Architecture Success Factors

The architectural decisions that enabled MonoTerm to solve the AI CLI flickering problem.

The AI-Era Problem


The Architecture


Success Factor 1: Production-Proven Rust Crates


Success Factor 2: xterm.js as Pure Renderer


Success Factor 3: AtomicState at IPC Boundary


Success Factor 4: Pseudo-BSU/ESU (Original Contribution)


Success Factor 5: Tauri as the Bridge


Success Factor 6: Web-Based Extensibility


The Complete Picture


Conclusion

MonoTerm’s success came from recognizing the right boundaries:
  • PTY communication: Let WezTerm’s portable-pty handle it
  • VTE parsing: Let Alacritty’s parser handle it
  • Frame synchronization: Handle at IPC boundary (AtomicState)
  • Rendering: Let xterm.js WebGL handle it
  • Glue: Let Tauri bridge Rust and Web
The original contribution is Pseudo-BSU/ESU: recognizing that cursor patterns can serve as frame boundaries for AI CLI tools.
