Design Blueprint: The Screen Sizes the Overflow

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24120033): A covered rainwater tank needs three openings to behave: an overflow that can discharge the design inflow when the tank is full, a vent that admits air as fast as water is drawn off, and mosquito screening on both, fine enough to exclude insects. 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.
