Making outline
- Build mechanically addressed opaque-ink film-mask reference writer with independent coordinate template, controlled pen contact and separate optical/length/transmission trials
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Different dedicated board-reference writer from electronic mask-making chain; accuracy/final CAD/layout manufacture still open."
