# XXVI. SECURITY

Security defines how Nexus protects records, systems, access, and workflows through zero-trust controls and corrective governance.

It sets boundaries for security handling, incident response, and recovery without implying certification, approval, deployment, or execution.

## 26.1 Nexus Governance Doctrine

### 26.1.1 Governance by Record

Governance by record is the doctrine that Nexus governance shall operate through recorded status, recorded authority, recorded role, recorded review, recorded evidence, recorded dependency, recorded boundary, recorded correction, recorded recall, recorded archive, and recorded non-current status rather than informal assertion, implied authority, reputational inference, institutional proximity, sponsor visibility, provider participation, public authority attendance, capital-reader presence, or technical capability.

Governance by record means that a Nexus object, decision surface, review pathway, public-safe release, Registry status, Marketplace listing, Grid input, TRL context, National Portfolio object, Nexus Universe output, Campaign object, Academy object, Studio workflow, DRI output, Observatory summary, finance-readiness record, public authority learning record, safeguard record, handoff package, correction action, incident response, or archive state shall have its meaning determined by the applicable record and not by assumption.

A Governance-by-Record Control should identify:

1. governed object, including software, data, model, ontology, API, dashboard, Report, Campaign material, Academy object, Studio workflow, DRI record, Observatory record, Registry record, Marketplace listing, Grid input, TRL context, National Portfolio object, Nexus Universe output, public authority learning record, finance-readiness record, safeguard record, handoff record, correction record, or archive record;
2. record class, including intake record, review record, evidence record, data-use record, AI-use record, public-safe record, safeguard record, public authority boundary record, finance boundary record, procurement boundary record, provider-neutrality record, sponsor-boundary record, handoff dependency record, incident record, correction record, withdrawal record, recall record, archive record, or non-current notice;
3. status fields, including draft, reviewed, restricted, public-safe, controlled-public, supported, unsupported, suspended, deprecated, corrected, superseded, withdrawn, recalled, archived, sealed, deletion-required, or non-continuing;
4. authority fields, including steward, reviewer, maintainer, contributor, lawful recipient, public authority learner, finance-readiness reader, sponsor supporter, provider contributor, archive steward, and correction steward, together with the limits of each role;
5. dependency fields, including data dependency, method dependency, model dependency, cyber dependency, public authority dependency, legal dependency, finance dependency, insurance dependency, donor dependency, public finance dependency, procurement dependency, safeguard dependency, provider dependency, sponsor dependency, handoff dependency, correction dependency, and archive dependency;
6. boundary notices, confirming that the record defines status but does not create approval, certification, public authority action, procurement approval, financeability, insurability, donor commitment, public finance allocation, consent, deployment authorization, operational command, or execution unless separately and lawfully recorded by a competent actor.

Governance by record is the core validity discipline of Nexus. What is not recorded shall not be presumed.

### 26.1.2 Governance by Review

Governance by review is the doctrine that Nexus objects, outputs, releases, listings, Registry statuses, Grid inputs, Studio workflows, Reports, Campaigns, Academy materials, DRI outputs, Observatory summaries, public authority learning materials, finance-readiness records, safeguard records, handoff packages, infrastructure environments, AI workflows, cyber objects, data objects, and archives shall be subject to appropriate review before they are relied upon within Nexus scope.

Review may be technical, evidentiary, data-related, AI-related, cyber-related, privacy-related, public-safe, safeguard-related, accessibility-related, geospatial, legal-boundary, public-authority-boundary, finance-boundary, procurement-boundary, provider-neutrality, sponsor-boundary, handoff, correction, recall, or archive review. Review shall be proportional to sensitivity, risk, release class, data class, AI-use label, public authority proximity, finance-readiness proximity, safeguard impact, and handoff risk.

A Governance-by-Review Control should identify:

