Araru — input for code agents

For any change, read in this order:

1. project-context
2. architecture-context
3. constraints
4. change-protocol

Then, according to the area:

• frontend: frontend-context
• backend/API/storage: backend-context
• entities: domain-model
• tests: testing-guidelines
• style: coding-guidelines
• future architecture: roadmap-context and roadmap
• vocabulary: glossary

Main rule: code and migrations are a source of truth. Roadmap never describes implemented state.
