Product availability claims: why stock changes must stay separate from a VIP10 result
Stock status is a merchant inventory event. It should never be rewritten as evidence that a discount code succeeded or failed.
Recorded result
$6.00 CAD observed discount on a $60.00 CAD cartVIP10 was observed at the guest-cart stage. No identity, shipping address, payment information, checkout submission, or order was used. Payment-method-specific totals and location-specific taxes were not assessed.VIP10 is reusable and has no minimum order requirement. No fixed expiry date is currently published for VIP10. Availability and checkout conditions remain subject to the merchant’s current terms.
Availability is time-sensitive
A public product listing can change between two checks. Products may sell out, be removed, return later, or show different purchase controls across sessions. A valid verification workflow checks the live listing immediately before it tries to add an item to the cart.
The archive should record a stock skip when no suitable item is available. This tells readers why no cart-code event occurred without manufacturing a negative code result.
Do not generalize from one listing
One available product does not prove that the full catalog is in stock, just as one unavailable product does not prove that every listing is unavailable. The public statement must match the inventory context actually observed.
This rule prevents a common quality problem on coupon pages: stock language that looks current but is really copied from an earlier session or a different listing.
How the future checker should behave
A compliant checker should query the public catalog, filter to listings that show normal purchase availability, rotate through a controlled candidate set, and log a separate inventory-unavailable state when none can be tested.
It should never claim a fresh verification event on a day when it did not complete a permitted cart check. That restraint is what makes the log useful.
Available means a selectable candidate at that moment
For the purpose of an evidence run, availability has a narrow operational meaning: the public storefront visibly offers an ordinary product or variation that can be added to a guest cart. It does not establish a long-term inventory level, guarantee fulfillment, or tell readers which product they should choose. The agent selects an available candidate only so the cart can be tested without treating a sold-out item as a code failure.
The archive should also preserve the difference between a product page that exists and a product that can actually enter the cart. A visible page may be out of stock, missing a usable variation, or blocked by an ordinary storefront condition. Recording those inventory skips separately prevents the site from manufacturing either a positive code result or a negative code result when the test itself could not be performed.
