,S,D]` 输入并调用 `F.scaled_dot_product_attention(..., dropout_p=0.0, is_causal=True, enable_gqa=Q != KV)`。进入该 NPU op 前必须拒绝 K/V head 数不等、零 KV head 和不能整除的 Q:KV 比率。patch 与已有 RoPE/SwiGLU patch 独立且幂等，并仅在 NPU diffusion runtime 已建立、pipeline 尚未加载时注册到此 encoder helper。\n- 强制：shared `RMSNorm(x, residual)` 的语义为先计算 `updated_residual = residual + x`，再以该值 norm，返回 `(normalized, updated_residual)`；MiniMax-H3 decoder 必须将此 updated residual 用于后续 MLP residual add。仅 NPU residual 分支调用 `torch_npu.npu_add_rms_norm`；CUDA、HIP、MUSA 和 XPU residual 分支保留 native equivalent，不能由这个补丁推断其他平台获得 fused AddNorm。\n- 禁止：把 NPU compressed-GQA patch 提升为 shared diffusion Attention/backend policy、改变 DiT attention 或其他 encoder，或用 NPU mock wiring 宣称真实 kernel parity。不得把 PR 的单次 A3 eight-card FL2VA observation（one warmup；249028.120→248662.942 ms）写成跨 workload、checkpoint、topology 或平台的性能保证。\n- 验收：CPU contract

payload width 与最终 logits/target/condition rows 等价；性能和 video/audio quality 只能在固定 PR workload、硬件、steps、seed 与 gate 下复核，不能外推到其他 task 或拓扑。 ^[PR #6173]\n\n## MMH3-1m — H3 modulation 融合必须保持操作顺序、精度与平台回退\n\n- 触发：修改 MiniMax H3 的 AdaLN scale/shift、gated residual、`norm1`/`norm2` 融合、最终输出调制、Triton modulation wrapper 或 TeaCache extractor 的对应调用。\n- 强制：保持 H3 的操作顺序：`norm1` 后执行 indexed scale/shift，attention 后执行 gated residual 并紧接 `norm2` 与第二组 indexed affine，最终层继续在投影前调制；CUDA Triton 路径先以 FP32 计算 `residual + gate * branch`，必须立即经 BF16 再转回 FP32，并以同一个已舍入值写入 `residual_out` 和执行 RMSNorm；该 round trip 必须留在寄存器，不能增加全局内存中间量。CPU fallback 必须保留旧的两步数值边界，即 RMSNorm 结果先转换为输入 dtype，再执行 affine；所有路径都必须按 `combined_indices` 逐行选择同一 shift、scale 和 gate。\n- 禁止：交换 residual、RMSNorm、affine 或 MLP 的顺序；让 CUDA RMSNorm 消费未写入 residual 的未舍入 FP32 更新值；为该修复增加全局中间 materialization；让非 CUDA 平台绕过原生 RMSNorm backend；把 CUDA BF16 exact test、B300 手工 video A/B 或一次 CI 结果描述成跨平台 parity、广泛质量恢复或通用性能保证。\n- 验收：H3 contract test 以 eager 公式分别核对 `norm1` 调制、gated residual+`norm2` 调制和 final-layer 调制，覆盖 index reorder、空行、输出 dtype 与 CPU 两步 fallback；新增 CUDA+Triton fixed-seed BF16 regression 必须以 `torch.equal` 断言 fused `modulated_out` 等于从返回的 `residual_out` 重算的 `rms_norm_indexed_scale_shift`。NPU 测试必须确认使用 `RMSNorm.forward_npu`/`torch_npu.npu_rms_norm` 而非 Triton；B300 video A/B 仅作手工有界复现，PR head 的 Buildkite vllm-omni build #14512 已失败，不能替代此 CUDA contract test。^[PR #6281] ^[PR #6878]\n\n## MMH3-4a — H3 Qwen3-VL NPU 文本 MLP 必须使用 packed gate/up 与融合 SwiGLU\n\n- 触发：修改 MiniMax H3 Qwen3-VL text encoder 的 MLP、`gate_up_proj` packing、NPU fused operator 或对应 platform override。\n- 强制：NPU 路径使用一次 `F.linear(x, self.gate_up_proj.weight)` 生成 packed gate/up，再调用 `torch_npu.npu_swiglu(gate_up, dim=-1)`，最后复用既有 `down_proj`；gate/up 顺序和结果须等价于 `F.silu(gate) * up`，且补丁只作用于 NPU 目标 text MLP，CPU/CUDA 保持原路径。\n- 禁止：在 NPU 上切分 packed 权重后发起两次 `F.linear` 或使用未融合的 SiLU 乘法；只直接调用 helper 而不验证生产注册链；把该优化扩展到 H3 DiT 或其他模型。\n- 验收：NPU 测试以多个 packed shape 对照 split projection reference，并从真实 diffusion runner 初始化入口断言目标 `MiniMaxH3Qwen3VLTextMLP.forward` 已替换且重复初始化幂等；未通过生产入口的 helper 数值测试不能作为 hook 生效证据。^[PR #6167]\n\n## MMH3-4b — H3 DiT 的 packed SwiGLU 必须通过本地

[DIFF-1v](../../components/diffusion/rules.md) 的平台与精度合同，且只改变 H3 DiT，不改变 Qwen3-VL text encoder 的独立 MLP 路径。\n- 禁止：在已选择 fused 路径后重新 `chunk` 并执行两次 native SiLU/乘法；用通用 vLLM activation 类替代本地 diffusion layer；把当前 NPU native fallback 描述成 H3 NPU fused support，或把一次 H3 性能/精度观察推广到其他 task、平台和拓扑。\n- 验收：H3 contract test 用 packed sentinel 验证 gate/up 顺序、半维输出及 `fc2` 输入，并分别覆盖 CUDA fused 与 NPU/XPU/native fallback；固定 checkpoint、seed、steps 和输入对照 native/fused 输出并设数值容差，同时以 kernel/profile 证据确认优化路径确实生效。^[PR #6283]\n" + }, + "head": { + "repos/vllm-omni/models/minimax-h3/rules.md": "---\ntitle: \"MiniMax H3

native，compile tracing\n 直接 native；MUSA 独立走 `F.rms_norm` 以保留 dynamic Inductor 可融合 graph；XPU 走 native，\n NPU 直接调用 `npu_rms_norm` 且没有该\n fallback。RoPE 使用 NeoX `RotaryEmbedding(half_head_dim=False)`：128

native；MindIE 接收 full layout。H3 `_apply_rope` 的 q/k 是 3D `[S,H,D]`；\n MindIE-SD kernel 只收 4D，因此 shared adapter 必须临时变为 `[1,S,H,D]` 并把输出恢复到 3D。\n- 强制：H3 旋转宽度从 config 静态派生为 `rot_dim = 6 *

gated residual 并紧接 `norm2` 与第二组 indexed affine，最终层继续在投影前调制；CUDA Triton 路径先以 FP32 计算 `residual + gate * branch`，必须立即经 BF16 再转回 FP32，并以同一个已舍入值写入 `residual_out` 和执行 RMSNorm；该 round trip 必须留在寄存器，不能增加全局内存中间量。CPU fallback 必须保留旧的两步数值边界，即 RMSNorm 结果先转换为输入 dtype，再执行 affine；所有路径都必须按 `combined_indices` 逐行选择同一 shift、scale 和 gate。\n- 禁止：交换 residual、RMSNorm、affine 或 MLP 的顺序；让 CUDA RMSNorm 消费未写入

MiniMax-H3 INT8 quantization dispatch", + "body": "\r\n\r\n## Purpose\r\n\r\nMiniMax-H3 video generation fails on Ascend when online INT8 quantization is enabled with `--quantization int8`:\r\n\r\n```text\r\nTensor matB not implemented for DT_INT8\r\nUnsupported data types for Cube\r\n```\r\n\r\nThe NPU fused SwiGLU override called `F.linear(x, self.gate_up_proj.weight)` directly. This bypassed the vLLM linear module and its `quant_method.apply()` dispatch, so the INT8 weight was passed to the regular `aclnnMatmul` path, which does not support an INT8 `matB`.\r\n\r\nThis PR calls `self.gate_up_proj(x)` instead. It preserves the packed gate/up projection and fused SwiGLU computation while restoring the configured quantization path, including `npu_quant_matmul` for online INT8. A regression test verifies that the fused MLP invokes the projection module instead of reading its weight directly, and the test is added to the NPU ready suite.\r\n\r\nBoth reported failures end at

HunyuanVideo-1.5 perf step via run_benchmark.py", + "body": "## Purpose\n\nFixes #8074.\n\nThe NPU nightly step **Diffusion X2V · HunyuanVideo-1.5 Perf Test** failed with pytest exit 5 (`collected 1 item / 1 deselected / 0 selected`). PR #7737 migrated `tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json` from the diffusion schema (`benchmark_params[].dataset`) to the omni-bench schema (`benchmark_params[].dataset_name`) and switched the CUDA nightly HunyuanVideo-1.5 step and the NPU Wan 2.2 step to `run_benchmark.py`, but missed this NPU step. It still invoked `run_diffusion_benchmark.py`, whose schema-based `is_diffusion_perf_config` filter (it does not look at the `mark` field) skipped both cases as omni-bench generation cases, so pytest selected 0 tests and Buildkite treated the empty selection as a failure.\n\n## Changes\n\n- `.buildkite/npu/test-npu-nightly.yml`: run the HunyuanVideo-1.5 perf step via `run_benchmark.py` with `BENCHMARK_DIR` and `tests/dfx/perf/results/*.json` artifact upload — same shape as the already-migrated NPU Wan 2.2 step and the fixed CUDA HunyuanVideo-1.5 step.\n- `tests/dfx/perf/tests/test_runner_metadata.py`: add `test_buildkite_perf_steps_use_matching_runner_schema`, which scans every `.buildkite` pipeline and asserts each perf JSON referenced via `--test-config-file` is run by the runner matching its schema (`run_diffusion_benchmark.py` ⇔ `dataset`, `run_benchmark.py` ⇔ `dataset_name`), and pins the issue's JSON to the omni runner.

初始化或 request adapter 路由。\n- 强制：`peft` 保持默认，使用 `DiffusionLoRAManager` 的 cache 与 per-request `LoRARequest`；\n `distill` 必须同时有 startup `lora_path`，在模型加载后只调用一次 pipeline\n `load_lora_weights()`，融合结果在 server 生命周期内持续生效，普通请求不再携带 adapter。\n CLI → default/structured stage → diffusion projection → worker 必须保留 backend、path 与 scale；\n stage 显式值优先于全局注入。\n- 禁止：把 `lora_backend` 写入 PEFT request 的 dead `extra_args`；让 serve CLI 接受多个 PEFT startup\n path；把 distill 描述成可逐请求切换或 LRU cache。pipeline 没有 `load_lora_weights` 时当前只\n warning 并以未修改 base weights 继续，是 fail-open capability gap，不能声称任意 diffusion\n pipeline 已支持。直接 config 仍可能把多 path 送到只接受单 path 的 PEFT manager，CLI 校验\n 不能冒充所有入口的通用门禁。\n- 验收：CLI 正负测试覆盖 distill 无 path、PEFT 多 path、单/多 path 投影与 stage precedence；\n worker 测试分别断言 PEFT manager、distill 单次融合、unsupported warning。`lora_scale` 对\n distill 完全不应用运行时 scale：大于 1 只 warning，小于等于 1 静默忽略；不得声称 scale 对\n fusion 生效。config 类型同时出现 scalar/list 表述，扩展 list scale 前必须先统一 projection\n 与 worker 比较语义。distill caller 还必须传具体 `.safetensors` 文件；目录或 Hub repo 没有\n `weights_name`，当前调用链无法解析。^[PR #2783]\n\n## DIFF-2m — distilled delta 必须按真实 parameter 布局可逆合并\n\n- 触发：修改 checkpoint key conversion、LoRA A/B/bias、packed parameter 或 load/unload。\n- 强制：delta 为 `B @ A`，转到目标 parameter 的 device/dtype 后在 `no_grad` 下原位加；unload\n 必须用同一 state dict、key remap 与布局原位减回。`stacked_params_mapping` 的每个 source shard\n 都必须存在后才按目标 packed 顺序 concat，不能把缺 shard 当零。key remap 依声明顺序累积应用。\n- Qwen 已是 Diffusers `lora_A/lora_B` 且带 `.alpha` 时，先把 `alpha/rank` 折进 B 并移除 alpha；\n alpha 缺 A/B 必须失败。non-Diffusers key 或其余带 alpha 格式再走 pipeline MRO 对应 converter；\n `.to_out.0` 等名称只在转换后映到树内参数。\n- 禁止：静默丢弃非单位 alpha；只验证已消费 key 数却不比较恢复后的 base weight；把 warning 的\n unmatched keys 当严格成功。当前 loader 对 partial/zero-match key 都只 warning 并继续，是\n fail-open gap，审查时必须核对目标模块集合和实际 applied-key count。\n- 兼容边界：融合发生在 `load_model()` 后，对 dense parameter 直接 `param.add_(B @ A)`；目标没有\n TP/HSDP shard-aware delta，也没有量化 stored weight/scale 的合法 mutation 合同。因此当前可证明\n 的 correctness envelope 仅为 dense、unquantized、TP=1；其他组合在宣称支持前必须增加 fail-closed\n compatibility check 或对应 shard/quantization-aware 实现。\n- 验收：CPU 测试覆盖普通/bias/packed load、unload 精确恢复、累积 remap、non-unit alpha、缺配对\n alpha 与 unknown key；真实 smoke 另需固定 adapter、模型 revision、sampling 参数与输出比较。\n 当前 CPU evidence 使用 TP=1 `nn.Linear`；图片/视频附件是人工示例，没有 TP/HSDP/量化、\n 自动质量阈值或性能测量，不能作为持续 correctness gate。^[PR #2783]\n- 模型例外：SenseNova-U1.5 distilled adapter 是 startup-only exactly-one-file one-way fusion；它以\n suffix/exact kohya mapping、fp32 delta 与 parameter `weight_loader` 做 TP sharding，zero-match fail，\n 成功只留 sentinel，partial fuse 失败 abort/reload，不适用本规则的 unload/reversible contract。见\n [SENSENOVA-1a](../../models/sensenova-u1/rules.md#sensenova-1a-u15-distilled-lora-是启动期单文件单向融合)。^[PR

adapter can currently become active when only some of its supplied modules bind. For example, a matching `attn.to_out` module can bind while an unmatched `attn.to_out.0` module is silently ignored. The generic validation only rejects adapters that bind no layers.\n\nReject activation when any supplied module remains unbound, reporting the adapter ID, binding count, unbound names, and expected engine targets. Fused output shape mismatches now raise immediately with the actual `lora_b` dimension and expected `output_slices` total. Replace the existing zero-binding guard with this unified check, preserving rejection of empty adapters. Run model-specific validation afterward and reuse the existing activation-error cleanup to reset uploaded weights and invalidate active/suspended state. Sparse packed targets, such as Q or Q/V without K, remain valid when all supplied modules bind.\n\nAddresses the partial-binding validation portion of #8001. The guide explains that in-memory tensor adapters with renamed keys and PEFT checkpoints with extra keys that pass loading can now fail at activation. Checkpoint-to-engine mapping remains outside this PR.\n\n## Test Plan\n\nRegression coverage includes unmatched module names and incompatible fused output shapes, each while switching from an active or suspended adapter. It checks rollback and successful reactivation of the previous adapter, plus rejection of completely unmatched and empty adapters. Packed-target coverage exercises Q, Q/V, and Q/K/V across three supported name forms.\n\nWith the project test dependencies and vLLM available, run from the repository root:\n\n```bash\n# Minimal regression: fails against the original manager with the new tests applied.\nVLLM_TARGET_DEVICE=cpu python -m pytest \\\n tests/diffusion/lora/test_lora_manager.py::test_lora_manager_rejects_partial_binding_and_rolls_back -q\n\n# Related CPU regression suite.\nVLLM_TARGET_DEVICE=cpu python -m pytest \\\n tests/diffusion/lora/test_lora_manager.py \\\n tests/diffusion/lora/test_base_linear.py \\\n tests/diffusion/lora/test_loader.py \\\n -m 'core_model and cpu' --run-level core_model -q\n\npre-commit run --files \\\n vllm_omni/diffusion/lora/manager.py \\\n tests/diffusion/lora/test_lora_manager.py \\\n docs/user_guide/diffusion/lora.md\n```\n\n**vLLM Version:** 0.29.0 (`98dff2a81d747d1dba01a47f939f48c3526d4206` Python sources loaded via `PYTHONPATH`; native extensions were not built locally).\n\n**vLLM-Omni Commit:** `75390448f10322d93b28173fc44ad421ecca32fd`, based on `9ebef4b`.\n\nLocal environment: macOS / Apple M5, Python 3.12.14, PyTorch 2.13.0, Transformers 5.14.1, Diffusers 0.40.0.

NPU nightly step **Diffusion X2V · HunyuanVideo-1.5 Perf Test** failed with pytest exit 5 (`collected 1 item / 1 deselected / 0 selected`). PR #7737 migrated `tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json` from the diffusion schema (`benchmark_params[].dataset`) to the omni-bench schema (`benchmark_params[].dataset_name`) and switched the CUDA nightly HunyuanVideo-1.5 step and the NPU Wan 2.2 step to `run_benchmark.py`, but missed this NPU step. It still invoked `run_diffusion_benchmark.py`, whose schema-based `is_diffusion_perf_config` filter (it does not look at the `mark` field) skipped both cases as omni-bench generation cases, so pytest selected 0 tests and Buildkite treated the empty selection as a failure.\n\n## Changes\n\n- `.buildkite/npu/test-npu-nightly.yml`: run the HunyuanVideo-1.5 perf step via `run_benchmark.py` with `BENCHMARK_DIR` and `tests/dfx/perf/results/*.json` artifact upload — same shape as the already-migrated NPU Wan 2.2 step and the fixed CUDA HunyuanVideo-1.5 step.\n- `tests/dfx/perf/tests/test_runner_metadata.py`: add `test_buildkite_perf_steps_use_matching_runner_schema`, which scans every `.buildkite` pipeline and asserts each perf JSON referenced via `--test-config-file` is run by the runner matching its schema (`run_diffusion_benchmark.py` ⇔ `dataset`, `run_benchmark.py` ⇔ `dataset_name`), and pins the issue's JSON to the omni runner. This catches the step/JSON mismatch class from #8074 (mixed-schema JSONs, which either runner would silently truncate, are flagged too).\n\n## Test Plan\n\n**vLLM Version:** N/A (CI config + tests only)\n\n**vLLM-Omni Commit:** 98e123f3e0531c5c2d1a74ad1791831ad3ca6e02\n\n- [x] Regression-test scan passes over all 33 runner invocations across `.buildkite` pipelines (0 mismatches)\n- [x] Reproduced the failure mechanism: the old runner selects 0 cases for this JSON; the new runner loads both cases and the step's `-m \"npu and A3\"` filter still selects the A3 case (`test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2`)\n- [x] `check-forbidden-imports` pre-commit hook passes on the changed test file\n- [x] The NPU pipeline renders through the official `_render_test_pipeline` path and the fixed step has the expected commands (full Buildkite jsonschema validation runs in CI)\n\n## Test Result\n\nVerified on Ascend A2 (container `zc-vllm-omni-dev`):\n\n```\n[1] pipeline scan: 33 invocations, 0 mismatches\n[2] issue-file pin OK: hunyuanvideo15_t2v is omni-bench schema\n[3a] run_diffusion_benchmark with issue JSON: 0 case(s) selected (issue state)\n[3b] run_benchmark with issue JSON: 2 case(s) loaded\n test_hunyuanvideo15_t2v_single_device: -m 'npu and A3' selectable = False\n test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2: -m 'npu and A3' selectable = True\n```\n\nNote: the A2 container's vLLM (0.28-era) predates the vLLM 0.30.0 rebase on main, so pytest cannot start there for any test (`ImportError: cannot import name 'KVConnectorBlockState'`); the verifications above were ", + "changed_files": [ + ".buildkite/npu/test-npu-nightly.yml", + "tests/dfx/perf/tests/test_runner_metadata.py" + ], + "diff_excerpt": "--- .buildkite/npu/test-npu-nightly.yml\n@@ -313,13 +313,12 @@ steps:\n HF_HUB_OFFLINE: \"1\"\n DIFFUSION_ATTENTION_BACKEND: TORCH_SDPA\n commands:\n- - export DIFFUSION_BENCHMARK_DIR=tests/dfx/perf/results\n+ - export BENCHMARK_DIR=tests/dfx/perf/results\n - |\n set +e\n- pytest -s -v tests/dfx/perf/scripts/run_diffusion_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n+ pytest -s -v tests/dfx/perf/scripts/run_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n EXIT=$$?\n- buildkite-agent artifact upload \"tests/dfx/perf/results/diffusion_result_*.json\"\n- buildkite-agent artifact upload \"tests/dfx/perf/results/logs/*.log\"\n+ buildkite-agent artifact upload \"tests/dfx/perf/results/*.json\"\n exit $$EXIT\n - label: \":full_moon: Diffusion X2V · Wan 2.2 Function Test\"\n source_file_dependencies: diffusion_wan22_function\n--- tests/dfx/perf/tests/test_runner_metadata.py\n@@ -235,6 +235,53 @@ def test_is_diffusion_perf_config():\n assert is_diffusion_perf_config(custom_edits_cfg)\n \n \n+def test_buildkite_perf_steps_use_matching_runner_schema():\n+ \"\"\"Every Buildkite step must run a perf JSON with the runner matching its schema.\n+\n+ Regression for #8074: the NPU nightly HunyuanVideo-1.5 step kept invoking\n+ ``run_diffusion_benchmark.py`` after the JSON was migrated to the omni-bench\n+ schema (#7737).

