# V. Marketplace

#### Summary

The **Nexus Marketplace** pillar is the governed discovery, listing, and public-good marketplace layer of Nexus. It operates as a digital public goods marketplace, public-good software marketplace, digital public infrastructure marketplace, resilience software marketplace, API marketplace, developer marketplace, integrator marketplace, and implementation-support marketplace across the Nexus Ecosystem.

It makes digital public goods, digital public infrastructure tools, public-good software, APIs, connectors, dashboards, packs, workflows, developer tools, integrator pathways, opportunities, and support pathways discoverable across Nexus. It gives users one governed place to discover software, resilience software, climate resilience tools, disaster risk reduction tools, disaster risk finance tools, data tools, risk intelligence assets, providers, developers, integrators, implementation partners, and lawful support pathways.

## 1. Marketplace Identity, Purpose, Thesis, and Nexus System Function

### 1.1 Nexus Marketplace Defined

1.1.1 Definition. Nexus Marketplace shall be the governed discovery, listing, exchange, opportunity, support, contribution, extension, and status-legibility layer of the Nexus Ecosystem. It shall provide the structured public-good and controlled-access surface through which Nexus objects, capabilities, pathways, outputs, support needs, technical assets, learning opportunities, research opportunities, campaign opportunities, expertise pathways, Studio workflow candidates, Registry-recorded objects, Grid input candidates, TRL 1–10 evidence notes, Nexus Universe outputs, National Portfolio objects, and lawful handoff dependency packages may be made searchable, understandable, comparable within limits, supportable, reusable, correctable, and archivable.

1.1.2 Marketplace as Nexus system layer. Nexus Marketplace shall sit within the Nexus public-good stack as a discovery and routing layer, not as an authority layer. It shall connect Nexus Foundry, Nexus Acceleration, Nexus Universe, Nexus Network, Nexus Rails, Nexus Studio, Nexus Registry, Nexus Grid, Nexus Academy, Risk Academy, DICE, GRIx, DRI, Nexus Observatory, Nexus Campaigns, Nexus Labs, Risk Agency, iCRS, WILPs, micro-credentials, National Nodes, National Nexus Consortiums, National Working Groups, Nexus Competence Cells, National Consortium Companies, Project SPVs, sponsors, providers, hosts, public authorities, universities, communities, donors, insurers, capital readers, public finance readers, and lawful downstream actors through governed listing and routing rules.

1.1.3 Marketplace as governed discovery. Nexus Marketplace shall make bounded discovery possible by answering, for each listed object or opportunity:

1.1.3.1 what the object or opportunity is;

1.1.3.2 who stewards it;

1.1.3.3 which Nexus pathway produced, submitted, or routed it;

1.1.3.4 what class, release state, support class, and lifecycle state it carries;

1.1.3.5 what it may be used for;

1.1.3.6 what it may not be used for;

1.1.3.7 what public-safe status applies;

1.1.3.8 what data-use and AI-use labels apply;

1.1.3.9 what license, IP, contributor, support, and reuse conditions apply;

1.1.3.10 what provider-neutrality, sponsor-boundary, safeguard, public authority, finance, insurance, procurement, community, Indigenous protocol-sensitive, and no-execution boundaries apply;

1.1.3.11 what Registry, Studio, Grid, TRL, Nexus Universe, Foundry, Campaign, Academy, Labs, DICE, GRIx, DRI, Observatory, Risk Agency, or handoff records are linked;

1.1.3.12 what correction, withdrawal, retirement, supersession, recall, non-continuation, and archive pathways apply.

1.1.4 Marketplace as extension surface. Nexus Marketplace shall operate as the governed extension surface of Nexus by allowing eligible public-good assets, packs, connectors, APIs, schemas, dashboards, agents, workflows, templates, data objects, learning modules, quests, bounties, builds, campaigns, support packages, research opportunities, expertise pathways, Studio workflows, Registry records, Grid inputs, TRL evidence notes, and lawful handoff candidates to become discoverable without being converted into approval, endorsement, procurement eligibility, financeability, insurability, certification, public authority action, employment offer, community consent, deployment authorization, or execution authority.

1.1.5 Marketplace as status-legibility layer. Nexus Marketplace shall improve ecosystem usability by making status legible. It shall not hide uncertainty, unsupported status, lack of maintenance, data restrictions, AI-use limits, public-safe restrictions, sponsor influence, provider involvement, legal boundaries, safeguard concerns, correction history, or archive status. A Marketplace listing shall be useful because its limits are visible.

1.1.6 Marketplace as non-execution. Nexus Marketplace shall not itself execute projects, operate systems, contract implementation, procure goods or services, finance activities, underwrite risk, issue insurance, certify maturity, approve providers, issue public warnings, create public authority decisions, allocate public finance, create employment offers, grant community or Indigenous consent where applicable, authorize deployment, or command implementation. Its function is to list, classify, display, explain, route, support, correct, withdraw, retire, and archive within recorded Nexus boundaries.

***

### 1.2 Marketplace as Governed Discovery Infrastructure

1.2.1 Governed discovery doctrine. Nexus Marketplace shall be governed discovery infrastructure, not an uncontrolled catalogue. Listings shall be classified, scoped, labeled, stewarded, reviewed where required, linked to records where applicable, and bounded by no-conversion notices. The Marketplace shall preserve the difference between discoverability and authority.

1.2.2 Not a generic marketplace. Nexus Marketplace shall not be a generic commercial marketplace, consumer marketplace, app store, vendor catalogue, procurement portal, investment platform, securities platform, crowdfunding-securities portal, insurance marketplace, public finance platform, donor allocation platform, ratings platform, certification body, standards authority, employment marketplace, public authority platform, social ranking system, or execution environment by default.

