Architecture playbook
Technical architecture depth for private, governed enterprise AI.
Use this playbook to evaluate deployment patterns, controls by layer, and the operational design needed to make AI stable in production.

Control layers
| Layer | What must be controlled | Why it matters |
|---|---|---|
| Data | Ingress, egress, retrieval scope, retention, redaction | Data boundary assumptions collapse first under real use |
| Model and prompt | Versioning, evaluation, promotion criteria, rollback | Silent regressions create costly trust failures |
| Runtime | Identity, secrets, request controls, logging | Runtime gaps become incident gaps |
| Operations | Monitoring, drift detection, runbooks, escalation | AI becomes a production system only when owned |
| Governance | Approvals, evidence artifacts, audit trail, policy mapping | Compliance cannot be retrofitted after rollout |
