E.17.EFP:5.4.c - Boundary to lighter explanatory note with source-bearing return

Source slice. The technical incident note says the reserve path remained available during the measured load band, but it also keeps one unresolved ambiguity about recovery latency.

Lighter explanatory rendering. In plain terms: the reserve path stayed available during overload recovery.

For a use that needs the measured load band or the unresolved latency qualification, this lighter text is insufficient: return those source conditions. Omission alone does not constitute another episteme. If the text is instead intended to assert availability throughout overload recovery beyond the measured band, it makes a changed claim. Identify that target under C.2.1 and establish its A.6.3.CSC or other applicable source-to-target relation before EFP classifies a later target form.
