Function next_handoff_prompt_id 

pub fn next_handoff_prompt_id() -> String

Generate a prompt id for the handoff’s procedure turn: the judgment prompt forge itself writes, which asks the handing-over session to run the handoff skill.

The extra segment sits under the machinery’s prefix on purpose. Every row that reads forge_nudge_ to tell the machinery’s words from the reader’s keeps answering the same way, while a view that knows the longer prefix draws the procedure as its own row. A client that does not know it falls back to the ordinary machinery row rather than to the reader’s own.
