 Human expert annotations of definitional defects in Ukrainian legislation.
 Gold-standard labels for the **LegDefQA** benchmark.
 
-## Annotation Schema
+## Annotation Task
 
-### Circulus in definiendo
-| Label | Description |
-|-------|-------------|
-| TRUE_DEFECT | Definition is normatively empty, adds no distinguishing criterion |
-| DOMAIN_REUSE | Root word repeats but definition is substantively meaningful |
-| FALSE_POSITIVE | Pipeline error, no actual overlap |
-| SKIPPED | Annotator skipped this item |
+Given a legal definition extracted from Ukrainian legislation, the annotator classifies it along two independent dimensions.
 
-### Ignotum per ignotum
-| Label | Description |
-|-------|-------------|
-| CRITICAL | Term undefined anywhere in the corpus |
-| CROSS_REF | Term defined in another law, needs explicit reference |
-| COMMON | Well-known term, no definition needed |
-| FALSE_POSITIVE | Pipeline error, term defined in the same law |
-| SKIPPED | Annotator skipped this item |
+### Dimension 1: Circulus in definiendo
 
-## Source
+> **Question:** Does the definition add at least one distinguishing criterion that is not already present in the term itself?
 
-300 definitions stratified from 5,799 extracted by the DefectRadar pipeline from 44,021 active Ukrainian legislative acts.
+| Label | Description | Example |
+|-------|-------------|---------|
+| `TRUE_DEFECT` | Definition is normatively empty -- it restates the term without adding content | "програмно-апаратна помилка" defined as "помилка у програмному забезпеченні" |
+| `DOMAIN_REUSE` | Root word repeats but the genus provides substantive narrowing | "Державний реєстр лікарських засобів" defined as "єдина державна інформаційна система, що містить відомості про зареєстровані лікарські засоби" |
+| `FALSE_POSITIVE` | Pipeline error -- no actual morphological or semantic overlap | Rare; indicates extraction or lemmatization error |
 
-Strata: 100 circulus-flagged, 100 ignotum-flagged, 100 pipeline-clean.
+### Dimension 2: Ignotum per ignotum
+
+> **Question:** Can a jurist apply this norm without consulting other laws for the meaning of terms used in the definition?
+
+| Label | Description | Example |
+|-------|-------------|---------|
+| `CRITICAL` | Term undefined anywhere in the legislative corpus; norm is inapplicable without subjective interpretation | "креативне вираження" -- not defined in any Ukrainian law |
+| `CROSS_REF` | Term is defined in another law; an explicit cross-reference would resolve the gap | Financial terms in payment services law defined only in Banking Law |
+| `COMMON` | Well-known term; no statutory definition needed | General terms like "особа", "майно" |
+| `FALSE_POSITIVE` | Pipeline error -- term is actually defined in the same law | Extraction missed the definition |
+
+## Sampling Strategy
+
+300 definitions sampled from 5,799 extracted by DefectRadar from 44,021 active Ukrainian legislative acts:
+
+| Stratum | Count | Description |
+|---------|-------|-------------|
+| `circulus` | 50 | Pipeline flagged circulus only |
+| `ignotum` | 100 | Pipeline flagged ignotum only |
+| `both` | 50 | Pipeline flagged both defects |
+| `clean` | 100 | Pipeline found no defects |
