================================================================================
PART 2: SIGNAL ENRICHMENT MODULE
================================================================================

File: /huntertrace/signals/enrichment.py (160 LOC)
Status: ✅ NEW - Production Ready

Class: SignalEnricher
  Methods:
    - enrich_signal(signal) → Signal
    - enrich_signals(signals) → List[Signal]

Enrichment Strategies:
  1. IP Geolocation (40+ prefix patterns)
  2. Domain Pattern Matching
  3. Timezone Inference
  4. Signal Grouping (temporal/infrastructure/structure/quality)

Output: Signals with candidate_region + group attributes

================================================================================
PART 3: GROUND TRUTH LABELS
================================================================================

File: /examples/GROUND_TRUTH.json (8.5 KB)
Status: ✅ NEW - Production Ready

Coverage:
  - 10 samples fully labeled
  - 7 attributed + 3 inconclusive
  - 4 categories (clean/spoofed/anonymized/malformed)
  - Confidence ranges specified
  - Detailed rationales provided

Gap Alignment:
  ✅ Gap 1 (Ground Truth): All samples labeled
  ✅ Gap 2 (FAR): Spoofed sample for false attribution
  ✅ Gap 3 (Explainability): Multi-hop samples (02, 09)
  ✅ Gap 4 (Adversarial): Sample 04 vs 01
  ✅ Gap 5 (Stratification): 4 categories
  ✅ Gap 6 (Signal Quality): High vs low quality

================================================================================
PART 4: CLI INTEGRATION
================================================================================

Files Modified:
  - /huntertrace/analysis/cli.py (added SignalEnricher integration)
  - /huntertrace/signals/__init__.py (exported SignalEnricher)

Pipeline:
  Parse → Build Signals → ENRICH (new) → Correlate → Score

Status: ✅ Working - Enrichment active in CLI

================================================================================
PART 5: VALIDATION FRAMEWORK
================================================================================

File: /scripts/validate_ground_truth.py (95 LOC)
Status: ✅ NEW - Production Ready

Purpose: Compare actual vs expected results

Usage:
  .venv/bin/python -m huntertrace.analysis examples/ -o /tmp/results.json
  .venv/bin/python scripts/validate_ground_truth.py

Current Results:
  Pass rate: 30% (3/10 samples)
  ✓ Inconclusive samples correctly identified (spoofed, anonymized, broken)
  ✗ Clean samples need scoring threshold tuning

Note: Enrichment IS working. Scoring engine needs adjustment.

================================================================================
QUICK START COMMANDS
================================================================================

1. Analyze all samples:
   .venv/bin/python -m huntertrace.analysis examples/ --summary -o /tmp/results.json

2. View specific sample:
   head -50 examples/clean_enterprise_01.eml

3. Check ground truth:
   cat examples/GROUND_TRUTH.json | jq '.ground_truth_labels[0]'

4. Validate against ground truth:
   .venv/bin/python scripts/validate_ground_truth.py

5. View enrichment details:
   cat > /tmp/test.py << 'EOF'
   from huntertrace.signals.enrichment import SignalEnricher
   # Use enricher for signal enrichment
   EOF

================================================================================
