# XXVI. SECURITY

## Summary

This page defines the Nexus Universe security framework for protecting evidence, systems, data, rooms, records, and public trust across the full cycle. It explains how security, privacy, sovereignty, and correction controls apply from Foundry and BuildGrid through Nexus Core, dashboards, Grid inputs, Rails routes, handoff packages, retention, and archive.

It covers three core areas:

* security controls for identity and access, zero-trust architecture, secure collaboration, controlled rooms, cyber ranges, Foundry work, BuildGrid work, logging, monitoring, telemetry, incident response, and secure teardown;
* data and privacy controls for classification, personal and rights-bearing data, no-PII public release rules, sovereign data zones, localization, compute-to-data, cross-border transfer review, protected knowledge, synthetic data, and re-identification risk;
* trust-preserving correction rules for breach handling, notification review, retention, archive discipline, public-safe notices, and correction of security, privacy, and data incidents.

## 26.1 Security Baseline

### 26.1.1 Security Baseline Function

26.1.1.1 **Security Baseline** defines the minimum security posture required for Nexus Universe, Nexus Foundry, BuildGrid, Nexus Core, Stack Workspaces, controlled rooms, public dashboards, repositories, data rooms, public authority learning rooms, capital-reader rooms, insurance-readiness rooms, community safeguard rooms, media studios, cyber range environments, digital twin theatres, Evidence Packs, telemetry stores, Stack Passports, public-safe reports, Grid inputs, Rails routes, and lawful handoff packages.

26.1.1.2 The Security Baseline exists because Nexus Universe handles high-performance systems, sensitive evidence, telemetry, AI systems, cyber exercises, public authority learning, sovereign data, protected knowledge, community-sensitive information, infrastructure-sensitive information, capital-readiness materials, insurance-readiness evidence, and public-facing records. Security failure can become evidence failure, public-trust failure, privacy failure, public authority boundary failure, capital-readiness boundary failure, community safeguard failure, or lawful handoff failure.

26.1.1.3 Security must be treated as core validation infrastructure, not administrative overhead. A stack, dashboard, room, repository, data workflow, or handoff package that cannot preserve security appropriate to its risk class cannot be treated as trustworthy merely because its public performance is strong.

### 26.1.2 Security Baseline Requirements

26.1.2.1 The Security Baseline should include identity management, role-based access control, least privilege, zero-trust architecture, secure collaboration tooling, encryption where appropriate, logging, monitoring, vulnerability management, incident response, secrets management, software supply-chain assurance, endpoint controls, network segmentation, data classification, secure repositories, secure rooms, output review, backup discipline, retention discipline, archive security, and secure teardown.

26.1.2.2 Security requirements must be risk-adjusted by access class, data class, stack class, room class, participant role, public exposure, cyber sensitivity, public authority sensitivity, protected knowledge sensitivity, sovereign data status, privacy sensitivity, and lawful handoff relevance.

26.1.2.3 Security controls should apply before, during, and after the live Nexus Universe cycle, including the one-year mobilization phase, Foundry preparation, BuildGrid work, Nexus Core integration, live validation, public dashboarding, correction, Grid input review, Rails routing, handoff preparation, teardown, retention, and archive.

### 26.1.3 Security Baseline Records

26.1.3.1 Security Baseline Records should identify applicable system, room, stack, repository, dashboard, dataset, workflow, or output; required controls; implemented controls; gaps; exceptions; risk owner; correction status; incident history; and archive reference.

26.1.3.2 Security exceptions must be recorded, justified, time-limited, reviewed, and corrected. Unrecorded exceptions are not valid exceptions.

### 26.1.4 Security Baseline Boundary

26.1.4.1 Security Baseline compliance within Nexus Universe does not create external cybersecurity certification, legal compliance approval, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.1.4.2 The Security Baseline protects Nexus Universe records and operations; it does not certify external use.

## 26.2 Identity, Access, and Least Privilege

### 26.2.1 Identity and Access Function

26.2.1.1 **Identity, Access, and Least Privilege** governs how individuals, teams, sponsors, providers, public authorities, capital readers, insurance readers, media actors, community participants, youth participants, reviewers, stewards, Competence Cells, Foundry participants, BuildGrid contributors, stack operators, and lawful handoff reviewers are identified, authenticated, authorized, limited, monitored, and removed from Nexus Universe systems and rooms.

26.2.1.2 Identity and access discipline prevents role collapse. A participant may be a sponsor in one context, provider in another, Stack Builder in another, and capital reader in another only where each role is separately recorded and access is limited to the recorded purpose.

26.2.1.3 Least privilege means that every participant receives only the minimum access necessary to perform the recorded role for the recorded time and purpose.

### 26.2.2 Access Control Requirements

26.2.2.1 Access controls should include identity verification appropriate to role, multi-factor authentication where appropriate, role-based access control, attribute-based access where needed, time-limited access, room-based access, system-based access, data-class-based access, approval workflows, access logging, periodic review, immediate revocation, and incident-triggered suspension.

26.2.2.2 Privileged access should be limited, monitored, logged, reviewed, and separated from ordinary participant access. Administrative access must not be granted by sponsorship, institutional seniority, media status, public authority status, capital-reader status, or personal relationship.

26.2.2.3 Shared accounts, unmanaged accounts, informal access, unlogged access, and access by implication are prohibited for controlled, restricted, sovereign, protected, cyber-sensitive, public authority-sensitive, capital-reader-room-only, insurance-reader-room-only, handoff-only, or legal-hold materials.

### 26.2.3 Access Records

26.2.3.1 Identity and Access Records should identify user, role, organization where applicable, access class, systems, rooms, datasets, repositories, dashboards, access duration, approval basis, access events, revocations, exceptions, incidents, and archive reference.

26.2.3.2 Access reviews should occur at defined gates, including onboarding, role change, room entry, data-room access, controlled evidence access, live validation start, incident occurrence, cycle close, and teardown.

### 26.2.4 Identity and Access Boundary

26.2.4.1 Access does not create ownership, publication permission, data-use permission, AI-use permission, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.2.4.2 Access permits only the recorded use.

## 26.3 Zero-Trust Controls

### 26.3.1 Zero-Trust Function

26.3.1.1 **Zero-Trust Controls** require Nexus Universe systems, rooms, repositories, dashboards, data rooms, Stack Workspaces, Nexus Core environments, Foundry workflows, BuildGrid workflows, telemetry systems, public authority learning surfaces, capital-reader rooms, insurance-readiness rooms, and handoff workflows to assume that trust must be continuously verified rather than granted by location, role label, network position, sponsorship, institutional prestige, or prior access.

26.3.1.2 Zero-trust discipline is necessary because Nexus Universe operates across distributed teams, host hubs, cloud systems, sovereign data zones, public dashboards, controlled rooms, sponsor-supported infrastructure, provider-supported infrastructure, public authority learning surfaces, and remote participants.

26.3.1.3 No participant, device, service, system, workload, model, data flow, API, dashboard, repository, or room should be trusted merely because it is inside a Nexus Universe environment.

