Deployment Boundaries

Deployment boundaries matter because a package can be publishable without being the right place to run a service.

Operating Rules

• core is primarily a published contract layer, not an independently deployed runtime service
• deployment boundaries matter here as version and dependency boundaries
• operator-facing deployment concerns should stay in runtime or application layers

First Proof Check

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