Bin-to-pallet traceability for a post-harvest operator

The operator ran a six-week season at a volume that made manual recording impossible, and a traceability obligation that made not recording unacceptable. The existing process captured grower and date but lost the link to block and pick once fruit merged on the line — which meant that in a recall, the recall would have been everything.

The build was constrained by the line itself. Scanning had to add no time at all, in a cold, wet environment, with gloves. We used fixed scan points and inferred the rest from timing and line position rather than asking anyone to do anything extra, and validated the model against a season of historic data before it ran live.

It went in mid-season, which was not the plan but was the only window available. The rollback path was tested more carefully than the feature, and it was not needed.
