Link to Mill A OER decline
Confidence87%Overripe share at Mill A rose from 6.1% to 10.6% in 7 days (ramp-camera grading) — the largest contributor (32%) to the OER drop from 22.3% to 21.6%. Harvest-to-mill time also increased (17 h → 26 h). Recommend tighter ramp thresholds for Estates B & E and same-day evacuation from CPs.

Prototype model metrics — demonstration only. Known limitations: occlusion in dense loads, low light after 18:00, rotten vs overripe confusion. Grader confirmation required for rejects.