— backend 是 startup 配置，不是 request 字段\n\n- 触发：增加 LoRA backend、CLI/deploy 字段、worker 初始化或 request adapter 路由。\n- 强制：`peft` 保持默认，使用 `DiffusionLoRAManager` 的 cache 与 per-request `LoRARequest`；\n `distill` 必须同时有 startup `lora_path`，在模型加载后只调用一次 pipeline\n `load_lora_weights()`，融合结果在 server 生命周期内持续生效，普通请求不再携带 adapter。\n CLI → default/structured stage → diffusion projection → worker 必须保留 backend、path 与 scale；\n stage 显式值优先于全局注入。\n- 禁止：把 `lora_backend` 写入 PEFT request 的 dead `extra_args`；让 serve CLI 接受多个 PEFT startup\n path；把 distill 描述成可逐请求切换或 LRU cache。pipeline 没有 `load_lora_weights` 时当前只\n warning 并以未修改 base weights 继续，是 fail-open capability gap，不能声称任意 diffusion\n pipeline 已支持。直接 config 仍可能把多 path 送到只接受单 path 的 PEFT manager，CLI 校验\n 不能冒充所有入口的通用门禁。\n- 验收：CLI 正负测试覆盖 distill 无 path、PEFT 多 path、单/多 path 投影与 stage precedence；\n worker 测试分别断言 PEFT manager、distill 单次融合、unsupported warning。`lora_scale` 对\n distill 完全不应用运行时 scale：大于 1 只 warning，小于等于 1 静默忽略；不得声称 scale 对\n fusion 生效。config 类型同时出现 scalar/list 表述，扩展 list scale 前必须先统一 projection\n 与 worker 比较语义。distill caller 还必须传具体 `.safetensors` 文件；目录或 Hub repo 没有\n `weights_name`，当前调用链无法解析。^[PR #2783]\n\n## DIFF-2m — distilled delta 必须按真实 parameter 布局可逆合并\n\n- 触发：修改 checkpoint key conversion、LoRA A/B/bias、packed parameter 或 load/unload。\n- 强制：delta 为 `B @ A`，转到目标 parameter 的 device/dtype 后在 `no_grad` 下原位加；unload\n 必须用同一 state dict、key remap 与布局原位减回。`stacked_params_mapping` 的每个 source shard\n 都必须存在后才按目标 packed 顺序 concat，不能把缺 shard 当零。key remap 依声明顺序累积应用。\n- Qwen 已是 Diffusers `lora_A/lora_B` 且带 `.alpha` 时，先把 `alpha/rank` 折进 B 并移除 alpha；\n alpha 缺 A/B 必须失败。non-Diffusers key 或其余带 alpha 格式再走 pipeline MRO 对应 converter；\n `.to_out.0` 等名称只在转换后映到树内参数。\n- 禁止：静默丢弃非单位 alpha；只验证已消费 key 数却不比较恢复后的 base weight；把 warning 的\n unmatched keys 当严格成功。当前 loader 对 partial/zero-match key 都只 warning 并继续，是\n fail-open gap，审查时必须核对目标模块集合和实际 applied-key count。\n- 兼容边界：融合发生在 `load_model()` 后，对 dense parameter 直接 `param.add_(B @ A)`；目标没有\n TP/HSDP shard-aware delta，也没有量化 stored weight/scale 的合法 mutation 合同。因此当前可证明\n 的 correctness envelope 仅为 dense、unquantized、TP=1；其他组合在宣称支持前必须增加 fail-closed\n compatibility check 或对应 shard/quantization-aware 实现。\n- 验收：CPU 测试覆盖普通/bias/packed load、unload 精确恢复、累积 remap、non-unit alpha、缺配对\n alpha 与 unknown key；真实 smoke 另需固定 adapter、模型 revision、sampling 参数与输出比较。\n 当前 CPU evidence 使用 TP=1 `nn.Linear`；图片/视频附件是人工示例，没有 TP/HSDP/量化、\n 自动质量阈值或性能测量，不能作为持续 correctness gate。^[PR #2783]\n- 模型例外：SenseNova-U1.5 distilled adapter 是 startup-only exactly-one-file one-way fusion；它以\n suffix/exact kohya mapping、fp32 delta 与 parameter `weight_loader` 做 TP sharding，zero-match fail，\n 成功只留 sentinel，partial fuse 失败 abort/reload，不适用本规则的 unload/reversible contract。见\n [SENSENOVA-1a](../../models/sensenova-u1/rules.md#sensenova-1a-u15-distilled-lora-是启动期单文件单向融合)。^[PR #6516]\n\n## DIFF-2n — Wan 多文件必须逐位置绑定 architecture-declared transformer\n\n- 触发：Wan 单/双 transformer pipeline 加载 distilled LoRA，或 boundary 部分加载。\n- 强制：单 transformer architecture 只接受一个具体 `.safetensors`；`has_transformer_2` 声明的\n 双 transformer architecture 必须按\n `[transformer, transformer_2]` 位置提供等长文件列表（LightX2V 示例即 high-noise 在前、\n low-noise 在后）。getter 必须接收目标 attribute 名，不能每次都返回第一 transformer。\n 即使 boundary 使其中一个 target 未实例化，仍要求两个 path；未加载 target 记录 warning 并跳过，\n 已加载模块仍保存各自 state dict 供 unload。\n- 禁止：用远端目录加硬编码文件名猜 checkpoint；把两个文件都融合到 `transformer`；从 T2V/I2V\n mixin 接入外推 VACE/S2V 或所有 registry Wan 变体支持。loader 只信任 caller 顺序，无法从文件\n 内容结构性识别 high/low 是否颠倒。\n- 验收：测试用不同 delta 断言两个 transformer 分别变化并在 unload 后恢复；覆盖文件数不匹配、\n 单 transformer、多 transformer与缺失 target；high/low 顺序必须另用固定 checkpoint 的模型级\n 语义/质量证据验证。目标单测覆盖双 transformer 的 load/unload，但没有真实 Wan checkpoint\n 数值或视频质量自动 gate。^[PR #2783]\n\n## DIFF-2o — LTX phase LoRA 必须绑定 recipe 并复用单一 Transformer\n\n- 触发：LTX 多阶段 pipeline 需要在同一 Transformer 上加载官方 raw safetensors refinement LoRA，或需要区分普通两阶段与 merged distilled 两阶段的权重路径。\n- 强制：以 recipe 的 `adapter_slot` 作为唯一 phase switch；普通两阶段使用 `None → ltx_distilled`，full-distilled 两阶段不得加载 LoRA。Sidecar 先查 model root，再按 profile 的官方文件名和仓库回退到 Hub；parser 必须逐一校验 A/B 配对、映射结果、重复目标和 shape。Adapter wrapper 要在 base 权重加载前安装并 remap 到 `base_layer`，保留 Row/Column/QKV 的 rank-local TP slice；未量化 BF16 使用 adapter dtype 中的 layer-fused `B@A`，量化 base 使用 dynamic LoRA。\n- 禁止：为 phase adapter 增加第二个 resident Transformer 或 LTX 专用环境变量；允许 request/static LoRA 与内部 phase adapter 组合；在非 BF16 或量化 base 上声称 layer-fused 可用；对缺失配对、未映射模块或不匹配 shard 静默跳过。\n- 验收：覆盖官方 key mapping、缺失 A/B、unmapped/duplicate target、dynamic 与 fused 精确算术、Row/Column/QKV 本地切片、base 权重不变、phase 进入/退出和 finalize 时机；同时验证 generic `model_paths` sidecar 覆盖与 model-root/Hub fallback。^[PR #5500]\n\n## DIFF-2ab — LoRA linear expand 只能在原输出 slice 上作受限的 inference 累加\n\n- 触发：修改 `DiffusionBaseLinearLayerWithLoRA.apply()` 的 stacked/packed LoRA shrink-then-expand\n 路径、其 active-slice 跳过、输出 slice，或为该路径做 kernel/temporary-allocation 优化。\n- 强制：保留 fully-sharded LoRA 与 `tp_size > 1` 的 `NotImplementedError`，直到 shrink 与 expand\n 之间实现所需 all-gather。将 `x`/base output 展平后，按 `output_slices` 的累计 `offset` 处理每一\n slice；inactive 或空 A/B slice 也必须推进 offset，且 slice metadata 与 A/B stacks 长度不一致必须\n 失败。对 active nonempty slice 先算 `buffer = x_flat @ A.t()`，再以\n `torch.addmm(y_slice, buffer, B.t(), out=y_slice)` 直接累加 expand，**仅当** grad mode disabled 且\n `y_slice`、`buffer`、`B` 三者 dtype 完全相同。\n- 强制：grad mode enabled 或任一上述 dtype 不同，必须保留 functional\n `y_slice[:] = y_slice + buffer @ B.t()`，以维持 autograd 和 output dtype 语义；最终返回的 shape\n 必须恢复为 base output 的原 shape。\n- 禁止：用 `out=` 路径绕过 autograd/dtype fallback，漏掉 inactive/empty slice 的 offset，或把目前的\n fully-sharded+TP rejection 伪称为支持。不要新增 stride/contiguity predicate 来选择该 fast path，也\n 不要把此处的 synthetic microbenchmark 扩大为任意 strided output、完整 diffusion model 或 server\n throughput 的性能承诺。\n- 验收：CPU regression 覆盖 packed multi-slice 的数值结果与每个 active slice 的 in-place `addmm`、\n inactive/empty slice 后的 offset、fully-sharded+TP rejection、autograd backward 时不调用 `out=`，\n 以及 mixed output/LoRA dtype 的 functional fallback。性能证据仅可用固定 shape/dtype/rank、warmup\n 与 iteration 的 CUDA microbenchmark；PR evidence 是 H100 上 BF16 packed synthetic expand 的\n latency/extra-allocation 和 numerical-parity 测量，不替代上述 correctness cases。^[PR #6268]\n\n## DIFF-2x — legacy dynamic manager 的模型专用 loader 与 activation 必须 fail-closed 且事务化\n\n- 触发：修改 `DiffusionLoRAManager` 的 request-time adapter load/bind、模型专用 loader hook、packed/stacked target，或 DLO 下 dynamic sidecar 的 device placement/reallocation。\n- 强制：先让 pipeline 的可选 loader 识别并返回其模型拥有的 `(LoRAModel, PEFTHelper)`，仅在其返回 `None` 时走既有 generic PEFT fallback；专用 loader 的 artifact、target 和全局 A/B shape 必须在 wrapper mutation 前完成校验。manager 必须记录实际绑定的 logical weights，模型 validator 证明完整覆盖；packed QKV/FFN 等布局由模型明确声明或转换，不由共享 manager 猜测。\n- 强制：activation fast path 只可在 active ID 与 scale 都匹配时跳过。首次 mutation 前清除 active ID；任一 `set_lora()` 或 binding validator 异常都 reset 所有 wrapper slot 并保持 inactive，不能保留混合权重或陈旧 fast-path 状态。\n- 强制：DLO owns base-weight streaming only。DLO-enabled manager 在 wrapper replacement 时必须要求可用的 resident-buffer protocol、将 request-switchable A/B sidecars 放在 compute device，且 wrapper 因更大 rank 重新分配后必须重放该 device placement；缺 protocol fail closed。非 DLO path 不得获得此 placement side effect。\n- 禁止：将已识别的专用 artifact 悄悄退回 generic loader；按名称而非真实绑定确认成功；将一个模型的 packed layout/scale 规则泛化给所有 diffusion 模型；失败后继续声明旧 adapter active；把 sidecars 加入 DLO host shards/collective，或靠每 block transfer 伪装为 DLO support。\n- 验收：CPU regressions 覆盖 model hook/fallback、binding completeness、mid-loop failure 后 reset 与旧 adapter retry；DLO mock 覆盖 replacement 的 compute-device placement、缺 resident protocol 的 fail-closed 以及 rank-driven reallocation 后 A/B buffer 仍在该 device。模型 integration 另覆盖 artifact identity、target/shape rejection、packed QKV/FFN binding 和实际 request sampling contract。^[PR #6476] ^[PR #6550]\n\n## DIFF-2ae — PEFT 去激活必须 suspend 切片掩码并保留 uploaded 权重\n\n- 触发：修改 `DiffusionLoRAManager` 的 deactivate/activate、`DiffusionBaseLinearLayerWithLoRA` 的 active-slice mask，或混合 base/adapted 请求切换路径。\n- 强制：deactivate 只 `suspend_lora()`（保存并清零 `_diffusion_lora_active_slices`），保留 stacked A/B；同一 adapter_id 与同一 rounded scale 再激活时 `resume_lora()` 复原掩码，禁止整层 `reset_lora`+rebind。`_suspended_adapter_id` 在真实 reset、rank 驱动的 `create_lora_weights`、新 bind 开始、以及 remove 被 suspend 的 adapter 时必须清空；不同 adapter 或不同 scale 仍走完整 rebind。\n- 禁止：把 suspend 当成可丢弃的 upload；resume 覆盖后注册的新 layer 的 inactive mask；在失败 bind 后仍保留旧 suspended 身份。\n- 验收：CPU 覆盖 suspend/resume、同 id+scale 不 re-upload、不同 scale/id 走 rebind、remove suspended 触发 reset、中途失败后 inactive，以及 add_adapter 后新 layer 不被错误 resume。^[PR #7195]\n\n## DIFF-2ag2 — 绑定零层的 diffusion LoRA adapter 必须失败而不是静默 no-op\n\n- 触发：修改 `DiffusionLoRAManager._bind_adapter_weights` / `_activate_adapter`、\n binding 记账，或 pipeline 可选 `_validate_diffusion_lora_binding` hook。\n- 强制：无论 pipeline 是否提供 binding validator，绑定过程都必须无条件记录实际命中的\n module 名；`bound_lora_names` 为空时立即 `ValueError`，错误信息同时列出 expected\n target modules 与 adapter 收到的 module 名。既有 activate 的 try/except 必须 reset 全部\n wrapper 并保持 inactive，不得留下“已激活但等于 base”的状态。\n- 禁止：仅在有 validator 时才记账；让零绑定激活返回成功或只打 DEBUG；把 diffusers 命名\n checkpoint 对不上 engine layout 的情况当成有效 adapter。\n- 验收：CPU 回归用故意不匹配的 `target_modules` 断言激活抛错、消息含收到的模块名、\n active id 仍为 `None` 且无 `set_lora`；有 validator 的模型路径仍覆盖完整 binding\n completeness。^[PR #7349]\n\n## DIFF-2ag3 — LoRA/ModelOpt 默认只保留通用组件名与通用 fused 映射\n\n- 触发：修改 `DiffusionLoRAManager` 默认扫描组件、ModelOpt `DEFAULT_PACKED_MODULES_MAPPING`，或 pipeline/model 的 `_lora_components` / `_dit_modules` / `packed_modules_mapping`。\n- 强制：manager 默认只扫描通用 diffusers 名 `transformer`、`transformer_2`、`unet`；模型专用属性（如 Bagel 的 `bagel`）必须由 pipeline 经 `_dit_modules` 或 `_lora_components` 声明。ModelOpt 默认只保留通用 attention 融合（`to_qkv`、`add_kv_proj`）；模型专用融合（如 Z-Image `w13`）必须写在模型 `packed_modules_mapping` 并由 adapter 合并。\n- 禁止：把 `dit`/`bagel`/`w13` 等模型私有名硬编码进共享默认；在未扫描真实 denoiser 时宣称 adapter 已生效（零层绑定、输出等同 base）。\n- 验收：Bagel/同类测试 pipeline 必须显式 `_lora_components` 才能发现层；Z-Image 映射在模型侧声明后仍可解析；去掉声明后不得靠框架默认偷跑。^[PR #5907]\n" +

adapters", + "body": "## Purpose\n\nA diffusion LoRA adapter can currently become active when only some of its supplied modules bind. For example, a matching `attn.to_out` module can bind while an unmatched `attn.to_out.0` module is silently ignored. The generic validation only rejects adapters that bind no layers.\n\nReject activation when any supplied module remains unbound, reporting the adapter ID, binding count, unbound names, and expected engine targets. Fused output shape mismatches now raise immediately with the actual `lora_b` dimension and expected `output_slices` total. Replace the existing zero-binding guard with this unified check, preserving rejection of empty adapters. Run model-specific validation afterward and reuse the existing activation-error cleanup to reset uploaded weights and invalidate active/suspended state. Sparse packed targets, such as Q or Q/V without K, remain valid when all supplied modules bind.\n\nAddresses the partial-binding validation portion of #8001. The guide explains that in-memory tensor adapters with renamed keys and PEFT checkpoints with extra keys that pass loading can now fail at activation. Checkpoint-to-engine mapping remains outside this PR.\n\n## Test Plan\n\nRegression coverage includes unmatched module names and incompatible fused output shapes, each while switching from an active or suspended adapter. It checks rollback and successful reactivation of the previous adapter, plus rejection of completely unmatched and empty adapters. Packed-target coverage exercises Q, Q/V, and Q/K/V across three supported name forms.\n\nWith the project test dependencies and vLLM available, run from the repository root:\n\n```bash\n# Minimal regression: fails against the original manager with the new tests applied.\nVLLM_TARGET_DEVICE=cpu python -m pytest \\\n tests/diffusion/lora/test_lora_manager.py::test_lora_manager_rejects_partial_binding_and_rolls_back -q\n\n# Related CPU regression suite.\nVLLM_TARGET_DEVICE=cpu python -m pytest \\\n tests/diffusion/lora/test_lora_manager.py \\\n tests/diffusion/lora/test_base_linear.py \\\n tests/diffusion/lora/test_loader.py \\\n -m 'core_model and cpu' --run-level core_model -q\n\npre-commit run --files \\\n vllm_omni/diffusion/lora/manager.py \\\n tests/diffusion/lora/test_lora_manager.py \\\n docs/user_guide/diffusion/lora.md\n```\n\n**vLLM Version:** 0.29.0 (`98dff2a81d747d1dba01a47f939f48c3526d4206` Python sources loaded via `PYTHONPATH`; native extensions were not built locally).\n\n**vLLM-Omni Commit:** `75390448f10322d93b28173fc44ad421ecca32fd`, based on `9ebef4b`.\n\nLocal environment: macOS / Apple M5, Python 3.12.14, PyTorch 2.13.0, Transformers 5.14.1, Diffusers 0.40.0.

step via run_benchmark.py", + "body": "## Purpose\n\nFixes #8074.\n\nThe NPU nightly step **Diffusion X2V · HunyuanVideo-1.5 Perf Test** failed with pytest exit 5 (`collected 1 item / 1 deselected / 0 selected`). PR #7737 migrated `tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json` from the diffusion schema (`benchmark_params[].dataset`) to the omni-bench schema (`benchmark_params[].dataset_name`) and switched the CUDA nightly HunyuanVideo-1.5 step and the NPU Wan 2.2 step to `run_benchmark.py`, but missed this NPU step. It still invoked `run_diffusion_benchmark.py`, whose schema-based `is_diffusion_perf_config` filter (it does not look at the `mark` field) skipped both cases as omni-bench generation cases, so pytest selected 0 tests and Buildkite treated the empty selection as a failure.\n\n## Changes\n\n- `.buildkite/npu/test-npu-nightly.yml`: run the HunyuanVideo-1.5 perf step via `run_benchmark.py` with `BENCHMARK_DIR` and `tests/dfx/perf/results/*.json` artifact upload — same shape as the already-migrated NPU Wan 2.2 step and the fixed CUDA HunyuanVideo-1.5 step.\n- `tests/dfx/perf/tests/test_runner_metadata.py`: add `test_buildkite_perf_steps_use_matching_runner_schema`, which scans every `.buildkite` pipeline and asserts each perf JSON referenced via `--test-config-file` is run by the runner matching its schema (`run_diffusion_benchmark.py` ⇔ `dataset`, `run_benchmark.py` ⇔ `dataset_name`), and pins the issue's JSON to the omni runner. This catches the step/JSON mismatch class from #8074 (mixed-schema JSONs, which either runner would silently truncate, are flagged too).\n\n## Test Plan\n\n**vLLM Version:** N/A (CI config + tests only)\n\n**vLLM-Omni Commit:** 98e123f3e0531c5c2d1a74ad1791831ad3ca6e02\n\n- [x] Regression-test scan passes over all 33 runner invocations across `.buildkite` pipelines (0 mismatches)\n- [x] Reproduced the failure mechanism: the old runner selects 0 cases for this JSON; the new runner loads both cases and the step's `-m \"npu and A3\"` filter still selects the A3 case (`test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2`)\n- [x] `check-forbidden-imports` pre-commit hook passes on the changed test file\n- [x] The NPU pipeline renders through the official `_render_test_pipeline` path and the fixed step has the expected commands (full Buildkite jsonschema validation runs in CI)\n\n## Test Result\n\nVerified on Ascend A2 (container `zc-vllm-omni-dev`):\n\n```\n[1] pipeline scan: 33 invocations, 0 mismatches\n[2] issue-file pin OK: hunyuanvideo15_t2v is omni-bench schema\n[3a] run_diffusion_benchmark with issue JSON: 0 case(s) selected (issue state)\n[3b] run_benchmark with issue JSON: 2 case(s) loaded\n test_hunyuanvideo15_t2v_single_device: -m 'npu and A3' selectable = False\n test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2: -m 'npu and A3' selectable = True\n```\n\nNote: the A2 container's vLLM (0.28-era) predates the vLLM 0.30.0 rebase on main, so pytest cannot start there for any test (`ImportError: cannot import name 'KVConnectorBlockState'`); the verifications above were ", + "changed_files": [ + ".buildkite/npu/test-npu-nightly.yml", + "tests/dfx/perf/tests/test_runner_metadata.py" + ], + "diff_excerpt": "--- .buildkite/npu/test-npu-nightly.yml\n@@ -313,13 +313,12 @@ steps:\n HF_HUB_OFFLINE: \"1\"\n DIFFUSION_ATTENTION_BACKEND: TORCH_SDPA\n commands:\n- - export DIFFUSION_BENCHMARK_DIR=tests/dfx/perf/results\n+ - export BENCHMARK_DIR=tests/dfx/perf/results\n - |\n set +e\n- pytest -s -v tests/dfx/perf/scripts/run_diffusion_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n+ pytest -s -v tests/dfx/perf/scripts/run_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n EXIT=$$?\n- buildkite-agent artifact upload \"tests/dfx/perf/results/diffusion_result_*.json\"\n- buildkite-agent artifact upload \"tests/dfx/perf/results/logs/*.log\"\n+ buildkite-agent artifact upload \"tests/dfx/perf/results/*.json\"\n exit $$EXIT\n - label: \":full_moon: Diffusion X2V · Wan 2.2 Function Test\"\n source_file_dependencies: diffusion_wan22_function\n--- tests/dfx/perf/tests/test_runner_metadata.py\n@@ -235,6 +235,53 @@ def test_is_diffusion_perf_config():\n assert is_diffusion_perf_config(custom_edits_cfg)\n \n \n+def test_buildkite_perf_steps_use_matching_runner_schema():\n+ \"\"\"Every Buildkite step must run a perf JSON with the runner matching its schema.\n+\n+ Regression for #8074: the NPU nightly HunyuanVideo-1.5 step kept invoking\n+ ``run_diffusion_benchmark.py`` after the JSON was migrated to the omni-bench\n+ schema (#7737).

run_benchmark.py", + "body": "## Purpose\n\nFixes #8074.\n\nThe NPU nightly step **Diffusion X2V · HunyuanVideo-1.5 Perf Test** failed with pytest exit 5 (`collected 1 item / 1 deselected / 0 selected`). PR #7737 migrated `tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json` from the diffusion schema (`benchmark_params[].dataset`) to the omni-bench schema (`benchmark_params[].dataset_name`) and switched the CUDA nightly HunyuanVideo-1.5 step and the NPU Wan 2.2 step to `run_benchmark.py`, but missed this NPU step. It still invoked `run_diffusion_benchmark.py`, whose schema-based `is_diffusion_perf_config` filter (it does not look at the `mark` field) skipped both cases as omni-bench generation cases, so pytest selected 0 tests and Buildkite treated the empty selection as a failure.\n\n## Changes\n\n- `.buildkite/npu/test-npu-nightly.yml`: run the HunyuanVideo-1.5 perf step via `run_benchmark.py` with `BENCHMARK_DIR` and `tests/dfx/perf/results/*.json` artifact upload — same shape as the already-migrated NPU Wan 2.2 step and the fixed CUDA HunyuanVideo-1.5 step.\n- `tests/dfx/perf/tests/test_runner_metadata.py`: add `test_buildkite_perf_steps_use_matching_runner_schema`, which scans every `.buildkite` pipeline and asserts each perf JSON referenced via `--test-config-file` is run by the runner matching its schema (`run_diffusion_benchmark.py` ⇔ `dataset`, `run_benchmark.py` ⇔ `dataset_name`), and pins the issue's JSON to the omni runner. This catches the step/JSON mismatch class from #8074 (mixed-schema JSONs, which either runner would silently truncate, are flagged too).\n\n## Test Plan\n\n**vLLM Version:** N/A (CI config + tests only)\n\n**vLLM-Omni Commit:** 98e123f3e0531c5c2d1a74ad1791831ad3ca6e02\n\n- [x] Regression-test scan passes over all 33 runner invocations across `.buildkite` pipelines (0 mismatches)\n- [x] Reproduced the failure mechanism: the old runner selects 0 cases for this JSON; the new runner loads both cases and the step's `-m \"npu and A3\"` filter still selects the A3 case (`test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2`)\n- [x] `check-forbidden-imports` pre-commit hook passes on the changed test file\n- [x] The NPU pipeline renders through the official `_render_test_pipeline` path and the fixed step has the expected commands (full Buildkite jsonschema validation runs in CI)\n\n## Test Result\n\nVerified on Ascend A2 (container `zc-vllm-omni-dev`):\n\n```\n[1] pipeline scan: 33 invocations, 0 mismatches\n[2] issue-file pin OK: hunyuanvideo15_t2v is omni-bench schema\n[3a] run_diffusion_benchmark with issue JSON: 0 case(s) selected (issue state)\n[3b] run_benchmark with issue JSON: 2 case(s) loaded\n test_hunyuanvideo15_t2v_single_device: -m 'npu and A3' selectable = False\n test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2: -m 'npu and A3' selectable = True\n```\n\nNote: the A2 container's vLLM (0.28-era) predates the vLLM 0.30.0 rebase on main, so pytest cannot start there for any test (`ImportError: cannot import name 'KVConnectorBlockState'`); the verifications above were ", + "changed_files": [ + ".buildkite/npu/test-npu-nightly.yml", + "tests/dfx/perf/tests/test_runner_metadata.py" + ], + "diff_excerpt": "--- .buildkite/npu/test-npu-nightly.yml\n@@ -313,13 +313,12 @@ steps:\n HF_HUB_OFFLINE: \"1\"\n DIFFUSION_ATTENTION_BACKEND: TORCH_SDPA\n commands:\n- - export DIFFUSION_BENCHMARK_DIR=tests/dfx/perf/results\n+ - export BENCHMARK_DIR=tests/dfx/perf/results\n - |\n set +e\n- pytest -s -v tests/dfx/perf/scripts/run_diffusion_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n+ pytest -s -v tests/dfx/perf/scripts/run_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n EXIT=$$?\n- buildkite-agent artifact upload \"tests/dfx/perf/results/diffusion_result_*.json\"\n- buildkite-agent artifact upload \"tests/dfx/perf/results/logs/*.log\"\n+ buildkite-agent artifact upload \"tests/dfx/perf/results/*.json\"\n exit $$EXIT\n - label: \":full_moon: Diffusion X2V · Wan 2.2 Function Test\"\n source_file_dependencies: diffusion_wan22_function\n--- tests/dfx/perf/tests/test_runner_metadata.py\n@@ -235,6 +235,53 @@ def test_is_diffusion_perf_config():\n assert is_diffusion_perf_config(custom_edits_cfg)\n \n \n+def test_buildkite_perf_steps_use_matching_runner_schema():\n+ \"\"\"Every Buildkite step must run a perf JSON with the runner matching its schema.\n+\n+ Regression for #8074: the NPU nightly HunyuanVideo-1.5 step kept invoking\n+ ``run_diffusion_benchmark.py`` after the JSON was migrated to the omni-bench\n+ schema (#7737).

