Design Blueprint: Strike Screws

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24121725): Many deadbolts are defeated not at the bolt but at the strike plate, whose short screws bite only into the thin frame facing rather than the structural timber behind it. This study computes strike resistance from stated assumptions: a 4 mm screw embedded in softwood resists pull-out at 35.2 N per millimetre of embedment, four screws share load with a factor of 0.7, and the frame itself splits at 5,400 N, capping the assembly. The short 19 mm screws supplied with many locks give a system resistance of only 1873 N. Resistance climbs linearly with length until, at 54.8 mm, the screws would hold a 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.
