Dependency Direction

Dependency direction in bijux-proteomics-lab should make ownership more obvious as the package grows, not less. Imports that save a little time but hide who owns meaning are structural debt.

Direction Rules

• consume recommendation and evidence inputs without re-owning scoring or knowledge semantics
• keep shared meaning in foundation and durable program contracts in core instead of copying them locally
• treat repositories as lab state boundaries, not as generic execution infrastructure

First Proof Check

• imports in packages/bijux-proteomics-lab/src/bijux_proteomics_lab
• package tests that exercise the seam
• neighboring handbooks when dependency pressure crosses a boundary