初始化或 request adapter 路由。\n- 强制：`peft` 保持默认，使用 `DiffusionLoRAManager` 的 cache 与 per-request `LoRARequest`；\n `distill` 必须同时有 startup `lora_path`，在模型加载后只调用一次 pipeline\n `load_lora_weights()`，融合结果在 server 生命周期内持续生效，普通请求不再携带 adapter。\n CLI → default/structured stage → diffusion projection → worker 必须保留 backend、path 与 scale；\n stage 显式值优先于全局注入。\n- 禁止：把 `lora_backend` 写入 PEFT request 的 dead `extra_args`；让 serve CLI 接受多个 PEFT startup\n path；把 distill 描述成可逐请求切换或 LRU cache。pipeline 没有 `load_lora_weights` 时当前只\n warning 并以未修改 base weights 继续，是 fail-open capability gap，不能声称任意 diffusion\n pipeline 已支持。直接 config 仍可能把多 path 送到只接受单 path 的 PEFT manager，CLI 校验\n 不能冒充所有入口的通用门禁。\n- 验收：CLI 正负测试覆盖 distill 无 path、PEFT 多 path、单/多 path 投影与 stage precedence；\n worker 测试分别断言 PEFT manager、distill 单次融合、unsupported warning。`lora_scale` 对\n distill 完全不应用运行时 scale：大于 1 只 warning，小于等于 1 静默忽略；不得声称 scale 对\n fusion 生效。config 类型同时出现 scalar/list 表述，扩展 list scale 前必须先统一 projection\n 与 worker 比较语义。distill caller 还必须传具体 `.safetensors` 文件；目录或 Hub repo 没有\n `weights_name`，当前调用链无法解析。^[PR #2783]\n\n## DIFF-2m — distilled delta 必须按真实 parameter 布局可逆合并\n\n- 触发：修改 checkpoint key conversion、LoRA A/B/bias、packed parameter 或 load/unload。\n- 强制：delta 为 `B @ A`，转到目标 parameter 的 device/dtype 后在 `no_grad` 下原位加；unload\n 必须用同一 state dict、key remap 与布局原位减回。`stacked_params_mapping` 的每个 source shard\n 都必须存在后才按目标 packed 顺序 concat，不能把缺 shard 当零。key remap 依声明顺序累积应用。\n- Qwen 已是 Diffusers `lora_A/lora_B` 且带 `.alpha` 时，先把 `alpha/rank` 折进 B 并移除 alpha；\n alpha 缺 A/B 必须失败。non-Diffusers key 或其余带 alpha 格式再走 pipeline MRO 对应 converter；\n `.to_out.0` 等名称只在转换后映到树内参数。\n- 禁止：静默丢弃非单位 alpha；只验证已消费 key 数却不比较恢复后的 base weight；把 warning 的\n unmatched keys 当严格成功。当前 loader 对 partial/zero-match key 都只 warning 并继续，是\n fail-open gap，审查时必须核对目标模块集合和实际 applied-key count。\n- 兼容边界：融合发生在 `load_model()` 后，对 dense parameter 直接 `param.add_(B @ A)`；目标没有\n TP/HSDP shard-aware delta，也没有量化 stored weight/scale 的合法 mutation 合同。因此当前可证明\n 的 correctness envelope 仅为 dense、unquantized、TP=1；其他组合在宣称支持前必须增加 fail-closed\n compatibility check 或对应 shard/quantization-aware 实现。\n- 验收：CPU 测试覆盖普通/bias/packed load、unload 精确恢复、累积 remap、non-unit alpha、缺配对\n alpha 与 unknown key；真实 smoke 另需固定 adapter、模型 revision、sampling 参数与输出比较。\n 当前 CPU evidence 使用 TP=1 `nn.Linear`；图片/视频附件是人工示例，没有 TP/HSDP/量化、\n 自动质量阈值或性能测量，不能作为持续 correctness gate。^[PR #2783]\n- 模型例外：SenseNova-U1.5 distilled adapter 是 startup-only exactly-one-file one-way fusion；它以\n suffix/exact kohya mapping、fp32 delta 与 parameter `weight_loader` 做 TP sharding，zero-match fail，\n 成功只留 sentinel，partial fuse 失败 abort/reload，不适用本规则的 unload/reversible contract。见\n [SENSENOVA-1a](../../models/sensenova-u1/rules.md#sensenova-1a-u15-distilled-lora-是启动期单文件单向融合)。^[PR #6516]\n\n## DIFF-2n — Wan 多文件必须逐位置绑定 architecture-declared transformer\n\n- 触发：Wan 单/双 transformer pipeline 加载 distilled LoRA，或 boundary 部分加载。\n- 强制：单 transformer architecture 只接受一个具体 `.safetensors`；`has_transformer_2` 声明的\n 双 transformer architecture 必须按\n `[transformer, transformer_2]` 位置提供等长文件列表（LightX2V 示例即 high-noise 在前、\n low-noise 在后）。getter 必须接收目标 attribute 名，不能每次都返回第一 transformer。\n 即使 boundary 使其中一个 target 未实例化，仍要求两个 path；未加载 target 记录 warning 并跳过，\n 已加载模块仍保存各自 state dict 供 unload。\n- 禁止：用远端目录加硬编码文件名猜 checkpoint；把两个文件都融合到 `transformer`；从 T2V/I2V\n mixin 接入外推 VACE/S2V 或所有 registry Wan 变体支持。loader 只信任 caller 顺序，无法从文件\n 内容结构性识别 high/low 是否颠倒。\n- 验收：测试用不同 delta 断言两个 transformer 分别变化并在 unload 后恢复；覆盖文件数不匹配、\n 单 transformer、多 transformer与缺失 target；high/low 顺序必须另用固定 checkpoint 的模型级\n 语义/质量证据验证。目标单测覆盖双 transformer 的 load/unload，但没有真实 Wan checkpoint\n 数值或视频质量自动 gate。^[PR #2783]\n\n## DIFF-2o — LTX phase LoRA 必须绑定 recipe 并复用单一 Transformer\n\n- 触发：LTX 多阶段 pipeline 需要在同一 Transformer 上加载官方 raw safetensors refinement LoRA，或需要区分普通两阶段与 merged distilled 两阶段的权重路径。\n- 强制：以 recipe 的 `adapter_slot` 作为唯一 phase switch；普通两阶段使用 `None → ltx_distilled`，full-distilled 两阶段不得加载 LoRA。Sidecar 先查 model root，再按 profile 的官方文件名和仓库回退到 Hub；parser 必须逐一校验 A/B 配对、映射结果、重复目标和 shape。Adapter wrapper 要在 base 权重加载前安装并 remap 到 `base_layer`，保留 Row/Column/QKV 的 rank-local TP slice；未量化 BF16 使用 adapter dtype 中的 layer-fused `B@A`，量化 base 使用 dynamic LoRA。\n- 禁止：为 phase adapter 增加第二个 resident Transformer 或 LTX 专用环境变量；允许 request/static LoRA 与内部 phase adapter 组合；在非 BF16 或量化 base 上声称 layer-fused 可用；对缺失配对、未映射模块或不匹配 shard 静默跳过。\n- 验收：覆盖官方 key mapping、缺失 A/B、unmapped/duplicate target、dynamic 与 fused 精确算术、Row/Column/QKV 本地切片、base 权重不变、phase 进入/退出和 finalize 时机；同时验证 generic `model_paths` sidecar 覆盖与 model-root/Hub fallback。^[PR #5500]\n\n## DIFF-2ab — LoRA linear expand 只能在原输出 slice 上作受限的 inference 累加\n\n- 触发：修改 `DiffusionBaseLinearLayerWithLoRA.apply()` 的 stacked/packed LoRA shrink-then-expand\n 路径、其 active-slice 跳过、输出 slice，或为该路径做 kernel/temporary-allocation 优化。\n- 强制：保留 fully-sharded LoRA 与 `tp_size > 1` 的 `NotImplementedError`，直到 shrink 与 expand\n 之间实现所需 all-gather。将 `x`/base output 展平后，按 `output_slices` 的累计 `offset` 处理每一\n slice；inactive 或空 A/B slice 也必须推进 offset，且 slice metadata 与 A/B stacks 长度不一致必须\n 失败。对 active nonempty slice 先算 `buffer = x_flat @ A.t()`，再以\n `torch.addmm(y_slice, buffer, B.t(), out=y_slice)` 直接累加 expand，**仅当** grad mode disabled 且\n `y_slice`、`buffer`、`B` 三者 dtype 完全相同。\n- 强制：grad mode enabled 或任一上述 dtype 不同，必须保留 functional\n `y_slice[:] = y_slice + buffer @ B.t()`，以维持 autograd 和 output dtype 语义；最终返回的 shape\n 必须恢复为 base output 的原 shape。\n- 禁止：用 `out=` 路径绕过 autograd/dtype fallback，漏掉 inactive/empty slice 的 offset，或把目前的\n fully-sharded+TP rejection 伪称为支持。不要新增 stride/contiguity predicate 来选择该 fast path，也\n 不要把此处的 synthetic microbenchmark 扩大为任意 strided output、完整 diffusion model 或 server\n throughput 的性能承诺。\n- 验收：CPU regression 覆盖 packed multi-slice 的数值结果与每个 active slice 的 in-place `addmm`、\n inactive/empty slice 后的 offset、fully-sharded+TP rejection、autograd backward 时不调用 `out=`，\n 以及 mixed output/LoRA dtype 的 functional fallback。性能证据仅可用固定 shape/dtype/rank、warmup\n 与 iteration 的 CUDA microbenchmark；PR evidence 是 H100 上 BF16 packed synthetic expand 的\n latency/extra-allocation 和 numerical-parity 测量，不替代上述 correctness cases。^[PR #6268]\n\n## DIFF-2x — legacy dynamic manager 的模型专用 loader 与 activation 必须 fail-closed 且事务化\n\n- 触发：修改 `DiffusionLoRAManager` 的 request-time adapter load/bind、模型专用 loader hook、packed/stacked target，或 DLO 下 dynamic sidecar 的 device placement/reallocation。\n- 强制：先让 pipeline 的可选 loader 识别并返回其模型拥有的 `(LoRAModel, PEFTHelper)`，仅在其返回 `None` 时走既有 generic PEFT fallback；专用 loader 的 artifact、target 和全局 A/B shape 必须在 wrapper mutation 前完成校验。manager 必须记录实际绑定的 logical weights，模型 validator 证明完整覆盖；packed QKV/FFN 等布局由模型明确声明或转换，不由共享 manager 猜测。\n- 强制：activation fast path 只可在 active ID 与 scale 都匹配时跳过。首次 mutation 前清除 active ID；任一 `set_lora()` 或 binding validator 异常都 reset 所有 wrapper slot 并保持 inactive，不能保留混合权重或陈旧 fast-path 状态。\n- 强制：DLO owns base-weight streaming only。DLO-enabled manager 在 wrapper replacement 时必须要求可用的 resident-buffer protocol、将 request-switchable A/B sidecars 放在 compute device，且 wrapper 因更大 rank 重新分配后必须重放该 device placement；缺 protocol fail closed。非 DLO path 不得获得此 placement side effect。\n- 禁止：将已识别的专用 artifact 悄悄退回 generic loader；按名称而非真实绑定确认成功；将一个模型的 packed layout/scale 规则泛化给所有 diffusion 模型；失败后继续声明旧 adapter active；把 sidecars 加入 DLO host shards/collective，或靠每 block transfer 伪装为 DLO support。\n- 验收：CPU regressions 覆盖 model hook/fallback、binding completeness、mid-loop failure 后 reset 与旧 adapter retry；DLO mock 覆盖 replacement 的 compute-device placement、缺 resident protocol 的 fail-closed 以及 rank-driven reallocation 后 A/B buffer 仍在该 device。模型 integration 另覆盖 artifact identity、target/shape rejection、packed QKV/FFN binding 和实际 request sampling contract。^[PR #6476] ^[PR #6550]\n\n## DIFF-2ae — PEFT 去激活必须 suspend 切片掩码并保留 uploaded 权重\n\n- 触发：修改 `DiffusionLoRAManager` 的 deactivate/activate、`DiffusionBaseLinearLayerWithLoRA` 的 active-slice mask，或混合 base/adapted 请求切换路径。\n- 强制：deactivate 只 `suspend_lora()`（保存并清零 `_diffusion_lora_active_slices`），保留 stacked A/B；同一 adapter_id 与同一 rounded scale 再激活时 `resume_lora()` 复原掩码，禁止整层 `reset_lora`+rebind。`_suspended_adapter_id` 在真实 reset、rank 驱动的 `create_lora_weights`、新 bind 开始、以及 remove 被 suspend 的 adapter 时必须清空；不同 adapter 或不同 scale 仍走完整 rebind。\n- 禁止：把 suspend 当成可丢弃的 upload；resume 覆盖后注册的新 layer 的 inactive mask；在失败 bind 后仍保留旧 suspended 身份。\n- 验收：CPU 覆盖 suspend/resume、同 id+scale 不 re-upload、不同 scale/id 走 rebind、remove suspended 触发 reset、中途失败后 inactive，以及 add_adapter 后新 layer 不被错误 resume。^[PR #7195]\n\n## DIFF-2ag2 — 绑定零层的 diffusion LoRA adapter 必须失败而不是静默 no-op\n\n- 触发：修改 `DiffusionLoRAManager._bind_adapter_weights` / `_activate_adapter`、\n binding 记账，或 pipeline 可选 `_validate_diffusion_lora_binding` hook。\n- 强制：无论 pipeline 是否提供 binding validator，绑定过程都必须无条件记录实际命中的\n module 名；`bound_lora_names` 为空时立即 `ValueError`，错误信息同时列出 expected\n target modules 与 adapter 收到的 module 名。既有 activate 的 try/except 必须 reset 全部\n wrapper 并保持 inactive，不得留下“已激活但等于 base”的状态。\n- 禁止：仅在有 validator 时才记账；让零绑定激活返回成功或只打 DEBUG；把 diffusers 命名\n checkpoint 对不上 engine layout 的情况当成有效 adapter。\n- 验收：CPU 回归用故意不匹配的 `target_modules` 断言激活抛错、消息含收到的模块名、\n active id 仍为 `None` 且无 `set_lora`；有 validator 的模型路径仍覆盖完整 binding\n completeness。^[PR #7349]\n\n## DIFF-2ag3 — LoRA/ModelOpt 默认只保留通用组件名与通用 fused 映射\n\n- 触发：修改 `DiffusionLoRAManager` 默认扫描组件、ModelOpt `DEFAULT_PACKED_MODULES_MAPPING`，或 pipeline/model 的 `_lora_components` / `_dit_modules` / `packed_modules_mapping`。\n- 强制：manager 默认只扫描通用 diffusers 名 `transformer`、`transformer_2`、`unet`；模型专用属性（如 Bagel 的 `bagel`）必须由 pipeline 经 `_dit_modules` 或 `_lora_components` 声明。ModelOpt 默认只保留通用 attention 融合（`to_qkv`、`add_kv_proj`）；模型专用融合（如 Z-Image `w13`）必须写在模型 `packed_modules_mapping` 并由 adapter 合并。\n- 禁止：把 `dit`/`bagel`/`w13` 等模型私有名硬编码进共享默认；在未扫描真实 denoiser 时宣称 adapter 已生效（零层绑定、输出等同 base）。\n- 验收：Bagel/同类测试 pipeline 必须显式 `_lora_components` 才能发现层；Z-Image 映射在模型侧声明后仍可解析；去掉声明后不得靠框架默认偷跑。^[PR #5907]\n" + }, + "head": { + "repos/vllm-omni/components/diffusion/rules-lora.md": "---\ntitle:

— backend 是 startup 配置，不是 request 字段\n\n- 触发：增加 LoRA backend、CLI/deploy 字段、worker 初始化或 request adapter 路由。\n- 强制：`peft` 保持默认，使用 `DiffusionLoRAManager` 的 cache 与 per-request `LoRARequest`；\n `distill` 必须同时有 startup `lora_path`，在模型加载后只调用一次 pipeline\n `load_lora_weights()`，融合结果在 server 生命周期内持续生效，普通请求不再携带 adapter。\n CLI → default/structured stage → diffusion projection → worker 必须保留 backend、path 与 scale；\n stage 显式值优先于全局注入。\n- 禁止：把 `lora_backend` 写入 PEFT request 的 dead `extra_args`；让 serve CLI 接受多个 PEFT startup\n path；把 distill 描述成可逐请求切换或 LRU cache。pipeline 没有 `load_lora_weights` 时当前只\n warning 并以未修改 base weights 继续，是 fail-open capability gap，不能声称任意 diffusion\n pipeline 已支持。直接 config 仍可能把多 path 送到只接受单 path 的 PEFT manager，CLI 校验\n 不能冒充所有入口的通用门禁。\n- 验收：CLI 正负测试覆盖 distill 无 path、PEFT 多 path、单/多

parameter 布局可逆合并\n\n- 触发：修改 checkpoint key conversion、LoRA A/B/bias、packed parameter 或 load/unload。\n- 强制：delta 为 `B @ A`，转到目标 parameter 的 device/dtype 后在 `no_grad` 下原位加；unload\n 必须用同一 state dict、key remap 与布局原位减回。`stacked_params_mapping` 的每个 source shard\n 都必须存在后才按目标 packed 顺序 concat，不能把缺 shard 当零。key remap 依声明顺序累积应用。\n- Qwen 已是 Diffusers `lora_A/lora_B` 且带 `.alpha` 时，先把 `alpha/rank` 折进 B 并移除 alpha；\n alpha 缺 A/B 必须失败。non-Diffusers key 或其余带 alpha 格式再走 pipeline MRO 对应 converter；\n `.to_out.0` 等名称只在转换后映到树内参数。\n- 禁止：静默丢弃非单位 alpha；只验证已消费 key 数却不比较恢复后的 base weight；把 warning 的\n unmatched keys 当严格成功。当前 loader 对 partial/zero-match key 都只 warning 并继续，是\n fail-open gap，审查时必须核对目标模块集合和实际 applied-key count。\n- 兼容边界：融合发生在 `load_model()` 后，对 dense parameter 直接 `param.add_(B @ A)`；目标没有\n TP/HSDP shard-aware delta，也没有量化 stored weight/scale 的合法 mutation 合同。因此当前可证明\n 的 correctness envelope 仅为 dense、unquantized、TP=1；其他组合在宣称支持前必须增加 fail-closed\n compatibility check 或对应 shard/quantization-aware 实现。\n- 验收：CPU 测试覆盖普通/bias/packed load、unload 精确恢复、累积 remap、non-unit alpha、缺配对\n alpha 与 unknown key；真实 smoke 另需固定 adapter、模型 revision、sampling 参数与输出比较。\n 当前 CPU evidence 使用 TP=1 `nn.Linear`；图片/视频附件是人工示例，没有 TP/HSDP/量化、\n 自动质量阈值或性能测量，不能作为持续 correctness gate。^[PR #2783]\n- 模型例外：SenseNova-U1.5 distilled adapter 是 startup-only exactly-one-file one-way fusion；它以\n suffix/exact kohya mapping、fp32 delta 与 parameter `weight_loader` 做 TP sharding，zero-match fail，\n 成功只留 sentinel，partial fuse 失败 abort/reload，不适用本规则的 unload/reversible contract。见\n [SENSENOVA-1a](../../models/sensenova-u1/rules.md#sensenova-1a-u15-distilled-lora-是启动期单文件单向融合)。^[PR #6516]\n\n## DIFF-2n — Wan 多文件必须逐位置绑定 architecture-declared transformer\n\n- 触发：Wan 单/双 transformer pipeline 加载 distilled LoRA，或 boundary 部分加载。\n- 强制：单 transformer architecture 只接受一个具体 `.safetensors`；`has_transformer_2` 声明的\n 双 transformer architecture 必须按\n `[transformer, transformer_2]` 位置提供等长文件列表（LightX2V 示例即 high-noise 在前、\n low-noise 在后）。getter 必须接收目标 attribute 名，不能每次都返回第一 transformer。\n 即使 boundary 使其中一个 target 未实例化，仍要求两个 path；未加载 target 记录 warning 并跳过，\n 已加载模块仍保存各自 state dict 供 unload。\n- 禁止：用远端目录加硬编码文件名猜 checkpoint；把两个文件都融合到 `transformer`；从 T2V/I2V\n mixin 接入外推 VACE/S2V 或所有 registry Wan 变体支持。loader 只信任 caller 顺序，无法从文件\n 内容结构性识别 high/low 是否颠倒。\n- 验收：测试用不同 delta 断言两个 transformer 分别变化并在 unload 后恢复；覆盖文件数不匹配、\n 单 transformer、多 transformer与缺失 target；high/low 顺序必须另用固定 checkpoint 的模型级\n 语义/质量证据验证。目标单测覆盖双 transformer 的 load/unload，但没有真实 Wan checkpoint\n 数值或视频质量自动 gate。^[PR #2783]\n\n## DIFF-2o — LTX phase LoRA 必须绑定 recipe 并复用单一 Transformer\n\n- 触发：LTX 多阶段 pipeline 需要在同一 Transformer 上加载官方 raw safetensors refinement LoRA，或需要区分普通两阶段与 merged distilled 两阶段的权重路径。\n- 强制：以 recipe 的 `adapter_slot` 作为唯一 phase switch；普通两阶段使用 `None → ltx_distilled`，full-distilled 两阶段不得加载 LoRA。Sidecar 先查 model root，再按 profile 的官方文件名和仓库回退到 Hub；parser 必须逐一校验 A/B 配对、映射结果、重复目标和 shape。Adapter wrapper 要在 base 权重加载前安装并 remap 到 `base_layer`，保留 Row/Column/QKV 的 rank-local TP slice；未量化 BF16 使用 adapter dtype 中的 layer-fused `B@A`，量化 base 使用 dynamic LoRA。\n- 禁止：为 phase adapter 增加第二个 resident Transformer 或 LTX 专用环境变量；允许 request/static LoRA 与内部 phase adapter 组合；在非 BF16 或量化 base 上声称 layer-fused 可用；对缺失配对、未映射模块或不匹配 shard 静默跳过。\n- 验收：覆盖官方 key mapping、缺失 A/B、unmapped/duplicate target、dynamic 与 fused 精确算术、Row/Column/QKV 本地切片、base 权重不变、phase 进入/退出和 finalize 时机；同时验证 generic `model_paths` sidecar 覆盖与 model-root/Hub fallback。^[PR #5500]\n\n## DIFF-2ab — LoRA linear expand 只能在原输出 slice 上作受限的 inference 累加\n\n- 触发：修改 `DiffusionBaseLinearLayerWithLoRA.apply()` 的 stacked/packed LoRA shrink-then-expand\n 路径、其 active-slice 跳过、输出 slice，或为该路径做 kernel/temporary-allocation 优化。\n- 强制：保留 fully-sharded LoRA 与 `tp_size > 1` 的 `NotImplementedError`，直到 shrink 与 expand\n 之间实现所需 all-gather。将 `x`/base output 展平后，按 `output_slices` 的累计 `offset` 处理每一\n slice；inactive 或空 A/B slice 也必须推进 offset，且 slice metadata 与 A/B stacks 长度不一致必须\n 失败。对 active nonempty slice 先算 `buffer = x_flat @ A.t()`，再以\n `torch.addmm(y_slice, buffer, B.t(), out=y_slice)` 直接累加 expand，**仅当** grad mode disabled 且\n `y_slice`、`buffer`、`B` 三者 dtype 完全相同。\n- 强制：grad mode enabled 或任一上述 dtype 不同，必须保留 functional\n `y_slice[:] = y_slice + buffer @ B.t()`，以维持 autograd 和 output dtype 语义；最终返回的 shape\n 必须恢复为 base output 的原 shape。\n- 禁止：用 `out=` 路径绕过 autograd/dtype fallback，漏掉 inactive/empty slice 的 offset，或把目前的\n fully-sharded+TP rejection 伪称为支持。不要新增 stride/contiguity predicate 来选择该 fast path，也\n 不要把此处的 synthetic microbenchmark 扩大为任意 strided output、完整 diffusion model 或 server\n throughput 的性能承诺。\n- 验收：CPU regression 覆盖 packed multi-slice 的数值结果与每个 active slice 的 in-place `addmm`、\n inactive/empty slice 后的 offset、fully-sharded+TP rejection、autograd backward 时不调用 `out=`，\n 以及 mixed output/LoRA dtype 的 functional fallback。性能证据仅可用固定 shape/dtype/rank、warmup\n 与 iteration 的 CUDA microbenchmark；PR evidence 是

fail-closed 且事务化\n\n- 触发：修改 `DiffusionLoRAManager` 的 request-time adapter load/bind、模型专用 loader hook、packed/stacked target，或 DLO 下 dynamic sidecar 的 device placement/reallocation。\n- 强制：先让 pipeline

active when only some of its supplied modules bind. For example, a matching `attn.to_out` module can bind while an unmatched `attn.to_out.0` module is silently ignored. The generic validation only rejects adapters that bind no layers.\n\nReject activation when any supplied module remains unbound, reporting the adapter ID, binding count, unbound names, and expected engine targets. Fused output shape mismatches now raise immediately with the actual `lora_b` dimension and expected `output_slices` total. Replace the existing zero-binding guard with this unified check, preserving rejection of empty adapters. Run model-specific validation afterward and reuse the existing activation-error cleanup to reset uploaded weights and invalidate active/suspended state. Sparse packed targets, such as Q or Q/V without K, remain valid when all supplied modules bind.\n\nAddresses the partial-binding validation portion of #8001. The guide explains that in-memory tensor adapters with renamed keys and PEFT checkpoints with extra keys that pass loading can now fail at activation. Checkpoint-to-engine mapping remains outside this PR.\n\n## Test Plan\n\nRegression coverage includes unmatched module names and incompatible fused output shapes, each while switching from an active or suspended adapter. It checks rollback and successful reactivation of the previous adapter, plus rejection of completely unmatched and empty adapters. Packed-target coverage exercises Q, Q/V, and Q/K/V across three supported name forms.\n\nWith the project test dependencies and vLLM available, run from the repository root:\n\n```bash\n# Minimal regression: fails against the original manager with the new tests applied.\nVLLM_TARGET_DEVICE=cpu python -m pytest \\\n tests/diffusion/lora/test_lora_manager.py::test_lora_manager_rejects_partial_binding_and_rolls_back -q\n\n# Related CPU regression suite.\nVLLM_TARGET_DEVICE=cpu python -m pytest \\\n tests/diffusion/lora/test_lora_manager.py \\\n tests/diffusion/lora/test_base_linear.py \\\n tests/diffusion/lora/test_loader.py \\\n -m 'core_model and cpu' --run-level core_model -q\n\npre-commit run --files \\\n vllm_omni/diffusion/lora/manager.py \\\n tests/diffusion/lora/test_lora_manager.py \\\n docs/user_guide/diffusion/lora.md\n```\n\n**vLLM Version:** 0.29.0 (`98dff2a81d747d1dba01a47f939f48c3526d4206` Python sources loaded via `PYTHONPATH`; native extensions were not built locally).\n\n**vLLM-Omni Commit:** `75390448f10322d93b28173fc44ad421ecca32fd`, based on `9ebef4b`.\n\nLocal environment: macOS / Apple M5, Python 3.12.14, PyTorch 2.13.0, Transformers 5.14.1, Diffusers 0.40.0.

