Define spins "freely". Looks like to me you had the WP fail, locking up or at minimum not spinning as well as it should causing the belt to rub through the aluminum. how did you not hear or feel this happening. Definitely not a NST pulley issue imo looks like negligence.

spins freely: no binding, stuttering, or drag felt
water pump was replaced 20k miles previous.
coolant temp in AM never exceeds 80c; pm never exceeds 85c
pulley temp after 10mi city/15 mi hwy is 69.2F measured with laser thermo.

PULLEY IS GARBAGE!!!
