STL file repair report

Turn a broken STL file into a clear repair report.

For makers and small print shops, the report matters as much as the file: it explains what changed, what remains risky, and what was skipped.

Repair reports include issue categories, counts, severity, and a print-ready score derived from the checker output.

Before/after summaries make it clear whether a safe repair improved the file or only produced a diagnostic result.

Saved reports and repaired STL downloads are planned as private artifacts with owner checks and deletion status.

PDF export can follow JSON reports after the core checker and paid download boundary are verified.
