Diagram Archive

The visual archive has two different jobs. First, it preserves documentary evidence: original scan crops, crop metadata, page labels, and verification status. Second, it builds modern reading aids: clean redraws, annotated guides, and interactive tools that help readers understand what Steinmetz was showing.

Visual Workflow

1. Extract original page images from the source scan.
2. Crop figures and preserve an untouched original crop.
3. Store source title, printed page, figure number, crop coordinates, and checksum.
4. Clean contrast only in a separate derivative image.
5. Recreate vector forms when the geometry benefits from a modern redraw.
6. Add modern annotations in a clearly marked reconstruction layer.
7. Add ether-field annotations only as a separate interpretive layer.

The long-term goal is to place original scan crops, cleaned crops, vector recreations, annotations, equations, and concept links side by side for every important Steinmetz diagram.
