# XXVII. METRICS

Metrics define how Nexus observes system health, learning progress, reuse, and correction without turning signals into rankings or approvals.

It sets boundaries for interpretation, display, and use without implying certification, procurement, finance, public authority action, or execution.

## 27.1 Metrics Doctrine

### 27.1.1 Metrics as Learning, Not Ranking

Metrics as learning, not ranking is the doctrine that Nexus metrics shall be designed, recorded, reviewed, displayed, interpreted, corrected, and archived as learning instruments for public-good system health, capability formation, reuse, evidence quality, correction, accessibility, localization, portfolio maturity, and operational improvement, and not as rankings of countries, communities, providers, institutions, learners, public authorities, funders, insurers, donors, sponsors, National Nodes, Working Groups, Competence Cells, or lawful handoff recipients.

Metrics may help Nexus identify gaps, refresh needs, support needs, data-quality needs, review bottlenecks, public-safe release bottlenecks, accessibility failures, localization needs, Registry incompleteness, Marketplace discovery gaps, Grid and TRL documentation gaps, correction delays, archive weaknesses, National Portfolio maturity inputs, public authority learning activity, finance-readiness question completion, human capability formation, and adoption patterns. Metrics shall not be converted into league tables, social scores, procurement signals, finance signals, public authority decisions, provider validation, community legitimacy scores, employment decisions, or execution authority.

A Metrics-as-Learning Record should identify:

1. metric object, including object metric, metadata metric, Registry metric, Marketplace metric, software metric, data metric, model metric, security metric, public-safe metric, accessibility metric, localization metric, reuse metric, correction metric, portfolio metric, mission metric, capability metric, adoption metric, or archive metric;
2. learning purpose, including system improvement, evidence improvement, data-quality improvement, reuse intelligence, support planning, accessibility improvement, localization planning, public-safe release improvement, correction improvement, National Portfolio learning, Academy learning, Foundry learning, Campaign learning, Studio learning, Registry improvement, Marketplace improvement, Grid improvement, or handoff dependency improvement;
3. permitted interpretation, including trend, gap, completeness, freshness, readiness question, support need, review need, correction need, archive need, learning signal, adoption signal, reuse signal, or improvement signal;
4. prohibited interpretation, including country ranking, country score, provider ranking, provider validation, procurement signal, finance signal, insurance signal, donor signal, public finance signal, community score, social score, learner ranking, employment decision, public authority decision, consent determination, deployment authorization, or execution authority;
5. display controls, including non-ranking display, context notes, confidence notes, denominator notes, limitation notes, non-comparability notices where appropriate, public-safe display, accessibility display, correction channel, archive status, and non-current notice;
6. boundary notices, confirming that Nexus metrics support learning and improvement only and do not rank, approve, certify, procure, finance, insure, allocate public finance, validate providers, score communities, determine employment, authorize deployment, or execute implementation.

Metrics help Nexus learn where the system is healthy or weak. They shall not become a substitute for judgment, authority, consent, procurement, finance, or execution.

### 27.1.2 Metrics as Public-Good System Health

Metrics as public-good system health is the doctrine that Nexus metrics shall measure the condition of the public-good stack itself: whether records are complete, metadata is usable, releases are public-safe, accessibility is present, localization is advancing, software and data are maintained, models are documented, security review is occurring, corrections are timely, archives are intact, reuse is visible, and handoff dependencies are clear.

Public-good system health metrics shall focus on the reliability, transparency, completeness, safety, inclusiveness, continuity, and correctionability of Nexus objects and processes. They shall not imply that a country, provider, project, community, public authority, funder, insurer, donor, or enterprise recipient is better, worse, approved, finance-ready, procurement-ready, deployable, or execution-ready.

