E.17.EFP:5.2.b - Selected-method explanation with an explicit source relation

Source slice. The method-selection note chooses method M-2 because the material stays below threshold T and resource window W is available. It also says that work plan WP-17 and result measurement RM-4 remain required before and after execution.

Published explanation. M-2 is selected here because the material stays below threshold T and resource window W is available. Work plan WP-17 and result measurement RM-4 remain required before and after execution.

The selection relation and both limits are explicit in the source, so this is ordinary same-ClaimGraph re-expression; it needs no invented addedLinkPolicy. It is not evidence that work occurred, a gate decision, or engineering justification. Selection use still concerns exact U.Method M-2; planning concerns U.WorkPlan WP-17 under A.15.2; any claim that work occurred requires a dated U.Work under A.15.1. Evidence, engineering-justification, or gate use remains under A.10, B.3, A.20, or A.21 only when actually raised.