1.2.3 Discovery before transaction. Nexus Marketplace shall default to discovery, learning, support routing, contribution routing, and lawful handoff preparation. It shall not default to transaction execution. Any payment, donation, sponsorship, subscription, support, bounty, service charge, licensing, enterprise handoff, procurement, investment, insurance, grant, public finance, or paid-work pathway shall require separate lawful terms, role classification, regulated-perimeter controls where applicable, and no-conversion notices.

1.2.4 Public-good discovery purpose. Nexus Marketplace shall support discovery of objects and opportunities that advance public-good resilience, DRR, DRF, DRI, public-good technology, digital public goods, open technical baselines, public-good software, observability, data commons, risk intelligence, public-safe reporting, national capability, learning, research, campaigns, Nexus Universe preparation, Nexus Foundry production, and lawful handoff dependency mapping.

1.2.5 Discovery surfaces. Nexus Marketplace may provide public, controlled, restricted, institutional, national, regional, global, thematic, Studio-linked, Registry-linked, Campaign-linked, Foundry-linked, Academy-linked, Labs-linked, Risk Agency-linked, DICE-linked, Observatory-linked, Nexus Universe-linked, and handoff-linked discovery surfaces. Each surface shall display only what is appropriate to its access class, public-safe status, data-use rules, AI-use rules, safeguard status, and legal boundaries.

1.2.6 Marketplace filtering and search. Marketplace may support search, filters, categories, tags, ontology mapping, controlled vocabulary, recommendations, collection pages, national pages, thematic pages, Foundry collections, Campaign collections, Academy collections, Labs collections, DICE collections, DRI collections, Studio collections, Registry collections, Nexus Universe collections, support collections, and handoff collections. Search and filtering shall not be represented as ranking, endorsement, certification, procurement scoring, finance scoring, insurance scoring, public authority classification, or quality approval.

1.2.7 Comparability within limits. Marketplace may allow users to compare listed objects by class, scope, support class, release class, steward, license, public-safe status, data-use label, AI-use label, Registry status, Studio status, Grid input status, TRL evidence note, correction history, localization status, and support availability. Comparison shall not imply ratings, rankings, procurement recommendations, provider superiority, financeability, insurability, certification, or official approval.

1.2.8 Governed discovery boundary. Discovery through Nexus Marketplace shall create awareness and routing only. It shall not create recognition, endorsement, approval, public authority action, procurement status, supplier approval, financeability, insurability, underwriting acceptance, donor commitment, public finance allocation, certification, rating, employment offer, community consent, Indigenous consent where applicable, deployment authorization, operational command, or execution authority.

1.4.1 Public-good legibility doctrine. Nexus Marketplace shall make public-good work legible to users, contributors, countries, communities, public authorities in learning roles, universities, labs, sponsors, providers, donors, insurers, capital readers, public finance readers, developers, Campaign teams, Foundry builders, Nexus Universe participants, and lawful downstream actors. It shall show what exists, what is missing, what is supported, what is experimental, what is public-safe, what is restricted, what is maintained, what is deprecated, what is corrected, what is withdrawn, and what is archived.

1.4.2 Legibility through record cards. Each material listing should display a Marketplace Record Card or equivalent status profile identifying class, steward, source, intended use, prohibited use, release class, support class, lifecycle state, data-use label, AI-use label, public-safe status, safeguard status, sponsor/provider status, Registry linkage, Studio linkage, Grid / TRL status where applicable, Nexus Universe linkage where applicable, correction history, and no-conversion notices.

1.4.3 Legibility through status truth. Marketplace shall not display objects as current when they are archived, supported when unsupported, public-safe when unreviewed, open when restricted, deployable when only experimental, maintained when deprecated, approved when merely listed, or handoff-ready when only a dependency candidate. Status truth shall be more important than promotional clarity.

1.4.4 Legibility for public authorities. Marketplace may help public authorities in learning roles discover public-good assets, dashboards, DRI templates, public-safe summaries, Studio workflows, training modules, National Portfolio objects, Nexus Universe outputs, and handoff dependency packages. Such legibility shall not create public authority approval, procurement action, regulatory comfort, public warning, official classification, public finance decision, or policy adoption.

1.4.5 Legibility for capital, insurance, donor, and public finance readers. Marketplace may help capital readers, insurers, reinsurers, donors, development actors, and public finance readers discover readiness questions, assumptions registers, dependency registers, diligence-gap templates, DRF readiness notes, DRI objects, public-good support needs, public-safe summaries, and handoff dependency packages. Such legibility shall be no-reliance, non-soliciting, non-transactional, and regulated-perimeter controlled.

1.4.6 Legibility for communities. Marketplace may make community-facing, public-interest, accessibility, translation, safeguard, local resilience, youth, humanitarian, and protected-knowledge-sensitive resources discoverable. Such legibility shall not expose sensitive information, create representation claims, imply community consent, imply Indigenous consent where applicable, or turn community participation into public approval.

1.4.7 Legibility for builders. Marketplace may help Foundry builders, developers, Working Groups, Competence Cells, Labs, and contributors discover tasks, quests, bounties, builds, templates, schemas, datasets, APIs, connectors, dashboards, Studio workflows, learning modules, support needs, and maintainer pathways. Such legibility shall not create employment, contractor work, admissions, procurement work, expert standing, or execution assignment unless separately and lawfully recorded.

1.4.8 Legibility boundary. Public-good legibility shall make the ecosystem understandable. It shall not make listed objects authoritative by visibility, legitimate by polish, validated by popularity, financeable by interest, insurable by risk display, procurable by comparison, certified by badge, approved by Registry linkage, deployable by Studio readiness, or executable by handoff candidacy.

