CRs in Velketor's Labyrinth

[Tirano]

Hello fellow rogues!

I was doing a CR in Velketor's Labyrinth over the weekend down in the lower dogs for a few friends that found themselves in a snag. It ended up being a success but it left me with a few questions on some game and class mechanics that I've been pondering.

1. There are a couple types of traps in lower dogs. AFAIK, there are mob spawn traps and AOE dispel traps. I thought I saw a physical damage trap too. Which of these traps would break sneak/hide?

2. Do the traps in Velketor's Labyrinth reset after they are triggered? I think I was able to sneak through an area where a mob spawn trap was because I saw a tight pack of like 10 mobs. They were not pathing. They were piled on top of each other like in a bard swarm. They were just hanging out waiting for their next victim. Perhaps I was able to not touch the trigger or the trigger would not reset until those mobs were killed.

3. Does disarm trap drop hide?
