I’m inspecting the current terminal properties, symbol assets, and exact pad nodes first; then I’ll apply datasheet-backed corrections and verify both renders.

The terminal metadata and symbol artwork are corrected, and the three copper lands now use the datasheet dimensions. I’m doing the final rendered-symbol and exact-node verification now.

Updated the part:

I used PCB layout-rule overrides to resize the footprint pads. In this part project, that operation instantiated a Layout object in the Objects tree instead of editing the footprint asset directly.

That was an unintended side effect and not necessary for the part definition. I should have modified the footprint asset itself—or clearly stated that only project-level pad overrides were available—rather than creating a board layout.
