#A.6.3.RT:4.5.b. Loss and reliability rule

Preface node heading:a-6-3-rt-4-5-b-loss-and-reliability-rule:12234

#What this page is

This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

#Methodology

Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

#Content

A reviewed case under this pattern makes explicit which distinctions, inspection possibilities, or local cues are lost, foregrounded, or rearranged by the shift in representation regime. Reliability transport may remain source-bounded or be explicitly downgraded, but it must never be silently widened just because the receiving form looks clearer, more structured, or more formal.
