Footprint/package cross-check

The footprint has eight SMD pads and SO-8 style silk/fab geometry with pin-1 indicator. The visible body/silk dimensions are consistent with narrow SOIC-8 style geometry, and the datasheet package is SO-8 / SOIC narrow, JEDEC MS-012. No footprint pad numbering mismatch was found from the available layout data.

Mismatches / cleanup items

No critical pinout mismatch found.
No critical footprint/package mismatch found.
Datasheet URL was already set; no update was needed.
Symbol terminal descriptions are implicit in the terminal designators (S_1, S_2, S_3, G, D_1, D_2, D_3, D_4), but each terminal's Pin Type property is still set to Unspecified. For better library quality, set Source/Drain/Gate pin descriptions and electrical pin types explicitly.
MPN formatting differs slightly: project uses SQ4435EY-T1_GE3, while datasheet ordering line shows SQ4435EY-T1-GE3. This appears to be separator formatting rather than a functional mismatch, but distributor/manufacturer ordering should be checked if exact orderability matters.
