The context struct is focussed on restoring state when the context is exited. So I can get the op that the context will return to (cx_u.cx_blk.blku_oldcop) but not the first op that was executed in the context. Right?

Um, blku_oldcop points to the same COP (control op) that PL_curcop did just before block/sub entry, ie it's the last nextstate op that was executed before the block/sub was entered, and likely contains the value of the line number just before the block/sub start.
