Dashed = reconstructed · solid = calculated live
Longer-term context
Historical reconstruction before live collection; collected evidence thereafter
Earlier periods are reconstructed from historical source data. Once v2.1 live collection began, current-year statistics use collected observations and leave degraded or missing periods unscored.

LOADING CURRENT INPUTS
What could stress the system now?
Fourteen checks: five score-driving cases, six mapped HVDC links, two direction summaries and one extreme stress case
5 SCORE-DRIVING CASES
Types: reference incident · generation loss · regional import dependency · large load loss · physical HVDC context. "Not applicable" is a valid known state; "missing data" means a required input is unavailable. Color is only a visual guide.
Experimental, versioned model. The headline is a model-derived initial-disturbance margin, not a probability of grid safety and not an official Svenska kraftnät, Fingrid, Statnett, JAO or SMHI system state.
