Origin custody is credible. Destination custody is not yet explainable.
The bag was identified, screened, sorted, and loaded at Miami through four independently supported events. After BDO 2174 arrived in Atlanta, the expected arrival scan did not enter the trusted ledger. Six minutes later, an unregistered device asserted a duplicate custody event in Transfer Zone T4.
Memory assessment: the bag may be physically present at ATL, but its current holder and seal condition require verification before release.
