Constant COMMIT_CYCLE_MESSAGE 

pub const COMMIT_CYCLE_MESSAGE: &str = "Policy patches repeated an exact prior candidate state.";

What: The message of a commit-path loop that repeated an exact prior state. Why: The wording is the incumbent’s, so the two paths report the same failure.

In TS you’d write (pseudocode):

const message = 'Policy patches repeated an exact prior candidate state.';
