# Security, Reliability, and Governance

## Purpose

This guide defines how to govern AVELIN-GPT, AVELIN-API, AVELIN-MCP, and Y-RAY under enterprise-grade trust and reliability requirements.

It establishes a single operating model for policy control, incident accountability, and continuity assurance.

## Governance Outcomes

- Safe adoption of AI in high-sensitivity business workflows
- Consistent policy enforcement across all platform products
- Faster containment and recovery during service disruption
- Strong audit defensibility through complete operational evidence
- Continuous improvement based on KPI-driven governance decisions

## Governance Principles

- Least privilege for all user and service access
- Centralized policy control across all AVELIN products
- Evidence-first reliability and trust operations
- Business continuity as a non-negotiable objective
- Governed speed: improve delivery without bypassing control quality
- Clear ownership for every critical workflow and control domain

## Security Governance

## 1) Perimeter and Access Control

- Enforce secure entry for all product surfaces
- Apply role-based access and identity governance
- Review privileged access on a fixed cadence
- Separate high-risk admin duties to reduce misuse risk
- Validate **Cross-Model MoE** cascading respects trust boundaries per tier

## 2) Data and Trust Control

- Apply anonymization controls for sensitive workflows
- Use strict retention settings where risk requires minimal persistence
- Keep traceability records for audit and legal needs
- Enforce data-residency alignment for regulated workloads

## 3) Integration Governance

- Restrict AVELIN-MCP permissions by role and use case
- Approve connector access using business ownership rules
- Monitor integration authorization quality and failure trends
- Keep explicit owners for business-critical action pathways

## 4) Intelligence Governance

- Enforce cascading policies in AVELIN-API for **Cross-Model MoE** orchestration
- Track token usage and spend patterns by function and tier
- Validate quality for high-impact reasoning workflows — ensure premium tiers (ultra/pro) used for critical decisions
- Apply output guardrails for policy-sensitive decisions
- Monitor cost efficiency: Intelligence up to 85%, Coding up to 86%, Agentic up to 87% savings vs premium alternatives

## 5) Compliance Evidence Governance

- Maintain decision-grade records for access, policy events, and critical changes
- Define evidence retention windows by risk class and governance policy
- Validate evidence completeness before audit windows
- Ensure evidence can be produced quickly during internal and external review

## Reliability Governance

## 1) Product Health Control

- Monitor readiness and continuity for each core product
- Track incident impact by business workflow criticality
- Maintain priority definitions for mission-critical workflows

## 2) Incident Governance

- Maintain clear owner model for each product area
- Use standardized escalation and communication procedures
- Classify incidents by business impact severity before remediation planning

### Incident Severity Model

| Severity | Business Impact | Response Expectation |
| --- | --- | --- |
| SEV-1 | Platform-wide critical disruption | Immediate cross-functional response and executive visibility |
| SEV-2 | Major workflow degradation | Rapid owner escalation and same-cycle stabilization |
| SEV-3 | Localized functional issue | Planned remediation with monitored workaround |
| SEV-4 | Minor defect or quality issue | Backlog fix with trend tracking |

## 3) Change Governance

- Validate configuration updates through controlled review
- Record governance impact of major platform changes
- Require rollback readiness for high-impact changes
- Verify business workflow integrity after change completion

## Governance Control Domains

| Control Domain | What Must Be Controlled | Typical Evidence |
| --- | --- | --- |
| Identity and access | Who can do what, where, and when | Access reviews, role assignment records, exception logs |
| Data privacy and residency | Where sensitive data is processed and retained | Retention policies, residency records, trust-control evidence |
| Intelligence quality and policy | How outputs are governed for critical use | Guardrail policies, quality review notes, exception approvals |
| Integration and action safety | How external actions are authorized and monitored | Connector approvals, action audit trails, failure trend reviews |
| Reliability and continuity | How critical services remain available | Health reports, incident timelines, recovery validations |
| Compliance and audit defensibility | How quickly evidence can be produced | Audit packets, evidence completeness checks, response logs |

## Governance Cadence

| Cadence | Required Activity | Expected Output |
| --- | --- | --- |
| Weekly | Product health, incident review, policy exception review | Action log with owners and deadlines |
| Monthly | Access review, token governance review, KPI trend review | Governance scorecard and optimization priorities |
| Quarterly | Strategic risk review, adoption review, maturity review | Executive governance report and next-quarter plan |

## Accountability Model

| Role | Primary Accountability |
| --- | --- |
| Platform Owner | Governance strategy, cross-product priorities, high-impact decisions |
| Operations Lead | Reliability execution, incident containment, recovery discipline |
| Security Lead | Trust controls, access posture, policy integrity, exception approvals |
| Business Leads | Workflow outcomes, adoption quality, business-impact validation |

## Decision Rights and Escalation

- Platform Owner approves high-impact policy and cross-product governance changes
- Security Lead approves trust-control exceptions and sensitive access exceptions
- Operations Lead coordinates containment and restoration during active incidents
- Business Leads validate closure for incidents that affect critical workflows

## Minimum Governance Checklist

- Access reviews completed on schedule
- Critical workflow ownership explicitly documented
- Policy exceptions time-bound and approved
- Incident postmortems include prevention actions
- Evidence readiness validated before audit windows
- KPI reviews produce tracked corrective actions

## Key Governance KPIs

- Security and trust incident trend
- MTTR and availability trend by product
- Share of workflows completed through governed channels
- Token governance quality and cost efficiency trend
- Audit evidence completeness and response readiness
- Policy exception aging and closure rate
- Data-residency conformance for sensitive workloads