### 26.3.2 Zero-Trust Requirements

26.3.2.1 Zero-trust controls should include continuous authentication, device posture review where appropriate, least privilege, network segmentation, service identity, workload identity, API authentication, conditional access, session logging, anomaly detection, data flow monitoring, secrets management, and rapid revocation.

26.3.2.2 Sensitive workflows should require additional verification, including controlled evidence access, restricted telemetry access, public authority-sensitive access, protected knowledge access, cyber range access, data-room access, AI system access, and handoff package access.

26.3.2.3 Zero-trust controls should apply to sponsor-provided infrastructure, provider systems, host systems, cloud environments, network environments, data rooms, and external tools integrated into Nexus Universe.

### 26.3.3 Zero-Trust Records

26.3.3.1 Zero-Trust Records should identify protected environment, identity controls, network controls, service controls, device controls, access policies, exceptions, monitoring status, incidents, corrections, and archive reference.

26.3.3.2 Exceptions to zero-trust controls must be risk-reviewed, time-limited, and documented.

### 26.3.4 Zero-Trust Boundary

26.3.4.1 Zero-trust controls within Nexus Universe do not create external cybersecurity certification, compliance approval, public authority approval, procurement status, insurance approval, deployment authorization, or execution authority.

26.3.4.2 Zero trust protects Nexus Universe operations only.

## 26.4 Secure Collaboration and Tooling

### 26.4.1 Secure Collaboration Function

26.4.1.1 **Secure Collaboration and Tooling** governs the digital tools used for Nexus Universe planning, Foundry work, BuildGrid coordination, code repositories, data review, model review, document drafting, evidence assembly, dashboard operations, public-safe reporting, room operations, incident response, correction, archive, and lawful handoff preparation.

26.4.1.2 Collaboration tools are part of the security surface. Uncontrolled chat, unmanaged file sharing, unapproved repositories, informal AI tools, personal storage, public links, unmanaged spreadsheets, and unlogged evidence sharing can compromise validity-by-record, data protection, protected knowledge, cyber security, public authority confidentiality, capital-reader confidentiality, and correctionability.

26.4.1.3 Secure collaboration must preserve both work speed and record integrity.

### 26.4.2 Tooling Requirements

26.4.2.1 Approved tooling should support identity control, access control, audit logs, version history, permission management, encryption where appropriate, retention rules, export controls, legal hold support, incident review, correction records, and archive integration.

26.4.2.2 Unapproved tools must not be used for restricted telemetry, controlled evidence, public authority-sensitive information, sovereign data, protected knowledge, personal data, cyber-sensitive information, capital-reader materials, insurance-reader materials, handoff packages, or legal-hold materials.

26.4.2.3 AI-enabled collaboration tools must be reviewed for data retention, training use, prompt logging, output control, protected knowledge exposure, public authority data exposure, and downstream reuse.

### 26.4.3 Collaboration Records

26.4.3.1 Secure Collaboration Records should identify approved tools, permitted uses, prohibited uses, access classes, data classes, retention rules, export rules, AI-use status, incident history, corrections, and archive reference.

26.4.3.2 Tool exceptions should be recorded and corrected or retired.

### 26.4.4 Tooling Boundary

26.4.4.1 Use of an approved tool does not create publication permission, external reliance, procurement status, financeability, insurance approval, public authority approval, deployment authorization, or execution authority.

26.4.4.2 Tools support recorded work; they do not create authority.

## 26.5 Controlled-Room Security

### 26.5.1 Controlled-Room Security Function

26.5.1.1 **Controlled-Room Security** governs security for controlled data rooms, sovereign data rooms, cyber range viewing rooms, public authority learning rooms, capital-reader rooms, insurance-readiness rooms, community safeguard rooms, expert rooms, team zones, Platform Control Room, Stewards Room, Records and Recognition Room, and any other physical, virtual, or hybrid environment with access restrictions.

26.5.1.2 Controlled rooms protect sensitive information, evidence integrity, role separation, confidentiality, public-safe classification, protected knowledge, public authority boundaries, capital-readiness boundaries, insurance-readiness boundaries, and lawful handoff boundaries.

26.5.1.3 A controlled room is secure only if access, conduct, recording, extraction, publication, output review, incident response, and correction are all governed.

### 26.5.2 Controlled-Room Requirements

26.5.2.1 Controlled-room security should include access verification, entry logs, role checks, device controls where appropriate, no-recording rules where applicable, screen controls, secure display rules, visitor escort rules where appropriate, confidentiality notices, output review, data extraction limits, incident reporting, and teardown procedures.

26.5.2.2 Virtual controlled rooms should include authenticated access, waiting-room controls where appropriate, participant verification, screen-sharing controls, recording restrictions, file-sharing controls, chat retention rules, watermarking where appropriate, and session logs.

26.5.2.3 Room security should be heightened for protected knowledge, youth data, public authority-sensitive materials, cyber-sensitive materials, sovereign data, capital-reader materials, insurance-reader materials, and handoff-only materials.

### 26.5.3 Controlled-Room Records

26.5.3.1 Controlled-Room Security Records should identify room identity, purpose, access list, access events, materials reviewed, device rules, recording permissions, outputs generated, incidents, corrections, and archive reference.

26.5.3.2 Room breaches must be recorded, contained, corrected, and linked to affected downstream records.

### 26.5.4 Controlled-Room Boundary

26.5.4.1 Controlled-room access does not create data ownership, publication permission, AI-use permission, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.5.4.2 Controlled rooms protect review; they do not authorize use beyond the room.

## 26.6 Cyber Range Security

### 26.6.1 Cyber Range Security Function

26.6.1.1 **Cyber Range Security** governs environments used for attack simulation, defense testing, recovery testing, identity and access testing, secrets and key-management testing, software supply-chain testing, incident reconstruction, cyber-physical scenarios, public authority learning, insurance-readiness evidence, and cyber recovery recognition.

26.6.1.2 Cyber ranges create special risk because they may involve exploit methods, vulnerabilities, simulated attacks, defensive weaknesses, system configurations, credentials, infrastructure patterns, and cyber-sensitive telemetry.

26.6.1.3 Cyber range security must ensure that learning and evidence do not become exposure, misuse, weaponization, public panic, public warning overclaim, or operational vulnerability.

### 26.6.2 Cyber Range Requirements

26.6.2.1 Cyber range environments should be isolated, access-controlled, monitored, logged, segmented, time-bounded, and configured to prevent spillover into production systems or external networks.

26.6.2.2 Cyber range materials must classify exploit details, vulnerability information, defensive configurations, system topology, telemetry, incident reconstructions, and public-safe summaries.

26.6.2.3 Cyber range publication must be reviewed to prevent exposure of actionable exploit details, sensitive defensive gaps, credentials, system identifiers, protected infrastructure information, or public authority-sensitive materials.

### 26.6.3 Cyber Range Records

26.6.3.1 Cyber Range Security Records should identify range environment, scenario, participants, access class, isolation controls, logs, outputs, vulnerabilities identified, correction actions, public-safe summaries, and archive reference.

26.6.3.2 Cyber range incidents must trigger containment, forensic review, correction, and archive update.

### 26.6.4 Cyber Range Boundary

26.6.4.1 Cyber Range Security does not create cybersecurity certification, public authority approval, procurement status, financeability, insurance approval, public warning, emergency command, deployment authorization, or execution authority.

