# KiCad Video Demo Evidence

This deterministic package records structural and visual evidence for the official
KiCad `video` demo board at the immutable `10.0.0` tag. The design is an official
KiCad project distributed under GPL-3.0-or-later. It is not Resin-authored, and
this package does not claim that Resin designed or fabricated it.

The source board and root license were downloaded only from pinned raw URLs in
KiCad's official GitLab repository. Their expected hashes are checked before a
build can succeed. `metrics.json` comes from parsing the unmodified board with
the committed Resin native PCB parser. The four SVG previews come from the
committed Resin native SVG renderer and intentionally contain only the selected
side's copper and silkscreen plus `Edge.Cuts`; back previews are mirrored for a
natural bottom-side view.

The package also retains a completed KiCad CLI DRC report and a time-bounded
Resin-native family record when those add-ons have been collected. Those files
do not assert DRC acceptance, fabrication acceptance, or that the design was
fabricated. Native family timeouts remain explicit.

## Contents

- `source/video.kicad_pcb`: byte-exact official source board.
- `LICENSE`: byte-exact KiCad root GPL version 3 license text.
- `metrics.json`: parser identity, source hash, and exact structural counts.
- `provenance.json`: pinned source, licensing, renderer, layer, and claim scope.
- `previews/`: paired light/dark front/back SVG renders.
- `checks/`: optional bounded native evidence and its complete KiCad CLI report.
- `SHA256SUMS`: SHA-256 for every other file in this package.
