USB-C A5/B5 are contacts, not EP. Datasheet pintable, KiCad
.kicad_mod, and embedded PCB pads join by pin identity. Missing
pintable skips; scalar pin_count is never an ERROR authority.
Add /api/library datasheet import and component GET/PUT with no exam.
Reorganize pytest into datasheet, library, schematic, PCB, and AF+AI.
Document Rust criteria (none chosen; no rustup) and coding conformity.
