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.

Making outline

Qualify physical contact/scale instruments against an earlier independent length master and record measurement uncertainty
Build or acquire each explicit earlier physical input; establish independent references and interfaces.
Make trials and accept only against the eventual caller specification; record uncertainty and rejected outputs.

What remains unresolved

Making route and target-level requirements not researched.
Full inventory, required quantities, process settings, numerical demand and suitability remain open.

Unselected discovery proposals

These are research questions, not published manufacturing dependencies. The seed combines alternatives, operating requirements and verification relationships.
