Abrogail Thrune's counterassassination security model has also obviously considered an attack on Abrogail inside her Palace's Forbiddance; there's just way too much weird shit in Golarion for it to be realistically possible to keep everyone out of a place.

The advantage to the attacker, in this case, will be that Abrogail Thrune will be less prepared than when she ventures outside, without a dozen protective spells that are too bothersome or too expensive to constantly redo.  She also will not be able to immediately Dimension Door or Teleport away, because of the Palace's Forbiddance.  Gorthoklek cannot immediately Greater Teleport to her side.

The attacker's primary disadvantage is the Forbiddance; and the security model assumes that the attacker's primary goal is getting outside of the Forbiddance, carrying a gem with Abrogail's soul or her head still wearing the Crown (or both).

Permanent walls of force are Very Expensive.  One-time walls of force, rather less.  If the Status on Abrogail indicates that she is severely injured or dead while inside the Palace, multiple layered walls of force and several other complicated measures will spring up to enclose the Palace Forbiddance almost immediately.  Other security measures are then invoked with the aim of sweeping the enclosed volume inside the countermeasures before they run out of time and come down; against an attacker determined to hide and ride out Cheliax's supply of temporary enclosures.  (An attacker trying to hide probably has the Queen's soul gem; the Crown should be impossible to hide.)

Of course Security has not failed to consider the possibility of the Forbiddance itself being taken down, by a Dispel from Nefreti Clepati or a Mage's Disjunction.  Could the attacker also have cast a Teleport Trap before then, in case Abrogail Thrune tries to just Teleport right out?  If it was some other sovereign being targeted, then maybe, but a Teleport Trap allows both a Will save and Spell Resistance; an 8th-circle sorcerer wearing the Crown of Infernal Majesty is probably fine here.

Again the details of measure and countermeasure would be lengthy; but one very pragmatic countermeasure is that if the Palace Forbiddance goes down while Abrogail is inside it, Gorthoklek teleports to her location and then scries for Aspexia Rugatonn.
