A.16.1:15.1 - Migration from vague cue or signal language

Source prose often says merely “there is a signal” or “something suggests possible work”. A conforming migration first asks whether the source is truly signal-like in the narrow telemetry or trace sense, or whether the load-bearing phenomenon is a broader cue nucleus, work-possibility hint, reliance-possibility hint, contrast, or figure-against-background shift. It then turns the passage into a cue pack with explicit cue nucleus, primary witness or anchor, and route-candidate hints only if those hints are already visible.
