export for labs
Every submission becomes a training row — observation, action, reward, ground truth — exported as JSONL for reinforcement learning and supervised fine-tuning.
Real mold, plates, plant growth — blur-checked, tagged, deduplicated.
Handwritten or printed pages — must be sharp with visible text/lines.
Read a science sentence — speech must match transcript before payout.

Vision rows with labels — reward on verified upload.
Lab notes
OCR pairs — image observation, text ground truth.
Voice read
Speech rows — audio action, verified transcript reward.
Models trained on Petri contributor data jump on held-out science benchmarks — genes, stats pipelines, lab photos, and more.

Labs need verifiable reward signals, not random uploads. $PETRI pays contributors when their row lands in the export — ready for RL and fine-tuning pipelines.
