Engineering

A model validator refuses to construct a cycle whose B'' is present without ∞0'. The Completion Rule made impossible to violate by construction, regardless of what code path produced the cycle. The first surface where the language becomes executable rather than legible.

reST is usually treated as the documentation layer beneath 'real' software. The codex inverts that. The Constitutional Block becomes a directive that fails the build on paraphrase. The validation protocol becomes doctests. One canonical source, every later surface linking in.

A workflow library can be run end-to-end by an agent. A 5QLN surface, faithfully built, refuses to certify a cycle whose human side was empty. The series builds these surfaces in code: reST, Python, MCP, TypeScript. Each carries the asymmetry. None of them automate it away.