1. reviewed object, including dataset, model, software, Report, dashboard, Studio workflow, DRI output, Observatory summary, Registry record, Marketplace listing, Grid input, Campaign object, Academy object, National Portfolio object, Nexus Universe output, infrastructure environment, public authority learning material, finance-readiness material, safeguard record, handoff package, or archive object;
2. review class, including evidence review, data review, method review, AI review, model review, system review, cyber review, privacy review, public-safe review, accessibility review, safeguard review, community review where appropriate, Indigenous protocol review where applicable, public authority boundary review, finance and insurance boundary review, donor and public finance boundary review, procurement boundary review, provider-neutrality review, sponsor-boundary review, legal boundary review, handoff review, correction review, and archive review;
3. review status, including not reviewed, review pending, reviewed with limitations, reviewed with conditions, approved for limited Nexus use, public-safe reviewed, restricted, rejected, suspended, corrected, withdrawn, recalled, archived, or non-continuing;
4. review findings, including evidence gaps, data gaps, method gaps, AI limitations, cyber risks, privacy risks, public-safe risks, safeguard conditions, public authority dependencies, finance dependencies, procurement limits, provider-neutrality risks, sponsor risks, legal dependencies, handoff restrictions, correction requirements, and archive requirements;
5. review limits, including review-not-certification, review-not-public-authority-approval, review-not-procurement-approval, review-not-financeability, review-not-insurability, review-not-consent, review-not-deployment-authorization, and review-not-execution;
6. boundary notices, confirming that governance review supports bounded Nexus use and correctionability but does not create certification, public authority action, procurement approval, financeability, insurability, donor commitment, public finance allocation, consent, deployment authorization, operational command, or execution.

Governance by review ensures that Nexus work is examined before it is released, routed, displayed, or handed off, while preserving the difference between review and authority.

### 26.1.3 Governance by Role Separation

Governance by role separation is the doctrine that Nexus governance shall maintain clear separation among public-good stewardship, technical evidence formation, legitimacy stewardship, finance-readiness, public authority learning, standards-interface work, provider contribution, sponsor support, community participation, academic contribution, infrastructure support, National Node stewardship, enterprise handoff, project execution, public authority action, procurement, finance, insurance, donor allocation, public finance allocation, and archive.

Role separation prevents institutional collapse, hidden agency, authority overclaim, sponsor capture, provider capture, public authority substitution, finance execution, procurement bias, consent overclaim, and execution by implication. Each actor may contribute within its recorded role, but no actor acquires unrecorded authority merely through proximity, participation, support, contribution, visibility, hosting, or handoff.

A Governance-by-Role-Separation Control should identify:

1. actor class, including The Global Centre for Risk and Innovation (GCRI), The Global Risks Forum (GRF), The Global Risks Alliance (GRA), protocol authority, National Nexus Consortium, Regional Nexus Consortium, Global Nexus Consortium, National Node, National Consortium Company, Project SPV, public authority, provider, sponsor, university, lab, community actor, Indigenous actor where applicable, donor, capital reader, insurer, operator, contractor, maintainer, contributor, reviewer, or archive steward;
2. recorded role, including technical evidence steward, public-good legitimacy steward, finance-readiness steward, public authority learner, standards-interface actor, provider contributor, sponsor supporter, community participant, researcher, maintainer, reviewer, lawful recipient, archive steward, or execution-capable actor outside Nexus;
3. role limits, including non-execution, no public authority substitution, no procurement authority, no finance execution, no insurance approval, no donor allocation, no public finance allocation, no certification by implication, no consent by implication, no provider validation, no sponsor control, and no hidden agency;
4. interface conditions, including records required, review required, public-safe controls, safeguard controls, conflict controls, dependency registers, handoff packages, recipient responsibilities, correction pathways, and archive rules;
5. role-collapse risks, including sponsor control, provider validation, public authority overclaim, finance overclaim, procurement overclaim, community consent overclaim, standards overclaim, maintenance-as-certification, hosting-as-approval, handoff-as-execution, and archive-as-current-authority;
6. boundary notices, confirming that participation, contribution, support, review, hosting, listing, registration, readiness, learning, or handoff does not merge roles, transfer authority, create agency, create liability, authorize deployment, command operations, or execute implementation.

Governance by role separation is the institutional firewall of Nexus.

### 26.1.4 Governance by Public-Safe Controls

Governance by public-safe controls is the doctrine that Nexus shall control what may be communicated, published, displayed, translated, summarized, mapped, visualized, listed, registered, archived, or handed off to different audiences so that public-good communication does not expose protected knowledge, sensitive data, unsafe geospatial detail, public authority-sensitive material, health-sensitive information, humanitarian-sensitive information, cyber-sensitive information, infrastructure-sensitive information, finance-sensitive information, community-sensitive information, youth-sensitive information, Indigenous protocol-sensitive information where applicable, or misleading authority claims.

Public-safe controls shall apply to Reports, dashboards, public-safe atlases, Campaign materials, Academy materials, Studio summaries, DRI summaries, Observatory summaries, Registry displays, Marketplace listings, Grid summaries, National Portfolio summaries, Nexus Universe outputs, public authority learning summaries, finance-readiness summaries, donor-readiness summaries, public finance learning summaries, safeguard summaries, correction notices, recall notices, archive notices, and handoff-awareness materials.