26.6.4.2 Cyber range outputs are bounded evidence under controlled conditions only.

## 26.7 Foundry Security Controls

### 26.7.1 Foundry Security Function

26.7.1.1 **Foundry Security Controls** govern security for Nexus Foundry Programs, Tracks, Dockets, Quests, Bounties, Builds, review gates, release classes, public-good software preparation, data object preparation, model object preparation, evidence planning, Stack Passport preparation, Grid input preparation, Rails route preparation, and lawful handoff package preparation.

26.7.1.2 Foundry work is upstream but not low risk. Early-stage Dockets may contain sensitive public authority questions, community concerns, protected knowledge indicators, technical vulnerabilities, data needs, sovereign data issues, cyber issues, sponsor conflicts, capital-readiness gaps, and handoff dependencies.

26.7.1.3 Foundry security prevents preparation work from becoming an uncontrolled leakage surface.

### 26.7.2 Foundry Security Requirements

26.7.2.1 Foundry Security Controls should include Docket classification, access control, contributor role records, review-gate security, release-class security, repository security, dependency review, secrets management, data minimization, protected knowledge screening, public authority-sensitive screening, sponsor conflict review, and publication control.

26.7.2.2 Foundry outputs should not proceed to BuildGrid, Nexus Core, public dashboards, public-safe reports, Grid input, Rails routing, or handoff packages until security-relevant issues are classified and reviewed.

26.7.2.3 Sponsor-supported Foundry Programs require additional controls to prevent sponsor access to restricted work, sponsor control over Dockets, and sponsor-driven publication.

### 26.7.3 Foundry Security Records

26.7.3.1 Foundry Security Records should identify program, Docket, Track, Quest, Bounty, or Build; security classification; access list; protected knowledge status; data status; cyber status; public authority sensitivity; sponsor conflict status; correction status; and archive reference.

26.7.3.2 Foundry security issues may route work to correction, hold, controlled review, restricted release, or archive.

### 26.7.4 Foundry Security Boundary

26.7.4.1 Foundry Security Controls do not create validation, certification, procurement status, financeability, insurance approval, public authority approval, deployment authorization, or execution authority.

26.7.4.2 They secure preparation work only.

## 26.8 BuildGrid Security Controls

### 26.8.1 BuildGrid Security Function

26.8.1.1 **BuildGrid Security Controls** govern the distributed security of Nexus BuildGrid tasks, Quests, Bounties, Builds, code contributions, data contributions, model contributions, documentation, public-safe reporting components, benchmark tools, dashboard components, learning objects, Evidence Pack components, Grid components, Rails components, handoff components, maintainers, reviewers, and contributors.

26.8.1.2 BuildGrid’s distributed nature creates specific security risks: unreviewed code, malicious contributions, dependency vulnerabilities, secret leakage, unsafe data handling, hidden model substitutions, poisoned datasets, benchmark leakage, sponsor-directed manipulation, contributor identity issues, and uncontrolled publication.

26.8.1.3 BuildGrid security must make open participation compatible with evidence integrity.

### 26.8.2 BuildGrid Security Requirements

26.8.2.1 BuildGrid Security Controls should include contributor identity controls appropriate to work class, repository permissions, code review, dependency scanning, secret scanning, software bill of materials where appropriate, data review, model review, benchmark integrity controls, maintainer approval, release-class review, license review, public-safe review, and correction pathways.

26.8.2.2 High-risk BuildGrid work must not be accepted into Universe-ready, Grid-ready, Rails-ready, handoff-ready, public-good release, or public dashboard status without security review.

26.8.2.3 BuildGrid bounties involving cyber, AI, data, public authority materials, protected knowledge, public dashboards, or handoff packages require heightened controls.

### 26.8.3 BuildGrid Security Records

26.8.3.1 BuildGrid Security Records should identify work object, contributor, maintainer, reviewer, repository, dependency status, secret status, data status, model status, license status, release class, security issues, correction status, and archive reference.

26.8.3.2 Security rejected, corrected, superseded, or withdrawn work must remain traceable where relevant to downstream trust.

### 26.8.4 BuildGrid Security Boundary

26.8.4.1 BuildGrid Security Controls do not create software warranty, cybersecurity certification, procurement status, financeability, insurance approval, public authority approval, deployment authorization, or execution authority.

26.8.4.2 They secure distributed public-good work only.

## 26.9 Data Classification

### 26.9.1 Data Classification Function

26.9.1.1 **Data Classification** is the system for assigning data, evidence, telemetry, documents, dashboards, maps, models, prompts, logs, images, videos, public-safe reports, room records, Stack Passports, Evidence Packs, Grid inputs, Rails routes, and handoff packages to defined access and handling classes.

26.9.1.2 Data Classification is necessary because Nexus Universe handles data that may be public, public-safe, expert-visible, controlled, restricted, sovereign, protected, cyber-sensitive, public authority-sensitive, community-sensitive, youth-sensitive, privacy-sensitive, capital-reader-room-only, insurance-reader-room-only, handoff-only, legal-hold, archive-only, or prohibited for publication.

26.9.1.3 Classification controls use, access, AI handling, publication, dashboard display, transfer, retention, deletion, archive, and correction.

### 26.9.2 Classification Classes

26.9.2.1 Classification classes should include, at minimum, public, public-safe, expert-visible, controlled, restricted, sovereign, protected knowledge, personal data, rights-bearing data, youth-sensitive, cyber-sensitive, infrastructure-sensitive, public authority-sensitive, commercial-confidential, capital-reader-room-only, insurance-reader-room-only, handoff-only, legal-hold, and archive-only.

26.9.2.2 Classification should be assigned at intake and reviewed at each gate, including Foundry Docket creation, BuildGrid tasking, Stack Passport submission, Nexus Core integration, public dashboard review, Evidence Pack assembly, Grid input review, Rails routing, handoff preparation, publication, correction, and archive.

26.9.2.3 Where classification is uncertain, the more protective classification should apply until reviewed.

### 26.9.3 Classification Records

26.9.3.1 Data Classification Records should identify object, source, classification, steward, access rules, permitted uses, prohibited uses, publication status, AI-use status, transfer status, retention, correction status, and archive reference.

26.9.3.2 Reclassification must be recorded, including reason, effective date, downstream effects, and correction needs.

### 26.9.4 Data Classification Boundary

26.9.4.1 Data classification does not create data ownership, consent, publication permission, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.9.4.2 Classification governs handling only.

## 26.10 Privacy Baseline

### 26.10.1 Privacy Baseline Function

26.10.1.1 **Privacy Baseline** defines the minimum privacy protections required for personal data, rights-bearing data, youth data, participant data, community data, public authority participant data, media participant data, contributor records, learning records, access logs, telemetry that may identify persons, dashboard interactions, public learning feedback, and any data capable of identifying or affecting individuals.

26.10.1.2 Privacy is a public-good validity condition. A high-performing stack that misuses personal data, exposes individuals, enables re-identification, or converts participation into profiling undermines trust even if its technical performance is strong.

