Design Blueprint: Flour Beetle Sieve Mesh

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24121738): Sieving is the traditional household response to flour beetles, performed with whatever sieve the kitchen holds. This study computes stage-by-stage removal for the red flour beetle using stated stage widths (egg 0.35 mm, young larva 0.5 mm, older larva 0.9 mm, pupa 1.1 mm, adult 1.2 mm), a logistic retention curve, and a starting contamination of 98 insects per kg across stages. A common 1.0 mm kitchen sieve removes 94.3 percent of adults but only 17.2 percent of all stages, and effectively no eggs. A 0.6 mm mesh removes 39.6 percent overall; 0.45 mm removes 58.8 percent, including 19.8 percen 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.