JSON round-trip，分别覆盖 measured/unmeasured TPOT 与选中/未选中 percentile；省略 `num_tpot_samples` 而保留 finite mean 的结果必须被 baseline 拒绝。^[PR #7624]\n\n## BENCH-1g — duplex/eval 媒体解码必须用捆绑 PyAV，不得依赖 host ffmpeg\n\n- 触发：修改 `omni-duplex-eval` 或同类 benchmark 的视频时长、帧抽取、音频 PCM 解码，或重新引入 `ffmpeg`/`ffprobe` subprocess。\n- 强制：媒体路径经 PyAV（`av`）打开/seek/decode/resample；结果不得依赖主机安装的 ffmpeg 版本。帧抽取语义对齐“首个 PTS ≥ 目标时刻”；非 WAV 音频经 `AudioResampler` 并在循环后 `resample(None)` flush 尾部样本。\n- 禁止：`subprocess` 调用 host `ffmpeg`/`ffprobe` 作为默认路径；把“本机 ffmpeg 能跑”当作可复现证据；在已知会挂起的旧 HEVC decoder 上无超时地阻塞 generate 阶段。\n- 验收：覆盖 duration/JPEG/PCM

run_benchmark.py", + "body": "## Purpose\n\nFixes #8074.\n\nThe NPU nightly step **Diffusion X2V · HunyuanVideo-1.5 Perf Test** failed with pytest exit 5 (`collected 1 item / 1 deselected / 0 selected`). PR #7737 migrated `tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json` from the diffusion schema (`benchmark_params[].dataset`) to the omni-bench schema (`benchmark_params[].dataset_name`) and switched the CUDA nightly HunyuanVideo-1.5 step and the NPU Wan 2.2 step to `run_benchmark.py`, but missed this NPU step. It still invoked `run_diffusion_benchmark.py`, whose schema-based `is_diffusion_perf_config` filter (it does not look at the `mark` field) skipped both cases as omni-bench generation cases, so pytest selected 0 tests and Buildkite treated the empty selection as a failure.\n\n## Changes\n\n- `.buildkite/npu/test-npu-nightly.yml`: run the HunyuanVideo-1.5 perf step via `run_benchmark.py` with `BENCHMARK_DIR` and `tests/dfx/perf/results/*.json` artifact upload — same shape as the already-migrated NPU Wan 2.2 step and the fixed CUDA HunyuanVideo-1.5 step.\n- `tests/dfx/perf/tests/test_runner_metadata.py`: add `test_buildkite_perf_steps_use_matching_runner_schema`, which scans every `.buildkite` pipeline and asserts each perf JSON referenced via `--test-config-file` is run by the runner matching its schema (`run_diffusion_benchmark.py` ⇔ `dataset`, `run_benchmark.py` ⇔ `dataset_name`), and pins the issue's JSON to the omni runner. This catches the step/JSON mismatch class from #8074 (mixed-schema JSONs, which either runner would silently truncate, are flagged too).\n\n## Test Plan\n\n**vLLM Version:** N/A (CI config + tests only)\n\n**vLLM-Omni Commit:** 98e123f3e0531c5c2d1a74ad1791831ad3ca6e02\n\n- [x] Regression-test scan passes over all 33 runner invocations across `.buildkite` pipelines (0 mismatches)\n- [x] Reproduced the failure mechanism: the old runner selects 0 cases for this JSON; the new runner loads both cases and the step's `-m \"npu and A3\"` filter still selects the A3 case (`test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2`)\n- [x] `check-forbidden-imports` pre-commit hook passes on the changed test file\n- [x] The NPU pipeline renders through the official `_render_test_pipeline` path and the fixed step has the expected commands (full Buildkite jsonschema validation runs in CI)\n\n## Test Result\n\nVerified on Ascend A2 (container `zc-vllm-omni-dev`):\n\n```\n[1] pipeline scan: 33 invocations, 0 mismatches\n[2] issue-file pin OK: hunyuanvideo15_t2v is omni-bench schema\n[3a] run_diffusion_benchmark with issue JSON: 0 case(s) selected (issue state)\n[3b] run_benchmark with issue JSON: 2 case(s) loaded\n test_hunyuanvideo15_t2v_single_device: -m 'npu and A3' selectable = False\n test_hunyuanvideo15_t2v_cachedit_tp2_vae_patch2: -m 'npu and A3' selectable = True\n```\n\nNote: the A2 container's vLLM (0.28-era) predates the vLLM 0.30.0 rebase on main, so pytest cannot start there for any test (`ImportError: cannot import name 'KVConnectorBlockState'`); the verifications above were ", + "changed_files": [ + ".buildkite/npu/test-npu-nightly.yml", + "tests/dfx/perf/tests/test_runner_metadata.py" + ], + "diff_excerpt": "--- .buildkite/npu/test-npu-nightly.yml\n@@ -313,13 +313,12 @@ steps:\n HF_HUB_OFFLINE: \"1\"\n DIFFUSION_ATTENTION_BACKEND: TORCH_SDPA\n commands:\n- - export DIFFUSION_BENCHMARK_DIR=tests/dfx/perf/results\n+ - export BENCHMARK_DIR=tests/dfx/perf/results\n - |\n set +e\n- pytest -s -v tests/dfx/perf/scripts/run_diffusion_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n+ pytest -s -v tests/dfx/perf/scripts/run_benchmark.py -m \"npu and A3\" --test-config-file tests/dfx/perf/tests/test_hunyuanvideo15_t2v_vllm_omni.json\n EXIT=$$?\n- buildkite-agent artifact upload \"tests/dfx/perf/results/diffusion_result_*.json\"\n- buildkite-agent artifact upload \"tests/dfx/perf/results/logs/*.log\"\n+ buildkite-agent artifact upload \"tests/dfx/perf/results/*.json\"\n exit $$EXIT\n - label: \":full_moon: Diffusion X2V · Wan 2.2 Function Test\"\n source_file_dependencies: diffusion_wan22_function\n--- tests/dfx/perf/tests/test_runner_metadata.py\n@@ -235,6 +235,53 @@ def test_is_diffusion_perf_config():\n assert is_diffusion_perf_config(custom_edits_cfg)\n \n \n+def test_buildkite_perf_steps_use_matching_runner_schema():\n+ \"\"\"Every Buildkite step must run a perf JSON with the runner matching its schema.\n+\n+ Regression for #8074: the NPU nightly HunyuanVideo-1.5 step kept invoking\n+ ``run_diffusion_benchmark.py`` after the JSON was migrated to the omni-bench\n+ schema (#7737).

`control_guidance` 控制。Transfer 必须使用专用 system prompt，同时对 CFG 两支启用；默认在 positive prompt 追加列出 active hints 并要求逐帧遵循形状、位置和运动的 directive，`emphasize_control_in_prompt=false` 才关闭。默认启用 duration/FPS 与 resolution metadata，并以 `negative_metadata_mode=same` 同步到 negative branch；可分别关闭模板，模式只允许 `same`、`inverse`、`none`。Transfer 不自动生成 negative prompt，调用方需显式传入可选参考 prompt。\n- 禁止：把 `weight` 等未声明字段静默当作 `control_weight`；接受负数、非 finite 或全零权重；用单控制归一化权重改变绝对 guidance；让 request 的 `system_prompt`/`use_system_prompt` 覆盖 transfer system prompt；把默认 metadata 或 negative prompt 行为外推到普通 T2I/T2V。\n-

width, aspect_ratio)` bucket；原始请求尺寸先保存到 `COSMOS3_TRANSFER_REQUESTED_SIZE_KEY`，仅用于冲突告警，不能改变控制输入选出的几何。Transfer JSON prompt、以及 I2V/V2V 生成 canvas 的 aspect ratio 元数据必须使用 canonical ratio；若请求或 JSON prompt 的 ratio 与 canvas 冲突，所有 rank 都重写元数据，只有 rank 0 输出 warning。非 canonical canvas 必须映射到最近的受支持 ratio，而不是使用 gcd 形成新标签。\n- 禁止：把 Transfer 的任意 `size=HxW` 当作最终几何或宣称其会被采用；保留控制输入已覆盖的 stale `aspect_ratio`；将元数据重写也放在 `_is_rank_zero()` 条件内导致 rank 间 token ids 不一致；用非 canonical 的精确 gcd ratio 触发无意义的冲突告警。\n- 验收：覆盖 Transfer 请求尺寸与控制 bucket 不一致、请求/JSON ratio 冲突、rank 0 与非 rank 0 的 warning/rewrite 行为，以及 `1104x816`、`832x468` 等近似 canvas 映射到 `4,3`、`16,9` 的回归；JSON prompt 解析后必须逐 rank 得到相同 canonical `aspect_ratio`。^[PR #6325]\n\n## COSMOS-6a — final prompt 仅在 rank zero 以 DEBUG 留存\n\n- 触发：修改 Cosmos3 JSON/metadata prompt formatting、可选 `prompt_suffix`，或该 pipeline 的\n final-prompt observability。\n- 强制：formatting 与可选 suffix 完成后，rank zero 使用同一最终 prompt 和 generation 路径，但只以\n `logger.debug(\"Final prompt: '%s'\", prompt)` 记录；非 rank zero 不发出该 message。\n- 禁止：恢复 INFO emission；把此处调级称为全局 prompt redaction/privacy guarantee；忘记 DEBUG\n 仍会以 plaintext 输出，或借此推断其他 trace、error 或 logger 已修改。\n- 验收：rank-zero test 用含 sentinel 与 suffix

multi-chunk transfer 必须同步分布式 VAE overlap\n\n- 触发：修改 Cosmos3 transfer 的 chunk 边界、`previous_output` 条件帧、VAE decode，或 distributed\n VAE 的 rank 输出/collective 路径。\n- 强制：只有 `vae.distributed_executor` 存在且 `vae.is_distributed_enabled` 可调用并返回 true 时才启用\n distributed VAE 路径。每个非最终 chunk 的 overlap 必须是\n `min(num_conditional_frames, chunk_frames)`；overlap 小于等于零时返回 `None`，且不调用 broadcast。\n active executor 下所有 rank 都对每个需要同步的 overlap 调用 `broadcast_tensor`：rank 0 从已 decode\n output 尾部 slice 并 `contiguous()`，其他 rank 分配与 reference video 同 batch/channel/height/width、但\n frame 维为 overlap 的 receive tensor，且使用 `self.device` 和 `vae.dtype`。仅 rank 0 拼接完整 video/control output；其他\n rank 在 collective 完成后返回本地最终 decoded output 与 metadata。\n- 禁止：仅因 executor 属性存在就进入分布式路径；让任一 rank 跳过应参与的 broadcast；broadcast 整段\n output、从非 rank-zero 的空 output slice overlap，或在非 rank-zero 拼接 full/control output。该同步\n 不得放宽 `COSMOS-2c` 的 session-state guard：flag 开启时 `diffuse_transfer()` 仍须 fail closed，即使\n `_bde_kv_state` 非空。\n- 验收：mock executor 覆盖 enabled/callable gate、rank-zero tail slice、nonzero-rank receive shape/dtype/device、\n 每个 non-final chunk 的 collective 以及 nonpositive-overlap 的 no-broadcast；仅有界的真实回归是一次\n 4×GB300 multi-chunk transfer（Ulysses 4、VAE patch parallelism 4、tiling，1280×720、101 frames、24 FPS、\n 53-frame chunks、5 conditional frames、2 steps），确认完成且 metadata/video 为 101 frames at 24 FPS。\n 该证据不构成广泛 parity、质量或性能声明。^[PR #6920]\n\n## COSMOS-1c — Distilled Cosmos3 必须在加载前拒绝 CFG parallel\n\n- 触发：scheduler `_class_name` 判定 distilled Cosmos3、修改 `cfg_parallel_size` admission，或 distilled 路径的 `guidance_scale` / `negative_prompt` 语义。\n- 强制：在加载 tokenizer/组件之前，若 distilled 且 `cfg_parallel_size > 1`，立即 `ValueError`，并指引 `--cfg-parallel-size 1` 与 `--ulysses-degree` 做多卡。distilled 路径强制 `guidance_scale=1.0`；调用方显式请求其他值时 `warning_once`，并说明 `negative_prompt` 不影响生成。\n- 禁止：静默忽略 CFGP 导致无收益的重复实例；先加载权重再报并行非法；把 distilled 的 guidance override 写成仍消费 negative branch。\n- 验收：参数化覆盖 distilled/non-distilled × `cfg_parallel_size`/`ulysses_degree`，断言 distilled+CFGP>1 在组件加载前失败；guidance resolver 覆盖显式非 1.0 的 warning 与强制 1.0。^[PR #7427]\n" + }, + "head": { +

conditional `und_kv/{i}` 或 unconditional `und_kv_neg/{i}` 分支存 native\n `(K,V)` 引用，并随分支保存 M-RoPE cos/sin；仅未初始化分支可 capture，标准与 RoboLab/action\n 路径都必须传 request ID。generation 开始 reset，整个 dispatch 用

触发：Cosmos3 以默认开启的 guardrails 加载或运行，或修改 Cosmos3 guardrail 依赖与缺包处理。\n- 强制：在公共依赖中声明 `cosmos-guardrail>=0.3.1`，使标准 vLLM-Omni 镜像具备默认 guardrails 所需包；guardrail import 失败时必须立即抛出明确的 `ValueError`，说明 guardrails 已启用但不可用、缺少 `cosmos-guardrail`，并保留 NVIDIA Open Model License Agreement 合规提示。\n- 禁止：依赖用户手动安装额外包才能获得默认行为；缺少 guardrail 包时静默继续、把状态描述为用户主动禁用了 safety checker，或把安装成功外推为 HF authentication、模型质量和其他变体能力已验证。\n- 验收：干净环境安装公共 requirements 后 `cosmos-guardrail` 可导入，Cosmos3 默认 guardrails 路径可进入模型运行；模拟缺少该包时启动/构造 fail fast，错误文本同时包含包名和许可证链接。^[PR #6107]\n\n## COSMOS-5a — Transfer 请求与提示词合同\n\n- 触发：修改 Cosmos3 transfer 的 `edge`、`blur`、`depth`、`seg`、`wsm` 控制提示解析、控制权重或 transfer prompt 构造。\n- 强制：每个 active hint 只接受声明的字段，并将 `control_weight` 校验为 finite、non-negative 且总和为正；按 hint 声明顺序归一化为相对权重，单个正权重归一为 `1.0`，单控制的绝对强度仍由 `control_guidance` 控制。Transfer 必须使用专用 system prompt，同时对 CFG 两支启用；默认在 positive prompt 追加列出 active hints 并要求逐帧遵循形状、位置和运动的 directive，`emphasize_control_in_prompt=false` 才关闭。默认启用 duration/FPS 与 resolution metadata，并以 `negative_metadata_mode=same` 同步到 negative branch；可分别关闭模板，模式只允许 `same`、`inverse`、`none`。Transfer 不自动生成 negative prompt，调用方需显式传入可选参考 prompt。\n- 禁止：把 `weight` 等未声明字段静默当作 `control_weight`；接受负数、非 finite 或全零权重；用单控制归一化权重改变绝对 guidance；让 request 的 `system_prompt`/`use_system_prompt` 覆盖 transfer system prompt；把默认 metadata 或 negative prompt 行为外推到普通 T2I/T2V。\n- 验收：覆盖单/多控制权重归一化、未知字段、负数、全零和 `emphasize_control_in_prompt` ablation；断言 positive/negative 两支的 system prompt、metadata mode、模板和显式/省略 negative prompt；真实 serving 还需固定模型

`size`、`resolution`、`aspect_ratio`、控制输入 bucket 选择、JSON prompt 元数据，或 I2V/V2V 的 canvas ratio 格式化与多 rank prompt 处理。\n- 强制：Transfer 必须根据控制输入和选定 resolution 从 `VIDEO_RES_SIZE_INFO` 选择 canonical `(height, width, aspect_ratio)` bucket；原始请求尺寸先保存到 `COSMOS3_TRANSFER_REQUESTED_SIZE_KEY`，仅用于冲突告警，不能改变控制输入选出的几何。Transfer JSON prompt、以及 I2V/V2V 生成 canvas 的 aspect ratio 元数据必须使用 canonical ratio；若请求或 JSON prompt 的

formatting、可选 `prompt_suffix`，或该 pipeline 的\n final-prompt observability。\n- 强制：formatting 与可选 suffix 完成后，rank zero 使用同一最终 prompt 和 generation 路径，但只以\n `logger.debug(\"Final prompt: '%s'\", prompt)` 记录；非 rank zero 不发出该 message。\n- 禁止：恢复 INFO emission；把此处调级称为全局 prompt redaction/privacy guarantee；忘记 DEBUG\n 仍会以 plaintext 输出，或借此推断其他 trace、error 或 logger 已修改。\n- 验收：rank-zero test 用含 sentinel 与 suffix

multi-chunk transfer 必须同步分布式 VAE overlap\n\n- 触发：修改 Cosmos3 transfer 的 chunk 边界、`previous_output` 条件帧、VAE decode，或 distributed\n VAE 的 rank 输出/collective 路径。\n- 强制：只有 `vae.distributed_executor` 存在且 `vae.is_distributed_enabled` 可调用并返回 true 时才启用\n distributed VAE 路径。每个非最终 chunk 的 overlap 必须是\n `min(num_conditional_frames, chunk_frames)`；overlap 小于等于零时返回 `None`，且不调用 broadcast。\n active executor 下所有

`guidance_scale=1.0`；调用方显式请求其他值时 `warning_once`，并说明 `negative_prompt` 不影响生成。\n- 禁止：静默忽略 CFGP 导致无收益的重复实例；先加载权重再报并行非法；把 distilled 的 guidance override 写成仍消费 negative branch。\n- 验收：参数化覆盖

DIFF-1aa — Diffusers execution backend 不得冒充 native checkpoint identity\n\n- 触发：修改 `diffusion_load_format`、custom pipeline 选择、checkpoint `model_class_name`、\n pre/post-process hook、request batching 能力或 frame interpolation。\n- 强制：`uses_diffusers_adapter()` 只表示实际 execution backend；存在\n `custom_pipeline_args` 时 custom pipeline 优先并令其为 false，即使 load format 是 Diffusers。\n checkpoint 的 native `model_class_name` 继续承载 modality/capability metadata，但 effective\n Diffusers adapter 不运行 native pre/post hooks。batch capability 必须从实际 executor 派生：先\n custom pipeline，再 `DiffusersAdapterPipeline`，否则才查 native class。Diffusers adapter 收到\n frame interpolation 必须 fail fast，因为它交付的 frame 已完成 post-process。\n- 禁止：从 checkpoint metadata 或 load format 单独推导 execution backend、native hooks 或 batching；\n custom pipeline 已接管时仍套 adapter hook；对 adapter output 静默二次 interpolation。\n- 验收：组合覆盖 native、Diffusers adapter、Diffusers load format + custom pipeline 三类配置，断言\n class identity 保留、hook 选择和 batch capability 跟随实际 executor；另验证所有 Diffusers pipeline\n 对 interpolation 抛出明确错误。PR #6749 的自动化测试覆盖这些选择边界，但不证明任意第三方\n custom pipeline 或未来 Diffusers 版本兼容。^[PR #6749]\n\n## DIFF-1d — async output 的 compute 与 output-ready 必须分成两个可观察阶段\n\n- 触发：把 diffusion D2H/SHM packing 移到 worker 后台线程，或修改 result pump、`collective_rpc`、\n batch output split。\n- 强制：GPU compute 完成只释放下一次 forward；最终输出必须等 side-stream event、D2H 和 SHM packing\n 完成后再 resolve。每个 worker-owned result queue 由唯一 pump reader 分发，batch 结果按 request 映射\n 拆分；step-mode 保留同步路径。\n- 禁止：在 compute-done 时把未完成 device tensor 当最终 artifact；让多个线程同读一个 result queue；\n 用同步 `.cpu()` 掩盖 stream ordering 或让下一 step 重写源 buffer。\n- 验收：覆盖 compute-done、output-ready、RPC error、batch split、queue cleanup 与非 CUDA/step-mode\n fallback。^[PR #5864]\n\n## DIFF-1g — 每个 worker result queue 必须有唯一 reader 与显式 SHM owner\n\n- 触发：request-mode worker result queue、async pump、multi-rank reply 或 tensor/NumPy SHM serialization。\n- 强制：每个 worker 创建独立 result queue，executor 为每个 queue 建唯一 pump；RPC/output future 按\n envelope ID 路由，DP reply 保留 rank tag。递归 pack/unpack 必须覆盖 tagged/RPC envelope、nested\n dict/list/tuple、tensor 与大于 1MB 的 non-object ndarray；reader copy 后 close+unlink segment。\n- 禁止：多个 worker 共写一个 queue 后假设 reply 不冲突；pump 与同步 caller 同读；object ndarray\n 进入 raw SHM；只释放顶层 handle 而泄漏 nested segment。\n- 验收：真实 spawn workers 各建 queue，传 nested tensor/video/audio ndarray，验证 tag/order/dtype/value，\n 所有 pump 停止、queue 关闭、SHM name 不再可 attach。当前测试覆盖成功 round-trip；partial pack、\n unpack/copy 异常时已创建 segment 的回收仍缺 fault-injection。^[PR #5864]\n\n## DIFF-1h — request-mode shutdown 必须幂等、有界且按 engine→task/IPC 顺序完成\n\n- 触发：worker async-output thread、executor process cleanup、inline client 或 orchestrator pre-mark shutdown。\n- 强制：worker 用 sentinel 停 async thread，并证明 thread 已停止后才 teardown 它仍可能访问的\n model/queue/SHM；executor 以全局 deadline join 全部 workers，统一 terminate survivors，再 join\n pumps/fail futures。inline client 区分 shutting-down 与\n shutdown-complete，在 lock 内先 close engine 再等待 thread-pool；调用方复用 sampling params 时在 task\n 启动前同步 clone。\n- 禁止：把 orchestrator 的 pre-mark 当作 teardown 已完成；每 worker 单独耗完整 timeout；先等待可能\n 阻塞在 engine RPC 的 executor 再 close engine；二次 shutdown 重复释放。\n- 验收：normal、worker shutdown exception、premarked、concurrent/repeated shutdown、blocked RPC、async\n output active 与 forced termination 都验证无 live thread/process/queue/SHM，future 到达终态。目标常量\n 为 worker 15s 全局 join、5s terminate grace、async thread 10s、pump 2s；async thread 超时仍存活时\n 虽保留 result queue，却仍先调用 `worker.shutdown()`，model teardown 可能与 live output thread 竞态，\n 且没有后续强制 thread/SHM/queue 回收证明。final 2×B300 rerun提供一次普通 TP2 与\n DLO DP2 clean exit，但不替代 fault matrix。^[PR #5864]\n\n## DIFF-1j — Engine 构造失败必须释放已启动的 Executor\n\n- 触发：`DiffusionEngine.__init__` 在 executor 已启动后初始化 Scheduler、runtime state、execute\n function 或 logging。\n- 强制：任一步失败都 best-effort 关闭已赋值 Scheduler、shutdown executor，再原样重抛根因；\n cleanup 异常只能记录。此时同步状态可能尚未建立，不能调用完整 `close()`。\n- 禁止：构造异常直接逃逸并遗留 worker/monitor/GPU allocation，或用 cleanup 异常遮蔽初始错误。\n- 验收：注入 Scheduler initialization failure，断言 close/shutdown 各一次且异常 identity 不变；\n 另覆盖 cleanup 自身失败不遮蔽根因。^[PR #5550]\n\n## DIFF-2k — DLO AllGather DP wave 必须完整兼容或不可复用地 fail closed\n\n- 触发：DLO+AllGather、DP>1 允许 concurrent request，或修改 multi-rank `execute_model` RPC。\n- 强制：只在 DLO+AllGather+DP>1 放宽 single-request pipeline admission；preflight 复用完整\n `RequestBatchSamplingParamsKey`，另比较 canonical `extra_args` 并拒绝空 prompt。shape、CFG、denoise\n schedule、output count、LoRA 与任何 future control-flow 字段必须相同；prompt/token length 和\n seed/generator 可不同。multi-rank reply 按 `dp_rank` tag 排序，step mode 从\n `dp_rank * (TP*SP*PP*CFG)` 选择 replica primary result queue。\n- 禁止：为凑 wave 静默改变用户 wait 配置；用 step count+extra_args 代替完整 key；partial collective\n timeout 后复用 process group。少于 DP 个 request 时 rank 以 `dp_rank % len(reqs)` 重复执行已有 request，\n 只消费前 request-count 个排序输出；这是 correctness fallback 与额外计算，不得称为满 DP throughput。\n- 验收：完整/partial wave、mismatch shape/CFG/steps/output/LoRA/extra_args、空 prompt、不同 seed/token\n length、rank tag 重排与 primary-rank topology 都覆盖；timeout 必须将 engine 标记失败、同步 shutdown\n 并通知 failure callback。timeout 默认 600s 且在 import 时从 env 读取，不是 request deadline。final\n 2×B300 evidence 覆盖 ordinary TP2 与 H3 DLO DP2 的错误 wave→同 engine recovery→无 active child；\n 仍只绑定 eager+CUDNN exact topology，不能推广到一般 DP/SP 或替代 per-replica SP/mmap redesign。\n ^[PR #5864]\n\n## DIFF-1i — AAC mux 必须显式标记输入时间零点\n\n- 触发：修改共享 mux 的 audio-frame timestamp、codec/container 或 video API 输出。\n- 强制：共享 `mux_video_audio_bytes()` 在构造 AAC frame 时设 `pts=0`、\n `time_base=1/sample_rate`，让 MP4 以负 priming timestamp 表达 encoder delay，\n 避免把 delay 暴露成前导静音。这是共享 mux caller 的 blast radius，不是\n MiniMax H3 专属。\n- 禁止：从负 AAC packet PTS 外推其他 codec/container、audio sample/duration/\n content、唇音同步或完整 A/V alignment。\n- 验收：目标 focused test 解 mux 后断言第一个有 PTS 的 AAC packet `PTS<0`；\n 样本和 A/V 对齐结论仍需独立的端到端波形/时序验收。^[PR #5978]\n\n## DIFF-1q — request-mode async output 交付必须覆盖传输、竞态与生命周期\n\n- 触发：修改 request-mode diffusion 的 async D2H/SHM output、`MessageQueue` 写入、batch split、result pump、future bookkeeping，或 worker 的 sleep/内存释放生命周期。\n- 强制：per-request tensor view 的 IPC packing 必须按 `max(view_bytes, storage_bytes)` 判断并只把 view 内容放入 SHM；`execute_batch` 注册 split map 时必须在同一锁下接管早到的 batch output；`result_mq` 的 `COMPUTE_DONE` 与 `OUTPUT_READY` 写入必须串行化；result pump 必须先完成 SHM unpack，再在 `_futures_lock` 下原子 resolve waiter 或缓存 completed output；worker 执行 `sleep`/`handle_sleep_task` 和本地 sleep task 前必须等待 `drain_async_outputs()`。两个 `DiffusionEngine` wait 路径必须逐次解析 `VLLM_OMNI_ASYNC_OUTPUT_TIMEOUT`：正数 float 可覆盖 600s 默认值；无效值告警后回退默认值；超时日志必须给出可调的变量名与 executor bookkeeping。\n- 禁止：按 view 大小判断而让共享 batch storage 被 pickle 重复发送；在 split map 建立前缓存一个无人消费的 batch-level output；让多个线程并发写单写者 `MessageQueue`；SHM unpack 期间释放 future 锁导致 waiter orphan；释放 device memory 时仍允许后台 D2H/SHM 线程读取源 tensor；把单 tensor storage-aware packing 当作 aggregate serialized message 已不会溢出的证明，也不得据此推断外部 HTTP 视频传输已优化；不得在 request path 因无效 timeout 环境值抛出异常，也不得只修改其中一个 wait 路径。\n- 验收：覆盖 per-request shared-storage wire-size regression、早到和晚到的 batch `OUTPUT_READY`、已有 waiter 与缓存 future 的原子 resolution、并发 result queue writer 无 overlap、pending output 的 drain/timeout 及 sleep-before-drain 顺序；同时验证 non-sleep RPC 不 drain、SHM unpack/error path、超时诊断状态和 worker shutdown cleanup，以及两个 wait 路径的默认值、正数 integer/float override、逐次重读与非数/非正值的 warning+fallback。^[PR #6023] ^[PR #6255]\n\n## DIFF-1r — 共享 Future resolve 必须对取消竞态 fail-safe\n\n- 触发：修改 diffusion result pump、共享 `_rpc_futures`/`_output_futures`、`asyncio.wait_for()` 超时、请求 abort 或 shutdown future cleanup。\\n- 强制：共享 Future 在 `done()` 检查后仍必须通过 `try_set_result`/`try_set_exception` 解析，并在 helper 内捕获 `concurrent.futures.InvalidStateError`，丢弃取消或已完成 Future 的晚到结果/异常，使 singleton pump 继续运行；仅 freshly-created 且尚未共享的本地 Future 可直接解析。\\n- 禁止：把 `not fut.done()` 与 `set_result()`/`set_exception()` 当作原子操作；在共享 Future 上保留未保护的 resolve 调用；让取消竞态异常逃逸并杀死 result pump，随后仍以健康检查通过推断任务会完成。\\n- 验收：用 `done()` 固定返回 false 但实际已取消的 racy Future 覆盖 `COMPUTE_DONE`、`OUTPUT_READY`、batch split 与 shutdown cleanup，断言 pump 不抛 `InvalidStateError`、取消 Future 保持取消、同批健康 Future 仍完成，并回归相邻并发测试。\\n^[PR #5983]\n\n## DIFF-1ab — spawned StageDiffusionProc 必须在 engine 前重载通用插件\n\n- 触发：修改 `StageDiffusionProc.run_diffusion_proc`、spawned diffusion engine startup 或 general plugin loader。\n- 强制：child 先安装 parent-death signal 与 SIGTERM/SIGINT handlers，再 `load_omni_general_plugins()`，最后构造 engine/proc；spawn fresh interpreter 不继承 parent plugin side effects。\n- 禁止：在 parent import/pin 后假定 child 已注册 loader hook，或将此 ordering 外推为任意 plugin 或完整模型 startup 成功。\n- 验收：mock parent-death signal、SIGTERM/SIGINT handlers、plugin reload 与 construction 的精确顺序；\n plugin failure 必须在 engine construction 前原样传播。GGUF child reload 仍须独立 full-model proof。^[PR #6750]\n\n## DIFF-1s — diffusion output type 必须从模型声明闭合到 topology 与 formatter\n\n- 触发：diffusion pipeline 产生 image/video/audio/action 等输出，或修改 model metadata、registry alias、topology `final_output_type`、formatter/post-process 与 multiprocess 传递路径。\n- 强制：metadata 按 direct class → metadata alias → registry architecture class/alias → default\n 的顺序解析；model class 与 registry alias 必须解析到同一 canonical output metadata。默认单\n stage config、multi-stage final stage、video endpoint capability 与 `OmniRequestOutput` formatter\n 必须传播同一类型。未知模型才回 image；非媒体输出使用稳定的 `DiffusionOutput.output` key，并注册\n 可跨 orchestrator multiprocess 边界解析的 module-level post-process callable。SANA 的\n `SanaVideoPipeline` 与 `SanaImageToVideoPipeline` 都必须 direct metadata 声明\n `final_output_type=\"video\"`；这是 serving metadata 分类，非 I2V input schema、denoise、topology\n 或 VAE 合同变更。LTX 的 `LTX2DistilledOneStagePipeline` 与显式\n `LTX2DistilledTwoStagePipeline` 必须都经 metadata alias 收敛到 canonical\n `LTX2DistilledPipeline` 的 video metadata；同一结论还必须在 registry\n architecture→pipeline class 解析路径成立。\n- 禁止：只在 topology 标 video 但 formatter 仍发 image；要求每个 stage 都是 diffusion 才允许 video final；遗漏已注册 video alias 后静默回 image；用 ndarray 形状猜语义，或把局部 closure 作为跨进程 hook。\n- 验收：逐个 canonical class/alias 断言 default 与 multi-stage final type，video/image endpoint 正负 capability 及最终 output type；action 另验证 post-process callable 可跨目标进程边界使用，最终 output 保留 stable key、shape、dtype 和有限性。PR #6953 的 CPU metadata unit test 只断言两种 SANA class 均分类为 video；PR #6847 的同类 CPU metadata test 只覆盖显式 LTX distilled two-stage alias 分类。两者都不是新的 endpoint、真实模型或 online/offline E2E 证据。^[PR #4222] ^[PR #5885] ^[PR #6847] ^[PR #6953]\n\n## DIFF-4z — 全 rank RPC 必须执行，但仅 reply owner 保留输出\n\n- 触发：RPC 在所有 rank 执行，而 `output_rank` 或 DP replica primary 决定唯一回复者；结果可能\n 携带 device-resident diffusion 输出。\n- 强制：所有应执行 rank 都调用目标方法以维持 collective 语义；`should_reply=false` 时在\n `_worker_busy_loop` 绑定返回值之前返回 `(None, False)`，只有回复 rank 保留并 enqueue 原结果。\n- 禁止：因不回复而跳过执行，或把非回复 rank 的 device-resident 结果交回 busy loop 并保留到下次\n 请求覆盖。\n- 验收：非回复 rank 断言目标方法确实执行且返回 `None, False`；回复 rank 断言返回同一对象。测试\n 必须覆盖实际采用的 reply-selection 形式。当前证据只覆盖 CPU 单元级返回所有权，不证明 GPU\n 显存下降或真实多进程回收时序。^[PR #6989]\n\n## DIFF-9a — 共享 PyAV 预构造帧 mux 必须闭合资源与音频时间零点\n\n- 触发：修改共享 diffusion 的预构造 PyAV 视频帧 mux、可选音频 mux、container cleanup 或编码器异常传播。\n- 强制：`mux_av_video_audio_bytes()` 必须在 context manager 内打开并配置 MP4 video/audio streams，消费 `Iterable[av.VideoFrame]` 后 flush video encoder；音频按 `fltp` 和 mono/stereo layout 构造，并以 `pts=0`、`time_base=1/sample_rate` 标记输入时间零点。`audio_sample_rate` 可为 `None`：仅在 audio waveform 存在时内部解析为 44.1 kHz，video-only 不创建 audio stream，也不需要采样率。成功和 generator、encoder、mux 异常都必须退出 context 关闭 container，同时原样传播原始错误。\n- 禁止：在 generator 消费前或 context 外打开/使用 container；只在成功路径手工 close；吞掉帧生成或编码异常后静默改走其他 muxer；把 mock container cleanup 或单一 CPU 运行误认为完整跨硬件 A/V parity。\n- 验收：测试覆盖预构造 `gbrp` 帧的 H.264 mux、无音频/mono/stereo 音频、`None` rate 的 video-only 与 audio 44.1 kHz default、AAC 首个有效 packet 的负 priming PTS、video flush 和 container close；让 frame generator 在中途抛错并断言 container 已关闭且异常 identity 保持，再用固定媒体输入执行 ffprobe 与完整 FFmpeg 解码。^[PR #6288] ^[PR #6499]\n\n## DIFF-11a — 单 GPU diffusion executor 必须保持进程内故障与生命周期语义\n\n- 触发：新增或修改单 GPU diffusion executor、inline worker RPC、设备故障处理或 executor shutdown 生命周期。\n- 强制：单 GPU 的 `uni` 路径必须在 engine 进程内构造并驱动 `WorkerWrapperBase`，仍初始化一个 rank 的 distributed environment，但不得创建 worker subprocess、`MessageQueue` 或 IPC 输出段；`collective_rpc` 直接调用 worker，保留 reply-rank

