    test_cases:
      - allows a plan the ordering profile lists when its tender requirement is deposit
      - refuses a pay-now ordering profile (ordering_profile_not_deposit) whatever plans it lists
      - 'refuses a plan the profile does not list, naming what is offered, and a profile offering none'
      - >-
        sends every line at its total in minor units, the subject an order, the ordering profile as the
        contract’s order_type, the start date and the card as the method kind
      - carries the order id and number when given (the create of item 2 adds them to the same body)
      - >-
        answers a quoted summary: the amount up front, the financed rest, each line’s split by reference,
        every installment
      - splits nothing of a line the answer leaves out
      - answers a refused or unavailable summary with no amounts and the reason
      - >-
        reads the frozen summary of an order with a plan, and none of an order without one or with a summary
        of another plan
      - >-
        is the frozen deposit less the succeeded deposit legs; an installment leg never counts; a declined one
        neither
      - is the order’s total less its legs for an order with no plan
      - 'keys the schedule, an outcome, a reduce, a cancel and an installment invoice link'
      - >-
        names the schedule and the installment in an attempt’s instrument reference, and reads them back;
        another kind’s reads nothing
      - >-
        reflects the schedule: what is paid, what remains (scheduled, invoiced, declined, failed), the next
        due date, each installment in sequence order
      - 'builds the reduce body of the contract’s item 5 from the executed lines, under the cancellation’s key'
      - >-
        caps the memo at the units’ share of the line’s up-front part less what was credited before, the last
        units taking the rest, so the shares sum to the part

# InstallmentChoiceAdmission (D-P3-29)

## Verification Boundary

The unit suite checks the named contract or helper with controlled inputs.

## What This Suite Proves

The registered cases check installmentChoiceAdmission (D-P3-29) with their fixture records and assertions. Scenario bindings name only the examples those cases exercise.

## What It Does Not Prove

A registered file supplies no run result or verified conformance by itself. Local fixtures do not establish deployed cross-service behavior or complete browser journeys.

## Real Dependencies and Test Doubles

Inputs and external responses are controlled in process; this suite establishes no deployed service behavior.

## Must Not Be Doubled

The named contract validation or component behavior under assertion must use its actual implementation.
