Each mission (as defined in the Level Select menu) is made up of multiple game-task-nodes, each of which can be closed as you progress through the mission. For example, there's often an "introduction" node where you talk to some NPC and learn about the mission. Each mission ends with a "resolution" node.
The Jak II "All Missions" ruleset requires that you close the "resolution" node directly in order to consider the mission completed. In other words, you cannot close some other node further down the mission tree, and indirectly close the "resolution" task - often called a "Percentage Warp". Mars Tomb Skip in the Any% run is a notable example of one.
I added a check in this mod to determine if a "Percentage Warp" was used when a mission is completed. This ended up surfacing some interesting edge cases trying to apply the All Missions rules - a few missions have no true "end trigger" and can only be completed by closing the "introduction" node of the next mission in the tree.
Known cases:
- Beat Time to Race Garage (city-keira-delivery-resolution is only closed via stadium-board1-introduction)
- Attack the Metal Head Nest (nest-enter-resolution is only closed via nest-boss-introduction)
As a counterexample, Get Heart of Mar in Weapons Lab could also be closed in this way - death warping to start the Krew fight early closes castle-break-in-resolution indirectly via castle-boss-introduction. However, there is a proper end trigger that closes castle-break-in-resolution directly - killing the robots in the last room and entering the elevator.
