E.17.EFP:5.2.c - Partial source expression and a mixed-face bundle

Source edition. In this example, ReservePathDescription-E4 concerns exact path R-1 and its overload intervals under effective duration scheme RS_duration. It contains D-31: R-1 is configured to remain available for overload intervals no longer than five minutes and T-8: Observed interval O-7 lasted two minutes.

PlainView form. R-1 is configured for overload intervals up to five minutes. Source: ReservePathDescription-E4, D-31. Use: orientation to the configured duration; this form omits the O-7 observation.

For that use, D-31 is sufficient and the form may be SourcePinnedExplanation of the same source edition. It does not assert T-8, observed availability or a guarantee. The omitted T-8 does not constitute another episteme, and the class claims no whole-source coverage.

TechCard form. O-7 falls within D-31's configured duration window. Sources: ReservePathDescription-E4, D-31 and T-8.

That connective follows from 2 min <= 5 min under RS_duration; the form may be SourceLinkedExplanationReconstruction with this derivation pointer. The bundle states the class difference. The PlainView form alone cannot answer whether O-7 fits: that use needs the omitted T-8 and must return to it. Neither comparison establishes that the path actually remained available.

Missing qualification. Suppose an identified source edition also states D-32: This availability configuration applies only while the backup supply is energized. A form giving only the true five-minute duration is insufficient for deciding whether the configuration applies during loss of that supply. Return D-32 and the supply-state facts before that use. This insufficiency creates no target episteme; a separate assertion of unconditional availability would be changed content requiring its own target and relation.

Equal words, different subject. The same duration sentence about path R-2 does not identify the R-1 source. Likewise, identical displayed duration words interpreted under another effective scheme do not establish the same source identity. Recover the exact concern and scheme and apply the relevant retargeting or scheme-change pattern before claiming a source-to-target relation.
