Could pop-up stock, samples, and returned units require manual reconciliation?
A small inventory reconciliation sheet with anomaly flags and a documented adjustment log.
What we could measure together
Measure: Unexplained unit difference after an event (units per event).
Reconcile starting units, sales, samples, damage, and returns for existing event records without imputing missing counts.
Acceptance boundary: Owner approves inventory adjustments; no sales or waste reduction is assumed.
