Use a compact release gate before moving from architecture to production engineering.
◷ Estimated reading time: 4 min
A reliable system is not "finished," but it should meet an explicit release bar. Use this checklist to find the largest remaining gap before Chapter 5 turns the design into a production lifecycle.
Quality Evidence
Success criteria and unacceptable outcomes are defined.
Representative offline datasets cover normal, risky, edge, and historical-failure cases.
Architecture-specific metrics isolate retrieval, workflow, agent, and handoff failures.
Release thresholds and regression rules are explicit.
Security and Control
Untrusted content cannot grant authority.
Tools enforce identity, scope, parameter, and resource authorization.
High-impact actions use approval, spend, or policy gates.
Secrets, memory, tenants, and external dependencies are isolated and governed.
Runtime and Operations
Timeouts, retries, idempotency, checkpoints, and safe fallbacks are defined.
Traces connect versions, retrieval, model calls, policy, tools, outcomes, cost, and latency.
Logging is redacted, access-controlled, and retained appropriately.
Owners, escalation, incident, and user-recourse paths are named.
From Trust to Production
Chapter 4 defined the evidence and controls that make an architecture trustworthy. Chapter 5 will turn those requirements into specifications, deployment boundaries, CI/CD gates, versioning, rollout, SLOs, and operational ownership.
Key Takeaways
Reliability is a release discipline combining evidence, authority controls, recovery, observability, and governance.
The checklist should produce explicit gaps and owners—not a ceremonial approval.
Chapter 5 operationalizes these controls across the production lifecycle.
A system has strong answer-quality scores but broad unscoped write permissions. Is it ready?
Which release gate is most architecture-aware for a RAG agent?
What makes a readiness checklist useful?
What is the main transition from Chapter 4 to Chapter 5?
