    "SIMULATED ARMS IN THIS RUN (8 of 8): RF-DETR Small/Medium (+SAHI) (rf-detr), SAM 3.1 (exemplar + concept) (sam3), YOLO26-s/m + P2 head (1280–1536, SAHI) (yolo26-p2), GeCo2 (geco2), CountGD (countgd), T-Rex2 (interactive visual prompt) (t-rex2), Gemini Flash (tiled) (gemini-flash), OWLv2 (image-conditioned one-shot) (owlv2). Their numbers come from a simulated profile, not from live inference.",
    "SIMULATED means no inference ran on this imagery. A simulated arm draws detections from a deterministic, seeded error model whose recall/false-positive/jitter parameters are read off published benchmarks for that model (see docs/RESEARCH.md), applied to the known ground truth. It is a PRIOR describing what that model would plausibly do, not a measurement of what it did, and it must never be quoted as this model's accuracy on Central Otago imagery. Every simulated figure is replaced by a real one the moment that arm runs live.",
    "IMAGE LICENCES IN THIS RUN: CC0 (generated) (10 images).",
    "Attribution travels with the pixels: every CSV row and GeoJSON feature carries the licence and attribution of its source image, so a count lifted out of this app into a spreadsheet keeps its credit. CC BY requires that credit wherever the derived count is published; CC BY-SA additionally share-alikes anything derived from it.",
    "Georeference quality: pixel-space (demo) — approximate; real flights get EXIF/RTK georeferencing. Export coordinates are image pixels (x = column, y = row, top-left origin) in original full-resolution space. Nothing here is a map projection."