2.1.1 Classification as the first control. Every Nexus Marketplace listing shall be classified before publication, display, search indexing, support enablement, Studio routing, Registry linkage display, Grid or TRL display, Nexus Universe featuring, or handoff discovery. Classification shall identify what the listed object is, what it is not, what pathway produced or submitted it, what status it carries, what use is permitted, what use is prohibited, what review has occurred, what support exists, what public-safe limits apply, what data and AI-use rules apply, what safeguards apply, and what no-conversion notices must be displayed.

2.1.2 Object class determines meaning. A listing’s object class shall determine its record requirements, status labels, support class, release class, review gates, public display rules, data-use labels, AI-use labels, IP and licensing terms, sponsor and provider boundary language, public authority boundary language, finance and insurance boundary language, procurement boundary language, consent boundary language, Nexus pathway routing, correction pathway, and archive treatment.

2.1.3 No class collapse. Nexus Marketplace shall not collapse distinct object classes into vague “solutions,” “products,” “projects,” “opportunities,” or “partners” where such labels obscure meaning. A public-good software object is not a certified product. A Studio workflow is not decision authority. A Registry entry is not universal approval. A Grid input is not maturity certification. A TRL evidence note is not deployment authorization. A provider contribution is not provider validation. A support listing is not funding approval. A handoff package is not implementation authority. A campaign opportunity is not public mandate. A learning pathway is not professional licensure. A Risk Agency pathway is not automatic expert standing.

Composite listings shall identify each component, component status, component steward, component license, component data-use label, component AI-use label, component support class, component correction pathway, and component archive state.

2.1.6 Class inheritance. Where a listing contains components with different restrictions, the most restrictive applicable rule shall control unless a component-level exception is clearly recorded. A public package shall not make restricted data public; a public-safe summary shall not make protected knowledge open; a Studio-ready workflow shall not make a dataset AI-usable; a Marketplace listing shall not make a provider approved; and a handoff candidate shall not make execution authorized.

2.1.7 Controlled vocabulary. Marketplace object classes shall use controlled vocabulary aligned with Nexus Foundry, Nexus Acceleration, Nexus Registry, Nexus Studio, Nexus Grid, TRL 1–10, Nexus Network, Nexus Rails, DICE, GRIx, DRI, Nexus Observatory, Nexus Campaigns, Nexus Academy, Risk Academy, Nexus Labs, Risk Agency, iCRS, National Nodes, Working Groups, Competence Cells, Nexus Universe, National Consortium Companies, Project SPVs, and lawful handoff records.

Ambiguity shall be corrected before material reliance occurs.

Volunteer listings shall not imply employment, wages, benefits, contractor status, internship status, professional engagement, public authority role, emergency response role, procurement role, finance role, insurance role, or execution responsibility unless separately and lawfully established.

6.4.4 WILP not hidden labor. WILPs and micro-credentials listed in Marketplace shall not be used to disguise unpaid labor, contractor work, professional services, operational services, procurement work, public authority work, or implementation work where law or fairness requires another arrangement. WILP work shall be supervised, learning-linked, bounded, and protected.

Provider listings, provider pages, service-support listings, tools, software, APIs, dashboards, equipment, cloud, compute, data services, integration support, Studio workflows, Nexus Universe demonstrations, public-good software, support classes, reviews, badges, Registry entries, Grid inputs, or TRL evidence notes shall not create supplier approval, vendor preference, procurement eligibility, tender advantage, procurement scoring, procurement recommendation, or contract award.

6.5.4 Public authority procurement boundary. Public authorities may use Marketplace for learning and discovery only unless a separate lawful procurement process applies. Browsing, saving, requesting information, attending a Studio demonstration, viewing provider listings, joining a public authority learning workflow, or accessing a handoff package shall not start or satisfy procurement.

6.5.10 Procurement boundary. Marketplace listing, discovery, comparison, review, support class, Registry linkage, Studio demonstration, Grid input, TRL evidence, Nexus Universe visibility, or handoff candidacy shall not create procurement, supplier approval, vendor preference, contract award, public authority purchasing status, or procurement recommendation by implication.

Finance, investment, donor, public finance, or insurance overclaims shall be corrected through listing revision, public-safe notice, readiness-room correction, support suspension, Marketplace delisting, Registry correction, Studio correction, Grid / TRL correction, Nexus Universe correction, handoff recall, or archive.

### 6.15 Final Part VI Statement

6.15.1 Final transaction-boundary formula. Nexus Marketplace shall enable discovery, support, participation, contribution, learning, research, Studio routing, Registry status display, Grid / TRL visibility, Nexus Universe continuity, and lawful handoff awareness without becoming a transaction platform by default. Where payment, support, sponsorship, bounty, service, subscription, enterprise support, or handoff pathways are enabled, they shall be governed by separate terms, support ledgers, fiscal stewardship, regulated-perimeter controls where required, public-safe notices, correction, and archive.

6.15.2 Final support discipline. Public-good support shall not become investment. Sponsorship shall not become control. Provider support shall not become validation. Donations shall not become public authority approval. Bounties shall not become employment. WILPs shall not become hidden labor. Service listings shall not become procurement. Readiness notes shall not become financeability. Insurance-readiness shall not become insurance approval. Public finance relevance shall not become allocation. Handoff discovery shall not become execution.

6.15.3 Final declaration. Nexus Marketplace shall be powerful because it can mobilize support, opportunity, contribution, service discovery, public-good resources, and lawful downstream awareness at scale; it shall be trustworthy because every transaction-sensitive surface is bounded. The Marketplace shall let users support what matters, contribute where useful, learn where appropriate, request help where lawful, and discover handoff context where relevant, while preventing every support, opportunity, payment, sponsorship, provider listing, service listing, readiness note, or handoff candidate from becoming false procurement, finance, insurance, certification, employment, public authority approval, consent, deployment, command, or execution by implication.

