+## FCV cross-corpus validation (precision)
+
+Validated on the World Bank Fragility, Conflict & Violence (FCV) document corpus with
+the `gpt-5.6-luna` judge (Luna validation). Precision-only: there is no gold set of all
+true mentions, so recall / F1 are not reported here.
+
+### Precision by config × label
+
+| config | NAMED_DATA | DESCRIPTIVE_DATA | VAGUE_DATA | overall |
+| --- | --- | --- | --- | --- |
+| fcv_pads_east_asia | 80.1% | 81.6% | 91.8% | 81.9% |
+| jdc_operational | 86.8% | 91.3% | 91.5% | 89.1% |
+| refugee_pads | 83.8% | 92.8% | 91.9% | 89.1% |
+| reliefweb | 83.7% | 85.4% | 95.5% | 85.6% |
+
+### Specificity agreement (extractor label == judge specificity)
+
+| config | NAMED_DATA | DESCRIPTIVE_DATA | VAGUE_DATA |
+| --- | --- | --- | --- |
+| fcv_pads_east_asia | 82.8% | 88.3% | 82.1% |
+| jdc_operational | 90.2% | 83.2% | 71.7% |
+| refugee_pads | 89.4% | 86.5% | 77.5% |
+| reliefweb | 92.6% | 82.5% | 73.4% |
+
+Notes:
+- `VAGUE_DATA` is the safest label (91–95% precision); `NAMED_DATA` is the weakest (80–87%).
+- The extractor under-specifies: `VAGUE_DATA` is often judged `descriptive`, and
+  `DESCRIPTIVE_DATA` → `named` leaks occur.
+- `reliefweb` carries more bad-JSON judge errors (OCR/HTML artifacts) than the other configs.
