Planning allowance: 1–3 weeks for a bounded rollout, with subsequent ongoing ownership. Deliver the manifest, configuration, artefact hashes, evaluation harness, data dictionary, cost workbook, deployment instructions and rollback procedure. Use a staged rollout appropriate to the risk, with manual fallback where needed.
Run an export/redeployment rehearsal. Test that the buyer can retrieve adapters or weights as contractually permitted, reproduce preprocessing and execute the evaluation elsewhere. Maintain access boundaries for customer data and deletion obligations for suppliers.
Set triggers: a new document family, policy change, critical error, sustained review growth, changed provider pricing or a better practical baseline. A trigger starts diagnosis; it does not automatically authorise retraining. Keep a record of every release and why it passed.
