One batch, found everywhere
A recall is a where-used query with a clock on it. Batch B-7741 proves the chain: sixty units received, sixty consumed, 58 shipped to three customers, two on the shelf, every hop reconciling before anyone picks up a phone.
◆ The trace, both directionssixty units, accounted.
| Batch B-7741, traced | Documents | Units |
|---|---|---|
| Received into raw store | 1 | 60 |
| Issued to production orders | 2 | 60 |
| Shipped in customer deliveries | 3 | 58 |
| Still on hand, finished store | 2 |
Sixty in, sixty consumed across two orders, 58 shipped across three deliveries, two on the shelf: the units reconcile at every hop, which is exactly what the query must prove before anyone calls a customer. Sample values are illustrative, never client data.
◆ Where the trace snapsrepacks and plant walls.
The delivered where-used trace follows a batch number, so it ends wherever the number changes: repacking, relabeling, a new batch at a second plant. Practitioners report recall drills stalling at exactly these seams. The landed genealogy maps old number to new at every transformation, and the walls come down.
◆ The drill is the metrichours, measured on a quiet day.
Regulators and customers measure recall readiness in elapsed hours. Running the query quarterly against a random batch, and recording the hours, turns traceability from a claimed capability into a number on a page.
