+# Unified Road Defect Dataset - FRDC Pseudo-labeled v1+ (Co-DETR, gap-completed)
+
+An improved version of the v1 distillation set. v1 used **Co-DETR** pseudo-labels at
+conf >= 0.5, which **dropped 4,316 test images entirely** (no confident detection) and
+missed lower-confidence boxes. v1+ **keeps every v1 Co-DETR box unchanged** and only
+**adds the boxes v1 was missing** (non-overlapping detections recovered from Co-DETR on
+the dropped images + RTMDet), so v1's strong labels are preserved while coverage is
+completed.
+
+Unlike v2 (which fused both teachers with Weighted Boxes Fusion and **averaged/moved**
+Co-DETR's boxes), v1+ is **add-only** — no existing Co-DETR box is modified.
+
+**Contents**
+- GT train (RDD-2022 + UAV-PDD2023 + RoadDamageVision, 4-class, original labels).
+- Pseudo-labeled test: **5,081 images, 9,160 boxes** = v1's 8,023 Co-DETR boxes (kept)
+  + 1,137 added missing boxes (362 images v1 had nothing for).
+- val: the original held-out GT val (unchanged), identical to base/v1/v2 for fair A/B.
