Two gates, two owners. We prove it at the FAT. The customer accepts it at the SAT.
Test scripts exercise every routing decision, every handshake, every exception path, on purpose, before it ships.
Sustained rate against the design target, under real load. The WMS handshake confirmed at real volume. Then sign-off.
To the customer's real maintenance capability.
Stated cleanly, before a failure, not after.
Who reaches it. Assigned here; the network is L21.
By criticality (L26), docs, every serviceable part reachable.
