Overview

Shared helpers for the server-side Claim Update response verification tests. Inferno (acting as the client) sends a sequence of update submissions to the server under test; these helpers reload each submission by its unique tag and compare the submitted Claim's items against the ClaimResponse the server returned. No live state is used - everything is reloaded from the tagged, persisted requests/responses.

#item_bearing_update_steps ⇒ Object

The item-bearing steps (cancel-entire-request carries no items, so item.sequence checks do not apply to it).

end

#submitted_claim(request) ⇒ Object

The Claim under submission is the first Bundle entry (a conformant update Bundle also includes the referenced prior Claim per spec-65, so select by position, not by type-order).