### 8.12 Final Part VIII Statement

8.12.1 Final governance formula. Nexus Marketplace shall be governed through stewardship, listing gates, quality review, trust and safety, ratings discipline, metrics discipline, incident response, stop-the-line authority, correction, delisting, suspension, withdrawal, deprecation, retirement, recall, archive, registers, renewal, and continuous improvement. Governance shall preserve discovery at scale without allowing discovery to become authority.

8.12.2 Final trust formula. Marketplace trust shall come from record truth, not promotional confidence; from visible limits, not hidden disclaimers; from correction, not defensiveness; from role separation, not convenience; from support transparency, not sponsorship influence; from provider neutrality, not vendor polish; from public-safe publication, not viral visibility; from data and AI labels, not uncontrolled reuse; from national routing, not bypass; from handoff discipline, not execution overclaim.

8.12.3 Final declaration. Nexus Marketplace shall be safe to scale because every listing passes through gates, every powerful object carries labels, every support pathway has terms, every provider contribution has neutrality, every sponsor contribution has boundaries, every public authority reference is controlled, every data object has use limits, every AI object has processing limits, every Studio workflow has non-decision limits, every Grid or TRL display has no-certification limits, every handoff candidate has recipient-responsibility limits, every incident has containment, every correction has memory, and every archive prevents stale status from becoming false authority.

9.3.14 Nexus Universe-Linked. A listing in Nexus Universe-Linked state is associated with a Nexus Universe cycle, arena, room, Core Build request, Core Build output, public-safe report, Studio demonstration, readiness room, or after-action record. Nexus Universe linkage shall not imply endorsement or approval.

9.3.15 Handoff-Candidate. A listing in Handoff-Candidate state may be relevant to a lawful handoff dependency package. Handoff-Candidate state shall not create implementation authorization or downstream reliance.

9.3.16 Corrected. A listing in Corrected state has been amended to address error, overclaim, stale status, data issue, AI-use issue, security issue, provider issue, sponsor issue, public-safe issue, or handoff issue. Correction history shall be preserved where relevant.

9.3.17 Suspended. A listing in Suspended state is temporarily unavailable or restricted pending review, correction, incident handling, rights clarification, support clarification, security review, or boundary review.

9.3.18 Withdrawn. A listing in Withdrawn state is no longer active or discoverable for ordinary use because continued display or use is inappropriate, unsafe, unsupported, unlawful, misleading, or superseded.

9.3.19 Deprecated. A listing in Deprecated state remains visible for transition, compatibility, documentation, or historical reference but is no longer preferred for current use.

### 9.5 Handoff Dependency Listings

9.5.1 Handoff listing doctrine. Nexus Marketplace may make lawful handoff dependency packages discoverable only where the listing clearly states that the package provides context, dependencies, evidence references, data references, public-safe summaries, readiness questions, and recipient responsibility information, and does not authorize implementation, procurement, finance, insurance, public authority action, deployment, or execution.

9.5.2 Handoff Dependency Package defined. A Handoff Dependency Package is a bounded package of records and contextual materials that may assist a competent downstream actor in conducting independent diligence, planning, public authority engagement, procurement preparation, finance or insurance inquiry, technical review, safeguard review, data review, or lawful implementation preparation without Nexus executing or approving the downstream action.

9.5.3 Handoff listing requirements. Each Handoff Dependency Listing shall identify package name, source pathway, steward, object class, recipient class, evidence context, data context, technical context, public-safe status, safeguard status, data-use labels, AI-use labels, IP and license terms, public authority dependencies, legal dependencies, finance and insurance questions, procurement boundaries, provider-neutrality notes, sponsor influence notes, recipient responsibilities, no-reliance statement, correction pathway, recall pathway, access class, and archive status.

9.5.4 Recipient classes. Handoff recipients may include National Consortium Companies, Project SPVs, public authorities, providers, operators, contractors, funders, insurers, donors, public finance readers, universities, labs, community actors where appropriate, or other competent lawful actors. Recipient class shall be recorded and shall not be presumed.

9.5.5 Recipient responsibility statement. Each Handoff Dependency Listing shall state that recipients remain responsible for independent diligence, legal compliance, public authority approvals, procurement, finance, insurance, engineering, safety, cybersecurity, data protection, privacy, AI-use compliance, community engagement, Indigenous protocols where applicable, environmental and social safeguards, deployment, operations, maintenance, and execution.

9.5.6 Public authority dependencies. Handoff listings involving public authorities shall identify public authority dependencies without implying approval, endorsement, permit, license, official classification, public warning, public finance allocation, regulatory comfort, or public authority decision.

9.5.7 Finance and insurance questions. Handoff listings may include finance-readiness, insurance-readiness, donor-readiness, public finance relevance, assumptions, dependencies, risk-layering questions, diligence gaps, and no-reliance materials. Such materials shall not create financeability, insurability, underwriting acceptance, investment readiness, donor commitment, public finance allocation, valuation, rating, solicitation, offer, or transaction readiness.

9.5.8 Provider-neutrality and sponsor notes. Handoff listings shall disclose provider contributions, sponsor support, conflicts, dependencies, alternatives where appropriate, and limits of any provider or sponsor involvement. Provider involvement shall not validate providers; sponsor support shall not control handoff.

9.5.9 Handoff access controls. Handoff listings may be public-safe, controlled, restricted, secure-room-only, data-room-only, recipient-only, national-pathway-required, public-authority-learning-only, or archive-only. Access shall be governed by data-use labels, AI-use labels, privacy, cybersecurity, protected knowledge, public authority restrictions, community safeguards, and legal terms.

9.5.10 Handoff correction and recall. Handoff listings and packages shall be corrected, restricted, recalled, superseded, withdrawn, or archived where evidence changes, data rights change, public-safe status changes, safeguard status changes, provider-neutrality issues arise, sponsor influence appears, public authority dependency changes, legal dependency changes, Grid / TRL status changes, downstream misuse occurs, or overclaim appears.

