Q1: What order do a Security effect, "when ... performs a security check" effect, and "when a card is removed from ... security stack" effect activate when they trigger simultaneously upon a security check?
Security effects take precedence for activation. Upon a security check, a Security effect will immediately activate without pending activation. For other triggered effects, the turn player activates their effects first.
Q2: Can I use this card's All Turns effect to place either my Digimon or my opponent's Digimon as the bottom security card?
Yes, you can.
Q3: Does this card's <Partition> also trigger when this card's All Turns effect is used to place this card itself as the bottom security card?
No, it doesn't trigger.
