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

Canonical reuse assessment
"Manual address/data panel supplies logic bits only; this apparatus adds real field impedances, isolation boundaries and fault loads. References and making inventory remain open."
