ProofLayer AI · Governance Evidence Framework

Seven pillars from governance intent to technical evidence

Developed by Data Fusion Analytics to help enterprises move from AI governance policy to platform-enforced controls with audit-ready evidence.

Framework Overview

Seven pillars around one outcome: AI Governance Proof.

AI GovernanceProof01Inventory02Identity03Lineage04Access05Quality06Evidence07Operating Model
Maturity Scale
1Ad Hoc

Undocumented, inconsistent, reactive.

Some practices exist but are not standardized.

3Defined

Documented, repeatable, partially enforced.

4Controlled

Technically enforced with monitoring.

5Auditable

Continuously auditable with evidence on demand.

PILLAR 01

AI Use Case Inventory

Complete, continuously updated registry of AI, GenAI, RAG, Copilot, and agentic systems in use across the enterprise.

3 diagnostic questions
Example Risk

Shadow AI deployed inside SaaS tools consumes regulated data without governance review.

Example Control

Automated discovery pipeline that reconciles cloud, SaaS, and code repositories against a governed AI inventory.

  • Q1.1

    Does your organization maintain a complete inventory of AI, GenAI, RAG, Copilot, and agentic systems currently in use?

    Includes shadow AI, embedded vendor features, and internally built agents.

    Evidence: Export from AI system registry, CMDB tags, procurement records.

  • Q1.2

    Are AI use cases classified by risk tier, data sensitivity, and regulatory scope?

    Aligned to internal risk taxonomy and applicable regulation (EU AI Act, NIST AI RMF).

    Evidence: Risk classification policy and per-use-case classification records.

  • Q1.3

    Is the inventory continuously updated as new AI capabilities are deployed?

    Automated discovery vs. periodic manual attestation.

    Evidence: Discovery pipeline logs, attestation cadence records.

PILLAR 02

Identity and Actor Attribution

Traceable identity from the originating human user through service principals, delegated tokens, and AI agents.

3 diagnostic questions
Example Risk

Audit logs show only the service principal — the human that triggered a sensitive AI action cannot be identified.

Example Control

End-to-end identity propagation via on-behalf-of tokens with scoped, time-bound delegation and full audit capture.

  • Q2.1

    Can your audit logs identify the original human user behind AI-triggered actions, even when service principals, APIs, or application identities are used?

    End-to-end identity propagation through agent chains and downstream systems.

    Evidence: Sample audit trail joining human identity to agent action.

  • Q2.2

    Are non-human identities (agents, service principals, API keys) inventoried and owned?

    Every workload identity has a documented owner and lifecycle.

    Evidence: Workload identity inventory with owner and rotation policy.

  • Q2.3

    Is delegated authority for AI agents scoped, time-bound, and revocable?

    Prevents agents from acting with broader privileges than the requesting user.

    Evidence: Token scoping policy, delegation logs.

PILLAR 03

Data Lineage and Traceability

End-to-end lineage from source data through transformation, vector indexing, retrieval, prompt, model, and tool call.

3 diagnostic questions
Example Risk

An AI-generated recommendation cannot be traced back to the source records or retrieval context that produced it.

Example Control

Per-inference provenance log capturing sources, retrieved chunks, prompt, model version, tools, and authorization path.

  • Q3.1

    Can AI-generated outputs be traced back to source data, retrieval context, model, prompt, tool, and authorization path?

    Full provenance for a given inference or agent action.

    Evidence: Trace record for a sample inference including retrieved chunks.

  • Q3.2

    Is lineage maintained across ingestion, transformation, vector indexing, and retrieval?

    Column-level or chunk-level lineage where applicable.

    Evidence: Lineage graph export from catalog or observability tool.

  • Q3.3

    Are model, prompt, and tool versions recorded with each inference?

    Enables reproduction and forensic review of past outputs.

    Evidence: Inference log schema and retention policy.

