Returnable and fixed assets are identified by GIAI or GRAI. EPCIS 2.0 tracks their movement and status through object and transaction events, each validated against GS1's schema on capture.

Illustrative: one returnable crate around its cycle. The dispositions are CBV vocabulary, validated — not free text.

For the engineer who loses crates.

Shrink on returnables is a who-and-where question the counting systems cannot answer. An event history per GRAI — with an observer asserted and graded on each hop — turns "the pool is smaller this quarter" into a list of last-seen events you can act on.

Proof, not adjectives. The gateway's conformance tests pass against GS1's normative artifacts. See What for the dimension, and What ships today for the dated ledger.
