Impersonal Closure Framework: Cross-Domain Invariance: The Closure Stack Under Scrutiny

Cross-Domain Invariance (ICF-4) provides a synthesis layer for the Impersonal
Closure Framework. It proposes that, across domains under high scrutiny, systems
converge on a small set of stable operations that regulate knowability and exposure.
The paper introduces the closure stack: a coupled structure in which (i) Descriptive
Closure (ICF-0) limits further explicitness, (ii) Decision Displacement (ICF-1) converts
decisive ownership into procedure and reversible steps, and (iii) Audit Substitution
(ICF-2) replaces understanding with auditable artifacts. The stack is not presented as
pathology or conspiracy; it is presented as a survivability response to asymmetric
penalties under review. ICF-4 defines cross-domain invariance claims, specifies
observable translation traces, and provides minimal validity conditions to keep the
analysis structural and non-prescriptive. The document does not name institutions,
does not recommend interventions, and does not describe tactics for evasion or
manipulation. Its purpose is cumulative: to enable citation and comparison of how
systems co-produce ‘what is real’ as ‘what is defensible’ when full legibility is
unaffordable.
