Unified Causal Registration
Abstract
The two frozen causal transitions are registered on the unified arena for import-closure consumers.
The observation-intervention and intervention-counterfactual separation theorems share the canonical unifiedArena under the causal-unified-transitions catalog identity.
Each occurrence uses its branch-local primitive bundle and faithful realization from UnifiedCausalAlignment. The cumulative three-readout analysis catalog is separate from these two theorem occurrences.
Importing this module makes both registrations persist with UnifiedCausalRegistration as their contributor. This module does not seal a root or declare an expected occurrence manifest.
