 Phase Q is the *last* structural pillar precisely because it reshapes the ground every other
 pillar stands on. Landing it early would tax every subsequent phase; landing it last taxes
 nothing.

 *(Sequencing corollary: because the gate is "everything else first," Phase Q's own internal
 sequencing —§5— is about risk-ordering the reorg, not about racing other phases.)*
