IV. Infrastructure

4.1 Multi-Track DAG Engines with Offline-Ready Protocols

4.1.1 The Fellowship program must operate with unified DAG (Directed Acyclic Graph) engines that support real-time and offline workflows across all tracks—Research, DevOps, Media, Policy, and NWGs. These DAG engines must allow contributors to simulate, submit, verify, and synchronize clause-based work even in low-bandwidth or disconnected environments.

4.1.2 Each DAG engine must be interoperable with Nexus Ecosystem (NE) modules, including NXS-DSS (dashboard logic), NXS-AAP (anticipatory action), NXS-EWS (early warning), and NXSCore. Offline simulations must be cached and revalidated across modules upon reconnection.

4.1.3 DAGs must allow for cross-track workflows. Every contribution must be structured for compatibility with simulations and reviews from other tracks. This ensures interoperability and cross-disciplinary simulation verifiability.

4.1.4 DAG forks and concurrent offline edits must include embedded merge conflict signatures. Upon reconnection, NXS-DSS must flag conflicts for DAO resolution or corridor-level arbitration, based on quorum rules and contributor authority levels.

4.1.5 Metadata layers in every DAG include contributor zkID, clause reference, simulation lineage, SPDX license, and track affiliation. This metadata is cached and readable offline using encrypted JSON-LD or QR-encoded formats.

4.1.6 Every DAG engine must support an automatic fallback protocol: offline contributors can submit clause payloads through file upload, QR-code transfers, or low-bandwidth sync agents. These payloads must be pre-signed and queued for future DAG engine ingestion.

4.1.7 Corridor stewards or DAO delegates may co-sign offline DAGs to validate field-originated submissions. These attestations are required in governance corridors designated high-risk or sensitive by the NSF.

4.1.8 Offline DAG engines must support DAG checkpointing, rollback, and recovery from interrupted execution states. Clause memory must be preserved via secure timestamps and validated hashes, even when synced days or weeks later.

4.1.9 GUI and CLI interfaces must be designed for constrained environments, including mobile-first layouts and touchscreen support. Visual DAG editors must simplify clause logic, tagging, and metadata confirmation.

4.1.10 Reconnected DAG engines must automatically check simulation lineage and dependency trees. If upstream DAGs have changed, the system must issue alerts and trigger re-simulation of affected downstream clauses.

4.1.11 Minimum synchronization thresholds must be defined. DAGs cannot be marked as “Verified” until syncing meets quorum indicators—such as confirmation from two modules (e.g., NXS-DSS and NXS-AAP) or corridor-level DAG cross-checks.

4.1.12 Geo-tagging must be embedded into offline DAG metadata. Submissions from certain risk-weighted jurisdictions must undergo treaty compliance review or redline flagging by NSF protocols.

4.1.13 Contributors must receive dashboard alerts if a DAG sync is delayed beyond 7 days or simulation validity expires due to upstream changes. Redline flags are automatically added after 14 days without resolution.

4.1.14 All DAG-based clause bundles must be recoverable via portable backup seeds. Encrypted copies may be stored locally, exported via QR, or transferred between devices with offline vault tokens.

4.1.15 DAGs submitted through offline workflows must be reviewed by DAO delegates within 72 hours of upload. If unresolved, the system escalates to corridor arbitration and governance ethics oversight.

4.1.16 Every DAG engine must publish quarterly resilience audit results. These tests simulate emergency deployment, offline operation, metadata recovery, and full sync. Reports are posted in the Transparency Ledger.

4.1.17 Multi-track DAG engines must follow the Nexus Commons Licensing Protocol and remain open-source, with SPDX tags and RDF templates to ensure public trust and reproducibility.

4.1.18 Contributors must be trained via visual and command-line guides to create, validate, and synchronize offline DAGs. Training modules are embedded into the Fellowship Dashboard.

4.1.19 Simulation DAGs submitted offline must be assigned provisional transparency ratings (e.g., Pending Sync, Partial Validation). Final ratings are updated post-sync and review.

4.1.20 Resilient DAG engines are critical to ensuring the Fellowship can operate under any condition—disaster zones, conflict areas, or disconnected regions—while maintaining clause integrity, contributor safety, and transparent outputs aligned with public-good governance.

4.2 GitHub Delivery as Proof of Competence and Track Achievement

4.2.1 Every Fellow must maintain an active GitHub (or Git-based equivalent) repository registered with the Fellowship Dashboard and cryptographically linked to their zkID credential. This repository serves as the canonical, clause-verifiable portfolio for all Fellowship contributions across assigned tracks.

