Maritime access
Sea access and ports
The strait, the approaches and the ports through which Taiwan imports almost all of its primary energy and ships its exports — read as access and cover, never as a naval picture.

Context, not targeting. A system record names published markers and published operators and states dependencies at the level a published institution does. It carries no facility-level capacity, vulnerability, protection or repair detail; the schema has no field for any of it.
Strategic systems 3 of 5 carry a system record; the rest are derived from the module’s published markers and say so. A record states what the system is, its dated current state, the supply systems and operators that belong to it, and what it depends on — with every dependency marked documented or assessed.
Strategic system
Semiconductor economy
The Hsinchu–Taichung–Tainan cluster that fabricates the majority of the world's most advanced logic chips — a concentration that depends on imported materials, imported energy and continuous power.
Transport network
East-coast connections
The east-coast cities whose road and rail links to the west are the module's published transport context — two markers, no system record yet.
Strategic system
Deterrence architecture
3 published markers, 1 supply system running through it.
Strategic system
Political / command
1 published marker, 1 supply system running through it.
Evidence and grading
- Documented
- A published source states this relationship.
- Assessed
- Vigil infers this relationship from the records; no source states it directly.
- Structural stub
- A record that establishes a system exists and names it, and carries only what it can support — line, basis, sources, review dates. Detailed research is not done, and the page says so rather than inventing detail.
- Confidence
- How well established Vigil considers this assessment to be. It is not a measure of how severe the situation is.