9.5.11 Handoff boundary. Handoff Dependency Listings shall transfer context, not authority. They shall not authorize implementation, approve procurement, validate providers, approve finance, approve insurance, create public authority approval, transfer community consent, transfer Indigenous consent where applicable, transfer data rights beyond recorded terms, deploy systems, operate projects, or execute work.

***

### 9.6 Archive

9.6.1 Archive doctrine. Nexus Marketplace archive shall preserve institutional memory while preventing stale, unsupported, withdrawn, superseded, deprecated, retired, recalled, or non-continuing listings from being mistaken for current status. Archive shall make the past visible where useful without allowing past visibility to become present authority.

9.6.2 Archive objects. Marketplace archive may include retired listings, withdrawn listings, deprecated public-good assets, superseded Foundry outputs, closed Campaign opportunities, completed support listings, expired WILPs, retired micro-credentials, old Labs calls, retired Risk Agency pathways, sealed DICE objects, corrected GRIx mappings, withdrawn DRI dashboards, archived Observatory packs, closed Studio workflows, superseded Registry links, old Grid inputs, old TRL evidence notes, prior Nexus Universe outputs, recalled handoff packages, support ledgers, correction records, and incident records.

9.6.3 Archive status fields. Each archived listing shall identify final status, reason for archive, prior lifecycle state, correction history, support history, data-use status, AI-use status, public-safe status, security status, IP and license status, Registry status, Studio status, Grid / TRL status, Nexus Universe status, handoff status, successor records, recall status, access class, and current-use limits.

9.6.4 Archive access classes. Archive records may be public, controlled, restricted, sealed, steward-only, legal-hold, public authority-sensitive, protected knowledge-sensitive, Indigenous protocol-sensitive where applicable, youth-sensitive, secure-room-only, data-room-only, handoff-recipient-only, or deletion-verified depending on applicable rules.

9.6.5 Archive-not-current notice. Archived listings shall carry Archive-Not-Current notices and shall not be displayed as active, supported, maintained, open, public-safe released, Studio-ready, Registry-current, Grid-current, TRL-current, Nexus Universe-current, support-enabled, handoff-current, or implementation-relevant unless reinstated by current record.

9.6.6 Successor records. Archive shall link to successor records where available, including newer versions, corrected versions, national localized versions, replacement listings, current Registry entries, new Studio workflows, updated Grid / TRL records, new Nexus Universe cycle outputs, or revised handoff packages.

9.6.7 Archive and search. Marketplace search may include archived results only where archive results are clearly labeled and separated from current results. Archived results shall not be promoted into current discovery, featured placement, support pathways, opportunity pathways, or handoff pathways unless reinstated.

9.6.8 Archive and correction. Archived records may still be corrected where archive contents are wrong, public-safe meaning is unsafe, personal data is exposed, protected knowledge is exposed, public authority language is misleading, provider or sponsor claims are wrong, or handoff recall requires update.

9.6.9 Archive retention and deletion. Archive retention shall be governed by legal requirements, institutional memory, privacy rights, support ledgers, incident records, correction needs, public-safe needs, and deletion or sealing rules. Deletion may occur where required, and deletion verification may be recorded where appropriate.

9.6.10 Archive boundary. Marketplace archive preserves memory, accountability, and learning. It shall not create current approval, current support, current certification, procurement status, financeability, insurance approval, public authority action, consent, deployment authorization, operational command, or execution.

***

### 9.7 Renewal, Expiry, Reinstatement, and Non-Continuation

9.7.1 Renewal doctrine. Marketplace listings shall not continue indefinitely where current meaning matters. Renewal may be required for listings whose status depends on current support, current technology, current law, current data rights, current AI-use permissions, current security posture, current public-safe language, current sponsor or provider status, current public authority context, current Nexus Universe cycle, current Grid or TRL status, or current handoff relevance.

9.7.2 Expiry. Marketplace listings, support listings, opportunity listings, WILPs, micro-credentials, Studio workflows, public-safe summaries, provider listings, sponsor listings, host listings, data labels, AI-use labels, Grid / TRL displays, Nexus Universe features, and handoff candidates may expire according to recorded rules.

9.7.3 Renewal requirements. Renewal may require steward confirmation, support confirmation, public-safe review, data-use review, AI-use review, cybersecurity review, IP and license review, sponsor/provider review, public authority boundary review, procurement boundary review, finance and insurance boundary review, safeguard review, localization review, Registry confirmation, Studio confirmation, Grid / TRL update, Nexus Universe cycle update, handoff confirmation, or archive.

9.7.4 Renewal records. Renewal shall generate a record identifying what was renewed, what was reviewed, what changed, what stayed the same, what limitations apply, what notices were updated, and when the next renewal is due.

9.7.5 Reinstatement. A suspended, withdrawn, deprecated, retired, recalled, archived, or non-continuing listing may be reinstated only through recorded review, updated status, corrected labels, current support, current rights, current public-safe review, current data-use and AI-use labels, and applicable gates. Reinstatement shall not erase prior status history.

9.7.6 Non-continuation. Non-continuation shall be a valid Marketplace outcome where a listing should not proceed, renew, or be reinstated. Non-continuation may reflect insufficient evidence, unresolved safeguards, data-rights limits, AI-use limits, cybersecurity issues, public-safe risk, support lapse, provider/sponsor conflict, public authority boundary risk, finance or procurement boundary risk, community concern, Indigenous protocol-sensitive concern where applicable, technical infeasibility, strategic change, or lawful impossibility.

9.7.7 Expired status display. Expired listings shall not be displayed as current. They may be marked expired, renewal-required, archive-only, or non-continuing according to record.