4.2.2 GitHub profiles must be identity-attested using zkID-OAuth binding, ensuring that contributions, forks, and pull requests are attributed only to verified Fellows. Dashboard role badges must map directly to GitHub commit histories.

4.2.3 Each GitHub repository must follow NSF-issued templates and track-specific folder structures. These include standardized README templates, SPDX licensing manifests, RDF metadata folders, and DAG integration stubs.

4.2.4 Repositories must reflect track-specific logic:

• Research: clause-ready RDF metadata, simulation notebooks, reproducible datasets.

• DevOps: modular codebases, CI/CD workflows, integration test runners.

• Media: source-linked creative assets, licensing tags, media DAGs.

• Policy: clause-anchored policy drafts, simulation inputs, treaty versioning.

4.2.5 Each deliverable must be issued as a signed Git commit using zkID keypairs. Commits must include DAG hashes, SPDX license identifiers, RDF metadata, and Fellowship clause tags. GitHub GPG signatures or Web3-attested push proofs are mandatory.

4.2.6 Releases must align with DAG checkpoint states. Each tagged release (e.g., v1.0-RF, v2.2-MC) must correspond to a clause simulation status such as Verified, Flagged, or Pending Arbitration. These states are mirrored in the Transparency Ledger.

4.2.7 All GitHub repositories must be linked with NXS-DSS dashboards and exposed to DAO-level observability. Metrics include: pull request frequency, contributor heatmaps, test coverage, merge veto counts, and reviewer signature quorum.

4.2.8 Multi-repo project teams must maintain a DAG-linked manifest file referencing all modular repositories. These manifests allow coordinated evaluations, joint simulation runs, and unified publication packaging.

4.2.9 GitHub repositories must sync with IPFS/Zenodo mirrors for backup and long-term reproducibility. Full snapshot mirrors must include commit history, metadata hashes, CI logs, and SPDX artifacts.

4.2.10 Governance triggers apply if:

• A Fellow falsely claims authorship of commits.

• Repositories are deleted or license violations are detected.

• Simulation statuses are manipulated post-release.

These triggers lead to redline flags, corridor arbitration, and contribution invalidation.

4.2.11 Fellowship milestones (e.g., Q1 Delivery, Deployment v1.0) must be submitted via signed release packages to the Fellowship Dashboard. These packages include: tag, release note, DAG ID, Zenodo DOI, RDF file, SPDX license, and verification link.

4.2.12 Repository hygiene requirements include: changelog maintenance, CI pass thresholds, branch protection rules, and auto-enforced SPDX + RDF compliance checks via GitHub Actions or equivalent pipelines.

4.2.13 Each pull request must pass DAG-linked simulation validation checks before merge approval. If a simulation fails or licensing is incomplete, PRs are auto-blocked.

4.2.14 Fellows’ GitHub activity contributes to real-time role observability and SIS (Safety Index Score) metrics. Commits, merges, review counts, and redline reversals feed into contributor dashboards and DAO recognition pathways.

4.2.15 GitHub delivery is mandatory for all impact scoring, DAO vote eligibility, bounty claims, and elevation into Founder Track. Contributions not published and verified through GitHub are deemed non-binding and excluded from evaluation.

4.2.16 The GitHub repository stands as the transparent, decentralized, and evidence-based portfolio for every Fellow. It is accessible to DAO stewards, ethics committees, Nexus partners, and multilateral observers and forms a pillar of open public-good accountability.

4.3 Contributor Observability: Grafana, Git Metrics, IPFS Anchoring

4.3.1 Each Fellow’s contribution activity must be continuously tracked through real-time observability dashboards using Grafana or equivalent tools. These dashboards must be accessible to DAO stewards, track mentors, and ethics review boards.

4.3.2 Observability metrics must include: frequency of contributions, review velocity, test pass rates, redline reversals, simulation success rate, DAG completion time, and corridor-adjusted score normalization. Metrics must be track-specific and weighted according to corridor complexity.

4.3.3 GitHub-linked dashboards must integrate via API to ingest CI/CD logs, commit metadata, PR activity, DAG state, and simulation results. Offline contributions and delayed DAG syncs must also be reconciled into unified observability views.

