Vitte

Vitte Roadmap 161-200 (Professional Edition)

Program frame

Scope: complete Vitte's transition from advanced compiler to full language platform without compromising reliability.

Guiding principle: any added complexity must stay lower than the reliability confidence it creates.

Global definition of done:

  • measurable functional impact
  • actionable diagnostics quality
  • non-regression and robustness tests
  • synchronized technical documentation
  • explicit residual-risk statement

Mandatory completion checklist for 200:

  • stable compile
  • credible self-host path
  • real backend
  • professional diagnostics
  • complete tooling baseline
  • maintainable stdlib/runtime
  • minimal ecosystem package
  • IDE support
  • deterministic builds
  • active replay/debug/fuzz/stress workflows
  • strong technical documentation
  • verified minimum security baseline
  • extensible architecture
  • defined technical governance

Final rule: Added complexity must remain lower than gained system reliability confidence.
