Extension: predict the next-feed time from the computed dry-back rate – Root shows ‘next feed -‘ blank while it already knows dry-back is -6.06 %/h and the P1-P

WHAT: Each Root probe card shows ‘next feed -‘ (blank), yet the steering already computes the live dry-back rate (Probe 2: -6.06 %/h) and the P1-P3 dry-back thresholds / VWC targets are set in Settings > Root. WHY: from current VWC + dry-back rate + the target trigger, the time until the next feed is a simple projection and is exactly the forward-looking number a grower wants (‘~4h to next shot’). HOW: next_feed_eta = (current_vwc – trigger_vwc) / dryback_rate; show it on the probe card, labelled ‘projected’. Works as guidance even with no pump bound (pairs with the dry-run shot-plan idea). Extends the steering. Found live 8.2.0.
