Initial CHORUS project setup
🎭 CHORUS - Container-First P2P Task Coordination System - Docker-first architecture designed from ground up - Environment variable-based configuration (no config files) - Structured logging to stdout/stderr for container runtimes - License validation required for operation - Clean separation from BZZZ legacy systemd approach Core features implemented: - Container-optimized logging system - Environment-based configuration management - License validation with KACHING integration - Basic HTTP API and health endpoints - Docker build and deployment configuration Ready for P2P protocol development and AI integration. 🤖 Generated with Claude Code
