Document the current architecture for models and schemas:
- CORE models (models/database/) vs module models (app/modules/*/models/)
- Three schema patterns: dedicated files, inline, and no-schema
- Data flow diagram showing services access DB directly
- Gap analysis table showing model-schema alignment
- Import guidelines with canonical vs legacy re-exports
- Checklists for creating new models and schemas
