Origin:  Synthetic fixture generated by `zaptrace.export.kicad` on 2026-07-27
Purpose: KiCad corpus gate test fixture — USB hub structural fixture with independently valid supporting sheets
Toolchain validation: `kicad-cli 10.0.5 sch erc --severity-error --exit-code-violations`

These synthetic schematics are not derived from a real-world product. They are
minimal, parser-valid KiCad fixtures for deterministic structural and external-tool
grading. They do not claim electrical completeness or fabrication readiness.
