# XXVIII. COMMONS

### Summary

* Defines the public-good technical baseline for reusable digital infrastructure across Nexus Universe.
* Governs open assets, software, data, models, schemas, APIs, dashboards, learning objects, and release packages.
* Sets controls for licensing, security, contributors, dependencies, public release, correction, deprecation, and archive.

## 28.1 Public-Good Technical Baseline

### 28.1.1 Public-Good Technical Baseline Function

28.1.1.1 **Public-Good Technical Baseline** means the reusable technical foundation produced, maintained, released, corrected, and archived through Nexus Universe, Nexus Foundry, BuildGrid, Nexus Core, Nexus Grid, Nexus Rails, Nexus Academy, Nexus Observatory, Nexus Studio, Nexus Registry, Nexus Marketplace, and Nexus Reports for public-good use across countries, sectors, technologies, hazards, and lawful continuation pathways.

28.1.1.2 The Public-Good Technical Baseline is the technical memory of Nexus Universe. It captures reusable methods, software, data structures, model documentation, APIs, schemas, benchmark tools, dashboards, learning objects, public-safe reports, reference implementations, release packages, Stack Passport components, Evidence Pack templates, Grid input formats, Rails routing templates, and handoff dependency structures so that each annual cycle does not disappear into spectacle or isolated demonstration.

28.1.1.3 The Public-Good Technical Baseline exists to make high-performance stack validation reusable, inspectable, interoperable, corrigible, teachable, and nationally extensible. It does not create certification, standards conformance, procurement status, public authority approval, financeability, insurance approval, deployment authorization, or execution authority.

### 28.1.2 Baseline Composition

28.1.2.1 The Public-Good Technical Baseline may include open technical assets, public-good software, reference implementations, benchmark harnesses, data schemas, model cards, system cards, benchmark cards, safety-case templates, cyber-case templates, data-case templates, interoperability profiles, telemetry record formats, proof receipt structures, public dashboard components, learning modules, repository structures, release-class rules, and correction templates.

28.1.2.2 Baseline materials may be public, public-safe, expert-visible, controlled, restricted, sovereign, protected, national, handoff-only, or archive-only depending on their sensitivity, rights status, security posture, public-good purpose, and lawful-use conditions.

28.1.2.3 Baseline inclusion requires versioning, provenance, license status, dependency review, security review, public-safe review where applicable, maintainer assignment where required, correction pathway, and archive reference.

### 28.1.3 Baseline Records

28.1.3.1 Public-Good Technical Baseline Records should identify the object, source, Foundry origin, BuildGrid origin, Nexus Core validation relationship, release class, maintainer, license, dependencies, security status, public-safe status, correction status, deprecation status, archive status, and downstream use restrictions.

28.1.3.2 Baseline Records should distinguish reusable public-good assets from controlled assets, restricted assets, proprietary contributions, sponsor-supported assets, provider-contributed assets, public authority-sensitive assets, community-protected assets, and handoff-only materials.

### 28.1.4 Baseline Boundary

28.1.4.1 Public-Good Technical Baseline status does not create warranty, certification, standards conformance, procurement approval, public authority approval, financeability, insurance approval, deployment authorization, or execution authority.

28.1.4.2 The Public-Good Technical Baseline provides reusable technical memory and public-good infrastructure only.

## 28.2 Open Technical Assets

### 28.2.1 Open Technical Asset Function

28.2.1.1 **Open Technical Assets** are technical objects released for public-good reuse under approved open, public-good, or otherwise permissible licenses and governance conditions.

28.2.1.2 Open Technical Assets allow Nexus Universe outputs to be reused beyond a single validation cycle while preserving security, privacy, protected knowledge, public authority boundaries, sponsor boundaries, and correctionability.

28.2.1.3 Openness is not automatic. A technical object becomes open only after release review confirms that it is suitable for public release, appropriately licensed, sufficiently documented, secure enough for its release class, free from prohibited personal data, free from protected knowledge exposure, and bounded by correct public-use notices.

### 28.2.2 Open Asset Requirements

28.15.1.2 Digital object readiness helps distinguish early concepts, prototypes, tested components, integrated systems, validated stacks, public-good releases, controlled releases, operationally relevant objects, and handoff-ready packages without implying certification, procurement, finance, insurance, public authority approval, deployment, or execution.