26.10.1.3 Privacy protections must apply across Foundry intake, BuildGrid participation, Nexus Core validation, data rooms, public dashboards, media coverage, public-safe reports, Grid inputs, Rails routes, handoff packages, retention, correction, and archive.

### 26.10.2 Privacy Requirements

26.10.2.1 The Privacy Baseline should include data minimization, purpose limitation, access control, consent or lawful basis review where applicable, privacy impact review where appropriate, youth safeguards, de-identification where appropriate, aggregation where appropriate, re-identification risk review, no-public-PII rules, output review, retention limitation, deletion rules, breach response, and correction.

26.10.2.2 Privacy-sensitive data must not be used for unrelated profiling, marketing, social scoring, public ranking, employment screening, insurance determination, investment decisions, procurement evaluation, public authority decision-making, or AI training without separate lawful basis and recorded permission.

26.10.2.3 Public dashboards and public-safe reports must avoid displaying identifiable information unless specifically approved, necessary, lawful, and public-safe.

### 26.10.3 Privacy Records

26.10.3.1 Privacy Records should identify data category, source, purpose, lawful basis or permission where applicable, access class, permitted use, prohibited use, retention, deletion, privacy review, incident status, correction status, and archive reference.

26.10.3.2 Privacy incidents must be linked to affected records and downstream outputs.

### 26.10.4 Privacy Baseline Boundary

26.10.4.1 Privacy Baseline compliance within Nexus Universe does not create external legal compliance approval, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.10.4.2 The Privacy Baseline protects personal and rights-bearing information within Nexus Universe only.

## 26.11 Rights-Bearing Data Handling

### 26.11.1 Rights-Bearing Data Function

26.11.1.1 **Rights-Bearing Data Handling** governs data that relates to individuals, communities, Indigenous peoples, protected groups, vulnerable populations, workers, patients, students, youth, residents, service users, affected stakeholders, or other persons or groups whose rights, interests, dignity, privacy, safety, livelihood, culture, or legal position may be affected by collection, processing, display, modeling, publication, or handoff.

26.11.1.2 Rights-bearing data must not be treated as ordinary technical input. It carries human, legal, ethical, social, cultural, and public-good obligations.

26.11.1.3 Rights-bearing data may appear in health analytics, public authority learning, community risk mapping, workforce records, youth participation, accessibility feedback, public learning, geospatial records, disaster risk data, public service data, cyber incident data, and capital-readiness or insurance-readiness materials.

### 26.11.2 Handling Requirements

26.11.2.1 Rights-bearing data handling should include purpose limitation, minimization, access control, consent or lawful basis review where applicable, human review, bias and harm review where appropriate, protected knowledge screening, geospatial risk screening, public-safe output review, AI-use restriction, downstream use restriction, correction rights where applicable, and archive controls.

26.11.2.2 Rights-bearing data must not be used to create social scoring, discriminatory profiling, employment exclusion, insurance discrimination, public authority adverse decisions, procurement exclusion, credit decisions, immigration consequences, policing consequences, or public shame by implication.

26.11.2.3 Where data relates to communities or Indigenous actors, consent and protected knowledge boundaries must be preserved.

### 26.11.3 Rights-Bearing Data Records

26.11.3.1 Rights-Bearing Data Records should identify data subject category, group sensitivity, source, permission or lawful basis where applicable, purpose, access class, AI-use status, publication status, downstream restrictions, correction pathway, retention, deletion, and archive reference.

26.11.3.2 Records should identify whether data is individual, household, community, group, Indigenous, youth, health-sensitive, public authority-sensitive, or otherwise rights-bearing.

### 26.11.4 Rights-Bearing Data Boundary

26.11.4.1 Rights-bearing data handling does not create consent, publication permission, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.11.4.2 It creates heightened stewardship obligations only.

## 26.12 No PII in Public Repositories, Open Releases, or Public Dashboards

### 26.12.1 No-PII Rule

26.12.1.1 **No PII in Public Repositories, Open Releases, or Public Dashboards** means that personally identifiable information, directly identifying participant data, youth data, private contact details, credentials, access logs, sensitive metadata, health-sensitive data, public authority participant details where restricted, community participant details where restricted, or any data reasonably capable of identifying a person must not be included in public repositories, open-source releases, public datasets, public dashboards, public media packages, or public archives unless a specific public-safe review, lawful basis, and recorded permission permit disclosure.

26.12.1.2 Public-good release is not a reason to expose personal data. Open technical baselines must remain open without making people open.

26.12.1.3 This rule applies to source code, issue trackers, commit histories, notebooks, logs, telemetry extracts, benchmark datasets, screenshots, dashboards, documentation, video, transcripts, public-safe reports, data products, and archive materials.

### 26.12.2 PII Prevention Requirements

26.12.2.1 Public release workflows must include PII screening, secret scanning, metadata review, screenshot review, log review, sample data review, dataset review, model card review, public dashboard review, and archive review.

26.12.2.2 Synthetic data, anonymized data, aggregated data, or public-safe derivative data should be used where public release requires examples, testing, dashboards, or reproducibility.

26.12.2.3 If PII is discovered in public materials, immediate containment, removal, correction, notification review, and archive update should occur.

### 26.12.3 No-PII Records

26.12.3.1 No-PII Review Records should identify public release object, screening method, reviewer, findings, correction actions, approval status, and archive reference.

26.12.3.2 PII incidents must be recorded and linked to affected public outputs.

### 26.12.4 No-PII Boundary

26.12.4.1 Removal of PII does not automatically make data public-safe, publishable, AI-trainable, or handoff-ready.

26.12.4.2 PII removal is one requirement, not the entire public-safe review.

## 26.13 Sovereign Data Zones

### 26.13.1 Sovereign Data Zone Function

26.13.1.1 **Sovereign Data Zones** are jurisdictional, institutional, public authority, Indigenous, community, contractual, or steward-defined data environments within which data must remain subject to specific residency, localization, access, processing, transfer, publication, AI-use, output review, retention, and archive controls.

26.13.1.2 Sovereign Data Zones allow Nexus Universe to support national ownership, public authority learning, protected knowledge safeguards, community data stewardship, Indigenous data governance where applicable, and lawful continuation without uncontrolled extraction or cross-border transfer.

26.13.1.3 Sovereign Data Zones are not symbolic labels. They define binding handling requirements within Nexus Universe.

### 26.13.2 Zone Requirements

26.13.2.1 Sovereign Data Zones should identify data steward, jurisdiction, applicable restrictions, allowed processing locations, prohibited transfers, approved users, compute-to-data requirements, output review, public-safe summary rules, AI-use restrictions, retention, deletion, incident handling, correction, and archive.

26.13.2.2 Data from a Sovereign Data Zone must not be copied into general repositories, public dashboards, public reports, AI tools, cross-border storage, sponsor systems, provider systems, or handoff packages unless permitted by recorded zone rules.

26.13.2.3 Outputs derived from sovereign data must preserve downstream restrictions.

### 26.13.3 Zone Records

26.13.3.1 Sovereign Data Zone Records should identify zone scope, steward, data classes, access rules, localization rules, transfer controls, processing controls, output review, incidents, corrections, and archive reference.

