Local Development

Local development guidance should protect package boundaries while making routine edits easier to review.

Operating Rules

• keep contract edits and downstream policy changes separate when possible
• run validation and schema proof alongside lifecycle changes
• stop when a local convenience edit starts changing durable meaning accidentally

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