4.3.4 Each Fellow must maintain an IPFS-anchored snapshot of all tagged repository states. Each snapshot must include: signed RDF metadata, SPDX license files, clause status indicators, DAG hash lineage, and Git commit signatures. DAO Stewards must verify and co-sign snapshot metadata before it is logged in the Transparency Ledger.

4.3.5 Fellowship dashboards must include individual observability modules where contributors can access their Safety Index Score (SIS), Contributor Integrity Index (CII), and Fellowship Reputation Score (FRS). These metrics must update weekly and allow breakdowns by track, corridor, and role class.

4.3.6 Contributors must receive alerts and cooldown notifications if observability metrics fall below corridor-defined thresholds, or if flagged for governance anomalies (e.g., unresolved redlines, unverified DAGs, ethics violations). Repeat violations trigger redline arbitration and temporary role suspension.

4.3.7 IPFS-anchored snapshots must be cryptographically hashed, checkpointed with DAG reference IDs, and registered in the Transparency Ledger. Snapshots must follow a standardized file structure and license tagging format to ensure open research and machine discoverability.

4.3.8 Repository activity must feed into role-based scorecards. These scorecards are used for:

• DAO voting power allocation,

• bounty claim eligibility,

• peer review weight,

• Founder Track elevation status,

• multilateral observability compliance.

Scorecards must be audit-logged monthly and displayed on the contributor’s public Fellowship profile.

4.3.9 Observability dashboards must include cross-corridor and cross-track visualizations of deliverables completed, DAGs submitted, issues resolved, simulations approved or rejected, and system-wide trust overlays.

4.3.10 Each dashboard must expose data via RDF/JSON endpoints and SPDX license declarations to allow open-source research, machine indexing, and compatibility with SDG monitoring tools. Dashboards must also feed into Nexus Federation Observatory Protocols and treaty-linked transparency systems.

4.3.11 Contributors must be provided with formal mechanisms to challenge their scorecard metrics or appeal arbitration decisions stemming from dashboard data. DAO ethics boards must resolve appeals within a 14-day maximum review window.

4.3.12 All observability data must be governed under the Nexus Ethics Charter and zero-trust infrastructure safeguards. Sensitive jurisdictions or contributor identities flagged for risk must be granted additional privacy protections, including pseudonymous visibility modes or corridor-level encryption toggles.

4.3.13 Observability dashboards must remain fully open, cryptographically auditable, and publicly accessible, ensuring reproducibility, fairness, and global confidence in the integrity of Fellowship contributions.

4.4 Simulation Validation: zkML, RAG, CAG, TEE/Audit Layers

4.4.1 All Fellowship contributions—ranging from software code, simulation models, digital media, scientific reports, and policy drafts—must undergo comprehensive validation through a multi-layered simulation protocol incorporating zkML (zero-knowledge machine learning), RAG (retrieval-augmented generation), CAG (cache-augmented generation), and TEE (trusted execution environments). These validation layers serve to ensure factual integrity, technical reproducibility, legal compliance, and alignment with international governance standards across both online and offline corridors.

4.4.2 zkML validation must demonstrate that any AI or machine learning models used in submissions are deterministic, auditable, and resistant to adversarial manipulation. Proofs must be anchored in zero-knowledge logic that reveals outcome integrity without exposing underlying sensitive data. Model training sets must be cryptographically hashed and stored in the contributor’s SVL. Validation frequency for zkML models must follow a 90-day re-audit cycle or trigger immediately if data dependencies change.

4.4.3 RAG validation ensures that outputs—particularly those involving generative or policy-oriented content—are grounded in structured, RDF-linked external knowledge sources. Contributors must submit RAG lineage tables showing all referenced entities and the timestamped retrieval paths. Simulation outputs must be penalized if dependent on deprecated, unverified, or single-source RAG graphs without DAO verification.

4.4.4 CAG validation safeguards reproducibility and workflow stability. All Fellows must maintain an immutable cache map and demonstrate repeatability of simulation DAG outputs across cold starts, varied hardware environments, and corridor-specific runtime conditions. Cache deviation audits must be triggered on hash mismatch or unexplained variance beyond corridor thresholds. A two-cycle cooldown must apply after failed cache validation before resubmission.

4.4.5 TEE integration is required for any simulation or process involving encrypted, confidential, or corridor-sensitive data. All TEEs must produce signed attestation reports. DAO-integrated scripts must verify enclave integrity before TEE outputs are accepted. Emergency conditions (e.g., conflict zones) may invoke proxy attestation protocols, with manual quorum confirmation required post-reentry.

