…e guide

Fully integrated v1.2 exit codes and JSON output into CI/CD workflows, demonstrating production-ready usage. Created comprehensive integration guide for all major CI/CD platforms.

Changes:

1. UPDATED .github/workflows/harmony-check.yml

   • Removed || true - now uses exit codes to fail builds
   • Added 4 demonstration jobs:
     • harmony-check: Standard check (fails on high/critical)
     • harmony-json-report: Generates JSON report with artifact upload * harmony-strict-check: Custom threshold example (0.3) * harmony-exit-codes-demo: Tests exit code behavior
   • Shows JSON parsing to display "Top 5 Functions to Refactor"
   • Demonstrates different strategies (informational, strict, etc.)

2. UPDATED .github/workflows/ci.yml

   • Added harmony check step to main CI workflow
   • Runs after pytest, before workflow completes
   • Fails build if critical disharmony detected
   • Integrated into standard test suite

3. FIXED src/divine_invitation_engine_V2.py

   • Moved vocabulary initialization message to stderr
   • Prevents breaking JSON output on stdout
   • JSON output is now clean and parseable

4. CREATED docs/CI_CD_INTEGRATION.md (~650 lines)

   • Comprehensive integration guide for all platforms
   • Exit codes reference table with recommendations
   • GitHub Actions examples (3 different approaches)
   • GitLab CI, Jenkins, CircleCI integration examples
   • JSON output parsing and dashboard integration
   • Custom threshold strategies
   • Best practices for gradual rollout
   • Full production setup example
   • Troubleshooting section

Key Demonstrations:

Exit Codes:

• 0 = Harmonious (excellent/low severity)
• 1 = Medium severity (0.5-0.8)
• 2 = High severity (0.8-1.2)
• 3 = Critical severity (≥1.2)

JSON Output:

• Valid, parseable JSON on stdout
• Includes severity counts and summary
• Can be uploaded as CI artifacts
• Enables trend tracking and dashboards

Workflows Now Show:
✅ How to fail builds on disharmony
✅ How to generate and upload JSON reports
✅ How to parse JSON and display summaries
✅ How to use custom thresholds
✅ How to test exit code behavior
✅ How to separate source/test standards
✅ How to make checks informational vs blocking

Testing:

• ✅ Exit code 3 returned for critical disharmony
• ✅ JSON output is valid and parseable
• ✅ All 20 tests still pass
• ✅ Black formatting maintained
• ✅ Stderr message doesn't break JSON

Integration Patterns Demonstrated:

• Basic: Just add harmonizer src/**/*.py to CI
• Standard: Fail on high/critical, pass on low/medium
• Strict: Use custom threshold (0.3 for excellent)
• Reporting: Generate JSON artifacts for analysis
• Gradual: Start informational, then enforce

This commit makes Python Code Harmonizer production-ready for any CI/CD platform. Teams can now enforce semantic code quality standards automatically. 💛⚓

Meta note: The tool found disharmony in its own code (main.py), showing it works! Functions like print_report and run_cli do more than their names suggest - a great example of the tool in action.
