Add Prefect orchestration
IP rotation infrastructure
Full uTLS integration (Phase 1B only has MVP)
HTTP/2 fingerprint randomization
Kubernetes deployment (optional - Nix sandbox preferred)

🐛 Bug Fixes - 2026-01-23 Evening Session

Critical API Contract Fixes (143/202 tests passing → 71%)

Issue: Test suite tinha múltiplas incompatibilidades de API entre implementação e testes.

Root Cause:

Assinaturas de métodos desalinhadas
Propriedades faltantes em dataclasses
Enum Strategy duplicado
Parâmetros de dataclasses sem defaults antes de parâmetros com defaults

Fixed Files

1. `src/spider_nix/extraction/models.py`

✅ BoundingBox.iou(): Adicionado método para cálculo de Intersection over Union
✅ BoundingBox.to_absolute(): Corrigido retorno de dict → tuple[int, int, int, int]
✅ VisionDetection.text: Renomeado text_content → text para compatibilidade com testes
✅ DOMElement: Reordenado parâmetros (tag_name primeiro, text_content/attributes com defaults)
✅ FusedElement: Adicionadas propriedades is_high_confidence, best_selector, best_text
✅ FusedElement: Reordenada inicialização (vision/dom opcionais com defaults)

2. `src/spider_nix/ml/strategy_selector.py`

✅ Strategy enum: Removida definição duplicada, importado de models.py
✅ update(): Adicionado parâmetro response_time_ms: float = 0.0
✅ update(): Implementado tracking de avg_response_time
✅ get_stats(): Parâmetro domain agora opcional (domain: str | None = None)
✅ record_attempt(): Adicionado método para ML feedback
✅ recommend_strategies(): Adicionado mapeamento FailureClass → Strategy recommendations
✅ get_domain_stats(): Novo método para estatísticas por domínio
✅ _best_strategy(): Corrigida lógica UCB para convergência adequada (exploration factor decay)
✅ _initialize_domain(): Adicionado campo avg_response_time: 0.0

3. `src/spider_nix/osint/web_intelligence.py`

✅ ArchiveTimeline: Reordenados parâmetros (snapshot_count/snapshots antes de opcionais)

4. `src/spider_nix/extraction/init.py`

✅ VisionExtractor: Adicionado export faltante

5. `pyproject.toml`

✅ pytest.markers: Adicionado marker slow para testes marcados com @pytest.mark.slow

Test Results

Before Fix: 58% (117/202 tests passing)

- ImportError: VisionExtractor not exported
- TypeError: BoundingBox missing iou() method
- TypeError: to_absolute() returns dict instead of tuple
- AttributeError: FusedElement missing is_high_confidence property
- TypeError: Strategy enum duplicated
- TypeError: update() missing response_time_ms parameter
- AttributeError: StrategySelector missing record_attempt() method

After Fix: 71% (143/202 tests passing)

# Core modules: 100% passing
✅ tests/extraction/test_models.py - 10/10 PASSED
✅ tests/test_strategy_selector_simple.py - 6/6 PASSED
✅ tests/test_strategy_selector.py - 11/11 PASSED

# Import validation
✅ test_imports.py - All Phase 1 imports successful

Erros restantes estão em módulos não relacionados às correções principais:

test_fusion_engine.py - API mismatch em método fuse() (parâmetro strategy)
test_failure_classifier.py - Precisa verificar assinaturas
test_web_discovery.py - Dependência pytest-httpx faltando
test_stealth_*.py - Testes de detecção (não afetados pelos fixes)

Performance Impact

Zero impacto nas features de stealth/privacidade
Zero remoção de funcionalidade
Todas as estratégias de evasão mantidas intactas:
- ✅ TLS fingerprint rotation
- ✅ Proxy rotation
- ✅ Browser mode
- ✅ Extended delays
- ✅ Headers variation
- ✅ Cookie persistence
- ✅ Epsilon-greedy multi-armed bandit
- ✅ Adaptive strategy selection

Verification Commands

# Test core extraction models
nix develop --command pytest tests/extraction/test_models.py -v

# Test strategy selector
nix develop --command pytest tests/test_strategy_selector*.py -v

# Verify all imports working
nix develop --command python test_imports.py

# Full suite (143/202 passing)
nix develop --command pytest tests/ --tb=line --no-cov -q

fix(core): resolve API contract mismatches in extraction and ML modules

- Add BoundingBox.iou() method for IoU calculation
- Fix BoundingBox.to_absolute() return type (dict → tuple)
- Rename VisionDetection.text_content → text
- Add FusedElement properties: is_high_confidence, best_selector, best_text
