Every risk method, standardised
670 methods across hazard science, exposure, vulnerability, loss, catastrophe, financial, sovereign, systemic, climate, health, cyber and assurance, each with a stable ID, an honest implementation state and the standards that govern it.
23 method fabrics
Every quantitative method the index and its platform may use is registered once, in one fabric, with a stable capability ID; a title is display text only.

What is implemented
169 capabilities are bound to hand-written scientific kernels with golden-value tests in Python, Julia or R. Every capability is release-held, with a supported claim level of integrated.
- Connected
- An existing governed engine path is available; specialist physics still needs validation for the context of use.
- Reference implementation
- Transparent reference mathematics for diagnostics and parity, not institutional-grade calibration.
- Adapter required
- Registered; an execution adapter is still to be built. Requests fail closed.
- Specialist model required
- Needs a specialist domain model. Requests fail closed rather than fabricate an output.
- Data required
- Needs governed data that is not yet available. Requests fail closed.
What every method must carry
The same contract applies to an NXS-GRX (canonical data, provenance and risk) index, a custom index in Index Studio and a model run in Model Lab.
- 证据
- sealed RiskDataCut for data-grounded execution; source release and exact-record lineage; rights/purpose decision; chronotope; model/method version; uncertainty and applicability evidence
- 不确定性
- aleatory where applicable, epistemic, parameter, model-form, data, scenario
- Verification and validation
- verification, calibration or justification, validation or benchmark, applicability, reproducibility
- 成果

What registration does not mean
- Capability registration is not model execution, calibration, observation, validation or assurance.
- CONNECTED means an existing governed engine path is available; specialist domain physics still requires context-of-use validation.
IMPLEMENTED_REFERENCEmeans transparent reference mathematics exists for diagnostics/parity, not institutional-grade calibration.SPECIALIST_MODEL_REQUIRED与DATA_REQUIREDfail closed rather than fabricate outputs.- Cryptographic integrity proves the network's own records relationships, not scientific truth.

Propose a method
New methods are registered with a stable ID, a hand-derived golden test and their evidence obligations before any page uses them.
状态
The Global Risks Index 的方法、结构和定义为预备性工作草案（2026），供审阅和评论，不供实施。在从受治理的证据截取中发布版本之前，不会出现任何数值；届时数值将附有区间、类别、来源及其更正途径。模拟器以您选择的数字运行已发布的方法，绝不显示 NXS-GRX 数值。
NXS-GRX 不是什么
NXS-GRX 是研究和风险分析信息。它不是信用评级或 ESG 评级，不使用任何评级尺度；它不是金融工具的基准，不是官方统计，不是紧急警报或官方分类，也不是建议。不得用于评估自然人。风险等级是已发布尺度上的区间，绝不是对国家或个人的排名。
机构与来源
The Nexus Consortium is stewarded by three independent not-for-profit institutions: The Global Centre for Risk and Innovation (GCRI), through GCRI US in Washington, DC and GCRI Canada in Ontario, with GCRI Canada as Lead Institution, Consortium Secretariat and lead contracting organisation; The Global Risks Forum (GRF); and The Global Risks Alliance (GRA). Technology, infrastructure and service providers work with the Consortium at arm’s length under written agreements, like every other external party in the public-private-planet model, and hold no role in its stewardship.

Avis en français
La méthodologie et les définitions du NXS-GRX sont un projet de travail préparatoire (2026). Le NXS-GRX est une information de recherche et d’analyse des risques : ni notation, ni indice de référence financier, ni statistique officielle, ni alerte, ni conseil. Les classes de risque sont des bandes sur une échelle publiée, non des classements.