A Public-Good System Health Metric Record should identify:

1. health domain, including object completeness, metadata completeness, Registry status completeness, Marketplace listing quality, software release quality, data quality, model governance completeness, security review completion, public-safe release rate, accessibility completion, localization completion, reuse signals, correction velocity, deprecation discipline, archive integrity, support status, or continuity status;
2. system layer, including Reports, Registry, Marketplace, Grid, Studio, Academy, Campaigns, Foundry, DRI, Observatory, National Portfolios, Nexus Universe outputs, infrastructure, handoff packages, archives, or correction systems;
3. measurement basis, including numerator, denominator, review period, source record, steward, status class, confidence note, limitation note, data freshness, and correction status;
4. improvement use, including prioritizing review, improving documentation, increasing accessibility, refreshing data, correcting metadata, localizing content, improving public-safe release, strengthening security review, improving archive integrity, or reducing correction delays;
5. misuse controls, including no ranking, no procurement signal, no finance signal, no provider validation, no country score, no community score, no social scoring, no employment use, no public authority decision, and no execution claim;
6. boundary notices, confirming that system health metrics describe the health of Nexus public-good operations and do not approve, rank, finance, insure, procure, consent, deploy, or execute.

System health metrics keep Nexus accountable to its own public-good quality.

### 27.1.3 Metrics as Reuse Intelligence

Metrics as reuse intelligence is the doctrine that Nexus may use metrics to understand whether digital public goods, Reports, datasets, software objects, models, dashboards, Studio workflows, Academy objects, Campaign objects, Registry records, Marketplace listings, Grid records, DRI outputs, Observatory summaries, National Portfolio objects, Nexus Universe outputs, public-safe summaries, and handoff packages are being found, reused, adapted, localized, cited, forked, mirrored, translated, corrected, or routed.

Reuse intelligence shall help identify useful objects, orphaned objects, high-maintenance objects, localization needs, support needs, documentation gaps, Academy uptake, Campaign uptake, Foundry uptake, Marketplace discovery patterns, Registry status needs, and handoff dependency patterns. Reuse intelligence shall not be treated as market validation, procurement demand, provider validation, financeability, insurability, investment signal, donor priority, public finance priority, public authority adoption, or execution readiness.

A Reuse Intelligence Metric Record should identify:

1. reuse object, including software, dataset, model, API, dashboard, Report, Academy module, Campaign object, Studio workflow, DRI output, Observatory summary, Registry record, Marketplace listing, Grid input, National Portfolio object, Nexus Universe output, or handoff package;
2. reuse signal, including download, view, fork, mirror, citation, API use, translation, adaptation, Academy use, Campaign use, Foundry use, Studio use, Registry linkage, Marketplace discovery, Grid linkage, National Node use, public authority learning use, finance-readiness room use, handoff package use, correction request, or archive access;
3. signal limits, including incomplete telemetry, privacy limits, offline use, low-bandwidth use, mirror effects, bot filtering, internal use, public-safe restrictions, access-class restrictions, and non-comparable contexts;
4. improvement use, including documentation improvement, localization prioritization, support planning, accessibility improvement, security review prioritization, public-safe release improvement, Academy pathway improvement, Marketplace improvement, Registry correction, Grid improvement, and archive improvement;
5. misuse controls, including reuse-not-endorsement, reuse-not-procurement-demand, reuse-not-finance-signal, reuse-not-provider-validation, reuse-not-public-authority-adoption, reuse-not-community-consent, and reuse-not-execution-readiness;
6. boundary notices, confirming that reuse intelligence supports learning about public-good usefulness and does not create market validation, procurement approval, financeability, insurability, donor commitment, public finance allocation, public authority approval, consent, deployment authorization, or execution.

Reuse is a learning signal. It is not approval, demand, finance, procurement, or authority.

### 27.1.4 Metrics as Correction Signals

Metrics as correction signals is the doctrine that Nexus metrics shall help detect defects, stale records, missing metadata, delayed corrections, unsupported objects, accessibility failures, localization failures, public-safe release failures, Registry status gaps, Marketplace listing gaps, Grid gaps, unresolved dependencies, incident clusters, handoff overclaims, archive weaknesses, and boundary risks.

