Design Blueprint: The Step Is the Accuracy

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24119608): Where no refractionist is available, wearers can be offered trial lenses and asked which is clearer - but the fineness of the set decides in advance how good the result can be. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
