LMS Rollback Evidence

Summary​

Migration and model-snapshot artifacts exist, but no source-backed Training rollback runbook, automated rollback workflow, compatibility window, or data restoration procedure was found.

Reference Content​

Rollback is therefore an ownership and approval boundary, not a documented executable procedure. Before any change, reviewers should identify migration compatibility, irreversible data effects, Document side effects, outbox implications, and the approved recovery owner.

Safe validation is limited to confirming the intended version, migration state category, health category, and synthetic smoke evidence. Any rollback decision Requires confirmation from service, database, operations, and product owners.

Safety and confirmation boundary​

No production command, secret, configuration value, internal address, infrastructure detail, direct data change, or replay instruction is provided. Production ownership, approvals, service objectives, alerting, and recovery authority require confirmation.