Correction-signal metrics shall be used to improve records, trigger review, prioritize repair, initiate stop-the-line where necessary, update support status, downgrade status, suspend display, recall handoff packages, correct public-safe releases, and improve recurrence prevention. They shall not be used to punish countries, communities, contributors, learners, providers, public authorities, funders, insurers, donors, sponsors, or National Nodes through ranking or social scoring.

A Correction Signal Metric Record should identify:

1. correction signal, including missing metadata, stale data, unresolved issue, unresolved incident, delayed patch, delayed erratum, unreviewed release, public-safe defect, accessibility defect, localization defect, security review gap, dependency gap, Registry mismatch, Marketplace overclaim, Grid mismatch, handoff defect, archive inconsistency, or support-status mismatch;
2. affected object, including software, dataset, model, API, dashboard, Report, Campaign material, Academy object, Studio workflow, DRI output, Observatory summary, Registry record, Marketplace listing, Grid record, National Portfolio object, Nexus Universe output, handoff package, infrastructure record, or archive object;
3. trigger pathway, including maintainer review, public-safe review, safeguard review, security review, data review, AI review, accessibility review, localization review, Registry correction, Marketplace correction, Grid correction, stop-the-line trigger, handoff correction, handoff recall, or archive correction;
4. severity class, including low, moderate, material, public-safe-critical, security-critical, protected-knowledge-critical, public authority-boundary-critical, finance-boundary-critical, procurement-boundary-critical, consent-boundary-critical, handoff-critical, execution-overclaim-critical, or archive-critical;
5. response status, including triaged, under review, corrected, downgraded, suspended, withdrawn, recalled, archived, sealed, deletion-required, reinstated, or non-continuing;
6. boundary notices, confirming that correction-signal metrics support repair and recurrence prevention and do not create ranking, blame, public authority action, procurement signal, finance signal, provider validation, employment decision, deployment authorization, or execution.

Correction signals are early-warning instruments for Nexus integrity, not scoring instruments for people or countries.

### 27.1.5 Metrics Without Country Ranking

Metrics without country ranking is the mandatory rule that Nexus metrics shall not rank countries, compare countries in league tables, assign national scores, create national performance labels, imply national superiority, imply national failure, imply public authority endorsement, imply policy approval, imply public finance priority, imply investment priority, or turn National Portfolio records into country rankings.

Nexus may maintain National Portfolio maturity inputs, National Node adoption records, National Working Group records, Competence Cell records, DRI refresh records, Observatory signal quality records, public authority learning records, Academy records, Campaign records, localization records, accessibility records, correction records, and handoff dependency records. Such records shall be displayed as context, learning, readiness questions, and system-health signals, not national rankings.

A No-Country-Ranking Metric Record should identify:

1. national metric, including National Portfolio maturity input, National Node adoption, national repository completeness, localization completion, Academy participation, Campaign participation, DRI refresh, Observatory signal quality, public authority learning record, finance-readiness question completion, handoff dependency readiness, or correction velocity;
2. non-ranking design, including country profile, national context record, maturity input, progress note, gap note, support need, readiness question, learning status, or internal dashboard with no league table;
3. display restrictions, including no ordinal ranking, no country score, no traffic-light public ranking unless internally governed and non-ranking, no public comparison without context, no investment-priority display, no donor-priority display, no procurement-priority display, and no public authority approval implication;
4. context requirements, including national ownership, data availability differences, capacity differences, language differences, infrastructure differences, public authority dependency differences, safeguard differences, conflict or disaster context where relevant, and non-comparability notes;
5. correction pathway, including national context correction, data correction, public-safe correction, Registry correction, Marketplace correction, Grid correction, public repair where required, archive, and non-current notice;
6. boundary notices, confirming that national metrics are learning inputs only and do not rank countries, approve governments, prioritize finance, allocate public finance, validate policy, authorize procurement, or execute implementation.

