C.2.1:9.1 - Physical engineering

A pump-maintenance specification has a claim graph about exact pump P under a reference scheme that resolves part names, states, units, and measurement procedures. Those three participants identify the episteme. For test bench B, exact covered claim subgraph C_B contains the discharge-pressure-tolerance and leakage claims. Its claim-to-world mapping names the direct pressure-measurement and leakage-inspection relations involving B; a maintenance-interval claim outside C_B is not grounded by those measurements. The grounding relation over (E,B), with covered=C_B, continues for the maximal interval during which every required mapping obtains. If that coverage continues while an evidence archive or inspection-work log becomes unavailable, only a separately governed support, warrant, confidence, or evidence-use assertion may change. A publication occurrence makes the episteme available through a rendered checklist form borne by an exact carrier. When checklist marks assert particular maintenance or inspection Work, use :4.0’s Work branch; assignment attribution is added only when the checklist account requires it. A separately current assertion that P satisfies the constructive U.System criterion is another episteme about P; renaming or republishing the governing FPF pattern does not change P or create its systemhood.

The classification assertion changes only when its own claim content or reference scheme changes. Pump continuity is judged instead under the A.1 reidentification rule; a changed or unchanged assertion does not establish that continuity.
