Morphology

tripwire = trip + wire (semi-transparent) = trip + wire

Metaphorical extension from the physical device: components are identifiable but the figurative sense (a small trigger for a larger reaction) requires pragmatic inference.

Etymology

Tripwire comes from the image of a thin wire that 'trips' a device when it is touched, and people use the word for events too: a small action can act as a tripwire that sets off a much larger reaction. So a tripwire here means a small trigger that causes a big result.
