Create internal/ai/correlation package:
1. Correlation Detector (detector.go):
- Tracks events across resources
- Detects when events on one resource follow events on another
- Calculates average delay between correlated events
- Confidence scoring based on occurrence count
- Persists to ai_correlations.json
2. Features:
- GetCorrelations() - All detected relationships
- GetCorrelationsForResource() - Relationships for one resource
- GetDependencies() - What resources depend on this one
- GetDependsOn() - What this resource depends on
- PredictCascade() - Predict what will be affected
- FormatForContext() - AI-consumable summary
3. Integration:
- Wire to alert history in router startup
- Map alert types to correlation event types
- Add correlation context to enriched AI context
Example AI context now includes:
'When local-zfs experiences high usage, database often follows within 5 minutes'
This enables the AI to understand infrastructure dependencies
and predict cascade failures.
All tests passing.
