Independent photon reference field apparatus

Separately made contained photon source and primary characterization/reference transfer hardware with caller-matched photon spectrum.

Discovered · unresearchedClosure: OpenInventory incomplete

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
"Not the microfocus source under construction or final survey detector; creation and spectral/dose response realization remain physical frontiers."