28.15.1.3 Readiness is record-based and context-specific. A digital object may be mature for learning use but immature for operational use; mature for public-safe explanation but not for public authority use; mature for controlled review but not for public release.

### 28.15.2 Readiness Dimensions

28.15.2.1 Digital object readiness may include concept maturity, technical maturity, documentation maturity, evidence maturity, security maturity, privacy maturity, data governance maturity, AI governance maturity, interoperability maturity, accessibility maturity, public-safe maturity, maintainer maturity, dependency maturity, license maturity, correction maturity, release maturity, and handoff maturity.

28.15.2.2 TRL 1–10 references should be applied carefully to digital objects and should identify the specific context being assessed.

28.15.2.3 Grid readiness records should identify assumptions, limitations, evidence basis, review status, correction status, and downstream restrictions.

### 28.15.3 Readiness Records

28.15.3.1 Grid and TRL Digital Object Readiness Records should identify object, maturity dimension, TRL reference where used, evidence basis, reviewer, limitations, release class, correction status, downgrade status, suspension status, withdrawal status, and archive reference.

28.15.3.2 Readiness changes must propagate to Marketplace, Registry, public dashboards, release packages, Rails routes, and handoff packages where relevant.

### 28.15.4 Readiness Boundary

28.15.4.1 Grid or TRL readiness status does not create certification, procurement status, financeability, insurance approval, public authority approval, deployment authorization, or execution authority.

28.15.4.2 Readiness records describe maturity context only.

## 28.16 Foundry Release Classes

### 28.16.1 Foundry Release Class Function

28.16.1.1 **Foundry Release Classes** classify Nexus Foundry outputs according to their maturity, review status, access class, evidence sufficiency, security posture, public-safe status, Grid readiness, Rails readiness, handoff readiness, correction status, and archive status.

28.16.1.2 Release classes prevent premature movement of ideas, prototypes, draft objects, unreviewed builds, restricted materials, or sponsor-supported outputs into public dashboards, public-good releases, Nexus Core validation, Grid inputs, Rails routes, or handoff packages.

28.16.1.3 Release classes are governance signals, not marketing labels.

### 28.16.2 Release Class Categories

28.16.2.1 Foundry Release Classes may include concept, exploratory, experimental, draft, internal, controlled, restricted, protected, public-safe draft, public-good candidate, Universe-preparing, Universe-ready, Grid-ready, Rails-ready, handoff-ready candidate, returned for correction, held, superseded, withdrawn, retired, archived, and legal-hold.

28.16.2.2 Each release class should define permitted access, permitted use, prohibited use, publication status, validation eligibility, public dashboard eligibility, Marketplace eligibility, Registry status, Grid eligibility, Rails eligibility, handoff eligibility, and correction requirements.

28.16.2.3 Release class elevation requires review; release class downgrade requires correction record where material.

### 28.16.3 Release Class Records

28.16.3.1 Foundry Release Class Records should identify object, current class, prior class, review basis, required controls, limitations, correction status, effective date, responsible reviewer, and archive reference.

28.16.3.2 Release class records should link to Dockets, Foundry Program Cards, BuildGrid Cards, Evidence Packs, Grid records, Rails records, and handoff packages where applicable.

### 28.16.4 Release Class Boundary

28.16.4.1 Foundry Release Class status does not create certification, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

28.16.4.2 Release classes govern movement inside the Nexus public-good stack only.

## 28.17 BuildGrid Release Packages

### 28.17.1 BuildGrid Release Package Function

28.17.1.1 **BuildGrid Release Packages** are assembled, versioned, reviewable bundles of BuildGrid outputs, including code, data, models, documentation, tests, benchmark tools, dashboard components, public-safe report components, learning objects, schemas, APIs, Evidence Pack components, Grid components, Rails components, and handoff package components.

28.17.1.2 Release Packages convert distributed work into usable, reviewable, reusable, and correctionable public-good objects or controlled objects.

28.17.1.3 A Release Package must not be released merely because work was completed. It must pass applicable review gates.

### 28.17.2 Release Package Requirements

28.17.2.1 A BuildGrid Release Package should include package identity, version, source tasks, contributors, maintainers, license, dependencies, tests, security scan status, data classification, model inventory where applicable, documentation, public-safe review, accessibility review where applicable, release class, correction pathway, and archive reference.

