Open-source control planes for reliable AI systems: govern language, align agent behavior, and verify software changes.
Deterministic authority, controlled scope expansion, managed execution, and auditable evidence for AI coding agents.
   Canonical project vocabulary and merge-time drift detection for coding agents. |    Domain language control for search, RAG, runtime text, and agent workflows. |
Govern meaning → align agent language → control code changes
Each project is independently usable, but together they form a coherent reliability stack.
