Pads for C7334, a nostuff component (used during development or removed due to it not being needed in production). One pad is ground and the other is PPBUS_S5_HS_COMPUTING_ISNS, a 12.8V power rail. Touching both temporarily shorted this rail to ground, causing the spark.

It should work fine still, since nothing is permanently shorting the voltage to ground, so reassemble it and try this out :)
