+# DentBench-VL (extended)
+
+Persona-conditioned dental Vision-Language dataset for intraoral photographs.
+2,105 records across 15 canonical dental classes, six structured fields per
+record (diagnosis, severity, findings, recommendation, explanation, rationale).

+## Files
+
+- `complete_annotations_clean_extended.json` — final merged corpus (2,105 records)
+- `manual_annotations.jsonl` — 650 external records with full
+  Writer-Editor-Diagnoser provenance (annotation, blind diagnoser audit,
+  resolution decision)
+
+## Annotation pipeline
+
+External images annotated through a Writer-Editor-Diagnoser pipeline:
+Writer drafts the six-field annotation conditioned on the source label,
+Editor enforces per-style length budgets, blind Diagnoser independently
+re-diagnoses from the image alone. Disagreements resolved through a
+confidence-based rule (308 of 326 disagreements resulted in a Diagnoser
+override, replacing source-dataset labels).
