PVEP Governance Kernel Integration

1. Purpose

The PVEP Governance Kernel Integration defines how the ProductVerse Experience Plane (PVEP) integrates with the Governance Kernel to render governance-aware product experiences across the ProductVerse.

PVEP is the consumer-oriented experience plane. It helps humans, organizations, applications, agents, and products-as-consumers discover, evaluate, acquire, consume, navigate, trust, select, and prepare products.

The Governance Kernel is the computational governance core. It evaluates policy, entitlement, trust, risk, evidence, DPP, lifecycle, relationship, and runtime context.

This document explains how PVEP should consume Governance Kernel state, decisions, signals, interfaces, and explanations without becoming the governance authority itself.

The key principle is:

PVEP renders governance state. The Governance Kernel computes and assures governance state. Product Fabric enforces governance state where runtime enforcement is required.

---

2. Core Integration Statement

The integration can be summarized as:

PVEP asks:
  What should this actor be allowed to see, do, understand, request, consume, select, or trust?

Governance Kernel answers:
  What governance state, decision, constraint, obligation, explanation, signal, or next action applies?

PVEP renders:
  A human- and agent-usable experience based on that kernel-derived state.

In short:

Governance Kernel = governance computation and assurance
PVEP              = governance-aware experience mediation

PVEP must not manually interpret policy, invent entitlement, create trust badges, override risk, or fabricate evidence state.

---

3. Why Integration Is Needed

Without Governance Kernel integration, PVEP would risk becoming a decorative governance surface.

That would create problems such as:

• products shown as trusted without evidence,
• access buttons shown without entitlement,
• products recommended despite prohibited purpose,
• DPP warnings ignored or stale,
• risk shown as a static label,
• agents acting without authority checks,
• selected product sets hiding inherited restrictions,
• marketplace acquisition shown as equivalent to usable entitlement,
• product graph navigation exposing relationships the user should not infer,
• consumption actions displayed even when runtime enforcement would block them.

The Governance Kernel gives PVEP authoritative governance state.

PVEP makes that state visible, understandable, actionable, and context-sensitive.

---

4. Integration Scope

PVEP should integrate with the Governance Kernel across all major PVEP experience zones.

PVEP zone	Governance Kernel integration
Marketplace Experience Zone	Listing eligibility, trust, DPP, license, pricing eligibility, acquisition eligibility, permitted-use state.
Consumption Experience Zone	Runtime eligibility, output-port permission, usage constraints, entitlement, trust, risk, audit obligations.
Concierge & Agent-Mediated Discovery Zone	Intent-aware recommendations, agent authority, product suitability, trust-aware ranking, policy-aware filtering.
Product Graph Navigation Zone	Governance-aware graph overlays, policy edges, trust edges, entitlement edges, risk overlays, hidden relationship protection.
Portfolio & Entitlement Experience Zone	Entitlement state, subscription state, license state, delegated authority, output-port access, expiry, revocation.
Product Select & Assembly Zone	Product set suitability, inherited restrictions, composition warnings, PDEP handoff readiness.
Governance & Trust Experience Zone	Trust, risk, evidence, DPP, policy, entitlement, lifecycle, exception, and assurance views.

The integration should support both human-facing and machine-readable experiences.

---

5. Governance State Consumed by PVEP

PVEP may consume several categories of Governance Kernel state.

5.1 Policy State

Policy state tells PVEP what uses are allowed, restricted, prohibited, conditional, or subject to obligations.

Examples:

Internal analytics allowed.
External sharing prohibited.
API access requires approval.
Human review required for automated decisioning.

5.2 Entitlement State

Entitlement state tells PVEP what the actor may do.

Examples:

User is entitled to dashboard access.
User is not entitled to SQL endpoint.
Agent may recommend but may not acquire.
Product may consume Product B internally.

5.3 Trust State

Trust state tells PVEP whether a product, output port, relationship, or product set is fit for reliance in context.

Examples:

Trusted for internal reporting.
Conditionally trusted for regulatory reporting.
Not trusted for external redistribution.
Trust under review because evidence expired.

5.4 Risk State

Risk state tells PVEP what risk posture applies and what controls are required.

Examples:

Risk tier R3.
Human review required.
Escalation required for autonomous use.
Runtime monitoring required.

5.5 Evidence State

Evidence state tells PVEP whether required evidence exists and is sufficient.

Examples:

Quality evidence current.
Lineage evidence incomplete.
Rights evidence missing.
Safety certification expired.

5.6 DPP State

DPP state tells PVEP the status and suitability of the Digital Product Passport.

