Qualitative signpost review · no probability assigned
Bounded observation
The US Bureau of Industry and Security rescinded the tiered AI Diffusion Rule before its compliance date while simultaneously issuing stronger guidance on PRC advanced-computing chips, AI-model training and diversion risks. The same action weakens evidence for a universal country-tier stack while strengthening evidence for adversary-specific compute separation.
Trigger threshold
Move to observed when at least two core operating stacks such as compute, cloud, payments or media become practically non-portable across major blocs under implemented rules.
Counter-indicator
Rescission removed a proposed broad country-tier regime and explicitly retained access for trusted partners, so this event is not evidence of complete bloc separation.
Update criterion
Review the replacement rule and enforcement data; escalate if controls expand from named adversaries to routine interoperability, downgrade if certified partner routes preserve practical portability.
