I'm a bit confused about how disorder triggers work.
Triggering a Disorder: Each disorder is triggered by certain
circumstances, as determined by your GM. Example triggers are given with each listing; disorders are also triggered by traumas ▶223. When a trigger condition occurs, make a WIL check; if you fail, the disorder is triggered. When activated, the disorder directly affects your actions and what you can and cannot do, as fitting the affliction. The GM may direct your character’s behavior or apply modifiers as they see fit. The episode lasts for as long as your character is affected by the triggering condition. [...]
The cross-referenced section on traumas says:
TRAUMA EFFECTS [..] Disorientation: Each time you suffer a trauma, make an immediate WIL Check (modifiers apply). If you fail, you are temporarily stunned and disoriented by what you have experienced. You must expend a complex action to regain your wits. Additionally, if you have a disorder triggered by that type of stress, it is activated by the trauma.
Many of the disorders are triggered by some or multiple of the standard stress categories: alienation, helplessness, the unknown, and/or violence.
Does any exposure to these things cause a potential disorder trigger roll? Or only if the exposure generated enough stress to create a trauma? If a person with a relevant disorder is traumatised by a relevant trigger, do they have to make two trigger tests (once for exposure, once for being traumatised?) Or does being traumatised by a relevant trigger automatically trigger the disorder effects? If so, does that mean that the disorder will remain in effect until the trauma is healed because "The episode lasts for as long as your character is affected by the triggering condition"?
Many disorders have Effects that require WIL checks. E.g. Autophagy requires a WIL Check or you begin to consume one of your limbs. Are these WIL checks a second roll made after the disorder has already been triggered (as a second chance or temporary relief), or is the WIL check mentioned in the Effect text the same as the WIL check made to see if the disorder triggers in the first place? I'm not sure why the disorders seem quite inconsistent concerning which ones mention WIL checks in the Effect and which ones don't.
In the specific case of Body Dysmorphia, the effect is a -30 penalty on Resleeving Stress Tests. Let me check if I understand this correctly. When someone with Body Dysmorphia resleeves, they first make an Integration Test to see how long it takes them to adjust to the body. Then they would make a WIL check to see if Body Dysmorphia is triggered (since it's triggerable by Resleeving). Then they make the Resleeving Stress Test, possibly modified by the Body Dysmorphia. If they are traumatised by the stress incurred from the Resleeving Stress Test, that would presumably automatically trigger Body Dysmorphia (since it's a trauma arising from the disorder's trigger condition). But apart from the deeply unpleasant personal experience, that might not apply any further mechanical penalties (since the Resleeving Test is now in the past) unless the GM decides that further penalties are called for. Does that sound right? Have I messed up any rules points?
