Extensibility Model

A good extension point in bijux-proteomics-intelligence makes future change cheaper without obscuring who still owns the result. A bad one turns the package into a generic hook system.

Extension Rules

• add metrics, evaluators, or loop controls only when they keep decision ownership explicit
• prefer knowledge for evidence semantics and lab for operational follow-through
• new extension points should improve reviewability of why a recommendation changed

First Proof Check

• the modules exposing extension points
• tests that prove extension behavior stays inside the package boundary
• neighboring handbooks if the extension changes a cross-package contract
