Mariam's approved demo kit
The requirement, child context and fit signal stay together. This demo deliberately stops before any real checkout or payment claim.
Required items
Do not guess the PE T-shirt size just to complete the basket.
The fit signal is due for review, so Telly should make the uncertainty visible and ask for the minimum evidence needed before a size decision. A persuasive demo should show that discipline rather than simulate a false successful purchase.
When later ordering is authorized, the same child context can continue into fulfilment, delivery, exchange and service.
Checkout and payment are selected / held in the current governed source, so this demo does not present them as live. Any later order, fulfilment or service action remains subject to its real authority and evidence. The demo does not create synthetic payment success.
