How to use this tool

- Review row diagnostics for invalid or duplicate outcomes.
- Copy output mode (URLs/tags/both) and export CSV audit reports.
Domain normalization

- Lowercasing host/path can reduce duplicate canonical variants.
- Default port stripping avoids redundant canonical forms.
Quality controls
- Row-level errors preserve invalid input for manual correction.
- Dedupe report highlights canonical collisions before deployment.
- Use CSV audits for content ops review workflows.