28.17.2.2 Release Packages must be screened for secrets, PII, protected knowledge, license conflicts, unsafe dependencies, unreviewed AI outputs, restricted telemetry, public authority-sensitive content, capital-reader content, insurance-reader content, and handoff-only content.

28.17.2.3 Release Packages may be public, public-safe, controlled, restricted, sovereign, protected, Universe-ready, Grid-ready, Rails-ready, handoff-ready, withdrawn, retired, or archived.

### 28.17.3 Release Package Records

28.17.3.1 BuildGrid Release Package Records should identify package, contents, contributors, reviewers, release class, test status, security status, license status, public-safe status, correction history, deprecation status, and archive reference.

28.17.3.2 Release Package corrections must propagate to repositories, Marketplace listings, Registry entries, dashboards, reports, Grid inputs, Rails routes, and handoff packages where affected.

### 28.17.4 Release Package Boundary

28.17.4.1 BuildGrid Release Packages do not create warranty, certification, procurement status, financeability, insurance approval, public authority approval, deployment authorization, or execution authority.

28.17.4.2 They bundle reviewed work for defined use only.

## 28.18 Repository Security

### 28.18.1 Repository Security Function

28.18.1.1 **Repository Security** governs repositories used for software, data, models, documentation, schemas, APIs, dashboards, reports, learning objects, Evidence Packs, Stack Passport components, Grid components, Rails components, handoff packages, and archive records.

28.18.1.2 Repositories are part of the evidence infrastructure. A compromised repository can compromise software integrity, public-good release integrity, benchmark integrity, evidence integrity, public dashboards, and handoff packages.

28.18.1.3 Repository security applies to public repositories, private repositories, controlled repositories, restricted repositories, sovereign repositories, protected repositories, and archive repositories.

### 28.18.2 Repository Security Requirements

28.18.2.1 Repository security should include role-based access, protected branches, code review, signed commits where appropriate, secret scanning, dependency scanning, vulnerability alerts, issue controls, release controls, backup, audit logs, license review, contributor controls, and archive controls.

28.18.2.2 Repositories must not contain secrets, credentials, unreviewed PII, protected knowledge, restricted telemetry, public authority-sensitive materials, cyber-sensitive details, capital-reader materials, insurance-reader materials, or handoff-only content unless specifically controlled and access-restricted.

28.18.2.3 Public repositories must be reviewed before publication and periodically reviewed for leaks, dependency issues, and outdated claims.

### 28.18.3 Repository Security Records

28.18.3.1 Repository Security Records should identify repository, owner or maintainer, access class, access list, security controls, scans, incidents, corrections, release status, and archive reference.

28.18.3.2 Repository incidents must trigger containment, correction, downstream review, and archive update.

### 28.18.4 Repository Security Boundary

28.18.4.1 Repository security status does not create cybersecurity certification, software warranty, procurement status, financeability, insurance approval, public authority approval, deployment authorization, or execution authority.

28.18.4.2 It protects repository integrity only.

## 28.19 Release Governance

### 28.19.1 Release Governance Function

28.19.1.1 **Release Governance** defines the rules for approving, versioning, publishing, limiting, restricting, correcting, superseding, withdrawing, retiring, and archiving Nexus digital public-good objects and controlled technical objects.

28.19.1.2 Release Governance ensures that objects leave Foundry, BuildGrid, Nexus Core, Nexus Studio, Nexus Academy, Nexus Observatory, Nexus Reports, Nexus Grid, or Nexus Rails only with appropriate review, documentation, classification, license, security, public-safe status, and correction pathway.

28.19.1.3 Release is a record event. It is not a casual upload.

### 28.19.2 Release Requirements

28.19.2.1 Release review should consider purpose, release class, object type, access class, evidence basis, documentation, license, dependencies, security review, privacy review, protected knowledge review, public authority sensitivity, cyber sensitivity, public-safe review, accessibility review, AI-use status, maintainer assignment, correction pathway, and archive plan.

28.19.2.2 Release types may include internal release, controlled release, restricted release, public-safe release, public-good open release, Universe-ready release, Grid-ready release, Rails-ready release, handoff-ready release, emergency correction release, deprecation release, and archive release.

