Teach-Your-Home Tripwires

Anything that moves the same way each time — a safe door, a jewelry drawer, a ladder — nudges the signal in its own repeatable way. Repeat the action a handful of times and the system learns that exact nudge. From then on it watches for it, with zero new hardware.

In the physics: Any repeatable mechanical change in the environment (safe door swinging, drawer sliding, ladder repositioned) produces a consistent, low-dimensional signature across CIR delays and Doppler transients. Controlled repetition makes that direction statistically separable from ambient variance — the perturbation defines its own subspace, which is exactly what LF2's poke-and-observe axis discovery is built to extract.