Examples:

DPP valid.
DPP incomplete.
DPP expired.
DPP version mismatch.
DPP valid for internal use but not external distribution.

5.7 Lifecycle State

Lifecycle state tells PVEP the governed product lifecycle status.

Examples:

Published.
Deprecated.
Retired.
Under review.
Publication blocked.
Recertification required.

5.8 Relationship Governance State

Relationship governance state tells PVEP how product relationships should be rendered.

Examples:

Product inherits no-external-sharing restriction.
Selected product set has license conflict.
Dependency is deprecated.
Product-to-product entitlement missing.

---

6. Core Integration Interfaces

PVEP may consume several Governance Kernel interfaces.

PVEP
├─ Decision Interface
├─ Entitlement Interface
├─ Policy Explanation Interface
├─ Trust Interface
├─ Risk Interface
├─ Evidence Interface
├─ DPP Interface
├─ Lifecycle State Interface
├─ Relationship Governance Interface
├─ Signal Subscription Interface
├─ Explanation Interface
└─ Audit Summary Interface

PVEP should use structured Governance Kernel responses rather than free-text or locally hardcoded governance logic.

---

7. Decision Interface Integration

PVEP uses the Decision Interface when a user or agent attempts a governed action.

Examples:

• open product,
• request access,
• subscribe,
• invoke output port,
• download file,
• share externally,
• add product to product set,
• recommend product,
• transition to PDEP,
• inspect restricted evidence.

Example request:

decisionRequest:
  subject:
    id: user-123
    type: human-user

  action: invoke-output-port

  product:
    id: product-456
    version: 2.1

  outputPort:
    id: dashboard-port

  purpose:
    code: internal-analytics

  context:
    environment: production

Example response:

decision:
  outcome: conditional-allow
  constraints:
    - no-external-sharing
    - audit-logging-required
  explanation:
    summary: >
      Dashboard use is allowed for internal analytics.
      External sharing is not permitted.

PVEP renders this as an available action with visible constraints.

---

8. Entitlement Interface Integration

PVEP uses entitlement interfaces to show whether actors can access or use products.

It may use this state in:

• product cards,
• portfolio views,
• marketplace listings,
• output-port panels,
• access request flows,
• product set suitability checks,
• agent authority displays.

Example PVEP rendering:

Dashboard: Available
API: Approval required
File download: Not entitled
DPP summary: Viewable
Evidence detail: Restricted

PVEP should avoid reducing entitlement to a single “has access” flag.

---

9. Policy Explanation Interface Integration

PVEP uses policy explanation interfaces to show permitted and prohibited uses.

Example rendering:

Allowed:
- Internal analytics
- Dashboard viewing

Restricted:
- API access requires approval

Prohibited:
- External sharing
- File download

Policy explanations should be:

• audience-appropriate,
• concise by default,
• inspectable in detail,
• linked to next actions,
• derived from Governance Kernel state.

---

10. Trust Interface Integration

PVEP uses trust interfaces to display product trust posture.

Example rendering:

Trusted for internal analytics.
Conditionally trusted for regulatory reporting.
Not trusted for external sharing.

Trust integration should include:

• product version,
• purpose,
• output port,
• evidence summary,
• DPP state,
• risk state,
• restrictions,
• review date.

PVEP should not show a global “trusted” badge without context.

---

11. Risk Interface Integration

PVEP uses risk interfaces to display risk posture and required controls.

Example rendering:

Risk tier: R3 — High Risk

Reason:
This AI Product may materially influence operational decisions.

Required controls:
- Human review
- Audit logging
- Monitoring

Risk state should guide:

• warnings,
• approval flows,
• product suitability,
• agent recommendations,
• PDEP handoff,
• output-port availability,
• consumption constraints.

---

12. Evidence Interface Integration

PVEP uses evidence interfaces to display evidence state and evidence gaps.

Example rendering:

Claim:
Approved for regulatory reporting.

Evidence:
- Quality report: current
- Lineage record: incomplete
- Steward approval: current

Result:
Partially supported.

PVEP should render evidence as claim-bound assurance, not as a dump of documents.

---

13. DPP Interface Integration

PVEP uses DPP interfaces to display DPP state.

Example rendering:

DPP valid for Product v2.1.
Evidence supports internal use.
External redistribution evidence is missing.
Next DPP review: 2026-12-31.

DPP integration is used across:

• marketplace listings,
• product detail pages,
• Governance & Trust zone,
• Product Graph overlays,
• product set suitability,
• PDEP handoff previews,
• agent-readable product evaluation.