9.7.8 Renewal without automatic authority. Renewal of a listing shall mean only that the Marketplace listing has been updated for continued discovery within scope. Renewal shall not create certification, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution.

9.7.9 Non-continuation communication. Where non-continuation affects users, support, Nexus Universe outputs, Campaigns, Studio workflows, Registry status, Grid / TRL display, or handoff packages, Marketplace shall issue appropriate notices, support updates, correction records, successor links, recall notices, or archive labels.

9.7.10 Renewal and non-continuation boundary. Renewal, expiry, reinstatement, and non-continuation manage current status. They shall not create approval, certification, procurement, finance, insurance, public authority action, consent, deployment, or execution.

***

### 9.8 Cross-System Record Synchronization

9.8.1 Synchronization doctrine. Marketplace records shall synchronize with connected Nexus systems where status truth, listing meaning, access, support, data-use, AI-use, public-safe status, safeguard status, security status, Registry status, Studio status, Grid / TRL display, Nexus Universe status, Campaign status, Foundry status, DICE status, GRIx status, DRI status, Observatory status, Academy status, Labs status, Risk Agency pathway status, or handoff status changes.

9.8.2 Synchronization sources. Synchronization may be triggered by Nexus Foundry corrections, Acceleration updates, Campaign updates, Academy updates, WILP expiries, micro-credential updates, Labs restrictions, Risk Agency pathway changes, DICE data-use changes, GRIx mapping updates, DRI dashboard corrections, Observatory updates, Studio workflow shutdowns, Registry status changes, Grid input withdrawals, TRL downgrades, Nexus Universe after-action records, National Node updates, Working Group updates, Competence Cell updates, support ledger updates, provider updates, sponsor updates, or handoff recalls.

9.8.3 Synchronization targets. Marketplace synchronization may update Record Cards, listing pages, search indexing, badges, support links, downloads, APIs, widgets, collections, bundles, catalogues, portfolios, provider pages, sponsor pages, Campaign pages, Academy pages, Labs pages, Studio routing, Registry display, Grid / TRL display, Nexus Universe pages, handoff packages, correction notices, and archive records.

9.8.4 Dependency graph. Marketplace shall maintain or reference dependency relationships where a listing depends on datasets, APIs, software, dashboards, models, Studio workflows, Registry entries, Grid inputs, TRL evidence notes, public-safe summaries, support records, provider contributions, sponsor support, Nexus Universe outputs, or handoff packages.

9.8.5 Dependency correction. Where a dependency is corrected, withdrawn, deprecated, retired, recalled, or archived, Marketplace shall assess affected listings and update or restrict them where appropriate. A bundle, collection, Studio workflow, or handoff package shall not remain current if a critical dependency is no longer current unless the limitation is clearly recorded.

9.8.6 Status conflict rule. Where records conflict, the more restrictive, more current, or more authoritative internal status within the relevant Nexus pathway shall control until reconciliation. Marketplace shall not preserve a more permissive display where a connected system has imposed correction, withdrawal, suspension, recall, or archive.

9.8.7 Synchronization delays. Where synchronization is delayed, Marketplace may display interim notices such as Status Under Review, Linked Record Updating, Support Status Pending, Registry Status Pending, Studio Status Pending, Grid / TRL Status Pending, Handoff Status Pending, or Public-Safe Review Pending.

9.8.8 Synchronization record. Material synchronization actions shall generate records identifying source change, affected listings, changes applied, notifications issued, downstream dependencies, unresolved conflicts, and archive.

9.8.9 Synchronization boundary. Cross-system synchronization preserves status truth. It shall not create approval, certification, procurement status, financeability, insurance approval, public authority action, consent, deployment authorization, or execution.

***

### 9.9 Marketplace Handoff to Legal, Technical, Support, and Enterprise Processes

9.9.1 Process-handoff doctrine. Marketplace may route a listing, support pathway, opportunity, data object, Studio workflow, Registry-linked object, Grid / TRL display, Nexus Universe output, or handoff dependency package to additional legal, technical, support, enterprise, public authority, procurement, finance, insurance, or operational processes only through recorded handoff, no-reliance language, recipient responsibility, and role separation.

9.9.2 Legal process handoff. Marketplace may route issues to legal review, privacy review, data protection review, IP review, sanctions review, export-control review, anti-bribery review, tax review, employment review, charitable solicitation review, procurement-boundary review, public authority boundary review, or regulated-perimeter review. Such routing shall not create legal advice to users or legal approval by Marketplace.

9.9.3 Technical process handoff. Marketplace may route objects to Foundry, Studio, security review, vulnerability review, data review, AI-use review, Grid review, TRL review, Observatory review, DRI review, GRIx review, DICE stewardship, or technical support. Such routing shall not create technical approval or deployment authorization.

9.9.4 Support process handoff. Marketplace may route support needs to support stewards, fiscal stewards, sponsors, donors, providers, hosts, Academy support, Campaign support, Nexus Universe support, translation support, accessibility support, or public-good maintenance support. Such routing shall not create funding, donor commitment, sponsor control, or provider validation.

9.9.5 Enterprise process handoff. Marketplace may route handoff dependency packages to National Consortium Companies, Project SPVs, providers, operators, contractors, funders, insurers, donors, public finance readers, or lawful downstream actors. Such routing shall not create procurement, finance, insurance, public authority approval, or execution by Nexus.

9.9.6 Public authority process handoff. Marketplace may route public authority-relevant materials to public authority learning or competent public authority channels where appropriate. Such routing shall not create official approval, policy adoption, procurement action, public finance allocation, warning, emergency command, or public authority decision.

