Geneva Drive is a Ruby library that turns long, fragile procedures into sequences of discrete, durable steps. Each step begins and ends at rest; failures resume where they stopped; retries do not double-run.

Named for the watchmaker's mechanism that converts smooth rotation into intermittent motion — one frame, one step, one tick at a time.