National metrics support national ownership. They shall not become national scoring.

### 27.1.6 Metrics Without Provider Validation

Metrics without provider validation is the mandatory rule that Nexus metrics shall not validate providers, rank providers, score vendors, create preferred-provider status, imply supplier approval, imply procurement readiness, imply security approval, imply financeability, imply insurability, or create market endorsement.

Provider-related metrics may document contribution records, support records, dependency status, provider-neutrality controls, support limitations, security review completion within Nexus scope, Marketplace listing quality, Registry completeness, portability status, issue response within Nexus scope, and correction status. Such metrics shall be used for dependency awareness and public-good operations, not vendor validation.

A No-Provider-Validation Metric Record should identify:

1. provider-related metric, including contribution count, support status, dependency status, uptime where applicable, issue response, Marketplace listing completeness, Registry record completeness, security review completion within Nexus scope, documentation completeness, portability status, correction status, or support expiry;
2. permitted use, including support planning, dependency mapping, provider-neutrality review, portability planning, issue routing, Registry correction, Marketplace correction, handoff dependency awareness, and archive;
3. prohibited use, including provider ranking, vendor validation, preferred-provider designation, procurement recommendation, supplier approval, security certification, investment signal, insurance signal, public authority endorsement, deployment authorization, or execution readiness;
4. display controls, including provider-neutral wording, no leaderboard, no comparative score, no procurement language, no finance language, no endorsement language, support-without-validation notice, and contribution-without-validation notice;
5. correction pathway, including provider wording correction, Marketplace correction, Registry correction, Report correction, handoff correction, public repair where required, archive, and non-current notice;
6. boundary notices, confirming that provider-related metrics describe Nexus dependency and support context only and do not validate providers, recommend procurement, approve suppliers, finance, insure, authorize deployment, or execute implementation.

Provider metrics are dependency records. They are not market ratings.

### 27.1.7 Metrics Without Procurement Signal

Metrics without procurement signal is the mandatory rule that Nexus metrics shall not be represented or used as procurement scoring, tender evaluation, supplier prequalification, vendor ranking, award justification, procurement recommendation, purchasing signal, public procurement decision, or tender support by implication.

Metrics may help identify object completeness, public-safe status, security review completion, accessibility completion, localization completion, support status, reliability status, Registry completeness, Marketplace listing quality, Grid context, and handoff dependency readiness. Such metrics may inform independent diligence by lawful recipients but shall not replace procurement process or supplier evaluation.

A No-Procurement-Signal Metric Record should identify:

1. metric with procurement-risk context, including Marketplace metric, Registry metric, Grid metric, support metric, provider contribution metric, software quality metric, security review metric, reliability metric, adoption metric, reuse metric, National Portfolio metric, or handoff readiness metric;
2. procurement-risk pathway, including supplier comparison, vendor validation, procurement score, preferred provider, tender support, specification support, award justification, public authority procurement implication, or Project SPV procurement implication;
3. required controls, including no-procurement notice, no-preferred-provider notice, no-vendor-validation notice, independent diligence required, provider-neutrality review, Marketplace wording control, Registry wording control, handoff procurement boundary, and correction channel;
4. permitted use, including internal improvement, public-good system health, support planning, dependency awareness, discovery quality, readiness questions, handoff dependency context, and independent diligence awareness;
5. prohibited use, including procurement decision, tender evaluation, supplier approval, vendor ranking, award recommendation, or procurement authorization;
6. boundary notices, confirming that metrics are not procurement signals and do not create supplier approval, tender support, procurement decision, deployment authorization, or execution.

Metrics may show whether Nexus records are complete. They shall not tell anyone whom to buy from.

### 27.1.8 Metrics Without Finance Signal

Metrics without finance signal is the mandatory rule that Nexus metrics shall not be represented or used as financeability, bankability, investability, creditworthiness, insurability, underwriting readiness, donor priority, public finance priority, financial rating, investment signal, insurance signal, donor allocation signal, public finance allocation signal, or transaction signal.