9.9.7 Recipient acknowledgement. Where handoff creates reliance risk, Marketplace may require recipient acknowledgement of no-reliance, recipient responsibility, data-use obligations, AI-use obligations, confidentiality, public-safe restrictions, provider-neutrality notes, sponsor-boundary notes, correction obligations, and recall obligations.

9.9.8 Handoff tracking. Marketplace may track handoff routing, recipient class, access date, package version, correction notices, recall notices, and archive status where appropriate for accountability and recall.

9.9.9 Handoff boundary. Marketplace handoff to any legal, technical, support, enterprise, public authority, procurement, finance, insurance, or operational process shall route context only. It shall not create approval, certification, procurement status, financeability, insurance approval, public authority action, consent, deployment authorization, operational command, or execution authority.

***

### 9.10 Final Part IX Statement

9.10.1 Final instrument formula. Nexus Marketplace shall operate through legal instruments, registers, records, lifecycle states, handoff terms, archive rules, renewal rules, synchronization rules, and process-handoff discipline. Every listing shall be governed by terms; every term shall be connected to records; every record shall be classified; every classification shall carry labels; every label shall carry limits; every support pathway shall carry terms; every handoff shall carry recipient responsibility; every correction shall carry memory; every archive shall carry non-current status.

9.10.2 Final lifecycle discipline. A Marketplace listing shall never be treated as a static page. It shall be a governed record that may move from draft to submitted, classified, under review, listed, restricted, supported, maintained, localized, Studio-ready, Registry-linked, Grid / TRL-linked, Nexus Universe-linked, handoff-candidate, corrected, suspended, withdrawn, deprecated, retired, recalled, archived, or non-continuing. The lifecycle shall protect users from stale authority and protect Nexus from status drift.

9.10.3 Final handoff discipline. Handoff through Marketplace shall be context transfer, not authority transfer. Handoff dependency packages may help competent actors understand evidence, data, safeguards, readiness questions, dependencies, provider-neutrality notes, sponsor influence notes, and recipient responsibilities. They shall never be implementation approvals, procurement approvals, finance approvals, insurance approvals, public authority approvals, consent transfers, data-right transfers, deployment authorizations, operational commands, or execution by Nexus.

9.10.4 Final declaration. Nexus Marketplace shall be institutionally reliable because it is not merely a surface for listings. It shall be an instrumented record system in which terms govern action, registers preserve status, records carry meaning, lifecycle states prevent drift, synchronization protects current truth, archive preserves memory, and handoff remains bounded. This legal and records architecture shall allow the Marketplace to scale discovery, support, contribution, learning, research, Studio routing, Registry status, Grid / TRL visibility, Nexus Universe continuity, and lawful handoff awareness while preventing every listing, record, support action, status label, or handoff package from becoming false approval, procurement, finance, insurance, certification, public authority action, consent, deployment, command, or execution.

## 10. Standard No-Conversion Rule and Final Nexus Marketplace Operating Formula

### 10.1 No Recognition by Discoverability

10.1.1 No-recognition doctrine. No Nexus Marketplace listing, Marketplace Record Card, collection, bundle, catalogue, portfolio, public-good asset, Foundry output, Campaign opportunity, Academy pathway, WILP, micro-credential, Labs opportunity, Risk Agency pathway, DICE object, GRIx mapping, DRI object, Observatory pack, Studio workflow, Registry-linked object, Grid input, TRL 1–10 evidence note, Nexus Universe output, National Portfolio object, provider listing, sponsor listing, host listing, support listing, service-support listing, opportunity listing, handoff dependency listing, badge, review, rating, metric, download count, feature placement, public display, or archive record shall create recognition by implication.

10.1.2 Discoverability is not recognition. Discoverability shall mean only that a listing has been made visible, searchable, accessible, or routable within its recorded access class, status, labels, terms, restrictions, and lifecycle state. Discoverability shall not mean that Nexus, The Global Centre for Risk and Innovation (GCRI), The Global Risks Forum (GRF), The Global Risks Alliance (GRA), a protocol authority, a National Node, a National Nexus Consortium, a National Working Group, a Nexus Competence Cell, Nexus Universe, Nexus Foundry, Nexus Registry, Nexus Studio, Nexus Grid, a public authority, a sponsor, a provider, a donor, an insurer, a capital reader, a public finance reader, a university, a community, or any other participant recognizes, endorses, approves, validates, certifies, recommends, adopts, or authorizes the listed object.

10.1.3 Listing status is not recognition. Listed, featured, public-safe reviewed, Registry-linked, Studio-ready, Grid-input candidate, TRL-evidence candidate, Nexus Universe candidate, support-enabled, maintained, provider-supported, sponsor-supported, National-Node-supported, handoff-candidate, or archived status shall not be represented as recognition unless a separate lawful and recorded recognition instrument expressly creates a bounded recognition status.

10.1.4 Public-good status is not recognition. A listing may be public-good-oriented, open, reusable, supportable, public-safe, Academy-linked, Foundry-produced, Campaign-linked, Nexus Universe-linked, or National Portfolio-linked without being recognized as correct, authoritative, mature, safe, complete, deployable, financeable, insurable, procurable, endorsed, certified, or approved.

10.1.5 Featured status is not recognition. Featured placement, curated collections, promoted campaigns, Nexus Universe collections, National Portfolio pages, thematic catalogues, public-good bundles, Studio collections, or handoff collections shall not imply superior quality, endorsement, priority, official selection, procurement relevance, financeability, insurability, public authority approval, certification, or implementation priority.

10.1.6 User activity is not recognition. Views, downloads, saves, follows, forks, reuse requests, support requests, ratings, reviews, comments, shares, sign-ups, access requests, volunteer applications, learning enrollments, support pledges, donations, sponsorship interest, Studio requests, or handoff package views shall not imply recognition, validation, approval, procurement interest, finance interest, insurance interest, public authority interest, or implementation commitment.

