E.11.PUA:5.4 - Pre-existing result: inspection does not reproduce it

A maintenance engineer inspects an installed pump that predates the current pattern use. Current measurements may ground the pump for a compatibility question only through the exact measurement, observation, diagnostic, or evidence-use relations defined by the applicable patterns; the historical production claim lies outside the basis.

Use PreExistingResultGroundingFinding@Context for the present grounding and cite its exact GroundingBasisPair values. An inspection note or record may describe the pump and support evidence use, but it cannot replace the physical pump or occupy the expected subject-result position. Keep producing-work provenance absent. The current inspection neither manufactures the pump nor proves how it was manufactured. If the direct grounding relation cannot be recovered, return that blocker instead of treating inspection proximity as grounding.
