## Compact Rules

### Go conventions
- Use existing error wrapping pattern: `fmt.Errorf("context: %w", err)`
- Channel-based pipeline — keep goroutine lifecycle clean (close channels in correct order)
- No comments unless non-obvious WHY; no docstrings
- Prefer named returns only when it aids clarity in short functions
- Use `strings.EqualFold` for case-insensitive column name comparison

### Project conventions
- Config structs live in `internal/app/config/`
- ETL interfaces live in `internal/app/etl/types.go`
- Transformer implementations in `internal/app/etl/transformers/`
- Azure operations via `internal/app/azure/main.go`
- Per-job transformer creation (not shared) when job has storage config
