# Repo Hygiene Rules

## Do Commit
- source code;
- documentation;
- small fixtures;
- config examples;
- migration files;
- test data under size limits.

## Do Not Commit
- `.env` with secrets;
- large rasters;
- model weights;
- generated cache;
- local database volumes;
- node_modules;
- Python virtualenvs;
- personal paths.

## Naming
- backend modules use snake_case;
- frontend components use PascalCase;
- docs use uppercase topic names or numbered folders;
- fixtures describe region and purpose.

## Generated Outputs
Generated exports should go under `exports/` and be gitignored unless they are tiny documented sample fixtures.
