X-ray resolution and contrast artifact

Independent known-geometry attenuation pattern and joint-defect reference specimen; discovery hypothesis, capability and compatibility unreviewed.

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

Assemble independently measured thickness steps, metal-space features and known-geometry joint witnesses
Detailed procedure and acceptance remain unresearched.

What remains unresolved

Manufacture, quantities, suitability and complete inventory remain unreviewed.
Current memory-first method needs source and compatibility review.
