SYSE.33:4.5 - Exercise clean creation, change and partial failure

Create an environment from the retained description without relying on the original machine’s hidden setup. Observe the actual resources, effective configuration and dependency reachability, then run the representative task. A successful provisioning job without the task result establishes less.

Change one relevant configuration and verify both the intended new condition and the continuing task. If a manual intervention was needed, either make its necessary effect part of the supported procedure or identify the still-manual dependency. Do not let a reconciler and an unrecorded repair repeatedly undo each other.

Exercise a consequential partial-creation failure. Recover the actual effects before retrying, then reconcile, remove or retain them under the applicable permissions and data conditions. An unavailable observation leaves partial state unknown; it does not mean nothing was created.

Return the description/procedure, actual exercised environment, supported task and conditions, lifetime/support arrangement, and any remaining gap. Existing configuration and operating records can carry these facts; the pattern does not require a new inventory system.