4.4.6 Simulation Dependency Graphs (SDGs) must be declared for every submission involving interlinked clauses, simulations, or upstream data. SDGs must reflect all parent-child relationships and include rollback handling logic. DAO stewards must sign off on SDGs before simulation results are added to any public impact registry.

4.4.7 DAO-triggered logic must govern the escalation of invalid or outlier simulations. A simulation that exceeds corridor variance limits, fails lineage resolution, or conflicts with prior validated work must automatically generate an arbitration DAG and lock the submission from affecting contributor scorecards until resolution.

4.4.8 All simulation submissions must be weighted by corridor complexity, risk classification, and clause impact level. Fellows operating in higher-risk corridors must receive simulation impact multipliers, and DAG difficulty indexes must be documented and linked to the Fellow’s performance dashboard.

4.4.9 Real-time simulation validation must include quorum verification (e.g., ≥66% DAO simulation node review), cryptographic checkpointing, and hash-stable replay testing. Offline simulations must pass delayed revalidation on corridor reentry, with simulations timestamped and encrypted during dormancy.

4.4.10 Simulation outputs must also be validated against treaty-compliant standards and governance indicators. Nexus DSS must run an overlay audit linking simulation outcomes to SDG indicators, UN observatory metrics, or spatial finance criteria. Any outputs influencing public policy or emergency alerts must be flagged for priority review.

4.4.11 Each contributor’s simulation operations (SimOps) score must track their validation throughput, repeatability accuracy, successful SVL completions, and collaborative DAG maintenance. SimOps scores contribute to bounty eligibility, track promotions, and DAO delegate weighting.

4.4.12 Collusion and simulation fraud detection logic must operate on all peer-reviewed simulations. Nexus DSS must maintain a history of peer review nodes, voting behavior, and DAG alignment to detect suspicious validation clusters. Anomalies are logged, and if detected across three cycles, a redline arbitration is automatically opened.

4.4.13 Fellows must include simulation validation summaries in their public impact portfolio. These summaries must present digestible metadata for non-technical reviewers, including how their simulations influence risk assessments, treaty scenarios, or bioregional forecasts.

4.4.14 SVLs must include rollback annotations, simulation age, and expiration flags. Every simulation has a maximum validity duration (e.g., 12 months or until corridor baseline shifts). Old simulations must be either archived or revalidated for continued governance use.

4.4.15 Where simulations trigger payment events (e.g., bounty unlocks, grant release, or DAO treasury disbursement), they must pass enhanced validation: including cross-node zkML proof matching, SDG alignment checks, and fork-divergence analysis.

4.4.16 Simulation-based funding or impact-linked payments must enter a 2-cycle escrow period post-validation. Funds are unlocked only if simulations remain undisputed and SVLs stay unamended for the full duration.

4.4.17 QR-coded access to each simulation’s reproducibility snapshot must be published in the Fellow’s GitHub repo, enabling peer reviewers and treaty observers to revalidate outputs without system login. Mobile-ready revalidation must be supported for in-field use.

4.4.18 All validation protocols must be transparent, corridor-auditable, open-source, and licensed under Nexus Commons terms. The NSF technical committee must update reference implementations every six months in accordance with corridor and treaty updates.

4.4.19 Repeat violation of simulation protocols leads to tiered enforcement: warnings, cooldown suspensions, corridor alerts, DAO exclusion, and Ethics Board investigation. All penalties must be documented and appealable via transparent DAG process.

4.4.20 Final validation outcomes must be registered with both the Nexus Transparency Ledger and applicable multilateral observability registries. Simulations related to disaster forecasts, treaty enforcement, or emergency alerts must sync to UN or World Bank-linked dashboards within 24 hours of validation.

4.5 Role Performance Dashboards, Contributor Scorecards, and Safety Indexes

4.5.1 Every Fellow participating in the Nexus Fellowship Program will have a dynamically updated performance dashboard that tracks contributions across simulation outputs, peer validations, governance participation, and cross-track collaborations. These dashboards must be standardized, corridor-specific, and globally accessible via the Nexus DSS.

4.5.2 Dashboards will include a Contributor Scorecard summarizing the following metrics: (a) Simulation Success Rate (SSR); (b) Peer Validation Accuracy (PVA); (c) Governance Engagement Index (GEI); (d) SDG Impact Linkage Ratio (SILR); (e) Conflict Resolution Participation (CRP); and (f) Timely Delivery Index (TDI).

