Boundary

Open-Source Boundary

This project is intentionally open at the pattern layer and intentionally closed at the detailed operating layer. The distinction is part of the launch design.

Open

The public release includes:

  • the governance model
  • the contract categories
  • the example YAML structure
  • the validator
  • synthetic examples and public receipt shapes

That is enough to understand the pattern, test it, and adapt it to a different domain.

This site’s crawler choices are explicit in /constitutional-site-manifest.json and commented in /robots.txt: search allow, user-directed retrieval allow, training mixed.

Proprietary

The release intentionally excludes:

  • detailed entity registries and mappings
  • corridor logic and domain grouping systems
  • score compression and threshold heuristics
  • internal prompt packs and narrative controls
  • private eval harnesses and anomaly rules

Those details are where a specific implementation becomes a durable operating advantage.

Why this line exists

The point of the open release is to publish the constitutional layer that makes agent-built publishing more trustworthy. The point is not to publish every private input, rule table, or research artifact that powers one company’s production system.

That line keeps the project honest:

  • open where the field benefits from shared language
  • closed where the implementation becomes a moat

What to expect if you adopt it

If you use Constitutional CMS in your own stack, your domain-specific contracts should become your own advantage. The public repo gives you a starting point. Your detailed mappings should stay yours.
