Supported Upgrade Paths
Upgrade only across release baselines proven by the installer, manifest, migration, and rehearsal evidence.
The commercial package manifest declares a config schema version, migration expectation, target initialization requirement, and supported upgrade baseline. Upgrade only from the baseline and predecessor states proven by the current release evidence; do not promise arbitrary-version upgrades.
The complete commercial rehearsal records predecessor detection, upgrade, idempotent rerun, rollback planning, and re-upgrade in disposable environments. The exact package and manifest supplied to a buyer remain the authority for a specific target.
Verification
Compare current installation version and migration state with the target manifest. If the baseline is unknown, the database is not initialized, or required migration evidence is missing, stop before image or database mutation.
