Sample Report Output:

🔬 COMPREHENSIVE BUILD FAILURE ANALYSIS COMPLETE
📊 Executive Summary
Build #1380 in the DEMO_PIPELINE (29) pipeline has failed with critical PowerShell environment issues that are blocking deployment. This is a persistent, recurring problem with 80% confidence in the root cause identification.

🎯 KEY FINDINGS
🚨 PRIMARY ROOT CAUSE
PowerShell Core (pwsh) Missing from Build Environment
• Error: Unable to locate executable file: 'pwsh'
• Impact: Blocking all PowerShell-based test execution
• Confidence: 80%

🚀 ACTIONABLE RECOMMENDATIONS
🔥 IMMEDIATE ACTIONS (30-60 minutes)
1. Fix PowerShell Environment ⭐ TOP PRIORITY
# Add to pipeline YAML:
- task: UseDotNet@2
  inputs:
    packageType: 'runtime'
    version: '6.x'
- script: |
