        previews the T-shirt at the Student cell, the lowest of the Member and Student prices the student
        holds
      - places the order at the Student price with both audiences frozen on the line
      - >-
        previews the T-shirt at the Member cell of the Regular period, the audiences and the period in the
        explanation
      - 'places the order with the audience provenance frozen on the line, and stamps the period’s first sale'
      - >-
        places at the same Member price the preview showed, the audience bound to a fixture binding id that is
        not a uuid
      - >-
        15. keeps the placed line as it was when the rule changes afterwards, while the next preview moves; a
        second sale leaves the stamp

        refuses the placement 409 placement_refused with audience_lapsed and the decision’s sentence, never
        repricing silently
      - 'leaves the checkout open with the refusal on its trail, and placed no order'
      - '14. leaves the order placed before the lapse as it was: no retroactive repricing'

# Member pricing through preview and placement

## Verification Boundary

The suite drives the composed local API dispatcher and its registered routes.

## What This Suite Proves

The registered cases check member pricing through preview and placement 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

PostgreSQL and the exercised Commerce persistence or workflow code are real. Remote service records, clocks and transports follow the suite’s fixtures.

## Must Not Be Doubled

The database constraints, role restrictions, locks and transactions exercised by this suite must use PostgreSQL.
