| Label | Definition | Score impact |
|---|---|---|
| ✅ Match | Essential meaning, legal intent, register, and factual content fully preserved. Minor paraphrasing that does not alter meaning is acceptable. | 100% per unit |
| ⚠ Partial Match | Main idea conveyed but with omitted qualifiers, awkward phrasing, minor lexical substitutions, or grammar errors that do NOT reverse or distort meaning. | 70–95% per unit |
| ❌ Addition | Content not in source is added; OR a factual detail is reversed (e.g. illegal → legal), substituted (invented address), or action direction is altered (unloading → loading). | −1% per occurrence |
| ❌ Omission | A full scoring unit is entirely absent from the rendition — not rendered in any form. | −1% per occurrence |
