Treat a tested rollback path as part of the upgrade, not as an afterthought.

Evidence tier describes my hands-on relationship with the content. Official sources describe platform contracts/documentation. Production observations should not automatically be treated as official limits.
Problem
Container images and configuration can be rolled back quickly while persistent state migrations may not be reversible.
Approach
Capture application state, versions and config before upgrade; verify restore procedures and define the rollback decision point.
Consumes time/storage
Prevents many fast upgrades from becoming long recoveries