4.5.3 Each metric must be accompanied by a weighted score based on the corridor’s risk classification and the Fellow’s declared track. A transparent algorithm for weightings must be published and updated biannually. Fellows operating in higher-risk regions or on simulations affecting multilateral frameworks receive multiplier weightings for governance sensitivity.

4.5.4 Contributor dashboards must also present a Safety Integrity Score (SIS), updated every 30 days, calculated using three core components: (i) compliance with simulation validation protocols; (ii) historical SVL revalidation integrity; and (iii) absence of redline arbitration or Ethics Board investigations. SIS audit trails must be anchored to DAO quorum logs.

4.5.5 The dashboard must provide a visual timeline showing simulation activity, validation frequency, DAO participation, and elevation markers. Timeline flags for warnings, arbitration cases, or external reviews must also be displayed for transparency.

4.5.6 All scorecards must include a Corridor Impact Index (CII), recalculated every 60 days. CII reflects how a Fellow’s outputs have influenced local governance, disaster risk reduction, emergency simulations, and SDG progress. Metrics must be linked to observability systems such as UNDRR dashboards, World Bank climate models, or Nexus Impact Registries.

4.5.7 Contributor dashboards must log the full history of peer reviews issued and received. Reviewer credibility scores must be calculated based on long-term alignment with validated simulations, review consistency, and diversity of domain engagement.

4.5.8 The Nexus DSS must maintain real-time syncing of scorecard entries with GitHub and Zenodo. Any submission linked to a deliverable repository must automatically populate the Fellow’s dashboard, complete with RDF metadata, SPDX license tags, and simulation checkpoint hashes.

4.5.9 Dashboards must clarify whether feedback came from automated observability engines, peer contributors, DAO stewards, or corridor-specific councils. Attribution chains must be clear, timestamped, and linked to Git logs and impact chains.

4.5.10 Contributor dashboards must support redemption logic for flagged Fellows. This includes: (a) two clean simulation cycles, (b) three peer-approved contributions, and (c) one governance mentoring action. Once met, soft-locks are lifted and scores restored gradually.

4.5.11 All dashboards must support a privacy layer, allowing contributors to set access permissions—e.g., public, DAO-only, or peer-specific—for each section of the scorecard, complying with GDPR-like protocols. Retention policies must be configurable by region.

4.5.12 All performance dashboards and scorecards must be available in offline mode for Fellows working in disconnected corridors. Offline data sync must occur within 72 hours of restored connectivity and be validated by corridor-linked DAO stewards.

4.5.13 The NSF must publish a Fellowship Governance Almanac quarterly, summarizing anonymized role performance distributions, DAO impact zones, corridor safety trends, and scorecard evolution analytics. The Almanac must be FAIR-compliant and published on Zenodo with RDF indexing.

4.5.14 Role transitions (e.g., Fellow → Steward → Architect) must be directly linked to dashboard metrics. Minimum thresholds must be declared, and elevation disputes resolved through simulation-based peer arbitration.

4.5.15 Simulation DAGs, once validated, must include a metadata pointer to the contributor’s scorecard snapshot at time of approval, enabling future traceability of decision provenance and contributor integrity.

4.5.16 Score manipulation, whether by DAG collusion, self-validation attempts, or gaming of quorum patterns, results in immediate suspension, CRL flagging, and referral to the Ethics Board. Reinstatement requires DAO-supervised review.

4.5.17 Each contributor’s dashboard must feature a simulation-driven Reputation Ledger (SRL), which integrates their simulation trustworthiness, team conduct, DAO voting record, and resilience under corridor stress scenarios. SRLs are recalculated quarterly.

4.5.18 Performance dashboards must allow contributors to compare their indicators against anonymized corridor-wide benchmarks and DAO medians. Optional overlays may include trends, percentile rankings, and track-specific guidance.

4.5.19 Contributor dashboards must be cryptographically signed, hash-anchored in the Nexus Transparency Ledger, and optionally open to peer review and governance councils. Contributors are notified of any updates or rule changes within 24 hours.

4.5.20 All performance dashboards must be clause-anchored, RDF-indexed, simulation-linked, and version-controlled by NSF. Appeal rights, audit logs, elevation eligibility, and resilience metrics must be clearly visible to the contributor at all times.