A Governance-by-Public-Safe-Control should identify:

1. release object, including Report, dashboard, map, atlas, Campaign page, Academy object, Studio summary, DRI output, Observatory summary, Registry display, Marketplace listing, Grid summary, National Portfolio object, Nexus Universe output, public authority learning material, finance-readiness material, safeguard record, correction notice, recall notice, archive notice, or handoff summary;
2. release class, including public, controlled-public, National Node-visible, community-review-only, public authority learning-only, secure-room summary, data-room summary, protected knowledge room summary, finance-readiness-only, donor-reader-only, public finance learning-only, handoff-recipient-only, restricted, archive-only, sealed, deletion-required, or non-current;
3. sensitivity controls, including redaction, aggregation, anonymization, pseudonymization, geospatial masking, protected knowledge exclusion, delayed release, metadata-only release, plain-language transformation, accessibility review, limitation language, uncertainty language, non-stigmatizing language, no-warning language, no-command language, and no-execution language;
4. review requirements, including data review, AI-use review, cyber review, privacy review, geospatial review, public-safe review, accessibility review, safeguard review, community review where appropriate, Indigenous protocol review where applicable, public authority boundary review, finance and insurance boundary review, donor and public finance boundary review, legal boundary review, correction review, and archive review;
5. public-safe failure controls, including claims freeze, data freeze, technical freeze, release suspension, Marketplace delisting, Registry status update, Report correction, dashboard correction, public repair, withdrawal, recall, archive, sealing, deletion where required, and non-continuation;
6. boundary notices, confirming that public-safe release is not full disclosure, official warning, public authority decision, procurement approval, financeability, insurability, donor commitment, public finance allocation, consent, deployment authorization, operational command, or execution.

Governance by public-safe controls allows Nexus to publish responsibly without making openness unsafe or authoritative.

### 26.1.5 Governance by Safeguards

Governance by safeguards is the doctrine that Nexus governance shall protect people, communities, youth, persons with disabilities, humanitarian-sensitive populations, Indigenous participants and knowledge systems where applicable, protected knowledge holders, public-interest participants, affected stakeholders, and place-based actors from extraction, exposure, misrepresentation, tokenization, consent overclaim, unsafe publication, unsafe geospatial disclosure, AI misuse, data misuse, public authority misuse, finance misuse, procurement misuse, and handoff misuse.

Safeguards are not decorative ethics. They are governance controls. They shall affect intake, review, release, display, translation, accessibility, data-use labels, AI-use labels, secure-room rules, public-safe summaries, Registry fields, Marketplace listings, Grid inputs, Campaign pages, Academy materials, Studio workflows, National Portfolio objects, Nexus Universe outputs, handoff packages, correction pathways, recall pathways, and archives.

A Governance-by-Safeguards Control should identify:

1. safeguard class, including community safeguard, Indigenous protocol-sensitive safeguard where applicable, protected knowledge safeguard, youth safeguard, disability inclusion safeguard, humanitarian sensitivity safeguard, health sensitivity safeguard, geospatial safeguard, data safeguard, AI-use safeguard, public-safe reporting safeguard, public authority boundary safeguard, finance boundary safeguard, and handoff safeguard;
2. affected object or context, including data, map, story, image, quote, Report, dashboard, Campaign, Academy object, Studio workflow, DRI output, Observatory summary, National Portfolio object, Registry record, Marketplace listing, Grid input, Nexus Universe output, public authority learning material, finance-readiness material, or handoff package;
3. control action, including restrict, redact, anonymize, aggregate, mask, translate carefully, remove image, remove quote, require protected knowledge room, require secure room, require data room, prohibit AI training, prohibit public display, limit attribution, add consent-boundary notice, add correction channel, withdraw, recall, seal, delete where required, or archive;
4. review pathway, including safeguard review, public-safe review, privacy review, geospatial review, Indigenous protocol review where applicable, accessibility review, humanitarian sensitivity review, public authority boundary review, finance boundary review, legal boundary review, correction review, recall review, and archive review;
5. safeguard boundary rules, including participation-not-consent, display-not-consent, protected-knowledge-availability-not-permission, accessibility-format-not-new-license, public-safe-summary-not-full-disclosure, safeguard-review-not-public-authority-approval, and handoff-not-consent;
6. boundary notices, confirming that safeguards support legitimacy, protection, and correctionability but do not create consent, endorsement, public authority approval, procurement approval, financeability, insurability, deployment authorization, operational command, or execution.

Governance by safeguards ensures that Nexus public-good ambition remains non-extractive and accountable to affected contexts.

