`am3352-four-layer-dogbone.zip` contains the completed source, compiled site and validation reports.

Circuit JSON SHA-256: `{sha}`.

Build: zero native DRC errors. Independent copper audit: all 138 nets connected, zero clearance violations. All via annuli have at least 0.1 mm clearance from SMT pads on both faces, including same-net pads. Independent DDR validation: all 19 groups pass, including used via travel. See the included README for verification scope.
