Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.
Parts and Tools needed
No researched inventory yet. This is an unexpanded frontier; an empty list does not mean the item can be obtained directly from nature.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
Canonical reuse assessment
"Reusable operation tooling, not the apparatus that writes it; each copper layer needs actual pattern identity/quantity/registration. Pattern grade/fit unqualified."