PVEP should distinguish:

DPP present
DPP complete
DPP valid
DPP suitable for this purpose

These are not the same.

---

14. Lifecycle State Interface Integration

PVEP uses lifecycle state interfaces to display product status.

Examples:

• active,
• published,
• deprecated,
• retired,
• under review,
• blocked,
• recertification required.

Example rendering:

This product is deprecated and will be retired on 2026-12-31.
Recommended substitute: Product B.

Lifecycle state may affect:

• marketplace visibility,
• consumption availability,
• product set suitability,
• portfolio health,
• graph navigation,
• PDEP transition.

---

15. Relationship Governance Interface Integration

PVEP uses relationship governance interfaces to show product-to-product governance context.

Examples:

This product depends on a deprecated product.
This product inherits a no-external-sharing restriction.
This selected product set has conflicting licenses.
This product-to-product entitlement is missing.

This integration is especially important for:

• Product Graph Navigation Zone,
• Product Select & Assembly Zone,
• Governance & Trust Experience Zone,
• PDEP handoff preview.

---

16. Signal Subscription Integration

PVEP should subscribe to Governance Kernel signals to keep experiences fresh.

Relevant signal types include:

• entitlement revoked,
• entitlement expired,
• DPP expired,
• evidence expired,
• trust downgraded,
• trust upgraded,
• risk tier changed,
• policy updated,
• product deprecated,
• product retired,
• output port disabled,
• exception expired,
• agent authority expired,
• lifecycle state changed.

Example signal handling:

Signal:
DPP_EXPIRED

PVEP effects:
- update product trust badge,
- show DPP warning,
- disable external-use action if required,
- notify steward where appropriate,
- refresh product listing governance summary.

Signals help prevent stale governance displays.

---

17. Explanation Interface Integration

PVEP should use explanation interfaces to render human- and agent-usable reasons.

Example consumer explanation:

You can use this product for internal analytics because your team has an active entitlement.
External sharing is not allowed because the product license prohibits redistribution.

Example agent-readable explanation:

outcome: conditional-allow
reasonCodes:
  - ENTITLEMENT_ACTIVE
  - EXTERNAL_SHARING_PROHIBITED
constraints:
  - no-external-sharing
  - audit-logging-required

PVEP should support progressive disclosure:

summary → reason → evidence → policy trace → audit detail

---

18. Audit Summary Interface Integration

PVEP may render audit summaries where appropriate.

Examples:

• access request history,
• entitlement approval history,
• DPP review history,
• trust timeline,
• risk review status,
• lifecycle transition history,
• evidence update history.

PVEP should not expose full audit detail to unauthorized users.

---

19. Common PVEP Governance Request Context

PVEP should send rich context to the Governance Kernel.

A common context may include:

subject:
  id: subject-id
  type: human-user | organization | application | machine-agent | ai-agent | institutional-agent | product

action: action-code

product:
  id: product-id
  kind: product-kind
  version: product-version

outputPort:
  id: output-port-id
  type: output-port-type

purpose:
  code: purpose-code
  declaredBy: subject | system | inferred

context:
  environment: marketplace | sandbox | production | external | mission-critical
  jurisdiction: jurisdiction-code
  time: timestamp

relationshipContext:
  relationshipType: consumes | depends-on | composed-from | substitute-for | selected-with
  downstreamUse: downstream-use-code

Not every request requires all fields, but high-impact decisions should provide enough context to avoid weak outcomes.

---

20. Common PVEP Governance Response

PVEP should expect structured governance responses.

Example:

governanceResponse:
  outcome: conditional-allow

  state:
    policyState: restricted
    entitlementState: entitled
    trustState: conditionally-trusted
    riskState: R2
    evidenceState: current
    dppState: valid

  constraints:
    - no-external-sharing
    - audit-logging-required

  obligations:
    - display-dpp-summary

  explanation:
    summary: >
      Use is allowed for internal analytics.
      External sharing is prohibited.
    reasonCodes:
      - INTERNAL_USE_ALLOWED
      - EXTERNAL_SHARING_PROHIBITED

  nextActions:
    - open-dashboard
    - request-api-approval

  audit:
    traceId: trace-001
    evaluatedAt: 2026-05-19T10:00:00Z

PVEP should translate this response into user-facing or agent-facing experience states.

---

21. Rendering Patterns

PVEP may render Governance Kernel state through several patterns.

21.1 Action Availability Pattern

Shows actions as available, disabled, hidden, pending, or requiring approval.

Examples:

• Open dashboard,
• Request API access,
• Accept license,
• Subscribe,
• View DPP,
• Add to product set,
• Transition to PDEP.

