A.4:5 - Archetypal Grounding

A.4:5.1 - One continuing pump, two selected design accounts

In this constructed case, Pump37 operates under condition set C. A justified domain comparison uses exact flow values in L/min under those matched conditions. The available observation is 105. Account D1 requires at least 100; account D2 requires at least 110.

Selected basis	Comparison	Bounded result
D1, C, minimum 100 L/min	105 ≥ 100	This flow requirement is met.
D2, C, minimum 110 L/min	105 < 110	Flow misses this requirement by 5 L/min.
D2 under C, observation under C′, with no justified translation	The comparison premise is missing.	Unresolved comparison, not a failed pump or a false design.

Selecting D2 changes the comparison basis; it does not physically change Pump37. Editing D1 into D2 changes the account’s claim content. Its historical edition relation, if claimed, must independently obtain. The discrepancy against D2 may justify a later response question, but supplies neither change authority nor a requirement to revise the design.

A.4:5.2 - Distinguish the actual event and its next use

Working situation	Correct exit
A pump circulates coolant while its CAD account is edited.	Use the continuing pump and the selected CAD account claim in the comparison. Operating Work and editing Work concern different subjects; the edit establishes no physical pump change.
An author cites an unchanged theorem.	Use the direct episteme-use rule. The theorem executes no OperationalMethod; any reasoning Work has its own performer and Method.
An unused pump weathers.	A.3.4 can qualify the actual material change without invented Work. If later design conformance matters, compare the resulting condition with the selected criterion.
A sensor measurement produces a new observation record.	Use the observation as warranted input to the comparison. Measurement and result do not by themselves establish target change.
A pump’s internal control System performs maintenance.	A.12 distinguishes acting and changed participants. The System’s identity rule can preserve the same pump; compare its relevant resulting facts if the intended use requires it.
