Artifact Contracts

Artifacts matter because they survive the moment of execution and become someone else's input or evidence.

Package Surface

• serialized contract payloads
• program, target, and readiness records
• execution-contract artifacts consumed by runtime or downstream packages

First Proof Check

• src/bijux_proteomics/domain/program_spec.py, domain/repositories.py, and domain/targets.py
• src/bijux_proteomics/interfaces/cli/app.py and interfaces/cli/__main__.py
• packages/bijux-proteomics-core/tests
