# Visual BOM Brief

## Goal

Create a reference-member visual BOM that helps a reviewer see the build system
without implying fabrication authority.

## Required Items

- Reference soundboard blank with measurement points.
- Rim and end-block stock.
- Bridge template set.
- String set or individual string samples.
- Crown measurement fixture.
- Humidity and temperature logger.
- Reviewed DXF/CAD screenshots once available.

## Caption Policy

Generated or speculative imagery must be captioned:

`CONCEPT ONLY - fabrication authority is reviewed DXF/CAD or measured template.`

## Layout

- Left: reference member plan view with bridge corridor highlighted.
- Center: validation tools and hold points.
- Right: blocked compact and bass family members with reference-gate warning.

Do not include private family/media/archive contents. Do not use generated
images for dimensions, bridge spacing, bracing, string path, or crown.