PILLAR 04

Access Control and Policy Enforcement

Technically enforced controls across data, models, prompts, tools, and downstream AI applications — not just documented.

3 diagnostic questions
Example Risk

A shared vector index leaks data the requesting user is not entitled to see.

Example Control

Retrieval-time entitlement filtering and deny-by-default policy engine at the AI gateway and data plane.

  • Q4.1

    Are access controls technically enforced across data, models, prompts, tools, and downstream AI applications?

    Not merely documented — enforced at the data plane and gateway.

    Evidence: Policy engine configuration, deny-by-default proof.

  • Q4.2

    Do RAG systems enforce the requesting user's data entitlements at retrieval time?

    Prevents privilege escalation via shared vector indexes.

    Evidence: Retrieval filter logic, entitlement check traces.

  • Q4.3

    Are prompt injection, tool misuse, and data exfiltration risks technically mitigated?

    Guardrails, output filtering, egress controls.

    Evidence: Guardrail policy, red-team results.

PILLAR 05

Data Quality and Observability

Schema validation, drift monitoring, and pipeline telemetry ensuring AI systems consume trustworthy, governed data.

3 diagnostic questions
Example Risk

Silent upstream schema drift degrades model accuracy for weeks before anyone notices.

Example Control

Contract tests, drift monitors, and DQ SLAs on every pipeline that feeds an AI system.

  • Q5.1

    Are data quality checks, schema validation, drift monitoring, and pipeline telemetry implemented before AI systems consume governed data?

    Prevents silent degradation of AI outputs from upstream data issues.

    Evidence: DQ dashboard, drift alert history.

  • Q5.2

    Is sensitive data classified and masked before entering training, fine-tuning, or retrieval corpora?

    Automated classification and redaction with audit.

    Evidence: Classification coverage report, redaction logs.

  • Q5.3

    Are model and agent behaviors monitored in production for accuracy, safety, and drift?

    Observability beyond infrastructure metrics.

    Evidence: Model observability dashboard, incident review records.

PILLAR 06

Audit Evidence and Compliance Readiness

Reproducible, on-demand evidence of approvals, data usage, risks reviewed, controls enforced, and outcomes observed.

3 diagnostic questions
Example Risk

A regulator asks for evidence that a control was enforced on a given date, and the organization cannot produce it.

Example Control

Per-use-case evidence pack: approvals, DPIAs, control mappings, enforcement logs, and retention aligned to regulation.

  • Q6.1

    Can your organization produce evidence showing who approved an AI use case, what data it uses, what risks were reviewed, and what controls were implemented?

    On-demand evidence package for auditors and regulators.

    Evidence: Sample evidence pack from a live use case.

  • Q6.2

    Are AI incidents, near-misses, and control failures logged and reviewed?

    Feeds continuous improvement of controls.

    Evidence: Incident register with root cause and remediation.

  • Q6.3

    Is evidence retention aligned with regulatory and contractual obligations?

    Retention schedule mapped to regulatory scope.

    Evidence: Retention policy and enforcement configuration.

PILLAR 07

Governance Operating Model

Named accountability, escalation paths, exception handling, and policy-to-control enforcement across the AI lifecycle.

3 diagnostic questions
Example Risk

Policy exists on paper but no one is accountable for enforcing it in the platform.

Example Control

Published RACI, executive AI governance forum, and CI/CD gates that block deployments violating policy-as-code.

  • Q7.1

    Are AI governance policies technically enforced, or are they primarily documentation and training?

    The gap between written policy and runtime behavior.

    Evidence: Policy-to-control mapping with enforcement evidence.

  • Q7.2

    Is there a defined AI governance operating model with clear accountability?

    Named owners across risk, data, security, legal, and platform.

    Evidence: RACI and governance charter.

  • Q7.3

    Are governance decisions and exceptions tracked with a defined escalation path?

    Enables oversight of risk acceptance and deviations.

    Evidence: Exception register and review cadence.