identity\n\n- 触发：修改 `diffusion_load_format`、custom pipeline 选择、checkpoint `model_class_name`、\n pre/post-process hook、request batching 能力或 frame interpolation。\n- 强制：`uses_diffusers_adapter()` 只表示实际 execution backend；存在\n `custom_pipeline_args` 时 custom pipeline 优先并令其为 false，即使 load format 是 Diffusers。\n checkpoint 的 native `model_class_name` 继续承载 modality/capability metadata，但 effective\n Diffusers adapter 不运行 native pre/post hooks。batch capability 必须从实际 executor 派生：先\n custom pipeline，再 `DiffusersAdapterPipeline`，否则才查 native class。Diffusers adapter 收到\n frame interpolation 必须 fail fast，因为它交付的 frame 已完成 post-process。\n- 禁止：从 checkpoint metadata 或 load format 单独推导 execution backend、native hooks 或 batching；\n custom pipeline 已接管时仍套 adapter hook；对 adapter output 静默二次 interpolation。\n- 验收：组合覆盖 native、Diffusers adapter、Diffusers load format + custom pipeline 三类配置，断言\n class identity 保留、hook 选择和 batch capability 跟随实际 executor；另验证所有 Diffusers pipeline\n 对 interpolation 抛出明确错误。PR #6749 的自动化测试覆盖这些选择边界，但不证明任意第三方\n custom pipeline 或未来 Diffusers 版本兼容。^[PR #6749]\n\n## DIFF-1d — async output 的 compute 与 output-ready 必须分成两个可观察阶段\n\n- 触发：把 diffusion D2H/SHM packing 移到 worker 后台线程，或修改 result pump、`collective_rpc`、\n batch output split。\n- 强制：GPU compute 完成只释放下一次 forward；最终输出必须等 side-stream event、D2H 和 SHM packing\n 完成后再 resolve。每个 worker-owned result queue 由唯一 pump reader 分发，batch 结果按 request 映射\n 拆分；step-mode 保留同步路径。\n- 禁止：在 compute-done 时把未完成 device tensor 当最终 artifact；让多个线程同读一个 result queue；\n 用同步 `.cpu()` 掩盖 stream ordering 或让下一 step 重写源

触发：request-mode worker result queue、async pump、multi-rank reply 或 tensor/NumPy SHM serialization。\n- 强制：每个 worker 创建独立 result queue，executor 为每个 queue 建唯一 pump；RPC/output future 按\n envelope ID 路由，DP reply 保留 rank tag。递归 pack/unpack 必须覆盖 tagged/RPC envelope、nested\n dict/list/tuple、tensor 与大于 1MB 的 non-object ndarray；reader copy 后 close+unlink segment。\n- 禁止：多个 worker 共写一个 queue 后假设 reply 不冲突；pump 与同步 caller 同读；object ndarray\n 进入 raw SHM；只释放顶层 handle 而泄漏 nested segment。\n- 验收：真实 spawn workers 各建 queue，传 nested tensor/video/audio ndarray，验证 tag/order/dtype/value，\n 所有 pump 停止、queue 关闭、SHM name 不再可 attach。当前测试覆盖成功 round-trip；partial pack、\n unpack/copy 异常时已创建 segment 的回收仍缺 fault-injection。^[PR #5864]\n\n## DIFF-1h — request-mode shutdown 必须幂等、有界且按 engine→task/IPC 顺序完成\n\n- 触发：worker async-output thread、executor process cleanup、inline client 或 orchestrator pre-mark shutdown。\n- 强制：worker 用 sentinel 停 async thread，并证明 thread 已停止后才 teardown 它仍可能访问的\n model/queue/SHM；executor 以全局 deadline join 全部 workers，统一 terminate survivors，再 join\n pumps/fail futures。inline client 区分 shutting-down 与\n shutdown-complete，在 lock 内先 close engine 再等待 thread-pool；调用方复用 sampling params 时在 task\n 启动前同步 clone。\n- 禁止：把 orchestrator 的 pre-mark 当作 teardown 已完成；每 worker 单独耗完整 timeout；先等待可能\n 阻塞在 engine RPC 的 executor 再 close engine；二次 shutdown 重复释放。\n- 验收：normal、worker shutdown exception、premarked、concurrent/repeated shutdown、blocked RPC、async\n output active 与 forced termination 都验证无 live thread/process/queue/SHM，future 到达终态。目标常量\n 为 worker 15s 全局 join、5s terminate

canonical `extra_args` 并拒绝空 prompt。shape、CFG、denoise\n schedule、output count、LoRA 与任何 future control-flow 字段必须相同；prompt/token length 和\n seed/generator 可不同。multi-rank reply 按 `dp_rank` tag 排序，step mode 从\n `dp_rank * (TP*SP*PP*CFG)` 选择 replica primary result queue。\n- 禁止：为凑 wave 静默改变用户 wait 配置；用 step count+extra_args 代替完整 key；partial collective\n timeout 后复用 process group。少于 DP 个 request 时 rank 以 `dp_rank % len(reqs)` 重复执行已有 request，\n 只消费前 request-count 个排序输出；这是 correctness fallback 与额外计算，不得称为满 DP throughput。\n- 验收：完整/partial wave、mismatch shape/CFG/steps/output/LoRA/extra_args、空 prompt、不同 seed/token\n length、rank tag 重排与 primary-rank topology 都覆盖；timeout 必须将 engine 标记失败、同步 shutdown\n 并通知 failure callback。timeout 默认 600s 且在 import 时从 env 读取，不是 request deadline。final\n 2×B300 evidence 覆盖

timestamp 表达 encoder delay，\n 避免把 delay 暴露成前导静音。这是共享 mux caller 的 blast radius，不是\n MiniMax H3 专属。\n- 禁止：从负 AAC packet PTS 外推其他 codec/container、audio sample/duration/\n content、唇音同步或完整 A/V

diffusion 的 async D2H/SHM output、`MessageQueue` 写入、batch split、result pump、future bookkeeping，或 worker 的 sleep/内存释放生命周期。\n- 强制：per-request tensor view 的 IPC packing 必须按 `max(view_bytes, storage_bytes)` 判断并只把 view 内容放入 SHM；`execute_batch` 注册 split map 时必须在同一锁下接管早到的 batch output；`result_mq` 的 `COMPUTE_DONE` 与 `OUTPUT_READY` 写入必须串行化；result pump 必须先完成 SHM unpack，再在 `_futures_lock` 下原子 resolve waiter 或缓存 completed output；worker 执行 `sleep`/`handle_sleep_task` 和本地 sleep task 前必须等待 `drain_async_outputs()`。两个 `DiffusionEngine` wait 路径必须逐次解析 `VLLM_OMNI_ASYNC_OUTPUT_TIMEOUT`：正数 float 可覆盖 600s 默认值；无效值告警后回退默认值；超时日志必须给出可调的变量名与 executor bookkeeping。\n- 禁止：按 view 大小判断而让共享 batch storage 被 pickle 重复发送；在 split map 建立前缓存一个无人消费的 batch-level output；让多个线程并发写单写者 `MessageQueue`；SHM unpack 期间释放 future 锁导致 waiter orphan；释放 device memory 时仍允许后台 D2H/SHM 线程读取源 tensor；把单 tensor storage-aware packing 当作 aggregate serialized message 已不会溢出的证明，也不得据此推断外部 HTTP 视频传输已优化；不得在 request path 因无效 timeout 环境值抛出异常，也不得只修改其中一个 wait 路径。\n- 验收：覆盖 per-request shared-storage wire-size regression、早到和晚到的 batch `OUTPUT_READY`、已有 waiter 与缓存 future 的原子 resolution、并发 result queue writer 无 overlap、pending output 的 drain/timeout 及 sleep-before-drain 顺序；同时验证 non-sleep RPC 不 drain、SHM unpack/error path、超时诊断状态和 worker shutdown cleanup，以及两个 wait 路径的默认值、正数 integer/float override、逐次重读与非数/非正值的 warning+fallback。^[PR #6023] ^[PR #6255]\n\n## DIFF-1r — 共享 Future resolve 必须对取消竞态 fail-safe\n\n- 触发：修改 diffusion result pump、共享 `_rpc_futures`/`_output_futures`、`asyncio.wait_for()` 超时、请求 abort 或 shutdown future cleanup。\\n- 强制：共享 Future 在 `done()` 检查后仍必须通过 `try_set_result`/`try_set_exception` 解析，并在 helper 内捕获 `concurrent.futures.InvalidStateError`，丢弃取消或已完成 Future 的晚到结果/异常，使 singleton pump 继续运行；仅 freshly-created 且尚未共享的本地 Future 可直接解析。\\n- 禁止：把 `not fut.done()` 与 `set_result()`/`set_exception()` 当作原子操作；在共享 Future 上保留未保护的 resolve 调用；让取消竞态异常逃逸并杀死 result pump，随后仍以健康检查通过推断任务会完成。\\n- 验收：用 `done()` 固定返回 false 但实际已取消的 racy Future 覆盖 `COMPUTE_DONE`、`OUTPUT_READY`、batch split 与 shutdown cleanup，断言 pump 不抛 `InvalidStateError`、取消 Future 保持取消、同批健康 Future 仍完成，并回归相邻并发测试。\\n^[PR #5983]\n\n## DIFF-1ab — spawned StageDiffusionProc 必须在 engine 前重载通用插件\n\n- 触发：修改 `StageDiffusionProc.run_diffusion_proc`、spawned diffusion engine startup 或 general plugin loader。\n- 强制：child 先安装 parent-death signal 与 SIGTERM/SIGINT handlers，再 `load_omni_general_plugins()`，最后构造 engine/proc；spawn fresh interpreter 不继承 parent plugin side effects。\n- 禁止：在 parent import/pin 后假定 child 已注册 loader hook，或将此 ordering 外推为任意 plugin 或完整模型 startup 成功。\n- 验收：mock parent-death signal、SIGTERM/SIGINT handlers、plugin reload 与 construction 的精确顺序；\n plugin failure 必须在 engine construction 前原样传播。GGUF child reload 仍须独立 full-model proof。^[PR #6750]\n\n## DIFF-1s — diffusion output type 必须从模型声明闭合到 topology 与 formatter\n\n- 触发：diffusion pipeline 产生 image/video/audio/action 等输出，或修改 model metadata、registry alias、topology `final_output_type`、formatter/post-process 与 multiprocess 传递路径。\n- 强制：metadata 按 direct class → metadata alias → registry architecture class/alias → default\n 的顺序解析；model class 与 registry alias 必须解析到同一 canonical output metadata。默认单\n stage config、multi-stage final stage、video endpoint capability 与 `OmniRequestOutput` formatter\n 必须传播同一类型。未知模型才回 image；非媒体输出使用稳定的 `DiffusionOutput.output` key，并注册\n 可跨 orchestrator multiprocess 边界解析的 module-level post-process callable。SANA 的\n `SanaVideoPipeline` 与 `SanaImageToVideoPipeline` 都必须 direct metadata 声明\n `final_output_type=\"video\"`；这是 serving metadata 分类，非 I2V input schema、denoise、topology\n 或 VAE 合同变更。LTX 的 `LTX2DistilledOneStagePipeline` 与显式\n `LTX2DistilledTwoStagePipeline` 必须都经 metadata alias 收敛到 canonical\n `LTX2DistilledPipeline` 的 video metadata；同一结论还必须在 registry\n architecture→pipeline class 解析路径成立。\n- 禁止：只在 topology 标 video 但 formatter 仍发 image；要求每个 stage 都是 diffusion 才允许 video final；遗漏已注册 video alias 后静默回 image；用 ndarray 形状猜语义，或把局部 closure 作为跨进程 hook。\n- 验收：逐个 canonical class/alias 断言 default 与 multi-stage final type，video/image endpoint 正负 capability 及最终 output type；action 另验证 post-process callable 可跨目标进程边界使用，最终 output 保留 stable key、shape、dtype 和有限性。PR #6953 的 CPU metadata unit test 只断言两种 SANA class 均分类为 video；PR #6847 的同类 CPU metadata test 只覆盖显式 LTX distilled two-stage alias 分类。两者都不是新的 endpoint、真实模型或 online/offline E2E 证据。^[PR #4222] ^[PR #5885] ^[PR #6847] ^[PR #6953]\n\n## DIFF-4z — 全 rank RPC 必须执行，但仅 reply owner 保留输出\n\n- 触发：RPC 在所有 rank 执行，而 `output_rank` 或 DP replica primary 决定唯一回复者；结果可能\n 携带 device-resident diffusion 输出。\n- 强制：所有应执行 rank 都调用目标方法以维持 collective 语义；`should_reply=false` 时在\n `_worker_busy_loop` 绑定返回值之前返回 `(None, False)`，只有回复 rank 保留并 enqueue 原结果。\n- 禁止：因不回复而跳过执行，或把非回复 rank 的 device-resident 结果交回 busy loop 并保留到下次\n 请求覆盖。\n- 验收：非回复 rank 断言目标方法确实执行且返回 `None, False`；回复 rank 断言返回同一对象。测试\n 必须覆盖实际采用的 reply-selection 形式。当前证据只覆盖 CPU 单元级返回所有权，不证明 GPU\n 显存下降或真实多进程回收时序。^[PR #6989]\n\n## DIFF-9a — 共享 PyAV 预构造帧 mux 必须闭合资源与音频时间零点\n\n- 触发：修改共享 diffusion 的预构造 PyAV 视频帧 mux、可选音频 mux、container cleanup 或编码器异常传播。\n- 强制：`mux_av_video_audio_bytes()` 必须在 context manager 内打开并配置 MP4 video/audio streams，消费 `Iterable[av.VideoFrame]` 后 flush video encoder；音频按 `fltp` 和 mono/stereo layout 构造，并以 `pts=0`、`time_base=1/sample_rate` 标记输入时间零点。`audio_sample_rate` 可为 `None`：仅在 audio waveform 存在时内部解析为 44.1 kHz，video-only 不创建 audio stream，也不需要采样率。成功和 generator、encoder、mux 异常都必须退出 context 关闭 container，同时原样传播原始错误。\n- 禁止：在 generator 消费前或 context 外打开/使用 container；只在成功路径手工 close；吞掉帧生成或编码异常后静默改走其他 muxer；把 mock container cleanup 或单一 CPU 运行误认为完整跨硬件 A/V parity。\n- 验收：测试覆盖预构造 `gbrp` 帧的 H.264 mux、无音频/mono/stereo 音频、`None` rate 的 video-only 与 audio 44.1 kHz default、AAC 首个有效 packet 的负 priming PTS、video flush 和 container close；让 frame generator 在中途抛错并断言 container 已关闭且异常 identity 保持，再用固定媒体输入执行 ffprobe 与完整 FFmpeg 解码。^[PR #6288] ^[PR #6499]\n\n## DIFF-11a — 单

rank 的 distributed environment，但不得创建 worker subprocess、`MessageQueue` 或 IPC 输出段；`collective_rpc` 直接调用 worker，保留 reply-rank 的返回形状，recoverable request error 留在请求级，sticky accelerator fault 必须 latch executor failure、只触发一次 failure callback，并让 `check_health()` 抛出 `EngineDeadError`。\n- 禁止：单 GPU 默认继续走 `mp`，多 GPU 选择 `uni`，把 inline `timeout` 描述成可强制的 RPC deadline，或把所有 worker exception 都升级为 engine death；设备上下文已中毒后不得继续报告健康，也不得让部分构造失败或重复 shutdown 遗留 worker、callback、缓存或 device allocation。\n- 验收：覆盖 omitted/显式 backend/多 GPU 的选择矩阵、直接 RPC 与返回形状、recoverable error、CUDA/NPU sticky fault、callback once、health failure、部分构造 cleanup 和幂等 shutdown；真实单 GPU smoke 还须验证一 rank group、`InlineStageDiffusionClient`、真实 `DiffusionOutput` 流程、worker shutdown，以及固定 seed 下与 pinned `mp` 的输出一致性，mock 不能替代这些证据。 ^[PR

lifecycle", + "body": "## Purpose\n\nFix the in-process diffusion worker lifecycle regression exposed after #7685 added sequential sleep-enabled `uni` / `mp` custom-pipeline coverage.\n\nOn ROCm, a completed inline engine can leave CuMem-tracked model allocations alive after shutdown. The next sleep-enabled inline worker then fails while opening its weight pool:\n\n```text\nAssertionError: Sleep mode can only be used for one instance per process.\n```\n\nThat custom-pipeline failure happens after the worker has initialized process-global distributed groups. If construction then exits without shutting the worker down, the following engine fails with:\n\n```text\nRuntimeError: model parallel state must be empty before initialization;\nfound dp, cfg, sp, pp, vllm_tp, vllm_dp, vllm_pp\n```\n\nThe deterministic sequence occurred in the AMD Custom Pipeline job in:\n\n- [AMD #12465](https://buildkite.com/vllm/vllm-omni-amd-ci/builds/12465#01a0c582-c7ac-48c8-a726-2fd1a5d5eee0)\n- [AMD #12466](https://buildkite.com/vllm/vllm-omni-amd-ci/builds/12466#01a0c5a3-e008-474c-af88-5598b2f7885f)\n- [AMD #12468](https://buildkite.com/vllm/vllm-omni-amd-ci/builds/12468#01a0c634-bb4f-47b2-9e8b-c76531e9fd4e)\n\n## Changes\n\n- Make `DiffusionWorker.shutdown()` idempotent and deterministic:\n - detach model, LoRA, profiler, sleep-buffer, and request-state references;\n - stop offloader and KV-prefetch resources before distributed teardown;\n - close the active KV-transfer manager, including the legacy fallback;\n - destroy connector, workspace, and distributed state best-effort;\n - synchronize, collect model objects, release owned CuMem pools, and check final allocator usage.\n- Track `_owns_sleep_pool` so a worker releases only the pool it acquired.\n- Unwind a worker when default model-runner initialization fails after `init_device()`.\n- Unwind a successfully created worker when custom-pipeline re-initialization fails inside `WorkerWrapperBase`.\n- Preserve the original initialization exception if best-effort cleanup itself fails.\n- Add unit coverage for initialization-failure paths, cleanup ordering, CuMem release ordering, ownership, idempotency, and cleanup-error masking.\n\nThe strict single-instance allocator assertion remains unchanged.\n\n## Upstream integration\n\nCurrent revision: `940ceff464a07c6172ff62ba397419a18d48eab9` on `main` `6daf5b30f07cc0b3db87766d22fdf433f8a1a7c9`.\n\nThe rebase incorporated the worker and lifecycle changes from merged #6264 while retaining this PR's cleanup guarantees. Exact-head AMD #12664 passed the Custom Pipeline, Wan22, and FlashAttention/AITER targets. Its broad shard 3 unit run caught that a cleanup exception could mask the original custom-pipeline initialization error; the current revision fixes that regression and is being requalified.\n\n## Test Plan\n\nFocused unit coverage:\n\n```bash\npytest -q tests/diffusion/test_worker_wrapper_base.py \\\n -k 'init_failure or shutdown' -o addopts=''\n```\n\nROCm regression coverage:\n\n```bash\npytest

