Oh, I was hoping you have some left :/
All right, answers:
1. nothing, biofeedback will help you during dumpshock, nothing else, as far as I think
2. you didn't

the target was 4
3. there was no agents back in the redwire (if I recall correctly, it was some month ago

, and as far as the common appas suit, please name them - and name three of them only
as for the options. like I said some time earlier, power off is one of the options, someone could also log in from AR and stop the BTL program, and someone could hack his way in or just wait until the program ends or you loose conscious due to dehrydration and starvation.
How this had happened? Well that's the difference between AR and VR. in hotsim, you're withing the node, regardless if this is user/security or admin account you are withing the node and are receiving directy to the brain the reality as designed by the node's sculpture.
This is far from the corporate commlink - this is an off the shelf Alice's private commlink, custom modified by Dean running hostile BTL program, that took over your mind.
the dumpshock rarely kills (not if this is the only wound you get), this is just 5P resisted with biofeedback