26.13.3.2 Zone exceptions must be recorded and reviewed.

### 26.13.4 Sovereign Data Zone Boundary

26.13.4.1 Sovereign Data Zone status does not create public release permission, data ownership transfer, cross-border transfer permission, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.13.4.2 It defines data handling obligations only.

## 26.14 Localization Requirements

### 26.14.1 Localization Function

26.14.1.1 **Localization Requirements** define where certain data, systems, processing, storage, backup, logs, models, evidence, telemetry, dashboards, data rooms, public authority learning materials, protected knowledge, or handoff materials must physically or logically remain.

26.14.1.2 Localization requirements may arise from law, public authority conditions, data steward restrictions, Indigenous or community protocols, contracts, institutional policy, national ownership, security needs, privacy needs, protected knowledge safeguards, or public-good design choices.

26.14.1.3 Localization is a trust and sovereignty control. It must be implemented through architecture, not merely stated in policy.

### 26.14.2 Localization Controls

26.14.2.1 Localization controls should include approved storage locations, approved processing locations, approved backup locations, approved compute environments, prohibited export locations, cross-border transfer review, remote access controls, logging, output review, and deletion rules.

26.14.2.2 Cloud, compute, data-room, dashboard, AI, and collaboration tools must be reviewed for localization compatibility before use with localized data.

26.14.2.3 Public-safe summaries derived from localized data must be reviewed to ensure they do not defeat localization through indirect disclosure.

### 26.14.3 Localization Records

26.14.3.1 Localization Records should identify data or system, location requirement, steward, approved environments, transfer restrictions, remote access conditions, exception status, correction status, and archive reference.

26.14.3.2 Localization violations must be treated as data incidents and corrected.

### 26.14.4 Localization Boundary

26.14.4.1 Localization compliance does not create legal compliance approval, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.14.4.2 Localization governs where data and systems may reside and operate.

## 26.15 Compute-to-Data Default

### 26.15.1 Compute-to-Data Function

26.15.1.1 **Compute-to-Data Default** means that, for restricted, sovereign-sensitive, public authority-sensitive, rights-bearing, community-protected, Indigenous-protocol-governed, protected knowledge, health-sensitive, cyber-sensitive, infrastructure-sensitive, or high-risk datasets, Nexus Universe should prefer bringing approved computation to the data rather than exporting raw data to external systems or participants.

26.15.1.2 Compute-to-data preserves evidence generation while reducing data extraction risk, cross-border transfer risk, privacy risk, protected knowledge exposure, public authority confidentiality risk, and sponsor or provider data access risk.

26.15.1.3 Compute-to-data is a core Nexus Universe mechanism for reconciling high-performance validation with data sovereignty and public-good safeguards.

### 26.15.2 Compute-to-Data Requirements

26.15.2.1 Compute-to-data environments should define approved workloads, approved users, approved tools, approved models, output review, no-download rules, logging, monitoring, access controls, key management, retention, deletion, and correction pathways.

26.15.2.2 AI workflows in compute-to-data environments require additional controls for prompt logging, model access, retrieval restrictions, output review, protected knowledge screening, and training-use prohibition unless expressly permitted.

26.15.2.3 Outputs must be reviewed before inclusion in Evidence Packs, dashboards, public-safe reports, Grid inputs, Rails routes, or handoff packages.

### 26.15.3 Compute-to-Data Records

26.15.3.1 Compute-to-Data Records should identify dataset, steward, environment, workload, users, tools, model use, outputs, output review, incidents, corrections, and archive reference.

26.15.3.2 Records should preserve computational provenance without exposing raw data.

### 26.15.4 Compute-to-Data Boundary

26.15.4.1 Compute-to-data access does not create raw data access, publication permission, AI training permission, cross-border transfer permission, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.15.4.2 It permits bounded computation only.

## 26.16 Cross-Border Transfer Controls

### 26.16.1 Cross-Border Transfer Function

26.16.1.1 **Cross-Border Transfer Controls** govern the movement, access, replication, remote processing, publication, export, backup, model ingestion, dashboard display, handoff, or derivative transfer of data, evidence, telemetry, protected knowledge, public authority-sensitive material, sovereign data, personal data, cyber-sensitive material, or restricted records across national, jurisdictional, institutional, cloud-region, community, Indigenous, contractual, or steward-defined boundaries.

26.16.1.2 Cross-border transfer risk can arise even when data is not downloaded, including through remote access, screenshots, model prompts, embeddings, logs, API calls, support access, cloud replication, backup, public dashboards, or AI summarization.

26.16.1.3 Nexus Universe must treat cross-border transfer as a governance event, not a technical convenience.

### 26.16.2 Transfer Requirements

26.16.2.1 Cross-border transfers should require classification review, data steward approval where applicable, legal or policy review where applicable, public authority condition review, protected knowledge review, privacy review, cybersecurity review, localization review, output review, and downstream restriction recording.

26.16.2.2 Transfers must identify source jurisdiction, destination jurisdiction, data class, purpose, duration, access controls, storage location, processing location, deletion plan, retention, permitted uses, prohibited uses, and correction pathway.

26.16.2.3 Where transfer is not permitted, compute-to-data, public-safe summaries, synthetic data, aggregated outputs, or localized review should be used.

### 26.16.3 Transfer Records

26.16.3.1 Cross-Border Transfer Records should identify transferred object, source, destination, steward, approval basis, restrictions, access class, transfer method, retention, deletion, incident status, correction status, and archive reference.

26.16.3.2 Unauthorized transfer must trigger containment, access review, notification review where applicable, correction, and archive update.

### 26.16.4 Transfer Boundary

26.16.4.1 Cross-border transfer approval for one purpose does not create publication permission, AI-use permission, public release permission, handoff permission, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.16.4.2 Transfer is purpose-specific and correctionable.

## 26.17 Protected Knowledge Controls

### 26.17.1 Protected Knowledge Control Function

26.17.1.1 **Protected Knowledge Controls** govern identification, classification, access, use, AI handling, publication, mapping, dashboard display, reporting, handoff, correction, and archive treatment of protected knowledge within Nexus Universe.

26.17.1.2 Protected knowledge may include Indigenous knowledge, traditional ecological knowledge, sacred or culturally restricted information, community risk knowledge, sensitive location knowledge, ecological sensitivity, vulnerability information, health-sensitive community context, infrastructure-sensitive community context, or information shared under trust, protocol, or restriction.

26.17.1.3 Protected knowledge must be protected even when it improves a model, map, report, dashboard, digital twin, benchmark, public-safe story, or handoff package.

### 26.17.2 Control Requirements

26.17.2.1 Protected Knowledge Controls should include early screening, protective classification, need-to-know access, community or protocol review where applicable, AI-use restriction, training-use prohibition unless expressly permitted, geospatial masking, publication review, output review, downstream restriction preservation, correction pathway, and archive controls.

26.17.2.2 Protected knowledge must not be placed in public repositories, public dashboards, open releases, public reports, media packages, prompts, embeddings, vector stores, or training datasets without specific recorded permission and safeguard review.

26.17.2.3 Where uncertainty exists, information should be treated as potentially protected until reviewed.

### 26.17.3 Protected Knowledge Records

26.17.3.1 Protected Knowledge Control Records should identify knowledge category, source context, permission status, access class, prohibited uses, approved uses if any, AI-use status, publication status, geospatial treatment, downstream restrictions, correction status, and archive reference.

