Design Blueprint: Hand-Pump Cylinder Sized to Well Depth

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24115140): A piston hand pump whose cylinder bore is chosen from the source paper's force-balance rule for the well's depth, so one operator's stated force lifts the full water column on each stroke. 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.
