Design Blueprint: Mouse Snap Trap Spacing

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24121534): Households are usually told to place mouse traps a short distance apart, but no spacing is ever derived. This study models a house mouse making 60 m of wall-following travel per night along a 24 m run of kitchen and store-room wall, with each baited snap trap drawing investigation from 0.6 m either side, an investigation probability of 0.55 per zone entry, and a capture probability of 0.75 given investigation. Because the mouse re-crosses the same wall many times a night, capture probability saturates quickly: a single trap on the whole run still gives a 0.735 capture probability per night, an 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.
