CHORUS Licensing Master Development Plan

Date: 2025-09-01
Version: 1.0
Status: Ready for implementation
Priority: CRITICAL - Foundation for all CHORUS revenue protection

Executive Summary

This master plan coordinates the implementation of comprehensive licensing across the entire CHORUS ecosystem. Currently, BZZZ has zero license enforcement, WHOOSH has no license integration, and KACHING lacks production license server capabilities. This represents a critical revenue protection gap that must be resolved immediately.

Business Impact

Current Revenue Risk

• $0 recurring revenue - No license enforcement means unlimited free usage
• License sharing - Single licenses used across multiple clusters without restriction
• Feature leakage - Enterprise features available to all users regardless of tier
• No upselling mechanism - Users unaware of license limitations or upgrade benefits

Target Business Model

• Subscription-based licensing with tiered features and node limits
• Real-time license enforcement with immediate suspension capabilities
• Automated upselling through usage-driven upgrade suggestions
• Comprehensive audit trails for compliance and revenue tracking

Project Coordination Overview

Repository Status

• KACHING: feature/license-authority-server ✅
• BZZZ: feature/licensing-enforcement ✅
• WHOOSH: feature/license-gating-integration ✅

All projects are on dedicated licensing branches and ready for coordinated development.

Cross-Project Integration Points

KACHING → BZZZ

• License Validation API: BZZZ calls KACHING for activation/heartbeat
• Token Management: KACHING issues short-lived tokens to BZZZ
• Cluster Binding: KACHING tracks BZZZ cluster assignments
• Suspension Enforcement: KACHING can immediately disable BZZZ clusters

KACHING → WHOOSH

• License Status API: WHOOSH fetches current license details
• Usage Quotas: KACHING provides quota limits and current usage
• Upgrade Suggestions: KACHING generates tier-based recommendations
• Feature Definitions: KACHING defines what features each tier includes

BZZZ → KACHING

• Usage Telemetry: BZZZ reports job completion metrics to KACHING
• Heartbeat Data: Regular cluster health and activity reports
• License Validation: Real-time license status verification
• Audit Events: Security and compliance event reporting

Testing Strategy

Unit Testing (Each Project)

• KACHING: License CRUD operations, token generation/validation
• BZZZ: Configuration loading, heartbeat logic, feature gates
• WHOOSH: License display components, feature gate hooks

Integration Testing (Cross-Project)

• End-to-End License Flow: Create license → BZZZ activation → WHOOSH display
• License Suspension: Admin suspends → BZZZ stops → WHOOSH shows status
• Quota Enforcement: Usage approaches limits → alerts → upgrade prompts
• Cluster Migration: Deactivate old cluster → activate new cluster seamlessly

Load Testing

• License Server Performance: 1000+ concurrent license validations
• Heartbeat Scaling: 100+ BZZZ clusters with 15-minute heartbeats
• Database Performance: License lookups under high query load

Security Framework

Cryptographic Protection

Conclusion

This master plan transforms CHORUS from having zero license enforcement to comprehensive revenue protection across all products. The coordinated implementation ensures consistent licensing behavior, prevents revenue leakage, and establishes the foundation for sustainable recurring revenue growth.

The plan prioritizes immediate revenue protection (BZZZ enforcement) while building toward automated revenue optimization (WHOOSH upselling) - delivering both short-term security and long-term growth capabilities.

Next Step: Begin Phase 1A (KACHING Admin Tooling) to establish the foundation for the entire licensing ecosystem.
