Governance by Design

Structural enforcement, not procedural compliance.

Why Structure Matters

AriaOS enforces governance through system architecture, not policy documents. Constraints are built into the execution layer. Violations are blocked at runtime, not flagged for review.

Fail-Closed by Default

When audit health degrades, policy compliance fails, or profile authorization cannot be verified, the system defaults to Human-In-The-Loop mode. Autonomous execution halts automatically. No operator intervention required.

Structural Enforcement Mechanisms

Profiles

Operator profiles define maximum authority, permitted actions, and resource access limits. Profiles are assigned per operator and cannot be self-escalated.

What Profiles Control

  • Maximum autonomy level (HITL, Advisory, or Constrained Autonomy)
  • Access to system resources, data domains, and control interfaces
  • Authorization to approve high-risk actions (policy changes, autonomy escalation, resource deployment)
  • Visibility into audit logs, system state, and governance metrics

Profile Enforcement

  • Profiles are validated at every action request
  • Expired or revoked profiles immediately block execution
  • Profile changes require administrator authorization and are logged immutably
  • Operators cannot modify their own profile authority

Policy Gates

All actions—human-authorized or autonomous—must pass policy compliance checks before execution. Policy violations halt execution immediately and trigger operator alerts.

Policy-Gated Actions

  • Autonomy level escalation or reduction
  • Resource allocation beyond profile limits
  • Data access outside authorized domains
  • Workflow execution that violates mission parameters or Rules of Engagement (ROE)

Policy Enforcement

  • Policies are evaluated before action execution, not after
  • Violations trigger automatic halt and operator notification
  • Policy changes require governance board approval and audit logging
  • No policy bypass mechanism exists, even for administrators

Audit Health Checks

Constrained autonomy requires continuous audit health verification. Loss of audit integrity immediately disables autonomous execution and reverts to Human-In-The-Loop mode.

What Audit Health Verifies

  • Immutable event log is accessible and has not been tampered with
  • Timestamps are synchronized and verifiable
  • All autonomous actions have complete reasoning traces and justification metadata
  • Audit log storage has not reached capacity or become corrupted

Fail-Closed Behavior

  • If audit health check fails, autonomous execution halts immediately
  • System reverts to HITL mode until audit integrity is restored
  • Operators are alerted to audit degradation with specific failure reason
  • Autonomous execution cannot resume without operator verification of audit recovery

Supervisor Enforcement

The supervisor layer monitors agent behavior and enforces process-level constraints. Supervisors detect violations, isolate misbehaving agents, and trigger recovery workflows.

What Supervisors Monitor

  • Agent resource consumption (memory, CPU, network bandwidth)
  • Action execution against profile and policy constraints
  • Anomalous behavior patterns or unexpected state transitions
  • Inter-agent communication for unauthorized coordination or command injection

Supervisor Enforcement Actions

  • Isolate agents that violate constraints or exhibit anomalous behavior
  • Halt execution and alert operators when policy violations are detected
  • Trigger autonomous recovery workflows for detected failures
  • Log all enforcement actions with reasoning and agent state snapshots

Fail-Closed Behavior

When any governance mechanism fails—profile verification, policy compliance, audit health, or supervisor monitoring—the system defaults to the most restrictive operating mode. No execution proceeds until integrity is restored.

Fail-Closed Scenarios

  • Profile cannot be verified → Action request denied, operator alerted
  • Policy compliance check fails → Execution halted, violation logged
  • Audit health degraded → Autonomous execution disabled, revert to HITL
  • Supervisor detects violation → Agent isolated, workflow paused

Recovery from Fail-Closed State

  • Operator must diagnose root cause of failure
  • Integrity must be restored (profile renewed, policy corrected, audit recovered, agent fixed)
  • Operator must explicitly authorize resumption of constrained autonomy
  • All recovery actions logged with justification and verification metadata

Governance vs Procedural Compliance

Traditional compliance relies on policy documents, training, and post-incident review. Governance by design enforces constraints structurally. Violations are blocked before they occur.

Aspect Procedural Compliance Governance by Design (AriaOS)
Enforcement Point Post-incident review Runtime execution blocking
Violation Handling Flagged for later investigation Immediately halted and logged
Authority Source Policy documents and training Profile and policy gates enforced by system architecture
Audit Trail Manual logging, potentially incomplete Immutable, tamper-evident, continuous verification
Failure Mode Violations may proceed if not detected Fail-closed: execution halts automatically if governance integrity degrades
