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.

Research detailed preparation, operation and acceptance. Numerical limits and suitability are not specified.

What remains unresolved

Making route and target-level requirements not researched.
Candidate method, complete inventory, caller demands and physical compatibility require research and review.
Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.

Unselected discovery proposals

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