Resin recession is where the resin moves away from the copper plating when it
gets hot from HASL or assembly processing.

Hole wall pullaway is where the copper moves - usually due to lack of
adhesion to the hole wall - again when the hole is exposed to heat.

Neither one of these conditions is considered a "defect".  Just an indication
that the board is not at optimum conditions.
