- alibaba-video: fragment/surface 对齐当前 Distribution API，改用 createExactModelPrimaryGenerationFragment + sealGenerationRequestDraft，修复 @hypit/elaborator 不导出 createAssembledGenerationFragment 导致 CLI 加载失败 - alibaba-video: 端口表移除单端口 atMostOneOf（该约束至少需 2 个端口） - provider-wanx: parameters.duration 改为整数（DashScope 要求），新增 firstNumber 读取 number 端口值 - alibaba-wanx: 新增 demo.svrun 作为 Run Source（build 需吃 .svrun，.svml 是 Author Source） - 默认模型 wan3.0-video；本地实测 Build complete 并已导出视频

Summary
Adds Alibaba Cloud DashScope video generation support to Hypit, wired end-to-end and verified locally (a real video was generated and exported).
What is included
packages/alibaba-video- the Model + SVML Surface (@hypit/alibaba-video, capabilityalibaba-qwen-vvg) with<alibaba:TextVideo>and<alibaba:ReferenceVideo>surfaces. Ports: prompt, duration, resolution, aspectRatio, referenceImage.createExactModelPrimaryGenerationFragment+sealGenerationRequestDraft), matching@hypit/seedance.packages/provider-wanx- the missing Endpoint/Provider that actually calls DashScope (wan3.0-video): async submit to video-synthesis with X-DashScope-Async, poll the task, then collect output.video_url.alibaba-wanx/- a minimal working example: demo.svml (Author Source) + demo.svrun (Run Source) + hypit.runtime.json.Verification
Local end-to-end:
hypit build alibaba-wanx/demo.svrun --runtime alibaba-wanx/hypit.runtime.json --followreached Build complete (~2m20s), and the resulting video was exported successfully.Notes
wan3.0-video(configurable in hypit.runtime.json).parameters.durationto be an integer; sending a string fails validation. Calling this out because it cost real debugging time.atMostOneOf, which the Distribution rejects (it needs at least two ports); removed.createAssembledGenerationFragmentfrom@hypit/elaborator, which the current Distribution does not export; rewritten.Happy to adjust naming, packaging or the default model to match upstream conventions.
