| Environment and contract pin | GET /v1/partner-organizations/{partnerOrgId} | Your integration points at the intended DutyClaims environment and the same contract hash that produced your downloaded OpenAPI, starter files, and examples. | Record the target host, contract hash, and the exact generated artifacts the team used during the rehearsal. |
| Credential and header discipline | GET /v1/partner-organizations/{partnerOrgId}/capabilities | Production traffic uses the credential shape the current route family actually publishes. Do not treat sandbox OAuth as proof of a production flow. | Keep one successful authenticated read plus the rotation owner and secret-storage location for the live credential. |
| Traceability and idempotency | POST /v1/claims | Write paths send and persist `Idempotency-Key`, `X-Correlation-Id`, and the returned request identifiers so retries and support escalations stay replay-safe. | Capture one write log showing the outbound idempotency key plus the response `requestId` and `correlationId`. |
| Webhook readiness | POST /v1/sandbox/webhooks/test | The receiving service stores the signing secret, verifies the HMAC against the raw body, and routes only after verification succeeds. | Keep one successful endpoint registration plus one successful synthetic sandbox delivery and the receiving-service log entry that validated it. |
| Golden-path rehearsal | GET /v1/claims/{claimId}/status | You have run the actual flow you intend to ship, not just isolated curl calls. For most teams that means client, authority, claim creation, status read, and webhook observation. | Record the partner client ID, claim ID, and any webhook delivery identifiers from the rehearsal run. |
| Support and rollback packet | GET /v1/webhook-deliveries | On-call and partner-support teams know which metadata to include when traffic misbehaves and how to fall back during migration windows. | Prepare the escalation template with route, timestamp, request ID, correlation ID, partner org, claim/job ID, and the current cutover owner. |