初始化或 request adapter 路由。\n- 强制：`peft` 保持默认，使用 `DiffusionLoRAManager` 的 cache 与 per-request `LoRARequest`；\n `distill` 必须同时有 startup `lora_path`，在模型加载后只调用一次 pipeline\n `load_lora_weights()`，融合结果在 server 生命周期内持续生效，普通请求不再携带 adapter。\n CLI → default/structured stage → diffusion projection → worker 必须保留 backend、path 与 scale；\n stage 显式值优先于全局注入。\n- 禁止：把 `lora_backend` 写入 PEFT request 的 dead `extra_args`；让 serve CLI 接受多个 PEFT startup\n path；把 distill 描述成可逐请求切换或 LRU cache。pipeline 没有 `load_lora_weights` 时当前只\n warning 并以未修改 base weights 继续，是 fail-open capability gap，不能声称任意 diffusion\n pipeline 已支持。直接 config 仍可能把多 path 送到只接受单 path 的 PEFT manager，CLI 校验\n 不能冒充所有入口的通用门禁。\n- 验收：CLI 正负测试覆盖 distill 无 path、PEFT 多 path、单/多 path 投影与 stage precedence；\n worker 测试分别断言 PEFT manager、distill 单次融合、unsupported warning。`lora_scale` 对\n distill 完全不应用运行时 scale：大于 1 只 warning，小于等于 1 静默忽略；不得声称 scale 对\n fusion 生效。config 类型同时出现 scalar/list 表述，扩展 list scale 前必须先统一 projection\n 与 worker 比较语义。distill caller 还必须传具体 `.safetensors` 文件；目录或 Hub repo 没有\n `weights_name`，当前调用链无法解析。^[PR #2783]\n\n## DIFF-2m — distilled delta 必须按真实 parameter 布局可逆合并\n\n- 触发：修改 checkpoint key conversion、LoRA A/B/bias、packed parameter 或 load/unload。\n- 强制：delta 为 `B @ A`，转到目标 parameter 的 device/dtype 后在 `no_grad` 下原位加；unload\n 必须用同一 state dict、key remap 与布局原位减回。`stacked_params_mapping` 的每个 source shard\n 都必须存在后才按目标 packed 顺序 concat，不能把缺 shard 当零。key remap 依声明顺序累积应用。\n- Qwen 已是 Diffusers `lora_A/lora_B` 且带 `.alpha` 时，先把 `alpha/rank` 折进 B 并移除 alpha；\n alpha 缺 A/B 必须失败。non-Diffusers key 或其余带 alpha 格式再走 pipeline MRO 对应 converter；\n `.to_out.0` 等名称只在转换后映到树内参数。\n- 禁止：静默丢弃非单位 alpha；只验证已消费 key 数却不比较恢复后的 base weight；把 warning 的\n unmatched keys 当严格成功。当前 loader 对 partial/zero-match key 都只 warning 并继续，是\n fail-open gap，审查时必须核对目标模块集合和实际 applied-key count。\n- 兼容边界：融合发生在 `load_model()` 后，对 dense parameter 直接 `param.add_(B @ A)`；目标没有\n TP/HSDP shard-aware delta，也没有量化 stored weight/scale 的合法 mutation 合同。因此当前可证明\n 的 correctness envelope 仅为 dense、unquantized、TP=1；其他组合在宣称支持前必须增加 fail-closed\n compatibility check 或对应 shard/quantization-aware 实现。\n- 验收：CPU 测试覆盖普通/bias/packed load、unload 精确恢复、累积 remap、non-unit alpha、缺配对\n alpha 与 unknown key；真实 smoke 另需固定 adapter、模型 revision、sampling 参数与输出比较。\n 当前 CPU evidence 使用 TP=1 `nn.Linear`；图片/视频附件是人工示例，没有 TP/HSDP/量化、\n 自动质量阈值或性能测量，不能作为持续 correctness gate。^[PR #2783]\n- 模型例外：SenseNova-U1.5 distilled adapter 是 startup-only exactly-one-file one-way fusion；它以\n suffix/exact kohya mapping、fp32 delta 与 parameter `weight_loader` 做 TP sharding，zero-match fail，\n 成功只留 sentinel，partial fuse 失败 abort/reload，不适用本规则的 unload/reversible contract。见\n [SENSENOVA-1a](../../models/sensenova-u1/rules.md#sensenova-1a-u15-distilled-lora-是启动期单文件单向融合)。^[PR #6516]\n\n## DIFF-2n — Wan 多文件必须逐位置绑定 architecture-declared transformer\n\n- 触发：Wan 单/双 transformer pipeline 加载 distilled LoRA，或 boundary 部分加载。\n- 强制：单 transformer architecture 只接受一个具体 `.safetensors`；`has_transformer_2` 声明的\n 双 transformer architecture 必须按\n `[transformer, transformer_2]` 位置提供等长文件列表（LightX2V 示例即 high-noise 在前、\n low-noise 在后）。getter 必须接收目标 attribute 名，不能每次都返回第一 transformer。\n 即使 boundary 使其中一个 target 未实例化，仍要求两个 path；未加载 target 记录 warning 并跳过，\n 已加载模块仍保存各自 state dict 供 unload。\n- 禁止：用远端目录加硬编码文件名猜 checkpoint；把两个文件都融合到 `transformer`；从 T2V/I2V\n mixin 接入外推 VACE/S2V 或所有 registry Wan 变体支持。loader 只信任 caller 顺序，无法从文件\n 内容结构性识别 high/low 是否颠倒。\n- 验收：测试用不同 delta 断言两个 transformer 分别变化并在 unload 后恢复；覆盖文件数不匹配、\n 单 transformer、多 transformer与缺失 target；high/low 顺序必须另用固定 checkpoint 的模型级\n 语义/质量证据验证。目标单测覆盖双 transformer 的 load/unload，但没有真实 Wan checkpoint\n 数值或视频质量自动 gate。^[PR #2783]\n\n## DIFF-2o — LTX phase LoRA 必须绑定 recipe 并复用单一 Transformer\n\n- 触发：LTX 多阶段 pipeline 需要在同一 Transformer 上加载官方 raw safetensors refinement LoRA，或需要区分普通两阶段与 merged distilled 两阶段的权重路径。\n- 强制：以 recipe 的 `adapter_slot` 作为唯一 phase switch；普通两阶段使用 `None → ltx_distilled`，full-distilled 两阶段不得加载 LoRA。Sidecar 先查 model root，再按 profile 的官方文件名和仓库回退到 Hub；parser 必须逐一校验 A/B 配对、映射结果、重复目标和 shape。Adapter wrapper 要在 base 权重加载前安装并 remap 到 `base_layer`，保留 Row/Column/QKV 的 rank-local TP slice；未量化 BF16 使用 adapter dtype 中的 layer-fused `B@A`，量化 base 使用 dynamic LoRA。\n- 禁止：为 phase adapter 增加第二个 resident Transformer 或 LTX 专用环境变量；允许 request/static LoRA 与内部 phase adapter 组合；在非 BF16 或量化 base 上声称 layer-fused 可用；对缺失配对、未映射模块或不匹配 shard 静默跳过。\n- 验收：覆盖官方 key mapping、缺失 A/B、unmapped/duplicate target、dynamic 与 fused 精确算术、Row/Column/QKV 本地切片、base 权重不变、phase 进入/退出和 finalize 时机；同时验证 generic `model_paths` sidecar 覆盖与 model-root/Hub fallback。^[PR #5500]\n\n## DIFF-2ab — LoRA linear expand 只能在原输出 slice 上作受限的 inference 累加\n\n- 触发：修改 `DiffusionBaseLinearLayerWithLoRA.apply()` 的 stacked/packed LoRA shrink-then-expand\n 路径、其 active-slice 跳过、输出 slice，或为该路径做 kernel/temporary-allocation 优化。\n- 强制：保留 fully-sharded LoRA 与 `tp_size > 1` 的 `NotImplementedError`，直到 shrink 与 expand\n 之间实现所需 all-gather。将 `x`/base output 展平后，按 `output_slices` 的累计 `offset` 处理每一\n slice；inactive 或空 A/B slice 也必须推进 offset，且 slice metadata 与 A/B stacks 长度不一致必须\n 失败。对 active nonempty slice 先算 `buffer = x_flat @ A.t()`，再以\n `torch.addmm(y_slice, buffer, B.t(), out=y_slice)` 直接累加 expand，**仅当** grad mode disabled 且\n `y_slice`、`buffer`、`B` 三者 dtype 完全相同。\n- 强制：grad mode enabled 或任一上述 dtype 不同，必须保留 functional\n `y_slice[:] = y_slice + buffer @ B.t()`，以维持 autograd 和 output dtype 语义；最终返回的 shape\n 必须恢复为 base output 的原 shape。\n- 禁止：用 `out=` 路径绕过 autograd/dtype fallback，漏掉 inactive/empty slice 的 offset，或把目前的\n fully-sharded+TP rejection 伪称为支持。不要新增 stride/contiguity predicate 来选择该 fast path，也\n 不要把此处的 synthetic microbenchmark 扩大为任意 strided output、完整 diffusion model 或 server\n throughput 的性能承诺。\n- 验收：CPU regression 覆盖 packed multi-slice 的数值结果与每个 active slice 的 in-place `addmm`、\n inactive/empty slice 后的 offset、fully-sharded+TP rejection、autograd backward 时不调用 `out=`，\n 以及 mixed output/LoRA dtype 的

currently become active when only some of its supplied modules bind. For example, a matching `attn.to_out` module can bind while an unmatched `attn.to_out.0` module is silently ignored. The generic validation only rejects adapters that bind no layers.\n\nReject activation when any supplied module remains unbound, reporting the adapter ID, binding count, unbound names, and expected engine targets. Fused output shape mismatches now raise immediately with the actual `lora_b` dimension and expected `output_slices` total. Replace the existing zero-binding guard with this unified check, preserving rejection of empty adapters. Run model-specific validation afterward and reuse the existing activation-error cleanup to reset uploaded weights and invalidate active/suspended state. Sparse packed targets, such as Q or Q/V without K, remain valid when all supplied modules bind.\n\nAddresses the partial-binding validation portion of #8001. The guide explains that in-memory tensor adapters with renamed keys and PEFT checkpoints with extra keys that pass loading can now fail at activation. Checkpoint-to-engine mapping remains outside this PR.\n\n## Test Plan\n\nRegression coverage includes unmatched module names and incompatible fused output shapes, each while switching from an active or suspended adapter. It checks rollback and successful reactivation of the previous adapter, plus rejection of completely unmatched and empty adapters. Packed-target coverage exercises Q, Q/V, and Q/K/V across three supported name forms.\n\nWith the project test dependencies and vLLM available, run from the repository root:\n\n```bash\n# Minimal regression: fails against the original manager with the new tests applied.\nVLLM_TARGET_DEVICE=cpu python -m pytest \\\n tests/diffusion/lora/test_lora_manager.py::test_lora_manager_rejects_partial_binding_and_rolls_back -q\n\n# Related CPU regression suite.\nVLLM_TARGET_DEVICE=cpu python -m pytest \\\n tests/diffusion/lora/test_lora_manager.py \\\n tests/diffusion/lora/test_base_linear.py \\\n tests/diffusion/lora/test_loader.py \\\n -m 'core_model and cpu' --run-level core_model -q\n\npre-commit run --files \\\n vllm_omni/diffusion/lora/manager.py \\\n tests/diffusion/lora/test_lora_manager.py \\\n docs/user_guide/diffusion/lora.md\n```\n\n**vLLM Version:** 0.29.0 (`98dff2a81d747d1dba01a47f939f48c3526d4206` Python sources loaded via `PYTHONPATH`; native extensions were not built locally).\n\n**vLLM-Omni Commit:** `75390448f10322d93b28173fc44ad421ecca32fd`, based on `9ebef4b`.\n\nLocal environment: macOS / Apple M5, Python 3.12.14, PyTorch 2.13.0, Transformers 5.14.1, Diffusers 0.40.0.

loading.\n+Checkpoint-to-engine name mapping is tracked in [#8001](https://github.com/vllm-project/vllm-omni/issues/8001);\n+until it is available, adapter keys must resolve to supported engine

`DIST-数字字母` 是本页可审计规则 ID。connector backend 的选择和端口分配见\n[Distributed architecture](architecture.md) 与 [connector pitfalls](connector-pitfalls.md)。\n\n## DIST-1a — TP KV receive 必须做全 rank 一致的成功/放弃决定\n\n- 触发：纯 TP stage 接收 KV、CFG companion 参与 KV transfer，或 connector receive\n 只在部分 rank 得到 state。\n- 强制：只在 TP process group 内交换 receive state；任一 rank 发现 metadata、shape 或\n payload 不一致时，所有 rank 都走同一个 no-KV fallback，不能让部分 rank 继续 collective。\n- 禁止：用本地 `if` 丢掉 KV 后仍让其他 rank进入 receive；使用 global world group 代替\n stage 的 TP group；把 companion 当成普通 stage-0-final request 静默跳过。\n- 验收：模拟单 rank divergence，断言所有 TP rank 都放弃本次 KV 并保持后续 collective\n 可继续；覆盖普通和 CFG companion 角色。\n\n## DIST-1b — chunk transfer 要区分 upstream exhaustion 与本 stage 完成\n\n- 触发：async-chunk/full-payload connector 传递空 segment、最后一个 chunk 或\n `WAITING_FOR_CHUNK`/active-window 状态。\n- 强制：保留空 segment 的边界语义，区分 upstream 已耗尽和当前 stage 已生成完成；收到\n 后续 chunk 时刷新 prefill/request state，并让 active-window admission 继续推进。\n- 禁止：把空 segment 当作完成信号；用本 stage 的 generation completion 终止上游；在\n connector 没有新数据时无限占用 active window 或静默丢掉 terminal update。\n- 验收：覆盖非空→空→非空、upstream exhaustion、stage completion、重复 terminal\n update 和窗口恢复；首批测试看 `test_chunk_transfer_adapter.py`。\n\n## DIST-1b1 — per-segment adaptive controller 不得越过 connector lifecycle\n\n- 触发：Qwen3-TTS adaptive chunk、resumable segment finish，或 transfer adapter/local runner cleanup 修改。\n- 强制：controller 可按 request 持有，但 `is_segment_finished` 与 request cleanup 均必须清除；下一段从 chunk 0 重新建立 EWMA、emitted ledger、playback cursor 与 telemetry。request-global connector continuity key 不能延长 controller 生命周期。\n- 验收：normal finish、segment finish、abort cleanup 与 empty terminal payload 都断言 state 不残留；覆盖 `OmniChunkTransferAdapter` 和 `OmniConnectorModelRunnerMixin`。^[PR #6001]\n\n## DIST-1c — payload connector 按 edge 所有权创建且不与 KV manager 捆绑\n\n- 触发：修改 AR/DiT 解耦、stage connector role、`custom_process_next_stage_input_func`、\n runner connector 初始化或 KV-only edge。\n- 强制：receiver/非 sender 即使无 downstream hook 也创建 payload connector；sender 只在\n `custom_process_next_stage_input_func` 是非空字符串时创建，空值或非字符串都表示\n KV manager 独自拥有该 edge。KV manager 与 payload connector 必须独立初始化和关闭。\n- 禁止：不得只因已配 connector/role 就创建 payload transport；不得从“无 outgoing\n hook”推导 receiver 也不需要 connector；不得用 consumer-side hook 反推 sender 所有权。\n- 验收：参数化锁定 sender+空/非字符串→不创建、sender+非空字符串→创建、\n receiver/非 sender+无 hook→创建，并覆盖安全 shutdown。Bagel/Hunyuan KV-only 和\n Qwen3-Omni/MiniCPM-o payload 路径各做真实拓扑 smoke。该矩阵不证明 issue #5595 中独立的\n shutdown/orphan 问题已解决。 ^[PR #5744]\n\n## DIST-1d — async-chunk 发送失败必须保留内部请求身份并可观测\n\n- 触发：async-chunk sender 的队列任务被 `popleft()` 后发送抛异常，或 connector 返回失败但不抛异常。\n- 强制：从 task 内的 `request.request_id` 取得 scheduler 使用的内部请求 ID，在发送线程以锁保护的 ledger 中按请求记录首次失败原因；scheduler sweep 时原子 drain 并分别记录仍存活与已离开 scheduler 的请求。\n- 禁止：读取不存在的 `task[\"request_id\"]`；用 `external_req_id` 代替 `self.requests` 的内部 key；发送失败后静默丢弃，或把已完成/已 abort 请求误当作仍可调度请求。\n- 验收：覆盖发送抛异常、`connector.put` 返回 `False`、内部/外部 ID 不同、同一请求多次失败、并发 record/drain，以及请求在 sweep 前后离开 scheduler；日志必须包含正确 request ID 和失败原因，且 ledger 只被消费一次。^[PR #6033]\n\n## DIST-1e — chunk connector 仅按隐藏队列所有权恢复状态并幂等回收 receiver\n\n- 触发：`OmniChunkTransferAdapter.finish_requests` 处理 resumable 请求的 `FINISHED_STOPPED` segment，且请求可能停在 `waiting_for_chunk_waiting_requests`、`waiting_for_chunk_running_requests` 或 `_held_non_active` 中。\n- 强制：只在 connector 隐藏队列实际持有请求时恢复 `requests_origin_status`；对每个目标统一调用幂等的 `cleanup_receiver`，清理 active stream、ready/exhausted/finished/cancelled/waiting 状态，并移除 chunk 等待队列中的已完成请求；请求已回到 scheduler 可见队列后不得再使用过期 origin status 覆盖当前状态。\n- 禁止：仅凭 `requests_origin_status` 存在就恢复状态；把 resumable `FINISHED_STOPPED` 当作普通 finished 请求而跳过 connector 回收；分散复制部分 receiver 清理逻辑导致重复释放或残留 active-stream 占用；用无关请求的队列状态扩大清理范围。\n- 验收：覆盖 connector 隐藏持有、scheduler `running`/`waiting`/`skipped_waiting` 持有、无 connector 所有权及 stale origin；断言隐藏队列、origin ledger、active streams 和 receiver 状态在重复 finish 后仍为空且 active-window 可被新请求重新占用。^[PR #6360]\n\n## DIST-1f — Code2Wav 快照替换必须显式标记并保持终端就绪\n\n- 触发：async-chunk connector 收到 generation runtime payload、终端 chunk 或重复 terminal boundary。\n- 强制：只有 producer 显式设置 `replace_runtime_additional_information=True` 才全量替换；Code2Wav 的空 replacement 必须同时带 `is_segment_finished=True` 以标记就绪；替换时删除旧 `codes.audio`，但保留当前 snapshot 的 `codes.ref` 等 sibling 字段。\n- 禁止：把未标记的 generation/diffusion payload 改成替换语义；把 control-only boundary 写成未就绪的空更新；跨 segment merge/replay 旧 terminal audio。\n- 验收：覆盖标记/未标记、audio+ref、空 replacement 和重复 terminal；断言新 prompt、finished/ready 状态正确，旧 audio 不会进入下一次 Code2Wav。 ^[PR #6406]\n\n## DIST-1g — 异步 processor 任务必须在入队时冻结边界状态\n\n- 触发：`OmniChunkTransferAdapter.save_async` 向 custom next-stage processor 入队，且 producer request 会在 worker 发送前继续被 streaming update 原地修改。\n- 强制：只为 custom processor shallow-copy request，并递归复制其可变容器输入（additional information、prompt/token lists）；tensor leaves 保持共享。每个 queued segment boundary 在入队时移除 `requests_num_chunks_sent` chunk-progress watermark，使下一个 segment 能从 chunk 0 建立自己的 watermark；这不重置 `_segment_generation` gate，后台发送旧 task 也不得清除新 segment 的 watermark。^[PR #6834]\n- 禁止：给无 hook 的直通路径增加 request snapshot/copy；让 queued task 读取后来 mutation 的 token、metadata 或 output history；在后台 terminal cleanup 无条件删除可能已属于下一 segment 的 watermark。\n- 验收：old/new segment 在 background flush 前交错时，新 watermark 保持；连续入队后各 processor 观察各自 admission-time request snapshot；无 custom processor 时 task 仍引用原 request。^[PR #6021]\n\n## DIST-1h — abort 不能让旧 sender generation 复活\n\n- 触发：async-chunk sender 在 background save/connector put 期间 abort，且 external request ID 可复用。\n- 强制：queued task 与其 sender generation token 绑定；abort 取消 token，旧 task 在 put 前后均须拒绝更新 state，in-flight task 在 finally 中回收。sender-state lock 只保护 token/state transition，不能包住 payload construction 或 connector I/O。\n- 禁止：`cleanup_sender` 清空 map 后让 pending save 用默认 chunk counter 写回旧 chunk 0；让 scheduler thread 等待 connector I/O；把同一 external ID 的新 generation 误当作旧 task 的 cleanup target。\n- 验收：覆盖 pending/in-flight abort、stale put completion、ID reuse 和普通 async-chunk transport。^[PR #6089]\n\n## DIST-1i — receiver registration 必须隔离旧 poll 与新 request generation\n\n- 触发：async-chunk receiver 注册/清理与 `connector.get()` 并发、同一 internal request ID 恢复或复用，\n 或已消费 payload 需在 scheduler thread 才能安全修改 prompt。\n- 强制：每次 receiver registration 持有独立 identity entry；`connector.get()` 可在锁外阻塞，但结果\n commit 必须在 receiver-state lock 下确认当前 map 仍指向同一 entry。cleanup 是 commit barrier：旧\n queued/in-flight poll 的迟到结果只能丢弃，不能重建已删除或新 generation 的 prompt/window state。\n AR payload 先冻结为 pending update，再由 scheduler thread 用当前 live request 应用；contract error\n 进入一次性 receive-failure ledger，不得重取已消费 chunk。\n- 禁止：只按可复用 request-id 判断 poll 仍有效；在 I/O 期间持有 scheduler-facing lock；让旧\n terminal cleanup 清掉新 registration；使用被移出 scheduler 的 fallback request 应用 pending mutation。\n- 验收：覆盖 cleanup-during-get、same-ID re-registration、late success/error、重复 register/cleanup、\n scheduler live-ID replacement 与 invalid payload ledger drain；证明旧 entry 不影响新 request。^[PR #6626]\n\n## DIST-1j — sender dedup watermark 必须按 generation/segment 限定\n\n- 触发：async-chunk sender dedup、segment terminal task、background cleanup 或同 request ID 的\n streaming segment replacement。\n- 强制：`save_async` 将 request 的 segment generation 冻结进 queued task；小于当前 generation 的\n late save 必须拒绝。terminal 必须清除 chunk-progress counter；仅当 request\n `._omni_segment_generation is not None` 才把 expected generation 推进 `+1`，否则保持 current\n generation，使 counter-less follow-up 仍以 current/0 enqueue。chunk watermark 只负责同段 progress\n dedup，generation gate 负责跨段 stale fencing；request 最终 cleanup 同时回收 generation 和 chunk state。\n- 禁止：只按裸 request ID 判断 late task 有效；让旧 terminal boundary 因旧 chunk count 被误拒；\n background completion 无条件删除下一段 watermark；把未 ACK 的 serving response snapshot描述成\n 此 sender generation 已给出有界 retention。\n- 验收：覆盖 counter-bearing terminal `+1` fencing 与 counter-less terminal hold/current-0 follow-up、\n counter clear、late old save 和普通 dedup/preemption。该变更不修复已有 stuck ID 或 abort 行为。^[PR #6529] ^[PR #6834]\n\n## DIST-2a — diffusion EP group 必须满足运行中 MoE backend 的 communicator 合同\n\n- 触发：上游 MoE factory/oracle 或 `init_model_parallel_group` 增加 all-to-all manager 要求。\n- 强制：EP group 在运行版本支持 `use_all2all` 时显式启用；兼容旧版本用签名能力检测，不能按版本\n 字符串猜测。非 EP group 保持原参数，避免扩大 communicator 行为。\n- 禁止：创建普通 device communicator 后等 weight load 才触发 manager assert；向不支持该 kwarg\n 的旧 vLLM 无条件传参；把 TP/EP 配置存在当作 manager 已初始化。\n- 验收：mock 新旧签名分别断言 EP 转发/旧版省略，普通 group 不启用；目标环境用真实 MoE DiT\n TP+EP smoke 验证 manager 非空。^[PR #5976]\n\n## DIST-3a — Omni 输出序列化必须按扁平 dataclass 合同兼容旧线格式\n\n- 触发：修改 `OmniMsgpackEncoder`/`OmniMsgpackDecoder`、`OmniRequestOutput` 字段或跨 stage 输出 wire format。\n- 强制：当前 `OmniRequestOutput` 按其 dataclass 字段重建，不能落入基类 `RequestOutput` 的动态属性编码路径；decoder 只构造已知字段，并在旧 wire format 含嵌套 `request_output` 时完成一次向扁平对象的内容合并。基类 `RequestOutput` 的字段集合必须跟随 pinned upstream 合同。\n- 禁止：让 subclass 走基类序列化而丢失 diffusion/stage 字段或形成递归；不得把未知 key 直接传给 `RequestOutput`/dataclass 构造器；upstream 已移除的 `multi_modal_placeholders` 不得仅为旧动态属性重新作为当前字段恢复。\n- 验收：msgpack round-trip 分别覆盖 pipeline 文本输出和 diffusion 图像输出，保持 request metadata、prompt、token、outputs、finished、stage 字段及图像内容；旧嵌套 wire payload 能解码为扁平对象，编码不递归且解码后的字段可被直接消费。^[PR #5146]\n\n## DIST-1k — Mooncake TCP write completion 必须表示目的端已应用\n\n- 触发：升级 `mooncake-transfer-engine`、修改 TCP `batch_transfer_sync_write`/completion 语义，或让零拷贝 consumer 在 write completion 后立即读取 destination buffer。\n- 强制：CUDA Mooncake 依赖必须钉在包含 acknowledged TCP writes 的版本（`0.3.12` 起）；`batch_transfer_sync_write` 返回成功后，destination 内存必须已更新到可读状态，不能只表示本地 send 入队。回归必须在 receiver 被挂起时证明 completion 不会提前返回，恢复后再断言目的端字节一致。\n- 禁止：降级到无 ACK 的 TCP 实现却不更新测试合同；把 RDMA 路径的 completion 语义外推到 TCP；或在 completion 前启动依赖 destination 内容的零拷贝消费。\n- 验收：强制 TCP 的挂起-恢复测试覆盖「停止期间不完成、恢复后成功且字节匹配」；依赖声明与该测试同步变更。^[PR #7136]\n\n## DIST-1l — parked async-chunk sender 收到终态 update 必须先投递 terminal chunk\n\n- 触发：修改 `OmniSchedulerMixin.add_request`、`OmniChunkTransferAdapter.save_async` / sender cleanup，或 realtime/async-chunk 在 `WAITING_FOR_STREAMING_REQ` 上的终态竞态。\n- 强制：当终态 update（`resumable=False`）落在已 parked 且 `has_active_sender` 的 session 上时，不得只走 upstream 的本地 `FINISHED_ABORTED`。必须先 `force_request_finished` 入队携带 `finished` 的 request-terminal chunk（必要时推进 `_omni_segment_generation` 以通过 dedup），再本地 finish。`terminal_pending` 必须挡住丢弃该 chunk 的 cleanup，直到 connector 接受。\n- 禁止：假设 orchestrator 的一次性 StreamingUpdate 对下游 receiver 足够；在 `finish_requests` 之后才尝试 enqueue terminal；让 cleanup 在 terminal 上线前回收 generation，导致下游卡在 `WAITING_FOR_CHUNK` 直至输入超时。\n- 验收：覆盖 parked+active-sender 终态、非 sender/非 parked 回退、`force_request_finished` 顺序、terminal_pending 与 deferred cleanup；证明下游经 payload `finished` 结束，而不是仅靠 600s stall。^[PR #6889]\n\n## DIST-1l2 — NIXL connector 超时后必须保留 native 资源直到终端态\n\n- 触发：新增/修改 `NixlConnector`、NIXL READ、ZMQ claim/`XFER_DONE`、lease 或 receive timeout。\n- 强制：NIXL 无远端 READ 取消时，超时/放弃后仍保留 buffer、registration、descriptor、transfer handle 与 remote agent，直到 native 终端态；`close()` 等待后再释放。源 registration 有界 lease（`lease_seconds` / `VLLM_OMNI_NIXL_LEASE_S`）并由 reaper 回收。跨 stage 请求须把 producer endpoint/`payload_sender_info` 经 scheduler handle 传到 consumer。\n- 禁止：超时后立刻 deregister 或丢弃仍可能被 DMA 写入的内存；把 vLLM P/D block-table NIXL 接口当作 Omni 任意 payload connector；依赖未声明的固定 `zmq_port` 却不经 resolver。\n- 验收：覆盖超时保留、lease 回收、metadata claim/ack，以及 `OmniChunkRecvHandle.payload_sender_info` 贯通；缺 NIXL 依赖时 lazy import 为 None。^[PR #6093]\n\n## DIST-1l3 — NIXL 所有权测试必须用 reliable_claim_queries 隔离 claim 查询\n\n- 触发：修改 NIXL connector 中断言 terminal 或 deferred read ownership、`_wait_for_transfer` 或 `entered.wait` 的测试，或改变 metadata claim 的获取方式。\n- 强制：这类所有权用例必须挂上 `reliable_claim_queries`。fixture 仍覆盖 metadata 解析、wire 编解码、claim 生成和 producer claim 状态机，但不得用一次有界（10 ms）真实 ZMQ query 取得 claim。真实 ZMQ discovery 只由同模块 handshake 测试覆盖。\n- 禁止：让所有权断言依赖 CI 下可能超时的短 query，使 `consumer.get()` 在进入 transfer wait 前返回；或放宽 `entered.wait` 来掩盖未挂 fixture。\n- 验收：`direct` 与 `done`/`error`/`timeout`/`unknown` 在 fixture 下重复通过；所有权用例源码不再走有界 claim query。handshake 测试仍覆盖真实 ZMQ discovery。^[PR #7870]\n\n## DIST-1l4 — 原生 Mooncake AR→DiT KV 必须关 async_chunk 并按物理页序释放\n\n- 触发：部署或修改 `kv_transfer_config`/`MooncakeConnector`、AR→DiT 原生 KV handoff、`OmniARScheduler` 的 block free，或与 legacy `OmniKVTransferManager` 并存的路径。\n- 强制：存在 stage `kv_transfer_config` 时必须 `async_chunk=False`。原生路径由 scheduler 拥有 diffusion KV 页；connector 失败 fail-close diffusion engine 后再拆页。非 caching P/D 池释放时按递增 `block_id` 归还，便于相邻页合并；deferred free 存逆序以匹配 vLLM drain。原生 transfer 边界用已确认 computed tokens，排除 async output placeholders；需要时短暂改写 request status/token 计数并在 `finally` 恢复。\n- 禁止：`async_chunk=True` 搭配原生 KV transfer；把 eviction-priority free 顺序当成无缓存池的物理布局；用含 placeholder 的 token 计数作为 transfer 边界；connector 失败后仍继续拆页当成功。\n- 验收：配置拒绝 async_chunk+kv_transfer；物理序 free；confirmed-token transfer 边界；失败 fail-close。^[PR #7166]\n" + }, + "head": { +

