Design Blueprint: Weaving a Water Filter Cloth to a Stated Pore Size

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24119534): Woven cloth is the oldest filter medium in the world and still the one a village workshop can make for itself, but a filter is specified by its pore size while a loom is set by thread counts, and the translation between the two is rarely written down. 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.