4.6 Evidence-Based Code, Media, and Simulation Impact Indexes

4.6.1 All contributor outputs—whether software, media, simulations, or models—must include clear, evidence-based impact documentation submitted alongside the primary deliverable. This documentation must show the intended impact, use case relevance, and linkage to Nexus Indicators, SDG targets, or community needs.

4.6.2 GitHub repositories must include an impact.md file outlining measurable outcomes for each version release, structured around use-case scenarios, adoption metrics, governance outputs, or downstream integrations. Markdown templates must be provided for consistency.

4.6.3 Media outputs (e.g., video explainers, simulations, storytelling formats) must submit an impact.json summary logged in the GRF Media Repository, including audience size, engagement indicators, reuse under Nexus Commons Licensing, and policy integration references if applicable.

4.6.4 All simulations submitted by Fellows must be accompanied by an impact.rdf file referencing the originating simulation DAG, validation history, corridor use case, and expected deployment readiness. RDF files must be FAIR-compliant and linked via Zenodo DOI anchors.

4.6.5 A Simulation Impact Score (SIS) must be calculated for every submission, combining (a) corridor-level significance, (b) governance validation reuse, (c) peer adoption metrics, and (d) simulation reproducibility index. SIS must be integrated into the contributor dashboard.

4.6.6 A Nexus Impact Registry (NIR) must track all evidence-linked outputs and their downstream effects across corridors, treaties, multilateral dashboards, and scientific institutions. Each entry must be hash-anchored and DAO-approved.

4.6.7 Each submission's metadata must specify the type of evidence used to support claims: (a) primary research; (b) peer-reviewed benchmarks; (c) treaty-aligned impact validators (e.g., SDG Labs, UNDRR); or (d) simulation forecast backtests.

4.6.8 Impact indexes must include role-specific contribution labels—e.g., authored, reviewed, simulated, integrated—with clear credit weights. These weights feed into the contributor’s Governance Elevation Score and Reputation Ledger.

4.6.9 Where applicable, institutional validation statements from labs, think tanks, city pilots, or public agencies must be appended as impact validators. These validate the simulation's real-world influence and feed back into track-specific metrics.

4.6.10 A public-facing Nexus Impact Browser must be maintained to allow Fellows, partners, and governance councils to view impact-indexed submissions, cross-track aggregates, and evolution analytics. All impact data must be exportable in RDF, CSV, and SPDX-tagged reports.

4.6.11 Fellows are required to update their impact files at least once per quarter or upon major version releases. Failure to maintain impact records may result in soft flagging within the DAO observability pipeline and temporary lock on new submissions.

4.6.12 Evidence-based indexes must support multilingual metadata entries to enable equitable accessibility across Nexus corridors and communities. Minimum metadata must be provided in English, French, Spanish, and the relevant corridor-native language.

4.6.13 DAO reviewers must validate impact documentation during the approval phase using simulation-linked audit criteria. Discrepancies between declared and observed impact may result in mandatory corrections or reputation score adjustments.

4.6.14 All Nexus Impact Index entries must be clause-anchored to the source submission’s license, contribution role, and simulation forecast. This allows clear audit trails for retrospective governance or dispute resolution.

4.6.15 Fellows with repeated high-impact submissions will receive an Impact Contributor Distinction (ICD) visible on their profile, dashboards, and eligibility matrix for cross-track leadership opportunities or multilateral fellowships.

4.6.16 Impact indexes must be version-controlled and time-stamped with GitHub release tags, Zenodo DOIs, and RDF metadata signatures. Submissions without these compliance anchors cannot be approved for corridor deployment.

4.6.17 GRF and GRA must publish biannual Nexus Impact Reports summarizing corridor-linked performance, simulation influence, treaty validation uptake, and evidence-based governance progress. These reports must be deposited in Zenodo and accessible from the DSS.

4.6.18 Fellows may appeal negative or disputed impact scores by initiating a Simulation Impact Reassessment (SIR) protocol. DAO-led peer panels must resolve SIRs within 30 days and document findings in the Nexus Impact Browser.

4.6.19 Simulations or codebases flagged for overclaiming impact may require revalidation DAG cycles and additional proof-of-impact deliverables. These must be clearly labeled and reviewed by corridor-specific governance reviewers.

4.6.20 All evidence-based indexes and impact metadata must comply with Nexus Commons Licensing, FAIR principles, RDF discoverability, and NSF certification audits.

