NXS-FAC
NXS-FAC (blueprints, builds and signing) is the software factory: where code, models and pipelines are built, tested and released with provenance, so that what runs in production is what was reviewed.
The workspace for NXS-FAC.

NXS-FAC serves these platforms.
Unreviewed changes are how trusted tools go wrong.
NXS-FAC is defined in system profile NRS-S16 of the Nexus Standards. Analytical software used in decisions must be traceable from source to running artefact. Supply-chain integrity practice (signed builds, bills of materials, reproducible builds) ensures that a release is what its reviewers approved.
- Signed, reproducible builds.
- Software bills of materials.
- Tests and review gates before release.
The standards a design like this is read against.
| Reference | Relevance |

| NIST SSDF (SP 800-218) | Secure software development practices |
| SLSA | Supply-chain integrity levels |
| SPDX | Software bills of materials |
What it exchanges with the other systems.
- Releases run on NXS-COR (compute, nodes and runtimes).
- Applications assembled in NXS-APP (application catalogue and lifecycle).
The ten rooms of NXS-FAC.
NXS-FAC has the eight rooms every Foundry system shares, set to its own authority, and two specialist rooms, Builds and Releases. Each is described by the work it is designed for; the public register records NXS-FAC as declared, not deployed.
| Room | Kind | Designed to |
|---|---|---|
| Station | Shared | Operate, inspect and correct authoritative domain posture for blueprints, Builder operations, code and artefact generation, verification, builds and signing |
| Mission | Shared | Coordinate bounded objective-oriented intelligence and human handoff for blueprints, Builder operations, code and artefact generation, verification, builds and signing |
| Builder | Shared | Design, engineer and prepare governed changes and artefacts for blueprints, Builder operations, code and artefact generation, verification, builds and signing |
| Maps | Shared | Inspect and compose spatial, temporal and world-model intelligence for blueprints, Builder operations, code and artefact generation, verification, builds and signing |
| Data | Shared | Work with data, ontology, Chronotopes, graphs, scientific methods and risk for blueprints, Builder operations, code and artefact generation, verification, builds and signing |
| Commons | Shared | Work with policy, law, standards, clauses, obligations and assurance for blueprints, Builder operations, code and artefact generation, verification, builds and signing |
| Reports | Shared | Compute, model, synthesise and visualise governed analytical products and reproducible reports for blueprints, Builder operations, code and artefact generation, verification, builds and signing |
| Knowledge | Shared | Work with institutional memory, records, citations, runbooks and learning for blueprints, Builder operations, code and artefact generation, verification, builds and signing |
| Builds | Specialist | Operate Factory’s source-to-artefact build and verification lifecycle |
| Releases | Specialist | Assemble, review, sign and manage release candidates and governed release bundles |
Authorised projects only.
Access requires an authorised project with an accountable owner, data terms and a review plan. Enquiries go to the contact form.
Where NXS-FAC subjects are taught.
Risk Academy, led by the Nexus Consortium, teaches the subjects practised in NXS-FAC in these disciplines; the Global Centre for Risk and Innovation (GCRI) links to the Academy as a partner and does not provide its courses.

Questions and answers.
Is the system available now?
Bring a method, a dataset or a question.
Information and enquiries are open today. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