28.19.2.3 Release approvals, limitations, and withdrawals must be recorded.

### 28.19.3 Release Records

28.19.3.1 Release Records should identify object, version, release class, review status, approver role, limitations, dependencies, license, security status, public-safe status, correction pathway, and archive reference.

28.19.3.2 Release records should link to Registry and Marketplace status where applicable.

### 28.19.4 Release Governance Boundary

28.19.4.1 Release Governance does not create certification, procurement status, financeability, insurance approval, public authority approval, deployment authorization, or execution authority.

28.19.4.2 Release permits use under defined terms and limitations only.

## 28.20 License Governance

### 28.20.1 License Governance Function

28.20.1.1 **License Governance** governs the legal and public-good terms under which Nexus software, data, models, documentation, schemas, APIs, dashboards, learning objects, reports, and other digital public-good objects may be used, copied, modified, distributed, displayed, referenced, or incorporated into other work.

28.20.1.2 License Governance protects reuse while preventing enclosure, misuse, sponsor capture, provider capture, public-good asset privatization, unclear rights, incompatible dependencies, and unauthorized release of restricted materials.

28.20.1.3 License choice must reflect object type, source rights, contributor rights, data restrictions, model restrictions, public-safe status, protected knowledge controls, sovereign data conditions, and public-good purpose.

### 28.20.2 License Requirements

28.20.2.1 License review should identify object type, copyright status, contributor rights, third-party dependencies, data rights, model rights, documentation rights, sponsor contributions, provider contributions, public authority materials, community materials, protected knowledge restrictions, permitted uses, prohibited uses, attribution requirements, warranty disclaimers, and termination or withdrawal conditions.

28.20.2.2 Public-good licenses should preserve reuse while preventing false claims of certification, endorsement, public authority approval, procurement status, financeability, insurance approval, deployment authorization, or execution authority.

28.20.2.3 Restricted, controlled, sovereign, protected, or handoff-only objects may require non-open licenses, access terms, data-use agreements, or no-release status.

### 28.20.3 License Records

28.20.3.1 License Governance Records should identify object, license, rights holder, contributors, third-party dependencies, restrictions, attribution requirements, prohibited uses, compatibility review, correction status, and archive reference.

28.20.3.2 License conflicts must be corrected before public release where material.

### 28.20.4 License Governance Boundary

28.20.4.1 A license does not create certification, warranty, procurement approval, public authority approval, financeability, insurance approval, deployment authorization, or execution authority.

28.20.4.2 A license permits legal use under stated terms only.

## 28.21 Contributor Governance

### 28.21.1 Contributor Governance Function

28.21.1.1 **Contributor Governance** defines how individuals, teams, universities, companies, public-good groups, sponsors, providers, communities, students, youth participants, Competence Cells, National Teams, and other contributors may contribute to Nexus digital public-good objects, controlled objects, open technical assets, software commons, data commons, model commons, documentation, reports, learning objects, and release packages.

28.21.1.2 Contributor Governance ensures that contribution remains recorded, reviewable, rights-aware, secure, non-extractive, public-good aligned, and correctionable.

28.21.1.3 Contribution does not create authority. A contributor does not become a maintainer, approver, certifier, public authority, procurement actor, finance actor, or execution actor by contributing.

### 28.21.2 Contributor Requirements

28.21.2.1 Contributor rules should define eligibility, identity requirements appropriate to work class, contributor license terms where applicable, code of conduct, review process, maintainer role, attribution, public recognition, youth safeguards, privacy rules, protected knowledge rules, sponsor conflict rules, provider conflict rules, data restrictions, AI-use disclosure, and correction obligations.

28.21.2.2 High-risk contributions involving AI, cyber, data, public authority materials, protected knowledge, dashboards, Evidence Packs, Grid inputs, Rails routes, or handoff packages require heightened review.

28.21.2.3 Sponsor or provider contributors must disclose relevant conflicts and may not convert contribution into validation or control.

### 28.21.3 Contributor Records

28.21.3.1 Contributor Governance Records should identify contributor, contribution, role, rights status, review status, accepted status, release class, attribution status, conflict status, correction status, and archive reference.

28.21.3.2 Contributor records involving youth or protected participants must apply privacy and safeguard controls.

### 28.21.4 Contributor Governance Boundary

28.21.4.1 Contributor status does not create employment, contracting status, procurement qualification, certification, public authority approval, financeability, insurance approval, deployment authorization, or execution authority.