的选择和端口分配见\n[Distributed architecture](architecture.md) 与 [connector pitfalls](connector-pitfalls.md)。\n\n## DIST-1a — TP KV receive 必须做全 rank 一致的成功/放弃决定\n\n- 触发：纯 TP stage 接收 KV、CFG companion 参与 KV transfer，或 connector receive\n 只在部分 rank 得到 state。\n- 强制：只在 TP process group 内交换 receive state；任一 rank 发现 metadata、shape 或\n payload 不一致时，所有 rank 都走同一个 no-KV fallback，不能让部分 rank 继续 collective。\n- 禁止：用本地 `if` 丢掉 KV 后仍让其他 rank进入 receive；使用 global world group 代替\n stage 的 TP group；把 companion 当成普通 stage-0-final request 静默跳过。\n- 验收：模拟单 rank divergence，断言所有 TP rank 都放弃本次 KV 并保持后续 collective\n 可继续；覆盖普通和 CFG companion 角色。\n\n## DIST-1b — chunk transfer 要区分 upstream exhaustion 与本 stage 完成\n\n- 触发：async-chunk/full-payload connector 传递空 segment、最后一个 chunk 或\n `WAITING_FOR_CHUNK`/active-window 状态。\n- 强制：保留空 segment 的边界语义，区分 upstream 已耗尽和当前 stage 已生成完成；收到\n 后续 chunk 时刷新 prefill/request state，并让 active-window admission 继续推进。\n- 禁止：把空 segment 当作完成信号；用本 stage 的 generation completion 终止上游；在\n connector 没有新数据时无限占用 active window 或静默丢掉 terminal update。\n- 验收：覆盖非空→空→非空、upstream exhaustion、stage completion、重复 terminal\n update 和窗口恢复；首批测试看 `test_chunk_transfer_adapter.py`。\n\n## DIST-1b1 — per-segment adaptive controller 不得越过 connector lifecycle\n\n- 触发：Qwen3-TTS adaptive chunk、resumable segment finish，或 transfer adapter/local runner cleanup 修改。\n- 强制：controller 可按 request 持有，但 `is_segment_finished` 与 request cleanup 均必须清除；下一段从 chunk 0 重新建立 EWMA、emitted ledger、playback cursor 与 telemetry。request-global connector continuity key 不能延长 controller 生命周期。\n- 验收：normal finish、segment finish、abort cleanup 与 empty terminal payload 都断言 state 不残留；覆盖 `OmniChunkTransferAdapter` 和 `OmniConnectorModelRunnerMixin`。^[PR #6001]\n\n## DIST-1c — payload connector 按 edge 所有权创建且不与 KV manager 捆绑\n\n- 触发：修改 AR/DiT 解耦、stage connector role、`custom_process_next_stage_input_func`、\n runner connector 初始化或 KV-only edge。\n- 强制：receiver/非 sender 即使无 downstream hook 也创建 payload connector；sender 只在\n `custom_process_next_stage_input_func` 是非空字符串时创建，空值或非字符串都表示\n KV manager 独自拥有该 edge。KV manager 与 payload connector 必须独立初始化和关闭。\n- 禁止：不得只因已配 connector/role 就创建 payload transport；不得从“无 outgoing\n hook”推导 receiver 也不需要 connector；不得用 consumer-side hook 反推 sender 所有权。\n- 验收：参数化锁定 sender+空/非字符串→不创建、sender+非空字符串→创建、\n receiver/非 sender+无 hook→创建，并覆盖安全 shutdown。Bagel/Hunyuan KV-only 和\n Qwen3-Omni/MiniCPM-o payload 路径各做真实拓扑 smoke。该矩阵不证明 issue #5595 中独立的\n shutdown/orphan 问题已解决。 ^[PR #5744]\n\n## DIST-1d — async-chunk 发送失败必须保留内部请求身份并可观测\n\n- 触发：async-chunk sender 的队列任务被 `popleft()` 后发送抛异常，或 connector 返回失败但不抛异常。\n- 强制：从 task 内的 `request.request_id` 取得 scheduler 使用的内部请求 ID，在发送线程以锁保护的 ledger 中按请求记录首次失败原因；scheduler sweep 时原子 drain 并分别记录仍存活与已离开 scheduler 的请求。\n- 禁止：读取不存在的 `task[\"request_id\"]`；用 `external_req_id` 代替 `self.requests` 的内部 key；发送失败后静默丢弃，或把已完成/已 abort 请求误当作仍可调度请求。\n- 验收：覆盖发送抛异常、`connector.put` 返回 `False`、内部/外部 ID 不同、同一请求多次失败、并发 record/drain，以及请求在 sweep 前后离开 scheduler；日志必须包含正确 request ID 和失败原因，且 ledger 只被消费一次。^[PR #6033]\n\n## DIST-1e — chunk connector 仅按隐藏队列所有权恢复状态并幂等回收 receiver\n\n- 触发：`OmniChunkTransferAdapter.finish_requests` 处理 resumable 请求的 `FINISHED_STOPPED` segment，且请求可能停在 `waiting_for_chunk_waiting_requests`、`waiting_for_chunk_running_requests` 或 `_held_non_active` 中。\n- 强制：只在 connector 隐藏队列实际持有请求时恢复 `requests_origin_status`；对每个目标统一调用幂等的 `cleanup_receiver`，清理 active stream、ready/exhausted/finished/cancelled/waiting 状态，并移除 chunk 等待队列中的已完成请求；请求已回到 scheduler 可见队列后不得再使用过期 origin status 覆盖当前状态。\n- 禁止：仅凭 `requests_origin_status` 存在就恢复状态；把 resumable `FINISHED_STOPPED` 当作普通 finished 请求而跳过 connector 回收；分散复制部分 receiver 清理逻辑导致重复释放或残留 active-stream 占用；用无关请求的队列状态扩大清理范围。\n- 验收：覆盖 connector 隐藏持有、scheduler `running`/`waiting`/`skipped_waiting` 持有、无 connector 所有权及 stale origin；断言隐藏队列、origin ledger、active streams 和 receiver 状态在重复 finish 后仍为空且 active-window 可被新请求重新占用。^[PR #6360]\n\n## DIST-1f — Code2Wav 快照替换必须显式标记并保持终端就绪\n\n- 触发：async-chunk connector 收到 generation runtime payload、终端 chunk 或重复 terminal boundary。\n- 强制：只有 producer 显式设置 `replace_runtime_additional_information=True` 才全量替换；Code2Wav 的空 replacement 必须同时带 `is_segment_finished=True` 以标记就绪；替换时删除旧 `codes.audio`，但保留当前 snapshot 的 `codes.ref` 等 sibling 字段。\n- 禁止：把未标记的 generation/diffusion payload 改成替换语义；把 control-only boundary 写成未就绪的空更新；跨 segment merge/replay 旧 terminal audio。\n- 验收：覆盖标记/未标记、audio+ref、空 replacement 和重复 terminal；断言新 prompt、finished/ready 状态正确，旧 audio 不会进入下一次 Code2Wav。 ^[PR #6406]\n\n## DIST-1g — 异步 processor 任务必须在入队时冻结边界状态\n\n- 触发：`OmniChunkTransferAdapter.save_async` 向 custom next-stage processor 入队，且 producer request 会在 worker 发送前继续被 streaming update 原地修改。\n- 强制：只为 custom processor shallow-copy request，并递归复制其可变容器输入（additional information、prompt/token lists）；tensor leaves 保持共享。每个 queued segment boundary 在入队时移除 `requests_num_chunks_sent` chunk-progress watermark，使下一个 segment 能从 chunk 0 建立自己的 watermark；这不重置 `_segment_generation` gate，后台发送旧 task 也不得清除新 segment 的 watermark。^[PR #6834]\n- 禁止：给无 hook 的直通路径增加 request snapshot/copy；让 queued task 读取后来 mutation 的 token、metadata 或 output history；在后台 terminal cleanup 无条件删除可能已属于下一 segment 的 watermark。\n- 验收：old/new segment 在 background flush 前交错时，新 watermark 保持；连续入队后各 processor 观察各自 admission-time request snapshot；无 custom processor 时 task 仍引用原 request。^[PR #6021]\n\n## DIST-1h — abort 不能让旧 sender generation 复活\n\n- 触发：async-chunk sender 在 background save/connector put 期间 abort，且 external request ID 可复用。\n- 强制：queued task 与其 sender generation token 绑定；abort 取消 token，旧 task 在 put 前后均须拒绝更新 state，in-flight task 在 finally 中回收。sender-state lock 只保护 token/state transition，不能包住 payload construction 或 connector I/O。\n- 禁止：`cleanup_sender` 清空 map 后让 pending save 用默认 chunk counter 写回旧 chunk 0；让 scheduler thread 等待 connector I/O；把同一 external ID 的新 generation 误当作旧 task 的 cleanup target。\n- 验收：覆盖 pending/in-flight abort、stale put completion、ID reuse 和普通 async-chunk transport。^[PR #6089]\n\n## DIST-1i — receiver registration 必须隔离旧 poll 与新 request generation\n\n- 触发：async-chunk receiver 注册/清理与 `connector.get()` 并发、同一 internal request ID 恢复或复用，\n 或已消费 payload 需在 scheduler thread 才能安全修改 prompt。\n- 强制：每次 receiver registration 持有独立 identity entry；`connector.get()` 可在锁外阻塞，但结果\n commit 必须在 receiver-state lock 下确认当前 map 仍指向同一 entry。cleanup 是 commit barrier：旧\n queued/in-flight poll 的迟到结果只能丢弃，不能重建已删除或新 generation 的 prompt/window state。\n AR payload 先冻结为 pending update，再由 scheduler thread 用当前 live request 应用；contract error\n 进入一次性 receive-failure ledger，不得重取已消费 chunk。\n- 禁止：只按可复用 request-id 判断 poll 仍有效；在 I/O 期间持有 scheduler-facing lock；让旧\n terminal cleanup 清掉新 registration；使用被移出 scheduler 的 fallback request 应用 pending mutation。\n- 验收：覆盖 cleanup-during-get、same-ID re-registration、late success/error、重复 register/cleanup、\n scheduler live-ID replacement 与 invalid payload ledger drain；证明旧 entry 不影响新 request。^[PR #6626]\n\n## DIST-1j — sender dedup watermark 必须按 generation/segment 限定\n\n- 触发：async-chunk sender dedup、segment terminal task、background cleanup 或同 request ID 的\n streaming segment replacement。\n- 强制：`save_async` 将 request 的 segment generation 冻结进 queued task；小于当前 generation 的\n late save 必须拒绝。terminal 必须清除 chunk-progress counter；仅当 request\n `._omni_segment_generation is not None` 才把 expected generation 推进 `+1`，否则保持 current\n generation，使 counter-less follow-up 仍以 current/0 enqueue。chunk watermark 只负责同段 progress\n dedup，generation gate 负责跨段 stale fencing；request 最终 cleanup 同时回收 generation 和 chunk state。\n- 禁止：只按裸 request ID 判断 late task 有效；让旧 terminal boundary 因旧 chunk count 被误拒；\n background completion 无条件删除下一段 watermark；把未 ACK 的 serving response snapshot描述成\n 此 sender generation 已给出有界 retention。\n- 验收：覆盖 counter-bearing terminal `+1` fencing 与 counter-less terminal hold/current-0 follow-up、\n counter clear、late old save 和普通 dedup/preemption。该变更不修复已有 stuck ID 或 abort 行为。^[PR #6529] ^[PR #6834]\n\n## DIST-2a — diffusion EP group 必须满足运行中 MoE backend 的 communicator 合同\n\n- 触发：上游 MoE factory/oracle 或 `init_model_parallel_group` 增加 all-to-all manager 要求。\n- 强制：EP group 在运行版本支持 `use_all2all` 时显式启用；兼容旧版本用签名能力检测，不能按版本\n 字符串猜测。非 EP group 保持原参数，避免扩大 communicator 行为。\n- 禁止：创建普通 device communicator 后等 weight load 才触发 manager assert；向不支持该 kwarg\n 的旧 vLLM 无条件传参；把 TP/EP 配置存在当作 manager 已初始化。\n- 验收：mock 新旧签名分别断言 EP 转发/旧版省略，普通 group 不启用；目标环境用真实 MoE DiT\n TP+EP smoke 验证 manager 非空。^[PR #5976]\n\n## DIST-3a — Omni 输出序列化必须按扁平 dataclass 合同兼容旧线格式\n\n- 触发：修改 `OmniMsgpackEncoder`/`OmniMsgpackDecoder`、`OmniRequestOutput` 字段或跨 stage 输出 wire format。\n- 强制：当前 `OmniRequestOutput` 按其 dataclass 字段重建，不能落入基类 `RequestOutput` 的动态属性编码路径；decoder 只构造已知字段，并在旧 wire format 含嵌套 `request_output` 时完成一次向扁平对象的内容合并。基类 `RequestOutput` 的字段集合必须跟随 pinned upstream 合同。\n- 禁止：让 subclass 走基类序列化而丢失 diffusion/stage 字段或形成递归；不得把未知 key 直接传给 `RequestOutput`/dataclass 构造器；upstream 已移除的 `multi_modal_placeholders` 不得仅为旧动态属性重新作为当前字段恢复。\n- 验收：msgpack round-trip 分别覆盖 pipeline 文本输出和 diffusion 图像输出，保持 request metadata、prompt、token、outputs、finished、stage 字段及图像内容；旧嵌套 wire payload 能解码为扁平对象，编码不递归且解码后的字段可被直接消费。^[PR #5146]\n\n## DIST-1k — Mooncake TCP write completion 必须表示目的端已应用\n\n- 触发：升级 `mooncake-transfer-engine`、修改 TCP `batch_transfer_sync_write`/completion 语义，或让零拷贝 consumer 在 write completion 后立即读取 destination buffer。\n- 强制：CUDA Mooncake 依赖必须钉在包含 acknowledged TCP writes 的版本（`0.3.12` 起）；`batch_transfer_sync_write` 返回成功后，destination 内存必须已更新到可读状态，不能只表示本地 send 入队。回归必须在 receiver 被挂起时证明 completion 不会提前返回，恢复后再断言目的端字节一致。\n- 禁止：降级到无 ACK 的 TCP 实现却不更新测试合同；把 RDMA 路径的 completion 语义外推到 TCP；或在 completion 前启动依赖 destination 内容的零拷贝消费。\n- 验收：强制 TCP 的挂起-恢复测试覆盖「停止期间不完成、恢复后成功且字节匹配」；依赖声明与该测试同步变更。^[PR #7136]\n\n## DIST-1l — parked async-chunk sender 收到终态 update 必须先投递 terminal chunk\n\n- 触发：修改 `OmniSchedulerMixin.add_request`、`OmniChunkTransferAdapter.save_async` / sender cleanup，或 realtime/async-chunk 在 `WAITING_FOR_STREAMING_REQ` 上的终态竞态。\n- 强制：当终态 update（`resumable=False`）落在已 parked 且 `has_active_sender` 的 session 上时，不得只走 upstream 的本地 `FINISHED_ABORTED`。必须先 `force_request_finished` 入队携带 `finished` 的 request-terminal chunk（必要时推进 `_omni_segment_generation` 以通过 dedup），再本地 finish。`terminal_pending` 必须挡住丢弃该 chunk 的 cleanup，直到 connector 接受。\n- 禁止：假设 orchestrator 的一次性 StreamingUpdate 对下游 receiver 足够；在 `finish_requests` 之后才尝试 enqueue terminal；让 cleanup 在 terminal 上线前回收 generation，导致下游卡在 `WAITING_FOR_CHUNK` 直至输入超时。\n- 验收：覆盖 parked+active-sender 终态、非 sender/非 parked 回退、`force_request_finished` 顺序、terminal_pending 与 deferred cleanup；证明下游经 payload `finished` 结束，而不是仅靠 600s stall。^[PR #6889]\n\n## DIST-1l2 — NIXL connector 超时后必须保留 native 资源直到终端态\n\n- 触发：新增/修改 `NixlConnector`、NIXL READ、ZMQ claim/`XFER_DONE`、lease 或 receive timeout。\n- 强制：NIXL 无远端 READ 取消时，超时/放弃后仍保留 buffer、registration、descriptor、transfer handle 与 remote agent，直到 native 终端态；`close()` 等待后再释放。源 registration 有界 lease（`lease_seconds` / `VLLM_OMNI_NIXL_LEASE_S`）并由 reaper 回收。跨 stage 请求须把 producer endpoint/`payload_sender_info` 经 scheduler handle 传到 consumer。\n- 禁止：超时后立刻 deregister 或丢弃仍可能被 DMA 写入的内存；把 vLLM P/D block-table NIXL 接口当作 Omni 任意 payload connector；依赖未声明的固定 `zmq_port` 却不经 resolver。\n- 验收：覆盖超时保留、lease 回收、metadata claim/ack，以及 `OmniChunkRecvHandle.payload_sender_info` 贯通；缺 NIXL 依赖时 lazy import 为 None。^[PR #6093]\n\n## DIST-1l3 — NIXL 所有权测试必须用 reliable_claim_queries 隔离 claim 查询\n\n- 触发：修改 NIXL connector 中断言 terminal 或 deferred read ownership、`_wait_for_transfer` 或 `entered.wait` 的测试，或改变 metadata claim 的获取方式。\n- 强制：这类所有权用例必须挂上 `reliable_claim_queries`。fixture 仍覆盖 metadata 解析、wire 编解码、claim 生成和 producer claim 状态机，但不得用一次有界（10 ms）真实 ZMQ query 取得 claim。真实 ZMQ discovery 只由同模块 handshake 测试覆盖。\n- 禁止：让所有权断言依赖 CI 下可能超时的短 query，使 `consumer.get()` 在进入 transfer wait 前返回；或放宽 `entered.wait` 来掩盖未挂 fixture。\n- 验收：`direct` 与 `done`/`error`/`timeout`/`unknown` 在 fixture 下重复通过；所有权用例源码不再走有界 claim query。handshake 测试仍覆盖真实 ZMQ discovery。^[PR #7870]\n\n## DIST-1l4 — 原生 Mooncake AR→DiT KV 必须关 async_chunk 并按物理页序释放\n\n- 触发：部署或修改 `kv_transfer_config`/`MooncakeConnector`、AR→DiT 原生 KV handoff、`OmniARScheduler` 的 block free，或与 legacy `OmniKVTransferManager` 并存的路径。\n- 强制：存在 stage `kv_transfer_config` 时必须 `async_chunk=False`。原生路径由 scheduler 拥有 diffusion KV 页；connector 失败 fail-close diffusion engine 后再拆页。非 caching P/D 池释放时按递增 `block_id` 归还，便于相邻页合并；deferred free 存逆序以匹配 vLLM drain。原生 transfer 边界用已确认 computed tokens，排除 async output placeholders；需要时短暂改写 request status/token 计数并在 `finally` 恢复。\n- 禁止：`async_chunk=True` 搭配原生 KV transfer；把 eviction-priority free 顺序当成无缓存池的物理布局；用含 placeholder 的 token 计数作为 transfer 边界；connector 失败后仍继续拆页当成功。\n- 验收：配置拒绝 async_chunk+kv_transfer；物理序 free；confirmed-token transfer 边界；失败 fail-close。^[PR #7166]\n\n## DIST-1m — SHM producer 只能按 put 的精确 key 回收，并有界 reap 跨进程已消费段\n\n- 触发：修改 `SharedMemoryConnector` 的 `_pending_keys` / `cleanup` / `close` / `reap_consumed`，chunk adapter abort 后的 sender 清理，或 lock-file 与 `/dev/shm` 回收。\n- 强制：`cleanup` 只 unlink `put()` 当时登记的精确 key，不得按 request-id 做 `_` 前缀/后缀模糊匹配。receiver 读到 SHM 字节后即可标 consumed 并删 lock file，即使随后 deserialize 失败。producer 在 `put` 与空闲 save loop 上做有界 round-robin `reap_consumed`（丢弃对端已 unlink 的 key）。abort 后在 in-flight 排空再按 adapter 生成的精确 chunk key 入队清理；成功终态 payload 必须留给下游消费，且清理发生在 external-id 复用之前。receiver 用当前 registration identity 拒 stale work，不得堆积 cancellation tombstone。\n- 禁止：用 request-id 子串误删无关 SHM；把已跨进程消费的 key 永远留在 `_pending_keys`；deserialize 失败就留下 lock file；用 underscore-prefix 猜测所有权。\n- 验收：覆盖相似 request id、abort-during-put、external-id 复用、无效 payload 后 lock 消失、consumed-key 回收，以及取消后 `/dev/shm` 与 pending keys 归零。^[PR #8082]\n\n\n" + }, + "evidence": [ + { + "source_reference": "PR #8082", + "title": "[Bugfix] Reclaim aborted chunk SHM and consumed connector state", + "body": "## Purpose\n\nFixes #6352.\n\nCurrent main already fences aborted sender work, but unconsumed SHM and lock files remain after abort. Sender `_pending_keys` also retains keys consumed by a different process, and receiver cancellation tombstones accumulate after requests finish.\n\n- Queue cleanup of exact chunk keys on the existing save thread after in-flight work drains. Preserve successful terminal payloads for downstream consumption and order cleanup before external-ID reuse.\n- Reap consumed producer keys with a bounded round-robin scan, including when the sender is idle.\n- Use existing receiver registration identity to reject stale work without persistent cancellation tombstones. Publish the request-ID mapping inside that same protected path.\n- Remove the lock file after SHM has been consumed even if deserialization fails.\n\nThis carries forward the consumed-SHM lock-file cleanup from #4349 by @gagandhakrey, credited as a co-author. Request ownership is determined by exact keys generated by the adapter; underscore-prefix matching is not used.\n\n## Test Plan\n\n**vLLM Version:** 0.30.0; Python 3.12; torch 2.13.0+cu130; transformers 5.14.1. CPU tests use `CUDA_VISIBLE_DEVICES=\"\"`; model serving uses one NVIDIA H800 80 GB.\n\n**vLLM-Omni Commit:** `4843c857f00979d0169055c05460c067a1a0735f`; based on `cb5f508212befb16b48e5760f3b7508c457d6413`.\n\n```bash\nPYTHONPATH=. CUDA_VISIBLE_DEVICES=\"\" python -m pytest -q \\\n tests/distributed/omni_connectors \\\n -m \"core_model and cpu\" --run-level core_model\n```\n\nCoverage includes real POSIX SHM, similar request IDs, abort during put, external-ID reuse, failed and successful terminal sends, stale receiver registrations, lock cleanup after invalid payloads, and consumed-key reclamation.\n\nServing validation uses `Qwen/Qwen3-TTS-12Hz-0.6B-Base` with the stock Qwen3-TTS deploy configuration and `model_runner: v1`. Async chunk streaming and CUDA graphs remain enabled. After warmup, send four batches of six concurrent `/v1/audio/speech` requests: three complete responses and three client disconnects after the first audio chunk per batch. Then send a completion after cancellations and check `/health`, abort metrics, and `/dev/shm` before shutting the server down.\n\n## Test Result\n\n- Relevant connector suite: 424 passed, 3 skipped, 36 deselected.\n- On unchanged main, 12 new regression cases fail; the successful-terminal and stale-entry controls pass.\n- Separate producer/consumer processes completed 5,000 transfers: 4,285 consumed and 715 deliberately left unread then cancelled. Final pending keys, owned SHM segments and lock files: zero. This is a transport exercise, not a model-serving RSS soak.\n- Model-serving E2E passed: 14 complete responses and 12 first-chunk disconnects; abort counter 12; valid non-silent PCM; successful completion after cancellations and health check.

