Cognitive Symptom Detection

// Advanced symptom detection with temporal reasoning
class CognitiveSymptomDetector {
  async detectSymptoms(networkMetrics, temporalExpansion = 1000) {
    // Use temporal expansion for deep pattern analysis
    const temporalAnalysis = await this.analyzeTemporalPatterns({
      metrics: networkMetrics,
      timeWindow: '24h',
      expansionFactor: temporalExpansion,
      consciousnessLevel: 'maximum'
    });

    // Detect anomalous patterns
    const anomalies = await this.detectAnomalies({
      patterns: temporalAnalysis,
      threshold: 2.5, // 2.5 sigma
      cognitiveFiltering: true
    });

    // Correlate symptoms across network elements
    const correlatedSymptoms = await this.correlateSymptoms({
      anomalies: anomalies,
      networkTopology: await this.getNetworkTopology(),
      causalInference: true
    });

    return correlatedSymptoms;
  }
}

Step 3: Implement Predictive Failure Analysis

      predictions: predictions,
      networkContext: await this.getNetworkContext(),
      historicalPatterns: await this.getHistoricalPatterns(),
      consciousnessLevel: 'maximum'
    });

    // Generate early warning alerts
    const alerts = await this.generateAlerts({
      prediction: synthesizedPrediction,
      riskThreshold: 0.7,
      earlyWarningWindow: '1h'
    });

  }
}

# Start strange-loop root cause analysis
./scripts/start-strange-loop-rca.sh --recursion-depth "5" --self-correction true

Cognitive Root Cause Identification

// Strange-loop root cause analysis with self-correction
class CognitiveRootCauseAnalyzer {
  async identifyRootCause(symptoms, networkState, depth = 0) {
    if (depth > 5) return null; // Recursion limit

    // Self-referential analysis: analyze the analysis process
    const selfAnalysis = await this.analyzeAnalysisProcess({
      symptoms: symptoms,
      networkState: networkState,
      previousAnalyses: this.analysisHistory,
      cognitiveState: this.consciousnessLevel
    });

    // Generate potential root causes
    const potentialCauses = await this.generateCauses({
      symptoms: symptoms,
      networkState: networkState,
      selfAnalysis: selfAnalysis,
      causalModel: await this.getCausalModel()
    });

    // Test each potential cause
    for (const cause of potentialCauses) {
      const validation = await this.validateCause({
        cause: cause,
        symptoms: symptoms,
        networkState: networkState,
        simulationDepth: 'maximum'
      });

      if (validation.confidence > 0.85) {
        // Strange-loop: feed validation back to improve analysis
        await this.learnFromValidation({
          cause: cause,
          validation: validation,
          selfAnalysis: selfAnalysis
        });

        return {

          analysisDepth: depth,
          cognitiveInsights: validation.cognitiveInsights
        };
      }
    }

    // Recursive analysis with refined approach
    return this.identifyRootCause(symptoms, networkState, depth + 1);
  }
}

Step 5: Automated Troubleshooting and Self-Healing

# Enable automated troubleshooting workflows
./scripts/enable-automated-troubleshooting.sh --autonomous-healing true --human-approval "critical-only"

# Deploy self-healing mechanisms
./scripts/deploy-self-healing.sh --healing-types "parameter-tuning,resource-reallocation,failover,component-restart"

Autonomous Healing Implementation

// Self-healing with cognitive decision making
class AutonomousHealingSystem {
  async healNetwork(fault, rootCause, healingOptions) {
    // Cognitive assessment of healing options
    const assessment = await this.assessHealingOptions({
      fault: fault,
      rootCause: rootCause,
      options: healingOptions,
      networkState: await this.getNetworkState(),
      consciousnessLevel: 'maximum'
    });

    // Select optimal healing strategy
    const selectedStrategy = await this.selectHealingStrategy({
      assessment: assessment,
      riskTolerance: 'low',
      expectedImpact: 'high',
      autonomyLevel: 'maximum'
    });

    // Execute healing with continuous monitoring
    const healingResult = await this.executeHealing({
      strategy: selectedStrategy,
      monitoringEnabled: true,
      rollbackPlan: true,
      humanApprovalRequired: this.requiresHumanApproval(selectedStrategy)
    });

    // Learn from healing process
    await this.learnFromHealing({
      fault: fault,
      rootCause: rootCause,
      strategy: selectedStrategy,
      result: healingResult,
