feat: Add FedRAMP R5 Balance initiatives and 20x Phase One implementation with REST API

[yflop]

Overview

This PR implements the complete FedRAMP R5 Balance initiatives and FedRAMP 20x Phase One pilot support, along with a production-ready REST API server and monitoring infrastructure.

What's New

🚀 R5 Balance Implementations

• R5.SCN - Significant Change Notifications (RFC-0007 compliant)
• R5.CRS - Continuous Reporting Standard with 6 key metrics
• R5.MAS - Minimum Assessment Standard framework
• R5.SSAD - Storing and Sharing Authorization Data

🎯 FedRAMP 20x Phase One

• All 11 Key Security Indicators (KSIs) per release 25.05C
• 51 sub-requirements with validation logic
• Continuous reporting proposal generation
• Machine-readable JSON outputs

🔧 Infrastructure & API

• Complete REST API server with all endpoints
• Database layer with PostgreSQL support
• Continuous monitoring framework
• Alert management system (webhook, email, Slack, PagerDuty)
• Web dashboard for real-time monitoring
• Docker and Kubernetes deployment support

📚 Documentation

• Comprehensive implementation status documentation
• Production deployment guide
• API reference documentation
• CLI command reference
• Architecture diagrams and examples

Technical Details

New Dependencies

• github.com/gorilla/mux - HTTP routing
• github.com/rs/cors - CORS support
• Additional cloud provider SDKs for future integrations

API Endpoints

All new endpoints follow RESTful conventions:

POST /api/v1/ksi/validate # Validate KSIs
GET /api/v1/ksi/report/{csoId} # Get KSI report
POST /api/v1/scn # Create SCN
GET /api/v1/crs/metrics/{csoId} # Get CRS metrics
POST /api/v1/mas/assessment # Create assessment
POST /api/v1/ssad/package # Create SSAD package

CLI Commands

New commands added to gocomply_fedramp:

gocomply_fedramp scn create      # Create significant change notification
gocomply_fedramp ksi validate    # Validate Key Security Indicators
gocomply_fedramp mas create      # Create assessment
gocomply_fedramp ssad package    # Manage authorization packages
gocomply_fedramp frmr fetch      # Fetch machine-readable documents

Testing

• All core functionality tested locally
• API endpoints validated with curl and Postman
• Continuous monitoring alerts verified
• Docker deployment tested

Breaking Changes

None - all changes are additive. Existing functionality remains unchanged.

Production Ready

This implementation includes:

• Production Dockerfile with security hardening
• Kubernetes deployment manifests
• Monitoring and alerting setup
• Deployment scripts
• Comprehensive documentation

Future Work

While this PR provides complete R5 Balance and 20x implementations, some traditional FedRAMP documents (SAR, POA&M, SAP) have basic structures only and are marked as work-in-progress for future enhancement.

Would you please take a look at the failed CI?

Looks like it is because the GitHub Actions workflow is configured to use Go 1.14.15.
I have updated the build.yml and am working on release.yml to use Go 1.19 which should resolve the issue.

Pushing changes in a moment.

***Changes have been pushed. Should be ready to try again.

[yflop]

@isimluk This should resolve the workflow issue (mismatched Go version now updated).

[isimluk]

Thanks. Makefile will have to be amended as well to use go install instead of go get

[yflop]

Thanks. Makefile will have to be amended as well to use go install instead of go get

Excellent. I have done what you have suggested using go install instead of 'go get'.

[yflop]

@isimluk , I noticed the workflow failed so I simulated the workflow locally and made some changes.
It should pass - although I thought that on the last run.
Thanks for patience on the PR.

[yflop]

@isimluk I have cloned separately and successfully run the workflow.

Please, attempt again when you have time.
Thanks,

Success!

@isimluk, Bumping this one.
Thanks so much.