21.2 Governance Badge Pattern

Compact state indicator.

Examples:

• DPP valid,
• trusted,
• approval required,
• high risk,
• evidence expired,
• restricted use.

Badges must be backed by kernel state and link to explanation.

21.3 Warning Banner Pattern

Used for important governance conditions.

Example:

This product is under trust review. External use is temporarily unavailable.

21.4 Explanation Drawer Pattern

Provides deeper reasoning without overwhelming the main page.

21.5 Governance Detail View Pattern

Used for DPP, trust, evidence, policy, risk, and lifecycle inspection.

21.6 Product Set Suitability Pattern

Summarizes governance readiness of selected products.

21.7 Agent-Readable Response Pattern

Returns structured constraints, reason codes, and next actions for agents.

• DPP summary,
• permitted uses,
• prohibited uses,
• license constraints,
• subscription eligibility,
• acquisition requirements,
• approval requirements,
• risk warnings.

22.2 Consumption Experience Zone

• risk-aware suggestions,
• agent authority validation,
• recommendation explanations.

22.4 Product Graph Navigation Zone

Uses Governance Kernel state to render:

• policy edges,
• entitlement edges,
• trust edges,
• risk overlays,
• evidence edges,
• DPP relationships,
• inherited restrictions,
• visibility-limited graph views.

22.5 Portfolio & Entitlement Experience Zone

Uses Governance Kernel state to render:

• active entitlements,
• pending access,
• subscriptions,
• license status,
• delegated authority,
• output-port access,
• product-to-product entitlement,
• expiry and revocation.

22.6 Product Select & Assembly Zone

Uses Governance Kernel state to render:

• product set suitability,
• inherited restrictions,
• missing entitlements,
• trust gaps,
• risk amplification,
• DPP gaps,
• evidence gaps,
• PDEP handoff readiness.

22.7 Governance & Trust Experience Zone

Uses Governance Kernel state to render:

• trust posture,
• DPP detail,
• evidence summary,
• policy explanation,
• risk explanation,
• entitlement-aware trust,
• product set trust,
• trust timeline.

---

23. Visibility and Access Control

PVEP must respect governance visibility.

Governance state may reveal sensitive information, including:

• restricted evidence,
• hidden products,
• confidential relationships,
• internal policies,
• risk logic,
• entitlement details,
• agent authority records,
• audit traces,
• exception records.

PVEP should ask the Governance Kernel for audience-appropriate views.

Examples:

Public summary
Consumer summary
Steward detail
Governance detail
Auditor trace
Agent-readable view

PVEP should not leak restricted information through error messages, badges, graph views, search results, warnings, or recommendations.

---

24. Caching and Freshness

PVEP may cache governance summaries for responsiveness, but must not create stale governance experiences.

Cacheable with care:

• product DPP summary,
• trust summary,
• policy summary,
• marketplace listing governance summary,
• risk summary.

Requires stricter freshness:

• entitlement state,
• revocation state,
• agent authority,
• runtime decisions,
• DPP expiry,
• evidence expiry,
• high-risk changes,
• policy violations.

PVEP should invalidate or refresh cached state when Governance Kernel signals indicate change.

Principle:

A stale governance display can become a false governance display.

---

25. Error Handling

PVEP should handle Governance Kernel errors carefully.

Possible conditions:

• insufficient context,
• governance service unavailable,
• policy conflict,
• evidence not visible,
• entitlement unknown,
• DPP evaluation pending,
• signal delay,
• audit unavailable,
• runtime decision timeout.

PVEP should avoid unsafe defaults.

Example handling:

Governance state could not be verified.
This action is unavailable until verification completes.

For low-risk informational views, PVEP may show stale-but-marked summaries if permitted.

For high-risk or runtime actions, failure to verify should usually block or require review.

---

26. Agent Integration

Agents need structured Governance Kernel state.

PVEP should support agent integration by providing:

• machine-readable decisions,
• permitted actions,
• prohibited actions,
• constraints,
• obligations,
• reason codes,
• DPP summaries,
• trust state,
• risk state,
• entitlement state,
• next actions,
• human confirmation requirements.

Example:

agentGovernanceView:
  action: recommend-product
  outcome: allow
  constraints:
    - recommendation-only
    - no-acquisition-without-human-confirmation
  reasonCodes:
    - AGENT_DELEGATION_VALID
    - ACQUISITION_REQUIRES_HUMAN

Agents should not infer permission from UI visibility alone.

---

27. Product Graph Integration

PVEP Product Graph views must be governance-aware.