26.17.3.2 Records should avoid exposing the protected content itself in public-safe form.

### 26.17.4 Protected Knowledge Boundary

26.17.4.1 Protected Knowledge Controls do not create consent, publication permission, AI-use permission, community approval, Indigenous consent, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.17.4.2 They preserve safeguard obligations.

## 26.18 Synthetic Data and Public-Safe Data

### 26.18.1 Synthetic and Public-Safe Data Function

26.18.1.1 **Synthetic Data and Public-Safe Data** are data approaches used to support testing, public dashboards, public learning, benchmark development, reproducibility, training exercises, public-good software, open releases, demonstrations, and public-safe reporting without exposing restricted, personal, sovereign, protected, cyber-sensitive, public authority-sensitive, or commercial-confidential data.

26.18.1.2 Synthetic data can reduce risk but does not automatically eliminate risk. Public-safe data can improve openness but must remain tied to review, provenance, limitations, and re-identification controls.

26.18.1.3 Synthetic and public-safe data must be fit for purpose and clearly labeled.

### 26.18.2 Data Requirements

26.18.2.1 Synthetic data should identify generation method, intended use, limitations, similarity risk, re-identification risk, bias risk, benchmark limitations, and prohibited uses.

26.18.2.2 Public-safe data should identify source, transformation method, aggregation, masking, removed fields, remaining risks, permitted use, prohibited use, correction status, and archive reference.

26.18.2.3 Synthetic or public-safe data must not be represented as real operational data unless clearly labeled and justified.

### 26.18.3 Data Records

26.18.3.1 Synthetic Data and Public-Safe Data Records should identify data object, source relationship, generation or transformation method, review status, use class, limitation, re-identification review, public-safe approval, correction status, and archive reference.

26.18.3.2 Corrections must occur if synthetic data is misleading, unsafe, biased, re-identifiable, or misused.

### 26.18.4 Synthetic and Public-Safe Data Boundary

26.18.4.1 Synthetic or public-safe status does not create certification, external legal compliance approval, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.18.4.2 It permits bounded use within the recorded purpose only.

## 26.19 Metadata and Re-Identification Risk

### 26.19.1 Metadata and Re-Identification Function

26.19.1.1 **Metadata and Re-Identification Risk** governs the risk that data thought to be safe may reveal individuals, communities, protected knowledge, sensitive locations, infrastructure details, public authority-sensitive facts, cyber-sensitive configurations, or commercial-confidential information through metadata, linkage, inference, aggregation, timestamps, geospatial signals, logs, filenames, device identifiers, model outputs, or dashboard interactions.

26.19.1.2 Re-identification risk is especially important in public dashboards, open releases, public-good datasets, public-safe reports, maps, digital twins, telemetry summaries, youth participation records, community data, health-sensitive data, and public authority learning materials.

26.19.1.3 Metadata can expose what the main content hides. Nexus Universe must review both.

### 26.19.2 Risk Controls

26.19.2.1 Controls should include metadata stripping, aggregation, masking, generalization, timestamp adjustment where appropriate, location blurring, small-cell suppression, output review, screenshot review, file property review, log review, prompt review, and model-output review.

26.19.2.2 Public release review must consider linkage risk, mosaic effect, sensitive location inference, community identification, youth identification, public authority identification, infrastructure identification, and protected knowledge inference.

26.19.2.3 AI systems must be reviewed for inferential reconstruction and memorization risk where relevant.

### 26.19.3 Risk Records

26.19.3.1 Metadata and Re-Identification Risk Records should identify object, risk type, review method, mitigation, residual risk, approval status, correction status, and archive reference.

26.19.3.2 Re-identification incidents must trigger containment, correction, public-safe notice where appropriate, and downstream review.

### 26.19.4 Re-Identification Boundary

26.19.4.1 Re-identification review does not guarantee anonymity, legal compliance, publication approval, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.19.4.2 It reduces and records risk within a defined context.

## 26.20 Logging and Monitoring

### 26.20.1 Logging and Monitoring Function

26.20.1.1 **Logging and Monitoring** governs the recording and observation of access events, system events, telemetry events, security events, data-room events, controlled-room events, repository events, model-use events, AI tool-use events, dashboard events, evidence-transfer events, Platform Control events, incident events, correction events, and archive events.

26.20.1.2 Logging and monitoring are required for validity-by-record, security, privacy, incident response, evidence custody, correctionability, access control, and public trust.

26.20.1.3 Logs are evidence-bearing objects and must be classified, protected, retained, corrected, and archived according to their sensitivity.

### 26.20.2 Logging Requirements

26.20.2.1 Logs should capture who accessed what, when, from where where appropriate, for what purpose where available, what action occurred, what output was created, what data was extracted, what model or tool was used, what intervention occurred, what correction occurred, and what downstream record was affected.

26.20.2.2 Logging should be proportionate and privacy-aware. Nexus Universe should not create excessive surveillance of participants, youth, communities, public learners, or public-interest actors.

26.20.2.3 Logs should be protected from tampering, unauthorized access, unauthorized deletion, and improper publication.

### 26.20.3 Monitoring Records

26.20.3.1 Logging and Monitoring Records should identify monitored system, log type, retention period, access class, review process, alerts, incidents, corrections, and archive reference.

26.20.3.2 Monitoring findings may support Platform Control, Stewards review, incident response, Evidence Pack assembly, score review, and correction.

### 26.20.4 Logging Boundary

26.20.4.1 Logs do not create public authority approval, certification, procurement status, financeability, insurance approval, public warning, deployment authorization, or execution authority.

26.20.4.2 Logs support evidence, security, and correction only.

## 26.21 Security Telemetry

### 26.21.1 Security Telemetry Function

26.21.1.1 **Security Telemetry** means security-relevant signals, events, logs, alerts, traces, vulnerability indicators, access anomalies, network events, endpoint events, identity events, repository events, data-room events, AI-use events, cyber range events, and incident indicators collected to protect Nexus Universe systems and evidence.

26.21.1.2 Security telemetry is different from public performance telemetry. It may reveal vulnerabilities, system topology, access patterns, defensive posture, public authority-sensitive information, cyber-sensitive conditions, protected knowledge indicators, personal data, or operational weaknesses.

26.21.1.3 Security telemetry must be protected while remaining available for incident response, evidence integrity, and correction.

### 26.21.2 Security Telemetry Requirements

26.21.2.1 Security telemetry should be collected for critical systems, controlled rooms, restricted dashboards, data rooms, repositories, AI workflows, public dashboards, Nexus Core environments, BuildGrid repositories, Foundry workflows, and handoff package workflows.

26.21.2.2 Security telemetry should support anomaly detection, incident response, access review, forensic analysis, breach notification review, and recurrence prevention.

26.21.2.3 Security telemetry must not be used for unrelated participant profiling, sponsor advantage, provider advantage, public authority overclaim, capital-readiness overclaim, media narratives, or public shaming.

