The floor looked acceptable before the light changed.
Then side light hit the surface.
A few scratch lines became visible near the edge. The open area still had shine, but the reflection was not clean. The problem looked like a final polishing issue, but it likely started earlier.
What the light showed
Side light made the scratch direction easier to see.
The marks were not random.
They followed the earlier grinding path, which means the floor still carried scratches from a previous step.
A final resin pad can make the surface brighter, but it cannot always remove scratches that should have been handled before resin.
Why the edge looked worse
The edge did not match the open floor.
That is common.
Edges often use different pressure, smaller tools, and a different working angle. If the edge sequence is weaker than the main floor sequence, the border shows the mistake first.
What should be checked before continuing
The next move is not automatically a finer resin pad.
First check whether the scratch is from the metal step.
Then check whether the hybrid transition was strong enough.
Then check whether the edge tool followed the same logic as the open floor.
If the scratch is still from the metal stage, the floor may need transition work before polishing continues.
