Mill certificates: new Product Reference matching

We’ve shipped an upgrade to mill certificate ↔ inventory matching by adding Product Reference as an alternate key alongside heat codes. This matters for people who receive certificates for individual plates etc. that could be from the same heat code as many other items.

What’s new

• Inventory and mill-certificate heats now support Product Reference.

• Matching logic is heat-first: Heat-code matches always take precedence when it is completed for an inventory item. Product Reference is used when no heat match is available. This means no unexpected changes for existing data.
• Tag rules can include product-reference matches (without double-counting when both keys match the same heat).

• Product Reference is now incorporated into imports and exports of inventory, used for matching certificates, and is included where present in certificate packs.
