Scope and basis: Original proposed engineering methodology; no empirical effectiveness claim or external tool contract is asserted.

## Goal

Ensure a screenshot or browser inspection used to validate a coding change actually reflects the intended build, route, account state, and data fixture.

## Prerequisites

Have the acceptance scenario, the intended application instance, and authorized test data. Keep screenshots free of unrelated personal information and credentials.

## Steps

1. Identify the exact route and scenario to inspect, including required query parameters, locale, viewport, and account role. Record only the context needed to reproduce the observed behavior.

2. Confirm that the browser reaches the intended build or preview instance. Check a nonsecret revision marker or another project-supported identity signal rather than relying on the tab title alone.

3. Establish the required data state through the supported test setup. Distinguish a seeded fixture from live content and verify that the element under inspection belongs to the intended record.

4. Perform the relevant interaction and capture the resulting state. A screenshot taken before submission cannot establish what happens after a successful save; connect each observation to the action it follows.

5. Repeat a targeted observation after the final code change when earlier evidence became stale. Exercise a wrong preview URL and an outdated fixture in a controlled check to verify that the protocol notices the mismatch.

## Expected result

The visual evidence has a clear scope: a named scenario on a known artifact with identifiable fixture conditions. A reviewer can reproduce the observation and understand what it does and does not establish.

## Limits and test basis

This is an original validation protocol with no browser session claimed. A visually correct state may still conceal accessibility, persistence, or server-side failures. Add the appropriate nonvisual checks when those behaviors are part of the acceptance criterion.