The Governance Kernel may determine:

• which nodes are visible,
• which edges are visible,
• which relationships are restricted,
• which trust overlays apply,
• which risk overlays apply,
• which dependencies are hidden,
• which evidence relationships can be shown,
• whether graph traversal reveals restricted information.

Graph navigation should avoid inference leaks.

Example:

User may see that Product A has a restricted dependency,
but not the identity of the restricted dependency.

---

28. PDEP Handoff Integration

When PVEP transitions to PDEP, it should include Governance Kernel state in the handoff.

The handoff may include:

• selected products,
• product versions,
• intended purpose,
• actor or creator context,
• entitlement state,
• policy constraints,
• inherited restrictions,
• trust state,
• risk state,
• evidence gaps,
• DPP state,
• license constraints,
• relationship governance,
• agent involvement,
• recommended next actions.

This prevents PDEP from losing important governance context.

---

29. Observability

PVEP should emit observability events about governance experience usage.

Examples:

• governance badge viewed,
• DPP summary opened,
• trust detail viewed,
• policy explanation viewed,
• risk warning shown,
• access request started,
• entitlement denial shown,
• product blocked due to governance,
• product set suitability checked,
• PDEP handoff initiated,
• agent recommendation constrained by governance,
• user ignored warning,
• substitute selected due to trust downgrade.

These events help improve governance usability and ProductVerse health.

---

30. Security Considerations

PVEP Governance Kernel integration should protect sensitive state.

Controls include:

• authenticated calls to kernel interfaces,
• subject-aware authorization,
• audience-specific responses,
• minimization of governance detail,
• secure handling of evidence references,
• prevention of inference leakage,
• secure signal consumption,
• secure caching,
• audit logging for sensitive views,
• protection of agent-readable governance responses,
• safe fallback behavior.

---

31. Design Guidance

31.1 Render Kernel State, Do Not Recreate It

PVEP should not implement policy, entitlement, trust, risk, or DPP logic locally.

31.2 Ask with Context

PVEP should provide actor, product, purpose, output port, environment, and relationship context.

31.3 Make Governance Understandable

Render decision state in plain language, with progressive detail.

31.4 Keep Experiences Actionable

Every block, warning, or restriction should guide next action where possible.

31.5 Support Human and Agent Consumers

Humans need understandable explanations. Agents need structured governance responses.

31.6 Keep Trust Evidence-Backed

Trust badges and DPP views should link to evidence where permitted.

31.7 Respect Visibility

Do not reveal sensitive governance information to unauthorized actors.

31.8 Listen to Signals

PVEP should update governance views when kernel signals indicate state changes.

31.9 Preserve PDEP Boundary

Governance-aware selection in PVEP must not become product creation.

---

32. Anti-Patterns

32.1 Local Governance Logic in PVEP

Hardcoding policy or entitlement rules in the experience layer creates inconsistency.

32.2 Decorative Trust Badges

Badges without kernel-backed state mislead consumers.

32.3 Binary Access Display

“Has access” is too weak for output-port, purpose, time, policy, and risk-aware governance.

32.4 Stale Governance Views

Showing expired trust, entitlement, or DPP state is dangerous.

32.5 Hidden Reasoning

Users and agents need explanations, not opaque blocks.

32.6 Overexposed Governance Detail

PVEP should not reveal restricted evidence, hidden relationships, or internal policy logic.

32.7 UI-Only Enforcement

Disabling actions in PVEP is not sufficient. Product Fabric must enforce runtime decisions.

32.8 Agent Permissions by Visibility

Just because an agent can see a product does not mean it can recommend, invoke, acquire, or compose it.

32.9 PDEP Bypass

PVEP should not create governed products, descriptors, DPPs, or lifecycle states directly.

---

33. Summary

PVEP Governance Kernel Integration ensures that ProductVerse experiences are governance-aware, trustworthy, policy-sensitive, entitlement-aware, risk-aware, evidence-backed, and agent-compatible.

PVEP integrates with the Governance Kernel to consume:

• decisions,
• policy state,
• entitlement state,
• trust state,
• risk state,
• evidence state,
• DPP state,
• lifecycle state,
• relationship governance state,
• signals,
• explanations,
• audit summaries.

PVEP then renders this state across marketplace, consumption, discovery, graph navigation, portfolio, product selection, and governance trust experiences.

The central boundary is:

Governance Kernel computes and assures governance state.
PVEP renders governance state.
Product Fabric enforces governance state.
PDEP applies governance state during product creation.

In short:

PVEP Governance Kernel Integration turns computational governance into usable, contextual, human- and agent-readable ProductVerse experience.