### 26.1.6 Governance by Correction

Governance by correction is the doctrine that Nexus governance shall treat errors, omissions, overclaims, unsafe releases, stale records, boundary failures, data defects, AI defects, model failures, cyber incidents, privacy incidents, protected knowledge exposure, public authority overclaim, finance overclaim, procurement overclaim, consent overclaim, handoff overclaim, execution overclaim, and archive misuse as correctable governance events.

Correction is not reputational weakness. It is trust infrastructure. Nexus governance shall preserve visible pathways for patch, erratum, addendum, revision, supersession, downgrade, suspension, withdrawal, retraction where necessary, recall, public repair, archive, sealing, deletion where required, and non-continuation.

A Governance-by-Correction Control should identify:

1. correction object, including data object, model, software, dashboard, API, Report, Campaign material, Academy object, Studio workflow, DRI output, Observatory summary, Registry record, Marketplace listing, Grid input, National Portfolio object, Nexus Universe output, public authority learning record, finance-readiness record, safeguard record, handoff package, infrastructure record, support record, reliability record, or archive record;
2. correction trigger, including factual error, data error, method error, model error, AI error, cyber incident, privacy incident, public-safe incident, protected knowledge incident, accessibility failure, safeguard failure, public authority boundary incident, finance boundary incident, procurement boundary incident, provider validation incident, sponsor control incident, consent overclaim incident, handoff overclaim incident, execution overclaim incident, stale status, non-current status, or archive misuse;
3. correction action, including patch, erratum, addendum, revision, supersession, downgrade, suspension, withdrawal, retraction where necessary, recall, public repair, Registry update, Marketplace update, Grid update, Report update, National Portfolio update, handoff notice, archive update, sealing, deletion where required, or non-continuation;
4. propagation pathway, including mirrors, repositories, public-safe summaries, offline packages, low-bandwidth materials, translations, Registry records, Marketplace listings, Grid records, Campaigns, Academy materials, Studio workflows, DRI outputs, Observatory summaries, public authority learning materials, finance-readiness materials, handoff recipients, archives, and successor objects;
5. governance response, including stop-the-line, claims freeze, data freeze, technical freeze, model freeze, API freeze, Marketplace delisting, Registry status update, public-safe notice, handoff recall, archive, reinstatement, and recurrence-prevention action;
6. boundary notices, confirming that correction restores record integrity but does not create warranty, certification, public authority approval, procurement approval, financeability, insurability, deployment authorization, operational command, or execution.

Governance by correction keeps Nexus trustworthy by making repair part of governance rather than an exception to it.

### 26.1.7 Governance Without Command by Implication

Governance without command by implication is the doctrine that Nexus governance shall not be represented as operational command, public authority command, emergency command, public warning, infrastructure instruction, clinical instruction, public health instruction, procurement direction, finance direction, insurance direction, donor allocation direction, public finance direction, deployment instruction, implementation instruction, or execution instruction.

Nexus governance may set internal public-good controls, review pathways, participation rules, release rules, safeguard rules, Registry rules, Marketplace rules, Grid rules, handoff rules, archive rules, and correction rules. It may define what Nexus records mean and what they do not mean. It shall not command external actors to act unless a separate lawful actor acts under its own authority outside Nexus.

A Governance-Without-Command Control should identify:

1. governance object, including doctrine, rule, review, release, listing, Registry status, Grid input, public-safe summary, safeguard record, public authority learning record, finance-readiness record, handoff package, correction notice, recall notice, archive notice, or non-current notice;
2. command-risk context, including public authority action, public warning, emergency command, cyber incident command, infrastructure operation, public health decision, medical decision, procurement action, finance or insurance action, donor action, public finance action, community consent, deployment, implementation, or execution;
3. permitted meaning, including internal governance, public-good record status, release control, review status, dependency awareness, learning, readiness question, safeguard condition, correction notice, archive status, and handoff dependency awareness;
4. prohibited meaning, including command, warning, order, directive, approval, certification, procurement instruction, financial instruction, insurance instruction, donor allocation, public finance allocation, consent determination, deployment authorization, operational instruction, and execution instruction;
5. display controls, including no-command notice, no-warning notice, no-public-authority-action notice, no-procurement notice, no-finance notice, no-public-finance notice, no-consent notice, no-deployment notice, no-execution notice, and correction channel;
6. boundary notices, confirming that Nexus governance governs Nexus records and participation only and does not command external operations, public authorities, markets, funders, insurers, communities, providers, or execution actors.

Governance without command preserves the difference between institutional trust controls and operational authority.

### 26.1.8 Governance as Operating Trust

Governance as operating trust is the doctrine that Nexus governance exists to make public-good work trustworthy in operation: evidence-bearing, role-separated, public-safe, safeguard-bound, data-governed, AI-controlled, cyber-resilient, privacy-aware, provider-neutral, sponsor-controlled, public authority-boundary-safe, finance-boundary-safe, procurement-neutral, handoff-aware, correctionable, and archivable.

