Constant EXPLAIN_SINGLE 

pub const EXPLAIN_SINGLE: &str = "did not auto-approve this command. safe-chains approves \
                                  commands it has researched and has no opinion about the rest.";

The --explain header for a single command that did not auto-approve.

--explain runs against no harness, so it says nothing about what follows — the same Outcome::Unknown discipline the builder applies. It also prints the resolved profile and the refusing clause underneath, which is the detail a deliberate query can afford and an interruption cannot.
