Function take_frame 

fn take_frame(
    surface: &ViewSurface,
    dictate: &Streaming,
    terminal: &mut TerminalViewingState,
    me: u64,
    route: FrameRoute,
)

Push one dictation frame into this connection’s takes or its read-aloud recording, recording anything else.

Every refusal is a debug record rather than a warning: a client streaming into a server that cannot take it is information about that client, not a problem forge has, and the record is what makes it legible either way.
