A structural preflight does not prove full X12 or Amazon partner conformance. Current licensed implementation guides remain controlling.

Support boundary

Structural preflight, honestly scoped.

This 855 pack checks the X12 envelope, control numbers, transaction identity, segment counts, high-value anchor segments, and the cross-document reconciliation still required.

It does not claim full X12 or Amazon partner conformance. Production use remains controlled by the current licensed X12 and Vendor Central implementation guides.

X12 envelope

Deterministic controls

ISA/IEA, GS/GE and ST/SE controls and counts are checked against the exact received bytes.

Named rule pack

Visible structural scope

Required anchors and the business checks still outstanding are reported separately.

Partner profile

No invented conformance

Licensed transaction-set and current account-guide rules remain explicit production requirements.
