Entrypoints and Examples

Examples should route readers into the real surface quickly and avoid making side paths look canonical.

Package Surface

• show imports and CLI usage that clarify the contract layer
• prefer examples that separate core meaning from runtime execution
• use schema examples when compatibility is the real concern

First Proof Check

• src/bijux_proteomics/program_spec.py, programs.py, and targets.py
• src/bijux_proteomics/cli.py and interfaces/cli.py
• packages/bijux-proteomics-core/tests
