⏸️ Componentes Não Testados (Dependências Externas)

5. Vision Extraction (Phase 1C)

Status: ⏸️ CÓDIGO COMPLETO, TESTES PENDENTES

Razão: ml-offload-api não está rodando (localhost:9000 offline)

Módulos Implementados:

• ✓ vision_client.py - Integration com ml-offload-api (OpenAI-compatible)
• ✓ models.py - BoundingBox, VisionDetection, FusedElement
• ✓ dom_analyzer.py - lxml + BeautifulSoup + Playwright position extraction
• ✓ fusion_engine.py - IoU algorithm para vision-DOM matching
• ✓ extractor.py - End-to-end multimodal extraction orchestration

Testes Planejados:

• Vision model inference (CLIP, LLaVA)
• DOM element extraction + XPath generation
• IoU matching accuracy (>0.7 para fusion)
• End-to-end pipeline (vision → DOM → fusion)

Pending: Start ml-offload-api + test suite
