Crop Scout is a measurement HUD and grow assistant on Quest 3. It scans a real microgreens tray, measures health and coverage, and saves the result with a record of how it got that number, so a grower can track change day to day without stopping to take notes with wet hands. The problem it solves is guessing: growers usually judge a tray by eye, with no measurement, no history, and no record to compare against. Crop Scout measures the tray in the headset, in real light, hands-only, and keeps the history.
Before this build: v2 HUD + SAM core.
Built Oct 27 to Nov 4: validation, trace, gate, and costs. Validation checks SAM's measurements against my own by-eye estimates. Trace saves which tools ran, the measurement, the time, and a code for that photo. Gate asks first before harvest or delete changes anything. Costs caps SAM measurements at 25 a day, visible in Settings, and falls back to just the AI guess at the cap.
