Ordinary fictional irrigation-story board. In this imagined garden only, a recorder code says BLUE = more water than this plan needs now; GREEN = enough for this plan now; RED = less than this plan needs now. At 09:00 bed L is BLUE and bed M is RED. Tomorrow is empty. The agreed fictional plan says pause adding water at BLUE and review/add the planned amount at RED with the supervising adult. This is not a calibrated local sensor or a rule for real plant care. F4 independently describes CSIRO's Chameleon research as helping farmers interpret soil water at different depths to make decisions; its page was last updated in 2022, not a 2026 result tally.
