Extensibility Model

Extensibility only helps when it preserves the core package argument. In bijux-canon-reason, extension points should widen claim formation, checks, and reasoning artifacts intentionally rather than invite neighboring concerns in through convenience hooks.

What To Check

• name the extension points that are safe because they preserve the package role
• name the boundaries that extensions must not cross
• prefer extension seams that keep review pressure visible in code and tests

First Proof Check

• src/bijux_canon_reason and reasoning artifacts for the structural ownership boundary
• tests for claim, verification, and provenance evidence for executable confirmation that the structure still holds

Bottom Line

If bijux-canon-reason needs hidden structure to defend claim formation, checks, and reasoning artifacts, the architecture is already too opaque.
