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
- Package a near-field transceiver and separately formed copper loop antenna; tuning, matching and enclosure losses remain open
- Develop a bounded process specification and establish earlier availability of every listed physical prerequisite.
- Make trial pieces, measure interfaces and performance with independently established references, and reject incompatible outputs.
What remains unresolved
- Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.
- Selected wirebond package hypothesis does not establish flagship I/O density, power delivery, size or thermal capability; flip-chip bump/underfill architecture is a separate OR alternative requiring its own complete inventory.
