# NXS-GRX

NXS-GRX, the canonical data, provenance, risk and federation system of the Nexus ecosystem: purpose, rooms, inputs and outputs, areas, standards and boundaries.

**NXS-GRX** is one of the twenty systems of the Nexus ecosystem: the canonical data, provenance, risk and federation system. It is described here as a system of the ecosystem, with its purpose, its rooms, what it receives and provides, the areas it serves, the standards that apply and its boundaries.

Earlier pages may use the retired name `GRIx`.

## Purpose and context

Risk index methodology and risk data products. Its domain is governed data, ontology, evidence, fusion, risk products and correction. A typical setting is a national water-energy-food-health-biodiversity evidence and risk-product portfolio.

## What it is the authority for

| Record             | What the system must keep                                                                  |
| ------------------ | ------------------------------------------------------------------------------------------ |
| source release     | Record rights, temporal coverage and source lineage.                                       |
| ontology release   | Validate mappings, units and entity identifiers against one release.                       |
| fusion recipe      | Preserve conflicts, dependence assumptions and contributing records.                       |
| quality envelope   | Distinguish absent, stale, disputed and measured quality.                                  |
| correction lineage | Propagate source corrections to dependent cuts and products without rewriting old results. |

## Rooms and areas of work

Every system has ten rooms: eight shared rooms, which work the same way across systems with this system's domain, and two specialist rooms.

| Room      | Kind       | Purpose                                                                                                                                         |
| --------- | ---------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| Station   | Shared     | The system's home: posture of the system's own records, freshness, refusals and next actions; never a summary of another system's truth         |
| Mission   | Shared     | Mission and task work for the system's domain, linked to Universe missions and Project OS plans                                                 |
| Builder   | Shared     | Composition of the system's artifacts and configurations from admitted packages (NXS-STU, NXS-FAC and NXS-NXQ boundaries apply)                 |
| Maps      | Shared     | Spatial views of the system's records and NXS-GRX products, under the boundary licence gate                                                     |
| Data      | Shared     | The system's datasets, sources and lineage as NXS-GRX products or system-owned records                                                          |
| Commons   | Shared     | Shared methods, standards, templates and reusable artifacts, including Nexus Standards (NXS, a programme of the Nexus Consortium) participation |
| Reports   | Shared     | Reports and editions built from the system's evidence, with cutoffs and correction history                                                      |
| Knowledge | Shared     | Institutional knowledge, records, runbooks and learning linked to NXS-HUB                                                                       |
| Fusion    | Specialist | Records: fusion recipe, fusion case, mapping decision, fusion run, canonical product version                                                    |
| Cascades  | Specialist | Records: dependency model, propagation mechanism, shock definition, cascade run, cascade product                                                |

## Inputs

What it receives, and from whom. Each interface carries its context (estate, tenant, workspace, purpose, jurisdiction, time and place) and is checked under the policy authority.

## Outputs

What it provides, and to whom. Consumers read projections; the system stays the authority for its own records and their corrections.

## Interfaces with other systems

Beyond its interfaces, it relies on fact families owned elsewhere: semantic root (the ontology fabric); context history root (the time-and-place context fabric); capability and package registry ([NXS-NXQ](/organization/systems/nxs-nxq.md)).

## Standards that apply

Every record of the system is identified through the UNI identifier fabric of Nexus Standards (NS-1), and its public name follows the Nexus Standards naming rules. The areas it serves reference these external standards; naming a standard records where it is referenced and is not a claim of certification, accreditation, conformance or endorsement.

## Governance boundaries

Policy authority for the system sits with [NXS-NSF](/organization/systems/nxs-nsf.md); identifiers come from the UNI identifier fabric. The system exports read projections and commands through typed contracts, and no other system writes its records.

It does not own, and never stands in for:

* warnings (NXS-EWS)
* anticipatory action (NXS-AAP)
* decisions (NXS-DSS)

**Method boundary.** Fusion must account for correlated sources and incompatible supports. Preserve alternative hypotheses and uncertainty; distinguish causal hypotheses from statistical associations and report cascade stability assumptions. Do not flatten observation, inference, prediction and simulation into an unqualified truth value.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.therisk.global/organization/systems/nxs-grx.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
