Raw fetch requests should not be transformed

Editor assessment

`fix: raw fetch requests should not be transformed` states the exempted request class and the stopped behavior precisely; a transform or dev scope would have localized it but the terms already do. Fix fits a mis-applied transform. The footer `fix #1433` is well-formed token-hash-value and links the report. No body explains what corrupting transformation raw fetches received — the instructive detail — but the subject fully determines the rule for a fix this size. Imperative-equivalent modal phrasing, period-free. Minor rationale gap; clear and publishable.
