Deterministic
Designed for repeatable verification under the same declared verification context.
Underlying Assurance Technology for AEGI Shield
AEGI Core
Supporting AEGI Shield, AEGI Core provides deterministic, scope-bound evidence assurance for declared workflow evidence.
See Demonstrated EvidenceWhy Core exists
Keep evidence reviewable as AI-supported workflows change.
AI-supported workflows can produce recommendations, review states and evidence across changing models, policies and system contexts. Core provides a stable assurance discipline without taking decision authority from the operating institution.
DECLARED INPUTDeclared outcome + declared evidence + declared scope→ASSURANCE CONSEQUENCEDeterministic, scope-bound evidence assurance
What Core provides
Four public assurance properties.
An architectural consequence and review-value explanation only. Construction mechanics remain non-public.
Scope-bound
Verification remains within the declared scope rather than silently expanding what is being claimed.
Evidence-focused
Core supports evidence defensibility by verifying declared evidence within scope; business and model decisions remain separate.
State-separated
What the declared evidence supports remains separate from verifier, deployment and trust status. Institution decision authority remains separate.
Relationship to Shield and the institution
Three distinct responsibilities.
Core assurance spans the workflow while Shield and the institution retain their separate roles.
Creates risk value
Cross-risk review context and governed proposed change.
Retains authority
Consequential action and every production-change decision.
Provides evidence assurance
Deterministic and scope-bound for declared workflow evidence.
Responsibility boundary
Evidence assurance keeps roles distinct.
Core supports reviewability while risk interpretation, consequential authority and business evaluation remain institution-owned.
Risk interpretation
Model owners, analysts and the institution remain responsible for interpreting fraud and credit risk.
Consequential authority
Customer actions and production changes remain governed by the institution.
Business evaluation
Customer-specific value and suitability are assessed through the agreed evaluation and approval processes.
DEMONSTRATED BOUNDARY
Selected mechanisms—not full Core conformance.
The frozen RUN-SCE-001 demonstration exercises selected AEGI mechanisms and evidence controls. It does not by itself establish full AEGI Core conformance or production readiness.