Operating trust is not brand trust, promotional trust, institutional prestige, or authority by reputation. It is the accumulated result of records, reviews, controls, safeguards, boundary notices, corrections, and archives operating together.

An Operating Trust Record should identify:

1. trust basis, including record discipline, evidence review, data controls, AI controls, cyber controls, privacy controls, public-safe controls, safeguards, role separation, public authority boundary controls, finance boundary controls, procurement neutrality, provider controls, sponsor controls, handoff controls, correction controls, and archive controls;
2. trust object, including Report, Registry record, Marketplace listing, Grid input, Campaign, Academy object, Studio workflow, DRI output, Observatory summary, National Portfolio object, Nexus Universe output, public authority learning record, finance-readiness record, safeguard record, handoff package, or archive;
3. trust status, including draft, reviewed, public-safe, restricted, supported, corrected, downgraded, suspended, withdrawn, recalled, archived, non-current, or non-continuing;
4. trust limits, including trust-within-recorded-scope, no-certification-by-default, no-public-authority-approval, no-procurement-approval, no-financeability, no-insurability, no-donor-commitment, no-public-finance-allocation, no-consent, no-deployment-authorization, and no-execution;
5. trust maintenance, including monitoring, review cadence, correction pathway, incident response, stop-the-line, recall, archive, public repair, support status, reliability status, and non-current notices;
6. boundary notices, confirming that operating trust is created through governance controls and does not become legal approval, public authority action, market assurance, service warranty, deployment authorization, operational command, or execution.

The final Nexus Governance Doctrine rule is: Nexus governance operates by record, review, role separation, public-safe controls, safeguards, correction, no-command discipline, and operating trust. These doctrines allow Nexus to govern complex public-good work without converting governance into command, approval, certification, procurement, finance, insurance, public finance allocation, consent, deployment authorization, or execution by implication.

## 26.2 Control Families

### 26.2.1 Evidence Controls

A Privacy Control Record should identify data subject context where appropriate, data class, lawful or recorded basis where required, minimization rule, access restriction, retention rule, deletion rule, public-safe transformation, correction pathway, archive status, and boundary notices. Privacy controls shall prevent personal or sensitive information from being treated as open data, AI-training material, public display material, consent, public authority approval, or handoff authorization by default.

### 26.2.6 Public-Safe Controls

Public-safe controls govern whether information may be publicly released, controlled-publicly released, summarized, redacted, masked, translated, mapped, listed, registered, displayed, archived, or handed off. They apply to all outputs that may reach public, participant, public authority learning, finance-readiness, donor, public finance, Marketplace, Registry, Grid, National Portfolio, Nexus Universe, or handoff audiences.

A Public-Safe Control Record should identify source sensitivity, release class, transformation controls, required notices, review status, correction pathway, recall pathway, archive rule, and boundary notices. Public-safe controls shall prevent release from becoming full disclosure, official warning, public authority action, procurement approval, financeability, insurability, consent, deployment authorization, or execution.

### 26.2.7 Safeguard Controls

Safeguard controls govern community participation, Indigenous protocols where applicable, protected knowledge, youth safeguards, disability inclusion, humanitarian sensitivity, health sensitivity, local context, geospatial sensitivity, non-extractive knowledge practices, consent boundaries, attribution, correction channels, public-safe summaries, handoff restrictions, and archive.

A Safeguard Control Record should identify safeguard class, affected context, controls applied, review status, consent boundary, correction pathway, archive rule, and boundary notices. Safeguard controls shall prevent participation, display, or review from becoming consent, endorsement, public authority approval, procurement approval, deployment authorization, or execution.

### 26.2.8 Public Authority Boundary Controls

Public authority boundary controls govern public authority participation, public authority learning records, non-decision rooms, official action outside Nexus, public finance outside Nexus, permits and approvals outside Nexus, public warnings outside Nexus, emergency command outside Nexus, public authority-sensitive data, public authority-sensitive workloads, and public authority dependency notes.

A Public Authority Boundary Control Record should identify public authority context, learning status, dependency status, no-decision notice, public-safe status, correction pathway, archive rule, and boundary notices. These controls shall prevent public authority learning from becoming public authority action, policy adoption, regulation, procurement approval, public finance allocation, warning, command, deployment authorization, or execution.

