The design includes files originating from an older KiCad workflow; review schematic links, footprints, design rules, zones, and manufacturing outputs after any conversion or upgrade.
KiCad source files and project-specific libraries are the source of truth. Generated BOM, Gerber, assembly, and fabrication-house outputs are excluded from the repository; regenerate and verify them before manufacturing.
Temporary KiCad state, locks, autosaves, and backup directories are excluded by .gitignore. Board revision, tested KiCad version, manufacturing revision, and hardware/firmware compatibility still need to be recorded when provenance is confirmed.
