Error Model

Failures in bijux-proteomics-knowledge should help a reviewer tell whether the problem is local, upstream, downstream, or a boundary mismatch. Error handling that hides ownership makes the package harder to trust.

Error Rules

• surface contradictions, incomplete evidence, and invalid review state explicitly
• keep trust-model failures distinct from storage or transport failures
• do not smooth over unresolved evidence conflict for the sake of downstream convenience

First Proof Check

• package error types and failure paths
• tests that assert the intended failure class
• neighboring packages when a failure crosses a handoff seam
