Ruby Sessions

Use session start to establish identity and reusable defaults for policy, route, and risk.

session = client.session.start(
  agent: "refund-agent",
  subject: "customer:42",
  metadata: { channel: "support" },
  policy: { ref: "policy/default", version: "2026-02-27" },
  route: { provider: "openai", model: "gpt-4o-mini", region: "us-east-1" },
  risk: { score: 22, decision: "allow" }
)

Session Default Inheritance

• Session-level policy and route are optional
• If omitted in execute calls, DriftGate inherits from session
• If omitted in both places, backend org/workspace defaults apply

Operational Guidance

• Set subject for tenant-level attribution
• Store session ID for deterministic replay workflows
