Example run: a planted checkout bug on a demo store

What the run did

• Target: /demo/shop/ on Sybqa’s own server, run locally on 127.0.0.1 for this recording. Trailhead Supply is not a real shop: nothing is sold, sent or charged.
• Browser: WebKit 27.2, at Desktop 1280 × 800 and Narrow 320 × 740.
• Plan: the deterministic planner, from the goal “Buy a product and check out”. AI review and AI routing were off, and the plan did not allow writes.
• Recorded: 2026-11-05 01:07:03 UTC, 271 checks and 8 run notes in total.

Journey: Buy a product and check out

1. click [data-testid="product-link-trail-mug"]
2. expectVisible [data-testid="product-title"]
3. click [data-testid="add-to-cart"]
4. expectText [data-testid="cart-count"] with “1”
5. click [data-testid="view-cart"]
6. expectVisible [data-testid="cart-line"]
7. click [data-testid="checkout-link"]
8. fill #checkout-name with “Demo Shopper”
9. fill #checkout-email with “shopper@example.com”
10. fill #checkout-card with “4242 4242 4242 4242”
11. click [data-testid="place-order"]
12. expectVisible [data-testid="order-confirmation"]

Journey: Checkout validation

1. click [data-testid="place-order"]
2. expectVisible [data-testid="checkout-errors"]

The typed name, email and card number are the demo store’s own published test values.

Journey results

The runtime check recorded the browser error from the planted bug: undefined is not an object (evaluating 'lines.reduce').

What happens next

2 checks failed, all in the checkout journey. In a real report each failure comes with recorded steps and a fix brief to paste into the tool that edits the site. After the fix, the same check is run again: see the retest on the fixed store.

What this run did not cover

• Not run (10 checks): Some page timing metrics are unavailable in this browser.
• Not run (2 checks): slow-network: network throttling needs Chromium; this run uses webkit.
• Not run (2 checks): double-submit: double-clicking "Add to cart" sent no submission request; nothing to deduplicate.
• Not run (2 checks): Required flow stage not observed: Order confirmation; full flow coverage remains incomplete.
• Run notes, not counted as Not run checks:
  • Additional AI verification was not enabled for this check.
  • LLM exploration disabled by profile.
• No payment, order or email exists: the demo store has no back end, so these checks cover what the browser showed, not stored data.
• One fictional store, one browser engine and two screen sizes. It says nothing about any other site and is not a measure of how often Sybqa finds bugs.
• This recording used WebKit at 1280 and 320 px. Runs started from the console use Chromium at 1440, 390 and 320 px, so browser-specific checks such as slow-network throttling and page timing metrics can differ.

Every recorded check and run note

All 271 checks and 8 run notes from this run, each with the state and summary it recorded, word for word.
