Does loss-structure presence (discrete, ambiguous, role-based, or none) add real...

The dialogue transformed the proponent idea from a main-effect doctrine ('some emptiness is grief, not insight') into a moderator hypothesis ('loss-object presence is the variable that disambiguates after-use numbness'). The challenger's weak-specificity objection was decisive against causal priority: nearly every modern practitioner can name a loss, so loss-presence alone routes everyone and therefore routes no one. The proponent conceded causal priority, conceded Bonanno's resilience finding, and conceded that supported grief-transformation is a large class, not an edge case. What survived is narrower and not absorbed by the challenger's routing model: the loss-object is the lens that tells you what after-use numbness is made of, since method-generated quieting and unmourned grief look identical until you ask whether a concrete loss predates the practice. The challenger accepted this as a genuine transformation and widened the open question from loss-object to loss-structure.
