Software and Applied Innovation

Authority first. Evidence throughout. Action last.

This reference architecture shows how Viceroy NM evaluates governed automation. It is a design pattern, not a claim that every current capability implements every control or holds an external authorization.

01 / Control layers

A reviewable path from policy to execution.

01

Human authority gates

Explicit review points separate recommendations, approvals, and consequential actions. The authorized human role and escalation path are defined in scope.

02

Attribute-based access control

Policy can evaluate user, role, data, purpose, environment, and action attributes before granting access. Exact enforcement depends on the authorized system boundary.

03

Tamper-evident event chain

A reference implementation can hash each audit event with the preceding event digest so later changes are detectable. Retention, signing, and evidence rules are set for the engagement.

04

Model and workflow evaluation

Test cases, expected outcomes, observed failures, overrides, and release criteria become reviewable evidence rather than informal confidence claims.

02 / NIST AI RMF crosswalk

Functions mapped to operating evidence.

The NIST AI Risk Management Framework organizes work into GOVERN, MAP, MEASURE, and MANAGE. The records below are practical evidence examples, not a certification.

FunctionEvidence and operating record
GOVERNRoles, policy, approval authority, risk ownership, change control, and evidence retention.
MAPMission context, affected users, system boundary, data sources, dependencies, harms, and operating constraints.
MEASURETest suites, performance thresholds, failure analysis, override rates, access checks, and audit-chain verification.
MANAGERelease gates, residual-risk decisions, monitoring, incident response, rollback, and retirement criteria.

03 / Deployment boundary

Architecture is not authorization.

This page does not represent FedRAMP authorization, a government ATO, CMMC certification, an FCL, personnel clearances, or approval for classified use. Controls, algorithms, cryptography, retention, and review gates must be specified and verified for the exact environment.


Define the authority model.

Bring the users, decisions, data boundary, permitted actions, review gates, and acceptance evidence. Viceroy NM will evaluate the architecture against that operating need.

Necessary technology is always active because it provides security and remembers this choice.
