1. Identify without ambiguity
We retain the complete model, its written variants and any regional suffix. Similar-looking references are never merged merely because they resemble each other.
2. Connect the part to evidence
Compatibility must appear in official documentation, support material or a manufacturer listing. A third-party shop can help locate a product but cannot establish fit on its own.
3. Show the limits
Checked regions, explicit incompatibilities and the verification date remain visible so that you can decide from the same facts.
