Codebase Architecture Refactoring Complete 🏗️
Published on December 13, 2025 by David Rug
The past weeks have been spent on a comprehensive refactoring of the entire InterBrain codebase. While invisible to users, this work is foundational for everything that comes next.
Before & After
The codebase has been transformed from scattered files to self-contained feature slices.
Before: Scattered Architecture

Problems:
• Commands separated from the features they serve
• Monolithic files with mixed responsibilities
• Hard to know where to find or add functionality
After: Vertical Slice Architecture
Each feature now owns its commands, services, components, state, and documentation - all in one place.
Documentation & Navigability
Every feature now has comprehensive documentation organized in a clear cascade:

Both human contributors and AI agents can now navigate from high-level overview down to implementation details. This dramatically improves development velocity - whether fixing bugs, adding features, or understanding how things work.
By the Numbers

What's Next: Private Beta
This refactoring lays the foundation to prepare the InterBrain for a private beta launch. Clean architecture and comprehensive documentation mean faster iteration on user feedback.
The last steps before launching:
1. Onboarding Tutorial - A guided introduction for new users
2. Feedback Pipeline - Making it effortless for testers to report issues
3. Known Issues - Fixing remaining bugs that affect core functionality
The private beta will be a small group of testers helping identify rough edges before broader release. Stay tuned for the announcement!