28.21.4.2 Contribution creates a reviewed work record only.

## 28.22 Dependency and Supply-Chain Controls

### 28.22.1 Dependency and Supply-Chain Function

28.22.1.1 **Dependency and Supply-Chain Controls** govern the third-party software, libraries, models, datasets, APIs, cloud services, infrastructure services, hardware dependencies, container images, build tools, development tools, AI tools, dashboard components, and documentation sources used in Nexus digital public-good objects and controlled objects.

28.22.1.2 Dependency and supply-chain risks can compromise security, licensing, reproducibility, evidence integrity, public-safe release, public authority trust, capital-readiness interpretation, insurance-readiness evidence, and lawful handoff packages.

28.22.1.3 A public-good object is only as trustworthy as its dependency record permits.

### 28.22.2 Dependency Requirements

28.22.2.1 Dependency controls should include software bill of materials where appropriate, model inventory, data inventory, license review, vulnerability scanning, provenance review, version pinning where appropriate, update policy, dependency risk classification, deprecated dependency tracking, build reproducibility, container security, and correction pathway.

28.22.2.2 High-risk dependencies involving AI models, cryptography, security tools, public dashboards, telemetry systems, data rooms, cyber ranges, public authority systems, or handoff packages require heightened review.

28.22.2.3 Undisclosed dependencies that materially affect performance, security, licensing, data handling, or evidence integrity must be corrected.

### 28.22.3 Dependency Records

28.22.3.1 Dependency and Supply-Chain Records should identify object, dependency, version, source, license, vulnerability status, provenance, update status, risk class, correction status, and archive reference.

28.22.3.2 Dependency changes must be versioned and propagated to release records, security records, Marketplace listings, Registry status, Grid inputs, Rails routes, and handoff packages where affected.

### 28.22.4 Dependency Boundary

28.22.4.1 Dependency review does not create warranty, cybersecurity certification, procurement status, financeability, insurance approval, public authority approval, deployment authorization, or execution authority.

28.22.4.2 It records dependency risk and controls only.

## 28.23 Public Release Controls

### 28.23.1 Public Release Control Function

28.23.1.1 **Public Release Controls** govern the final review and publication of digital public-good objects, open technical assets, software, data, models, dashboards, APIs, reports, learning objects, visualization objects, reference implementations, benchmark tools, and public archive materials.

28.23.1.2 Public release is irreversible in practical terms even when correction is possible. A released object can be copied, cited, reused, misunderstood, misrepresented, or incorporated into external systems. Nexus Universe therefore treats public release as a high-discipline act.

28.23.1.3 No object should be publicly released unless it has passed applicable security, privacy, license, public-safe, protected knowledge, data, AI, accessibility, and claims review.

### 28.23.2 Public Release Requirements

28.23.2.1 Public Release Controls should include final classification review, PII review, protected knowledge review, geospatial review, cyber-sensitive review, public authority-sensitive review, license review, dependency review, security review, AI-use review, accessibility review, public-safe wording review, claims boundary review, maintainer assignment, correction pathway, and archive plan.

28.23.2.2 Public releases must include version, license, limitations, no-warranty notice where applicable, no-certification notice, no-procurement notice, no-finance notice, no-insurance notice, no-public-authority-approval notice, no-deployment notice, and no-execution notice where relevant.

28.23.2.3 Public release must not be driven by sponsor timing, media timing, public authority pressure, capital-reader interest, national pride, or marketing demand where review is incomplete.

### 28.23.3 Public Release Records

28.23.3.1 Public Release Records should identify object, version, release date, release class, reviewers, checks passed, limitations, license, correction pathway, withdrawal pathway, and archive reference.

28.23.3.2 Public release errors must be corrected through public-safe correction notices, repository corrections, dashboard corrections, report corrections, Marketplace corrections, Registry corrections, and archive updates.

### 28.23.4 Public Release Boundary

28.23.4.1 Public release does not create warranty, certification, procurement status, financeability, insurance approval, public authority approval, community consent, deployment authorization, or execution authority.