Finance-readiness metrics may document assumptions registers, dependency registers, diligence-gap registers, finance-readiness question completion, insurance-readiness question completion, donor-readiness question completion, public finance relevance question completion, cost and support records, handoff dependency readiness, public authority dependencies, safeguard dependencies, and correction status. They shall remain no-reliance, non-soliciting, non-transactional, and bounded.

A No-Finance-Signal Metric Record should identify:

1. finance-adjacent metric, including finance-readiness question completion, insurance-readiness question completion, donor-readiness question completion, public finance relevance question completion, assumptions register completeness, dependency register completeness, diligence-gap register completeness, handoff dependency readiness, support status, cost status, or public authority dependency status;
2. finance-risk pathway, including financeability claim, bankability claim, insurability claim, underwriting implication, donor commitment implication, public finance allocation implication, investment signal, rating signal, solicitation, transaction, or financial promotion;
3. required controls, including no-reliance notice, non-solicitation notice, non-transactionality notice, regulated-perimeter escalation where required, finance-boundary review, donor-boundary review, public finance boundary review, correction channel, and archive;
4. permitted use, including capital-readability learning, insurance-readiness questions, donor-readiness questions, public finance learning, dependency awareness, diligence-gap awareness, and handoff context;
5. prohibited use, including investment advice, insurance advice, underwriting, donor commitment, public finance allocation, rating, transaction, solicitation, financeability, insurability, or execution claim;
6. boundary notices, confirming that finance-adjacent metrics support learning and readability only and do not create finance, insurance, donor commitment, public finance allocation, investment advice, transaction, deployment authorization, or execution.

Finance-adjacent metrics help readers ask better questions. They shall not imply that capital should move.

The final Metrics Doctrine rule is: Nexus metrics are learning instruments, public-good system-health instruments, reuse-intelligence instruments, and correction signals. They shall operate without country ranking, provider validation, procurement signal, or finance signal. Metrics make Nexus more observable, improvable, and accountable; they do not rank, approve, validate, procure, finance, insure, allocate public finance, score communities, determine employment, authorize deployment, or execute implementation by implication.

## 27.2 Core Ecosystem Metrics

### 27.2.1 Object Completeness

Object completeness measures whether a Nexus object has the minimum required records for its object class, including identity, steward, source, version, purpose, access class, data-use label where applicable, AI-use label where applicable, sensitivity class where applicable, public-safe status, support class, review status, correction pathway, archive rule, and boundary notices.

An Object Completeness Metric Record should identify object class, required fields, completed fields, missing fields, steward, review status, correction need, archive status, and limitation note. Object completeness is a record-quality metric and shall not imply approval, readiness, procurement status, financeability, insurability, deployment authorization, or execution.

### 27.2.2 Metadata Completeness

Metadata completeness measures whether Nexus objects contain sufficient metadata to be findable, understandable, reusable within limits, reviewable, localizable, accessible, correctable, and archivable. Metadata may include title, identifier, description, steward, source, provenance, version, date, language, license status, data-use labels, AI-use labels, sensitivity class, public-safe status, support class, dependency links, Registry links, Marketplace links, Grid links, correction history, and archive rule.

A Metadata Completeness Metric Record should identify missing metadata, stale metadata, inconsistent metadata, localization metadata, accessibility metadata, rights metadata, public-safe metadata, and correction status.

### 27.2.3 Registry Status Completeness

Registry status completeness measures whether Registry records accurately show object identity, provenance, status, support class, release class, public-safe status, sensitivity class, correction status, withdrawal status, recall status, Grid linkage, Marketplace linkage, archive linkage, and non-current notices.

A Registry Status Completeness Metric Record should identify registered object, required status fields, completed fields, stale fields, mismatches, missing correction links, missing archive links, steward, correction pathway, and archive status. Registry completeness supports status truth and does not create certification, approval, procurement readiness, financeability, insurability, deployment authorization, or execution.

