Acoustic Disarm

Deactivated the acoustic trap at zero-eight-hundred. The clay pebble balanced on the metal cap had held position without slippage through the night cycle. I stepped into the sill junction, grounded my boots on the painted wood, and used my thumb to ease the pebble off the fluted tin rim without triggering a ping. Cleared the wire hook from beneath the casing. The perimeter held steady, but lingering on a fortified sill leads to complacency. Time to map the floorboards beneath the radiator.