4.7 Institutional Integration: Labs, Think Tanks, Local City Pilots

4.7.1 All Fellowship tracks must establish structured collaboration pathways with recognized institutions, including academic laboratories, applied research institutes, municipal governance units, innovation accelerators, and nonprofit development agencies. These partnerships are essential for validating Fellowship outputs, enabling live simulation deployments, and ensuring public relevance and community benefit.

4.7.2 All institutional partnerships must be approved and verified by the Nexus Standards Foundation (NSF), which maintains a compliance framework aligned with multilateral treaties, SDG Labs, Horizon Europe standards, World Bank Urban Resilience initiatives, and national or provincial research councils. Institutions must complete an onboarding form and adhere to corridor-specific ethical and operational standards.

4.7.3 Fellows must map their deliverables to at least one eligible institutional node per project. Deliverables may include codebases, simulations, scenario pilots, policy briefs, or media outputs. Mappings must be registered in the Simulation Deployment Ledger (SDL) with RDF-based linkage.

4.7.4 Simulation DAGs tested within institutional pilots must be cryptographically co-signed by both the designated corridor validator and the institutional lead. These signatures must be published in the Nexus Simulation Ledger to ensure transparency and auditability of all pilot trials.

4.7.5 Each institutional engagement must result in a signed Memorandum of Simulation Deployment (MoSD), which defines project objectives, corridor and partner responsibilities, key performance indicators (KPIs), risk level, evaluation method, and expected simulation duration. The MoSD must be logged in the DSS and submitted to NSF for archival.

4.7.6 Partners including think tanks and municipalities may issue formal Impact Validation Reports (IVRs) assessing outcomes such as policy relevance, simulation fidelity, SDG linkage, risk mitigation efficacy, and stakeholder engagement levels. These reports must be uploaded to the Nexus Impact Registry and are incorporated into the contributor’s dashboard.

4.7.7 Fellows involved in multiquarter partnerships must hold milestone reviews every 90 days, co-chaired by their corridor steward and the institutional liaison. Reviews must follow a standard report format, include a simulation revalidation, and be uploaded to the Governance DAG.

4.7.8 Fellows deployed at institutional sites must adhere to residency ethics, nonpartisan engagement, and safety compliance. These include community interaction boundaries, nondisruption of public services, and data governance restrictions. Fellows must complete a pre-deployment training and ethics clearance.

4.7.9 Institutional partners are encouraged to nominate Fellows for governance elevation based on successful simulations, public impact, or policy integration. Nominations are reviewed quarterly by the DAO Ethics Council and can trigger pathway transitions to Steward or Architect status.

4.7.10 NSF shall maintain a live public index of all verified institutional nodes. Each listing will include thematic areas, approved simulation domains, sandbox capacities, contact liaisons, language preferences, corridor geotag, risk tiering, and license requirements.

4.7.11 The Simulation Deployment Ledger (SDL) shall record all institutional engagements across corridors, simulation types, and timeframes. Each entry will reference the corresponding DAG ID, contributor ID, simulation outputs, impact scores, and DAO status.

4.7.12 Governance simulations with potential regulatory impact must undergo a three-layer institutional review including: (i) the host institution’s advisory panel; (ii) corridor-specific DAO validators; and (iii) the NSF’s Multilateral Policy Review Hub. Final approval must include all three tiers.

4.7.13 Simulations involving human subjects, critical public infrastructure, or politically sensitive datasets must undergo IRB-level ethical review. This includes community notice, consent logs, anonymization protocols, and fallback scenarios in case of system stress.

4.7.14 Fellows must integrate participatory design and citizen feedback into simulation workstreams. Minimum requirements include stakeholder interviews, participatory workshops, and civic feedback sessions before final validation. These sessions must be recorded and linked to deliverables.

4.7.15 A formal Nexus Lab Residency Protocol will be enacted for all institutional deployments, specifying shared IP rights, field simulation limitations, corridor safety norms, redline clauses, dispute channels, and withdrawal conditions. All participating Fellows and institutions must sign the protocol.

4.7.16 All outputs derived from institutional partnerships must be licensed under Nexus Commons terms, SPDX-tagged, and submitted to Zenodo, GitHub, or the GRF Repository, depending on the track. Attribution must follow RDF-compliant logic and include contributor, institutional, and validator roles.

4.7.17 Any legal or operational dispute arising from institutional collaborations must be escalated to the Fellowship Arbitration DAG and resolved within 30 calendar days. Emergency override provisions may be enacted if public safety or IP violations are involved.