### 27.2.4 Marketplace Listing Quality

Marketplace listing quality measures whether Marketplace listings are accurate, public-safe, accessible, provider-neutral, procurement-neutral, finance-neutral, support-classified, Registry-linked, Grid-linked where applicable, localized where appropriate, and correctionable.

A Marketplace Listing Quality Metric Record should identify listing, object class, description quality, support class, provider-neutrality status, sponsor-boundary status, public-safe status, accessibility status, localization status, Registry link, Grid link, correction status, delisting status, and archive rule.

### 27.2.5 Software Release Quality

Software release quality measures whether a Nexus software object has appropriate versioning, repository status, license status, documentation, dependency records, security review status, SBOM literacy where applicable, issue pathway, public-safe documentation, installation boundaries, support class, correction pathway, release notes, deprecation policy, and archive rule.

A Software Release Quality Metric Record should identify release object, version, dependency status, security review status, documentation completeness, license status, support class, known issues, correction status, archive status, and limitation note. Software release quality is not security certification, production approval, procurement approval, deployment authorization, or execution.

### 27.2.6 Data Quality

Data quality measures whether Nexus data objects are sufficiently documented, sourced, classified, current, complete, consistent, validated within scope, uncertainty-labelled where appropriate, sensitivity-labelled, data-use-labelled, AI-use-labelled, public-safe-transformed where required, localized where appropriate, accessible where appropriate, and correctionable.

A Data Quality Metric Record should identify data source, provenance, completeness, timeliness, consistency, uncertainty, confidence, missingness, data-use label, AI-use label, sensitivity class, public-safe status, correction status, archive status, and limitation note. Data quality is not open data release, public authority approval, consent, financeability, insurability, deployment authorization, or execution.

### 27.2.7 Model Governance Completeness

Model governance completeness measures whether a Nexus model, AI workflow, simulation model, digital twin, DRI model, Observatory model, Studio model, evaluation model, or public-safe transformation model has model cards, system cards where applicable, data context, AI-use labels, intended-use statements, prohibited-use statements, evaluation records, limitation notes, red-team records where applicable, human oversight patterns, incident pathways, correction pathways, and archive rules.

A Model Governance Completeness Metric Record should identify model object, required governance records, missing records, evaluation status, limitation status, red-team status, oversight status, incident status, correction status, and archive status. Model governance completeness is not AI safety certification, public authority approval, procurement approval, financeability, insurability, deployment authorization, or execution.

### 27.2.8 Security Review Completion

Security review completion measures whether Nexus objects and environments requiring security review have completed appropriate review, including repository review, dependency scanning, secret scanning, access review, zero-trust profile, vulnerability review, SBOM literacy where applicable, incident response pathway, secure-room controls, data-room controls, API controls, infrastructure controls, and archive controls.

A Security Review Completion Metric Record should identify object, review required, review completed, gaps, unresolved risks, remediation status, support status, correction pathway, and archive rule. Security review completion is not security certification, compliance approval, procurement approval, public authority approval, deployment authorization, or execution.

### 27.2.9 Public-Safe Release Rate

Public-safe release rate measures the proportion of eligible Nexus outputs that have passed public-safe review and been released or made available to the intended audience in the correct release class, with required redactions, limitations, accessibility supports, non-command notices, no-warning notices, no-procurement notices, no-finance notices, correction channels, and archive rules.

A Public-Safe Release Rate Metric Record should identify eligible outputs, reviewed outputs, released outputs, restricted outputs, withdrawn outputs, recalled outputs, reasons for non-release, correction status, and archive status. Public-safe release rate is not full disclosure, public authority approval, procurement approval, financeability, insurability, consent, deployment authorization, or execution.

