Abuse and failure paths
Abuse: Export-control coercion, single-foundry dependence, hidden hardware access.
Failure: Geopolitical disruption, contamination, yield collapse, obsolete node.
Required exit and alternatives
Exit: Multi-node designs, stockpiles, repair, mature-node fallback, supplier diversity.
Portability: Portable designs, documented interfaces, substitutable components.
Interoperability: Open instruction sets and packaging interfaces where feasible.
Independent alternative: Mature-node survival stack and multiple geographic suppliers.
Emergency handback: Prioritize safety, identity, communications, and recovery hardware.
Disconfirming evidence
- Failed exit drill
- Unavailable independent alternative
- Retaliation for attempted exit
- Material portability gap
- Undisclosed common-mode dependency
Truth boundary
Static risk-governance record. It does not prove an operational service, market share, capacity, dependency, alternative, or successful exit drill.
Authority and record status
Responsible authority: National Engineering Directorate.
Static concentration-governance record; no operational alternative or exit drill is proven.
Revision date: . Public corrections may be initiated through the diplomatic contact route.
