        prices the T-shirt at standard beside the membership whose own line says
        qualifies_same_order: false (the contract’s policy, read from the item payload until 0.3.0
        publishes)

        refuses the placement price_changed with the member and the standard price, never honouring
        a grant that disappeared (05 §4)

        opens the membership’s gate and keeps the T-shirt’s closed prerequisite_not_met while the

        delivers the membership, meets the T-shirt’s prerequisite with order.prerequisite_met on the
        history, and opens its gate
      - delivers the T-shirt in turn
      - >-
        blocks the T-shirt prerequisite_failed when the membership fails for good, with the block on
        the history and the exception raised for staff (05 §4)

# Same cart grants

## Verification Boundary

This suite calls the composed local HTTP handler over the prepared database. It checks same cart grants through request contracts and the enforcing security boundary.

## What This Suite Proves

The bound scenarios identify the assertions this suite contributes. Source anchors retain the exact test cases; where a capability scenario has several contributing suites, a single binding does not imply that every branch runs here.

## What It Does Not Prove

Local handler execution does not establish deployed routing, queue delivery or browser behavior. It also supplies no latest result until a qualification run records one.

## Real Dependencies and Test Doubles

The database and imported Commerce persistence services are real. Fixtures create the records owned by this run. Signed local security contexts and the composed handler exercise the request boundary. Financial facts are supplied by a local fixture provider. Queue publication uses the suite’s recording or scripted publisher.

## Must Not Be Doubled

Keep the composed handler, permission enforcement, request validation and database writes real when claiming this local API coverage. Scripted financial, queue or carrier outcomes must remain visibly separate from deployed integration evidence.