MRoPE/RMSNorm 路径，或升级会改变 Inductor MRoPE fusion 的 vLLM 版本。\n- 强制：CUDA platform overlay 仅为 Thinker stage 0 设置 `compilation_config.custom_ops: [\"+rotary_embedding\"]`，保持 MRoPE 在 CUDA/Triton custom-op 边界后；Talker/Code2Wav 与 CPU、MUSA、NPU、ROCm、XPU 配置不得继承此 override。\n- 禁止：以全局 `enforce_eager` 取代窄 graph boundary；启用更宽的 Q/K norm-RoPE fusion flag；只检查 YAML 文本，或将 Thinker 数值稳定性外推为全部 Qwen stage/平台。\n- 验收：经 `_apply_platform_overrides → merge_pipeline_deploy` 断言 CUDA 仅 stage 0 有该 custom op、其余 stage/平台均无；固定 seed 下与 eager oracle 的 thinker/talker/codec 离散轨迹必须完全一致，并验证生成 WAV 逐字节一致。相关配置展开见 [Configuration rules](../../components/configuration/rules.md)，家族 topology 见 [architecture](architecture.md)。^[PR #6449]\n\n## QOMNI-1b — Qwen3-Omni 嵌套 stage 的量化名称只能在统一 wrapper 映射一次\n\n- 触发：修改 Qwen3-Omni 的 `SupportsQuant`、`WeightsMapper`、compressed-tensors/AWQ\n ignore/exclude 名称，或 Thinker、Talker、Code2Wav 的嵌套模型构造。\n- 强制：在统一 Qwen3-Omni wrapper 暴露 checkpoint 到最终嵌套模块路径的映射，并先对完整\n quantization config 执行一次映射；`ComponentQuantizationConfig` 必须递归映射每个非空\n component 和 default config。子 stage 检测到该映射后不得再次改写名称，但仍须合并自己的\n `packed_modules_mapping`，供量化 scheme 匹配 fused module。该嵌套 metadata 是 optional：outer-map-once\n marker 已存在时，缺少 attribute 必须 no-op；存在且非空时才 merge，且不得清掉 outer marker。\n- 禁止：只映射一个 component wrapper 而给它标记为已映射；让 Thinker/Talker/Code2Wav 各自\n 重复应用 stage mapper；因修复名称匹配而把 BF16 router/encoder 也纳入量化；或把该构造期\n 映射修复描述成 quantization kernel / inference hot path 变化。\n- 验收：以真实 component-wrapped `CompressedTensorsConfig`（含 `None` component 与 default）\n 断言 `ignore` HF names 映射到最终路径；加载 AWQ checkpoint 时三 stage 都能完成 weight\n loading，且不出现缺模块/参数或 routed-expert quantized-weight 属性错误。CPU regression 还必须覆盖\n missing quant config、outer-mapped Talker-style model 缺 `packed_modules_mapping` 的 no-op、及 present\n mapping merge；这只是 mapping/metadata contract，不是 quant scheme、kernel、quality 或 performance\n evidence。^[PR #5687] ^[PR #6748]\n\n## QOMNI-1c — Instruct 的 thinker-only deploy 必须选择静态 pipeline key\n\n- 触发：修改 Qwen3-Omni 的 pipeline registry、`qwen3_omni_moe_thinking.yaml`，或依赖\n `enable_audio_output` 自动拓扑选择的 serve/config-factory 路径。\n- 强制：需要 Instruct 权重只加载 Thinker 时，deploy YAML 必须显式设\n `pipeline: qwen3_omni_moe_thinker_only`；该 registry key 必须直接绑定静态单 stage\n text→text `PipelineConfig`，不能重新进入由 HF config 决定全三 stage 的\n `qwen3_omni_moe` resolver。没有显式 YAML 的 Captioner/Thinking checkpoint 继续由 resolver\n 自动选择 thinker-only 拓扑。\n- 禁止：把 Instruct 的 `enable_audio_output` 当作 thinker-only 的充分条件；只修改 YAML 而未\n 注册静态 key；或以 key 存在/原始 YAML 替代最终 resolved pipeline 的断言。\n- 验收：分别以 Instruct 和 Thinking/Captioner HF config 经 `StageConfigFactory` 加载该 YAML，\n 断言同一 `qwen3_omni_moe_thinker_only` pipeline、仅一个 Thinker stage 和 text output；同时\n 直接解析该 key，断言其对象身份为 registry 的静态 `PipelineConfig` 而非 resolver 结果。PR\n 只有这类配置单元测试，未提供真实 `vllm serve`、质量、性能或资源证据。^[PR #6284]\n\n## QOMNI-1d — audio encoder TP 必须按 head divisibility 局部回退\n\n- 触发：修改 Qwen3-Omni audio encoder 的 attention/FFN parallel linear、`encoder_attention_heads`，或其 global tensor-parallel 初始化。\n- 强制：以 `encoder_attention_heads % global_tp_size` 判定该 audio-encoder layer 是否可分片。可整除时保持 global TP；不可整除时仅该 encoder layer 的 attention QKV、attention output projection、FC1 和 FC2 都以 `disable_tp=True` 构造，且 local attention head count 按 effective TP=1 计算。\n- 禁止：仅关闭 QKV 或仅修正 `num_local_heads` 而让 output/FFN 仍分片；把这项 fallback 扩大为整个 Qwen3-Omni 模型关闭 TP；或把 PR 的 TP1/2/4/8 手工音频请求、MI350x full-workload throughput 数字归因于该 fallback。\n- 验收：分别覆盖 heads 可被和不可被 global TP 整除的构造，断言四个 linear 的 `disable_tp` 一致、attention local-head count 正确，且 encoder 外的 Thinker/Talker TP 配置未被此条件改写。PR 仅报告手工请求与整体 workload 测量，未给出该局部回退的独立性能或质量证明。^[PR #4322]\n\n## QOMNI-1e — Qwen2.5-Omni code2wav 缺失时必须 soft-fail，不能复活跨 stage 的旧 speech helper\n\n- 触发：修改 Qwen2.5-Omni 的 `generate_audio`、`_codec_to_audio`、`_init_token2wav_model`、weight loading、Talker sampling/logits，或 Thinker/Talker/Code2Wav 的 staged 构造。\n- 强制：`_codec_to_audio` 在 `token2wav` 缺失时必须直接返回 `None`；`_init_token2wav_model` 只能由持有已解析 `hf_model_folder` 的 Token2Wav weight-loading 路径调用；语音生成维持 Thinker → Talker → Code2Wav 的 stage handoff。\n- 禁止：无参数调用 `_init_token2wav_model()`；恢复 `generate_speech` 或 `_convert_to_codec_tokens`；仅 thread `sampling_metadata` 就声称修复旧 helper（其 Talker `compute_logits` 调用仍带已失效的额外参数）；或让单一 wrapper 违反 staged ownership 而同时拥有 Talker 和 Token2Wav。\n- 验收：目标树中不存在两个已删除 helper 或无参数 initializer call；`token2wav is None` 的 `_codec_to_audio` 路径返回 `None` 而非 `TypeError`；Token2Wav load path 仍向 initializer 传入解析后的 HF directory。PR 未新增测试或 E2E，故这些是静态/call-site 合同，不构成运行时、音频质量或性能证据。^[PR #6886]\n\n## QOMNI-1f — Qwen3-Omni MoE 默认值必须走显式 backend 合同\n\n- 触发：修改 Qwen3-Omni Thinker/Talker 的 MoE backend、`qwen3_omni_moe.yaml`、stage-engine argument finalization，或迁移旧的环境变量 workaround。\n- 强制：仅当 `model_arch` 为 `Qwen3OmniMoeForConditionalGeneration` 且已解析的 `moe_backend` 为缺失或 `auto` 时，finalization 才默认写入 `triton`；任何显式 backend 必须原样保留。随仓库发布的 `qwen3_omni_moe.yaml` 必须在 Thinker stage 0 和 Talker stage 1 都显式 pin `moe_backend: triton`；Code2Wav 不继承该模型专属 MoE 设置。\n- 禁止：通过 `VLLM_USE_FLASHINFER_MOE_FP16` 或其他 process-wide 环境变量选择 backend；把默认值写成覆盖用户/deploy 显式选择；只改 deploy YAML 却不覆盖 legacy 与 typed builder 的最终 engine args。\n- 验收：以 Qwen3-Omni default 和一个显式 backend control，分别经 `build_legacy_engine_args_dict` 与 `build_engine_args_dict_from_omni_stage_config` 断言最终 `moe_backend`；默认两路径均为 `triton`，显式值不变。helper 单测只能补充分支覆盖，不能代替 builder-level assertion。PR 只提供 compile/Ruff/diff 检查及因缺少 `torch` 未运行的 targeted pytest，故不构成 GPU 稳定性、性能或音频质量证据。^[PR #7019]\n\n## QOMNI-1g — 共享 code predictor 的 RoPE theta 必须先读 rope_parameters\n\n- 触发：修改 `qwen3_code_predictor._RotaryEmbedding`、Qwen3-Omni Talker code predictor config 反序列化，或 Transformers 对 `rope_theta`/`rope_parameters` 的布局。\n- 强制：构造 `inv_freq` 时优先 `config.rope_parameters[\"rope_theta\"]`（若 mapping 存在），否则回退 top-level `rope_theta`，再默认 `10000.0`。Qwen3-Omni（Transformers 5.10+ 常把 checkpoint 的 `1_000_000` 只放在 nested 字段）与仍带 top-level 的 Qwen3-TTS/legacy 必须共用该顺序。\n- 禁止：只读 top-level 导致静默回退 `10000`；把 nested 优先写成破坏 TTS top-level 兼容的唯一来源。\n- 验收：参数化覆盖 nested-only、nested 优先于冲突 top-level、默认 `10000`，以及 TTS/legacy top-level（含删除 `rope_parameters`）重建正确 `inv_freq`。^[PR #7228]\n\n## QOMNI-1h — Qwen3-Omni 的 moe_backend 覆盖只认显式字段，字面 auto 不算隐式\n\n- 触发：修改 `_maybe_set_qwen3_omni_moe_backend`、`OmniStageModelConfig` 的 `_TrackExplicitConfigFields`/`_omni_explicit_fields`，量化/NVFP4 deploy，或 stage engine-args 投影时机。\n- 强制：仅当 `moe_backend` 不在显式字段集合（typed 读 `_omni_explicit_fields`；dict 路径 key 缺失）时才默认写入 `triton`；deploy/CLI 显式写出的 `moe_backend: auto` 必须原样保留，交给 vLLM 量化 backend 选择。覆盖应在 stage projection 时带上 explicitness，不得仅靠 finalize 再猜字面值。\n- 禁止：用 `get(\"moe_backend\", \"auto\") == \"auto\"` 把显式 `auto` 当成未设置；在 finalize 二次覆盖时丢弃 `_omni_explicit_fields`；只测 helper 不测 legacy+typed builder。\n- 验收：显式 `auto`、显式非 auto、未设置三路径分别经 legacy 与 typed builder；NVFP4 CI stage 0 最终为 `auto`，未量化默认 stage 仍为 `triton`。^[PR #7200]\n\n## QOMNI-1h2 — Thinker PP 必须把层捕获装进 IntermediateTensors 并让 runner 透传\n\n- 触发：修改 Qwen3-Omni Thinker PP、`capture_layer_indices`/`PP_CAPTURE_PREFIX`、`make_empty_intermediate_tensors`，或 `GPUModelRunner.extract_multimodal_outputs` / `make_omni_output` 对非最终 PP rank 返回值的处理。\n- 强制：staged run 且存在 `accept_hidden_layer` 时，捕获层索引为 `[0, accept_layer]`。非最终 PP rank 在返回的 `IntermediateTensors` 中除 `hidden_states`/`residual` 外，必须附带 `capture_{idx}`；接收 rank 对 `idx < start_layer` 的捕获从 intermediate 读取并 `.clone()`，不得复用下一步会被覆盖的 receive buffer。\n- 强制：Thinker wrapper 在存在跨 rank 入站捕获时，用 `make_empty_intermediate_tensors_factory([\"hidden_states\", \"residual\", *incoming_captures], hidden_size)` 覆盖空张量工厂。runner 必须把 `IntermediateTensors` 当作合法 model output：不得强行 `make_omni_output`；`extract_multimodal_outputs` 透传；profiling/graph dummy 若需要 sampler 行，只取 `hidden_states` 张量字段。\n- 禁止：非最终 rank 只回传 hidden/residual 而丢掉 Talker 所需捕获；假定 stock vLLM 在非 staged 路径也要 return tuple；或因类型检查失败把 PP 路径改成同步-only workaround 却不修 handoff。\n- 验收：PP≥2 覆盖入站捕获 clone、非最终 rank 的 capture key 集合，以及 runner 对 `IntermediateTensors` 的 extract/dummy/make_omni_output 分支；同步与异步 PP 均不得以 `Invalid hidden states type` 启动失败。^[PR #7345]\n\n## QOMNI-1h3 — 混合长度 streaming batch 的 crop 必须用整窗 trim，不得把 padding 当有效未来帧\n\n- 触发：修改 `Qwen3OmniMoeCode2Wav.chunked_decode_streaming` 的 start/end 切片、`seq_token_counts`、left context，或混长 batch 的 decoder trim 计算。\n- 强制：decoder 对整批共享同一 right-edge trim。`tail` 必须由 `codes.shape[-1]*total_upsample - batch_wav.shape[-1]` 相对整窗测量，再对每行用 `start = max(0, left_context*up - tail)` 与 `end = max(0, code_seq_len*up - tail)`。padding 不提供有效未来 codec 上下文。\n- 禁止：按单行 `code_seq_len` 相对整窗波形长度算 per-row tail（短请求会 clamp 到 0 并保留 padding 样本）；只用时长/长度相等证明 crop 正确。\n- 验收：独立单请求 oracle 对比混长 batch 的值与长度；覆盖 eager/cudagraph、多种短帧/left-context、batch 顺序，以及 singleton→mixed→singleton 连续流无 skip/repeat。^[PR #7340]\n\n## QOMNI-1h4 — Thinker 中间态捕获必须补上延迟相加的 residual\n\n- 触发：修改 Qwen3-Omni Thinker 的 `capture_layer_indices` / `return_hidden_states`，或把 decoder 层输出交给 Talker。\n- 强制：vLLM 把 block 更新和 residual 分开，直到下一次 RMSNorm 才相加。有 residual 时捕获 `hidden_states + residual`；residual 为 `None` 时只 clone `hidden_states`。写入前 view 成 `(-1, hidden)`。捕获不得改变最终 Thinker 输出。\n- 禁止：只复制 update 张量；把无 residual 的 embedding clone 和有 residual 的层当成同一公式；用捕获开关改变主 forward 数值。\n- 验收：单 PP rank 上用会拆开 hidden/residual 的层断言捕获值等于逻辑状态（无 residual 为输入，下一层为 hidden+residual），且开启捕获后的最终输出与不捕获一致。^[PR #7304]\n" + }, + "head": { + "repos/vllm-omni/models/qwen-omni/rules.md": "---\ntitle: \"Qwen-Omni

Qwen3-Omni 的 `SupportsQuant`、`WeightsMapper`、compressed-tensors/AWQ\n ignore/exclude 名称，或 Thinker、Talker、Code2Wav 的嵌套模型构造。\n- 强制：在统一 Qwen3-Omni wrapper 暴露 checkpoint 到最终嵌套模块路径的映射，并先对完整\n quantization config 执行一次映射；`ComponentQuantizationConfig` 必须递归映射每个非空\n component 和 default config。子 stage 检测到该映射后不得再次改写名称，但仍须合并自己的\n `packed_modules_mapping`，供量化 scheme 匹配 fused module。该嵌套 metadata 是 optional：outer-map-once\n marker 已存在时，缺少 attribute 必须 no-op；存在且非空时才 merge，且不得清掉 outer marker。\n- 禁止：只映射一个 component wrapper 而给它标记为已映射；让 Thinker/Talker/Code2Wav 各自\n 重复应用 stage mapper；因修复名称匹配而把 BF16 router/encoder 也纳入量化；或把该构造期\n 映射修复描述成 quantization kernel / inference hot path 变化。\n- 验收：以真实 component-wrapped `CompressedTensorsConfig`（含 `None` component 与 default）\n 断言 `ignore` HF names 映射到最终路径；加载 AWQ checkpoint 时三 stage 都能完成 weight\n loading，且不出现缺模块/参数或 routed-expert quantized-weight 属性错误。CPU regression 还必须覆盖\n missing quant config、outer-mapped Talker-style model 缺 `packed_modules_mapping` 的

`pipeline: qwen3_omni_moe_thinker_only`；该 registry key 必须直接绑定静态单 stage\n text→text `PipelineConfig`，不能重新进入由 HF config 决定全三 stage 的\n `qwen3_omni_moe` resolver。没有显式 YAML 的 Captioner/Thinking checkpoint 继续由 resolver\n 自动选择 thinker-only 拓扑。\n- 禁止：把 Instruct 的 `enable_audio_output` 当作 thinker-only 的充分条件；只修改 YAML 而未\n 注册静态 key；或以 key 存在/原始 YAML 替代最终 resolved pipeline 的断言。\n- 验收：分别以 Instruct 和 Thinking/Captioner HF config 经 `StageConfigFactory` 加载该 YAML，\n 断言同一 `qwen3_omni_moe_thinker_only` pipeline、仅一个 Thinker stage 和 text output；同时\n 直接解析该 key，断言其对象身份为 registry 的静态 `PipelineConfig` 而非

linear、`encoder_attention_heads`，或其 global tensor-parallel 初始化。\n- 强制：以 `encoder_attention_heads % global_tp_size` 判定该 audio-encoder layer 是否可分片。可整除时保持 global TP；不可整除时仅该 encoder layer 的 attention QKV、attention output projection、FC1 和 FC2 都以 `disable_tp=True` 构造，且 local attention head count 按 effective TP=1 计算。\n- 禁止：仅关闭 QKV 或仅修正 `num_local_heads` 而让 output/FFN 仍分片；把这项 fallback 扩大为整个 Qwen3-Omni 模型关闭 TP；或把 PR 的 TP1/2/4/8 手工音频请求、MI350x full-workload throughput 数字归因于该 fallback。\n- 验收：分别覆盖 heads 可被和不可被 global TP 整除的构造，断言四个 linear 的 `disable_tp` 一致、attention local-head count 正确，且 encoder 外的 Thinker/Talker TP 配置未被此条件改写。PR 仅报告手工请求与整体 workload 测量，未给出该局部回退的独立性能或质量证明。^[PR #4322]\n\n## QOMNI-1e — Qwen2.5-Omni code2wav 缺失时必须 soft-fail，不能复活跨 stage 的旧 speech helper\n\n- 触发：修改 Qwen2.5-Omni 的 `generate_audio`、`_codec_to_audio`、`_init_token2wav_model`、weight loading、Talker sampling/logits，或 Thinker/Talker/Code2Wav 的 staged 构造。\n- 强制：`_codec_to_audio` 在 `token2wav` 缺失时必须直接返回 `None`；`_init_token2wav_model` 只能由持有已解析 `hf_model_folder` 的 Token2Wav weight-loading 路径调用；语音生成维持 Thinker → Talker → Code2Wav 的 stage handoff。\n- 禁止：无参数调用 `_init_token2wav_model()`；恢复 `generate_speech` 或 `_convert_to_codec_tokens`；仅 thread `sampling_metadata` 就声称修复旧 helper（其 Talker `compute_logits` 调用仍带已失效的额外参数）；或让单一 wrapper 违反 staged ownership 而同时拥有 Talker 和 Token2Wav。\n- 验收：目标树中不存在两个已删除 helper 或无参数 initializer call；`token2wav is None` 的 `_codec_to_audio` 路径返回 `None` 而非 `TypeError`；Token2Wav load path 仍向 initializer 传入解析后的 HF directory。PR 未新增测试或 E2E，故这些是静态/call-site 合同，不构成运行时、音频质量或性能证据。^[PR

`model_arch` 为 `Qwen3OmniMoeForConditionalGeneration` 且已解析的 `moe_backend` 为缺失或 `auto` 时，finalization 才默认写入 `triton`；任何显式 backend 必须原样保留。随仓库发布的 `qwen3_omni_moe.yaml` 必须在 Thinker stage 0 和 Talker stage

engine args。\n- 验收：以 Qwen3-Omni default 和一个显式 backend control，分别经 `build_legacy_engine_args_dict` 与 `build_engine_args_dict_from_omni_stage_config` 断言最终 `moe_backend`；默认两路径均为 `triton`，显式值不变。helper 单测只能补充分支覆盖，不能代替 builder-level assertion。PR 只提供 compile/Ruff/diff 检查及因缺少 `torch` 未运行的 targeted pytest，故不构成 GPU 稳定性、性能或音频质量证据。^[PR #7019]\n\n## QOMNI-1g — 共享 code predictor 的 RoPE theta 必须先读

`config.rope_parameters[\"rope_theta\"]`（若 mapping 存在），否则回退 top-level `rope_theta`，再默认 `10000.0`。Qwen3-Omni（Transformers 5.10+ 常把 checkpoint 的 `1_000_000` 只放在 nested 字段）与仍带 top-level 的 Qwen3-TTS/legacy 必须共用该顺序。\n- 禁止：只读 top-level 导致静默回退 `10000`；把 nested 优先写成破坏 TTS top-level 兼容的唯一来源。\n- 验收：参数化覆盖 nested-only、nested 优先于冲突 top-level、默认 `10000`，以及 TTS/legacy top-level（含删除 `rope_parameters`）重建正确 `inv_freq`。^[PR #7228]\n\n## QOMNI-1h — Qwen3-Omni 的 moe_backend 覆盖只认显式字段，字面 auto 不算隐式\n\n- 触发：修改 `_maybe_set_qwen3_omni_moe_backend`、`OmniStageModelConfig` 的 `_TrackExplicitConfigFields`/`_omni_explicit_fields`，量化/NVFP4 deploy，或 stage engine-args 投影时机。\n- 强制：仅当 `moe_backend` 不在显式字段集合（typed 读 `_omni_explicit_fields`；dict 路径 key 缺失）时才默认写入 `triton`；deploy/CLI 显式写出的 `moe_backend: auto` 必须原样保留，交给 vLLM 量化 backend 选择。覆盖应在 stage projection 时带上 explicitness，不得仅靠 finalize 再猜字面值。\n- 禁止：用 `get(\"moe_backend\", \"auto\") == \"auto\"` 把显式 `auto` 当成未设置；在 finalize 二次覆盖时丢弃 `_omni_explicit_fields`；只测 helper 不测 legacy+typed builder。\n- 验收：显式 `auto`、显式非 auto、未设置三路径分别经 legacy 与 typed builder；NVFP4 CI stage 0 最终为 `auto`，未量化默认 stage 仍为 `triton`。^[PR #7200]\n\n## QOMNI-1h2 — Thinker PP 必须把层捕获装进 IntermediateTensors 并让 runner 透传\n\n- 触发：修改 Qwen3-Omni Thinker PP、`capture_layer_indices`/`PP_CAPTURE_PREFIX`、`make_empty_intermediate_tensors`，或 `GPUModelRunner.extract_multimodal_outputs` / `make_omni_output` 对非最终 PP rank 返回值的处理。\n- 强制：staged run 且存在 `accept_hidden_layer` 时，捕获层索引为 `[0, accept_layer]`。非最终 PP rank 在返回的 `IntermediateTensors` 中除 `hidden_states`/`residual` 外，必须附带 `capture_{idx}`；接收 rank 对 `idx < start_layer` 的捕获从 intermediate 读取并 `.clone()`，不得复用下一步会被覆盖的 receive buffer。\n- 强制：Thinker wrapper 在存在跨 rank 入站捕获时，用 `make_empty_intermediate_tensors_factory([\"hidden_states\", \"residual\", *incoming_captures], hidden_size)` 覆盖空张量工厂。runner 必须把 `IntermediateTensors` 当作合法 model output：不得强行 `make_omni_output`；`extract_multimodal_outputs` 透传；profiling/graph dummy 若需要 sampler 行，只取 `hidden_states` 张量字段。\n- 禁止：非最终 rank 只回传 hidden/residual 而丢掉 Talker 所需捕获；假定 stock vLLM 在非 staged 路径也要 return tuple；或因类型检查失败把 PP 路径改成同步-only workaround 却不修 handoff。\n- 验收：PP≥2 覆盖入站捕获 clone、非最终 rank 的 capture key 集合，以及 runner 对 `IntermediateTensors` 的 extract/dummy/make_omni_output 分支；同步与异步 PP 均不得以 `Invalid hidden states type` 启动失败。^[PR #7345]\n\n## QOMNI-1h3 — 混合长度 streaming batch 的 crop 必须用整窗 trim，不得把 padding 当有效未来帧\n\n- 触发：修改 `Qwen3OmniMoeCode2Wav.chunked_decode_streaming` 的 start/end 切片、`seq_token_counts`、left context，或混长 batch 的 decoder trim 计算。\n- 强制：decoder 对整批共享同一 right-edge trim。`tail` 必须由 `codes.shape[-1]*total_upsample - batch_wav.shape[-1]` 相对整窗测量，再对每行用 `start = max(0, left_context*up - tail)` 与 `end = max(0, code_seq_len*up - tail)`。padding 不提供有效未来 codec 上下文。\n- 禁止：按单行 `code_seq_len` 相对整窗波形长度算 per-row tail（短请求会 clamp 到 0 并保留 padding 样本）；只用时长/长度相等证明 crop 正确。\n- 验收：独立单请求 oracle 对比混长 batch 的值与长度；覆盖 eager/cudagraph、多种短帧/left-context、batch 顺序，以及 singleton→mixed→singleton 连续流无 skip/repeat。^[PR #7340]\n\n## QOMNI-1h4 — Thinker 中间态捕获必须补上延迟相加的 residual\n\n- 触发：修改 Qwen3-Omni Thinker 的 `capture_layer_indices` / `return_hidden_states`，或把 decoder 层输出交给 Talker。\n- 强制：vLLM 把 block 更新和 residual 分开，直到下一次 RMSNorm 才相加。有 residual 时捕获 `hidden_states + residual`；residual 为 `None` 时只 clone `hidden_states`。写入前 view 成 `(-1, hidden)`。捕获不得改变最终 Thinker 输出。\n- 禁止：只复制 update 张量；把无 residual 的 embedding clone 和有 residual 的层当成同一公式；用捕获开关改变主 forward 数值。\n- 验收：单 PP rank 上用会拆开