10.1.7 Institution presence is not recognition. Participation, viewing, attendance, contribution, support, review, listing, sponsorship, provider contribution, public authority learning, Nexus Universe participation, Studio participation, Academy participation, Campaign participation, Labs participation, or Risk Agency pathway presence by an institution shall not imply that institution recognizes or endorses the listed object, the Marketplace, the campaign, the provider, the sponsor, the steward, the national pathway, or any downstream action.

10.1.8 Recognition language control. Marketplace materials shall not use “recognized,” “approved,” “endorsed,” “certified,” “accredited,” “official,” “validated,” “preferred,” “recommended,” “authorized,” “adopted,” “accepted,” “government-ready,” “public authority-approved,” “Nexus-ready,” “finance-ready,” “insurance-ready,” “procurement-ready,” or similar language unless separately and lawfully true within a recorded scope and displayed with appropriate limits.

10.1.9 Recognition overclaim correction. Recognition overclaims shall be corrected through listing revision, badge removal, Record Card correction, public-safe notice, provider correction, sponsor correction, Registry display correction, Studio label correction, Grid / TRL display correction, Nexus Universe material correction, support listing correction, handoff recall, delisting, withdrawal, or archive.

***

### 10.2 No Procurement by Listing

10.2.1 No-procurement doctrine. Nexus Marketplace shall preserve procurement neutrality. No Marketplace listing, provider page, provider contribution, service-support listing, support class, review, badge, rating, comparison, Studio workflow, Nexus Universe demonstration, Registry linkage, Grid input, TRL evidence note, public-good asset, Foundry output, handoff candidate, user feedback, or public authority interaction shall create procurement status by implication.

10.2.2 Listing is not supplier approval. A provider, tool, software, service, API, dashboard, dataset, model, equipment, cloud resource, compute resource, integration pathway, training pathway, maintenance pathway, Studio workflow, or public-good software object shall not become supplier-approved, vendor-approved, procurement-eligible, preferred, shortlisted, tender-ready, purchasing-ready, or contract-ready merely by being listed in Marketplace.

10.2.3 Marketplace is not a procurement portal. Nexus Marketplace shall not be treated as a public procurement portal, purchasing catalogue, supplier prequalification system, tender platform, bid evaluation tool, approved vendor list, framework agreement, vendor ranking engine, public authority buying channel, or procurement recommendation system by default.

10.2.4 Comparison is not procurement evaluation. Search filters, comparison views, status labels, support classes, documentation completeness, downloads, reviews, ratings, usage signals, provider pages, Studio demonstrations, Grid inputs, TRL evidence notes, or Nexus Universe displays shall not be used or represented as procurement scoring, supplier vetting, product evaluation, public authority recommendation, or contract award basis by implication.

10.2.5 Public authority discovery is not procurement. Public authority browsing, saving, following, requesting information, attending a Studio demonstration, viewing Marketplace comparisons, participating in public authority learning rooms, viewing provider listings, accessing public-safe materials, or reviewing handoff dependency packages shall not commence, satisfy, substitute for, or evidence a procurement process.

10.2.6 Provider claims discipline. Providers shall not use Marketplace listing, public-good support, Nexus Universe visibility, Studio demonstration, Registry linkage, Grid or TRL display, public-safe review, support class, reviews, ratings, or user activity to claim approved supplier status, preferred provider status, government-ready status, procurement readiness, public authority approval, public purchasing interest, or competitive advantage.

10.2.7 Sponsor procurement neutrality. Sponsor support shall not influence Marketplace ranking, provider visibility, public authority-facing materials, Studio access, Grid / TRL display, Nexus Universe routing, handoff candidacy, provider comparison, or public-safe summaries in a manner that creates procurement distortion.

10.2.8 Enterprise support separation. Enterprise-support listings, implementation-support listings, service-support listings, maintenance-support listings, integration-support listings, or downstream provider support pathways shall be separated from procurement decisions. Users and downstream actors remain responsible for their own procurement processes, conflicts, competition rules, public authority approvals, legal review, technical diligence, and contracting.

10.2.9 Procurement-sensitive notices. Listings with possible procurement interpretation shall display no-procurement notices, provider-neutrality notes, review limits, support-class limits, public authority boundary language, and no-reliance statements where appropriate.

10.2.10 Procurement overclaim correction. Procurement overclaims shall trigger listing correction, provider page correction, public-safe notice, support listing correction, Marketplace delisting, Studio label correction, Registry correction, Grid / TRL display correction, Nexus Universe material correction, handoff recall, provider restriction, sponsor restriction, or archive.

Marketplace may use lawful sustainability models, including institutional subscriptions, listing support fees where appropriate, platform support, training support, controlled support, enterprise support without validation, sponsorship without control, payment processing pass-throughs, Nexus Universe packages, and public-good support, provided such models do not create pay-to-recognition, pay-to-validation, pay-to-procurement, pay-to-finance, pay-to-routing, pay-to-handoff, or pay-to-public-authority attention.

10.9.8 Capture correction. Suspected Marketplace capture shall trigger review, disclosure, recusal, support restriction, sponsor/provider correction, ranking correction, feature placement correction, listing correction, public-safe notice, governance correction, stop-the-line, withdrawal, non-continuation, or archive.

It shall be powerful because it lets the world find, support, contribute to, learn from, reuse, localize, correct, and route Nexus work. It shall be legitimate because it refuses to let listing, visibility, polish, popularity, payment, sponsorship, provider contribution, public authority attention, Nexus Universe presence, Registry linkage, Studio readiness, Grid input, TRL evidence, support, or handoff candidacy become false recognition, procurement, finance, insurance, certification, public authority approval, consent, deployment, command, or execution.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.therisk.global/organization/operations/pillars/v.-marketplace.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
