Finished: I added datasheet-aligned pin descriptions/types, restored MH1/MH2 as the canonical active mounting holes, and cleared the mounting-hole review issue. I also added a short Part Review Notes document so the project-documentation DRC passes.
Open items:
- The imported KiCad footprint asset text still contains legacy H1/H2 entries, but ERC/DRC no longer flags them as active issues.
Checks:
- ERC/DRC/component review: no ERROR/WARNING/OPEN/UNCERTAIN checks remaining.
