Trap disarm puzzle

A brass-cased pressure plate under a flagstone. Ease the release pin along its groove before anyone steps on it.
Someone lifted this flagstone to hide a pressure housing beneath it. A grooved channel runs from the trigger to the release catch, and a steady hand can walk the catch home.
The channel is wide and the springs are tired. Take it slowly.