28.23.4.2 Public release makes the object available under stated terms only.

## 28.24 Correction and Deprecation

### 28.24.1 Correction and Deprecation Function

28.24.1.1 **Correction and Deprecation** governs how digital public-good objects, controlled technical objects, software, data, models, schemas, APIs, dashboards, reports, learning objects, Marketplace listings, Registry entries, release packages, Grid inputs, Rails routes, and handoff packages are corrected, limited, downgraded, deprecated, superseded, withdrawn, retired, or archived.

28.24.1.2 Correction preserves trust when objects change, fail, become unsafe, become outdated, expose restricted information, contain errors, rely on vulnerable dependencies, carry license issues, misstate evidence, overclaim public authority, overclaim finance-readiness, overclaim community consent, or no longer represent current status.

28.24.1.3 Deprecation is not failure by default. It is a controlled way to prevent outdated objects from continuing to appear current.

### 28.24.2 Correction and Deprecation Actions

28.24.2.1 Actions may include patch release, documentation correction, security correction, dependency update, data correction, model correction, schema migration, API version change, dashboard correction, report correction, learning object correction, license correction, public-safe notice, Registry status change, Marketplace delisting, Grid downgrade, Rails hold, handoff correction, deprecation notice, withdrawal, retirement, and archive annotation.

28.24.1.2 Correction must identify affected downstream users and systems where feasible, including repositories, dashboards, reports, Marketplace listings, Registry entries, public archives, Grid inputs, Rails routes, handoff packages, and learning objects.

28.24.2.3 Critical corrections may require immediate containment, release freeze, access restriction, public-safe notice, or Incident Review Board escalation.

### 28.24.3 Correction and Deprecation Records

28.24.3.1 Correction and Deprecation Records should identify object, issue, severity, corrective action, version affected, version replacing it, downstream effects, public-safe notice status, deprecation date, retirement date where applicable, and archive reference.

28.24.3.2 Records should distinguish corrected, superseded, deprecated, withdrawn, retired, and archived statuses.

### 28.24.4 Correction and Deprecation Boundary

28.24.4.1 Correction or deprecation does not create certification, procurement status, financeability, insurance approval, public authority approval, deployment authorization, or execution authority.

28.24.4.2 Correction and deprecation preserve record truth only.

## 28.25 Archive and Long-Term Support

### 28.25.1 Archive and Long-Term Support Function

28.25.1.1 **Archive and Long-Term Support** governs the long-term preservation, maintenance, security, accessibility, correction, deprecation, and retirement of digital public-good objects and controlled technical objects created through Nexus Universe.

28.25.1.2 Archive preserves institutional memory. Long-term support preserves selected objects that remain important for reuse, learning, public-good continuity, National Portfolios, Grid records, Rails routes, public dashboards, public-safe reports, open technical baselines, and lawful handoff context.

28.25.1.3 Not every object receives long-term support. Some objects are archived as historical, superseded, experimental, deprecated, withdrawn, retired, or non-continuing records.

### 28.25.2 Archive and Support Requirements

28.25.2.1 Archive and Long-Term Support should identify object status, support class, maintainer, repository status, access class, license, dependency status, security status, public-safe status, correction pathway, retention period, legal hold status, deprecation status, retirement status, and archive reference.

28.25.2.2 Long-term support may include security patches, dependency updates, documentation updates, compatibility updates, schema migration, public-safe correction, accessibility update, translation update, and archive integrity review.

28.25.2.3 Archive must preserve enough information to understand what an object was, what version existed, what evidence supported it, what limitations applied, what corrections occurred, and whether it remains current.

### 28.25.3 Archive and Support Records

28.25.3.1 Archive and Long-Term Support Records should identify object, support class, maintainer, support period, update history, correction history, deprecation status, withdrawal status, retirement status, preservation location, access class, and archive reference.

28.25.3.2 Archive records must distinguish current support from historical preservation.

### 28.25.4 Final Digital Public-Good Rule

28.25.4.1 No digital public-good object, open technical asset, software asset, data object, model object, dashboard, API, report, learning object, release package, Marketplace listing, Registry entry, Grid input, Rails route, or handoff package may be treated as trustworthy merely because it exists. It must be classified, sourced, versioned, reviewed, licensed, secured, bounded, corrected, and archived.

28.25.4.2 The final digital public-good rule is that Nexus Universe turns technical work into reusable public-good infrastructure only when the object remains governed by provenance, security, license discipline, public-safe release, correctionability, archive integrity, and no-conversion boundaries.
