Use one comparison frame across every candidate
Use a comparison matrix built from observable fields: source match, variant, measurements, photo coverage, visible condition, current price components and policy questions. Do not reward an option for information it does not provide.
The result should expose trade-offs and uncertainty. A candidate with a lower item price may have weaker measurement evidence or a less clear shipping estimate, so item price alone cannot settle the comparison.
| Comparison field | Question to check |
|---|---|
| Source match | Does the destination still describe the same item and variant? |
| Measurements | Are the relevant dimensions readable and comparable? |
| Visual evidence | Do available images show the areas that affect the decision? |
| Current cost | Which components remain outside the item price? |
| Open questions | What information is absent or still time-sensitive? |
