Pumping station under flood risk

In the preceding SYSE.1 use, the engineer retains the intended referent PumpingStation-P1 in decision content and records downstream exposure as unresolved. No actual PumpingStation-P1 exists yet. The first linked proposal says:

use claim: the intended referent would move water under the selected flood load without unacceptable downstream harm
system-concept claim: the description assigns pumping, positioning, power, control, and discharge functioning to the intended station referent
main uncertainty: downstream conditions may make the proposed discharge harmful
architecture question: which selected structures and possible bearers could support the claim

This is enough to use C.30 and C.32. A component pump test can contribute evidence about an actual bearer, but it establishes neither the not-yet-present station nor its outside effect. The engineer uses downstream-harm evidence to revise the use claim. The project-system choice reopens only if the station referent no longer supports the project decision.