### 26.2.9 Finance Boundary Controls

finance boundary controls govern capital-readability, insurance-readiness questions, donor-readiness questions, public finance relevance questions, assumptions registers, dependency registers, diligence-gap registers, no-reliance statements, non-solicitation, non-transactionality, regulated-perimeter escalation, competition compliance, confidentiality controls, and handoff restrictions.

A Finance Boundary Control Record should identify finance-readiness object, reader class, assumptions, dependencies, diligence gaps, no-reliance status, non-solicitation notice, non-transactional status, correction pathway, archive rule, and boundary notices. These controls shall prevent readiness from becoming finance, insurance, underwriting, donor commitment, public finance allocation, investment advice, transaction, or execution.

### 26.2.10 Procurement Boundary Controls

Procurement boundary controls govern no preferred provider, no procurement recommendation, no supplier approval, no vendor validation, no tender support by implication, independent diligence requirements, provider contribution controls, Marketplace listing controls, public authority procurement boundaries, and handoff procurement notices.

A Procurement Boundary Control Record should identify provider or supplier context, listing or handoff object, procurement-risk context, no-procurement notice, provider-neutrality status, conflict status, correction pathway, archive rule, and boundary notices. These controls shall prevent Nexus discovery, evidence, readiness, or handoff from becoming procurement recommendation, supplier selection, tender support, or procurement decision.

### 26.2.11 Provider Controls

Provider controls govern provider contributions, technical input, cloud support, software support, hardware support, data support, AI support, security support, telecom support, equipment support, APIs, demos, documentation, Academy support, Studio support, Nexus Universe support, Foundry support, Marketplace display, Registry references, conflicts, portability, dependency records, and no-validation notices.

A Provider Control Record should identify provider class, contribution, dependency, support status, neutrality controls, display controls, conflicts, correction pathway, archive rule, and boundary notices. Provider controls shall prevent contribution from becoming provider validation, endorsement, procurement preference, public authority approval, financeability, insurability, deployment authorization, or execution.

### 26.2.12 Sponsor Controls

Sponsor controls govern sponsor support, in-kind support, funding support where lawful, cloud credits, equipment support, venue support, communications support, Academy support, Campaign support, Nexus Universe support, Foundry support, display language, logo use, quote use, conflicts, no-control notices, no-pay-to-influence notices, no-routing-priority notices, correction, withdrawal, and archive.

A Sponsor Control Record should identify sponsor, support type, conditions, display status, conflict status, no-control notice, no-procurement notice, no-finance notice, correction pathway, archive rule, and boundary notices. Sponsor controls shall prevent support from becoming control, endorsement, procurement preference, financeability, public authority approval, donor commitment, public finance allocation, deployment authorization, or execution.

### 26.2.13 Handoff Controls

Handoff controls govern handoff intake, handoff classification, handoff review, handoff recipient records, handoff dependency registers, handoff correction, handoff recall, handoff archive, recipient responsibilities, no-authority-transfer notices, no-execution notices, procurement boundaries, finance boundaries, public authority boundaries, safeguard boundaries, and correction pathways.

A Handoff Control Record should identify handoff package, recipient, classification, dependencies, restrictions, responsibilities, correction pathway, recall pathway, archive rule, and boundary notices. Handoff controls shall prevent context, evidence, readiness, or dependency transfer from becoming authorization, approval, finance, procurement, public authority action, consent, deployment authorization, or execution.

### 26.2.14 Archive Controls

Archive controls govern archive object classes, archive metadata, archive access classes, archive-not-current notices, historical use notes, successor links, correction history, license status, public-safe status, retention rules, deletion rules, sealing, recall status, withdrawal status, non-current status, and non-continuation.

An Archive Control Record should identify archived object, archive class, access class, retention, deletion, successor link, correction history, reuse restrictions, public-safe status, and boundary notices. Archive controls shall prevent archived materials from being treated as current authority, approval, certification, procurement status, financeability, insurability, deployment authorization, or execution.

The final Control Families rule is: Nexus control families include evidence controls, data controls, AI controls, cyber controls, privacy controls, public-safe controls, safeguard controls, public authority boundary controls, finance boundary controls, procurement boundary controls, provider controls, sponsor controls, handoff controls, and archive controls. These controls make Nexus governable across the full public-good stack while preventing records, reviews, releases, contributions, support, listings, readiness, handoff, and archives from becoming approval, certification, procurement, finance, insurance, public finance allocation, consent, deployment authorization, operational command, or execution by implication.

## 26.3 Security and Privacy

### 26.3.1 Zero-Trust Principles

Zero-trust principles are the security and privacy baseline that Nexus infrastructure, repositories, rooms, workflows, APIs, dashboards, datasets, models, AI systems, Studio environments, DRI workflows, Observatory workflows, Registry workflows, Marketplace workflows, Grid workflows, Campaign platforms, Academy platforms, public authority learning rooms, finance-readiness rooms, and handoff environments shall not assume trust merely because an actor, system, provider, sponsor, maintainer, contributor, public authority learner, or recipient is inside a Nexus pathway.

