This comprehensive refactoring addresses critical architectural issues: IMPORT CYCLE RESOLUTION: • pkg/crypto ↔ pkg/slurp/roles: Created pkg/security/access_levels.go • pkg/ucxl → pkg/dht: Created pkg/storage/interfaces.go • pkg/slurp/leader → pkg/election → pkg/slurp/storage: Moved types to pkg/election/interfaces.go MODULE PATH MIGRATION: • Changed from github.com/anthonyrawlins/bzzz to chorus.services/bzzz • Updated all import statements across 115+ files • Maintains compatibility while removing personal GitHub account dependency TYPE SYSTEM IMPROVEMENTS: • Resolved duplicate type declarations in crypto package • Added missing type definitions (RoleStatus, TimeRestrictions, KeyStatus, KeyRotationResult) • Proper interface segregation to prevent future cycles ARCHITECTURAL BENEFITS: • Build now progresses past structural issues to normal dependency resolution • Cleaner separation of concerns between packages • Eliminates circular dependencies that prevented compilation • Establishes foundation for scalable codebase growth 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
