i cant tell if you poured through or not... im just saying.
we poured a drive with paver strips through it, and that was one of the take away lessons. next time pour "footings" under the paver strips. i think maybe it was not enough interlock? thereby causing the pavers to shift in elevation a touch. that job was a holland stone paver.
one final thing.... it looks like when you stripped the forms you crumbled the concrete edge at the paver apron. i would say this was because you pulled the forms the next day or so later and when you were brooming (way too early) you pulled the cream into your rounded over edge. pulling the forms broke this cream back off.
if you get into the situation where you don't have an edge -- (hot and someone forgot it... or you broomed too early and filled your edge in with cream) take a chop saw (quickie saw, demo saw) and run it along the edge of the form. say 1/4 deep. it will cut that free and keep it clean when you strip.
