3.2Domain posture
Each of the twelve coupled domains is read in words, not scored. The reading states where the regional evidence points; the coupling column names the dependency that carries risk across systems and borders.
| Domain | Posture at baseline | Coupling | Status |
|---|---|---|---|
| WAT | Shared rivers; Colorado River decision record of 21 August 202619; Mexican freshwater withdrawal 44.9% of resources in 20228. | WAT → ENE · WAT → FOO | Reported EQL 5 |

3.3Sector screens
All sixteen global sectors are screened on the same grammar as every national edition, so later editions can say what changed. The evidence column describes coverage of the baseline evidence, not the performance of the sector.
| Code | Sector | Baseline evidence | Exposure to watch | Evidence coverage |
|---|---|---|---|---|
| GS-00 | Cross-system | compound drought, heat and grid stress | dry, hot summer across member borders | PARTIAL |
| GS-01 | Water | Colorado River decision record19; withdrawal shares8 | low supply on shared basins | GOOD |
| GS-02 | Energy | electricity mixes and gas exports525 | gas supply; cross-border flows | PARTIAL |
| GS-03 | Food | cereal output in 202410 | drought and heat; trade | THIN |
| GS-04 | Health | age structure and life expectancy9 | heat and smoke load on services | THIN |
