SYSE.11:4.1 - Perform the Move

1. Name the System and use. State the actual System, starting configuration, receiving use, affected Systems, operating envelope, interval, and deciding Agent.
2. Choose the increment boundary. Include only the changes whose joint actuality is needed for that use—for example, changes to physical parts, software, descriptions, procedures, or interfaces. Keep omitted changes, alternatives, and fallback visible.
3. Check the required inputs at the time of use. Use input results—for example, realization, platform, constituent-coordination, configuration, or specialist results—only for matching subjects, configurations, uses, horizons, and evidence windows. Close unsupported branches, replace them with qualified sources, or retain them as blockers. Evidence obtained from later Work cannot support an earlier input retroactively.
4. State completion and evidence conditions. For each included change, name the transformation, integration relation, resulting configuration claim, observation or test, unacceptable result, and stop. A planned check or tool status alone does not establish that the change or integration occurred.
5. Perform Work and identify actual change. Record the performing Agents, dated Work, assignments when relevant, enacted Methods, subjects, results, and evidence. Identify the actual transformations separately from Work and from descriptions of either.
6. Integrate and observe. Establish every relation needed by the selected configuration, including any required physical, software, interface, or operating relation. Observe the named use under the declared conditions; do not infer containing-System behavior from a component test without the needed correspondence.
7. Assess usability narrowly. State which use claim is supported for which configuration, conditions, and interval; name unsupported claims and the fallback. Obtain each separately governed assurance, permission, release, or specialist result when the receiving decision needs it.
8. Choose later change only when needed. If an option such as repair, extension, replacement, rollback, further observation, or no current change is justified by what it contributes, use C.11.CRC for the finite configuration comparison and C.11 for the choice. Record the selected option, retained alternatives, evidence trigger, and claim that later observations can reopen.

This is an A.22.CGUS learning unfolding, not a calendar order. Work may overlap, but a decision can rely only on results already established for its subject and conditions.
