Theory 1: What if the Ark is a counter to the Halos activation, for example the Halos affect everyone but the Flood, so maybe the Ark is a weapon similar to the Halo except it destroys the spreading flood, maybe the forerunners used it to defend themselves against the infestation but failed to activate/complete it on time.
Theory 2: The Ark is a program or structure that holds the power to cancel the activation of the Halos. Think of it as a last result, the forerunners were genius so maybe the thought of the possibility of the Halos powers falling into the wrong hands so they created a program or key to counter the programming of Halo, as an abort system.
Discuss :D
