Security and Safety

Security guidance should protect the package boundary as well as the code path itself.

Operating Rules

• security fixes should preserve explicit validation and contract boundaries
• unsafe coercion or implicit defaults are operational and security risks here
• do not hide sensitive execution assumptions inside generic core helpers

First Proof Check

• src/bijux_proteomics/domain/program_spec.py and domain/targets.py
• src/bijux_proteomics/domain/lifecycle.py and domain/validation.py
• packages/bijux-proteomics-core/tests