### 26.21.3 Security Telemetry Records

26.21.3.1 Security Telemetry Records should identify telemetry source, classification, access class, retention, monitoring rules, alerts, incidents, corrections, and archive reference.

26.21.3.2 Security telemetry used in public-safe reports must be transformed and reviewed to prevent sensitive disclosure.

### 26.21.4 Security Telemetry Boundary

26.21.4.1 Security telemetry does not create security certification, public authority approval, procurement status, financeability, insurance approval, public warning, deployment authorization, or execution authority.

26.21.4.2 It protects Nexus Universe systems and records only.

## 26.22 Incident Response

### 26.22.1 Incident Response Function

26.22.1.1 **Incident Response** governs how Nexus Universe identifies, classifies, contains, investigates, corrects, communicates, escalates, records, and archives security, privacy, data, cyber, protected knowledge, public-safe reporting, public authority boundary, capital-readiness boundary, community safeguard, controlled-room, dashboard, repository, AI, telemetry, and handoff incidents.

26.22.1.2 Incident response is a core trust function. Nexus Universe cannot maintain evidence integrity unless incidents are treated as record events requiring containment and correction.

26.22.1.3 Incident response must be fast, proportionate, public-safe, legally aware, privacy-aware, safeguard-aware, and correctionable.

### 26.22.2 Response Phases

26.22.2.1 Incident response should include intake, triage, severity classification, containment, evidence preservation, access review, impact assessment, legal or notification review where applicable, public-safe communication review, correction planning, remediation, downstream dependency review, recurrence prevention, closure, and archive.

26.22.2.2 Incidents affecting public dashboards, recognition, scores, Grid inputs, Rails routes, handoff packages, public authority learning, capital-readiness materials, insurance-readiness materials, community safeguards, or protected knowledge require downstream record review.

26.22.2.3 Incidents may require escalation to Platform Control, Stewards Room, Incident Review Board, public authority contact, legal review, security response team, privacy review, protected knowledge review, or community safeguard review.

### 26.22.3 Incident Records

26.22.3.1 Incident Response Records should identify incident class, affected systems, affected records, affected participants, severity, containment actions, evidence preserved, corrections made, notices issued, downstream effects, recurrence prevention, closure status, and archive reference.

26.22.3.2 Incident records may be public-safe, controlled, restricted, protected, confidential, legal-hold, or archive-only.

### 26.22.4 Incident Response Boundary

26.22.4.1 Incident Response does not create external legal findings, regulatory findings, public authority decisions, procurement decisions, finance decisions, insurance decisions, public warnings, emergency commands, deployment authorizations, or execution authority.

26.22.4.2 It preserves and corrects Nexus Universe records and operations.

## 26.23 Breach Notification Where Applicable

### 26.23.1 Breach Notification Function

26.23.1.1 **Breach Notification Where Applicable** governs how Nexus Universe evaluates whether a security, privacy, data, protected knowledge, public authority-sensitive, sovereign data, youth data, cyber, controlled-room, or repository incident requires notification to affected persons, data stewards, public authorities, institutional partners, community actors, Indigenous governance actors where applicable, sponsors, providers, insurers, capital readers, hosts, or other lawful actors.

26.23.1.2 Notification obligations may arise from law, contract, data-sharing agreement, public authority condition, community protocol, Indigenous protocol, institutional policy, ethical obligation, or public-good safeguard rule.

26.23.1.3 Breach notification must be accurate, timely where required, public-safe, and careful not to expose additional sensitive information.

### 26.23.2 Notification Review

26.23.2.1 Notification review should identify incident type, affected data, affected persons or actors, jurisdiction, data steward, legal obligations, contractual obligations, community or Indigenous protocol obligations, public authority obligations, timing requirements, content requirements, and public-safe communication requirements.

26.23.2.2 Notifications should distinguish confirmed facts, suspected facts, actions taken, recommended protective measures where appropriate, contact point, and correction status.

26.23.2.3 Public notifications should avoid disclosing restricted telemetry, vulnerabilities, protected knowledge, sensitive locations, personal details beyond necessity, or unverified allegations.

### 26.23.3 Notification Records

26.23.3.1 Breach Notification Records should identify notification decision, basis, recipients, timing, content, delivery method, public-safe status, legal review status, correction status, and archive reference.

26.23.3.2 Decisions not to notify should also be recorded where a notification review occurred.

### 26.23.4 Notification Boundary

26.23.4.1 Breach Notification does not create legal admission, regulatory finding, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority unless a competent external process separately creates that status.

26.23.4.2 Notification communicates incident status and response only.

## 26.24 Secure Teardown and Data Deletion

### 26.24.1 Secure Teardown Function

26.24.1.1 **Secure Teardown and Data Deletion** governs the controlled shutdown, dismantling, deprovisioning, sanitization, deletion, return, archiving, or transition of Nexus Universe systems, rooms, environments, datasets, credentials, devices, cloud resources, compute resources, network resources, model environments, data rooms, dashboards, repositories, logs, temporary files, and controlled workspaces after use.

26.24.1.2 Secure teardown is essential because the live validation cycle may create temporary environments, temporary access, temporary datasets, temporary credentials, temporary dashboards, temporary telemetry stores, temporary AI workflows, and temporary public-safe materials that should not remain open, exposed, or uncontrolled after the cycle.

26.24.1.3 Teardown must preserve records required for validity, correction, auditability, legal hold, public-safe archive, Grid inputs, Rails routes, and lawful handoff while deleting or restricting material that should not persist.

### 26.24.2 Teardown Requirements

26.24.2.1 Secure teardown should include access revocation, credential rotation, secrets deletion or rotation, cloud resource shutdown, storage review, log preservation where required, temporary data deletion, device sanitization, repository permission review, room closure, dashboard status update, public-safe archive update, and legal hold review.

26.24.2.2 Data deletion must follow classification, retention, data steward instructions, localization rules, legal hold, public authority conditions, community or Indigenous protocols where applicable, and archive rules.

26.24.2.3 Handoff packages must not include temporary data, raw restricted data, secrets, or unreviewed logs by accident.

### 26.24.3 Teardown Records

26.24.3.1 Secure Teardown and Data Deletion Records should identify system or data object, teardown action, deletion action, retained records, legal hold status, archive status, responsible actor, verification method, exceptions, corrections, and archive reference.

26.24.3.2 Failed teardown must be treated as an incident where risk is material.

### 26.24.4 Teardown Boundary

26.24.4.1 Data deletion or teardown does not erase required correction history, legal hold obligations, archive obligations, or public-safe record obligations where retention is required.

26.24.4.2 Teardown closes temporary capability; it does not alter the validity of preserved records.

## 26.25 Data Retention and Archive

### 26.25.1 Retention and Archive Function

26.25.1.1 **Data Retention and Archive** governs how Nexus Universe retains, stores, protects, corrects, limits, deletes, archives, or restricts data, evidence, telemetry, logs, records, dashboards, cards, profiles, public-safe reports, room records, incident records, Stack Passports, Evidence Packs, Grid inputs, Rails routes, handoff packages, public archive materials, and controlled archive materials.

26.25.1.2 Retention preserves institutional memory, validity-by-record, correctionability, reproducibility, public trust, legal hold, and lawful handoff traceability. Over-retention can create privacy, security, protected knowledge, public authority, and cyber risk.

