TRANSPARENCY NOTE — This is a shortened demonstration made from an invented storefront with intentional defects. It is not client work, a testimonial, or evidence of commercial results.

PUBLIC STOREFRONT EVIDENCE AUDIT / DEMONSTRATION / 390 · 768 · 1440PX

Repair the purchase path before polishing it.

Illustrative store: Northline Workshop (fictional) · Inspection surface: home, collection, product, cart, FAQ · Current desktop Chrome

Executive read

The demonstration store communicates a credible product, but mobile purchase controls obscure validation, a collection filter loses state, and the cart gives weak failure feedback. The first repair pass should protect product selection and cart recovery.

ILLUSTRATIVE FINDINGS

1 high · 2 medium
Each tied to a page, viewport, reproduction path, and evidence reference.

High · 01

Validation disappears behind the sticky purchase bar.

ADD TO CART

Location: /products/field-lamp · 390px
Reproduction: Leave the required finish unselected, then activate Add to cart.
Observed: The validation message is inserted beneath a fixed purchase bar and cannot be read without scrolling past the control.
Recommendation: Move validation into the visible buy-box flow and reserve its vertical space. Keep focus on the invalid option group.
Confidence: High · reproduced twice in the inspected browser.

Medium · 02

Returning from a product clears the collection filter.

Location: /collections/lighting · 768px and 1440px

Reproduction: Apply “In stock,” open a product, then use the browser Back control.

Evidence: Capture 06 shows 8 results before navigation; capture 07 shows all 24 products after return.

Recommendation: Encode the filter in the URL or restore it from navigation state. Verify Back/Forward behavior before changing the filter UI.

Confidence: High.

Medium · 03

A failed cart update looks successful.

Location: /cart · all inspected widths

Observed: A deliberately failed public cart request leaves the quantity control at its optimistic value. The total does not change and no visible message explains why.

Evidence: Network record 03; console record 02; captures 09–10.

Recommendation: Roll the control back to the confirmed quantity and announce an inline retry message near the changed item.

Confidence: Medium; failure handling observed without completing checkout.

Recommended repair order

Expose product validation and verify keyboard focus at 390px.
Make cart update failure visible and recoverable.
Preserve collection filters across product navigation.

This order reflects purchase-path risk and reproducibility—not invented revenue impact.