4.7.18 City pilots demonstrating recurring simulation impact, high-value governance outcomes, or treaty-aligned validation must be added to the Nexus Permanent Sandbox Registry. These pilots offer continuous access for scenario testing, corridor training, and public consultation.

4.7.19 Fellows and partner institutions may jointly publish results in policy dashboards, simulation impact reviews, academic journals, or treaty platforms. All co-publications must follow clause certification, include DAG references, and follow Nexus Impact Report protocols.

4.7.20 All institutional partnerships must be clause-audited, corridor-verified, license-compliant, and governance-anchored. NSF reserves the right to suspend partnerships that violate ethics protocols, misuse DAG simulations, or deviate from Fellowship safety standards.

4.8 Zero-Trust Infrastructure, CI/CD Pipelines, DAG Fork Handling

4.8.1 All technical workflows within the Fellowship program shall operate on a zero-trust architecture. Contributors must authenticate every access session through zkID and sign all commits, simulations, or configuration changes using clause-certified credentials.

4.8.2 Continuous Integration and Continuous Deployment (CI/CD) pipelines must be implemented for all code, policy, and simulation outputs. These pipelines must include automated syntax validation, simulation test execution, and metadata compliance checks prior to DAG anchoring.

4.8.3 CI/CD workflows must be hosted on open-source compatible platforms (e.g., GitHub Actions, GitLab CI/CD) with logs indexed in the Fellowship Observability Ledger. All jobs must include digital proofs of execution integrity, linked to the contributor’s role dashboard.

4.8.4 Each deployment event must trigger simulation reproducibility tests. Failing simulations must be automatically flagged in the contributor’s scorecard with reasons for rejection and a cooldown timer before resubmission.

4.8.5 Fellowship pipelines must support rollback mechanisms. Each CI/CD cycle must generate signed deployment snapshots and hash-anchored rollback packages to restore trusted last-known states under corridor-defined recovery logic.

4.8.6 All DAG forks—created for testing, revision, or dispute resolution—must be registered in the Nexus Fork Registry (NFR). Each fork must include metadata describing rationale, originating DAG lineage, linked contributors, and resolution pathways.

4.8.7 Forked DAGs must not be promoted to production or governance unless explicitly approved by corridor validators and audited by NSF. Promotion conditions include simulation integrity review, conflict reconciliation, and rollback validation.

4.8.8 Zero-trust policies must extend to inter-module communication across NXS-DSS, NXS-AAP, and NXSCore. Each module must verify simulation lineage, user privileges, and clause conformance before accepting DAG inputs or triggering actuation.

4.8.9 Contributors must not rebase or overwrite governance-affecting DAGs without quorum-based multisig approvals recorded on the Simulation Governance Ledger. Unauthorized rebase attempts shall trigger an ethics investigation.

4.8.10 Offline-ready backups of CI/CD logs, DAG snapshots, and simulation outputs must be maintained by NSF for emergency simulation mode activation. These backups must support verifiable cold restore within corridor timelines.

4.8.11 Fork handling procedures must include a mandatory post-fork review protocol. Contributors initiating a fork must file a Fork Resolution Form (FRF) with justifications, proposed reconciliation logic, and a snapshot of stakeholder impact.

4.8.12 All fork-related disputes must be routed through the DAG Arbitration Engine and resolved within 15 calendar days. Emergency forks—triggered during corridor collapse or political shutdowns—must be documented and reviewed under GRF emergency override conditions.

4.11.28 Contributors must acknowledge their simulation's anchoring status and corridor assignment prior to DAG commit. Unanchored simulations during active alerts are automatically flagged and frozen.

4.11.29 Emergency simulations must include a clause-driven debrief window, typically 30–60 days post-crisis, in which contributor logs, simulation decisions, and digital twin overlays are reviewed by GRF-Emergency Council.

4.11.30 Simulation outputs generated in ESM must be interoperable with city-level Digital Twin pilots, corridor UN SDG maps, and NSF observability dashboards.

4.11.31 If ESM-generated results diverge critically from expected scenarios, the DAG must trigger the Emergency Override Protocol (EOP), which can enforce corrective policy simulations or freeze further action until resolution.

4.11.32 All Digital Twin Anchors must be mirrored across redundant observability nodes in at least two geographic corridors to ensure disaster survivability and ensure compliance with sovereign resilience standards.
