    "notes": "Thirteen new original photographs were inspected by AI; nine have one approximate selected target, and four remain cropped or uncertain qualitative checks. Four older AI absence references were tested only at native resolution and are summarized separately. The entire image was downsampled until the selected target was approximately 32 or 16 pixels wide, then upsampled back to its original size with LANCZOS. No crop or paste creates the synthetic views; tiled inference uses four overlapping tiles plus whole-image context. These tests measure no actual distance or flight range. At synthetic 32 px, tiled scanning matched eight of nine selected targets versus seven for whole-frame scanning, but produced 49 unmatched alerts versus 11. The incomplete AI references cannot establish that these extra alerts are false positives. Model weights were unchanged; this selected photo test is not a field accuracy estimate."
