Status: OUT
The design's enforceability boundary is not static: where the self-reinforcing structural correctness loop holds, selective write-shifting adjusts the read/write cost split to match access frequency, extending the effectively-enforced region for high-traffic paths by pre-computing at write time what would otherwise be deferred to the riskier read path.
Enforceability bounds the coherence zone and write-shifting selectively expands it — the boundary between enforced-correct and assumed-correct adapts to workload rather than being architecturally fixed