### 27.2.10 Accessibility Completion

Accessibility completion measures whether Nexus outputs have appropriate accessibility features, including accessible HTML, screen-reader compatibility, alt text, captions, transcripts, plain-language summaries, low-bandwidth versions, mobile-first formats, accessible PDFs where applicable, language accessibility, keyboard navigation where applicable, and correction channels.

An Accessibility Completion Metric Record should identify object, required accessibility features, completed features, missing features, tested features, accessibility defects, correction status, and archive status. Accessibility completion improves access and does not create new license, public authority approval, procurement approval, consent, deployment authorization, or execution.

### 27.2.11 Localization Completion

Localization completion measures whether Nexus objects have been localized for relevant national, regional, language, legal-context, public authority terminology, cultural, accessibility, low-bandwidth, offline, community-safe, and data-sovereignty contexts.

A Localization Completion Metric Record should identify object, target locale, translation status, terminology status, public-safe status, legal-equivalence notice, accessibility status, National Node review, correction status, and archive status. Localization completion is not public authority adoption, legal equivalence, national approval, procurement approval, financeability, insurability, deployment authorization, or execution.

### 27.2.12 Reuse Signals

Reuse signals measure whether Nexus objects are being found, accessed, cited, forked, mirrored, translated, adapted, used in Academy pathways, used in Campaigns, used in Foundry, linked in Registry, discovered through Marketplace, referenced in Grid, used by National Nodes, used in public authority learning, or included in handoff packages.

A Reuse Signal Metric Record should identify object, signal type, source, period, privacy controls, bot or automated-use limitations, offline-use limitations, mirror limitations, correction status, and archive status. Reuse signals are learning signals and shall not imply endorsement, procurement demand, financeability, public authority adoption, consent, deployment authorization, or execution.

### 27.2.13 Correction Velocity

Correction velocity measures the time and process quality between correction signal, issue intake, triage, review, correction action, propagation, public-safe notice where required, Registry update, Marketplace update, Grid update, handoff update where required, and archive update.

A Correction Velocity Metric Record should identify correction object, trigger time, triage time, action time, propagation time, unresolved delay, severity, steward, recurrence-prevention action, and archive rule. Correction velocity supports trust and does not create warranty, certification, approval, procurement status, or execution authority.

### 27.2.14 Deprecation Discipline

Deprecation discipline measures whether outdated, superseded, unsafe, unsupported, withdrawn, recalled, stale, non-current, or non-continuing Nexus objects are properly labelled, linked to successors where applicable, removed from current display where required, corrected in Registry, corrected in Marketplace, corrected in Grid, communicated through public-safe notices, and archived.

A Deprecation Discipline Metric Record should identify deprecated object, reason, successor link, support status, display status, Registry status, Marketplace status, Grid status, handoff status, correction status, and archive status. Deprecation discipline prevents stale authority and does not create approval, procurement readiness, deployment authorization, or execution.

### 27.2.15 Archive Integrity

Archive integrity measures whether archived Nexus objects retain required metadata, access class, non-current notices, historical use notes, successor links, correction history, license status, public-safe status, retention rule, deletion rule, sealing status, and archive steward.

An Archive Integrity Metric Record should identify archive object, required archive fields, missing fields, access-class correctness, successor-link status, correction-history completeness, public-safe status, retention status, deletion status, restore test where applicable, and archive correction need. Archive integrity preserves memory and does not create current authority, approval, procurement status, financeability, insurability, deployment authorization, or execution.

The final Core Ecosystem Metrics rule is: core ecosystem metrics measure object completeness, metadata completeness, Registry status completeness, Marketplace listing quality, software release quality, data quality, model governance completeness, security review completion, public-safe release rate, accessibility completion, localization completion, reuse signals, correction velocity, deprecation discipline, and archive integrity. These metrics improve the health of Nexus public-good objects and records; they do not rank, certify, approve, procure, finance, insure, validate providers, allocate public finance, authorize deployment, or execute implementation.

