SYSE.19:4.1 - Perform the Move

1. Name the receiving decision. State the engineering decision at risk, any relied-on Work result, the current configuration and use, the relevant interval, and the action that could change.
2. Identify the source epistemes. Recover the predecessor and later claim-bearing epistemes, their applicability, provenance, and publication or carrier facts when those facts matter. Establish an edition relation only when its predicate obtains; otherwise treat the later source as a replacement candidate or record an identity gap.
3. Compare claims rather than files. State every material change in claim content or applicability—for example, proposition, scope, assumptions, limits, evidence status, or MethodDescription content. Classify the remaining differences as publication or carrier changes. When relevant meaning, applicability and access remain compatible, finish with any needed reference repair. Missing comparison facts remain a scoped gap.
4. Recover direct reliance. For each material claim, inspect candidate receiving content found by means such as search, citations, traces, or AI assistance. State the decision or Work result and the direct premise or evidence-use relation that connects it to the claim.
5. Bound the affected reach. Distinguish depends, mentions only and unresolved within the searched frame. Group equivalent irrelevant mentions; retain a short exclusion reason in the existing result when its receiver needs it. Follow a depends branch only while a downstream engineering action can still change. Use A.10.1 when several receiving uses still need discovery; retain the search coverage needed for the stated conclusion.
6. Choose any needed revalidation Work. Use adequate existing evidence first. A scoped limitation or blocked use can be the completed answer. Select further Work under C.11.DUA when its obtainable contribution warrants the complete programme burden within the receiving window. For selected Work, name the Agent, Method, configuration, conditions, evidence need, authority, cost and stop. Cost does not make an unsupported use safe or supply missing permission.
7. Perform and qualify selected Work. Identify actual performed Work and returned evidence separately. State what the result supports for the current configuration and what remains unknown.
8. Decide separately for each affected engineering decision. Assign one decision disposition from the closed set in section 0.1 and state its reason, evidence and applicable interval. Name next Work only when selected for this receiving use. A passing check becomes a decision premise only when authorized decision Work uses it.
9. Supply the result and preserve history. Give the Agent making the relevant engineering change or release decision the supported use, relevant revalidation evidence and material blockers. This direct return can finish the question. A further common account is needed only for a receiver who needs that overview. Keep earlier source editions and decisions recoverable for their original uses and intervals.
10. Stop at the completed receiving answer. Finish a compatible reference repair directly. For material change, return the qualified in-scope decisions or exact blockers and preserve independently resolved branches. A no-impact claim requires adequate discovery coverage and actual-use support; uninspected or inaccessible surfaces remain gaps.

The numbered presentation is an A.22.CGUS learning unfolding, not a lifecycle or a required Work sequence. Source comparison, design, testing, operation, and release Work may overlap. Only dependencies established for the current claims impose an order.
