### Summary Related to issue #5041 First PR in a stacked series landing the HuggingFace operator end-to-end. This PR adds **only** the backend REST resource — no operator code yet. The resource is independently useful (the frontend can already integrate with it) and lets reviewers absorb the API surface before the operator class lands. ### What's changes were proposed in this PR? Introduces `HuggingFaceModelResource`, a Jersey resource registered at `/api/huggingface/*`: | Endpoint | Purpose | |---|---| | `GET /api/huggingface/models` | Browse / search models per task. Uses an in-process cache for browse mode and forwards to HF Hub for search. | | `GET /api/huggingface/tasks` | Fetch HF pipeline tags filtered to tasks with hosted inference. Cached process-lifetime. | | `POST /api/huggingface/upload-audio` | Upload audio bytes for HF audio tasks; stores in `/tmp/texera-hf-audio/` and returns the file path. | | `GET /api/huggingface/audio-preview` | Stream uploaded audio (path-validated to prevent traversal). | | `GET /api/huggingface/media-proxy` | Proxy remote media URLs (HF inference responses) to bypass browser CORS. | Also a one-line registration in `TexeraWebApplication.scala`. ### Stacked PR plan This is **PR 1 of ~9**. Subsequent PRs will add: - PR 2: refactored `HuggingFaceInferenceOpDesc` skeleton + text-generation codegen - PRs 3–5: per-task-family codegen (image, audio + media-gen, QA/ranking) - PRs 6–8: frontend (task/model selector, property-editor visibility, result-panel media) - PR 9: developer docs ### Test plan - [x] `sbt "amber/test"` passes locally - [ ] Hit `GET /api/huggingface/tasks` and confirm JSON list of supported tasks - [ ] Hit `GET /api/huggingface/models?task=text-generation` and confirm paginated model list - [ ] `POST /api/huggingface/upload-audio` with a small WAV, then fetch via `/api/huggingface/audio-preview` and confirm the bytes match - [ ] `GET /api/huggingface/media-proxy?url=…` with a known HF inference response URL and confirm the response is streamed ### Authored / co-authored using generative AI tooling?