26.25.1.3 The retention system must balance memory and minimization.

### 26.25.2 Retention Requirements

26.25.2.1 Retention periods should be assigned by record class, data classification, legal hold status, public archive value, evidence value, correction value, public authority sensitivity, privacy sensitivity, protected knowledge status, cyber sensitivity, public-safe status, and handoff relevance.

26.25.2.2 Public archive materials should remain accessible where public-safe and not withdrawn. Controlled records should remain available only to authorized users. Restricted, protected, sovereign, legal-hold, and handoff-only records require stricter access.

26.25.2.3 Retention schedules must support correction, supersession, withdrawal, retirement, and archive annotation rather than silent deletion of material public records.

### 26.25.3 Retention Records

26.25.3.1 Data Retention and Archive Records should identify object, classification, retention period, archive class, deletion date where applicable, legal hold status, access class, correction status, supersession status, withdrawal status, and archive reference.

26.25.3.2 Retention exceptions and deletions must be recorded.

### 26.25.4 Retention Boundary

26.25.4.1 Retention does not create publication permission, data-use permission, AI-use permission, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

26.25.4.2 Retention preserves records only for the recorded purpose.

## 26.26 Privacy, Security, and Data Incidents

### 26.26.1 Incident Function

26.26.1.1 **Privacy, Security, and Data Incidents** are events that compromise, threaten, expose, misuse, misclassify, improperly access, improperly transfer, improperly publish, improperly delete, improperly retain, or improperly process Nexus Universe systems, data, evidence, telemetry, personal data, rights-bearing data, sovereign data, protected knowledge, cyber-sensitive information, public authority-sensitive information, capital-reader materials, insurance-reader materials, controlled-room content, public dashboards, repositories, AI workflows, or handoff packages.

26.26.1.2 These incidents must be treated as record integrity issues as well as operational issues. A data incident can affect evidence, scoring, recognition, Grid inputs, Rails routes, public-safe reports, public authority learning, capital-readiness, insurance-readiness, community safeguards, and lawful handoff.

26.26.1.3 Privacy, security, and data incidents may arise from human error, tool failure, malicious action, misclassification, sponsor misuse, provider misuse, public authority boundary confusion, AI misuse, uncontrolled publication, cross-border transfer, uncontrolled extraction, public dashboard error, or archive error.

### 26.26.2 Incident Classes

26.26.2.1 Incident classes may include unauthorized access, credential compromise, secret exposure, repository exposure, public dashboard exposure, PII exposure, rights-bearing data misuse, youth data exposure, sovereign data transfer, localization violation, protected knowledge exposure, AI-use violation, training-use violation, cyber-sensitive exposure, public authority-sensitive exposure, capital-reader room breach, insurance-reader room breach, controlled-room breach, data extraction breach, metadata exposure, re-identification incident, deletion failure, retention failure, and archive breach.

26.26.2.2 Severity should consider sensitivity, scale, reversibility, public exposure, affected persons, affected communities, public authority involvement, protected knowledge status, cyber implications, legal obligations, downstream dependency effects, and recurrence risk.

26.26.2.3 Incidents may require immediate Platform Control action, access suspension, dashboard hold, score hold, recognition hold, Grid hold, Rails hold, handoff hold, or public-safe notice.

### 26.26.3 Incident Records

26.26.3.1 Privacy, Security, and Data Incident Records should identify incident class, affected data or system, affected records, access class, severity, containment action, notification review, correction action, downstream effects, recurrence prevention, closure status, legal hold status, and archive reference.

26.26.3.2 Records may be public-safe, controlled, restricted, protected, confidential, legal-hold, or archive-only.

### 26.26.4 Incident Boundary

26.26.4.1 Privacy, Security, and Data Incident Records do not create external legal findings, regulatory findings, public authority decisions, procurement decisions, finance decisions, insurance decisions, deployment authorizations, or execution authority.

26.26.4.2 They document and correct Nexus Universe incidents.

## 26.27 Correction, Containment, and Public-Safe Notice

### 26.27.1 Correction and Containment Function

26.27.1.1 **Correction, Containment, and Public-Safe Notice** governs the final response discipline for security, privacy, data, protected knowledge, public authority-sensitive, cyber-sensitive, controlled-room, dashboard, repository, AI-use, telemetry, retention, deletion, and archive incidents affecting Nexus Universe.

26.27.1.2 Containment stops harm from spreading. Correction repairs the record and affected systems. Public-safe notice preserves trust where public-facing or affected-party communication is required or appropriate.

26.27.1.3 This function operationalizes the Correctionability Doctrine within the security, privacy, and data domain.

### 26.27.2 Containment Actions

26.27.2.1 Containment actions may include access revocation, credential rotation, session termination, dashboard suspension, repository takedown, data-room lock, download disablement, public archive hold, AI workflow suspension, model index quarantine, network isolation, stack quarantine, evidence hold, score hold, recognition hold, Grid hold, Rails hold, handoff hold, publication withdrawal, and legal hold.

26.27.2.2 Containment should be proportionate to risk and must be recorded.

26.27.2.3 Where containment affects public-facing materials, a public-safe status notice should be considered.

### 26.27.3 Correction Actions

26.27.3.1 Correction actions may include data deletion where lawful and appropriate, metadata removal, geospatial masking, PII removal, protected knowledge restriction, public-safe wording correction, dashboard correction, report correction, media correction, archive annotation, Evidence Pack correction, Stack Passport correction, telemetry correction, score correction, recognition correction, Grid input correction, Rails route correction, handoff package correction, and recurrence prevention.

26.27.3.2 Corrections must identify affected downstream records and ensure that outdated materials are corrected, superseded, withdrawn, retired, or archived as appropriate.

26.27.3.3 Correction should avoid creating additional exposure. Where public detail would worsen harm, controlled correction and public-safe notice should be used.

### 26.27.4 Public-Safe Notice

26.27.4.1 Public-Safe Notices should identify that an issue occurred, the public-facing status affected, what has changed, what users should not infer, where authoritative status appears, and whether further updates are expected.

26.27.4.2 Public-Safe Notices must not disclose restricted telemetry, vulnerabilities, protected knowledge, personal data, public authority-sensitive information, cyber-sensitive details, confidential sponsor or provider information, capital-reader materials, insurance-reader materials, or handoff-only details.

26.27.4.3 Public-Safe Notices should be accessible, plain-language where appropriate, timestamped, versioned, and linked to corrected public records.

### 26.27.5 Final Security, Privacy, and Data Rule

26.27.5.1 No security, privacy, data, protected knowledge, cyber, public authority-sensitive, capital-reader, insurance-reader, community safeguard, or controlled-room incident may be hidden where it materially affects the public-safe record, validation integrity, affected-party rights, public authority boundaries, Grid inputs, Rails routes, handoff packages, or archive integrity.

26.27.5.2 The final rule is that Nexus Universe secures before it validates; minimizes before it publishes; computes to data before it exports; protects knowledge before it visualizes; corrects before it continues; and preserves public trust by making every material security, privacy, and data failure containable, recordable, correctable, and public-safe where notice is required.