A Zero-Trust Principle Record should identify the protected object, identity controls, access controls, workload controls, data controls, monitoring controls, logging controls, incident response controls, correction controls, and archive rule. Zero-trust principles support security and privacy but do not create security certification, compliance approval, public authority approval, procurement approval, deployment authorization, or execution.

### 26.3.2 Identity and Access Management

Identity and access management governs the assignment, verification, restriction, review, revocation, correction, and archive of identities, accounts, service accounts, keys, credentials, role classes, contributor roles, maintainer roles, reviewer roles, public authority learner roles, finance-reader roles, sponsor observer roles, provider contributor roles, community participant roles, secure-room participants, data-room participants, protected knowledge room participants, handoff recipients, and archive stewards.

An Identity and Access Management Record should identify identity class, role, access scope, purpose, duration, verification method, approval steward, restrictions, logs, recertification schedule, revocation conditions, correction pathway, and archive rule. Identity and access management does not create authority beyond recorded access.

### 26.3.3 Least Privilege

Least privilege is the rule that Nexus actors, systems, workflows, APIs, AI agents, service accounts, maintainers, contributors, reviewers, room participants, public authority learners, finance readers, providers, sponsors, and handoff recipients shall receive only the minimum access required for the recorded purpose and no broader access by convenience, prestige, sponsorship, institutional status, provider role, or public authority proximity.

A Least Privilege Record should identify access requested, access granted, denied permissions, purpose limitation, time limitation, no-download restrictions, no-write-back restrictions, no-AI-use restrictions where applicable, review cadence, revocation trigger, and archive rule.

### 26.3.4 Encryption Where Appropriate

Encryption where appropriate is the rule that Nexus shall apply encryption at rest, encryption in transit, key management, secret protection, encrypted backups, secure-room encryption, data-room encryption, protected knowledge encryption, sovereign compute encryption, repository signing where appropriate, credential protection, and secure communication controls where sensitivity, risk, law, data sovereignty, public authority sensitivity, protected knowledge, cyber risk, privacy, or handoff context requires.

An Encryption Control Record should identify protected object, encryption scope, key steward, key rotation, access controls, backup controls, recovery controls, incident response, correction pathway, and archive rule. Encryption is a security control, not a security certification or authorization.

### 26.3.5 Secure Repositories

Secure repositories are repositories governed by access controls, branch protections where applicable, signed commits or releases where appropriate, dependency review, secret scanning, vulnerability scanning, issue tracking, maintainer roles, contribution rules, license notices, data-use labels, AI-use labels, public-safe controls, protected knowledge restrictions, correction pathways, withdrawal, recall, and archive.

A Secure Repository Record should identify repository class, steward, access model, protection controls, dependency controls, secret controls, release controls, public-safe controls, incident pathway, correction pathway, and archive rule. Secure repositories support safer operations but do not certify downstream use.

### 26.3.6 Secret Scanning

Secret scanning is the security control used to detect, restrict, revoke, rotate, correct, and archive exposed credentials, API keys, tokens, private keys, passwords, certificates, signing keys, cloud keys, repository keys, room access keys, service account credentials, webhook secrets, and other secrets in Nexus repositories, logs, workflows, messages, dashboards, notebooks, Studio workflows, DRI workflows, Observatory workflows, Registry workflows, Marketplace workflows, Grid workflows, and handoff packages.

A Secret Scanning Record should identify scan scope, secret type, exposure status, containment action, rotation action, affected objects, notification pathway, correction pathway, archive rule, and boundary notices. Secret scanning is incident prevention and correction, not security certification.

### 26.3.7 Dependency Scanning

Dependency scanning is the security and operational control used to identify vulnerable, outdated, unsupported, restricted, mislicensed, incompatible, abandoned, or risky dependencies in Nexus software, models, APIs, dashboards, Studio workflows, AI workflows, infrastructure-as-code, container images, notebooks, Academy labs, Campaign platforms, Registry workflows, Marketplace workflows, Grid tooling, DRI workflows, Observatory workflows, and handoff packages.

A Dependency Scanning Record should identify dependency, version, vulnerability or risk, license status, support status, affected object, severity, remediation, exception where applicable, correction pathway, and archive rule. Dependency scanning does not certify security or compliance.

