Inventory moved buckets, not totals

Shopify says certain active holds from draft orders and transfer shipments are moving from reserved to committed. The available, on-hand and total inventory values remain unchanged in this migration.

That distinction matters in competitor research and operations reporting. A bucket label can move while the underlying inventory totals stay fixed. If a dashboard only shows the bucket delta, it is easy to escalate a reporting migration as though stock changed.

A bounded review rule

1. Timestamp the change — record when the bucket movement appeared.
2. Add platform context — note the Shopify change before interpreting the metric.
3. Check the totals — compare available, on-hand and total before calling it a real stock event.

This is a measurement and systems-design rule, not a claim that every reserved inventory movement is covered. The Shopify changelog is the source for the specific migration.
