Synthetic demonstration — not a client result
This example shows the structure and reasoning style of an AI App One-Flow Preflight Note. It is based on a fictional SaaS checkout journey. No real product was tested, no defect was found, and no customer, payment, repository, database, or production data was used.
1. REVIEW FRAME
Intended user: A signed-in trial user who is authorized to buy the fictional Pro plan.
Submitted journey: Sign in → choose Pro → complete a sandbox checkout → return to the app → see Pro access.
Expected final result: The same authorized account shows exactly one active Pro entitlement. A clean session sees the same state. Another account receives no access.
Illustrative materials: A 72-second sanitized recording and six screenshots showing only test accounts and sandbox payment details.
Not evaluated: Source code, webhook configuration, database records, production behavior, security, compliance, accessibility, or the rest of the application.
2. FLOW MAP
1. Trial user signs in.
2. User opens the pricing screen.
3. User selects Pro.
4. Hosted sandbox checkout completes.
5. Browser returns to a success screen.
6. Dashboard should show one active Pro entitlement.
7. A clean session should show the same final state.
The useful acceptance condition is not merely that the browser reaches step 5. It is that the authorized account reaches the stated final state once and keeps that state after the browser context changes.
3. EVIDENCE-LINKED HYPOTHESES
These are testable hypotheses, not confirmed defects.
Hypothesis 1 — The success screen may be ahead of the durable account state
Illustrative evidence link: The submitted recording ends on the success screen and does not show the dashboard from a clean session.
Why it matters: A redirect can succeed even when a later account update is delayed or missing.
What would reduce uncertainty: Show the same test account after signing out and back in, then confirm that Pro access remains visible.
Hypothesis 2 — A repeated purchase action may create an unclear intermediate state
Illustrative evidence link: The recording shows one click and one normal return. It does not show a double click, refresh, or interrupted return.
Why it matters: Users often repeat an action when a screen appears slow.
What would reduce uncertainty: Repeat the journey with a double click and a refresh while the purchase is processing, then compare the final account state.
Hypothesis 3 — Account binding has only been demonstrated for one user
Illustrative evidence link: The submitted material contains one authorized test account and no second-account boundary check.
Why it matters: A correct result for account A does not demonstrate that account B is excluded.
What would reduce uncertainty: Open the same post-purchase route as a second test account and verify that it cannot see or inherit account A's entitlement.
4. TEN MANUAL TESTS WITH EXPECTED RESULTS
Test 1 — Normal baseline
Complete the sandbox purchase once from a fresh trial account.
Expected: One success state and one active Pro entitlement for that account.
Test 2 — Close before the return screen
Complete the sandbox payment, then close the browser before the app's success page loads. Sign back in from a clean session.
Expected: The authorized account still reaches one active Pro entitlement without relying on the return page.
Test 3 — Clean-session persistence
After the normal purchase, sign out, clear the app session, and sign in again.
Expected: Pro access remains visible and the app does not ask for a second purchase.
Test 4 — Double click
Double-click the Pro purchase action in the sandbox.
Expected: The interface prevents or safely absorbs the repeat action. The final account state remains one active entitlement.
Test 5 — Refresh during processing
Refresh the app while it is waiting for the post-checkout state.
Expected: The user sees a recoverable processing or current-state message, not a permanent unpaid state or a second charge prompt.
Test 6 — Network loss after payment
In a controlled sandbox, interrupt the network after payment confirmation but before the return page finishes.
Expected: Reconnecting and signing in converges on the same single final entitlement.
Test 7 — Expired checkout
Open a sandbox checkout session, allow it to expire, and return to the app.
Expected: No Pro entitlement is granted. The app offers a clear, safe way to start a new checkout.
Test 8 — Second-account boundary
Complete the purchase as account A. Open the same plan and post-purchase routes as account B.
Expected: Account B receives no access to account A's entitlement, receipt, or private state.
Test 9 — Revisit the pricing screen
After the purchase is visible, revisit the pricing screen from the authorized account.
Expected: The screen reflects the current plan and does not present an ambiguous duplicate purchase as the primary action.
Test 10 — Repeat the complete journey from the same account
Attempt the full purchase journey again using the already upgraded account.
Expected: The app follows the product's written upgrade or renewal policy. It does not silently create a second equivalent entitlement.
5. EXAMPLE PRIORITIZATION
This prioritization is illustrative. A real note would be tied only to the submitted evidence.
NOW
• Capture the final account state from a clean session, not only the success page.
• Run the close-before-return and second-account tests before the next demo.
NEXT
• Make processing, recovery, and already-upgraded states explicit to the user.
• Record the expected result for expired and repeated purchase attempts.
LATER
• If the checkout-to-entitlement path carries material business risk, consider a separate source-level evidence review in a safe test environment.
6. EVIDENCE-LIMITED CONCLUSION
The illustrative materials prove only that one normal sandbox journey reached a success screen. They do not prove that entitlement persistence, repeat handling, account isolation, or production behavior is correct.
The next useful decision is therefore narrow: run the clean-session, interrupted-return, and second-account tests before expanding the review to the rest of the product.
