Indeed, you did not spoil anything.
The thread [POSSIBLE SPOILER] Dies Irae - high lab totals has the problem, that it cannot discuss the conditions of the lab total required and possible in DI The End of Time, without spoiling that campaign. So I took its discussion with Lebo77 - on his request - offline soon.
Anyway, The End of Time does not handwave the lab task in question.
Of the dangerous options for lab totals, the thread [POSSIBLE SPOILER] Dies Irae - high lab totals has AFAICS only addressed in passing the loop-hole in Covenants p.121 Magic Items in Laboratories, which allows an arbitrary number of different effects from enchanted items to add their points to the same lab Specialization, and as balance uses lab Warping added at SG's discretion.
Quite.
Cheers