### 26.3.8 SBOM Literacy

SBOM literacy is the security and supply-chain discipline through which Nexus records, reads, explains, and uses Software Bills of Materials and related dependency records to understand software composition, supply-chain exposure, vulnerability context, licensing context, support status, provider dependency, handoff dependency, and correction obligations.

An SBOM Literacy Record should identify software object, SBOM status, dependency scope, vulnerability linkage, license linkage, maintainer linkage, support status, handoff relevance, correction pathway, and archive rule. SBOM literacy helps understand software risk but is not certification, procurement approval, security approval, or deployment authorization.

### 26.3.9 Incident Response

Incident response in security and privacy is the process for detecting, containing, correcting, reporting where appropriate, withdrawing, recalling, sealing, deleting where required, archiving, and learning from security incidents, privacy incidents, data incidents, AI incidents, protected knowledge incidents, access incidents, key incidents, repository incidents, API incidents, infrastructure incidents, public-safe incidents, and handoff incidents.

A Security and Privacy Incident Response Record should identify incident class, affected objects, severity, containment, root cause, remediation, notification pathway where appropriate, correction propagation, Registry update, Marketplace update, Grid update, handoff recall where required, archive rule, and recurrence-prevention action.

### 26.3.10 Access Recertification

Access recertification is the periodic or event-triggered review of access rights, role assignments, room access, repository permissions, API permissions, service accounts, keys, public authority learner access, finance-reader access, provider contributor access, sponsor observer access, secure-room access, data-room access, protected knowledge room access, handoff recipient access, and archive access.

An Access Recertification Record should identify access reviewed, current role, purpose, last use where appropriate, continued need, removal decision, restriction decision, escalation, revocation, correction pathway, and archive rule. Access recertification prevents privilege drift and does not create broader authority.

### 26.3.11 Deletion, Sealing, and Archive

Deletion, sealing, and archive are the security and privacy lifecycle controls used when data, secrets, logs, records, models, outputs, caches, embeddings, indexes, protected knowledge, personal information, public authority-sensitive material, health-sensitive material, cyber-sensitive material, handoff packages, or other Nexus objects must be deleted, sealed, restricted, preserved, marked non-current, or archived under recorded rules.

A Deletion, Sealing, and Archive Record should identify object, trigger, legal or governance basis, retention status, deletion action, sealing action, archive class, access restrictions, correction history, successor link where applicable, verification, and boundary notices. Deletion, sealing, and archive preserve safety and status truth; they do not create current authority or approval.

The final Security and Privacy rule is: Nexus security and privacy require zero-trust principles, identity and access management, least privilege, encryption where appropriate, secure repositories, secret scanning, dependency scanning, SBOM literacy, incident response, access recertification, and deletion, sealing, and archive discipline. These controls protect Nexus records, infrastructure, data, AI systems, repositories, rooms, workflows, and handoff packages while preventing security review, privacy handling, access, scanning, SBOMs, incident response, or archive from becoming security certification, public authority approval, procurement approval, deployment authorization, operational command, or execution by implication.

A License Status Record should identify license class, rights holder where appropriate, contribution terms, reuse permission, prohibited use, AI-use status, data-use status, attribution rule, expiration where applicable, correction pathway, and archive rule.

### 26.7.9 Public-Safe Status

public-safe status is the archive record identifying whether an archived object may remain public, controlled-public, restricted, metadata-only, secure-room-only, data-room-only, protected knowledge room-only, handoff-recipient-only, sealed, deleted, or archive-only, and what public-safe transformations, redactions, limitation notices, non-current notices, or recall notices apply.

A Public-Safe Archive Status Record should identify source sensitivity, release class, redactions, masking, excluded material, limitation notices, no-warning notices, no-command notices, correction history, recall status, and archive access class.

### 26.7.10 Retention Rule

Retention rule is the archive rule determining how long an archived object shall be preserved, when it shall be reviewed, whether it shall be sealed, whether it shall be deleted, whether only metadata shall be retained, whether protected knowledge restrictions apply, whether legal hold applies, whether public-safe access continues, and whether successor links remain active.

A Retention Rule Record should identify archive object, retention period or condition, legal or governance basis, review cadence, deletion trigger, sealing trigger, metadata-only trigger, public-safe review trigger, correction trigger, and archive steward.

The final Archive Governance rule is: Nexus archive governance requires archive objects, archive metadata, archive access classes, archive-not-current notices, historical use notes, successor links, correction histories, license status, public-safe status, and retention rules. These controls preserve institutional memory, correctionability, provenance, rights, public-safe status, and historical learning while preventing archived objects from being treated as current authority, approval, certification, procurement status, financeability, insurability, public authority action, deployment authorization, operational command, or execution by implication.
