Inspect fusion_cloud_status, authorization owner, reviewed recipes, scope and admission budget. Never reuse native MCP tokens, distribute a client secret or request a PAT.
Choose an installed recipe and declared typed inputs. Freeze exact source versions/configuration/hashes. A generic signed activity does not constrain code, data or cost.
Use fusion_cloud_job_prepare to resolve actual dependencies and reservation. Required hard-cap or immutability guarantees remain blockers when unsupported; do not weaken them silently.
For a bounded batch, use fusion_cloud_batch_prepare with one approved recipe, frozen common source context, approved object-storage destination, a stable request key and explicit unique variant IDs. Review the whole prepared mapping before submission. fusion_cloud_batch_resume admits only the requested bounded wave of unattempted children; it does not refresh expiry, bypass per-job budgets or publish into Fusion/ERP. Use fusion_cloud_batch_inspect after interruption, and retain each child job ID for detailed status, output validation and billing.
Submit the unchanged plan with an existing compute grant and unique idempotency key. Durable intent/reservation precedes submission. Lost acknowledgments and unknown states never justify blind resubmission.
Poll the plugin job ID. Provider success remains validating until trusted output checks pass. Cancel only where qualified; cancellation is not rollback or free compute. Final billing comes from the trusted reconciliation adapter; unknown exposure retains its reservation.
Unknown validation intent or a recorded output-identity collision blocks the batch. Do not clear records, regenerate keys, revalidate to erase a conflict or submit remaining variants as a workaround. A receipt ID collision check does not prove physical storage-key isolation; that is part of the trusted stager's qualification.
Report processing, validation, artifact and cost evidence separately. Offline mocks do not establish geometry, residency, metering or service compatibility. See enterprise recipes and batch recovery.
