Implementation turns design into running code. We walk through the six-step field pattern for model integration: from task intent definition to Trust Ledger registration. You'll implement telemetry instrumentation with OpenTelemetry, enforce schema validation, and configure multi-tier fallback chains that include human escalation.

Next, you'll engineer adaptive routing systems with confidence gating and circuit breakers. Master cost-performance engineering by tracking cost-per-successful-decision (not tokens) and implementing policy-aware routing that automatically adjusts for latency SLOs, budget limits, and data sensitivity requirements.