## 27.3 Portfolio and Mission Metrics

### 27.3.1 National Portfolio Maturity Inputs

National Portfolio maturity inputs measure whether a National Portfolio contains the required context records, systems-risk maps, challenge briefs, evidence need records, Observatory need records, Core Build requests, safeguard records, public authority learning records, readiness question records, Competence Cell workplans, Nexus Universe routing records, correction records, and archive records.

A National Portfolio Maturity Input Record should identify maturity input, evidence status, dependency status, missing records, public-safe status, safeguard status, public authority dependency, finance-readiness question status, correction status, and archive status.

DRF literacy progress measures whether Disaster Risk Finance learning materials, protection-gap questions, risk-layering questions, insurance-readiness questions, public finance relevance questions, donor-readiness questions, assumptions registers, dependency registers, no-reliance statements, and public-safe summaries are being created, reviewed, localized, taught, corrected, and archived.

A DRF Literacy Progress Record should identify learning object, reader class, question status, no-reliance status, public-safe status, localization status, correction status, and archive status. DRF literacy progress is not insurance approval, underwriting, financeability, donor commitment, public finance allocation, investment advice, or transaction.

### 27.3.5 DRI Refresh Rate

DRI refresh rate measures whether Disaster Risk Intelligence indicators, datasets, dashboards, Observatory linkages, Studio workflows, public-safe summaries, Reports, Registry records, Marketplace listings, Grid inputs, and National Portfolio records are refreshed within the recorded cadence, subject to data availability, public-safe review, data quality, and correction status.

A DRI Refresh Rate Record should identify indicator or object, last refresh, expected cadence, data source, freshness status, confidence status, public-safe status, degraded-mode status, correction need, and archive status. DRI refresh rate is not a public warning, official forecast, public authority decision, procurement signal, finance signal, or execution authority.

### 27.3.6 Observatory Signal Quality

Observatory signal quality measures whether Nexus Observatory signals have source records, provenance, confidence labels, uncertainty labels, timeliness, sensitivity classification, public-safe status, geospatial controls, safeguard controls, public authority boundary controls, DRI linkages, Studio linkages, National Portfolio linkages, correction pathways, and archive status.

An Observatory Signal Quality Record should identify signal, source, method, confidence, uncertainty, sensitivity, public-safe status, correction status, and archive status. Observatory signal quality is not official monitoring, public warning, public authority action, procurement signal, finance signal, or execution authority.

### 27.3.7 Public Authority Learning Records

public authority learning records measure the formation, completeness, and correction of records showing public authority learning questions, participation, materials reviewed, limitations, no-decision notices, public authority dependencies, public finance learning context, public-safe status, correction status, and archive status.

A Public Authority Learning Metric Record should identify public authority class, room or context, questions, materials, no-decision notice, dependencies, correction status, and archive status. Public authority learning records are not public authority decisions, policy adoption, regulatory approvals, procurement approvals, public finance allocations, public warnings, emergency commands, or execution authority.

### 27.3.8 Finance-Readiness Question Completion

finance-readiness question completion measures whether capital-readability, insurance-readiness, donor-readiness, and public finance relevance questions have been identified, reviewed, documented, no-reliance-labelled, dependency-linked, corrected, and archived.

A Finance-Readiness Question Completion Record should identify question class, assumptions, dependencies, diligence gaps, no-reliance status, non-solicitation status, non-transactionality status, correction status, and archive status. Question completion is not financeability, insurability, underwriting, donor commitment, public finance allocation, investment advice, solicitation, or transaction.

### 27.3.9 Handoff Dependency Readiness

handoff dependency readiness measures whether handoff packages contain complete dependency registers, recipient responsibilities, evidence context, data context, method context, public-safe status, safeguard status, public authority dependencies, legal dependencies, finance and insurance questions, procurement boundaries, provider-neutrality notes, sponsor-boundary notes, correction pathways, recall pathways, and archive rules.

A Handoff Dependency Readiness Record should identify package, dependency classes, unresolved dependencies, recipient class, review status, correction status, recall status, and archive status.
