One grammar from source to global reading
Global values aggregate the 195 profiles, weighted by population for human-centred domains and by exposure or output for economic and infrastructure domains, and read the global systems directly.

Four pillars, one composite, one coupled composite
A class is printed with its probability (share of Monte Carlo draws inside the class). Below 60% the adjacent class is printed too (for example High, 54% · Very high, 41%).

Where risk travels across systems and borders
The Coupling instrument types the dependency edges between ten systems and reports the coupled composite beside the standalone one.

The rare, severe end of the distribution
Exceedance curves, return-period losses and expected shortfall where loss can be modelled, plus a register of low-probability, high-impact risks.
Standing tail register
How risk moves to 2030, 2050 and 2100
Pathways editions project each domain under named scenario families as fan charts, never as single lines.
Calibrated probabilities, verified in public
Every Outlook model version publishes its reliability, Brier skill and ROC area against realised outcomes.

MethodFrom a detected signal to a briefing
Pulse and Outlook signals stop at an analyst gate; nothing is issued as a warning by NXS-GRX, and every handoff names the authority that decides.
End to end on the longest path: about 12.3 d of proposed target service levels, before the jobs that run with no fixed end. Gates wait for the people named; bars with a fading end have no fixed length.
